Description

Technical Field

[0001] This invention relates to the field of sheet metal uncoiling technology, and more specifically to an uncoiling device for aluminum sheet metal production. Background Technology

[0002] Uncoiling machines are key equipment in the uncoiling process of aluminum sheets. In the aluminum processing industry, tension-type uncoiling machines are widely used. These machines are simple and quick to operate and facilitate the loading and unloading of aluminum coils. However, during the uncoiling process, the sheet itself is bent and has great stress. In order to facilitate subsequent processing, the uncoiling part of the sheet needs to be leveled.

[0003] Chinese Patent CN220804993U discloses a material feeding and bending device, including a support base installed between an uncoiler and a leveler, a pressure arm rotatably connected to the support base via a rotating shaft, and a material shovel mechanism installed below the pressure arm. This patent designs a pressure arm composed of a front arm, a rear arm, and rollers. The rollers contact the lead-out end of the sheet metal roll. During the uncoiling process, the pressure arm constantly presses down on the sheet metal to prevent it from unwinding. After the sheet metal roll is uncoiled, a second hydraulic cylinder extends to allow a bending plate to extend and catch the sheet metal. Simultaneously, a first hydraulic cylinder extends to push the bending seat upwards, providing bending force to the sheet metal and counteracting the bending force generated by the sheet metal rewinding. This overcomes the problem of the sheet metal being difficult to smoothly enter the leveler during the uncoiling process due to its own bending. The pressure of the pressure arm and the bending of the material shovel mechanism ensure smooth material feeding into the leveler.

[0004] In practical implementation, the aforementioned patent requires a significant weight from the pressure arm. Since the pressure arm must remain constantly pressed against the sheet roll to prevent it from unraveling, it can rotate freely relative to the support. Therefore, when feeding the sheet roll, the position of the pressure arm must be manually adjusted according to its diameter to ensure the rollers press firmly against the roll – a very laborious process. Furthermore, as the sheet roll is unwound, the angle between the rollers and the folding plate constantly changes. To ensure smooth feeding, the position of the folding plate needs to be adjusted periodically, making the operation cumbersome.

[0005] Therefore, there is a need in the art for an uncoiling device for aluminum sheet production to solve the above problems. Summary of the Invention

[0006] This invention provides an uncoiling device for aluminum sheet production, aiming to solve the problem in related technologies that when leveling the uncoiling part of the sheet coil, a large amount of labor is required to adjust the leveling mechanism, and the operation process is cumbersome due to the need to constantly adjust the leveling mechanism during the leveling process.

[0007] An uncoiling device for aluminum sheet production according to the present invention includes a frame, a tensioning mechanism and a guiding mechanism disposed on the frame, wherein the guiding direction of the guiding mechanism is defined as from left to right. The guiding mechanism includes a guiding plate and a pressure roller one and a pressure roller two disposed at intervals along the left and right direction on the guiding plate. The guiding plate is provided with a driving member one for driving the pressure roller one to rotate and a driving member two for driving the pressure roller two to move along the left and right direction. The pressure roller one and the pressure roller two respectively form gaps with the guiding plate for the aluminum sheet to pass through. A push roller is provided between the first pressure roller and the second pressure roller. The guide plate has a clearance space for the push roller to move up and down. The frame is provided with a third driving component that drives the push roller to move up and down, so as to drive the push roller to move upward to bend the aluminum plate or to cooperate with the first pressure roller and the second pressure roller to clamp the aluminum plate.

[0008] The feeding mechanism of the uncoiling device for aluminum sheet production of the present invention does not interfere with the feeding of aluminum coils. Therefore, it is not necessary to spend a lot of labor adjusting the feeding mechanism when feeding aluminum coils. Moreover, during the uncoiling process, pressure roller one, pressure roller two, and push roller automatically cooperate to level the uncoiling section, eliminating the need for real-time adjustment of the feeding mechanism based on the uncoiling situation. The operation process is simple and quick. During the uncoiling process, the push roller bends the aluminum sheet in the opposite direction, which helps to level the uncoiled aluminum sheet and reduce springback. The control drive component two drives pressure roller two to reciprocate in the left and right direction, repeatedly crushing the uncoiled section to further improve the flatness of the aluminum sheet and improve the springback problem. In addition, pressure roller one, pressure roller two, and push roller of the present invention can cooperate to press the head of the aluminum coil, realizing the winding of loose coils and avoiding affecting the processing accuracy during subsequent uncoiling processing.

