[0020] like Figure 3-Figure 6 As shown, the main mechanism also includes a plurality of guide posts 118 fixedly mounted on the outer shell 101, and the sliding frame 117 slides along the guide posts 118. The outer shell 101 is fixedly mounted with a motor 102, and the outer shell 101 is rotatably mounted with a continuous gear 111. The motor 102 drives the continuous gear 111 to rotate through a belt transmission, and the continuous gear 111 drives the internal gear 112 to rotate through a belt transmission.

[0021] like Figure 3-Figure 6As shown, a bidirectional screw rod 104 and a rotating column 103 are rotatably installed on the outer shell 101, a moving block 105 is slidably installed on the outer shell 101, and the moving block 105 and the bidirectional screw rod 104 form a threaded transmission. A moving gear 106 is slidably installed on the rotating column 103, and the continuous gear 111 drives the rotating column 103 to rotate through a belt transmission, and the rotating column 103 drives the bidirectional screw rod 104 to rotate through a gear transmission.

[0022] like Figure 3-Figure 6 As shown, a rear docking gear 107 and a front docking gear 108 are rotatably mounted on the housing 101 . The front docking gear 108 drives the central gear 109 to rotate via a belt transmission, and the rear docking gear 107 drives the rotating frame column 113 to rotate via a belt transmission.

[0023] The motor 102 drives the continuous gear 111 to rotate through the transmission belt, and the continuous gear 111 drives the internal gear 112 to rotate through the transmission belt. The continuous gear 111 drives the rotating column 103 to rotate through the transmission belt. The rotating column 103 drives the bidirectional screw rod 104 to rotate through the gear transmission. The rotation of the bidirectional screw rod 104 drives the moving block 105 to slide along the housing 101. The moving block 105 drives the moving gear 106 to slide along the rotating column 103. The rotating column 103 drives the moving gear 106 to rotate, and the moving gear 106 moves toward the front docking gear 108. When the moving block 105 drives the moving gear 106, the moving gear 106 moves toward the front docking gear 108. When the gear 106 reaches the front docking gear 108, the moving gear 106 drives the front docking gear 108 to rotate, and the front docking gear 108 drives the central gear 109 to rotate through the belt drive, and the central gear 109 drives the central sliding shaft 110 to rotate. The central sliding shaft 110 performs a spiral motion under the cooperation of the convex ball 115 and the bidirectional internal thread of the internal bidirectional threaded cylinder 116, thereby driving the sliding frame 117 to slide along the guide column 118 toward the housing 101. When the moving gear 106 continues to move along the rotating column 103, the moving gear 106 will disengage from the front docking gear 108. At this time The sliding frame 117 just moves to the innermost side, at this time, loading, coating, unloading and cleaning of the cartridge 201 are carried out. Under the action of the bidirectional external thread of the bidirectional screw 104, when the moving block 105 moves to the extreme position, it starts to move in the opposite direction, and then the moving gear 106 is engaged with the front docking gear 108 again. At this time, the front docking gear 108 drives the continuous gear 111 to rotate, thereby driving the sliding frame 117 to move in the direction away from the housing 101. When the moving gear 106 is disengaged from the front docking gear 108, the sliding frame 117 moves to the outermost side, and then the moving block 105 is moved to the outermost side. 105 continues to move with the moving gear 106. When the moving gear 106 is engaged with the rear docking gear 107, the moving gear 106 drives the rear docking gear 107 to rotate. The rear docking gear 107 drives the turntable column 113 and the turntable 114 to rotate through the belt drive. When the moving block 105 and the moving gear 106 move to the extreme position, they start to move in the opposite direction. When the moving gear 106 is disengaged from the rear docking gear 107, the turntable 114 rotates just one-sixth of a circle. Then the moving block 105 continues to move the moving gear 106 toward the front docking gear 108, and so on.

[0024] like Figure 7 、 Figure 8 As shown, the circulation mechanism includes a cartridge 201 rotatably mounted on a rotating frame 114, a self-rotating gear 202 and a transfer gear 203. The self-rotating gear 202 is fixedly mounted on one end of the cartridge 201. The self-rotating gear 202 is engaged with the transfer gear 203. The transfer gear 203 is engaged with the internal gear 112. A plurality of holes are provided on the cartridge 201.

[0025] The rotating rack 114 rotates one-sixth of a circle each time, so that the cartridge 201 switches between various working positions. The rotation of the internal gear 112 drives the intermediate gear 203 to rotate, and drives the cartridge 201 to rotate through the self-rotating gear 202.

