Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a spray device and aluminum bottle cleaning equipment. Background Technology

[0002] The vehicle's air suspension is located on the front and rear wheel sides, clamped between the vehicle body and axle sides. In terms of air suspension, when compressed air is supplied or discharged, the air suspension can expand or contract vertically according to the air supply and discharge volume (compressed air quantity) to adjust the vehicle height. The air tank is a crucial component of the automotive air suspension system. The tank body is typically fixed to the vehicle frame via a bracket, which supports the tank body and is welded to the frame, thus mounting the air tank onto the frame.

[0003] Existing air suspension systems generally use aluminum cylinders as air reservoirs. If impurities from the inner cavity of the aluminum cylinder enter the air circuit of the air suspension system, it will adversely affect the overall vehicle safety or the reliability of the chassis air suspension system (see Chinese Patent Application No. 202322305729.7, "An Air Reservoir for Vehicle Air Suspension"). Therefore, aluminum cylinders need to be cleaned before use. Furthermore, different air suspension systems require aluminum cylinders of different sizes as air reservoirs.

[0004] To perform batch cleaning of the inner cavity of bottles, Chinese patent application number 201821587240.6, entitled "An Integrated Washing and Brushing Bottle Washing Machine," provides an integrated washing and brushing bottle washing machine, including a base and a step-rotating bottle-holding turntable mounted on the base. The bottle-holding turntable includes a first station, a second station, a third station, and a fourth station. One or more bottle-holding sleeves are provided at corresponding positions of each station on the bottle-holding turntable. A first groove is provided on the bottle-holding sleeve, penetrating the bottle-holding sleeve and the bottle-holding turntable. A first nozzle, a brush body, and a second nozzle are provided on the base, respectively corresponding to the second station, the third station, and the fourth station. The first nozzle, the brush body, and the second nozzle are positioned directly below the first groove, and the brush body can pass through the first groove to perform vertical reciprocating motion. This structure, with the bottle inverted on the bottle holder at the first station, cleaning agent sprayed inside the bottle at the second station, the inside of the bottle scrubbed with a brush at the third station, and the inside of the bottle rinsed with clean water at the fourth station, results in better bottle cleaning. During the cleaning process, the bottle remains inverted, eliminating the redundant steps of righting and then inverting it again, thus improving cleaning efficiency. Furthermore, wastewater is more easily drained from the bottle opening, preventing residue on the inner wall and resulting in a cleaner finish. In continuous operation, all stations operate synchronously, further enhancing cleaning efficiency.

[0005] However, the above solution is mainly used for cleaning relatively small household bottles, while aluminum bottles are much larger than household bottles. If the nozzle is fixed directly below the aluminum bottle, the upper space inside the aluminum bottle cannot be sprayed, making it impossible to clean the inner cavity of the aluminum bottle in all directions. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to provide a spray device for aluminum bottle cleaning equipment that can perform all-round cleaning of the inner cavity of aluminum bottles, in view of the current state of the prior art.

[0007] The second technical problem to be solved by this utility model is to provide an aluminum bottle cleaning device that uses the above-mentioned spraying device.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a spraying device for aluminum bottle cleaning equipment, used to spray cleaning medium into the inner cavity of an aluminum bottle inverted at the spraying station of the aluminum bottle cleaning equipment, characterized in that: it includes...

[0009] The spray pipe extends vertically and has spray holes around its perimeter; and

[0010] The second driving component is used to drive the spray pipe to rise and fall, so that the spray pipe extends into the inner cavity of the aluminum bottle located at the corresponding spraying station.

[0011] To accommodate the cleaning needs of aluminum bottles of different sizes, the spray pipe includes a first fixed pipe and multiple first replacement pipes of different lengths that are detachably installed on the top of the first fixed pipe. The power output end of the second drive unit is drivenly connected to the first fixed pipe.

[0012] To facilitate the supply of cleaning media, a cleaning media supply box is also included for supplying cleaning media to the spray pipe.

[0013] To facilitate the recycling of cleaning media, a cleaning media recycling bin is also included. The top of the recycling bin is open and faces the opening of the aluminum bottle located at the corresponding spray station.

[0014] To simplify the structure, the cleaning medium supply box and the cleaning medium recovery box of each of the spray devices are in the same box.

[0015] To improve the cleaning effect, the cleaning medium supply tank is equipped with a heating element for heating the cleaning medium.

[0016] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an aluminum bottle cleaning device, comprising...

