[0028] Two support plates 12 are fixedly arranged on the side wall of the mounting plate 1, and a fixed plate 14 is slidably arranged between the two support plates 12. A moving groove is opened on the fixed plate 14, and a motor 15 is installed in the moving groove. A linear screw 16 rotatably connected to the moving groove is fixedly arranged on the output shaft of the motor 15. By using the cooperation between the motor 15 and the linear screw 16, the grinding wheel 20 can move back and forth left and right to form a motion cycle. A threaded block 17 is spirally connected to the linear screw 16, and the threaded block 17 slides. The movable plate 18 is arranged in the movable groove, and the side wall of the threaded block 17 is fixedly provided with a movable plate 18, and a motor 19 is installed on the movable plate 18. A grinding wheel 20 is fixedly provided on the output shaft of the motor 19, and the grinding wheel 20 is rotatably connected to the bottom of the movable plate 18. A turning mechanism 23 located below the bearing platform 4 is also fixedly provided on the mounting plate 1; by setting the turning mechanism 23, the bearing platform 4 can be rotated 180°, and the grinding wheel 20 can grind both sides of the plastic product at the same time by moving back and forth for one cycle, thereby improving the grinding efficiency of the plastic product.

[0029] Specifically, a pressure display 10 is installed on the side wall of the clamping plate 8, and the pressure display 10 is connected to a pressure sensor 11, which is embedded in the rubber pad 9.

After the plastic product is clamped, the electric push rod 13 is started and the fixing plate 14 is driven to move, and the grinding wheel 20 is adjusted to just contact the side of the plastic product, and then the motor 1 15 and the motor 2 19 are started. The motor 2 19 directly drives the grinding wheel 20 to rotate at a high speed, and the motor 15 drives the grinding wheel 20 to move back and forth through the linear screw 16, thereby forming a grinding operation on the side of the plastic product.

[0032] Embodiment 2:

[0033] Combination Figure 1 and Figure 3 As shown, on the basis of embodiment 1, the flip mechanism 23 includes two fixed blocks 231 fixedly connected to the mounting plate 1, and the fixed block 231 is rotatably connected to a swing arm 233 via a rotating shaft 232. A fixing pin 234 is fixedly provided on the swing arm 233, and a tension spring 235 is connected between the rotating shaft 232 and the fixing pin 234. A movable hole is opened on the swing arm 233, and a slide rod 236 is slidably arranged in the movable hole. The slide rod 236 is fixedly connected to a "U"-shaped groove opened at both ends of a tooth plate 237, and the tooth plate 237 is meshed with the gear ring 3.

[0034] Specifically, a connecting frame 21 is fixedly provided on the side wall of the threaded block 17 , a pushing block 22 is fixedly provided at the bottom of the connecting frame 21 , and the pushing block 22 is located between the two swing arms 233 ; under the action of the pushing block 22 , the automatic rotation of the supporting platform 4 is realized.

[0035] Furthermore, two symmetrically arranged limit blocks 2310 are fixedly disposed on the side wall of the fixing block 231 ; the limit blocks 2310 can be used to limit the rotation angle of the swing arm 233 to ensure that the supporting platform 4 can rotate exactly 180°.

[0036] Furthermore, a guide rail 238 is fixedly provided on the side wall of the tooth plate 237, and the guide rail 238 is slidably arranged in a guide rail seat 239, and the guide rail seat 239 is fixedly arranged on the mounting plate 1; the arrangement of the guide rail 238 and the guide rail seat 239 can make the tooth plate 237 more stable when moving laterally.

[0037] According to the embodiment, the push block 22 moves with the movement of the grinding wheel 20 through the connecting frame. When the grinding wheel 20 moves to both sides of the fixed plate 14, the push block 22 can push the swing arm 233 to rotate. When the swing arm 233 moves toward a vertical state, the tension spring 235 is gradually stretched. After exceeding the vertical state, the swing arm 233 is quickly pulled to the other side by the tension of the tension spring 235. During this process, the tooth plate 237 meshes with the gear ring 3 to rotate the support platform 4 180°, and the tension spring 235 always has tension, thereby ensuring that the angle of the support platform 4 does not change during the grinding process.

[0038] Through the above embodiments, it can be known that the use process of the device is as follows: the plastic product is placed on the carrier 4, and then the adjusting screw 6 is rotated to drive the slider 7 to move, and the slider 7 drives the clamping plate 8 to move, so that the plastic product is clamped between the fixing seat 5 and the clamping plate 8. In this process, the rubber pad 9 will be subjected to the same extrusion force, and the clamping pressure is displayed in real time on the pressure display 10 by the pressure sensor 11. The staff can accurately control the clamping force through the pressure value. After the plastic product is clamped, the electric push rod 13 is started and the fixing plate 14 is driven to move, and the grinding wheel 20 is adjusted to just contact with the side of the plastic product, and then the motor 15 and the motor 2 19 are started. The motor 2 19 directly drives the grinding wheel 20 to rotate at a high speed, and the motor 15 drives the grinding wheel 20 through the linear screw 16. The grinding wheel 20 moves laterally to one side. When the grinding wheel 20 contacts the side of the plastic product, it can grind it. Then the linear screw 16 continues to drive the grinding wheel 20 to move to one side. At this time, the push block 22 moves with the movement of the grinding wheel 20 through the connecting frame. When the grinding wheel 20 moves to one side of the fixed plate 14, the push block 22 can push the swing arm 233 to rotate. When the swing arm 233 moves to a vertical state, the tension spring 235 is gradually stretched. After exceeding the vertical state, under the tension of the tension spring 235, the swing arm 233 will be quickly pulled to rotate to the other side. In this process, the tooth plate 237 meshes with the gear ring 3, thereby rotating the support platform 4 180°. Then the grinding wheel 20 returns to move, and the other side of the plastic product can be polished.
