During the filling process of the aerosol can, the staff only needs to load and unload once, which greatly reduces the staff's work intensity and improves the filling efficiency.

[0004] The above equipment separates the pressurizing and filling equipment, which increases the overall floor space and space of the above equipment, makes the pressurizing and filling operations not performed in step, and affects the stability and efficiency of the pressurizing and filling process. Utility Model Content

[0005] The utility model aims to provide aerosol can booster cylinder metering cylinder combined filling equipment to solve the technical problems that the existing booster and filling equipment are separated, which increases the overall equipment floor space and space, and cannot be operated simultaneously, affecting the stability and efficiency of the booster filling process.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The aerosol can booster cylinder and metering cylinder combined filling equipment comprises an electric push rod, a mounting plate is fixedly installed on the lower surface of the piston rod of the electric push rod, a metering cylinder and a booster cylinder are fixedly installed on the lower surface of the mounting plate, and a first pushing disk and a second pushing disk are fixedly installed on the outer surfaces of the piston rods of the metering cylinder and the booster cylinder.

[0008] A booster filling combination mechanism is fixedly installed on the lower surfaces of the metering cylinder and the booster cylinder, and the first pushing disk and the second pushing disk are sealed and slidable inside the booster filling combination mechanism.

[0009] As a preferred embodiment of the utility model, the pressurized filling combination mechanism includes a liquid injection cylinder and an air injection cylinder, which are respectively fixedly mounted on the lower surfaces of the metering cylinder and the boosting cylinder, and the second pushing disk and the first pushing disk are respectively sealed and slidable inside the liquid injection cylinder and the air injection cylinder.

[0010] As a further solution of the utility model, an injection tube is fixedly installed on the lower surface of the gas injection cylinder, a first solenoid valve is fixedly installed on the lower surface of the liquid injection cylinder, a docking tube is fixedly installed on the lower surface of the first solenoid valve, and the docking tube penetrates into the injection tube.

[0011] As a further solution of the utility model, the butt joint pipe located in the injection pipe can allow compressed air and refrigerant to be injected into the aerosol can together.

[0012] As a further preferred embodiment of the present invention, both the liquid injection cylinder and the gas injection cylinder are made of transparent material, and both have measuring scale lines on their outer surfaces.

[0013] As a preferred solution of the utility model, a second solenoid valve is installed on the outer surface of the liquid injection cylinder, and a liquid inlet pipe is fixedly installed at one end of the second solenoid valve. The liquid inlet pipe can extend to the refrigerant storage tank that needs to be filled in the aerosol can.

[0014] Compared with the prior art, the beneficial effects of the aerosol can booster cylinder metering cylinder combined filling device of the utility model are as follows: when in use, the booster filling combination mechanism at the lower end of the metering cylinder and the booster cylinder is pushed and sealed on the upper surface of the aerosol can by starting the electric push rod, and the booster cylinder is started to push the first pushing disk on the lower surface of the piston rod to push in the booster filling combination mechanism, so that the booster cylinder injects compressed air or other gas (such as nitrogen) into the aerosol can. This step is performed before filling the liquid material to provide the necessary pressure, and then the metering cylinder can be started again to drive the second pushing disk on the lower surface of the piston rod to lift up in the booster filling combination mechanism, so that the refrigerant to be filled can be introduced into the booster filling combination mechanism, and the metering cylinder can accurately control the amount of refrigerant introduced each time according to the lifting distance during the lifting process, and then the metering cylinder can push the second pushing disk again to inject the refrigerant from the booster filling combination mechanism into the pressurized aerosol can. At this time, the gas pressure in the tank is conducive to the rapid filling and uniform distribution of the refrigerant. After the refrigerant is filled, the sealing equipment can seal the aerosol can. Usually, a special sealing equipment is used to install the valve and nozzle on the can mouth to ensure that the can is well sealed and will not leak, thereby completing the pressurization and filling operations of the aerosol can. At the same time, the metering cylinder and the boosting cylinder are merged into the boosting and filling combination mechanism, so that the pressurization and filling operations can be carried out successively, and the aerosol can does not need to be moved again during the process, saving time and improving production efficiency. Pressurization and filling can be more closely integrated, reducing waiting and adjustment time, and merging them also reduces the footprint of the equipment, because there is no longer a need for separate space for the metering cylinder and the boosting cylinder, and the operator can complete the pressurization and filling operations at the same location, simplifying the operating process and the movement of personnel, and improving operating efficiency. Integrating the two functions into one device reduces the number of connecting components such as pipes and valves, reduces the complexity of the system and the potential risk of leakage, and can also make it easier for staff to inspect and repair it.

