Making method of composite plastic woven bag

Abstract

The invention relates to a making method of a composite plastic woven bag. Gluing and winding equipment is used in the making method, and comprises a base, a double-sided gluing device, a winding device, an operating platform, a supporting device and an extrusion adjusting device. When a gluing arc-shaped plate moves downwards, a glue overflowing plate is driven to be pressed downwards through a sliding rod, and an outer bag at the lower part of a gluing roller is sufficiently smeared with glue while the sliding rod of the gluing arc-shaped plate drives the glue overflowing plate to be pressed downwards, so that double-sided gluing on an inner bag and the outer bag of the woven bag is realized; a winding motor is started, so that the winding roller is driven to rotate for winding; during adjustment of the tightness of the inner bag and the outer bag before winding operation, a loosening and tightening rod rotates to drive a loosening and tightening roller to rotate, so that the tightness of the inner bag and the outer bag clamped in the loosening and tightening roller can be adjusted, and the sticking effect is better; and the glue adhered to the inner bag and the outer bag is effectively extruded through an extrusion roller, so that the inner bag and the outer bag are smoother after being adhered, redundant glue is extruded out, and the glue is recycled.

Description

technical field [0001] The invention relates to the technical field of making woven bags, in particular to a method for making a composite plastic woven bag. Background technique [0002] Woven bag, also known as snakeskin bag. It is a kind of plastic bag, which is used for packaging. Its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene, and composite woven bags are common; [0003] Composite woven bags are divided into two-in-one, three-in-one, etc. Composite plastic woven bags are made by compounding or coating woven cloth with compounding material and paper or film to obtain a tube or piece of cloth. The tube can be cut, Print, sew, and make ordinary seamed bottom bags, or punch, fold, cut, print, and sew to make cement bags, and the obtained pieces of cloth can be bonded, printed, cut, and bottomed to make Paste bottom bags can also be welded and coiled to make tarpaulins, geotextiles, and the most important step in ...

AI Technical Summary

Problems solved by technology

[0005] (1) Since most of the woven bags are pasted in two layers, it is necessary to paste the final two layers, and the existing device cannot synchronize the double-sided glue on the surface that does not need to be pasted, so the pasting effect is poor;

[0006] (2) When the pasted two-layer bag cloth is rolled, the tightness of the roll cannot be adjusted, so the roll effect is poor;

[0007] (3) Before the glued bag is rolled up, the surface of the woven bag bonded by two layers of glue cannot be guaranteed to be smooth, and the excess glue cannot be squeezed and collected
