Description

Technical Field

[0001] The present invention relates to the technical field of PE film palletizing, in particular to a PE film intelligent palletizing line. Background Art

[0002] PE film, or polyethylene film, refers to a film produced from PE particles. PE film has properties such as moisture resistance and low moisture permeability. PE film is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. It uses special polyethylene (PE) plastic film as the base material. According to different manufacturing methods, control methods and densities, PE film products with different properties such as high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene can be prepared. The biggest advantage of PE protective film is that the protected product is not polluted, corroded or scratched during production, processing, transportation, storage and use, and the original smooth and shiny surface is protected, thereby improving the quality and market competitiveness of the product.

[0003] At present, in the process of mineral water packaging, PE film is a commonly used outer packaging product, that is, PE film is needed to prepare the outer packaging bag of mineral water bottles, and in the process of PE preparation, an intelligent palletizing line is needed to palletize the PE film rolls. When palletizing the PE film rolls, the PE film rolls need to be stacked on a pallet, and then an automatic film wrapping machine is used to wrap a layer of outer protective film around the stacked PE film rolls. On the one hand, the PE film itself can be protected from damage caused by external collisions and other factors. On the other hand, the PE film rolls can be tightened to avoid the collapse of the PE film rolls stacked on the pallet, thereby avoiding the problem of disordered palletizing. However, the existing automatic film winding machine for PE film rolls adopts a spiral winding method from bottom to top. The number of protective film layers on the surface of the wound PE film rolls is small, and the tightness between the protective films is low, which affects the tightening performance of the PE film rolls. Therefore, a PE film intelligent palletizing line is urgently needed to solve the above problems. Summary of the invention
