Description

Technical Field

[0001] This invention relates to equipment for processing aluminum curtain wall panels, and more specifically, to surface processing equipment and processing technology for UV-resistant aluminum curtain wall panels. Background Technology

[0002] Some building curtain walls are made of spliced ​​aluminum panels, with adjacent curtain walls joined together by corner aluminum panels. Since the curtain walls are directly installed outdoors, UV-resistant aluminum curtain wall panels are currently a commonly used material for building facades. The surface of this type of curtain wall aluminum panel is generally coated with a UV-resistant coating and a transparent protective layer. Currently, this coating is applied to the surface of the aluminum panel by spraying or roller coating. However, this method is only suitable for surface processing of flat aluminum panels. For corner aluminum panels, because their surface is curved, only spraying can be used. However, spraying not only has the disadvantage of uneven surface coating, but also wastes a lot of paint. Therefore, there is an urgent need to improve this method. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a surface processing equipment and process for UV-resistant aluminum curtain wall panels. By placing the corner aluminum panel on a feeding mechanism and rotating the feeding mechanism and the coating roller, the curved surface of the corner aluminum panel can be coated by roller coating, thereby realizing the roller coating process on the surface of the corner aluminum panel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a surface processing device for UV-resistant curtain wall aluminum panels, used for processing corner aluminum panels, including a roller coating device. The roller coating device includes a frame, a material trough is provided inside the frame, a coating roller is provided inside the material trough, and a feeding mechanism is provided above the coating roller. The feeding mechanism includes a feeding roller and a transfer plate installed on the surface of the feeding roller. The transfer plate is separable from the feeding mechanism. There are two transfer plates, which are symmetrically arranged along the axis of the feeding roller. The corner aluminum panel is inserted into the surface of the transfer plate. The feeding roller is rotated so that the arc-shaped surface of the corner aluminum panel can contact the coating roller. The rotation direction of the coating roller and the feeding roller is the same, and the axis of the arc-shaped surface of the corner aluminum panel coincides with the axis of the feeding roller.

[0005] Furthermore, within the frame, a first scraper roller, a second scraper roller, a pressure roller, and a cleaning roller are sequentially arranged along the rotation direction of the feeding roller. The first scraper roller and the second scraper roller are located on the same side of the feeding mechanism, and the pressure roller and the cleaning roller are located on the other side of the feeding mechanism. The pressure roller is positioned higher than the cleaning roller.

[0006] Furthermore, the gap between the surface of the first scraper roller and the surface of the feeding roller is greater than the gap between the surface of the second scraper roller and the surface of the feeding roller, and the rotation direction of the first scraper roller and the second scraper roller is the same as that of the feeding roller.

[0007] Furthermore, the diameter of the feeding roller is smaller than the diameter of the arc-shaped surface, the surface of the pressure roller has a pattern, the pressure roller can abut against the arc-shaped surface, there is a gap between the surface of the pressure roller and the surface of the feeding roller, and the surface of the cleaning roller abuts against the surface of the feeding mechanism.

[0008] Furthermore, the surface of the feeding roller is provided with a first mounting groove, and the bottom of the first mounting groove is provided with a limiting groove. The first mounting groove and the limiting groove are respectively connected to both ends of the feeding roller. The transfer plate is installed in the first mounting groove. The transfer plate includes a limiting rib. The limiting rib can be inserted into the limiting groove for limiting. The transfer plate can be inserted from one end of the first mounting groove and pulled out from the other end.

[0009] Furthermore, the feeding roller and the transfer plate are limited by a limiting mechanism. The bottom of the first mounting groove is provided with a second mounting groove. The limiting mechanism is installed in the second mounting groove. The limiting mechanism includes a limiting member, a cover plate, and a spring. The limiting member includes a protrusion, a limiting platform, and a guide rib. The cover plate covers the second mounting groove. The protrusion penetrates the cover plate. The limiting platform can abut against or detach from the cover plate. The lower end of the guide rib is inserted into the guide groove at the bottom of the second mounting groove. The spring is sleeved on the outside of the guide rib. The upper end of the spring abuts against the lower part of the limiting platform and the lower end abuts against the bottom of the second mounting groove. The lower part of the transfer plate is provided with an arc-shaped groove corresponding to the protrusion. The surface of the protrusion is arc-shaped. The protrusion can insert into or detach from the arc-shaped groove.

