Problems solved by technology

In the prior art, a seal ring 3' is installed between the vertical shaft 1 and the work surface 2, see figure 1 , but the structure of the sealing ring 3' in the prior art, its inner wall is completely in contact with the vertical shaft, not only the frictional resistance is large, but also the sealing ring is easy to wear, and the powder will enter the bearing of the vertical shaft

Embodiment Construction

[0010] See figure 2 , the sealing ring 3 of the present invention, its inner diameter gradually decreases from bottom to top. Moreover, the upper surface of the sealing ring is in a convex arc shape.

[0011] See image 3 , the sealing ring 3 of the present invention is installed on the bearing, and only the upper edge of the inner ring is in contact with the vertical shaft 2. During the normal operation of the automatic capsule filling machine, the vertical shaft 1 reciprocates up and down. Since the inner ring of the sealing ring 3 has a small contact area with the vertical shaft 1, the frictional resistance between the sealing ring 3 and the vertical shaft 2 is reduced, and the vertical shaft moves up and down. It is more flexible; and the frictional resistance is reduced, which also makes the sealing ring less prone to wear. Since the upper surface of the sealing ring is in a convex arc shape, the medicine powder falling on the sealing ring will flow on the workbench 2...

Abstract

The invention discloses a sealing ring of a fully automatic capsule filler. The internal diameter of the sealing ring is gradually reduced from bottom to top, and the upper surface of the sealing ring is an arc which protrudes outwards. The frictional resistance between the sealing ring and a vertical shaft is little and the sealing ring is not easy to wear; after falling on the sealing ring, medicinal powder can slide along the surface of the sealing ring and fall on a table-board so as not to enter in a bearing.

Description

technical field [0001] The invention relates to a sealing ring of a full-automatic capsule filling machine, in particular to a sealing ring structure used on a transmission bearing of the full-automatic capsule filling machine. Background technique [0002] The drug capsule is divided into a capsule body and a capsule cap, the capsule body is partially filled with drug powder, and the capsule cap is installed at the mouth of the capsule body to form a closed capsule. The production of capsules by a fully automatic capsule filling machine generally goes through the process of separating the capsule body and cap - metering powder filling - capsule waste removal - capsule locking - finished product release - powder cleaning and other processes. In the process of metering and filling the above-mentioned capsules, the powder will inevitably spill on the working table; while in the process of capsule locking, the automatic capsule filling machine transmits the power to the vertica...
