[0037] As Figures 1 to 5As shown, the filling device provided in the embodiment includes a material cylinder 10, a filling piece 20 and a sliding sleeve 30. The material cylinder 10 has a containing cavity 11. The filling piece 20 is fixedly connected to the bottom wall of the material cylinder 10, and one end of the filling piece 20 is located in the containing cavity 11, and the other end of the filling piece 20 extends out of the material cylinder 10. The filling piece 20 is provided with a filling channel 211, which can communicate the containing cavity 11 with the outside. The sliding sleeve 30 is slidingly arranged on the outer peripheral wall of the filling piece 20. The sliding sleeve 30 is provided with a transition cavity 31, which communicates with the filling channel 211. The side wall of the sliding sleeve 30 is provided with a flow port 32. The transition cavity 31 communicates with the containing cavity 11 through the flow port 32. The sliding sleeve 30 has a feeding position and a discharging position. When the sliding sleeve 30 is at the feeding position, the material in the containing cavity 11 can enter the transition cavity 31 through the flow port 32. When the sliding sleeve 30 is at the discharging position, the material in the transition cavity 31 can enter the filling channel 211. Specifically, in the embodiment, the containing cavity 11 of the material cylinder 10 is used to store the material. When the material is filled, first, the sliding sleeve 30 is at the feeding position, and the liquid level of the material in the containing cavity 11 is lower than that of the flow port 32, so that the material can enter the transition cavity 31 of the sliding sleeve 30 from the flow port 32. Then, the sliding sleeve 30 is made to slide upward along the filling piece 20, and the transition cavity 31 is moved upward relative to the top of the filling piece 20, so that the liquid level of the material in the transition cavity 31 reaches the filling piece 20, and the material in the transition cavity 31 can enter the filling channel 211 and then enter the filling container through the filling channel 211. The sliding sleeve 30 and the filling piece 20 which contact the material are arranged inside the material cylinder 10. The inside of the material cylinder 10 is a sterile environment, which can ensure the cleanliness and sterility of the material, and thus the product quality.

[0038] Further, referring to Figure 2 and Figure 3 , the filling device includes a plugging piece 40 which is fixedly connected to the sliding sleeve 30. When the sliding sleeve 30 is at the feeding position, the plugging piece 40 plugs the outlet 212 of the filling channel 211. Specifically, in the embodiment, the plugging piece 40 is fixedly connected to the sliding sleeve 30 and is located in the transition cavity 31 and coaxially arranged with the filling channel 211. When the sliding sleeve 30 slides along the filling piece 20, the plugging piece 40 slides in the filling channel 211. When the sliding sleeve 30 is at the feeding position, the plugging piece 40 plugs the outlet 212 of the filling channel 211. This arrangement makes the filling channel 211 be plugged when the filling is not performed, which can reduce the risk of foreign matter entering the filling channel 211, and thus further improve the cleanliness of the material and the product quality.

[0039] Furthermore, the flow opening 32 is square, and the bottom wall of the flow opening 32 is horizontally arranged. Specifically, in this embodiment, the bottom wall of the flow opening 32 is horizontally arranged. This arrangement allows the material in the accommodating chamber 11 to easily enter the transition chamber 31, and also makes the liquid level of the material in the transition chamber 31 horizontal. The total amount of material contained in the transition chamber 31 can be obtained by the height of the bottom wall of the flow opening 32 of the transition chamber 31, and the filling amount of the material of this filling can be controlled by controlling the rising height of the sliding sleeve 30, thereby improving the convenience and flexibility of filling.

[0040] Specifically, in this embodiment, Figure 4 As shown, when the bottom wall of the transition chamber 31 is flush with the top of the filling member 20, the filling volume of the filling device is maximum.

[0041] Furthermore, a plurality of flow openings 32 are provided, and the plurality of flow openings 32 are spaced apart on the side wall of the sliding sleeve 30 around the axis of the sliding sleeve 30. Specifically, in this embodiment, the plurality of flow openings 32 are spaced apart on the side wall of the sliding sleeve 30 around the axis of the sliding sleeve 30, so that the material can enter the transition chamber 31 through the plurality of flow openings 32 simultaneously, thereby increasing the material feeding speed and ensuring the filling efficiency.

[0042] Furthermore, the filling device further includes a driving member 50, which is disposed at the top of the material cylinder 10 and is in transmission connection with the sliding sleeve 30. The driving member 50 is used to drive the sliding sleeve 30 to slide relative to the filling member 20. Specifically, in this embodiment, the driving member 50 is disposed at the top of the material cylinder 10, and the driving member 50 drives the sliding sleeve 30 to slide relative to the filling member 20, thereby ensuring normal filling.

[0043] Furthermore, the driving member 50 is a pneumatic cylinder. Specifically, in this embodiment, the sliding sleeve 30 is further provided with a connecting rod 33. The connecting rod 33 is disposed at the end of the sliding sleeve 30 away from the filling member 20. The connecting rod 33 and the blocking member 40 are coaxially arranged. The connecting rod 33 is fixedly connected to the telescopic rod of the pneumatic cylinder. When the cylinder is extended or retracted, the connecting rod 33 can drive the sliding sleeve 30 to slide along the filling member 20, thereby ensuring normal filling.

[0044] Optionally, in other embodiments, the driving member 50 can be a motor, a screw rod is provided at the output end of the motor, a screw rod nut is threadedly connected to the screw rod, the screw rod nut and the connecting rod 33 are fixedly connected, and the rotation of the motor can drive the screw rod nut to move along the axis direction of the screw rod, thereby driving the sliding sleeve 30 to slide along the filling member 20.
