Abstract

This invention discloses an aerosol can cleaning device, relating to the field of aerosol can technology. It comprises a frame, a turntable, etc. The frame has loading and unloading stations and a gear ring. The turntable connects to multiple can-carrying trays distributed around its axis, transporting aerosol cans from the inlet to the outlet. A retainer is connected to the turntable, with gears meshing with the gear ring. The gears are floatingly connected to a pressure plate, which presses down on the aerosol can. When the turntable rotates, the gears drive the pressure plate to rotate on its own axis and around the turntable's axis, causing the aerosol can and the can-carrying tray to rotate. A limiting plate on the frame, with its surface distance from the turntable increasing along the direction of rotation, abuts against the limiting ring groove of the pressure plate, controlling the pressure plate to rise and release the can at the unloading station and press down at the loading station.

The device ensures thorough cleaning of the sidewalls by causing the aerosol cans to rotate while revolving around the turntable, avoiding impurity residue and improving the quality of heat-shrink film packaging.

Description

Technical Field

[0001] This invention relates to the field of aerosol can technology, and in particular to an aerosol can cleaning device. Background Technology

[0002] Heat shrink film packaging equipment in aerosol can production is a specialized device for packaging aerosol cans. It uses heat shrink film to wrap the aerosol cans and heats it to shrink and adhere it to the surface of the can, thus achieving sealing, protection, and packaging. Aerosol can cleaning equipment, as upstream equipment of the packaging equipment, cleans the sidewalls of the aerosol cans to remove impurities, ensuring that the sidewalls of the cans entering the packaging equipment are free of impurities, thereby guaranteeing the quality of the heat shrink film packaging. In existing technology, aerosol can cleaning equipment includes a conveying device and two brush rollers. The conveying device transports multiple aerosol cans, and the two brush rollers are located on both sides of the conveying device. The two brush rollers rotate and scrape the sidewalls of the aerosol cans on the conveying device to remove impurities. Finally, the conveying device transports the cleaned aerosol cans to the packaging equipment for heat shrink film packaging. Because the aerosol cans only move along a preset path on the conveying device, the brush rollers cannot completely cover the side walls of the aerosol cans when they rotate, resulting in some areas of the side walls of the aerosol cans not being thoroughly cleaned and easily leaving impurities, which in turn reduces the packaging quality of the heat shrink film. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an aerosol can cleaning device that can achieve comprehensive cleaning of the side walls of the aerosol can, which is beneficial to improving the packaging quality of heat shrink film.

[0004] According to an embodiment of the present invention, an aerosol can cleaning device includes a frame with a loading station, a unloading station, a gear ring, and a turntable; a brush device located between the loading station and the unloading station; multiple can-carrying trays rotatably connected to the turntable and circumferentially distributed around the axis of the turntable; a retainer connected to the turntable, on which multiple gears meshing with the gear ring are rotatably connected; and multiple pressure plates respectively disposed above the multiple can-carrying trays, the multiple pressure plates being floatingly connected to the multiple gears, and the turntable driving the... When the cage rotates, the multiple gears drive the multiple pressure plates to rotate. Each pressure plate rotates at least one revolution in the area corresponding to the brush device. The pressure plate can descend in the area between the loading station and the brush device to press the aerosol can onto the can carrier plate. While the aerosol can and the can carrier plate rotate around the axis of the turntable, the pressure plate drives the aerosol can and the can carrier plate to rotate. The brush device is used to clean the side wall of the aerosol can. The pressure plate can rise at the unloading station and detach from the aerosol can.

[0005] It has at least the following beneficial effects:

[0006] During the synchronous rotation of the turntable and cage, the pressure plate presses the aerosol cans onto the can-carrying tray. The aerosol cans on the tray then rotate around the turntable's axis under the clamping action of the tray and pressure plate, allowing them to move from the loading station to the unloading station. During this synchronous rotation, multiple gears mesh with the gear ring, causing them to rotate on their own axes. This rotation drives multiple pressure plates to rotate around the turntable's axis, which in turn causes the aerosol cans and the can-carrying tray to rotate around the turntable's axis. As the aerosol cans rotate both on their own axes and around the turntable's axis, a brush device scrapes the sidewalls of the aerosol cans, cleaning them. The pressure plate then rises and detaches from the aerosol can at the unloading station, allowing the worker to remove the cleaned aerosol can. This aerosol can cleaning equipment allows the aerosol can to rotate as it rotates around the axis of the turntable, enabling the brush device to thoroughly scrape and clean the side walls of the aerosol can. This prevents impurities from remaining on the side walls of the aerosol can due to incomplete cleaning, thereby improving the packaging quality of the heat shrink film.

[0007] According to an embodiment of the present invention, the aerosol can cleaning device further includes a limiting plate. The outer wall of the pressure plate is provided with a limiting annular groove. The limiting plate is disposed on the frame and located above the can-carrying tray. The limiting plate and the brush device are respectively disposed on both sides of the turntable. The insertion end of the limiting plate corresponds to the area between the brush device and the unloading station. The detachment end of the limiting plate corresponds to the area between the loading station and the brush device. The height difference between the upper surface of the limiting plate and the turntable gradually increases along the moving path of the can-carrying tray from the unloading station to the loading station. The limiting plate is used to extend into the limiting annular groove on the pressure plate. After the pressure plate detaches from the detachment end of the limiting plate, it presses the aerosol can onto the can-carrying tray. After the insertion end of the limiting plate extends into the limiting annular groove on the pressure plate, the pressure plate gradually rises and detaches from the aerosol can at the unloading station.

