Circulating wiring die cutting process

Abstract

The invention relates to a circulating wiring die cutting process. A product with a double-face structure and a shape is molded through die cutting at one time; an adopted die cutting knife group comprises a first circular knife roll, a bottom roll and a second circular knife roll which fit each other; raw materials are correspondingly bonded on the two faces of a double side adhesive tape in twolayers to form a main material strip; a first protective film and a second protective film are correspondingly bonded on the surfaces of the two layers of raw materials; the main material strip penetrates through a first circular knife mold and the bottom roll; the first circular knife roll and the bottom roll are matched with each other to simultaneously carry out die cutting on the first protective film and the raw materials in the upper layer; by using one group of winding rolls, the first protective film and waste materials are wound and separated from the raw materials in the lower layer;the separated raw materials in the lower layer and the second protective film penetrate through the space between a second circular knife mold and the bottom roll after turning back for 180 degrees;die cutting is carried out on the raw materials in the lower layer and the second protective film; and by using the other group of winding rolls, the second protective film and the waste materials arewound. The die cutting accuracy of the double-face product is greatly improved, and the die cutting efficiency of the double-face product is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of die-cutting, in particular to a circulating wire die-cutting process. Background technique [0002] Die-cutting process refers to the process of cutting tape or other plate blanks into required shapes or cut marks under pressure by using die-cutting knives and crimping knives; when producing products with double-layer machine structure, usually It is necessary to die-cut the material strips separately, and then assemble the processed raw materials into a whole. The die-cutting efficiency of this method is low, and the structure and size of each layer of the product of the double-layer structure are different, and often need to be processed After completing one layer of raw materials, it is time-consuming and laborious to replace the die-cutting plate, and the efficiency is low; and because there are errors in parameters such as tension during the two-time belt operation, the two-layer structure of the pro...
