Description

Technical Field

[0001] The invention relates to the field of aluminum plates, and in particular to a self-cleaning spray-painted aluminum plate and a preparation device thereof. Background Art

[0002] Spray-painted aluminum sheet is a functional material with aluminum sheet as the base material, which is formed with decorative patterns, colors or textures through surface spray painting process. It has both the physical properties of the metal base material and the decorativeness of the spray-painted layer. It is widely used in decoration, advertising, construction and other fields. The self-cleaning function is achieved by setting a special coating on the surface of the aluminum sheet. The common super-hydrophilic photocatalytic coating is a type of self-cleaning coating. The TO2 coating makes the stains active under light conditions, and then forms a uniform water film for flushing through the super-hydrophilic properties.

[0003] In the production process of combining the above-mentioned self-cleaning coating and spray-painted aluminum plate, since the TO2 coating may decompose the ink spray-painted layer and cause the pattern to be lost, an isolation layer needs to be set. This causes the aluminum plate to have a multi-layer structure including a primer, an ink layer, an isolation layer, and a cleaning layer. During the processing, it needs to be cured layer by layer. Each curing process requires coating / spraying, fixing the aluminum plate, placing it in a curing device, and removing the aluminum plate after curing. The processing process is cumbersome, and the conventional curing device has a complicated process of disassembling and assembling the aluminum plate, which is not suitable for this multi-layer aluminum plate structure. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-cleaning spray-painted aluminum plate and a preparation device thereof, which solves the problem of complicated working procedures caused by frequent disassembly and assembly of aluminum plates in existing preparation devices.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: A device for preparing self-cleaning spray-painted aluminum plates includes several curing chambers and a placement rack for carrying aluminum plates into the curing chambers for coating curing. The placement rack is provided with a placement layer with adjustable layer spacing, and the placement layer is provided with several movable clamping units, wherein the clamping units include a slider, a sliding rod telescopically arranged at the bottom of the slider, a base plate arranged at the bottom of the sliding rod, and an articulated arm arranged on the base plate and inclined upward. The articulated arm is used to push the sliding rod and the slider to move laterally when the sliding rod is pushed upward to clamp the aluminum plate.

[0006] As a preferred solution of the present invention, the placement layer includes a first cross bar and several second cross bars vertically connected to the first cross bar, wherein the second cross bar is provided with an inner groove and a slide groove, and the clamping unit moves along the slide groove. In this solution, the placement layer is set as a structure of multiple staggered cross bars, which is conducive to reducing weight, and the gaps between different placement layers are conducive to ventilation and improving curing efficiency.

[0007] As a preferred solution of the present invention, the placement rack includes a base, movable wheels arranged under the base, and a column arranged above the base. A sliding sleeve is provided at the end of the first cross bar, and the sliding sleeve and the column can be fixedly slidably connected. Since some aluminum plates need to be folded, the thickness after folding is quite different from that of the flat aluminum plates without folding. Therefore, this method makes the spacing between the placement layers adjustable, thereby improving the compatibility of the device with the production of different batches of products. For thin aluminum plates, the spacing between the placement layers can be reduced, thereby improving the curing efficiency.

[0008] As a preferred solution of the present invention, the clamping unit also includes a clamping block arranged at the upper end of the slider, wherein a first elastic member is provided in the clamping block for causing the slide bar to slide downward, and a protrusion is provided on the inner wall of the second cross bar along both sides of the slide groove, and the gap between the protrusions is used to clamp the hinged arm. This solution uses the hinged arm and the protrusion to allow the clamping unit to slide freely along the second cross bar when not clamped, so as to adjust the position to adapt to aluminum plates of different widths. When the slide bar is pushed upward, the hinged arm is clamped into the gap between the protrusions, thereby driving the clamping block to move laterally and applying a lateral clamping force.

[0009] As a preferred solution of the present invention, the articulated arm is driven by a torsion spring provided on the shaft portion to rotate upward, and the shaft portion is provided with a limiter so that the articulated arm tends to tilt upward.

[0010] As a preferred solution of the present invention, the cross-section of the slider is elliptical, and the slider rotates axially in a clamping manner in the slide groove. The slider provided in this solution can rotate 180° along its own axis to facilitate the change of the direction of the articulated arm, so that different clamping units can provide opposite lateral clamping forces after reversing the direction. This effect is that for the folded aluminum plate, it is different from the flat aluminum plate, and the outer fold is generally coated. Therefore, the clamping direction should be supported from the inside of the fold to the outside. Therefore, the clamping unit of this solution can be applied to the folded aluminum plate after the direction is changed, which further improves the compatibility.

