The turntable 7 is rotationally installed at the bottom of the limiting plate through a shaft rod, and a driving motor 17 is installed on the top of the limiting plate. The output shaft of the driving motor 17 is installed at the center of the top end of the shaft rod; When concentrated cream needs to be filled, first place the filling container on the conveyor belt 1, convey the container through the conveyor belt 1, and drive the shaft rod and the turntable 7 to rotate through the driving motor 17. When the container is placed at the material groove 16, the rotation of the turntable 7 will drive the container to rotate to the filling station.
[0022] Please refer to the appendix Figure 1 - appendix Figure 9 , In a preferred embodiment, the air extraction component includes: an air box 3. The air box 3 is installed on the top of the horizontal side of the U-shaped frame 2, and an air outlet pipe 6 is connected and installed on the side of the air box 3. A first one-way valve is installed on the air outlet pipe 6. A first corrugated pipe 10 connected to the air box 3 is installed at the bottom of the horizontal side of the U-shaped frame 2, and an air inlet pipe 9 is connected to the end of the first corrugated pipe 10. The end of the air inlet pipe 9 passes through the end cap 8, and a second one-way valve is installed on the air inlet pipe 9; Next, the electric telescopic rod 5 drives the end cover 8 to move downward. The downward movement of the end cover 8 drives the slideway 11 to move downward. The downward movement of the slideway 11 drives the L-shaped plate 13 to move downward. The downward movement of the L-shaped plate 13 drives the stopper 21 and the piston rod 20 to move downward. The downward movement of the piston rod 20 drives the piston plate 18 to move downward and causes the third spring rod 19 to generate a tensile force. The downward movement of the piston plate 18 will open the first one-way valve, and the gas inside the air tank 3 will be discharged through the air outlet pipe 6. At this time, the second one-way valve is in a closed state.
[0023] Please refer to the appendix Figure 1 - appendix Figure 9 In a preferred embodiment, a piston plate 18 is slidably arranged inside the air tank 3.

An L-shaped plate 13 is arranged above the slideway 11, and the end of the vertical side of the L-shaped plate 13 is slidably installed inside the slideway 11. A slope is formed at the bottom of the horizontal side of the L-shaped plate 13, and a first spring rod 12 connected to the side surface of the vertical side of the L-shaped plate 13 is installed at the inner end of the slideway 11; As the end cover 8 moves downward, due to the action of the slope on the horizontal side of the L-shaped plate 13, the L-shaped plate 13 will move away from the stopper 21. When the end cover 8 covers the container port, the L-shaped plate 13 and the stopper 21 are separated, and the tensile force generated by the third spring rod 19 will cause the piston plate 18 to move upward. At this time, the second one-way valve is opened, and the gas inside the container enters the air tank 3 through the air inlet pipe 9 and the first corrugated pipe 10, completing the extraction of the gas inside the container and avoiding the occurrence of a large amount of foam during filling.
[0024] Please refer to the appendix Figure 1 - appendix Figure 9 In a preferred embodiment, the filling assembly includes: a barrel body 4, the barrel body 4 is vertically installed at the top of the horizontal side of the U-shaped frame 2, and a second corrugated pipe 23 communicated with the barrel body 4 is installed at the bottom of the horizontal side of the U-shaped frame 2. The end of the second corrugated pipe 23 is communicated and installed with a filling pipe 35, and the end of the filling pipe 35 passes through the end cover 8; The downward movement of the end cover 8 will also drive the reciprocating lead screw 15 to move downward. The downward movement of the reciprocating lead screw 15 drives the second bevel gear 26 to move downward. The downward movement of the second bevel gear 26 drives the collar 28, the rotating rod 24, the first bevel gear 25, the first gear 34 and the filling pipe 35 to move downward through the U-shaped rod 29, which is the first stage of movement. The downward movement of the filling pipe 35 will drive the second spring rod 14 to move downward.
