Description

Technical Field

[0001] The invention relates to the technical field of aluminum material processing, and in particular to a surface processing technology of a curtain wall aluminum profile. Background Art

[0002] The building curtain wall is composed of panels and supporting structure systems (supporting devices and supporting structures), which can have a certain displacement ability relative to the main structure or a certain deformation ability, and is suspended on the main structure, and does not bear structural loads and effects. Aluminum alloy is a material used in large quantities in curtain wall projects. The metal rods of curtain walls are mainly aluminum alloy building profiles (accounting for more than 95%). Compared with other metal materials, aluminum and aluminum alloys have the following characteristics: 1) Low density: The density of aluminum and aluminum alloys is close to 2.7g / , which is about 1 / 3 of iron or copper; 2) High strength: After a certain degree of cold processing, the matrix strength can be strengthened, and some grades of aluminum alloys can also be strengthened by heat treatment. 3) Good electrical and thermal conductivity: The electrical and thermal conductivity of aluminum is second only to silver, copper and gold. 4) Good corrosion resistance: The surface of aluminum is easy to naturally produce a dense and firm AL2O3 protective film, which can well protect the matrix from corrosion. 5) Easy to process: After adding certain alloying elements, cast aluminum alloys with good casting properties or deformed aluminum alloys with good processing plasticity can be obtained. Therefore, the selection of aluminum alloy profiles, surface treatment, cross-section design, etc. play a very important role in the performance of curtain walls.

[0003] Since building curtain walls are mostly exposed to the external environment during use, in order to improve the surface quality of building curtain wall aluminum profiles, increase the acid resistance, alkali resistance and wear resistance of curtain wall aluminum profiles, and ensure the service life of curtain wall aluminum profiles, most existing technologies use electrophoresis technology to achieve this goal.

[0004] In the prior art, the electrophoresis process for aluminum profiles is mostly performed by fixing multiple sections of aluminum profiles to be electrophoresed with the mounting frame on the crane through clamps or aluminum wires during operation, thereby achieving the installation and fixation of the aluminum profiles, and then moving them into the electrophoresis tank driven by the crane to achieve synchronous electrophoresis of the multiple sections of aluminum profiles. However, in actual operation, since the electrophoresis tanks are mostly fixedly installed, the relative movement between the electrophoresis liquid inside the electrophoresis tank and the workpiece is small, and it is difficult to eliminate the bubbles generated by the workpiece during electrophoretic painting, resulting in uneven electrophoretic painting and easy occurrence of pinholes and other undesirable phenomena, which affects the appearance of the aluminum profile after electrophoresis and reduces the qualified rate of aluminum profile electrophoresis. Therefore, the present application provides a curtain wall aluminum profile surface processing technology to meet the needs. Summary of the invention

[0005] The purpose of the present application is to provide a surface processing technology for curtain wall aluminum profiles. By setting a lifting component, a limiting component, and a first driving component, the aluminum profile is made to reciprocate in the horizontal and vertical directions. Through this movement, the aluminum profile is vibrated in the electrophoretic tank, so that the bubbles attached to the surface of the aluminum profile are quickly separated from the aluminum profile, thereby ensuring full contact between the electrophoretic paint and the surface of the aluminum profile, ensuring the uniformity of the electrophoretic paint, reducing the probability of pinholes on the surface of the aluminum profile after electrophoresis, ensuring the appearance of the aluminum profile after electrophoresis, and improving the qualified rate of aluminum profile electrophoresis.

[0020] Preferably, the pressure roller and the sponge cover are both provided with a plurality of anti-slip grooves.

