Technical Field

[0001] The utility model relates to the technical field of steel strip longitudinal shearing, in particular to a coil material anti-drag bottom device for steel strip longitudinal shearing equipment. Background Art

[0002] In the metal processing industry, longitudinal shearing equipment is a commonly used steel strip cutting equipment, which can usually cut wide steel strips into specific widths. However, during the longitudinal shearing process, since the cut steel strip coils are arched, warped and have side waves during transportation, the cut steel strip coils need to be buffered through a looper pit so that the subsequent tension table in front of the coiler can feed the steel strip into the coiler in an orderly manner to avoid the problem of long and short strips and ensure the quality of the coils. In the prior art, the steel strip coils may bottom out in the looper pit for various reasons, which not only affects product quality and production efficiency, but also causes damage to the equipment and even poses a safety threat to the operator. Therefore, there is an urgent need for a coil anti-bottoming device for steel strip longitudinal shearing equipment. Utility Model Content

[0020] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0021] like Figures 1 to 3As shown, the utility model discloses a device for preventing coils from dragging at the bottom of a steel strip longitudinal shearing device, comprising two support plates 2 arranged on the inner walls on both sides of a loop pit 1, wherein the two support plates 2 are symmetrically arranged along the coil conveying direction, and each support plate 2 is adjustably arranged in the loop pit 1 through a driving member; in an initial state, the two support plates 2 are arranged in an inclined state from top to bottom, and the bottom ends of the two support plates 2 are in a non-contact state, so as to provide a flexible buffer space for the bottom of the steel strip coil entering the loop pit 1, thereby ensuring that the steel strip coil is lifted and supported while avoiding excessive restrictions on the steel strip coil, thereby ensuring the orderly conveying of the steel strip coil by the subsequent coiler and the tension table; an infrared sensor 3 is arranged at the bottom of the loop pit 1 between the two support plates 2, and the infrared sensor 3 is connected to a controller for controlling the longitudinal shearing device and the driving member. During operation, when the equipment on both sides of the loop pit 1 deviates from the operation, the steel strip coil in the loop pit 1 will fall along the inclined surface of the support plate 2. At this time, the distance between the bottom of the steel strip coil and the infrared sensor 3 is reduced. When this distance reaches the height that the infrared sensor 3 can detect, the infrared sensor 3 outputs a signal to the controller, and the controller controls the drive component to lift the support plate 2 to raise the height of the steel strip coil to avoid the steel strip coil from dragging on the bottom; at the same time, the controller transmits the signal to the PLC control system that controls the longitudinal shearing equipment, slows down the longitudinal shearing equipment and issues an alarm to remind the workers to adjust it in time to ensure the shearing quality of the subsequent coils.

[0022] The top of the support plate 2 is hinged to the inner wall of the looping pit 1, and the driving member is a cylinder 4 hinged to the inner wall of the looping pit 1. The cylinder 4 is connected to the air source through an air pipe, and the telescopic end of the cylinder 4 is hinged to the bottom of the support plate 2. When working, by turning on the cylinder 4, the cylinder 4 pushes the support plate 2 to rotate upward along the hinge point to lift the steel strip coil, effectively avoiding the occurrence of the steel strip coil dragging the bottom, and also avoiding the steel strip coil being scratched.

[0023] Furthermore, a plurality of accommodating grooves 5 are provided at the top of each support plate 2, and a sliding roller 6 is rotatably provided in the accommodating groove 5. The provision of the sliding roller 6 can reduce the friction between the steel strip coil and the support plate 2 during the movement, and avoid damage to the surface of the steel strip coil. In addition, a U-shaped notch 14 is provided at the bottom of the support plate 2, and a supporting roller 7 is rotatably provided in the notch 14. The provision of the supporting roller 7 can reduce the formation of an arc-shaped transition surface at the bottom of the support plate 2, so as to reduce the wear on the steel strip coil, and at the same time facilitate the movement and transportation of the steel strip coil.

[0024] Furthermore, guide rollers 8 are rotatably provided on both sides of the top of the pallet 2 along the width direction, and multiple guide rollers 8 are arranged at intervals on both sides of the pallet 2; the arrangement of the guide rollers 8 can provide limiting guidance for the movement of the steel strip coil to prevent the steel strip coil from being offset during transportation. In addition, a limiting roller 9 is rotatably provided at a position close to the top of the pallet 2 to provide limiting for the steel strip coil in the input and output loop pits 1 to prevent it from stretching upward, thereby ensuring the stable transportation of the steel strip coil. Preferably, the limiting roller 9 is elastically arranged on the pallet 2 to provide a buffer space for the transportation of the steel strip coil, thereby preventing the limiting roller 9 from restricting the steel strip coil too tightly or too loosely, thereby affecting the stable transportation of the steel strip coil.

[0025] Specifically, the support plate 2 is provided with support seats 10 on both sides along the width direction, and a slide groove 12 is provided on the support seat 10 for the support block 11 to slide. A buffer spring 13 is fixedly provided on the top of the support block 11, and the top of the buffer spring 13 is fixedly connected to the top wall of the slide groove 12. In addition, a guide rod 15 is provided on the top of the support block 11, and the top of the guide rod 15 is movably extended from the slide groove 12 to provide guidance for the movement of the support block 11; the buffer spring 13 is sleeved on the outside of the guide rod 15.

[0026] When the utility model is working, when the equipment operation on both sides of the loop pit 1 deviates, the steel strip coil in the loop pit 1 will fall along the inclined surface of the support plate 2. At this time, the distance between the bottom of the steel strip coil and the infrared sensor 3 is reduced. When this distance reaches the height that the infrared sensor 3 can detect, the infrared sensor 3 outputs a signal to the controller, and the controller controls the driving part to lift the support plate 2 to raise the height of the steel strip coil to avoid the steel strip coil from dragging on the bottom; at the same time, the controller transmits the signal to the PLC control system that controls the longitudinal shearing equipment, slows down the longitudinal shearing equipment and issues an alarm to remind the workers to adjust it in time to ensure the shearing quality of the subsequent coils.
