Edge cutting equipment for glass fiber cloth production and edge cutting process thereof

Abstract

The invention belongs to the technical field of glass fiber cloth production, particularly relates to edge cutting equipment for glass fiber cloth production and an edge cutting process thereof, and provides the following scheme that the edge cutting equipment comprises a workbench and an edge cutter, supporting frames are fixedly connected to the outer walls of the two sides of the workbench, and fixing plates are fixedly connected to the outer walls of the opposite sides of the two supporting frames; the outer walls of the opposite sides of the two fixing plates are fixedly connected with two third connecting shafts and two second connecting shafts through bearings. By arranging the secondary edge cutting assembly, after edge cutting operation is conducted on glass fiber cloth through an edge cutter, the strength of the glass fiber cloth is high, and burrs still exist after single-time edge cutting, at the moment, a second air cylinder is adjusted to drive a sliding block to slide in a guide rail, so that the glass fiber cloth is subjected to edge cutting operation; therefore, the secondary trimming cutter is driven to perform secondary trimming operation on the trimming position of the glass fiber cloth, complete cutting of the trimming position of the glass fiber cloth is ensured, and the trimming effect of the glass fiber cloth is further improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber cloth production, in particular to an edge trimming device for glass fiber cloth production and an edge trimming process. Background technique [0002] Fiberglass grid cloth is untwisted roving plain weave fabric, which is an important base material for hand lay-up FRP; the strength of the grid cloth is mainly in the warp and weft directions of the fabric. Directional cloth, it can arrange more rovings in the warp or weft direction, single warp direction cloth, single weft direction cloth; roving roving is made of parallel strands or parallel single filaments; According to the glass composition, it can be divided into: E-GLASS non-alkali glass roving and C-GLASS medium alkali glass roving.

AI Technical Summary

Problems solved by technology

[0003] When the existing glass fiber cloth is trimmed, the corners of the glass fiber cloth are generally cut by a trimming knife. During the pressing process of the trimming knife, the corners are cut off by extrusion. During the process, it is easy to cause bifurcations at the cutting points of the original filaments on the glass fiber cloth. The generation of the bifurcations will cause burrs to appear again at the corners of the cut edges of the glass fiber cloth after a short period of use, reducing the The use value of glass fiber cloth leads to the lack of use value of the edge trimming equipment for the production of glass fiber cloth
