Gluing device for corrugated paper production and method

Abstract

The invention belongs to the technical field of corrugated paper production, and particularly relates to a gluing device for corrugated paper production and a method. The gluing device comprises supporting plates, the upper surfaces of the supporting plates are fixedly connected with a fixed frame, and the two supporting plates are symmetrically distributed with the axis of the fixed frame as thecenter. According to the gluing device for corrugated paper production and the method , by arranging a gluing device body and a preheating feeding device, when the gluing device is used, an electric heating roller, a feeding rack, a gluing roller and a gluing groove rotate synchronously, corrugated paper is preheated and fed, the surface of the corrugated paper is in contact with the surface of the feeding rack and the inner wall of the gluing groove, and the corrugated paper is preheated and then glued, so that the problems that more glue is wasted, harmful substances such as formaldehyde arecontained in the glue, and the harmful substances in the manufactured corrugated paper exceed the standard due to a mode of gluing large-area papaer surface in an existing corrugated paper productiongluing and bonding process are solved.

Description

technical field [0001] The invention relates to the technical field of corrugated paper production, in particular to a gluing device and method for corrugated paper production. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board. According to the size of the corrugated board, it is divided into: A, B, C , E, F five types. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Used as packaging for food or digital products, it is relatively environmentally friendly and widely used.

Problems solved by technology

[0003] In the production process of corrugated paper, after the paper is folded by a corrugating machine, it is glued and pasted together with the face paper. At present, when most corrugated paper production lines glue the corrugated paper and the face paper, most of them are glued on the face paper. Afterwards, it is pasted with corrugated paper, but in the actual bonding process, the surface paper is only bonded to the protruding part of the corrugated paper. The method of gluing the surface paper on a large area will not only waste more glue, but also contains Harmful substances such as formaldehyde, harmful substances in corrugated paper exceed the standard, so there is a need for a glue coating device and method for corrugated paper production