[0008] According to an embodiment of the aerosol can cleaning device of the present invention, a transition plate is further included. The transition plate is disposed above the turntable. The first end of the transition plate is connected to the disengagement end of the limiting plate. The transition plate is disposed in the area between the loading station and the brush device. The height between the upper surface of the transition plate and the turntable gradually decreases along the moving path of the can-carrying tray from the loading station to the brush device. The transition plate is used to extend into the limiting ring groove on the pressure plate. After the pressure plate disengages from the disengagement end of the limiting plate, the first end of the transition plate extends into the limiting ring groove on the pressure plate. When the pressure plate moves to the second end of the transition plate, the pressure plate presses the aerosol can onto the can-carrying tray.

[0009] The aerosol can cleaning device according to an embodiment of the present invention further includes a plurality of universal balls, all of which are disposed on the limiting plate and distributed along the extending direction of the limiting plate. The limiting plate abuts against the upper inner sidewall of the limiting ring groove through the universal balls.

[0010] According to an embodiment of the aerosol can cleaning device of the present invention, a can-dispensing wheel is further included. The can-dispensing wheel is coaxially arranged with and connected to the turntable. The can-dispensing wheel is disposed between the turntable and the retainer. The outer wall of the can-dispensing wheel is provided with a plurality of positioning grooves. The plurality of positioning grooves are respectively arranged corresponding to a plurality of can-carrying trays. The positioning grooves are used to accommodate aerosol cans. When the turntable drives the can-dispensing wheel to rotate, the positioning grooves rotate sequentially to the loading station, the unloading station, and then rotate back to the loading station and repeat cyclically.

[0011] The aerosol can cleaning equipment according to an embodiment of the present invention further includes a conveying device, which is used to deliver the aerosol can to be cleaned to the loading station and to remove the aerosol can from the unloading station.

[0012] According to an embodiment of the aerosol can cleaning device of the present invention, the can carrier tray is provided with a first anti-slip pad, the can carrier tray supports the aerosol can through the first anti-slip pad, and the pressure plate is provided with a second anti-slip pad, the pressure plate presses against the aerosol can through the second anti-slip pad.

[0013] According to an embodiment of the aerosol can cleaning device of the present invention, the brush device includes multiple brush rollers, the lower ends of the multiple brush rollers are rotatably connected to the frame, the multiple brush rollers are distributed along the edge of the turntable, and the multiple brush rollers are used to clean the side wall of the aerosol can.

[0014] According to an embodiment of the aerosol can cleaning device of the present invention, the brush device further includes a housing, a vacuum generating mechanism and a filter. The housing is disposed on the frame, and the opening of the housing faces the turntable. Partial structures of the plurality of brush rollers extend into the housing. The vacuum generating mechanism is connected to the housing through the filter. The vacuum generating mechanism is used to create a negative pressure in the housing, and the filter is used to filter impurities.

[0015] According to an embodiment of the aerosol can cleaning device of the present invention, the brush device further includes multiple levers parallel to the vertical direction. The multiple levers are all disposed inside the housing, and the multiple levers respectively abut against the brushes of the multiple brush rollers so that the impurities attached to the brushes of the brush rollers are brushed off.

[0039] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0040] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0041] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0042] refer to Figures 1 to 6 This invention discloses an aerosol can cleaning device, including a frame 600, a loading station 20, a unloading station 30, a gear ring 350, and a turntable 100; a brush device 400, mounted on the frame 600, located between the loading station 20 and the unloading station 30; multiple can-carrying trays 110, all rotatably connected to the turntable 100 and circumferentially distributed around the axis of the turntable 100, wherein when the turntable 100 rotates, the can-carrying trays 110 sequentially rotate to the loading station 20, the unloading station 30, and then rotate back to the loading station 20, repeating the cycle; a retainer 300, connected to the turntable 100, with multiple gears 310 rotatably connected to the retainer 300 and meshing with the gear ring 350; and multiple pressure plates 320, respectively located above the multiple can-carrying trays 110. The discs 320 are floatingly connected to multiple gears 310. When the turntable 100 drives the retainer 300 to rotate, the multiple pressure discs 320 rotate around the axis of the turntable 100. The multiple gears 310 drive the multiple pressure discs 320 to rotate on their own axis. The pressure discs 320 rotate at least once in the area corresponding to the brush device 400. The pressure discs 320 can descend in the area between the loading station 20 and the brush device 400 so that the pressure discs 320 press the aerosol can 10 onto the can-carrying disc 110. While the aerosol can 10 and the can-carrying disc 110 rotate around the axis of the turntable 100, the pressure discs 320 drive the aerosol can 10 and the can-carrying disc 110 to rotate on their own axis. The brush device 400 is used to clean the side wall of the aerosol can 10. The pressure discs 320 can rise at the unloading station 30 and detach from the aerosol can 10.

