Description

Technical Field

[0001] The utility model relates to the technical field of capsule filling machines, in particular to a filling mechanism for capsule filling machines. Background Art

[0002] Capsule filling machine is a commonly used medical mechanical equipment, which is used to load drug powder or liquid into capsules according to a certain proportion. When the machine is running, the capsules in the capsule barrel at the first station will vertically enter the capsule feeding plate one by one, first pushed to the outer end of the correction block by the horizontal fork, and then into the mold hole by the vertical fork and vacuum suction, and the cap and body will be separated. At the second station, the lower module descends and moves outward. The third station is equipped with a micro-pill device for filling sustained-release micro-pills. The fourth station is for powder filling. The powder in the medicine chamber is pushed into the capsule body after five filling and compression.

[0003] When the capsule filling machine is working, the medicine powder continuously flows out from the discharge pipe in the capsule filling machine. After long-term use, the medicine powder often adheres to the inner wall of the discharge pipe of the capsule filling machine, and the accumulation will affect the discharge. When a blockage occurs, the operator usually stops the capsule filling machine first, and uses tools to dredge the discharge pipe before the capsule filling machine can continue to work. When the capsule filling machine is stopped before the dredging work can be performed, the working efficiency of the capsule filling machine will be affected. Utility Model Content
