Description

[0002] In the aluminum alloy production process, in order to improve the service life of the profiles, it is necessary to perform an oxidation treatment on the surface of the profiles. Under normal circumstances, the profiles need to be placed in an acidic oxidation bath to form an oxide film on the surface of the profiles.

[0003] After the profiles come out of the oxidation tank, they need to be cleaned with warm water at 40℃-50℃ to age the film layer and accelerate the removal of impurities and grease. In order to avoid the film layer from thinning and the color from fading, the time needs to be controlled between 0.5 and 1 minute.

[0004] Normally, the profile cleaning process is carried out in a cleaning tank containing bubbling clean water. After the profiles come out of the oxidation tank, they need to be gradually immersed in the cleaning tank. During the placement of the profiles, the bottom profiles enter the cleaning tank first, followed by the top profiles. When the profiles are removed, the top profiles come out of the clean water first, followed by the bottom profiles. Therefore, the cleaning time for the bottom profiles is longer than that for the top profiles. There may be some color difference between the bottom and top of the same batch of profiles.

[0005] Therefore, how to design a cleaning device to reduce the color difference of profiles has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0040] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0041] As shown in Figure 1 and Figure 2 , it comprises a cleaning cylinder 1, wherein the bottom of the cleaning cylinder 1 is provided with a drain 12, and a touch pressure component 2 for carrying the oxidized profile is installed at the drain 12, and the inside of the cleaning cylinder 1 is further provided with a plurality of circumferentially distributed cleaning mechanisms 3, wherein the water sprayed by the cleaning mechanisms 3 is directed to the axial position of the cleaning cylinder 1.

[0042] It further comprises a central control unit 7, wherein the cleaning mechanisms 3 and the touch pressure component 2 are electrically connected to the central control unit 7.

[0043] Through the above arrangement, when the profile comes out of the oxidation tank, the profile is placed on the touch pressure component 2 of the cleaning cylinder 1, at this time, the touch pressure component 2 is turned on and sends a signal to the central control unit 7 that the profile has entered, and the central control unit 7 controls the cleaning mechanisms 3 to work, so as to spray warm water to the oxidized profile inside the cleaning cylinder 1, realizing the cleaning of the surface of the oxidized profile and accelerating the aging of the surface film of the profile. When the profile is separated from the touch pressure component 2, the central control unit 7 controls the cleaning mechanisms 3 to stop working at this time, thereby completing the cleaning of the oxidized profile.

[0044] This kind of cleaning method of oxidized profile can make the cleaning time of the profile consistent and reduce the risk of different colors of the same batch of profiles.

[0045] It is worth mentioning here that the time of profile cleaning inside the cleaning cylinder 1 can be controlled by the mechanism for lifting the profile, and the cleaning of the profile is immediately stopped after the profile is lifted from the contact pressure part 2.

[0046] Specifically, in the embodiment, as shown in Figure 2 and Figure 3 , the cleaning mechanism 3 includes a water supply main pipe 31, a water supply branch pipe 32 and a water spraying head 33, wherein the water supply branch pipe 32 is connected with the water supply main pipe 31, the other end of the water supply branch pipe 32 extends into the inner cavity of the cleaning cylinder 1 and is connected with the water spraying head 33, and specifically, the spray holes of the water spraying head 33 are directed to the axial position of the cleaning cylinder 1, which is convenient for the cleaning of the oxidized profile.

[0047] In the embodiment, as shown in Figure 1 and Figure 3 , the cleaning mechanism 3 is provided with several groups and is uniformly distributed around the circumference of the cleaning cylinder 1, and the plurality of cleaning mechanisms 3 are arranged around the oxidized profile, which can realize multi-angle cleaning of the oxidized profile.

[0048] In order to be able to provide water source to the water spraying head 33, in the embodiment, as shown in Figure 1 and Figure 2 , a water supply part 5 is further included, wherein the water supply part 5 is a water tank, the water supply main pipe 31 is connected with the water tank, and the water tank is used to send water to the plurality of water supply main pipes 31 on the circumference of the cleaning cylinder 1.

[0049] When the oxidized profile is on the contact pressure part 2, in order to be able to make the central control unit 7 control the water spraying head 33 to spray warm water, in the embodiment, as shown in Figure 1 and Figure 2 , a water supply switch 6 is further installed on the water tank, wherein one end of the water supply switch 6 is connected with the water tank, and the other end is connected with the water source outside, wherein the water supply switch 6 is in a normally closed state, and the water supply switch 6 is electrically connected with the central control unit 7.

