After rough processing of plastic products, there will be a large number of burrs on the surface edges. In order to ensure the use effect of plastic products, it is necessary to cut the burrs on the surface edges of plastic products.

[0003] In the utility model with the application number 202121262954.1, a plastic product deburring device is disclosed. The inner diameter of a columnar plastic product is inserted into a processing rod and fixed by an adsorption disc.

After all the plastic products are installed, the output end of the air cylinder is lowered to align the plastic products with the grinding position of the grinding roller, so as to deburr multiple plastic products at the same time. When the grinding roller runs for deburring, the second motor is started to drive the plastic products to rotate slowly for all-round deburring.

Detailed Description of the Preferred Embodiment

[0018] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0019] According to Figure 1 、 Figure 2 、 Figure 3As shown in the figure, this embodiment provides a device for removing burrs from plastic products, which includes a processing table 1, a bracket 2, a turntable 3, a die-changing mechanism, a lifting trimming mechanism, and a rotating mechanism. A bracket 2 is fixedly arranged in the middle of the processing table 1, and a turntable 3 is rotatably arranged in the middle of the processing table 1. The die-changing mechanism includes a first die holder 4, a first chute 5, a first positioning column 6, a limiting die 7, a first slide bar 8, and a first positioning hole 9. The first die holder 4 is fixedly arranged around the turntable 3 in a circular manner, and there are four groups of the first die holders 4 arranged around. On both sides inside the first die holder 4, first chutes 5 are symmetrically opened. A positioning column is fixedly arranged at the rear side inside the first die holder 4. A limiting die 7 is inserted into the first die holder 4. On both sides of the limiting die 7, first slide bars 8 are symmetrically fixed. A first positioning hole 9 is opened in the middle of the rear side of the limiting die 7. The first slide bars 8 are slidably matched with the first chutes 5, and the first positioning hole 9 is nested with the first positioning column 6. The lifting trimming mechanism is symmetrically arranged on the bracket 2, and a rotating mechanism is arranged at the bottom of the turntable 3. When removing burrs from plastic products, the limiting die 7 corresponding to the model of the plastic product is inserted into the first die holder 4 along the first chute 5, which is convenient for limiting and removing burrs from plastic products with different shapes, and solves the problem that plastic products with irregular shapes cannot be polished and trimmed by fitting.

[0020] The lifting trimming mechanism includes an electric telescopic rod 10, a second die holder 11, a second chute 12, a second positioning column 13, a trimming die 14, a second slide bar 15, and a second positioning hole 16. An electric telescopic rod 10 is fixedly arranged on one side of the bracket 2, and the telescopic end of the electric telescopic rod 10 is fixedly provided with a second die holder 11. Second chutes 12 are symmetrically opened inside the front side of the second die holder 11. A second positioning column 13 is fixedly arranged at the rear side of the second die holder 11. A trimming die 14 is slidably inserted into the second die holder 11. On both sides of the trimming die 14, second slide bars 15 are symmetrically fixed. A second positioning hole 16 is opened in the middle of the rear side of the trimming die 14. The second slide bars 15 are slidably matched with the second chutes 12, and the second positioning hole 16 is nested with the second positioning column 13. A trimming rib is fixedly arranged at the bottom of the trimming die 14, and the rib fits the edge of the plastic product. When removing burrs, the trimming die 14 corresponding to the shape of the plastic product is inserted into the second die holder 11 along the second chute 12. When the turntable 3 drives the limiting die 7 and the plastic product to rotate above the trimming die 14, the electric telescopic rod 10 extends to drive the second die holder 11 and the trimming die 14 to descend, and the rib fits the plastic product and cooperates with the limiting die 7 to cut off the burrs, preventing damage to the surface of the plastic product when polishing the burrs.

[0021] The rotating mechanism includes a motor 17, an infrared transceiver 18, and an infrared reflection block 19. The motor 17 is fixedly arranged at the bottom of the processing table 1. The output end of the motor 17 is drivingly connected to the center of the bottom of the turntable 3. The infrared transceivers 18 are symmetrically and fixedly arranged below the inner side of the bracket 2. The infrared reflection blocks 19 are fixedly arranged around the upper side of the turntable 3. The infrared transceivers 18 and the infrared reflection blocks 19 are at the same height. The infrared transceivers 18 are electrically controlled and connected to the motor 17. When deburring, the motor 17 drives the turntable 3 to rotate clockwise. After the infrared transceivers 18 emit infrared rays, they rotate with the turntable 3. When the infrared reflection blocks 19 rotate to the position of the infrared transceivers 18, the motor 17 temporarily stops rotating, facilitating the lowering of the trimming die 14 to cut off the burrs.

[0022] In the middle of the other side of the bracket 2, there is a fixed frame 20. A dust suction pipe 21 penetrates through the fixed frame 20. A collection box 22 is arranged at the bottom of the processing table 1. A dust collector 23 is fixedly arranged on the collection box 22. The upper end of the dust suction pipe 21 corresponds to the rear side position of the turntable 3. The lower end of the dust suction pipe 21 is communicated with the dust collector 23. During operation, the dust collector 23 is started to suck the cut burrs into the collection box 22 through the dust suction pipe 21.

[0023] Before using this plastic product deburring device, the limit die and the trimming die corresponding to the plastic product model are respectively inserted into the first die rack and the second die rack. The motor is started to drive the turntable to rotate. At the same time, the infrared transceiver emits infrared rays. When the turntable rotates to the corresponding position, the infrared reflection block reflects the infrared rays back. The motor pauses rotating according to the infrared signal received by the infrared transceiver, facilitating the removal of the burrs. After the turntable stops, the electric telescopic rod extends to drive the second die rack and the trimming die to descend and merge with the limit die. The convex strip below the trimming die fits the plastic product to extrude and remove the burrs on the edge of the plastic product. At the same time, the dust collector is started to extract air through the dust suction pipe. When the turntable drives the plastic product to rotate below the dust suction pipe, the removed burrs are sucked into the collection box through the dust suction pipe. When the turntable drives the plastic product to rotate to the front side of the processing table, manual feeding and discharging are carried out.
