[0036] Reference Figures 1-4 The utility model provides an aerosol propellant filling control device, which includes: a door-type frame 1, a tank stabilization control component, and a quantitative delivery component.

[0037] The tank body stabilization component is installed on the inner top of the door-type frame 1, and is used to stabilize the tank body 16 through the tank body stabilization component during the canning process to ensure that the tank body will not tilt / tip over during the canning process, and will not cause the aerosol propellant to spill. The quantitative delivery component is installed on the top of the door-type frame 1, and the discharge end of the quantitative delivery component is located inside the tank body stabilization component. The quantitative delivery component is used to quantitatively deliver the aerosol propellant into the tank body 16.

[0038] The tank stabilization assembly includes: an arc-shaped outer block 13, a telescopic member 14, and an annular limiting member 15. The top of the arc-shaped outer block 13 is fixedly connected to the inner top of the door-shaped frame 1, the top of the telescopic member 14 is fixedly connected to the inner top of the door-shaped frame 1, and the telescopic member 14 is located on the inner side of the arc-shaped outer block 13. The top of the annular limiting member 15 is fixedly installed on the bottom telescopic end of the telescopic member 14.

[0039] The telescopic member 14 pushes the annular limiting member 15 downward to move downward. The annular limiting member 15 can be sleeved on the bottle mouth of the can body and squeeze the can body 16 downward to keep the can body 16 stable. The arc-shaped outer stop 13 limits the up and down movement of the annular limiting member 15.

[0040] In one embodiment, a mounting plate 2 is fixedly connected to the outer side of the bottom of the portal frame 1, and a fixing hole 3 is opened on the top of the mounting plate 2 to facilitate the use of screws / bolts to fix the portal frame 1 to the conveyor belt, and the conveyor belt is used to realize the assembly line movement of the tank body 16.

[0041] In one embodiment, the quantitative delivery component includes: an airbag component 9 , a pressing component, a delivery pipe 7 , and a pump component 6 .

[0042] The airbag assembly 9 is arranged at the top of the portal frame 1, and the downward pressure assembly includes: a lifting member 4 fixedly installed with the portal frame 1, and the top telescopic end of the lifting member 4 is fixedly connected with a pressure plate member 5, and the pressure plate member 5 corresponds to the airbag assembly 9. The lifting member 4 controls the pressure plate member 5 to compress the airbag assembly 9 downward, so as to squeeze out the aerosol propellant inside the airbag assembly 9. A pump assembly 6 is installed on the delivery pipe 7, and the discharge end of the delivery pipe 7 is connected to the airbag assembly 9. A one-way valve 8 is installed on the delivery pipe 7 and between the airbag assembly 9 and the pump assembly 6. The one-way valve 8 prevents the backflow of the liquid. The pump assembly 6 is used to fill the inside of the airbag assembly 9 with liquid. A first discharge pipe 901 is provided at the bottom of the airbag assembly 9, and a second discharge pipe 902 is detachably and fixedly installed at the bottom end of the first discharge pipe 901. A back pressure assembly 17 is provided inside the second discharge pipe 902.

[0043] When in use, the pump assembly 6 works to transport liquid to the inside of the airbag assembly 9. Since the pressure of the liquid transported by the pump assembly 6 is lower than that of the back pressure assembly 17, the liquid will not be discharged from the second discharge pipe 902. During canning, the pump assembly 6 stops working and the down-pressure assembly presses the airbag assembly 9 downward. Due to the presence of the one-way valve 8, the liquid will not flow back into the pump assembly 6. As the pressure inside the airbag assembly 9 increases and exceeds the set pressure of the back pressure assembly 17, the liquid will be canned downward from the second discharge pipe 902 of the airbag assembly 9 into the tank body 16.

[0044] In one embodiment, the back pressure assembly 17 includes: a guide port 171 and an annular support 172 fixedly connected to the inside of the second discharge pipe 902, and the annular support 172 is located below the guide port 171, and a plug 174 corresponding to the bottom end of the guide port 171 is provided inside the second discharge pipe 902 and between the guide port 171 and the annular support 172, and a spring 173 is provided between the bottom of the plug 174 and the annular support 172.

[0045] The spring 173 pushes the plug 174 upward, and the top of the plug 174 cooperates with the bottom end of the guide port 171 to achieve sealing. When the internal pressure of the airbag assembly 9 is high, the plug 174 is pushed downward to overcome the elastic force of the spring 173, so that an overflow channel is formed between the plug 174 and the guide port 171.

[0046] In one embodiment, an upper pressure plate 10 is fixedly provided on the top of the airbag assembly 9, and the upper pressure plate 10 is located below the pressure plate member 5. A guide frame 11 is fixedly connected to the top of the door-shaped frame 1, and the guide frame 11 is slidably connected to the upper pressure plate 10. The guide frame 11 is used to guide the upper pressure plate 10, and the upper pressure plate 10 is used to bear the downward pressure of the downward pressure assembly to ensure that the top of the airbag assembly 9 is evenly stressed.

[0047] In one embodiment, a lower pad ring 12 is provided on the top of the portal frame 1 and below the airbag assembly 9 . The lower pad ring 12 is used to stably support the airbag assembly 9 .

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
