Since the automated filling equipment in the existing milk powder production line may cause the inside of the milk powder cans to be contaminated by external bacteria during the transportation of the milk powder cans, it is impossible to fully guarantee the sterile environment inside the tank, thereby reducing the quality of the canned milk powder products. Summary of the Invention

When the turntable 5 rotates and transports the milk powder can, the servo motor 222 can be started to drive the winding rod 221 to rotate clockwise on the groove frame 21, winding up the pull rope 223, and driving the sliding frame 23 to move upward in the inner wall of the groove frame 21, so that the spring 224 on one side is stretched, thereby lifting the sterilization mechanism 24 and the collection and cleaning mechanism 25 to facilitate the transportation of the milk powder can. When it is transported to a certain position, the servo motor 222 can be started to reverse, thereby driving the winding rod 221 to perform the unwinding operation, and then under the resetting action of the spring 224, the sliding frame 23 can be driven to move downward, and the sterilization mechanism 24 and the collection and cleaning mechanism 25 can be placed in the milk powder can for disinfection and sterilization operations and collection and cleaning operations, so as to achieve intermittent rotation and transportation of the turntable 5, intermittent and stepwise disinfection and sterilization cleaning of the interior of the milk powder can, so that the interior of the can is in a sterile environment before filling, thereby improving the quality of the canned milk powder product. The lifting mechanism 22 also includes a telescopic rod 225. The outer surface of the telescopic rod 225 extends through the interior of the spring 224, and its ends are fixedly mounted on one side of the inner wall of the groove frame 21 and one side of the sliding frame 23. The provision of the telescopic rod 225 supports and reinforces the inner wall of the spring 224, making it less susceptible to damage during use and extending its service life.

After the sliding frame 23 slides downward to a certain position, it will drive the air duct 244 and several arc-shaped tubes 245 to insert into the interior of the milk powder can. At this time, the air pump 242 can be started to suck the outside air into the interior of the wind guide cover 241, and the heating tube 243 is started to heat. When the wind passes through the surface of the heating tube 243, the wind will undergo heat exchange to form hot air, which then flows into the interior of the air duct 244 and is discharged by the several arc-shaped tubes 245. Since the arc-shaped tube 245 is arc-shaped, it will drive the air duct 244 to rotate on one side of the wind guide cover 241 when discharging the hot air, thereby heating the interior of the milk powder can. The rotary high-temperature sterilization process is carried out, which not only performs high-temperature sterilization, but also blows away impurities attached to the inside of the milk powder can, making it easier to collect and clean it later. After the hot air high-temperature sterilization, the lifting mechanism 22 drives the air guide cover 241 and the air duct 244 to rise to a certain position, and then the milk powder can is transported and rotated, and then it is located directly below the ultraviolet lamp 247.

After the sliding rack 23 slides downward to a certain position, the conveying pipe 251 and several dust hoods 252 will be placed inside the milk powder can. At this time, the fan 253 can be started to use the dust hood 252, the conveying pipe 251 and the guide pipe 255 to draw out the air inside the milk powder can, and then enter the cloth bag 254. The gas will pass through the cloth bag 254 and be discharged. The impurities blown in during the previous hot air high-temperature sterilization process and the scattered milk powder dust will be retained in the cloth bag 254 and collected, thereby improving the cleanliness of the inside of the milk powder can and facilitating the improvement of the quality of the canned milk powder products in the later stage.

[0032] Figure 1-6 A detachable device 3 is provided between one side of the groove frame 21 and the outer surface of the filling machine 1. The detachable device 3 includes a rectangular groove block 31, one side of which is fixedly mounted on the outer surface of the filling machine 1 and has a threaded hole 32 formed on one side of the inner wall of the rectangular groove block 31; a screw hole block 33, one side of which is fixedly mounted on one side of the groove frame 21 and one end of which is inserted into the inner wall of the rectangular groove block 31; and a bolt 34, one end of which is screwed into the inner walls of the screw hole block 33 and the threaded hole 32. By providing the detachable device 3, when the disinfection device 2 needs to be replaced or maintained, the bolt 34 can be manually screwed out of the threaded hole 32 and the inner wall of the screw hole block 33. Then, by pulling the groove frame 21 upward, the screw hole block 33 on one side can be pulled out from the inner wall of the rectangular groove block 31, thereby removing it from the filling machine 1 for easy maintenance and replacement.

