Gluing device for plastic lined woven bag

Abstract

The invention relates to a gluing device for a plastic lined woven bag. The gluing device comprises a bottom plate, unwinding rollers, unwinding supporting plates, a gluing roller, a rotating motor, gluing supporting plates and a gluing mechanism, wherein two unwinding rollers are uniformly distributed vertically above the right end of the bottom plate, and the front and rear ends of the unwindingrollers are both installed on the top of the right end of the bottom plate by the unwinding supporting plates respectively; the gluing roller is positioned on the left side between the two unwindingrollers, and the gluing supporting plates are distributed on the front and rear sides of the gluing roller respectively; the gluing mechanism comprises a gluing cross plate, a glue tank, a nozzle, a pressurizing pump, connecting brackets, scraping supporting plates, a scraping frame and guide rollers. The problems that when woven films or plastic films are glued in the prior art, the woven films or plastic films can only be glued on one side and cannot be glued tightly at the later stage, and thickness of the woven films or plastic films is uncontrollable caused by the fact that the woven films or plastic films are glued unevenly by the rollers, and the like can be solved.

Description

technical field [0001] The invention relates to the field of packaging material processing, in particular to a gluing device for a plastic-lined woven bag. Background technique [0002] The plastic-lined woven bag is a kind of lining with a plastic film attached to the ordinary woven bag. The plastic-lined woven bag is used to hold products with small particles or moisture-proof products. [0003] The plastic lined woven bag is a packaging material made by laminating and rolling the woven film and the plastic film. The plastic lined woven bag is generally unwound through the rolled woven film and the plastic film during production. Apply glue on the inner surface of the woven film or thin plastic, and then glue and roll it by rolling. In the existing gluing operation in the production of plastic-lined woven bags, the glue is usually applied by rollers. The problems that exist when gluing woven films or plastic sheets are as follows: [0004] 1. The woven film or plastic fi...

AI Technical Summary

Problems solved by technology

[0004] 1. The woven film or plastic film can only be glued on one side, which will cause the phenomenon that the woven film and the plastic film will not be tightly bonded in the later stage, and the roller will apply uneven glue to the woven film or plastic film;

[0005] 2. The thickness of the woven film or thin plastic coating is uncontrollable. When the woven film or plastic thin coating is glued, it is often necessary to add glue to the roller, so that the continuous gluing action cannot be performed
