Cleaning device of powder screening machine

Abstract

The invention discloses a cleaning device of a powder screening machine. The cleaning device comprises two supporting blocks, a supporting plate is fixedly connected between the two supporting blocks,guide grooves are correspondingly formed in the two supporting blocks, sliding rods are correspondingly and slidably connected into the guide grooves, lifting devices are arranged at the opposite ends of the two sliding rods, square rods are slidably connected to the lifting devices, connecting plates are fixedly connected between the opposite ends of the square rods, the other end of one slidingrod is fixedly connected with a push plate, the rod is connected with a spring in a sleeved mode, one sides of the supporting blocks are fixedly connected with a flat plate, one side of the flat plate is fixedly connected with a second motor, a spindle of the second motor penetrates through the flat plate to be fixedly connected with a cam, and the end face of the convex face of the cam can tightly abut against the push plate. The cleaning device has the advantages that the cleaning device is mounted on a screening machine, so that each screening line in a screening net is rotated by the cleaning device, and then the screening lines vibrate mutually to achieve the effect of vibrating off medicine particles attached to the screening lines.

Description

technical field [0001] The invention relates to the technical field of screening machine cleaning, in particular to a cleaning device for a powder screening machine. Background technique [0002] The preparation of medicines often requires grinding the medicines into powders before blending, and after the medicines are ground into powders, it is necessary to sieve the medicine powder into a particle size range suitable for blending. In the process of sieving medicines, the sieving net in the medicine powder sieving machine will attach a lot of such medicine powders to the sieving net after sieving a medicine powder, and it needs to be cleaned before the next medicine powder can be sieved. If the next drug granule is screened without cleaning it, the two kinds of drug granules will be mixed together, and the mixing of multiple drug granules may cause the drug to lose its original efficacy. It is very cumbersome to clean the pharmaceutical particles. Each screening line is cr...

Problems solved by technology

In the process of sieving medicines, the sieving net in the medicine powder sieving machine will attach a lot of such medicine powders to the sieving net after sieving a medicine powder, and it needs to be cleaned before the next medicine powder can be sieved. If the next drug granule is sieved without cleaning it, the two kinds of drug granules will be mixed together, and the mixing of multiple drug granules may cause the drug to lose its original efficacy. It is very cumbersome to clean the drug particles. Each screening line is criss-crossed and the spacing is very small. It is very difficult to clean manually, and it is easy to clean up.
