A pharmaceutical capsule grinding and polishing machine

Abstract

The invention relates to the technical field of pharmaceutical production equipment, in particular to a grinding and polishing machine for a medicine capsule. The grinding and polishing machine for the medicine capsule comprises a machine body, a feeding mechanism and a waste collecting mechanism, wherein the feeding mechanism is under the machine body, and the waste collecting mechanism is underthe machine body. A grinding and polishing device is arranged in the machine body. The grinding and polishing device comprises a rotating shaft, a coarse throwing bucket and a fine throwing bucket, wherein the coarse throwing bucket is fixedly connected with the rotating shaft, and the fine throwing bucket is arranged on the lower portion of the coarse throwing bucket. A spiral material returningblade is arranged in the coarse throwing bucket. A first bushing is arranged in the outer surface of the fine throwing bucket, and the first bushing is a spiral shape. The inner surface of the fine throwing bucket is provided with a second bushing, and the second bushing and the first bushing are in an opposite spiral shape. The upper portion of the machine body is provided with a first driving motor which is used to drive the rotating shaft to rotate. According to the graded polishing toward the capsule, the polishing effect of the capsule is improved. The rotating shaft is arranged into a hollow structure, the air flow inside the rotating shaft improves the air selection of the capsule only with a shell, and the effect of air selection and polishing is good.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical production equipment, and is aimed at the grinding and polishing of finished pharmaceutical products, in particular to a pharmaceutical capsule grinding and polishing machine. Background technique [0002] In the field of medical drugs, capsules have a certain protective effect on the drugs because they can wrap a certain amount of drugs, and the capsules can wrap the bitter taste or other odors of the drugs, so as to avoid the patient's rejection of the drugs when the drugs are taken directly. Circumstances have been widely used. However, in the process of capsule production and drug filling, it is inevitable that drug dust will adhere to the shell of the capsule, making the surface of the capsule not smooth enough. Therefore, after the production of the capsules is completed, the capsules need to be polished to remove the drug powder on the surface of the capsules, improve the surface fi...

Problems solved by technology

Although the invention improves the polishing effect through the vertical polishing structure, the invention sets the suction cup above the polishing mechanism, making it difficult to select empty capsules, and the polished capsules are discharged from the bottom of the polishing mechanism, while the suction cup At the top, some powder will fall into the discharge port under gravity, causing the polished capsule to stick to the powder again, making the polishing effect not good
