[0002] Cold-rolled steel strip, as an important metal material, has been widely used in the manufacturing industry due to its high strength, good ductility and precise dimensional control. The cold rolling process further processes the hot-rolled steel strip at room temperature to improve its mechanical properties and surface quality. Cold-rolled steel strip not only has excellent physical properties, but also has excellent surface finish and dimensional accuracy, which makes it play an irreplaceable role in many fields such as automobile manufacturing, machinery manufacturing, construction and home appliances. However, in the production and processing of cold-rolled steel strip, especially in the winding process, due to the differences in the shape, size and surface quality of the steel strip itself, as well as the limitations of the winding equipment and methods, some technical difficulties are often encountered.

[0003] In actual production, hot-rolled steel strips have various shapes, including normal and various abnormal shapes. Abnormal shapes such as wedge-shaped and double-peaked shapes pose great challenges to cold rolling and coiling due to their irregular shapes. When these special-shaped steel strips are cold-rolled and coiled, scratches are easily generated due to the contact between the steel strips or between the steel strips and the coiling equipment, especially when there are slight height differences or protrusions on the surface of the steel strips.

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0033] Embodiment: A cold rolling and winding device for steel strip with backing paper, such as Figure 1-Figure 10As shown, it includes a winding base 1, a winding machine 11 and a winding core shaft 12. The winding base 1 is installed with the winding machine 11, and the winding machine 11 is connected to the winding core shaft 12. The winding machine 11 can drive the winding core shaft 12 to rotate. It also includes a winding core plate 13, a steel clamping mechanism 2, a paper feeding mechanism 3 and a paper lifting mechanism 4. A plurality of winding core plates 13 are arranged around the outer ring of the winding core shaft 12. The distance between the winding core plate 13 and the winding core shaft 12 can be changed, that is, the distance between the winding core plate 13 and the winding core shaft 12 is adjusted to change the diameter of the hollow circle in the middle of the steel coil. The winding core plate 13 is provided with a steel clamping mechanism 2, a paper feeding mechanism 3 and a paper lifting mechanism 4. A steel clamping mechanism 2 for holding the steel belt mainly clamps the steel belt through the clamping plate 23 and the winding core plate 13, and the opening and closing of the clamping plate 23 is controlled by the ratchet assembly 22. A paper feeding mechanism 3 for conveying lining paper is provided on the winding base 1. A lining paper roll 32 is placed on the paper feeding mechanism 3. The lining paper passes over the roller 36 and the pressure roller 373 to ensure the tension of the lining paper. A paper lifting mechanism 4 for lifting and stabilizing the lining paper is provided on the paper feeding mechanism 3. The paper lifting mechanism 4 mainly fixes the lining paper through the sawtooth frame 43 to reduce the steps of manual control of the lining paper.

[0034] The staff adjusts the position of the core plate 13 according to the hollow inner diameter required for winding the steel coil (this is a conventional mechanism in the existing steel strip winding technology and is not described in detail here), and then starts the winding machine 11, which controls the winding core shaft 12 to rotate clockwise. After an opening plate gear 25 passes through the ratchet assembly 22, the winding machine 11 is closed. At this time, a clamping plate 23 is opened, and then the liner roll 32 is placed on the unwinding shaft 31, and the liner is pulled out. After passing the roller 36 of the paper feeding mechanism 3, it passes through the paper lifting machine. The sawtooth frame 43 of the structure 4 is fixed, and after the steel strip is inserted into the core plate 13, the lining paper is close to the steel strip. At this time, the staff starts the winder 11, and the winder 11 drives the core shaft 12 to rotate counterclockwise to perform the winding work. After the winding is completed, the lining paper is cut off, and the steel coil is removed from the core plate 13. When removing the steel coil, the distance between the core plate 13 and the core shaft 12 can be reduced, thereby reducing the contact area between the steel coil and the core plate 13, and the steel strip clamped in the core plate 13 can be pulled out, which is convenient for removing the steel coil.

