Description

Technical Field

[0001] The utility model belongs to the technical field of centering equipment, and in particular relates to a centering mechanism. Background Art

[0002] During the material conveying process, it is easy to be skewed or stuck, which requires manual intervention to correct. Therefore, most conveying equipment is equipped with a centering mechanism. The most common centering mechanism is to use two centering beams, each of which is driven by a cylinder or hydraulic cylinder to move in the opposite direction synchronously, so as to position the conveyed material to the middle position.

[0003] In order to ensure the centering effect, the length of the centering beam is usually not less than the length of the conveyed material, so the centering beam is usually long. When each centering beam is driven by a single cylinder or hydraulic cylinder, the centering beam is prone to shaking during translation, affecting the centering effect. When the cylinder or hydraulic cylinder drives the centering beam to translate, due to its own structural limitations, its reaction speed is slow, which affects the centering efficiency and reduces the conveying efficiency. In addition, the centering mechanism has multiple power sources, which is prone to asynchronism, further affecting the centering effect. Utility Model Content