[0021] In summary, the technical effects and advantages of the present invention are as follows:

[0022] 1. The present invention has a reasonable structure. By arranging a lifting component, a limiting component and a first driving component, the aluminum profile is made to reciprocate in the horizontal and vertical directions. Through this movement, the aluminum profile is vibrated in the electrophoretic tank, and the bubbles attached to the surface of the aluminum profile are quickly separated from the aluminum profile, thereby ensuring full contact between the electrophoretic paint and the surface of the aluminum profile, ensuring the uniformity of the electrophoretic paint, reducing the probability of pinholes on the surface of the aluminum profile after electrophoresis, ensuring the appearance of the aluminum profile after electrophoresis, and improving the qualified rate of aluminum profile electrophoresis.

[0023] 2. In the present invention, by setting a lifting component, a limiting component and a first driving component, after the electrophoretic coating of the aluminum profile is completed, the aluminum profile is driven to rise by a winch, a lifting rope, a first beam, a first connecting rod, a second beam and an aluminum profile limiting clamp. During the rising process, the first limiting rod is driven to move by an electric push rod and a clamping claw. Under the limiting action of the first mounting frame on the first fixed axis, the moving first limiting rod drives the first limiting frame to rotate with the first fixed axis as the rotation center, thereby bending the lifting rope between the two groups of first rollers, and then causing the first beam, the first connecting rod, the second beam and the aluminum profile limiting clamp to drive the aluminum profile located in the electrophoretic pool to deviate in both the horizontal and vertical directions. The aluminum profile is caused to oscillate above the electrophoretic pool through the reciprocating motion of the aluminum profile in the horizontal and vertical directions, so that the liquid attached to the surface of the aluminum profile is quickly detached, thereby improving the drying speed of the aluminum profile after electrophoresis, reducing the time consumed by the aluminum profile electrophoresis process, and improving the efficiency of aluminum profile electrophoresis coating.

[0024] 3. In the present invention, by setting a cleaning component, when the second crossbeam drives the aluminum profile to rise through the aluminum profile limiting clamp, the guiding surface on the top of the second crossbeam will squeeze the sponge cover, so that the sponge cover drives the second fixed shaft to move through the pressure roller and the second fixed shaft, and the two moving second fixed shafts move away from each other to avoid the aluminum profile pipe mouth scratching the sponge cover during the rising process. The second crossbeam continues to move and gradually separates from the sponge cover. At this time, the surface of the rising aluminum profile contacts with the sponge cover and is quickly dried under the wiping and adsorption of the sponge cover. Under the elastic force of the spring, the pressure plate deforms the sponge cover with the cooperation of the aluminum profile through the second fixed shaft and the pressure roller, thereby increasing the contact surface between the sponge cover and the aluminum profile and improving the drying speed of the aluminum profile surface.

[0025] 4. In the present invention, the friction between the pressure roller and the sponge cover is increased by arranging the anti-skid grooves, and the servo motor is arranged. The servo motor drives the sponge cover to rotate under the action of the friction force through the pressure roller. The sponge cover rotated to the side of the pressure roller close to the pressing plate discharges the absorbed liquid under the squeezing action of the pressing plate, and fits with the surface of the aluminum profile again through rotation to ensure the drying effect on the surface of the aluminum profile when the sponge cover contacts with the aluminum profile. The structure is simple and easy to use. The protrusions between adjacent anti-skid grooves on the pressure roller can also improve the squeezing strength of the sponge cover that contacts with the protrusions and the pressing plate at the same time, thereby increasing the liquid removal effect of the sponge cover.

[0026] 5. In the present invention, by setting a guide plate, the liquid generated after the sponge cover is stripped of liquid can be guided by the guide plate to fall back into the electrophoresis pool, so that the electrophoresis pool can recycle and reuse the liquid, thereby improving the utilization efficiency of the electrophoresis liquid. At the same time, by setting the position of the guide plate and the electrophoresis pool, the sputtering range falling back into the electrophoresis pool is also reduced, thereby avoiding the electrophoresis liquid from polluting the external environment of the electrophoresis pool.

