The adjustment work is cumbersome, which seriously affects the efficiency of grinding work and has poor applicability.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A grinding device for plastic products includes a base, a support frame fixedly connected to the upper end of the base, an electric telescopic rod fixedly connected to the upper end of the support frame, and a grinding mechanism provided at the lower end of the electric telescopic rod.
[0007] The polishing mechanism includes a motor fixedly connected to the lower end of an electric telescopic rod. A first rod is fixedly connected to the output end of the motor. A second rod is slidably connected to the lower end of the first rod. A spring is fixedly connected to the upper end of the second rod. Rotating rods are rotatably connected to both sides of the first rod. Rectangular openings are provided on both sides of the upper end of the first rod. A round block is fixedly connected to the upper end of the second rod. The round block is slidably connected to the rectangular opening. A first polishing block is rotatably connected to the outer side of the rotating rod.
[0008] Preferably, the first grinding block has a groove inside, and a second grinding block is slidably connected inside the groove;

[0020] Reference Figure 1-3 A grinding device for plastic products includes a base 1, a support frame 2 fixedly connected to the upper end of the base 1, an electric telescopic rod 3 fixedly connected to the upper end of the support frame 2, the electric telescopic rod 3 being a driving device, and in the prior art, a grinding mechanism is provided at the lower end of the electric telescopic rod 3.
[0021] The grinding mechanism includes a motor 4 fixedly connected to the lower end of an electric telescopic rod 3. The electric telescopic rod 3 can drive the motor 4 to move up and down. The output end of the motor 4 is fixedly connected to a first rod 5. The motor 4 drives the first rod 5 to rotate. The lower end of the first rod 5 is slidably connected to a second rod 11. The second rod 11 can move up and down inside the first rod 5. The upper end of the second rod 11 is fixedly connected to a spring 10. The spring 10 can reset the second rod 11. Rotating rods 14 are rotatably connected to both sides of the first rod 5. Rectangular openings 13 are opened on both sides of the upper end of the first rod 5. The movement of the upper end of the second rod 11 drives the circular block 8 to move. The upper end of the second rod 11 is fixedly connected to the circular block 8. The circular block 8 is slidably connected to the rectangular opening 13. The outer side of the rotating rod 14 is rotatably connected to a first grinding block 7. The movement of the rotating rod 14 drives the first grinding block 7 to move.
[0022] During operation, the plastic part to be polished is placed on the upper part of the base 1. The electric telescopic rod 3 drives the motor 4 to move downwards. The motor 4 then drives the first rod 5 and the second rod 11 to move downwards. The second rod 11 contacts the plastic part, causing it to move upwards relative to the first rod 5. The upward movement of the first rod 5 causes the circular block 8 to move upwards, which in turn causes the rotating rod 14 to rotate. The rotation of the rotating rod 14 moves the first polishing block 7. Under the force of the rotating rod 14, the first polishing block 7 is able to adhere to the inner wall of the plastic part. The rear motor 4 starts to rotate, which drives the first rod 5 to rotate. The first rod 5 drives the rotating rod 14 to rotate, which in turn causes the first grinding block 7 to rotate, thus grinding the inner wall of the plastic part. During operation, the second rod 11 moves upward relative to the first rod 5, causing the round block 8 to drive the rotating rod 14 to move, thereby making the first grinding block 7 fit against the inner wall of the plastic part. Through the rotation of the rotating rod 14, the first grinding block 7 can fit against the inner wall of the plastic part with different inner diameters for grinding, thus improving the applicability of the device.
[0023] Reference Figure 3 The first grinding block 7 has a groove 12 inside, and a second grinding block 6 is slidably connected inside the groove 12. The second grinding block 6 can move up and down inside the groove 12. The lower end of the second grinding block 6 is located at the lower end of the plastic part, so that the interior of the plastic part can be ground more thoroughly during grinding.
[0024] Reference Figure 3 The lower end of the second polishing block 6 is provided with a ball bearing, which can reduce the friction between the lower end of the second polishing block 6 and the plastic part.
[0025] Reference Figure 1 Limiting blocks are provided on both sides of the upper end of the base 1. The limiting blocks are used to limit the plastic parts.
[0026] Reference Figure 3 The lower end of the second rod 11 is fixedly connected to a rotating block 9. During operation, the second rod 11 and the rotating block 9 rotate relative to each other, which can prevent the second rod 11 from contacting and rotating with the plastic part, thus protecting the plastic part from damage.
[0027] Working principle: During operation, the plastic part to be polished is placed on the upper part of the base 1. At this time, the electric telescopic rod 3 drives the motor 4 to move downward. The motor 4 drives the first rod 5 and the second rod 11 to move downward. The second rod 11 contacts the plastic part, causing the second rod 11 to move upward relative to the first rod 5. The upward movement of the first rod 5 causes the circular block 8 to move upward. The circular block 8 causes the rotating rod 14 to rotate. The rotation of the rotating rod 14 causes the first polishing block 7 to move. Under the force of the rotating rod 14, the first polishing block 7 can fit against the inner surface of the plastic part. The motor 4 starts rotating, which drives the first rod 5 to rotate. The first rod 5 drives the rotating rod 14 to rotate, which in turn causes the first grinding block 7 to rotate, thus grinding the inner wall of the plastic part. During operation, the second rod 11 moves upward relative to the first rod 5, causing the round block 8 to drive the rotating rod 14 to move, thereby making the first grinding block 7 fit against the inner wall of the plastic part. Through the rotation of the rotating rod 14, the first grinding block 7 can fit against the inner wall of the plastic part with different inner diameters for grinding, thus improving the applicability of the device.
