[0026] Referring to the accompanying drawings, the utility model provides a filling device, including a filling mechanism 100, a base 200 and a container support assembly 300. The filling mechanism 100 is installed on the base 200, and the filling mechanism is provided with a valve seat 1 and a filling seat 2. The valve seat 1 in the filling mechanism 100 is fixedly installed on the base 200, and a material discharge channel 11 is provided inside the valve seat 1. The lower end of the material discharge channel 11 is provided with a discharge port 110 corresponding to a first container can (in this embodiment, a can 401). The filling seat 2 is surrounded by the valve seat 1, and a first sealing joint annular structure 21 is provided at its lower end to cooperate with the upper end of the can 401. The sealing joint annular structure 21 can be a sealing ring installed at a corresponding position. The base 200 is a base with adjustable height, the container support assembly 300 is a support assembly that can be raised and lowered, and the filling seat 2 is a filling seat that can be raised and lowered; the filling mechanism is also provided with a discharge nozzle 3 corresponding to the second container bottle 402, the discharge nozzle 3 is detachably connected to the lower end of the valve seat 1, and is connected to the discharge channel 11, and the discharge nozzle 3 is provided with a second sealing engagement annular structure 31 that cooperates with the upper end of the second container bottle 402, and the sealing engagement annular structure 31 can be a sealing ring installed at a corresponding position. The second container bottle 402 is a narrow-mouthed bottle, the height of the second container bottle 402 is higher than that of the can 401, and the diameter of the bottle mouth 4021 is smaller than the diameter of the upper end of the can 401.

[0027] like Figure 1 As shown, when filling cans, the first sealing engagement annular structure 21 of the filling seat 2 is used to seal and engage with the can 401, and the can is discharged through the discharge port 110. For filling the cans 401, when the cans are in and out, the filling seat 2 is in a high position, and when filling, the filling seat 2 is lowered to a low position, and the lowering limit of the filling seat 2 exceeds the discharge port 110 but is higher than the lower end of the discharge nozzle 3.

[0028] As shown in the figure, the filling seat 2 is arranged at the lower end of the lifting connection structure, and forms a lifting guide with the valve seat 1, and a sealing structure 22 is arranged between the filling seat 2 and the valve seat 1; the lifting connection structure includes a controlled component 23 connected and matched with the lifting control mechanism, and as the filling device moves, the filling seat 2 is lifted and lowered in sequence under the control of the lifting control mechanism. When the utility model is applied to a rotary filling machine, the filling device performs a circular motion, the lifting control mechanism can be a ring-shaped lifting control track 501 arranged in the filling machine, and the controlled component 23 can be a roller.

[0029] The lifting connection structure includes a lifting rod 24, the lower end of which is connected to a transverse connecting piece 25, the filling seat 2 is connected to the transverse connecting piece 25, the lifting rod 24 is connected to a connecting seat 26, the connecting seat 26 is provided with the controlled component 23, and a compression spring 27 is also provided on the lifting rod 24 so that the controlled component 23 and the lifting control mechanism can cooperate closely.

[0030] like Figure 1 , Figure 2 As shown, the height adjustment of the base 200 is combined with the lifting and lowering of the container support assembly 300. Figure 1 As shown, for the can 401, the base 200 and the container support assembly 300 are adjusted to a fixed height and no longer lifted. The filling seat 2 is lifted based on the height of the base 200 to enable the can to be sealed during filling and released from the sealed state to enter and exit. Figure 2 As shown, for the narrow-necked bottle 402, after the base 200 is adjusted to a fixed height, the height does not change, but the narrow-necked bottle is pressurized and sealed during filling and released from the pressurized seal to be able to enter and exit through the lifting and lowering of the container support assembly 300. When filling the narrow-necked bottle, the discharge nozzle 3 is used to directly act on the upper end of the narrow-necked bottle, and its second sealing engagement annular structure 31 is sealed and engaged with the narrow-necked bottle, and the narrow-necked bottle is directly discharged and filled through the discharge nozzle 3.

