Description

Technical Field

[0001] This application relates to the field of steel strip production technology, and in particular to a steel strip winding device. Background Technology

[0002] In the field of steel strip production technology, steel strip production involves producing thin steel strips from thicker raw steel strips through rolling and physical and chemical surface treatments. The raw steel strips pass continuously through pre-set processing equipment to finally obtain thin steel strips that meet the requirements. Whether it's material collection after production within the plant or material transportation outside the plant, in order to save volume and avoid bending of the steel strip, it is usually necessary to coil the steel strip. A coiling mechanism is used to perform the coiling operation during the steel strip coiling process.

[0003] Related prior art, such as Chinese patent application "A Steel Strip Coiling Device", application number: CN202211265322.X, discloses a steel strip production equipment technology field, including a steel coil feeding mechanism. The steel coil feeding mechanism includes a drum base, a clip fixedly installed on the device base, a drum rotatably installed on the drum base, a steel coil fixedly installed on the drum, an electric cylinder frame fixedly installed on the device base, a shrinking electric cylinder fixedly installed on the electric cylinder frame, a pusher fixedly installed on the telescopic end of the shrinking electric cylinder, a slide rail fixedly installed on the device base, a sliding clip slidably installed on the slide rail, an upper clamp slidably installed on the sliding clip, a clamping plate fixedly installed on the upper clamp, a compression spring fixedly installed on the upper clamp, a moving motor fixedly installed on the sliding clip, a moving gear fixedly installed on the output shaft of the moving motor, upper and lower rails installed on the slide rail, and a moving rack fixedly installed on the slide rail.

[0004] In existing technologies, conveying relies solely on guide rollers without an active correction mechanism, resulting in issues such as strip misalignment and lateral deviation. The deviation amplifies with increasing roll diameter, causing the entire roll to exhibit "tower-shaped" or "bird's nest" defects. Subsequent uncoiling requires manual edge trimming and cutting, leading to a decrease in yield. Insufficient or weakened tension during strip winding results in the inner coil being too tight and the outer coil being too loose. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a steel strip winding device, which adds a steel strip conveying device to achieve precise centering, constant tension winding, and instant cutting, thereby significantly improving winding quality and work efficiency.

[0006] The technical solution adopted in this application is as follows: a steel strip winding device, including a steel strip conveying device, a steel strip winding device and a conveying trolley. The steel strip conveying device includes a frame, the end of the frame closer to the steel strip winding device is referred to as the first end, and the end of the frame farther away from the steel strip winding device is referred to as the second end. A centering component, a conveying component, a tensioning component, a cutting component and a roller component are sequentially installed on the frame from the first end to the second end. The steel strip passes through the centering component, the conveying component, the tensioning component, the cutting component and the roller component in sequence and is connected to the steel strip winding device. The steel strip winding device works to wind the steel strip into a steel strip roll. The conveying trolley works to drive the wound steel strip roll to move.

[0007] Compared with existing technologies, the advantages of this application lie in the fact that the steel strip is conveyed by a steel strip conveyor, which is adapted to the subsequent steel strip winding process. From the first end to the second end of the frame, the five functional components of centering, conveying, tensioning, cutting, and rollers are arranged sequentially on the same frame along the direction of the steel strip, forming a straight process path. The steel strip only needs to be threaded once to continuously complete all pre-treatment processes, reducing intermediate transfer or repositioning links, which reduces structural complexity and shortens the equipment footprint.

[0008] Specifically, the centering assembly first ensures that the centerline of the steel strip is aligned with the centerline of subsequent assemblies and the winding device, suppressing deviation at its source. The conveying and tensioning assemblies work in tandem to maintain a constant tension on the steel strip before winding, preventing loose winding or inner coil wrinkles. The cutting assembly, located after the tensioning assembly and before the roller assembly, immediately cuts the strip when the winding length reaches the set value, working in conjunction with the tensioning assembly's instantaneous tension maintenance to prevent the tail strip from springing back or scattering. After cutting, the roller assembly continues to support and guide the tail end of the steel strip, ensuring a smooth transition to the winding device and reducing end-face unevenness. After the steel strip winding device completes winding, no manual handling is required; the conveyor trolley can directly carry the steel strip roll and move it out of the workstation, achieving continuous operation of winding-unloading-transfer and reducing downtime.