[0010] Furthermore, the outer surface of the transfer plate is provided with a first clearance groove adapted to the arc-shaped surface, and a second clearance groove is provided on both sides of the first clearance groove. One side of the second clearance groove is open, and the corner aluminum plate can be inserted from the opening on the side of the second clearance groove so that the arc-shaped surface is inserted into the first clearance groove. The inserts located on both sides of the arc-shaped surface are respectively inserted into the two second clearance grooves for limitation. The outer surfaces on both sides of the transfer plate are provided with transition surfaces that are inclined toward the surface of the feeding roller.

[0011] Furthermore, it also includes a transfer mechanism, a conveyor belt, and an oven. The transfer mechanism is directly opposite the roller coating device, the conveyor belt is located between the roller coating device and the transfer mechanism, and the conveyor belt passes through the oven.

[0012] Furthermore, the transfer mechanism includes a jaw, a pressure plate, a first driver, a second driver, and a third driver. The first driver can drive the pressure plate to move up and down so that the jaw can clamp the transfer plate. The second driver can drive the jaw to move horizontally to transfer the transfer plate from the feeding roller to above the conveyor belt. The third driver can drive the jaw to move up and down to place the transfer plate on the surface of the conveyor belt.

[0013] A surface processing technology for UV-resistant aluminum curtain wall panels includes the following steps:

[0014] S1. Insert the corner aluminum plate into the transfer plate;

[0015] S2. Rotate the feeding roller so that the first mounting groove on one side of the feeding roller faces upward, and insert the transfer plate with the corner aluminum plate installed into the first mounting groove above.

[0016] S3. Rotate the feeding roller. After the corner aluminum plate passes the pressure roller, the pressure roller will press a pattern onto the arc-shaped surface of the corner aluminum plate.

[0017] S4. After the corner aluminum plate passes through the coating roller, the coating is transferred to the curved surface of the corner aluminum plate by the coating roller.

[0018] S5. After the corner aluminum plate passes through the first scraper and the second scraper, the excess paint on the arc surface is scraped off by the first scraper and the second scraper, and the scraped paint re-enters the material tank.

[0019] S6. When the coated corner aluminum plate is located above, the corner aluminum plate and the transfer plate are transferred from the feeding roller to the conveyor belt by the transfer mechanism.

[0020] S7. The transfer plate with the corner aluminum plate is conveyed into the drying oven by the conveyor belt to dry the coating.

[0021] In step S6, when the transfer plate is removed from the feed roller, step S2 is repeated.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. During the rotation of the feeding roller and coating roller, when the arc-shaped surface of the corner aluminum plate contacts the coating roller, the coating material on the coating roller surface can be transferred to the arc-shaped surface, realizing roller coating on the arc-shaped surface. When the arc-shaped surface with coating material rotates to the first scraper roller, a portion of the coating material on the arc-shaped surface is scraped off by the first scraper roller, thereby leveling the coating material. When it rotates to the second scraper roller, the coating material on the arc-shaped surface is processed again by the second scraper roller, thereby effectively improving the flatness and uniformity of the coating material on the arc-shaped surface. Furthermore, the coating material scraped off by the first and second scraper rollers re-enters the material trough, effectively reducing coating material waste.

