[0020] Please refer to the attached Figure 1-Figure 2 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] The utility model proposes a medicine crushing mechanism for pharmacy. When using the device, a collection bucket is placed under a discharge pipe, an upper opening of a collection bag is wrapped around the outer side of the discharge pipe, and the upper opening of the collection bag is fixed to prevent medicine powder from flying out during subsequent discharge. The motor 1 is started, the motor 1 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives a group of cutters 1 3 to rotate with the rotating shaft 2 as the center of a circle, the rotating shaft 2 drives a grinding roller 7 to rotate in a grinding chamber 10, a group of cutters 1 3 rotates and cooperates with a group of double-sided cutters 2 4 to crush solid medicines (flakes or particles). Since the distance between the cutters 1 3 and the cutters 2 4 is close, the tablets can be cut and crushed more quickly, thereby improving the crushing efficiency. The qualified small particles fall into the drop chamber 11 through the through hole 1 of the filter plate 6, and the medicine blocks that have not been crushed into small particles continue to be crushed in the crushing chamber 12, thereby avoiding the need for secondary crushing due to incomplete crushing. The disadvantage of crushing is that small particles slide along the feeding cavity 11 into the gap between the grinding cavity 10 and the grinding roller 7. The grinding roller 7 grinds the small particles into powder through a group of grooves. The ground powder falls into the discharge cavity 9 through a group of through holes 2 of the truncated cone filter plate 8. The small particles that have not been thoroughly ground continue to be ground, so that the medicine is ground thoroughly to avoid secondary grinding. The ground powder falls into the collecting bag along the discharge cavity 9 and the discharge pipe. When all the tablets are ground, the motor 1 can be turned off. After standing for a while, the powder floating above the collecting bag falls into the bag, and the collecting bag is removed to avoid the powder at the opening of the collecting bag from flying out when the bag is taken out. The device can crush the medicine into small particles and has the grinding function. It is easy to operate and can be used for multiple purposes, thereby improving work efficiency. In addition, the device can be cleaned, inspected and maintained through the movable door 1 and the movable door 2.