[0009] In some embodiments of this application, the centering assembly includes a guide shaft, an adjusting shaft, and two sliders. The guide shaft and the adjusting shaft are arranged parallel to each other and both pass through the sliders. The guide shaft has two threaded sections on its surface, which are symmetrically arranged and have opposite thread directions. The two sliders are respectively installed at the two threaded sections and are threadedly connected to the adjusting shaft. Rotation of the adjusting shaft causes the two sliders to move away from or towards each other. Side rollers are mounted on the sliders. The steel strip passes through the middle of the side rollers, and the rotation of the adjusting shaft can achieve centering guidance for steel strips of different widths.

[0010] Specifically, one end of the adjusting shaft is connected to a hand crank, allowing the operator to rotate the adjusting shaft by rotating the hand crank, thereby adjusting the position of the side roller. The hand crank provides direct mechanical manual input, requiring no external power, making adjustment immediate and intuitive, and allowing for fine-tuning at any time during equipment operation, thus facilitating maintenance. This application also includes a centering component to regulate the position of the steel belt, preventing deviation.

[0011] By utilizing a bidirectional thread and slider design, the distance between the two rollers can be adjusted synchronously by rotating a single adjusting shaft, enabling rapid and symmetrical centering of steel strips of different widths. The structure is simple, the adjustment range is visible, and the repeatability is high.

[0012] In some embodiments of this application, the conveying assembly includes at least one set of pressure roller assemblies. The pressure roller assembly includes an upper pressure roller, a lower pressure roller, and two mounting seats on the left and right. The two ends of the upper pressure roller and the two ends of the lower pressure roller are movably mounted on the mounting seats. The upper pressure roller and the lower pressure roller are subjected to force at the mounting seats and can be adjusted up and down. A first pressure cylinder is provided on the mounting seat, and the output shaft of the first pressure cylinder is connected to the upper pressure roller.

[0013] A rotary motor is installed on one side of the frame, and the rotary motor is connected to the lower pressure roller. The rotary motor drives the lower pressure roller to rotate. The position of the upper pressure roller is fixed by a first pressure cylinder. The first pressure cylinder applies a certain pressure to the steel strip through the upper pressure roller, and the rotation of the lower pressure roller drives the steel strip to move. The first pressure cylinder has an adjustable clamping force to ensure that steel strips of different thicknesses can obtain stable frictional traction, and the pressure value can be quantitatively set, resulting in a constant conveying speed and a low slippage rate.

[0014] In some embodiments of this application, the tensioning assembly includes a lower pressure block disposed on the frame, an upper pressure block disposed above the lower pressure block, and a second pressure cylinder connected to the upper pressure block. The second pressure cylinder drives the upper pressure block to move closer to or away from the lower pressure block. The steel strip passes between the upper pressure block and the lower pressure block, and the second pressure cylinder drives the upper pressure block and the lower pressure block to act on the surface of the steel strip.

[0015] The tensioning assembly applies force to the passing steel strip, ensuring that the steel strip between the steel strip winding device and the tensioning assembly is stretched taut and straight, facilitating subsequent winding. A controllable tension zone is created before winding, keeping the steel strip in a taut and straight state at all times, preventing slack winding and uneven tension (loose inside, tight outside).

[0016] In some embodiments of this application, the top surface of the lower pressure block is wavy or sawtooth-shaped, and the bottom surface of the upper pressure block is adapted to the top surface of the lower pressure block, allowing the bottom surface of the upper pressure block and the top surface of the lower pressure block to fit completely together. Using a wavy or sawtooth-shaped outer surface to contact the steel strip effectively increases the frictional force between the upper and lower pressure blocks and the steel strip, thus tautning the steel strip.

[0017] Specifically, the upper and lower pressure blocks are made of wear-resistant materials. Wear-resistant materials directly improve the lifespan of the pressure blocks and reduce tension fluctuations and maintenance frequency caused by wear.