[0009] Preferably, the guide plate is provided with guide members at both ends of the second pressure roller to guide the second pressure roller to move gradually downward from left to right, and the guide members are elastically engaged with the guide plate in the vertical direction.

[0010] Preferably, mounting plates extend upward from the front and rear sides of the guide plate, the guide member is a guide rod, the upper surface of the guide rod is elastically connected to the corresponding mounting plate through an elastic telescopic rod, the lower surface of the guide rod is inclined downward from left to right, and a sliding groove is formed on the lower surface of the guide rod, a slider is slidably connected in the sliding groove, and the two ends of the pressure roller are respectively rotatably connected to the corresponding slider.

[0011] During the process of driving roller 2 to move to the right, roller 2 drives the slider to move along the groove at the bottom of the guide rod. The inclined lower surface of the guide rod guides roller 2 to move downward. However, due to the support of the aluminum plate and the guide plate, roller 2 cannot move downward. Therefore, as roller 2 moves to the right, it will gradually push the guide rod upward to squeeze elastic telescopic rod 1, thereby increasing the squeezing force of the guide rod on roller 2. This makes the pressure on the aluminum plate greater the more roller 2 moves to the right, further reducing the rebound of the aluminum plate.

[0012] Preferably, a conveyor belt is provided around the guide plate located below the second pressure roller. Conveyor rollers that drive the conveyor belt to rotate are respectively rotatably arranged at the left and right ends of the guide plate. The upper surface of the guide plate is flush with the top of the conveyor rollers. A second drive motor that drives the conveyor rollers to rotate is also provided on the guide plate.

[0013] The drive motor drives the conveyor roller to rotate, and the conveyor roller drives the conveyor belt to move synchronously with the unwound aluminum plate, reducing the wear of the aluminum plate.

[0014] Preferably, the front and rear ends of the pressure roller are respectively fixedly connected to coaxially arranged mounting disks, and the diameter of the mounting disks is larger than the diameter of the pressure roller.

[0015] The mounting plate can form stops on both the front and back sides of the uncoiled aluminum sheet to prevent the aluminum sheet from deviating from the guide plate and ensure that the aluminum sheet can be completely squeezed by the pressure roller.

[0016] Preferably, the second driving component includes a connecting rod, the left end of which is hinged to the eccentric part of the mounting plate, and the right end of which is hinged to the rotating shaft of the second pressure roller. When the first driving component drives the first pressure roller to rotate, the first pressure roller drives the mounting plate to rotate, and the mounting plate drives the second pressure roller to move back and forth left and right through the connecting rod.

[0017] The mounting plate drives the second pressure roller to move back and forth left and right via a connecting rod, eliminating the need to set up a separate drive source for the second pressure roller and reducing production costs.

[0018] Preferably, the connecting rod is a second elastic telescopic rod, the left end of which is hinged to the eccentric part of the mounting plate, and the right end of which is hinged to the rotating shaft of the second pressure roller.

[0019] Preferably, friction elements are evenly spaced along the outer periphery of the pressure roller.

[0020] Preferably, the friction element is a hollow rubber pad.

[0021] Preferably, the first driving component is a first driving motor, which is fixedly mounted on the corresponding guide plate. The first pressure roller is fixedly connected to the output end of the first driving motor. The third driving component is an electric push rod, which is fixedly mounted on the frame. The driving end of the electric push rod is fixedly connected to a U-shaped frame, and the top push roller is rotatably connected to the U-shaped frame.

[0022] The beneficial effects of the present invention are as follows: (1) The material guiding mechanism of the uncoiling device for aluminum sheet production of the present invention will not interfere with the placement of aluminum coil. Therefore, when placing aluminum coil, it is not necessary to spend a lot of labor to adjust the material guiding mechanism. Moreover, during the uncoiling process, the pressure roller one, pressure roller two and top push roller automatically cooperate to level the uncoiling part. There is no need to adjust the material guiding mechanism in real time according to the uncoiling situation. The operation process is simple and quick. (2) In the process of unwinding, the aluminum plate is bent in the opposite direction by the push roller, which helps to level the unwound aluminum plate and reduce the occurrence of springback. By controlling the second drive component to drive the second pressure roller to move back and forth in the left and right direction, the unwound part is repeatedly crushed, which further improves the flatness of the aluminum plate and improves the problem of aluminum plate springback. (3) In addition, the pressure roller one, pressure roller two and push roller of the present invention can work together to press the head of the aluminum coil, realize the winding of the loose coil, and avoid affecting the processing accuracy during subsequent unwinding.

