Before open machine,frist check all parts waste things, to clean it.then

slowly running machine without paperboard.

2. Before feed paperboard,should frist lefting the paperboard lefting

forme,then put paperboard,then adjust the baffle in right position.

NOTE:

1.Each paperboard feed should not to much, small paperboard height

more than 300mm.big paperboard height not more than 250mm.

2
2.Back baffle should have 4-6pcs paperboard left on the work

table.others inside.

3.The rear bumper is carefully controlled during the forward and

backward movement to avoid collision with the front and rear baffles of

the workbench. Or collide with the rear limit block, damaging the

walking motor and the coupling.

4.According to the size of the cardboard, the number of dampers should

be opened appropriately. Generally, all the suction parts contact the

bottom surface of the cardboard. The cardboard is basically in the

middle of the workbench. The larger the contact area, the better. When

adjusting the air door, first pull out the positioning handle and then turn

it. Adjust to the proper position according to the arrow, and then insert

the top of the positioning handle into the positioning hole.

III . Mechanical operation

24
1、The operation of the feeder unit
(1) .Adjust the front door: it should be fixed at the right place (about 70%

of the width of the cardboard). The clearance of the front door should be

1.5 times the thickness of the cardboard.

(2)Adjustment of rear baffle and paper feeding plate.

When the cardboard is placed on the table, the gap between the front door

and the backboard is 1-2mm larger than that of the cardboard, so that the

paperboard can be delivered smoothly. If the gap is too large, the

cardboard falls to the paper pushing plate, and the excessive force will

cause the cardboard offside to produce paper feeding error.

(3) Side baffle: adjust the side baffle to make it aligned with the left and

right sides of the cardboard.

(4) .Paper feeding roller: the lower feed roller is a steel pattern roller, the

upper roller is a rubber roller, the gap between the feed rollers is adjusted,

so that the paperboard can be sent to the printing department smoothly.

(5)The adjustment of air suction:

In order to make the cardboard into the printing section smoothly, the

machine is equipped with a suction device. The suitable wind force the

paperboard on the worktable smoothly and then push the paperboard to

the paper feed roller by the paper pushing plate.

The size of the air volume is adjusted by the throttle switch, and the

reasonable air volume should be adjusted according to the thickness, size

25
and quality of the cardboard.

2、Operation of the printing unit

(1)Feeding paper press wheel: the lower roller is a steel pattern roller, the

upper paper feeding roller is a tread roller, and the gap between them is

adjusted to make the paper feed function. The printing idler adjusts its

clearance to allow a suitable gap between the plate and the pressure roller

to achieve satisfactory printing results. The clearance of the pressure

roller is usually adjusted to be less than 0.3mm of the thickness of the

cardboard, and with the superposition and printing of each color, the

pressure of the rear color is about 0.05mm larger than that of the previous

color.

(2)Through the control of cylinder movement by solenoid valve, the

anilox roller can be contacted or separated from the printing plate.

(3)Hanging plate

Press the press bar to press the edge of the plate to the plate slot, pay

attention to whether the axial position of the print roller is in accordance

with the requirements, the direction of the plate is correct, the general

situation is based on the center of the printing roll, and then turns the

printing roller against the clockwise direction. After a week, the other

side of the printing press is pressed into the ratchet on the other side of

the printing plate. In the slot on the shaft, then use the spanner to turn the

ratchet mechanism six clockwise.

26
(4)The edition of the edition of the edition house on the
base of the tablet:
The center of the whole and half page of the printed rubber pattern must

be roughly aligned with the full and half version of the base phase center.

After that, the printing plate can be adjusted correctly when printing the

preset position. It plays an important role in the machine data of preset

bits, and the printed data are built on this basis.

(5) The grinding of the printing roller:

The amount of grinders should be controlled within the diameter of 4mm.

Refer to appendix C printing shaft.

3、The operation of the slotting unit

( 1 ) Function: the machine can finish pressing, grooving, cutting

corners and dividing edges at one time. The size and position of the

grooving can be adjusted by electric power.

(2) Adjustment of slotting position

The adjustment tool is done by the electric button. There are two buttons,

one is on the slotting control panel, one is on the cross beam, and the

other two can complete the same action. According to the size adjustment

knife, press the button on the cross beam, the visual tool can be rotated,

and the ruler on the cutter head is provided with a ruler, and the knife is

adjusted according to the size.