[0024] 2. The roller coating device not only enables the application of an anti-UV coating to the curved surface of corner aluminum plates, thus achieving chemical UV blocking, but also allows for the molding of fine concave-convex structures on the curved surface. By altering the interaction mechanism between light and the concave-convex surface, physical UV blocking is achieved, significantly improving the UV resistance. Furthermore, roller coating after molding greatly enhances the bonding between the coating and the curved surface, reducing the probability of coating peeling off during prolonged outdoor use. Even if the anti-UV coating peels off during extended use, the concave-convex structure on the surface still provides UV protection, thereby significantly improving the performance of the corner aluminum plate.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, this embodiment discloses a surface processing equipment for UV-resistant curtain wall aluminum panels, used to process corner aluminum panels 9. The corner aluminum panel 9 includes a quarter-circle arc surface 91, and inserts 92 are provided on both sides of the arc surface 91. The inserts 92 are used to connect two flat aluminum panels. The shape of the corner aluminum panel 9 is formed by stamping. The arc surface 91 of the corner aluminum panel 91 is coated with a UV-resistant coating by a roller coating device 1.

[0036] The roller coating device 1 includes a frame 11, a material trough 12 is provided inside the frame 11, the material trough 12 is filled with anti-ultraviolet coating, a discharge port 14 is provided at the bottom of the material trough 12, and a coating roller 13 is provided inside the material trough 12. The coating roller 13 is partially immersed in the coating. When the coating roller 13 is rotated, the coating can adhere to the surface of the coating roller 13. The driver that drives the coating roller 13 to rotate is prior art, so it will not be described in detail in this specification.

[0037] like Figure 3As shown, a feeding mechanism 100 is provided above the coating roller 13. The feeding mechanism 100 includes a feeding roller 2 and a transfer plate 3 mounted on the surface of the feeding roller 2. There are two transfer plates 3, symmetrically arranged along the axis of the feeding roller 2. A corner aluminum plate 9 is inserted into the surface of the transfer plate 3. The axis of the arc-shaped surface 91 of the corner aluminum plate 9 coincides with the axis of the feeding roller 2. The feeding roller 2 can rotate intermittently to drive the transfer plate 3 and the corner aluminum plate 9 located on the surface of the transfer plate 3 to rotate, so that the arc-shaped surface 91 of the corner aluminum plate 9 can contact the coating roller 13. The coating roller 13 and the feeding roller 2 rotate in the same direction. Figure 3 For example, the pointer rotates clockwise, and the driver that drives the feeding roller 2 to rotate is existing technology, so it will not be described in detail in this specification.

[0038] During the rotation of the feeding roller 2 and the coating roller 13, when the arc-shaped surface 91 of the corner aluminum plate 9 comes into contact with the coating roller 13, the coating material on the surface of the coating roller 13 can be transferred to the surface of the arc-shaped surface 91, thereby realizing roller coating on the surface of the arc-shaped surface 91.

[0039] Within the frame 11, a first scraper roller 15 and a second scraper roller 16 are sequentially arranged along the rotation direction of the feeding roller 2. The first scraper roller 15 and the second scraper roller 16 are located on the same side of the feeding mechanism 100. The gap between the first scraper roller 15 and the surface of the feeding roller 2 is larger than the gap between the second scraper roller 16 and the surface of the feeding roller 2. The first scraper roller 15 and the second scraper roller 16 rotate in the same direction as the feeding roller 2. Both the first scraper roller 15 and the second scraper roller 16 are high-speed rotating wire rods. When the arc-shaped surface 91 with paint rotates to the first scraper roller 15, a portion of the paint on the surface of the arc-shaped surface 91 is scraped off by the first scraper roller 15, thereby leveling the paint. When it rotates to the second scraper roller 16, the paint on the surface of the arc-shaped surface 91 is processed again by the second scraper roller 16, thereby effectively improving the flatness and uniformity of the paint on the surface of the arc-shaped surface 91. Furthermore, the paint scraped off by the first scraper roller 15 and the second scraper roller 16 re-enters the material trough 12, effectively reducing paint waste.

[0040] After the second scraper roller 16, a pressure roller 4 and a cleaning roller 17 are also provided, and the pressure roller 4 and the cleaning roller 17 are located on the other side of the feeding mechanism 100.

