[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In order to facilitate the grinding of the PTFE sleeve, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a support frame 1, an adjustment mechanism, a grinding unit and a positioning component. The adjustment mechanism is arranged on the support frame 1. After the positioning component fixes the polytetrafluoroethylene sleeve to be ground, the position of the grinding unit is changed by the adjustment mechanism, so that the polytetrafluoroethylene sleeve is placed in the grinding area. The two ends of the polytetrafluoroethylene sleeve are respectively sleeved on the limiting rubber ball 16. Through the elasticity of the rubber, the squeezed limiting rubber ball 16 will react on the polytetrafluoroethylene sleeve, thereby fixing the polytetrafluoroethylene sleeve.

[0020] In order to facilitate the grinding of PTFE sleeves of different sizes, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjusting mechanism includes a fixed block 2 arranged on a supporting frame 1, a groove is provided in the fixed block 2, and a motor 3 is provided on the outer side of the fixed block 2, the power output end of the motor 3 extends into the groove and is connected to a screw 4, a movable plate 5 is sleeved on the screw 4, and slide grooves 6 are provided on both sides of the groove, a bearing sleeve is sleeved on the outer side of the screw 4, an internal thread matching the thread on the outer surface of the screw 4 is provided in the bearing sleeve, and the bearing sleeve is provided on the lower surface of the movable plate 5, so when the screw 4 is driven to rotate by the motor 3, the bearing sleeve follows the rotation, but the slider moves in the slide groove 6 to convert the rotational motion into linear motion, so that the movable plate 5 moves on the screw 4, and the motor 3 adopts a forward and reverse motor 3, thereby controlling the forward and reverse rotation of the screw 4 to realize the left and right movement of the movable plate 5. The grinding unit includes a support plate 7 arranged on a movable plate 5, a scraper 8 is connected to the outer side of the support plate 7 through a fixed plate, a grinder 9 is arranged on the scraper 8, and the power output end of the grinder 9 extends to the outer side of the scraper 8 and is connected to a grinding wheel 10.

The support frame 1 is arranged on a base 11, and a support column is also arranged on the base 11. A recovery bucket 12 is arranged on the top of the support column, and a storage box 13 is arranged vertically below the recovery bucket 12. During the grinding process, the waste generated will fall into the storage box 13 through the recovery bucket 12, and can be uniformly processed later to avoid the staff from cleaning, thereby improving convenience. The positioning assembly includes vertical plates 14 arranged on both sides of the upper surface of the recovery bucket 12, and positioning columns 15 are arranged on the opposite surfaces of the two vertical plates 14. Limiting rubber balls 16 are arranged at equal intervals around the outer side of the positioning columns 15.