[0043] In one embodiment of the present invention, the brush device 400 can be a common arc-shaped brush plate, with the bristles of the arc-shaped brush plate facing the turntable 100. The bristles of the arc-shaped brush plate are used to scrape the side wall of the aerosol can 10. In this embodiment of the present invention, the axis of rotation of the turntable 100 is the axis of the turntable 100. (See reference) Figures 5 to 7The aerosol can cleaning device also includes a rotating shaft 120 and a first rotary drive (not shown in the figure). The first rotary drive is mounted on a frame 600. Both the upper and lower ends of the rotating shaft 120 are rotatably connected to the frame 600. The turntable 100 and the retainer 300 are both connected to the rotating shaft 120. The turntable 100, the retainer 300, and the rotating shaft 120 are all coaxially arranged, with the retainer 300 located above the turntable 100. The output end of the first rotary drive is connected to the lower end of the rotating shaft 120, enabling the first rotary drive to drive the rotating shaft 120 to rotate, thus causing the turntable 100 and the retainer 300 to rotate synchronously. Multiple gears 310 are rotatably connected to the retainer 300, and the multiple gears 310 are respectively arranged corresponding to multiple can-carrying trays 110, that is, the multiple gears 310 are also circumferentially distributed around the axis of the turntable 100 and the retainer 300.

[0044] In this embodiment of the invention, multiple pressure plates 320 are each connected to multiple gears 310 via multiple compression springs 340, so that the pressure plates 320 are floatingly connected to the gears 310, meaning that the pressure plates 320 can rise and fall relative to the gears 310. The multiple pressure plates 320 are respectively arranged corresponding to multiple tank trays 110, such that the multiple pressure plates 320 are also circumferentially distributed around the axis of the turntable 100 and the retainer 300. It should be noted that the number of tank trays 110, pressure plates 320, and gears 310 are all equal.

[0045] In this embodiment of the invention, the aerosol can cleaning device further includes bearings in the same number as the can-carrying trays 110. The turntable 100 has stepped mounting grooves in the same number as the can-carrying trays 110. Multiple bearings are respectively disposed within multiple stepped mounting grooves, and the outer rings of the multiple bearings are respectively connected to the inner walls of the multiple stepped mounting grooves. The lower surfaces of the multiple can-carrying trays 110 are each provided with mounting posts. The mounting posts on the lower surfaces of the multiple can-carrying trays 110 are respectively interference-fitted with the inner rings of the multiple bearings, thereby allowing the can-carrying trays 110 to be rotatably connected to the turntable 100. The upper surface of the can-carrying trays 110 is used to support the aerosol cans 10, and the upper surface of the can-carrying trays 110 is flush with the upper surface of the turntable 100.

[0046] In one embodiment of the present invention, the turntable 100 and the retainer 300 rotate intermittently. One of the can-carrying trays 110 on the turntable 100 rotates to the loading station 20 and then stops rotating. The worker then places the aerosol can 10 to be cleaned on the can-carrying tray 110 at the loading station 20, so that the can-carrying tray 110 at the loading station 20 can support the aerosol can 10. Then the turntable 100 continues to rotate, so that the next can-carrying tray 110 rotates to the loading station 20 and then stops rotating. The worker then places the next aerosol can 10 to be cleaned on the can-carrying tray 110 at the loading station 20, and so on. Further details are omitted here. During the rotation of turntable 100, the can-carrying tray 110 sequentially rotates to the loading station 20, then to the unloading station 30, and then back to the loading station 20, repeating this cycle. This allows the can-carrying tray 110 to rotate the aerosol cans 10 it supports around the axis of turntable 100, thereby moving the aerosol cans 10 it supports from the loading station 20 to the unloading station 30. Once the can-carrying tray 110 and the aerosol cans 10 on it have moved to the unloading station 30, the worker removes the cleaned aerosol cans 10 from the unloading station 30 and sends them to the heat shrink film packaging equipment for heat shrink film packaging.

[0047] During the rotation of turntable 100, refer to Figure 7 and Figure 8 The turntable 100 drives the cage 300 to rotate synchronously and intermittently, causing multiple gears 310, multiple compression springs 340, and multiple pressure plates 320 to rotate around the axis of the turntable 100. This causes the corresponding tank tray 110, pressure plate 320, and gears 310 to rotate sequentially to the loading station 20, the unloading station 30, and then back to the loading station 20, repeating this cycle. The frame 600 is equipped with a gear ring 350, and multiple gears 310 mesh with the gear ring 350. Therefore, while the cage 300 drives the multiple gears 310 to rotate around the axis of the turntable 100, the multiple gears 310 can also rotate on their own axes, allowing each gear 310 to drive multiple pressure plates 320 to rotate around the axis of the turntable 100 while rotating on their own axes. The area between the pressure plate 320 and the can-carrying tray 110 is used to accommodate the aerosol can 10. The compression spring 340 can push the pressure plate 320 downward, so that the pressure plate 320 can press the aerosol can 10 tightly onto the can-carrying tray 110. Therefore, during the synchronous rotation of the turntable 100 and the cage 300, the pressure plate 320 can press the aerosol can 10 and rotate with the aerosol can 10 around the axis of the turntable 100. Furthermore, the pressure plate 320 rotates on its own axis during the rotation around the axis of the turntable 100, thus driving the rotation of both the aerosol can 10 and the can-carrying tray 110. The friction between the can-carrying tray 110 and the aerosol can 10 allows the can-carrying tray 110 to rotate synchronously with the rotating aerosol can 10, ensuring that the aerosol can 10 can rotate smoothly during the rotation around the axis of the turntable 100.

