Description

Technical Field

[0001] This utility model relates to the technical field of steel strip processing equipment, specifically a winding device for the production of ultra-thin steel strips. Background Technology

[0002] In utility model patent application CN221939781U, published on November 1, 2024, entitled "A Fixing Structure for Cold-Rolled Ultra-Thin Steel Strip Production," this utility model discloses a fixing structure for cold-rolled ultra-thin steel strip production, belonging to the technical field of steel strip processing equipment. The key technical point is that the fixing structure for cold-rolled ultra-thin steel strip production includes a support mechanism, within which a rotating mechanism is arranged, and within which a fixing mechanism is arranged; the fixing mechanism includes a stabilizing ring and an inner screw cylinder, and the number of stabilizing rings... Four stabilizing rings are uniformly fixedly installed on the outside of the rotating mechanism. An extension rod extending into the rotating mechanism is inserted inside each stabilizing ring. A first fixing plate is fixedly installed at the end of the extension rod located outside the rotating mechanism. An inner screw is fixedly installed inside the rotating mechanism. An adjusting screw is installed on the internal thread of the inner screw. An adjusting cone is fixedly installed on the right side of the adjusting screw, and a handle is fixedly installed on the left side. The left side of the end of the extension rod located inside the rotating mechanism is inclined, and the outside of the adjusting cone contacts the inclined surface of the extension rod. The advantages are: This fixing structure for cold-rolled ultra-thin steel strip production, through the setting of the fixing mechanism, support mechanism, and rotating mechanism, allows for convenient fixing of the inner and outer rings of different types of cold-rolled ultra-thin steel strips during processing. Simultaneously, it can be used with equipment to realize winding and unwinding functions, ensuring the safety of the wound cold-rolled ultra-thin steel strips.

[0003] In the aforementioned patents or prior art, cold-rolled steel strip often experiences problems such as burrs or deviation during the winding process. This results in an imbalance between the left and right sides of the steel strip during winding, causing deformation and residual stress accumulation. This leads to stress release between the coil layers, ultimately causing the outer edge of the steel coil to loosen. The steel strip generates tremendous destructive force during this process, which can damage equipment and easily injure workers. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for the production of ultra-thin steel strips, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coiling device for producing ultra-thin steel strip, comprising a steel strip coiler, a lifting device, a stress detection device, and a burr grinding device; the lifting device is vertically arranged on one side of the steel strip coiler, and the lifting end of the lifting device can vertically move up and down according to the different radii of the steel coil wound on the coiling roller of the steel strip coiler; the stress detection device is horizontally arranged and fixedly connected to the lifting end of the lifting device, and the stress detection device is always located at the center above the coiling roller, and the stress detection device includes a vertical... The linearly moving arc plate and detection rod ensure that the bottom surface of the arc plate always contacts the outermost edge of the steel coil wound on the winding roller of the steel strip winding machine. The detection rod is vertically positioned on the top surface of the arc plate. When the steel coil undergoes slight deformation due to stress release, the outermost edge of the steel coil will cause the arc plate to move vertically upward, which in turn will cause the detection rod to move upward. Workers can then observe the detection rod to check whether the stress of the steel coil is within a safe range. The burr grinding device is located on both sides of the stress detection device and is used to grind the burrs on both sides of the steel strip before it is wound by the winding roller.

[0006] Furthermore, the lifting device includes: a vertical telescopic rod, a fixed rod, and a reinforcing rib. The vertical telescopic rod is vertically installed on one side of the steel strip winding machine. The top of the vertical telescopic rod can extend vertically upward as the amount of steel coil wound on the winding roller of the steel strip winding machine increases. The fixed rod is horizontally installed and fixedly connected to the top of the vertical telescopic rod. The fixed rod is fixedly connected to the stress detection device. The reinforcing rib is used to strengthen the connection between the fixed rod and the stress detection device.

[0007] Furthermore, the stress detection device includes: a connecting plate, an arc-shaped plate, and four lifting rods. The connecting plate is horizontally set and fixedly connected to the fixed rod. A horizontal arc-shaped plate is set below the connecting plate. The bottom surface of the arc-shaped plate is arc-shaped. Through holes are set at the four corners of the connecting plate. The bottom end of each lifting rod passes through the through holes at the four corners of the connecting plate and is fixedly connected to the top surface of the arc-shaped plate. The top end of the lifting rod is always located above the connecting plate.

