Tablet press machine

Abstract

A tablet press (1), which includes a fixed box (2) that houses a compression device (3). The compression device is composed of a power-driven rotating body (4), which rotates around Rotating on an axis (5), the rotating body (4) includes a mold plate (6) and two other plates (7, 8) located on both sides of the mold plate. These two plates are each assembled opposite and each pair of Two sets of reciprocating punches (9, 10) aligned with each other. The mold plate (6) has a plurality of mold cavities (11), and the punches (9, 10) forming each pair of reciprocating punches are assembled in the mold cavities to form a space (12) with a variable size between them. ), used to hold a dose of powder to be compressed. Two sets of cams (13) and cams (14) are connected with the compression device (3), and when the rotating body (4) rotates, the two sets of cams transmit driving force to the punches (9, 10), and the driving force causes The punches move cyclically towards and away from each other to compress the powder contained in the dies (11) of the die plate (6). The box (2) includes sealed partitioning devices (15; 18, 19, 21, 22), which are used to form separated spaces (16, 17, 20), and these separated spaces are used to accommodate compression devices. (3) and two sets of cams (13; 14) to prevent powder products from contaminating the cams.

Description

technical field [0001] The present invention relates to a tablet press machine for the production of tablets, in particular tablets made of suitably formulated and dosed solid substances in powder or granule form, but this does not limit the scope of the invention . [0002] In particular, the present invention relates to a known tablet press comprising a compression device consisting of a rotating body rotatably housed in a case or fixed structure. Background technique [0003] The rotating body includes a matrix disc and two other discs located on both sides of the matrix disc, each of which is equipped with a set of relative reciprocating punches, and each set of reciprocating punches is connected to the other disc. The corresponding set of punches are aligned, thus forming multiple pairs of punches. [0004] The die plate also has a plurality of through matrices, in which each pair of reciprocating punches is assembled so as to define a variable-sized space between eac...

AI Technical Summary

Problems solved by technology

The fact that the parts for the mechanical transmission of the driving force still remain in the tablet press space is a disadvantage, since it still takes a lot of time to clean these parts, remove powder product residues and lubricants, which are essential for these It is necessary for the components to work correctly, but they are also contaminated by the powder product being processed, and there is also a considerable amount of time required to add clean lubricants before reassembling and starting up the tablet press for another processing cycle
