Abstract
The utility model relates to a tablet press, in particular to an upper punch inner idler-wheel-type press mould of the tablet press. The upper punch inner idler-wheel-type press mould of the tablet press comprises an upper rail guide disc, wherein an annular rail is arranged at the outer circle of the upper rail guide disc. The upper punch inner idler-wheel-type press mould of the tablet press further comprises an upper punch rod, and is characterized by further comprising a movable wheel shaft transversely penetrating the upper punch rod, wherein the left end and the right end of the movable wheel shaft are respectively fixed through a nut, the right end part of the movable wheel shaft is exposed out of the nut, the exposed part of the movable wheel shaft is provided with an idler wheel in a sleeved mode and is fixed through a check ring, the outer circle of the idler wheel is right connected with the annular rail of the upper rail guide disc in a sliding mode, and the idler wheel is perpendicular to the contact surface of the annular rail. Compared with the prior art, due to the smooth contact between the surface of the idler wheel and the surface of the rail, the operation is easy and stable. Frictional resistance of the rail is reduced, the advantages of being stable and free of abrasion of the upper punch press mould are effectively guaranteed, and the work reliability of the upper punch mould is largely increased.
Description
Technical field
The utility model relates to a kind of tablet press machine, specifically a kind of tablet press machine upper punch internal trolley formula pressing mold.
Background technology
Traditional rotary tablet machine, diel all adopts the mode of hanging slide rail to rotate on the compressing tablet, mainly be to hang on the track on the diel to move, this mode can cause and produce wearing and tearing between track and the punch die top, it is in orbit stuck that upper trimming die takes place often, the disadvantage that service life is short, maintenance and production cost are higher.
Summary of the invention
The utility model provides a tablet press machine upper punch internal trolley formula pressing mold in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of tablet press machine upper punch internal trolley formula pressing mold, comprise the rail godet, the cylindrical of last rail godet is provided with circular orbit, also comprise a upper plunger, it is characterized in that: also comprise a free wheel axle that laterally runs through upper plunger, and two ends, the free wheel axle left and right sides adopt nut to fix respectively, wherein the right end portion of free wheel axle exposes to nut, and at the sheathed roller of the exposed parts of free wheel axle and adopt back-up ring to fix, the cylindrical of described roller just in time is slidingly connected with the circular orbit of last rail godet, and the contact-making surface of roller and circular orbit is orthogonal.
The utility model is compared with prior art, adopts idler wheel surface to contact with the smooth of orbital plane, and running is easily stable.Reduced the track friction resistance.Effectively guarantee the advantage of the stable nothing wearing and tearing of last stamping die, increased the reliability of upper trimming die work greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Referring to Fig. 1 and Fig. 2,1 is last rail godet; 2 is circular orbit; 3 is upper plunger; 4 is the free wheel axle; 5 is nut; 6 is back-up ring; 7 is roller.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, the utility model comprises rail godet 1, the cylindrical of last rail godet 1 is provided with circular orbit 2, also comprise a upper plunger 3, also comprise a free wheel axle 4 that laterally runs through upper plunger, and two ends, free wheel axle 4 left and right sides adopt nut 5 fixing respectively, wherein the right end portion of free wheel axle 4 exposes to nut 5, and at the sheathed roller 7 of the exposed parts of free wheel axle and adopt back-up ring 6 fixing, the cylindrical of the roller 7 in the present embodiment just in time is slidingly connected with the circular orbit 2 of last rail godet 1, and roller 7 is orthogonal with the contact-making surface of circular orbit 2.
Tablet press machine by circular orbit 2 motions of roller 7 at last rail godet 1, contacts by idler wheel surface and orbital plane are smooth in operation, and running is easily stable, thereby has reduced the track friction resistance.Effectively guarantee the advantage of the stable nothing wearing and tearing of last stamping die, increased the reliability of upper trimming die work greatly.
