Description
Technical field
The utility model relates to a kind of cylinder clutch mechanism of offset press.
Background technology
Printing enterprise need require to renew forme in the production of using the offset press printing printing according to printing, and when beginning to print, " white edge " phenomenon appears in several Zhang Yinpin that usually can run into the front, thereby these printed sheets all are waste products.Influence may be little when this phenomenon occurred in the printing of long version, but under the increasing situation of printing of short run now, the waste that " white edge " causes is just very important.The reason that produces " white edge " is: rubber cylinder is to carry out one step completed (see figure 1) by a cylinder 3 with the combined pressure of plate cylinder, impression cylinder respectively, this mechanism also comprises connecting rod 1, rocking arm 2 and shakes pin 4; side of rocking arm 2 is connected with the lower end of connecting rod 1; side that shakes pin 4 is connected on the fixed axis 6; another side that shakes pin 4 be connected one vertically to thread spindle 7 on, the intermediate ends of shaking pin 4 is connected with cylinder 3.According to rubber cylinder 10 respectively with the arrangement mode (see figure 2) of plate cylinder 20, impression cylinder 30, when the breach 100,200 of rubber, plate cylinder has alignd, rubber, impression cylinder breach 100,300 do not have alignment, vice versa.Addressing this problem must be in the breach alignment punishment time combined pressure of breach alignment place of rubber, plate cylinder and rubber, impression cylinder.Because twice response time of the magnetic valve of control cylinder can't coordinate with the time of covering two breach, therefore was difficult to realize if finish the gradation combined pressure by a cylinder.Therefore some overseas enterprise adopts in parallel placement of cylinder of two different strokes to realize combined pressure twice, though this scheme has solved the problems referred to above, need take very big space.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of prior art, a kind of cylinder clutch mechanism of offset press to be provided, and it is simple in structure, and utilization is convenient, saves the space, can eliminate the white edge phenomenon of printing, has improved production efficiency.
To achieve these goals, the utility model adopts following technical scheme: a kind of cylinder clutch mechanism of offset press, comprise from top to bottom the connecting rod that connects successively; rocking arm; cylinder and shake pin; the eccentric bearing block of the upper end of described connecting rod and the rubber cylinder of described offset press; the centre of described rocking arm is provided with a fixing rotating fulcrum; a side of described rocking arm is connected with the lower end of described connecting rod; a described side that shakes pin is connected on the fixed axis; described another side that shakes pin be connected one vertical to thread spindle on; wherein; described cylinder is made up of first cylinder and second cylinder; both make progress with one; back-to-back series system connection that another is downward; the piston rod of described first cylinder is connected with another side of described rocking arm, and the piston rod of described second cylinder is connected with described intermediate ends of shaking pin.
The cylinder clutch mechanism of above-mentioned offset press, wherein, described first cylinder and second cylinder are two-way cylinder also respectively by a solenoid control.
The cylinder clutch mechanism of above-mentioned offset press, wherein, the piston rod of described first cylinder is connected with another side of described rocking arm by an oscillating bearing.
The technical scheme of the cylinder clutch mechanism of offset press of the present utility model, adopt the cylinder series connection of two different strokes to place, and control respectively by two magnetic valves, breach alignment punishment at breach alignment place of rubber, plate cylinder and rubber, impression cylinder realizes rubber, plate cylinder combined pressure and rubber, impression cylinder combined pressure twice, thereby has eliminated " white edge " phenomenon.The advantage that the cylinder clutch mechanism of offset press of the present utility model also has is simple in structure, the utilization convenient and save the space.

Fig. 2 is the position view of rubber cylinder in the offset press, plate cylinder and impression cylinder;
Fig. 3 is the structural representation of the cylinder clutch mechanism of offset press of the present utility model.
The specific embodiment
Explain the utility model below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 3, the cylinder clutch mechanism of offset press of the present utility model comprises connecting rod 1, rocking arm 2, the cylinder 3 that connects successively from top to bottom and shakes pin 4.Wherein:
The upper end of connecting rod 1 is connected on the eccentric bearing block 5, interior round center of this eccentric bearing block 5 51 and cylindrical center 52 decentraction, and its interior circle is enclosed within the axis coinciding that makes circle center 51 and rubber cylinder 10 it in the rotating shaft of rubber cylinder 10 of offset press;
The centre of rocking arm 2 is provided with a swing fulcrum, and its side is connected with the lower end of connecting rod 1, and another side connects cylinder 3;
A side that shakes pin 4 is connected on the fixed axis 6, another side that shakes pin 4 be connected one vertically to thread spindle 7 on, the high and low position of this side is adjustable, and the position of regulating this side can make sleeve mechanism adapt to the requirement of different-thickness paper to different printing pressure;
Cylinder 3 is made up of first cylinder 31 and second cylinder 32 and is controlled respectively by two magnetic valves, both be with one upwards, another downward back-to-back series system connects; The piston rod of first cylinder 31 is connected with another side of rocking arm 2 by an oscillating bearing 310, and the piston rod of second cylinder 32 is connected with the intermediate ends of shaking pin 4.
The operation principle of the cylinder clutch mechanism of offset press of the present utility model is: stretching out or withdrawing of first cylinder 31 or second cylinder, 32 piston rods all can drive rocking arm 2 rotations, by rocking arm 2 pullings or promotion connecting rod 1, connecting rod 1 spurs or promotes eccentric bearing block 5 again, can rotate around the cylindrical center 52 of eccentric bearing block 5; Eccentric bearing block 5 is fixing by two briquettings 81,82, and when connecting rod 1 pulling or impeller-hub bearing 5, cylindrical center 52 is motionless, but the position at the interior round center 51 of eccentric bearing block 5 is changing.Because the interior round center 51 of eccentric bearing block 5 and the axis coinciding of rubber cylinder 10, so the axle of rubber cylinder 10 also changes with the change in location at circle center 51 in the eccentric bearing block 5, thereby changed between rubber cylinder 10 and plate cylinder 20 and the impression cylinder 30 apart from (see figure 2), realized the clutch pressure.Cylinders retract is the combined pressure state.Be chosen in the breach of rubber cylinder and plate cylinder when relative, control the piston rod withdrawal of first cylinder 31, finish the combined pressure of rubber cylinder 10 and plate cylinder 20.After cylinder turns over certain angle, when rubber cylinder aligns with the impression cylinder breach, control the piston rod withdrawal of second cylinder 32, finish the combined pressure of rubber cylinder 10 and impression cylinder 30.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
