Description

Technical Field

[0001] This utility model belongs to the technical field of enamel processing and polishing equipment, specifically a polishing device for processing enamel decals. Background Technology

[0002] Polishing enamel decals is a key process for enhancing the surface texture of enamel products after decoration. It mainly targets the enamel surface after the decals have been transferred and fired, removing imperfections and optimizing gloss through physical or chemical methods. Physical polishing often uses wool wheels or cloth wheels with polishing paste to eliminate edge marks and minor scratches of the decals through low-speed grinding, giving enamel products both pattern clarity and a mirror / matte finish.

[0003] The existing polishing equipment for enamel decal processing still has the following shortcomings: When polishing existing enamel decals, workers usually need to hold the polishing device to polish the surface of the enamel product. Holding the polishing device for a long time can easily cause fatigue in the worker's arms, which not only reduces polishing efficiency, but may also cause wear on the edges of the decal pattern and inconsistent gloss due to uneven force, affecting the stability of product quality.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-8 As shown, this utility model provides a technical solution: A polishing device for processing enamel decals includes an operating table 1, a vertical plate 2 fixedly connected to the top of the operating table 1, a circular shell 3 rotatably connected to the vertical plate 2, a clamping assembly provided on the circular shell 3, a first pulley 4 coaxially fixedly connected to the outer periphery of the circular shell 3, a protective cover 5 fixedly connected to one side of the vertical plate 2, a driving assembly provided on the protective cover 5, a movable plate 6 provided at the bottom of the protective cover 5, a pair of guide rails 7 fixedly connected to the bottom of the protective cover 5, a slider 8 slidably connected to each guide rail 7, the bottom of the slider 8 fixedly connected to the movable plate 6, an electric telescopic rod 9 fixedly connected to the bottom of the movable plate 6, a mounting frame 10 fixedly connected to the output end of the electric telescopic rod 9, and a polishing machine 11 fixedly connected to the bottom of the mounting frame 10. Specifically, the clamping assembly can internally support and clamp the enamel product, keeping it stable. The electric telescopic rod 9 is activated, and its output drives the polishing machine 11 at the bottom of the mounting frame 10 to descend until the polishing disc of the polishing machine 11 contacts the enamel product, ensuring uniform contact force between the polishing disc and the enamel product. This also accommodates enamel products of different sizes. Then, the drive assembly is activated, driving the moving plate 6 to move. The moving plate 6 reciprocates along the guide rail 7 via the slider 8, causing the polishing disc of the polishing machine 11 to reciprocate and polish the enamel product. Simultaneously, the drive assembly can drive the circular housing 3 to rotate on the vertical plate 2 via the first pulley 4. The circular housing 3, through the clamping assembly, drives the enamel product to rotate, ensuring that the surface of the enamel product can uniformly contact the polishing disc of the polishing machine 11, thus improving the polishing quality of the enamel product. The clamping assembly includes a first servo motor 12, which is fixedly connected to one side of the circular housing 3. The output end of the first servo motor 12 passes through the circular housing 3 and is rotatably connected to it. The output end of the first servo motor 12 is coaxially fixedly connected to a rotating shaft 13. A turntable 14 is coaxially fixedly connected to the rotating shaft 13. Multiple arc-shaped transmission grooves 15 are opened on the turntable 14. A connecting ring 16 is rotatably connected to the rotating shaft 13. Multiple guide rods 17 are fixedly connected to the outer periphery of the connecting ring 16. One end of each guide rod 17 is fixedly connected to the circular housing 3. A sliding sleeve 18 is slidably connected to each guide rod 17. A transmission pin 19 is fixedly connected to one side of the sliding sleeve 18. The transmission pin 19 is adapted to the corresponding arc-shaped transmission groove 15. A clamping rod 20 is fixedly connected to the other side of the sliding sleeve 18. One end of the rotating shaft 13 is rotatably connected to the circular housing 3. Specifically, the enamel product is placed over multiple clamping rods 20. The first servo motor 12 is started, and the output end of the first servo motor 12 drives the rotating shaft 13 to rotate. The turntable 14 rotates with the rotating shaft 13 at a certain angle. When the arc-shaped transmission groove 15 on the turntable 14 rotates, it will generate a radial thrust on the sliding sleeve 18 through the corresponding transmission pin 19, causing the sliding sleeve 18 to slide along the guide rod 17. Multiple sliding sleeves 18 move away from the connecting ring 16 at the same time, causing the clamping rods 20 to extend outward at the same time until they are tightly against the inner wall of the enamel product. The first servo motor 12 is equipped with an electromagnetic brake. When the first servo motor 12 stops working or is de-energized, the electromagnetic brake locks the output shaft of the first servo motor 12, so that the clamping rods 20 continuously support and fix the enamel product internally. The drive assembly includes a second servo motor 21, which is fixedly connected to one side of the protective cover 5. The output end of the second servo motor 21 passes through the protective cover 5 and is rotatably connected to it. A reciprocating screw 22 is coaxially fixedly connected to the output end of the second servo motor 21. A nut 23 is threaded onto the reciprocating screw 22. A connecting block 24 is fixedly connected to the outer periphery of the nut 23. A through groove is provided at the bottom of the protective cover 5, which is adapted to the connecting block 24. The bottom of the connecting block 24 is fixedly connected to the moving plate 6. One end of the reciprocating screw 22 passes through the vertical plate 2 and is rotatably connected to it. A second pulley 25 is coaxially fixedly connected to one end of the reciprocating screw 22. A belt is sleeved between the second pulley 25 and the first pulley 4. Specifically, the second servo motor 21 is started, and the output end of the second servo motor 21 drives the reciprocating screw 22 to rotate. The reciprocating screw 22 drives the nut 23 to reciprocate. The nut 23 drives the moving plate 6 to move together through the connecting block 24. At the same time, the second pulley 25 rotates together with the reciprocating screw 22. The second pulley 25 drives the first pulley 4 to rotate through the belt. A pair of tensioning rollers 26 are provided on one side of the upright plate 2; Specifically, the tensioner 26 can prevent belt slippage or excessive tightness and wear, ensuring stable power transmission; The circular shell 3 has multiple guide grooves 27 on one side, each guide groove 27 is adapted to the corresponding clamping rod 20, and the clamping rod 20 is covered with a rubber sleeve 28. Specifically, the guide groove 27 can restrict the clamping rod 20 to move smoothly only in the radial direction, and the rubber sleeve 28 plays a buffering role to prevent hard contact from scratching the enamel product. It can also increase the friction with the inner wall of the enamel product and further improve the clamping stability. A pair of telescopic rods 29 are fixedly connected to the bottom of the movable plate 6, and the bottom of each telescopic rod 29 is fixedly connected to the mounting frame 10; Specifically, the telescopic rod 29 can assist the electric telescopic rod 9 in stabilizing the connection to the mounting frame 10, thereby enhancing the overall structural stability of the mounting frame 10.

