Description

Technical Field

[0001] The utility model relates to the field of winding machines, in particular to a winding mechanism for PE protective films. Background Technique

[0002] The PE protective film is the simplest high-molecular organic compound in structure and the most widely used high-molecular material in the world today. The PE protective film is based on a special polyethylene plastic film and is divided into high-density polyethylene protective film, medium-density polyethylene, and low-density polyethylene according to different densities. The biggest advantage of the PE protective film is that the protected products are not contaminated, corroded, or scratched during the processes of production, processing, transportation, storage, and use, and the original smooth and shiny surface is protected, thereby improving the quality and market competitiveness of the products. After the PE protective film is processed, it is wound by a winding machine. The existing winding mechanism cannot well adjust the positions of its additional winding wheels and the main winding wheel. Among them, there is a winding mechanism for a PE protective film with the application number of "CN201920455118.1". In the present utility model, by designing an annular frame, a limiting rod, a main gear, a secondary gear, a second bearing, a hole, a limiting insertion rod, and a limiting cap, the staff can pull the limiting rod to slide in the annular frame. When the position is determined, then use the limiting insertion rod to insert into the hole and at the same time penetrate the limiting rod for fixation. Finally, only need to thread the limiting cap on both ends of the limiting insertion rod. However, there are still certain deficiencies in the use of this winding machine: since it does not have a structure for cutting the protective film, after each roll of the protective film is wound, it is necessary to manually cut the protective film to achieve the next winding, and the wound protective film roll is relatively heavy and not easy to unload.
