Abstract
Description
Technical Field
[0001] This patent relates to the field of aluminum foil coating equipment, and more particularly to an equipment for coating ceramic aluminum foil / aluminum strip. Background Technology
[0002] Patent CN216763746U discloses an aluminum foil transport structure with a painting function. During the aluminum foil / strip painting process, atomized paint is sprayed onto the aluminum foil conveyed on the transport device via a nozzle. Paint accumulates on the un-covered portions of the conveyor rollers. The conveying of the aluminum foil / strip can cause skew, and the repeated skewing of the aluminum foil / strip rubs against the accumulated paint, resulting in uneven paint layers at the edges of the aluminum foil / strip, and even paint adhering to the bottom of the aluminum foil / strip, creating defects in the painting quality. If the aluminum foil / strip has a ceramic coating, it will affect the overall insulation performance of the ceramic aluminum foil / strip. Utility Model Content
[0003] The purpose of this application is to address the shortcomings of existing technologies by proposing an apparatus for coating ceramic aluminum foil / aluminum strip, eliminating the influence of paint splashing from idler rollers, thereby improving the uniformity of the insulating paint film on the surface of ceramic aluminum foil / aluminum strip.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An apparatus for coating ceramic aluminum foil / aluminum strip includes a frame, a take-up roller is provided on one side of the frame, a pressure roller and two support rollers are rotatably connected inside the frame, a spraying frame is fixedly connected to the upper side of the frame, and at least two pad rollers are symmetrically arranged on the frame between the two support rollers. The pad rollers are removed from the bottom of the aluminum foil / aluminum strip by a pulling device.
[0006] The extraction device includes a tray, an installation slot on the frame, a first electric push rod fixedly connected to the bottom of the installation slot, the tray fixedly connected to the upper end of the first electric push rod, a slider slidably connected to the tray, a pad roller rotatably connected to one side of the slider, and a second electric push rod fixedly connected to the tray, the telescopic end of the second electric push rod being fixedly connected to the slider.
[0007] Preferably, the pad roller is tapered, and a controller is fixedly connected to one side of the frame. The controller is used to coordinate the control of the first electric push rod and the second electric push rod so that the pad roller moves obliquely upward along its own tapered direction towards the aluminum foil / aluminum strip.
[0008] Preferably, the inner wall of the pad roller is provided with a cavity, a suction sleeve is fixedly connected to one side of the slider, the suction sleeve is coaxial with the pad roller, and the pad roller is provided with suction holes evenly.
[0009] Preferably, the conical surface of the pad roller is uniformly provided with annular grooves.
[0010] Preferably, the air intake holes are evenly distributed at the bottom of the annular groove.
[0011] Preferably, a scraper is fixedly connected to one side of the slider.
[0012] The advantages of this application are as follows: The provided device for coating ceramic aluminum foil / aluminum strip uses a controller to move the pad roller obliquely upwards along its own taper towards the ceramic aluminum foil / aluminum strip. The pad roller is always in contact with the aluminum foil / aluminum strip, and the part of the pad roller that is splashed with paint gradually moves away from the ceramic aluminum foil / aluminum strip, thereby avoiding affecting the painting of the edge of the ceramic aluminum foil / aluminum strip. At the same time, the part of the pad roller that was originally covered by the ceramic aluminum foil / aluminum strip (the clean part) is replaced by the part of the pad roller that was covered with paint due to the movement of the pad roller. When the ceramic aluminum foil / aluminum strip is offset, the amount of paint scraped by the edge of the ceramic aluminum foil / aluminum strip on the pad roller is reduced, thereby improving the uniformity of the insulating varnish film at the edge of the ceramic aluminum foil / aluminum strip.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of this application.
[0020] like Figures 1 to 6As shown, an apparatus for coating ceramic aluminum foil / aluminum strip includes a frame 1. A take-up roller 11 is provided on one side of the frame 1. A pressure roller 12 and two support rollers 13 are rotatably connected inside the frame 1. The aluminum foil / aluminum strip 10 is supported above the two support rollers 13. One of the pressure rollers 12 and support rollers 13 is close to the take-up roller 11, and the aluminum foil / aluminum strip 10 passes through between them, so that the aluminum foil / aluminum strip 10 is always at the same plane height. A spray painting frame 14 is fixedly connected to the upper side of the frame 1. At least two pad rollers 2 are symmetrically arranged on the frame 1 between the two support rollers 13. After the aluminum foil / aluminum strip 10 is limited in height by the pressure roller 12 and support roller 13, it is attached to the pad roller 2. When the aluminum foil / aluminum strip 10 is conveyed, the pad roller 2 is driven to rotate by friction. The pad roller 2 is removed from the bottom of the aluminum foil / aluminum strip 10 by a pulling device 3.