[0048] refer to Figures 1 to 4 The aerosol can cleaning equipment also includes a limiting plate 610. The outer wall of the pressure plate 320 is provided with a limiting annular groove 321. The limiting plate 610 is mounted on the frame 600. The limiting plate 610 and the brush device 400 are respectively located on both sides of the turntable 100. The insertion end 611 of the limiting plate 610 corresponds to the area between the brush device 400 and the unloading station 30, and the disengagement end 612 of the limiting plate 610 corresponds to the area between the loading station 20 and the brush device 400. The upper surface of the limiting plate 610... The height difference between the platen 100 and the turntable 100 gradually increases along the moving path of the can-carrying plate 110 from the unloading station 30 to the loading station 20. The limiting plate 610 is used to extend into the limiting ring groove 321 on the pressure plate 320. After the pressure plate 320 is separated from the disengagement end 612 of the limiting plate 610, it presses the aerosol can 10 onto the can-carrying plate 110. After the insertion end 611 of the limiting plate 610 extends into the limiting ring groove 321 on the pressure plate 320, the pressure plate 320 gradually rises and separates from the aerosol can 10 at the unloading station 30.

[0049] As the height difference between the upper surface of the limiting plate 610 and the turntable 100 gradually increases along the moving path of the loading tray 110 from the unloading station 30 to the loading station 20, and the insertion end 611 of the limiting plate 610 corresponds to the area between the brush device 400 and the unloading station 30, and the detachment end 612 of the limiting plate 610 corresponds to the area between the loading station 20 and the brush device 400, when the pressure plate 320 moves to the area between the brush device 400 and the unloading station 30, the insertion end 611 of the limiting plate 610 can be inserted into the limiting ring groove 321 on the pressure plate 320. That is, when the pressure plate 320 is about to turn to the unloading station 30, the upper inner sidewall of the upper limiting ring groove 321 of the pressure plate 320 has already abutted against the upper surface of the limiting plate 610. As the pressure plate 320 rotates around the axis of the turntable 100, the limiting plate 610 causes the pressure plate 320 to gradually rise during this rotation. The compression spring 340 is compressed, so that when the pressure plate 320 moves to the unloading station 30, it has already released the aerosol can 10 at the unloading station 30, allowing the worker to easily remove the aerosol can 10. The pressure plate 320 continues to rotate around the axis of the turntable 100, with the upper inner wall of the upper limiting ring groove 321 of the pressure plate 320 abutting against the upper surface of the limiting plate 610, and the pressure plate 320 continues to rise.

[0050] refer to Figure 2 and Figure 4When the pressure plate 320 moves to the loading station 20, the upper inner sidewall of the upper limit ring groove 321 of the pressure plate 320 still abuts against the disengagement end 612 of the limit plate 610. At this time, the can-carrying tray 110 is already stationed at the loading station 20, and the distance between the pressure plate 320 and the can-carrying tray 110 at the loading station 20 is greater than the height of the aerosol can 10, so that the worker can smoothly place the aerosol can 10 between the can-carrying tray 110 and the pressure plate 320 at the loading station 20, ensuring that the can-carrying tray 110 at the loading station 20 can support the aerosol can 10. Next, the turntable 100 and the retainer 300 continue to rotate, and the pressure plate 320 moves to the area between the loading station 20 and the brush device 400. At this time, the pressure plate 320 disengages from the release end 612 of the limiting plate 610, and the compression spring 340 extends and pushes down the pressure plate 320, so that the pressure plate 320 presses the aerosol can 10 firmly onto the can carrier plate 110. As the turntable 100 and the retainer 300 continue to rotate, the corresponding pressure plate 320, aerosol can 10, and can carrier plate 110 enter the area of ​​the brush device 400, so that the brush device 400 can clean the aerosol can 10 pressed by the pressure plate 320. It should be noted that, according to the reference... Figure 1 and Figure 2 When the pressure plate 320 rotates to the loading station 20, the upper inner wall of the upper limit annular groove 321 of the pressure plate 320 still abuts against the upper surface of the limiting plate 610, thus avoiding interference with the placement of the aerosol can 10. After the turntable 100 and the retainer 300 rotate synchronously at a certain angle, the aerosol can 10 and the can-carrying tray 110 at the loading station 20 leave the loading station 20. At this time, the pressure plate 320 rotates around the axis of the turntable 100 at a certain angle and then disengages from the disengagement end 612 of the limiting plate 610. The pressure plate 320 can then press the aerosol can 10 firmly onto the can-carrying tray 110.

