Description

Technical Field

[0001] The utility model relates to the technical field of coil material processing and treatment, in particular to a material leading and bending device and a coil material processing system. Background Art

[0002] To facilitate material transportation and storage, metal materials (such as steel or aluminum) are processed into coils. Before processing, these coils are typically unwound by an unwinding device and flattened by a leveling device to obtain flat sheets for subsequent processing. When processing these coils, a multi-roller leveling and pressurization method is typically used first to induce alternating bending deformation to eliminate the unevenness of the original curvature, followed by gradual leveling. Before the sheet enters the leveler, the coil needs to be unwound. During the unwinding process, the coil experiences significant stress due to its inherent curvature, making feeding difficult.

[0003] Chinese patent CN202322700119.7 discloses a material head bending device, which is installed on a support base between an uncoiler and a leveler; a material pressing arm rotatably connected to the support base via a rotating shaft; and a shovel mechanism installed below the material pressing arm. The utility model designs a material pressing arm consisting of a front arm, a rear arm, and a roller. The roller contacts the lead end of the sheet coil. During the uncoiling process, the material pressing arm always presses the sheet to prevent the sheet coil from unraveling. After the sheet coil is uncoiled, the second oil cylinder extends to allow the folding plate to extend and receive the sheet. At the same time, the first oil cylinder extends to push the folding seat upward to provide a bending force on the sheet, offsetting the bending force generated by the sheet rewinding. This overcomes the problem of the sheet's inherent bending during the uncoiling process making it difficult to smoothly enter the leveler. The pressure of the material pressing arm and the bending of the shovel mechanism ensure smooth feeding of the leveler. This solution only bends the incoming sheet once, which is insufficient to offset the bending force of the rewinding.

[0004] The utility model overcomes the shortcomings of the prior art and provides a material guiding and bending device and a coil material processing system, which can perform secondary bending on the coiled material sheet and offset more winding bending force. Utility Model Content

[0037] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Coiled materials refer to sheets that are rolled into coils for easy transportation and storage, specifically steel coils, aluminum coils, etc.

[0039] like Figure 1-6 The figure shows an embodiment of the material guiding and bending device provided by the present invention.

[0040] Please refer to Figure 1-6 This embodiment is used for guiding the coil material head and bending the plate.

[0041] This embodiment includes a first frame 110, a pressing arm 130 hinged to the first frame 110 is provided on the upper side of the first frame 110, a first bending assembly 130 and a second bending assembly 140 are provided on the lower side of the first frame 110, and a guiding assembly 150 is provided between the first bending assembly 130 and the second bending assembly 140.

[0042] The first end of the pressing arm 120 is provided with a first roller 121, which is used to contact the coil. The pressing arm 120 and the first roller 121 are used to press the coil in the unwinding assembly 200 to prevent the coil from spreading.

[0043] The unwinding assembly 200 rotates and drives the coil into the first bending assembly 100. The first bending assembly 130 is used to pull the coil head and perform the first bend on the received sheet. The unwinding assembly 200 drives the bent sheet through the guide assembly 150, which conveys the sheet to the second bending assembly 140, which performs the second bend on the sheet. The sheet accumulates bending stress when it is rolled into a coil. Before it is unwound by the unwinding assembly 200 and moved to the flattening device, it still has a large amount of bending stress, which is not conducive to feeding the sheet into the flattening device. In this embodiment, the unwound sheet is bent multiple times in the opposite direction of the coil to offset the bending stress and facilitate subsequent feeding of the sheet into the flattening device.

[0044] In one embodiment, the first bending assembly 130 includes a receiving platform 131, the rear end of which is hinged to the first frame 110, and the front end of which is tapered. A first cylinder 132 is provided below the receiving platform 131, and the first cylinder 132 is provided on the first frame 110. The telescopic end of the first cylinder 132 is hinged to the receiving platform 131, thereby driving the receiving platform 131 to rotate. The receiving platform 131 is provided with a guide plate 133 and a second cylinder 134. The second cylinder 134 is connected to the rear end of the guide plate 133, pushing the guide plate 133 out from the middle of the tapered front end of the receiving platform 131. The front end of the guide plate 133 is provided with a second roller 135, which is used to reduce friction when the plate moves.

