Abstract
Description
Technical Field
[0001] The present invention relates to the field of metal coil processing, and more particularly to a metal coil uncoiler. Background Art
[0002] In the sheet metal processing industry, large-scale roller presses are commonly used to continuously press and form metal sheets. To facilitate production, improve efficiency, and reduce labor intensity, the raw sheet metal is pre-wound into cylindrical steel coils and stored on dedicated loading racks to maintain proper control. An uncoiler is a device that continuously or intermittently unwinds a cylindrical steel coil. Currently, there are many types of uncoilers, including mechanical passive uncoilers, semi-automatic uncoilers, and fully automatic uncoilers. Due to structural limitations, uncoilers can only expand steel strips with smaller pore sizes. However, the pore sizes of coils vary greatly. When winding coils with larger pore sizes, the coils are not securely fixed during use, and may wobble or even fall off, disrupting normal production. Therefore, existing uncoilers require inserting wood or other objects into the expansion rack to expand coils with larger inner diameters. However, this simple method is unsafe, and the wood often falls off, resulting in significant steel strip loss and affecting production efficiency.
[0003] In response to this technical problem, a Chinese patent with authorization announcement number (application number) 202020907688.2 discloses a metal coil uncoiler. The utility model relates to the field of metal coil processing technology, specifically to a metal coil uncoiler, including an uncoiler main body, a turntable is provided at the power shaft end of the uncoiler main body, a rotating roller is provided at the front middle part of the turntable, and four groups of rectangular grooves are provided on the side walls around the rotating roller. The utility model provides a metal coil uncoiler. Through the design and use of a series of structures, the utility model avoids the use of a hydraulic cylinder to drive the adjustment method during use. This results in high maintenance costs and a high degree of specialization required for maintenance, which reduces its practicality. On the other hand, when the metal coil is fixed by adjusting the four sets of arc plates, the positioning and fixation can be performed quickly and accurately, avoiding damage to the metal coil if the fixing force is too large, and poor fixing effect if the fixing force is too small. However, when the metal coil uncoiler is loading the steel coil, if a lifting placement table is used for auxiliary loading, the steel coil is of too high quality and contact with the placement table will cause collision and friction, which will accelerate the wear of the placement table after long-term use and reduce its service life.
[0004] Therefore, a metal coil uncoiler is proposed. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0034] Example 1:
[0035] See also Figures 1 to 3 A metal coil uncoiler includes a uncoiler main body 1, a sliding guide rail 101 is provided on the front end surface of the uncoiler main body 1, and a driving vehicle 2 is routtably installed on the upper surface of the sliding guide rail 101, a servo controller 201 is installed on one side surface of the driving vehicle 2, and a hydraulic lift 202 is installed on the upper surface of the driving vehicle 2. This technical solution, the arrangement of the connecting plate 208, the bidirectional spiral drive rod and the sliding seat, and the arrangement of the placement seat 203 can be used with the assistance of the hydraulic lift 202 and the driving vehicle 2 to accurately install the metal coil on the outer surface of the rotating disk 4 of the uncoiler main body 1, thereby improving the efficiency and accuracy of the installation.

This technical solution, through the setting of the rotating roller 205, can reduce the friction of the steel coil on the placement seat 203 by rolling friction with the outer surface of the steel coil when the steel coil is transported using the placement seat 203, thereby avoiding damage to the placement seat 203.
[0037] A guide groove 206 is provided in the middle of the upper surface of the placement seat 203, and a connecting plate 207 is installed on the lower surface of the guide groove 206, and a bidirectional spiral drive rod 208 is rotatably installed on the inner surface of the connecting plate 207. This technical solution, through the setting of the bidirectional spiral drive rod 208, can drive the sliding seat 209 to slide along the guide groove 206 according to the size of the steel coil, so that the friction plate 302 can position the outer surface of the steel coil so that it can accurately contact the outer surface of the steel coil, thereby improving the stability of the steel coil during transportation.
[0038] A sliding seat 209 is spirally installed on the outer surface of the bidirectional spiral drive rod 208, and a sliding connection is set between the sliding seat 209 and the guide groove 206. This technical solution, through the setting of the sliding seat 209, can drive the friction plate 302 to slide along the guide groove 206 and adjust the position of the friction plate 302.
[0039] Figure 4As shown, an electric lifting rod 3 is installed on the upper surface of the sliding seat 209, and a limiting slide bar 301 is slidably installed on the upper surface of the electric lifting rod 3, and a friction plate 302 is provided on the upper surface of the limiting slide bar 301.

This technical solution can drive the arc plate 403 to diffuse outward through the setting of the driving connecting rod 402, so that the contact plate 404 with the friction plate 2 405 can contact the inner surface of the steel coil, so that it can be fitted and fixed with the inner surface of the steel coil, thereby avoiding it from loosening when the rotating disk 4 rotates, affecting the uncoiler effect.