[0030] 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.

[0031] 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.

[0032] The guiding direction of the material guiding mechanism is defined as from left to right. The guiding mechanism includes a guide plate 4 and pressure rollers 5 and 6 spaced apart along the left and right directions on the guide plate 4. The guide plate 4 is fixedly connected to the frame 1. The guide plate 4 is equipped with a first driving component for rotating the pressure roller 5 and a second driving component for moving the pressure roller 6 along the left and right directions. The pressure rollers 5 and 6 form gaps with the guide plate 4 to allow the aluminum plate to pass through. A push roller 7 is arranged between the pressure rollers 5 and 6. The guide plate 4 has clearance space for the push roller 7 to move up and down. The frame 1 is equipped with a third driving component for moving the push roller 7 up and down.

[0033] As an example, the first driving component is a drive motor 51, which is fixedly mounted on the corresponding guide plate 4, and the pressure roller 5 is connected to the output end of the drive motor 51. The third driving component is an electric push rod 71, which is fixedly mounted on the frame 1, and the drive end of the electric push rod 71 is fixedly connected to a U-shaped frame 72, and the push roller 7 is rotatably connected to the U-shaped frame 72.

[0034] After the aluminum coil is installed on the tensioning mechanism, the end of the aluminum coil is passed under the pressure roller 5. The drive motor 51 is controlled to drive the pressure roller 5 to rotate, passing the end of the coil under the pressure roller 6. Then the drive motor 51 is stopped, and the end of the coil is pressed onto the guide plate 4 by the pressure roller 5. The electric push rod 71 is controlled to drive the push roller 7 to move upward, so that the end of the aluminum coil is clamped between the pressure roller 5 and the push roller 7, and between the pressure roller 6 and the push roller 7, forming a tight and fixed end of the aluminum coil. Then the drive motor 3 is controlled to drive the rotating shaft 2 to rotate the aluminum coil in the winding direction, so that the aluminum coil changes from a loose state to a tight state, avoiding the loose aluminum coil from affecting the processing accuracy during subsequent unwinding.

[0035] After the aluminum coil is tightened, the drive motor 3 drives the rotating shaft 2 to unwind the aluminum coil. At the same time, the drive motor 51 drives the pressure roller 5 to rotate, conveying the aluminum sheet to the right. The linear speed of the pressure roller 5 is greater than the linear speed of the rotating shaft 2. During the rotation of the pressure roller 5, the pressure roller 5 always has a tendency to pull the aluminum sheet to the right, thus preventing the aluminum coil from loosening during unwinding. During the unwinding process, the push roller 7 bends the aluminum sheet in the opposite direction, which helps to level the unwound aluminum sheet and reduce the occurrence of springback. The drive motor 2 drives the pressure roller 6 to move back and forth in the left and right direction, repeatedly rolling the unwound part to further improve the flatness of the aluminum sheet and improve the problem of aluminum sheet springback.

[0036] The feeding mechanism of the uncoiling device for aluminum sheet production of the present invention does not interfere with the feeding of aluminum coils. Therefore, it is not necessary to spend a lot of labor adjusting the feeding mechanism when feeding aluminum coils. Moreover, during the uncoiling process, the pressure roller 5, pressure roller 6, and push roller 7 automatically cooperate to level the uncoiling section, eliminating the need for real-time adjustment of the feeding mechanism based on the uncoiling situation. The operation process is simple and quick. In addition, the pressure roller 5, pressure roller 6, and push roller 7 of the present invention can cooperate to press the head of the aluminum coil, realizing the winding of loose coils and avoiding affecting the processing accuracy during subsequent uncoiling processing.

[0037] The pressure roller 5 has friction elements evenly spaced along its outer circumference. As an example, the friction elements are hollow rubber pads 52. When the aluminum sheet passes under the pressure roller 5, the rubber pads 52 on the pressure roller 5 are compressed, increasing the friction between the pressure roller 5 and the aluminum sheet, making the aluminum coil less prone to loosening during unwinding. It is understood that in other embodiments, the friction elements may also be rubber protrusions evenly distributed on the pressure roller 5 to increase the friction between the pressure roller 5 and the aluminum sheet.

