Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and specifically, to a burr cleaning device for plastic barrels. Background Technique

[0002] During the production process of plastic barrels, since plastic barrels are generally formed by injection molding, after the plastic barrels are injection-molded, there will be burrs at the edge positions of the plastic barrels, and thus it is necessary to clean the burrs on both sides of the edge positions of the plastic barrels.

[0003] Regarding burr cleaning, there are many existing technologies, for example:

[0004] Chinese Patent Application No. 202311038323.5 discloses an installation frame, a circular frame, a fixing component, etc. A circular frame for placing plastic barrels is rotatably connected through the central position of the middle part of the installation frame, and fixing components are arranged in the middle of the left and right sides inside the circular frame. In the present invention, the plastic barrel is placed in the circular frame and clamped and fixed by the fixing component, and then the servo motor is started, so that the first grinding block and the second grinding block move downward to contact the inner and outer sides of the edge position of the plastic barrel. Then the driving motor is started to drive the circular frame to rotate. The rotation of the circular frame drives the plastic barrel to rotate through the fixing component, and the first grinding block and the second grinding block clean the burrs on the inner and outer sides of the edge position of the plastic barrel, with more comprehensive cleaning and improved cleaning effect.

[0005] When the existing technology is used for burr cleaning, due to the single cleaning method, it can only clean cylindrical barrels and cannot clean conical barrels. When cleaning conical barrels, the burrs cannot be removed completely and need to be supplemented manually, and the plastic barrels may also be damaged, resulting in the inability to adapt to the burr cleaning of some plastic barrels and limited application range. In view of this, we propose a burr cleaning device for plastic barrels. Content of the Utility Model

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] During the production process of plastic barrels, since plastic barrels are generally formed by injection molding, after the plastic barrels are injection molded, there will be burrs at the edge positions of the plastic barrels, so it is necessary to clean the burrs on both sides of the edge positions of the plastic barrels.

[0024] Please refer to Figures 1 - 4As shown in the figure, this embodiment provides a burr cleaning device for plastic barrels, including a base 1. On the left and right sides of the top of the base 1, there are sliding grooves 11. A support plate 12 is fixedly connected to the top of the base 1. An installation plate 13 is fixedly connected to the top of the support plate 12. A rotating shaft 2 is rotatably connected to the middle of the bottom of the installation plate 13. The lower end of the rotating shaft 2 is fixedly connected to the center of a bevel gear 22. The number of bevel gears 22 is two, and their outer surfaces are meshed with each other. Considering that the burr cleaning of plastic barrels can only clean cylindrical barrels and cannot clean conical barrels, specifically as follows: A rotating shaft 2 is fixedly connected to the center of one of the bevel gears 22. Electric telescopic rods 23 are fixedly connected to both ends of the rotating shaft 2. A groove 24 is opened at the outer end of the electric telescopic rod 23. A fixing plate 25 is rotatably connected inside the groove 24. A circular hole 26 is opened on the outer surface of the fixing plate 25. A four-sided knife 29 is rotatably connected to the fixing plate 25. A bolt 27 is threadedly connected inside the circular hole 26. A nut 28 is threadedly connected to the outer surface of the bolt 27. In the prior art, when cleaning burrs, due to the single cleaning method, only cylindrical barrels can be cleaned, and conical barrels cannot be cleaned. When cleaning conical barrels, the burrs cannot be removed completely, and manual supplementation is required, which may also damage the plastic barrels, resulting in the inability to adapt to the burr cleaning of some plastic barrels and limited application range. By rotating the rotating shaft 2 to drive the bevel gear 22 to rotate, driving another bevel gear 22 to rotate, driving the electric telescopic rod 23 to rotate. Since the electric telescopic rod 23 is rotatably connected to the fixing plate 25, and a circular hole 26 is opened on the fixing plate 25, the inclination angle of the four-sided knife 29 can be determined by threadedly connecting the bolt 27 to the circular hole 26 on the fixing plate 25, and it can be adjusted at multiple angles, so that the burrs of the conical barrel can be rotated and cleaned, and the burrs of the cylindrical barrel can also be cleaned, improving the application range.

