Composite plastic woven bag production bag making equipment and bag making process

Abstract

The invention relates to bag manufacturing equipment and a bag manufacturing process for composite plastic woven bag production. The production work of composite plastic woven bags is completed through cooperation of a bottom plate, side plates, a feeding device, a lifting device and a flattening device. According to the composite plastic woven bag production bag-making equipment and the bag-making process, the problems that rolled woven bags are loose during feeding due to the fact that existing equipment generally and directly feeds the rolled woven bags and do not clamp the rolled woven bags, and the rolled woven bags are not provided with a limiting mechanism after being fed, so that the production efficiency of the rolled woven bags is greatly improved can be solved. The problems that in the prior art, due to the fact that the woven bags are wound, the wound woven bags are rewound, and consequently repeated feeding is caused are solved, and the problems that existing equipment usually and directly conducts cutting and sewing treatment on the fed woven bags and does not conduct flattening treatment on the woven bags before cutting and sewing, and consequently the cut and sewn woven bags are wrinkled and folded are solved.

Description

technical field [0001] The invention relates to the technical field of woven bags, in particular to a bag-making equipment and a bag-making process for the production of composite plastic woven bags. Background technique [0002] Using polypropylene and polyethylene resin as raw materials, extruded and stretched into flat filaments, and then woven into plastic woven fabrics are called substrates, and they are made by casting method for packaging powder or granular solids. Materials and flexible items are called composite plastic woven bags. Composite plastic woven bags include two-in-one bags made of cloth and film and three-in-one bags made of cloth, film and paper. The outer layer of the three-in-one bag is made of refined white kraft paper or yellow kraft paper, and the inner layer is made of plastic woven cloth. The plastic particles PP are melted by high temperature and high pressure, and the kraft paper and the plastic woven cloth are compounded together, and an inner ...

AI Technical Summary

Problems solved by technology

[0004] (1) The existing composite plastic woven bag production equipment generally directly loads the roll woven bag without clamping the roll woven bag, which leads to the roll woven bag being loose during feeding, and the roll woven bag There is no limit mechanism after feeding, resulting in the rewinding of the roll of woven bags, resulting in repeated feeding

[0005] (2) The existing composite plastic woven bag production equipment usually directly cuts and sews the woven bag after feeding, and does not flatten the woven bag before cutting and sewing, resulting in the woven bag after cutting and sewing When wrinkles and folds occur
