Manufacturing method of composite plastic woven bag

Abstract

The invention relates to a manufacturing method of a composite plastic woven bag. A composite plastic woven bag manufacturing device adopted in the method comprises a bottom plate, a conveying chain plate, a bearing table, a rotating mechanism and a leveling mechanism; the rotating mechanism comprises a rotating motor, a rotating connecting rod, a rotating shaft, a rotating turning plate, a fixedsucker, an air pump, a supporting ring and a supporting plate. The manufacturing method comprises the following steps: S1, unwinding a woven bag roll; S2, conveying the woven bag; S3, overturning thewoven bag; S4, pressing the woven bag; and S5, collecting the woven bag. The problems that in the prior art, size offset is likely to occur when the woven bag is manually folded, the woven bag is folded in half in a staggered mode, and the folded woven bag is prone to wrinkling when the woven bag is folded can be solved.

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to a method for making a composite plastic woven bag. Background technique [0002] Composite plastic woven bag is made of polypropylene and polyethylene resin as raw materials, which are extruded and stretched into flat wires, and then woven into plastic woven cloth as the base material. The bag roll can be made into a woven bag after being folded and cut, and finally the finished woven bag is formed by sewing or bonding. The composite plastic woven bag is used for packing powdery and granular solid materials. [0003] Folding and cutting of composite plastic woven bags in ordinary factories is generally carried out manually. First, the woven bag is folded into a certain size manually, and then the woven bag is folded in half, and then the folded woven bag is placed in a suitable position. Cutting, the existing problems when turning over the woven bag are as follows: ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the woven bag is manually folded, it is prone to size deviation, which leads to the phenomenon of misalignment of the woven bag, and the folded woven bag is prone to wrinkles;

[0005] 2. The woven bag is prone to skewing when crimping, and the flattening and cutting of the woven bag cannot be carried out synchronously, resulting in a certain error in the size of the woven bag
