Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically to a steel strip processing traction device. Background Technology

[0002] During production and transportation, steel strip is usually in the form of steel coils. When cutting is required later, the steel coil is unrolled and fed into cutting equipment to obtain the desired product. However, steel coils are relatively heavy, and a traction device is needed to smoothly pull the coil open and feed the steel strip into the cutting equipment. Therefore, the traction device is a key structure in the steel strip processing stage.

[0003] Currently, existing steel strip processing traction devices on the market, such as the traction device for ultra-thin steel strip processing disclosed in patent CN219058049U, are used for traction of ultra-thin steel strips and can also adapt to the traction of some thin steel strips. A first fixed plate is fixedly connected to the surface of the platform, a first traction roller is rotatably connected to the inner wall of the first fixed plate, a second traction roller is rotatably connected to the inner wall of the first fixed plate, a first anti-slip silicone grain is fixedly connected to the surface of the first traction roller, a second anti-slip silicone grain is fixedly connected to the surface of the second traction roller, a limit plate is fixedly connected to the surface of the platform, a rubber roller is rotatably connected to the inner wall of the limit plate, and a transmission mechanism is provided on the platform surface and is poweredly connected to the first and second traction rollers. In use, the steel strip is placed between the first and second traction rollers. The motor of the transmission mechanism drives the first and second traction rollers to rotate via a double-sided toothed synchronous belt, a first driven synchronous pulley, and a second driven synchronous pulley. The steel strip is clamped and pulled onto the rubber roller by the first and second anti-slip silicone granules. The rotating rubber roller carries the steel strip and moves it, achieving the goal of protecting and traction the ultra-thin steel strip. This avoids the problem of steel strip deformation caused by using hard traction rollers in the transmission traction device, and prevents scratches on the steel strip surface. Although the above traction device can achieve the traction and conveying of thin steel strips, it relies solely on anti-slip silicone granules for clamping and conveying. While this can prevent deformation and scratches during traction, for heavy steel coils requiring greater traction force, the soft anti-slip silicone granules still have room for deformation, causing slippage between the silicone granules and the steel strip, thus affecting the effectiveness of traction. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a steel strip processing traction device. An upper anti-slip silicone sleeve and a lower anti-slip silicone sleeve are fitted around the upper and lower roller shafts, respectively. Upper and lower anti-slip silicone granules are respectively provided on the upper and lower anti-slip silicone sleeves. These granules are staggered along the axial direction of the upper or lower roller shaft. This arrangement ensures that when the steel strip passes over the granules, the forces exerted on the steel strip by the granules are vertically offset, resulting in minimal elastic deformation of the steel strip. This creates an approximately wavy structure in the conveying direction and along the axial direction of the upper and lower roller shafts. The uneven portions formed by the elastic deformation interlock with the upper and lower anti-slip silicone granules to achieve anti-slip.

[0005] The specific technical solution is as follows:

[0006] A steel strip processing traction device includes a frame, an upper roller shaft, a lower roller shaft, and a driver. The upper and lower roller shafts are arranged parallel and spaced apart, and are distributed vertically in upper and lower layers. Both ends of the upper and lower roller shafts are rotatably mounted on the frame. The driver is mounted on the frame and is poweredly connected to the upper and / or lower roller shafts. The device further includes an upper anti-slip silicone sleeve and a lower anti-slip silicone sleeve, which are respectively fitted over the upper and lower roller shafts. The outer walls of the upper and lower anti-slip silicone sleeves are respectively provided with protruding upper and lower anti-slip silicone particles, which are staggered along the axial direction of the upper or lower roller shaft. The sum of the lengths of the upper and lower anti-slip silicone particles is greater than the interval between the outer walls of the upper and lower anti-slip silicone sleeves.

[0007] In the aforementioned steel strip processing traction device, the outer walls of both the upper and lower roller shafts are provided with several limiting grooves along their own axial direction, and the inner walls of both the upper and lower anti-slip silicone sleeves are provided with limiting strips corresponding to the limiting grooves.

[0008] The aforementioned steel strip processing traction device further includes a reinforcing component, which is disposed on the frame and located below the lower roller shaft. The reinforcing component contains friction-enhancing material, and when the lower roller shaft rotates, the lower anti-slip silicone particles contact the friction-enhancing material.

