AI Technical Summary

Technical Problem

The existing horn foam dustproof net has complex preparation technology, high labor costs, low production efficiency, and is difficult to control the splicing, resulting in a decrease in the precision and quality of the finished product.

Method used

By combining the foam and the first adhesive layer with the base film, a first-level composite layer is formed, and then multiple layers are cut and simultaneously cut, then composite and cut holes with the mesh and the second adhesive layer, and finally cutting edges and cutting tapes through the cutting knife, simplifying the process and improving processing accuracy.

Benefits of technology

It realizes high-precision hole opening and molding of the horn foam dustproof mesh, simplifies the production process, reduces labor costs, improves production efficiency and finished product quality, and is suitable for industrial production.

Abstract

The invention relates to the field of horn dust screen processing, and discloses a horn foam dust screen and a preparation method thereof.The preparation process comprises the following steps that a first bottom supporting film, foam and a first adhesive layer are provided, and the first bottom supporting film, the foam and the first adhesive layer are fed to a first composite roller to obtain a first-stage composite layer; performing hole cutting operation on the first-stage composite layer through a first cutter to form a first sound outlet hole; providing a second adhesive layer, and performing hole cutting operation on the second adhesive layer through a second cutter to form a second sound outlet hole; providing a gauze, and feeding the primary composite layer, the gauze and a second adhesive layer to a second composite roller to obtain a secondary composite layer; the second-stage composite layer is punched through a third cutter, and a pre-horn foam dust screen is obtained; and the horn foam dustproof net is cut off through a fourth cutter, and the horn foam dustproof net is obtained. And synchronous feeding is achieved through the automatic feeding device, manual alignment is avoided, the trepanning precision is high, the preparation technology is simple, and machining forming is easy.
