Description

Technical Field

[0001] This utility model relates to the field of aluminum profile anodizing technology, specifically to an anodizing and immersion coloring processing equipment. Background Technology

[0002] In the existing processing equipment for anodizing and coloring aluminum profiles, the stirring mechanism of the equipment usually only uses a single stirring mechanism to stir the electrolyte. This results in insufficient stirring of the electrolyte inside the processing equipment, causing uneven distribution of electrolyte concentration and inconsistent oxide film thickness on the surface of the aluminum profile. Consequently, the quality of the oxide film on the surface of the aluminum profile is affected, which brings certain inconveniences to the subsequent use of the aluminum profile.

[0003] Utility model CN219824388U discloses an anodizing and immersion coloring processing device for aluminum profiles, including a reaction chamber. A stirring motor is movably connected to one side of the reaction chamber, and a main stirring column is fixedly connected to one end of the stirring motor. A main stirring blade is fixedly connected to the surface of the main stirring column. This utility model uses a stirring motor to drive the main stirring column, the main stirring blade, and the drive gear to rotate, which is beneficial for stirring the electrolyte inside the reaction chamber. At the same time, through the meshing connection between the drive gear and the first driven gear and the second driven gear, the drive gear can drive the first driven gear and the second driven gear to rotate in both directions, thereby driving the first auxiliary stirring column and the first auxiliary stirring blade, as well as the second auxiliary stirring column and the second auxiliary stirring blade, to rotate in both directions. This fully stirs the electrolyte inside the reaction chamber, making the electrolyte concentration distribution uniform and improving the quality of the oxide film on the aluminum profile.

[0004] However, the above-mentioned existing technologies still have the following shortcomings when used: 1. A stirring structure is set in the reaction tank to improve the uniformity of the electrolyte. However, this method has the risk of workpiece falling and colliding. That is to say, when the workpiece is accidentally dropped, it will come into contact with the stirring structure, which can easily damage the stirring structure; 2. The workpiece is transported into the reaction tank by an electric telescopic rod and a clamp. Since the workpiece is positioned by clamping, the workpiece loading and unloading operation is inconvenient. Moreover, the number of workpieces carried at one time is small, which affects the efficiency of oxidation processing.

[0005] Therefore, this utility model provides an anodizing and immersion coloring processing equipment. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anodizing and immersion coloring processing equipment to solve the problems mentioned in the background technology. This utility model has the advantages of making the electrolyte concentration uniform while making the oxidation process safer, and also has the advantages of convenient workpiece loading and unloading operation and improved oxidation process efficiency.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an anodizing and immersion coloring processing device, comprising a base and a reaction tank located on the base, wherein a perforated mesh plate is provided inside the reaction tank, which divides the inner cavity of the reaction tank into an upper oxidation chamber and a lower impact chamber, a transmission and filtration pipeline is provided outside the reaction tank, the upper oxidation chamber is connected to the lower impact chamber through the transmission and filtration pipeline, a groove-shaped support frame located on one side of the reaction tank is rotatably connected to the top of the base, a portal-shaped suspension frame is rotatably connected to the top of the groove-shaped support frame, a suspension bracket is provided at the bottom of the portal-shaped suspension frame, and a control cylinder for controlling the swing of the groove-shaped support frame is provided on the base.

[0008] Furthermore, a water pump and a filter cylinder are connected in series on the transmission and filtration pipeline, and one end of the transmission and filtration pipeline is fixedly connected to a liquid outlet ring pipe located in the lower impact chamber. The outer peripheral wall of the liquid outlet ring pipe is provided with uniformly distributed liquid outlet holes.

[0009] Furthermore, the other end of the transmission filter pipeline is fixedly connected to an inlet ring pipe located in the upper oxidation chamber, and the outer peripheral wall of the inlet ring pipe is provided with uniformly distributed inlet through holes.

[0010] Furthermore, the two ends of the crossbeam at the top of the portal frame are rotatably connected to the top of the channel support frame, and a cantilever is welded to one side of the channel support frame. One end of the cantilever is hinged to the top of the base via a control cylinder.

