Description

Technical Field

[0001] The utility model mainly relates to the technical field of belt conveyor devices, in particular to a belt conveyor device with an automatic deviation correction function. Background Art

[0002] Belt conveyors are important components of mechanical equipment such as security inspection machines, logistics sorting, production lines, product testing equipment, and metallurgical and mining equipment. During the use of the above-mentioned mechanical equipment, the belt moves under the drive of the rollers, thereby driving the objects placed on the belt to move. However, various reasons such as processing errors, assembly errors, wear and tear, and loose belts due to long-term use often cause the belt to deviate from the rollers. The belt wears more after deviation, which shortens the service life of the belt. Therefore, it is particularly important to correct the deviation of the belt during the use of the belt conveyor. However, the existing belt conveyor has a poor correction effect during use and requires manual debugging on a regular basis, which increases the workload and causes deviations in the material conveying direction, affecting the processing quality of the material.

[0003] Therefore, we provide a belt conveyor device with an automatic deviation correction function to solve the defects of the existing technology. Utility Model Content
