Abstract

The invention discloses a coating machine internal pressure control mechanism, and relates to the technical field of pharmaceutical machinery, the coating machine internal pressure control mechanism comprises a shell, the outer wall of the shell is sleeved with an air pressure control mechanism, one side of the shell is provided with a driving motor, the inner wall of the housing is provided with a stirring cylinder, and the outer wall of the stirring cylinder is connected with a plurality of groups of driving teeth in the shell; a circulating mechanism is arranged on one side of the shell and extends to the inner side of the stirring barrel. By arranging the air pressure control mechanism and the circulating mechanism, when air pressure control is carried out, the internal volume of the coating machine can be effectively changed through the change of the flexibility of flexible glue, so that the internal pressure of the coating machine is adjusted, air does not need to be exhausted, air can be supplemented into the coating machine through the air supplementing pipe when the air pressure is too small, the problem that the coating machine is inconvenient to open due to too small air pressure is solved, and the problem that raw materials are easy to discharge during pressure regulation is effectively solved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical machinery, in particular to an internal pressure control mechanism of a coating machine. Background technique [0002] A coating machine is a device that wraps a polymer around the tablet core to form a film. That is, spray the solution of the coating machine onto the surface of the rolling tablet core by spraying, and pass hot air to evaporate the solvent on the rolling tablet core, so that a continuous polymer film is formed on the surface. , To ensure that the pressure inside the coating machine is maintained within an appropriate range, a pressure regulating mechanism is needed. [0003] However, the existing pressure regulating mechanism usually uses a fan to control the pressure, and usually injects air into the coating machine or discharges air during pressure regulation, which will cause the concentration of droplets in the coating machine and The flow direction changes, which wil...
