Description

Technical Field

[0001] The utility model relates to the technical field of composite bag processing, and particularly relates to a paper-plastic composite bag hemming and gluing device. Background Art

[0002] A paper-plastic composite bag refers to a tubular packaging bag made of a paper-plastic composite bag base cloth formed by laminating kraft paper and a plastic woven bag through an intermediate layer of film lamination. In the process of making the bag, generally when laminating the woven cloth and the paper layer, a 4-5 cm paperless edge is left on one side of the woven cloth, and then the other side is stacked on the paperless edge through a center-sealing bag-making machine, and bonded by extruding an adhesive (after bonding, the overlapping part is on the back of the bag, commonly known as a center-sealing overlapping bag, abbreviated as a center-sealing bag). In order to stack neatly, generally the longitudinal two sides of the bag are folded into an M-shaped hem, so it is called an M-edge.

[0003] When using a paper-plastic composite bag to package PVC powder or other powdery materials, in order to prevent powder leakage and also facilitate smooth sealing after filling the goods, a paper-plastic composite bag hemming and gluing device with the publication number of: CN201471780U is proposed. The device includes: a glue basin for containing glue, a rubber roller immersed in the glue basin, a gravure roller closely adjacent to the rubber roller, and a plate roller adjacent to the gravure roller and equipped with a rubber plate; when the device works, each roller starts to rotate, the glue is transferred from the glue basin to the gravure roller through the rubber roller, and then transferred and coated to the part of the paper-plastic composite bag hemming and gluing device that needs to be coated with glue through the rubber plate by the plate roller.

[0004] However, in the actual use process, it is impossible to adjust the position of the plate roller according to the different thicknesses of different composite bags. When coating glue on composite bags with different thicknesses, it is necessary to disassemble and discard the corresponding plate roller for replacement, the operation is complex and cumbersome, and the practicability of the device is poor.
