Description

Technical Field

[0001] The utility model relates to the field of carton production, in particular to a stacking device for carton conveying. Background Art

[0002] Carton: It is the most widely used packaging product. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers (color, feel) is also different.

[0003] For example, the authorization announcement number CN 219468467 U discloses a stacking device for EPE foam cartons, which relates to the field of material stacking technology. The device comprises a base, a separator pad is provided on the inner side of the base, connecting shafts are fixedly installed on both sides of the base, and the sides of the connecting shafts are provided with arc surfaces. The base is rotatably connected to side panels via the connecting shafts, the front ends of the side panels are fixedly connected to positioning rails, and the rear ends of the base are fixedly connected to back panels, and through holes are provided inside the side panels and back panels. By providing the side panels and back panels, the EPE foam cartons are separated, stacked and positioned in conjunction with the separator pads, and a frame structure is formed on the outside of the carton stack, so that the carton stack forms a whole. Since the EPE foam cartons are light in weight, while the base as the base of the frame structure is heavy in weight, the upward shift of the overall center of gravity of the EPE foam carton stack is slowed down during the increase of the stacking height, thereby improving the stability of the stacked cartons and reducing the safety risks caused by overturning. At the same time, the integrated EPE foam carton stack is also more convenient to carry.