[0025] Please refer to the appendix Figure 3, in a preferred embodiment, a second spring rod 14 is vertically and fixedly installed on the surface of the filling pipe 35, and a pressure relief sink is provided at the top of the end cap 8. The second spring rod 14 is used to block the pressure relief sink; It can block the pressure relief sink when the end cap 8 covers the container port, ensuring the smooth evacuation of the container interior.
[0026] Please refer to the attached Figure 3 - attached Figure 9 , in a preferred embodiment, an impeller 32 is rotatably installed inside the filling pipe 35. A rotating rod 24 is fixed to the side of the impeller 32, and the surface of the impeller 32 is rotatably installed inside the inner wall of the filling pipe 35. A first gear 34 is fixedly installed on the surface of the impeller 32, and a toothed plate 30 is vertically and fixedly installed at the bottom of the horizontal side of the U-shaped frame 2. A plurality of convex teeth 33 evenly distributed in a straight line are hinged to the side of the toothed plate 30 through a one-way elastic hinge. The convex teeth 33 hinged through the one-way elastic hinge only allow the first gear 34 to rotate in one direction; When the first gear 34 moves downward, it will contact the rack. At this time, the first gear 34 will rotate. The rotation of the first gear 34 drives the rotation of the rotating rod 24. The rotation of the rotating rod 24 drives the rotation of the first bevel gear 25. The rotation of the first bevel gear 25 drives the rotation of the second bevel gear 26. Due to the arrangement of the reciprocating lead screw 15, the rotating second bevel gear 26 will move downward. The downward movement of the second bevel gear 26 drives the collar 28, the rotating rod 24, the first bevel gear 25, the first gear 34 and the filling pipe 35 to move downward through the U-shaped rod 29, which is the second stage of movement, so as to realize that when the end cap 8 covers the container, the filling pipe 35 enters the near bottom end of the container, reducing the formation of foam during filling.
[0027] Please refer to the attached Figure 2 - attached Figure 9 , in a preferred embodiment, a first bevel gear 25 is fixedly installed at the end of the rotating rod 24. A second bevel gear 26 is meshed with the side of the first bevel gear 25. An extension plate 31 is fixedly installed on the surface of the end cap 8, and a reciprocating lead screw 15 is vertically and fixedly installed at the top of the extension plate 31. A limiting rod 22 is slidably arranged inside the reciprocating lead screw 15, and the top of the limiting rod 22 is fixedly installed at the bottom of the horizontal side of the U-shaped frame 2. The second bevel gear 26 is threadedly sleeved on the surface of the reciprocating lead screw 15, and an annular groove 27 is provided at the end face of the second bevel gear 26. A collar 28 is rotatably sleeved on the surface of the rotating rod 24, and a U-shaped rod 29 is fixedly installed on the surface of the collar 28. The other end of the U-shaped rod 29 is slidably installed inside the annular groove 27; When filling, the concentrated cream inside the barrel body 4 will enter the container through the second bellows 23 and the filling pipe 35. Then, the impeller 32 inside the filling pipe 35 will rotate. The rotation of the impeller 32 drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the first gear 34 and the first bevel gear 25 to rotate. The rotation of the first bevel gear 25 drives the second bevel gear 26 to rotate. Due to the setting of the reciprocating lead screw 15, the rotating second bevel gear 26 will move upward. The upward movement of the second bevel gear 26 drives the collar 28, the rotating rod 24, the first bevel gear 25, the first gear 34, and the filling pipe 35 to move upward through the U-shaped rod 29 to achieve the progress of the perilla filling. The filling pipe 35 will gradually move upward, reducing the impact force between the liquids during filling. In addition, as the filling pipe 35 moves upward, it drives the second spring rod 14 to move upward. When the filling of the container is completed, the telescopic end of the second spring rod 14 will separate from the pressure relief sink to achieve automatic pressure relief; Finally, the electric telescopic rod 5 drives the end cover 8 and its connecting components to move upward together, and then it can return to the initial state; In summary, by repeating the above steps in sequence, the concentrated cream can be continuously filled. Moreover, a large amount of foam is avoided during filling, ensuring the cleanliness and filling effect of the container during filling, and thus improving the use effect of the equipment.
