A kind of manufacturing process of plastic lined woven bag

Abstract

The invention relates to a manufacturing process of a plastic-lined woven bag. The plastic-lined woven bag manufacturing process adopts the following plastic-lined woven bag manufacturing device. The plastic-lined woven bag manufacturing device includes a supporting side plate, a guide roller, a conveying roller, Laminating mechanism and rolling mechanism; the laminating mechanism includes a laminating shaft, a rotating plate, a downward pressure spring, a downward pressure connecting plate, a connecting horizontal plate, a telescopic rod, a telescopic spring and a scraper; the above plastic lining is used to weave The manufacturing process of the plastic-lined woven bag by the bag making device includes the following steps: S1, placing the film roll; S2, conveying the film roll; S3, laminating the film roll; S4, rolling the film roll; S5, winding the woven plastic film . The present invention can solve the problems existing in laminating and rolling operation of the plastic-lined woven bag: the alignment cannot be performed when laminating the woven film and the plastic film, so that there is a certain deviation between the woven film and the plastic film, etc. .

Description

technical field [0001] The invention relates to the technical field of woven bag processing, in particular to a manufacturing process of a plastic-lined woven bag. Background technique [0002] Plastic-lined woven bags are packaging materials for moisture-proof goods. It is formed by pasting plastic film on the inner side of ordinary woven bags. Plastic-lined woven bags are widely used in food packaging and industrial product packaging. [0003] Plastic lined woven bags need to be mounted with plastic film in the woven film during processing. At present, when mounting the plastic film in the woven film, the two kinds of film rolls are first unrolled, and the inner surface is coated with The glue is connected together by laminating and rolling. The existing problems in laminating and rolling plastic-lined woven bags are as follows: [0004] 1. The alignment cannot be performed when the woven film and the plastic film are laminated, which makes it easy to have a certain devia...

AI Technical Summary

Problems solved by technology

[0004] 1. The alignment cannot be performed when the woven film and the plastic film are laminated, which makes it easy to have a certain deviation between the woven film and the plastic film, resulting in poor production effect of the woven bag, and the woven film and the plastic film will also appear wrinkled;

[0005] 2. When rolling between the woven film and the plastic film, the glue on the outside of the woven film and the plastic film will be transferred to the outer surface of the woven film and the plastic film through the rolling wheel, thus affecting the winding of the woven plastic film