[0008] Furthermore, the bottom surface of the curved plate is equipped with several pulleys. The pulleys are always in contact with the outermost edge of the steel coil wound by the winding roller on the steel strip winding machine. The rotation direction of the pulleys is the same as or opposite to the rotation direction of the winding roller on the steel strip winding machine.

[0009] Furthermore, each lifting rod is equipped with a vertical spring on its outer side, and each spring is located between the arc-shaped plate and the connecting plate.

[0010] Furthermore, the stress detection system also includes two synchronization plates, the bottom surface of which is fixedly connected to the top of the two lifting rods to achieve synchronous movement of the lifting rods.

[0011] Furthermore, a vertical detection rod is fixedly connected to the center of each synchronization plate. The bottom end of the detection rod is located on the top surface of the arc plate, and the other end of the detection rod passes through the connecting plate and extends out of the connecting plate. Two parallel grooves are provided on the surface of the detection rod, and the two grooves represent the maximum and minimum stress during the steel strip winding process, respectively.

[0012] Furthermore, the burr grinding device includes a horizontal telescopic rod, a rotating telescopic rod, and a grinding block. The horizontal telescopic rod is aligned with the axis of the winding roller on the steel strip winding machine. The top surface of the horizontal telescopic rod is fixedly connected to the bottom surface of the connecting plate. Both ends of the horizontal telescopic rod can extend and retract to adapt to the width of the steel strip. Both ends of the horizontal telescopic rod are rotatably connected to a rotating telescopic rod. The other end of the rotating telescopic rod can extend and retract freely and is fixedly connected to a grinding block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the coiling device for producing ultra-thin steel strip is reasonable and has the following advantages:

[0014] (1) The technical solution is to install a lifting device on the side of the steel strip winding machine. The lifting device is fixedly connected to the stress detection device. When the steel strip is winding, the lifting device will follow the radius of the steel strip wound on the winding roller to lift and lower, ensuring that the stress detection device is always directly above the steel coil and in contact with the steel coil, so that the steel strip is always detected for stress during the winding process. Once the stress exceeds the set threshold, the stress detection device will mark and remind, so that the staff will know when the steel coil just deforms and prepare for subsequent processing in time.

[0015] (2) The technical solution is to set up a burr grinding device on both sides of the stress detection device. The burr grinding device is equipped with a telescopic structure so that the steel strip passes through the burr grinding device before being wound by the winding machine. The burr grinding device will grind the burrs on both sides of the steel strip so that the burrs are removed when the steel strip is wound by the winding roller. This prevents the steel strip from deforming during winding due to the burrs on both sides, which would eventually cause stress release between the layers and lead to loose winding.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0026] Example 1:

[0027] A winding device for producing ultra-thin steel strip is provided, including a steel strip winding machine 1, a lifting device 2, a stress detection device 3, and a burr grinding device 4;

[0028] The lifting device 2 is vertically installed on one side of the steel strip winding machine 1. The lifting end of the lifting device 2 can move vertically up and down according to the different radii of the steel coil wound on the winding roller of the steel strip winding machine 1.

[0029] The stress detection device 3 is horizontally set and fixedly connected to the lifting end of the lifting device 2. The stress detection device 3 is always located at the center above the take-up roller. The stress detection device 3 includes a vertically movable arc plate 32 and a detection rod 35. The bottom surface of the arc plate 32 is always in contact with the outermost edge of the steel coil wound on the take-up roller of the steel strip take-up machine 1. The detection rod 35 is vertically set on the top surface of the arc plate 32. When the steel coil undergoes a slight deformation due to stress release, the outermost edge of the steel coil will drive the arc plate 32 to move vertically upward. The arc plate 32 will drive the detection rod 35 to move upward. The staff can check whether the stress of the steel coil is within the safe range by observing the detection rod 35.

[0030] The burr grinding device 4 is set on both sides of the stress detection device 3 and is used to grind the burrs on both sides of the steel strip before the steel strip is wound by the winding roller.

[0031] The lifting device 2 includes a vertical telescopic rod 21, a fixed rod 22, and a reinforcing rib 23. The vertical telescopic rod 21 is vertically installed on one side of the steel strip winding machine 1. The top of the vertical telescopic rod 21 can extend vertically upward as the number of steel coils wound on the winding roller of the steel strip winding machine 1 increases. The fixed rod 22 is horizontally installed and fixedly connected to the top of the vertical telescopic rod 21. The fixed rod 22 is fixedly connected to the stress detection device 3. The reinforcing rib 23 is used to strengthen the connection between the fixed rod 22 and the stress detection device 3.

