Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate processing equipment, in particular to an aluminum substrate coloring, oxidation and drying device. Background Art

[0002] After the oxidation and coloring treatment, the aluminum substrate needs to be dried to make the colored oxide film on the surface more uniform and dense. In the existing process, the aluminum substrate after oxidation, coloring and cleaning will be transported to a drying chamber, and a hot air circulation system will be used to heat the air to evaporate the moisture on the surface of the oxide film. However, these hot air circulation systems usually have relatively fixed air outlets, and the aluminum substrates placed in the drying chamber cannot be moved at any time. This leads to the problem of uneven heating on the surface of the aluminum substrate to be dried, which will cause local thermal damage on the surface of the aluminum substrate, thereby affecting the coloring quality of the aluminum substrate.

[0003] How to improve this drying device to maximize the heating uniformity of the aluminum substrate by hot air has become a technical problem that needs to be solved urgently in this field. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0022] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the present invention belong. If the definitions set forth in this section are contrary to or otherwise inconsistent with definitions set forth in the patents, patent applications, published patent applications, and other publications incorporated herein by reference, the definitions listed in this section take precedence over the definitions incorporated herein by reference.

[0025] like Figure 1As shown, combined Figure 2-4 The aluminum substrate coloring, oxidation and drying device of the present invention includes: a cabinet 1, a cabinet door 2, an air inlet pipe 3, a first swing arm 4, a driving device 5 and a hot air source. The cabinet door 2 is hingedly installed at the side opening of the cabinet 1. An air inlet 11 is opened in the middle of the top of the cabinet 1. An air outlet 12 is also opened on the top of the cabinet 1. The air inlet pipe 3 is coaxially arranged in the air inlet 11. The inside of the first swing arm 4 is hollow. The end of the air inlet pipe 3 located on the inside of the cabinet 1 is connected with the first swing arm 4. A plurality of first openings 41 are arranged in an array along the length direction on a side of the first swing arm 4 away from the top of the inner wall of the cabinet 1. The length direction of the first swing arm 4 is perpendicular to the axis of the air inlet pipe 3. The end of the air inlet pipe 3 located on the outside of the cabinet 1 is connected with the hot air source. The driving device 5 is transmission connected to the air inlet pipe 3 and can drive the air inlet pipe 3 to rotate around its axis.

[0026] In the above embodiment, after the cabinet door 2 is closed, it forms a relatively closed cavity with the cabinet body 1. The cavity is connected to the outside world through the air inlet 11 and the air outlet 12. The air inlet is used to connect to the hot air source, thereby transporting heated gas into the closed cavity, thereby drying the aluminum substrate to be processed. The air outlet 12 is used to collect the exhausted hot air and recover moisture and heat energy. The air inlet pipe 3 can be driven by the driving device 5 and rotate around its own axis. During the rotation of the air inlet pipe 3, the first swing arm 4 rotates around the axis of the air inlet pipe 3. Since a plurality of first openings 41 are provided below the first swing arm 4, these first openings 41 will transport hot air to different positions in the closed cavity as they rotate, thereby achieving uniform circulation of hot air at different positions. Compared with the solution in the prior art where the air inlet direction and air inlet position remain unchanged, the technical solution of the above embodiment can achieve a more uniform heating effect in the closed cavity.

[0027] Furthermore, in the above embodiment, the driving device 5 can be selectively driven or stopped, so that the first opening 41 stays at the target position or sweeps, thereby achieving different heating effects.

[0028] In some embodiments, a second swing arm 6 is further included. The second swing arm 6 is hollow and fixed to the end of the first swing arm 4 away from the intake pipe 3. The length direction of the second swing arm 6 is parallel to the axis of the intake pipe 3. The second swing arm 6 is close to the axis of the intake pipe 3 and is provided with a plurality of second openings 61 in an array along the length direction.

[0029] The second swing arm 6 is set vertically downward, and the first swing arm 4 is set horizontally. Therefore, during the rotation process, the first opening 41 is always facing downward, and only the air outlet position on the horizontal plane is changed. In the drying device, in order to increase the processing capacity, multiple aluminum substrates to be processed are usually stacked, so it is easy to form a temperature difference in the vertical direction. In order to solve this problem, and at the same time to allow the aluminum substrates at different heights to be heated evenly, a second swing arm 6 is set. The vertically set second swing arm 6 also rotates during the rotation of the air inlet pipe 3, so that it can move circumferentially. During the circumferential rotation, the second outlet 61 can discharge air on different horizontal planes to achieve a more uniform heating effect.

[0030] In some embodiments, an adjusting valve disc 7 is further included. The adjusting valve disc 7 is rotatably mounted inside the second opening 61 . The rotation of the adjusting valve disc 7 can change the opening of the second opening 61 .

[0031] In the above embodiment, since the heated gas is input from the air inlet pipe 3, it will preferentially flow through the first opening 41 and the second opening 61 above. The gas outlet volume and gas outlet temperature of the second opening 61 below are easily restricted. In order to avoid this situation, an adjustment valve plate 7 is provided on the second opening 61. The adjustment valve plate 7 can be used to adjust the opening of different second openings 61 to achieve the most uniform heating effect. The adjustment valve plate 7 can be rotated inside the second opening 61 by pin connection, and the position of the adjustment valve plate can be fixed or adjusted by a tight fit or damping structure.

[0032] In some embodiments, a bearing 8 is further included, and the intake pipe 3 is coaxially fixedly installed in the intake port 11 through the bearing 8 .

[0033] In the above embodiments, the bearing 8 is used to rotatably connect the air inlet pipe 3 and the cabinet 1 .

[0034] In some embodiments, the driving device 5 includes a belt 51 and a driving motor 52. The driving motor 52 is fixed above the cabinet 1. A pulley 53 is coaxially keyed on the driving shaft of the driving motor 52. The pulley 53 is connected to the air intake pipe 3 through a belt 51.

[0035] In the above embodiments, the driving motor 52 can adopt a stepping motor or a servo motor with high-precision control. Through precise rotation angle control, the first swing arm 4 and the second swing arm 6 can be stopped at the preset position to achieve the expected heating effect.

[0036] In some embodiments, a rotary joint 9 is further included, and the air outlet of the hot air source is connected to an opening at one end of the air inlet pipe 3 located outside the cabinet 1 through the rotary joint 9 .

[0037] In the above embodiment, the rotary joint 9 is used to connect the hot air source and the air inlet pipe 3. Since the air inlet pipe 3 needs to rotate, the rotary joint 9 is used to ensure normal interface connection, rotation and sealing. The hot air source can be a hot air blower or other existing equipment that can generate hot air.

[0038] In some embodiments, a multi-layer storage rack 10 is further included. The multi-layer storage rack 10 is fixed to the inner bottom surface of the cabinet 1 . The multi-layer storage rack 10 is provided with multiple layers of parallel storage boards 101 along the height direction.

[0039] In the above embodiment, the multi-layer storage rack 10 is used to place the aluminum substrate to be processed, and the storage plate 101 can be a porous mesh plate to ensure support performance and air permeability.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
