Description

Technical Field

[0001] This utility model belongs to the field of steel strip processing technology, specifically relating to a steel strip uncoiling and positioning device. Background Technology

[0002] In steel processing, automobile manufacturing, and home appliance production, steel strip is a core raw material that needs to be uncoiled by an uncoiler before subsequent processing such as shearing, stamping, and welding. The steel strip uncoiling positioning device is a crucial piece of equipment ensuring the stability of the uncoiling process. Its core function is to use two sets of symmetrically arranged positioning mechanisms to limit and guide the steel strip from both sides, preventing deviation, wrinkling, or edge damage during high-speed uncoiling, thus ensuring the accuracy and efficiency of subsequent processing steps. For example, in automobile body steel sheet processing, if the steel strip is misaligned during uncoiling, it will lead to dimensional deviations in the stamped parts, directly affecting the assembly accuracy of the car body. In home appliance casing production, steel strip misalignment can also cause raw material waste and increase production costs.

[0003] An existing steel strip uncoiling and positioning device has been found to be cumbersome to use when adapting to steel strips of different widths. Workers must first loosen the fixing bolts at the bottom of the positioning mechanism one by one with a wrench, then manually push the positioning mechanism along the slide rail to the target position. During this process, it is necessary to repeatedly measure whether the distance between the two sets of positioning mechanisms matches the width of the steel strip. After confirmation, all bolts are then tightened to complete the fixing. This adjustment method is cumbersome and cannot be adjusted quickly, resulting in poor practicality.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a steel strip uncoiling and positioning device to solve the technical problems mentioned in the background art, such as cumbersome spacing adjustment and poor adaptability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A steel strip uncoiling and positioning device includes two sets of positioning mechanisms. A sliding mechanism is commonly provided at the bottom of both sets of positioning mechanisms. Each sliding mechanism includes two sets of first mounting brackets. One set of positioning mechanisms has a first connecting seat at its bottom, and the other set has a second connecting seat at its bottom. First mounting brackets are provided on both the front and rear sides of the bottom of each first connecting seat. A fixing block is provided at the right end of each set of first mounting brackets. Guide components are provided at the top and bottom of each set of fixing blocks. Second mounting brackets are slidably mounted on the outer sides of each set of fixing blocks via the guide components. The front and rear sides of the bottom of each second connecting seat are respectively connected to the top of the corresponding set of second mounting brackets. A driving mechanism is commonly provided at one end of each set of second mounting brackets.

[0007] Furthermore, the driving mechanism includes a drive motor, a fixing plate is provided between the two sets of first mounting brackets, the drive motor is provided at the left end of the fixing plate, and a mounting block is provided on the right side of the opposite end of the two sets of fixing blocks. A connecting screw is rotatably provided at the left end of the mounting block, and the left end of the connecting screw passes through the fixing plate and connects to the right output end of the drive motor. A threaded cylinder is threadedly connected to the outer side of the connecting screw. A connecting plate is provided between the two sets of second mounting brackets, the connecting plate is provided with a reserved hole, and the inner side of the reserved hole of the connecting plate is connected to the outer side of the threaded cylinder. A protective component is provided on the top of the fixing plate and the top of the connecting plate. The automated adjustment method of the threaded transmission driven by the drive motor replaces manual operation, realizing rapid synchronous adjustment of the spacing of the positioning mechanism. The threaded transmission has precise positioning and self-locking functions. After adjustment, the spacing can be kept stable without additional fixing, avoiding positioning offset caused by uneven bolt tightening and improving the positioning accuracy when the steel strip is uncoiled.

[0008] Furthermore, the protective component includes a baffle and two sets of positioning screws. First positioning rods are provided on both the front and rear sides of the top of the fixed plate, and second positioning rods are provided on both the front and rear sides of the top of the connecting plate. Slots are provided at both the front and rear ends of the left side of the bottom of the baffle. The two sets of baffle slots are respectively engaged with the corresponding set of first positioning rods. Sliding holes are provided on both the front and rear sides of the right side of the bottom of the baffle. Sliding blocks are slidably installed within the sliding holes of both sets of baffles. The bottoms of the two sets of sliding blocks are respectively fitted with the tops of the corresponding set of second positioning rods. Threaded holes are provided through the two sets of sliding blocks and the corresponding second positioning rods. The outer sides of the two sets of positioning screws are threadedly connected to the sliding blocks and second positioning rods through the threaded holes. The cooperation between the sliding blocks and the sliding holes allows the protective component to move synchronously with the connecting plate, ensuring that the drive mechanism is always in a protected state during the spacing adjustment process, reducing dust wear on the transmission components. The locking function of the positioning screws can fix the position of the protective component after adjustment, preventing it from shifting due to vibration, while also facilitating quick unlocking during adjustment without affecting the spacing adjustment efficiency.

