Description

The present invention relates to the apparatus for cutting sheet material of flexible fabric, be applicable to the cut-out of fabric, be specially adapted to cut off the flexible fabric or cuff, collar, the bottom of clothing, and be used in the rubberizing fabric on other class clothing desired area, soft felt or some flexible fabric etc. in addition.

In traditional flexible fabric shearing device, when especially being used for fabric, having had and utilized cutting knife to cut merely apparatus for cutting sheet material by the fabric of roller supporting by short width of cloth cutting.

But, in the fabric shearing device that formerly has, that is, making and will prop up the fabric that is held on the roller through feeding roller and send, fabric just can cause fold in the process that arrives at the reception body of determining size through propelling movement; And if stretch on one side by the front end that this fabric in the clamping on one side of the roller of other setting, because the soft character of fabric itself finally will be elongated, if cut off according to such state, then the size that the fabric of Qie Duaning extended will be shunk and do not reached the size of regulation, so that produce deviation dimensionally in the fabric that cuts off, become substandard products, constituted and shortcoming such as can not have been sold as goods.

The present invention's purpose promptly is to eliminate above-mentioned shortcoming.

Here it is, a kind of apparatus for cutting sheet material of flexible fabric is provided, can not shorten under the not elongation condition, size is cut off fabric in accordance with regulations, particularly cut off the flexible fabric or cuff, collar, the bottom of clothing, and be used on other class clothing desired area rubberizing fabric etc., substandard products can be prevented to produce and the certain goods of size can be produced expeditiously.

The feature of the thin slice material cutter sweep of flexible fabric of the present invention is as follows: be provided with feeding roller 2 and be provided with top movable up and down cutting knife 9 and bottom cutting knife 3 in these feeding roller 2 the place aheads on board 1, pass through in the path therebetween at the flexible thin sheet stock of sending into 8, be provided with the fumarole that upwards sprays gas 5 that thin slice material 8 has been floated, and on this fumarole 5, then be installed with and do not make the floated top receiving plate 6 of necessary height of thin slice material 8 every appropriate gap, the thin slice of sending into for feeding roller 8 the gas by fumarole 5 ejections carry floating in, deliver between the top cutting knife 9 and bottom cutting knife 3 in the place ahead, square before in this top cutting knife 9 and bottom cutting knife 3, being equipped with on board 1 can be by the reception body 7 of certain size adjustment, when thin slice material 8 arrives this reception body 7, because this top cutting knife 9 and bottom cutting knife 3 misfit and with 8 cut-outs of thin slice material mutually, and at the same time, have the thin slice material 8 that this has cut off in one's care by setting the receiving plate 11 that the side also can freely advance and retreat under reception body 7.

In the present invention, for example can be without the mode of cramping by the roller 13 that a collection of spicule is installed, with the scalable flexible fabric of rubberizing is that thin slice material 8 is carried (also available sagging or other transport replace the roller 13 that spicule is installed), in course of conveying, the thin slice material of sending via roller 28 is above by fumarole 5 time, sprayed the influence of gas and floats.Then, the thin slice material 8 of come-up contacts with top receiving plate 6, between top cutting knife 9 and bottom cutting knife 3, the front end of this thin slice material is used on butt in the reception body 7 of standard certain size, be in to carry to hold being located at and receive on the receiving plate 11 that body can freely advance and retreat for 7 times, when top cutting knife 9 is fallen, just this thin slice material 8 being pressed certain size cuts off, be right after after the cut-out, receiving plate 11 retreats at once, and the thin slice material 8 of size cut-out promptly is piled up on the ribbon conveyer 12 in accordance with regulations, moves to removing direction.

Top cutting knife 9 guides it to move up and down by the groove 30 that is located on the board 1.In addition, receiving plate 11 by one up can before and after the effect of bar 16 of activity, when the latter's upper end rocks back and forth, this receiving plate about 11 is advanced and retreat.The waving of the up and down and bar 16 of cutting knife 9 on addressing can be undertaken by the motion of the eccentric cam 18 of eccentric shaft 15 and trough of belt.Such motion then can be by power source 14(motor for example) integrally drive.

Accompanying drawing according to the present invention below is elaborated to embodiment.

The present invention is provided with and is used for the thin slice material is transported to a pair of feeding roller 2 in the place ahead in board 1, is provided with the roller 13 that spicule has been installed simultaneously, is used for preventing that thin slice material 8 from sliding on feeding roller 2 and feed simultaneously.Remove this, in the place ahead of feeding roller 2, be equipped with and be used for bottom cutting knife 3 is assemblied in the bottom cutter supporter 4 of its front end, the surface then has a collection of fumarole 5 above this bottom cutter supporter 4 interior, and a top receiving plate 6 is placed latter top.The inside of this bottom cutter supporter 4 is the cavity form, promptly is introduced into the inner chamber of bottom cutter supporter 4 via gas pipeline 31 from the compressed air of compressor 10, and this inner chamber further becomes the mechanism through fumarole 5 ejection air again.In addition, be provided with elongated hole 32 and screw 26 in the place ahead of bottom cutting knife 3, can regulate the front position of the adjusting rod 33 of having set length, and can will receive the front end that body is assembled to adjusting rod 33, determine the front position of thin slice material 8 by them.Receive the square receiving plate 11 that is provided with under the body at this, this receiving plate 11 is got such structure, it be bearing in front end touch closing the thin slice material 8 that receives body 7 below, after thin slice material 8 cuts off, can be by this rearward retreating of receiving plate 11 thin slice material 8 be fallen to being put into the below.The below of this receiving plate 11 is the front position that is located at the ribbon conveyer 12 of board 1 outside, and this conveyer will be transported to wrapping position by the thin slice material 8 that certain size cuts off, and be packed under folded Duo state.

