Description

Technical Field

[0001] The invention relates to the technical field of an anodizing production line for die-casting aluminum alloys, in particular to an anodizing production line for die-casting aluminum alloys. Background Art

[0002] Aluminum alloy profiles are the most widely used type of non-ferrous metal structural materials in industry. Aluminum alloy profiles have been widely used in solar photovoltaic power generation, aviation, aerospace, automobiles, and machinery manufacturing. When existing aluminum alloy profiles are oxidized, electrolytic oxidation is often used to oxidize aluminum alloy profiles.

[0003] Anodizing of aluminum alloys is an electrochemical surface treatment technology. By placing the aluminum alloy as the anode in the electrolyte, an electric current is used to form a layer of aluminum oxide film on its surface. This oxide film has protective, decorative and other functional properties, and can significantly improve the corrosion resistance, wear resistance and hardness of the aluminum alloy.

[0004] When the die-cast aluminum alloy anodizing production line in the prior art oxidizes batches of die-cast aluminum alloy, a large-scale circulating reciprocating telescopic mechanism is used to clamp the die-cast aluminum alloy. This results in a large space required for the installation and use of the overall production line, and it may also be necessary to renovate the factory building where it is placed. The overall engineering workload is large, and subsequent maintenance is relatively troublesome. After the subsequent oxidation is completed, it needs to be transferred to a water tank for cleaning. In the process of the control device driving multiple aluminum alloy profiles to move upward and transfer to the water tank, part of the oxidation liquid will be driven to leave the oxidation tank together, and part of the oxidation liquid will be splashed into the water tank, which increases the composition of the oxidation liquid inside the water tank, reduces the cleaning efficiency of the aluminum alloy profiles, and further leads to a decrease in the oxidation treatment efficiency of the aluminum alloy profiles. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an anodizing production line for die-cast aluminum alloys to solve the technical problems that the space required for the installation and use of the overall production line is large, the overall engineering workload is large, the subsequent maintenance is relatively troublesome, and during the cleaning process, part of the oxidizing liquid will be driven out of the oxidation tank, thereby causing part of the oxidizing liquid to splash into the inside of the water tank and reduce the cleaning efficiency of the aluminum alloy profiles.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anodizing production line for die-cast aluminum alloy, comprising a clamping mechanism and an oxidation bin, wherein an electric guide rail matching therewith is arranged at the top of the clamping mechanism, the clamping mechanism comprises a limit plate, a limit cavity, a limit block, a rotating shaft and a torsion spring, the limit plate is movably connected to the bottom end of the electric guide rail, the limit cavity is arranged inside the limit plate, the limit block is movably connected to the limit plate through the rotating shaft, a torsion spring located on the outside of the rotating shaft is fixed between the limit plate and the limit block, a shifting mechanism is movably connected inside the oxidation bin, the shifting mechanism comprises a resist plate, a movable base, a movable resist plate, a fixed seat, a slide plate, a first spring and a limit rod, the resist plate is fixed at one end of the fixed seat, the movable base and the fixed seat are elastically connected by a first spring arranged on the outside of the limit rod arranged at the bottom end of the movable base, and the movable resist plate cooperates with the sliding cavity opened inside the bottom end of the fixed seat through the slide plate arranged at the bottom end.

[0007] By adopting the above technical solution, when in use, the power is turned on, and the die-cast aluminum alloy plate to be anodized is placed into the clamping mechanism provided at the bottom end of the electric guide rail by an external worker through a tool;

[0008] First, the limit block set inside the clamping mechanism will show an angle change due to the extrusion of the die-cast aluminum alloy plate, and the staff can easily push the die-cast aluminum alloy plate into the center of the two sets of clamping mechanisms. When the die-cast aluminum alloy plate is pushed, the limit block will be reset under the elastic potential energy of the torsion spring due to the action of the torsion spring. At this time, the angle of the limit block will no longer change, and because of the structural characteristics of the limit block, the limit block will not change its angle due to the gravity of the die-cast aluminum alloy plate, so as to achieve the limiting and fixing effect of the die-cast aluminum alloy plate, so as to facilitate the movement of the die-cast aluminum alloy plate inside the clamping mechanism through the electric guide rail, so as to complete the operation of the early oxidation of the die-cast aluminum alloy;

