Description

Technical Field

[0001] The utility model relates to the technical field of drug mixing and stirring, and more specifically, to a chamber-type stirring mill for repeated treatment. Background Art

[0002] Chamber stirring mill is a kind of equipment used for material mixing and fine grinding, commonly used in chemical, food and pharmaceutical industries. It is mainly composed of a closed box (chamber type), a stirring device and a drive system. Drug mixing and stirring refers to the process of mixing two or more drug ingredients in a certain proportion and under certain conditions. This process is crucial to ensure the stability and effectiveness of the drug. Drug mixing and stirring is usually used in the pharmaceutical industry.

[0003] In current technical applications, larger particles of drugs often appear in the process of drug mixing and fine grinding. These large particles need to be further refined through a pulverizing process and then finely ground to achieve the required particle size requirements. However, existing mixing and fine grinding equipment often lacks an integrated design, resulting in cumbersome steps in actual operation, such as first crushing the drug into smaller particles and then fine grinding. This step-by-step process not only increases production time and cost, but also increases the complexity of the operation. Utility Model Content

[0004] In order to overcome the above defects of the prior art, a chamber-type stirring mill with repeated treatment is provided to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

In the existing drug crushing and mixing device, the drug powder often hangs on the inner wall of the mixing box due to the existence of static electricity. At this time, the scraper is driven to rotate by the second servo motor to scrape off the drug powder on the inside of the mixing box, which helps to keep the inner wall of the mixing box clean, prevent powder accumulation, and ensure the uniformity of mixing and product quality.

[0009] Furthermore, a rotation hole is provided in the connecting plate, and a first connecting rotating shaft is rotatably provided at the bottom end of the rotating shaft;

[0010] By means of the above technical solution, the first connecting shaft on the rotating shaft is rotated in the connecting plate, so that the rotation of the rotating shaft can be more stable.

[0011] Furthermore, support shafts are fixedly provided on both sides of the mixing box, and triangular support frames are provided on both sides of the two support shafts;

[0022] 1. The utility model proposes a chamber-type stirring mill for repeated treatment. When in use, different drugs with particles only need to be poured into the stirring box through the discharge port for mixing. The rotating shaft can be driven to rotate by the first servo motor. The coarse cutting knife on the rotating shaft can perform preliminary crushing through a larger gap to reduce the size of the particles. The fine cutting knife can finely cut the drug particles due to the small gap, thereby obtaining a smaller particle size, which is very important for the preparation of drugs requiring fine particles. The connecting plate can be driven to rotate by the second servo motor, and the rolling roller on the connecting plate can roll the drug particles to make them into powder. In the existing drug crushing and mixing device, drug powder often hangs on the inner wall of the stirring box due to the existence of static electricity. At this time, the scraper is driven to rotate by the second servo motor to scrape off the drug powder on the inside of the stirring box, which helps to keep the inner wall of the stirring box clean, prevent powder accumulation, and ensure the uniformity of mixing and product quality. The design of this drug crushing and mixing device embodies the principles of automation and efficient production, and improves the quality and consistency of drug preparation through different crushing methods and automatic cleaning functions.

[0023] 2. The utility model proposes a repeated processing chamber stirring mill, which can drive the stirring chamber to reciprocate through the third servo motor. The medicine with smaller particles can first reach the bottom of the stirring chamber and be cut by the fine cutting knife. The medicine with larger particles will stay in the middle of the stirring chamber and be crushed by the coarse cutting knife. The stirring chamber is driven to reciprocate repeatedly by the third servo motor, so that the stirring and mixing of the medicine powder can be more sufficient. BRIEF DESCRIPTION OF THE DRAWINGS