[0011] Furthermore, the suspension bracket includes a support shaft and at least two support plates disposed on the support shaft, wherein the at least two support plates are arranged in parallel and the support shaft is perpendicular, and the two ends of the support shaft are fixedly connected to the bottom of opposite side walls inside the portal suspension bracket.

[0012] Furthermore, a row of stop bars arranged along the length direction is welded to the top of the pallet, and a guide sleeve sleeved on the support shaft is fixedly connected to the middle of the pallet, with the guide sleeve and the support shaft slidingly engaged axially.

[0013] Furthermore, the guide sleeve and the support shaft are clearance-fitted, and a locking bolt that works with the support shaft is screwed through one side of the guide sleeve.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a perforated mesh plate in the reaction tank, the perforated mesh plate can buffer the impact force of falling workpieces and prevent the workpieces from causing impact damage to the bottom of the reaction tank. Then, a transmission filter pipeline is set so that the electrolyte in the reaction tank flows upward through the perforated mesh plate, thereby improving the uniformity of electrolyte concentration.

[0016] 2. In this utility model, a channel-shaped support is set on the base, and a gate-shaped suspension frame is set on the top of the channel-shaped support. When the channel-shaped support swings, the gate-shaped suspension frame is in a free suspension and remains vertical. A suspension bracket for supporting the workpiece is set at the bottom of the gate-shaped suspension frame. When the channel-shaped support swings, the workpiece will enter and exit the reaction tank in the form of an arc motion trajectory. This makes the loading and unloading of the workpiece more convenient.

[0017] 3. In this utility model, by setting a tray on the suspension bracket and then setting a row of baffles on the tray, the aluminum profile is placed between adjacent baffles during use. This arrangement can increase the number of aluminum profiles that can be placed at one time and improve the efficiency of the anodizing process. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 3This utility model provides a technical solution: an anodizing and immersion coloring processing device, including a base 6 and a reaction tank 1 located on the base 6. Anodizing electrolyte is injected into the reaction tank 1. A perforated mesh plate 2 is installed inside the reaction tank 1, serving to withstand the impact of falling workpieces. The perforated mesh plate 2 has evenly distributed water passage holes, dividing the inner cavity of the reaction tank 1 into an upper oxidation chamber 3 and a lower impact chamber 4. The upper oxidation chamber 3 is the cavity for workpiece oxidation treatment. A transmission and filtration pipeline 5 is installed outside the reaction tank 1, connecting the upper oxidation chamber 3 and the lower impact chamber 4. That is, the transmission and filtration pipeline 5 transmits the electrolyte in the upper oxidation chamber 3 to the lower impact chamber 4, while the electrolyte in the lower impact chamber 4 passes through the perforated mesh plate 2 and is sprayed with water into the upper oxidation chamber 3. This ensures that the electrolyte in the reaction tank 1 is in a state of full flow, improving the uniformity of the electrolyte concentration.

[0024] Specifically, a water pump 51 and a filter cylinder 52 are connected in series on the transmission and filtration pipeline 5. The function of the filter cylinder 52 is to filter out impurities in the electrolyte (such as aluminum chips, oxide scale, and dirt on the surface of the workpiece). One end of the transmission and filtration pipeline 5 is fixedly connected to an outlet ring pipe 53 located in the lower impact chamber 4. The outer peripheral wall of the outlet ring pipe 53 has uniformly distributed outlet holes 531. After water is discharged from the outlet ring pipe 53, it will be evenly sprayed into the lower impact chamber 4 through the outlet holes 531, so that the electrolyte is in a turbulent state, which can effectively avoid uneven electrolyte concentration.

