Description

Technical Field

[0001] The invention relates to the technical field of chemical medicine, in particular to a coating machine for surface treatment of western medicine tablets. Background Art

[0002] Some Western medicine tablets need to undergo a coating process after extrusion, granulation and other processes. The coating process is to wrap sugar or other film-forming materials on the surface of the solid drug preparation in a coating machine according to a specific process. The coating material is then dried by hot air to form a protective layer that tightly adheres to the surface of the drug. Existing coating machines for Western medicine tablet surface treatment need to push the material box into the drying chamber of the machine after coating. Some coating liquid may remain in the material box, causing the material box to drip into the machine during transportation, resulting in waste. At the same time, some tablets are easily affected by the coating liquid and stick together. It is necessary to propose a solution to the above technical problems.

[0003] As shown in the patent document with publication number CN114345784B, the device starts the second motor, and its output end drives the take-up reel to rotate to place the material box into the liquid storage tank to start coating. After the coating is completed, the output end of the second motor drives the take-up reel to rotate in the opposite direction to lift the material box to a position between the two diverters. At the same time, the setting of the guide block prevents the material box from shaking randomly in the machine body and causing damage. The drying area is located above the coating area so that the coating liquid dripping from the material box can directly drip back into the liquid storage tank to avoid waste. At the same time, the air outlet end of the diverter is tilted downward to prevent the coating liquid from dripping into the diverter and causing blockage. After the first motor is started, the output end drives the material box to rotate and multiple first levers to rotate through the linkage rod, while the second lever is fixed to one side of the bracket and does not follow the rotation of the material box, so that the first lever and the second lever move relative to each other, which is convenient for separating multiple connected tablets, effectively reducing the waste of coating liquid and avoiding the occurrence of multiple tablets being connected together;

[0004] However, after the above-mentioned device is used, a small amount of coating liquid will remain on the inner walls of the spray head and the spray tube. If it is not cleaned up in time, it will easily cause blockage. If it is directly rinsed with clean water, the splashing sewage will easily affect the dried western medicine tablets. At the same time, since the spray head and the section of the spray tube close to the spray head are in the rolling shell, when the spray head sprays out the atomized coating liquid, the atomized coating liquid will adhere to the outer wall of the spray head and the section of the spray tube close to the spray head. If it is not cleaned in time, bacteria will breed, which will easily affect the product quality of the western medicine tablets. Summary of the Invention

[0005] The technical problems solved by this solution are:

[0006] (1) How to solve the problem that the atomized coating liquid adheres to the spray head and the outer wall of the spray pipe near the spray head, which may affect the quality of Western medicine tablets if not cleaned in time;

The extended end of the cylinder is contracted from the third set length to the shortest. At this time, the spray head is located on the side away from the extension hole in the cleaning box. At the same time, the bottom end of the baffle plate moves downward to drive the flip plate to flip, so that the bottom of the guide groove corresponds to the bottom position of the spray head.
