Description

TECHNICAL FIELD

[0001] The utility model relates to a film winding shaft moving structure. BACKGROUND

[0002] Film, especially plastic film, has been widely used in various fields, such as packaging of food, medicine and medical devices. Since the film is thin, it is easy to wrinkle or scratch, so the film produced by the extruder needs to be wound into a film roll for transportation, storage and subsequent processing.

[0003] When winding the film, the film produced by the film winding equipment is usually wound on a winding shaft made of paper or plastic material. As the length of the film wound on the winding shaft increases, the diameter of the film roll also increases. Since the size and winding capacity of the film winding equipment are limited, when the diameter of the film roll reaches a predetermined size, the film needs to be cut off, the film roll reaching the predetermined size needs to be unloaded, and a new winding shaft needs to be replaced to continue winding.

[0004] At present, there are many winding shaft replacement devices, but when replacing the new winding shaft, the recovery station and the winding station often move and touch the winding internal roller body. Usually, many groups of rollers are needed to cooperate to complete the winding. The winding is the replacement of the winding roller in the winding station to complete the winding roller. This replacement process is relatively mature, but the new winding roller is usually manually transported to the winding station, which is low in efficiency and easy to cause damage to the equipment, and needs to be improved.
