Description

Technical Field

[0001] The utility model belongs to the field of turnover box conveying devices, and in particular relates to a centering device for a turnover box roller conveyor. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are acid-resistant, alkali-resistant, oil-resistant, non-toxic and odorless. They can be used to hold food, etc. They are easy to clean, and parts turnover is convenient. They are neatly stacked and easy to manage. They are suitable for transportation, distribution, storage, circulation and processing in factory logistics. Turnover boxes can be used in conjunction with a variety of logistics containers and workstation equipment, and can be used in various warehouses, production sites and other occasions. Today, when logistics management is increasingly valued by enterprises, turnover boxes help complete the universal and integrated management of logistics containers, and are essential for production and distribution companies to carry out modern logistics management.

[0003] When using roller conveyors to transport turnover boxes, if the axis of the head drive roller or the tail redirection roller of the roller conveyor is not perpendicular to the center line of the conveyor, the conveyor belt will deviate at these key points. This misalignment will cause the tightness of the conveyor belt to be different on both sides of the roller, which will lead to uneven traction along the width direction; manufacturing defects or damage to the roller itself, such as excessive roundness of the roller, poor welding of the web, and errors in turning the shaft, can cause the roller to be eccentric, causing the conveyor belt to deviate and fail to meet the transportation of turnover boxes.
