Description

Technical Field

[0001] The present invention relates to the field of spraying technology, in particular to a painting device for aluminum foil composite processing. Background Art

[0002] Aluminum foil composite processing refers to the process of combining aluminum foil with one or more other materials (such as plastic film, paper, metal foil, fabric, etc.) through physical or chemical methods to form a new composite material with comprehensive properties. Before the composite processing, it is necessary to spray a functional coating (such as paint, adhesive, inorganic oxide) on the surface of the aluminum foil and then composite it with other materials. Therefore, a paint spraying device is required for painting.

[0003] In the prior art, when spraying paint on aluminum foil, since the nozzles are generally fixed on a support plate and the distance between the nozzles is the same when fixed, part of the surface of the aluminum foil is between the nozzles during the spraying process. This results in many areas on the surface of the aluminum foil between the nozzles not being sprayed with paint, or less paint being sprayed, resulting in uneven spraying and affecting the spraying quality. In addition, after spraying the aluminum foil, the spraying effect cannot be detected, resulting in the inability to know the quality of the spraying effect, thereby affecting subsequent processing.

[0004] In addition, when spraying paint on aluminum foil, the aluminum foil is transported by conveyor rollers, and the aluminum foil is not stretched during transportation, resulting in low adhesion of the paint film when covering the aluminum foil, thus affecting the spraying quality.

[0033] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0034] like Figures 1-11 The painting device for aluminum foil composite processing shown in the figure includes a device shell 1, and the inner wall of the device shell 1 is provided with a stretching heating mechanism, a spraying adjustment mechanism and a spraying quality detection mechanism; the spraying adjustment mechanism includes L-shaped rods 19 symmetrically fixedly connected to both sides of the inner wall of the device shell 1, and a diversion box 6 is fixedly connected between the four L-shaped rods 19. The middle part of the top of the diversion box 6 is rotatably connected to a rotating shaft 27, and the top of the diversion box 6 corresponds to the outer side of the rotating shaft 27. A plurality of support columns 29 are fixedly connected to the top of the plurality of support columns 29 and are respectively fixedly connected to a square tube 7 and a circular hollow disk 28 and are connected. The outer wall of the rotating shaft 27 corresponds to the inside of the circular hollow disk 28 and is fixedly connected to a plurality of arc-shaped fan blades 36. When the paint flows and acts on the arc-shaped fan blades 36, a driving force is generated to rotate the rotating shaft 27, and the rotating shaft 27 rotates through the circular hollow disk 28; the spraying quality detection mechanism and the spraying adjustment mechanism operate synchronously, and the spraying of the aluminum foil body 4 is completed by the spraying adjustment mechanism, and then the spraying effect is quality-detected by the spraying quality detection mechanism.

[0035] like Figure 2 、 Figure 7 、 Figure 9 As shown, the spray adjustment mechanism also includes a reciprocating plate 34 slidably connected to the bottom end of the diverter box 6. A plurality of nozzles 43 are fixedly penetrated at the bottom end of the reciprocating plate 34. A connecting plate 18 is fixedly connected to one end of the reciprocating plate 34.

The other end of the return spring 13 is fixedly connected to a circular block 12. The circular block 12 is fixedly connected to the guide column 17. The reciprocating plate 34 is limited by the diverter box 6. Since the connecting plate 18 and the reciprocating plate 34 are fixedly connected, the reciprocating plate 34 is moved back and forth by the connecting plate 18, thereby changing the spray range and avoiding uneven spraying. The guide column 17 is limited by the vertical plate 16. At the same time, the guide column 17 is slidably connected to the top of the diverter box 6 through the slide plate, so that the guide column 17 can reciprocate stably.

[0036] like Figure 2 、 Figure 4As shown, the other end of the guide column 17 is fixedly connected to a fixing frame 26, and the inner wall of the fixing frame 26 is rotatably connected to a guide wheel 25. One side of the outer wall of the guide column 17 is slidably connected to the diverter box 6. The top of the outer wall of the rotating shaft 27 is fixedly connected to the special-shaped turntable 9. The guide wheel 25 contacts the outer wall of the special-shaped turntable 9. When the special-shaped turntable 9 rotates, the guide wheel 25 rolls along the outer wall of the special-shaped turntable 9, thereby causing the guide column 17 to reciprocate. L-shaped rods 19 are symmetrically fixedly connected to both ends of the diverter box 6. The four L-shaped rods 19 are fixedly connected to the device housing 1. The diverter box 6 is fixed to the inner wall of the device housing 1 through the L-shaped rods 19.

