The other ends of the two first guide rods 306 are slidably connected to the first guide sliding holes opened at the corresponding positions of the first supports 1a. The output ends of the PLC controller 9 are respectively electrically connected to the input ends of the first motor 303 and the second electric telescopic rod 305.

[0041] The spiral transmission assembly 3 further includes a bottom support structure 302 disposed below the spiral transmission rib plate 301. The bottom support structure 302 includes a bottom support plate 302a. The outer shape of the bottom support plate 302a is rectangular. The length direction of the bottom support plate 302a is consistent with the axial direction of the spiral transmission rib plate 301.

Further, the outer shape of the filling barrel 2 is cylindrical. The tube axis of the milk liquid adding pipe 2a is inclined with respect to the central axis of the filling barrel 2. The milk outlet of the milk liquid adding pipe 2a faces obliquely upward inside the filling barrel 2. When the milk liquid adding pipe 2a adds the liquid into the filling barrel 2, the milk inside the filling barrel 2 will be impacted, which plays a certain role in preventing precipitation, and can make the milk inside the filling barrel 2 rotate in one direction, cooperating with the stirring assembly 7 to realize the segmentation and stirring of the milk inside the filling barrel 2, greatly improving the anti-precipitation effect of the milk. Through the above specific structural design, when the transmission belt 5c moves and transmits the milk storage container, the limit baffle 5b can block and limit the milk storage container, facilitating the positioning, lifting and transferring of the lifting and transferring assembly 6.

[0043] The lifting and transfer assembly 6 includes an outer sleeve ring 601. The outer shape of the outer sleeve ring 601 is circular. A turntable 608 is rotatably connected inside the outer sleeve ring 601 through a bearing.

[0044] A first gear 603 is fixedly arranged on the outer side of the upper part of the turntable 608. A second gear 605 is meshed and connected to one side of the first gear 603. A second motor 609 for driving the second gear 605 to rotate is fixedly arranged on the upper side of the outer sleeve ring 601.

The output end of the PLC controller 9 is electrically connected to the input ends of the first cylinder 602, the second cylinder 604, and the second motor 609 respectively.

[0045] The filling barrel 2 has a cylindrical shape. The inside of the filling barrel 2 is hollow and the bottom is in the shape of a frustum of a cone with an upper wide and lower narrow shape. The stirring assembly 7 includes a third motor 7a fixedly arranged on the top of the filling barrel 2. The output shaft end of the third motor 7a is fixedly connected to a rotating shaft 7b. The central axis of the rotating shaft 7b and the central axis of the filling barrel 2 are coaxial. Two or more scraping bottom plates 7d are fixedly connected to the bottom end of the rotating shaft 7b and are evenly distributed at equal angles around its axis. A plurality of stirring rods 7c are fixedly connected to the rotating shaft 7b above the scraping bottom plates 7d. The output end of the PLC controller 9 is electrically connected to the input end of the third motor 7a.

[0046] Working principle:

[0047] During use, one of the two transfer structures 5 is used to transfer an empty milk storage container to one end of the spiral transfer assembly 3. After the empty milk storage container is equidistantly transferred to the perfusion pipe structure 8 by the spiral transfer assembly 3 for perfusion, the other of the two transfer structures 5 is used to transfer the filled milk storage container to the next process for capping;

[0048] When the lifting and transferring component 6 between the spiral transmission component 3 and the transmission structure 5 performs lifting and transferring, the output shaft of the second motor 609 of the lifting and transferring component 6 rotates. The rotation of the output shaft of the second motor 609 drives the second gear 605 to rotate. The rotation of the second gear 605 drives the engaged first gear 603 to rotate. The rotation of the first gear 603 drives the turntable 608 to rotate. The rotation of the turntable 608 drives the second cylinder 604 fixedly arranged thereon to rotate. Each second cylinder 604 is a lifting station. When one of the second cylinders 604 rotates to be located above the milk storage container of the transmission structure 5, the push rod head end of the second cylinder 604 extends to drive the U-shaped clamp 606 to move downward. When the bottle mouth of the milk storage container is located between the two bottle mouth clamps 607, the push rods of the two first cylinders 602 extend, so as to drive the bottle mouth clamps 607 to approach each other, realizing the clamping and positioning of the bottle mouth of the milk storage container. Then, the push rod of the second cylinder 604 retracts, driving the milk storage container to move upward. Then, the second motor 609 drives the bottle mouth clamp 607 to clamp the milk storage container and rotate it to the spiral transmission rib 301. The push rod of the second cylinder 604 extends to place the milk storage container down again. Then, the push rod of the first cylinder 602 retracts, and the two bottle mouth clamps 607 move away from each other, realizing the loosening of the bottle mouth of the milk storage container. The spiral transmission component 3 can continue to transmit the milk storage container;

[0049] When the spiral transmission component 3 transports the milk storage container, the milk storage containers are distributed between the pitches of the spiral transmission rib plates 301 to achieve equidistant transmission of the milk storage containers, so as to cooperate with the perfusion pipe structure 8 to achieve positioning filling of the milk storage containers. After filling, it is transported by the spiral transmission component 3 to another transmission structure 5 for transmission to the next process. The output shafts of the first motors 303 of the two spiral transmission components 3 rotate simultaneously, thereby driving the two spiral transmission rib plates 301 to rotate simultaneously. The simultaneous rotation of the two spiral transmission rib plates 301 realizes the transmission drive of the milk storage containers. At this time, the limit retaining rod 307 can limit the two side edges of the milk storage container to realize the moving and guiding transmission of the milk storage container and prevent the milk storage container from tipping over. The bottom support structure 302 can realize sliding support for the bottom of the milk storage container. When the milk storage container moves to directly below the perfusion pipe structure 8, the push rod of the first electric telescopic rod 302b extends to drive the bottom support rod 302e to move upward. The bottom support rod 302e moves upward and protrudes through the upper port of the rod passing groove 302f to lift the milk storage container, so that the lower end of the perfusion pipe 8a is inserted into the bottle mouth of the milk storage container. The PLC controller 9 controls the opening of the solenoid valve 8c to achieve filling of the milk storage container. Further, a pressure sensor 8e is provided on the lower side of the slip ring 8d. When the pressure sensor 8e detects the abutting pressure of the bottle mouth of the milk storage container, it can realize the feedback control of the PLC controller 9 on the solenoid valve 8c. The solenoid valve 8c uses an electromagnetic flowmeter, which has both on-off control function and flow measurement function. After perfusion is completed, the first electric telescopic rod 302b of the bottom support structure 302 drives the bottom support rod 302e to retract, and then the spiral transmission component 3 continues to drive the milk storage container to move.