[0050] It is worth mentioning here that the water tank always keeps the water source full, when the contact pressure part 2 sends a signal to the central control unit 7 that the profile enters, at this time the central control unit 7 controls the water supply switch 6 to open, the water source outside will be sent into the water tank, at this time the water in the water tank will be sprayed from the water spraying head 33 through the water supply main pipe 31 and the water supply branch pipe 32, realizing the cleaning operation of the oxidized profile, and during the cleaning process, the water source outside can be continuously sent into the water tank through the water supply switch 6, so as to ensure that there is enough pressure in the water tank to make the water sprayed from the water spraying head 33, when the profile on the contact pressure part 2 is separated, at this time the central control unit 7 controls the water supply switch 6 to close, preventing the water outside from entering the water tank, at this time the water spraying head 33 has no water to spray.

[0051] In order to further improve the cleaning effect of the oxidized profile, in the embodiment, as shown in Figure 1 andFigure 2 As shown, a driving mechanism 4 is arranged to drive the cleaning mechanism 3 to swing, specifically, the driving mechanism 4 comprises a rotating table 41, a gear ring 42, a gear 43 and a driving motor 44, wherein the rotating table 41 is rotatably installed on the outer lateral wall of the cleaning barrel 1, the gear ring 42 is fixedly installed on the rotating table 41, the gear 43 is fixedly connected with the output shaft of the driving motor 44, and the water supply main pipe 31 is fixedly installed on the rotating table 41.

[0052] Specifically, the driving motor 44 is a step motor, which can control the rotation angle of the rotating table 41, and the driving motor 44 is electrically connected with the central control unit 7, and the driving motor 44 is reciprocated and reversed to realize the swing of the water spraying head 33, change the position of the water spraying head 33 in the inner cavity of the cleaning barrel 1, and improve the cleaning effect on the oxidized profile.

[0053] Since the driving mechanism 4 can drive the water supply main pipe 31 to swing reciprocally, and the other end of the water supply main pipe 31 needs to be connected with the water tank to supply clean water to the water supply main pipe 31, in this embodiment, the water supply main pipe 31 is connected with the water tank through a hose.

[0054] It is worth mentioning here that since the driving motor 44 drives the rotating table 41 to swing in a small angle range, the hose can be bent to supply the water in the water tank to the water supply main pipe 31, and since the rotation angle of the water supply main pipe 31 is small, the hose will not be wound around the outer side of the cleaning barrel 1, and the supply of warm water is realized smoothly.

[0055] When the water supply main pipe 31 swings under the drive of the rotating table 41, the water supply branch pipe 32 will rotate along the axis of the cleaning barrel 1, and in this embodiment, as shown in the figure, the lateral wall of the cleaning barrel 1 is provided with an avoiding groove 11, wherein the water supply branch pipe 32 extends into the inner cavity of the cleaning barrel 1 through the avoiding groove 11, so that the cleaning mechanism 3 can swing reciprocally. Figure 3 Since a plurality of avoiding grooves 11 are arranged on the lateral wall of the cleaning barrel 1, when the water spraying head 33 sprays warm water outward, the water sprayed by the water spraying head 33 on the opposite side is easy to pass out from the avoiding groove 11, which will cause a large amount of warm water to splash out of the cleaning barrel 1, in order to solve this problem, in this embodiment, as shown in the figures, a shielding barrel 8 is further included, wherein the shielding barrel 8 coincides with the axis of the cleaning barrel 1, the shielding barrel 8 is installed on the water supply branch pipe 32 and blocks the avoiding groove 11 to prevent water from splashing out of the cleaning barrel 1.

[0056] Figure 2 Figure 3

[0057] ​​​Specifically, the shielding cylinder 8 is set in the inner cavity of the cleaning cylinder 1 and is rotatably connected to the cleaning cylinder 1. The water spray head 33 is located in the inner cavity of the shielding cylinder 8. The water sprayed by the water spray head 33 is shielded by the shielding cylinder 8 and remains in the inner cavity of the cleaning cylinder 1. Finally, it flows out of the cleaning cylinder 1 from the drain outlet 12 to prevent water from accumulating inside the cleaning cylinder 1.