[0009] Furthermore, the guiding assembly includes four sets of guide blocks. Each of the two sets of fixed blocks has a sliding groove at its top and bottom right ends. Guide blocks are slidably disposed within the sliding grooves of all four sets of fixed blocks. The upper and lower ends of the inner sides of the two sets of second mounting brackets are respectively connected to the other end of the corresponding set of guide blocks. The precise guiding effect of the guide blocks and sliding grooves ensures the stability of the sliding trajectory of the second mounting bracket, keeps the two positioning mechanisms parallel at all times, improves the accuracy of spacing adjustment, ensures smooth spacing adjustment, and enhances operational convenience.

[0010] Furthermore, each of the two sets of first mounting brackets is equipped with a support base at the bottom, each of the two sets of fixed blocks is equipped with a support base on the right side of the bottom, and each of the two sets of second mounting brackets is equipped with a roller; this enhances the overall stability of the device, the rollers significantly reduce the sliding resistance of the second mounting brackets, and the four sets of support bases are evenly distributed to ensure the device is balanced under force, adapting to different site installation requirements and improving the applicability of the device.

[0011] Furthermore, both sets of positioning screws are equipped with rotating disks at their tops; the rotating disks reduce the difficulty of operation, improve the convenience of locking and unlocking the protective components, and can be operated without additional tools, avoiding adjustment obstruction caused by tool loss or site limitations, and adapting to the needs of rapid production line switching.

[0012] Furthermore, all four sets of support bases are equipped with anti-slip pads at their bottoms; the anti-slip function of the anti-slip pads ensures that the device remains stable during long-term uncoiling operations and frequent spacing adjustments, avoiding positioning deviations caused by device displacement and improving the processing quality of steel strips.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a drive mechanism to slide the second mounting bracket to adjust the spacing of the positioning mechanism, replacing the cumbersome manual pushing and bolt fixing methods of the past. This significantly shortens the spacing adjustment time. The guide component ensures that the second mounting bracket slides smoothly, avoiding spacing deviation caused by positioning mechanism offset, ensuring adjustment accuracy, and preventing the steel strip from running off track when uncoiling. The two sets of positioning mechanisms are connected to the corresponding mounting brackets through the first and second connecting seats, respectively. The structure is stable and can adapt to the high-frequency spacing switching requirements, improving the processing flexibility of the production line for multi-specification steel strips and reducing downtime.

[0016] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example See appendix Figure 1-5 A steel strip uncoiling and positioning device, comprising: Two sets of positioning mechanisms 1 are provided with a sliding mechanism at the bottom of both sets of positioning mechanisms 1. The sliding mechanism includes two sets of first mounting brackets 2. One set of positioning mechanisms 1 is provided with a first connecting seat 3 at the bottom, and the other set of positioning mechanisms 1 is provided with a second connecting seat 4 at the bottom. The first connecting seat 3 is provided with first mounting brackets 2 on both the front and rear sides of its bottom. The right end of each set of first mounting brackets 2 is provided with a fixing block 6. The top and bottom of each set of fixing blocks 6 are provided with guide components. The outer sides of each set of fixing blocks 6 are slidably provided with second mounting brackets 5 through the guide components. The front and rear sides of the bottom of the second connecting seat 4 are respectively connected to the top of the corresponding set of second mounting brackets 5. The two sets of second mounting brackets 5 are provided with a driving mechanism at opposite ends.

[0018] When adapting to steel strips of different widths, the drive mechanism of the two sets of second mounting brackets 5, which are set at opposite ends, is activated. The drive mechanism drives the two sets of second mounting brackets 5 to slide along the guide component on the outside of the fixed block 6. The top of the second mounting bracket 5 is connected to the front and rear sides of the bottom of the second connecting seat 4. The second connecting seat 4 moves synchronously with the second mounting bracket 5, thereby driving a set of positioning mechanisms 1 connected to it to move. At the same time, another set of positioning mechanisms 1 is fixed to the two sets of first mounting brackets 2 through the first connecting seat 3. The distance between the two sets of positioning mechanisms 1 is gradually adjusted to match the width of the steel strip as the second mounting bracket 5 slides. The guide component restricts the movement trajectory of the second mounting bracket 5 during its sliding process to prevent the second mounting bracket 5 from deviating and ensure that the two sets of positioning mechanisms 1 always remain parallel. After the adjustment is in place, the drive mechanism is turned off to complete the positioning distance adjustment.

[0019] More specifically, when the second mounting bracket 5 slides along the fixed block 6, the guide blocks 18 connected to the upper and lower ends of the inner side of the second mounting bracket 5 slide synchronously along the slide grooves at the top and bottom right ends of the fixed block 6. The guide blocks 18 are always in close contact with the inner wall of the slide groove, restricting the sliding direction of the second mounting bracket 5 and preventing the second mounting bracket 5 from shifting left or right or tilting during the sliding process. When the drive mechanism moves the second mounting bracket 5, the sliding of the guide blocks 18 in the slide groove provides stable guidance for the second mounting bracket 5, ensuring that the two sets of second mounting brackets 5 move synchronously, thereby driving the second connecting seat 4 and the positioning mechanism 1 to move smoothly, and avoiding uneven spacing between the two sets of positioning mechanisms 1 due to the offset of the second mounting bracket 5.

