[0056] The sterile protection part is arranged in the fixed sleeve 501, and the sterile protection part comprises a circuit board 504 and ultraviolet sterilization lamp beads 505; the circuit board 504 is annular, and the circuit board 504 is fixedly laid on the inner wall of the fixed sleeve 501, and a plurality of ultraviolet sterilization lamp beads 505 are uniformly installed on the circuit board 504.

[0057] The telescopic material tube 5 is driven by the lifting mechanism 2 to make the injection tube 502 extend downward from the fixed sleeve 501 or reset and retract into the fixed sleeve 501.

[0058] The fixed sleeve 501 is fixedly installed on the rack 1 through the fixed frame 3, and its position is fixed; during the filling process, the lifting mechanism 2 provides driving to make the injection tube 502 move downward for insertion into the bottle mouth 8 of the packaging container, as Figure 8After filling is completed, the lifting mechanism 2 moves the injection tube 502 upward, so that the bottom end of the injection tube 502, that is, the discharge port, moves into the fixed sleeve 501, as shown.

[0060] The circuit board 504 provides a circuit for connecting the ultraviolet germicidal lamp beads 505 and is also connected to an external power supply.

[0061] like Figure 3 As shown, the filling assembly 4 includes a barrel 403 fixedly mounted to the bottom surface of the movable plate 204 and a second cylinder 401, the interior of the barrel 403 is cooperated with and connected to a piston 404, a cavity is formed between the bottom surface of the piston 404 and the inner wall of the barrel 403, a first one-way valve 405 and a second one-way valve 406 are fixedly mounted on the bottom of the barrel 403, the top end of the first one-way valve 405 and the top end of the second one-way valve 406 are both connected to the cavity, the second cylinder 401 is fixedly mounted to the top surface of the movable plate 204, the output shaft end of the second cylinder 401 is fixedly connected to the piston 404; a rubber top pad 402 is fixedly mounted on the top of the second cylinder 401.

[0062] The second one-way valve 406 is connected to the feed pipe 7; the feed pipe 7 includes a connecting pipe 701, a three-way pipe 702 and a cross pipe 703; one end of the connecting pipe 701 is connected to the second one-way valve 406, and the other end of the connecting pipe 701 is connected to the cross pipe 703 through the three-way pipe 702.

[0063] The transverse pipe 703 passes through the side groove 101 provided on the side wall of the frame 1 , and a joint 704 is installed at one end of the transverse pipe 703 away from the tee pipe 702 .

[0064] The cavity is used to store sterile liquid food, and the filling process is as follows: after the injection tube 502 is inserted into the bottle mouth 8 of the packaging container, the second cylinder 401 is extended to drive the piston 404 downward. The piston 404 pushes the liquid in the cavity, and the liquid enters the injection tube 502 through the first one-way valve 405, is discharged through the injection tube 502, and is filled into the packaging container. After the filling is completed, the injection tube 502 is reset upward, and the second cylinder 401 simultaneously contracts, driving the piston 404 upward, allowing the external sterile liquid food to enter the cavity through the feed pipe 7 and the second one-way valve 406 for the next filling.

[0065] The feeding pipe 7 is used to connect an external feeding device, such as a tank containing a sterile liquid food, and the bottom of the tank is provided with a pipe opening connected with the joint 704 of the feeding pipe 7.

[0066] As shown in Figure 2 、 Figure 3 、 Figure 5 The cleaning gas injection mechanism 6 includes a contraction air bag 601, an air inlet box 602, a first air pipe 603, a second air pipe 604, a third one-way valve 605, an interface 606, an air inlet 607, and a fourth one-way valve 609. The contraction air bag 601 is arranged between the top inner wall of the rack 1 and the top surface of the movable plate 204. The top surface of the contraction air bag 601 is fixedly connected with the top inner wall of the rack 1, and the bottom surface of the contraction air bag 601 is fixedly connected with the top surface of the movable plate 204. The bottom of the contraction air bag 601 is provided with the third one-way valve 605 and the interface 606. The third one-way valve 605 is connected with one end of the first air pipe 603. The other end of the first air pipe 603 is in communication with the bottom of the air inlet box 602. The air inlet box 602 is provided with the air inlet 607 at the top. The interface 606 is connected with one end of the second air pipe 604. The other end of the second air pipe 604 is connected with the fourth one-way valve 609. The fourth one-way valve 609 is arranged at the top side of the injection pipe 502.

[0067] The air inlet box 602 is internally provided with a filter 608. The top surface of the air inlet box 602 is fixedly connected with the bottom surface of the movable plate 204.

[0068] During the upward resetting of the grouting pipe, the cleaning gas injection mechanism 6 injects clean gas flow into the injection pipe 502 to blow the liquid adhered to the inner wall of the injection pipe 502 into the bottle opening 8 of the packaging container.

[0069] Specifically, when the grouting pipe moves downward with the movable plate 204, the movable plate 204 pulls the bottom of the contraction air bag 601. The top of the contraction air bag 601 is fixedly connected with the top of the rack 1 and cannot move. Therefore, the volume of the contraction air bag 601 increases, and external air enters the contraction air bag 601. Specifically, the external air enters the air inlet box 602 through the air inlet 607, is filtered by the filter 608, and then enters the contraction air bag 601 through the first air pipe 603 and the third one-way valve 605. The above process is used to compensate the clean gas in the contraction air bag 601.

[0070] When the grouting pipe moves up with the movable plate 204, the movable plate 204 pushes the bottom of the contraction air bag 601 upwards, and the top of the contraction air bag 601 is fixed on the top of the frame 1 and cannot move, so that the contraction air bag 601 is compressed, the air in the contraction air bag 601 enters the top of the grouting pipe in sequence through the interface 606, the second air pipe 604 and the fourth one-way valve 609, and then is discharged from the bottom of the grouting pipe, when the air flow blows in the grouting pipe, the liquid adhered to the wall of the grouting pipe is blown down by the air flow, so that adhesion is avoided.

[0071] In the above, the cleaning air injection mechanism 6 injects clean air flow into the grouting pipe, without additional driving components, and only needs to provide driving force by the up-down movement of the movable plate 204.

[0072] The filter 608 can be multiple, and preferably high-efficiency filter 608, activated carbon filter 608.

[0073] The contraction air bag 601 can be in a corrugated type, and specifically a rubber corrugated pipe with both ends closed.

[0074] The utility model is not limited to the above-mentioned embodiment, no matter makes any change in its shape or structure, all falls in the protection scope of the utility model. The protection scope of the utility model is defined by the appended claims, and the person skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the utility model, but these changes and modifications all fall into the protection scope of the utility model.
