Technical Field
[0001] This utility model relates to the field of pharmaceutical raw material processing technology, specifically a multi-stage pulverizing device for pharmaceutical raw materials. Background Technology
[0002] In pharmaceutical production, a multi-stage pulverizing device for pharmaceutical raw materials is a device that uses a multi-stage crushing structure to gradually pulverize raw materials. It is mainly used to improve pulverization accuracy and uniformity of raw materials. Compared with conventional single-stage pulverizing devices, multi-stage pulverizing devices for pharmaceutical raw materials can gradually refine materials through a multi-stage pulverizing structure (such as two-stage pulverizers connected in series), ensuring that the raw materials are more uniform in subsequent production, thereby improving the quality of pharmaceuticals.
[0003] Currently available multi-stage pulverizing devices for pharmaceutical raw materials typically use a sieve cylinder to sieve the pulverized raw materials during the multi-stage pulverizing process. However, in actual operation, the pulverized raw materials often have irregular shapes (such as strip-shaped or fibrous materials), which can easily cause the sieve cylinder to become clogged. This hinders the smooth feeding of the pulverized raw materials and makes it difficult for the device to quickly discharge the raw materials. Therefore, a multi-stage pulverizing device for pharmaceutical raw materials is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution:
[0019] A multi-stage pulverizing device for pharmaceutical raw materials includes a main pulverizing chamber 1. A sieve cylinder body 4 is fixedly connected to the middle of the inner side of the main pulverizing chamber 1. A side support 5 is fixedly connected to the middle of the right side of the main pulverizing chamber 1. A drive cam 16 is rotatably connected in the gap formed between the side support 5 and the main pulverizing chamber 1. The sieve cylinder body 4 is fixedly connected to the inner side of the main pulverizing chamber 1. A striking protrusion 15 is attached to both the upper and lower end faces of the sieve cylinder body 4. A ring 8 is fixedly connected to the outside of the striking protrusion 15. A connecting rod 7, which is slidably connected to the main pulverizing chamber 1, is fixedly connected between the left and right rings 8. A limiting slide 14 is fixedly connected to the upper right and lower right sides of the main pulverizing chamber 1. A traction bracket 9 is slidably connected to the inner side of the limiting slide 14. A movable guide wheel 10 is rotatably connected in a pre-reserved groove at one end of the traction bracket 9 near the drive cam 16. Side locking blocks 11 are fixedly connected to both the front and rear ends of the traction bracket 9. A limiting bracket 12 is fixedly connected to the bottom of the side locking blocks 11. A spring 13 is sleeved on the outside of the limiting bracket 12.
[0020] An auxiliary crushing sleeve 2 with an internally conductive structure is fixedly connected to the left side of the main crushing chamber 1. A feed hopper 17 with an internally conductive structure is fixedly connected to the top left side of the auxiliary crushing sleeve 2. A support frame 19 is fixedly connected to the lower exterior of the main crushing chamber 1. A discharge hopper 20 with an internally conductive structure is fixedly connected to the bottom of the main crushing chamber 1. The discharge hopper 20 extends downwards through a slot pre-reserved on the top surface of the support frame 19. The feed hopper 17 and discharge hopper 20 serve to feed raw materials into the device and discharge qualified crushed raw materials. A crushing spiral blade 3 is rotatably connected to the middle of the inner side of the auxiliary crushing sleeve 2. A crushing cutter 18 is fixedly connected to the output end of the drive motor 6 on the inner side of the screen cylinder body 4. The left side of the output end of the drive motor 6 is fixedly connected to the right side of the crushing spiral blade 3 via a shaft. The crushing spiral blade 3 and the crushing cutter 18 will... A two-stage crushing structure is formed, which facilitates the efficient crushing of raw materials by the device. The output end of the drive motor 6 is fixedly connected to the drive cam 16. The output end of the drive motor 6 extends through the pre-reserved hole groove on the right side of the main crushing chamber 1 to the inside of the screen cylinder body 4. The side support 5 is U-shaped and serves to support and limit the drive motor 6. The connecting rod 7 and the traction bracket 9 are fixedly connected to each other by a column that is slidably connected to the main crushing chamber 1. The two drive cams 16 are arranged symmetrically above and below each other along the center point of the side support 5. The limiting bracket 12 is T-shaped. One end of the spring 13 is fixedly connected to one end of the side block 11, and the other end of the spring 13 is fixedly connected to one end of the limiting slide 14. When the traction bracket 9 reciprocates, the limiting slide 14 plays a certain guiding and limiting role.
[0021] Workflow: The electrical energy required for the device to start and operate in this utility model comes from an external power source. During startup, the drive motor 6 is primarily started by an external controller. In the process of drug production, this multi-stage raw material pulverizing device is used. With the assistance of the side support 5, support frame 19, and auxiliary pulverizing sleeve 2, an appropriate amount of raw material is fed into the feed hopper 17. Since the device pre-starts the drive motor 6 via the external controller, the drive motor 6 rotates the drive cam 16, pulverizing blades 18, and pulverizing spiral blades 3. Because the raw material is pre-feeded into the auxiliary pulverizing sleeve 2, the device first uses the shearing and crushing force generated by the rotating pulverizing spiral blades 3 to perform primary pulverization of the raw material, while simultaneously conveying it from left to right to the inside of the sieve cylinder body 4. After the raw material is delivered, the device performs secondary pulverization of the raw material through the rotating pulverizing blades 18 inside the sieve cylinder body 4. Simultaneously, the pulverized raw material is sieved through the sieve cylinder body 4. In the process, qualified drug raw materials will pass through the holes and grooves on the surface of the sieve cylinder body 4, slide down, and then be discharged from the inside of the feed hopper 20, thus completing the entire multi-stage pulverization operation. However, when irregularly shaped drug raw materials easily clog the surface of the sieve cylinder body 4 during the pulverization process, the drive cam 16, controlled by the drive motor 6, rotates synchronously. Due to the relative upper and lower positions and the connection of the limiting slide 14, the protrusion of the drive cam 16, when rotated to a certain angle, will... The movable guide wheel 10 or the single movable guide wheel 10 at the lower end applies pressure. After the traction bracket 9 overcomes the rebound force generated by the spring 13 through the side clamp 11 and the limiting bracket 12, it carries multiple slapping protrusions 15 through the connecting rod 7 and the ring bar 8 to perform a reciprocating slapping operation in a way that moves away from the surface holes and grooves of the screen cylinder body 4. This is used in conjunction with the device to slap and clear the screen cylinder body 4 where some holes and grooves are blocked, so as to prevent the raw material from continuously blocking the holes and grooves and causing the screen cylinder body 4 to be unable to perform normal screening operation.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