[0027] 6. In the present invention, by setting a guiding component, when the aluminum profile falls with the second cross beam under the action of the aluminum profile limiting clamp, the fixing frame also falls with the second cross beam, and the falling fixing frame contacts with the four second rollers through the inclined rod at the bottom, so that the second roller drives the pressure plate, the second fixed shaft, the pressure roller and the sponge cover to move through the elastic lifting and shrinking rod, and the two moving sponge covers move away from each other to prevent the aluminum profile pipe mouth from scratching the surface of the sponge cover during the falling process of the aluminum profile, thereby affecting the service life of the sponge cover. By setting a vertical rod, the two sponge covers can be kept separated during the descent of the aluminum profile. When the aluminum profile is completely immersed in the electric swimming pool, the pressure plate drives the elastic lifting and shrinking rod to reset under the elastic force of the spring.

[0028] 7. In the present invention, by arranging the ball head cover, the ball and the guide plate, when the aluminum profile after electrophoresis rises, the ball contacts with the guide plate, generates rolling friction with the guide plate, and drives the elastic lifting rod to shrink through the ball head cover under the guidance of the guide plate, so as to avoid the rising inclined rod from interfering with the second roller so that the elastic lifting rod drives the sponge cover to move through the pressure plate, the second fixed shaft and the pressure roller, so that the two sponge covers are separated from each other, and the aluminum profile cannot be dried during the rising process, thereby ensuring the normal use of the sponge cover during the rising process of the aluminum profile.

[0045] When the above steps are adopted to manufacture the curtain wall aluminum profile, it specifically involves the surface processing equipment of the curtain wall aluminum profile. When the above steps are adopted to manufacture the curtain wall aluminum profile, it specifically involves the surface processing equipment of the curtain wall aluminum profile, including a crane 1, an electrophoretic tank 2, and a lifting component 3 installed on the crane 1. The lifting component 3 includes two winches installed on the crane 1. The winch includes a lifting rope. The ends of the two lifting ropes are connected to the same limiting component 4. The limiting component 4 is used to limit the aluminum profile to be electrophoresed. The limiting component 4 is equipped with a first driving component 5 for moving the limiting component 4 by changing the shape of the lifting rope. The electrophoretic tank 2 is equipped with a cleaning component 6 for quickly removing liquid on the surface of the aluminum profile after electrophoresis. The limiting component 4 and the cleaning component 6 are equipped with a guiding component 7. Before the aluminum profile enters the electrophoretic tank 2, the limiting component 4 drives the cleaning component 6 to move through the guiding component 7 to avoid contact between the cleaning component 6 and the aluminum profile to be processed; the limiting component 4 includes the same first beam 8 fixedly connected to the ends of the two lifting ropes. The first driving component 5 Component 5 includes a first mounting frame 11 fixedly connected to the first beam 8, a first fixed shaft 12 is rotatably sleeved on the first mounting frame 11, an electric push rod 13 is fixedly connected to the first mounting frame 11, a claw 14 is fixedly connected to the output end of the electric push rod 13, both ends of the first fixed shaft 12 are fixedly connected to first limit frames 16, two first limit frames 16 are rotatably connected to the same first limit rod 15, the claw 14 is sleeved with the first limit rod 15, two groups of first rollers 17 are rotatably sleeved on the first limit frame 16, each group of first rollers 17 includes a plurality of first rollers 17, and two first rollers 17 can be set to reduce manufacturing costs. The first roller 17 is in contact with the suspension rope. The limiting component 4 also includes a plurality of first connecting rods 9 fixedly connected to the bottom of the first beam 8, and one end of the plurality of first connecting rods 9 away from the first beam 8 is fixedly connected to the same second beam 10, and two guide surfaces are provided on the top of the second beam 10, and a plurality of aluminum profile limiting clamps are installed on the second beam 10.