[0025] The improvement of this embodiment lies in:

[0026] By rotating the rotating shaft 2 to drive the bevel gear 22 to rotate, driving another bevel gear 22 to rotate, driving the electric telescopic rod 23 to rotate. The electric telescopic rod 23 is rotatably connected to the fixing plate 25. A circular hole 26 is opened on the fixing plate 25. The inclination angle of the four-sided knife 29 can be determined by threadedly connecting the bolt 27 to the circular hole 26 on the fixing plate 25, and it can be adjusted at multiple angles. When cleaning the burrs of the conical barrel, remove the bolt 27, rotate it to the ideal position and insert the bolt 27 into the circular hole 26 inside. When cleaning the burrs of the cylindrical barrel, insert the bolt 27 into the middle circular hole 26, meeting the burr cleaning methods of different plastic barrels and improving the application range.

[0027] Considering that the rotation of the rotating shaft 2 is not convenient, therefore, a first motor 210 is fixedly connected to the top of the installation plate 13. The end of the output shaft of the first motor 210 extends into the installation plate 13 and is fixedly connected to the top of the rotating shaft 2. By rotating the first motor 210 to drive the rotating shaft 2 to rotate, the convenience of the rotation of the rotating shaft 2 is realized, and the degree of automation is improved.

[0028] Considering that it is not easy for the generous flash to fall off after hanging, therefore, a groove 24 is provided at the outer end of the other end of the electric telescopic rod 23. A fixing plate 25 is rotatably connected inside the groove 24. A circular hole 26 is provided on the outer surface of the fixing plate 25. A four-sided brush 21 is rotatably connected to the fixing plate 25. A bolt 27 is threadedly connected inside the circular hole 26. A nut 28 is threadedly connected to the outer surface of the bolt 27. By providing a circular hole 26 on the fixing plate 25 and threadedly connecting the bolt 27 to the circular hole 26 on the fixing plate 25, the inclination angle of the four-sided brush 21 can be determined, and it can be adjusted at multiple angles, so as to realize the rotation and sweeping of the flash that has not fallen off the barrel after cutting, improving the efficiency.

[0029] Considering that the barrel is likely to tilt and fall during flash cleaning, therefore, a threaded rod 3 is rotatably connected to the right side of the support plate 12. An arc-shaped block 31 is fixedly connected inside the threaded rod 3. The outer end of the threaded rod 3 is fixedly connected to the end of the output shaft of the second motor 32. The outer end of the second motor 32 is fixedly connected to the inner outer surface of the side plate 33. The bottom of the side plate 33 is fixedly connected to a slider 34. The slider 34 is slidably connected to the inner surface of the chute 11. By driving the threaded rod 3 to rotate by the second motor 32, the threaded rod 3 moves in and out to drive the arc-shaped block 31 to move in and out, so as to realize the clamping of the barrel and prevent it from tilting and falling.

[0030] In summary, the working principle of this solution is as follows:

[0031] Manually unscrew the nut 28, remove the bolt 27, manually adjust the positions of the four-sided knife 29 and the four-sided brush 21. When adjusted to the ideal angle, align the circular hole 26 with the holes on the four-sided knife 29 and the four-sided brush 21, manually screw on the bolt 27 and then tighten the nut 28 from the outer surface of the bolt 27. At this time, adjust the distance of the electric telescopic rod 23 according to the size of the barrel, adjust to the appropriate angle, place the plastic barrel mouth up between the two arc-shaped blocks 31, connect the power supply to the two second motors 32 on both sides, make the threaded rod 3 rotate to drive the side plate 33 and the slider 34 to move back and forth, drive the arc-shaped block 31 to move back and forth, so that the arc-shaped block 31 clamps the barrel tightly and is not easy to fall off. Connect the power supply to the first motor 210. The rotation of the rotating shaft 2 drives the bevel gear 22 to rotate, driving the four-sided knife 29 and the four-sided brush 21 to rotate. The four-sided brush 21 removes the flash on the inner wall of the barrel and then sweeps it away. When scraping the relatively shallow outer wall of the barrel, the barrel can be clamped between the bolt 27 and the inner side of the four-sided brush 21 by the arc-shaped block 31 for scraping. When scraping the relatively deep outer wall of the barrel, the barrel can be held by hand so that the outer end of the four-sided knife 29 scrapes the flash on the outer wall of the barrel. After scraping, the barrel can be held by hand and the flash chips can be swept away at the outer end of the four-sided brush 21. For the removal of the flash at the top of the barrel, place the barrel mouth up and clamp and fix the barrel with the arc-shaped block 31 so that the bottom of the four-sided knife 29 scrapes. For the flash at the bottom of the barrel, invert the barrel, manually adjust the barrel to the appropriate position, clamp it with the arc-shaped block 31, and make the four-sided knife 29 scrape the flash at the bottom of the barrel, improving the scope of application and efficiency.
