Description

Technical Field

[0001] This application relates to the field of aerosol production technology, and in particular to a valve positioning mechanism for aerosol production. Background Technology

[0002] Aerosol production has a strong technological background, among which valves are the core components that ensure the sealing and spraying function of aerosols. With the advent of automated packaging equipment, valves can be automatically installed on aerosols, and then the valves are sealed to the aerosols using a sealing machine.

[0003] In existing technology, the valve sealing process for aerosols typically involves first placing the valve on top of the aerosol via a valve feeder, then conveying the aerosol and valve together to a positioning device. The positioning device then secures the aerosol bottle. Next, the valve and aerosol can are sealed using a valve sealing device, and finally, the valve is inflated by a valve inflation device. See also the utility model patent with publication number CN210103425U, entitled "A Sealing and Inflating Device for an Aerosol Filling Production Line."

[0004] Regarding the aforementioned technologies, in actual use, due to the vibration generated by the transmission components during transmission, the valve will inevitably deviate to a certain extent during the docking process with the aerosol, which will adversely affect the sealing of the subsequent aerosol can and valve and the aerosol filling. Summary of the Invention

[0005] In order to reduce the occurrence of valve misalignment during the sealing and inflation process of aerosols, this application provides a valve positioning mechanism for aerosol production.

[0006] The valve positioning mechanism for aerosol production provided in this application adopts the following technical solution: A valve positioning mechanism for aerosol production includes a frame, a turntable assembly, a positioning assembly, and a delivery pipeline. The turntable assembly includes a first turntable, a second turntable, and a plurality of rotating shafts. The plurality of rotating shafts are disposed on the first turntable or the second turntable, and the rotating shafts are driven by a drive motor mounted on the frame. The first turntable is connected to the second turntable through a conveying pipeline. The first turntable has a plurality of fixed abutment grooves distributed along the circumference of the first turntable. The second turntable has a plurality of fixed abutment grooves distributed along the circumference of the second turntable. The positioning component includes a pressing transmission rod, a positioning gripper, a transmission link, and a cylinder. The positioning component is disposed on a first turntable. The pressing transmission rod is throttledly connected to the output port of the cylinder. A plurality of positioning grippers are provided, and the plurality of positioning grippers are respectively configured as a first gripper and a second gripper. The first gripper and the second gripper are arranged opposite to each other, and both the first gripper and the second gripper are rotatably connected to the frame. A plurality of transmission links are provided, and the plurality of transmission links are respectively configured as a first transmission link and a second transmission link. The first transmission link and the second transmission link are respectively located on both sides of the pressing transmission rod. One end of the first transmission link is rotatably connected to the pressing transmission rod, and the other end of the first transmission link is rotatably connected to the first gripper. One end of the second transmission link is rotatably connected to the pressing transmission rod, and the other end of the second transmission link is rotatably connected to the second gripper. The delivery pipeline is provided with a valve abutment wall, which is located between the delivery pipeline and the first turntable and the second turntable. The valve abutment wall is located on the inner wall of the delivery pipeline, and there are protrusions on both sides of the valve abutment wall facing the inside of the delivery pipeline. After the valve is positioned by the positioning component, it will move and abut against the valve abutment wall as the aerosol can moves.

[0007] By adopting the above technical solution, the valve placed on top of the aerosol can can be positioned by the positioning component, so that the valve can be placed in the expected sealing position. The aerosol can with the valve in place is transported from the first turntable to the second turntable through the delivery pipeline. During the transportation process, the valve will abut against the valve abutment wall of the delivery pipeline, so that the valve will not deviate from the expected sealing position during the transportation process. After being transported to the second turntable, the aerosol can is rotated by the second turntable to the subsequent sealing equipment and inflation equipment.

[0008] Optionally, the conveying pipeline is arranged around the first turntable and the second turntable.

[0009] By adopting the above technical solution, the aerosol can can be driven by the second turntable as it passes through the first and second turntables, thereby achieving the effect of automated production.

[0010] Optionally, the gripping portion of the positioning gripper is arranged in an arc shape, and the gripping portion of the positioning gripper arranged in an arc shape is adapted to the valve.

[0011] By adopting the above technical solution, during the process of the cylinder pushing the pressure transmission rod up and down, the positioning gripper will be driven to rotate by the transmission link, so that the positioning gripper can grasp the cylinder. The arc shape design can also improve the gripping efficiency of the positioning gripper.

[0012] Optionally, the first turntable is provided with a valve discharge component, which is located at the top of the fixed abutment groove of the first turntable.

[0013] By adopting the above technical solution, the valve discharge component places the valve into the aerosol can that is pressed against the first turntable. The valve discharge component is connected to the fixed abutment groove, so that the valve will not be placed outside the aerosol can, thus improving the accuracy of valve placement.