[0033] Working principle: When using the filling machine 1 to fill milk powder into milk powder cans, the milk powder cans are usually placed on one of the conveyors 4 for transportation. When they are transported to a certain position, they will be stuck in the inner wall of the turntable 5. At this time, the driving mechanism inside the filling machine 1 can be started to drive the turntable 5 to rotate at a constant speed. Here, the driving mechanism can be a driving motor that directly drives the turntable 5 to rotate through a coupling to transport multiple milk powder cans at equal distances. At this time, the servo motor 222 can be started to drive the winding rod 221 to rotate clockwise on the groove frame 21, and the pull rope 223 can be wound up, driving the sliding frame 23 to move upward in the inner wall of the groove frame 21, so that the spring 224 on one side is stretched, thereby allowing the air guide cover 241 to be opened. The air duct 244, several ultraviolet lamps 247 and the dust cover 252 are lifted to facilitate the transportation of the milk powder can. When it is transported to a certain position, the servo motor 222 can be started to reverse, thereby driving the reeling rod 221 to perform the unwinding operation, and then under the reset action of the spring 224, the sliding frame 23 can be driven to move downward, and the air duct 244 and several arc tubes 245 are inserted into the interior of the milk powder can. At this time, the air pump 242 can be started to suck external air into the interior of the wind guide cover 241, and the heating tube 243 is started for heating. When the wind passes through the surface of the heating tube 243, it will cause the wind to undergo heat exchange to form hot wind, which then flows into the interior of the air duct 244 and is discharged by several arc tubes 245. The tube 245 is in an arc shape. When the hot air is discharged, it will drive the air duct 244 to rotate on one side of the air guide cover 241, and perform a rotary high-temperature disinfection on the inside of the milk powder can. This not only can perform high-temperature disinfection, but also can blow away the impurities attached to the inside of the milk powder can, which is convenient for later collection and cleaning. At the same time, when it descends through the lifting mechanism 22, the ultraviolet lamp 247 is started to perform ultraviolet irradiation sterilization on the inside of the milk powder can, and it will also drive the conveying pipe 251 and several dust hoods 252 to be placed inside the milk powder can. At this time, the fan 253 can be started to use the dust hood 252, the conveying pipe 251 and the guide pipe 255 to draw the air inside the milk powder can outwards, and then enter the cloth bag 25 4, the gas will pass through the cloth bag 254 and be discharged, while the impurities blown in during the hot air high-temperature sterilization process and the scattered milk powder dust will be retained in the cloth bag 254 and collected, so as to achieve the intermittent rotation and transportation of the turntable 5, and the interior of the milk powder can is intermittently and gradually disinfected and sterilized, so that the interior of the can is in a sterile environment before filling, thereby improving the quality of the canned milk powder product. When the turntable 5 transports the milk powder can to the bottom of the filling barrel 6, the filling machine 1 can be started to drive the electromagnetic valve inside the filling barrel 6 to open, and the milk powder can be filled into the milk powder can to complete the filling. Then, the turntable 5 continues to rotate to transport the milk powder can filled with milk powder to the second conveyor 4 for transmission.

[0034] When the disinfection device 2 needs to be replaced and maintained, the bolt 34 can be manually screwed out from the threaded hole 32 and the inner wall of the screw hole block 33, and then the groove frame 21 can be pulled upward to pull the screw hole block 33 on one side out of the inner wall of the rectangular groove block 31, thereby removing it from the filling machine 1 for easy maintenance and replacement.
