Description
Technical field
The utility model relates to tablet press machine, specifically is the punching mechanism of rotary tablet machine.
Background technology
Tablet press machine is a kind of machinery that dryness graininess or powder material is pressed into tablet through mould; Along with continuous progress in science and technology, tablet press machine also constantly develops and improves, and the production of tablet and application have obtained development rapidly; Become clinical practice one of pharmaceutical dosage form the most widely at present; In the preparation production of countries in the world, all accounted for critical role, and for the production of tablet, tablet press machine is the most key and important equipment.
Rotary tablet machine is to use maximum tablet press machines in the tablet manufacturing, and it is a kind of equipment of continued operation.Existing rotary tablet machine in the stamping process down that runs well, between upper plunger and the last punching, all be prone to fall into dust between lower plunger and the following punching, can be and fall into dust, so need frequently clear up to the operation generation resistance of upper plunger and lower plunger.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of punching mechanism of the rotary tablet machine that in punching course, can intercept the dust in gap between entering upper plunger and the last punching and the gap between lower plunger and the following punching is provided.
The purpose of the utility model mainly realizes by the following technical programs: the punching mechanism of rotary tablet machine, comprise main shaft, go up dash dish, in dash dish, down towards dish, upper plunger, middle mould and lower plunger, said go up to dash dish and dash dish down all be connected with main shaft; Dash in the dish during mould is nested in said; In mould the endoporus that runs through its upper and lower end face is arranged, saidly go up to dash the top that dish dashes dish in being arranged on, go up dash dish be provided with middle mould in the corresponding last punching in hole site; Said upper plunger passes punching; Be arranged with first dust board on the upper plunger, first dust board last dash dish and in dash between the dish, and form interference fit between first dust board and the upper plunger; , dish dashes the below of coiling in being arranged under said; Dash down dish be provided with middle mould in the corresponding following punching in hole site; Said lower plunger passes down punching, and the lower ending opening of mould endoporus in the endoporus of mould and in the sealing was arranged with second dust board during the upper end of lower plunger embedded on the lower plunger; Second dust board in dash dish and dash between the dish down, and form interference fit between second dust board and the lower plunger.The utility model is when work, and powder filler or graininess spice press down through upper plunger in the endoporus of middle mould, and particle in the middle mould endoporus or Powdered spice form tablet.
The lower end of said upper plunger and the upper end of lower plunger are equipped with drift, and said lower plunger is through the lower ending opening of mould endoporus in the drift sealing.
The drift of said upper plunger and lower plunger is processed by carbide alloy.
Compared with prior art; The utlity model has following advantage: the utility model go up to dash dish with in dash and be provided with first dust board that is set on the upper plunger between coiling; In dash dish and be provided with second dust board that is set on the lower plunger between coiling with dashing down, in punching course, first dust board can intercept the dust that gets in the gap between punching and the upper plunger; And second dust board can intercept the dust that gets into down in the gap between punching and the lower plunger; So, the utility model can reduce dust and fill gap and the loading in the gap between lower plunger and the following punching between upper plunger and the last punching, so the frequency that can reduce to clear up dust.
Description of drawings
Fig. 1 is the half section structural representation of the utility model embodiment.
The pairing name of Reference numeral is called in the accompanying drawing: 1, main shaft, 2, go up and dash dish, 3, in dash dish, 4, dash dish down, 5, lower plunger, 6, first dust board, 7, second dust board, 8, middle mould, 9, upper plunger.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment:
As shown in Figure 1, the punching mechanism of rotary tablet machine, comprise main shaft 1, go up to dash dish 2, in dash dish 3, dash dish 4, upper plunger 9, middle mould 8 and lower plunger 5 down; Wherein, go up and dash dish 2 and all be connected towards dish 4 down, dash in the dish 3 during middle mould 8 is nested in main shaft 1; Middle mould 8 has the endoporus that runs through its upper and lower end face; Go up to dash dish 2 and dash the top of dish 3 in being arranged on, and go up dash that dish 2 is provided with and middle mould 8 in the corresponding last punchings in hole site, upper plunger 9 passes punching; The lower end of upper plunger 9 is provided with drift, and the drift of upper plunger 9 preferably adopts carbide alloy to process.Be arranged with on the upper plunger 9 first dust board, 6, the first dust boards 6 last dash dish 2 and in dash between the dish 3, and form interference fit between first dust board 6 and the upper plunger 9.Towards the below of dish 3, be provided with and the 8 interior corresponding following punchings in hole site of middle mould towards dish 4 down in being arranged on towards dish 4 down, lower plunger 5 passes down punching, and the upper end of lower plunger 5 is provided with drift, and the drift of lower plunger 5 also preferably adopts carbide alloy to process.The lower ending opening of mould 8 endoporus in sealing in the endoporus of mould 8 and through drift during the upper end of lower plunger 5 embeds; Be arranged with second dust board 7 on the lower plunger 5; Second dust board 7 in dash dish 3 and dash between the dish 4 down, and form interference fit between second dust board 7 and the lower plunger 5.Because of plastic cement is convenient to draw materials, low price, first dust board 6 and second dust board 7 are plastic cement and process.