[0046] By setting the traveling crane 1, the electrostatic pool 2, the lifting component 3, and the limiting component 4, after the aluminum profile is installed on the second crossbeam 10 by the aluminum profile limiting fixture, the traveling crane 1, the lifting component 3, the first crossbeam 8, the first connecting rod 9, the second crossbeam 10, and the aluminum profile limiting fixture drive the aluminum profile to move into the electrostatic pool 2, at this time, the electric push rod 13 is started, and the electric push rod 13 drives the first limiting rod 15 to move through the claw 14. Under the limiting effect of the first mounting frame 11 on the first fixed shaft 12, the moving first limiting rod 15 drives the first limiting frame 16 to rotate with the first fixed shaft 12 as the rotation center, from The suspension rope between the two groups of first rollers 17 is bent, so that the first crossbeam 8, the first connecting rod 9, the second crossbeam 10, and the aluminum profile limiting clamp drive the aluminum profile in the electrophoretic pool 2 to deviate in the horizontal and vertical directions. The aluminum profile is vibrated in the electrophoretic pool 2 through the reciprocating motion of the aluminum profile in the horizontal and vertical directions, so that the bubbles attached to the surface of the aluminum profile are quickly separated from the aluminum profile, thereby ensuring full contact between the electrophoretic paint and the surface of the aluminum profile, ensuring the uniformity of the electrophoretic paint, reducing the probability of pinholes on the surface of the aluminum profile after electrophoresis, ensuring the appearance of the aluminum profile after electrophoresis, and improving the qualified rate of aluminum profile electrophoresis.

[0047] By setting the lifting component 3, the limiting component 4, and the first driving component 5, after the electrophoretic coating of the aluminum profile is completed, the aluminum profile is driven to rise by the winch, the suspension rope, the first crossbeam 8, the first connecting rod 9, the second crossbeam 10, and the aluminum profile limiting fixture. During the rising process, the first limiting rod 15 is driven to move by the electric push rod 13 and the claw 14. Under the limiting effect of the first mounting frame 11 on the first fixed shaft 12, the moving first limiting rod 15 drives the first limiting frame 16 to rotate with the first fixed shaft 12 as the rotation center. The aluminum profile 2 is moved to bend the suspension rope between the two groups of first rollers 17, thereby causing the first crossbeam 8, the first connecting rod 9, the second crossbeam 10, and the aluminum profile limiting clamp to drive the aluminum profile in the electrophoresis pool 2 to deviate in the horizontal and vertical directions. The aluminum profile is vibrated above the electrophoresis pool 2 through the reciprocating motion of the aluminum profile in the horizontal and vertical directions, so that the liquid attached to the surface of the aluminum profile is quickly separated, thereby increasing the drying speed of the aluminum profile after electrophoresis, reducing the time consumed in the aluminum profile electrophoresis process, and improving the efficiency of aluminum profile electrophoresis coating.

[0048] like Figure 5 , Figure 6As shown, the cleaning component 6 includes two first support plates 18 fixedly connected to the electrothermal pool 2, a plurality of first slide bars 19 are fixedly and slidably sleeved on the first support plates 18, and a plurality of first slide bars 19 are fixedly connected to the same pressing plate 20 at one end away from the first support plates 18, a spring 21 is sleeved on the first slide bar 19, and the two ends of the spring 21 respectively contact the first support plates 18 and the pressing plate 20, a servo motor 23 and a plurality of second fixed shafts 22 are fixedly connected to the pressing plate 20, and the second fixed shafts 22 can be set to two, and the output ends of the second fixed shafts 22 and the servo motor 23 are both rotatably sleeved with a pressure roller 24, and a plurality of pressure rollers 24 on the same side are sleeved with the same sponge cover 32, and a plurality of anti-slip grooves are provided on the pressure roller 24 and the sponge cover 32, and the spacing between the two sponge covers 32 on one side close to each other is greater than the diameter of the first connecting rod 9. A first limiting cover 33 is fixedly connected to the pressing plate 20, and the first limiting cover 33 is rotatably sleeved with the output end of the servo motor 23.