[0038] To further improve the leveling effect on the uncoiled aluminum sheet, in this embodiment, the guide plate 4 is provided with guide members at both ends of the pressure roller 6 to guide the pressure roller 6 to move gradually downward from left to right. The guide members are elastically engaged with the guide plate 4 vertically. Mounting plates 41 extend upward from both the front and rear sides of the guide plate 4. The guide members are guide rods 8. The upper surface of the guide rod 8 is elastically connected to the corresponding mounting plate 41 through an elastic telescopic rod 81. The lower surface of the guide rod 8 is inclined downward from left to right, and a groove 82 is opened on the lower surface of the guide rod 8. A slider 83 is slidably connected in the groove 82. Both ends of the pressure roller 6 are rotatably connected to the corresponding slider 83.

[0039] During the process of the second driving component driving the second pressure roller 6 to move to the right, the second pressure roller 6 drives the slider 83 to move along the groove 82 at the bottom of the guide rod 8. The inclined lower surface of the guide rod 8 guides the second pressure roller 6 to move downward. However, due to the support of the aluminum plate and the guide plate 4, the second pressure roller 6 cannot move downward. Therefore, as the second pressure roller 6 moves to the right, the second pressure roller 6 will gradually push the guide rod 8 upward to squeeze the elastic telescopic rod 81, thereby increasing the squeezing force of the guide rod 8 on the second pressure roller 6. This makes the pressure on the aluminum plate greater the more the second pressure roller 6 moves to the right, further reducing the rebound of the aluminum plate.

[0040] A conveyor belt 42 is provided around the guide plate 4 located below the pressure roller 6. Conveyor rollers 43, which drive the conveyor belt 42, are rotatably mounted on the left and right ends of the guide plate 4. The upper surface of the guide plate 4 is flush with the top of the conveyor rollers 43. A second drive motor (not shown in the figure) is also provided on the guide plate 4 to drive the conveyor rollers 43. The second drive motor drives the conveyor rollers 43 to rotate, causing the conveyor belt 42 to move synchronously with the unwound aluminum sheet, reducing wear on the aluminum sheet.

[0041] The front and rear ends of the pressure roller 5 are respectively fixedly connected to coaxially arranged mounting plates 9. The diameter of the mounting plates 9 is larger than the diameter of the pressure roller 5. The pressure roller 5 is fixedly connected to the output end of the drive motor 51 through the mounting plates 9. The mounting plates 9 can form stops on the front and rear sides of the uncoiled aluminum sheet to prevent the aluminum sheet from deviating from the guide plate 4 and ensure that the aluminum sheet can be completely squeezed by the pressure roller 5.

[0042] The second driving component includes a connecting rod, which is a second elastic telescopic rod 10. The mounting plate 9 includes a first plate 91 and a second plate 92 coaxially arranged. The left end of the second elastic telescopic rod 10 is hinged to the eccentric portion of the first plate 91 and the second plate 92, and the right end is hinged to the rotating shaft of the second pressure roller 6. The front and rear ends of the first pressure roller 5 are respectively fixedly connected to the first plate 91 of the corresponding mounting plate 9. The output end of the first driving motor 51 is fixedly connected to the second plate 92 of one of the mounting plates 9. When the first driving motor 51 drives the second plate 92 to rotate, the second plate 92 drives the first plate 91 and the first pressure roller 5 to rotate. The first plate 91 and the second plate 92 drive the second pressure roller 6 to reciprocate left and right through the connecting rod, eliminating the need for a separate driving source for the second pressure roller 6 and reducing production costs. It is understood that in other embodiments, the second driving component can also be a cylinder, which drives the second pressure roller 6 to reciprocate left and right.

[0043] As the diameter of the coil decreases, the tension of the coil itself increases, making it more prone to springback. Therefore, as the coil diameter decreases, the electric push rod 71 can be controlled to continue driving the push roller 7 upward, lifting the coil and increasing the protrusion height, thereby reducing the springback of the aluminum plate. As the push roller 7 continues to rise, the shortest distance between pressure roller 5 and pressure roller 6 increases. By setting the connecting rod as an elastic telescopic rod 10, the connecting rod can extend and retract according to the rise and fall of the push roller 7. This does not affect the driving of the pressure roller 6 by the connecting rod, and allows the pressure roller 6 to cooperate with the push roller 7 to bend the aluminum plate when it moves to the leftmost end.
