[0023] See also Figure 1-4 The utility model provides a new type of pulverizing equipment technical solution for the production of pharmaceutical excipients:

[0024] A novel pulverizing device for producing pharmaceutical excipients comprises a pulverizing box 1, the inner wall of which is rotatably connected to two pulverizing rollers 2, the two pulverizing rollers 2 can rotate towards each other to pulverize the excipients, a pulverizing motor 3 is fixedly connected to one side of the pulverizing box 1, the output end of the pulverizing motor 3 passes through the inner wall of the pulverizing box 1 and is fixedly connected to the pulverizing roller 2, the inner wall of the pulverizing box 1 is respectively provided with two groups of brushes 4 corresponding to the pulverizing rollers 2, the brush 4 comprises a mounting seat 41 arranged on the inner wall of the pulverizing box 1, the surface of the mounting seat 41 is fixedly connected with bristles 42, the bristles 42 are fitted with the pulverizing roller 2 to brush off the excipients attached to the surface of the pulverizing roller 2, by providing the brush 4, when the two pulverizing rollers 2 rotate to pulverize the excipients, the bristles 42 will brush off the excipients attached to the surface of the pulverizing roller 2, thereby reducing waste, and the two pulverizing rollers 2 are driven to rotate towards each other to pulverize the excipients by the output end of the pulverizing motor 3.

[0025] The inner wall of the crushing box 1 is fixedly connected with a box cover 5, and the upper surface of the box cover 5 is fixedly connected with a feed hopper 6. The feed hopper 6 is connected to the crushing box 1, and the feed hopper 6 corresponds to the position between the two crushing rollers 2. By setting the feed hopper 6, the auxiliary material is put between the two crushing rollers 2 for crushing.

[0026] The inner bottom wall of the crushing box 1 is respectively formed with two inclined discharge surfaces 7, and a discharge port 8 is formed between the two discharge surfaces 7. The lower surface of the crushing box 1 is fixedly connected with a supporting leg 9. By setting the discharge surface 7 and the discharge port 8, the auxiliary materials that meet the particle size standards after crushing can be discharged.

[0027] The inner wall of the crushing box 1 is rotatably connected to a rotating shaft 10, the surface of the rotating shaft 10 is fixedly connected to a mounting frame 11, the inner wall of the mounting frame 11 is fixedly connected to a screen 12, a discharge port 13 is opened on the front of the crushing box 1, the mounting frame 11 is overlapped on the inner bottom wall of the discharge port 13, and the mounting frame 11 is inclined.

[0028] The inner wall of the crushing box 1 is rotatably connected to a transmission shaft 14, and an eccentric block 15 is fixedly connected to the surface of the transmission shaft 14, and the position of the eccentric block 15 corresponds to the installation frame 11. A screening motor 16 is fixedly connected to one side of the crushing box 1, and the output end of the screening motor 16 passes through the inner wall of the crushing box 1 and is fixedly connected to one end of the transmission shaft 14. The transmission shaft 14 drives the eccentric block 15 to rotate and intermittently lift the installation frame 11, and the output end of the screening motor 16 drives the transmission shaft 14 to rotate, thereby driving the eccentric block 15 to rotate, and then intermittently lifts the installation frame 11. Under the action of its own gravity, the installation frame 11 drives the screen 12 to shake up and down, thereby improving the screening efficiency.

[0029] A sliding hole is provided on the front of the mounting seat 41, and a sliding rod 22 is slidably connected to the inner wall of the sliding hole. Both ends of the sliding rod 22 are fixedly connected to a movable plate 17. The front of the movable plate 17 is provided with fine holes corresponding to the bristles 42. The two movable plates 17 are supported by the sliding rod 22. At the same time, the sliding rod 22 can limit the two movable plates 17 to each other to prevent them from being separated from the bristles 42.

[0030] The inner wall of the crushing box 1 is rotatably connected with a rotating shaft 18, and a mounting seat 41 is fixedly connected to the surface of the rotating shaft 18. An adjustment motor 21 is fixedly connected to one side of the crushing box 1, and the output end of the adjustment motor 21 passes through the inner wall of the crushing box 1 and is fixedly connected to the rotating shaft 18. A mounting groove is provided on the inner wall of the crushing box 1, and a strong magnetic block 19 is fixedly connected to the inner wall of the mounting groove. The strong magnetic block 19 is magnetically adsorbed to the movable plate 17, and a guide plate 20 is fixedly connected to the inner wall of the crushing box 1. The rotating shaft 18 is driven to rotate by the output end of the adjustment motor 21, and then the mounting seat 41 is driven to rotate, so that the bristles 42 on the front and rear sides of the mounting seat 41 are swapped, and the bristles 42 with auxiliary material debris attached to the inside are adjusted to the front side. By setting the strong magnetic block 19, suction can be generated on the approaching movable plate 17, so that the movable plate 17 moves forward, and then the auxiliary material debris attached to the bristles 42 on the front side falls off.

[0031] Working principle: When the new type of pulverizing equipment for producing pharmaceutical excipients is used, the user first starts the pulverizing motor 3 and the screening motor 16, and then puts the excipients from the feed hopper 6 between the two pulverizing rollers 2. The output end of the pulverizing motor 3 drives the two pulverizing rollers 2 to rotate in opposite directions to pulverize the input excipients. The pulverized excipients fall on the screen 12. The output end of the screening motor 16 drives the transmission shaft 14 to rotate, and the transmission shaft 14 drives the eccentric block 15 to rotate. The eccentric block 15 intermittently lifts the installation frame 11. Under the action of its own gravity, the installation frame 11 drives the screen 12 to shake up and down, thereby improving the screening efficiency. The excipients falling from the screen 12 are discharged through the discharge port 8. Excipients with too large particle sizes are discharged through the discharge port 8. The material is discharged from the discharge port 13. During this process, the bristles 42 will brush off the auxiliary materials attached to the surface of the crushing roller 2 to reduce waste. When the bristles 42 need to be cleaned, the adjustment motor 21 is started, and the output end of the adjustment motor 21 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the mounting seat 41 to rotate, so that the bristles 42 on the front and rear sides of the mounting seat 41 are swapped, and the bristles 42 with auxiliary material debris attached inside are adjusted to the front side. The strong magnetic block 19 can generate suction on the nearby moving plate 17, so that the moving plate 17 moves forward, and the auxiliary material debris attached to the bristles 42 on the front side falls off, so that the new pulverizing equipment for the production of pharmaceutical excipients has the effect of reducing the waste of auxiliary materials.