[0037] like Figure 1 、 Figure 2 As shown, the spray adjustment mechanism also includes a paint box 3 fixedly connected to one end of the outer side of the device housing 1. A paint pump 2 is fixedly connected to the top of the paint box 3. The paint pump 2 and the paint box 3 are connected by a pipe. The paint pump 2 and the square tube 7 are connected by a pipe 8. The square tube 7 and the diversion box 6 are also connected by a pipe. The paint in the paint box 3 is pumped out by the paint pump 2 and transported into the square tube 7 through the pipe and pipe 8. The paint then flows into the diversion box 6 through the pipe to facilitate subsequent spraying.

[0038] like Figure 2 、 Figure 8 、 Figure 11 As shown, the spraying quality detection mechanism includes a movable sleeve 11 fixedly connected to the inner wall of the device housing 1, the inner wall of the movable sleeve 11 is rotatably connected to a reciprocating screw rod 15, the outer wall of the reciprocating screw rod 15 is threadedly connected to a movable block 40, the bottom end of the movable block 40 is fixedly connected to a visual detector 39, and a transmission shaft 41 is rotatably passed through the top end of the movable sleeve 11. The transmission shaft 41 and the reciprocating screw rod 15 are connected by a bevel gear transmission mechanism 14, and the transmission shaft 41 and the rotating shaft 27 are connected by a chain transmission mechanism 10. The chain transmission mechanism 10 can make the rotating shaft 27 rotate with the transmission shaft 41, and the transmission shaft 41 rotates with the reciprocating screw 15 through the bevel gear transmission mechanism 14, and the moving block 40 and the moving sleeve 11 are square, so the moving sleeve 11 can limit the moving block 40, and the moving block 40 can be moved back and forth by the thread on the reciprocating screw 15. The moving block 40 moves back and forth with the visual detector 39 to perform quality inspection on the surface of the aluminum foil body 4 after spraying, so that the spraying quality can be known to prevent affecting subsequent processing, and the setting of the power source can also be reduced, further reducing the equipment cost.

[0039] like Figure 2 、 Figure 7 、 Figure 8As shown, the stretching and heating mechanism includes transverse columns 23 fixedly connected to the inner wall of the device housing 1 on both sides of the L-shaped rod 19. Two sets of transverse columns 23 are fixedly connected to the ends close to each other, and the inner walls of the two sets of fixing sleeves 24 are provided with telescopic columns 22. Transverse plates 21 are fixedly connected to the inner wall of the device housing 1 above the corresponding transverse columns 23. The bottom ends of the two sets of transverse plates 21 are fixedly connected to electric push rods 20. The telescopic ends of the two sets of electric push rods 20 are respectively fixedly connected to the two sets of telescopic columns 22. The transverse columns 23 and transverse plates 21 provide support for the fixing sleeves 24 and electric push rods 20, so that they are firmly fixed to the inner wall of the device housing 1.

[0040] like Figure 7 、 Figure 8 As shown, the two groups of fixed sleeves 24 are respectively rotated through by a driving shaft A33 and a driving shaft B38, the outer wall of the driving shaft A33 is fixedly connected to a squeezing roller B30, the outer wall of the driving shaft B38 is fixedly connected to a heating roller 31, one end of the fixed sleeve 24 on one side is respectively fixedly connected to a first motor 32 and a second motor 44, the driving ends of the first motor 32 and the second motor 44 are respectively fixedly connected to the driving shaft A33 and the driving shaft B38, the two groups of telescopic columns 22 are respectively rotated through by a driven shaft A35 and a driven shaft B42, the outer wall of the driven shaft A35 is fixedly connected to a squeezing roller A5, the squeezing roller A5 and the squeezing roller B30 squeeze the aluminum foil body 4, the smoothing roller 37 is fixedly connected between the driven shaft B42, the smoothing roller 37 and the heating roller 31 squeeze the aluminum foil body 4 and heat and dry it at the same time. One side of the aluminum foil body 4 is squeezed and clamped by the squeezing roller A5 and the squeezing roller B30, and the other side of the aluminum foil body 4 can be squeezed and clamped by the heating roller 31 and the smoothing roller 37. Since the speed and torque of the second motor 44 are greater than the speed and torque of the first motor 32, when the heating roller 31 and the squeezing roller B30 convey the aluminum foil body 4, the side with greater torque will cause stretching to the aluminum foil body 4, and the stretched aluminum foil body 4 will produce micro-undulations on the surface due to plastic deformation, increasing the surface roughness, thereby improving the adhesion of the paint film and improving the spraying quality, and the power roller is arranged on the lower surface of the aluminum foil body 4, so the upper surface of the aluminum foil body 4 will not be damaged during stretching, so the quality of painting can be guaranteed, and after painting, the upper surface of the sprayed aluminum foil body 4 can be rolled and smoothed by the smoothing roller 37 to prevent uneven spraying thickness.

