Shearing waste processing device for automatic compound round knife plate shearing machine

Abstract

This invention discloses a waste material processing device for an automatic double-blade circular shearing machine, including a base with a worktable on top. The waste material processing device is located at one end of the shearing machine's discharge point. After the shearing machine cuts the metal sheet, the finished sheet continues to move via a first guide roller and a second guide roller, while the generated waste material is guided to a recycling bin via a guide pipe. A drive mechanism drives a crushing roller and a spiral feeding rod, with the crushing rollers rotating in opposite directions. Through interlocking, they crush the waste material, which falls into an arc-shaped trough and is discharged through a discharge pipe via the spiral feeding rod. The discharge pipe opening can be equipped with a conveying device (existing common equipment, therefore not described in detail). This allows for the automatic processing and conveying of the strip-shaped waste material generated by the shearing machine, requiring no manual intervention throughout the process. This not only reduces the labor intensity of workers but also prevents waste material from injuring them, improving the efficiency of processing strip-shaped waste material.

Description

Technical Field

[0001] This invention relates to the field of waste treatment technology for shearing machines, specifically to a waste treatment device for an automatic double-blade circular shearing machine. Background Technology

[0002] The automatic double-blade circular shearing machine is a shearing equipment that adopts a double-blade circular structure and has an automatic unloading function. It is mainly used for efficient and precise shearing of metal sheets. When shearing the sheet, strip-shaped waste edges are generated.

[0003] Existing circular shearing machines produce scrap edges that fall directly to both sides during the shearing of metal sheets, requiring manual cleaning. However, existing scrap handling devices are unsuitable for these strip-shaped scrap edges, leaving only manual processing. This method cannot automatically handle the strip-shaped metal scrap edges, and manual cleaning is not only laborious but also prone to causing scratches from the sharp edges. Therefore, we propose an automatic double-blade circular shearing machine scrap handling device to solve this problem. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention discloses a waste edge processing device installed at one end of the shearing machine's discharge point.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see Figures 1 to 6 This invention provides a technical solution: a shearing waste processing device for an automatic double-blade circular shearing machine, comprising a base 1, a worktable 2 disposed on the top of the base 1, and the worktable 2 being fixedly connected to the four corners of the base 1 by support rods 3, wherein... A recycling bin 4 is installed on the top of one side of the base 1. The top center of the recycling bin 4 has a bin opening 5. A through opening 6 is provided on the workbench 2 corresponding to the bin opening 5. Guide pipes 7 are symmetrically arranged on the top of both sides of the workbench 2 corresponding to the through opening 6. The spacing between the guide pipes 7 is adjusted by an adjustment mechanism. The top of the longer side of the workbench 2 is symmetrically rotatably connected to the first guide roller 15 and the second guide roller 16. The recycling bin 4 is symmetrically connected to the crushing roller 17 near the top. The bottom inner side of the recycling bin 4 is provided with an arc-shaped groove 18. One end of the recycling bin 4 corresponding to the arc-shaped groove 18 is connected to the discharge pipe 19. The arc-shaped groove 18 is rotatably connected to the spiral feeding rod 20. The crushing roller 17 and the spiral feeding rod 20 are driven by a drive mechanism to work. The waste edge processing device is installed at one end of the shearing machine's discharge point. After the shearing machine cuts the metal sheet, the finished sheet continues to move through the first guide roller 15 and the second guide roller 16, while the generated waste edge is guided to the recycling box 4 through the guide pipe 7. The drive mechanism drives the crushing roller 17 and the spiral feeding rod 20. The crushing rollers 17 rotate in opposite directions and crush the waste edge through biting. The crushed waste falls into the arc-shaped groove 18 and is discharged through the discharge pipe 19 by the spiral feeding rod 20. The opening of the discharge pipe 19 can be equipped with a conveying device (existing common equipment, so it is not described in detail). This device can automatically process and convey the strip-shaped waste edge generated by the shearing machine without manual intervention. This not only reduces the labor intensity of the workers but also avoids the waste edge from injuring the workers and improves the processing efficiency of the strip-shaped waste edge.

[0021] Please see Figures 1 to 6 The guide tube 7 is rectangular and L-shaped. The two ends of the guide tube 7 face the first guide roller 15 and the recycling box 4 respectively. This ensures that the waste edge is smoothly and accurately guided from the shearing machine's output end into the recycling box 4, preventing the waste edge from scattering or deviating from the path, and improving the reliability and continuity of waste collection.

[0022] Please see Figures 1 to 6 The adjustment mechanism includes a support 8. The support 8 is fixedly connected to the top of the worktable 2 near the guide pipe 7. A sliding seat 9 is provided above the guide pipe 7 on the support 8. A groove 10 is formed on the top of the sliding seat 9 corresponding to the support 8. A slider 11 is fixedly connected to the bottom of the groove 10 corresponding to the sliding seat 9. A lead screw 12 is rotatably connected inside the groove 10. A servo motor 13 is installed at one end of the support 8. The shaft end of the servo motor 13 is fixedly connected to the lead screw 12. The sliding seat 9 is fixedly connected to the guide pipe 7 via a fixing rod 14. The lead screw 12 has two opposite external threads. The lead screw 12 is threadedly connected to the sliders 11 on both sides through two opposite external threads. The lead screw 12 can be driven to rotate by the servo motor 13, which drives the sliding seats 9 on both sides and the guide tubes 7 to move along the slide 10, thereby adjusting the distance between the guide tubes 7 on both sides. This can be adjusted according to the width of the finished sheet after shearing, so as to guide the waste edges of finished sheets of different widths into the recycling box 4, which improves the versatility and adjustment convenience of the device. In addition, accordion covers can be installed on both sides of the sliding seat 9 to cover the opening of the slide 10 and prevent debris from falling into the slide 10.

