When in use, the strip steel needs to be cut into corresponding width and length according to the use requirements. When the strip steel is cut, the steel coil needs to be unfolded by the unwinding equipment, and then the unfolded strip steel is transported to the cutting equipment via the conveying equipment. During the transportation of the strip steel on the conveying equipment, the strip steel sometimes deviates. Once the strip steel is deviated and not discovered, the cutting seam of the last cut strip steel will be tilted, resulting in the strip steel becoming waste after cutting. This will cause waste of strip steel and affect the cutting efficiency of the strip steel, which brings great inconvenience to the processing of strip steel. Utility Model Content

[0016] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, unless there is a conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-4 As shown, the anti-deflection mechanism for strip cutting described in this embodiment includes a frame 1 arranged between the uncoiling equipment and the cutting equipment, and a plurality of conveying rollers 2 are evenly distributed on the frame 1 along the front and rear directions. The conveying rollers 2 are driven to rotate by a motor 3. A lifting plate 4 is provided on the frame 1 at a position above the corresponding conveying roller 2, and the lifting plate 4 is provided with a synchronously adjustable movable seat 5 on its left and right sides. The movable seat 5 is provided with a downwardly extending mounting vertical rod 6, and the lower ends of the mounting vertical rods 6 on both sides are provided with anti-deflection components on the side opposite to each other, and the anti-deflection components correspond to the two sides of the strip 19. The anti-deflection components can control the motor 3 to stop operating, and the mounting vertical rod 6 is also provided with a mounting support rod 7 on the side opposite to each other, and the mounting support rod 7 is also provided with a pressure wheel group, which presses the surface of the strip 19.

[0019] The anti-deflection component includes a mounting plate 8 arranged on the mounting vertical pole 6, and a plurality of elastic inclined swing plates 9 are evenly distributed on the opposite sides of the mounting plate 8. A proximity switch 10 is arranged on the mounting plate 8 at a position corresponding to the inclined end of the swing plate 9. The sensing head of the proximity switch 10 is arranged toward one side of the swing plate 9, and a sensing block 11 is provided on the swing plate 9 at a position corresponding to the sensing head of the proximity switch 10. The sensing block 11 contacts the proximity switch 10 and controls the motor 3 to stop operating.

[0020] A hinge shaft 12 is provided on the mounting plate 8, the front end of the swing plate 9 is hinged to the hinge shaft 12, and the rear end of the swing plate 9 is tilted toward the side of the strip steel 19. The proximity switch 10 is provided at a position corresponding to the rear end of the swing plate 9. A return spring 13 is provided on the mounting plate 8 at a position between the corresponding hinge shaft 12 and the proximity switch 10. One end of the return spring 13 is fixedly connected to the mounting plate 8, and the other end of the return spring 13 is fixedly connected to the swing plate 9. The return spring 13 makes the swing plate 9 in an inclined state. When the swing plate 9 is collided with the external strip steel 19, the swing plate 9 will squeeze the return spring 13. After the collision is resolved, the swing plate 9 will be reset under the action of the return spring 13.

[0021] The pressing wheel group includes a wheel frame 14 provided with the lower end of the mounting support rod 7 , and a plurality of pressing wheels 15 are evenly distributed in the wheel frame 14 , and the pressing wheels 15 press on the surface of the strip steel 19 .

[0022] Lifting cylinders 16 are provided on both sides of the frame 1. The piston rod of the lifting cylinder 16 is set vertically upward. The lifting plate 4 is installed at the end of the piston rod of the lifting cylinder 16. By controlling the extension and retraction of the piston rod of the lifting cylinder 16, the lifting plate 4 can be moved up and down. In this way, the position of the anti-deflection component and the pressure wheel group can be adjusted according to the thickness of the strip steel. Raising the position of the lifting plate 4 also makes it convenient for the staff to inspect and repair the anti-deflection component and the pressure wheel group.

[0023] A forward and reverse screw 17 is placed horizontally on the top of the lifting plate 4, and the movable seat 5 is arranged on both sides of the opposite thread directions of the forward and reverse screw 17. A horizontal movable notch 4a is provided on the lifting plate 4 at the position corresponding to the movable seat 5, and the mounting rod 6 passes through the movable notch 4a and extends downward.

[0024] The forward and reverse lead screws 17 are driven to rotate by a servo motor 18 .

[0025] When the servo motor 18 drives the forward and reverse screws 17 to rotate forward and reverse, the movable seats 5 on both sides will simultaneously move toward the center of the frame 1, or the movable seats 5 on both sides will move away from each other, so that the gaps between the movable seats 5 on both sides can be synchronously adjusted.

[0026] The working principle of the present invention is as follows: the frame 1 of the anti-deviation mechanism is placed between the unwinding device and the cutting device, with the front side of the frame 1 facing the end of the unwinding device and the rear side of the frame 1 facing the feed end of the cutting device. The steel strip 19 is first conveyed to the conveying roller 2 in the frame 1 via the unwinding device, and the steel strip is further conveyed to the cutting device via the conveying roller 2. Before the equipment is started, the servo motor 18 and the lifting cylinder 16 are controlled to move according to the specifications of the steel strip, so as to adjust the position of the anti-deviation component and the pressure wheel group, so that the pressure wheel 15 on the pressure wheel group is pressed against the upper end surface of the steel strip 19, and the swing plates 9 in the anti-deviation components arranged in a mirror image on both sides are located on both sides of the steel strip 19, and a small gap is left between the inclined end of the swing plate 9 and both sides of the steel strip 19. When the steel strip 1 9 During normal transportation, the strip steel can be smoothly transported to the cutting equipment via the conveying roller 2 for normal cutting operation. Once the strip steel 19 is deflected, the strip steel will collide with the corresponding swing plate 9 on the side of the deflection direction. Under the action of the external force of the strip steel 19, the swing plate 9 will rotate outward, so that the sensing block 11 on the swing plate 9 contacts the sensing head of the proximity switch 10 on the mounting plate 8, so that the proximity switch 10 sends a signal to control the motor 3 to stop operating. At this time, the conveying roller 2 no longer works, thereby effectively preventing the deflected strip steel 19 from directly entering the cutting equipment for cutting, avoiding the generation of waste, and also preventing the deflected strip steel from rubbing against the equipment during transportation, avoiding wear of the equipment and the strip steel itself.

[0027] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
