Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, specifically to a color mixing device for sealing ring processing. Background Technology

[0002] A sealing ring is a ring-shaped part used for sealing, usually made of materials such as rubber, plastic, and metal, and has good elasticity and wear resistance. Color mixing is often required during the processing of sealing rings because different customers have different requirements for the color of the sealing rings. This may be to maintain color consistency with matching components, or based on considerations such as the overall product design style and brand image, and specific colors may be specified. Color mixing also makes the surface color of the sealing ring uniform and aesthetically pleasing, improving its visual effect.

[0003] When mixing colors, color powder is typically added to the inside of the mixing tank. This color powder has excellent coloring properties and can be evenly dispersed within the sealing ring material. However, color powder is usually in the form of fine particles. If not handled properly during pouring, stirring, or addition, it can easily be stirred up by airflow, forming dust. This not only affects the workshop environment but also causes color powder to adhere to the upper inner wall of the mixing tank, resulting in material waste. Furthermore, controlling the amount of color powder added during the initial mixing process is difficult. Excessive color powder added to the base materials in the early stages of mixing can easily clump together, making it difficult to disperse evenly and affecting the uniformity of the color mixture.

The color mixing cylinder 7 is equipped with a stirring mechanism inside. A concave plate 3 is fixedly connected to the upper edge of the outer wall of the color mixing cylinder 7. A box body 2 is fixedly connected to the end of the concave plate 3 away from the color mixing cylinder 7. A box cover 1 is hinged to the upper end of the box body 2. A discharge pipe 4 is connected to the lower end of the box body 2. A telescopic feeding mechanism is provided between the lower end of the discharge pipe 4 and the box body 2. Baffles 22 are fixedly connected to both sides inside the discharge pipe 4. A cylinder body 21 is fitted between the two baffles 22. Material grooves 23 are symmetrically opened on the outer wall of the cylinder body 21. An adjustment mechanism is provided between the two material grooves 23 and the cylinder body 21. A second motor 17 is fixedly installed at the rear end of the discharge pipe 4. The output shaft of the second motor 17 movably passes through the inner wall of the rear end of the discharge pipe 4. The output shaft end of the second motor 17 is fixedly connected to the rear end of the cylinder body 21.

[0023] The stirring mechanism includes a support plate 11, which is fixedly connected to the upper edge of the inner wall of the mixing cylinder 7. A motor 12 is fixedly installed at the upper end of the support plate 11. The output shaft of the motor 12 passes through the support plate 11, and a stirring rod 14 is fixedly connected to the end of the output shaft of the motor 12.

[0024] The telescopic feeding mechanism includes a square plate 13, which is fixedly sleeved on the lower edge of the outer wall of the discharge pipe 4. A corrugated hose 5 is fixedly connected to the lower end of the square plate 13, and an annular cover 6 is fixedly connected to the lower end of the corrugated hose 5. A telescopic component is provided between the annular cover 6 and the box 2.

[0025] The telescopic component includes an electric push rod 15, which is fixedly installed on one side wall of the housing 2. A connecting block 16 is fixedly connected to the telescopic shaft end of the electric push rod 15, and one end of the connecting block 16 is fixedly connected to the outer wall of the annular cover 6.

[0026] The adjusting mechanism includes two baffles 18 and two slides 26. The two baffles 18 are respectively fitted into the middle of the inner wall of the two material troughs 23. The corresponding wall surfaces of the two baffles 18 are symmetrically connected to connecting rods 27. The two slides 26 are respectively opened on the inner walls of the two material troughs 23 that are close to each other. The two connecting rods 27 located above and the two connecting rods 27 located below are respectively slidably engaged with the two slides 26. Each pair of adjacent connecting rods 27 is rotatably connected to a threaded sleeve 25. The inner walls of the two threaded sleeves 25 are threadedly connected to a double-ended screw 28. The rear end of the double-ended screw 28 is rotatably connected to the rear end of the inner part of the cylinder 21. The front end of the double-ended screw 28 is provided with a rotating part.