[0032] The stress detection device 3 includes a connecting plate 31, an arc plate 32, and four lifting rods 33. The connecting plate 31 is horizontally arranged and fixedly connected to the fixed rod 22. A horizontal arc plate 32 is arranged below the connecting plate 31. The bottom surface of the arc plate 32 is arc-shaped. Through holes are provided at the four corners of the connecting plate 31. The bottom end of each lifting rod 33 passes through the through holes at the four corners of the connecting plate 31 and is fixedly connected to the top surface of the arc plate 32. The top end of the lifting rod 33 is always located above the connecting plate 31.

[0033] The bottom surface of the arc plate 32 is provided with several pulleys 37. The pulleys 37 are always in contact with the outermost part of the steel coil wound by the winding roller on the steel strip winding machine 1. The rotation direction of the pulleys 37 is the same as or opposite to the rotation direction of the winding roller on the steel strip winding machine 1.

[0034] Each lifting rod 33 has a vertical spring 34 installed on its outer side, and each spring 34 is located between the arc plate 32 and the connecting plate 31.

[0035] The stress detection system also includes two synchronization plates 36, the bottom surface of each synchronization plate 36 is fixedly connected to the top of the two lifting rods 33 respectively, so as to realize the synchronous movement of the lifting rods 33.

[0036] A vertical detection rod 35 is fixedly connected to the center of each synchronization plate 36. The bottom end of the detection rod 35 is located on the top surface of the arc plate 32. The other end of the detection rod 35 passes through the connecting plate 31 and extends out of the connecting plate 31. Two parallel grooves 351 are provided on the surface of the detection rod 35, and the two grooves 351 represent the maximum and minimum stress during the steel strip winding process, respectively.

[0037] The burr grinding device 4 includes a horizontal telescopic rod 41, a rotating telescopic rod 42, and a grinding block 43. The horizontal telescopic rod 41 is aligned with the axis of the winding roller on the steel strip winding machine 1. The top surface of the horizontal telescopic rod 41 is fixedly connected to the bottom surface of the connecting plate 31. Both ends of the horizontal telescopic rod 41 can extend and retract to accommodate the width of the steel strip. Both ends of the horizontal telescopic rod 41 are rotatably connected to the rotating telescopic rod 42. The other end of the rotating telescopic rod 42 can extend and retract freely and is fixedly connected to the grinding block 43.

[0038] Working principle: During use, after the ultra-thin steel strip is cold rolled into shape, the tension of the ultra-thin steel strip is eliminated by the tension device. After passing through the tension roller, the ultra-thin steel strip moves toward the winding roller. The operator can freely adjust the extension length of the horizontal telescopic rod 41 to adapt to the width of the ultra-thin steel strip, and can make the rotating telescopic rod 42 rotate around the connection between the rotating telescopic rod 42 and the horizontal telescopic rod 41 to adapt to the angle at which the ultra-thin steel strip is wound. Before the ultra-thin steel strip is wound by the winding roller on the steel strip winding machine 1, the burrs on both sides of the ultra-thin steel strip are removed by the grinding block 43.

[0039] After the steel strip is wound up by the winding roller on the steel strip winding machine 1, the operator can adjust the vertical telescopic rod 21 set on one side of the steel strip winding machine 1. As the ultra-thin steel strip is continuously wound up by the winding roller, the radius of the wound steel coil on the winding roller continuously increases, and the vertical telescopic rod 21 will also rise continuously, so that the pulley 37 on the stress detection device 3 always fits against the outermost side of the wound steel strip on the winding roller.

[0040] If the coiled steel experiences slight deformation due to stress accumulation, it will continuously push up the pulley 37, causing the arc plate 32 to move upward and compress the spring 34. During this process, the detection rod 35 will also rise. The detection rod 35 has two annular grooves 351 marked with different colors. The two grooves 351, from top to bottom, represent the minimum stress threshold and the maximum stress threshold, respectively. When the operator observes the groove 351 represented by the maximum stress threshold on the connecting plate 31, it indicates that the steel strip coiler 1 has experienced stress imbalance during the coiling of ultra-thin steel strip.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