[0049] By setting the cleaning component 6, when the second crossbeam 10 drives the aluminum profile to rise through the aluminum profile limiting clamp, the guiding surface on the top of the second crossbeam 10 will squeeze the sponge cover 32, so that the sponge cover 32 drives the second fixed shaft 22 to move through the pressure roller 24 and the second fixed shaft 22, and the two moving second fixed shafts 22 move away from each other to avoid the aluminum profile pipe mouth from scratching the sponge cover 32 during the rising process. The second crossbeam 10 continues to move and gradually separates from the sponge cover 32. At this time, the surface of the rising aluminum profile contacts with the sponge cover 32 and is quickly dried under the wiping and adsorption of the sponge cover 32. Under the elastic force of the spring 21, the pressure plate 20 deforms the sponge cover 32 with the cooperation of the aluminum profile through the second fixed shaft 22 and the pressure roller 24, thereby increasing the contact area between the sponge cover 32 and the aluminum profile and increasing the drying speed of the aluminum profile surface. At the same time, this function cooperates with the first driving component 5 to further increase the drying speed of the aluminum profile surface.

[0050] By setting the anti-skid groove, the friction between the pressure roller 24 and the sponge cover 32 is increased. By setting the servo motor 23, the servo motor 23 drives the sponge cover 32 to rotate under the action of the friction force through the pressure roller 24. The sponge cover 32 rotates to the side of the pressure roller 24 close to the pressing plate 20 and discharges the absorbed liquid under the squeezing action of the pressing plate 20, and fits with the surface of the aluminum profile again through rotation to ensure the drying effect on the surface of the aluminum profile when the sponge cover 32 contacts the aluminum profile. The structure is simple and easy to use. The protrusions between adjacent anti-skid grooves on the pressure roller 24 can also improve the squeezing strength of the sponge cover 32 that contacts the protrusions and the pressing plate 20 at the same time, thereby increasing the deliquescence effect of the sponge cover 32.

[0051] like Figure 5 , Figure 7As shown, the bottom of the two pressure plates 20 is provided with a guide plate that bends downward and extends to the electrophoresis pool 2. The ends of the two guide plates are close to each other, and the bottom of the guide plate is flush with the top of the electrophoresis pool 2. By setting the guide plate, the liquid generated after the sponge sleeve 32 is dehydrated is guided by the guide plate to fall back into the electrophoresis pool 2, so that the electrophoresis pool 2 can recycle and reuse the liquid, thereby improving the utilization efficiency of the electrophoresis liquid. At the same time, through the position setting of the guide plate and the electrophoresis pool 2, the sputtering range falling back into the electrophoresis pool 2 is also reduced, thereby preventing the electrophoresis liquid from polluting the external environment of the electrophoresis pool 2.

[0052] like Figure 3 , Figure 6 As shown, the guide component 7 includes two elastic lifting rods 25 fixedly connected to the pressure plate 20, the two elastic lifting rods 25 are symmetrical to each other, the telescopic section of the elastic lifting rod 25 is rotatably sleeved with a second roller 26, the end of the telescopic section of the elastic lifting rod 25 is fixedly connected with a ball head sleeve 27, and a ball 28 is rotatably sleeved in the ball head sleeve 27. The guide component 7 also includes two fixed frames 29 fixedly connected to the first crossbeam 8, the fixed frames 29 include two symmetrical vertical rods 34 and two groups of inclined rods 30, each group of inclined rods 30 includes two inclined rods 30, the two inclined rods 30 located on the same side of the fixed frames 29 are symmetrical to each other, the inclined rods 30 are fixedly connected with a guide plate 31, and the two vertical rods 34 are located on the side away from the two second rollers 26.