[0035] like Figure 2-Figure 5As shown, the steel clamping mechanism 2 includes a rotating shaft 21, a ratchet assembly 22, a clamping plate 23, clamping teeth 24, a plate opening gear 25, a first torsion spring 26 and a support plate 27. The rotating shaft 21 is rotatably connected inside the winding core plate 13, and the clamping plate 23 is connected to the rotating shaft 21. A plurality of clamping teeth 24 are arranged on the inner side of the clamping plate 23. The clamping teeth 24 are made of rubber material and will not damage the steel belt. A first torsion spring 26 is sleeved on the rotating shaft 21. One end of the first torsion spring 26 is connected to the winding core plate 13, and the other end is connected to the clamping plate 23. The torsion force of the spring 26 makes the clamping plate 23 close to the core plate 13. The winder 11 is provided with a ratchet assembly 22. The end of the rotating shaft 21 close to the winder 11 passes through the core plate 13 and is connected to an opening gear 25. The ratchet assembly 22 is meshed with the opening gear 25, and the ratchet assembly 22 can only rotate in one direction, thereby assisting the clamping plate 23 to automatically open and close through the opening gear 25. The ends of the two support plates 27 are rotatably connected, one of which is rotatably connected to the clamping plate 23, and the other is rotatably connected to the core plate 13.

[0036] like Figure 3 and Figure 5 As shown, the ratchet assembly 22 includes a mounting rod 221, a ratchet 222, a pinion 223, a large gear 224, a ratchet plate 225 and a limiting plate 226. One end of the mounting rod 221 is connected to the winder 11, the ratchet 222 is fixedly connected to the mounting rod 221, the pinion 223 is rotatably connected to the mounting rod 221, the front side of the pinion 223 is fixedly connected to the limiting plate 226, the front side of the pinion 223 is rotatably connected to the ratchet plate 225, a torsion spring is arranged between the ratchet plate 225 and the pinion 223, the ratchet plate 225 is limitedly matched with the ratchet 222, the ratchet plate 225 is limitedly matched with the limiting plate 226, the rear side of the pinion 223 is connected to the large gear 224, the large gear 224 is rotatably connected to the mounting rod 221, and the outer ring of the large gear 224 can engage with the open plate gear 25.

[0037] The ratchet assembly 22 cooperates with the ratchet wheel 222, the ratchet plate 225 and the limit plate 226, as well as the meshing relationship between the small gear 223 and the large gear 224, so that the large gear 224 can only rotate clockwise, and then when the winding core shaft 12 and the winding core plate 13 rotate clockwise, the plate opening gear 25 is driven to rotate clockwise around the winding core shaft 12. When the plate opening gear 25 is meshed with the large gear 224, since the large gear 224 cannot rotate counterclockwise, the plate opening gear 25 rotates counterclockwise around the rotating shaft 21, thereby driving the rotating shaft 21 and the clamping plate 23 to rotate, so that the clamping plate 23 is in an open state, the angle between the clamping plate 23 and the winding core plate 13 becomes larger, the first torsion spring 26 is twisted, and after the two support plates 27 rotate with the clamping plate 23, the angle between the two support plates 27 is 180 degrees, two support plates 27 support the clamping plate 23, after the opening plate gear 25 is disengaged from the large gear 224, the clamping plate 23 still remains in an open state, and after the steel strip is inserted between the clamping plate 23 and the winding core plate 13, the steel strip squeezes the support plate 27, thereby contacting the support plate 27 for the supporting effect of the clamping plate 23, and the opening plate gear 25 and the rotating shaft 21 rotate clockwise under the torsional force of the first torsion spring 26, and the clamping plate 23 clamps the steel strip, and the clamping teeth 24 are made of rubber material, which increases the friction between the clamping teeth 24 plate and the steel strip, and the winder 11 drives the winding core shaft 12 to rotate counterclockwise. At this time, the opening plate gear 25 is meshed with the large gear 224, and the large gear 224 can rotate counterclockwise without applying resistance to the opening plate gear 25, and as the winding core shaft 12 rotates, the steel strip is wound.