(3)Adjustment of the pressing wheel

27
The size of the pressing line is positioned at the same time when the slot

size is adjusted. Adjust the depth of the pressure line, adjust manually

through the worm wheel body, adjust the gap with eccentric gear, and

mark it with scale.

(4) Adjustment of the knive

When three and five layers of cardboard are made, the gap between the

knife and the knife is different. The gap between the three layers is

smaller than that when the five layer is made. The reason is that the slot

cutter seat is equipped with the cutting board of the cutter, and it is

attached with the function of the cardboard. The clearance adjustment can

be manually adjusted through the worm wheel body, and the eccentric

gear is used to realize the adjustment of the gap, and the scale is marked.

At the same time, pay attention to the location of the corner cutter, and

adjust it at the same time.

(5) Adjustment of the press wheel

In the middle of the press and slotting, there are four pressure wheels to

carry the cardboard. The adjustment clearance can be adjusted manually

by the worm wheel, and the clearance is adjusted with eccentric gear, and

the scale is marked.

IV. Debug of printing press


When the printer is debugged, the current size of the adjusting

28
mechanism and the correction size of the zero position should be

determined first, and then the test printing can be carried out,

otherwise the mechanism may be damaged.

1、Power and compressed air

Press the main operating panel "power on" switch to connect the power

supply. (before switching on this switch, check carefully whether all

switches are connected.)

Turn on the air compressor switch and run for a certain time to keep the

pressure of the air tank at 8-10kg/cm, so as to ensure the gas consumption

in all parts.

2、Adjustment of ink roll and ink scraping (rubber) roll

Prepare the fast drying ink required for each color 8-15kg. Thoroughly

stir the ink in the tank and then pour it into the pail. The ink occupies

about 80% of the barrel capacity, and then insert the barrel into the

corresponding part of the printing department to insert the hose.

The adjustment of the scraping ink (rubber) roll:

The gap between the ink (reticulated) roll and the scraping ink (rubber)

roller is realized by the adjusting structure of the curet roller, and the gap

between the two rolls is 0. (attention, when the two rolls are without inks

or water in the case of no gap, do not turn the roller or open the machine

when the machine has no ink or water, and will damage the scraping ink

(rubber) roll).

29
3、The system of ink supply

Ink pump is the main component to provide ink when printing. If the ink

pump does not work after ventilation, please press the finger at the

exhaust port of the pump body and let it open after 2-3 seconds. After 3-4

repeated operations, the ink pump can be started, and the flow of ink is

large and can be achieved through the regulating valve (2).

If the stroke of the pump is too large, it will affect the shortage of

30
compressed air, cause the other pneumatic original work is not normal,

the work of the main engine is not normal, so the pump stroke must be

adjusted to the ideal position.

If the amount of ink flowing to the roller and the roller is too large, the

ink will overflow and dirty the machine, so adjust the ink quantity

appropriately.

4、The adjustment of the ink roll and the preparation of the printing

plate:

Check whether the gap between the scraper roller and the inking roller is

adjusted, and check whether the ink is evenly distributed on the surface of

the ink roller.

When the main engine rotates, the adjusting shaft is rotated through the

handle of the rotary wheel, so that the ink roller is directed towards the

printing plate, and carefully observe whether the printing plate is evenly

coated with ink.

5、Test printing

Once the various parts of the machine have been adjusted, you can put the

paper on trial, first try one or two sheets, check the printing color and

grooving position, etc.

6、Continuous paper delivery

A, the paper is stored on the paper feeder, the average height of the paper

should be about 400mm. In the process of operation, the paper can not be

31
overloaded, or the paper failure will occur.

B, in accordance with the operating procedures of the machine and paper

printing, in the printing process, do not easily improve or reduce the

speed of printing, the best operation at normal speed.

C, during operation, if the color or slotting is seriously disturbed, the fault

may be caused by slip of the paper board, and check the spacing between

the printing plate and the paper feeding roller.

7、Speed of operation

A, and gradually improve the working speed of printing presses. In order

to prolong machine life and improve printing quality, printing speed can

not be suddenly raised.

B, according to the size of the paper, the quality of the paper and the

printing situation, and so on, as far as possible to use the appropriate

balance of the printing speed operation, such a best printing effect,

sometimes even slightly increased a little speed, but the paper feeder is

wrong, forced to return paper or color modulation, resulting in a decline

in production efficiency and not the result. Improve.

C, operating speed and printing concentration

Due to the characteristics of fast printing, ink output will change with the

printing speed, making ink stains or deep or shallow on printed matter.