[0041] The pressure roller 4 is positioned higher than the cleaning roller 17. The diameter of the feeding roller 2 is smaller than the diameter of the arc-shaped surface 91. The outer surfaces of both sides of the transfer plate 3 are provided with transition surfaces 35 that are inclined towards the surface of the feeding roller 2. The transition surfaces 35 can reduce the residue of coating on the surface of the feeding mechanism 100. The surface of the pressure roller 4 has a pattern. The pressure roller 4 can abut against the arc-shaped surface 91. There is a gap between the surface of the pressure roller 4 and the surface of the feeding roller 2, that is, the surfaces of the pressure roller 4 and the feeding roller 2 do not contact each other. The pattern on the surface of the pressure roller 4 is a micron-level concave-convex pattern, which can be random pits, regular polygons, etc. The pattern depth is between 30 microns and 40 microns. After the corner aluminum plate 9 is installed on the feeding mechanism 100, the feeding roller 2 first rotates the corner aluminum plate 9 through the pressure roller 4. Through the pressure roller 4, the surface of the arc-shaped surface 91 is molded into a concave-convex shape, and because of the concave... Because the convex shape is relatively deep, the surface of the arc-shaped surface 91 still has an uneven shape after coating. Therefore, in this embodiment, the roller coating device 1 can not only achieve the roller coating of the anti-ultraviolet coating on the arc-shaped surface 91 of the corner aluminum plate 9, thereby achieving chemical blocking of ultraviolet rays, but also mold a fine uneven structure on the arc-shaped surface 91 of the corner aluminum plate 9. By changing the interaction mechanism between light and the uneven surface, physical blocking of ultraviolet rays is achieved, which greatly improves the anti-ultraviolet effect. Furthermore, roller coating after molding can also greatly improve the bonding effect between the coating and the surface of the arc-shaped surface 91, reducing the probability of coating peeling off during long-term outdoor use. Even if the anti-ultraviolet coating peels off during long-term use, the uneven structure on its surface can still play an anti-ultraviolet role, thereby greatly improving the performance of the corner aluminum plate 9.

[0042] The surface of the cleaning roller 17 abuts against the surface of the feeding mechanism 100. Specifically, the cleaning roller 17 is a rubber roller or a sponge roller, preferably a sponge roller. The cleaning roller 17 can contact the portion of the feeding roller 2 and the transfer plate 3 exposed on the corner aluminum plate 9, as well as the surface of the corner aluminum plate 9. The cleaning roller 17 can clean the feeding mechanism 100, which is beneficial to the roll coating of the corner aluminum plate 9.

[0043] Furthermore, the first scraper roller 15, the second scraper roller 16, the pressure roller 4, the cleaning roller 17, and the coating roller 13 are distributed around the feed roller 2. The lengths of the first scraper roller 15, the second scraper roller 16, the pressure roller 4, the cleaning roller 17, and the coating roller 13 are all longer than the length of the feeding mechanism 100. Through the above design, the integrated design of molding and roller coating on the arc surface 91 of the corner aluminum plate 9 can be realized, which is beneficial to improving the processing efficiency of the surface of the corner aluminum plate 9.

[0044] like Figure 5 and Figure 6As shown, the outer surface of the transfer plate 3 is provided with a first clearance groove 31 adapted to the arc surface 91. Second clearance grooves 32 are provided on both sides of the first clearance groove 31. One side of the second clearance groove 32 is open, allowing the corner aluminum plate 9 to be inserted through the opening on the side of the second clearance groove 32, so that the arc surface 91 is inserted into the first clearance groove 31. The inserts 92 located on both sides of the arc surface 91 are respectively inserted into the two second clearance grooves 32 for positioning. This design facilitates the connection between the corner aluminum plate 9 and the transfer plate 3, and also facilitates the removal of the corner aluminum plate 9. When the corner aluminum plate 9 and the transfer plate 3... After assembly, one side of the corner aluminum plate 9 abuts against the side of the second clearance groove 32 away from its opening. Through the cooperation of the insert 92 and the second clearance groove 32, the corner aluminum plate 9 can only be pulled out from one end. Since the cooperation length between the corner aluminum plate 9 and the transfer plate 3 is relatively long, the corner aluminum plate 9 will not detach from the transfer plate 3 even when the feeding roller 2 is rotating. Even if the corner aluminum plate 9 is slightly loose, since the lengths of the first scraper roller 15, the second scraper roller 16, the pressure roller 4, the cleaning roller 17 and the coating roller 13 are all longer than the length of the feeding mechanism 100, the processing operation on the surface of the corner aluminum plate 9 will not be affected.

