Laminating roller device of a composite machine

Abstract

The invention provides a doubling roller device of a combination machine. The doubling roller device is provided for solving the problems that a film and paper cannot be pressed tightly, bubbles are formed and low quality is caused due to the fact that the degree of the wrap angle of a doubling roller of a doubling roller device of an existing combination machine is too large in the paper feedingprocess and the pull-up printing force is greater than the pressure of a pressure roller. According to the doubling roller device of the combination machine, provided by the invention, a film guide wheel and a paper guide plate additionally arranged can press paper downwards before paper is fed into the doubling roller, so that the wrap angle of the doubling roller is reduced, and the pull-up printing force is reduced accordingly. The film and the paper can be pressed tightly to avoid bubble formation, and the product quality is improved. The doubling roller device can also be provided with anoutlet transition guide wheel, a film guide plate, a film inlet guide wheel, an outlet guide plate, an inlet transition guide wheel, a product outlet guide wheel and other guide wheels, so that the motion trails of the film and products are more stable and normative, and movement is smooth.

Description

technical field [0001] The invention relates to the field of composite paper production, in particular to a bonding roller device of a composite machine. Background technique [0002] A compound machine is a device that produces loaded paper. The production process is as follows: the raw paper goes through the unwinding process, the paper back coating process enters the back coating oven, and then the raw material enters the paper film bonding process; In the film bonding stage process, the paper film bonding process is completed with the raw material paper, and then the production process of the composite paper is completed through the drying process, peeling process, coloring process, and winding process. Therefore, it can be seen that the paper film laminating process is the most important process for the composite machine to produce composite paper, and the most important device in the paper film laminating process is the laminating roller device. [0003] At present, ...

Problems solved by technology

[0004] This application provides a laminating roller device of a laminating machine to solve the problem that the laminating roller device of an existing laminating machine has an excessively large wrapping angle when the laminating roller feeds paper, causing the upward pulling force to be greater than the pressure of the pressing roller , resulting in the inability to be crushed between the film and the paper, forming air bubbles, resulting in low quality problems