The depth of printing is not adjusted by adjusting the amount of ink, but

is adjusted by adjusting the viscosity of the ink.

32
IIV.Maintenance and maintenance of the machine

Machines often operate in the state of high speed automation. If

there is not enough maintenance and inspection on the machine, the

precision of the machine will be affected, which leads to the decline

of printing quality. It will shorten the lifespan of the machine, and

the requirements for maintenance and inspection are as follows:

1、 General maintenance and maintenance

★In the maintenance of the equipment, we must comply with the rules

of the operation of the machine. It needs to be specially reminded: to

avoid direct contact with the rotating part of the hand, we must press the

self locking switch when entering the machine. Be careful not to be

bruised in the hand. Take care of skidding when cleaning the machine.

★Analyze the record regularly and find the hidden trouble

2、Routine maintenance and maintenance

Each production equipment is made up of thousands of parts, including

34
many parts that need movement. For example, bearing, gear, rack, chain,

sliding guide, slide key, screw rod, sliding bearing, etc. In order for these

parts to work properly and to extend their service life, they must maintain

clean and good lubrication conditions. The maintenance of equipment is a

necessary guarantee for improving the efficiency of production of

qualified products. It can reduce the cost of maintenance, reduce

production costs, reduce the time of less downtime, improve the

utilization of equipment, improve the clean and sanitary of the machine,

and reflect the image of the company, and also reflect the user's spirit.

Therefore, it is the responsibility of every operator to maintain the

equipment well.

(1)Station refueling products:

Various gear boxes, deceleration boxes and rack, guide rail plus 68#

mechanical oil, various bearings with refueling mouths plus 3# calcium

based lubricants, and air compressors with different compressed oil

according to local climate and seasonal changes.

(2) Tools to be used for maintenance of equipment

Use 1, oil pot 2, fuel gun 3, long handle brush 4, rag 5, flat mouth knives

6, broom 7, other special tools, etc.

(3) Cleaning agent for maintenance of equipment

Wash cleaning system can be used, stainless steel plate can use diluted

alkaline solution (concentration 5%), various shaft types can use oil and

35
detergent, avoid the use of alkaline solution. The surface of the machine

can be washed with detergent and no lye is allowed.

(4)What is the right amount of refueling?

★When the oil is added, the oil cup should be filled. Gear box,

reducer, added to the upper and lower limit of the oil mirror. General

sliding guide type refueling volume shall not be spilled.

When grease is added, the bearing can be seen until the shaft grease

is pressed out, and the fuel gun of the bearing can not be seen to hit about

fifteen or so.

(5) Refueling cycle

Oil is added two times per class (morning and noon). Check the oil

consumption every day in the gearbox, replace it every time, replace it

every six months. The grease is added every two weeks.

(6)How can the pneumatic system be used correctly?

The air compressor air compressor switch is adjusted to 0.9Mpa, and

the total pressure regulating valve is adjusted to 0.5 to 0.6Mpa. Every day,

the bottom valve of the compressor should be opened and drained. The

gas and water separator should be opened and drained. Every day, check

whether there is any oil in the mist sprayer. Check the compressed air

pipe, valve and cylinder at any time. If the times are to be decorated and

recorded in the equipment running record, check the oil volume of the air

compressor crankcase every day enough, replenish the compressor oil

36
when insufficient and clean the compressor air filter once a month.

(7) Use of screws

When choosing all kinds of screws, you must pay attention to

choosing the right length. Too long will not lock the workpiece at the top

and bottom. Serious quantity will cause the sliding teeth and the top crack

parts. Too short time will cause insufficient strength, easy to loose and

cause danger. It is better to use the wrench to twist the six angle nut, so

the opening must be suitable so as not to slip angle. When you screw the

six angle screws, you must first excavate the dirt inside the six corners,

and do not use the inner six angle wrench that wears the fillet.

(7)It is strictly forbidden to use hard objects barbaric

percussion to adjust the size.

Wood hammer or rubber hammer can be used when it is necessary.

(8) About the motor

It can't be covered with sundries so as not to affect heat dissipation.

(9)Various electrical buttons

It must be lightly pressed or lightly twisted, and the charged parts can not

be damped by water or oil, so as to avoid electrical short circuit and cause

danger. Special attention should not be given to touching or touching the

screen, otherwise the touch screen will be damaged.

(10)Replacement parts

When replacing parts, pay attention to the installation position of the

37
original parts, do not install reverse, or cause too much error when

reinstalling. Installation of datum plane requires dry, choose the right

length of screws, fastening not to exert too much force.

