Described straight feeding mechanism 6 is connected with vacuum extractor 61.
Described broken granulating mechanism 5 comprises the breaker 51 of blade type and whole grain device 52, and described whole grain device comprises cylinder and is fixed on the axial blade on cylinder, is provided with board-like sieve outside cylinder.
Described dancer 31 and stationary roll 32 surface are provided with the straight burr of arc, the gas be conducive in pressing process is vented again, described dancer 31 designs for chute type, dancer 31 is floated flexibly under the effect of power-equipment, followability is strong, namely dancer 31 follows adjustment voluntarily with the change of feeding amount size and pressure, ensure that the uniformity of compressing tablet hardness, is conducive to improving yield rate.
Described dancer 31 and stationary roll 32 inner hollow, be connected with cooling device, and prevent tablet press mechanism overheated and destroy the quality of medicine, the import and export mix is built-in, workspace and outside clean area are polluted without leaking may, and be convenient to cleaning.
Described tablet press mechanism 3 outside is provided with transparent cloche 4.
Described producer agency 8 is single-punch tablet press, comprise upper plunger 81, middle mould 82, lower plunger 83, described upper plunger 81 is arranged in above mould 82, and lower plunger 83 is arranged in below mould 82, the bottom of upper plunger 81, the upper end of lower plunger 83 all can insert in mould 82 hole.
Described producer agency 8 bottom is provided with wheel, and wheel is positioned in the middle of slideway 84, when needs cleaning producer agency 8, producer agency 8 can be pushed on one side along slideway, be convenient to cleaning, and reduce the working strength of operating personnel.
Operation principle: the compressing dry granulation machine that the utility model provides, by calomel mercurous chloride through degassed even feeding → precommpression → pre-compression molding → broken whole grain → film-making five steps under the condition not adding auxiliary material, tablet is pressed into after making irregular particle, complete the physical change process from powder to tablet, be specially
1, for material process: dry powder enters funnel 21 through charge door 1, under the effect of hollow vertical screw rod, powder is pushed straight feeding mechanism 6, in this process, portion gas is upwards taken out of through screw rod hollow part by bottom screw rod, and powder can be admitted in horizontal screw bolt feeding port uniformly, ensure screw rod fill full, evenly, not empty, do not block up, and make the density of powder obtain preliminary raising, for the quality of second level feed lays the foundation.Medicinal powder after degassed enters straight feeding mechanism 6, highdensity medicinal powder will be carried force to send into tablet press mechanism 3 under the effect of vacuum extractor 61 and horizontal screw bolt, complete precompressed work, the air content entered in the medicinal powder of tablet press mechanism 3 is reduced to minimum, to ensure the quality of compressing tablet, improve output and yield rate, also make equipment run more steady, reliable; Feeding speed frequency conversion is adjustable.
2, pre-sheeting process: the medicinal powder after degassed has possessed the optimum state before pressure rolling, one is through the precompressed of secondary screw feeding, pressure makes the friction of the medicine and dancer 31 and stationary roll 32 surface entering occlusal area improve, decrease the friction of medicine, increase nip angle, two be degassed after medicine make in pressur rolling forming process equipment run more steady, even intensity in blocks, steady quality, become by dancer 31 cross section to be the friction that the straight burr of camber can further improve medicine and tablet press mechanism with stationary roll 32 surface design, and the gas be conducive in pressing process is vented again, sheet after shaping, through the whole grain of lower operation, pulverization rate obviously declines, ensure that the final mass of product to greatest extent.The speed frequency conversion of running roller is adjustable.
3, whole grain operation: tablet enters broken granulating mechanism 5, under the extruding of blade, is extruded and is broken for granule, satisfactory particle is discharged by board-like sieve.
4, film-making operation: the particle sifted out has stronger mobility, enters producer agency 8, under the effect of upper plunger 81, middle mould 82, lower plunger 83, be pressed into tablet.
Single-punch tablet press work time, its operation principle is prior art, namely lower plunger motion 81 to extreme lower position by charging mechanism to fill material in middle mould 82; When charging mechanism turns on, upper plunger 83 is descending, is shaped by the express material in middle mould 82 an actor's rendering of an operatic tune; After upper plunger 81 enters middle mould 82 to bosom, upper plunger 81 continues up, lower plunger 83 is also up subsequently, and (upper plunger 81 first moves, dynamic after lower plunger 83), after upper plunger 81 leaves middle mould 82 an actor's rendering of an operatic tune, the tablet of extrusion molding is just ejected middle mould 82 an actor's rendering of an operatic tune by lower plunger 83, simultaneously by the rotation of charging mechanism, utilize charging mechanism chassis outer rim to be released by tablet, lower plunger 83 fast movement is to extreme lower position simultaneously, continues next tableting processes.