[0009] Then, the clamping mechanism is moved to the top of the oxidation bin by the electric guide rail, and the motor arranged at the bottom of the oxidation bin is started. When the motor is started, the rotating rod arranged at its output end is driven to rotate. When the rotating rod rotates, the first bevel gear set and the second bevel gear set arranged at the outer side thereof are driven to rotate synchronously.

[0010] When the first bevel gear set rotates, it will drive the first screw rod to rotate synchronously. When the first screw rod rotates, it will drive the first fixed plate threadedly connected to its outer side to move upward as a whole. Because the first fixed plate is fixed to one end of the fixed seat, it will drive the fixed seat to move upward synchronously. When the fixed seat moves upward, it will drive the overall shifting mechanism to move toward the top. When it moves to a suitable position, the abutment plates respectively arranged at both ends of the shifting mechanism will abut against the two ends of the die-cast aluminum alloy plate, and then when it moves upward again, the moving abutment plate arranged inside the shifting mechanism will slowly move upward, and while moving, it will slowly squeeze the limit blocks arranged inside the two sets of clamping mechanisms, and through squeezing, the limit blocks will change their angles with the rotating shaft as the axis. When the angle of the limit block changes, the die-cast aluminum alloy plate will be pushed upward for a distance.

[0011] When the stop plate is moved and the limit block is squeezed to a critical value, the die-cast aluminum alloy plate clamped in the clamping mechanism can fall off. At this time, the movable base arranged in the shifting mechanism moves to a suitable safety distance from the die-cast aluminum alloy plate to prevent the die-cast aluminum alloy from being damaged while falling. The impact force generated after the fall will be buffered by the first spring arranged on the outer side of the limit rod between the movable base and the fixed seat to prevent the die-cast aluminum alloy from shaking or swaying.

[0012] When the second bevel gear set rotates synchronously, it will drive the second screw to rotate synchronously, so that the screw moving block threadedly connected to the outer side of the second screw will drive the mobile cleaning plate to move upward synchronously with the shifting mechanism, and at this time, the multiple cleaning fans will not start;

[0013] Then, the motor is reversed by electrically controlling it. When the motor reverses, the first screw rod and the second screw rod will also reverse synchronously. When the first screw rod reverses, it will drive the shift mechanism to move downward. When the shift mechanism moves downward to the inside of the oxidation bin, the external control device will energize the cathode plate located inside the oxidation bin supplied by the cathode power supply block, and the anode rod supplied by the anode power supply block inside the oxidation bin will be powered synchronously, so that the die-cast aluminum alloy fixed inside the shift mechanism can be anodized.

[0014] During the anodizing process, the motor will still rotate in the reverse direction, so that the first fixing plate arranged at the bottom end of the fixing seat will slowly move to the bottom end of the first screw rod, and the fixed conical screw rod will be in a slipping state between the conical screw rod and the first fixing plate, thereby causing the first fixing plate and the fixing seat fixed at the top thereof to move downward rapidly, and because of the fourth spring arranged on the outside of the conical screw rod and the third spring arranged on the outside of the multiple groups of anode rods, the fast falling will be ensured while repeatedly shaking due to the elasticity of the springs, thereby increasing the contact area between the die-cast aluminum alloy plate and the electrolyte in the oxidation bin, thereby improving the efficiency of anodizing of the die-cast aluminum alloy plate;

[0015] When the second screw rod rotates in the opposite direction, it will drive the screw rod moving block threadedly connected to the outer side of the second screw rod to move downward synchronously. Because the bottom end of the second screw rod is smooth and has no threads, a part of the screw rod moving block will still be threadedly connected to it when it moves to the bottom end, so the screw rod moving block will shake when moving downward. At this time, multiple sets of second springs are used to buffer the shaking of the screw rod moving block when it moves downward, so as to prevent it from moving downward excessively and causing the overall mechanism to jam.

