[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] The filling device for aerosol production involved in this utility model is mainly used in aerosol filling production. The main purpose of this utility model is to solve the problem of excess gas pollution generated during pressurization after filling.
[0028] Example 1
[0029] like Figures 1-6 As shown, a filling device for aerosol production includes an operating table 100, a filling assembly 200, a sealing assembly 300, and a pressurizing assembly 400. The top of the operating table 100 has an operating surface for filling. An inverted L-shaped frame 10 is provided on the upper side of the operating table and is fixedly connected to the edge of the operating table 100. Three mounting holes are sequentially provided on the inverted L-shaped frame 10, and the three mounting holes are along the length of the operating table. The filling assembly 200, the sealing assembly 300, and the pressurizing assembly 400 are sequentially installed in the three mounting holes. The filling device 400 also includes an excess gas recovery structure 500, which has a recovery hood 501 and a collection pipe 502 that is in negative pressure communication with the recovery hood. When the pressurizing assembly 400 completes pressurizing of the aerosol bottle containing the aerosol, the excess gas recovery structure 500 recovers and stores the gas containing the aerosol between the outer side of the bottle opening and the pressurizing assembly 400.
[0030] Specifically, the filling assembly 200, sealing assembly 300, and pressurizing assembly 400 each include a telescopic structure 20. The telescopic structure 20 is fixedly mounted on the upper side of the inverted L-shaped frame 10, and its telescopic portion extends to the lower part of the inverted L-shaped frame 10. Specifically, the lower end of the telescopic portion of the telescopic structure in the filling assembly 200 is provided with a filling head 201; the lower end of the telescopic portion of the telescopic structure in the sealing assembly 300 is provided with a sealing pressure head 301; and the lower end of the telescopic portion of the telescopic structure in the pressurizing assembly 400 is provided with a pressure head 401. In this embodiment, the telescopic structure 20 is a hydraulic cylinder, pneumatic cylinder, or electric cylinder. The piston rod of the hydraulic cylinder, pneumatic cylinder, or electric cylinder is the telescopic portion.
[0031] It should be noted that the filling head 201, the sealing head 301 and the pressurizing head 401 are all cylindrical, and a bottle mouth accommodating cavity 30 in the shape of an inverted cone is formed on the lower end of the cylinder along the axis of the cylinder, and a connecting sleeve is formed on the upper end for connecting with the telescopic structure.
[0032] As for the filling assembly, a filling nozzle 2011 is arranged in the center of the accommodating cavity, and the filling nozzle 2011 is connected with the raw material supply device through a connecting pipe 2012. The lower end of the filling head 201 is in the shape of an inverted cone, so that if there is a small positional deviation between the aerosol bottle below the filling assembly 200 and the filling nozzle 201, the bottle mouth accommodating cavity 30 in the shape of an inverted cone can still fine-tune the position of the aerosol bottle as the filling head 201 descends, so as to ensure that the filling nozzle 2011 is accurately inserted into the aerosol bottle mouth.
[0033] As for the sealing assembly, a protruding circular bottle mouth pressing block 3011 is formed in the middle of the accommodating cavity 30 in the shape of an inverted cone, so that if there is a small positional deviation between the aerosol bottle below the sealing assembly 300 and the sealing head 301, the bottle mouth accommodating cavity 30 in the shape of an inverted cone can still fine-tune the position of the aerosol bottle as the sealing head 301 descends, so as to ensure that the bottle mouth pressing block 3011 accurately presses the bottle mouth.
[0034] As for the pressurizing assembly, a rubber layer (not shown in the figure) is arranged on the inner wall of the accommodating cavity 30 in the shape of an inverted cone. The rubber layer is adhered to the inner wall of the accommodating cavity 30 in the shape of an inverted cone by glue. The top of the accommodating cavity 30 in the shape of an inverted cone is provided with an air inlet pipe 4011. The part of the air inlet pipe 4011 outside the accommodating cavity is in communication with the pressurizing device, and the part inside the accommodating cavity is in communication with the accommodating cavity 30 in the shape of an inverted cone. A needle 4012 is connected to one end of the air inlet pipe 4011 inside the accommodating cavity 30 in the shape of an inverted cone. A plurality of air holes are formed at the connection between the air inlet pipe 4011 and the needle 4012, so as to ensure that the gas in the air inlet pipe 4011 can enter the accommodating cavity 30 in the shape of an inverted cone. When pressurizing, the edge of the bottle mouth abuts against the rubber layer, so as to form a sealed space between the bottle mouth and the accommodating cavity. The needle 4012 contacts the valve core on the cover of the aerosol bottle and presses the valve core into the bottle, so as to make the valve core in an open state. At this time, the external pressurizing device injects high-pressure gas into the sealed space between the accommodating cavity and the bottle mouth and into the bottle to complete the pressurizing.
[0035] In order to recycle the excess gas after pressurizing, the recycling cover 501 is arranged in the shape of an umbrella. The top of the recycling cover 501 is provided with a fixing cylinder, and the recycling cover 501 is fixed on the telescopic part of the telescopic structure 20 in the pressurizing assembly by means of the fixing cylinder, and the pressurizing head 401 is located inside the recycling cover 501 or directly below the recycling cover.
[0036] In order to create a negative pressure inside the recovery hood 401, a negative pressure interface 502 is provided on the outer side of the hood 401 near the top. The negative pressure interface 502 is connected to the inner side of the hood and is connected to the negative pressure fan and the gas recovery storage pipe through a connecting pipe. The negative pressure fan creates a negative pressure inside the recovery hood 501 to recover the gas containing aerosol between the outside of the bottle opening and the pressurization component.
[0037] Furthermore, the lower diameter of the recovery hood 501 is larger than that of the larger diameter of the pressurizing head 401 and the aerosol bottle, so that after pressurization, the gas containing the aerosol between the outer side of the bottle opening and the pressurizing component is within the range of the recovery hood 501.
[0038] Example 2
[0039] like Figures 1-5 as well as Figure 7 As shown, the difference from Embodiment 1 is that the recovery hood 501 in this embodiment further includes a cylindrical surrounding portion 503, which is fixedly connected to the lower end of the recovery hood 501. When the pressurizing assembly 400 is not in operation, the lower end of the surrounding portion 503 is higher than the upper end of the aerosol bottle to be pressurized on the operating table, to prevent the top of the aerosol bottle from colliding with the surrounding portion 502 during the process of the aerosol bottle moving from below the sealing assembly into the pressurizing assembly. The surrounding portion and the hood together reduce the possibility of gas escape, thereby maximizing gas recovery.
[0040] Finally, it should be noted that the recovery hood and surrounding part in Embodiments 1 and 2 can be made of transparent material, which makes it easy to observe the pressurization operation and gas recovery operation inside the recovery hood.
[0041] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
