[0002] In traditional processes, plastic gloves are a common household item with extensive applications in daily life and production, especially in the catering and medical fields, where they have broad application prospects. Packaging and palletizing are key processes before products leave the factory, directly affecting production efficiency, packaging consistency, and logistics turnover efficiency.

[0003] Traditional manual boxing and palletizing processes have many pain points: On the one hand, manual operation accounts for a high proportion, requiring multiple processes such as carton feeding, glove box stacking, box insertion, sealing, and palletizing to be completed separately. This results in high labor intensity, low operating efficiency, and poor accuracy in manual stacking and box insertion, which can easily lead to problems such as skewed cartons and insecure carton sealing, resulting in inconsistent glove box packaging quality. On the other hand, existing automated equipment often suffers from fragmented functions and poor coordination. Carton feeding, box processing, sealing, and palletizing processes require multiple machines to work together, which requires a large area, is complex to debug, and has limited adaptability. It is difficult to quickly switch between different sizes of cartons and boxes, and cannot meet the flexible needs of large-scale production.