[0014] Optionally, the second turntable is provided with a valve sealing component, which is disposed at the top of the fixed abutment groove of the second turntable.

[0015] By adopting the above technical solution, the valve and aerosol can are sealed by the sealing component. The valve, which is positioned and fixed to the valve abutment wall by the positioning component, will not shift, resulting in a good sealing effect of the valve sealing component.

[0016] Optionally, the second turntable is provided with a valve inflation component, which is located behind the valve sealing component along the circumferential direction of the second turntable.

[0017] By adopting the above technical solution, after the aerosol can is sealed with the valve, it will be driven by the second turntable to the valve inflation component. The valve inflation component will replenish nitrogen into the aerosol can, and the nitrogen will provide a stable pressure inside the can and be used to propel the contents out.

[0018] Optionally, there are two first turntables, which are arranged vertically along the length of the rotation axis, and the fixed abutment grooves of the two first turntables correspond one-to-one in the vertical direction.

[0019] By adopting the above technical solution, the aerosol can is more stable when driven by the first turntable, which not only improves the placement accuracy of the valve discharge component, but also improves the positioning efficiency of the positioning component.

[0020] Optionally, there are two second turntables, which are arranged vertically along the length of the rotating shaft, and the fixed abutment grooves of the two second turntables correspond one-to-one in the vertical direction.

[0021] By adopting the above technical solution, the aerosol can with the valve positioned can be more stable when it comes into contact with the second turntable. This not only improves the sealing efficiency of the valve sealing component, but also improves the inflation efficiency of the aerosol can by the subsequent valve inflation component.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The valve placed on top of the aerosol can is positioned by the positioning component, so that the valve can be placed in the expected sealing position. The aerosol can with the valve in place is transported from the first turntable to the second turntable through the delivery pipeline. During the transportation process, the valve will abut against the valve abutment wall of the delivery pipeline, so that the valve will not deviate from the expected sealing position during the transportation process. After being transported to the second turntable, the aerosol can is rotated by the second turntable to the subsequent sealing equipment and inflation equipment. 2. During the process of the cylinder pushing the pressure transmission rod up and down, the positioning gripper will be driven to rotate by the transmission linkage, so that the positioning gripper can grasp the cylinder. The arc shape design can also improve the gripping efficiency of the positioning gripper. 3. The aerosol can with the valve properly positioned can be more stable when it comes into contact with the second turntable, which can not only improve the sealing efficiency of the valve sealing component, but also improve the inflation efficiency of the aerosol can by the subsequent valve inflation component.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] Example 1: Embodiment 1 of this application discloses a valve positioning mechanism for aerosol production, referring to... Figure 1 It includes a turntable assembly 1, a positioning assembly 2, a conveying pipeline 3, and a frame, with the turntable assembly 1, the positioning assembly 2, and the conveying pipeline 3 all mounted on the frame.

[0033] Reference Figure 1 and Figure 2 The turntable assembly 1 includes a first turntable 11 and a second turntable 12. Two first turntables 11 are provided, coaxially fixedly connected by a rotating shaft 13 and arranged vertically along the length of the shaft 13. The stator of the drive motor 14 is fixedly mounted on the frame, and the mover of the drive motor 14 is coaxially fixed to the rotating shaft 13, so that the two first turntables 11 can be driven synchronously to rotate around the rotating shaft 13. The first turntable 11 has six fixed abutment grooves 101, distributed along the circumference of the first turntable 11, and the fixed abutment grooves 101 of the two first turntables 11 are aligned vertically. Furthermore, the first turntable 11 and the second turntable 12 are surrounded by the conveying pipeline 3. Through the cooperation between the inner wall of the fixed abutment groove 101 and the inner wall of the conveying pipeline 3, the aerosol can can be pressed tightly against the first turntable 11, allowing the aerosol can to be conveyed along with the rotation of the first turntable 11, and enabling the aerosol can to be carried to other subsequent processing steps. The simultaneous abutment of the two first turntables 11 also improves the stability of the aerosol can during rotation.

[0034] Reference Figure 3 The first turntable 11 is also equipped with a valve discharge component 15. The valve discharge component 15 is disposed on the top of any one of the fixed abutment grooves 101 in the first turntable 11, so that the valve discharge component 15 is in contact with the fixed abutment groove 101. When the aerosol can is driven by the first turntable 11 to the fixed abutment groove 101 corresponding to the valve discharge component 15, the valve discharge component 15 opens, placing the valve directly on the top of the aerosol can. Furthermore, the simultaneous contact of the two first turntables 11 can improve the stability of the aerosol can during rotation, achieving the effect of fixing the can body, thereby improving the accuracy of valve placement.

