Woven bag covering machine

Abstract

The invention belongs to the technical field of woven bag edge covering, and particularly relates to a woven bag covering machine. The woven bag covering machine comprises an covering machine body, aworkbench is arranged at the bottom of the covering machine body, the top of the covering machine body is connected with a presser foot plate through a round rod, a needle rod is connected to the covering machine body at one side of the round rod in a sliding mode, the needle rod is driven by a transmission device to do up-down reciprocating motion, and a sewing needle is fixedly connected to thebottom of the needle rod; and an extension plate is connected to a position, corresponding to the presser foot plate, of one side of the workbench, a hot melting plate is fixedly connected to the extension plate through a support, a pair of horn-shaped guide plates are arranged in front of the hot melting plate, one end, far away from the presser foot plate, of each guide plate is provided with afeeding port, the other end of each guide plate is provided with a discharging port, and the hot melting plate is connected with a power supply through a controller. According to the woven bag covering machine, the edge of a woven bag is subjected to hot melting through the hot melting plate, so that the thread generation of the edge of the woven bag is reduced, and the edge covering quality is improved.

Description

technical field [0001] The invention belongs to the technical field of woven bag hemming, in particular to a woven bag hemming machine. Background technique [0002] Woven bag, also known as snakeskin bag. It is a kind of plastic bag, used for packaging, and its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. [0003] The main production process of woven bags is to use plastic raw materials to extrude film, cut, and unidirectionally stretch them into flat yarns, weave through warp and weft into woven bags with open ends, and finally fold and sew the edges of the bottom edge to form For the finished woven bag, in order to avoid loosening of the warp and weft flat yarn at the sewing place of the woven bag and cause the sewing thread to be loose, the woven bag is hemmed. However, the existing hemming device performs hemming after hemming. The hemming strips are easy to separate from the woven bag, and the sewn hemming is ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, solve the problem that the sewing thread is loose due to the loosening of the warp and weft flat yarn at the sewing place of the woven bag in the prior art, and then the threading is generated. When the threading is too long, it is easy to cause entanglement and hinder the woven bag. Smooth crimping and feeding affect the hemming efficiency of the woven bag. At the same time, the woven bag is prone to wrinkles. When the folds enter the groove, the clamping column cuts the groove, which affects the continuous production of the hemming machine. A woven bag proposed by the present invention Hemming machine
