Description

Technical Field

[0001] This utility model relates to the field of cardboard box production, and in particular to a cardboard conveying assembly with sorting and stacking functions. Background Technology

[0002] Conveying devices play a crucial role in the manufacturing, processing, and logistics of cardboard boxes. During the conveying process, cardboard boxes are prone to shifting along the conveyor path due to wear, improper adjustment, or uneven speed of the conveyor belt or chain. Uneven weight distribution of the cardboard boxes can also cause them to shift during transport. This shifting results in uneven sides of stacked cardboard boxes, affecting not only their appearance but also subsequent processing steps such as labeling, packaging, and boxing. Shifting boxes can also cause blockages or malfunctions in the conveyor system, reducing production efficiency.

[0003] Most existing carton conveying devices only have basic conveying functions and lack the ability to sort cartons. Although some conveying devices are equipped with simple correction devices, their correction effect and stability are often limited, failing to meet the production requirements of high precision and high efficiency. In addition, existing conveying devices are often only suitable for cartons of specific sizes and weights. For cartons of different specifications and materials, their conveying effect and adaptability are poor. This leads to the need to frequently change conveying devices or adjust conveying parameters during the production process, increasing production costs and operational difficulty.

[0004] Therefore, it is necessary to propose a cardboard conveying assembly with sorting and stacking functions to solve the above problems. Utility Model Content
