Abstract
Description
Technical Field
[0001] This utility model belongs to the field of capsule production technology, and in particular relates to a capsule polishing device. Background Technology
[0002] In the pharmaceutical industry, a small amount of powder adheres to the surface of capsules after they have been filled with medication. To improve the appearance of drug capsules and increase the credibility of the drugs, the surface of the capsules must be polished.
[0003] Currently, brush roller polishing equipment is commonly used to polish capsules. To improve the surface cleanliness of the capsules after polishing, this equipment is equipped with a two-stage polishing mechanism, such as... Figure 1 As shown, the system includes a dust removal mechanism 100 for preliminary removal of powder from the capsule surface and a polishing mechanism 200 for polishing the capsules after preliminary dust removal. The dust removal mechanism 100 includes a sealed box 101 and a brush 102 installed inside the sealed box 101. The brush 102 rotates to initially remove powder from the capsule surface inside the sealed box 101, achieving preliminary dust removal. After preliminary dust removal, the capsules, along with the swept-off powder, are output through a guide plate 103. During the output process, the powder falls through through holes in the guide plate 103 into a collection box. The dust removal mechanism 200 includes a sealed cylinder 201 with a rotating shaft and a spiral brush 202. The spiral brush 202 is used to remove remaining powder from the capsule surface. The beginning of the sealed cylinder 201 is connected to the sealed box to receive capsules from the sealed box 101. The end of the sealed cylinder 201 has a discharge port 203 for outputting capsules, and the bottom of the sealed cylinder 201 has several dust collection holes 204 for powder output. The dust removal and polishing mechanisms in this capsule polishing equipment work together to form a two-stage polishing operation mode, which improves the removal of drug powder from the capsule surface and enhances the cleanliness of the capsule surface.
[0004] However, this brush roller polishing equipment with a secondary polishing mechanism has the following drawbacks: First, after the capsules complete the initial dust removal process in the sealed box 101, when they are output to the polishing mechanism via the guide plate 103, the capsules and the swept-off powder mix together, causing some powder to re-adhere to the capsule surface, reducing the initial dust removal effect. Second, when the capsules are being polished in the polishing mechanism, the spiral groove of the spiral brush 202 cannot be aligned with the dust collection hole 204 in real time during rotation. This means that the powder falling from the capsules in the spiral groove cannot be discharged from the dust collection hole 204 in a timely manner, reducing the polishing effect and efficiency of the capsules.
