Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip uncoiling production, specifically a telescopic device for guiding strip material smoothly into a slitting machine for slitting operations. Background Technology
[0002] In the non-ferrous metals processing industry, strip uncoiling is a crucial starting point for slitting. With the industry's rapid development, the market has placed increasingly stringent demands on the precision, production efficiency, and product quality of strip processing. In current production processes, the telescopic device plays a core role in guiding the strip during uncoiling, and its performance directly affects the smooth operation of production.
[0003] However, traditional telescopic devices have several problems. Firstly, due to limitations in their structural design and material selection, they are prone to jamming during long-term use. For example, some telescopic guide plate connecting components lack precision, easily leading to misalignment and jamming during frequent telescopic movements, preventing the guide plate from extending and retracting smoothly. This not only prolongs uncoiling time but may also cause deviations in the strip's position at the initial stage of uncoiling, affecting subsequent slitting accuracy. Secondly, the friction between the telescopic guide plate and the strip, as well as between the telescopic guide plate's own moving parts, is excessive. This is because traditional telescopic devices often use ordinary materials with high surface roughness, generating significant frictional resistance during contact with the strip and relative movement. Excessive friction not only hinders the smooth operation of the telescopic guide plate but also causes scratches on the strip's head and tail. These scratches reduce the strip's surface quality. For non-ferrous metal products with extremely high surface quality requirements, such as high-precision copper and aluminum strips, the presence of scratches can lead to direct product scrapping, severely impacting product quality and the company's economic benefits.
[0004] Furthermore, with the continuous expansion of large slitting machine production scale and the increase in production speed, traditional telescopic devices can no longer meet the growing production demands. Their poor stability and high failure rate necessitate frequent downtime for maintenance during production, further reducing production efficiency and increasing production costs. For these reasons, developing a new, efficient, and stable telescopic device is urgently needed. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a telescopic device for strip uncoiling production, which solves the problems of traditional telescopic guide plate devices such as jamming, high friction, and poor operation, thereby affecting production efficiency and product quality.
[0006] To achieve the above objectives, the specific solution adopted by this utility model is as follows:
[0007] A telescopic device for strip uncoiling production is provided on one side of the uncoiler, including a guide roller and two fixed plates installed at both ends of the guide roller. The extension direction of the fixed plates is perpendicular to the extension direction of the guide roller. A telescopic component is clamped between the two fixed plates. A support frame is connected to the bottom surface of the two fixed plates. A hydraulic cylinder is installed on the support frame. The hydraulic cylinder can drive the telescopic component to reciprocate and extend along the extension direction of the fixed plates, thereby transporting the strip from one end of the telescopic component to the guide roller, and then feeding it into the slitting machine for cutting.
[0008] Both the upper and lower surfaces of the two fixed plates are provided with auxiliary sliding plates, which are in contact with the telescopic assembly to reduce the friction force when the telescopic assembly moves.
[0009] Furthermore, the telescopic component has grooves at both ends that mate with the fixed plate.
[0010] Furthermore, the telescopic assembly includes a telescopic guide plate placed on two fixed plates, and a sliding plate located below the fixed plates and connected to the telescopic guide plate by guide bolts, with a groove formed between the telescopic guide plate and the sliding plate.
[0011] Furthermore, a positioning sleeve is fitted onto the guide bolt to ensure that the groove size matches the total thickness of the fixing plate and the sliding plate.
[0012] Furthermore, a rolling element is fitted on the outside of the positioning sleeve on the guide bolt, which can reduce the frictional resistance between the telescopic component and the fixed plate.
[0013] Furthermore, the end of the telescopic guide plate away from the guide roller is provided with a friction-reducing plate to reduce friction on the material head.
[0014] Furthermore, a first friction-resistant plate is installed on both sides of the telescopic guide plate, and the first friction-resistant plate is fixedly connected to the upper auxiliary slide plate.
[0015] Furthermore, the upper surface of the telescopic guide plate is provided with a second friction-resistant plate.
