Manufacturing method of composite plastic woven bag

Abstract

The invention discloses a manufacturing method of a composite plastic woven bag, the manufacturing method of the composite plastic woven bag is realized by adopting the following composite treatment box, the method comprises the following steps: S1, woven bag gray cloth is conveyed to a position between two composite rollers through a conveying roller, and a composite film is conveyed to a position between the two composite rollers through the conveying roller; s2, the composite film and the woven bag gray cloth are extruded and composited through a composite roller to form a whole; s3, a cooling assembly is used for supplying air to a cooling box and a conveying table, so that the bonded woven bag gray cloth is rapidly cooled; s4, the bonded woven bag gray cloth is cut off through vertical displacement of a cutting knife; and S5, the woven bag gray cloth is conveyed through the conveying belt. According to the composite treatment box, the cutting knife and the composite roller are arranged together, after the composite roller is heated, a composite film and woven bag gray cloth are fused into a whole, and the composite woven bag gray cloth is rapidly cooled through the cooling assembly, so that cutting is facilitated, equipment from composite to cutting is reduced, and time is saved.

Description

technical field [0001] The invention relates to the technical field of woven bag making, in particular to a method for making a composite plastic woven bag. Background technique [0002] The composite plastic woven bag is made of polypropylene and polyethylene resin as raw materials, extruded and stretched into flat filaments, and then woven into a plastic woven fabric as the base material. The bag roll can be folded and cut into a woven bag, and finally formed into a finished woven bag by sewing or gluing. The composite plastic woven bag is used to pack powder and granular solid materials. [0003] At present, in the process of composite molding of functional film and woven bag body in the production of woven bags, most of them are completed by adhesion equipment, and the molding of woven bags needs to be completed by cutting equipment. In the process from composite molding to cutting, woven bags need to go through more The conveying roller conveys, resulting in a long tim...

AI Technical Summary

Problems solved by technology

[0003] At present, in the production of woven bags, the process of compounding functional films and woven bag bodies is mostly completed by adhesion equipment, while the forming of woven bags requires cutting equipment. In the process from composite molding to cutting, woven bags need to go through more Conveyor roller conveying, resulting in a long time between bonding and cutting and forming, passing through a lot of equipment

[0004] The effect of fast and efficient production cannot be achieved, for this reason, the present invention proposes a kind of manufacturing method of composite plastic woven bag on the basis of novel production equipment
