Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a Chinese medicine powder grinding and processing device. Background Art

[0002] Grinding Chinese medicinal materials into powder can improve the taste and make them easier to swallow. It can also greatly increase their absorption rate. The grinders currently used to grind medicinal materials use iron knives to chop the medicinal materials. Although this improves efficiency, the iron may react chemically with certain components in the medicinal materials, affecting the efficacy of the medicine and even causing toxic side effects.

[0003] With reference to the patent CN112473954A, a medicine mill for grinding traditional Chinese medicine that can clean the residual medicine powder on the side wall is disclosed. The medicine mill comprises a grinding trough, two bottom support frames, and an extendable grinding wheel mechanism. The two bottom support frames are fixedly mounted on the left and right sides of the bottom of the grinding trough, and the extendable grinding wheel mechanism is arranged on the inner side of the grinding trough; the extendable grinding wheel mechanism comprises two grinding wheel shells, and a plurality of mounting slots are provided on the sides of the two grinding wheel shells that are close to each other. The inner walls of the mounting slots are inlaid with magnetic strips. The present invention is superior to the existing technology and the comparative scheme. The airflow can be transformed by pressure change, and the residual traditional Chinese medicine powder on the side can be easily cleaned. The residual medicine powder on the side wall can be blown off without the need for cleaning by hand or cleaning equipment. The residual medicine powder on the side wall can be processed directly during the grinding process.

[0004] However, through searching the above patents and combining with the usage of traditional medicine grinders, it is found that the current medicine grinders still have the following areas that can be improved:

[0005] First, the medicine mill in the above patent requires manual operation when crushing the medicinal materials, and cannot adopt a mechanical transmission method, which leads to high labor intensity and low work efficiency during the crushing process;

[0006] Secondly, when using a medicine grinder, the medicinal materials will be squeezed to the sides of the grinding wheel and cannot be fully crushed. Some medicinal materials will be squeezed to the side wall surface of the grinding groove, resulting in uneven medicinal powder particles. In addition, some medicinal materials will adhere to the surface of the grinding wheel, resulting in the outer end surface of the grinding wheel unable to fully contact the medicinal materials, thereby reducing the crushing effect of the medicinal materials. Summary of the Invention

The driving motor drives the guide plate to rotate, and the outer end surface of the guide plate is fixedly installed with the second screw. When the second screw rotates, it can drive the stone mill wheel to move back and forth, crushing the medicinal materials inside the grinding trough. Mechanical grinding can reduce the labor of workers, and the block at the front end of the scraper is fitted with the stone mill wheel, so that when the stone mill wheel rotates back and forth inside the grinding trough, the block can remove the medicinal material powder on the surface of the stone mill wheel, thereby ensuring that the outer end surface of the stone mill wheel is clean and tidy, and also improving the grinding effect on the medicinal materials.

At this time, the medicinal materials inside the grinding groove 102 will also move to the right. Conversely, when the stone mill wheel 2 rolls to the left, the fixed plate 1 will also tilt to the left. In this way, during the rolling process of the stone mill wheel 2, the fixed plate 1 will perform a reciprocating oscillating motion, which can promote the flow of medicinal materials inside the grinding groove 102 and improve the grinding effect.

[0068] Specific usage and function of this embodiment: In the present invention, when the fixed plate 1 is placed on the desktop, the gas inside the suction cup 11 can be discharged under the action of the gravity of the fixed plate 1. Under the action of atmospheric pressure, the gripping ability of the suction cup 11 can be improved, and the stability of the cushion block 10 can be improved. After the medicinal materials are crushed, the bottle stopper inside the ventilation pipe 1003 can be taken out. At this time, the external gas will enter the ventilation groove 1002 from the ventilation pipe 1003, and then enter the suction cup 11 through the through hole 1101. At this time, it is convenient for workers to take the fixed plate 1, avoiding the violent disassembly of the suction cup 11, and the fastening block 9 is clamped in the transverse track groove 101.

The driving motor 5 will drive the guide disk 501 to rotate, and the outer end surface of the guide disk 501 is fixedly mounted with the second screw 501 1. When the second screw 5011 rotates, it can drive the stone mill wheel 2 to move back and forth, crushing the medicinal materials inside the grinding groove 102. The stopper 601 at the front end of the scraper 6 fits with the stone mill wheel 2, so that when the stone mill wheel 2 rotates back and forth inside the grinding groove 102, the stopper 601 can remove the medicinal material powder on the surface of the stone mill wheel 2, thereby ensuring that the outer end surface of the stone mill wheel 2 is clean and tidy.