[0025] Furthermore, the other end of the transmission filter pipe 5 is fixedly connected to an inlet ring pipe 54 located in the upper oxidation chamber 3. The outer peripheral wall of the inlet ring pipe 54 is provided with uniformly distributed inlet through holes 541. The electrolyte in the upper oxidation chamber 3 enters the inlet ring pipe 54 through the inlet through holes 541. This arrangement allows the electrolyte in the upper oxidation chamber 3 to be in a state of large-scale and comprehensive flow, further improving the fluidity of the electrolyte.

[0026] A trough-shaped support frame 7 located on one side of the reaction tank 1 is rotatably connected to the top of the base 6. The bottom of the trough-shaped support frame 7 is hinged to the base 6. A portal-shaped suspension frame 8 is rotatably connected to the top of the trough-shaped support frame 7. When the trough-shaped support frame 7 swings to an inclined position, the portal-shaped suspension frame 8 is vertically suspended by its own weight. A suspension bracket 9 is provided at the bottom of the portal-shaped suspension frame 8. The function of the suspension bracket 9 is to support aluminum profiles (such as aluminum tubes). When the trough-shaped support frame 7 swings left and right, it can send the workpiece into the upper oxidation chamber 3 and move the workpiece out to the top of the base 6. This arrangement increases the space for loading and unloading workpieces and improves the convenience of workpiece loading and unloading operations. A control cylinder 101 is provided on the base 6 to control the swing of the trough-shaped support frame 7. The control cylinder 101 provides driving force for the swing of the trough-shaped support frame 7.

[0027] In this embodiment, the two ends of the crossbeam 81 at the top of the portal frame 8 are rotatably connected to the top of the channel support 7. A cantilever 71 is welded to one side of the channel support 7. One end of the cantilever 71 is hinged to the top of the base 6 through the control cylinder 101. When the control cylinder 101 moves, it will drive the channel support 7 to swing left and right through the cantilever 71. This arrangement can increase the amplitude of the left and right swing of the channel support 7.

[0028] In this embodiment, the suspension bracket 9 includes a support shaft 91 and at least two support plates 92 disposed on the support shaft 91. The at least two support plates 92 are arranged in parallel and perpendicular to the support shaft 91. The function of the support plates 92 is to support the workpiece. The two ends of the support shaft 91 are fixedly connected to the bottom of the opposite side walls inside the portal-type suspension bracket 8.

[0029] Furthermore, a row of stop bars 921 arranged along the length direction is welded to the top of the pallet 92. The positions between adjacent stop bars 921 are used to place aluminum profile workpieces. The arrangement of the row of stop bars 921 allows the two pallets 92 to carry multiple aluminum profile workpieces. A guide sleeve 922 is fixedly connected to the middle of the pallet 92 and sleeved on the support shaft 91. The guide sleeve 922 and the support shaft 91 are axially slidingly engaged. This arrangement facilitates adjustment of the distance between the two pallets 92 and makes it easy to lift aluminum profiles of different lengths. The guide sleeve 922 and the support shaft 91 are clearance-fitted. A locking bolt 102 for use with the support shaft 91 is screwed through one side of the guide sleeve 922. The function of the locking bolt 102 is to fasten the guide sleeve 922 and the support shaft 91.

[0030] Working principle: When in use, the water pump 51 is started, and the electrolyte in the upper oxidation chamber 3 is transferred to the lower impact chamber 4 through the transmission filter pipe 5. The electrolyte in the lower impact chamber 4 passes through the perforated mesh plate 2 and enters the upper oxidation chamber 3. At this time, the electrolyte in the reaction tank 1 is in a state of full flow, and there will be no problem of uneven concentration. The aluminum profile is placed between the adjacent baffles 921 on the two support plates 92, and then the control cylinder 101 is started. At this time, the trough support 7 swings towards the reaction tank 1, the gantry suspension 8 remains vertical and transfers the lower aluminum profile to the upper oxidation chamber 3 to achieve the oxidation of the aluminum profile. After the oxidation treatment is completed, the trough support 7 is controlled to swing in the opposite direction to transfer the aluminum profile to the outside of the reaction tank 1, and then the aluminum profile on the support plate 92 can be removed.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