[0053] By setting the guide component 7, when the aluminum profile falls with the second crossbeam 10 under the action of the aluminum profile limiting clamp, the fixing frame 29 also falls with the second crossbeam 10, and the falling fixing frame 29 contacts the four second rollers 26 through the inclined rod 30 at the bottom, so that the second roller 26 drives the pressure plate 20, the second fixed shaft 22, the pressure roller 24, and the sponge cover 32 to move through the elastic lifting and contraction rod 25, and the two moving sponge covers 32 move away from each other to prevent the aluminum profile pipe mouth from scratching the surface of the sponge cover 32 during the falling process of the aluminum profile, thereby affecting the service life of the sponge cover 32. By setting the vertical rod 34, the two sponge covers 32 remain separated during the descent of the aluminum profile. When the aluminum profile is completely immersed in the electric swimming pool 2, the pressure plate 20 drives the elastic lifting and contraction rod 25 to reset under the elastic force of the spring 21.

[0054] By setting the ball head cover 27, the ball 28 and the guide plate 31, when the aluminum profile after electrophoresis rises, the ball 28 contacts with the guide plate 31, generates rolling friction with the guide plate 31, and drives the elastic lifting rod 25 to shrink through the ball head cover 27 under the guidance of the guide plate 31, so as to prevent the rising inclined rod 30 from colliding with the second roller 26 so that the elastic lifting rod 25 drives the sponge cover 32 to move through the pressure plate 20, the second fixed shaft 22 and the pressure roller 24, so that the two sponge covers 32 are separated from each other, and the aluminum profile cannot be dried during the rising process, thereby ensuring the normal use of the sponge cover 32 during the rising process of the aluminum profile.

[0055] like Figure 2 As shown, the two fixing frames 29 are located on both sides of the second cross beam 10, and the distance between the two fixing frames 29 is greater than the length of the electrophoresis pool 2, so as to prevent the fixing frames 29 from moving into the electrophoresis pool 2 during the falling process of the second cross beam 10, resulting in unnecessary loss of the electrophoresis fluid in the electrophoresis pool 2 and increasing the electrophoresis cost.

[0056] Working principle of the present invention:

[0057] By setting a traveling crane, an electric pool, a lifting component, and a limiting component, the aluminum profile is installed on the second crossbeam through the aluminum profile limiting fixture, and then the aluminum profile is driven to move into the electric pool through the traveling crane, the lifting component, the first crossbeam, the first connecting rod, the second crossbeam, and the aluminum profile limiting fixture. At this time, the electric push rod is started, and the electric push rod drives the first limiting rod to move through the claw. Under the limiting effect of the first mounting frame on the first fixed axis, the moving first limiting rod drives the first limiting frame to rotate with the first fixed axis as the rotation center, so that the aluminum profile between the two sets of first rollers The suspension rope is bent, so that the first crossbeam, the first connecting rod, the second crossbeam, and the aluminum profile limiting clamp drive the aluminum profile in the electrophoretic pool to deviate in the horizontal and vertical directions. The aluminum profile is vibrated in the electrophoretic pool through the horizontal and vertical reciprocating motion of the aluminum profile, so that the bubbles attached to the surface of the aluminum profile are quickly separated from the aluminum profile, thereby ensuring full contact between the electrophoretic paint and the surface of the aluminum profile, ensuring the uniformity of the electrophoretic paint, reducing the probability of pinholes on the surface of the aluminum profile after electrophoresis, ensuring the appearance of the aluminum profile after electrophoresis, and improving the qualified rate of aluminum profile electrophoresis.

[0058] By setting a lifting component, a limiting component and a first driving component, after the electrophoretic coating of the aluminum profile is completed, the aluminum profile is driven to rise by the winch, the lifting rope, the first beam, the first connecting rod, the second beam and the aluminum profile limiting clamp. During the rising process, the first limiting rod is driven to move by the electric push rod and the claw. Under the limiting effect of the first mounting frame on the first fixed axis, the moving first limiting rod drives the first limiting frame to rotate with the first fixed axis as the rotation center, so that the lifting rope between the two groups of first rollers is bent, and then the first beam, the first connecting rod, the second beam and the aluminum profile limiting clamp drive the aluminum profile in the electrophoretic pool to deviate in the horizontal and vertical directions. The aluminum profile is vibrated above the electrophoretic pool through the reciprocating motion of the aluminum profile in the horizontal and vertical directions, so that the liquid attached to the surface of the aluminum profile is quickly detached, thereby improving the drying speed of the aluminum profile after electrophoresis, reducing the time spent in the aluminum profile electrophoresis process, and improving the efficiency of aluminum profile electrophoresis coating.

