The staff controls the servo motor 11 to change the rotation direction of the first gear 12 to adjust the cleaning direction of the burrs of the plastic products placed on the top of the turntable seat 13. This step can change the cleaning direction of the burrs of the plastic products placed on the top of the turntable seat 13 during the cleaning process by setting the servo motor 11, the first gear 12, the turntable seat 13 and the fixed seat 14, thereby reducing the work When cleaning the burrs of plastic products, personnel need to manually adjust the direction of the plastic products whose burrs are to be cleaned to improve the efficiency of cleaning the burrs of plastic products.

By setting the suction cup 110, the plastic products whose burrs are to be cleaned can be adsorbed, thereby reducing the situation where the products are scratched or damaged when the burrs of plastic products are manually cleaned due to the loose fixation of the plastic products on the workbench.

[0026] Further, such as Figures 1 to 4As shown, the bottom of the cleaning box 1 is rotatably connected to a second gear 2; the second gear 2 is meshed with the first gear 12; a groove 21 is provided at the bottom of the cleaning box 1; a rack plate 22 is slidably connected to the middle of the groove 21; the rack plate 22 is meshed with the second gear 2; a push rod 23 is fixedly connected to the end of the rack plate 22; the push rod 23 is slidably connected to the side wall of one side of the cleaning box 1 and penetrates the side wall of the cleaning box 1; an elastic push plate 24 is fixedly connected to the middle of the push rod 23; an air pump 25 is fixedly connected to the outer wall of one side of the cleaning box 1; the elastic push plate 24 is arranged inside the air pump 25 and is slidably connected to the inner wall of the air pump 25; the elastic push plate 24 and the air pump 25 are interference fit; the air pump 25 A suction rod 26 is fixedly connected to the side wall away from the cleaning box 1; the end of the suction rod 26 is fixedly connected to the outer wall of the cleaning box 1; an air suction channel 27 is connected between the suction rod 26 and the suction cup 110; the suction channel 27, the suction rod 26, the first gear 12, the turntable seat 13, the fixing seat 14, the first fixing rod 15, the second fixing rod 16, the connecting rod 18, the pressing seat 19 and the suction cup 110 are connected; when working, the staff turns on the servo motor 11, and the servo motor 11 drives the first gear 12 to rotate. At this time, the second gear 2 meshing with the first gear 12 rotates with the rotation of the first gear 12, and the rack plate 22 meshing with the second gear 2 also starts to rotate in the groove 21 driven by the rotation of the second gear 2 The rack plate 22 slides, and at the same time, the push rod 23 and the elastic push plate 24 at the end slide inside the vacuum cylinder 25 to extract the air inside the vacuum cylinder 25. At this time, the air in the vacuum rod 26 connected to the end of the vacuum cylinder 25 is also extracted, and the air inside the suction cup 110 is also extracted from the suction channel 27 connecting the vacuum rod 26 and the suction cup 110. At this time, there will be a pressure difference between the inside and outside of the suction cup 110. This step is set by the meshing of the second gear 2 and the first gear 12, the second gear 2 and the rack plate 22. The positions of the second gear 2 and the rack plate 22 can be changed while rotating the first gear 12. The second gear 2, the groove 21, the rack plate 22, the push rod 23, the elastic push plate 2 4 and the vacuum cylinder 25 can exhaust the air inside the vacuum cylinder 25 by the elastic push plate 24 pumping inside the vacuum cylinder 25. By arranging the vacuum rod 26 and the vacuum channel 27, the air inside the vacuum cylinder 25 is exhausted and the air inside the vacuum rod 26 and the vacuum channel 27 is exhausted at the same time, so that the air inside the suction cup 110 at the other end connected to the vacuum channel 27 is exhausted together, so that there is a pressure difference between the suction cup 110 and the outside world, and the plastic product whose burrs are to be cleaned fixed on the middle of the suction cup 110 can be tightly adsorbed, the fixation of the plastic product whose burrs are to be cleaned is strengthened, and the situation that the burrs of the plastic products are manually cleaned due to the loose fixation of the plastic products on the workbench, which causes scratches or damage to the products.

