Film roll feeding device

Abstract

The invention provides a film roll feeding device and belongs to the technical field of film processing. The film roll feeding device comprises a left clamping assembly, a right clamping assembly, a two-way driving cylinder and a horizontal sliding supporting base which is arranged on a fixed supporting base in a front-back sliding manner; a lead screw and a lead screw nut are in threaded connection; the upper end of a lifting piston rod of a lifting cylinder is connected with an upper bearing base; the left clamping assembly and the right clamping assembly are symmetrically arranged on the left side and the right side of the upper bearing base; the right end of a left piston rod of the two-way driving cylinder is fixed to a left piston; the left end of the left piston rod is connected with a left bearing block; the left end of a right piston rod is fixed to a right piston; the right end of the right piston rod is connected with a right bearing block; and a bearing cylinder body is provided with a left gas valve, a middle gas valve and a right gas valve. The film roll feeding device automatically achieves feeding of a film roll, is reasonable in structure and high in automation degree, guarantees stable feeding of the film roll, and is good in reliability.

Description

technical field [0001] The invention relates to the technical field of film processing, in particular to a film roll feeding device. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. Thin film is scientifically explained as: a 2-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Films are widely used in electronics, machinery, printing and other industries. There is no unified regulation on the classification of films. Usually people are accustomed to the following three classification methods: (1) Classification according to the raw materials used in film forming: polyethylene film, polypropylene film, polyvinyl chloride film and polyester film. ⑵Classified according to the purpose of the film: there are agricultural films (according to the ...

AI Technical Summary

Problems solved by technology

The film is generally wound on the film roll to form a film roll, and the film roll is generally loaded onto the film roll bracket manually. Because the film roll has a large quality, the labor intensity of manual loading is relatively high. low production efficiency

Because the center of the film roll that winds the film is generally hollow, the two ends of the film roll need to be installed on the film roll bracket. Since the underside of both ends of the film roll must be installed on the film roll bracket, the common automatic feeding device cannot realize
