Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate uncoiling, in particular to an uncoiling device for aluminum plate production. BACKGROUND

[0002] The uncoiler is a key equipment in the aluminum plate uncoiling process. In the aluminum processing industry, the tension type uncoiler is widely used. This uncoiler is simple and fast to operate, and is convenient for taking and placing the aluminum coil. However, during the uncoiling process, the plate itself is bent and has a large stress. In order to facilitate subsequent processing, the uncoiled part of the plate needs to be flattened.

[0003] A material head material guiding and bending device is disclosed in Chinese Patent No. CN220804993U, which comprises a support seat installed between an uncoiler and a flattening machine, a pressing arm rotatably connected to the support seat through a rotating shaft, and a material shoveling mechanism installed below the pressing arm. The patent designs a pressing arm composed of a front arm, a rear arm and a roller. The roller is in contact with the leading end of the plate coil. During the uncoiling process of the material, the pressing arm always presses the plate to prevent the plate coil from spreading open. After the plate coil is uncoiled, the second oil cylinder extends to allow the material folding plate to extend and catch the plate. At the same time, the first oil cylinder extends to make the material folding seat pop up upward to provide bending force to the plate, which offsets the bending force generated by the plate winding and overcomes the problem that the plate is difficult to smoothly enter the flattening machine due to its own bending during the uncoiling process. The smooth feeding of the flattening machine is ensured by the pressing of the pressing arm and the bending of the material shoveling mechanism.

[0004] In the actual implementation process of the above-mentioned patent, since the pressing arm can always press on the plate coil to prevent the coil from spreading open, the weight of the pressing arm is usually relatively large, and the pressing arm can rotate freely relative to the support seat. Therefore, when the plate coil is placed, the position of the pressing arm needs to be manually adjusted according to the diameter of the plate coil, so that the roller on the pressing arm presses on the plate coil, which is undoubtedly very laborious. In addition, as the plate coil is continuously uncoiled, the angle between the roller and the material folding plate is also constantly changing. In order to ensure smooth feeding, the position of the material folding plate needs to be adjusted once after a period of time, which is a relatively cumbersome operation process.

[0005] Therefore, there is a need in the art for an uncoiling device for aluminum plate production to solve the above-mentioned problems. SUMMARY

[0006] The present application provides an uncoiling device for aluminum plate production, which aims to solve the problem in the related art that a large amount of labor is required to adjust the flattening mechanism when flattening the uncoiled part of the plate, and the flattening mechanism also needs to be constantly adjusted during the flattening process, resulting in a cumbersome operation process.

[0009] The material guiding mechanism of the unwinding device for aluminum plate production of the present application does not interfere with the placement of the aluminum coil, so it is not necessary to consume a lot of labor to adjust the material guiding mechanism when placing the aluminum coil, and during the unwinding process, the pressing roller one, the pressing roller two and the pushing roller automatically cooperate to flatten the unwound part, without the need to adjust the material guiding mechanism in real time according to the unwinding situation, and the operation process is simple and fast. The pushing roller bends the aluminum plate in the opposite direction during the unwinding process, which helps to flatten the unwound aluminum plate and reduces the occurrence of springback, and the driving part two drives the pressing roller two to reciprocate in the left-right direction, repeatedly rolling the unwound part, further improving the flatness of the aluminum plate and improving the springback problem of the aluminum plate.

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 6 As shown, an uncoiling device for aluminum sheet production according to the present invention includes a frame 1, a tensioning mechanism and a guiding mechanism disposed on the frame 1. The tensioning mechanism includes a rotating shaft 2, a sleeve 3 sleeved outside the rotating shaft 2, and four support plates 31 evenly distributed at intervals along the outer circumference of the sleeve 3. The axial direction of the rotating shaft 2 is defined as the front-to-back direction. The rotating shaft 2 is rotatably connected to the frame 1, and a drive motor (not shown in the figure) for driving the rotating shaft 2 is mounted on the frame 1. A positioning disk 21 is fixedly connected to the rotating shaft 2 and is coaxially arranged. The positioning disk 21 has a limiting groove 22 corresponding to the support plate 31, and the limiting groove 22 extends radially along the positioning disk 21. Each support plate 31 is slidably connected to the corresponding limiting groove 22, and rollers 32 located on the front and rear sides of the positioning disk 21 are rotatably connected to the support plate 31. Each support plate 31 is hinged to the sleeve 3 through a connecting rod 33. An electric push cylinder (not shown in the figure) is provided at the end of the rotating shaft 2 away from the drive motor 3, where the drive sleeve 3 moves axially along the rotating shaft 2. A limit block 23 is fixedly installed on the rotating shaft 2, and a sliding groove 34 that cooperates with the limit block 23 is provided on the sleeve 3. When the sleeve 3 moves toward the drive motor 3, it pushes the support plate 31 outward through the connecting rod 33 to fix the aluminum coil. When the sleeve 3 moves away from the drive motor 3, it drives the support plate 31 to retract inward through the connecting rod 33, thereby facilitating the removal of the aluminum coil.

