[0014] Technical effects and advantages of the present invention:

[0015] 1. By setting up the dust sticking structure, the rotary motor drives the first bidirectional screw to rotate, so that the two adjustment blocks are close to each other, and the two rollers and the dust sticking stickers thereon are closely attached to the upper and lower surfaces of the metal strip through the sliding guide of the slider on the first slide rod. The dust sticking sticker is made of silicone rubber, which can effectively absorb the dust on the surface of the strip to prevent the dust from affecting the subsequent laminating operation. At the same time, the dust sticking sticker is detachably connected to the roller through Velcro, which is convenient for operators to replace and clean, ensuring the continuity and stability of the dust sticking effect, improving the cleanliness of the metal strip before laminating, thereby improving the laminating quality and overall processing efficiency;

[0016] 2. By setting up a hot pressing and cutting structure, the second bidirectional screw drives the two first L-shaped seats to approach each other, so that the two hot pressing rollers are closely attached to the metal strip and the film materials on the front and back sides thereof under the sliding guidance of the second L-shaped seat and the second slide rod. The rotation of the hot pressing rollers can evenly and tightly laminate the film materials on the front and back sides of the strip, thereby achieving high-quality laminating operation. At the same time, the third bidirectional screw drives the two cutting knives to approach each other, and the laminated strip is accurately cut to ensure that the cutting length meets the requirements, which not only improves the accuracy of laminating and cutting, but also simplifies the operation process, and improves the overall processing efficiency and product quality.

[0017] 3. By setting up the straightening measurement structure, the electric push rod drives the second clamping plate and the first clamping plate to tightly clamp one end of the metal strip and the film material to achieve the straightening operation of the rolled strip. At the same time, the stepper motor drives the screw to rotate, so that the threaded block drives the movable frame to move, and then drives the clamped strip to move between the two cutting knives. During the movement of the movable frame, the indicator slides on the surface of the measuring ruler to accurately read the moving distance of the strip, that is, the cutting length of the strip after lamination. This not only realizes the precise straightening and measurement of the strip, but also improves the accuracy and efficiency of cutting, providing reliable guarantee for subsequent processing operations.

Fixedly connected, two adjusting blocks 10 and two sliding blocks 11 are respectively arranged on the outside of the first bidirectional screw rod 7 and the first sliding rod 8, the adjusting block 10 is threadedly connected to the outside of the first bidirectional screw rod 7, the sliding block 11 is slidably connected to the first sliding rod 8, a roller 12 is rotatably arranged between the sliding block 11 and the adjusting block 10, a sticky sticker 13 is wound on the roller 12, and Velcro 14 is pasted on the outer surface of the roller 12 and the back of the sticky sticker 13, the sticky sticker 13 is detachably connected to the roller 12 through the Velcro 14, and the sticky sticker 13 is made of silicone rubber.

[0031] Specifically, the structure is used to absorb dust on the upper and lower surfaces of the metal strip to avoid affecting the subsequent coating operation. The specific application method is that after one end of the metal strip is fed from the feed roller 3, it is between the sticky stickers 13 belonging to the two rollers 12. At this time, the rotating motor 9 drives the first bidirectional screw 7 inside one of the mounting frames 6 to rotate, so that the two adjustment blocks 10 threadedly installed on the outside of the first bidirectional screw 7 are close to each other, and the two sliders 11 are guided by sliding on the outside of the first slide bar 8, so that the two rollers 12 are close to each other, so that the strip is clamped between the two rollers 12, and the two rollers 12 are rotated between the corresponding sliders 11 and the adjustment blocks 10, so that the sticky stickers 13 on the outside of the rollers 12 are attached to the surface of the strip to perform dust absorption operation, so that the dust attached to the front and back sides of the strip can be removed;

[0032] The operator can separate the sticky sticker 13 from the rotating roller 12 through the Velcro 14, so that the sticky sticker 13 can be easily replaced and cleaned.