[0038] like Figure 6-Figure 8 As shown, the paper feeding mechanism 3 includes an unwinding shaft 31, a liner roll 32, a mounting plate 33, a stabilizing shaft 34, a second torsion spring 35, a roller 36 and a pressing assembly 37. The reel 11 is connected to the unwinding shaft 31, the unwinding shaft 31 is located below the winding core shaft 12, and the liner roll 32 is sleeved on the unwinding shaft 31. The unwinding shaft 31 can support the liner roll 32 to rotate freely, or drive the liner roll 32 to rotate through a certain driving mechanism. The reel base 1 is connected to the stabilizing shaft 34, and both ends of the stabilizing shaft 34 are The mounting plate 33 is rotatably connected, and the two ends of the stabilizing shaft 34 are sleeved with second torsion springs 35, one end of the second torsion spring 35 is connected to the stabilizing shaft 34, and the other end is connected to the mounting plate 33. The second torsion spring 35 is used to maintain the vertical state of the mounting plate 33. A roller 36 is slidably connected between the two mounting plates 33. The roller 36 is composed of a middle shaft and an outer ring sleeve, and the sleeve can rotate on the shaft. A guide rod is set on the rear mounting plate 33, and the shaft of the roller 36 is slidably connected to the guide rod. Figure 8 A pressing assembly 37 for pressing the backing paper is arranged on the winding base 1.

[0039] like Figure 7 and Fig. 9As shown, the clamping assembly 37 includes a connecting plate 371, a connecting plate 372 and a clamping roller 373. The connecting plate 371 is fixedly connected to the winding base 1. A clamping roller 373 in contact with the lining paper is slidably connected up and down inside the connecting plate 371. The outer ring of the clamping roller 373 is made of flexible material and will not damage the lining paper when squeezing the lining paper. The lower end of the connecting plate 372 is rotatably connected to the middle of the mounting plate 33, and the upper end of the connecting plate 372 is rotatably connected to the end of the clamping roller 373.

[0040] After the lining paper is pulled out, it passes over the roller 36 between the mounting plates 33 and is then placed in the clamping plate 23. After the steel strip is inserted into the clamping plate 23, the lining paper is clamped together, so that the lining paper is rolled up together with the steel strip. When the lining paper passes through the pressing roller 373, it can be smoothed to ensure that the lining paper and the steel strip fit together. As the diameter of the steel coil increases, the pressing roller 373 is pushed to slide downward in the connecting plate 371, and the pressing roller 373 slides downward in the connecting plate 371, and at the same time pushes the upper end of the connecting plate 372 to move downward, so that the connecting plate 37 When the lower end of the mounting plate 33 rotates on the mounting plate 33, the mounting plate 33 is pushed to rotate around the stabilizing shaft 34, the second torsion spring 35 is twisted, and the position of the over roller 36 relative to the steel coil changes with the rotation of the mounting plate 33. When the steel coil is taken out, the squeezing force on the pressing roller 373 disappears, the second torsion spring 35 rebounds, the mounting plate 33 and the over roller 36 rotate to reset, and the pressing roller 373 is pushed to slide and reset in the connecting plate 371 through the connection relationship between the connecting plate 372 and the pressing roller 373 and the rebound force of the second torsion spring 35.

[0041] like Figure 7 and Figure 8 As shown, the paper lifting mechanism 4 includes a first servo motor 41, a first screw rod 42, a sawtooth frame 43, a ring gear 44 and a rack 45. The front mounting plate 33 is rotatably connected to the first screw rod 42 in the up and down directions. The first servo motor 41 is installed on the top of the front mounting plate 33. The output shaft of the first servo motor 41 is fixedly connected to the top of the first screw rod 42. The first screw rod 42 is threadedly connected to the front end of the shaft of the roller 36, so that the roller 36 can slide up and down with the rotation of the screw rod, and cooperate with the guide rod on the rear mounting plate 33 to ensure the stable movement of the roller 36 between the mounting plates 33. The rear mounting plate 33 is connected to the rack 45, the sawtooth frame 43 is rotatably connected to the two ends of the shaft of the roller 36, and the sawtooth frame 43 is provided with tooth nails that can penetrate the lining paper. The rear side of the sawtooth frame 43 is provided with a ring gear 44, the ring gear 44 is sleeved on the roller 36, and the ring gear 44 is meshed with the rack 45.