[0024] The boosting and filling assembly mechanism 3 is fixedly mounted on the lower surfaces of the metering cylinder 2 and the boosting cylinder 201, and the first pushing disk 202 and the second pushing disk 203 are sealed and slidable inside the boosting and filling assembly mechanism 3.

[0025] When the embodiment of the utility model is used, the electric push rod 1 can be started to push the metering cylinder 2 and the boost filling combination mechanism 3 at the lower end of the boost cylinder 201 to seal and press against the upper surface of the aerosol can. Then, the boost cylinder 201 can be started to push the first pushing plate 202 on the lower surface of the piston rod to push inside the boost filling combination mechanism 3, so that the boost cylinder 201 can inject compressed air or other gases (such as nitrogen) into the aerosol can. This step is performed before filling the liquid material to provide the necessary pressure.

[0026] Starting the metering cylinder 2 drives the second pushing plate 203 on the lower surface of the piston rod to lift up in the pressurized filling assembly mechanism 3, so that the refrigerant to be filled can be introduced into the pressurized filling assembly mechanism 3, and the metering cylinder 2 can accurately control the amount of refrigerant introduced each time according to the lifting distance during the lifting process, and then the metering cylinder 2 can push the second pushing plate 203 again to inject the refrigerant from the pressurized filling assembly mechanism 3 into the pressurized aerosol can. At this time, the gas pressure in the can is conducive to the rapid filling and uniform distribution of the refrigerant. After the refrigerant filling is completed, the sealing device can be used to seal the aerosol can. Usually, a special sealing device is used to install the valve and nozzle on the can mouth to ensure that the can is well sealed and will not leak, thereby completing the pressurization and filling operations of the aerosol can, and at the same time The metering cylinder 2 and the boosting cylinder 201 are merged into the boosting and filling combination mechanism 3, so that the boosting and filling operations can be carried out successively, and the aerosol can does not need to be moved again during the process, which saves time and improves production efficiency. The boosting and filling can be more closely integrated, reducing waiting and adjustment time. The merger also reduces the footprint of the equipment, because there is no need to place the metering cylinder 2 and the boosting cylinder 201 separately, and the operator can complete the boosting and filling operations at the same position, which simplifies the operating process and the movement of personnel, improves operating efficiency, and integrates the two functions into one device, reduces the number of connecting components such as pipes and valves, reduces the complexity of the system and the potential risk of leakage, and can also make it easier for staff to inspect and repair it.

[0027] See also Figure 2-Figure 3 As shown, the boost filling combination mechanism 3 includes a liquid injection cylinder 303 and a gas injection cylinder 301, which are respectively fixedly mounted on the lower surfaces of the metering cylinder 2 and the boost cylinder 201, and the second pushing disk 203 and the first pushing disk 202 are respectively sealed and slidable inside the liquid injection cylinder 303 and the gas injection cylinder 301.

[0029] The butt joint 307 located in the injection pipe 302 allows compressed air and refrigerant to be injected into the aerosol can together.

[0030] The liquid injection cylinder 303 and the gas injection cylinder 301 are both made of transparent material, and the outer surfaces thereof are both provided with measuring scale lines.

[0031] The outer surface of the liquid injection cylinder 303 is connected to a second solenoid valve 304 , and a liquid inlet pipe 305 is fixedly installed at one end of the second solenoid valve 304 . The liquid inlet pipe 305 can extend to the refrigerant storage tank that needs to be filled in the aerosol can.

