Description

Technical Field

[0001] The utility model relates to a high-efficiency back-of-cut bridge device, belonging to the technical field of metal plate strip bridge devices. Background Art

[0002] The back-of-the-knife bridge device is an essential and important piece of equipment in metal coil slitting production and processing equipment. Due to the characteristics of sheet metal processing, the thickness of the coil varies across its width. This manifests as thicker in the middle and thinner at the edges, with the difference being approximately 1%. After the metal coil is sheared, slit, and re-reeled, the outer diameter of the coil in the middle is larger than that at the edges, resulting in uneven coil lengths, with the coiled length in the middle being longer than that at the edges. Therefore, in shearing and slitting production lines, a deep looping pit—typically 6-10 meters deep and 3-4 meters long—is required after slitting to store excess coil at the edges. Therefore, in metal coil shearing and processing equipment, a looping pit is always present between slitting and re-reeling. The device that allows the coil to pass through the looping pit is called the back-of-the-knife bridge device.

[0003] like Figure 1 、 2 As shown, it includes a shaft, rollers, a support plate, a fixed plate, a pin, a bridge frame, a cylinder base, and a hydraulic cylinder. The shaft passes through the rollers and is fixed to the bridge frame with bearings. Both ends of the shaft are fixed with fixed plates, and the bridge frame is laid with the support plate. The bottom end of the foundation is equipped with a cylinder base. One end of the hydraulic cylinder is fixed to the cylinder base, and the other end is fixed to the bottom of the bridge frame with a pin, which is used to control the bridge frame's lifting and lowering.

[0004] Existing post-cutting bridge systems typically utilize a flap structure that rises when coils pass through and lowers during processing, creating a loop to store coils of varying lengths. Existing post-cutting bridges are all fixed platforms and rollers, with no other power source besides a hydraulic cylinder that drives the guide plate up and down. For thick plate (over 0.8mm), the shear force of the slitting machine allows the coil surface to be smoothly conveyed to the feed rollers for subsequent processing. Conversely, thinner plate (under 0.8mm) is more difficult to convey forward after shearing because the shear force is relatively weak, resulting in less forward conveying force and difficulty in moving the plate forward. Furthermore, multiple thin strips of plate are prone to arching during conveyance. The friction between the strips and the bridge surface is significant, hindering forward movement. Consequently, manual assistance is often required to ensure forward conveyance. When slitting narrow strips, this results in low propulsion efficiency and poses safety risks when working near edges.

DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 3As shown, in this embodiment, a high-efficiency post-cutting bridge device includes a bridge frame 14, with fixed plates 18 symmetrically arranged on both sides of the inlet of the bridge frame 14. The fixed plates 18 are hinged to the shearing equipment through pins. A base cylinder seat 16 is arranged at the bottom end of the base, and a bridge cylinder seat 15 is arranged at the bottom of the bridge frame 14. The cylinder body of the hydraulic cylinder 17 is hinged to the base cylinder seat 16. The extension rod of the hydraulic cylinder 17 is hinged to the bridge cylinder seat 15. The hydraulic cylinder 17 drives the bridge frame 14 to rotate around the hinge point, so that the bridge 14 is raised or lowered. An inlet roller 2 is arranged between the two fixed plates 18. The inlet roller is mounted on the inlet shaft 1. The two ends of the inlet shaft 1 are mounted on the two fixed plates 18 and fixed to the fixed plates 18 on the corresponding side through imported bearings. A plurality of support plates 7 are laid on the top surface of the bridge frame 14. The plurality of support plates 7 are connected end to end along the length direction of the bridge frame 14. Behind the inlet roller 2, parallel driving rollers 6 and driven rollers 11 are installed. The driving roller 6 is mounted on a driving shaft, with both ends of the driving shaft secured to the bridge frame 14 via driving bearings. The driven roller 11 is mounted on a driven shaft 10. Connecting plates 9 are symmetrically located on either side of the bridge frame 14's outlet, with both ends secured to the two connecting plates via driven bearings. A conveyor belt 8 is mounted between the driving and driven rollers, rotating between them. A support plate 7 is located at the bottom of the upper conveyor belt, supporting it and ensuring the material passes parallel to the conveyor belt. A motor mount is fixed to the side of the bridge frame, housing a hydraulic motor. The motor's output shaft is fixedly connected to the driving shaft. When thin or soft material passes through the loop, the hydraulic motor drives the driving shaft, which in turn rotates the driving rollers, the conveyor belt, and the driven rollers. The conveyor belt then transports the material head to the downstream separation equipment and tension winding device.

[0019] like Figure 4 As shown, the bottom of the bridge is equipped with three supporting rollers, arranged parallel to the length of the bridge. The supporting rollers are mounted on corresponding supporting shafts, and the ends of the supporting shafts are fixed to the bottom of the bridge via supporting bearings. Adjacent supporting rollers are staggered up and down, so that the supporting rollers on the lower layer are located on top of the conveyor belt on the lower layer, and the supporting rollers on the upper layer are located on the bottom of the conveyor belt on the lower layer. The staggered arrangement of the supporting rollers is to adjust the tightness of the conveyor belt and prevent the conveyor belt from running off.

[0020] The connecting plate has multiple connection holes evenly spaced along its length. Mounting holes are provided on either side of the bridge's exit. The connecting plate is moved so that the connection holes align with the mounting holes and then secured with bolts. This allows for adjustment of the spacing between the active and passive conveyor rollers, and the tightness of the conveyor belt.

[0021] The hydraulic cylinder controls the bridge frame's rotation around the hinge point, enabling it to be raised and lowered. The conveyor belt operates as needed. When thinner or softer materials are sheared to the loop position by the knife holder, the motor drives the drive shaft to rotate, driving the conveyor belt. The conveyor belt transports the material head to the subsequent separation equipment and tension winding device. This application has a simple structure and is easy to operate, achieving automatic and rapid material transfer, saving time and effort, improving production efficiency and operator safety.

[0022] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