[0023] Please see Figures 1 to 6The bottom of the arc-shaped groove 18 is semi-circular, and the inner diameter of the arc-shaped groove 18 is equal to the inner diameter of the discharge pipe 19. The inner diameter of the arc-shaped groove 18 also matches the outer diameter of the screw feed rod 20. The inner walls of the recycling box 4 on both sides above the arc-shaped groove 18 are inclined, and the inner walls are inclined downwards towards the arc-shaped groove 18. The bottom of the arc-shaped groove 18 adopts a semi-circular design, and its inner diameter is equal to the inner diameter of the discharge pipe 19 and matches the outer diameter of the screw feed rod 20. This allows the screw feed rod 20 to form a good fit with the inner wall of the arc-shaped groove 18 when rotating, reducing waste residue, improving conveying efficiency, and avoiding blockage or poor conveying caused by excessive gaps. After the waste edge is crushed, it can fall smoothly into the arc-shaped groove 18 through the inclined interior.

[0024] Please see Figures 1 to 6 The drive mechanism includes transmission gears 21. Each crushing roller 17 has a transmission gear 21 fixedly connected to the same end, and the transmission gears 21 mesh with each other. A reduction motor 22 is installed on the base 1 near the recycling box 4. A first pulley 23 is installed on the shaft end of the reduction motor 22. A second pulley 24 is fixedly connected to one end of the crushing roller 17 away from the transmission gear 21. The first pulley 23 and the second pulley 24 are connected by a transmission belt 25. A first gear 26 is fixedly connected to the shaft end of the spiral feed rod 20 corresponding to one end of the transmission gear 21. A second gear 27 is fixedly connected to the shaft end of one of the transmission gears 21. The first gear 26 and the second gear 27 are connected by a toothed belt 28. Next, a guide frame 29 is symmetrically fixedly connected below the box opening 5 of the recycling box 4. The channel formed between the guide frames 29 is located directly above the crushing roller 17. It can use the geared motor 22 to drive a set of crushing rollers 17 to rotate via belt drive. Then, through the meshing transmission gear 21, the two crushing rollers 17 can achieve synchronous reverse rotation, thereby forming an effective bite crushing of the waste edge. The structure is compact and the transmission is smooth. Through the cooperation of the first gear 26, the second gear 27 and the toothed belt 28, the spiral feeding rod 20 and the crushing roller 17 share the same geared motor 22 for drive. There is no need to set up an additional power source, which simplifies the overall structure, reduces manufacturing costs and control complexity, and ensures the synchronization of feeding and crushing actions.

[0025] Working Principle: When using this automatic double-blade circular shearing machine's waste material processing device, firstly, install the base 1 and worktable 2 at one end of the shearing machine's discharge point. Based on the width of the processed metal sheet and the width of the generated waste edge, start the servo motor 13. The servo motor 13 drives the lead screw 12 to rotate. The two opposite external threads on the lead screw 12 respectively drive the two side sliders 11 to move synchronously towards or away from each other within the slide groove 10. The sliders 11 drive the sliding seat 9, and the sliding seat 9 drives the guide tube 7 to move via the fixed rod 14, thereby precisely adjusting the distance between the two guide tubes 7 to match the width of the waste edge. When the shearing machine cuts the metal sheet, the finished sheet continues to be conveyed forward along the top of the workbench 2 via the first guide roller 15 and the second guide roller 16, while the strip-shaped waste edges generated on both sides enter the L-shaped guide pipe 7. The guide pipe 7 guides the waste edges from the opening 6 of the workbench 2 through the opening 5 of the recycling box 4 into the inside of the recycling box 4. Under the gathering and guiding action of the guide frame 29, the waste edges fall accurately between the two crushing rollers 17. Start the reduction motor 22, which drives the first pulley 23 to rotate. The first pulley 23 drives the second pulley 24 to rotate via the transmission belt 25. The second pulley 24 drives one of the crushing rollers 17 to rotate. The crushing roller 17 drives the other crushing roller 17 to rotate synchronously in the opposite direction via the transmission gear 21 meshing at its end. The two crushing rollers 17 mesh with each other to continuously crush the incoming strip-shaped waste edge into smaller fragments. The crushed waste falls under the influence of gravity and slides along the inclined inner wall of the recycling box 4 into the arc-shaped groove 18 at the bottom. At the same time, the second gear 27 at one end of the shaft of the crushing roller 17 drives the first gear 26 to rotate through the toothed belt 28. The first gear 26 drives the spiral feed rod 20 to rotate in the arc-shaped groove 18. When the spiral feed rod 20 rotates, it pushes the crushed waste in the arc-shaped groove 18 to one end, so that it is discharged through the discharge pipe 19. The opening of the discharge pipe 19 can be connected to a conveying device as needed to transport the crushed waste to the designated collection position. In the whole process, the guidance, crushing, conveying and discharge of the waste edge are all completed automatically without manual intervention, realizing the efficient treatment of strip-shaped waste edge.
