Upward rotation type tablet screening machine for tablets

Abstract

The invention relates to the technical field of pharmacy, and discloses an upward rotation type tablet screening machine for tablets. The upward rotation type tablet screening machine comprises a tablet screening machine shell, a main shaft guide rail is connected to the inner bottom end of the tablet screening machine shell, and a dust collection pipeline is connected to one side of the bottom end of the tablet screening machine shell. In the working process of the dust collection pipeline, the internal air pressure of an annular air bag is reduced, the inner side wall of the annular air bag contracts and moves outwards to expand the internal diameter of the annular air bag, in the non-working process of the dust collection pipeline, the internal air pressure of the annular air bag is recovered, and the inner side wall of the annular air bag protrudes and moves inwards to reduce the internal diameter of the annular air bag, so that the inner side wall of the annular air bag pulls and extrudes caked powder attached to the surface during protruding contraction movement, the caked powder is extruded into powder, the extruded powder is guided by the surface of the protruding annular air bag to fall into an inner hole of an annular air bag of a lower-layer screen body group, the powder continuously falls to the bottom end of the tablet screening machine shell through the inner side of the annular air bag, and screening holes are prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a top-rotating screener for tablets. Background technique [0002] During the production process of the tablets, the pressed tablets are put into the tablet sieve machine. By using the electromagnet oscillation principle, the horizontally vibrating sieve body and the spiral vertical guide rail are controlled to enter the tablets from the bottom and exit the tablet outlet. In this way, the tablets are continuously conveyed from bottom to top, and the bottom of the sieve machine is connected to the vacuum cleaner pipe to suck out the sieved drug dust, avoiding the sealing problem of the aluminum-plastic blister caused by too much dust in the later internal packaging process, More effective equipment for removing powder from tablet surfaces. [0003] In the use of the tablet sieve machine, the tablet is above the sieve body, and the powder on the surface of the tablet is sieved ou...