[0051] Understandably, after the worker places the aerosol can 10 to be cleaned onto the can-carrying tray 110 at the loading station 20, the pressure plate 320 at the loading station 20 is positioned above the aerosol can 10. Then, with the synchronous rotation of the turntable 100 and the retainer 300, the pressure plate 320 disengages from the disengagement end 612 of the limiting plate 610, and the compression spring 340 extends and pushes down on the pressure plate 320, pressing the aerosol can 10 firmly onto the can-carrying tray 110. During the synchronous rotation of the turntable 100 and the retainer 300, the aerosol can 10 on the can-carrying tray 110 rotates around the axis of the turntable 100 under the clamping action of the can-carrying tray 110 and the pressure plate 320, allowing the aerosol can 10 on the can-carrying tray 110 to move from the loading station 20 to the unloading station 30. During the synchronous rotation of the turntable 100 and the cage 300, since multiple gears 310 mesh with the gear ring 350, the multiple gears 310 can rotate on their own axis while rotating around the axis of the turntable 100. This allows the multiple gears 310 to drive multiple pressure plates 320 to rotate around the axis of the turntable 100 while rotating on their own axis. Consequently, the pressure plates 320 can drive the aerosol can 10 and the can carrier plate 110 to rotate on their own axis while rotating around the axis of the turntable 100. During the rotation of the aerosol can 10 on its own axis and rotation around the axis of the turntable 100, the pressure plates 320 drive the aerosol can 10 to rotate at least one revolution in the area corresponding to the brush device 400. The brush device 400 can scrape the side wall of the aerosol can 10 to achieve the purpose of cleaning the side wall of the aerosol can 10. After the aerosol can 10, pressure plate 320, and can carrier tray 110 leave the brush device 400, the insertion end 611 of the limiting plate 610 is inserted into the limiting ring groove 321 on the pressure plate 320. As the turntable 100 and the retainer 300 continue to rotate, the limiting plate 610 causes the pressure plate 320 to gradually rise during its rotation around the axis of the turntable 100. The compression spring 340 is compressed, so that when the pressure plate 320 moves to the unloading station 30, it has already released the aerosol can 10 at the unloading station 30, and the worker can then remove the cleaned aerosol can 10. This aerosol can cleaning equipment allows the aerosol can 10 to rotate during its rotation around the axis of the turntable 100, enabling the brush device 400 to thoroughly scrape and clean the side walls of the aerosol can 10, avoiding the residue of impurities on the side walls of the aerosol can 10 due to incomplete cleaning, thereby improving the packaging quality of the heat shrink film.

[0052] refer to Figure 13As another embodiment of the present invention, the aerosol can cleaning device further includes a transition plate 630, which is disposed above the turntable 100. The first end of the transition plate 630 is connected to the disengagement end 612 of the limiting plate 610. The transition plate 630 is disposed in the area between the loading station 20 and the brush device 400. The height between the upper surface of the transition plate 630 and the turntable 100 gradually decreases along the moving path of the can-carrying tray 110 from the loading station 20 to the brush device 400. The transition plate 630 is used to extend into the limiting ring groove 321 on the pressure plate 320. After the pressure plate 320 disengages from the disengagement end 612 of the limiting plate 610, the first end of the transition plate 630 extends into the limiting ring groove 321 on the pressure plate 320. When the pressure plate 320 moves to the second end of the transition plate 630, the pressure plate 320 presses the aerosol can 10 onto the can-carrying tray 110.

[0053] Understandably, when the pressure plate 320 moves to the loading station 20, the upper inner wall of the upper limit ring groove 321 of the pressure plate 320 still abuts against the disengagement end 612 of the limit plate 610. At this time, the distance from the pressure plate 320 to the can-carrying tray 110 at the loading station 20 is greater than the height of the aerosol can 10, so that the conveying device 500 can smoothly deliver the aerosol can 10 between the can-carrying tray 110 and the pressure plate 320 at the loading station 20, ensuring that the can-carrying tray 110 at the loading station 20 can support the aerosol can 10. Then the turntable 100 and the retainer 300 continue to rotate, and the pressure plate 320 moves to the area between the loading station 20 and the brush device 400. The pressure plate 320 disengages from the disengagement end 612 of the limit plate 610, and at this time the transition plate 630 extends into the limit ring groove 321 on the pressure plate 320. As the height between the upper surface of the transition plate 630 and the turntable 100 gradually decreases along the moving path of the can-carrying tray 110 from the loading station 20 to the brush device 400, the pressure plate 320 gradually descends as the turntable 100 and the retainer 300 continue to rotate and the pressure plate 320, aerosol can 10, and can-carrying tray 110 move toward the brush device 400. When the pressure plate 320 moves to the second end of the transition plate 630, it presses the aerosol can 10 onto the can-carrying tray 110. That is, before the pressure plate 320, aerosol can 10, and can-carrying tray 110 reach the brush device 400, the pressure plate 320 has already pressed the aerosol can 10 onto the can-carrying tray 110. As the turntable 100 and the retainer 300 continue to rotate, the pressure plate 320 disengages from the second end of the transition plate 630. The transition plate 630 allows the pressure plate 320 to descend slowly, so as to avoid the pressure plate 320 impacting the aerosol can 10, thereby preventing the aerosol can 10 from shaking during the pressing process, and ensuring that the pressure plate 320 can smoothly press the aerosol can 10 onto the can carrier plate 110.

[0054] In this embodiment of the invention, a first anti-slip pad is provided on the can-carrying tray 110, which supports the aerosol can 10. A second anti-slip pad is provided on the pressure plate 320, which presses against the aerosol can 10 through the second anti-slip pad. It is understood that the first anti-slip pad increases the friction between the can-carrying tray 110 and the aerosol can 10, preventing slippage. The second anti-slip pad further increases the friction between the pressure plate 320 and the aerosol can 10, preventing slippage and allowing the pressure plate 320 to smoothly drive the aerosol can 10 and the can-carrying tray 110 to rotate. The second anti-slip pad also reduces the impact of the pressure plate 320 on the aerosol can 10. The first and second anti-slip pads can be common rubber pads.