[0009] The aforementioned steel strip processing traction device includes a reinforcing component comprising a storage box, a lifting plate, a vibrator, and an adjusting locking element. The storage box has an upper opening and a lower opening, and is arranged along the length of the lower roller shaft and located below the lower roller shaft. The lower part of the lower anti-slip silicone sleeve extends into the upper opening of the storage box. The lifting plate is installed in the lower opening of the storage box, and an annular bellows cover is installed between the lifting plate and the lower opening of the storage box. Meanwhile, a bracket is installed between the storage box and the frame, and an adjusting groove is opened on the bracket along the vertical direction. An adjusting locking element is installed in the adjusting groove, and one end of the adjusting locking element extends to the bottom of the lifting plate and abuts against it. Furthermore, a vibrator is installed between the lifting plate and the frame.

[0010] The aforementioned steel strip processing traction device includes an adjusting locking component comprising a pin, a telescopic block, and a telescopic spring. A plurality of locking holes are spaced vertically on the inner wall of the adjusting groove. The middle portion of the pin passes through the adjusting groove. An insertion hole is provided on the side wall of one end of the pin located within the adjusting groove. A telescopic spring is installed in the insertion hole. The telescopic block is positioned at the opening of the insertion hole and abuts against the telescopic spring. The other end of the telescopic block extends into one of the locking holes.

[0011] In the aforementioned steel strip processing traction device, the friction-enhancing material is anti-slip magnesium powder.

[0012] The aforementioned steel strip processing traction device further includes a powder wiping assembly, which is mounted on the frame and positioned behind the reinforcing assembly along the conveying direction of the steel strip.

[0013] The aforementioned steel strip processing traction device includes a powder-wiping assembly comprising a pressure plate, a brush, and an adjusting frame. The adjusting frame is mounted on the machine frame. The pressure plate is horizontally positioned above the steel strip and arranged parallel to the upper roller shaft. Simultaneously, the pressure plate is mounted on the adjusting frame, and the brush is located at the bottom of the pressure plate and faces the steel strip, covering the length direction of the pressure plate.

[0014] The aforementioned steel strip processing traction device includes an adjusting frame comprising a screw, a threaded sleeve, and a floating spring. A through hanging hole is provided on the frame along the vertical direction. The upper end of the screw has a limit head and is rotatably installed in the hanging hole. The lower end of the screw is threadedly connected to the upper end of the threaded sleeve. A floating spring is connected to the lower end of the threaded sleeve, and the lower end of the floating spring is connected to the pressure plate.

[0015] The positive effects of the above technical solution are:

[0016] The aforementioned steel strip processing traction device, by respectively installing upper and lower anti-slip silicone sleeves on the upper and lower roller shafts, and simultaneously providing upper and lower anti-slip silicone granules on the outer walls of the upper and lower anti-slip silicone sleeves, and staggering the upper and lower anti-slip silicone granules along the axial direction of the upper or lower roller shaft, allows the forces exerted by the upper and lower anti-slip silicone granules on the steel strip to be misaligned in the vertical direction. This enables the steel strip to form a minimal elastic deformation with uneven surfaces. The anti-slip effect is enhanced by the interlocking of the deformed parts with the upper and lower anti-slip silicone granules, thereby preventing slippage during traction and improving the reliability and effectiveness of traction.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0022] Figure 1 This is a structural diagram of an embodiment of a steel strip processing traction device according to this utility model. Figure 1As shown, the steel strip processing traction device provided in this embodiment includes: a frame 1, an upper roller shaft 2, a lower roller shaft 3, and a driver. The upper roller shaft 2, lower roller shaft 3, and driver are mounted on the frame 1. The upper roller shaft 2 and lower roller shaft 3 are arranged parallel and spaced apart, vertically arranged in upper and lower layers with a gap between them to facilitate the steel strip passing through the gap. Furthermore, both ends of the upper roller shaft 2 and lower roller shaft 3 are rotatably mounted on the frame 1, and a reduction gearbox is connected to the driver. The reduction gearbox is poweredly connected to the upper roller shaft 2 and / or lower roller shaft 3, thereby driving the upper roller shaft 2 and / or lower roller shaft 3 to rotate actively, providing power for the subsequent traction of the steel strip. It is worth noting that a coupling can be installed between the output shaft of the driver and the input shaft of the reduction gearbox, and the output shaft of the reduction gearbox can be connected to the upper roller shaft 2 and / or lower roller shaft 3 by a belt or a chain. Various connection methods are common technologies in the transmission field, and their specific structures will not be described in detail here.

