Description

TECHNICAL FIELD

[0001] The present application relates to a box closing machine structure, in particular a double-station box closing machine with box number matching function. BACKGROUND

[0002] In the traditional single-file double-machine molding section, due to the delivery mode of the box divider being "upper box in front and lower box in back" during box division, the lower box of each pair of sand molds will be separated by a group of upper boxes after box division during the molding process. During box closing, the lower box can only be closed with the upper box behind it, resulting in the upper and lower box numbers always being offset by one number. This misnumbered box closing method cannot meet the requirements of modern factories for production precision, traceability, and production control, especially in production lines with high automation levels, where misnumbered box closing becomes a key bottleneck affecting production management and quality tracking. SUMMARY

[0003] To solve the above technical problems, the purpose of the present application is to provide a double-station box closing machine with box number matching function. The device adds an upper box storage position, i.e. an intermediate station, at the box closing position, so that the lower box can accurately match the upper box with the corresponding number during box closing, thereby achieving precise box closing with one-to-one box number correspondence to improve the automation level and management efficiency of the production line.
