Manufacturing process of two-in-one composite plastic woven cloth

Abstract

The invention provides a manufacturing process of two-in-one composite plastic woven cloth, wherein a portal frame, a motor, a coating roller, an annular sliding chute, discharging devices, swing devices and a heat conduction cylinder are matched to complete operation. In the existing coating process, in general, a resin solution is directly poured onto the woven cloth, coating is carried out through the coating roller, and due to the fact that the concentration of the resin solution is high, it is difficult for the resin solution to drip, the single pouring amount of the resin solution is always unequal, and the pouring amount cannot be effectively controlled; and the temperature of the resin solution in hot melting state is higher, the phenomenon of cooling and solidification often occurs when the resin solution to be poured out is cooled, and when the resin solution is poured onto the woven cloth, the amount of the resin solution at each position of the woven cloth is unequal, and consequently the thickness of each position of a rolling layer of the woven cloth is uneven during rolling of the coating roller, With the manufacturing process of the two-in-one composite plastic woven cloth, the above problems can be solved.

Description

technical field [0001] The invention relates to the field of woven cloth production, in particular to a two-in-one composite plastic woven cloth production process. Background technique [0002] According to the main material, plastic woven bags are composed of polypropylene bags and polyethylene bags. According to the sewing method, they are divided into seamed bottom bags and seamed bottom bags. At present, they are widely used as a packaging material for fertilizers, chemical products and other items. Its main production The process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch them into flat wires, and then weave warp and weft products to obtain products, which are generally called woven bags. Among them, the two-in-one composite plastic woven bag is a kind of woven bag. When processing two-in-one composite plastic woven bags, it is necessary to coat the hot-melt resin on the woven cloth for cooling and molding. The following problems...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a two-in-one composite plastic woven cloth manufacturing process, which can solve the problem of pouring the resin solution directly onto the woven cloth in the existing coating process, and then coating it with an applicator roller. , due to the high concentration of the resin solution, it is difficult to drip, so the single pouring amount of the resin solution is often not equal, the pouring amount cannot be effectively controlled, and the temperature of the resin solution in the hot melt state is relatively high. When it is often cold, it will cool and solidify. When the resin solution is poured on the woven fabric, the amount of resin solution in each position of the woven fabric will vary, so that when the applicator rolls, the rolling of each position of the woven fabric will occur. Problems such as uneven layer thickness
