[0038] After setting the distance between the second clamping plate 209 and the second partition belt according to the diameter of the wine bottle, start the third motor 201 to drive the second driving roller 203 through the synchronous belt and the synchronous pulley, and then drive the second conveyor belt 204 and the multiple second driven rollers to rotate well, and convey the wine bottles filled by the filling mechanism 3 to other equipment for subsequent processes.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 : At the upper ends of the two columns 301, a cross plate 303 is fixedly arranged. At the center of the lower end of the cross plate 303, an electric cylinder 304 is fixedly arranged. At the lower end of the telescopic end of the electric cylinder 304, a pressing plate 305 is fixedly arranged. At the positions near both sides of the lower end of the pressing plate 305, upper covers 306 are fixedly arranged. At the positions of the four peripheral edges of the lower ends of the two upper covers 306, rotating rings 307 are rotatably arranged. Between the outer sides of the two rotating rings 307 and the inner sides of the two columns 301, infusion tubes 309 are fixedly arranged through them. At the positions of the four peripheral edges of the lower ends of the two rotating rings 307, lower bottoms 308 are rotatably arranged. At the lower ends of the two lower bottoms 308, rotating shafts 314 are slidably arranged. At the middle positions of the shafts of the two rotating shafts 314, bottle clamping rings 316 are fixedly arranged through them. At the positions above the two bottle clamping rings 316 and at the middle positions of the shafts of the two rotating shafts 314, a plurality of infrared sensors 313 are fixedly arranged in a centrosymmetric manner. At the middle position of the upper end of the bottom plate 4 and at the rear, two fifth motors 315 are fixedly arranged in an axisymmetric manner respectively. At the positions near the lower parts of the shafts of the two rotating shafts 314, they are respectively connected to the output ends of the two fifth motors 315 through synchronous pulleys and synchronous belts;

[0040] At the positions near the lower ends on the sides of the two lower bottoms 308, a plurality of filling pipes 310 are fixedly arranged in a centrally symmetric manner through, and solenoid valves 312 are threadedly sleeved at the lower ends of the plurality of filling pipes 310, and nozzles 311 are threadedly sleeved at the lower ends of the plurality of solenoid valves 312. The upper positions inside the two support columns 301 are designed to be hollow, and liquid injection ports 302 are fixedly arranged through the outer sides of the two support columns 301 at the upper positions.

[0041] A vertical rod 320 is fixedly arranged at the central position of the lower end of the pressing plate 305.

[0042] Specifically, during use, the fifth motor 315 drives the rotating shaft 314 and the bottle clamping ring 316 to rotate well through a synchronous belt and a synchronous pulley. The wine bottles conveyed by the feeding mechanism 1 are squeezed and guided by the first guide block 317 to the bayonets on the bottle clamping ring 316. After the infrared sensor 313 corresponding to the bayonet detects the wine bottle, it sends a signal to the PLC module built in the device. The PLC module opens the solenoid valve 312 corresponding to the bayonet to fill the wine bottle at the corresponding bayonet through the filling pipe 310 and the nozzle 311. The flowmeter built in the filling pipe 310 is used to control the amount of the filled wine liquid. When the set value is reached, the solenoid valve 312 is closed. The external wine storage device is connected through the liquid injection port 302 fixedly arranged through the outer side of the support column 301 at the upper position, and flows into the temporary wine storage space formed by the upper cover 306, the rotating ring 307 and the lower bottom 308 through the liquid infusion pipe 309. The rotating ring 307 is respectively rotatably connected to the upper cover 306 and the lower bottom 308 well, and the lower bottom 308 is slidably connected well to the upper end opening of the rotating shaft 314 through the lower end insertion block.

[0043] When the filled wine bottle rotates with the bottle clamping ring 316 to contact the second guide block 318, it is squeezed and guided by the second guide block 318 and falls off from the bayonet on the bottle clamping ring 316 to the second conveyor belt 204 of the return material mechanism 2. When the filling work is completed, there is a certain amount of residual wine liquid in the nozzle 311. According to actual needs, the user can start the electric cylinder 304 to drive the pressing plate 305 to move up and down. Springs are fixedly arranged between the lower ends of the two lower bottoms 308 and the bottom surfaces of the upper end openings of the two rotating shafts 314. Then, the upper cover 306, the rotating ring 307 and the lower bottom 308 drive the plurality of nozzles 311 to shake repeatedly in the vertical direction, and the residual wine liquid in the nozzles 311 is shaken out well to avoid affecting the quality of the next filling.