[0045] The guide plate 133 is a long, rectangular strip. A second pneumatic cylinder 134 propels the guide plate 133 out from the top of the receiving platform 131 to receive the coil head from the unwinding assembly 200. Driven by the unwinding assembly 200, the coil head moves along the guide plate 133 to the receiving platform. The first cylinder 132 propels the receiving platform 131 upward, bending the sheet material received by the receiving platform 131 upward—the first bend. The guide plate 133 is retractable to accommodate coils of varying diameters. The tapered design of the receiving platform 131 minimizes contact between the front end of the receiving platform and the cylindrical surface of the coil.

[0046] In one embodiment, the press arm 120 is L-shaped. Its rear end is hinged to the first frame 110, and its front end is equipped with a first roller 121 and a detection wheel 122. The press arm 120 is equipped with a first power member 123, which drives the first roller 121 to rotate. The first frame 110 is equipped with a third cylinder 124, which drives the press arm 120 to rotate about the hinge point.

[0047] The press arm 120 is used to compress the coil in the unwinding assembly 200 to prevent it from unraveling. The press arm 120 is raised or lowered by a third cylinder 124. The first power element 123, which can be a motor, rotates the first roller 121, which is used to tighten the coil.

[0048] In one embodiment, the feed guide assembly 150 includes a lower feed guide roller 151 and an upper feed guide roller 152, with the upper feed guide roller 152 positioned above the lower feed guide roller 151. The upper feed guide roller 152 is moved toward or away from the lower feed guide roller 151 by a fourth cylinder 153. The lower feed guide roller 151 is connected to a second power member 154, which can be a motor. Both ends of the upper feed guide roller 152 engage with a rack located on the first frame 100 via gears, ensuring that the upper feed guide roller 152 maintains overall movement when moved by the fourth cylinder 153.

[0049] The fourth air cylinder 153 drives the upper feed roller 152 to move upward away from the lower feed roller 151. When the unwinding assembly 200 drives the sheet to pass between the upper feed roller 152 and the lower feed roller 151, the fourth air cylinder 153 drives the upper feed roller 152 to move downward toward the lower feed roller 151, making contact with the upper side of the sheet. The lower feed roller 151 then makes contact with the lower side of the sheet, and the lower feed roller 151 rotates to feed the sheet.

[0050] In one embodiment, if Figure 5 As shown, the second bending assembly 140 includes a fifth cylinder 141, a load-bearing roller 142, and a load-bearing platform 143. The load-bearing roller 142 and the load-bearing platform are connected at both ends by a connecting plate 145. The connecting plate 145 is hinged to both ends of the lower feed roller 151. The load-bearing roller 142 is positioned adjacent to the lower feed roller 151 and the load-bearing platform 143, respectively, and is located between the lower feed roller 151 and the load-bearing platform 143. The roller surfaces of the load-bearing roller 142 and the lower feed roller 151 are each provided with a mutually aligned gap, within which a load-bearing bar 144 is positioned. The load-bearing bar 144 extends from the underside of the lower feed roller 151 to the upper side of the load-bearing roller 142 and further to the surface of the load-bearing platform 143, where it is fixedly connected to the upper surface of the load-bearing platform 143. The fifth cylinder 141 is provided on the first frame 110 , and the telescopic end of the fifth cylinder 141 is hinged to the carrying platform 143 , pushing the carrying platform 143 and the carrying roller 142 to rotate around the lower guide roller 143 .

[0051] The fifth cylinder 141 lifts the support platform 142 and rotates it about its hinge point, causing the support bar 144 connected to the support platform 142 to form a predetermined angle, thereby bending the sheet material supported on the upper side of the support bar 144 upward for a second time. The support bar 144 extends from the lower side of the lower guide roller 151 to the upper side of the support roller 142 and further to the surface of the support platform 143. This design prevents the sheet material from getting stuck in the gap between the support roller 142 and the lower guide roller 151 during movement.