[0016] Beneficial effects:
[0017] (1) A complete strip transport and guiding system is formed by setting guide rollers, fixed plates, telescopic components, support frames and hydraulic cylinders. The hydraulic cylinder drives the telescopic components to reciprocate, so that the strip is transported from one end of the telescopic components to the guide rollers, and then sent to the slitting machine for cutting, ensuring the smooth progress of the strip uncoiling production process. The upper and lower surfaces of the fixed plate are equipped with sliding plates to reduce the friction of the telescopic components during movement, making the telescopic process smoother, improving the operating efficiency of the equipment, reducing the jamming caused by excessive friction, and thus improving production efficiency.
[0018] (2) Grooves are provided at both ends of the telescopic component to cooperate with the fixed plate, making the connection between the telescopic component and the fixed plate more stable. When the oil cylinder drives the telescopic component to extend and retract, it can better ensure the stability and accuracy of the telescopic component's movement, avoid deviation or shaking, help improve the accuracy of strip transportation, and ensure that the strip can be accurately transported to the guide roller, providing a stable foundation for subsequent slitting operations.
[0019] (3) The telescopic assembly consists of a telescopic guide plate and a sliding plate connected by guide bolts, with a groove formed between them. This structural design makes the structure of the telescopic assembly more reasonable and facilitates the realization of the telescopic function. The coordinated work of the telescopic guide plate and the sliding plate ensures the strength of the telescopic assembly while allowing for flexible telescopic movement to adapt to different production needs, further enhancing the stability and reliability of the strip material transportation process.
[0020] (4) A positioning sleeve is fitted on the guide bolt to ensure that the groove size matches the total thickness of the fixed plate and the sliding plate. This design ensures the connection accuracy between the telescopic component and the fixed plate, so that the telescopic component will not jam or shake due to inaccurate connection during movement, effectively improving the stability of equipment operation and the accuracy of strip transportation, which is conducive to improving product quality and reducing the defect rate caused by strip transportation deviation.
[0021] (5) Rolling elements are fitted on the guide bolts outside the positioning sleeve, which converts the sliding friction between the telescopic assembly and the fixed plate into rolling friction, greatly reducing frictional resistance. This not only makes the movement of the telescopic assembly smoother and reduces the energy consumption of the equipment, but also reduces wear between parts, extends the service life of the equipment, reduces maintenance costs, and improves the continuity and efficiency of production.
[0022] (6) A friction-reducing plate is installed at the end of the telescopic guide plate away from the guide roller. When the material head enters the telescopic guide plate, the friction-reducing plate can effectively reduce the friction between the material head and the telescopic guide plate, avoid scratches on the material head, thereby improving the surface quality of the strip, reducing product scrap due to material head damage, and improving the product qualification rate and the economic benefits of the enterprise.
[0023] (7) The first friction-resistant plate is installed on both sides of the telescopic guide plate and is fixedly connected to the upper sliding plate. The upper surface is provided with a second friction-resistant plate. The setting of the friction-resistant plate further reduces the friction between the strip and the telescopic guide plate, protects the surface of the strip in all directions, and reduces the risk of the strip being scratched during transportation. It is crucial for the production of high-precision non-ferrous metal strip products, and can significantly improve product quality and enhance the competitiveness of the company's products in the market.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.
[0030] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0031] This utility model discloses a telescopic device for strip uncoiling production. The device is located between the uncoiler and the slitting machine. Referring to Figures 1 to 3, it specifically includes a guide roller 10 and two fixed plates 4 mounted at both ends of the guide roller 10. The extension direction of the fixed plates 4 is perpendicular to the extension direction of the guide roller 10. A telescopic component is clamped between the two fixed plates 4. A support frame 14 is connected to the bottom surface of the two fixed plates 4, and a hydraulic cylinder 1 is mounted on the support frame 14. The hydraulic cylinder 1 can drive the telescopic component to reciprocate and extend along the extension direction of the fixed plates 4. With this design, the strip can be transported from one end of the telescopic component to the guide roller 10, and then fed into the slitting machine by the guide roller 10 for slitting.