[0027] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, the side wall of the cleaning box 1 is fixedly connected to a negative pressure wind box 3; the end of the negative pressure wind box 3 extends into the interior of the cleaning box 1; the top inner wall of the negative pressure wind box 3 is fixedly connected to an airflow redirecting baffle 31; the bottom of the negative pressure wind box 3 is fixedly connected to a dust collecting box 32; the dust collecting box 32 is arranged at the bottom of the airflow redirecting baffle 31; the top inner wall of the negative pressure wind box 3 is fixedly connected to a screen 33; the bottom end of the screen 33 is fixedly connected to the bottom of the negative pressure wind box 3; the air outlet of the negative pressure wind box 3 is fixedly connected to a ventilation plate 34; the outer wall of the ventilation plate 34 is provided with a fan 35; The fan blade 36 is fixedly connected to the middle of the output end of the fan 35; when working, the staff turns on the fan 35 while cleaning the burrs of the plastic products, and the fan 35 drives the fan blade 36 at the end to start rotating. The plastic dust and debris generated during cleaning are sucked into the negative pressure bellows 3 from the air inlet of the negative pressure bellows 3 through the rotation of the fan blade 36. Because the cross-sectional area of ​​the air duct inside the negative pressure bellows 3 becomes large, the air flow speed driven by the rotation of the fan blade 36 decreases, and the air flow is blocked by the air flow redirection baffle 31 to change the flow direction. At this time, the speed of the air flow The plastic dust and debris fall into the dust box 32 by descending and changing direction, and then the airflow passes through the screen 33 and is discharged from the ventilation plate 34. In this step, the fan blades 36 can continuously generate airflow, and the plastic dust and debris generated when cleaning the burrs of plastic products inside the cleaning box 1 are sucked into the negative pressure wind box 3. The airflow direction from the air inlet to the air outlet of the negative pressure wind box 3 can be changed by setting the airflow changing baffle 31. Because the airflow speed decreases and the airflow changes direction, the plastic dust and debris generated when cleaning the burrs of plastic products can be sucked into the negative pressure wind box 3. Dust and debris fall into the dust collecting box 32, and the plastic dust and debris are preliminarily collected. The screen 33 can be set to block the fine dust and debris remaining in the airflow, reduce the influence of the plastic dust and debris generated when cleaning the burrs of plastic products on the rotation of the fan blades 36, reduce the situation that the fan blades 36 are affected by the plastic dust and debris and the wind force is weakened, and the plastic dust and debris cannot be sucked into the negative pressure bellows 3, and at the same time reduce the pollution of the working environment caused by the plastic dust generated when cleaning the burrs of plastic products.

[0028] Further, such as Figure 2 and Figure 5As shown, the side wall of the screen 33 is fixedly connected with a magnetic block 4; the magnetic blocks 4 are multiple and evenly distributed on the side wall of the screen 33; the output end of the fan 35 is fixedly connected with multiple connecting ropes 41; the connecting ropes 41 are arranged correspondingly to the magnetic blocks 4; the end of the connecting rope 41 is fixedly connected with a magnetic ball 42; when working, the staff turns on the fan 35, the fan 35 will drive the connecting rope 41 fixed at the end to rotate, and the magnetic ball 42 fixed to the connecting rope 41 will also rotate with the rotation of the connecting rope 41. The connecting rope 41 and the magnetic ball 42 will attract each other because of their own special magnetic substances, and constantly knock on the surface of the magnetic ball 42 during the mutual attraction and pulling. In this step, the magnetic block 4 is set, The connecting rope 41 and the magnetic ball 42 can continuously knock the surface of the screen 33 through the mutual attraction and pulling of the connecting rope 41 and the magnetic ball 42, and the vibration generated by the knocking will shake the plastic dust and fragments accumulated on the surface of the screen 33 from the surface of the screen 33 into the dust collecting box 32, and the plastic dust and fragments are collected again, thereby reducing the situation where the airflow generated by the rotation of the fan blades 36 cannot enter the cleaning box 1 due to the blockage of the screen holes of the screen 33 by the plastic dust and fragments, and the plastic dust and fragments in the cleaning box 1 cannot be sucked into the negative pressure bellows 3, and the plastic dust generated when cleaning the burrs of plastic products can further reduce the pollution of the working environment caused by the plastic dust generated when cleaning the burrs of plastic products.

