Abstract
Description
Technical Field
[0001] This application relates to the field of uncoiling technology for sleeve coils, and more particularly to an uncoiling device for sleeve coils of aluminum alloy cold rolling mills. Background Technology
[0002] Aluminum alloys are alloys with aluminum as the base and a certain amount of other alloying elements added. In the production and processing of aluminum alloys, it is necessary to process the aluminum alloys through a cold rolling mill. When processing aluminum alloys through a cold rolling mill, an uncoiling device is needed to uncoil and convey the aluminum alloy strip.
[0003] While existing unwinding devices can perform good unwinding operations on sleeve coils, the head of the coil is often bent during unwinding. Although the bent part can be initially leveled when the coil comes into contact with the conveyor roller, a certain degree of bending still exists at the head of the coil. It is necessary for the operator to lift and convey the bent part by hand using a material lifting rod. This is not very effective in leveling the bent head of the coil afterward, which reduces the efficiency of the coil being conveyed quickly from the conveyor roller. Furthermore, the synchronous traction conveying effect of the coil is not high, which reduces the efficiency of the unwinding device in unwinding and conveying the coil. Utility Model Content
[0004] This application provides an uncoiling device for aluminum alloy cold rolling mill sleeve coils to solve the problem mentioned in the background art that when the coil comes into contact with the conveyor roller, the curved part can be initially leveled, but the head of the coil still has a certain degree of curvature. The operator needs to lift and convey the curved part by hand using a material lifting rod. This results in poor leveling of the curved head of the coil and reduces the efficiency of rapid conveying of the coil from the conveyor roller.
[0005] This application provides an uncoiling device for aluminum alloy cold rolling mill sleeve coils, including a cold rolling mill body. An aluminum alloy strip is disposed on the outer wall of the cold rolling mill body. A guide plate located on one side of the aluminum alloy strip is rotatably connected to the outer wall of the cold rolling mill body. A conveying roller is rotatably connected to the outer wall of the cold rolling mill body. A sliding frame is slidably connected to the outer wall of the cold rolling mill body. A first telescopic rod is fixedly connected to the outer wall of the sliding frame. A first spring is sleeved on the outer wall of the first telescopic rod and fixedly connected to the outer wall of the sliding frame. A first servo motor is disposed on the outer wall of the sliding frame. A threaded rod is fixedly connected to the output end of the first servo motor. A traction pressure plate slidably connected to the outer wall of the sliding frame is threadedly connected to the outer wall of the threaded rod.
[0006] Preferably, a connecting frame is slidably connected to the outer wall of the cold rolling mill body, a second telescopic rod is fixedly connected to the outer wall of the connecting frame, a second spring is sleeved on the outer wall of the second telescopic rod and fixedly connected to the outer wall of the connecting frame, a second servo motor is provided on the outer wall of the connecting frame, a turntable is fixedly connected to the output end of the second servo motor, a pull rod is rotatably connected to the outer wall of the turntable, one end of the pull rod is rotatably connected to a pressure rod that is slidably connected to the outer wall of the connecting frame, and a lifting groove is provided at the connection between the outer wall of the connecting frame and the pressure rod.
[0007] Preferably, the other end of the first spring is fixedly connected to the outer wall of the cold rolling mill, and the first telescopic rod and the first spring are symmetrically arranged on both sides of the sliding frame.
[0008] Preferably, the threaded rod is provided in two sets, and the two sets of threaded rods rotate in opposite directions.
[0009] Preferably, the traction pressure plate forms a lifting structure with the sliding frame via a threaded rod, and the traction pressure plate is positioned on the movement trajectory of the conveying roller.
[0010] Preferably, the pull rod forms a rotating structure between the turntable and the pressure rod.
[0011] Preferably, the pressure rod forms a lifting structure with the lifting groove via a turntable and a pulling rod.
[0012] Beneficial effects:
[0013] While existing uncoiling devices can perform good uncoiling operations on sleeve coils, the head of the coil is often bent during uncoiling. Although the bent part can be initially leveled when the coil comes into contact with the conveyor roller, the head of the coil will still have a certain degree of curvature. It is necessary for the operator to lift and convey the bent part by hand using a material lifting rod. This is not very effective in leveling the bent head of the coil, reducing the efficiency of the coil being conveyed quickly from the conveyor roller, and also not very effective in synchronous traction conveying of the coil, thus reducing the efficiency of the uncoiling device in uncoiling and conveying the coil.
[0014] In use, when the guide plate and pressure bar work together to initially flatten the curved part of the coil head, the strip will pass through the conveyor rollers and be continuously conveyed on the cold rolling mill. At this time, the first servo motor can be turned on to drive the traction pressure plate to press and lift the curved part of the head through the rotation of the threaded rod. Under the continuous conveying of the strip, the sliding frame will slide along the outer wall of the cooler and squeeze the first telescopic rod and the first spring. After the strip head is flattened and conveyed again, the traction pressure plate is loosened. At this time, the strip will continue to be conveyed flat. Under the reaction force of the first telescopic rod and the first spring being squeezed, the sliding frame will be reset, which meets the needs of subsequent strip unwinding and flattening.

The outer wall of the second telescopic rod 12 is sleeved with a second spring 13 that is fixedly connected to the outer wall of the connecting frame 11.

The outer wall of the turntable 15 is rotatably connected to a pulling rod 16. One end of the pulling rod 16 is rotatably connected to a pressure rod 17 that is slidably connected to the outer wall of the connecting frame 11. A lifting groove 18 is provided at the connection between the outer wall of the connecting frame 11 and the pressure rod 17.
[0033] The setting of pressure bar 17 is beneficial for initially leveling the bent part of the material strip head.
[0034] The other end of the first spring 7 is fixedly connected to the outer wall of the cold rolling mill body 1, and the first telescopic rod 6 and the first spring 7 are symmetrically arranged on both sides of the sliding frame 5.
[0035] The fixed connection between the other end of the first spring 7 and the outer wall of the cold rolling mill body 1 facilitates the easy reset of the sliding frame 5 after use.
[0036] The threaded rod 9 is provided in two sets, and the two sets of threaded rod 9 rotate in opposite directions.
[0037] It is advantageous to set two sets of threaded rods 9 with opposite rotation directions, so as to drive the two sets of traction pressure plates 10 to slide relative to each other.

The material strip will pass through the conveyor roller 4 and be continuously conveyed on the cold rolling mill. At this time, the first servo motor 8 can be turned on, and the rotation of the threaded rod 9 will drive the traction pressure plate 10 to press and lift the bent part of the head. Under the continuous conveying of the material strip, the sliding frame 5 will slide along the outer wall of the cooler and squeeze the first telescopic rod 6 and the first spring 7. After the material strip head is flattened and conveyed again, the traction pressure plate 10 is loosened. At this time, the material strip will continue to be conveyed flat. Under the reaction action of the first telescopic rod 6 and the first spring 7 being squeezed, the sliding frame 5 will be reset, which meets the needs of subsequent material strip uncoiling and flattening.
