Detailed description of the invention
For ease of understanding technology contents of the present utility model, just by reference to the accompanying drawings its technical scheme is described further below.
A kind of tablet press machine cooling fin device as shown in Figure 1, comprise the up pressure rail 5 that corresponding upper plunger 1 is arranged, be arranged on the pressure rail 6 of described up pressure rail 5 upper end, spring 7 be set between the lower surface of described pressure rail 6 and the upper surface of described up pressure rail 5 and the compression direction of spring 7 is vertical direction.
As shown in Figure 2, before application the utility model, when telling sheet tablet by external force situation as shown in (a), tablet 4 be subject to that the downward frictional force f of itself and middle mould 3 and lower plunger 2 pairs of tablets 4 act on to lifting force F, F
1and F
2, it is F ﹥ F that each power is closed
1=F
2﹥ f.After application the utility model, pressure rail 6 is subject to through the pressure effect of spring to up pressure rail 5 when telling sheet, upper plunger 1 can not hightail the contact with tablet 4, it can the synchronous vertical displacement of the upper and lower jumper bar 1,2 of basic guarantee, when namely telling sheet tablet 4 by external force situation as shown in (b), tablet 4 is subject to the downward frictional force f of itself and middle mould 3, lower plunger 2 pairs of tablets 4 act on to lifting force F, F
1and F
2and downward thrust F ｀, F that upper plunger 1 pair of tablet 4 acts on
1｀ and F
2｀.Wherein directed force F ｀, F
1｀ and F
2｀ can carry out setting by regulating spring 7 pretightning force and regulate, thus makes tablet stress balance.By application the utility model, dependence upper plunger 1 to the downward active force of tablet 4, realizes the slow releasing of air in tablet 4 when telling sheet, substantially makes tablet 4 external and internal pressure balanced.
Be illustrated in figure 3 a kind of embodiment of the utility model involved pressure rail 6:
Wherein said pressure rail 6 comprises adjustment briquetting 61, connecting portion 62 and pretension volution 63.
Described spring 7 is arranged between the lower surface of described adjustment briquetting 61 and described up pressure rail 5.The upper end of described adjustment briquetting 61 arranges vertically extending column type boss.
