现有技术中，对于PU、皮革的裁切主要是通过裁切机进行裁切，在裁切的时候是通过单层进行裁切的，因为PU、皮革材质较软，将其叠加在一起时，各层之间的间隙较大，会起到一种膨胀的效果，裁切机进行裁切时，效果不好。In the prior art, the cutting of PU and leather is mainly cut by a cutting machine.

By placing a knife template at the bottom and then using a vacuum cover to cover it, it uses a vacuum mode to compress each layer of material and then punch it. Processing, but this method requires preset knife molds, and a large number of knife molds need to be arranged. Although it can cut multiple layers at a time, the efficiency is still low, and because the material is placed in a closed mechanism, the cutting The effect cannot be seen from the outside until it is completed, and a large amount of material is cut at once. If something goes wrong, or the quality is not good, the waste is serious.

本发明的工作流程如下：The workflow of the present invention is as follows:
首先，进行上料，在上料端将多层布料(或者皮革、塑胶)堆叠在输送带13上，然后输送带传动，到达合适的位置，此时提升气缸推动真空罩下降，真空罩的侧板12卡入到Y向支撑密封块以及X向支撑密封块组成的回转槽内，此时真空罩的侧板12的密封条16与回转槽构成密封，然后在通过抽真空装置进行抽真空，抽真空时，侧板 12压缩下降，带动顶板也下降，此时顶板14上的堵块15也跟着下降，堵块15会拉着气缸6的活塞杆下移，如果下降距离长，则需要启动气缸6主动推动活塞杆下移，待抽完真空后，启动气缸6向下压，将多层压缩好的料子压着，然后启动提升气缸5，将真空罩提升上去，此时堵块15与真空罩顶板14分离，待真空罩提升到最顶部时，启动夹紧气缸8，将夹紧臂7压在多层料子上，然后气缸6带动堵块15上升，此时就完成了压缩料子的过程。First, carry out feeding, stack multiple layers of cloth (or leather, plastic) on the conveyor belt 13 at the feeding end, and then drive the conveyor belt to reach a suitable position. At this time, the lifting cylinder pushes the vacuum cover down, and the side of the vacuum cover The plate 12 is snapped into the rotary groove composed of the Y-direction support seal block and the X-direction support seal block. At this time, the sealing strip 16 of the side plate 12 of the vacuum cover forms a seal with the rotary groove, and then the vacuum is carried out by the vacuum device. When vacuuming, the side plate 12 is compressed and dropped, and the top plate is also lowered. At this time, the blocking block 15 on the top plate 14 also drops, and the blocking block 15 will pull the piston rod of the cylinder 6 to move down. If the drop distance is long, it needs to be started The cylinder 6 actively pushes the piston rod down. After the vacuum is drawn, the cylinder 6 is started to press down, pressing the multi-layer compressed material, and then the lifting cylinder 5 is started to lift the vacuum cover up. At this time, the block 15 and The top plate 14 of the vacuum cover is separated. When the vacuum cover is lifted to the top, the clamping cylinder 8 is started, and the clamping arm 7 is pressed against the multi-layer material, and then the cylinder 6 drives the blocking block 15 to rise. At this time, the compression of the material is completed process.
然后输送带13启动，带动多层料子向裁切端移动进行切割，在机架1上设置有一限位机构，当最前端的移动块2前端的触碰开关碰到限位机构时，该移动块上的夹紧臂会在夹紧气缸带动下松开，保证料子过去，然后后续的移动块相继触碰到前面的移动块。Then the conveyor belt 13 is started to drive the multi-layer material to the cutting end for cutting. A limit mechanism is provided on the frame 1, and when the touch switch at the front end of the moving block 2 at the front end touches the limit mechanism, the moving block The upper clamping arm will be released by the clamping cylinder to ensure that the material passes, and then the subsequent moving blocks successively touch the previous moving block.
本发明通过采用真空罩将多层待切割料进行抽真空压缩处理，能够将一次性放置多层待切料，可以将多层的待切料通过抽真空的形式进行压缩贴合，便于一次性进行多层料的裁切，提高了裁切效率；通过在顶板上设置多个放气孔，并在放气孔上设置堵块，堵块与气缸连接，可以在抽完真空后，启动气缸，将多层料子压着，此时既能够将真空罩内的气体排出，将真空罩恢复原位，并且通过提升机构将真空罩提起，再通过夹紧机构将多层料压紧，便于真空罩的退出；通过在移动块前端设置触碰开关控制夹紧臂的松开或者压紧，能够便于在裁切的时候随时将夹紧机构退出，保证在裁切之前保持多层料子的压缩状态，保证了裁切的效果。以上公开的本发明优选实施例只是用于帮助阐述本发明。优选实施例并没有详尽叙述所有的细节，也不限制该 发明仅为所述的具体实施方式。显然，根据本说明书的内容，可作很多的修改和变化。本说明书选取并具体描述这些实施例，是为了更好地解释本发明的原理和实际应用，从而使所属技术领域技术人员能很好地理解和利用本发明。本发明仅受权利要求书及其全部范围和等效物的限制。The invention adopts a vacuum hood to perform vacuum compression processing on multiple layers of materials to be cut, and can place multiple layers of materials to be cut at one time, and can compress and laminate the multiple layers of materials to be cut by vacuuming, which is convenient for one-off Multi-layer cutting is performed to improve the cutting efficiency; by providing multiple vent holes on the top plate and blocking blocks on the vent holes, the blocking block is connected to the cylinder, after the vacuum is exhausted, the cylinder can be started and the The multi-layer material is pressed, at this time, the gas in the vacuum hood can be discharged, the vacuum hood can be restored to the original position, and the vacuum hood is lifted by the lifting mechanism, and then the multi-layer material is compressed by the clamping mechanism, which is convenient for the vacuum hood.
