The grinding machine for pharmaceutical preparations is a device specifically used for grinding and pulverizing pharmaceutical raw materials during the processing of pharmaceutical preparations.

[0003] During the preparation of pharmaceutical preparations, the grinding machine plays an important role. Whether it is tablets, capsules or injections, fine grinding and pulverization of pharmaceutical raw materials are required to ensure the quality and stability of the preparations. The grinding machine for pharmaceutical preparations can pulverize pharmaceutical raw materials into the required particle size to meet the requirements of different pharmaceutical preparations for raw material particle size, uniformity, etc.

In the grinding process of a grinding machine without a pre-filtering function, large particle impurities or materials that do not meet the grinding requirements in the raw materials will directly enter the grinding area. During the contact process of these impurities with the grinding mechanism (such as blades, rollers, etc.), it may exacerbate the wear of the grinding mechanism and shorten its service life. Therefore, in view of the above problems, a grinding machine for pharmaceutical preparations with a pre-filtering function is proposed. Summary of the Utility Model

[0024] The following gives specific embodiments.

[0025] Please refer to Figure 1 - Figure 4, the present utility model provides a grinding machine for pharmaceutical preparations with a pre-filtering function, including a grinding machine body 1; a base 10 is provided at the bottom end of the grinding machine body 1; a feeding cylinder 11 is fixedly connected to the top end of the grinding machine body 1; a filter plate 12 is arranged inside the feeding cylinder 11; a cover body 13 is provided at the top end of the feeding cylinder 11; a servo motor 14 is provided at the top end of the cover body 13; an output end of the servo motor 14 is fixedly connected to a rotating shaft 15; the rotating shaft 15 penetrates through the surface of the cover body 13 and is rotatably connected thereto; a scraping plate 16 is fixedly connected to an end of the rotating shaft 15; a plurality of supporting legs 17 are fixedly connected to the bottom end of the base 10; during operation, the grinding machine body 1 can be supported by the base 10, the feeding cylinder 11 can be connected by the grinding machine body 1, and the base 10 can be supported by the supporting legs 17. When workers need to process materials, then the workers cover the cover body 13 on the top end of the feeding cylinder 11, and then put the materials into the feeding cylinder 11 through the filling port. By operating the servo motor 14, the rotating shaft 15 can be driven to rotate. By rotating the rotating shaft 15, the scraping plate 16 can be driven to spread the materials on the filter plate 12. The materials can be filtered by the filter plate 12. Through this design, not only the operation is simple and convenient, but also the materials can be filtered before the grinding machine processes, so that large particle impurities and materials that do not meet the grinding requirements in the raw materials can be removed, making the raw materials entering the grinding area more pure and uniform. At the same time, the service life of the equipment can be prolonged, and the materials can be spread out for filtering, thus improving the filtering effect.

[0026] Further, as Figure 1 and Figure 2 shown, a plurality of elastic sheets 2 are fixedly connected to the side wall of the feeding cylinder 11; elastic rods 21 are symmetrically fixedly connected to the side wall of the rotating shaft 15; a elastic ball 22 is fixedly connected to an end of the elastic rod 21; during operation, the elastic sheets 2 can be supported by the feeding cylinder 11, and the elastic ball 22 can be connected by the elastic rod 21. When pre-filtering the materials, by rotating the rotating shaft 15, the elastic rod 21 can be driven to rotate. By the elastic rod 21, the elastic ball 22 can be driven to rotate. While the elastic ball 22 is rotating, the elastic sheet 2 can be knocked. By knocking the elastic sheet 2, a shock force can be generated. Through the shock force, the materials on the filter plate 12 can be evenly pushed away. Through this design, the elastic sheet 2 can be knocked to generate a shock force, and through the shock force, the materials on the filter plate 12 can be evenly spread out, thus reducing the phenomenon of blockage of the filter plate 12.

