Embodiment Construction

[0009] As shown in the accompanying drawings, the coating drum of this coating machine includes a drum 1 and a stirring paddle 2. The paddle paddle 2 is welded on the inner wall of the drum 1. 6 is a welding point in the figure. The bottom of the padding paddle is arc-shaped, at least when the drum rotates. The bottom 5 on one side of the direction is arc-shaped. In this embodiment, both sides of the bottom of the stirring blade are arc-shaped, so that the shape of the stirring blade is smoother and easier to clean. The joint surface 3 between the inner wall of the drum 4 and the stirring paddle 2 has no mesh, which is convenient for the paddle to be welded on the inner wall of the drum. The rest of the inner wall of the drum can have no mesh or have mesh, depending on the requirements of the coating drum, the present embodiment is the mesh surface.

Abstract

A coating drum of coater used in pharmaceutical industry is composed of drum body and stirring blades fixed to inner surface of drum body. It is characterized by that said blade and inner surface of drum body are connected in arc mode, that is, there is a transition arc to make the tablet move smoothly in drum without residence and damage.

Description

technical field [0001] The invention relates to a coating drum of a coating machine used in the pharmaceutical industry, especially the improvement of the drum stirring paddle. Background technique [0002] The film coating machine widely used in the pharmaceutical industry is to make the tablet core of the drug to be coated in a continuous and complicated trajectory in the coating drum closed by the coating host. After the coating medium is dosed, the booster pump passes through Spray gun or dropper, automatically spray on the core surface. At the same time, in the negative pressure state, the hot air supplied by the hot air cabinet and filtered and heated by 100,000 grades is introduced from the upper part of the drum, and the moving core layer is drawn from the bottom of the drum by the exhaust fan and discharged after dust removal. The clean hot air makes the coating medium sprayed on the surface of the tablet core dry quickly and evenly, so that a firm, dense, flat and...
