Description

Technical Field

[0001] This utility model relates to a steel coil uncoiling device. Background Technology

[0002] When uncoiling a steel coil, it is placed on an uncoiling frame. After being pulled out, the coil is conveyed backward through a clamping and conveying structure. However, steel coils are relatively heavy. If the distance between the uncoiling frame and the conveying structure is too close, it is not conducive to coil changing operations. If the distance is too far, the suspended steel plate in the middle is prone to collapsing and dragging on the ground, causing wear on the surface of the steel plate and even slipping backward. Existing uncoiling devices will install a support plate on the conveying structure to lift the steel plate to a certain extent and prevent it from sliding down. However, due to space limitations, the length that can be supported is limited, and the effect is singular. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a steel coil uncoiling device, which can effectively support the uncoiling of steel plates and increase the distance between uncoiling and conveying.

[0004] To achieve this objective, the structure adopted by this utility model is as follows: a steel coil uncoiling device, including an uncoiling frame and a conveying frame. The uncoiling frame is provided with an uncoiling shaft and a first pressure roller. The conveying frame is provided with a conveying roller and a second pressure roller. A support plate is provided below the conveying roller. The two sides of the support plate are connected to the two ends of the connecting shaft of the conveying roller through swing arms. The surface of the support plate is a hollow plate with air holes. The surface of the support plate is connected to a negative pressure machine through a pipe.

[0005] The first pressure roller is connected to the unwinding frame via the first rotating frame. The first pressure roller is positioned above the unwinding shaft. The first rotating frame is connected to a hydraulic structure to drive the first rotating frame to swing. One end of the unwinding shaft is connected to the unwinding frame, and the other end is supported by a support arm. The support arm is connected to a support base via a hydraulic structure.

[0006] The second pressure roller is positioned above the conveyor roller, and a second rotating frame is positioned at the top of the conveyor frame. The center of the second rotating frame is connected to the conveyor frame via a rotating shaft. One end of the second rotating frame is connected to the second pressure roller, and a hydraulic structure is provided between the other end and the conveyor frame.

[0007] One end of the support plate is connected to the connecting shaft of the conveyor roller via a swing arm, and the other end is equipped with a hydraulic structure to connect to the conveyor frame.

[0008] A heating plate is provided on the surface of the support plate, and heating wires are coiled inside the heating plate.

[0009] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. The steel coil is supported by the support plate from the uncoiling frame to the conveyor frame. The negative pressure on the plate surface causes the steel plate to be adsorbed onto the support plate, which can keep the steel plate between the uncoiling frame and the support plate in a certain tension state, preventing the steel plate from slipping due to the loss of tension at the rear. At the same time, it can increase the distance between the uncoiling frame and the conveyor frame, which is conducive to the daily maintenance of equipment and the replacement of steel coils.

[0015] like Figure 1The steel coil uncoiling device shown includes an uncoiling frame 2 and a conveyor frame 7. The uncoiling frame 2 is equipped with an uncoiling shaft 3 and a first pressure roller 5. The first pressure roller 5 is connected to the uncoiling frame 2 via a first rotating frame 4 and is positioned above the uncoiling shaft 3. The first rotating frame 4 is connected to a hydraulic structure that drives it to swing. One end of the uncoiling shaft 3 is connected to the uncoiling frame 2, and the other end is supported by a support arm 6. One end of the support arm 6 has a semi-circular groove, and the end of the uncoiling shaft 3 is positioned within this groove. The other end is connected to a support base 13 via a hydraulic structure. The conveyor frame 7 is equipped with a conveyor roller 10 and a second pressure roller 9. Both ends of the conveyor roller 10 are connected to the conveyor frame via connecting plates, and the conveyor roller 10 is connected to a rotating motor. The second pressure roller 9 is positioned above the conveyor roller 10. A second rotating frame 8 is positioned at the top of the conveyor frame 7, and the center of the second rotating frame 8 is connected to the conveyor frame 7 via a rotating shaft. One end of the second rotating frame 8 is connected to the second pressure roller 9, and a hydraulic structure is provided between the other end and the conveyor frame 7. The hydraulic structure drives the second rotating frame 8 to swing, thus causing the second pressure roller 9 to swing up and down. A support plate 11 is provided below the conveyor roller 10. The two sides of the support plate 11 are connected to the two ends of the connecting shaft of the conveyor roller 10 through swing arms. The surface of the support plate 11 is a hollow plate with air holes 12. The surface of the support plate 11 is connected to a negative pressure machine through a pipe.

[0016] The steel coil is supported by the support plate 11 as it moves from the unwinding frame 2 to the conveyor frame 7. Under the action of the negative pressure machine, the steel plate is adsorbed onto the support plate 11 through the air holes 12, which can keep the steel plate between the unwinding frame 2 and the support plate 11 in a certain tension state, preventing the steel plate from slipping due to loss of tension at the rear. At the same time, it can increase the distance between the unwinding frame 2 and the conveyor frame 7, which is conducive to daily equipment maintenance and steel coil replacement.

[0017] One end of the support plate 11 is connected to the connecting shaft of the conveyor roller 10 via a swing arm, and the other end is provided with a hydraulic structure to connect to the conveyor frame 7. The rotation angle of the support plate 11 can be adjusted by the hydraulic structure, thereby adjusting the tension of the steel plate between the uncoiling frame 2 and the feeding frame 7.

[0018] A heating plate is provided on the surface of the support plate 11, and heating wires are coiled inside the heating plate. When the steel plate passes through the support plate 11, the heating plate can preheat the steel plate, which is beneficial for subsequent coating and film processing.

[0019] The unwinding frame 2 and the conveyor frame 7 are mounted on the base 1. A track and a drive structure are mounted on the base 1. The unwinding frame 2 and the conveyor frame 7 are connected to the track. The unwinding frame 2 or the conveyor frame 7 is connected to the drive structure. The drive structure can adaptively adjust the distance between the unwinding frame 2 and the conveyor frame 7.
