Three-in-one woven fabric coating system and method thereof

Abstract

The invention relates to a three-in-one woven fabric coating system and a method thereof. The system comprises a bottom plate, a fixed support, two guide roller groups, a charging barrel, a pressure pump, a glue feeding frame, a gluing head, a connecting rack, a uniform coating device, a combination frame and an electric winding column, wherein the fixed support is mounted at the right end of thebottom plate, the two guide roller groups are mounted at the left end and the right end of the fixed support, the charging barrel is mounted at the upper end of the fixed support and connected with aglue feeding frame through the pressure pump, the glue feeding frame is mounted on the fixed support, the connecting rack is mounted in the middle of the fixed support, the uniform coating device is mounted at the lower end of the connecting rack, the combination frame is mounted in the middle of the bottom plate, and the electric winding column is mounted at the left end of the bottom plate. According to the system and the method, the problems that glue is difficult to extrude out in the glue coating process when applied to woven fabric because of higher viscosity of a resin solution as wellas resin in a molten state has higher temperature and tends to solidification before dripping frequently due to longer conveying path during conveying can be solved.

Description

technical field [0001] The invention relates to the field of woven cloth coating, in particular to a three-in-one woven cloth coating system and method thereof. Background technique [0002] Woven cloth is made of polypropylene and polypropylene flat yarn as raw materials. It is composed of two sets of parallel yarns whose shape is flat. It can be made into a packaging bag. Among them, the three-in-one woven cloth is a kind of woven cloth. A woven fabric made by sandwiching the molten resin between the plastic film and the woven fabric after cooling. During the processing, the following problems are often encountered in the process of coating the woven fabric: [0003] 1. During the coating process, the resin solution is usually applied to the woven fabric with a coating roller. However, due to the high viscosity of the resin solution, when applying glue to the woven fabric, the glue is difficult to squeeze out, resulting in The amount of smearing on the surface varies, and...

AI Technical Summary

Problems solved by technology

[0003] 1. During the coating process, the resin solution is usually applied to the woven fabric with a coating roller. However, due to the high viscosity of the resin solution, when applying glue to the woven fabric, the glue is difficult to squeeze out, resulting in The amount of smearing on the surface varies, and when the plastic film and the woven cloth are pressed together in the later stage, the thickness of the resin layer often appears uneven;

[0004] 2. The temperature of the resin in the molten state is high. Due to the long transportation path during transportation, it often has a tendency to solidify before dripping, which often causes the ejection hole to be blocked in the long run