[0045] like Figures 2-4 and Figure 6 As shown, the transfer plate 3 can be separated from the feeding mechanism 100. Specifically, the surface of the feeding roller 2 is provided with a first mounting groove 21, and the bottom of the first mounting groove 21 is provided with a limiting groove 22. The limiting groove 22 is a dovetail groove. The first mounting groove 21 and the limiting groove 22 are respectively connected to both ends of the feeding roller 2. The transfer plate 3 is installed in the first mounting groove 21. The transfer plate 3 includes a limiting rib 33. The limiting rib 33 can be inserted into the limiting groove 22 for limiting. The limiting rib 33 is adapted to the limiting groove 22. The transfer plate 3 can be inserted from one end of the first mounting groove 21 and pulled out from the other end. It can be seen that the transfer plate 3 is a side-insertion design, which can be inserted or pulled out from both sides. This design facilitates the assembly and disassembly of the transfer plate 3.

[0046] like Figure 4As shown, in order to achieve the installation and positioning of the transfer plate 3 and prevent the transfer plate 3 from sliding during the rotation of the feeding roller 2, the feeding roller 2 and the transfer plate 3 need to be limited by the limiting mechanism 5. The bottom of the first mounting groove 21 is provided with a second mounting groove 23, and the limiting mechanism 5 is installed in the second mounting groove 23. The limiting mechanism 5 includes a limiting member 51, a cover plate 52 and a spring 53. The limiting member 51 includes a protrusion 511, a limiting platform 512 and a guide rib 513. The cover plate 52 covers the second mounting groove 23. The protrusion 511 penetrates the cover plate 52, the limiting platform 512 can abut against or detach from the cover plate 52, the lower end of the guide rib 513 is inserted into the guide groove at the bottom of the second mounting groove 23, the spring 53 is sleeved on the outside of the guide rib 513, the upper end of the spring 53 abuts against the lower part of the limiting platform 512 and the lower end abuts against the bottom of the second mounting groove 23, the lower part of the transfer plate 3 is provided with an arc-shaped groove 34 corresponding to the protrusion 511, the surface of the protrusion 511 is arc-shaped, and the protrusion 511 can be inserted into or detached from the arc-shaped groove 34;

[0047] During the process of inserting the transfer plate 3 into the first mounting groove 21, when the arc-shaped groove 34 moves to the limiting member 51, the limiting member 51 springs upward under the action of the spring 53, so that the protrusion 511 is inserted into the arc-shaped groove 34, thereby limiting and positioning the transfer plate 3, thus preventing the transfer plate 3 from deviating during the rotation of the feeding roller 2; since the surface of the protrusion 511 is also arc-shaped, and the height of the protrusion 511 inserted into the arc-shaped groove 34 is smaller than the radius of the arc-shaped groove 34 and the radius of the protrusion 511, when it is necessary to remove the transfer plate 3, it is only necessary to push or pull the transfer plate 3, and the limiting member 51 can pass over the arc-shaped groove 34, thereby realizing the disassembly of the transfer plate 3.