[0017] The workbench, in sequence according to the process flow, has a loading station, at least one spraying station, and a unloading station; and

[0018] The conveying device is used to transport the inverted aluminum bottles from the loading station to the spraying station and the unloading station in sequence.

[0019] The feature is that: the above-mentioned spraying device is also used, the number of which is at least one, and it corresponds to the spraying station, with each spraying device located at the corresponding spraying station.

[0020] To sequentially perform preliminary cleaning, deep alkaline cleaning, and rinsing of the aluminum bottle's inner cavity, three spray stations are designated as the first, second, and third spray stations according to the process flow. The cleaning medium sprayed by the spray pipes corresponding to the first and third spray stations is clean water, while the cleaning medium sprayed by the spray pipe corresponding to the second spray station is alkaline water.

[0021] To prevent the spraying device from being activated when there are no aluminum bottles at the corresponding workstation, at least one proximity sensor corresponding to the spraying workstation is also included to monitor whether there are aluminum bottles at the corresponding spraying workstation.

[0022] The aluminum bottle cleaning equipment has a controller, and the proximity sensor and the spray device are both electrically connected to the controller so that the controller can receive the signal collected by the proximity sensor and control the opening and closing of the spray device.

[0023] This avoids both the waste of cleaning media and the splashing of cleaning media.

[0024] To improve equipment compactness and save a workstation, the loading station, spraying station, and unloading station are arranged sequentially and at intervals along the circumference, and the loading station and unloading station share the same workstation.

[0025] Compared with the prior art, the advantages of this utility model are as follows: the spray pipe is driven to rise and fall by the second driving component. On the one hand, the spray pipe can be extended into the inner cavity of the aluminum bottle located at the corresponding spraying station so that the cleaning medium in the spray pipe can be sprayed onto the inner wall of the aluminum bottle through the spray hole. On the other hand, during the spraying process, the spray pipe can be reciprocated to expand the spraying range, thereby achieving all-round cleaning of the inner cavity of the aluminum bottle.

[0039] like Figures 1 to 11 The image shows a preferred embodiment of the aluminum bottle cleaning equipment of this utility model. The aluminum bottle cleaning equipment includes a workbench 1, a conveying device 2, a spraying device 3, an air blowing device 4, a position monitoring device 5, and a proximity sensor 6.

[0040] Among them, such as Figure 3As shown, the workbench 1 has, in the order of the process flow, a loading station A, a first spraying station B1, a second spraying station B2, a third spraying station B3, a first air blowing station C1, a second air blowing station C2, and a unloading station D arranged at equal angular intervals along the circumference. In this embodiment, the loading station A and the unloading station D share the same station. The first spraying station B1, the second spraying station B2, and the third spraying station B3 are collectively referred to as spraying station B, and the first air blowing station C1 and the second air blowing station C2 are collectively referred to as air blowing station C.

[0041] The conveying device 2 is used to sequentially transport the inverted aluminum bottle 10 from the loading station A to the first spraying station B1, the second spraying station B2, the third spraying station B3, the first air blowing station C1, the second air blowing station C2, and the unloading station D. In this embodiment, as shown... Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the conveying device 2 includes a first rotating disk 21, a first positioning seat 22, a second rotating disk 23, a second positioning seat 24, a pressing module 25, a rotating mechanism 26, a lifting mechanism 27, and a conductive slip ring 28.

[0042] Specifically, the first rotating disk 21 is rotatably mounted on the workbench 1; the top of the first rotating disk 21 is provided with multiple vertically arranged guide rods 211;

[0043] The six first positioning seats 22 are arranged at equal angular intervals around the periphery of the first rotating disk 21; each first positioning seat 22 has an insertion hole 221 arranged vertically through it for inserting the neck of the inverted aluminum bottle 10.

[0044] The second rotating disk 23 is movably mounted directly above the first rotating disk 21 and is coaxially arranged with the first rotating disk 21 and can rotate synchronously with the first rotating disk 21; the second rotating disk 23 is provided with guide sleeves 231 corresponding to the guide rods 211 one by one, and each guide sleeve 231 can slide up and down and be sleeved on the outer periphery of the corresponding guide rod 211, thereby realizing the stable sliding of the second rotating disk 23 in the vertical direction;

[0045] There are six second positioning seats 24, which are arranged at equal angular intervals around the periphery of the second rotating disk 23 and correspond one-to-one with the first positioning seats 22. Each second positioning seat 24 can move radially along the second rotating disk 23 to meet the side support requirements of aluminum bottles of different diameters. In this embodiment, each second positioning seat 24 includes a connecting arm 241 extending radially along the second rotating disk 23 and two support arms 242 extending outward from the tail end of the connecting arm 241 and arranged at an angle. The two support arms 242 are used to abut against the side of the inverted aluminum bottle 10. In addition, the connecting arm 241 has two parallel strip holes 2411 extending along its length. The periphery of the second rotating disk 23 has a plurality of connecting holes 232 corresponding one-to-one with the strip holes 2411. The second positioning seats 24 and the second rotating disk 23 are connected to each other through the strip holes 2411 and the connecting holes 232 and fixed by screws (not shown in the figure) as fasteners.

