Description

A kind of tablet density homogenizer of tablet press machine

Technical field:

The utility model relates to a kind of tablet press machine, relates in particular to and regulates mould in tablet press machine to float the device of homogenizing tablet press machine tablet density.

Background technology:

At present, tablet article are more and more general, use tablet Wu field and constantly expand, and market increases year by year to the demand of tablet thing.And tablet thing is made powder or particle with tablet press machine by high pressure mold pressing.Existing compressing tablet function is pressed into graininess, dusty raw materials in the tablet of various shapes, can suppress large product, simultaneously can a mould multi-disc, can be used for large-scale production industry, and die change is easy for installation, simple to operate easy to learn.The middle mould of existing tablet press machine is as shown in Fig. 1～Fig. 2, comprise middle core rod 1 and intermediate die plate 2, middle core rod 1 is fixedly mounted on the center of intermediate die plate 2, during compressing tablet, at upper die head, between the tablet die cavity of middle core rod 1 and lower die head, form compression molding chamber, when packing into after press-powder material to compression molding chamber, upper die head moves down in the tablet die cavity that is pressed into middle core rod 1, just can suppress required tablet, but, when pressing down, treats this structure upper die head that press-powder material upper strata is always stressed, lower floor is until compressing tablet finishes just stressed, will cause like this product to tighten lower pine, product density is inhomogeneous, inventor is through constantly test, invented a kind of tablet density homogenizer of tablet press machine, can solve existing issue.

Utility model content:

The purpose of this utility model is to provide a kind of tablet density homogenizer of tablet press machine, and it can make as required middle mould have individual amount of floating when compressing tablet, allows and treats that press-powder material pressurized is even, solves the problem of existing product Density inhomogeneity.

The technical scheme that the utility model is taked is as follows:

A kind of tablet density homogenizer of tablet press machine, comprise middle core rod and intermediate die plate, middle core rod is fixedly mounted on the center of intermediate die plate, it is characterized in that: fixed head in the middle of also comprising, the contour core in location and stage clip float, surrounding at intermediate die plate has flight, upper installing hole and compression spring groove, flight is above upper installing hole, compression spring groove is below upper installing hole, in middle fixed head correspondence, on core rod, the position of tablet die cavity has corresponding cavity hole, at the corresponding intermediate die plate of middle fixed head, have compression spring Cao position and have lower pressure spring slot, below lower pressure spring slot, have lower installing hole, the position of lower installing hole is corresponding with the position of upper installing hole, the contour core retainer plate in location that floats is contained in the upper installing hole of intermediate die plate and the lower installing hole of middle fixed head, compression spring sleeve is contained in floats on the contour core in location, stage clip is arranged in compression spring groove and lower pressure spring slot, height under stage clip normal condition be greater than compression spring groove and lower pressure spring slot height and, floating, contour Xin top, location has screwed hole, lock screw is fixedly mounted in the screwed hole of the contour core in location that floats, the screw terminal height of lock screw is less than the height of the flight on intermediate die plate.

Further, the height of the aspect ratio compression spring groove under stage clip normal condition and lower pressure spring slot and large 5mm～10mm.

Due to fixed head in the middle of being provided with below intermediate die plate, between intermediate die plate and middle fixed head, increased the contour core in unsteady location, on the contour core in unsteady location between intermediate die plate and middle fixed head, be set with stage clip, at upper die head, the tablet die cavity of middle core rod, in the compression molding chamber forming between the die cavity of middle fixed head and lower die head, pack into after press-powder material, upper die head moves down in the tablet die cavity that is pressed into middle core rod, press-powder material upper strata is treated in compacting, then patrix contacts intermediate die plate, intermediate die plate compressing stage clip is downward, continue again to press down, press-powder Liao lower floor is treated in compacting, thereby powder integral to be pressed is compressed real, so just can suppress required tablet, make product density even, can not cause the phenomenon that tightens lower pine.
