One end of the cleaning tube 61 is connected to the cleaning assembly 5 through a hose 62, and the other end is provided with a cleaning nozzle 63 that cooperates with the filling needle 31 of the filling needle assembly 3. The cleaning nozzle 63 is located between the filling needle 31 and the cleaning assembly 5, and between the turntable 2 and the manipulator of the manipulator assembly 4; the cleaning nozzle 63 is arranged one-to-one with the filling needle 31, and a hinged rod 64 is hinged on the cleaning tube 61. The end of the hinged rod 64 away from the cleaning tube 61 is hinged to the cleaning assembly 5. Figure 2 , the filling tray 1 is connected with a lifting mechanism 7, and the lifting mechanism 7 is used to drive the filling tray 1 to rise. In the present invention, the lifting mechanism 7 drives the filling tray 1 to rise, thereby driving the filling needle 31 to rise. When the bottom of the filling needle 31 is higher than the height of the cleaning nozzle 63, the filling needle 31 stops rising. The cleaning component 5 moves upward and drives the cleaning tube 61 to move outward (toward the filling needle 31) through the hinge rod 64. When the cleaning nozzle 63 is located directly below the filling needle 31, the cleaning component 5 stops moving upward. The lifting mechanism 7 drives the filling tray 1 to descend and drives the filling needle 31 to descend. After the filling needle 31 extends into the cleaning nozzle 63, it is tightly sealed with the cleaning nozzle 63. The cleaning component 5 ensures that each filling head pipeline can be reliably cleaned and sterilized through the cleaning nozzle 63. After cleaning, the lifting mechanism 7 drives the filling needle 31 to move upward, and then the cleaning component 5 moves downward to drive the cleaning nozzle 63 to move inward. Finally, the lifting mechanism 7 drives the filling needle 31 to move downward to return the filling needle 31 to the filling station.

[0036] An implementation of the lifting mechanism 7: The lifting mechanism 7 includes: a second annular plate 71, a vertical rod 72 and a lifting assembly 73. The vertical rod 72 is located between two adjacent support plates 53. The second annular plate 71 is arranged below the filling disk 1. One end of the vertical rod 72 passes through the transfer disk 2 and is fixed to the filling disk 1, and the other end is fixed to the second annular plate 71. The outer diameters of the first annular plate 51 and the manifold 52 are both smaller than the inner diameter of the second annular plate 71. The first annular plate 51 and the manifold 52 are both located between the second annular plate 71 and the filling disk 1. The lifting assembly 73 is used to drive the second annular plate 71 to rise and fall. The second annular plate 71 drives the filling disk 1 to rise and fall through the vertical rod 72. The second annular plate 71, the vertical rod 72 and the lifting assembly 73 are all arranged on the outside of the filling machine. This design can effectively avoid affecting the installation and operation of other components of the filling machine and reduce the difficulty of transformation.

[0037] An implementation method of the lifting assembly 73: Figure 8 The lifting assembly 73 includes a plurality of first guide rods 731 that can be lifted and lowered. A clamping block 732 is provided at the upper end of the first guide rod 731. The clamping block 732 is provided with pulleys 733 at the upper and lower ends of the second annular plate 71. The pulleys 733 roll along the second annular plate 71. When the second annular plate 71 rotates with the filling plate 1, the first guide rods 731 are connected to the second annular plate 71 through the pulleys 733. When the lifting assembly 73 is not working, it will not affect the normal operation of the filling plate 1.

[0038] As another embodiment of the present invention: Figure 3 and attached Figure 7 The lifting assembly 73 includes: a lifting motor 734, two base plates 735 and two synchronous shafts 736.

The lead screw 737 is connected to the synchronous shaft 736 through a chain transmission mechanism 738. The two synchronous shafts 736 are connected through a belt transmission mechanism 739. The lifting motor 734 is used to drive a synchronous shaft 736 to rotate, thereby driving the two lead screws 737 to rotate. The lead screw 737 rotates to drive the base plate 735 to rise and fall, thereby driving the first guide rod 731 to rise and fall. The lead screw 737 and the synchronous shaft 736 are both located on the outer side of the second annular plate 71. A first guide rod 731 on the base plate 735 passes through the chain transmission mechanism 738. In this structural design, the lifting motor 734, the bottom plate 735, the synchronous shaft 736, the lead screw 737, the chain transmission mechanism 738 and the belt transmission mechanism 739 are all located outside the filling machine. This design can effectively avoid affecting the installation and operation of other parts of the filling machine and reduce the difficulty of modification.

[0040] In the present invention, when the machine is finished filling and the liquid circulation pipeline needs to be cleaned and sterilized, first, the lifting motor 734 installed in the vertical direction at the bottom of the main machine drives the screw 737 to rotate through the belt transmission mechanism 739 and the chain transmission mechanism 738. The screw 737 rotates and drives the bottom plate 735 to move upward, thereby driving the second annular plate 71 to move upward together with the filling plate 1. The filling plate 1 rises and drives the filling needle assembly 3 to move upward. When the liquid outlet at the lower end of the filling needle 31 is higher than the cleaning nozzle 63; the four lifting motors on the turntable 2 The lowering cylinder 8 acts at the same time, pulling the first annular plate 51 and the manifold 52 upward at the same time. The first annular plate 51 pushes the cleaning guide rod 65 to move outward through the hinge rod 64. The cleaning guide rod 65 drives the cleaning nozzle 63 to move to the bottom of the filling needle 31. The filling needle assembly 3 then moves downward through the lifting motor 734, so that the filling needle 31 is just centered and fully inserted into the cleaning nozzle 63 and reliably sealed, ensuring that each filling head pipeline can be reliably cleaned and sterilized. After completion, it is automatically separated according to the opposite program control. The connection and separation of the pipelines in the entire cleaning and sterilization process are automated, and there is no need for manual clamping and disassembly one by one, which is highly efficient.