[0046] There are six clamping modules 25, which are arranged at equal angular intervals around the periphery of the second rotating disk 23 and correspond one-to-one with the first positioning seat 22. Each clamping module 25 includes a clamping block 251 for clamping the top of the inverted aluminum bottle 10 and a first driving member 252 for driving the clamping block 251 to rise and fall.

[0047] The rotating mechanism 26 is used to drive the first rotating disk 21 to rotate intermittently;

[0048] The lifting mechanism 27 is used to drive the second rotating disk 23 to rise and fall, so that the pressing module 25 can meet the pressing requirements of aluminum bottles of different heights. In this embodiment, the lifting mechanism 27 includes a fixed seat 271, a movable seat 272, and a lead screw 273. The fixed seat 271 is installed on the top of each guide rod 211. The movable seat 272 is installed directly above the second rotating disk 23 via a mounting rod. The lead screw 273 extends vertically, with its first end rotatably connected to the movable seat 272 and its second end having an operating part 2731. The fixed seat 271 is threadedly connected to the outer periphery of the lead screw 273. In use, by holding the operating part 2731 and rotating the lead screw 273, since the fixed seat 271 is threadedly connected to the outer periphery of the lead screw 273, the lead screw 273 will drive the second rotating disk 23 to rise and fall synchronously via the movable seat 272.

[0049] A conductive slip ring 28 is installed in the middle of the first rotating disk 21, and its axis extends vertically. The inner ring of the conductive slip ring 28 is fixed to the worktable 1 and is electrically connected to an external power supply through a wire. The outer ring of the conductive slip ring 28 is fixed to the first rotating disk 21 and is electrically connected to the first driving member 252 through a wire, thereby preventing the wire used to supply power to the first driving member 252 from getting tangled when the second rotating disk 23 rotates synchronously with the first rotating disk 21.

[0050] There are three spray devices 3, each corresponding to one of the spray stations B. Each spray device 3 is located at its corresponding spray station B and is used to spray cleaning medium into the inner cavity of the aluminum bottle 10 that has been moved to that spray station B. In this embodiment, as shown... Figure 4 and Figure 7 As shown, each spraying device 3 includes a spray pipe 31, a second drive component 32, a cleaning medium supply box 33, and a cleaning medium recovery box 34.

[0051] Specifically, the spray pipe 31 extends vertically and includes a first fixed pipe 311 and multiple first replacement pipes 312 of different lengths that are detachably installed on the top of the first fixed pipe 311, in order to meet the spraying requirements of aluminum bottles 10 of different heights. The first fixed pipe 311 and the first replacement pipe 312 are provided with multiple spaced spray holes 310 around their periphery.

[0052] The power output end of the second driving component 32 is connected to the first fixed tube 311 to drive the entire spray pipe 31 to rise and fall, so that the spray pipe 31 extends into the inner cavity of the aluminum bottle 10 that has moved to the corresponding spraying station B.

[0053] A cleaning medium supply tank 33 is located at the bottom of the workbench 1 and is used to supply cleaning medium to the spray pipe 31. The cleaning medium supply tank 33 is equipped with a heating element 331 for heating the cleaning medium. In this embodiment, the cleaning medium stored in the cleaning medium supply tank 33 corresponding to the first spray station B1 and the third spray station B3 is clean water, and the cleaning medium stored in the cleaning medium supply tank 33 corresponding to the second spray station B2 is alkaline water. Therefore, the cleaning medium sprayed by the spray pipe 31 corresponding to the first spray station B1 and the third spray station B3 is clean water, and the cleaning medium sprayed by the spray pipe 31 corresponding to the second spray station B2 is alkaline water, thereby sequentially realizing the preliminary cleaning, deep alkaline washing and rinsing of the inner cavity of the aluminum bottle 10.

[0054] The cleaning medium recovery box 34 is located at the bottom of the workbench 1, and its top has an open opening that faces the bottle mouth of the aluminum bottle 10 that is moved to the corresponding spray station B. In this embodiment, the cleaning medium supply box 33 and the cleaning medium recovery box 34 of each spray device 3 are the same box, and the user needs to replace the cleaning medium regularly.

