Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical pulverizer technology, and in particular to a pharmaceutical pulverizer. Background Technology

[0002] Pharmaceutical raw materials, such as traditional Chinese medicinal herbs and crystalline chemicals, often suffer from problems like clumping, fiber entanglement, and uneven particle size. If these materials are directly introduced into subsequent processes such as mixing, granulation, and tableting, it can lead to uneven mixing, difficulties in granulation, and failure to meet the tablet disintegration time requirements. Pre-treating raw materials with a pulverizer can break up material clumps, cut off fiber entanglement, and form a uniformly dispersed granular system, providing qualified raw materials for subsequent processes and reducing rework rates. For example, fibrous materials such as traditional Chinese medicinal herbs like astragalus and licorice need to be pulverized before they can be uniformly mixed with other raw materials to avoid excessive differences in tablet weight due to the presence of fiber bundles. Most existing crushers have a fixed vertical crushing tank structure, with only one set of crushing blades directly driven by a motor inside. The distance between the blades and the bottom of the tank is fixed, and the tank wall is smooth with no turbulence structure. When in use, after the material is put into the crushing tank, it is concentrated and piled up in the central area of ​​the bottom of the tank under the action of gravity. Only the material close to the rotation trajectory of the blades can be cut and crushed, while the material far away from the blades remains in a static state for a long time due to the lack of an active turning mechanism, resulting in the residue of coarse particles. Therefore, the above problems need to be improved. Utility Model Content

Ultimately, this solves the problem of coarse particle residue caused by the fixed crushing tank in existing crushers, improving the uniformity of the crushing effect and the material utilization rate.

[0016] Working Principle: Before using this invention, the grinding tank 1 needs to be cleaned. After cleaning, it should be dried to remove water. Loosen the air plug at the air outlet on the outer wall of the grinding tank 1, open the tank lid and the top cover 4 of the drying chamber, screw on the sealing cover 12 at the air hole 11 on the bottom of the tank lid, and start the air pump 6 on the top of the tank lid and the heating rod 5 in the drying chamber. The air pump 6 delivers airflow into the drying chamber, which is heated by the heating rod 5 to form hot air. This hot air enters the interior of the grinding tank 1 through the air hole 11 to dry the residual moisture on the tank wall and inside the tank. The drying process... The water vapor generated is discharged from the air outlet; after drying, the air pump 6 and heating rod 5 are turned off, the sealing cover 12 is screwed on and the air plug at the air outlet is tightened, and then the material is fed and the can lid is sealed: the material to be crushed is put into the crushing tank 1, the cover 4 on the top of the drying box is closed, the smooth bolt on the fixing block 8 is first passed through the C-shaped block, and the limit nut is tightened to lock it, so as to achieve the initial fixation of the can lid and the crushing tank 1; then the bolts on both sides of the can lid are turned and adjusted so that the lower end of the bolt is aligned with the arc-shaped area of ​​the locking block, and the restoring force of the torsion spring on the hinge seat is used. The clamping block rotates around the shaft, firmly pressing against the lower half of the bolt, further reinforcing the connection between the can lid and the crushing can 1. Then, the first motor inside the swing block and the swing assembly on the base 2 are activated. The first motor drives the crushing blades 7 inside the crushing can 1 to rotate at high speed. At the same time, the electric push rod 9 in the swing assembly drives the sliding block to move back and forth along the guide groove of the guide bar. The sliding block drives the lower end of the connecting plate to swing through the first slider. The moving block 10 at the upper end of the connecting plate slides along the slide groove through the limit block. With the extension and retraction adjustment of the telescopic sleeve plate, the rotating shaft drives the swing block to swing. The arc-shaped telescopic sleeve rods on both sides of the swing block and the damping spring group 3 extend and retract synchronously to buffer and prevent the crushing can 1 from vibrating violently when swinging. During the swinging process, the crushing can 1 changes the gravity landing point of the material, causing the accumulated material to disperse. The crushing blades 7 continuously cut and crush the dispersed material to achieve uniform crushing. After crushing is completed, the first motor and the electric push rod 9 are turned off. The limit nut is loosened and the clamping block is moved to overcome the torsion spring force, releasing the clamping block from the bolt and fixing the can lid. The can lid is then opened and the material is removed. Thus, the device is used successfully.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