[0021] The extraction device 3 includes a support plate 31 and an installation slot 32 on the frame 1. The bottom of the installation slot 32 is fixedly connected to a first electric push rod 33. The support plate 31 is fixedly connected to the upper end of the first electric push rod 33. The support plate 31 is slidably connected to a slider 34. The pad roller 2 is rotatably connected to one side of the slider 34. The support plate 31 is fixedly connected to a second electric push rod 35. The telescopic end of the second electric push rod 35 is fixedly connected to the slider 34.
[0022] The pad roller 2 is conical. A controller 36 is fixedly connected to one side of the frame 1. The controller 36 is used to coordinate the control of the first electric push rod 33 and the second electric push rod 35 so that the pad roller 2 moves obliquely upward along its own taper towards the aluminum foil / aluminum strip 10. The controller 36 controls the vertical movement speed of the pallet 31 through the first electric push rod 33 and controls the horizontal movement speed of the slider 34 through the second electric push rod 35, so that the pad roller 2 forms a compound motion in the vertical and horizontal directions. The pad roller 2 can move according to the required motion trajectory.
[0023] The controller 36 causes the pad roller 2 to move obliquely upward along its own taper towards the aluminum foil / aluminum strip 10. Figure 4 In the direction of A), the pad roller 2 is always in contact with the aluminum foil / aluminum strip 10, and the part of the pad roller 2 that is splashed with paint gradually moves away from the aluminum foil / aluminum strip 10, thereby avoiding affecting the paint spraying on the edge of the aluminum foil / aluminum strip 10. At the same time, the part of the pad roller 2 that was originally covered by the aluminum foil / aluminum strip 10 (the clean part) is replaced by the part of the pad roller 2 that was covered by paint due to the movement of the pad roller 2. When the aluminum foil / aluminum strip 10 shifts, the amount of paint scraped on the pad roller 2 by the edge of the aluminum foil / aluminum strip 10 is reduced, thereby improving the quality of the paint on the edge of the aluminum foil / aluminum strip 10.
[0024] Two sets of pad rollers 2 are set up, with two pad rollers 2 symmetrically arranged in each set, located on both sides directly below the paint spray frame 14. The two sets of pad rollers 2 alternately support the aluminum foil / aluminum strip 10, avoiding the defect that the two pad rollers 2 of one set are completely away from the aluminum foil / aluminum strip 10, and there is no support below the paint spraying position of the aluminum foil / aluminum strip 10.
[0025] After the pad roller 2 is completely away from the aluminum foil / aluminum strip 10, the first electric push rod 33 first lowers the pad roller 2 with the support plate 31 until the pad roller 2 moves laterally again and can no longer contact the bottom of the aluminum foil / aluminum strip 10. At this time, the second electric push rod 35 moves the pad roller 2 laterally below the aluminum foil / aluminum strip 10. Then, the first electric push rod 33 raises the support plate 31 and the pad roller 2 to contact the bottom edge of the aluminum foil / aluminum strip 10 (reset), forming a circular motion path (e.g., Figure 5 and Figure 6 (As shown).
[0026] As a further embodiment, the inner wall of the pad roller 2 is provided with a cavity, and a suction sleeve 37 is fixedly connected to one side of the slider 34. The suction sleeve 37 is coaxial with the pad roller 2. The conical surface of the pad roller 2 is uniformly provided with annular grooves 38, and the pad roller 2 is uniformly provided with suction holes 39. The suction holes 39 serve to adsorb and suck up excess atomized paint liquid. The suction holes 39 are uniformly provided at the bottom of the annular grooves 38. A scraper 4 is fixedly connected to one side of the slider 34. The scraper 4 is provided corresponding to the pad roller 2 and scrapes off the paint adhering to the cleaning pad roller 2.
[0027] On the one hand, the annular groove 38 provides friction when the two pad rollers 2 move away from each other at an angle and upward. Combined with the adsorption of the suction hole 39, it applies opposite tension on both sides of the aluminum foil / aluminum strip 10, so that the aluminum foil / aluminum strip 10 is flat and unfolded, avoiding the influence of wrinkles on the spraying. At the same time, it corrects the conveying of the aluminum foil / aluminum strip 10. On the other hand, it works with the pad roller 2 to play a correction role (when the laser offset sensor detects the offset of the aluminum foil / aluminum strip 10, it increases the suction force on one side). Moreover, the conical structure of the annular groove 38 for the pad roller 2 helps to slow down the flow of the enriched paint to the edge of the aluminum foil / aluminum strip 10, making it easier for the paint to be extracted.