[0023] Specifically, upper anti-slip silicone sleeves 4 and 5 are respectively fitted over the upper roller shaft 2 and lower roller shaft 3, making the upper roller shaft 2 and lower roller shaft 3 rubber-coated roller shafts to prevent damage to the steel strip surface when pressing it. At the same time, protruding upper anti-slip silicone particles 41 and lower anti-slip silicone particles 51 are respectively provided on the outer wall of the upper anti-slip silicone sleeve 4 and lower anti-slip silicone sleeve 5. The upper anti-slip silicone particles 41 and lower anti-slip silicone particles 51 contact the steel strip surface to achieve direct contact with the steel strip surface, thereby pulling the steel strip to move. Furthermore, the upper anti-slip silicone granules 41 and 51 are staggered along the axial direction of the upper roller shaft 2 or the lower roller shaft 3. This allows the forces exerted by the upper and lower anti-slip silicone granules 41 on the steel strip to be staggered in the vertical direction. This results in a slightly uneven and minimal elastic deformation along both the length and width of the steel strip when it is pressed, creating an approximately wave-like structure. The upper and lower anti-slip silicone granules 41 and 51 are positioned within their corresponding uneven portions, achieving mutual locking and preventing slippage. Moreover, the sum of the lengths of the upper and lower anti-slip silicone granules 41 and 51 is greater than the gap between the outer walls of the upper and lower anti-slip silicone sleeves 4 and 5. This ensures that when the steel strip passes through the gap between the upper and lower anti-slip silicone granules 41 and 51, the upper and lower anti-slip silicone granules 41 and 51 ensure minimal elastic deformation when pressing down on the steel strip, resulting in a more rational structural design.

[0024] More specifically, several limiting grooves 21 are formed along their axial direction on the outer walls of both the upper roller shaft 2 and the lower roller shaft 3. Simultaneously, limiting strips 42, corresponding to the limiting grooves 21, are provided on the inner walls of both the upper anti-slip silicone sleeve 4 and the lower anti-slip silicone sleeve 5. This allows the upper anti-slip silicone sleeve 4 and the lower anti-slip silicone sleeve 5 to be fitted onto the upper roller shaft 2 and the lower roller shaft 3 respectively, so that the limiting strips 42 can engage with the corresponding limiting grooves 21 to achieve positioning, preventing circumferential displacement between them. This ensures that the upper roller shaft 2 and the lower roller shaft 3 can smoothly drive the upper anti-slip silicone sleeve 4 and the lower anti-slip silicone sleeve 5 to rotate, preventing slippage. Furthermore, when rolling thicker steel strips, the gap between the upper roller shaft 2 and the lower roller shaft 3 can be further reduced, allowing the upper anti-slip silicone sleeve 4 and the lower anti-slip silicone sleeve 5 to directly contact and press against the surface of the steel strip. Combined with the action of the upper anti-slip silicone granules 41 and the lower anti-slip silicone granules 51, friction is further increased, improving traction effectiveness.

[0025] Figure 2 This is a structural diagram of the enhancement component according to a preferred embodiment of the present invention. Figure 1 and Figure 2 As shown, it also includes a reinforcing component 6, which is mounted on the frame 1 and located below the lower roller shaft 3. This allows the reinforcing component 6 to act on the lower anti-slip silicone particles 51 outside the lower roller shaft 3, increasing the friction coefficient of the lower anti-slip silicone particles 51 and further increasing the friction with the steel strip. Additionally, a friction-enhancing material is provided inside the reinforcing component 6. When the lower roller shaft 3 rotates, the lower anti-slip silicone particles 51 contact the friction-enhancing material. That is, when the lower roller shaft 3 rotates and the lower anti-slip silicone particles 51 pass through the reinforcing component 6, the friction-enhancing material can contact and cover the lower anti-slip silicone particles 51, thereby increasing the surface friction of the lower anti-slip silicone particles 51.