[0027] Further, as Figure 2 and Figure 3As shown in the figure, positioning grooves 3 are symmetrically formed at the top end of the feeding cylinder 11; a first magnet 31 is fixedly connected to the inner side of the positioning groove 3; second magnets 32 are symmetrically fixedly connected to the bottom end of the cover body 13; the second magnets 32 are magnetically connected to the first magnets 31; during operation, when the staff installs the cover body 13 and the feeding cylinder 11 together, when the first magnet 31 approaches the second magnet 32, the second magnet 32 can be inserted into the positioning groove 3 to be connected to the first magnet 31. Through this design, when the staff installs the cover body 13, it can play a role in rapid positioning, thus facilitating the staff to install the cover body 13.

[0028] Furthermore, as Figure 4 shown, slots 4 are symmetrically fixedly connected to the side wall of the feeding cylinder 11; a plug 41 is slidably connected to the inner side of the slot 4; the plug 41 is fixedly connected to the side wall of the filter plate 12; during operation, when the staff takes out the plug 41 from the slot 4, the filter plate 12 can be disassembled, and when the staff inserts the plug 41 into the slot 4, the filter plate 12 can be installed. Through this design, it is convenient for the staff to install and disassemble the filter plate 12, thus facilitating the staff to replace the filter plate 12 later.

[0029] Furthermore, as Figure 4 shown, fixing rods 5 are symmetrically fixedly connected to the side wall of the slot 4; a limiting plate 51 is fixedly connected to the side wall of the fixing rod 5; the limiting plate 51 is inclined; during operation, the fixing rod 5 can support the limiting plate 51, and the limiting plate 51 can play a limiting role. Through this design, it can play a limiting role, thus facilitating the staff to insert the plug 41 into the slot 4.

[0030] Furthermore, as Figure 2 shown, an anti-slip pad 6 is provided at the bottom end of the leg 17; the anti-slip pad 6 is adhesively connected to the leg 17; during operation, the anti-slip pad 6 can increase the friction with the ground. Through this design, it can increase the friction with the ground, thus improving the stability of the equipment during operation.

[0031] Furthermore, as Figure 2 shown, a rubber pad 7 is provided on the side wall of the elastic ball 22; the rubber pad 7 is adhesively connected to the elastic ball 22; during operation, the rubber pad 7 can play a protective role. Through this design, when the elastic ball 22 strikes, it can play a protective role, thus reducing damage to the elastic piece 2.

[0032] Working principle: The base 10 can support the grinding machine body 1. The grinding machine body 1 can be connected to the feeding cylinder 11. The legs 17 can support the base 10. When the staff needs to process materials, the staff covers the cover 13 on the top of the feeding cylinder 11, and then puts the materials into the feeding cylinder 11 through the filling port. The servo motor 14 runs, which can drive the rotating shaft 15 to rotate. The rotating shaft 15 rotates, which can drive the scraper 16 to spread the materials on the filter plate 12. The filter plate 12 can filter the materials. The feeding cylinder 11 can support the elastic sheet 2. The elastic rod 21 can be connected to the elastic ball 22. When pre-filtering the materials, the rotating shaft 15 rotates, which can drive the elastic rod 21 to rotate. The elastic rod 21 can drive the elastic ball 22 to rotate. When the elastic ball 22 rotates, it can strike the elastic sheet 2. By striking the elastic sheet 2, a shock force can be generated. Through the shock force, the materials on the filter plate 12 can be evenly pushed away. When the staff installs the cover 13 and the feeding cylinder 11 together, when the first magnetic block 31 and the second magnetic block 32 are close, the second magnetic block 32 can be inserted into the positioning groove 3 to connect with the first magnetic block 31. When the staff takes out the insert block 41 from the slot 4, the filter plate 12 can be disassembled. When the staff inserts the insert block 41 into the slot 4, the filter plate 12 can be installed. The fixed rod 5 can support the limiting plate 51. The limiting plate 51 can play a limiting role. The anti-slip pad 6 can increase the friction with the ground. The rubber pad 7 can play a protective role.