[0018] In some embodiments of this application, the cutting assembly includes a base and a punching cutter. The punching cutter is connected to a punching power cylinder, which drives the punching cutter to cut the steel strip located at the base downwards. The punching power cylinder provides instantaneous high energy, the cutter punches vertically, resulting in a clean cut with minimal burrs, and the cutting action is synchronized with the tension, preventing the tail end from springing back.

[0019] In some embodiments of this application, the roller assembly includes a base plate and an upper roller mounted on a frame. The upper roller is horizontally positioned above the base plate, and a gap exists between the upper roller and the base plate. The steel strip passes through the gap between the upper roller and the base plate. The gap between the roller and the base plate forms a guide channel, which provides horizontal support and limitation for the tail end of the steel strip after cutting, preventing the tail end from sagging or swaying to the side, and ensuring that the tail end smoothly enters the winding station.

[0020] In some embodiments of this application, a guide plate is rotatably mounted on the second end of the frame. The guide plate is rotatably connected to the frame, and its lower surface is connected to an inclined guide cylinder. When the output shaft of the guide cylinder extends, the guide plate is positioned parallel to the frame; when the output shaft retracts, the guide plate folds downwards to the side of the frame. The guide plate extends horizontally when needed, forming a transition bridge to reduce the suspended length of the steel belt; when not in use, it folds back for storage, saving space and avoiding interference with maintenance.

[0021] In some embodiments of this application, a transport rail is provided on the front side of the steel strip winding device, and the conveying trolley is installed on the transport rail. Under power drive, the conveying trolley will move along the transport rail; a shelf is installed above the conveying trolley, and the top surface of the shelf is V-shaped.

[0022] The V-shaped shelf utilizes gravity for self-centering, automatically centering the steel strip roll when placed on it, eliminating the need for additional clamping or manual adjustment, thus improving roll changing speed and centering accuracy.

[0023] In some embodiments of this application, the shelf is connected to a lifting assembly. The lifting assembly moves the shelf upward to support the steel strip roll. The moving conveyor trolley moves the steel strip roll on the shelf synchronously. Two baffles are connected to the left and right sides of the shelf via a rotating shaft. The two baffles are located at the two ends of the rotating shaft. The rotating shaft is hinged to a lateral cylinder. The lateral cylinder drives the rotating shaft to rotate. The rotation of the rotating shaft drives the baffles to rotate. The rotation of the baffles towards one side of the shelf acts on the outer periphery of the steel strip roll.

[0024] The lifting assembly first lifts the steel strip coil off the reel, and then the trolley transports it directly away, achieving automatic unloading without lifting equipment or manual intervention, thus shortening downtime. The side-driven cylinder baffle can hold the outer circumference of the coil during transportation, preventing the steel coil from unwinding or swaying radially, and improving transportation safety.

[0029] The present application will now be described in detail with reference to the accompanying drawings.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] A steel strip winding device, embodiment one as follows Figure 1 , Figure 2 As shown: It includes a steel strip conveying device 1, a steel strip winding device 2 and a conveying trolley 3. The steel strip conveying device 1 includes a frame 4. The end of the frame 4 closer to the steel strip winding device 2 is designated as the first end 4a, and the end of the frame 4 away from the steel strip winding device 2 is designated as the second end 4b. From the first end 4a to the second end 4b, a centering component 7, a conveying component 8, a tensioning component 9, a cutting component 10 and a roller component 11 are installed sequentially on the frame 4. The centering component 7 first ensures that the center line of the steel strip is aligned with the center line of the subsequent components and the winding device, suppressing deviation at the source; the conveying component 8 and the tensioning component 9 work together to keep the steel strip under constant tension before winding, avoiding loose winding or inner coil wrinkles; the cutting component 10 is located after the tensioning component 9 and before the roller component 11, and can immediately cut when the winding length reaches the set value, cooperating with the instantaneous tension maintenance of the tensioning component 9 to prevent the tail strip from springing back or scattering; the roller component 11 still provides support and guidance for the tail end of the steel strip after cutting, ensuring a smooth transition of the tail end to the winding device and reducing end face unevenness.

