Description

Technical Field

[0001] This utility model relates to the field of aluminum coil equipment technology, specifically to a waste edge conveying device for an edge trimming machine. Background Technology

[0002] Waste edges cut by aluminum coil trimming equipment need to be pulled out of the equipment by a traction device for crushing or winding. For example, Chinese utility model patent CN218931196U discloses a waste edge traction device for aluminum coil trimming equipment, relating to the field of aluminum coil equipment technology. It includes a traction roller support, on which a traction roller is rotatably connected. The surface of the traction roller has a diamond-shaped grid pattern. A connecting plate is vertically mounted on the upper end of the traction roller support. An adjustment hole is opened at the top of the connecting plate, and an adjustment plate is rotatably connected to the adjustment hole. A nylon roller support is fixedly connected to the lower right end of the adjustment plate, on which a nylon roller is rotatably connected. A cylinder connecting block is fixedly connected to the right end of the nylon roller support, and a cylinder is rotatably connected to the cylinder connecting block. This device solves the problems of waste edge pressing and coil recutting, improving production efficiency and product yield, avoiding aluminum coil recutting or scrapping, reducing employee rework, and lowering labor intensity and equipment wear. The aforementioned authorized patent has the following problems: It lacks a metal waste edge guiding mechanism, causing the waste edge to easily shift laterally during transport. Although the support structures on both sides can limit the waste edge from sliding out significantly to some extent, this shift prevents the waste edge from maintaining a neat posture when entering the subsequent winding and recycling stage. Especially when the waste edge is narrow or the material is soft, the shifted waste edge is prone to interlayer misalignment and irregular stacking during winding, which not only increases the difficulty of winding but also results in uneven tightness of the wound waste edge, seriously affecting subsequent transportation, storage, and reprocessing, thus reducing the efficiency and quality of waste edge recycling. To address these problems, an innovative design is urgently needed based on the existing waste edge conveying device of the trimming machine. Utility Model Content

The guide mechanism includes a fixed plate 14, and a fixed plate 14 is fixed to the front and rear sides of the two side plates 2. A lead screw 15 is threaded through the interior of the fixed plate 14. One end of the lead screw 15 is located between the fixed plates 14 and rotatably connected to the middle of a U-shaped plate 16 via a bearing. The top and bottom of the U-shaped plate 16 are rotatably connected to the top and bottom of a guide wheel 19 via bearings. Second limiting rods 18 are fixed to both ends of the outer side of the U-shaped plate 16, and the ends of the second limiting rods 18 penetrate the interior of the fixed plate 14. A pressure regulating mechanism is provided between the pressure roller 6 and the top plate 3. The pressure regulating mechanism includes a cylinder 7. The cylinder 7 is fixedly inserted through the middle of the top plate 3. The bottom output end of the cylinder 7 is fixedly connected to the top center of the load-bearing plate 8. A first limiting rod 9 is fixed on both sides of the top of the load-bearing plate 8. The upper end of the first limiting rod 9 penetrates the interior of the top plate 3. The first limiting rod 9 and the top plate 3 are slidably connected. A pressure sensor 10 is provided in the middle of the lower surface of the load-bearing plate 8. A U-shaped frame 11 is provided below the pressure sensor 10. The two ends of the U-shaped frame 11 are rotatably connected to the two ends of the pressure roller 6 through bearings. A T-shaped rod 12 is fixed on both sides of the top of the U-shaped frame 11. The upper end of the T-shaped rod 12 penetrates the interior of both ends of the load-bearing plate 8. The T-shaped rod 12 and the load-bearing plate 8 are slidably connected. A spring 13 is nested and slidably provided at the lower end of the T-shaped rod 12. The spring 13 is located between the load-bearing plate 8 and the U-shaped frame 11.

[0017] A PLC controller 20 is installed on one side of the side plate 2. The PLC controller 20 is electrically connected to the servo motor 5, the cylinder 7 and the pressure sensor 10. A top plate 3 is welded and fixed between the top of the side plates 2. A traction roller 4 is rotatably installed between the side plates 2 through bearings. The end of the traction roller 4 passes through the interior of the side plate 2 and is fixedly connected to the output end of the servo motor 5. The outer wall of the servo motor 5 is fixed to the outside of the side plate 2 through a mounting plate.

[0018] The guide wheels 19 are evenly distributed inside the U-shaped plate 16. The other end of the lead screw 15 is fixed with screw plates 17 on both sides. The second limiting rod 18 is slidably connected to the fixed plate 14. The diameter of the guide wheel 19 gradually decreases from the end to the middle of the guide wheel 19. The design of the guide wheel 19 plays a role in limiting and guiding the waste edge.

[0019] The outer side of the second limit rod 18 is provided with scale lines, which makes it easy for operators to intuitively observe and adjust the moving distance of the U-shaped plate 16, ensuring the accuracy of the spacing adjustment of the guide wheels 19 on both sides and improving the guiding effect.

[0020] Both the traction roller 4 and the pressure roller 6 are fitted with anti-slip rubber sleeves on their outer sides, which can increase the friction between the traction roller 4, the pressure roller 6 and the waste edge, effectively prevent the waste edge from slipping during the transmission process, and ensure that the waste edge is stably traction and transmitted. At the same time, the anti-slip rubber sleeves are soft in texture, which can reduce the wear on the surface of the waste edge, ensure the integrity of the waste edge, and facilitate subsequent winding, recycling and reprocessing.

[0021] Working principle: When using the waste edge conveying device of the shearing machine, firstly, according to the width of the waste edge, the screw 15 is rotated by turning the screw plate 17. The screw 15 pushes the U-shaped plate 16 to move along the second limit rod 18. Combined with the scale line on the second limit rod 18, the distance between the two guide wheels 19 is adjusted to match the width of the waste edge, so that the waste edge can smoothly enter along the channel formed by the guide wheels 19. After the device is started, the servo motor 5 drives the traction roller 4 to rotate, and the PLC controller 20 controls the cylinder 7 to extend, pushing the load-bearing plate 8 down. Initially, there is a certain distance between the pressure sensor 10 and the U-shaped frame 11. As the load-bearing plate 8 descends, the pressure roller 6 moves downward first and contacts the waste edge on the traction roller 4. At this time, the U-shaped frame 11 stops moving downward, while the load-bearing plate 8 continues to descend, causing the spring 13 to be compressed. The spring 13 plays a good buffering role, preventing the pressure from being too high at any moment. Subsequently, the pressure sensor 10 continues to move downward with the load-bearing plate 8 until the bottom of the pressure sensor 10 contacts the top of the U-shaped frame 11. The pressure sensor 10 is squeezed, and then sends a pressure signal to the PLC controller 20. The PLC controller 20 adjusts the output of the cylinder 7 according to the preset pressure value to ensure that the pressure roller 6 exerts stable pressure on the waste edge. After the waste edge is output from the trimming device, it enters between the traction roller 4 and the pressure roller 6 under the guidance of the guide mechanism. It is transmitted under the action of friction. During the process, the guide wheel 19 ensures that the waste edge does not shift laterally and maintains a neat posture, preparing for subsequent winding and recycling. When the waste edge transmission is completed or the machine needs to be stopped, the PLC controller 20 controls the cylinder 7 to retract, which drives the load-bearing plate 8 to rise. The pressure sensor 10 separates from the U-shaped frame 11, the spring 13 gradually resets, the pressure roller 6 rises and disengages from the traction roller 4, and at the same time the servo motor 5 stops working, completing the transmission cycle.
