Circular pill coating machine for pharmacy

Abstract

The invention relates to the technical field of pharmaceutical equipment, and discloses a circular pill coating machine for pharmacy. The machine comprises a bottom plate, a supporting frame is fixedly connected to the upper portion of the bottom plate, a mounting frame is fixedly connected to the upper end of the supporting frame, and a rotating motor is fixedly mounted on one side of the mounting frame. An arc-shaped sliding groove and a sliding rod are arranged, after pill feeding is completed, the rotating motor rotates to control an outer barrel to be inclined, at the moment, a servo motor works to drive an inner barrel to rotate, the inner barrel driving pills to rotate, meanwhile, the inner barrel drives the sliding rod to rotate, the outer barrel moves back and forth, and meanwhile, the outer barrel drives the pills to rotate forwards and backwards so as to ensure that the pills can rotate and rotate forwards and backwards during coating. The problems that the pills are damagedand the percent of pass of the pills is seriously influenced due to collision between the pills and the inner wall of a roller and between the pills and a scraper are solved, meanwhile, each surfaceof the pills can uniformly receive a coating liquid during the coating, and the coating effect is improved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical equipment, in particular to a pharmaceutical round pill coating machine. Background technique [0002] The coating machine is a kind of high-efficiency, energy-saving, safe and clean mechatronics equipment that can coat tablets, pills, candies, etc. with organic film coating, water-soluble film coating, slow-release and controlled-release coating. The working principle is to pour a certain amount of tablets into the drum, start the motor to turn the drum over, and stir the tablets through the scraper inside the drum, and at the same time, the coating auxiliary materials are sprayed on the surface of the drug with a high-pressure film sprayer, so that the drug is coated on the surface. The drum moves in a continuous and complex trajectory, so that the coating solution is evenly coated on the tablet core of the drug, and at the same time, hot air is supplied under negative pressure, so that t...

AI Technical Summary

Problems solved by technology

[0003] But the existing pill coating machine also has the following problems in the actual use process: first, the existing coating machine makes the pills do continuous and complicated movements inside the drum through the rotation of the drum and the stirring of the scraper to achieve uniform coating. However, when the pills rotate inside the drum, they will inevitably collide with the inner wall of the drum and the scraper, which will easily cause damage to the pills, seriously affect the qualified rate of the pills, and cause waste of the pills; When coating in the drum, due to the influence of gravity, the pills will gather into a pile. Although the rotation of the drum and the scraper can disperse them, the pills will always gather together every time, resulting in a thick coating of the outer pills for a long time. Large, the coating thickness of the pills on the inner side for a long time is small, it is difficult to ensure uniform coating