[0055] There are two air blowing devices 4, corresponding one-to-one with the air blowing stations C. Each air blowing device 4 is located at its corresponding air blowing station C and is used to blow air into the inner cavity of the aluminum bottle 10 that has moved to that air blowing station C. In this embodiment, as shown... Figure 4 and Figure 7 As shown, each air blowing device 4 includes an air blowing pipe 41, a second driving member 32, and an external gas supply device (not shown in the figure).

[0056] Specifically, the air blowing pipe 41 extends vertically and includes a second fixed pipe 411 and a plurality of second replacement pipes 412 of different lengths that are detachably installed on the top of the second fixed pipe 411, in order to meet the air blowing requirements of aluminum bottles 10 of different heights. The second fixed pipe 411 and the second replacement pipe 412 are provided with a plurality of spaced air outlets 410 around their periphery.

[0057] The power output end of the second driving component 32 is connected to the second fixed tube 411 to drive the entire blowing tube 41 to rise and fall, so that the blowing tube 41 extends into the inner cavity of the aluminum bottle 10 that has moved to the corresponding blowing station C.

[0058] The gas supply device is used to supply gas to the blowing pipe 41. In this embodiment, the gas supplied by the gas supply device corresponding to the first blowing station C1 is high-pressure gas, and the gas supplied by the gas supply device corresponding to the second blowing station C2 is high-temperature gas. Therefore, the gas blown out by the blowing pipe 41 corresponding to the first blowing station C1 is high-pressure gas, and the gas blown out by the blowing pipe 41 corresponding to the second blowing station C2 is high-temperature gas, thereby sequentially blowing off and drying the residual moisture on the inner wall of the aluminum bottle 10.

[0059] The position monitoring device 5 is used to monitor whether the first rotating disk 21 has rotated into position. In this embodiment, as... Figure 3 and Figure 6 As shown, the position monitoring device 5 includes a trigger module 51 and a sensing module 52.

[0060] Specifically, there are six sets of trigger modules 51, which is consistent with the number of workstations mentioned above, and they are arranged at equal angular intervals along the circumference on the first rotating disk 21. In this embodiment, each trigger module 51 includes three mounting holes arranged at radial intervals along the first rotating disk 21 as trigger positions 511, and at least one mounting hole is provided with a bolt as a trigger element 512. The arrangement and combination of trigger elements 512 in each set of trigger modules 51 are different.

[0061] The sensing module 52 is located on the workbench 1. When the first rotating disk 21 is rotated into position, the sensing module 52 is triggered by one of the triggering modules 51. In this embodiment, the sensing module 52 includes three proximity sensors as sensing elements 521 that correspond one-to-one with the triggering position 511. When the first rotating disk 21 is rotated into position, each sensing element 521 is facing the corresponding triggering position 511 and can sense whether there is a triggering element 512 at the triggering position 511.

[0062] In this way, every time the first rotating disk 21 rotates once (rotation angle is 60°), the three sensors 521 of the sensing module 52 can sense whether there is a trigger 512 at the corresponding trigger position 511, and at least one sensor 521 will be triggered by the corresponding trigger 512. On the one hand, it can monitor whether the first rotating disk 21 has rotated to the correct position, and on the other hand, it can monitor the specific angle of rotation of the first rotating disk 21 relative to the initial position.

[0063] There are five proximity sensors 6, corresponding one-to-one with the spray station B and the air blowing station C mentioned above; for example Figure 2 As shown, each proximity sensor 6 is installed on the outside of the corresponding workstation, and can detect whether there is an aluminum bottle 10 at the corresponding spraying workstation B and blowing workstation C.

[0064] In addition, the above-mentioned aluminum bottle cleaning equipment has a controller. The above-mentioned sensing module 52, proximity sensor 6, spray device 3, air blowing device 4 and rotating mechanism 26 are all electrically connected to the controller, so that the controller can receive the signal collected by the sensing module 52 and control the opening and closing of the rotating mechanism 26, and can also receive the signal collected by the proximity sensor 6 and control the opening and closing of the spray device 3 and air blowing device 4.

[0065] The working principle of this embodiment is as follows:

[0066] (1) Before cleaning, loosen the fasteners between the second positioning seat 24 and the second rotating disk 23, then move the second positioning seat 24 radially along the second rotating disk 23 to a suitable position and tighten the fasteners. At the same time, hold the operating part 2731 and rotate the screw 273 to drive the second rotating disk 23 to rise and fall to a suitable height. Replace the first replacement tube 312 and the second replacement tube 412 of suitable length for the spray device 3 and the blowing device 4 respectively to meet the cleaning requirements of the aluminum bottle 10 of the corresponding size.