[0016] When the anodizing is completed, the motor output end rotates forward again, so that the shift mechanism moves upward. However, at this time, the shift mechanism causes the movable base to move downward as a whole due to the weight of the die-cast aluminum alloy. When the movable base moves downward as a whole, it drives the first toothed plate set at one end thereof to move downward, and the first gear is rotated by the first toothed plate, so that the first gear, through the round rod fixed at one end thereof, synchronously rotates the second gear located at the other end of the fixed seat;

[0017] When the second gear rotates, it drives the movable plate meshing with its gear on the outside to move, and a sliding plate matched with the fixed seat is also provided at the bottom of the movable plate to prevent the movable plate from being dislocated while moving, so that the movable plate moves outward, and the movable plate located at the other end of the fixed seat also performs the above steps synchronously;

[0018] Therefore, when the shifting mechanism fits with the clamping mechanism, the limit block will be pushed to change its angle through the die-cast aluminum alloy plate, and the moving plate will produce a distance change relative to the outside, so the limit block will not be squeezed during the shifting mechanism, and the die-cast aluminum alloy will be slowly pushed into the middle of the two sets of clamping mechanisms through the overall rise of the shifting mechanism. At this time, because the movable base is convex, there is enough space to cooperate with the torsion spring inside the limit block to reset the limit block, thereby realizing limit fixation;

[0019] At this time, because the positive rotation of the motor output end can also drive the second screw to rotate through the second bevel gear set, it will drive the screw moving block on the outside of the oxidation bin that is threadedly connected to the second screw to move upward synchronously, and the cleaning moving plate fixed by the screw moving block will also move upward synchronously. When the shifting mechanism reaches the appropriate position, the cleaning moving plate will also reach the predetermined position. At this time, multiple sets of cleaning fans arranged on the outside of the cleaning moving plate will start. The cleaning fan generates airflow through the rotation of the blades. This airflow can accelerate the flow speed of the air, effectively blow off or disperse most of the residual electrolyte on the die-cast aluminum alloy plate, and clean the electrolyte brought out after the anodizing process of the die-cast aluminum alloy plate, so as to prevent the die-cast aluminum alloy plate from carrying more residual electrolyte into the subsequent cleaning water washing tank;

[0020] Specifically, the multiple groups of anode rods play a role in limiting and also play a role in cooperating with the die-cast aluminum alloy plate for anodizing, wherein the multiple groups of rubber limit blocks arranged at one end of the abutment plate can limit and fix the die-cast aluminum alloy and can reduce the contact area between the die-cast aluminum alloy and the two groups of abutment plates inside the shifting mechanism, increase the contact area between the die-cast aluminum alloy and the electrolyte inside the oxidation bin, and increase the efficiency of anodizing of the die-cast aluminum alloy;

[0021] Through the above structure, when the die-cast aluminum alloy is anodized, the installation of the overall production line can be more convenient, the overall engineering workload is small, and the subsequent maintenance is more convenient. When it needs to be transferred to a water tank for cleaning after the subsequent oxidation is completed, the residual electrolyte on the outside of the die-cast aluminum alloy can be cleaned through the cleaning mechanism to prevent the increase of the components of the oxidizing liquid inside the subsequent water tank, thereby ensuring the cleaning efficiency of the subsequent cleaning tank for the aluminum alloy profile, thereby improving the oxidation treatment efficiency of the aluminum alloy profile.

[0022] Furthermore, a motor is arranged inside the oxidation bin, a rotating rod is arranged at the output end of the motor, a first bevel gear set is arranged outside the rotating rod, and the conical screw rod is connected through the first bevel gear set for transmission, a plurality of groups of anode rods are arranged inside the oxidation bin, a spring plate is arranged on the outside, and the spring plate, the anode rod and the conical screw rod are elastically connected through a fourth spring located on the outside of the conical screw rod and a third spring located on the anode rod.