[0035] Reference Figure 3 and Figure 4 A positioning assembly 2 is provided next to the valve discharge component 15. The positioning assembly 2 includes a pressing transmission rod 21, a positioning gripper, a transmission connecting rod, and a cylinder 26. The pressing transmission rod 21 is driven to the output port of the cylinder 26.

[0036] The system has two positioning grippers, both with their central bends rotatably fitted onto the frame, allowing the rotation of one end of a gripper to drive the other end to rotate. The gripping portion at the bottom of the positioning gripper is arc-shaped and conforms to the shape of the valve, facilitating valve positioning using the two grippers.

[0037] Two positioning grippers are designated as a first gripper 22 and a second gripper 23, respectively, with the first gripper 22 and the second gripper 23 positioned opposite each other. The arc-shaped design also improves the gripping efficiency of the positioning grippers. The transmission linkage includes a first transmission link 24 and a second transmission link 25. One end of each of the first and second transmission links 24 and 25 is rotatably connected to a pressing transmission rod 21, and the other ends are rotatably connected to the tops of the first gripper 22 and the second gripper 23, respectively. When the pressing transmission rod 21 is displaced, the first and second transmission links 24 and 25 respectively drive the first gripper 22 and the second gripper 23 to move relative to each other, thereby achieving the gripping effect.

[0038] Specifically, whenever a valve aerosol can passes by, cylinder 26 pushes the pressure transmission rod 21, causing the first gripper 22 and the second gripper 23 to grasp and limit the valve. Then, as the pressure transmission rod 21 is pushed vertically, the valve can be placed in the predetermined sealing position, thereby achieving the positioning effect.

[0039] Reference Figure 5 Two second turntables 12 are provided, coaxially and fixedly connected by a rotating shaft 13, and arranged vertically along the length of the shaft 13. The drive motor 14 of the second turntable is fixedly mounted on the frame. Each second turntable 12 has six fixed abutment grooves 101, distributed along the circumference of the first turntable 11. The fixed abutment grooves 101 on both second turntables 12 are aligned vertically. Through the fixed abutment grooves 101, the aerosol can is able to abut against the second turntable 12, allowing the aerosol can to be conveyed along with the rotation of the second turntable 12, thus achieving automated conveying. The simultaneous abutment of the two first turntables 11 also improves the stability of the aerosol can during rotation.

[0040] Reference Figure 5The second turntable 12 is equipped with a valve sealing component 16, which is located on the top of the fixed abutment groove 101 of the second turntable 12. The aerosol can with the valve positioned by the positioning component 2 of the second turntable 12 will be transported to the second turntable 12 through the delivery pipeline 3. At this time, the aerosol can will be transferred to the valve sealing component 16 by abutting and cooperating with the second turntable 12. At this time, the valve sealing component 16 can seal the valve on the top of the aerosol can. The valve positioned by the positioning component 2 is not easy to deviate, so that the sealing effect of the valve sealing component 16 is good.

[0041] Reference Figure 5 The second turntable 12 is equipped with a valve inflation component 17, which is arranged behind the valve sealing component 16 along the circumferential direction of the second turntable 12. After the aerosol can is sealed with the valve, it will be driven to the valve inflation component 17 by the second turntable 12. Nitrogen gas is added to the aerosol can through the valve inflation component 17. The nitrogen gas provides a stable pressure in the can and is used to propel the contents out.

[0042] The implementation principle of the valve positioning mechanism for aerosol production in Embodiment 1 of this application is as follows: The aerosol can is first placed in the conveying pipeline 3. Through the conveying pipeline 3 and the abutment cooperation of the first turntable 11, the aerosol can is transported to the valve discharge component 15. At this time, the valve discharge component 15 places the valve on top of the aerosol can. When the aerosol can is transported to the positioning component 2, the cylinder 26 moves once and drives the abutment transmission rod 21 and the positioning gripper to position the cylinder 26, so that the valve can be placed in the expected sealing position. Then the aerosol can is driven by the conveying pipeline 3 to the second turntable 12, and through the abutment cooperation of the fixed abutment groove 101, the aerosol can is aligned with the valve sealing component 16. Due to the positioning by the positioning component 2, the valve sealing component 16 can accurately seal the valve and the aerosol can. After sealing, the aerosol can is inflated by the valve inflation component 17.

[0043] Example 2: Embodiment 2 of this application discloses a valve positioning mechanism for aerosol production, which, in addition to all the technical features of Embodiment 1, also includes the following technical features: Reference Figure 6 and Figure 7 The conveying pipeline 3 is provided with a valve abutment wall 31, which is located on the inner wall of the conveying pipeline 3. The valve abutment wall 31 has protrusions on both sides facing the inside of the conveying pipeline 3. After positioning, the valve will abut against the valve abutment wall as the aerosol can moves, so that the valve will not deviate from the expected sealing position during the conveying process, thus protecting the positioning effect of the positioning component 2.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