[0059] By setting a cleaning component, when the second crossbeam drives the aluminum profile to rise through the aluminum profile limiting clamp, the guiding surface on the top of the second crossbeam will squeeze the sponge cover, so that the sponge cover drives the second fixed shaft to move through the pressure roller and the second fixed shaft, and the two moving second fixed shafts move away from each other to avoid the aluminum profile pipe mouth scratching the sponge cover during the rising process. The second crossbeam continues to move and gradually separates from the sponge cover. At this time, the surface of the rising aluminum profile contacts with the sponge cover and is quickly dried under the wiping and adsorption of the sponge cover. Under the elastic force of the spring, the pressure plate deforms the sponge cover with the cooperation of the aluminum profile through the second fixed shaft and the pressure roller, thereby increasing the contact surface between the sponge cover and the aluminum profile and improving the drying speed of the aluminum profile surface.

[0060] By arranging the anti-skid groove, the friction between the pressure roller and the sponge sleeve is increased. By arranging the servo motor, the servo motor drives the sponge sleeve to rotate under the action of the friction force through the pressure roller. The sponge sleeve that rotates to the side of the pressure roller close to the pressure plate discharges the absorbed liquid under the squeezing action of the pressure plate, and fits with the surface of the aluminum profile again through rotation to ensure the drying effect on the surface of the aluminum profile when the sponge sleeve contacts the aluminum profile. The structure is simple and easy to use. Through the protrusions between adjacent anti-skid grooves on the pressure roller, the squeezing strength of the sponge sleeve that contacts the protrusions and the pressure plate at the same time can also be improved, thereby increasing the liquid removal effect of the sponge sleeve.

[0061] By setting the guide plate, the liquid generated after the sponge sleeve is stripped of liquid can be guided by the guide plate to fall back into the electrophoresis pool, so that the electrophoresis pool can recycle and reuse the liquid, thereby improving the utilization efficiency of the electrophoresis liquid. At the same time, by setting the position of the guide plate and the electrophoresis pool, the splashing range falling back into the electrophoresis pool is also reduced, thereby preventing the electrophoresis liquid from polluting the external environment of the electrophoresis pool.

[0062] By setting the guiding component, when the aluminum profile falls with the second cross beam under the action of the aluminum profile limiting clamp, the fixing frame also falls with the second cross beam, and the falling fixing frame contacts with the four second rollers through the inclined rod at the bottom, so that the second roller drives the pressure plate, the second fixed shaft, the pressure roller and the sponge cover to move through the elastic lifting and contraction rod, and the two moving sponge covers move away from each other to prevent the aluminum profile pipe mouth from scratching the surface of the sponge cover during the falling process of the aluminum profile, thereby affecting the service life of the sponge cover; by setting the vertical rod, the two sponge covers can continue to be separated during the descent of the aluminum profile, and when the aluminum profile is completely immersed in the electric swimming pool, the pressure plate drives the elastic lifting and contraction rod to reset under the elastic force of the spring.

[0063] By arranging the ball head sleeve, the ball bearing and the guide plate, when the aluminum profile after electrophoresis rises, the ball bearing contacts with the guide plate, generates rolling friction with the guide plate, and drives the elastic lifting and shrinking rod to shrink through the ball head sleeve under the guidance of the guide plate, so as to avoid the rising inclined rod from colliding with the second roller so that the elastic lifting and shrinking rod drives the sponge sleeve to move through the pressure plate, the second fixed shaft and the pressure roller, so that the two sponge sleeves move away from each other, thereby preventing the aluminum profile from being dried during the rising process, thereby ensuring the normal use of the sponge sleeve during the rising process of the aluminum profile.