[0033] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown in , 3 and 8, a hot pressing and cutting structure is arranged on one side of the dust-sticking structure, and the hot pressing and cutting structure includes two guide rails 15, and the two guide rails 15 are fixed on the top of the processing table 1 and are located on one side of the mounting frame 6. Two support blocks 16 are fixedly installed on the outer walls of the two guide rails 15, wherein a second bidirectional screw rod 17 is arranged between the two support blocks 16, and a second slide rod 18 is arranged between the other two support blocks 16. The external thread of the second bidirectional screw rod 17 is installed with two symmetrically distributed first L-shaped seats 19, and the external sliding portion of the second slide rod 18 is installed with two symmetrically distributed second L-shaped seats 20, and a hot pressing roller 21 is rotatably arranged between the first L-shaped seat 19 and the second L-shaped seat 20.

[0034] Specifically, this structure is used to perform hot pressing lamination on the strip and the film material on the front and back sides of the strip. The specific application method is that when the strip and the film material on the front and back sides of the strip are between the two hot pressing rollers 21, the operator rotates the second bidirectional screw 17 to make the two first L-shaped seats 19 approach each other, and drives the two hot pressing rollers 21 to approach each other under the sliding guidance of the second L-shaped seat 20 and the second slide bar 18. After the strip and the film material on the front and back sides of the strip are clamped and pressed by the two hot pressing rollers 21 brackets, the two hot pressing rollers 21 are rotated by the movement of the strip, and the two rotating hot pressing rollers 21 can compound the film material on the front and back sides of the strip to achieve the purpose of lamination.

[0035] In a specific embodiment, as shown in the attached Figure 1 , 2As shown in , 3, and 8, the hot pressing and cutting structure also includes a third bidirectional screw rod 22, which is installed inside one of the guide rails 15, and a third slide rod 23 is arranged inside the other guide rail 15, a servo motor 24 is arranged at the top of the third bidirectional screw rod 22, two mounting bars 25 are arranged between the two guide rails 15, and cutting knives 26 are arranged on the surfaces of the two mounting bars 25, the servo motor 24 is fixedly installed on the top of one of the guide rails 15, and the output end of the servo motor 24 is fixedly connected to the third bidirectional screw rod 22 inside one of the guide rails 15, the two ends of the two mounting bars 25 are connected to the third bidirectional screw rod 22 and the third slide rod 23 by threaded connection and sliding connection respectively, and the two cutting knives 26 are symmetrically installed on the surfaces of the corresponding mounting bars 25 by screws.

[0036] Specifically, this structure is used to cut the laminated strip. In specific applications, when the strip passes through two hot pressing rollers 21 to laminate the film on the front and back sides of the strip, the strip is simultaneously between two symmetrically distributed cutting knives 26. At this time, the servo motor 24 drives the third bidirectional screw 22 to operate, driving the two mounting bars 25 to approach each other under the action of the third slide bar 23. The two mounting bars 25 drive the two symmetrically distributed cutting knives 26 to approach each other to cut the laminated strip.

[0037] In a specific embodiment, as shown in the attached Figure 1 , 6 As shown in Figure 8, a straightening measurement structure is provided on one side of the hot pressing and cutting structure, and the straightening measurement structure includes a movable frame 27. The movable frame 27 is located on the outer wall of the processing table 1 and on one side of the two guide rails 15. A first clamping plate 28 is fixedly installed inside the movable frame 27, and a second clamping plate 29 is provided on the top of the first clamping plate 28. Two electric push rods 30 are provided on the top of the movable frame 27, and the output ends of the two electric push rods 30 are connected to the second clamping plate 29, and the second clamping plate 29 is slidably connected inside the movable frame 27.

[0038] Specifically, this structure is used to clamp one end of the strip and film material between the first clamping plate 28 and the second clamping plate 29, so as to facilitate the straightening of the rolled metal strip. In specific application, after one end of the strip and film material is between the first clamping plate 28 and the second clamping plate 29, the two electric push rods 30 on the top of the movable frame 27 drive the second clamping plate 29 to extend downward, thereby clamping one end of the strip and film material between the first clamping plate 28 and the second clamping plate 29.

