Description

Technical Field

[0001] This utility model relates to the field of color-coated steel sheet processing technology, and more specifically, to a color-coated steel sheet coating correction device. Background Technology

[0002] Color-coated steel sheet, also known as color steel plate or color plate, is a sheet made of cold-rolled steel sheet and galvanized steel sheet as substrate. After surface pretreatment, paint is continuously applied, and the sheet is baked and cooled. During the coating process, the color-coated steel sheet may deviate. After coating, the surface pigment will be unevenly coated, and the coating work needs to be redone. This affects the processing efficiency and coating quality of the color-coated steel sheet, thus requiring the use of a color-coated steel sheet coating correction device.

[0003] A search revealed that Chinese patent CN214878921U discloses a coating correction device for color-coated steel sheets. This structure effectively prevents the steel sheets from shifting during coating, which is beneficial for improving the quality of color-coated steel sheets.

[0004] However, in actual use, this structure uses pulleys inside the limiting groove of the limiting block to guide the coating of the color-coated plate. However, the width of the limiting groove of the limiting block is fixed. When facing color-coated plates of different thicknesses, it is difficult to flexibly adjust the limiting distance, which makes it unable to adapt to plates of different thicknesses and affects the correction effect. In view of this, this utility model proposes a color-coated plate coating correction device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a color-coated steel plate coating correction device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a color-coated steel sheet coating correction device, comprising two support frames, each of which has a lifting frame on one side opposite to the other, and each of the two lifting frames has an adjustable guide structure on its top.

[0007] To better adapt to color-coated steel sheets of different thicknesses, preferably, the adjustable guide structure includes a concave block. Several side guide rollers are rotatably mounted on the inner wall of the concave block. Several rectangular grooves are formed at the bottom of the inner cavity of the concave block, and bottom guide rollers are rotatably mounted inside each of the rectangular grooves. An adjusting plate is movably mounted on the top of the inner cavity of the concave block. Several sets of support blocks are fixedly arranged at the bottom of the adjusting plate, with two support blocks in each set. A top guide roller is rotatably mounted between the two support blocks. An adjusting screw is connected to the top of the adjusting plate, and guide rods are provided on both sides of the adjusting screw. The adjusting screw is threadedly connected to the concave block, and one end of each guide rod is fixedly connected to the adjusting plate and slidably connected to the concave block.

[0008] In order to adjust the height of the concave block so that it is flush with the coating roller of the coating equipment, preferably, a first lead screw is fixedly installed inside each of the two support frames, a movable block is slidably installed on the outside of the first lead screw, one end of the lifting frame is welded to the outer wall of the movable block, and a limit nut is provided on the outside of the first lead screw and at the bottom of the movable block, and the limit nut is threadedly connected to the first lead screw.

[0009] In order to adjust the spacing between the two concave blocks according to the width of the color-coated sheet, preferably, two mounting seats are fixedly installed on the upper surface of the lifting frame, and a second lead screw is rotatably installed between the two mounting seats. The external thread of the second lead screw is engaged with a movable seat. The movable seat is fixedly installed on the bottom of the concave block. A rotating block is provided at one end of the second lead screw. The movable seat is slidably guided on the surface of the lifting frame through a guide groove.

[0010] To facilitate adjustment of the distance between the two support frames and ensure the overall compatibility of the device and equipment, preferably, a connecting plate is welded to one end of the outer wall of each of the two lifting frames. A sleeve rod is fixedly installed on the inner wall of one of the connecting plates, and a telescopic rod is fixedly installed on the inner wall of the other connecting plate. The telescopic rod is movably sleeved inside the sleeve rod.

[0011] To facilitate the installation of the support frame at the coating equipment, preferably, the bottom of both support frames is welded with mounting plates, and mounting holes are opened through both sides of the mounting plates.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting an adjustable guide structure, the device can flexibly adapt to color-coated plates of different thicknesses by using the cooperation of adjusting screws, guide rods and adjusting plates, thus expanding the applicability of the device. The side, bottom and top guide rollers work together to form an all-round guiding constraint during the coating process, ensuring the precise movement of the color-coated plates, effectively correcting deviations and improving coating quality and efficiency.