[0042] A limiting slide bar 2 406 is slidably installed on the outer surface of the arc-shaped plate 403, and a compression spring 407 is provided on the outer surface of the lower end of the limiting slide bar 2 406, and a contact plate 404 is provided on the upper surface of the limiting slide bar 2 406, and a friction plate 2 405 is provided on the upper surface of the contact plate 404. This technical solution, through the setting of the compression spring 407, can drive the friction plate 2 405 to fit with the steel coil with an irregular inner circle through compression and reset, thereby improving the fitting rate of the friction plate 2 405 and reducing the gap between the friction plate 2 405 and the inner surface of the steel coil.
[0043] Figures 8 and 9 As shown, a sliding frame 5 is provided on the left surface of the uncoiler body 1, and a support plate 501 is slidably installed on the outer surface of the sliding frame 5, and a sliding plate 502 is provided on the upper surface of the support plate 501. This technical solution, through the setting of the sliding frame 5, can control the support plate 501 to slide and adjust by sliding, so as to facilitate the leveling of the steel coil after uncoiled.
[0044] The outer surface of the support plate 501 is provided with a pneumatic lifting rod 507, and the output end of the pneumatic lifting rod 507 is connected with the outer surface of the sliding plate 502, through the setting of the pneumatic lifting rod 507, the sliding plate 502 can be driven to slide upwards to pull the uncoiled steel coil, so as to avoid loosening.
[0045] The surface of the sliding plate 502 is provided with a limiting sliding groove 503, and the bottom surface of the limiting sliding groove 503 is rotatably installed with a threaded drive rod 504, the lower end outer surface of the threaded drive rod 504 is spirally installed with a lower pressing roller 505, and the upper end outer surface of the threaded drive rod 504 is rotatably installed with an upper pressing roller 506, through the setting of the threaded drive rod 504, the lower pressing roller 505 can be driven to slide upwards along the limiting sliding groove 503 in a spiral transmission mode, the distance between the lower pressing roller 505 and the upper pressing roller 506 is controlled according to the thickness of the steel coil, so as to flatten the steel coil, and the uncoiling effect is improved.
[0046] Method for use: when the steel coil uncoiling operation is carried out, first, the steel coil is stably placed on the placing seat 203. At this time, the rotating roller 205 on the placing seat 203 will first contact the outer surface of the steel coil, and through the rolling rotation mode, the friction between the steel coil and the rotating roller 205 is significantly reduced, which lays a good foundation for subsequent installation operation. After the initial placement is completed, according to the actual size of the steel coil, the bidirectional spiral drive rod 208 is started to drive the sliding seat 209 to slide accurately along the guide sliding groove 206, and then the position of the friction plate one 302 is accurately adjusted.
[0047] After the position adjustment is completed, the electric lifting rod 3 is started synchronously, so that the friction plate one 302 slowly rises and closely contacts the outer surface of the steel coil, so as to firmly fix the steel coil, and effectively prevent the steel coil from shaking during the uncoiling process. It is worth noting that during the rising process of the electric lifting rod 3, if the rising height exceeds the bearing threshold of the pressure relief spring 305, the pressure relief spring 305 will be deformed due to compression, driving the friction plate one 302 to slide downwardly along the limiting sliding rod one 301, through this ingenious design, overload protection is provided for the electric lifting rod 3, avoiding damage to the equipment.
[0048] After the outer surface of the steel coil is fixed, the driving trolley 2 and the hydraulic elevator 202 are cooperated and operated by the servo controller 201, so as to realize the accurate movement of the steel coil, and assist to complete the installation and connection of the steel coil and the rotating disc 4 of the uncoiler. When the steel coil is accurately moved to the middle position of the rotating disc 4, the servo motor 401 is started to drive the driving connecting rod 402 to move, driving the arc-shaped plate 403 to stably spread outward until the contact plate 404 with the friction plate two 405 closely contacts the inner surface of the steel coil. At this time, the compression spring 407 relies on the elastic reset characteristic to make the friction plate two 405 fully contact the irregular inner circle of the steel coil, and the stable installation and fixation of the steel coil are completed. After the fixation process is completed, the driving trolley 2 is reset, and the steel coil uncoiling process can be started.
[0049] During the uncoiling process, the unrolled coil is first conveyed to a designated position on the outer surface of the lower pressure roller 505. To prevent wrinkles on the coil surface during uncoiling, the threaded drive rod 504 is activated, driving the lower pressure roller 505 to slide precisely upward along the limiting chute 503, depending on the thickness of the coil. The spacing between the lower pressure roller 505 and the upper pressure roller 506 is flexibly adjusted to ensure a perfect fit between the upper and lower pressure rollers and the coil surface. Finally, the pneumatic lift rod 507 is activated, driving the sliding plate 502 to slide smoothly off the upper surface of the support plate 501. During this process, the coil is straightened, creating ideal conditions for smooth uncoiling. At this point, the uncoiling operation officially begins.
[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
