[0002] In the production process of bearing bushes, sometimes the type of bearing bushes produced on the bearing bush production line needs to be changed. Since the outer diameter size of each bearing bush type is different, once the bearing bush type is changed, the height of the conveyor belt for discharging materials needs to be adjusted accordingly. At present, the existing technology usually supports the conveyor belt by a support plate, and a waist groove is provided on the support plate. The conveyor belt is fixedly connected to the waist groove by bolts;

[0003] In the prior art, a utility model patent with publication number CN 217675120 U proposes a screw lifting adjustment device, through which the conveyor belt is supported. When the height of the conveyor belt needs to be adjusted, the height of the conveyor belt can be adjusted by rotating the rotating body, which is convenient and easy to operate, saving time and effort. In addition, the screw thread matching relationship can realize continuous and stepless adjustment of the height, and the adjustment accuracy is high.

[0004] However, the lifting and lowering movement of the screw controlled by the sprocket and chain is not stable. During long-term use, the tightness of the chain needs to be adjusted regularly to maintain the stability of the chain. The operation is more troublesome. The chain is also more likely to break and become disjointed during use, affecting the safe operation of the equipment. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content