[0032] To reduce friction during the movement of the telescopic components, auxiliary sliding plates are provided on both the upper and lower surfaces of the two fixed plates 4, and these auxiliary sliding plates are in contact with the telescopic components. Specifically, the upper auxiliary sliding plate 3 is fastened to the fixed plate 4 with countersunk screws, and the lower auxiliary sliding plate 5 is fixed to the sliding plate 6 with set screws.
[0033] The telescopic assembly has grooves at both ends that cooperate with the fixed plate 4. Specifically, the telescopic assembly includes a telescopic guide plate 2 placed on two fixed plates 4 and a sliding plate 6 located below the fixed plate 4 and connected to the telescopic guide plate 2 by guide bolts 7. A groove is formed between the telescopic guide plate 2 and the sliding plate 6.
[0034] A positioning sleeve 8 is fitted onto the guide bolt 7. Its function is to ensure that the groove size matches the total thickness of the fixed plate 4 and the sliding plate 3 and 5, thereby ensuring the connection accuracy and stability between the telescopic component and the fixed plate 4.
[0035] Furthermore, a rolling element 9 is fitted on the guide bolt 7 outside the positioning sleeve 8. The presence of the rolling element 9 can transform the friction between the telescopic component and the fixed plate 4 into rolling friction, thereby reducing the frictional resistance between the telescopic component and the fixed plate 4 and making the movement of the telescopic component smoother.
[0036] A friction-reducing plate 11 is provided at the end of the telescopic guide plate 2 away from the guide roller 10 to reduce friction when the material head enters. First friction-resistant plates 12 are installed on both sides of the telescopic guide plate 2 and are fixedly connected to the upper auxiliary slide plate 3. A second friction-resistant plate 13 is provided on the upper surface of the telescopic guide plate 2. The first friction-resistant plate 12 can be made of a single layer of Teflon or multiple layers of Teflon fastened with countersunk screws, as long as the upper surface of the first friction-resistant plate 12 is flush with the upper surface of the second friction-resistant plate 13. The second friction-resistant plate 13 is also made of Teflon to reduce scratches during strip transportation.
[0037] The upper sliding plate 3, the lower sliding plate 5, the rolling element 9, and the friction-reducing plate 11 are all made of wear-resistant bronze (such as tin bronze), which has good wear resistance and can effectively reduce friction damage between the components, thus extending the service life of the entire telescopic device.
[0038] This utility model discloses a telescopic device for strip uncoiling production, installed between the uncoiler and the slitting machine. During operation, the uncoiler starts, and the cylinder head of the hydraulic cylinder 1 connects to the fixed hinge at the bottom of the telescopic guide plate 2, causing the telescopic guide plate 2 to extend. Under the rotational pressure of the uncoiling pressure roller, the strip material head is fed to the friction-reducing plate 11 at the end of the telescopic guide plate 2. The friction-reducing plate 11 effectively reduces friction at the material head, preventing scratches. When the telescopic guide plate 2 moves in and out, the rolling element 9 generates rolling friction with the fixed plate 4, and relative friction occurs between the telescopic guide plate 2 and the sliding plates 3 and 5, significantly reducing frictional resistance and ensuring smooth and stable movement of the telescopic guide plate 2. After the strip enters the tail of the telescopic guide plate 2, it is fed into the slitting machine by the guide roller 10. Throughout the process, the first and second Teflon friction-resistant plates 12 and 13 play a role in further reducing scratches on the strip. This utility model has a simple structure and strong applicability. It adopts a new telescopic device on the side of the uncoiler, which improves the relative movement and friction mode of the telescopic device, making the telescopic device flexible and stable in movement. At the same time, it reduces the scratches between the telescopic device and the surface of the strip, which is conducive to the passage of the strip head and tail and is easy to promote.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model in any way. All equivalent modifications or alterations made based on the essence of this utility model should be covered within the protection scope of this utility model.