[0031] The discharge nozzle 3 is a separate part, including an internal thread connection port 33 at the upper end, a bottle mouth limit port 32 at the lower end, and an annular step portion located at the upper end of the bottle mouth limit port, the second sealing joint annular structure 31 constitutes the annular step portion, and the internal thread connection port 33 is threadedly connected to the lower end of the valve seat 1. When the filling device switches to filling cans 401 and narrow-mouth bottles 402, it only needs to replace the filling seat 2 with the container support assembly 300, and the disassembly and assembly of the discharge nozzle 3 can be realized.

[0032] The base is connected to a height adjustment mechanism, which may be a screw-nut mechanism. The screw is rotatably installed in the filling machine, and the base 200 is connected to the nut. The screw rotates, and the nut can be raised or lowered to adjust the height of the base accordingly.

[0033] The container support assembly includes a support seat 5, and the support seat 5 is connected to the lifting drive structure. The lifting drive structure includes a lifting sleeve 51 and a fixed cylinder rod 52. The fixed cylinder rod 52 is provided with an air inlet and outlet channel 57, and its upper end is an air inlet and outlet. The lifting sleeve 51 is used as a cylinder body, which is slidably connected with the fixed cylinder rod 52, and the lifting sleeve 51 is driven to rise by compressed gas. The lifting sleeve 51 is also connected to a descending control mechanism to drive the lifting sleeve 51 to descend. The descending control mechanism can be a cam, or a ring control track 50 provided in the filling machine. The lifting sleeve 51 is provided with a controlled component 513 matching the control track 50, such as a roller.

[0034] The fixed cylinder rod 52 is connected to the fixed structure 53 and forms an air cavity with the lifting sleeve 51 and the sliding structure 56 connected to the top of the lifting sleeve 51. The fixed structure 53 is in the form of a sleeve and is located at the lower end of the air cavity. The fixed structure 53 is provided with a buffer structure 54 of the lifting sleeve. The sliding structure 56 is in the form of a sleeve and is fixedly installed on the upper end of the inner wall of the lifting sleeve 51. The sliding structure 56 and the fixed cylinder rod 52, as well as the fixed structure 53 and the fixed cylinder rod 52 are all sealed.

[0035] The controlled component 513 and the supporting seat 5 are located on both sides of the lifting sleeve 51 , and the lifting sleeve 51 is provided with a lifting guide matching structure 55 , which cooperates with the lifting guide rail 502 to further stabilize the lifting of the lifting sleeve 51 and the supporting seat 5 .

[0036] The lifting of the filling seat 2 and the container supporting assembly may also adopt other structures, such as directly adopting a cylinder to drive the lifting, adopting a piston rod to drive the lifting, or adopting an electric drive to drive the lifting.

[0037] The filling mechanism is provided with a guide core rod 4, and the discharge port 110 is trumpet-shaped. The guide core rod 4 passes through the discharge channel 11, and its lower end corresponds to the discharge port 110; the filling mechanism is also provided with a guide core rod head 41 corresponding to the discharge nozzle 3, and a center hole 40 is provided in the guide core rod, and a step hole is provided at the lower end of the center hole 40, and an insertion head 411 is provided at the upper end of the guide core rod head 41, which is inserted into the step hole and detachably connected through the insertion head 411 (for example, the sealing ring is directly clamped in this embodiment), and the guide core rod head 41 is detachably installed at the lower end of the guide core rod 4. When switching to fill the cans 401 and the narrow-mouth bottles 402, only the guide core rod head 41 is disassembled. In this way, by using the internal thread interface connection installation of the discharge nozzle 3 and the plug-in connection installation of the guide core rod head 41, it can be realized that when switching to fill the can 401 and the narrow-mouth bottle 402, both can have a suitable flow channel shape. For the can, there can be a trumpet-shaped discharge port, and during filling, the liquid flows down along the bottle wall in an umbrella shape, with a good filling effect and fewer bubbles. For the narrow-mouth bottle, the discharge nozzle 3 can have a flow channel 34 that gradually shrinks toward the center, thereby adapting to the shape of the narrow-mouth bottle mouth and allowing the liquid to flow down along the bottle wall.

[0038] The guide rod head 41 is provided with a central hole 410 connected with the central hole in the guide rod 4. The filling mechanism is provided with a detachably mounted liquid level probe 6, which passes through the central hole 40 or through both central holes 40 and 410 depending on whether the guide rod head 41 is pressed.
