Adjusting roller device for glue-free film laminating machine

Abstract

The invention discloses an adjusting roller device for a glue-free film laminating machine. The device comprises a thermo-compression device and an adjusting roller device, wherein the thermo-compression device comprises a hot steel roller and a rubber roller which are oppositely arranged; the surface of the hot steel roller is closely attached to the surface of the rubber roller; a heating device is arranged inside the hot steel roller; the adjusting roller device is arranged at the film feeding end of the thermo-compression device, and comprises an alternating current motor and a connecting shaft connected to an output shaft of the alternating current motor; a speed reducer is arranged on the connecting shaft, and is used for respectively driving a ball screw to rotate; the ball screw is connected with an adjusting aluminum roller, and is used for controlling lifting of the adjusting aluminum roller. According to the adjusting roller device, the speed of film laminating can be flexibly adjusted under the situation that temperature and pressure are not variable, the adjusting aluminum roller can move smoothly, film feeding smoothness can be guaranteed, wrinkles influencing production quality can be avoided, a flattening mechanism is capable of flattening wrinkles which are generated in film lamination and caused by speed changes of the hot steel roller, cooling is carried out quickly, and yield is increased.

Description

technical field [0001] The invention relates to the field of glue-free lamination processing, in particular to a regulating roller device of a glue-free lamination machine. Background technique [0002] Laminating technology has experienced a history of about 20 years in China. It can increase the strength of various color-printed papers after lamination, produce a sense of thickness and texture, capture the "temperament" of color-printed paper, and use it to make various bags, packaging boxes, book covers, samples and other products . The usual laminations are in the form of adhesive laminations, such as solvent-based adhesives, water-based adhesives, and hot-melt adhesives (pre-coated on the film and hot-pressed). [0003] The non-adhesive film does not use conventional biaxially stretched polypropylene film (OPP), but uses high-pressure polyethylene as the main material of PE film, because PE film has better thermal melting and plasticity. After special strong treatmen...

AI Technical Summary

Problems solved by technology

Due to the limitation of temperature and pressure, when the speed is increased, the force of thermocompression will attenuate, which will deteriorate the composite effect, the bond will not be firm, and it will be easy to fog. If it is too slow, the production efficiency will be reduced or even foaming.
