A kind of foam glue manufacturing device and foam glue manufacturing process

Abstract

The invention belongs to the technical field of foam glue, and discloses a foam glue manufacturing device, comprising a first mold assembly for cutting and forming a first foam assembly and a second mold assembly for cutting and forming a second foam assembly, The step-by-step processing of different molds simplifies the structure of the molds and avoids the problem of foam glue being stuck in the gap between the cutting knives that is easy to occur in one-time processing. The invention also discloses a foam glue manufacturing process, including: bonding and cutting the first base film, the first double-sided adhesive tape and the mesh to form the first foam component; combining the second base film with the second double-sided adhesive The surface adhesive is bonded and cut to form the second foam component; the second double-sided adhesive is bonded to the mesh, so that the first foam component and the second foam component are bonded together. The present invention can reduce the cutting thickness of the mold by dividing the foam glue into the first foam component and the second foam component, thereby avoiding the problem that the edge of the hole and the cutting edge are easily deformed.

Description

technical field [0001] The invention relates to the technical field of foam glue, in particular to a foam glue manufacturing device and a foam glue manufacturing process. Background technique [0002] Foam glue is made of foam as the base material, coated with solvent-based (or hot-melt) pressure-sensitive adhesive on one or both sides and then coated with release paper. It has the functions of sealing and shock absorption, and has excellent Compression deformation resistance, flame retardancy, wettability, etc., widely used in electronic and electrical products, mechanical parts, auto parts, etc. [0003] According to the different application fields of foam glue, there are certain requirements for its shape. Foam glue with a specific shape is generally processed by a mold at one time. Due to the limitation of processing cost and processing volume, the molds generally used are relatively simple and cost-effective. Low, the existing molds only have cutting molds with a cert...

Problems solved by technology

[0004] The purpose of the present invention is to provide a foam glue manufacturing device and a foam glue manufacturing process to solve the problem of foam glue being stuck in the gap between cutting knives after cutting in the prior art and processing thicker foam glue. When using cotton glue, the holes processed on the foam glue and the edges of the foam glue are prone to deformation