[0027] The rotating component includes a rotating shaft 19, which is fixedly connected to the front end of the bidirectional lead screw 28. The front end of the rotating shaft 19 extends through the front end of the cylinder 21, and a rotating block 20 is fixedly connected to the front end of the rotating shaft 19. Specifically, rotating the rotating block 20 can drive the rotating shaft 19 to rotate, and the rotating shaft 19 can drive the bidirectional lead screw 28 to rotate.

[0028] The adjustment mechanism also includes two rubber rings 24, which are fixedly connected to the front and rear ends of the cylinder 21 respectively. The inner walls of the two rubber rings 24 are tightly fitted with the outer wall of the double-acting screw 28. Specifically, the double-acting screw 28 can maintain a certain fixed state after rotation due to the friction between the two rubber rings 24 and the double-acting screw 28.

[0029] The inner wall of the color mixing cylinder 7 is provided with an annular groove 10; specifically, the height of the material fed into the color mixing cylinder 7 does not exceed the height of the annular groove 10.

[0030] Working principle: Color powder is stored inside the box 2. Color powder is stored between the upper material trough 23 and the upper end face of the upper baffle 18. A small amount of color powder is also stored between the upper material trough 23 and the upper baffle 18 on the cylinder 21. After the base material of the sealing ring is put into the mixing cylinder 7, the motor 12 is started. The motor 12 can drive the stirring rod 14 to rotate, thereby stirring the base material of the sealing ring.

[0031] Then, motor 21 is started, which drives cylinder 21 to rotate in discharge pipe 4. Cylinder 21 also rotates between two baffles 22. Cylinder 21 also drives the two material troughs 23 and the two baffles 18 and other connected components to rotate together. When the material trough 23 and baffle 18, which were originally in the upper position, rotate to face downwards, the color powder will fall into the mixing cylinder 7 along the corrugated hose 5 and the annular cover 6. At this time, the material trough 23 and baffle 18, which were originally in the lower position, will rotate to face downwards and collect the color powder. In this way, as cylinder 21 continues to rotate, the color powder will be intermittently added to the mixing cylinder 7, and the amount added each time is small, so as to facilitate the control of the amount of material added. This avoids the addition of too much color powder to the base raw material during the processing of the sealing ring and in the early stage of color mixing, avoids agglomeration, and improves the uniformity of color mixing.

[0032] After the initial mixing phase is complete, motor 17 is turned off to stop the rotation of cylinder 21. Then, the bidirectional lead screw 28 is rotated by the rotating component. The bidirectional lead screw 28 can drive the two screw sleeves 25 to move away from each other. Each screw sleeve 25 will drive the two connecting rods 27 connected to it to rotate together in opposite directions. Then, the two baffles 18 will move closer to each other and slide towards the center of cylinder 21 in their respective material troughs 23 until the two baffles 18 contact the wall of the two material troughs 23 closest to the center of cylinder 21. Then, the bidirectional lead screw 28 stops rotating. At this time, the space formed between the adjacent material troughs 23 and the baffles 18 will become larger. Then, motor 17 is restarted to drive cylinder 21 to rotate. As described above, the color powder will continue to be intermittently fed into the mixing cylinder 7, and the amount added each time will increase to improve the feeding efficiency.

[0033] By setting up the corrugated hose 5 and the annular cover 6, the scattering of color powder during feeding can be reduced. By activating the electric push rod 15, the electric push rod 15 will drive the connecting block 16 to move down or up. The connecting block 16 will drive the annular cover 6 to move down or up. The annular cover 6 will stretch and compress the corrugated hose 5, causing the corrugated hose 5 to lengthen or shorten. This allows the height of the annular cover 6 to be adjusted so that it is always close to the surface of the material in the mixing cylinder 7. The color powder is less likely to scatter when feeding according to the change in the height of the material in the mixing cylinder 7. It has good adaptability. The color powder will fall directly into the material in the mixing cylinder 7 for rapid mixing. It also avoids the color powder from scattering and adhering to the upper part of the inner wall of the mixing cylinder 7, thus avoiding material waste.
