A pulverizing device for preparing Chinese medicinal materials, through the cooperation among the second motor, the second rotating rod, the cam, the telescopic rod, the fixed plate, the first sliding rod, the first sliding sleeve, the first supporting rod, the third rotating rod, the first gear, the toothed plate, and the rolling roller, can effectively break up the powder by shaking the processing box up and down, so that the powder is restored to a loose state, which is beneficial to subsequent processing or use. The rolling roller is used to crush and break up the powder blocks on the top of the sieve plate. By crushing and breaking them up, the drug components can be better distributed in the entire powder system. After the lumps are broken up, the various medicinal ingredients can be redistributed evenly, ensuring the accuracy of the dosage and the consistency of the medicinal effect each time it is used.

[0017] 2. A pulverizing device for preparing Chinese medicinal materials, through the cooperation among a connecting sleeve, a connecting rod, a connecting plate, an elastic scraper, a resisting rod, a vertical hole, a second sliding rod, a second sliding sleeve, a first spring, an inclined block, a connecting frame, a fixed rod, a push rod, and a second spring, can push the powder on the top of the sieve plate into the sieve hole through the lateral movement of the elastic scraper to avoid the accumulation of powder on the top of the sieve plate and affecting the feeding, and can push out the powder blocked inside the sieve hole through the movement of the push rod inside the sieve hole to avoid the blockage inside the sieve hole and affect the normal circulation, so that the powder can pass through the sieve hole in time and maintain a stable screening speed, thereby improving the production efficiency of the entire production process.

[0018] 3. The pulverizing device for preparing Chinese medicinal materials, through the cooperation among the fourth rotating rod, the guide plate, the second supporting rod, the threaded groove, the threaded sleeve, the first scraper and the limit plate, can make the Chinese herbal medicine powder evenly slide to the top of the sieve plate through the rotation of the guide plate to avoid the accumulation of materials in a certain place. In this way, the crushed Chinese herbal medicine can be more reasonably distributed in the space at the bottom, which is convenient for the subsequent powder block crushing process, so that each part of the material can be evenly processed, and the powder sticking to the guide plate can be scraped off by the first scraper to avoid powder adhesion, which can ensure that the powder can flow continuously and smoothly along the guide plate and maintain a stable feeding speed.

[0019] 4. This pulverizing device for the preparation of Chinese medicinal materials, through the cooperation between the fourth rotating rod, the guide plate, the second support rod, the threaded groove, the threaded sleeve, the first scraper, and the limit plate, can guide the powder particles through the guide plate. Smaller particles will flow faster along the surface of the guide plate, while larger particles may roll or move slowly on the guide plate due to factors such as gravity. This layering and mixing effect makes the final crushed Chinese herbal medicine product more uniform in particle size distribution. For example, in the production of Chinese medicine preparations, uniform particle size has an important impact on the dissolution rate of the drug, the release of drug efficacy, etc., and can ensure that the quality and performance of each batch of drugs are more stable.

The rotation of the cam 613 can drive the top processing box 2 to shake up and down, thereby driving the powder blocks on the top of the internal screen plate 9 to shake, so that they are initially shaken out. A fixed plate 615 is fixedly connected to the front of the crushing box 1, and a first sliding rod 616 is fixedly connected to the left side of the fixed plate 615. The outer wall of the first sliding rod 616 is movably sleeved with a first sliding sleeve 617. The top of the first sliding sleeve 617 is hinged with a first supporting rod 618. The end of the first supporting rod 618 away from the first sliding sleeve 617 is rotatably connected to the inner wall of the crushing box 1. The back of the first sliding sleeve 617 is rotatably connected to the third rotating rod 619 through a bearing. When the processing box 2 moves upward, it will rotate on the first support rod Under the action of 618, the first sliding sleeve 617 is driven to move laterally on the outer wall of the first sliding rod 616, thereby driving the rolling roller 622 to roll the powder block laterally. The outer wall of the third rotating rod 619 is fixedly connected with the first gear 620, and the front of the crushing box 1 is fixedly connected with a tooth plate 621, the tooth plate 621 and the first gear 620 are meshed with each other, and the outer wall of the third rotating rod 619 is fixedly connected with the rolling roller 622.
