A double-sided adhesive asynchronous die-cutting material-saving equipment

Abstract

The invention discloses double-sided adhesive tape asynchronous die cutting saving equipment. According to the double-sided adhesive tape asynchronous die cutting saving equipment, to-be-saved materials are repasted to a main material belt from the upper surface through an asynchronous method, the repasting step can be subjected to personalized adjustment according to the actual requirements, anda waste area in the middle is saved; an auxiliary indentation assembly is arranged on the front side, near an asynchronous feeding coil, of an asynchronous repasting knife, the auxiliary indentation assembly is responsible for indentation treatment of a to-be-repasted repasting material belt, the auxiliary indentation assembly makes marks of the to-be-repasted repasting material belt protrude upwards, and an asynchronous cutting knife cuts the upward protruding marks from top to bottom; through an up and down way, concave knife prints produced by die cutting can be effectively decreased, and the precision and quality of die cutting are improved; and a way of synchronous driving of indentation and die cutting is adopted, the accuracy can be improved, the pressure magnitude of indentation can be adjusted, the condition of reverse knife prints caused by excessive indentation is effectively avoided, the quality is ensured, and waste is lowered.

Description

technical field [0001] The invention relates to the technical field of double-sided adhesive asynchronous cutting, in particular to a double-sided adhesive asynchronous die-cutting and material-saving equipment. Background technique [0002] At present, with the development of electronic products, especially the smart phone market, the requirements for die-cutting processing are becoming more and more stringent. During die-cutting processing, it is generally necessary to transfer the double-sided tape to the main material tape for subsequent processing. According to the material belt, because the effective use area of ​​raw materials is too small, the utilization rate of the whole roll of materials is too low and the material is wasted. Therefore, in order to save materials, the materials that need to be saved are transferred from above to the main material belt through an asynchronous method. , the repost step can be adjusted individually according to actual needs, so as to...

[0002] At present, with the development of electronic products, especially the smart phone market, the requirements for die-cutting processing are becoming more and more stringent. During die-cutting processing, it is generally necessary to transfer the double-sided tape to the main material tape for subsequent processing. According to the material belt, because the effective use area of ​​raw materials is too small, the utilization rate of the whole roll of materials is too low and the material is wasted. Therefore, in order to save materials, the materials that need to be saved are transferred from above to the main material belt through an asynchronous method. , the transfer step can be adjusted according to actual needs, so as to save the waste area in the middle, that is, the way of asynchronous die-cutting

The structure of the current asynchronous die-cutting method is generally relatively simple. After die-cutting, the die-cutting position of the rubber surface is prone to produce large knife marks, and the die-cutting force is difficult to adjust, which not only affects the product quality, but also may lead to waste of product materials. , which seriously affects the cost of processing raw materials
