Description

Technical Field

[0001] The invention relates to the technical field of coating machines, and in particular to a drum pan changing positioning structure for coating machines. Background Art

[0002] The coating machine is an efficient, energy-saving, safe and clean mechatronic equipment that can apply organic film coating, water-soluble film coating, slow-release and controlled-release coating to tablets, pills, candies, etc. The coating machine is suitable for the pharmaceutical, chemical, food and other industries. Its working principle is: the pot body rotates clockwise to make the sugar-coated tablets roll, slide, rub and grind in the pot, and the sugar-coated powder is poured into the pot by hand to make the sugar-coated powder evenly distributed on all the plain tablets. The electric heating blower that comes with it has an air outlet pipe that extends into the ball for heating. At the same time, the blower passes hot air into the inner layer of the pot to remove the surface moisture of the tablets, thereby obtaining rigid sugar-coated tablets.

[0003] The coating machine needs to replace the roller regularly and ensure the docking accuracy. The existing positioning device has the following defects when used:

[0004] 1. Generally, the drum needs to be bolted to the main drum mounting shaft of the coating machine. However, due to the large size, heavy weight and smooth surface of the drum, it is very inconvenient to move. In particular, during installation, the center of the drum needs to be concentrically aligned with the center of the main drum mounting shaft to facilitate the replacement of the drum.

[0005] 2. The initial positioning operation is difficult to achieve, and it can only be moved to the approximate position and then adjusted, which takes a long time to adjust. Therefore, we propose a drum pan changing positioning structure for the coating machine to solve the above-mentioned problems. Summary of the invention