[0011] As a preferred solution of the present invention, a driving device is provided inside the first cross bar and the inner groove for pushing the slide bar upward, the driving device includes a vertical slide plate that slides vertically along the inner groove, a cross slide plate that slides horizontally in the inner groove, a plurality of first trapezoidal blocks are provided at intervals on the bottom of the cross slide plate, and a second trapezoidal block that is inserted into the gap between the first trapezoidal blocks is provided under the vertical slide plate, for driving the cross slide plate to push the vertical slide plate upward when the cross slide plate slides. This solution sets up a driving device, and in each second cross bar, by pulling the cross slide plate, the vertical slide plate slides upward, and squeezes multiple slide bars at the same time, wherein the vertical slide plate can be provided with a vertical stripe guide structure as needed to prevent it from sliding horizontally.

[0012] As a preferred solution of the present invention, a pull plate is provided for sliding inside the first cross bar, and a pull arm is vertically extended from one end of the pull plate for pulling outside, wherein a first oblique push block is provided on the surface of the pull plate, and a second oblique push block is provided at the end of the cross slide plate for pushing the cross slide plate when the pull plate is pulled, and a second elastic member for resetting the cross slide plate is also provided between the cross slide plate and the inner groove. In order to improve the locking and unlocking efficiency of the clamping unit, this solution provides a pull plate on the placement layer, and drives all the cross slide plates of the placement layer to slide through the pull plate.

[0013] In order to apply the above-mentioned preparation device, the present invention also proposes a self-cleaning spray-painted aluminum plate, which is obtained by curing through any of the above-mentioned preparation devices, wherein the spray-painted aluminum plate includes: an aluminum plate layer, a primer layer, an ink layer, an isolation layer, and a titanium dioxide cleaning layer.

[0014] The beneficial effect of the present invention is that by setting up several clamping units, the aluminum single plate can be clamped to facilitate the fixation of the aluminum plate, improve the disassembly and assembly efficiency, and thus improve the curing efficiency. The clamping unit can adapt to aluminum plates of different sizes, and the clamping method can not only clamp from the outside, but also clamp from the inside, so it can be applied to flat aluminum plates and folded aluminum plates, with strong compatibility, and is particularly suitable for the production of small batches of spray-painted aluminum plates.

[0016] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 like Figure 1-8 As shown, a self-cleaning spray-painted aluminum plate preparation device includes a plurality of curing chambers 1 and a display rack 2 for carrying aluminum plates into the curing chambers 1 for coating curing. The display rack 2 is provided with a placement layer 3 with adjustable layer spacing, and the placement layer 3 is provided with a plurality of movable clamping units 4, wherein the clamping unit 4 includes a slider 41, a slide rod 42 telescopically arranged at the bottom of the slider 41, a bottom plate arranged at the bottom of the slide rod 42, and an articulated arm 45 arranged on the bottom plate and inclined upward. The articulated arm 45 is used to push the slide rod 42 and the slider 41 to move laterally when the slide rod 42 is pushed upward to clamp the aluminum plate.

[0018] This solution can clamp the aluminum single plate by setting up several clamping units 4 to facilitate the fixation of the aluminum plate, improve the disassembly and assembly efficiency, and thus improve the curing efficiency. The clamping unit 4 can adapt to aluminum plates of different sizes, and the clamping method can not only clamp from the outside, but also clamp from the inside. Therefore, it can be applied to flat aluminum plates 6 and folded aluminum plates 7. It has strong compatibility and is particularly suitable for the production of small batches of spray-painted aluminum plates.

[0019] It should be noted that different layers use different curing chambers 1. For example, the primer needs high temperature curing, the spray-painted layer needs light curing, and the titanium dioxide cleaning layer needs room temperature drying and curing.

[0020] As an embodiment, the placement layer 3 includes a first cross bar 31 and several second cross bars 32 vertically connected to the first cross bar 31, wherein the second cross bar 32 is provided with an inner groove 33 and a slide groove 34, and the clamping unit 4 moves along the slide groove 34. In this solution, the placement layer 3 is set as a structure of multiple staggered cross bars, which is conducive to reducing weight, and the gaps between different placement layers are conducive to ventilation and improving curing efficiency.

[0021] During use, since some aluminum plates need to be folded, the thickness after folding is quite different from that of the flat aluminum plates without folding. In order to improve the compatibility of the device with the production of different batches of products, the display rack 2 of this embodiment includes a base 21, a movable wheel 23 arranged below the base 21, and a column 22 arranged above the base 21. A sliding sleeve 36 is provided at the end of the first cross bar 31, and the sliding sleeve 36 can be fixedly slidably connected to the column 22. In this way, the spacing of the placement layers 3 can be adjusted. For thin aluminum plates 6, the spacing of the placement layers 3 can be reduced, thereby improving the curing efficiency.

[0022] The clamping unit 4 also includes a clamping block 43 arranged at the upper end of the slider 41, wherein a first elastic member 44 is provided in the clamping block 43 for causing the slide bar 42 to slide downward, and a protrusion 35 is provided on the inner wall of the second cross bar 32 along both sides of the slide groove 34, and the gap between the protrusion 35 is used to clamp the hinged arm 45. This solution uses the hinged arm 45 and the protrusion 35 to allow the clamping unit 4 to slide freely along the second cross bar 32 when not clamped, so as to adjust the position to adapt to aluminum plates of different widths. When the slide bar 42 is pushed upward, the hinged arm 45 is clamped into the gap between the protrusion 35, thereby driving the clamping block 43 to move laterally and apply a lateral clamping force. It should be noted that the initial position of the hinged arm 45 when it is clamped into the protrusion 35 is different, and the slide bar 42 needs to have a certain deformation ability.

