A mounting plate 11 is arranged on the upper surface of the body 1, a fixed cylinder 12 is fixedly connected to the inner wall of the mounting plate 11, a driving component is arranged on the surface of the body 1, and a positioning component is arranged inside the fixed cylinder 12.

[0035] Refer to Figures 4 - 6 and Figure 7, the bottom of the fixing plate 2 is fixedly connected to the upper surface of the machine body 1. A visual window 10 is provided on the surface of the rotating cylinder 4. The visual window 10 facilitates the staff to check the grinding progress inside the rotating cylinder 4. The driving assembly includes a limiting plate 19. An electric push rod 18 is fixedly connected to the side wall of the limiting plate 19. The positioning assembly includes a knob 13. A bidirectional lead screw 14 is fixedly connected to the end of the knob 13. The knob 13 controls the rotation direction of the bidirectional lead screw 14. One end of the bidirectional lead screw 14 away from the knob 13 is rotatably connected to the inner wall of the fixed cylinder 12. The outer wall of the bidirectional lead screw 14 is threadedly connected to a positioning plate 16. There are two groups of positioning plates 16, and the distance between the two groups of positioning plates 16 approaching or separating each other is switched by the rotation direction of the bidirectional lead screw 14. A limiting rod 15 is slidably connected to the inner wall of the positioning plate 16. The end of the limiting rod 15 is fixedly connected to the inner surface of the fixed cylinder 12. An anti-slip pad 17 is fixedly connected to the inner surface of the positioning plate 16. The anti-slip pad 17 can increase the friction between the punching needle and the positioning plate 16. The lower surface of the limiting plate 19 is fixedly connected to the upper surface of the machine body 1. The output end of the electric push rod 18 is fixedly connected to the side wall of the mounting plate 11. The electric push rod 18 controls the fixed cylinder 12 to approach or move away from the rotating cylinder 4.

[0036] Refer to Figure 4 , Figures 6 - 7 , a grinding disc 20 is arranged inside the rotating cylinder 4. The side of the grinding disc 20 away from the motor 3 is arranged to be inclined inward, which is convenient for inserting into the inside of the two groups of sandpapers 9. A sliding rod 22 is fixedly connected to the outer wall of the grinding disc 20. The outer wall of the sliding rod 22 is slidably connected to the inner wall of the through groove 21. A through groove 21 is provided on the surface of the rotating cylinder 4. A limiting spring 23 is fixedly connected to the side wall of the sliding rod 22.

A cross plate 24 is fixedly connected to the surface of the rotating cylinder 4.

[0037] Working principle: The punch of the punching needle punches holes in the spinneret. When the punching needle needs to be polished, insert the end of the punching needle into the interior of the fixed cylinder 12, and turn the knob 13 forward. The knob 13 controls the two-way screw rod 14 to rotate and cooperate with the limit rod 15, so that the two groups of positioning plates 16 are close to each other until the two groups of anti-slip pads 17 position the end of the punching needle. Start the electric push rod 18, and the electric push rod 18 drives the punching needle until the punching needle is inserted into the interior of the rotating cylinder 4. Due to the extrusion force of the punching needle entering, the telescopic rod 5 and the telescopic spring 6 are in a compressed state, and the two groups of sandpaper 9 are attached to the outer wall of the punching needle. At the same time, the punch position forms an extrusion force on the grinding disc 20, and the limit spring 23 is stressed and in a stretched state. Let the sliding rod 22 move inside the through groove 21 toward one end of the motor 3, start the motor 3, and the motor 3 drives the rotating drum 4 to rotate slowly, so that the two sets of sandpaper 9 cooperate with the grinding disc 20 to grind the outer wall and the punch of the punching needle. After grinding, the electric push rod 18 is started again to drive the punching needle away from the rotating drum 4. After the sandpaper 9 has been used for a period of time, manually apply force to the magnet ring 28 to make it break away from the magnetic attraction of the magnet ring 1 7. Since the sandpaper 9 and the magnet ring 28 are fixed with double-sided tape or other adhesive, the sandpaper 9 is torn off the magnet ring 28 and separated, and the sandpaper 9 is replaced, so that the sandpaper 9 with different mesh sizes can be used to provide different degrees of grinding effects with the punching needle, thereby improving the subsequent punching effect of the punching needle.