[0067] (2) During cleaning, the rotating mechanism 26 drives the first rotating disk 21 and the second rotating disk 23 to rotate intermittently, and works in conjunction with each spraying device 3 and blowing device 4 under the control of the controller. Each time the first rotating disk 21 and the second rotating disk 23 rotate once, each spraying device 3 and blowing device 4 completes one operation, thereby completing one cleaning of the aluminum bottle 10. Since there are six workstations on the workbench 1, the first rotating disk 21 and the second rotating disk 23 can complete six cleanings in one rotation, which is highly efficient.

[0068] Taking the cleaning of an aluminum bottle (e.g., 10) as an example, it requires seven steps:

[0069] ① After inverting the aluminum bottle 10, insert it into the insertion hole 221 of the first positioning seat 22 located at the loading station A, so that the side of the aluminum bottle 10 abuts against the two support arms 242 of the second positioning seat 24. Then, the first driving member 252 drives the pressing block 251 to descend and press against the top of the aluminum bottle 10, thereby completing the loading and positioning of the aluminum bottle 10.

[0070] ② The rotating mechanism 26 drives the first rotating disk 21 to rotate once to transport the aluminum bottle 10 to the first spraying station B1. The spraying device 3 corresponding to the first spraying station B1 starts to work. First, the second driving member 32 drives the spray pipe 31 to rise and extend into the inner cavity of the aluminum bottle 10. Then, the cleaning medium supply box 33 supplies clean water to the spray pipe 31 and sprays it onto the inner wall of the aluminum bottle 10 through the spray hole 310. During the spraying process, the second driving member 32 drives the spray pipe 31 to move up and down to expand the spraying range. After the spraying is completed, the second driving member 32 drives the spray pipe 31 to fall down and get out of the inner cavity of the aluminum bottle 10 to avoid interference with the subsequently rotating first rotating disk 21, thereby completing the initial cleaning of the inner cavity of the aluminum bottle 10.

[0071] ③ The rotating mechanism 26 drives the first rotating disk 21 to rotate once to transport the aluminum bottle 10 to the second spray station B2. The spray device 3 corresponding to the second spray station B2 starts to work. Its working process is the same as step ②, except that the cleaning medium sprayed in this process is alkaline water, thereby completing the deep alkaline washing of the inner cavity of the aluminum bottle 10.

[0072] ④ The rotating mechanism 26 drives the first rotating disk 21 to rotate once to transport the aluminum bottle 10 to the third spray station B3. The spray device 3 corresponding to the third spray station B3 starts to work. Its working process is the same as step ②, thereby completing the rinsing of the inner cavity of the aluminum bottle 10.

[0073] ⑤ The rotating mechanism 26 drives the first rotating disk 21 to rotate once to transport the aluminum bottle 10 to the first blowing station C1. The blowing device 4 corresponding to the first blowing station C1 starts to work. First, the third driving member 42 drives the blowing pipe 41 to rise and extend into the inner cavity of the aluminum bottle 10. Then, the gas supply device supplies high-pressure gas to the blowing pipe 41 and blows it towards the inner wall of the aluminum bottle 10 through the air outlet 410. During the blowing process, the third driving member 42 drives the blowing pipe 41 to move up and down to expand the blowing range. After the blowing is completed, the third driving member 42 drives the blowing pipe 41 to fall and detach from the inner cavity of the aluminum bottle 10 to avoid interference with the subsequently rotating first rotating disk 21, thereby completing the blowing off of residual moisture from the inner wall of the aluminum bottle 10.

[0074] ⑥ The rotating mechanism 26 drives the first rotating disk 21 to rotate once to transport the aluminum bottle 10 to the second blowing station C2. The blowing device 4 corresponding to the second blowing station C2 starts to work. Its working process is the same as step ⑤, except that the gas blown out in this process is high temperature gas, thereby completing the drying of the inner wall of the aluminum bottle 10.

[0075] ⑦ The rotating mechanism 26 drives the first rotating disk 21 to rotate once to transport the aluminum bottle 10 to the unloading station D (i.e., reset to the loading station A). The first driving component 252 drives the clamping block 251 to rise to release the clamping on the aluminum bottle 10, and then the inverted aluminum bottle 10 is taken out.

[0076] This completes the cleaning of one aluminum bottle 10.