[0036] The material guiding direction of the material guiding mechanism is defined as from left to right, and the material guiding mechanism comprises a material guiding plate 4, a pressing roller one 5 and a pressing roller two 6 which are arranged on the material guiding plate 4 in a left-right direction. The material guiding plate 4 is fixedly connected to the rack 1, and the material guiding plate 4 is provided with a driving part one for driving the pressing roller one 5 to rotate and a driving part two for driving the pressing roller two 6 to move in the left-right direction. The pressing roller one 5 and the pressing roller two 6 respectively form a gap for the aluminum plate to pass through between the pressing roller one 5 and the material guiding plate 4. A pushing roller 7 is arranged between the pressing roller one 5 and the pressing roller two 6, and the material guiding plate 4 is provided with a clearance space for the pushing roller 7 to move up and down, and the rack 1 is provided with a driving part three for driving the pushing roller 7 to move up and down.

[0037] As an example, the driving part one is a driving motor one 51 which is fixedly installed on the corresponding material guiding plate 4, and the pressing roller one 5 is connected with the output end of the driving motor one 51. The driving part three is an electric push rod 71 which is fixedly installed on the rack 1, and the driving end of the electric push rod 71 is fixedly connected with a U-shaped frame 72, and the pushing roller 7 is rotatably connected to the U-shaped frame 72.

[0038] After the aluminum coil material is installed on the tensioning mechanism, the material head of the aluminum coil material is arranged below the pressing roller one 5, the driving motor one 51 is controlled to drive the pressing roller one 5 to rotate, the material head is arranged below the pressing roller two 6, then the driving of the driving motor one 51 is stopped, the material head is pressed on the material guiding plate 4 by the pressing roller one 5, the electric push rod 71 is controlled to drive the pushing roller 7 to move upward, so that the material head of the aluminum coil material is clamped between the pressing roller one 5 and the pushing roller 7 and between the pressing roller two 6 and the pushing roller 7, the material head of the aluminum coil material is tightly fixed, then the driving motor three is controlled to drive the rotating shaft 2 to rotate the aluminum coil material in the direction of winding, so that the aluminum coil material changes from a loose state to a tight state, and the machining precision of the subsequent unwinding process is avoided to be affected by the loose aluminum coil material.

[0039] After the aluminum coil material is tightened, the driving motor three is controlled to drive the rotating shaft 2 to rotate the aluminum coil material to be unwound, and the driving motor one 51 is controlled to drive the pressing roller one 5 to rotate, so that the aluminum plate is conveyed to the right, and the linear speed of the pressing roller one 5 is greater than the linear speed of the rotating shaft 2. The pressing roller one 5 always has a tendency to pull the aluminum plate to the right in the process of rotating, so as to prevent the aluminum coil material from being loose in the process of unwinding. The pushing roller 7 bends the aluminum plate in the opposite direction in the process of unwinding, so as to help the unwound aluminum plate to be flattened and reduce the occurrence of springback. The driving part two is controlled to drive the pressing roller two 6 to reciprocatingly move in the left-right direction, so as to repeatedly roll the unwound part, further improve the flatness of the aluminum plate, and improve the problem of springback of the aluminum plate.

[0040] The material guiding mechanism of the unwinding device for aluminum plate production of the present application does not interfere with the placement of the aluminum coil, so there is no need to consume a lot of labor to adjust the material guiding mechanism when placing the aluminum coil, and during the unwinding process, the pressure roller one 5, the pressure roller two 6 and the push roller 7 automatically cooperate to flatten the unwound part, without the need to adjust the material guiding mechanism in real time according to the unwinding situation, the operation process is simple and fast. In addition, the pressure roller one 5, the pressure roller two 6 and the push roller 7 can cooperate to compress the material head of the aluminum coil, realize the winding of the loose coil, and avoid affecting the machining precision during the subsequent unwinding process.

[0041] The pressure roller one 5 is uniformly provided with friction pieces along its outer periphery, and as an example, the friction pieces are rubber pads 52 with a hollow structure. When the aluminum plate is arranged below the pressure roller one 5, the rubber pads 52 on the pressure roller one 5 are extruded, increasing the friction between the pressure roller one 5 and the aluminum plate, so that the aluminum coil is not easy to loosen during the unwinding process. It can be understood that in other embodiments, the friction pieces can also be rubber bumps, which are uniformly distributed on the pressure roller one 5 to increase the friction between the pressure roller one 5 and the aluminum plate.

