[0002] A plastic film roll refers to a plastic product that is easy to store, transport and use. It is produced by certain processing methods such as blow molding, extrusion, cast film, and calendering, and then wound on a cylinder of a certain diameter. The film is in roll form and can be cut into film materials of the required size as needed. Commonly used plastic film materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyester (PET), etc. Plastic film rolls are widely used in packaging, agriculture, construction, industry, household and other fields. For example, it is used as food packaging film, greenhouse film, geomembrane, stretch film, cling film, etc.

[0003] The patent document with application number CN202420023879.0 discloses a conveying device for a roll of plastic film, which includes a cargo box, a plurality of interlocking plates for embedding plastic film rolls are symmetrically installed on the side of the cargo box, and a through groove is opened in the plurality of interlocking plates. A U-shaped plate surrounding the cargo box is installed on the side of the cargo box, two rollers are symmetrically installed on one side of the bottom end of the cargo box, and a guide device is installed on the other side of the bottom end of the cargo box. The guide device includes a rectangular frame, and wheels are installed on both sides of the rectangular frame. The utility model replaces the box by adopting a box-type trolley. The invention replaces the plate-type trolley for transporting plastic film rolls, and the multiple interlocking plates symmetrically installed on the side of the cargo box are used for embedding the reels of the plastic film rolls, thereby increasing the single transport capacity of the trolley and improving the transport efficiency. Based on the search of the above patents and in combination with the plastic film roll transporting device in the prior art, it is found that the commonly used method now is to stack the plastic film rolls together.
