Description

Screening transmission device for medicine granule production Technical Field The utility model particularly relates to the technical field of medicine granule screening and conveying, in particular to a screening and conveying device for medicine granule production. Background In the process of producing the medicine particles, the medicine particles are required to be classified and screened according to different particle sizes in order to ensure the quality and curative effect of the medicine, for example, the medicine particles with different specifications can be suitable for patients with different age groups and different illness states, and accurate particle size control is helpful for ensuring the accuracy of medicine dosage so as to improve the curative effect of the medicine; The traditional vibration screening device can have the problems of incomplete screening, screen blockage caused by particles and the like when a large amount of medicine particles are processed, and the screening effect and the production efficiency are affected; Through retrieval, chinese patent publication No. CN202321478682.8 discloses an automatic medicine granule split charging device, which comprises a shell, wherein a first filter plate and a second filter plate are fixedly arranged in the shell, the first filter plate is positioned at the top of the second filter plate and arranged at intervals, a plurality of through holes are formed in the first filter plate and the second filter plate, a rotating shaft is rotatably arranged at the bottom of the inner wall of the shell, a plurality of blades are fixedly arranged on the outer ring of the rotating shaft, the rotating shaft penetrates through the first filter plate and the second filter plate, baffle assemblies are hinged to the bottoms of the shell, the first filter plate and the second filter plate, and medicine outlet grooves are fixedly formed in the outer part of each baffle assembly; The device in above-mentioned patent is when sieving the medicine, drives two blades through the pivot and realizes stirring the medicine on two filter to the realization is filtered out the medicine that falls to the second filter through first with equidimension, is provided with out the medicine groove respectively in the bottom of two filter, at blade pivoted in-process, the medicine grain can block in the hole on the filter, the rotation of rethread blade like this, the condition that probably causes the medicine grain to destroy can not be with the original size of medicine grain, thereby makes the condition that the medicine grain appears defect, the medicine effect of medicine grain can not effectually be guaranteed.