[0023] The articulated arm 45 is driven by the torsion spring provided on the shaft portion to rotate upward, and the shaft portion is provided with a limiter, so that the articulated arm 45 tends to tilt upward.

[0024] The cross-section of the slider 41 is elliptical, and the slider 41 is axially rotated in a clamping manner within the slide groove 34. The slider 41 provided in this solution can be rotated 180° along its own axis to facilitate the change in the orientation of the articulated arm 45, so that different clamping units 4 can provide opposite lateral clamping forces after reversing the orientation. This effect is that for the folded aluminum plate 7, it is different from the flat aluminum plate 6, and the outer fold is generally coated. Therefore, the clamping direction should be supported from the inside of the fold to the outside. Therefore, the clamping unit 4 of this solution can be applied to the folded aluminum plate 7 after the direction is changed, which further improves the compatibility.

[0025] A driving device 5 is provided inside the first cross bar 31 and the inner groove 33 for pushing the slide bar 42 upward. The driving device 5 includes a vertical slide plate 53 that slides vertically along the inner groove 33, and a cross slide plate 51 that slides laterally along the inner groove 33. Several first trapezoidal blocks 52 are provided at intervals at the bottom of the cross slide plate 51, and a second trapezoidal block 59 that is inserted into the gap between the first trapezoidal blocks 52 is provided below the vertical slide plate 53 for driving the cross slide plate 51 to push the vertical slide plate 53 upward when the cross slide plate 51 slides. In this scheme, a driving device 5 is provided. In each second cross bar 32, the cross slide plate 51 is pulled to squeeze the vertical slide plate 53 to slide upward, and at the same time squeeze multiple slide bars 42. The vertical slide plate 53 can be provided with a vertical stripe guide structure as needed to prevent it from sliding laterally.

[0026] A pull plate 56 is provided for sliding inside the first cross bar 31, and a pull arm 58 is vertically extended from one end of the pull plate 56 for external pulling, wherein a first oblique push block 55 is provided on the surface of the pull plate 56, and a second oblique push block 57 is provided at the end of the cross slide 51 for pushing the cross slide 51 when the pull plate 56 is pulled, and a second elastic member 54 for resetting the cross slide 51 is also provided between the cross slide 51 and the inner groove 33. In order to improve the locking and unlocking efficiency of the clamping unit 4, this scheme provides a pull plate 56 on the placement layer 3, and drives all the cross slides 51 of the placement layer 3 to slide through the pull plate 56.

[0027] In order to apply the above-mentioned preparation device, the present invention also proposes a self-cleaning spray-painted aluminum plate, which is obtained by curing through any of the above-mentioned preparation devices, wherein the spray-painted aluminum plate includes: an aluminum plate layer, a primer layer, an ink layer, an isolation layer, and a titanium dioxide cleaning layer.

[0028] Specific implementation method: When curing, the clamping unit 4 is moved to the approximate position according to the size of the aluminum plate in advance, the aluminum plate is placed, the clamping unit 4 is pushed against the edge of the aluminum plate, and then the pulling arm 58 is pulled to make the pulling plate 56 push the horizontal slide 51 through the second inclined push block 57. The horizontal slide 51 pushes up the vertical slide 53 through the first trapezoidal block 52, and then pushes the slide bar 42 upward. Due to the different inclination directions of the hinged arm 45, when the slide bar 42 moves upward, the hinged arm 45 is stuck in the gap of the protrusion 35, and the lateral thrust generated on the slide bar 42 causes the clamping block 43 to clamp the aluminum plate. Figure 5 As shown, the flat aluminum plate 6 is clamped; When the folded aluminum plate 7 needs to be clamped, Figure 7As shown, the clamping unit 4 is rotated first, and the slide bar 42 and the slider 41 can only slide but not rotate. Therefore, when the clamping block 43 is rotated, the slider 41 with elasticity and an elliptical cross-section rotates 180°, and drives the slide bar 42 to rotate, and turns the direction of the hinged arm 45. When the slide bar 42 is pushed upward, the inner wall of the folded aluminum plate 7 is squeezed to both sides. It should be noted that the initial position of the clamping unit 4 is different. After the folded aluminum plate 7 is placed, the clamping unit 4 does not necessarily rest against the inner wall of the fold, and there may be a short distance. In this case, the pulling arm 58 can be repeatedly pulled multiple times so that the clamping unit 4 can move a small amount in the inclined direction of the hinged arm 45, and then rest against the inner wall of the fold. For the clamping unit 4 that has already rested against the inner wall of the fold, it will stay where it is when the pulling arm 58 is repeatedly pulled.

[0029] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