[0023] By adopting the above technical solution, the rotating rod is driven by the output end of the motor, and the power source is provided by the first bevel gear set and the second bevel gear set to rotate the first screw rod and the second screw rod, thereby ensuring that the shifting mechanism and the cleaning mechanism can move along a fixed direction.

[0024] Furthermore, the shifting mechanism also includes a first screw rod, a rubber limit block, a first tooth plate, a first gear and a second gear. The first screw rod is fixed to the top end of the conical screw rod, the multiple groups of rubber limit blocks are fixed to one end of the support plate, the first tooth plate is fixed to one end of the movable support plate, the outer side of the first gear is meshed at one end of the first tooth plate, and the outer side of the second gear is meshed at one end of the movable support plate.

[0025] By adopting the above technical solution, the first screw rod, rubber limit block, first tooth plate, first gear and second gear arranged inside the shifting mechanism can ensure that when the movable base moves downward due to the weight of the die-cast aluminum alloy, the moving force can be transmitted to the movable plate arranged on the outside of the fixed seat to control the movement of the movable plate.

[0026] Furthermore, a cleaning mechanism is provided on the outside of the oxidation bin, and the cleaning mechanism includes a cleaning movable plate, a fixed block, a cleaning fan, a second screw, a screw movable block and an engaging slide. The cleaning movable plate and multiple groups of cleaning fans are fixed by multiple groups of fixed blocks and bolts, and a screw movable block threadedly connected to the second screw is provided on one side of the cleaning movable plate. The cleaning movable plate is limited by sliding cavities opened at both ends thereof and multiple groups of engaging slides fixed on the outside of the oxidation bin.

[0027] By adopting the above technical scheme, after the anodic oxidation of the die-cast aluminum alloy in the oxidation chamber is completed, the cleaning mechanism can be used to clean the residual electrolyte on the surface of the die-cast aluminum alloy, so as to prevent the die-cast aluminum alloy from bringing the residual electrolyte into the next set of cleaning tanks, thereby affecting the cleaning effect of the subsequent cleaning tanks.

[0028] Furthermore, a cathode plate is provided at the top of the oxidation bin, a second fixed plate cooperating with the anode rod and the first screw rod is provided at the top of the oxidation bin, a cathode power supply block connected to the cathode plate is provided at the top of the cathode plate, and an anode power supply block connected to the anode rod is provided at the bottom of the anode rod.

[0029] By adopting the above technical solution, the cathode plate is used to ensure that the electrolyte inside the oxidation chamber can be energized through the cathode plate, so as to cooperate with the subsequent anodic oxidation of the die-cast aluminum alloy.

[0030] Furthermore, the cleaning mechanism also includes a second spring, and the screw moving block and the oxidation bin are elastically connected via a plurality of groups of second springs.

[0031] By adopting the above technical solution, the second spring is used to make the screw rod moving block shake downward after slipping, and at the same time, the second spring causes shaking, thereby offsetting the force of the screw rod moving block rotating downward.

[0032] Furthermore, the material of the abutment plate is insulating rubber, and a cavity cooperating with the limiting rod is arranged inside the fixing seat.

[0033] By adopting the above technical solution, the material of the limit block is insulating rubber, which can ensure that the subsequent die-cast aluminum alloy will not be deformed during the anodizing process, resulting in poor subsequent limiting and fixing effects, and the cavity opened inside the fixing seat can ensure flexible movement of the limit rod.

[0034] Furthermore, a plurality of first fixing plates arranged outside the anode rod and the first screw rod are fixed on the top of the fixing seat, and the rotating rod and the tapered screw rod are connected in transmission via a first bevel gear set.

[0035] By adopting the above technical solution, the movement of the fixing seat is ensured by the first fixing plate, and no shaking or dislocation occurs during the movement, and then the first bevel gear set is used to enable transmission between the rotating rod and the tapered screw.

[0036] Furthermore, the clamping mechanism also includes a roller, and the roller is movably connected to one end inside the limiting block, and a bearing is provided between the limiting block and the roller.

