Automatic laminating device

Abstract

The invention belongs to the technical field of laminating devices, especially relates to an automatic laminating device. The device comprises a controller, a laminating mechanism and a sensing mechanism, the laminating mechanism comprises a second motor, an upper die cylinder, an upper smoothing roller, an upper heating rubber roller, an upper paper outlet rubber roller, a lower paper outlet rubber roller, a lower heating rubber roller, a lower smoothing roller and a lower die cylinder; a first motor, an upper paper feeding roller and a lower paper feeding roller are arranged in front of thelaminating mechanism; the power output shaft of the first motor is in transmission connection with an upper paper inlet shaft, the upper paper outlet rubber roller is in transmission connection with the lower paper outlet rubber roller, the linear speeds of the outer walls of an upper heating roller, a lower heating roller, the upper paper outlet rubber roller and the lower paper outlet rubber roller are equal, and the first motor, the second motor, an infrared emitter and an infrared receiver are in signal connection with the controller. The automatic laminating device aims at accurately controlling the distance between two adjacent paper certificates through the controller matched with the sensing mechanism and the second motor, reducing waste of films and facilitating cutting of redundant films on the paper certificates after laminating is completed.

Description

technical field [0001] The invention belongs to the technical field of film covering devices, and in particular relates to an automatic film covering device. Background technique [0002] In the printing and distribution of jewelry paper certificates, after printing and stamping the paper certificates, the paper certificates need to be laminated. [0003] Most of the existing laminating devices manually put paper certificates into the laminating device one after another. The distance between two adjacent paper certificates is not precisely controlled, and after the laminating device is opened , has been running, once the distance between two adjacent paper certificates is too large, it will lead to a lot of waste of film. [0004] At the same time, after the film covering is completed, when cutting the redundant film on the paper certificate, the distance between adjacent paper certificates on the film is not fixed, so there is a problem that it is not convenient to cut. ...
