Making process of plastic lining woven bag

Abstract

The invention relates to a making process of a plastic lining woven bag. The making process of the plastic lining woven bag adopts the following plastic lining woven bag making device. The plastic lining woven bag making device comprises a supporting side plate, a guide roller, a conveying roller, a laminating mechanism and a rolling mechanism; and the laminating mechanism comprises a laminating rotating shaft, a rotating plate, a lower pressing spring, a lower pressing connecting plate, a connecting transverse plate, a telescopic rod, a telescopic spring and a scraping plate. The making process of the plastic lining woven bag adopts the plastic lining woven bag making device and comprises the following steps of S1 film roll placement, S2 film roll conveying, S3 film roll bonding, S4 filmroll rolling and S5 winding of a woven plastic film. According to the making process, the problems that when an existing plastic lining woven bag is subjected to attaching rolling operation, alignmentcannot be carried out when the woven film and the plastic film are attached, and a certain deviation is prone to exist between the woven film and the plastic film are solved.

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. When the woven film and the plastic film are laminated, the alignment cannot be performed, so that there is a certain deviation betwe...

AI Technical Summary

Problems solved by technology

[0004] 1. When the woven film and the plastic film are laminated, the alignment cannot be performed, so that there is 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, thereby affecting the winding of the woven plastic film
