Aluminum alloy materials have low potential and are prone to corrosion during use. In order to make aluminum alloy materials have better corrosion resistance, anodizing treatment can be performed on the surface of aluminum alloy materials to form a protective film.

[0031] See also Figures 4 to 8 The shaking mechanism includes a lifting frame 4 which is slidably installed at the bottom of the inner cavity of the placement box 3. The front and rear sides of the lifting frame 4 are both symmetrically fixedly connected with convex blocks 41. The upper end of the lifting frame 4 is equidistantly fixedly connected with a plurality of fan-shaped support plates 42. The lower ends of the left and right sides of the placement box 3 are both recessed upwards and have lifting grooves 32. The left and right sides of the placement box 3 are symmetrically fixedly connected with guide seats 39. The guide seat 39 is provided with a groove on one side close to the placement box 3. The left and right outer sides of the placement box 3 are symmetrically installed with shaking plates 43. The lower ends of the two shaking plates 43 that are close to each other are protruded with a protrusion, which passes through the lifting groove 32 and is fixedly connected to one side of the lifting frame 4. The upper end of the shaking plate 43 passes through the groove of the guide seat 39, and the upper end of the shaking plate 43 away from the placement box 3 is fixedly connected with a cylinder 44. The left and right inner walls of the concave lifting frame 2 are symmetrically fixedly connected with fan-shaped transmission seats 45. The fan-shaped transmission seat 45 is arranged on the side of the shaking plate 43, and the side of the fan-shaped transmission seat 45 is provided with a corrugated groove 46.

[0032] The convex block 41 is slidably connected to the convex groove 31 up and down, the raised portion at the lower end of the side of the shaking plate 43 is slidably connected to the lifting groove 32 up and down, the shaking plate 43 is slidably connected to the groove on the side of the guide seat 39 up and down, the cylinder 44 is plugged into the corrugated groove 46, and the cylinder 44 is slidably connected to the corrugated groove 46.

[0033] When the lifting frame 4 moves up and down along the inner cavity of the placement box 3, the lifting frame 4 drives the fan-shaped support plate 42 to slide up and down along the inner wall of the placement box 3. At the same time, the lifting frame 4 drives the convex block 41 to slide up and down along the convex groove 31, so that the lifting frame 4 can drive the fan-shaped support plate 42 to move up and down stably.

[0034] When the placing box 3 swings back and forth, the shaking plate 43 is driven to swing back and forth. When the shaking plate 43 swings, the cylinder 44 on the side thereof slides along the corrugated groove 46 on the side of the fan-shaped transmission seat 45. At this time, the cylinder 44 moves up and down along the corrugated groove 46, and the cylinder 44 drives the shaking plate 43 to move up and down synchronously, so that the shaking plate 43 shakes up and down while swinging back and forth, and the shaking plate 43 drives the lifting frame 4 and the fan-shaped support plate 42 to shake up and down, so that the placing box 3 drives the lifting frame 4 and the fan-shaped support plate 42 to swing back and forth, and the lifting frame 4 and the fan-shaped support plate 42 can shake up and down; The aluminum alloy material is placed across the upper ends of multiple fan-shaped support plates 42, and the placement box 3 drives the aluminum alloy material on the fan-shaped support plates 42 to swing back and forth. At the same time, the fan-shaped support plates 42 drive the aluminum alloy material to shake up and down, and the aluminum alloy material is pushed upward when the fan-shaped support plates 42 move upward, and the aluminum alloy material moves downward under the action of its own gravity. In this way, the aluminum alloy material is shaken up and down, so that the aluminum alloy material can shake back and forth while swinging back and forth, so that the surface of the aluminum alloy material will not be in contact with other components and cannot be oxidized, so that the aluminum alloy material can be oxidized without dead ends, which greatly improves the quality of the oxidation processing of the aluminum alloy material.

[0035] When the placing box 3 drives the aluminum alloy material to swing back and forth, the aluminum alloy material will not move out of the oxidation treatment liquid, so that the aluminum alloy material can always be immersed in the oxidation treatment liquid.

[0036] When the aluminum alloy material is oxidized, the placing box 3 drives the aluminum alloy material to move upward out of the oxidation tank 1. At this time, the placing box 3 is driven by the driving mechanism to continue to swing back and forth, and the drying mechanism is operated to blow hot air downward along the blowing head 22. At this time, the aluminum alloy material swings back and forth, and the shaking mechanism drives the aluminum alloy material to shake up and down, which can shake off the liquid on the aluminum alloy material. At the same time, the hot air blown downward can dry the aluminum alloy material very well, greatly improving the efficiency of drying the aluminum alloy material.

