Description
Technical field
The utility model relates to a kind of flour dressing machinery, particularly a kind of machinery of the powder separation that makes the tablet medicine and adhere to.
Background technology
In the prior art, tablet screening machine is to adopt " on go into down " to walk a plurality of individual layer tray type structure of sheet mode.This structure is because sheet, powder be all and move downward, so when the tablet that sieve when the ground floor screen tray fell into second layer screen tray continuation processing, the dust that is sized out in the ground floor also fell to the union dyeing with it of second layer screen tray; Similarly the dust that is sieved out by second layer screen tray is fallen on the tablet of the 3rd layer of screen tray again; So circulation, it is sticking to cause the sheet powder to mix repeatedly inevitably, has reduced the effect of gumming and finishing burr widely, directly influences the processing quality and the production efficiency of tablet screening machine, and when the batch of tablet focused on, it is more undesirable that treatment effect seems.
Chinese patent application 90213502.3 discloses a kind of bugduster, by body, be installed in the vibrator in the underpart space and the base that is located under the body is formed, vibrator is fixed by bolt and body, body is sitting on the base, body comprises housing and movement, and housing is provided with the mouth that is used as medicine, and movement has three layers or three layers with upper sieve plate, on bottom sieve plate, separating plate is housed, makes tablet avoid repeated contamination.The sheet powder mixes sticking problem repeatedly in above-mentioned each layer screen tray but this application does not still solve.
Summary of the invention
It is a kind of simple and reasonable that the purpose of this utility model is to provide, the tablet screening machine that the gumming effect is better and efficient is higher.
To achieve these goals, tablet screening machine of the present utility model comprises screen tray main body and the vibrator that is connected with the screen tray main body; Its design feature is: the screen tray main body is formed by stacking by a plurality of screen tray groups; Described each screen tray group comprises screen tray and next part powder dish, constitutes powder collection cavity between last screen tray and the next part powder dish, constitutes sieve sheet chamber between the adjacent screen tray group, and the adjacent with it sieve sheet chamber in powder collection cavity and below isolates.Herein " isolation " be meant that the dust granules that tablet in the sieve sheet chamber and powder collection cavity are collected is isolated, promptly the powder in the powder collection cavity does not fall into the sieve sheet chamber of below, existing branch mixes the problem of gluing repeatedly in the prior art thereby solved.
Compared with prior art, the utlity model has following positive effect: (1) tablet screening machine of the present utility model is by sieve sheet chamber finishing burr and screening tablet, the dust that is fallen by the timely collection screen of powder collection cavity also carries out the sheet powder and isolates, sticking to prevent that the sheet powder from mixing repeatedly, it is simple and reasonable, is convenient to processing, disassembly and maintenance cleaning; In addition, it also can be applicable to industries such as pharmacy, chemical industry, food and electronics.
