Film coiling device with pressure adjustment mechanism

Abstract

The invention relates to a film coiling device with a pressure adjustment mechanism. The film coiling device comprises a contact roller shaft mounted on a coiling machine body, a contact roller, rotating brackets, pressing wheels and a gas expansion shaft located on the upper part of the contact roller, and the film coiling device is characterized in that the rotating brackets are mounted betweenthe two sides of the contact roller shaft and the contact roller, rotating bracket driving air cylinders are mounted at the lower ends of the rotating brackets, the rotating bracket driving air cylinders are mounted on a coiling machine seat, the upper ends of the rotating brackets are connected with rotatable rotating plates, the pressing wheels are mounted at the upper ends of the rotating plates, rotating plate driving air cylinders are mounted at the lower ends of the rotating plates, the rotating plate driving air cylinders are connected with a first reversing valve, a pressure adjustmentvalve and a pressure gauge through a gas path pipeline, and the rotating bracket driving air cylinders are connected with a second reversing valve through a gas path pipeline. The film coiling devicehas the advantages that through the pressure adjustment mechanism, acting pressure of the rotating brackets can be set according to the hardness and thickness of film products, so that the pressure applied to coiling of different PVC products is adjusted more flexibly, and thus the quality and efficiency of the film products are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of calendering equipment for plastic products, in particular to a film winding device with a pressure regulating mechanism. Background technique [0002] In the production process of PVC calendered film, the last process is the coiling process of PVC film, so the coiling process will definitely play an important role in ensuring the quality of film products. In the prior art, during the winding process of the PVC film, although the rotating brackets for fixing the air shaft are installed on both sides of the air shaft, the force value of the action is fixed and cannot be adjusted. The same pressure values ​​are applied. However, in the actual production process of PVC film, there are differences in softness, hardness and thickness of the film. Compared with soft and thick products, the pressure value of the rotating bracket required for the hard thin product film during the crimping process is greater. In ...