[0029] Further, such as Figure 2 and Figure 5 As shown, a dust box 5 is fixedly connected to the top of the dust box 32; a handle 51 is fixedly connected to the middle of the outer wall of the dust box 5; the length, width and height of the dust box 5 are the same as those of the dust box 32; during operation, the plastic dust and debris entering the negative pressure bellows 3 will fall on the top of the dust box 32, and then be caught by the dust box 5 fixed to the top of the dust box 32, and the staff can pull the handle 51 to pull out the dust box 5 and clean the dust box 5. In this step, the plastic dust and debris accumulated on the top of the dust box 32 can be cleaned by setting the dust box 5 and the handle 51, thereby reducing the situation where the internal work of the negative pressure bellows 3 fails due to excessive accumulation of plastic dust and debris in the dust box 32, and at the same time further reduces the situation where the plastic dust generated when cleaning the burrs of plastic products causes pollution to the working environment.

[0030] Further, such as Figures 1 to 4 As shown, a sponge pad 6 is fixedly connected to the middle of the suction cup 110; the sponge pad 6 is made of elastic material; in this step, by providing the sponge pad 6, the friction generated by the contact between the suction cup 110 and the plastic product can be reduced when the suction cup 110 adsorbs and fixes the plastic product, thereby reducing the wear of the plastic product when cleaning the burrs.

[0031] Working principle: the staff places the plastic product with burrs to be cleaned inside the cleaning box 1, adjusts the adjusting knob 17 to control the height of the second fixing rod 16 sliding inside the first fixing rod 15, adjusts the height to a distance that the staff can operate, and adjusts the inclination angle of the connecting rod 18 and the second fixing rod 16 at the same time, so that the plastic product with burrs to be cleaned can be fixed inside the pressing seat 19. At this time, the suction cup 110 fixedly connected to the middle part of the pressing seat 19 can tightly fix the plastic product with burrs to be cleaned. At this time, the staff turns on the servo motor 11 again, and the servo motor 11 drives the first gear 12 at the output end to start rotating. The rotation of the first gear 12 simultaneously drives the turntable seat 13 fixedly connected to the first gear 12 and the place The plastic product to be cleaned of the burrs placed on the top of the turntable seat 13 rotates, and the staff adjusts the cleaning direction of the burrs of the plastic product placed on the top of the turntable seat 13 by controlling the servo motor 11 to change the rotation direction of the first gear 12. The staff turns on the servo motor 11, and the servo motor 11 drives the first gear 12 to rotate. At this time, the second gear 2 meshed with the first gear 12 rotates with the rotation of the first gear 12, and the rack plate 22 meshed with the second gear 2 also starts to slide in the middle of the groove 21 driven by the rotation of the second gear 2. When the rack plate 22 slides, it drives the push rod 23 and the elastic push plate 24 at the end to slide inside the vacuum cylinder 25 to extract the air inside the vacuum cylinder 25. At this time, the rack plate 22 slides and drives the push rod 23 and the elastic push plate 24 at the end to slide inside the vacuum cylinder 25 to extract the air inside the vacuum cylinder 25. The air in the suction rod 26 connected to the end of the cylinder 25 is also sucked away, and the air inside the suction cup 110 is also sucked out from the suction channel 27 connecting the suction rod 26 and the suction cup 110. At this time, there will be a pressure difference between the inside and outside of the suction cup 110. When the staff is cleaning the burrs of the plastic products, they turn on the fan 35, and the fan 35 will drive the fan blades 36 at the end to start rotating. The plastic dust and debris generated during cleaning are sucked into the negative pressure bellows 3 from the air inlet of the negative pressure bellows 3 through the rotation of the fan blades 36. Because the cross-sectional area of ​​the air duct inside the negative pressure bellows 3 becomes large, the air flow speed driven by the rotation of the fan blades 36 decreases, and the air flow is blocked by the air flow redirecting baffle 31 to change the flow direction. At this time, the air flow speed is reduced. The plastic dust and debris fall into the dust box 32 through the sieve 33 and then are discharged from the ventilation plate 34. The staff turns on the fan 35, which drives the connecting rope 41 fixed at the end to rotate. At the same time, the magnetic ball 42 fixed to the connecting rope 41 also rotates with the rotation of the connecting rope 41. The connecting rope 41 and the magnetic ball 42 are attracted to each other because of their special magnetic substances. The surface of the magnetic ball 42 is constantly struck during the mutual attraction and pulling. The plastic dust and debris that enter the negative pressure bellows 3 will fall on the top of the dust box 32, and then be caught by the dust box 5 fixed to the top of the dust box 32. The staff can pull the handle 51 to pull out the dust box 5 and clean the dust box 5.