[0037] By adopting the above technical solution, the roller can ensure that the die-cast aluminum alloy will not be damaged due to the corners of the limit block during the subsequent movement or clamping of the die-cast aluminum alloy.

[0038] Furthermore, the rotating rod and the second screw rod are connected in transmission via a second bevel gear set, the oxidation bin is provided with multiple sets of support seats, and the electric guide rail is fixed by multiple sets of fixing bolts.

[0039] By adopting the above technical solution, the stability of the oxidation bin during subsequent use is ensured by the support seat to ensure subsequent work efficiency, and the transmission between the rotating rod and the second screw rod is ensured by the second bevel gear set.

[0040] In summary, the present invention mainly has the following beneficial effects: the present invention clamps and fixes the die-cast aluminum alloy plate that needs to be anodized outside through the cooperation of the limit plate, the limit block, the torsion spring and the rotating shaft arranged inside the clamping mechanism, so as to facilitate the orderly movement of the die-cast aluminum alloy plate, and then the motor is started to drive the rotating rod so that the first screw rod fixed at the top of the tapered screw rod also rotates synchronously. While the first screw rod rotates, it drives the shifting mechanism to move upward, and through the cooperation with the clamping mechanism, the die-cast aluminum alloy belt falls into the inside of the shifting mechanism. The subsequent shifting mechanism is moved to allow the die-cast aluminum alloy to enter the oxidation bin and be completely immersed in the electrolyte. The anode rod inside the shifting mechanism and the cathode plate located inside the oxidation bin are energized to oxidize the die-cast aluminum alloy. After the oxidation is completed, the second screw is driven by a motor to rotate so that the cleaning moving plate drives multiple groups of cleaning fans fixed on the outside to clean and dry the surface of the anodized aluminum alloy, so as to prevent excessive electrolyte from entering the subsequent water washing tank during the subsequent water washing process, thereby affecting the subsequent water washing effect.

Firstly, the limit block 103 arranged inside the clamping mechanism 1 will show an angle change due to the extrusion of the die-cast aluminum alloy plate, and the staff can easily push the die-cast aluminum alloy plate into the two sets of clamping mechanisms. 1, when the die-cast aluminum alloy plate is pushed forward, the limit block 103 will be reset under the elastic potential energy of the torsion spring 106 due to the action of the torsion spring 106, and the angle of the limit block 103 will no longer change, and because of the structural characteristics of the limit block 103, the limit block 103 will not change its angle due to the gravity of the die-cast aluminum alloy plate, so as to achieve the limiting and fixing effect of the die-cast aluminum alloy plate, so as to facilitate the movement of the die-cast aluminum alloy plate inside the clamping mechanism 1 through the electric guide rail 6, so as to complete the operation of the early oxidation of the die-cast aluminum alloy;

[0060] Exemplarily, a torsion spring 106 located on the outside of the rotating shaft 104 is fixed between the limit plate 101 and the limit block 103, and a shift mechanism 2 is movably connected inside the oxidation bin 4.

Then, when it moves upward again, the movable abutment plates 205 arranged inside the shifting mechanism 2 will move upward slowly, and while moving, they will slowly squeeze the limit blocks 103 arranged inside the two groups of clamping mechanisms 1, and through squeezing, the limit blocks 103 change their angles with the rotating shaft 104 as the axis. When the limit blocks 103 change their angles, the die-cast aluminum alloy plate will be pushed upward for a certain distance.

At this time, the movable base 204 arranged in the displacement mechanism 2 is moved to a suitable safety distance from the die-cast aluminum alloy plate to prevent the die-cast aluminum alloy from being damaged while falling. The impact force generated after falling will be buffered by the first spring 208 arranged on the outer side of the limit rod 209 between the movable base 204 and the fixed seat 206 to prevent the die-cast aluminum alloy from shaking or swaying.