[0037] See also Figures 4 to 7 , Fig. 9 , the left and right sides of the placement box 3 are symmetrically equipped with clamping mechanisms for adjusting the position of the aluminum alloy, the clamping mechanism includes a concave transmission plate 5 slidably installed on the side of the placement box 3, both ends of the concave transmission plate 5 pass through the side of the placement box 3 to extend to the inner cavity and are fixedly connected to the positioning plate 53, one side of the concave transmission plate 5 is installed with a roller 51 through a bracket, the inner side of the concave transmission plate 5 is symmetrically fixedly connected with an elastic sheet 52, one side of the elastic sheet 52 abuts against the side of the placement box 3, a clamping plate 54 is provided on the side of the positioning plate 53 away from the concave transmission plate 5, and a plurality of sliding rods 55 are symmetrically fixedly connected to the side of the clamping plate 54 close to the positioning plate 53, and a plurality of sliding rods 55 are sleeved with clamping springs 56, and one end of the plurality of sliding rods 55 passes through the positioning plate 53 and is fixedly sleeved with a limiting ring, and an extrusion mechanism is symmetrically installed on the lower end of the concave lifting frame 2.

[0038] The slide bar 55 is slidably connected to the positioning plate 53 left and right, and two ends of the clamping spring 56 are respectively in contact with the positioning plate 53 and the clamping plate 54 .

[0039] The extrusion mechanism includes a connecting plate 6 which is symmetrically fixedly connected to the lower end of the side of the concave lifting frame 2. The lower ends of the two connecting plates 6 are fixedly connected to a fan-shaped limiting plate 61. The fan-shaped limiting plate 61 is fixedly connected to a trapezoidal extrusion block 62 on the side close to the placement box 3. The end of the trapezoidal extrusion block 62 is in extrusion contact with the roller 51.

[0040] One end of the trapezoidal extrusion block 62 away from the fan-shaped limiting plate 61 gradually shrinks inward and narrows, so that the front and rear sides of the trapezoidal extrusion block 62 present an inclined slope. When the roller 51 approaches the trapezoidal extrusion block 62, the roller 51 slides along the slope of the trapezoidal extrusion block 62 until it moves to the end of the trapezoidal extrusion block 62. During this process, the roller 51 gradually moves closer to the placement box 3.

[0041] When the placement box 3 swings back and forth, the clamping mechanism is driven to swing back and forth synchronously. When the placement box 3 moves to the bottom of the concave lifting frame 2, that is, when the placement box 3 swings to the bottom, the roller 51 in the clamping mechanism is squeezed and contacted with the trapezoidal squeezing block 62, and the roller 51 is pushed to move closer to the placement box 3 by the trapezoidal squeezing block 62. The roller 51 drives the concave transmission plate 5 to move into the placement box 3, and the concave transmission plate 5 squeezes the elastic sheet 52. At the same time, the concave transmission plate 5 drives the clamping plate 54 to move through the positioning plate 53, so that the two clamping plates 54 move closer to each other. The two clamping plates 54 cooperate to push the aluminum alloy material in the placement box 3 to move the aluminum alloy material to the middle position of the placement box 3, thereby preventing one end of the aluminum alloy material from abutting against one of the clamping plates 54 to affect the oxidation effect; During the clamping process, the clamping plate 54 drives the sliding rod 55 to slide along the positioning plate 53. At the same time, the clamping plate 54 and the positioning plate 53 cooperate to squeeze the clamping spring 56. Under the action of the elastic force of the clamping spring 56, the clamping plate 54 clamps the aluminum alloy material. At the same time, the clamping spring 56 is set to prevent the aluminum alloy material from being damaged due to excessive clamping force.

[0042] When the placement box 3 swings forward or backward from the bottom, the roller 51 moves away from the trapezoidal extrusion block 62, and the concave transmission plate 5 moves out of the placement box 3 under the action of the elastic force of the elastic sheet 52. The concave transmission plate 5 drives the positioning plate 53 and the clamping plate 54 to move, so that the clamping plate 54 is separated from the aluminum alloy material, and the clamping of the aluminum alloy material is released, and this reciprocating process is repeated, so that the aluminum alloy material can stably swing back and forth in the placement box 3 to ensure the oxidation effect.