[0048] like Figure 1 As shown, this embodiment also includes a transfer mechanism 6, a conveyor belt 7, and an oven 8. The transfer mechanism 6 is directly opposite the roller coating device 1. The conveyor belt 7 is located between the roller coating device 1 and the transfer mechanism 6. The conveyor belt 7 passes through the oven 8. The transfer mechanism 6 is used to transfer the transfer plate 3 from the feeding roller 2 onto the conveyor belt 7, and to convey the transfer plate 3 with the corner aluminum plate 9 through the conveyor belt 7, and to convey the transfer plate 3 through the oven 8, where the coating on the surface of the corner aluminum plate 9 is dried. The conveyor belt 7 and the oven 8 are both existing technologies, and their specific structures will not be described in detail in this specification.

[0049] like Figure 1 and Figure 7As shown, the transfer mechanism 6 includes a jaw 61, a pressure plate 62, a first driver 63, a second driver 64, and a third driver 65. The first driver 63 can drive the pressure plate 62 to move up and down so that the jaw 61 can clamp the transfer plate 3. The second driver 64 can drive the jaw 61 to move horizontally to transfer the transfer plate 3 from the feeding roller 2 to the top of the conveyor belt 7. The third driver 65 can drive the jaw 61 to move up and down to place the transfer plate 3 on the surface of the conveyor belt 7.

[0050] The first driver 63, the second driver 64, and the third driver 65 are all hydraulic cylinders. The third driver 65 is fixed to the side of the conveyor belt 7. The end of the telescopic rod of the third driver 65 is fixed with a second support plate 66. The second driver 65 is fixedly connected to the second support plate 66. The gripper 61 includes a first support surface 611, a second support surface 612, and a connecting plate 613 connecting the first support surface 611 and the second support surface 612. The telescopic rod of the second driver 64 is fixedly connected to the connecting plate 613. The first driver 63 is installed on the upper part of the first support surface 611. The second support surface 612 and the pressure plate 62 form a clamping structure. This clamping structure can clamp the transfer plate 3. The transfer plate 3 has protrusions 36 at both ends. One protrusion 36 faces the transfer mechanism 6. The clamping structure can clamp the protrusion 36 facing the transfer mechanism 6 and pull the transfer plate 3 out from the feeding roller 2 through the second driver 64.

[0051] The frame 11 is also provided with a first support plate 18 on the side facing the transfer mechanism 6. The height of the first support plate 18 is slightly lower than the height of the transfer plate 3 when it is above the feeding roller 2. Through the first support plate 18, the transfer mechanism 6 provides a certain support for the transfer plate 3 when it is pulled out.

[0052] One surface processing technology for UV-resistant aluminum curtain wall panels includes the following steps:

[0053] S1. Insert the corner aluminum plate 9 into the transfer plate 3;

[0054] S2. Rotate the feeding roller 2 so that the first mounting groove 21 on one side of the feeding roller 2 faces upward, and insert the transfer plate 3 with the corner aluminum plate 9 installed into the first mounting groove 21 above.

[0055] S3. Rotate the feeding roller 2. After the corner aluminum plate 9 passes the pressure roller 4, the pressure roller 4 presses a pattern onto the arc-shaped surface 91 of the corner aluminum plate 9.

[0056] S4. After the corner aluminum plate 9 passes through the coating roller 13, the coating is transferred to the surface of the arc-shaped surface 91 of the corner aluminum plate 9 by the coating roller 13.

[0057] S5. After the corner aluminum plate 9 passes the first scraper roller 15 and the second scraper roller 16, the excess paint on the surface of the arc surface 91 is scraped off by the first scraper roller 15 and the second scraper roller 16, and the scraped paint re-enters the material tank 12.

[0058] S6. When the coated corner aluminum plate 9 is located above, the corner aluminum plate 9 and the transfer plate 3 are transferred from the feeding roller 2 to the conveyor belt 7 by the transfer mechanism 6.

[0059] S7. The transfer plate 3 with the corner aluminum plate 9 is conveyed into the drying oven 8 by the conveyor belt 7 to dry the coating.

[0060] In step S6, when the transfer plate 3 is removed from the feeding roller 2, step S2 is repeated. It can be seen that by setting the roller coating device 1, the roller coating of the corner aluminum plate 9 can be achieved.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
