Description

Technical Field

[0001] The present invention relates to the technical field of color paste processing, and in particular to an automatic grinding device for color paste processing. Background Art

[0002] Epoxy resin color paste is typically prepared by mixing epoxy resin and pigment, followed by grinding and dispersing to form a uniform mixture. Other additives may be added during the preparation process to adjust the performance and application of the epoxy resin color paste. During the preparation of epoxy resin color paste, due to the strong adhesion of the color paste, the color paste often adheres to the inner wall of the grinding barrel, making it difficult for the color paste to automatically fall off and be ground. As a result, the color paste adhered to the inner wall of the barrel has a different degree of grinding than the color paste in the barrel. Furthermore, the color paste will precipitate during the grinding process. If the precipitate is not promptly processed, it will affect the quality of the final color paste. Therefore, an automatic grinding device for color paste processing is needed to address the above issues. Summary of the Invention

[0022] The lower scraping mechanism 6 includes a side support plate 66 and a stirring spring 67. A driving convex plate 62 is provided along the circumference of the connecting cylinder 51. The driving convex plate 62 is a wavy structure. The lifting plate 63 is arranged parallel to the fixed cylinder 52 and is slidably connected to the guide block 64 on the side of the fixed cylinder 52. The inner side of the lifting plate 63 is symmetrically connected to the guide wheel 65 for rotation. The two guide wheels 65 are respectively connected to the driving convex plate 62 for rolling.

The scraper 61 is provided at the end of the side support plate 66. The scraper 61 is inclined on the side support plate 66 and has an arc surface 611 on its upper side.

[0024] Specific implementation and principle:

[0025] In actual application of the present invention, epoxy resin and pigment are put into the grinding barrel 2 and mixed together, and then the mounting frame 3 is driven downward by the lifting mechanism 11, and the rotating shaft 4 and the connecting cylinder 51 are inserted into the raw materials in the grinding barrel 2, and the scraper 61 on the side support plate 66 abuts against the inner wall of the grinding barrel 2, and then the rotating shaft 4 is driven to rotate by the driving mechanism 12, and the rotating shaft 4 drives the fixed cylinder 52 and the grinding plate 53 to grind the raw materials. When the rotating shaft 4 rotates, it drives the lifting plate 63 to move along the driving convex plate 62 on the side of the connecting cylinder 51, thereby driving the lifting plate 63 and the side support plate 66 upward. The lifting plate 63 moves downward, and the stirring spring 67 between the side support plate 66 and the guide block 64 is bent, and the raw materials adhering to the inner wall of the grinding barrel 2 are scraped off by the scraper 61, and the grinding barrel 2 and the scraped raw materials are stirred and broken up by the stirring spring 67 that is constantly bent and stretched. In the process of the lifting plate 63 moving up and down, the driving plate 76 drives the swing plate 74 to swing back and forth, and the bottom plate 75 between the swing plates 74 stirs the sediment at the bottom of the color paste, so that the sediment is scraped to the grinding plate 53 for grinding, thereby improving the efficiency of scraping and grinding the raw materials in the grinding barrel 2.

[0026] To sum up, the present application uses the grinding mechanism 5 to finely grind the epoxy resin and pigment raw materials in the grinding barrel 2. During this process, the driving convex plate 62 drives the lifting plate 63 to move up and down, and the scraper 61 effectively scrapes off the raw materials adhering to the inner wall of the grinding barrel 2. At the same time, the stirring spring 67, which is constantly in a bending and stretching state, stirs and breaks up the grinding barrel 2 and the scraped raw materials, and stirs the precipitated color paste through the bottom stirring mechanism 7 and scrapes it towards the grinding plate 53 for grinding, thereby significantly improving the grinding quality of the raw materials in the grinding barrel 2.

[0027] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the present utility invention and technical solution are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
