AI Technical Summary
Technical Problem
Existing salt roll film rewinding equipment is prone to film misalignment and edge loosening during rewinding, affecting roll quality and the stability of subsequent automated packaging.
Method used
By sliding the limiting block with the limiting groove of the take-up roller, the distance between the mounting guard plate and the fixed guard plate is adjusted. Power is provided by a servo motor and a cylinder, and in conjunction with the limiting slide rod and compression spring, the lateral displacement of the film is restricted and the interlayer air is eliminated.
Benefits of technology
This achieves film edge alignment and tight winding, forming a neat cylindrical master roll, which improves the quality of the roll material and the stability of subsequent packaging.

Abstract
The utility model provides a kind of salt film winding device, it is related to salt film winding equipment technical field, and it includes: underframe, the right side of the underframe is equipped with fixed vertical frame;Fixed vertical frame is equipped with mounting seat;The left side of mounting seat is equipped with winding roller, by the sliding fit of limiting block and the limiting slide groove of winding roller, limit bolt rod is pushed to carry out left and right position adjustment to mounting baffle, the distance between mounting baffle and fixed baffle can be adjusted, the distance of mounting baffle and fixed baffle is matched with salt film winding width by control, the transverse displacement of film can be physically limited, forced winding edge alignment, protect film edge integrity, form neat cylindrical parent roll, the problem that existing salt film winding equipment is used, if the distance between the baffle of both sides of winding roller is much larger than film width, film can be left and right deviation when winding, film edge can be extruded, leading to winding material end surface is not neat, affect the feeding stability of subsequent automatic packaging machine.