[0055] refer to Figure 11 In another embodiment of the present invention, the aerosol can cleaning device further includes a plurality of universal balls 620, all of which are disposed on the limiting plate 610. The universal balls 620 are distributed along the extending direction of the limiting plate 610, and the limiting plate 610 abuts against the upper inner wall of the limiting ring groove 321 through the universal balls 620. It can be understood that the upper surface of the limiting plate 610 abuts against the upper inner wall of the upper limiting ring groove 321 of the pressure plate 320 through the universal balls 620, so that while the upper inner wall of the upper limiting ring groove 321 of the pressure plate 320 is in contact with the limiting plate 610, the balls in the universal balls 620 can roll under the action of the upper inner wall of the limiting ring groove 321, thereby reducing the friction between the upper surface of the limiting plate 610 and the upper inner wall of the limiting ring groove 321. The universal ball 620 is a common mechanical part, which is usually composed of a ball and a ball seat, and will not be described further here. In another embodiment of the present invention, the limiting plate 610 is provided with a mounting hole, and a first magnet is disposed in the mounting hole. A second magnet is disposed on the pressure plate 320. The first magnet and the second magnet repel each other to reduce the frictional force between the upper surface of the limiting plate 610 and the side wall of the limiting ring groove 321. It can be understood that during the process of the pressure plate 320 rotating around the axis of the turntable 100 and the inner side wall of the upper limit ring groove 321 of the pressure plate 320 abutting against the limiting plate 610, the first magnet on the limiting plate 610 and the second magnet on the pressure plate 321 repel each other, thereby reducing the contact force between the upper surface of the limiting plate 610 and the inner side wall of the limiting ring groove 321, and thus reducing the frictional force between the upper surface of the limiting plate 610 and the side wall of the limiting ring groove 321.

[0056] refer to Figure 12In another embodiment of the present invention, the aerosol can cleaning device includes two limiting plates 610. The gap between the two limiting plates 610 is used for the movement of the pressure plate 320. The upper surfaces of the two limiting plates 610 are used to simultaneously abut against the upper inner wall of the limiting ring groove 321. It can be understood that the two limiting plates 610 can simultaneously abut against the upper inner wall of the limiting ring groove 321, so that the pressure plate 320 is subjected to uniform force, thereby enabling the pressure plate 320 to rise smoothly.

[0057] refer to Figure 7 and Figure 8 The gear 310 has multiple guide rods 330 parallel to the vertical direction, and the pressure plate 320 has multiple guide holes. The lower ends of the multiple guide rods 330 pass through the multiple guide holes, and multiple compression springs 340 are respectively sleeved on the multiple guide rods 330. It can be understood that the guide rods 330 on the gear 310 can abut against the inner wall of the guide holes on the pressure plate 320 to guide the vertical movement of the pressure plate 320, allowing the pressure plate 320 to rise and fall smoothly. On the other hand, when the gear 310 rotates around the axis of the turntable 100 and simultaneously rotates on its own axis, the gear 310 can drive the pressure plate 320 to rotate around the axis of the turntable 100 and simultaneously rotate on its own axis via the multiple guide rods 330. As an embodiment of the present invention, the guide rods 330 are bolts, and the guide holes are countersunk holes. The bolts pass through the countersunk holes and are threadedly fixed to the gear 310, allowing the pressure plate 320 to move vertically along the bolts. The large end of the bolt abuts against the bottom wall of the countersunk hole to prevent the pressure plate 320 from coming off the bolt. Multiple compression springs 340 are provided between the pressure plate 320 and the gear 310. The multiple compression springs 340 are respectively sleeved on multiple guide rods 330. The upper and lower ends of the compression springs 340 abut against the gear 310 and the pressure plate 320 respectively, and the compression springs 340 are always in a compressed state.

[0058] In an embodiment of the present invention, reference is made to Figure 1 and Figure 3The aerosol can cleaning equipment also includes a conveying device 500, which is used to deliver the aerosol cans 10 to be cleaned to the loading station 20 and to remove the aerosol cans 10 from the unloading station 30, so that the can-carrying tray 110 at the loading station 20 can support the aerosol cans 10 and cause the can-carrying tray 110 to rotate the aerosol cans 10 around the axis of the turntable 100 from the loading station 20 to the unloading station 30. The turntable 100 and the holder 300 rotate intermittently, and the conveying device 500 conveys intermittently. After one of the can-carrying trays 110 on the turntable 10 rotates to the loading station 20, it stops rotating. Then, the conveying device 500 simultaneously conveys multiple aerosol cans 10 to be cleaned, so that the last aerosol can 10 moves to the loading station 20 and then stops conveying. At this time, the aerosol can 10 at the loading station 20 is supported by the can-carrying tray 110 at the loading station 20. Then the turntable 100 continues to rotate. The next can tray 110 stops rotating after reaching the loading station 20. The conveyor 500 then simultaneously transports multiple aerosol cans 10 to be cleaned, moving the next aerosol can 10 to the loading station 20 before stopping, and so on. Further details are omitted here. Once the can tray 110 and the aerosol cans 10 on it have moved to the unloading station 30, the conveyor 500 can remove the aerosol cans 10 from the unloading station 30, transporting them to the heat shrink packaging equipment for heat shrink packaging.

