Description

Technical Field

[0001] This utility model relates to the field of plastic production and processing technology, and in particular to a deburring device for the production of plastic parts. Background Technology

[0002] In the current plastic parts manufacturing industry, plastic products are widely used in many industries such as electronics, automobiles, and packaging due to their advantages such as light weight, low cost, and strong plasticity. As various industries have increasingly stringent requirements for the quality and appearance of plastic parts, deburring, as a key process after plastic parts are formed, is directly related to product quality and market competitiveness.

[0003] Traditional deburring methods for plastic parts mostly rely on manual grinding and punching. Manual grinding is highly dependent on worker experience and skill, resulting in low efficiency and inconsistent quality. Prolonged high-intensity work can easily lead to worker fatigue, causing unstable deburring results and failing to meet the needs of large-scale industrial production. While punching improves efficiency to some extent, it is only suitable for plastic parts with regular shapes and simple structures. For complex and irregularly shaped plastic parts, it is not only difficult to accurately remove deburrs but also easily damages the plastic parts themselves, resulting in a high scrap rate. At the same time, with the rapid development of automated production technology, plastic parts production is gradually moving towards automation and intelligence. The demand for efficient, stable deburring equipment that can adapt to various shapes of plastic parts is becoming increasingly urgent. Against this backdrop, a deburring device has been developed that can flexibly adjust the working position and easily replace grinding components. It can efficiently handle the deburring of straight-edged plastic parts, cleverly handle the complex surfaces of irregularly shaped plastic parts, and simultaneously collect grinding debris. This device is key to solving the pain points of plastic parts production and improving the overall production level of the industry, and has extremely important practical significance and broad market application prospects.

[0011] Optionally, a limiting bolt is threaded to the front end of the rotating shaft, and the rear end of the limiting bolt is in close contact with the grinding roller.

[0012] The above technical solution uses limiting bolts to limit the grinding roller, preventing it from falling off during the grinding process, and also increases the speed of replacing the grinding roller, making it easier to replace the grinding roller.

[0013] Optionally, the support rod is provided with a third sliding groove inside, and a spring is fixedly connected to the bottom inner wall of the third sliding groove.

[0014] The above technical solution improves space utilization and restricts the direction of movement by setting a third groove in the support rod.

[0015] Optionally, the upper surface of the spring is elastically connected to a second slider, and the outer surface of the second slider is slidably connected to a third groove.

The front surface of the anti-slip pad 13 is in close contact with a grinding roller 14. A limit block 17 is provided on the outer surface of the rotating shaft 12. The outer surface of the limit block 17 is slidably connected to the grinding roller 14 via a limit groove 16. A first drive motor 2 is fixedly connected to the front end of the base 1. The output end of the first drive motor 2 is fixedly connected to... A threaded rod 3 is threaded to a slide rod 6. An L-shaped plate 10 is fixedly connected to the side surface of the first slider 8. A roller 25 is rotatably connected to the front surface of the L-shaped plate 10. Double-sided adhesive 18 is bonded to the inner wall of the roller 25. A limit bolt 15 is threaded to the front end of the rotating shaft 12. The rear end of the limit bolt 15 is in close contact with the grinding roller 14. A third slide groove 19 is provided inside the support rod 9. A spring 21 is fixedly connected to the bottom inner wall of the third slide groove 19. A second slider 20 is elastically connected to the upper surface of the spring 21. The outer surface of the second slider 20 is slidably connected to the third slide groove 19. A fixing rod 22 is fixedly connected to the front end of the second slider 20. A support roller 23 is rotatably connected to the outer surface of the fixing rod 22. A pin 24 is snap-fitted to the inner wall of the second slider 20. The end of the pin 24 away from the support roller 23 is snap-fitted to the groove provided on the side surface of the support rod 9.

[0034] Working principle: When deburring plastic parts is required, the first drive motor 2 at the front end of the base 1 is started first. The first drive motor 2 drives the threaded rod 3 at its output end to rotate. Since the threaded rod 3 is threadedly connected to the slide rod 6, the slide rod 6 will slide in the first slide groove 4 inside the base 1 under the action of thread transmission. The connecting piece 7 at the rear end of the slide rod 6 moves accordingly, thereby driving the first slider 8 at the upper end of the connecting piece 7 to slide in the second slide groove 5 of the base 1. The sliding of the first slider 8 causes the support rod 9 connected to it and the various components installed on the support rod 9 to move as a whole. Move the device to adjust it to a suitable working position and align it with the plastic part to be processed. Depending on the burr condition of different plastic parts and the specific requirements for deburring, the old grinding roller 14 can be removed from the rotating shaft 12 by loosening the limiting bolt 15 at the front end of the rotating shaft 12. Due to the cooperation between the limiting block 17 and the limiting groove 16, the grinding roller 14 can be accurately positioned with the rotating shaft 12 during installation. After installing the appropriate grinding roller 14, tighten the limiting bolt 15 again so that its rear end is in close contact with the grinding roller 14, and fix the grinding roller 14 on the rotating shaft 12.

[0035] The anti-slip pad 13 on the outer surface of the rotating shaft 12 increases the friction between it and the grinding roller 14, ensuring that the grinding roller 14 can rotate stably and synchronously with the rotating shaft 12 during rotation without slippage. The second drive motor 11 on the rear surface of the support rod 9 is activated, and the second drive motor 11 drives the rotating shaft 12 to rotate at high speed, thereby causing the grinding roller 14 mounted on the rotating shaft 12 to start rotating. During the grinding process, the spring 21 on the inner wall of the bottom of the third slide groove 19 inside the support rod 9 applies an upward force to the second slider 20 that is elastically connected to it. The support roller 23 on the front end fixing rod 22 of the second slider 20 pushes the plastic part upward under the action of the spring 21.

[0036] For straight-edged plastic parts, this upward force makes the contact between the plastic part and the grinding roller 14 more compact and stable, which is beneficial for the grinding roller 14 to efficiently and evenly grind the burrs on the plastic part, improving the quality and effect of deburring. When encountering irregularly shaped plastic parts, due to their irregular surface shape, a larger grinding range may be required. At this time, the operator can manually pull down the support roller 23 to make the second slider 20 slide downward in the third slide groove 19, compressing the spring 21. After the support roller 23 is adjusted to the appropriate position, the pin 24 is inserted into the inner wall of the second slider 20, and the end away from the support roller 23 is connected to the groove on the side surface of the support rod 9 in a snap-fit ​​manner, thereby fixing the second slider. Positioning block 20 lowers the support roller 23, expanding the grinding range of the grinding roller 14 on irregularly shaped plastic parts. This allows for better adaptation to the surface shape of the parts and effective grinding of rough edges. During grinding, a large amount of grinding debris is generated. A roller 25 is rotatably connected to the front end of the L-shaped plate 10 on the side surface of the first slider 8. Double-sided adhesive 18 is adhered to the inner wall of the roller 25. As the grinding operation proceeds, the double-sided adhesive 18 on the rotating roller 25 collects and adheres to the grinding debris, preventing it from scattering on the worktable or the surface of the plastic parts, maintaining a clean working environment, and preventing the debris from adversely affecting the grinding process and the quality of the plastic parts.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
