Description

Technical Field

[0001] The utility model relates to the technical field of film packaging, in particular to a tray frame for film packaging. Background Art

[0002] Plastic film refers to film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, which is mainly used for packaging and as a coating layer. After the film is prepared, it is often rolled into a film roll using a roll core to facilitate subsequent packaging and transportation. A pallet is a medium that converts static goods into dynamic goods, and is a cargo platform.

[0003] The prior art discloses a pallet rack for film packaging (authorization announcement number CN215248182U). This patented technology can, by arranging a movable base under the pallet and placing the rack, pallet and movable base under the discharge end of the film roll conveyor, enable the film rolls output on the conveyor to automatically fall into the rack in sequence. The operator only needs to push the movable base, which saves time and effort and has high work efficiency.

[0004] Although the above can achieve protection for the film, the existing pallet rack for film packaging has a relatively uniform way of fixing the film, which will result in the inability to place film rolls of different sizes on the pallet rack, and it is easy to cause the film rolls to fall. In addition, film rolls of different models or sizes may be squeezed and rubbed during transportation, causing damage and increasing costs. In order to solve the above problems, we have made improvements and proposed a pallet rack for film packaging. Utility Model Content
