Blanking and taking method of webs after automatic transverse cutting and die cutting

Abstract

The invention discloses a blanking and taking method of webs after automatic transverse cutting and die cutting and relates to the blanking and taking method in a full-automatic web platen transverse cutting and die cutting machine. The method comprises the steps of utilizing a pressing part in motion to press materials which are well transversely cut or die-cut on a support part and driving the materials and the support part to move together, thereby pulling apart the materials which are well transversely cut or die-cut. Compared with the thrust method of the prior art, the pulling-apart method does not need to change a tooling no matter how the shape of a fracture of a product changes, thereby greatly reducing the cost and improving the efficiency; and the taking adopts the method of drawing from the back of a hopper, compared with the taking method from the front in the prior art, the drawing method can greatly reduce the tension degree of workers and avoid the confusion caused by non-rapid taking.

Description

Technical field [0001] The invention relates to a method for cutting and retrieving material from a fully automatic cross-cutting die-cutting machine for flattening and flattening roll material. Background technique [0002] At present, there are two types of automatic cross-cutting die-cutting machines for roll materials, horizontal and vertical. Since the flat-pressing and cross-cutting die-cutting method belongs to the indentation method, it is difficult to ensure that the die-cutting machine can be used in mass production. The middle cut marks are always completely cut off. In addition, in the automatic cross-cut die-cutting of the roll material, sometimes in order to ensure that the cut material can be sent out smoothly, it is also necessary to make some small connections. For this reason, a mechanism must be used to completely cut it. Open it and fold it up so that workers can easily take it away. The material breaking method used in the market is described in the app...

Problems solved by technology

[0006] 1 When producing products with different fracture shapes, it is necessary to make different blanking plates. This not only increases the cost, but also requires labor and labor to assemble, disassemble and debug the blanking plates

[0007] 2. If the blanking plate production is too precise, the blanking gap is too small, not only the cost is too high, but also the material that has been cross-cut or die-cut is easy to be damaged when the feeding position is not accurate enough. If the precision is too low, the blanking gap is too large and it is easy to cause breakage. Incomplete materials, especially in low-speed production or adjustment, it is easy to fail to break

[0008] 3 Since the blanking plate is reciprocating, it must wait for its return before the next feeding can be carried out, which greatly affects the production efficiency

[0009] 4 The existing way of retrieving materials is that workers stand on the front of the hopper and take out the finished product from the front of the hopper. Since the speed of cross-cutting and die-cutting is very high now, the number of operations per minute is generally more than 90 times, so the workers must reclaim the materials. Quite quickly, otherwise the succession of finished products will cause confusion
