At this time, the power supply can be turned on. When the power supply is turned on, the cylinder 42 is also electrically connected to the power supply. The extension rod 41 can move in the cavity of the cylinder 42 by turning on the power supply of the cylinder 42. First, the cylinder 42 will move the extension rod 41 upward, and the extension rod 41 will drive the piston head 40 to move from the bottom of the cavity of the straw 39 to the top of the cavity of the straw 39. When the piston head 40 moves, the liquid in the cavity of the liquid storage tank 26 will be drawn into the cavity of the straw 39 because of the piston principle, which is connected with the suction groove 38 and the suction port 35 and is also connected with the infusion tube 27.

The device can also increase the air tightness of the device by installing a sealing ring at each connection point, so compared with the prior art, the working efficiency of this solution is higher.

[0036] like Figure 1 and Figure 2As shown, the filling structure also includes a piston head 40, which slides up and down in the cavity of the straw 39. The top of the processing table 20 is rotatably connected to a turntable 22, and the wall of the turntable 22 is fixedly connected to a clamping plate 23.

[0038] In summary, by providing a rotatable turntable 22, the clamping plate 23 can be driven to rotate and fill the containers clamped by its wall surface, so that the machine can perform filling without stopping, and the working efficiency of the device is further improved.

[0039] Working principle: first add the liquid medicine to be filled into the cavity of the liquid storage tank 26, and clamp the container of the medicine in the circular groove on the wall of the splint 23, then the power supply can be turned on, when the power supply is turned on, the cylinder 42 is also electrically connected to the power supply, and the extension rod 41 can move in the cavity of the cylinder 42 by turning on the power supply of the cylinder 42, first the cylinder 42 will move the extension rod 41 upward, the extension rod 41 will drive the piston head 40 to move from the bottom of the cavity of the straw 39 to the top of the cavity of the straw 39, when the piston head 40 moves, the liquid in the cavity of the liquid storage tank 26 will be drawn into the cavity of the straw 39 because of the piston principle, which is connected through the suction groove 38 and the suction port 35 and is also connected with the infusion tube 27, at this time, the hydraulic rod 24 will extend downward, when the hydraulic rod 24 is extended, it will drive the joint bar 25 to move downward at the same time, the joint bar 25 will drive the infusion head 30 to enter the cavity of the container, the infusion head 30 will drive The conversion column 31 moves at the same time, and the conversion column 31 will drive the connecting plate 34 to move at the same time. When moving downward, the connecting plate 34 will change the state in which the suction port 35 and the suction groove 38 are connected to each other to a state in which the suction groove 38 is blocked. After the conversion column 31 moves downward, the state in which the outlet port 37 in the cavity of the conversion block 32 is blocked will be changed to a state in which the infusion port 33 and the outlet port 37 are overlapped and connected. At this time, the extension rod 41 is pushed downward by the cylinder 42, and the piston head 40 will inject the liquid in the cavity of the suction tube 39 into the infusion head 30 through the outlet port 37 during movement, and then enter the container cavity to complete the filling of the liquid.
