[0002] Perforated coating machines have been widely used in the pharmaceutical and food industries. In these industries, coating drug or food particles is a crucial step. This treatment method can not only significantly improve the appearance of drug or food particles, making them more attractive, but also effectively improve their stability, moisture resistance and taste. By coating, a protective film can be provided for drug or food particles, which helps prevent adverse effects on drugs or foods caused by external environmental factors such as humidity and temperature changes. In addition, coating technology can also be used to control the release rate of drugs, so as to achieve the effect of sustained release or targeted release, which is of great significance for improving drug efficacy and the convenience of patient medication. In the food industry, coating technology is equally important. It can keep food particles fresh, extend the shelf life, and at the same time increase the flavor and taste of food, enhancing the consumer's eating experience.

In the middle of the bottoms of the two push-pull cross bars 611, it is fixedly connected to the top of the push plate 57;

[0036] When the material needs to be coated, first, valve 28 is opened, and the material falls from the storage bin 27 into the feeding pipe 26 and then through the feeding pipe 26 onto the inner wall of the rotating barrel 23. At this time, the nozzle body 512 is inside the inner wall of the outer protective pipe 51 of the nozzle, and multiple fan-shaped closing blocks 517 are closed to seal the bottom of the outer protective pipe 51 of the nozzle, preventing the dust generated during the falling process of the material from drifting and blocking the bottom end of the nozzle body 512. When the material has been fed to the inner wall of the rotating barrel 23, the hydraulic push rod 43 is started at this time. The start of the hydraulic push rod 43 drives the inverted U-shaped push-pull block 44 to slide to the left or right on the inner wall of the guide groove 42. The sliding of the inverted U-shaped push-pull block 44 drives the rotation of the Z-shaped rotating rod 45, causing the slurry nozzle 5 to rotate around the nozzle connecting block 46, thereby adjusting the inclination angle of the slurry nozzle 5. Then, the second hydraulic push rod 56 is started. The start of the second hydraulic push rod 56 drives the pulling push-pull cross bar 611 to move downward. The downward movement of the push-pull cross bar 611 drives the push-pull round shaft 511 and the slurry feeding pipe 510 inside its inner wall to move downward. While the slurry feeding pipe 510 moves downward, it drives the rotating rod 514 to rotate on the outer wall of the rotating rod hinge shaft 513. The rotation of the rotating rod 514 drives the expansion and contraction rod 515 to slide on the inner wall of the chute 53. The sliding of the expansion and contraction rod 515 drives the expansion and contraction vertical plates 516 to move away from each other. The movement of the expansion and contraction vertical plates 516 drives the fan-shaped closing blocks 517 to move away from each other, thereby opening the bottom of the outer protective pipe 51 of the slurry nozzle. At this time, the nozzle body 512 is pushed out of the bottom of the outer wall of the outer protective pipe 51 of the nozzle by the slurry feeding pipe 510 and is in a working state. At the same time, when the push-pull cross bar 611 moves downward, it drives the two push-pull vertical rods 610 to move downward. The downward movement of the two push-pull vertical rods 610 pushes the two double hinge blocks 69 to rotate around the axis rod 64, causing the two L-shaped connecting rods 67 to drive the dust-proof plate 68 to rotate to an inclined state. At this time, the dust-proof plate 68 blocks the bottom of the nozzle body 512 extending out of the bottom of the outer protective pipe 51 of the nozzle at an inclined angle of 45 degrees, and the inner side of the dust-proof plate 68 is designed as a mesh. Therefore, when the rotating barrel 23 rotates, it can effectively prevent the dust splashed by the rotation of the material from adhering to the outer wall of the nozzle body 512, ensuring the normal operation of the nozzle body 512. At the same time, the extension degree of the nozzle body 512 and the inclination angle of the dust-proof plate 68 can be adjusted according to actual needs, enabling the slurry to be evenly sprayed on the material on the inner wall of the rotating barrel 23, improving the coating effect. At this time, the blower 12 is started. The blower 12 generates air flow when it works. The air flow enters the air box 14 through the air duct 13 and then is evenly blown out from multiple air outlets 16 through the air box pipe 15, forming an air flow surrounding the rotating barrel 23. This air flow not only helps the slurry to dry evenly and quickly but also prevents the dust generated during the coating process from drifting everywhere, further ensuring the cleanliness of the working environment.

[0037] Working principle of the present invention: When coating the material is required, first, the valve 28 is opened, and the material falls from the storage bin 27 into the feeding pipe 26 and then through the feeding pipe 26 onto the inner wall of the rotating barrel 23. At this time, the nozzle body 512 is inside the inner wall of the outer protective pipe 51 of the nozzle, and multiple sector-shaped closing blocks 517 are closed to seal the bottom of the outer protective pipe 51 of the nozzle, preventing the dust generated during the falling process of the material from spreading and blocking the bottom end of the nozzle body 512. When the material is completely fed onto the inner wall of the rotating barrel 23, the hydraulic push rod 43 is started at this time. The start of the hydraulic push rod 43 drives the inverted U-shaped push-pull block 44 to slide left or right on the inner wall of the guiding groove 42. The sliding of the inverted U-shaped push-pull block 44 drives the rotation of the Z-shaped rotating rod 45, so that the slurry nozzle 5 rotates around the nozzle connecting block 46 as the center, thereby adjusting the inclination angle of the slurry nozzle 5. Then, the second hydraulic push rod 56 is started. The start of the second hydraulic push rod 56 drives the pulling push rod 611 to move downward. The downward movement of the push rod 611 drives the push-pull round shaft 511 and the slurry feeding pipe 510 inside its inner wall to move downward. While the slurry feeding pipe 510 moves downward, it drives the rotating rod 514 to rotate on the outer wall of the rotating rod hinge shaft 513. The rotation of the rotating rod 514 drives the expansion and contraction rod 515 to slide on the inner wall of the sliding groove 53. The sliding of the expansion and contraction rod 515 drives the expansion and contraction vertical plates 516 to move away from each other. The movement of the expansion and contraction vertical plates 516 drives the sector-shaped closing blocks 517 to move away from each other, thereby opening the bottom of the outer protective pipe 51 of the slurry nozzle. At this time, the nozzle body 512 is pushed out of the bottom of the outer wall of the outer protective pipe 51 of the nozzle by the slurry feeding pipe 510 and is in a working state. At the same time, when the push rod 611 moves downward, it drives the two push-pull vertical rods 610 to move downward. The downward movement of the two push-pull vertical rods 610 pushes the two double hinge blocks 69 to rotate around the axis rod 64, so that the two L-shaped connecting rods 67 drive the dust-proof plate 68 to rotate into an inclined state. At this time, the dust-proof plate 68 blocks the bottom of the nozzle body 512 extending from the bottom of the outer protective pipe 51 of the nozzle at an inclined angle of 45 degrees. At this time, the blower 12 is started. The blower 12 generates air flow during operation. The air flow enters the air box 14 through the air pipe 13 and then is evenly blown out from multiple air outlets 16 through the air box pipe 15, forming an air flow surrounding the rotating barrel 23.
