PVC (polyvinyl chloride) film transportation device of composite film laminating machine

Abstract

The invention relates to a PVC film transportation device of a composite film laminating machine. The PVC film transportation device of the composite film laminating machine comprises a frame, guide rails are arranged on both sides of the frame separately, and fixing frames are arranged at both ends of each of the guide rails. The PVC film is in a roll, both ends of the PVC film are respectively arranged on a transportation guide roller in a sleeve mode to be formed as a whole with the transportation guide roller, and the PVC film and the transportation guide roller are cradled on a fixed frame of the frame. The portions of both ends of the transportation guide roller, which are connected with the frame, are provided with bearings respectively, and bearing rolling guide grooves are arranged on the guide rails. The bearings roll along the bearing rolling guide grooves or are fixed on the fixed frame. According to the PVC film transportation device of the composite film laminating machine, both ends of the rolled PVC film are respectively arranged on the transportation guide roller in a sleeve mode to be formed as a whole with the transportation guide roller and the PVC film and the transportation guide roller are cradled on the fixed frame of the frame, accordingly the transportation-finished rolled PVC film can be rolled to the guide rails and the portion of the frame on which the guide rails are arranged when the PVC film roll changing is needed, a new rolled PVC film can be replaced on the detachable portion of the frame, and the PVC film roll changing is easy and safe. The bearings which are more than one in number can bear greater gravity, so that the frequency of the PVC film roll changing is reduced to enable finished products to have fewer joints.

Description

technical field [0001] The invention belongs to the field of sending devices, and in particular relates to a PVC film sending device of a composite film laminating machine. Background technique [0002] With the increase of the application field of the film, the demand for the quantity of the film is increasing, and the performance requirements of the film are also getting higher and higher. Therefore, the composite film is more and more recognized by people due to its unique advantages. One of the five general-purpose plastics, it occupies an important position in the world's industrially produced polymers. Its products are widely used in various fields such as sea, land and air. Become an important part of the composite membrane. [0003] In order to improve the production efficiency of composite membranes and expand their production scale, mechanized production of composite membranes has become the mainstream of development. In the device for producing composite film, ...