[0020] In this embodiment, the driving mechanism includes a drive motor 7, a fixing plate 8 is provided between the two sets of first mounting brackets 2, the drive motor 7 is provided at the left end of the fixing plate 8, and a mounting block 9 is provided on the right side of the opposite end of the two sets of fixing blocks 6. A connecting screw 10 is rotatably provided at the left end of the mounting block 9, and the left end of the connecting screw 10 passes through the fixing plate 8 and is connected to the right output end of the drive motor 7. A threaded cylinder 11 is threadedly connected to the outside of the connecting screw 10. A connecting plate 12 is provided between the two sets of second mounting brackets 5. The connecting plate 12 is provided with a reserved hole, and the inside of the reserved hole of the connecting plate 12 is connected to the outside of the threaded cylinder 11. A protective component is provided on the top of the fixing plate 8 and the top of the connecting plate 12. When adjusting the spacing of positioning mechanism 1, the drive motor 7 at the left end of the fixed plate 8 is started. The output end of the drive motor 7 on the right side drives the connecting screw 10 passing through the fixed plate 8 to rotate. The threaded cylinder 11 connected to the outer side of the connecting screw 10 moves axially with the screw as it rotates. The outer side of the threaded cylinder 11 is connected to the inner side of the reserved hole of the connecting plate 12, thereby driving the connecting plate 12 to move. The two ends of the connecting plate 12 are connected to two sets of second mounting brackets 5. The second mounting brackets 5 slide synchronously with the connecting plate 12, ultimately driving the second connecting seat 4 and the corresponding positioning mechanism 1 to move, thereby realizing the adjustment of the spacing between the two sets of positioning mechanisms 1.

[0021] In this embodiment, the protective component includes a baffle 13 and two sets of positioning screws 14. A first positioning rod 15 is provided on both the front and rear sides of the top of the fixing plate 8, and a second positioning rod 16 is provided on both the front and rear sides of the top of the connecting plate 12. A slot is provided at both the front and rear ends of the left side of the bottom of the baffle 13. The two sets of baffle 13 slots are respectively engaged with the corresponding set of first positioning rods 15. A sliding hole is provided on both the front and rear sides of the right side of the bottom of the baffle 13. A slider 17 is slidably disposed within the sliding holes of both sets of baffle 13. The bottom of each slider 17 is respectively attached to the top of the corresponding set of second positioning rods 16. Threaded holes are provided through each slider 17 and the corresponding second positioning rod 16. The outer sides of the two sets of positioning screws 14 are threadedly connected to the slider 17 and the second positioning rod 16 through the threaded holes. When the drive mechanism moves the connecting plate 12, the second positioning rod 16 on the top of the connecting plate 12 moves synchronously with the connecting plate 12. The slider 17, which is attached to the top of the second positioning rod 16, slides along the sliding hole at the bottom right end of the baffle 13. The bottom left side of the baffle 13 is fixed to the first positioning rod 15 on the top of the fixing plate 8 through a slot. The slider 17 and the second positioning rod 16 are connected through a through threaded hole. When the spacing of the positioning mechanism 1 is adjusted to the correct position, the rotating disk 21 on the top of the positioning screw 14 is rotated, which drives the positioning screw 14 to tighten through the threaded hole, so that the slider 17 and the second positioning rod 16 are tightly fixed, thereby locking the relative position of the baffle 13 and the connecting plate 12. When adjusting the spacing, the positioning screw 14 is rotated in the opposite direction to release the lock, and the slider 17 can then move with the second positioning rod 16. The baffle 13 always covers the top of the drive mechanism, preventing dust and debris from entering the drive components.

[0022] In summary, during adjustment, the drive motor 7 at the left end of the fixed plate 8 is started, and its output end drives the connecting screw 10 to rotate. The threaded cylinder 11 on the outside of the connecting screw 10 moves with the rotation of the connecting screw 10, which drives the connecting plate 12 and the two sets of second mounting brackets 5 to move synchronously. The guide blocks 18 at the upper and lower ends of the inner side of the second mounting bracket 5 slide along the sliding grooves at the top and bottom of the fixed block 6.

[0023] The top of the second mounting bracket 5 is connected to the bottom of the second connecting seat 4. The second connecting seat 4 drives the corresponding set of positioning mechanisms 1 to move. The other set of positioning mechanisms 1 is fixed to the first mounting bracket 2 through the first connecting seat 3. The distance between the two sets of positioning mechanisms 1 is adjusted as they move. At the same time, the second positioning rod 16 at the top of the connecting plate 12 drives the slider 17 to slide along the sliding hole of the baffle 13.

[0024] During uncoiling, the anti-slip pads 22 at the bottom of the four sets of support seats 19 stabilize the device, the rolling wheels 20 at the bottom of the second mounting frame 5 assist in sliding, and the two sets of positioning mechanisms 1 limit the steel strip to complete the uncoiling positioning.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