[0039] In a specific embodiment, as shown in the attached Figure 1 , 6As shown in Figures 7 and 8, the straightening measurement structure also includes a screw 31. The two outer walls of the processing table 1 are provided with mounting grooves 32. The screw 31 is installed in one of the mounting grooves 32, and a guide rod 33 is provided in the other mounting groove 32. A stepper motor 34 is provided at one end of the screw 31. A threaded block 35 and a guide block 36 are provided on the outside of the screw 31 and the guide rod 33, respectively. The stepper motor 34 is fixedly installed at one end of the processing table 1, and the output end of the stepper motor 34 is fixedly connected to the screw 31. The threaded block 35 is threadedly connected to the outside of the screw rod, and the guide block 36 is slidably connected to the guide rod 33. The threaded block 35 and the slider 11 are both fixedly installed on the inner wall of the movable frame 27. A measuring ruler 37 is fixedly provided at the bottom of the processing table 1. An indicator mark 38 is slidably provided on the surface of the measuring ruler 37, and the top of the indicator mark 38 is fixedly installed at the bottom of the movable frame 27.

[0040] Specifically, in this structure, after one end of the strip and the film material is clamped between the first clamping plate 28 and the second clamping plate 29, the stepping motor 34 drives the screw 31 to rotate, so that the threaded block 35 drives the movable frame 27 to move, and the guide block 36 slides and guides outside the guide rod 33, and the movable frame 27 drives the displacement of the clamped strip between the two cutting knives 26 to change, and the displacement change determines the length of the strip cut after lamination;

[0041] In order to accurately read the cutting length of the strip, the movable frame 27 will drive the indicator mark 38 to move in contact with the surface of the measuring ruler 37 during the movement, and the distance between the movable frame 27 and the cutting knife 26 is read by the sliding distance of the indicator mark 38 on the surface of the measuring ruler 37. The distance between the movable frame 27 and the cutting knife 26 determines the cutting length of the strip after the film is finally laminated, so that the laminated strip can be accurately cut and used, thereby improving the processing efficiency.

[0042] Specifically, the distance between the movable frame 27 and the cutting knife 26 = the distance between the strip and the cutting knife 26 = the final cutting length of the strip.

[0043] Working principle of the present invention:

[0044] The present invention provides an automatic film coating device for the surface of a rolled metal strip. In specific operation, the strip on the feeding roller 3 first passes through the sticky stickers 13 on the surfaces of two rotating rollers 12, and the dust on the front and back surfaces of the strip is adsorbed and removed by the sticky structure to prevent the dust from affecting the coating effect. The sticky stickers 13 can be disassembled and replaced by the Velcro 14 and the rotating rollers 12.

[0045] After the dust is removed, the strip is stretched and passed between the two cutting knives 26 and the two hot pressing rollers 21 of the hot pressing cutting structure, and is clamped and fixed by the first clamping plate 28 and the second clamping plate 29 of the straightening and measuring structure, so that the rolled strip is moved and straightened. At the same time, the film on the two laminating rollers 5 is passed around the sticky sticker 13 on the surface of the rotating roller 12, and passed between the two cutting knives 26 and the two hot pressing rollers 21, and is also clamped and fixed by the first clamping plate 28 and the second clamping plate 29. The two hot pressing rollers 21 are used to squeeze each other to laminate the film on the top and bottom of the strip on the front and back sides of the strip.

[0046] After the strip and one end of the film are clamped at the first clamping plate 28 and the second clamping plate 29, the strip is stretched and moved by moving the movable frame 27, and the length of the strip is read according to the data on the measuring ruler 37. Finally, the strip is cut to a suitable length by two cutting knives 26 to complete the final process. The final state is as shown in the attached figure. Figure 8 shown.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