Fig. 1 and Fig. 4 show an example of the travelling mechanism of bright top cutting knife 9 and receiving plate 11, this top cutting knife 9, be delivered to the effect of the axial region 17 of top cutting knife 9 by motor one class power source 14 by eccentric shaft 15, bar 16, this top cutting knife be directed in the groove 30 and up and down.11 of receiving plates pass through the motion of the roller in the groove of the eccentric cam 18 of trough of belt, via linkage 20, working beam 21 is seesawed, allow and be arranged at lug 23(Fig. 3 on the receiving plate 11), activity plugs together in the elongated hole 22 of this working beam, makes seesawing of working beam 21 be converted to the advance and retreat motion of receiving plate 11.

As for the structure of ribbon conveyer 12, for example desirablely make the upper fuselage that the defeated formula machine 12 of belt is housed to carry out up parallel mobile form with jockey 24.This kind jockey 24, for example the available hydraulic cylinder makes it to move up and down and locate.

Among Fig. 1 27 is a cramp bar, slidably plugs together on the guide way 28 that is installed in the receiving plate 11, and it is mobile to be used for making receiving plate 11 to advance and retreat; And 29 be a tensioning shaft, is used for making thin slice material on the roller 13 that is fed to the band spicule to stretch tight and stretchs out.

Because therefore above-mentioned the sort of structure among the present invention can be supplied in feeding roller 2 to the thin slice material 8 of flexibility via the roller 13 of being with spicule, is limited to by preliminary dimension this thin slice material 8 is sent.Then, when this thin slice material 8 carried by feeding roller bottom cutoff knife rack 4 above the time, though can float,, just can prevent fold above this fumarole 5 owing to top receiving plate 6 is arranged because of the gas that is arranged at fumarole 5 ejection in the bottom knife rest 4.The thin slice material 8 of Shu Songing in this way arrives when receiving body 7 by the bottom cutting knife at its front end, and the top cutting knife promptly descends and thin slice material 8 is cut off.Timing means when descending as for top cutting knife 9 when the power source 14 of feeding roller 2 and top cutting knife 9 is used as common power, is to wait the device of regulating the speed by gear mechanism.In addition, when adopting miscellaneous equipment, then can consider such mechanism: use up, static surveys the thin slice material 8 and the moment that receives body 7 butts with the various sensors of contact, make power source 14 revolutions and the top cutting knife is turned round as power source.

Then, when being cut off by the top cutting knife or after cutting off, receiving plate 11 is shifted to the rear, the thin slice material 8 after cutting off is promptly fallen the below from receiving plate 11, and simultaneously overlaps onto in turn on the ribbon conveyer 12 that is positioned at the below, and one side falls.At this moment, pile the thickness through the thin slice material of cut-out of Duo above ribbon conveyer 12 successively and increase progressively, and can contact, because the effect of hydraulic cylinder 25 reduces the height of ribbon conveyer 12 with the lower surface of receiving plate 11.The Height Adjustment work of this ribbon conveyer 12 is preferably corresponding with breaks.After the thin slice material of some has been cut off, start ribbon conveyer 12, prick these goods that cut off of packing with rope.

When the width of needs change thin slice material 8, can become flexible screw 26, adjust adjusting rod 33 along elongated hole 32, after having determined institute's sizing, again with this screw-driving, each operation of being carried out is promptly with aforesaid identical subsequently allowing reception body 7 reach desirable position.But, be necessary to adjust the timing relationship that cuts off by the top cutting knife.So,,, just should before thin slice material 8 arrives reception body 8, cut off if cut off according to the timing before enlarging in order to enlarge the width of cut-out.In addition, if at first light, static, the various sensors of contact mechanically being combined as detection agency (for example is assembled to this class sensor and receives on the body 7, control power source in view of the above), when being used for carrying out timing and adjusting, just can make adjustment sometimes and save the amount of labour.

As mentioned above,, become inhomogenous fabric with the goods that cause severing, particularly when the cut-out of lacking width, can in fabric, not produce fold for taking place to stretch because of flexibility according to the present invention; Perhaps when cutting off the rubberizing fabric, because it is unnecessary with structures such as fabric front end stretchings, so need not consider the extensibility of rubber, still can be as usually, utilization is from the gas of fumarole ejection, easily cut off according to certain length by set cutting knife, the goods after cutting off do not have deviation, do not need the raw material of fabric are cut off by surplus yet.Thereby can reduce manufacturing cost.In addition, also be easy to change the width of thin slice material by the position of change reception body 7, also because the thin slice material through cutting off is to carry, pack in the mode of heap Duo on ribbon conveyer, also just be easy to the thin slice material of this kind cut-out is carried out the processing of next procedure, have simple in structurely simultaneously, can organize advantages such as large-scale production at an easy rate.
