Description

Technical Field

[0001] The utility model belongs to the technical field of burr treatment, and particularly relates to a burr treatment device. Background Art

[0002] Most plastic products are injection molded. Due to reasons such as material fluidity, mold structure defects, and improper molding processes, the edges of products often produce burrs due to excessive filling of materials, resulting in plastic overflow. The existing burr treatment device is provided with a bottom plate, a support frame, a grinding mechanism, a rotating mechanism, a rotating bottom plate, a dust suction mechanism, and a collection assembly. The support frame supports the grinding mechanism and the rotating mechanism on the surface of the bottom plate. The rotating mechanism and the rotating bottom plate cooperate to enable the plastic workpiece to rotate. When the plastic workpiece rotates, the burrs are ground off by the grinding mechanism, and the excess plastic burrs are ground into plastic particles. At this time, the dust suction mechanism can suck the plastic particles with the burrs ground off.

[0003] However, usually during mold forming, the burrs of the product are symmetrical. The existing burr treatment device can only grind one side, and the burrs in other directions need to be disassembled and the grinding position changed multiple times, resulting in low working efficiency. After retrieval, it is found that the technical solution provided by the utility model with the application number CN202223163086.9 also has the above problems. Utility Model Content

The output end of the linear motor 2 is fixedly connected to a bottom plate 4. The outer surface of the bottom plate 4 is slidably connected to the bracket 1. A first slide rail 3 is slidably connected to the left surface of the bottom plate 4. A sliding plate 6 is slidably connected to the upper surface of the bottom plate 4. A chute 5 is arranged on the upper surface of the bottom plate 4. The inner surface of the chute 5 is slidably connected to the sliding plate 6. A threaded rod 7 is threadedly connected to the inner surface of the sliding plate 6. A clamping block 8 is rotatably connected to the outer surface of the threaded rod 7. A second slide rail 9 is slidably connected to the lower surface of the clamping block 8. The outer surface of the second slide rail 9 is fixedly connected to the sliding plate 6. The clamping block 8 clamps and fixes plastic products of various specifications through the threaded transmission of the threaded rod 7 and under the limit of the second slide rail 9. The linear motor 2 drives the clamped plastic products to perform linear up and down movement to adjust the grinding height.

[0026] As Figure 2 - Figure 4As shown in the figure, a top plate 11 is fixedly connected to the outer surface of the bracket 1. The outer surface of the top plate 11 is fixedly connected to the first slide rail 3. The inner surface of the top plate 11 is fixedly connected to a double-headed motor 10. The output end of the double-headed motor 10 is fixedly connected to a lead screw 13. The outer surface of the lead screw 13 is rotatably connected to the top plate 11. A slider 14 is threadedly connected to the outer surface of the lead screw 13. The outer surface of the slider 14 is slidably connected to the top plate 11. The long groove provided on the top plate 11 limits the slider 14, making the sliding of the slider 14 more stable. A rotating motor 15 is fixedly connected to the outer surface of the slider 14. The output end of the rotating motor 15 is fixedly connected to a grinding machine 16. The grinding machine 16 is a suspended grinding machine fixedly installed on the surface of the slider 14. As an existing technology, the grinding machine 16 includes a base and a grinding wheel. The grinding wheel is installed on the base through a main shaft. The grinding wheel required for burr treatment is selected for installation. The rotating motor 15 drives the grinding wheel to rotate to grind the burrs. The number of grinding machines 16 is two and they are distributed left and right. The outer surface of the grinding machine 16 is rotatably connected to the slider 14. A suction fan 17 is fixedly connected to the outer surface of the bracket 1. The input end of the suction fan 17 is fixedly connected to an air duct 18. One end of the air duct 18 away from the suction fan 17 is fixedly connected to the bottom plate 4. The upper surface of the air duct 18 is movably connected to a metal mesh frame 19. The inner surface of the bottom plate 4 is movably connected to a metal mesh frame 19. A limiting block 20 is fixedly connected to the inner surface of the metal mesh frame 19. The upper surface of the limiting block 20 is movably connected to a metal mesh plate 12. The outer surface of the metal mesh plate 12 is movably connected to the metal mesh frame 19. The linear motor 2, the rotating motor 15, the double-headed motor 10, and the suction fan 17 are all electrically connected to an external power source. While the double-headed motor 10 drives the two grinding machines 16 to perform double-sided grinding to improve the effect, the suction fan 17 collects the burr debris through the air duct 18 under the isolation of the metal mesh frame 19, and prevents the debris from entering the air duct 18 to eliminate the blockage hazard. And the metal mesh frame 19 can be directly taken out after moving the sliding plate 6 to process or reprocess the debris. The operation is simple. During the sliding of the sliding plate 6, the second slide rail 9 is driven to move on the surface of the metal mesh plate 12 to push the debris into the metal mesh frame 19 to clean the working area.

[0027] Working principle: Place the plastic product between the clamping blocks 8. The clamping blocks 8 are made of relatively soft rubber and adapt to the outer surface of the plastic product as force is applied. Rotate the threaded rod 7, and the clamping blocks 8 perform linear forward and backward movements under the limitation of the second slide rail 9 to clamp the plastic product. Slide the sliding plate 6 in the chute 5 to adjust the left and right positions of the clamped plastic product. According to the grinding height, operate the linear motor 2 to drive the bottom plate 4 to move up and down. The bottom plate 4 drives the sliding plate 6 to move up and down. The sliding plate 6 drives the clamping blocks 8 to move up and down through the threaded rod 7 to adjust the grinding height of the plastic product. Operate the double-headed motor 10 to drive the lead screw 13 to rotate. The slider 14 moves linearly left and right through the threaded transmission of the lead screw 13, and the grinding machine 16 moves to the symmetrical burrs of the plastic product. Operate the rotating motor 15 to drive the grinding machine 16 to rotate, and the excess burrs are ground into particles and fall onto the surface of the metal mesh plate 12 and into the metal mesh frame 19. The exhaust fan 17 drives the air duct 18 to suck the particles in the direction of the air duct 18, and they are intercepted and retained by the metal mesh frame 19. The aperture of the metal mesh frame 19 is smaller than that of the metal mesh plate 12. The metal mesh plate 12 can be placed on the limit block 20, and the metal mesh frame 19 can be taken out from the bottom plate 4 to process the particles.