[0042] After the liner is pulled out, it is pressed on the sawtooth frame 43 and exceeds a part of the sawtooth frame 43. Then, the first servo motor 41 is turned on. The first servo motor 41 drives the first screw rod 42 to rotate, and the roller 36 slides upward in the mounting plate 33. At the same time, the ring gear 44 at the rear end of the sawtooth frame 43 is engaged with the rack 45, so that the ring gear 44 drives the sawtooth frame 43 to rotate clockwise, and the liner is driven to approach the clamping plate 23 through the sawtooth frame 43. Then, after the steel belt is inserted, the steel belt drives the liner to be inserted into the core plate 13 together. , then the first servo motor 41 is controlled to reverse, and the roller 36 and the sawtooth frame 43 are lowered through the first screw rod 42. During the descending process, the sawtooth frame 43 engages with the rack 45 through the gear ring 44, and the sawtooth frame 43 rotates counterclockwise. Finally, the sawtooth frame 43 is lower than the roller 36, which will not affect the winding of the lining paper and the steel strip. During the increase of the steel coil, the first servo motor 41 and the first screw rod 42 rotate with the mounting plate 33, and the roller 36 that has been lowered will not affect the winding of the steel strip and the lining paper.

[0043] like Fig. 9 and Fig.10 As shown, it also includes a cutting mechanism 5, which includes a second servo motor 51, a second screw rod 52, a connecting piece 53 and a cutting ring 54. The second servo motor 51 is installed on the clamping roller 373, and the second screw rod 52 is rotatably connected inside the clamping roller 373. The cutting ring 54 is slidably connected to the clamping roller 373. A connecting piece 53 is arranged on the inner side of the cutting ring 54. The connecting piece 53 is threadedly connected to the second screw rod 52, and the second screw rod 52 is connected to the output shaft of the second servo motor 51.

[0044] The lining paper needs to match the width of the steel belt. According to the width of the steel belt, the second servo motor 51 is turned on, and the position of the cutting ring 54 on the clamping roller 373 is adjusted through the threaded connection between the second screw rod 52 and the connecting piece 53. When the clamping roller 373 contacts the lining paper, the excess lining paper can be cut to ensure the overall width of the steel coil. After adjustment, the second servo motor 51 is turned off.

[0045] First, the staff adjusts the distance between the core plate 13 and the core shaft 12 according to the required hollow inner diameter of the steel coil. Then, the winder 11 is started, which controls the core shaft 12 to rotate clockwise. Through the action of the ratchet assembly 22, a clamping plate 23 is opened to insert the steel strip. At this time, the liner is pulled out from the unwinding shaft 31, guided by the paper feeding mechanism 3, especially the roller 36, and fixed by the sawtooth frame 43 of the paper lifting mechanism 4. After the steel strip is inserted between the opened clamping plate 23 and the core plate 13, the winder 11 is started again to drive the core shaft 12 to rotate counterclockwise for winding. During the winding process, the clamping plate 23 of the steel clamping mechanism 2 clamps the steel strip in time and keeps it stable with the cooperation of the ratchet assembly 22 and the first torsion spring 26. At the same time, the liner is clamped by the steel strip and rolled together, and the pressing roller 373 in the pressing assembly 37 ensures that the liner fits the steel strip flatly. As the diameter of the steel coil increases, the clamping roller 373 descends, pushing the mounting plate 33 to rotate around the stabilizing shaft 34, releasing more lining paper to accommodate the growth of the steel coil. The sawtooth frame 43 of the paper lifting mechanism 4 lifts the lining paper at the beginning of winding, and descends in time during the winding process to avoid interference. In addition, the cutting mechanism 5 adjusts the position of the cutting ring 54 according to the width of the steel strip to ensure that the width of the lining paper matches the steel strip and the excess part is cut off.

[0046] The cold rolling and coiling method of steel strip with lining paper includes the following specific steps:

[0047] S1. The staff inserts one end of the steel belt into the winding core plate 13, pulls out one end of the liner roll 32 on the unwinding shaft 31, and fixes it on the sawtooth frame 43;

[0048] S2, start the winder 11 and the first servo motor 41, the first servo motor 41 lifts the sawtooth frame 43 through the first screw rod 42, the liner is close to the steel strip, when the winder 11 rotates, the clamping plate 23 clamps the steel strip and reels the steel strip, and the pressure roller 373 presses the liner;

[0049] S3, start the first servo motor 41 again, the output shaft rotates in the opposite direction, the sawtooth frame 43 moves downward through the first screw rod 42, and rotates in cooperation with the gear ring 44 and the rack 45;

[0050] S4. As the diameter of the steel coil increases, the pressure roller 373 descends, the mounting plate 33 rotates around the stabilizing shaft 34, and the liner roll 32 continuously unwinds the liner. After the winding is completed, the winder 11 is closed and the steel coil is removed.