[0042] To further improve the flattening effect of the unwound aluminum plate, in this embodiment, the guide plate 4 is provided with guide pieces at the front and rear ends of the pressure roller two 6, which gradually move downward from left to right. The guide pieces are elastically connected to the corresponding mounting plates 41 along the vertical direction. The guide pieces are guide rods 8, the upper surfaces of the guide rods 8 are elastically connected to the corresponding mounting plates 41 through elastic extension rods one 81, the lower surfaces of the guide rods 8 are inclined downward from left to right, and the lower surfaces of the guide rods 8 are provided with sliding grooves 82, the sliding grooves 82 are slidably connected with sliding blocks 83, and the two ends of the pressure roller two 6 are rotatably connected with the corresponding sliding blocks 83.

[0043] During the driving of the driving piece two to drive the pressure roller two 6 to move rightward, the pressure roller two 6 drives the sliding blocks 83 to move along the sliding grooves 82 at the bottom of the guide rods 8, and the inclined lower surfaces of the guide rods 8 guide the pressure roller two 6 to move downward, but due to the support of the aluminum plate and the guide plate 4, the pressure roller two 6 cannot move downward, so as the pressure roller two 6 moves rightward, the pressure roller two 6 gradually pushes the guide rods 8 upward to extrude the elastic extension rods one 81, thereby increasing the extrusion force of the guide rods 8 on the pressure roller two 6, so that the greater the rightward movement of the pressure roller two 6, the greater the pressure on the aluminum plate, further reducing the rebound of the aluminum plate.

[0044] The outer periphery of the guide plate 4 below the compression roller two 6 is provided with a conveying belt 42, the left and right ends of the guide plate 4 are respectively provided with a conveying roller 43 for driving the conveying belt 42 to rotate, and the upper surface of the guide plate 4 is flush with the top of the conveying roller 43, and the guide plate 4 is further provided with a driving motor two (not shown in the figure) for driving the conveying roller 43 to rotate. The conveying roller 43 drives the conveying belt 42 to move synchronously with the unwinding aluminum plate, reducing the wear of the aluminum plate.

[0045] The front and rear ends of the compression roller one 5 are respectively fixedly connected with coaxially arranged mounting discs 9, the diameter of the mounting disc 9 is larger than the diameter of the compression roller one 5, and the compression roller one 5 is fixedly connected with the output end of the driving motor one 51 through the mounting disc 9. The mounting disc 9 can form a stop on the front and rear sides of the unwound aluminum plate, avoiding the aluminum plate from being deflected out of the guide plate 4, and ensuring that the aluminum plate can pass through the extrusion of the compression roller one 5 completely.

[0046] The driving member two includes a connecting rod, which is an elastic telescopic rod two 10. The mounting disc 9 includes coaxially arranged disc one 91 and disc two 92, and the left end of the elastic telescopic rod two 10 is hinged to the eccentric positions of the disc one 91 and the disc two 92, and the right end is hinged to the rotating shaft of the compression roller two 6. The front and rear ends of the compression roller one 5 are respectively fixedly connected with the disc one 91 of the corresponding mounting disc 9, and the output end of the driving motor one 51 is fixedly connected with the disc two 92 of one of the mounting discs 9. When the driving motor one 51 drives the disc two 92 to rotate, the disc two 92 drives the disc one 91 and the compression roller one 5 to rotate, and the disc one 91 and the disc two 92 drive the compression roller two 6 to move left and right through the connecting rod, which saves the driving source for the compression roller two 6 and reduces the production cost. It can be understood that in other embodiments, the driving member two can also be a pneumatic cylinder, which drives the compression roller two 6 to move left and right.

[0047] As the diameter of the coiled material decreases, the tension of the coiled material itself becomes larger and larger, causing the coiled material to be more likely to rebound. Therefore, as the diameter of the coiled material becomes smaller and smaller, the electric push rod 71 can be controlled to continue driving the push roller 7 upward to lift the coiled material and increase the protrusion height, thereby reducing the rebound of the aluminum plate. When the push roller 7 continues to rise, the shortest distance between the compression roller one 5 and the compression roller two 6 will increase. By setting the connecting rod as an elastic telescopic rod two 10, the connecting rod can stretch and contract according to the rising and falling of the push roller 7, which does not affect the driving of the compression roller two 6 by the connecting rod, and also enables the compression roller two 6 to cooperate with the push roller 7 to bend the aluminum plate when the compression roller two 6 moves to the leftmost end.
