Problems solved by technology

[0002] At present, the contact positioning device of the wide-width biaxial stretching film winder used to manufacture stretching film in the industry adopts a frame structure, and the wall panels on both sides are connected by beams. This type of mechanical structure is complex, low in reliability, and high in cost. The operating space of the contact roller and the tension roller is narrow, and the positioning is inaccurate, which is very inconvenient for installation and maintenance

Abstract

The invention provides a contact positioning device of a broad biaxially oriented film winder, comprising a left C-type engine base, a right C-type engine base, a drive part, a driven part, a tension roller and a contact roller, wherein two ends of a film shut-off mechanism, the tension roller and the contact roller are assembled on the left C-type engine base and the right C-type engine base respectively by the drive part and the driven part, the contact roller is arranged above the tension roller and the film shut-off mechanism is arranged above the contact roller. When in operation, a contact roller drive motor drives the contact roller to be contacted with a reeled film, and stretch and wind the reeled film; along with the increase of the diameter of the reeled film, a linear motor also drives a contact roller bearing seat to enable the contact roller to move backwards and continues winding; when winding is finished, the film shut-off mechanism rotates downwards under the action of a hydraulic system thereof, a blade thereon shuts off the film and then resets; and the reeled film after winding is taken down and a hollow reel is installed, a tension roller drive motor drives the tension testers at the two sides to measure the tension of the winding film, and winding is carried out on the reeled film repeatedly.

Description

Technical field: [0001] The invention relates to the technical field of film stretching machinery, in particular to a contact positioning device for a wide-width biaxial stretching film winder. Background technique: [0002] At present, the contact positioning device of the wide-width biaxial stretching film winder used to manufacture stretching film in the industry adopts a frame structure, and the wall panels on both sides are connected by beams. This type of mechanical structure is complex, low in reliability, and high in cost. The operating space of the contact roller and the tension roller is narrow, and the positioning is inaccurate, which is very inconvenient for installation and maintenance. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a contact positioning device for a wide-width biaxially stretched film winder with reasonable structure and high positioning accuracy. [0004] In orde...