[0059] refer to Figure 2 , Figure 4 , Figure 7 and Figure 8The aerosol can cleaning equipment also includes a can-pulling wheel 200, which is coaxially arranged with and connected to the turntable 100. The can-pulling wheel 200 is located between the turntable 100 and the retainer 300. The outer wall of the can-pulling wheel 200 is provided with multiple positioning grooves 210, which are respectively arranged with multiple can-carrying trays 110. The positioning grooves 210 are used to accommodate aerosol cans 10. When the turntable 100 drives the can-pulling wheel 200 to rotate, the positioning grooves 210 rotate sequentially to the loading station 20, the unloading station 30, and then rotate back to the loading station 20 and repeat in a cycle. In this embodiment of the invention, the retainer 300, the can-pulling wheel 200, and the turntable 100 are all coaxially arranged, and are mounted on the rotating shaft 120 from top to bottom. When the first rotational drive unit drives the rotating shaft 120 to rotate, the retainer 300, the can-pulling wheel 200, and the turntable 100 can rotate synchronously. Multiple positioning grooves 210 on the outer wall of the can-pulling wheel 200 are respectively corresponding to multiple can-carrying trays 110, that is, the multiple positioning grooves 210 are circumferentially distributed around the axis of the turntable 100 and the can-pulling wheel 200, so that the can-carrying tray 110, the positioning grooves 210, and the pressure plate 320 are correspondingly arranged. During the synchronous rotation of the turntable 100, the can-pulling wheel 200, and the retainer 300, the corresponding can-carrying tray 110, the positioning groove 210, and the pressure plate 320 first rotate to the loading station 20, then to the unloading station 30, and then back to the loading station 20, repeating this cycle. In this embodiment of the invention, the pressure plate 320 is columnar, and the axis of the pressure plate 320 coincides with the axis of the gear 310. The inner wall of the positioning groove 210 is an arc-shaped inner wall, and the axes of the corresponding can-carrying tray 110, the positioning groove 210, and the pressure plate 320 coincide.

[0060] After the conveying device 500 delivers the aerosol can 10 to the loading station 20, the aerosol can 10 at the loading station 20 enters the positioning groove 210 at the loading station 20. The aerosol can 10 at the loading station 20 is supported by the can-carrying tray 110 at the loading station 20 corresponding to the positioning groove 210, and the pressure plate 320, which is set corresponding to the positioning groove 210, is located above the aerosol can 10 at the loading station 20. After the aerosol can 10 enters the positioning groove 210, the arc-shaped inner wall of the positioning groove 210 abuts against the side wall of the aerosol can 10 to position the aerosol can 10, so that the axis of the aerosol can 10 can coincide with the axis of the can-carrying tray 110, the positioning groove 210 and the pressure plate 320, so that the pressure plate 320 can smoothly drive the aerosol can 10 and the can-carrying tray 110 to rotate. On the other hand, the side wall of the positioning groove 210 can provide some support for the aerosol can 10, preventing the aerosol can 10 from shaking after it moves to the loading station 20, and the pressure plate 320 can extend into the positioning groove 210.

[0061] As an embodiment of the present invention, the aerosol can cleaning device further includes a vacuum generating mechanism, which is mounted on the frame 600. A vacuum chamber is formed inside the can-pushing wheel 200. Multiple adsorption holes communicating with the vacuum chamber are evenly distributed on the side wall of the positioning groove 210. The vacuum generating mechanism is connected to the vacuum chamber via a vacuum rotary joint. The vacuum generating mechanism is used to create a negative pressure in the vacuum chamber, allowing the aerosol can 10 to be adsorbed onto the side wall of the positioning groove 210. It can be understood that after the vacuum chamber creates a negative pressure, the multiple adsorption holes on the side wall of the positioning groove 210 can adsorb the aerosol can 10 within the positioning groove 210, allowing the side wall of the aerosol can 10 to adhere to the side wall of the positioning groove 210, thereby improving the positioning effect of the aerosol can 10 on the side wall of the positioning groove 210.

[0062] refer to Figure 3 The conveying device 500 includes a first linear conveying mechanism 510, which is mounted on the frame 600. The end of the first linear conveying mechanism 510 is correspondingly positioned at the loading station 20. The first linear conveying mechanism 510 is used to drive multiple aerosol cans 10 to move sequentially to the loading station 20. It can be understood that the first linear conveying mechanism 510 is used to convey multiple aerosol cans 10 to be cleaned from back to front, and the first linear conveying mechanism 510 operates intermittently. When the can-carrying tray 110 rotates to the unloading station 30, the first linear conveying mechanism 510 drives multiple aerosol cans 10 to be cleaned to move simultaneously to the loading station 20, so that the aerosol cans 10 at the end of the first linear conveying mechanism 510 are pushed onto the can-carrying tray 110 by the remaining aerosol cans 10, and then the conveying stops. Further details are omitted here. The first linear conveyor mechanism 510 is a common first tracked conveyor mechanism, and the upper surface of the track of the first tracked conveyor mechanism is flush with the upper surface of the tank plate 110 and the turntable 100.

