Paper film laminating machine

Abstract

The invention provides a paper film laminating machine which comprises a rack, a film laminating assembly and a conveying assembly are sequentially connected between two side plates of the rack in the paper conveying direction, and a transition assembly is connected between the two side plates and located between the film laminating assembly and the conveying assembly. The transition assembly is provided with a limiting channel used for allowing paper output by the laminating assembly to penetrate through, the end, close to the laminating assembly, of the limiting channel is lower than the paper output height of the laminating assembly, and the other end of the limiting channel is higher than the paper feeding height of the conveying assembly, so that the laminated paper enters the conveying assembly in an S-shaped movement track. According to the paper film laminating machine provided by the invention, reverse pre-shaping of a broken warped surface can be realized after paper is laminated with a film, so that the laminated and broken paper can directly enter a next cementing process, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of paper laminating machines, in particular to a paper laminating machine. Background technique [0002] The paper laminating machine is a special equipment for paper lamination. The laminating material and paper material are pressed together by a rubber cylinder and a heating cylinder to form a paper-plastic product. The main steps of the paper laminating machine are as follows. Firstly, the paper material is sent to the laminating machine; secondly, the laminating material is heated by the heating roller and bonded to the paper material; then, the laminated product is pressed and transmit; finally, cut the coated paper. If the cut paper needs to be sold in the form of a whole booklet, then there will be a glue binding process after the paper is cut. [0003] In the prior art, there is a problem of low production efficiency when the coated paper is glued: on the one hand, due to the difference in shrinkage...

Problems solved by technology

[0003] In the prior art, there is a problem of low production efficiency when the coated paper is glued: on the one hand, due to the difference in shrinkage between the paper quality and the plastic film after the paper is coated, it is easy to make the two ends of the broken paper face toward the Different degrees of warping occur on one side of the film, so that the paper needs to be flattened before glue binding, that is, a corresponding additional process is required, which not only increases labor costs, but also affects the efficiency of glue binding; on the other hand, In the existing laminating machine structure, when the paper is broken, the corresponding driving mechanism is generally used to drive the two rollers to press against each other to generate a horizontal pressing force. Under the action of the synchronous rotation of the two rollers, the paper along the The middle position of the preset broken mark is pulled off. This method of paper breaking is easy to produce burrs at the section, which affects the quality of the paper; if the broken paper has relatively large burrs, it needs to be screened first. Then send it to the glue binding machine for the glue binding process, which also greatly affects the efficiency of glue binding after paper lamination