[0026] More specifically, the reinforcing component 6 includes a storage box 61, a lifting plate 62, a vibrator 63, and an adjusting locking component 64. The storage box 61 has an upper opening and a lower opening, meaning it is a through-type structure. The storage box 61 is a frame structure, providing conditions for the subsequent connection of the lower roller shaft 3 and the lifting plate 62 to the storage box 61. Furthermore, the storage box 61 is arranged along the length of the lower roller shaft 3 and located below it. Simultaneously, the lower part of the lower anti-slip silicone sleeve 5 extends into the upper opening of the storage box 61, allowing the lower anti-slip silicone particles 51 on the lower anti-slip silicone sleeve 5 to enter the storage box 61 when the lower roller shaft 3 rotates. Additionally, a lifting plate 62 is provided in the lower opening of the storage box 61. The height of the bottom of the storage box 61 can be adjusted by raising the lifting plate 62, ensuring continued contact between the friction-enhancing material and the lower anti-slip silicone particles 51 after the friction-enhancing material is worn out. In addition, an annular bellows cover is provided between the lower opening of the lifting plate 62 and the storage box 61. The annular bellows cover can cover the gap between the lower opening of the storage box 61 and the lifting plate 62, while also meeting the lifting and lowering requirements of the lifting plate 62 relative to the storage box 61, and can also accommodate the vibration requirements of the lifting plate 62 itself. At the same time, a bracket 65 is provided between the storage box 61 and the frame 1, that is, the storage box 61 is supported below the lower roller shaft 3 by the bracket 65. In addition, an adjustment groove 651 is provided on the bracket 65 along the vertical direction, and an adjustment locking member 64 is provided in the adjustment groove 651. By adjusting the sliding of the locking member 64 in the adjustment groove 651, the height of the locking member 64 in the vertical direction can be changed, providing conditions for the subsequent adjustment of the height of the lifting plate 62. At this time, one end of the adjusting locking member 64 extends to the bottom of the lifting plate 62 and abuts against it. That is, the adjusting locking member 64 supports the lifting plate 62, so that the lifting plate 62 can maintain its height during use. When it is necessary to raise or lower, it can be achieved by adjusting the sliding of the adjusting locking member 64 in the adjusting groove 651. The structure is simple and more flexible. In addition, a vibrator 63 is also provided between the lifting plate 62 and the frame 1. At this time, the vibrator 63 is installed on the frame 1, and the vibrating part of the vibrator 63 is connected to the lifting plate 62. Preferably, the vibrator 63 is a voice coil motor, which can realize the vibration of the lifting plate 62 when it is working. Since each time the anti-slip silicone granule 51 passes through the friction-enhancing material, it will leave grooves on the friction-enhancing material, resulting in a reduction or absence of the friction-enhancing material contacted by subsequent anti-slip silicone granules 51. Therefore, it is necessary to drive the lifting plate 62 to vibrate by the vibrator 63 to smooth out the grooves on the friction-enhancing material and ensure that each anti-slip silicone granule 51 can smoothly contact the friction-enhancing material. Preferably, the upper opening of the storage box 61 is provided with clearance holes on both sides corresponding to the lower anti-slip silicone granules 51. This can minimize the gap between the edge of the upper opening of the storage box 61 and the surface of the lower anti-slip silicone sleeve 5, reduce the diffusion of friction-enhancing materials, and ensure that the lower anti-slip silicone granules 51 can smoothly enter and exit the storage box 61, resulting in a more reasonable structural design.It is worth noting that the lifting adjustment of the locking component 64 is adjusted at regular intervals. The specific adjustment interval depends on the actual usage of the friction-enhancing material. If the friction-enhancing material is consumed quickly, the adjustment is more frequent, and vice versa.

[0027] More specifically, the adjusting locking component 64 for adjusting the height of the lifting plate 62 includes a pin 641, a telescopic block, and a telescopic spring. At this time, a number of locking holes are provided on the inner wall of the adjusting groove 651 at intervals along the vertical direction, and the middle part of the pin 641 is inserted into the adjusting groove 651, so that the pin 641 can pass through different locking holes in sequence when it moves in the vertical direction. In addition, a insertion hole is provided on the side wall of one end of the pin 641 located in the adjustment groove 651, and a telescopic spring is installed in the insertion hole. The telescopic block is placed at the opening of the insertion hole and abuts against the telescopic spring. The other end of the telescopic block extends into one of the locking holes. When the pin 641 is raised or lowered, an external force is applied to the pin 641, causing the telescopic block to retract and disengage from the current locking hole. When it moves to the lower locking hole, it automatically locks into the corresponding locking hole under the action of the telescopic spring. This realizes the adjustment and temporary fixation of the pin 641 in different positions within the adjustment groove 651, meeting the usage requirements of adjusting the height of the lifting plate 62 and temporarily maintaining the height of the lifting plate 62. It is worth noting that the end of the telescopic block that extends into the locking hole is a conical surface. Under the application of a large force to the pin 641, the telescopic block retracts through the cooperation between the conical surface and the opening of the locking hole. The structure is simple and the operation is convenient. Preferably, the cross-section of the pin 641 is rectangular to prevent the telescopic block and the locking hole from deviating due to rotation of the pin 641 during use. In addition, a limiting piece 643 is provided on the side of the pin 641 near the lifting plate 62, and a locking nut 642 is provided on the side of the pin 641 located on the bracket 65 away from the limiting piece 643. The locking nut 642 and the limiting piece 643 limit the movement of the pin 641 in the length direction, which also prevents the telescopic block and the locking hole from deviating, maintains the installation stability of the adjusting locking member 64 in the adjusting groove 651, and avoids slippage during use.