[0041] Working principle: First, the aluminum foil body 4 is passed around the conveying roller and passed between the squeezing roller A5 and the squeezing roller B30 and between the heating roller 31 and the smoothing roller 37. At this time, the electric push rods 20 on both sides are controlled by the synchronous controller to move downward synchronously, and push the telescopic column 22 downward, so that the driven shaft A35 and the squeezing roller A5 can be moved downward, and the squeezing roller B30 can be used to squeeze and clamp one side of the aluminum foil body 4. Similarly, the driven shaft B42 and the smoothing roller 37 can be moved downward, and the heating roller 31 can be used to squeeze and clamp the other side of the aluminum foil body 4. At this time, the electric push rods 20 on both sides are controlled by the synchronous controller to move downward synchronously, and push the telescopic column 22 downward, so that the driven shaft A35 and the squeezing roller A5 can be moved downward, and the squeezing roller B30 can be used to squeeze and clamp the other side of the aluminum foil body 4. The first motor 32 and the second motor 44, and the torque of the second motor 44 is greater than the torque of the first motor 32, resulting in the torque of the heating roller 31 being greater than the torque of the squeezing roller B30. Therefore, a stretching process is generated on the aluminum foil body 4 between the heating roller 31 and the squeezing roller B30. Therefore, the surface of the aluminum foil body 4 in the area to be sprayed can be deformed to produce micro-undulations, thereby increasing the surface roughness, thereby improving the adhesion of the paint film and ensuring the spraying quality. After spraying, the aluminum foil body 4 is heated by the heating roller 31 and the smoothing roller 37. Through heat transfer, it can be heated and dried after spraying, thereby ensuring the spraying effect.

[0042] During the stretching process, the paint pump 2 is started to transport the paint in the paint box 3 to the square tube 7 through the pipe and the pipeline 8. At this time, the paint flow is sprayed on the arc-shaped fan blade 36, and the arc-shaped fan blade 36 rotates around the center line of the rotating shaft 27, and the rotating shaft 27 rotates with the special-shaped turntable 9. Since the guide wheel 25 and the special-shaped turntable 9 are in contact with each other, when the special-shaped turntable 9 rotates, the guide wheel 25 rolls along the outer wall of the special-shaped turntable 9. At the same time, due to the cooperation of the circular block 12, the return spring 13 and the vertical plate 16, the fixing frame 26 and the guide wheel 25 can be adjusted. The guide column 17 moves back and forth, and the guide column 17 moves back and forth with the connecting plate 18 and the reciprocating plate 34. Since the nozzle 43 is fixed and penetrates the reciprocating plate 34, the spraying range of the nozzle 43 can be changed. At the same time, the paint enters the diverter box 6 through the pipe and is sprayed out through the nozzle 43, avoiding the situation where the outer surface of the aluminum foil is not sprayed with paint or less paint is sprayed during spraying, resulting in uneven spraying and affecting the spraying quality. In addition, the setting of the power source can be reduced during use, thereby reducing the equipment cost.

[0043] And in the spraying process, the rotating shaft 27 rotates through the chain transmission mechanism 10 with the transmission shaft 41, and the transmission shaft 41 rotates through the bevel gear transmission mechanism 14 with the reciprocating screw rod 15, and the moving block 40 and the moving sleeve 11 are square, so that the moving sleeve 11 can limit the moving block 40, and the moving block 40 can reciprocate through the thread on the reciprocating screw rod 15, and the moving block 40 reciprocates with the visual detector 39 to detect the quality of the surface of the aluminum foil body 4 after spraying, so that the spraying quality can be known, and the subsequent processing is prevented from being affected, and the power source can also be reduced, further reducing the equipment cost, and when the spraying quality is not up to standard, the subsequent processing mechanism can be used to trim the non-standard part, ensuring that the overall quality meets the standard.
