[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-6 As shown, this utility model provides a technical solution: a crushing device for producing acetaminophen raw materials, including a support 1 and a housing 2. A feed hopper 3 is provided on the upper surface of the housing 2, and a discharge port 4 is provided on the lower surface of the housing 2. Crushing rollers A5 and B6 are rotatably connected inside the housing 2. A gear A7 is fixedly installed at one end of crushing roller A5, and a gear B8 is fixedly installed at one end of crushing roller B6. A motor A9 is fixedly installed on the side of the housing 2. A screening plate 10 is provided inside the housing 2. A crushing roller 11 is slidably connected to the inner side of the housing 2. An installation plate is fixedly installed on the side of the housing 2. 12. A movable block 13 is slidably connected inside the mounting plate 12. A threaded rod 14 is rotatably connected inside the mounting plate 12. A motor B15 is fixedly installed on the side of the mounting plate 12. A slide rod 16 is fixedly installed inside the mounting plate 12. Gear A7 and gear B8 mesh and drive each other. The output end of motor A9 is fixedly connected to one end of crushing roller A5. Crushing roller 11 is rotatably connected to movable block 13. Movable block 13 is slidably connected to slide rod 16. The output end of motor B15 is fixedly connected to one end of threaded rod 14. Threaded rod 14 is threadedly connected to movable block 13.

[0024] In this embodiment, by setting a screening plate 10 inside the housing 2, the raw materials after preliminary crushing can be screened out, and the raw materials that do not meet the crushing requirements can be screened out. The motor B15 is started to drive the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the moving block 13 and the moving block 13 is slidably connected to the slide rod 16, the moving block 13 can drive the crushing roller 11 to move horizontally, thereby enabling the raw materials that do not meet the crushing requirements to be crushed again, which improves the flexibility and crushing effect of the device.

[0025] Example 2: As Figures 1-6 As shown, a conveying box 17 is fixedly installed at the lower end of the discharge port 4. A rotating rod 18 is rotatably connected inside the conveying box 17. An auger 19 is provided on the surface of the rotating rod 18. A motor C20 is fixedly installed on the side of the conveying box 17. A conveying pipe 21 is provided on the surface of the conveying box 17. The output end of the motor C20 is fixedly connected to one end of the rotating rod 18.

[0026] In this embodiment, a conveying box 17 is set at the lower end of the discharge port 4. The motor C20 drives the rotating rod 18 to rotate, which in turn drives the auger 19 to rotate. The crushed raw materials can be conveyed out through the conveying pipe 21, realizing the automatic conveying of the crushed raw materials, which facilitates the subsequent processes and improves the continuity of the entire production process.

[0027] The working principle of this embodiment is as follows: During operation, the acetaminophen raw material is first added into the housing 2 from the feed hopper 3. The motor A9 is started, and the motor A9 drives the crushing roller A5 to rotate. Due to the meshing transmission between gear A7 and gear B8, the crushing roller B6 rotates synchronously. The raw material is initially crushed under the action of the two crushing rollers rotating in opposite directions. The material after initial crushing falls onto the screening plate 10. The material that meets the particle size requirements passes through the screening plate 10 and falls into the conveying box 17 from the discharge port 4, while the material that does not meet the requirements remains on the screening plate 10. At this time, motor B15 is started, which drives the threaded rod 14 to rotate. Because the threaded rod 14 is threadedly connected to the moving block 13 and the moving block 13 is restricted by the sliding rod 16 and can only slide along the sliding rod 16, the moving block 13 drives the crushing roller 11 connected to it to move horizontally, and crushes the substandard material left on the screening plate 10 again. There is no need for the staff to manually remove the incompletely crushed raw materials and manually add them for secondary crushing, which saves manpower and improves the crushing quality, as well as the flexibility and crushing effect of the device. After secondary crushing, the material that meets the particle size requirements passes through the screening plate 10 and enters the discharge port 4 and then falls into the inside of the conveying box 17. At this time, the motor C20 is started to drive the rotating rod 18 to rotate, which drives the auger 19 to rotate, and the crushed raw materials can be conveyed out through the conveying pipe 21, realizing the automatic conveying of the crushed raw materials, which facilitates the subsequent processes and improves the continuity of the entire production process.

[0028] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