[0043] Working principle: When the aluminum alloy material needs to be oxidized, the aluminum alloy material is placed horizontally in the placement box 3, so that the aluminum alloy material is placed across the upper ends of multiple fan-shaped support plates 42; The motor shaft of the servo motor drives the lifting stud 14 to rotate, and the lifting stud 14 drives the lifting plate 16 to move downward. The two lifting plates 16 in the two lifting transmission mechanisms drive the concave lifting frame 2 to move downward. The concave lifting frame 2 drives the A-type bracket 33 and the placement box 3 to move downward synchronously through the rotating column 34. When the placement box 3 moves downward to the lowest point, the placement box 3 drives the aluminum alloy material to immerse in the oxidation treatment liquid in the oxidation tank 1, so as to perform oxidation processing.

[0044] The piston rod of the hydraulic cylinder 36 is extended and retracted to drive the tooth plate 37 to move forward and backward. When the tooth plate 37 moves forward and backward, it pushes the gear ring 35 to rotate back and forth. The gear ring 35 drives the A-type bracket 33 to swing back and forth through the rotating column 34. The A-type bracket 33 drives the placement box 3 to swing back and forth. The placing box 3 swings back and forth while driving the shaking mechanism and the clamping mechanism to swing back and forth. At this time, the cylinder 44 in the shaking mechanism slides back and forth along the corrugated groove 46 on the side of the fan-shaped transmission seat 45. At the same time, the cylinder 44 moves up and down along the corrugated groove 46. The cylinder 44 drives the shaking plate 43 to move up and down synchronously, so that the shaking plate 43 shakes up and down while swinging back and forth. The shaking plate 43 drives the lifting frame 4 and the fan-shaped support plate 42 to shake up and down, so that the placing box 3 drives the lifting frame 4 and the fan-shaped support plate 42 to swing back and forth, and the lifting frame 4 and the fan-shaped support plate 42 can shake up and down. The fan-shaped support plate 42 is used to drive the aluminum alloy material to shake up and down, and the placement box 3 drives the aluminum alloy material to swing back and forth, so that the aluminum alloy material can shake back and forth up and down while swinging back and forth, so that the surface of the aluminum alloy material will not be in contact with other components and cannot be oxidized, so that the aluminum alloy material can be oxidized without dead ends, which greatly improves the quality of the oxidation processing of the aluminum alloy material.

[0045] When the placement box 3 swings to the bottom, the roller 51 in the clamping mechanism is squeezed and contacted with the trapezoidal extrusion block 62, so that the roller 51 drives the concave transmission plate 5 to move into the placement box 3, and the concave transmission plate 5 squeezes the elastic sheet 52. At the same time, the concave transmission plate 5 drives the clamping plate 54 to move through the positioning plate 53, so that the two clamping plates 54 move closer to each other; the aluminum alloy material is placed in the middle position of the placement box 3 through the cooperation of the two clamping plates 54, so as to prevent one end of the aluminum alloy material from abutting against one of the clamping plates 54 and affecting the oxidation effect; When the placement box 3 swings forward or backward from the bottom, the roller 51 moves away from the trapezoidal extrusion block 62, and the concave transmission plate 5 moves out of the placement box 3 under the action of the elastic force of the elastic sheet 52, so that the clamping plate 54 is separated from the aluminum alloy material, and the clamping of the aluminum alloy material is released, and this reciprocating process is repeated, so that the aluminum alloy material can stably swing back and forth in the placement box 3 to ensure the oxidation effect.

[0046] After the aluminum alloy material is oxidized, the motor shaft of the servo motor drives the lifting stud 14 to rotate in the opposite direction, so that the two lifting plates 16 in the two lifting transmission mechanisms drive the concave lifting frame 2 to move upward, and the placement box 3 moves upward synchronously, and the aluminum alloy material is driven by the placement box 3 to move upward out of the oxidation tank 1 for drainage; At this time, the placement box 3 is driven by the driving mechanism to continue to swing back and forth, and at the same time, the drying mechanism is operated to blow hot air downward along the blowing head 22; At this time, the aluminum alloy material swings back and forth, and the shaking mechanism drives the aluminum alloy material to shake up and down, which can shake off the liquid on the aluminum alloy material. At the same time, the hot air blown downward can dry the aluminum alloy material very well, greatly improving the efficiency of drying the aluminum alloy material.