[0014] 2. By adjusting the lifting frame up and down, the lifting frame drives the movable block to slide up and down outside the first lead screw. This allows the concave block of the adjustable guide structure to be flush with the coating roller of the coating equipment according to the height of the coating equipment. By rotating the limit nut threaded to the bottom of the movable block and making it tightly fit against the bottom of the movable block, the movable block is limited, which can prevent the adjusted movable block from sliding outside the first lead screw and improve the use effect.

[0015] 3. By rotating the corresponding rotating block, the second lead screw rotates between the two mounting seats, which in turn causes the moving seat to slide and be guided on the surface of the lifting frame through the guide groove, and drives the concave block to move. In this way, the distance between the two concave blocks can be adjusted according to the width of the color-coated sheet, thereby improving the range of applications. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-4 The color-coated steel sheet coating correction device shown includes two support frames 1, each with a lifting frame 2 on its opposite side, and an adjustable guide structure on the top of each lifting frame 2.

[0023] The structure of this application will be explained in detail below:

[0024] In this embodiment, as shown in the appendix Figure 1 , 3As shown in Figure 4, the adjustable guide structure includes a concave block 3. Several side guide rollers 4 are rotatably mounted on the inner wall of the concave block 3. Several rectangular grooves 5 are opened at the bottom of the inner cavity of the concave block 3. Bottom guide rollers 6 are rotatably mounted inside each of the rectangular grooves 5. An adjusting plate 7 is movably mounted on the top of the inner cavity of the concave block 3. Several sets of support blocks 8 are fixedly set at the bottom of the adjusting plate 7. The number of support blocks 8 in each set is set to two, and a top guide roller 9 is rotatably mounted between the two support blocks 8. An adjusting screw 10 is connected to the top of the adjusting plate 7, and guide rods 11 are set on both sides of the adjusting screw 10. The adjusting screw 10 is threadedly connected to the concave block 3. One end of the guide rod 11 is fixedly connected to the adjusting plate 7, and the guide rod 11 is slidably connected to the concave block 3.

[0025] Specifically, in this structure, when the color-coated sheet is being coated and corrected, both ends of the color-coated sheet are located inside the corresponding concave frame and are attached to the outer wall of several side guide rollers 4, and the bottom surface of the color-coated sheet is attached to the surface of several bottom guide rollers 6.

[0026] Depending on the thickness of the color-coated sheet, the operator rotates the adjusting screw 10 to adjust the adjusting plate 7 up and down under the action of the two guide rods 11. Then, the distance between the concave frame and the adjusting plate 7 is adjusted according to the thickness of the color-coated sheet, so that several top guide rollers 9 are attached to the upper surface of the color-coated sheet, thus adapting to color-coated sheets of different thicknesses.

[0027] During the coating process of the color-coated steel sheet, several side guide rollers 4 rotate inside the concave block 3, several bottom guide rollers 6 rotate inside the corresponding rectangular groove 5, and several top guide rollers 9 rotate between the corresponding two support blocks 8 to guide the coating of the color-coated steel sheet, thereby achieving the purpose of correction and improving the application range.

[0028] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, a first lead screw 12 is fixedly installed inside both support frames 1, and a movable block 13 is slidably installed on the outside of the first lead screw 12. One end of the lifting frame 2 is welded to the outer wall of the movable block 13. A limit nut 14 is provided on the outside of the first lead screw 12 and at the bottom of the movable block 13. The limit nut 14 is threadedly connected to the first lead screw 12.

[0029] Specifically, in this structure, depending on the height of the coating equipment, the operator can adjust the lifting frame 2 in advance so that the lifting frame 2 drives the movable block 13 to slide up and down outside the first lead screw 12. Thus, depending on the height of the coating equipment, the concave block 3 of the adjustable guide structure can be flush with the coating roller of the coating equipment. The limiting nut 14 is screwed to the bottom of the movable block 13 and fits tightly against the bottom of the movable block 13 to limit the movable block 13 and prevent the adjusted movable block 13 from sliding outside the first lead screw 12.

[0030] In this embodiment, as shown in the appendix Figure 1 , 3 As shown, two mounting seats 15 are fixedly installed on the upper surface of the lifting frame 2, and a second lead screw 16 is rotatably installed between the two mounting seats 15. The external thread of the second lead screw 16 is engaged with a movable seat 17. The movable seat 17 is fixedly installed at the bottom of the concave block 3. A rotating block 18 is provided at one end of the second lead screw 16. The movable seat 17 is slidably guided on the surface of the lifting frame 2 through a guide groove.