[0058] In this embodiment, as Figure 4 As shown, the anodized profile being processed here is an aluminum tube. Several aluminum tubes are clamped by a fixing frame, and the fixing frame and the aluminum tubes are simultaneously placed into the anodizing tank for oxidation. Then, the profile is placed into the cleaning cylinder 1 by the fixing frame.

[0059] Among them, such as Figure 4 and Figure 5 As shown, the touch-pressing component 2 includes a touch-pressing platform 21, wherein the touch-pressing platform 21 is provided with a touch-pressing cavity 211 extending vertically, wherein a touch-pressing switch 22 is provided in the touch-pressing cavity 211, and wherein the touch-pressing switch 22 is electrically connected to the central control unit 7.

[0060] When the end of the fixing bracket is inserted into the pressure chamber 211, the fixing bracket contacts the pressure switch 22, thereby turning on the pressure switch 22, so that the drive motor 44 and the water supply switch 6 can be controlled by the central control unit 7.

[0061] Specifically, the pressure switch 22 is fixedly installed inside the pressure cavity 211.

[0062] It is worth noting that the top wall of the pressure table 21 is provided with a guide slope 212 that communicates with the pressure cavity 211, wherein the guide slope 212 is engaged with the interior of the pressure cavity 211.

[0063] Specifically, the opening of the guide slope 212 is upward and funnel-shaped, which can guide the fixing frame into the pressure chamber 211, making it convenient for the fixing frame to be inserted and positioned.

[0064] Since the pressure chamber 211 runs through the top and bottom, during the cleaning process of the oxidized profile, the water sprayed from the spray head 33 can flow into the pressure chamber 211 from the guide slope 212, and then flow out through the bottom of the pressure chamber 211.

[0065] In this embodiment, in order to install the touch switch 22, as follows: Figure 6 As shown, the bottom of the pressure plate 21 is provided with a positioning groove 213 that communicates with the pressure cavity 211. Specifically, there are four positioning grooves 213 that are evenly distributed along the circumference of the pressure plate 21. The positioning groove 213 is provided with a positioning block 214 that is fixed by bolts. The positioning block 214 extends into the inside of the pressure cavity 211, thereby encapsulating the pressure switch 22 in the pressure cavity 211.

[0066] Among them, such asFigure 5 and Figure 6 As shown in the figure, the touch switch 22 includes a positioning seat 224, a protective cap 225 sleeved outside the positioning seat 224 and connected with the touch table 21 along the axis of the touch table 21, a touch column 222 vertically extending downwards is fixedly arranged on the inner wall of the protective cap 225, a touch head 221 electrically connected with the central control unit 7 is fixedly arranged in the positioning seat 224, wherein the touch head 221 is located directly below the touch column 222, and a spring 223 is sleeved outside the touch column 222, one end of the spring 223 is connected with the protective cap 225, and the other end of the spring 223 is connected with the positioning seat 224, and specifically, the spring 223 is a compression spring to separate the touch head 221 from the touch column 222.

[0067] As shown in the figure, the longitudinal surface of the top end of the protective cap 225 is isosceles trapezoidal, and is matched with the top wall of the touch cavity 211, when the profile is not placed on the touch part 2, the top of the protective cap 225 abuts against the top wall of the touch cavity 211, at this time the touch column 222 is separated from the touch head 221.

[0068] When the profile is placed on the touch part 2, at this time the protective cap 225 moves downwards and compresses the spring 223, at this time part of the water passes through the touch cavity 211, in order to avoid the water entering the touch switch 22 from the gap between the protective cap 225 and the positioning seat 224 and contacting the touch head 221, in the embodiment, as shown in the figure, a flow guide cover 2241 is fixedly arranged on the inner wall of the positioning seat 224, wherein the flow guide cover 2241 is arranged obliquely, the flow guide cover 2241 and the top wall of the positioning seat 224 enclose a mounting cavity 2243, wherein the touch head 221 is mounted in the mounting cavity 2243, and the top of the flow guide cover 2241 is further provided with a guide hole 2244 for the touch column 222 to extend into the mounting cavity 2243. Figure 5

[0069] As shown in the figure, the longitudinal surface of the top end of the protective cap 225 is isosceles trapezoidal, and is matched with the top wall of the touch cavity 211, when the profile is not placed on the touch part 2, the top of the protective cap 225 abuts against the top wall of the touch cavity 211, at this time the touch column 222 is separated from the touch head 221.