[0032] When in use, the electric push rod 1 can be started to push the metering cylinder 2 and the injection tube 302 at the lower end of the booster cylinder 201 to seal and press against the upper surface of the aerosol can. Then the booster cylinder 201 can be started to push the first pushing plate 202 on the lower surface of the piston rod to slide in the gas injection cylinder 301, so that the booster cylinder 201 can inject compressed air or other gases (such as nitrogen) into the aerosol can. This step is performed before filling the liquid material to provide the necessary pressure. Then the metering cylinder 2 can be started again and the second solenoid valve 304 can be opened to drive the second pushing plate 203 on the lower surface of the piston rod to lift in the liquid injection cylinder 303, so that the refrigerant to be filled can be drawn into the liquid injection cylinder 303 through the liquid inlet pipe 305. During the lifting process, the metering cylinder 2 can accurately control the amount of refrigerant introduced each time according to the lifting distance, and then it can be used for metering. The measuring cylinder 2 closes the second solenoid valve 304 and opens the first solenoid valve 306 again, so that the measuring cylinder 2 pushes the second pushing disk 203 again to push the refrigerant from the liquid injection cylinder 303 into the docking pipe 307 through the first solenoid valve 306, and the docking pipe 307 runs through the injection pipe 302, so that the refrigerant can be injected into the pressurized aerosol can. After the refrigerant filling is completed, the sealing device can be used to seal the aerosol can. Usually, a special sealing device is used to install the valve and nozzle on the can mouth to ensure that the can is well sealed and will not leak, thereby completing the pressurization and filling operations of the aerosol can, and then the pressurization and filling operations can be carried out successively, and the aerosol can does not need to be moved again during the process, which saves time and improves production efficiency. Pressurization and filling can be more closely integrated, reducing waiting and adjustment time.

[0033] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when in use, the electric push rod 1 can be started to push the metering cylinder 2 and the injection tube 302 at the lower end of the booster cylinder 201 to seal and press against the upper surface of the aerosol can, and then the booster cylinder 201 can be started to push the first pushing plate 202 on the lower surface of the piston rod to slide in the gas injection cylinder 301, so that the booster cylinder 201 can inject compressed air or other gases (such as nitrogen) into the aerosol can. This step is performed before filling the liquid material to provide the necessary pressure, and then the metering cylinder 2 can be started again and the second solenoid valve 304 can be opened to drive the second pushing plate 203 on the lower surface of the piston rod to lift up in the liquid injection cylinder 303, so that the refrigerant to be filled can be drawn in through the liquid inlet pipe 305. The metering cylinder 2 can accurately control the amount of refrigerant introduced each time according to the lifting distance during the lifting process, and then the metering cylinder 2 can be supplied and the second solenoid valve 304 can be closed again and the first solenoid valve 306 can be opened, so that the metering cylinder 2 can push the second pushing disk 203 again to push the refrigerant from the liquid injection cylinder 303 into the docking pipe 307 through the first solenoid valve 306, and the docking pipe 307 runs through the injection pipe 302, so that the refrigerant can be injected into the pressurized aerosol can. After the refrigerant filling is completed, the sealing device can be used to seal the aerosol can. Usually, a special sealing device is used to install the valve and nozzle on the can mouth to ensure that the can is well sealed and will not leak, thereby completing the pressurization and filling operation of the aerosol can.

[0034] The embodiment of the utility model enables the pressurizing and filling operations to be carried out successively, and the aerosol can does not need to be moved again during the process, which saves time and improves production efficiency. The pressurizing and filling can be more closely integrated, reducing waiting and adjustment time, and combining them also reduces the footprint of the equipment. There is no longer a need for separate space for the metering cylinder 2 and the pressurizing cylinder 201, and the operator can complete the pressurizing and filling operations at the same position, simplifying the operating process and the movement of personnel, improving operating efficiency, and integrating functions, reducing the number of connecting components such as pipes and valves, reducing system complexity and potential leakage risks, and making it easier for staff to perform maintenance.
