[0026] In some optional specific embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the tension adjustment mechanism includes an adjusting roller 11 arranged between two adjacent rolling assemblies, and two control boxes 2 are respectively provided with a plurality of second avoidance holes 55 matched with the adjusting roller 11, and the two ends of the adjusting roller 11 respectively penetrate the corresponding second avoidance holes 55, and the two ends of the adjusting roller 11 are respectively rotatably connected with a swing plate 54, and the swing plate 54 is rotatably connected with a fixing frame 56, and the fixing frame 56 is fixedly connected to the control box 2, and the side of the swing plate 54 away from the adjusting roller 11 is fixedly connected with a second damping plate 57, and the side of the second damping plate 57 away from the swing plate 54 is provided with a third damping plate 58, and the third damping plate 5 8 is in contact with the second damping disc 57, a third connecting shaft 59 is fixedly connected to the side of the third damping disc 58 away from the second damping disc 57, the third connecting shaft 59 is rotatably connected to the fixing frame 56, one end of the third connecting shaft 59 away from the third damping disc 58 is fixedly connected to the third bevel gear 60, a plurality of fourth bevel gears 61 are fixedly sleeved on the outside of the rotating shaft 8, and the third bevel gears 60 are meshed with the corresponding fourth bevel gears 61, a third hydraulic telescopic rod 62 is fixedly installed on the fixing frame 56, and a friction plate 63 is fixedly connected to the output end of the third hydraulic telescopic rod 62, and the friction plate 63 is in contact with the second damping disc 57; When the tension of the plate needs to be adjusted, the friction plate 63 is driven downward by the third hydraulic telescopic rod 62 so that the friction plate 63 is no longer in contact with the second damping plate 57, and the position restriction of the second damping plate 57 is released. When the rotating shaft 8 rotates, the rotating shaft 8 drives the fourth bevel gear 61 to rotate, and the fourth bevel gear 61 drives the third connecting shaft 59 and the third damping plate 58 to rotate through the third bevel gear 60. The third damping plate 58 drives the second damping plate 57 and the swing plate 54 to rotate through the friction force, and the swing plate 54 can drive the adjusting roller 11 to contact the bottom of the plate. When the force of the adjusting roller 11 pressing the plate reaches a preset value, as the third damping plate 58 continues to rotate The third damping disk 58 cannot drive the second damping disk 57 and the swing plate 54 to rotate. When the tension of the plate is greater than the preset value, the plate presses the adjusting roller 11 to make the adjusting roller 11 and the swing plate 54 rotate downward, and the second damping disk 57 slides in the opposite direction relative to the third damping disk 58. When the tension of the plate is less than the preset value, the pressure on the adjusting roller 11 becomes smaller, and the third damping disk 58 drives the second damping disk 57 and the swing plate 54 to rotate again through friction force, so that the adjusting roller 11 moves the plate upward. When the pressure applied by the adjusting roller 11 to the plate reaches the preset value, the third damping disk 58 rotates again relative to the second damping disk 57, so as to adjust the tension of the plate.

[0027] This embodiment also provides a metal sheet rolling process, including the metal sheet rolling device as described above, comprising the following steps: Step 1: The movable shaft 6 is driven to move horizontally through the horizontal position positioning structure, and the movable shaft 6 drives two adjacent first connecting shafts 5 to move vertically in different directions through the connecting plate 7, so as to change the spacing between the two rolling rollers 3 on each group of rolling assemblies; Step 2: When the spacing between the two rolling rollers 3 on each rolling assembly is adjusted, the rotating shaft 8 is driven to rotate by the driving member; Step 3: The rotating shaft 8 drives two adjacent first connecting shafts 5 to rotate synchronously in different directions through the synchronous rotation structure, so that the two rolling rollers 3 on each group of rolling assemblies rotate synchronously in different directions; Step 4: The plate is guided and supported by a plurality of support rollers 10 , and the plate is rolled by the self-rotating rolling roller 3 .

[0028] Working principle: according to the needs of the plate to be rolled, the staff drives the movable shaft 6 to move horizontally through the horizontal position positioning structure, and the movable shaft 6 drives the two adjacent first connecting shafts 5 to move in different directions in the vertical direction through the connecting plate 7, so as to change the spacing between the two rolling rollers 3 on each group of rolling components. When the spacing between the two rolling rollers 3 on each group of rolling components is adjusted, the rotating shaft 8 is driven to rotate by the driving member, and the rotating shaft 8 drives the two adjacent first connecting shafts 5 to rotate synchronously in different directions through the synchronous rotation structure, so that the two rolling rollers 3 on each group of rolling components rotate synchronously in different directions. The plate is guided and supported by a number of supporting rollers 10, and the plate is rolled by the self-rotating rolling rollers 3, so as to facilitate the adjustment of the spacing between the two rolling rollers 3 on each group of rolling components, thereby improving the adjustment efficiency, reducing the downtime, and facilitating the popularization and use; The first hydraulic telescopic rod 14 drives the fixed plate 12 and the movable shaft 6 in the horizontal direction, and the movable shaft 6 drives the corresponding two first connecting shafts 5 to change the spacing between them through the connecting plate 7. The synchronous rotating structure guides the vertical sliding of the lifting seat 4 and the first connecting shaft 5, so that the first connecting shaft 5 and the lifting seat 4 slide vertically relative to the control box 2. When each movable shaft 6 is adjusted to a preset position, the rotating shaft 8 is driven to rotate by the driving member, and the rotating shaft 8 drives the first support sleeve 24 and the second damping ring 22 to rotate through the guide bar 26. The initial state of the tension spring 30 is in the tension state. In the state, a tension force is applied to the movable frame 23 by stretching the spring 30, so that the second damping ring 22 is tightly attached to the first damping ring 19. When the second damping ring 22 rotates, the second damping ring 22 drives the first damping ring 19 and the threaded sleeve 18 to rotate by friction. The threaded sleeve 18 drives the threaded column 20, the support seat 16 and the first guide column 21 to slide relative to the second mounting seat 17, so that the support seat 16 moves toward the fixed seat 15. When the support seat 16 contacts the fixed seat 15, as the rotating shaft 8 continues to rotate, the second damping ring 22 cannot drive the first damping ring 19 and the threaded sleeve 18 by friction. 