Description

Technical Field

[0001] This application relates to the field of pharmaceutical testing equipment technology, and more specifically, to a pharmaceutical grinding apparatus for pharmaceutical testing. Background Technology

[0002] Drugs refer to substances used to prevent, treat, or diagnose human diseases, purposefully regulate human physiological functions, and have specified indications or therapeutic functions, usage, and dosage. The purpose of drug testing is to prevent substandard drugs from entering the market and to ensure drug safety. Drug testing requires grinding devices, such as a drug grinding device for drug testing as described in Chinese patent application number CN202323655472.4. The device includes a grinding box, a fixed plate on the front of the grinding box, a motor under the fixed plate, two grinding rollers rotating inside the grinding box, a positioning bearing on the back of the grinding box, a lead screw inside the positioning bearing, and a connecting nut threaded to the side of the lead screw. This pharmaceutical grinding device for drug testing, through the arrangement of a lead screw, connecting nut, slider, and brush rod, further avoids excessive drug powder adhering to the surface of the grinding roller during the grinding process. At the same time, the brush rod contacts the grinding roller, causing the fine powder adhering to the surface of the grinding roller to be brushed off. This not only prevents waste of raw materials and cross-contamination between different drug powders during the next grinding, but also improves the grinding effect of the drugs.

[0003] However, the above solution still has certain drawbacks: First, different drugs need to share the same grinding space, and after grinding, they need to be thoroughly cleaned manually before the next batch of drugs can be processed. Only one drug can be processed at a time, which reduces the grinding efficiency. Second, the ground drugs are directly discharged into the receiving box, which makes it inconvenient to complete particle size classification at the same time, resulting in the presence of large particles that do not meet the standards in the powder, thus reducing its practicality. Utility Model Content

The fixed plate is fixedly connected to both sides of the collection box, the second motor is fixedly connected to the fixed plate, the screw is rotatably connected to the fixed plate, and the screw is fixedly connected to the output end of the second motor.

[0016] In the above implementation process, the second motor can drive the screw to rotate, and the rotation of the screw can cause the brush plate to move back and forth.

[0017] In one specific implementation, the brush plate includes a connecting plate and a brush. The connecting plate is threadedly connected to the screw and slidably connected to the collection box. The brush is fixedly connected to one side of the connecting plate and contacts the filter plate.

[0018] In the above process, the brush can be used to push the ground medicine on the filter plate, thereby accelerating the filtration efficiency.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: First, two different types of drugs are placed into two cavities respectively. The first and second grinding rollers are driven by a motor to rotate relative to each other, grinding the drugs in the two cavities respectively. Therefore, two different types of drugs can be ground at the same time, which increases grinding efficiency and meets the needs of simultaneous testing of multiple batches and types of drugs. The ground drugs can be filtered through a filter plate, and the brush plate can be moved back and forth on the filter plate by the driving component, which can speed up the filtration of samples and prevent the filter plate from clogging. Thus, different drugs can be ground at the same time, and it is convenient to filter the ground drugs to prevent the presence of large particles that do not meet the standards in the powder, thereby improving practicality.