[0016] The working principle of this utility model is as follows: The enamel product is placed over multiple clamping rods 20. The first servo motor 12 is started. The output end of the first servo motor 12 drives the rotating shaft 13 to rotate. The turntable 14 rotates with the rotating shaft 13 at a certain angle. When the arc-shaped transmission groove 15 on the turntable 14 rotates, it will generate a radial thrust on the sliding sleeve 18 through the corresponding transmission pin 19, causing the sliding sleeve 18 to slide along the guide rod 17. Multiple sliding sleeves 18 move away from the connecting ring 16 in sync, causing the clamping rods 20 to extend outward in sync until they are tightly against the inner wall of the enamel product. The first servo motor 12 is equipped with an electromagnetic brake. When the first servo motor 12 stops working or is de-energized, the electromagnetic brake locks the output shaft of the first servo motor 12, so that the clamping rods 20 continuously support and fix the enamel product internally. Start the electric telescopic rod 9. The output end of the electric telescopic rod 9 drives the polishing machine 11 at the bottom of the mounting frame 10 to descend until the polishing disc of the polishing machine 11 contacts the enamel product. Then the second servo motor 21 is started. The output end of the second servo motor 21 drives the reciprocating screw 22 to rotate. The reciprocating screw 22 drives the nut 23 to reciprocate. The nut 23 drives the moving plate 6 to move together through the connecting block 24. The moving plate 6 moves back and forth along the guide rail 7 through the slider 8, so that the polishing disc of the polishing machine 11 reciprocates to polish the enamel products. At the same time, the second pulley 25 rotates together with the reciprocating screw 22. The second pulley 25 drives the first pulley 4 to rotate through the belt. The first pulley 4 drives the circular housing 3 to rotate on the vertical plate 2. The circular housing 3 drives the enamel product to rotate through the clamping assembly, so that the surface of the enamel product can evenly contact the polishing disc of the polishing machine 11.
