Abstract

The utility model discloses an oil collecting ring applied to high-speed rotary-type tablet machines and belongs to the pharmaceutical industry. In the practical production, tiny dark pots or smudges appear on the surfaces of many varieties of pills. A main reason is that an oil collecting ring installed on an upper punching rod is unreasonable. A traditional oil collecting ring is in a shape of a ring-shaped small bowl. The diameter D 2 of the bottom of the ring is equal to the diameter D 3 of the opening of the ring. Under the natural state, the diameter D 3 of the opening of the oil collecting ring is larger than the diameter D 2 of the bottom of the oil collecting ring. Under the assembling state, because the diameter D 1 of an inner hole inside the ring needs trapping firmly the upper punching rod as well, so an opening shrinking condition exists as well as the diameter D 3 of the opening of the ring. Because the diameter D 3 of the opening of the oil collecting ring under the natural state is larger than the diameter D 2 of the bottom of the oil collecting ring under the assembling state, the oil collecting ring keeps a large opening as well and is capable of catching fallen oil powder mixtures. The appearance of the tiny dark pots or the smudges on the pills is reduced greatly (under the same working condition, the rate of the tiny dark pots or smudges appearing on the pills is reduced by more than 90%). The quality of medicines is improved.

Description

Oil collecting ring

Technical field

The utility model is applied to Highspeedrotarytabletpress, belongs to pharmaceutical field.

Background technique

Highspeedrotarytabletpress is to meet necessarily required dryness granular or powder material, by moving up and down and the mould of circular movement, is pressed into the equipment of tablet under the effect of pinch roller.Have output large, simple to operate, the characteristics of being convenient to clear up, thus be widely used in pharmaceutical industry.In actual production, the tablet of a lot of kinds surface (especially white or light tablet) all tiny stain or stain can occur, and affects the appearance quality of tablet.A very large reason that pore or stain occur just is mounted in that oil collecting ring on the upper plunger is unreasonable to be caused.The tradition oil collecting ring is (nature) as shown in Figure 1, and such as the moulding of the little bowl of same annular, ring end diameter D2 equals collar extension diameter D3, and ring diameter of bore D1 tightly is enclosed within on the upper plunger.Its effect is: in a single day the mixture of lubricant oil and medicinal powder powder comes off on upper plunger, just falls into oil collecting ring, and oil collecting ring also hence obtains one's name.

After but traditional oil collecting ring is contained on the upper plunger, need tightly entangle upper plunger because of ring diameter of bore D1 place, therefore whole annular lower portion expands, and causes the top reducing, as shown in Figure 2 (assembling condition).D3 dwindles because of the collar extension diameter, causes the oil collecting ring reducing, and part oil-bound distemper mixture is not caught, and drops on the middle punch plate, sneaks into medicinal powder, finally causes the tablet surface tiny stain or stain to occur, and affects the appearance quality of tablet.

The model utility content

In view of the defective of traditional oil collecting ring, the utility model as shown in Figure 3.

Oil collecting ring is the hollow annular thing, it is characterized in that: the collar extension diameter of this oil collecting ring is greater than ring end diameter 1-2 millimeter.

The collar extension diameter is greater than ring end diameter 1-2 millimeter under the nature of this oil collecting ring.Under assembling condition, diameter of bore D1 need tightly entangle upper plunger equally because of ring, and there is the reducing phenomenon equally in collar extension diameter D3, because of collar extension diameter D3 under the nature greater than ring end diameter D2, so under the assembling condition of oil collecting ring of the present utility model near shown in Figure 1.

Even if under assembling condition, this oil collecting ring also keeps one than big open end, can catch the oil-bound distemper mixture that falls, and greatly reduces the appearance of stain in the tablet or stain (under the identical operating mode, the probability that occurs stain or stain in the tablet reduces more than 90%), improved the quality of medicine.

Embodiment

The collar extension diameter is greater than ring end diameter 1-2 millimeter, as shown in Figure 3 under the nature of this oil collecting ring.

Take the applicable oil collecting ring of D mould as example, D3 equals 37 millimeters, and D2 equals 36 millimeters.

Under assembling condition, diameter of bore D1 need tightly entangle upper plunger equally because of ring, and there is the reducing phenomenon equally in collar extension diameter D3, because of collar extension diameter D3 under the nature greater than ring end diameter D2, so under the assembling condition of oil collecting ring of the present utility model near shown in Figure 1.

The utility model has the advantages that the effect that more effectively realizes oil collecting ring, in actual production, greatly reduce the stain or the stain that occur in the tablet, improve the appearance quality of medicine.

Claims

1. oil collecting ring is the hollow annular thing, it is characterized in that: the collar extension diameter of this oil collecting ring is greater than ring end diameter 1-2 millimeter.