[0032] The steel strip sequentially passes through the centering assembly 7, conveying assembly 8, tensioning assembly 9, cutting assembly 10, and roller assembly 11, and connects to the steel strip winding device 2, forming a straight process path. The steel strip only needs to be threaded once to continuously complete all pre-treatment processes, reducing intermediate transfer or repositioning steps, thus lowering structural complexity and reducing equipment footprint. The steel strip winding device 2 winds the steel strip into a coil, and the conveying trolley moves the coiled steel strip. After winding, the steel strip winding device 2 eliminates the need for manual handling; the conveying trolley 3 can directly carry the steel strip coil and move it out of the workstation, achieving continuous operation of winding-unloading-transfer and reducing downtime.

[0033] Example 2, as Figures 1 to 4 As shown, the centering assembly 7 includes a guide shaft 12, an adjusting shaft 13, and two sliders 14. The guide shaft 12 and the adjusting shaft 13 are arranged parallel to each other, and both the guide shaft 12 and the adjusting shaft 13 pass through the sliders 14. The surface of the guide shaft 12 is provided with two threaded sections, which are symmetrically arranged left and right, and the threads of the two threaded sections are opposite in direction. The two sliders 14 are respectively installed at the two threaded sections, and the sliders 14 are threadedly connected to the adjusting shaft 13. The rotation of the adjusting shaft 13 causes the two sliders 14 to move away from or towards each other. A side roller 15 is installed on the slider 14. The steel strip passes through the middle of the side roller 15. The rotation of the adjusting shaft 13 can achieve centering and guidance for steel strips of different widths.

[0034] Specifically, one end of the adjusting shaft 13 is connected to a hand crank 16. The operator can rotate the adjusting shaft 13 by rotating the hand crank 16, thereby adjusting the position of the side roller 15. The hand crank provides direct mechanical manual input, requiring no external power. Adjustment is immediate and intuitive, and fine-tuning can be performed at any time during equipment operation, facilitating maintenance. This application also includes a centering component 7 to regulate the position of the steel belt and prevent deviation.

[0035] By utilizing a bidirectional thread and slider 14, the distance between the two rollers 15 can be adjusted synchronously by rotating a single adjusting shaft 13, enabling rapid and symmetrical centering of steel strips of different widths. The structure is simple, the adjustment range is visible, and the repeatability is high.

[0036] The conveying assembly 8 includes at least one set of pressure roller assemblies. The pressure roller assembly includes an upper pressure roller 18, a lower pressure roller 19, and two mounting seats 20 on the left and right. The two ends of the upper pressure roller 18 and the two ends of the lower pressure roller 19 are movably mounted on the mounting seats 20. The upper pressure roller 18 and the lower pressure roller 19 are subjected to force at the mounting seats 20 and can be adjusted up and down. A first pressure cylinder 21 is provided on the mounting seat 20, and the output shaft of the first pressure cylinder 21 is connected to the upper pressure roller 18.

[0037] A rotary motor 22 is installed on one side of the frame 4. The rotary motor 22 is connected to the lower pressure roller 19, and the rotary motor 22 drives the lower pressure roller 19 to rotate. The position of the upper pressure roller 18 is fixed by a first pressure cylinder 21. The first pressure cylinder 21 applies a certain pressure to the steel strip through the upper pressure roller 18, and the rotation of the upper pressure roller 18 drives the steel strip to move. The first pressure cylinder 21 has an adjustable clamping force to ensure that steel strips of different thicknesses can obtain stable frictional traction, and the pressure value can be quantitatively set, resulting in a constant conveying speed and a low slippage rate.

[0038] The tensioning assembly 9 includes a lower pressure block 23 disposed on the frame 4, and an upper pressure block 24 disposed above the lower pressure block 23. The upper pressure block 24 is connected to a second pressure cylinder 25. The second pressure cylinder 25 drives the upper pressure block 24 to move closer to or away from the lower pressure block 23. The steel strip passes between the upper pressure block 24 and the lower pressure block 23. The second pressure cylinder 25 drives the upper pressure block 24 and the lower pressure block 23 to act on the surface of the steel strip.