[0044] Working principle: When in use, according to actual needs, start the second motor 102 to drive the rotation of the four first lead screws 106 through the five first drive wheels 111 and the first drive belt 110. The two first sliders 107 sleeved on both sides of each first lead screw 106 with opposite threads move closer to or away from each other, driving the two first U-shaped rods 108 connected thereto to move closer to or away from each other, so that the two first clamping plates 109 connected to the first U-shaped rods 108 on both sides approach or move away from the first partition belt vertically fixed at the middle position of the outer surface of the first conveyor belt 104, so as to well adapt to wine bottles of different diameters. Each return mechanism 2 starts the fourth motor 202 to drive the rotation of the four second lead screws 206 through the five second drive wheels 211 and the second drive belt 210. The second sliders 207 sleeved on the threads of each second lead screw 206 move closer to or away from the inside, driving the second U-shaped rods 208 connected thereto to move closer to or away from the inside, so that the second clamping plates 209 connected to the four second U-shaped rods 208 approach or move away from the second partition belt vertically fixed at the outer edge position of the second conveyor belt 204, so as to well adapt to wine bottles of different diameters. After setting the distance between the two first clamping plates 109 and the first partition belt according to the diameter of the wine bottle, start the first motor 101 to drive the first driving roller 103 through the synchronous belt and the synchronous pulley, and then drive the first conveyor belt 104 and multiple first driven rollers to rotate well, and convey the wine bottles to be filled to the filling mechanism 3 well;

[0045] Secondly, start the fifth motor 315 to drive the rotation of the rotating shaft 314 and the bottle clamping ring 316 well through the synchronous belt and the synchronous pulley. The wine bottles conveyed by the feeding mechanism 1 are squeezed and guided by the first guide block 317 to the bayonet on the bottle clamping ring 316. After the infrared sensor 313 corresponding to the bayonet detects the wine bottle, it sends a signal to the PLC module built in the device. The PLC module opens the electromagnetic valve 312 corresponding to the bayonet to fill the wine bottle corresponding to the bayonet through the filling pipe 310 and the nozzle 311. The flow meter built in the filling pipe 310 is used to control the amount of the filled wine liquid. When the set value is reached, the electromagnetic valve 312 is closed. Connect the external wine storage device through the liquid injection port 302 fixedly arranged through the upper position on the outer side of the support column 301, and flow into the temporary wine storage space formed by the upper cover 306, the rotating ring 307 and the lower bottom 308 through the liquid delivery pipe 309. The rotating ring 307 is respectively rotatably connected to the upper cover 306 and the lower bottom 308 well, and the lower bottom 308 is slidably connected to the upper end opening of the rotating shaft 314 through the lower end insertion block well. Multiple strip-shaped protrusions are fixedly arranged on the column surface of the insertion block to ensure that the lower bottom 308 rotates well with the rotating shaft 314 without affecting the rotating ring 307 fixedly connected to the support column 301 through the liquid delivery pipe 309;

[0046] Then, when the filled wine bottle rotates with the bottle clamping ring 316 to contact the second guide block 318, it is squeezed and guided by the second guide block 318, falls off from the bayonet on the bottle clamping ring 316 onto the second conveyor belt 204 of the return material mechanism 2. After setting the distance between the second clamping plate 209 and the second separation belt according to the diameter of the wine bottle, the third motor 201 is started to drive the second driving roller 203 through the synchronous belt and synchronous pulley, and then drive the second conveyor belt 204 and multiple second driven rollers to rotate well, and transfer the wine bottles filled by the filling mechanism 3 to other equipment for subsequent processes;

[0047] Finally, when the filling work is completed, there is a certain amount of residual wine liquid in the nozzle 311.
