It uses the shear force of the grinding media to break the particles, and its core purpose is to achieve uniform dispersion and stable suspension of color paste particles.

[0003] In existing pigment processing grinding equipment, raw materials are typically poured into the equipment, which grinds and refines them. After filtration and repeated grinding, the pigment processing is complete. During the grinding process, the vibration generated by the equipment raises a large amount of dust. In common grinding equipment, the grinding part and the feeding part are connected by flanges. When vibration occurs, gaps may appear between the flanges, causing dust to overflow. Furthermore, during processing, raw materials may need to be added manually. When adding raw materials, opening the sealing cover may cause a large amount of dust to overflow, which may affect the safety of employees. Utility Model Content

[0004] To overcome the problems of dust overflow caused by vibration during the use of grinding equipment for color paste processing, and the large amount of dust overflowing when adding raw materials, a dust-proof raw material grinding device for color paste processing is proposed.

A motor 15 is installed at the lower end of the fixed plate 12. The output end of the motor 15 passes through the lower end of the fixed plate 12 and is connected to the rotating shaft of the movable plate 4. A lower flange 7 is fixedly connected to the upper opening of the grinding machine 1. An upper flange 6 is fixedly connected to the lower opening of the feed cylinder 2. The lower flange 7 is adapted to the upper flange 6. A fixing ring 9 is fixedly connected to the upper end of the lower flange 7. The outer wall of the fixing ring 9 and the inner wall of the upper flange 6 are threaded. The upper flange 6 is threaded on the outer wall of the fixing ring 9 and fixed to the upper end of the lower flange 7 by bolts.

[0023] By using the sealing cover 10 in conjunction with the movable plate 4, the upper opening of the grinder 1 can be double-sealed. When adding raw materials, the movable plate 4 is closed to prevent dust from overflowing from the grinder 1. The output end of the motor 15 can drive the movable plate 4 to rotate along the slide groove 13. The movable plate 4 can be opened after the sealing cover 10 is closed to allow the raw materials to enter the grinder 1, thus preventing dust from overflowing from the feed cylinder 2 opening and affecting the workers. Furthermore, by using the threaded groove on the outer wall of the fixing ring 9 in conjunction with the thread on the inner wall of the upper flange 6, the upper flange 6 can be limited and fixed. The upper flange 6 can be fixed to the upper end of the lower flange 7 with bolts, which can effectively prevent gaps caused by vibration and reduce the situation of dust overflowing.

[0024] Please see Figures 3-4 In this embodiment, a guide plate 11 is fixedly connected to the inner wall of the feed cylinder 2. The guide plate 11 is located at the upper end of the fixed plate 12 and corresponds one-to-one with the fixed plate 12. In use, the raw material at the lower end of the sealing cover 10 and the upper end of the fixed plate 12 can be guided to the movable plate 4 through the guide plate 11, so as to quickly and easily guide the material into the grinding machine 1. A sealing gasket is fixedly connected to the outer wall of the movable plate 4, and a sealing ring 8 is provided between the upper flange 6 and the lower flange 7. In use, the sealing gasket can improve the sealing performance of the movable plate 4, and the sealing ring 8 can improve the sealing performance between the upper flange 6 and the lower flange 7.

[0025] Please see Figures 5-6 In this embodiment, a support frame 16 is fixedly connected to the outer wall of the grinder 1, and a vacuum cleaner 5 is fixedly connected to the upper end of the support frame 16. During use, the vacuum cleaner 5 can absorb the dust inside the grinder 1 to prevent dust from overflowing. The suction pipe of the vacuum cleaner 5 passes through the outer wall of the grinder 1 and is flush with the inner wall of the grinder 1. A collection tank 17 is installed at the opening of the dust discharge pipe of the vacuum cleaner 5. During use, the dust can be collected through the collection tank 17, which facilitates the recycling of dust.

[0026] Please see Figure 7 In this embodiment, a discharge device 3 is fixedly connected to the lower opening of the grinder 1. Three support rods 18, equidistant from each other around the discharge device 3, are fixedly connected to the outer wall of the discharge device 3. A filter cylinder 19 is fixedly connected to the lower end of the discharge device 3. During use, the grinder 1 can be supported by the support rods 18. The filter cylinder 19 can filter the ground material to improve the grinding quality. An annular groove 20 is opened at the lower end of the filter cylinder 19. A filter screen 21 is installed in the annular groove 20. A sealing cylinder 22 is installed on the lower outer wall of the filter cylinder 19. The sealing cylinder 22 is interference-fitted with the filter cylinder 19. During use, the filter screen 21 can be easily disassembled and replaced by opening threaded grooves on the inner wall of the annular groove 20 and the outer wall of the filter screen 21. The sealing cylinder 22 can ensure the sealing of the lower end of the discharge device 3 and prevent dust from overflowing.

[0027] When working, first, start the grinder 1, open the sealing cover 10, pour the raw material to be ground into the feed cylinder 2, and then close the sealing cover 10. Next, start the motor 15. The output end of the motor 15 drives the movable plate 4 to rotate and fit against the upper end of the fixed plate 12. Then, turn off the motor 15 and wait for all the raw material to fall into the grinder 1. Then, wait for the grinder 1 to finish grinding the raw material and filter it through the discharge device 3. Then, start the vacuum cleaner 5 and wait for the vacuum cleaner 5 to finish adsorbing the dust in the grinder 1. Finally, turn off the grinder 1 and the vacuum cleaner 5, remove the sealing cylinder 22, and you can take out the ground material.

[0028] During the grinding process, the motor 15 can be started. After the motor 15 drives the movable plate 4 to rotate and then closes, the motor 15 is turned off and the sealing cover 10 is opened. The raw materials to be added are poured into the feed cylinder 2. After the sealing cover 10 is closed, the motor 15 is started again. After the motor 15 rotates and the movable plate 4 is opened, the material can enter the grinding machine 1. When the filter screen 21 needs to be replaced, the filter screen 21 can be rotated to remove it. After the new filter screen 21 is aligned with the filter cylinder 19, the filter screen 21 can be rotated to install the filter screen 21 threadedly on the inner wall of the filter cylinder 19. After the work is completed, the collection tank 17 can be removed to recycle the collected dust.

[0029] Through the above steps, the sealing cover 10, together with the movable plate 4, can provide a double seal for the upper opening of the grinder 1. The closing of the movable plate 4 can prevent dust from overflowing from the grinder 1. The output end of the motor 15 can drive the movable plate 4 to rotate along the slide groove 13. After the sealing cover 10 is closed, the movable plate 4 can be opened to allow the raw material to enter the grinder 1, thus preventing dust from overflowing from the opening of the feed cylinder 2 and affecting the workers. The threaded groove on the outer wall of the fixing ring 9, together with the thread on the inner wall of the upper flange 6, can limit and fix the upper flange 6. The upper flange 6 can be fixed to the upper end of the lower flange 7 with bolts. This solves the problem of dust overflowing due to vibration when the grinding device for color paste processing is in use, and the problem of a large amount of dust overflowing when adding raw materials.