8 continues to rotate, and the support seat 16 stops after moving to the preset position. The fixed seat 15 and the fixed plate 12 are supported by the support seat 16 to reduce the possibility of horizontal shaking of the fixed plate 12 and the movable shaft 6. When the position of the support seat 16 is adjusted, the movable plate 32 and the support plate 33 are driven to move upward by the second hydraulic telescopic rod 34. The top of the support plate 33 slides on the inclined surface of the support block 31. The support plate 33 pushes the support block 31, the connecting frame 28, the movable frame 23 and the first support sleeve 24 to move horizontally. The first support sleeve 24 drives the guide bar 26 to slide in the guide groove 25. The first support sleeve 24 drives the second damping ring 22 to no longer contact the first damping ring 19, and the movable frame 23 drives the third damping ring 27 to press on the side of the first damping ring 19 away from the second damping ring 22 through the connecting frame 28. The position of the first damping ring 19 is limited by the third damping ring 27 to prevent the first damping ring 19 and the threaded sleeve 18 from rotating and shaking relative to the third damping ring 27 and the control box 2 due to non-human factors, and the second damping ring 22 is no longer in contact with the first damping ring 19. When the rotating shaft 8 rotates, the second damping ring 22 is prevented from continuously rotating relative to the first damping ring 19 due to friction. The movable shaft 6 drives the distance between the corresponding two first connecting shafts 5 to change through the connecting plate 7, and the first connecting shaft 5 drives the lifting seat 4 and the second supporting sleeve 38 to slide vertically relative to the prism 35. The motor 49 drives the second worm 48 to rotate, and the second worm 48 drives the two second worm wheels 47 to rotate. The second worm wheel 47 can drive the rotating shaft 8 and the first worm 36 to rotate. The first worm 36 drives the prism 35, the second supporting sleeve 38 and the first bevel gear 39 to rotate through the first worm wheel 37. The first bevel gear 39 can drive the first connecting shaft 5 and the rolling roller 3 to rotate through the second bevel gear 40, so that the two rolling rollers 3 rotate synchronously in different directions, and the plate is rolled by the rolling roller 3. When the first connecting shaft 5 rotates, the first connecting shaft 5 drives the second gear ring 46 to rotate, and the second gear ring 46 drives the fourth damping ring 44 to rotate through the first gear ring 45. The fourth damping ring 44 drives the first damping disk 43 and the second connecting shaft 41 to rotate through friction, and the second connecting shaft 41 drives the scraper 42 to contact the rolling roller 3 When the scraper 42 contacts the rolling roller 3, as the first gear ring 45 and the fourth damping ring 44 continue to rotate, the fourth damping ring 44 cannot drive the first damping plate 43 and the second connecting shaft 41 to rotate again by friction, so that the scraper 42 always keeps in close contact with the rolling roller 3. As the rolling roller 3 rotates, the debris on the rolling roller 3 is scraped off by the scraper 42, and the debris on the upper rolling roller 3 in each rolling assembly falls into the second collecting box 51, and the debris on the lower rolling roller 3 in each rolling assembly falls into the second collecting box 51. The debris on a rolling roller 3 falls into the first collecting box 50. The staff drives the first collecting box 50 to slide relative to the base 1 so that the first collecting box 50 is no longer located under the rolling roller 3, which is convenient for cleaning the debris in the first collecting box 50. The second collecting box 51 moves up to separate the insert block 52 from the support plate 53, and the second collecting box 51 can be removed. The surface of the rolling roller 3 used for rolling will adhere to the debris of the plate during rolling, which is convenient for cleaning the debris adhered to the surface of each rolling roller 3 during rolling. When the tension of the plate needs to be adjusted, the friction plate 63 is driven downward by the third hydraulic telescopic rod 62 so that the friction plate 63 is no longer in contact with the second damping plate 57, and the position restriction of the second damping plate 57 is released. When the rotating shaft 8 rotates, the rotating shaft 8 drives the fourth bevel gear 61 to rotate, and the fourth bevel gear 61 drives the third connecting shaft 59 and the third damping plate 58 to rotate through the third bevel gear 60. The third damping plate 58 drives the second damping plate 57 and the swing plate 54 to rotate through the friction force, and the swing plate 54 can drive the adjusting roller 11 to contact the bottom of the plate. When the force of the adjusting roller 11 pressing the plate reaches a preset value, as the third damping plate 58 continues to rotate The third damping disk 58 cannot drive the second damping disk 57 and the swing plate 54 to rotate. When the tension of the plate is greater than the preset value, the plate presses the adjusting roller 11 to make the adjusting roller 11 and the swing plate 54 rotate downward, and the second damping disk 57 slides in the opposite direction relative to the third damping disk 58. When the tension of the plate is less than the preset value, the pressure on the adjusting roller 11 becomes smaller, and the third damping disk 58 drives the second damping disk 57 and the swing plate 54 to rotate again through friction force, so that the adjusting roller 11 moves the plate upward. When the pressure applied by the adjusting roller 11 to the plate reaches the preset value, the third damping disk 58 rotates again relative to the second damping disk 57, so as to adjust the tension of the plate.