V. Use of ink and printing plate

Water based ink is used in Corrugated Paperboard Printing for a period of

time and has been in China for several decades. Corrugated paper is made

of lead print (Tu Yin), offset printing (flat print), flexible print printing,

flexible version of water-based printing, flexible version of water-based

ink also from rosin maleic acid modified resin series. From the rubber

plate to the resin layout, the printing press also gradually becomes a three

or four color high speed printing machine from the single or double color

of the large roller, and the reticulated roll is gradually transformed from

150~200 mesh metal roll into 180~250 mesh ceramic rolls. The use of

41
sex ink is very important. Before we discuss the use of water-based ink,

we should first understand the characteristics of water-based ink and the

relationship and influence of various factors in printing, such as plate

factors, paper factors, reticulate roll factors, mechanical factors, ink and

ink factors and operating workers.

1.Characteristics of water-based inks (used on corrugated paper)

General classification of water-based ink

Water based ink is roughly divided into two categories

A: Rosin - maleic acid modified resin series

B: acrylic resin series

3. The processing methods and requirements of the flexible version

(1) processing method

A)When transporting and storing unexposed flexographic raw

materials, they need to be laid flat.

B )The maximum number of flexographic plates per time should not

exceed 14 boxes (in the same size). It is recommended that every 7 boxes

should be separated by wood panels of the same size.

C)In case of a different size package, a plate with the same size

should be separated from the bottom with the same size, and a smaller

size can be added to the layout.

D)The temperature of the preservation plate should be 15℃~20℃,

45
and the corresponding humidity is 55%.

E)Note that no other materials and sundries should be placed on the

flexible layout, nor should you sit on the box.

(2) A clear print is required and the back position is deep enough

A) clear print, the reverse position is deep enough.

B) stable base, not too thick or too thin.

C) good springback performance.

D) the hardness is moderate.

E) the rate of dot enlargement is too small.

3.Requirements for the performance of ink and wash

A) after long-term storage, it is easy to disperse after stirring.

B) have good flow performance and viscosity.

C) good storage stability.

D) drying is fast and appropriate.

E) can not have any influence on the printing press and printing press.

F) can't have a strong irritation smell.

4.Technical parameters of water-based ink:

A) viscosity: (20 seconds + 5 seconds)

Instrument: RLGOSHA CUP4 Japanese system

Note: the special ink is based on actual demand, and the standard is

less than ± 2 seconds.

46
B) fineness: < 20 micron

C) pH value: 8 to 9.5 (the best value is 8.5 to 9.2)

DIGITAL PH/MU METER SUNTEX TS-1

D) color and Standard Version

Note: contrasting the sample with the standard sample and

unconnecting the 120 color developing instrument.

E) environmental protection: in line with world environmental

protection standards.

5.The correct use of water-based ink

A) should be fully stirred before use and keep ink and ink components

uniform.

B) after opening, the ink should be sealed to prevent dust and dry up.

C) ink should be filtered before mixing with new ink.

D) during storage, avoid exposure to high temperature or hot sun. Under

normal conditions, you can store the year without deterioration.

E) if the ink viscosity is slightly larger, appropriate water can be adjusted.

NOTE ;

(1) ink usually reduces its viscosity when stirred, and it will restore

viscosity after a period of static release.

(2) the ink tank is circulate for about 5 minutes and then measured again.

(3) attention should be paid to the 0.2 to 0.5% degree of ink.

(4) when the tackifier is added, it must be added slowly and stirred evenly

until it reaches its viscosity.

(5) the hardness of the rubber plate should be 420 ±30 when it is used

for wide surface printing. It is suitable for the right side, and the fine

character and the dot should be 600 ±30

(6) rubber aging, elasticity loss, Anilox-Rdler mesh wear and so on.

(7) the press of the bottom color, reduce the bottom as far as possible.

(8) the difference viscosity of the two color is at least 5 seconds.

(9) the correct expression of liquidity refers to the pressure and friction

speed of the ink.

(10) the pH value of the ink is between 8 and 9.2, and the ink is the most

stable.

8、Conclusion

To sum up, the quality of corrugated cardboard printing depends on many

factors, and the use of ink and plate is also one of the important factors.

56
With the rapid development of printing technology and the renewal of

printing equipment, the water-based ink will develop in the direction of

high concentration, low viscosity, weak volatility and strong permeability.
