Abstract

The invention discloses a grinding machine for medical medicine, which comprises an upper body and a lower body. The upper body includes a milling cup and an inserting barrel connected to the center of the bottom of the milling cup. Both sides of the inserting barrel are symmetrically provided with locking grooves. The bottom of the powder cup is provided with a shock-absorbing sleeve set around the socket, the powder cup is provided with a mill knife and a mill shaft, the upper end of the mill shaft extends into the mill cup to connect with the mill knife, and the lower end of the mill shaft extends into the In the insertion barrel, the center of the lower body is provided with a connection cavity and a motor from top to bottom. The connection cavity and the insertion barrel are both square and suitable in size. The lower part of the lower body is equipped with a motor, and the drive shaft of the motor extends into the connection cavity. Both sides of the connecting cavity are provided with locking rods, the locking rods and the locking grooves are square and suitable in size, after the upper body is installed on the lower body. The milling cup of the present invention is detachably arranged on the lower body, and can ensure that the milling shaft and the drive shaft are coupled and the axes are coincident, so that the transmission will not vibrate, and the working stability under high-speed milling is further improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a medical drug grinding machine. Background technique [0002] Chinese patent CN108607638A discloses a medical medicine crushing and grinding device. By setting two pressure rollers in the crushing box, the pressure rollers will squeeze the falling solid medicine under the drive of the first motor. The final powdered drug will enter the filter box from the first outlet, and there is a filter plate to screen the drug powder of different particles, and the particle powder that does not meet the requirements will slide down from the filter plate into the first delivery pipeline. The first conveying screw conveys the granular matter into the second conveying pipeline, and the second conveying screw conveys the granule drug to the crushing box for secondary crushing, so that the crushed state of the drug can meet the requirements, and the drug powder that meets the requirements will ...
