[0002] A heat shrink film trimming device is a specialized mechanical device used to cut the edges of heat shrink film. During the packaging process, this device can precisely cut the heat shrink film to the required size to meet the packaging needs of different products. It typically consists of a film feeding mechanism, a trimming blade assembly, and a drive system, and the cutting operation is performed automatically or semi-automatically. The application of heat shrink film trimming devices can significantly improve packaging efficiency, ensure packaging quality, and reduce material waste.

[0005] In view of this, the present invention provides a heat shrink film trimming device, which can solve the problem of large size of traditional heat shrink film trimming devices, making it convenient to carry and store, and convenient for temporary use.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a heat shrink film edge cutting device, which includes a cutting mechanism, a positioning mechanism, and a storage mechanism.

[0008] Based on the above technical solution, the heat shrink film trimming device of this utility model can be further improved as follows:

[0009] The cutting mechanism includes a lower cutting blade and an upper cutting blade. The lower cutting blade is a long strip structure with its sidewalls fixedly connected to a first cutting blade. The length of the first cutting blade is equal to the length of the lower cutting blade. The lower cutting blade has grooves on both sides of the first cutting blade to accommodate the upper cutting blade.

The right angle of the cross-section of the first cutting blade is in contact with the lower cutting blade, and the right angle of the cross-section of the second cutting blade is in contact with the upper cutting blade.