[0063] refer to Figure 3 and Figure 4The conveying device 500 includes a second linear conveying mechanism 520 and a guide plate 530, both mounted on the frame 600. The starting end of the second linear conveying mechanism 520 corresponds to the unloading station 30. The second linear conveying mechanism 520 is used to convey aerosol cans 10. The guide plate 530 has a guide arc surface 531 on the side facing the can-pulling wheel 200. The guide arc surface 531 is used to abut against the aerosol cans 10 at the unloading station 30, so that the aerosol cans 10 at the unloading station 30 move along the guide arc surface 531 to the starting end of the second linear conveying mechanism 520. It can be understood that the second linear conveying mechanism 520 is used to convey the aerosol cans 10 from back to front, and the end of the second linear conveying mechanism 520 corresponds to the heat shrink film packaging equipment. After the aerosol can 10 moves to the unloading station 30, the pressure plate 320 releases the aerosol can 10. With the synchronous rotation of the turntable 100 and the can-pushing wheel 200, the aerosol can 10 in the positioning groove 210 abuts against the guide arc surface 531 on the guide plate 530. The guide arc surface 531 guides the movement of the aerosol can 10, allowing it to leave the positioning groove 210 and move along the guide arc surface 531 to the beginning of the second linear conveyor mechanism 520. This allows the second linear conveyor mechanism 520 to deliver the cleaned aerosol can 10 to the heat shrink film packaging equipment. The second linear conveyor mechanism 520 can also be a common second tracked conveyor mechanism. In the second tracked conveyor mechanism, the upper surface of the track is located below the turntable 100, allowing the aerosol can 10 to land on the track in the second tracked conveyor mechanism when it leaves the positioning groove 210 and moves along the guide arc surface 531. The combination of the can-pulling wheel 200, the guide plate 530, and the guide arc surface 531 is a common configuration in the field of interval conveying of bottle-type workpieces, and will not be described further here.

[0064] refer to Figure 9 and Figure 10The brush device 400 includes multiple brush rollers 410, the lower ends of which are rotatably connected to the frame 600. The multiple brush rollers 410 are distributed along the edge of the turntable 100 and are used to clean the sidewalls of the aerosol can 10. It is understood that the multiple brush rollers 410 are distributed along the edge of the turntable 100 and are all located between the loading station 20 and the unloading station 30. The brush device 400 also includes a second rotary drive (not shown in the figure), which is connected to the multiple brush rollers 410, allowing the second rotary drive to simultaneously drive the multiple brush rollers 410 to rotate. This enables the multiple brush rollers 410 to scrape and brush the sidewalls of the aerosol can 10, which is clamped by the can-carrying tray 110 and the pressure plate 320, thereby achieving the purpose of cleaning the sidewalls of the aerosol can 10. The brush device 400 also includes a housing 420, a vacuum generating mechanism (not shown in the figure), and a filter (not shown in the figure). The housing 420 is mounted on the frame 600, with its opening facing the turntable 100. Parts of the structure of multiple brush rollers 410 extend into the housing 420. The vacuum generating mechanism is connected to the housing 420 via the filter. The vacuum generating mechanism creates a negative pressure in the housing 420, and the filter filters out impurities. It is understood that the vacuum generating mechanism creates a negative pressure inside the housing 420, allowing impurities adhering to the brushes of the brush rollers 410 to be sucked away, preventing the impurities from being transferred back to the side wall of the aerosol can 10, thus improving the cleaning effect of the brush rollers 410. The filter collects and filters impurities to prevent them from entering the vacuum generating mechanism. The vacuum generating mechanism can be a common vacuum pump, and the filter element is also a common filter component, which will not be further described here. In this embodiment of the invention, the vacuum generating mechanism is simultaneously connected to the vacuum chambers within the housing 420 and the can-turning wheel 200 via the filter.

[0065] refer to Figure 10 The brush device 400 also includes multiple levers 430 parallel to the vertical direction. These levers 430 are all housed within the housing 420. Each lever 430 abuts against the brushes of the multiple brush rollers 410, causing impurities attached to the brushes to be removed. Understandably, during the rotation of the brush rollers 410, the levers 430 within the housing 420 abut against the brushes, thus exerting a pulling action on the brushes and removing impurities. This achieves a cleaning effect on the brushes, preventing impurities from being transferred back to the side wall of the aerosol can 10, thereby improving the cleaning efficiency of the brush device 400.

[0066] In this embodiment of the invention, the angle of the fan-shaped area corresponding to the axis of the turntable 100 of the brush device 400 is 120°, and the number of teeth of the gear ring 350 is at least three times the number of teeth of the gear 310, so that the gear 310 rotates at least once in the area corresponding to the brush device 400, ensuring that the side wall of the aerosol can 10 can be completely brushed by the brush device 400. As a preferred embodiment of the invention, the ratio of the number of teeth of the gear ring 350 to the number of teeth of the gear 310 is equal to six, so that the gear 310 rotates twice in the area corresponding to the brush device 400, that is, the aerosol can 10 rotates twice in the area corresponding to the brush device 400, so that the brush device 400 can perform a more comprehensive cleaning of the side wall of the aerosol can 10.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
