TECHNICAL FIELD
[0001] The utility model relates to mechanical drive technical field especially relates to a self-rotating pulley spring structure. BACKGROUND
[0002] In the conveyor belt drive device, the self-rotating pulley spring structure can be used to maintain the proper tension of the belt. For example, on the conveyor belt of the automated production line in the factory, as the belt is used, the belt will be loosened due to factors such as wear and tear and temperature changes. The self-rotating pulley spring structure automatically compensates for this slackness, ensuring that the belt always maintains sufficient friction between the driving pulley and the driven pulley to ensure the stable conveying of the material.
[0003] In the prior art, when the belt is elongated, the spring is stretched, and through its elastic force, the pulley is pulled in the direction of tensioning the belt. The proper belt tension ensures that there is sufficient friction between the belt and the pulley. This friction is crucial for the stable conveying of the workpiece, as it prevents the workpiece from slipping on the belt.
[0004] However, in actual use, if the spring cannot effectively stretch and retract, and the front pulley cannot swing and rotate to adapt to the force and closely adhere to the workpiece to drive the workpiece to rotate, it is difficult to achieve cost savings, the production cycle will be correspondingly increased, and the skill requirement of the workers will be improved. Because of the lack of the stretchability of the spring and the self-adaptive rotation ability of the pulley, more complex and expensive mechanical structures and control systems are needed to ensure the normal operation of the workpiece during the workpiece processing or conveying process. Not only will this increase the manufacturing cost of the equipment, but also because of the increased complexity of the equipment, the production cycle will inevitably be prolonged. At the same time, the operation and maintenance of such a complex device require workers to have higher skill levels, otherwise it is difficult to ensure the stable operation of the equipment and the smooth progress of the production, therefore, in view of the above problems, a self-rotating pulley spring structure is proposed.