[0028] More specifically, the preferred friction-enhancing material is anti-slip magnesium powder, whose main component is magnesium carbonate. It is chemically stable, non-corrosive, and will not damage the steel strip or the equipment itself. By increasing the coefficient of friction on the surface of the lower anti-slip particles, it enhances the friction between the particles and the steel plate, further improving the anti-slip effect. Furthermore, anti-slip magnesium powder can be purchased commercially, resulting in lower operating costs.

[0029] Figure 3 This is a structural diagram of a powder-applying assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 3As shown, a wiping component 7 is also provided on the frame 1. Along the conveying direction of the steel belt, the wiping component 7 is located behind the reinforcing component 6. That is, the wiping component 7 removes the friction-increasing material on the steel belt after traction, maintains the cleanliness of the steel belt surface, and eliminates the influence of the friction-increasing material on the steel belt.

[0030] More specifically, the wiping assembly 7 includes a pressure plate 71, a brush 72, and an adjusting frame 73. The adjusting frame 73 is mounted on the frame 1, and the pressure plate 71 is placed horizontally above the steel strip and parallel to the upper roller shaft, ensuring that the pressure plate 71 completely covers the steel strip in the width direction, thus providing conditions for thoroughly removing residual friction-enhancing materials from the steel strip. Simultaneously, the pressure plate 71 is mounted on the adjusting frame 73, and the brush 72 is positioned at the bottom of the pressure plate 71 and facing the steel strip, covering the length direction of the pressure plate 71. This allows the brush 72 to sweep away residual friction-enhancing materials from the steel strip as it passes under the wiping assembly 7, meeting the cleaning requirements.

[0031] More specifically, the adjusting bracket 73 for mounting the pressure plate 71 includes a screw 731, a threaded sleeve 732, and a floating spring. At this time, a through hanging hole is provided on the frame 1 in the vertical direction. Meanwhile, the upper end of the screw 731 is equipped with a limiting head, and the lower end of the screw 731 extends downward after passing through the hanging hole. The limiting head abuts against the opening of the hanging hole, thereby limiting the screw 731 in the vertical direction. The screw 731 can rotate freely in the hanging hole, providing conditions for subsequent tightening of the screw 731. In addition, the lower end of the screw 731 is threadedly connected to the upper end of the threaded sleeve 732, which allows the height of the threaded sleeve 732 to be adjusted when the screw 731 is turned. At the same time, a floating spring is connected to the lower end of the threaded sleeve 732, and the lower end of the floating spring is connected to the pressure plate 71. The floating spring provides a large floating space for the pressure plate 71, so that the brush 72 can adaptively adjust when it comes into contact with steel strips of different thicknesses, improving its adaptability in unexpected situations and providing higher safety assurance.

[0032] The steel strip processing traction device provided in this embodiment includes a frame 1, an upper roller shaft 2, a lower roller shaft 3, and a driver. The upper roller shaft 2 and the lower roller shaft 3 are rotatably mounted on the frame 1 in both upper and lower layers and are powered by the driver. At the same time, the upper roller shaft 2 and the lower roller shaft 3 are respectively fitted with an upper anti-slip silicone sleeve 4 with upper anti-slip silicone particles 41 and a lower anti-slip silicone sleeve 5 with lower anti-slip silicone particles 51. Furthermore, along the axial direction of the upper roller shaft 2 or the lower roller shaft 3, the upper anti-slip silicone particles 41 and the lower anti-slip silicone particles 51 are staggered, so that the force exerted by the upper anti-slip silicone particles 41 and the lower anti-slip silicone particles 51 on the steel strip when pressing the steel strip is staggered in the vertical direction. This allows the steel strip to undergo minimal elastic deformation to form a concave-convex structure. The concave-convex parts interlock with the upper anti-slip silicone particles 41 and the lower anti-slip silicone particles 51 to enhance the anti-slip effect, effectively preventing slippage during traction and improving traction reliability and effectiveness.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
