Description

Technical Field

[0001] The utility model belongs to the field of conveying equipment, in particular to a right-angle turning machine with rollers of unequal length. Background Art

[0002] Conveying equipment is usually divided into conveyor belts and conveyor rollers, which are widely used in the field of logistics transportation due to their reliability, stability, low maintenance and use costs. However, whether it is a conveyor belt or a conveyor roller, the design of the turning point is still a difficult design problem to solve. The commonly used turning structure is still to use ordinary conveyor belts and tapered rollers for continuous turning. This structure has two common defects. First, the roller spacing at the corner is large and the turning radius is large, which is not conducive to the passage of materials and installation in a small space; second, whether it is directly conveyed by rollers or conveyed by roller-driven pulleys, in order to ensure that the material is more stable when turning, the roller needs to be designed as a tapered roller to achieve different linear speeds at each point, which will cause the turning surface to be unable to be horizontal, affecting the turning posture of the material.

[0003] A roller turning conveyor is disclosed in the patent document with application number "202020066938.4". It can be seen from the drawings and embodiments of the comparative documents that the device adopts a conical roller structure. Although the busbars above each roller remain horizontal and can ensure a certain stability when the material passes through, there is still a problem of excessive turning radius and more installation space occupied.