The cleaning movable plate 301 is limited by sliding cavities opened at both ends thereof and multiple groups of snap-on slide plates 306 fixed on the outside of the oxidation bin 4. A cathode plate 8 is provided at the top of the oxidation bin 4. The pole 12 and the second fixing plate 16 matched with the first screw rod 201, wherein, when the shifting mechanism 2 is fitted with the clamping mechanism 1, the limit block is pushed to change its angle through the die-cast aluminum alloy plate, and the moving plate 205 produces a distance change relative to the outside, so the limit block 103 will not be squeezed during the shifting mechanism 2, and the die-cast aluminum alloy is slowly pushed into the middle of the two sets of clamping mechanisms 1 through the overall rise of the shifting mechanism 2. At this time, because the movable base 204 is convex, there is enough space to cooperate with the torsion spring 106 inside the limit block 103 to reset the limit block 103, thereby realizing limit fixation;

[0065] Exemplarily, a cathode power supply block 21 connected to the cathode plate 8 is provided at the top end thereof, an anode power supply block 20 connected to the anode rod 12 is provided at the bottom end thereof, the cleaning mechanism 3 further includes a second spring 307, and the screw moving block 305 is elastically connected to the oxidation bin 4 via a plurality of groups of second springs 307, the rubber limit block 203 is made of insulating rubber, a cavity matching the limit rod 209 is provided inside the fixed seat 206, a plurality of groups of first fixed plates 13 arranged outside the anode rod 12 and the first screw rod 201 are fixed at the top end of the fixed seat 206, the rotating rod 18 is connected to the tapered screw rod 15 by a first bevel gear set 17 for transmission, the clamping mechanism 1 further includes a roller 105, and the roller 105 is movably connected to one end inside the limit block 103, a bearing is provided between the limit block 103 and the roller 105, the rotating rod 18 is connected to the second screw rod 304 by a second bevel gear set 19 for transmission, The oxidation bin 4 is provided with a plurality of support seats 5, wherein at this time, because the forward rotation of the output end of the motor 9 can also drive the second screw rod 304 to rotate through the second bevel gear set 19, it will drive the screw moving block 305 threadedly connected to the second screw rod 304 on the outside of the oxidation bin 4 to move upward synchronously, and the cleaning moving plate 301 fixed by the screw moving block 305 will also move upward synchronously. When the shifting mechanism 2 arrives at the appropriate position, the cleaning moving plate 301 will also arrive at the predetermined position. At this time, the plurality of cleaning fans 303 arranged on the outside of the cleaning moving plate 301 will be started. The cleaning fan 303 generates airflow through the rotation of the blades. This airflow can accelerate the flow speed of the air, effectively blow off or disperse most of the residual electrolyte on the die-cast aluminum alloy plate, to clean the electrolyte brought out after the anodizing process of the die-cast aluminum alloy plate, and prevent the die-cast aluminum alloy plate from carrying more residual electrolyte into the subsequent cleaning water washing tank.

[0066] The working principle of the present invention is as follows: when in use, the power is turned on, and an external worker puts the die-cast aluminum alloy plate to be anodized into the clamping mechanism 1 provided at the bottom end of the electric guide rail 6 through a tool;

[0067] Firstly, the limit block 103 arranged inside the clamping mechanism 1 will show an angle change due to the extrusion of the die-cast aluminum alloy plate, and the staff can easily push the die-cast aluminum alloy plate into the center of the two sets of clamping mechanisms 1. When the die-cast aluminum alloy plate is pushed forward, the limit block 103 will be reset under the elastic potential energy of the torsion spring 106 due to the action of the torsion spring 106. At this time, the angle of the limit block 103 will no longer change, and because of the structural characteristics of the limit block 103, the limit block 103 will not change its angle due to the gravity of the die-cast aluminum alloy plate, so as to achieve the limiting and fixing effect of the die-cast aluminum alloy plate, so as to facilitate the movement of the die-cast aluminum alloy plate inside the clamping mechanism 1 through the electric guide rail 6, so as to complete the operation of the early oxidation of the die-cast aluminum alloy;

[0068] Then, the clamping mechanism 1 is moved to the top of the oxidation bin 4 by the electric guide rail 6. At this time, the motor 9 arranged at the bottom of the oxidation bin 4 is started. When the motor 9 is started, the rotating rod 18 arranged at its output end is driven to rotate. When the rotating rod 18 rotates, the first bevel gear set 17 and the second bevel gear set 19 arranged at the outer side thereof are driven to rotate synchronously.