[0026] like Figures 9-13 As shown, the operating mechanism includes a fan 301 fixedly mounted on the housing 101, a heating plate 302 and a powdered sugar box 304, the heating plate 302 is located below the fan 301, an air guide plate 316 is installed in the housing 101, and an induced draft fan 303 is provided on the housing 101.

[0027] like Figures 9-13 As shown, the coating module includes a powdered sugar tube 305 fixedly mounted on the powdered sugar box 304, and a nozzle 306 fixedly mounted on the powdered sugar tube 305. The nozzle 306 is fixedly mounted on the sliding frame 117. When the sliding frame 117 moves to the innermost side, the nozzle 306 is inserted into the corresponding cartridge 201.

[0028] like Figures 9-13 As shown, the feeding module includes a feeding tube 313 fixedly mounted on the outer shell 101, a pushing tube 311 and a pushing plate 312 fixedly mounted on the sliding frame 117, a docking pushing plate 314 slidingly mounted in the feeding tube 313, a feeding hole is provided on the docking pushing plate 314, a compression spring 315 is provided between the docking pushing plate 314 and the feeding tube 313, a slope is provided in the pushing tube 311, and in the initial state, the docking pushing plate 314 closes the bottom of the feeding tube 313; the discharging module includes a discharging box 310 fixedly mounted on the sliding frame 117, and the opening of the discharging box 310 faces upward.

[0029] like Figures 9-13 As shown, the cleaning module includes a cleaning box 307 fixedly mounted on the sliding frame 117, and a water inlet 308 and a water outlet 309 are provided on the outer shell 101. The water inlet 308 is connected to an external water source. When the sliding frame 117 moves to the innermost side, the cleaning box 307 is sleeved on the outside of the corresponding cartridge 201.

[0030] When the sliding frame 117 moves to the innermost side, the three nozzles 306 are inserted into the corresponding cartridges 201, the cleaning box 307 is inserted into the outer side of the outward-facing cartridge 201, and the cartridge 201 is wrapped therein, and the discharge box 310 is inserted into the corresponding cartridge 201. When the sliding frame 117 moves inward, the push plate 312 pushes the docking push plate 314 to slide in the feed pipe 313, and the compression spring 315 is compressed. The medicine placed in the feed pipe 313 falls into the push tube 311 through the feed hole on the docking push plate 314, and the sliding frame 117 pushes the push tube 311 to dock with the cartridge 201, and the medicine slides into the cartridge 201 along the slope of the push tube 311; through the powdered sugar box 304, the powdered sugar tube 305 and the nozzle 306 sprays powdered sugar into the three medicine cartridges 201 and discharges air through the fan 301. After being heated by the heating plate 302, the hot air is guided by the air guide plate 316 and exhausted by the induced draft fan 303 to blow the hot air into the three medicine cartridges 201 undergoing coating. With the rotation of the medicine cartridge 201, the hot air melts the powdered sugar onto the medicine and completes the coating. After the medicine has undergone three layers of coating, it arrives at the discharge box 310. The medicine cartridge 201 rotates and drops the coated medicine into the discharge box 310. When the subsequent sliding rack 117 moves to the outermost side, the medicine in the discharge box 310 is manually taken out. Water enters the water inlet 308, and the water flow rinses the medicine cartridge 201 in the cleaning box 307. The rinsed water is discharged from the water outlet 309.

[0031] When the sliding frame 117 moves to the innermost side, the rotating frame 114 does not rotate, the medicine enters the cartridge 201 through the feeding module, the three coating modules coat the medicine, the discharging module takes out the coated medicine, and the cleaning module cleans the cartridge 201 that has just been discharged. Then the sliding frame 117 moves to the outermost side, and the rotating frame 114 still does not rotate. Then the rotating frame 114 rotates one-sixth of a circle, and the sliding frame 117 does not move, driving all the cartridges 201 to rotate one-sixth of a circle and enter the next workstation, and repeating this process.

[0032] like Figures 1-13 As shown, a coating method of a high-efficiency sugar coating film coating machine for drug processing, the steps are as follows: S1. The drug is placed into the circulation mechanism through the feeding module, and the circulation mechanism rotates one-sixth of a circle to drive the drug to the next station; S2. The drug is coated by three coating modules; S3. The coated drug is removed through the discharging mechanism; S4. Clean the flow module through the cleaning module.

