In order to overcome this problem, glue is often applied to the paper tube. However, such an operation increases the production steps and reduces production efficiency. In addition, the film adhered to the glue cannot be used, resulting in a waste of film and an increase in production costs. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a winding device for a film blowing machine to improve the winding efficiency in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a winding device of a film blowing machine, comprising a frame, turntables are arranged on the inner walls of both sides of the frame, the turntables and the frame can rotate relative to each other, two winding rollers are arranged between the two turntables, the winding rollers and the turntables are detachably connected, a first driving component for driving the winding roller to rotate is installed in a cabinet on one side of the frame, and a second driving component for driving the turntable to rotate is installed in a cabinet on the other side, a roller shaft frame which can be lifted and lowered in a vertical direction is arranged in the frame, and the initial rotation of the roller shaft frame is rotatable.

At this time, one of the traction rollers is located at the lowest position of the turntable to fully unfold and flatten the film, which is convenient for subsequent cutting of the film. The setting of the traction roller effectively improves the accuracy and flatness of film cutting. Since the traction roller is directly fixedly connected to the turntable and cannot rotate, an auxiliary roller is set above it so that it can rotate with the transmission of the film, thereby improving the smoothness of the traction roller in conveying the film.
