Abstract

The invention relates to mechanical engineering, namely to rotary machines. The goal - the expansion of technological capabilities. The hollow body 8 of the collector for removing excess press material is arrow-shaped, pointing its apex in the direction opposite to the direction of rotation of the rotor, and provided with spring-loaded arms installed in its grooves. 3 il.

Description

The invention relates to mechanical engineering. namely, rotary machines.

The purpose of the invention is the expansion of technological capabilities by reducing the loss of powder and eliminating ingress of residues of the press material into the matrix.

FIG. 1 shows the machine, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 section BB nafig. one.

The rotary tablet machine contains a rotor 1 with dies 2 and a drive for its rotation (not shown), the top 3 and bottom 4 punches, a feeder 5 with a metering wall 6 and a table 7. A dimple set is installed above the dies 2 to remove excess press material with a swept body. 8, directed by its apex in the direction opposite to the direction of rotation of the rotor 1i

The housing 8 is tightly pressed to the feeder 5 and is connected to a vacuum system. In the slots of the housing 8 installed spring-loaded knives 9.

Rotary machine works as follows.

The rotor 1 is rotated clockwise with the dies 2. The dies 2, the passage under the feeder 5. are filled with press material up to the level of the lower punch 4 and are metered by the wall 6 of the feeder 5. In this case, the excess of the press material falls on the surface of the rotor 1, is removed from the zone of the feeder 5, cut off from the rotor 1 by spring-loaded knives 9, on either side of the die 2, are guided into the hollow body 8 of the collection. the matrix 2 which is thus withdrawn is shielded from the excess of the press material until it is closed by the upper punch 3. The press material, thrown off by centrifugal force from rotor I to table 7, is also assembled by spring-loaded knives 9 and sent to the hollow body 8, from which it is sucked off by a vacuum by the system.

A rotor on a tablet machine comprising a rotor with dies and a drive for its rotation, coaxially arranged upper and lower punches, a feeder, and also a collector for removing excess press material with a hollow body connected to

vacuum system, characterized in that. that, in order to expand technological capabilities by reducing powder losses and eliminating the remnants of the press material in the matrix, it is equipped with spring-loaded, and the hollow body of the collection is swept with vertical grooves in the body, mounted above the matrices opposite to the direction of rotation rotor, tightly pressed to the feeder, while the spring-loaded knife-mounted in the vertical slots of the hollow body.
