Description

Technical Field

[0001] The invention relates to the technical field of drug raw material grinding, in particular to a drug raw material grinding device capable of gradually adjusting the grinding interval and a grinding method thereof. Background Art

[0002] Grinding of drug raw materials is an important step in the pharmaceutical process. It involves breaking large or hard drug raw materials into smaller and more uniform particles by physical or mechanical methods. This process is crucial for improving the solubility and bioavailability of drugs and subsequent formulation processes. Grinding can increase the surface area of ​​drug particles, thereby increasing their contact area with the solvent and improving the dissolution rate. The fine particles after grinding are more easily absorbed by the body, thereby improving the bioavailability of the drug. At the same time, the ground raw materials are easier to carry out subsequent formulation processes such as mixing, granulation, and tableting.

[0003] However, in traditional pharmaceutical raw material grinding devices, the grinding disk is fixed in position and the grinding distance cannot be adjusted, which makes it impossible to adjust the degree of grinding of the pharmaceutical raw materials. At the same time, some devices need to be shut down to adjust the grinding disk position. There is a problem that the grinding distance cannot be adjusted online when the pharmaceutical raw materials are ground, which makes it difficult to adjust the size of the powder particles after grinding. Therefore, it does not meet the existing needs. In this regard, the present application proposes a pharmaceutical raw material grinding device and a grinding method thereof that can gradually adjust the grinding distance. Summary of the invention

[0004] The object of the present invention is to provide a drug raw material grinding device and a grinding method thereof with gradually adjustable grinding distance, by moving a movable seat toward a fixed seat until the grinding space is in a closed state, and then moving the rotating convex grinding disk toward the fixed seat, so that the convex grinding disk and the concave grinding disk gradually approach each other, thereby gradually reducing the grinding distance, and then grinding the drug raw material inside the grinding space into powder, realizing online adjustment of the grinding distance, improving grinding efficiency, and solving the problems in the prior art.

[0010] A method for grinding a drug material is implemented based on a drug material grinding device capable of gradually adjusting the grinding distance, comprising the following steps: Step 1: The electric telescopic rod drives the movable seat to contact the fixed seat. At this time, the grinding space is closed, and the personnel add the drug raw materials into the grinding space from the feed pipe; Step 2: After the second motor drives the outer convex grinding disc to rotate through the rotating shaft, the first motor drives the screw to rotate forward, so that the adjustment plate drives the positioning block and the outer convex grinding disc to move toward the fixed seat, so that the outer convex grinding disc and the inner concave grinding disc gradually approach each other, and the rotating outer convex grinding disc crushes the drug raw material; Step 3: Close the electric telescopic rod, and the first motor drives the screw to reverse, so that the adjustment plate drives the convex grinding disc and the positioning block away from the fixed seat.

At this time, the grinding space is open, and the drug raw material powder enters the storage chamber from the discharge port. After that, the personnel opens the gate and takes the drug raw material powder out of the storage chamber. The personnel can push the remaining drug raw material powder out of the grinding space by extending the convex grinding disk from the inside of the movable seat, thereby improving the collection rate.

[0019] When the electric telescopic rod 106 moves the movable seat 5 toward the fixed seat 2 until the grinding space 502 is in a closed state, the second motor 602 drives the convex grinding disc 6 to rotate and move toward the fixed seat 2, so that the convex grinding disc 6 and the concave grinding disc 202 gradually approach each other, thereby gradually reducing the grinding distance, and then grinding the drug raw materials inside the grinding space 502 into powder, realizing online adjustment of the grinding distance and further improving the grinding efficiency.

[0020] When the drug raw material is ground, the first motor 103 drives the positioning block 7 and the convex grinding disk 6 away from the fixed seat 2. When the positioning block 7 contacts the baffle 503, the movable seat 5 follows the positioning block 7 to move until the baffle 503 contacts the combining plate 3. At this time, the grinding space 502 is open, and the drug raw material powder enters the storage chamber 4 from the discharge port 101. Then, the personnel opens the gate 401 to take the drug raw material powder out of the storage chamber 4.

As the positioning block 7 moves, when the sealing ring 701 contacts the baffle 503, the movable seat 5 follows the positioning block 7 and moves until the baffle 503 contacts the combining plate 3. At this time, the grinding space 502 is in an open state, and the crushed drug raw materials enter the interior of the storage chamber 4 from the discharge port 101; Step 4: The first motor 103 drives the screw rod 1031 to rotate forward again, and the convex grinding disc 6 extends from the inside of the movable seat 5, so that the convex grinding disc 6 pushes the remaining drug raw material powder out from the inside of the movable seat 5 and enters the inside of the storage chamber 4 from the discharge port 101; Step 5: The first motor 103 drives the screw rod 1031 to reverse again, so that the adjustment plate 704 drives the convex grinding disc 6 back to the inside of the moving seat 5 , and then the personnel opens the gate 401 to take out the drug raw material powder from the inside of the storage chamber 4 .

[0022] Working principle: When the electric telescopic rod 106 moves the movable seat 5 toward the fixed seat 2 until the grinding space 502 is in a closed state, the second motor 602 drives the convex grinding disc 6 to rotate and move toward the fixed seat 2, so that the convex grinding disc 6 and the concave grinding disc 202 gradually approach each other, thereby gradually reducing the grinding distance, and then grinding the drug raw materials inside the grinding space 502 into powder, realizing online adjustment of the grinding distance, thereby improving the grinding efficiency.
