The main function of a spinning machine is to process short fibers or filaments into continuous yarns through a series of technological steps such as drafting, twisting, winding, etc. There are various types of spinning machines, including ring spinning machines, friction spinning machines, etc., and each type of spinning machine has its specific technological characteristics and applicable scenarios.

[0003] A Chinese patent discloses a movable operation platform for a spinning machine, with the publication number CN205443551U, which includes a base, a motor, a transmission chain, a driving wheel, a driven wheel, and a movable platform. The transmission chain is sleeved outside the driving wheel and the driven wheel. The driving wheel is driven by the motor. The driven wheel and the motor are respectively arranged at both ends of the base. It provides power through the motor to move the movable operation platform of the spinning machine, realizing the full mechanization of the movement of the movable platform, thereby reducing the labor intensity and improving the labor efficiency. It is not only simple to operate, but also the equipment structure is simple, easy to install and maintain.

[0004] When this movable operation platform of the spinning machine is in use, since the middle of the transmission belt needs to be tightened by the driven wheel to prevent the waste yarn from being wound around the round belt and prevent the overall round belt from falling off, but during operation, it is very easy to have working vibrations, which will change the gap of the round belts at both ends. If the diameter width of the driven wheel is not adjusted in time, it is very easy to fail to tighten, resulting in the belt falling off and causing problems in the overall spinning work.
