Description

Technical Field

[0001] The invention relates to a continuous loading and unloading system for die-cutting equipment. Background Art

[0002] Die-cutting equipment is a kind of equipment that uses molds to apply pressure to materials for cutting, creasing, hot stamping and other processes. It is widely used in post-processing in industries such as printing and packaging, electronics, and mobile phone rubber pads.

[0003] The original roll-to-roll circular knife die-cutting process or hydrogen energy MEA packaging process adopts roll-to-roll material shaft unwinding. A lot of materials are used. The basic unwinding layout is up and down and on both sides (unwinding material shaft), parallel to the die-cutting knife seat, for compounding and die-cutting of multi-layer materials. When the roll material put into the material shaft is used up, it is necessary to manually stop the equipment and enter the equipment to replace the roll material, and manually tape the head and tail of the new and old roll materials to complete the material replacement action. Because the process and equipment require a large number of roll materials, as long as there is a roll of material to be replaced, it is necessary to stop the machine for manual processing, which greatly affects the utilization rate of the equipment, and manual operations are required (manually handle the head and tail of the new and old materials. Tape sticking) Manual processing of new and old materials (tape splicing) has great differences in experience and processing effects, which will also cause the material to enter the die-cutting knife seat. There will also be a distance of defects (front and back joints of new and old materials, misalignment, wrinkles, etc.), so it will also affect the product yield rate.

[0004] It can be seen that the existing die-cutting equipment has the following problems: 1. The material strip unwinding adopts an up-and-down layout, and the material cannot be fed and unloaded from the lateral side of the die-cutting equipment. It is constrained by the space of the production line and poses a safety hazard to the operator. 2. After the material roll is used up, it needs to be shut down and manually replaced, which affects the equipment utilization rate and has high requirements for the operator's experience. After the material is replaced, there will be a distance of defects. 3. The waste strip after the material is discharged is often tangled into a ball, which brings difficulties to subsequent processing. Summary of the invention
