Abstract
Description
Technical Field
[0001] The invention relates to the technical field of packaging box production, and in particular to a stacking device for producing and processing packaging boxes. Background Art
[0002] Packing boxes are mainly used to facilitate transportation, loading and unloading, and storage. Wooden boxes and corrugated wood pallets are generally used, and tin barrels or tin barrels are also used. According to the characteristics of the items being transported or loaded, national standards are used for protection. Honeycomb paper boxes are made by punching, cutting, and pasting honeycomb paperboards. Paper corner guards are pasted at the interface of the paperboards for reinforcement. According to actual needs, they can be designed into different configurations such as integral type, combined type (detachable), integrated bottom bracket type, etc., which is more conducive to handling and loading and unloading.
[0003] Cardboard is also called board paper. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard is defined as paperboard with a basis weight of more than 200g / m2 and a thickness of more than 0.5mm. It is mainly used to make paper packaging boxes, sandwich panels for packaging boxes, and other types of packaging materials for fragile goods. After the production of cardboard is completed, it needs to be stacked in batches for subsequent processing. The traditional stacking method is usually manual stacking, which is inefficient and can cause damage to the workers' waists if stacked for a long time. In addition, when the stacking height is too high, manual work cannot meet the stacking requirements. Summary of the invention

When the packaging box is clamped between the extrusion sheets 424, the lower curved rods 522 are set on both sides of the packaging box. At this time, the diamond frames 524 are set on both sides of the top of the packaging box, and the lower curved rods 522 on both sides of the diamond frame 524 are set above the packaging box to clamp and limit the stacked packaging boxes. When stacking packaging boxes of different thicknesses, the connecting shaft 53 drives the rotating rod 55 to rotate to adjust the clamping angle.

At this time, the pressing handle 24 drives the trimming knife 23 to slide on the surface of the bending frame 27, thereby cutting the burrs on the side of the packaging box to improve the processing flatness of the packaging box.
[0036] After the packaging box is trimmed, the output end of the motor 7 drives the conveyor belt 8 to rotate in the frame 1, so that the packaging box moves toward the side of the frame plate 3 along the conveyor belt 8. At this time, the two sides of the packaging box are against the limiting side parts 42. At this time, the limiting side parts 42 are deformed by being squeezed to limit the two sides of the packaging box to prevent the packaging boxes from tipping over when they are stacked.
[0037] The staff rotates the rotating rod 55 so that the rotating rod 55 drives the connecting shaft 53 to rotate, so that the rotating rod 55 drives the bending frame 52 to rotate, thereby adjusting the opening and closing distance between the bending frame 52 and the positioning seat 51 to stack and clamp packaging boxes of different thicknesses.
