[0025] Working principle: When the utility model is in use, the user drives the threaded rod 8 to rotate by starting the motor 7. Then, the threaded rod 8 drives the threaded ring 9 to move.

Then, the cross bar 12 drives the U-shaped plate 15 to move through the spring 14. Thus, the U-shaped plate 15 drives the roller 16 to press tightly against the belt 5. Among them, through the setting of the spring 14, the resilience of the spring 14 can always apply an upward extrusion force to the U-shaped plate 15, thereby ensuring that the U-shaped plate 15 drives the roller 16 to always be in close contact with the belt 5. In this way, the tension of the transmission between the belt and the turntable can be adjusted to ensure that the belt is always in close contact with the turntable, and further ensure the transmission efficiency of the belt to the turntable.

[0026] To sum up: For this adjustable sand mill, the threaded rod 8 drives the threaded ring 9 to move, so that the threaded ring 9 drives the cross bar 12 to move in the vertical direction through the support rod 13. Then, the cross bar 12 drives the U-shaped plate 15 to move through the spring 14. Thus, the U-shaped plate 15 drives the roller 16 to press tightly against the belt 5. In this way, the tension of the transmission between the belt and the turntable can be adjusted to ensure that the belt is always in close contact with the turntable, and further achieve the purpose of ensuring the transmission efficiency of the belt to the turntable.
