SU107963A1 - Tritour tablet machine - Google Patents

Description

The subject of the invention is a laminate for the production of trituration tablets using a loading hopper for tablet mass and a multi-bed matrix with punchonol, driven by an eccentric mechanism, kinematically associated with a drive motor.

The advantage of the proposed machine in comparison with the known ones is its high productivity, which is achieved by the fact that a tea-like bunker for tablet mass is made movable by means of a lever device, kinematically connected with a driving electric motor and telling the bunker a reciprocating motion along the lower surface of the matrix.

The bottom of the bunker is made in the form of a piston acting from a screw mechanism in synchronization with the movement of the bunker and ensuring that the hopper moves twice in one cycle of the holes of the matrix with a tablet mass.

FIG. 1 shows a longitudinal section of the machine; in fig. 2 is a section along AA in FIG. one; in fig. 3 is a view along arrow B in FIG. B in FIG. 4 - drive unit of the machine.

In the lower part of the bed / welded from pipes and channels, there is a drive unit of the machine, and on the upper frame there are mechanisms for forming tablets.

For loading the medicinal mass, there is a bunker 2 having a movable bottom made in the form of a piston 3 with a screw shank 4 and a round nut 5 placed with small gaps between the sides of the support sleeves 6: this forms a screw mechanism for lifting the piston. The bunker reciprocates, for this purpose it is equipped with rollers 7, which roll along four guides 8.

An electric motor 9 is installed to drive the machine, transmitting rotation through a belt drive to a worm gearbox, on whose shaft a cam / U and crank 12 are fixed on both sides. LJJaTyn 13 reports a swinging motion to the lever 14, which is then converted into reciprocating-forward movement . The cam 11 controls the movements of the core disk with a pusher and lever 16 (Fig. 3).

The pressing mechanism consists of a fixed matrix disk / 7 with a large number of sockets and a movable disk 18 with punches - according to the number of nests in the matrix. The matrix disk can be adjusted in height, for this purpose adjusting nuts 20 and spacer springs 21 are provided on the four studs J9 of its mounting.

The process of making the tablets is as follows. The hopper 2 with a tablet mass moves under the influence of the lever 14 along the direction of 8 under the matrix disk 17. A sealing plastic ring 22 is provided for a snug fit of the hopper to the disk.

When the bunker approaches its extreme position under the matrix, the bin begins to rise and press the tablet mass into the hole of the matrix. Towards the end of the movement, i.e., when the axes of the matrix disk and the hopper are combined, the bunker piston rises to a predetermined height. When the bunker moves backward, the rubbing mass operation is repeated, this results in the delivery of the required dose of substance for each batch of tablets. Therefore, in. the machine is provided, during one cycle of the movement of the bunker, twice filling the holes of the matrix with a solid mass.

The lift of the bunker by a given amount corresponding to the set dose occurs in

By turning the nut 5, which is driven by the paws 23 and 24, acting alternately, depending on the direction of movement of the hopper, on the protrusions 25 of the round nut of the screw mechanism.

After the hopper is retracted to its initial position, the disk with punches to the action. The springs 26 and, in accordance with the cam profiling, is lowered down, and the punches squeeze out the cylindrical columns of the mass from the holes of the matrix disk. During the subsequent movement of the bunker, the knife 27 cuts off the columns and drops them in the form of tablets into the receiving tray.

PREPARATION AND RESULTS

Claims (2)

1. A machine for the manufacture of trituration tablets, using a loading hopper for the tablet mass and a multi-seat matrix with a punch, driven by an eccentric mechanism, kinematically connected with a drive motor, c. By the fact that, in order to increase the productivity of the machine, the cup-shaped bunker for the tablet mass is made movable by means of a lever device, kinematically connected with the drive motor and telling the tank a returnable movement along the lower surface of the die. 2. L1 machine according to claim 1, characterized in that, in order to eliminate unproductive loss of the tablet mass, the bottom of the bunker is made in the form of a piston, actuated by a screw mechanism synchronously with the reciprocating movement of the bunker and providing two times the movement of the bunker filling the holes of the matrix tablet mass. ool txl IS Qi: iJ (ABOUT ...., 1 Q -ri  wfi jj1 ii j- , rl;: ii j I
