Description

Technical Field

[0001] The utility model relates to the technical field related to carton packaging, and in particular to a cardboard switching device and a full-automatic packaging system. Background Art

[0002] Automated cardboard packaging is the process of packaging items in cardboard using automated technology and equipment, and the resulting packaged product. This includes: cardboard conveying: automatically conveying stacks of cardboard raw materials to specific locations on the packaging equipment; cardboard forming: folding, cutting, and die-cutting the cardboard according to pre-set procedures and product specifications to form a box or carton capable of accommodating the items; item loading: accurately placing the items into the pre-formed cardboard packaging using mechanical devices or robots; and sealing and packaging: sealing the cardboard containing the items.

[0003] In the current cardboard conveying process, different packaging products may require cardboard of different specifications, but the size and parameters of a single conveyor belt are usually fixed, making it difficult to flexibly adapt to various cardboard specifications. For example, when packaging larger items, a wider conveyor belt may be required, but a single conveyor belt cannot meet this demand. The entire conveying system needs to be replaced, increasing equipment costs and adjustment time. For cardboard of varying thicknesses, the pressure and friction of a single conveyor belt may not be effectively adjusted, resulting in poor conveying results. In addition, the layout of a single conveyor belt is usually relatively fixed, which may limit the overall layout and expansion of the packaging equipment. For example, if you want to add a new packaging process or equipment, you may be restricted by the position and direction of a single conveyor belt, making it difficult to carry out reasonable layout planning.

[0004] Currently, no effective solution has been proposed to the problem that a single conveyor belt in related technologies is difficult to flexibly adapt to cardboards of various specifications, affecting the overall layout and expansion. Utility Model Content