[0033] The working principle of a high-efficiency sugar coating film coating machine for drug processing disclosed by the present invention is as follows: The motor 102 drives the continuous gear 111 to rotate through the transmission belt, and the continuous gear 111 drives the internal gear 112 to rotate through the transmission belt. The continuous gear 111 drives the rotating column 103 to rotate through the transmission belt. The rotating column 103 drives the bidirectional screw rod 104 to rotate through the gear transmission. The rotation of the bidirectional screw rod 104 drives the moving block 105 to slide along the housing 101. The moving block 105 drives the moving gear 106 to slide along the rotating column 103. The rotating column 103 drives the moving gear 106 to rotate, and the moving gear 106 moves toward the front docking gear 108. When the moving block 105 brings the moving gear 106 to the front docking gear 108, the moving block 105 drives the moving gear 106 to rotate. The gear 106 drives the front docking gear 108 to rotate, and the front docking gear 108 drives the center gear 109 to rotate through the belt drive, and the center gear 109 drives the center slide shaft 110 to rotate. The center slide shaft 110 performs a spiral motion under the cooperation of the convex ball 115 and the bidirectional internal thread of the internal bidirectional threaded cylinder 116, thereby driving the sliding frame 117 to slide along the guide column 118 toward the shell 101. When the moving gear 106 continues to move along the rotating column 103, the moving gear 106 is disengaged from the front docking gear 108. At this time, the sliding frame 117 just moves to the innermost side, for drug loading, coating, unloading and cleaning of the cartridge 201. When the moving frame 117 moves to the innermost side, the three nozzles 306 are inserted into the corresponding cartridges 201, the cleaning box 307 is inserted into the outer side of the outward-facing cartridge 201 and wraps the cartridge 201 therein, and the discharge box 310 is inserted into the corresponding cartridge 201. When the sliding frame 117 moves inward, the push plate 312 pushes the docking push plate 314 to slide in the feed pipe 313, and the compression spring 315 is compressed. The medicine placed in the feed pipe 313 falls into the push-in tube 311 through the feed hole on the docking push plate 314. The sliding frame 117 pushes the push-in tube 311 to dock with the cartridge 201, and the medicine slides into the cartridge 201 along the slope of the push-in tube 311. 1; powdered sugar is sprayed into the three medicine cartridges 201 through the powdered sugar box 304, the powdered sugar tube 305 and the nozzle 306, and the air is discharged by the fan 301. After being heated by the heating plate 302, the hot air is guided by the air guide plate 316 and extracted by the induced draft fan 303 to blow the hot air into the three medicine cartridges 201 undergoing coating. With the rotation of the medicine cartridge 201, the hot air melts the powdered sugar onto the medicine, completing the coating; after the medicine has been coated with three layers, it reaches the discharge box 310, and the medicine cartridge 201 rotates to drop the coated medicine into the discharge box 310. When the subsequent sliding rack 117 moves to the outermost side, the medicine in the discharge box 310 is manually taken out;Water enters the water inlet 308, and the water flow rinses the cartridge 201 in the cleaning box 307. The rinsed water is discharged from the water outlet 309. Under the action of the bidirectional external thread on the bidirectional screw rod 104, when the moving block 105 moves to the extreme position, it starts to move in the opposite direction, and the moving gear 106 is meshed with the front docking gear 108 again. The front docking gear 108 drives the continuous gear 111 to rotate, driving the sliding frame 117 to move in the direction away from the housing 101. When the moving gear 106 is disengaged from the front docking gear 108, the sliding frame 117 moves to the outermost side, and then the moving block 105 continues to move with the moving gear 106. When the moving gear 106 is meshed with the rear docking gear 107 When the moving gear 106 drives the rear docking gear 107 to rotate, the rear docking gear 107 drives the turret column 113 and turret 114 to rotate via the belt drive. When the moving block 105 and the moving gear 106 move to the limit position, they begin to move in the opposite direction. When the moving gear 106 disengages from the rear docking gear 107, the turret 114 rotates exactly one-sixth of a circle. Each time the turret 114 rotates one-sixth of a circle, the cartridge 201 switches between various workstations. The rotation of the internal gear 112 drives the intermediate gear 203 to rotate, thereby driving the cartridge 201 to rotate via the self-rotating gear 202. Then the moving block 105 continues to drive the moving gear 106 toward the front docking gear 108, and this reciprocating process continues.

[0034] When the sliding frame 117 moves to the innermost side, the rotating frame 114 does not rotate, the medicine enters the cartridge 201 through the feeding module, the three coating modules coat the medicine, the discharging module takes out the coated medicine, and the cleaning module cleans the cartridge 201 that has just been discharged. Then the sliding frame 117 moves to the outermost side, and the rotating frame 114 still does not rotate. Then the rotating frame 114 rotates one-sixth of a circle, and the sliding frame 117 does not move, driving all the cartridges 201 to rotate one-sixth of a circle and enter the next workstation, and repeating this process.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