[0039] The tensioning component 9 applies force to the passing steel strip, ensuring that the steel strip between the steel strip winding device 2 and the tensioning component 9 is stretched taut and straight, facilitating subsequent winding. A controllable tension zone is formed before winding, ensuring the steel strip remains in a taut, straight state, preventing slack winding and uneven tension.

[0040] The top surface of the lower pressure block 23 is wavy or serrated, and the bottom surface of the upper pressure block 24 is adapted to the top surface of the lower pressure block 23, allowing them to fit completely together. The wavy or serrated outer surface in contact with the steel strip effectively increases the friction between the upper and lower pressure blocks 24 and the steel strip, thus tauting the steel strip. Specifically, the upper and lower pressure blocks 24 and 23 are made of wear-resistant material. Wear-resistant material directly improves the lifespan of the pressure blocks, reducing tension fluctuations and maintenance frequency caused by wear.

[0041] The cutting assembly 10 includes a base 26 and a punching cutter 27. The punching cutter 27 is connected to a punching power cylinder 28. The punching power cylinder 28 drives the punching cutter 27 to punch downwards and cut the steel strip located at the base 26. The punching power cylinder 28 provides instantaneous high energy, the cutter punches vertically, the cut is clean and the burrs are small, and the cutting action is synchronized with the tension, avoiding the tail end from springing back.

[0042] The roller assembly 11 includes a base plate 29 and an upper roller 30 mounted on the frame 4. The upper roller 30 is horizontally positioned above the base plate 29, and a gap exists between the upper roller 30 and the base plate 29. The steel strip passes through the gap between the upper roller 30 and the base plate 29. The gap between the roller and the base plate 29 forms a guide channel, which provides horizontal support and limit to the tail end of the steel strip after cutting, preventing the tail end from sagging or swaying to the side, and ensuring that the tail end smoothly enters the winding station.

[0043] A guide plate 31 is rotatably mounted on the second end 4b of the frame 4. The guide plate 31 is rotatably connected to the frame 4. The lower surface of the guide plate 31 is connected to an inclined guide cylinder 32. When the output shaft of the guide cylinder 32 extends, the guide plate 31 is positioned parallel to the frame 4. When the output shaft of the guide cylinder 32 retracts, the guide plate 31 folds downward to the side of the frame 4. The guide plate 31 extends horizontally when needed to form a transition bridge, reducing the length of the steel belt suspended in the air. When not in use, it is folded and stored to save space and avoid interference with maintenance.

[0044] The rest of the contents of Example 2 are the same as those of Example 1.

[0045] Example 3, as Figures 1 to 4 As shown, a transport track 33 is provided on the front side of the steel strip winding device 2, and the conveying trolley 3 is installed on the transport track 33. Under power drive, the conveying trolley 3 will move along the transport track 33; a support plate 34 is installed above the conveying trolley 3, and the top surface of the support plate 34 is V-shaped. The V-shaped support plate 34 uses gravity for self-centering, and the steel strip roll is automatically centered when placed on it, without the need for additional clamping or manual adjustment, thereby improving the roll changing speed and centering accuracy.

[0046] The support plate 34 is connected to the lifting assembly 35. The lifting assembly 35 moves the support plate 34 upwards to support the steel strip coil. The movement of the conveying trolley moves the steel strip coil on the support plate 34 synchronously. Two baffles 37 are connected to both sides of the support plate 34 via a rotating shaft 36. The two baffles 37 are located at both ends of the rotating shaft 36. The rotating shaft 36 is hinged to a lateral cylinder 38. The lateral cylinder 38 drives the rotating shaft 36 to rotate, which in turn rotates the baffles 37. The rotation of the baffles 37 towards one side of the support plate 34 acts on the outer circumference of the steel strip coil. The lifting assembly 35 first lifts the steel strip coil off the shaft, and then the trolley directly transports it away, achieving automatic unloading without lifting equipment or manual intervention, thus shortening downtime. The baffles 37 driven by the lateral cylinder 38 can hold the outer circumference of the coil during transportation, preventing the steel coil from unwinding or radially swaying, improving transportation safety.

[0047] The other contents of Example 3 are the same as those of Example 1 or Example 2.
