A coating device for the enteric layer of bisacodyl enteric tablets

Abstract

This utility model relates to the technical field of coating devices, specifically a coating device for the enteric coating layer of bisacodyl enteric-coated tablets. It includes a cabinet with a roller inside. A rotating ring is connected to the left side wall of the cabinet, and the left end of the rotating ring is rotatably connected to the inner left side wall of the cabinet via a bearing. In operation, bisacodyl tablets are placed into the roller, the door is closed, and a motor drives the drive wheel, transmission belt, driven wheel, rotating ring, and roller to rotate. Support rollers provide support and improve the stability of the roller's rotation. A peristaltic pump draws and delivers the coating solution to the nozzle of a spray gun. The spray gun is connected to a compressed air pipeline, and the compressed air is used to evenly spray the coating solution onto the surface of the bisacodyl tablets for coating. The rotation of the roller causes the tablets to continuously rotate, ensuring the uniformity of the coating solution spray, thereby effectively coating the surface of the bisacodyl tablets with an enteric coating layer.
