Description

Technical Field

[0001] The utility model relates to the technical field of sand pool expansion camp boats, and specifically relates to a precise carton folding mechanism. Background Art

[0002] During the processing of cartons, a folding mechanism is required to fold the cardboard. The cardboard is folded along the pre-pressed creases, and then adhesively bonded in the subsequent process to form a box body, completing the folding process of the carton.

[0003] When folding a cardboard with indentations, it is necessary to align the folding component with the cardboard box in advance. After alignment, the cardboard is pushed along the indentations to complete the folding. During the folding process of the cardboard by the folding component, since the conveyor uses a conveyor belt to convey the cardboard, when the cardboard is being conveyed, the edge of the cardboard will extend beyond the edge of the conveyor belt and rub against the inner side wall of the device operating platform. During the rubbing process, the problem of the cardboard having a flared opening will occur, and at the same time, the appearance of the cardboard's rough edge is relatively poor.

There are several groups of the first rotating rods. One end of several groups of the first rotating rods is fixedly connected to one end of the transmission wheel, and the transmission wheel provides a rotational force for one of the groups of the first rotating rods.

[0008] Optionally, the folding component includes a load-bearing frame disposed directly above the device body, a third fixing block fixed at the edge position of the device body, a support column fixed at the top end of the support column, a hydraulic rod disposed inside the support column, and a second pushing component fixed at the top end of the support column.