[0031] Specifically, in this structure, depending on the width of the color-coated sheet, the operator rotates the corresponding rotating block 18, causing the second lead screw 16 to rotate between the two mounting seats 15. This causes the moving seat 17 to slide and be guided on the surface of the lifting frame 2 through the guide groove, and drives the concave block 3 to move. Thus, the distance between the two concave blocks 3 can be adjusted according to the width of the color-coated sheet, thereby increasing the range of use.

[0032] In this embodiment, as shown in the appendix Figure 1 As shown, a connecting plate 19 is welded to one end of the outer wall of each of the two lifting frames 2. A sleeve rod 20 is fixedly installed on the inner wall of one of the connecting plates 19, and a telescopic rod 21 is fixedly installed on the inner wall of the other connecting plate 19. The telescopic rod 21 is movably sleeved inside the sleeve rod 20.

[0033] Specifically, in this structure, the telescopic rod 21 slides inside the sleeve rod 20, which can adjust the distance between the two support frames 1 according to the width of the coating equipment.

[0034] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, mounting plates 22 are welded to the bottom of both support frames 1. Mounting holes 23 are opened through both sides of the mounting plates 22 for mounting the support frames 1 to the coating equipment.

[0035] Working principle of this utility model:

[0036] This application provides a color-coated steel sheet coating correction device. In actual use, first check that the device is in good condition and ensure that all structures have good fit and no jamming or other malfunctions.

[0037] The telescopic rod 21 slides inside the sleeve rod 20. The installation position between the two support frames 1 is determined according to the width of the coating equipment to ensure the overall compatibility of the device and the equipment. The support frames 1 are installed at the coating equipment by bolts through the mounting plates 22 welded to the bottom of the two support frames 1 and the mounting holes 23 opened through the two sides of the mounting plates 22. This provides a stable support foundation for the entire correction device and ensures that the device remains stable in subsequent work.

[0038] Depending on the height of the coating equipment, the operator adjusts the lifting frame 2 up and down, causing the lifting frame 2 to drive the movable block 13 to slide up and down outside the first lead screw 12, so that the concave block 3 in the adjustable guide structure at the top of the lifting frame 2 is flush with the coating roller of the coating equipment. After the adjustment is completed, the threaded limit nut 14 located at the bottom of the movable block 13 is rotated until it fits tightly against the bottom of the movable block 13, thereby limiting the movable block 13 and preventing the adjusted movable block 13 from sliding outside the first lead screw 12, ensuring that the adjustable guide structure is at a suitable height position.

[0039] When faced with color-coated plates of different widths, the operator rotates the rotating block 18 at one end of the second lead screw 16, causing the second lead screw 16 to rotate between the two mounting seats 15, which in turn drives the moving seat 17 to slide and guide on the surface of the lifting frame 2 through the guide groove. The moving seat 17 then drives the concave block 3 to move, ultimately achieving the adjustment of the distance between the two concave blocks 3 according to the width of the color-coated plate, thereby improving the application range of the device.

[0040] For color-coated sheets of different thicknesses, when both ends of the color-coated sheet are located inside the corresponding concave block 3, the operator rotates the adjusting screw 10. Under the guidance of the two guide rods 11, the adjusting plate 7 moves up and down, thereby adjusting the distance between the concave block 3 and the adjusting plate 7. This allows several top guide rollers 9 to fit against the upper surface of the color-coated sheet, adapting to color-coated sheets of different thicknesses and ensuring that the color-coated sheet is stably guided in the device.

[0041] During the coating process of the color-coated sheet, both ends of the color-coated sheet are located inside the corresponding concave blocks 3 and are attached to the outer walls of several side guide rollers 4. The bottom surface of the color-coated sheet is attached to the surface of several bottom guide rollers 6, and the top guide rollers 9 are attached to the upper surface of the color-coated sheet, forming a surrounding guide structure for the color-coated sheet. When the color-coated sheet moves during coating, several side guide rollers 4 rotate inside the concave blocks 3, several bottom guide rollers 6 rotate inside the corresponding rectangular grooves 5, and several top guide rollers 9 rotate between the corresponding two support blocks 8. The rotation of each guide roller provides guiding force to the color-coated sheet, ensuring that the color-coated sheet moves along the correct path during the coating process, thereby achieving the purpose of correction, improving coating quality and the application range of the device.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