[0069] When the first bevel gear set 17 rotates, it will drive the first screw rod 201 to rotate synchronously. When the first screw rod 201 rotates, it will drive the first fixed plate 13 threadedly connected to its outer side to move upward as a whole. Because the first fixed plate 13 is fixed to one end of the fixed seat 206, it will drive the fixed seat 206 to move upward synchronously. When the fixed seat 206 moves upward, it will drive the entire shifting mechanism 2 to move toward the top. When it moves to a suitable position, the 202 abutment plates respectively arranged at both ends of the shifting mechanism 2 will abut against the two ends of the die-cast aluminum alloy plate, and then when it moves upward again, the moving abutment plate 205 arranged inside the shifting mechanism 2 will slowly move upward, and while moving, it will slowly squeeze the limit blocks 103 arranged inside the two groups of clamping mechanisms 1, and through squeezing, the limit blocks 103 change their angles with the rotating shaft 104 as the axis. When the angle of the limit block 103 changes, the die-cast aluminum alloy plate will be pushed upward for a distance.

[0070] When the stop plate 205 is moved and the limit block 103 is squeezed to a critical value, the die-cast aluminum alloy plate clamped in the clamping mechanism 1 can fall off. At this time, the movable base 204 arranged in the displacement mechanism 2 is moved to a suitable safety distance from the die-cast aluminum alloy plate to prevent the die-cast aluminum alloy from being damaged while falling. The impact force generated after falling will be buffered by the first spring 208 arranged on the outer side of the limit rod 209 between the movable base 204 and the fixed seat 206 to prevent the die-cast aluminum alloy from shaking or swaying.

[0071] When the second bevel gear set 19 rotates synchronously, the second screw rod 304 will be driven to rotate synchronously, so that the screw rod moving block 305 threadedly connected to the outer side of the second screw rod 304 will drive the mobile cleaning plate 301 to move upward synchronously with the shifting mechanism 2, and at this time, the multiple cleaning fans 303 are not started;

[0072] Then, the motor 9 is electrically controlled to reverse. When the motor 9 reverses, the first screw rod 201 and the second screw rod 304 will also reverse synchronously. When the first screw rod 201 reverses, it will drive the shift mechanism 2 to move downward. When the shift mechanism 2 moves downward to the inside of the oxidation bin 4, the external control device will energize the cathode plate 8 located inside the oxidation bin 4 supplied by the cathode power supply block 21, and the anode rod supplied by the anode power supply block 20 inside the oxidation bin 4 will be powered synchronously, so that the die-cast aluminum alloy fixed inside the shift mechanism 2 can be anodized.

[0073] During the anodizing process, the motor 9 will still rotate in the reverse direction, so that the first fixed plate 13 arranged at the bottom end of the fixed seat 206 will slowly move to the bottom end of the first screw rod 201, and the fixed tapered screw rod 15 will be in a slipping state between the tapered screw rod 15 and the first fixed plate 13, thereby causing the first fixed plate 13 and the fixed seat 206 fixed at its top to move downward rapidly, and because of the fourth spring 14 arranged on the outside of the tapered screw rod 15 and the third spring 11 arranged on the outside of the multiple groups of anode rods 12, the rapid fall will be ensured while repeatedly shaking due to the elasticity of the spring, thereby increasing the contact area between the die-cast aluminum alloy plate and the electrolyte in the oxidation bin 4, thereby improving the efficiency of anodizing of the die-cast aluminum alloy plate;

[0074] When the second screw rod 304 rotates in the opposite direction, it will drive the screw moving block 305 threadedly connected to the outer side of the second screw rod 304 to move downward synchronously. Because the bottom end of the second screw rod 304 is smooth and has no threads, a part of the screw moving block 305 will still be threadedly connected to it when it moves to the bottom, so the screw moving block 305 will move downward and shake. At this time, multiple sets of second springs 307 are used to buffer the shaking of the screw moving block when it moves downward, so as to prevent it from moving too much downward and causing the entire mechanism to jam.