[0052] In one embodiment, a limit plate 160 is provided above the outlet of the second bending assembly 140, and the plate surface of the limit plate 160 faces the direction in which the second bending assembly 140 bends the plate. The height of the limit plate 160 is adjusted by the sixth cylinder 161, and the sixth cylinder 161 is provided on the first frame 110. The plate contacts the limit plate 160 for the third bending.

[0053] The sheet material is bent upward by the second bending assembly 140. The stop plate 160 prevents the sheet material from further upward movement. Simultaneously, the stop plate 160 causes the sheet material to bend downward, thereby offsetting some of the bending stress generated by the first two upward bends. Furthermore, a lower baffle 162 is provided below the outlet of the second bending assembly 140. This lower baffle 162 is arranged parallel to the stop plate 160, forming a conveying channel for the sheet material.

[0054] In one embodiment, if Figure 1 and Figure 6 As shown, the unwinding assembly 200 includes a second frame 210 and a seventh cylinder 220. The second frame 210 is equipped with an expansion roller 230, a limiting roller 240, and a third power member 250. The third power member 250 and the seventh cylinder 220 are located on the second frame 210. The seventh cylinder 220 drives the expansion roller 230 to expand and contract, while the third power member 250 rotates the expansion roller 230. The third power member 250 can be a motor. The limiting roller 240 is located on the second frame 210 and is used to limit the end surface of the coil.

[0055] The expansion roller 230 passes through the coil's opening and expands to contact the wall of the opening, securing the coil. Rotation of the expansion roller 230 drives the coil's rotation. The expansion roller 230 employs a common unwinding mechanism structure and will not be described in detail. The limiting roller 240 limits the coil's end face and maintains axial positioning on the expansion roller 230.

[0056] In one embodiment, the limiting roller 240 is connected to the support frame 211 of the second frame 210 via a limiting telescopic shaft 241. The second frame 210 is equipped with an eighth cylinder 242, which propels the limiting roller 240 along the limiting telescopic shaft 241. The limiting telescopic shaft 241 is arranged parallel to the expansion and contraction roller 230. The limiting roller 240 is arranged in the radial direction of the web.

[0057] Specifically, there are multiple limiting rollers 240, connected by a connecting plate 243. In this embodiment, there are two limiting rollers 240, located above the expansion and contraction rollers 230. The limiting rollers 240 are arranged in the radial direction of the web, and the two limiting rollers 240 are symmetrically arranged. The telescopic end of the eighth cylinder 242 is connected to the connecting plate 243. A rack 244 is provided on the surface of the limiting telescopic shaft 241. The support frame 211 of the second frame is equipped with a gear 245, which meshes with the rack 244. The rack and gear achieve synchronous extension and contraction of the limiting telescopic shaft 241 connected to each of the two limiting rollers 240.

[0058] like Figure 7-8 As shown, the present invention also provides an embodiment of a coil material processing system.

[0059] Please refer to Figure 7-8 This embodiment includes the above-mentioned material guiding and bending device 100, and also includes a coil moving device 300, a material discharging correction device 400 and a leveling device 500.

[0060] A conveyor track 700 is provided between the coil moving device 300 and the uncoiling assembly 200. The coil moving device 100 is used to secure and move the coil. The material guiding and bending device 100 is used to guide and bend the coil, bending the sheet material multiple times. The flattening device 500 is connected to the material guiding and bending device 100 and is used to flatten the sheet material. The discharge correction device 500 is connected to the flattening device 500 and is used to correct the feed material deviation.

[0061] The coil moving device 100 loads the coil and moves it along the conveyor track 700 to the uncoiling assembly 200. The coil guiding and bending device 100 guides the coil, bends the coiled material, and then conveys it to the leveling device 500. The leveling device 500 flattens the coiled material and conveys it via a conveyor belt to the discharge deflection correction device 400. The discharge deflection correction device 400 corrects the deflection of the coiled material during discharge.

[0062] A material pit 600 is provided between the discharging deviation-correcting device 400 and the leveling device 500 , and the material pit 600 is used to buffer the plates.
