However, traditional manual disassembly and box feeding methods have problems such as low efficiency, high labor intensity, and prone to errors, making it difficult to meet the needs of modern high-speed production.

[0003] At present, some automated equipment can realize automatic feeding of packaging boxes, but the following technical defects still exist: most existing equipment cannot automatically cut the strapping straps and still requires manual intervention, which affects the overall degree of automation; there is a lack of automatic collection or recycling mechanism for the strapping straps after cutting, and scattered strapping straps may be entangled in equipment components or mixed into the production line, causing malfunctions or safety hazards. Summary of the Invention

[0004] The object of the present invention is to provide an automatic box feeding device, which solves the problems of low efficiency, high labor intensity, and easy errors in the existing manual disassembly and box feeding methods.