[0075] When the anodizing is completed, the output end of the motor 9 rotates forward again, so that the shift mechanism 2 moves upward. However, at this time, the shift mechanism 2 causes the movable base 204 to move downward as a whole due to the weight of the die-cast aluminum alloy. When the movable base 204 moves downward as a whole, it drives the first tooth plate 210 set at one end thereof to move downward, and the first gear 211 is rotated by the first tooth plate 210, so that the first gear 211, through the round rod fixed at one end thereof, synchronously rotates the second gear 212 located at the other end of the fixed seat 206;

[0076] When the second gear 212 rotates, it drives the movable plate 205 meshing with its gear on the outside to move, and the bottom of the movable plate 205 is also provided with a slide plate 207 matched with the fixed seat 206 to prevent the movable plate 205 from being dislocated while moving, so that the movable plate 205 moves outward, and the movable plate 205 located at the other end of the fixed seat 206 also performs the above steps synchronously;

[0077] Therefore, when the shift mechanism 2 is fitted with the clamping mechanism 1, the limit block will be pushed to change its angle through the die-cast aluminum alloy plate, and the moving plate 205 will produce a distance change relative to the outside, so the limit block 103 will not be squeezed during the shift mechanism 2, and the die-cast aluminum alloy will be slowly pushed into the middle of the two sets of clamping mechanisms 1 through the overall rise of the shift mechanism 2. At this time, because the movable base 204 is convex, there is enough space to cooperate with the torsion spring 106 inside the limit block 103 to reset the limit block 103, thereby achieving limit fixation;

[0078] At this time, because the positive rotation of the output end of the motor 9 can also drive the second screw rod 304 to rotate through the second bevel gear set 19, it will drive the screw moving block 305 on the outside of the oxidation bin 4 to move upward synchronously with the second screw rod 304, and the cleaning moving plate 301 fixed by the screw moving block 305 will also move upward synchronously. When the shift mechanism 2 arrives at the appropriate position, the cleaning moving plate 301 will also arrive at the predetermined position. At this time, the multiple groups of cleaning fans 303 arranged on the outside of the cleaning moving plate 301 will be started, and the cleaning fan 303 generates airflow through the rotation of the blades. This airflow can accelerate the flow speed of the air, effectively blow off or disperse most of the residual electrolyte on the die-cast aluminum alloy plate, and clean the electrolyte brought out after the anodizing process of the die-cast aluminum alloy plate, so as to prevent the die-cast aluminum alloy plate from carrying more residual electrolyte into the subsequent cleaning water washing tank;

[0079] Specifically, the multiple groups of anode rods 12 play a role in limiting and also play a role in cooperating with the die-cast aluminum alloy plate for anodizing, wherein the multiple groups of rubber limit blocks 203 arranged at one end of the abutment plate 202 can limit and fix the die-cast aluminum alloy and can reduce the contact area between the die-cast aluminum alloy and the two groups of abutment plates 202 inside the shift mechanism 2, increase the contact area between the die-cast aluminum alloy and the electrolyte inside the oxidation bin 4, and increase the efficiency of anodizing of the die-cast aluminum alloy;

[0080] Through the above structure, when the die-cast aluminum alloy is anodized, the installation of the overall production line can be more convenient, the overall engineering workload is small, and the subsequent maintenance is more convenient. When it needs to be transferred to a water tank for cleaning after the subsequent oxidation is completed, the residual electrolyte on the outside of the die-cast aluminum alloy can be cleaned by the cleaning mechanism 3 to prevent the increase of the components of the oxidizing liquid inside the subsequent water tank, thereby ensuring the cleaning efficiency of the subsequent cleaning tank for the aluminum alloy profile, thereby improving the oxidation treatment efficiency of the aluminum alloy profile.
