Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a platform idler type plasma cutting and blanking machine. Background Art

[0002] A plasma cutting machine is a processing equipment that uses the heat of a high-temperature plasma arc to locally melt the metal at the workpiece cutting edge, and discharges the molten metal by the momentum of the high-speed plasma to form a cutting edge; with different working gases, various metals that are difficult to cut by oxygen cutting can be cut.

[0003] The plasma cutting and blanking machine is disclosed in Chinese Patent CN219648917U authorized and announced on September 8, 2023. In this machine, the plate to be cut is placed on the conveyor roller, and the position of the plate is adjusted so that the cutting position is below the plasma cutting machine. Then, the positioning roller is rotated. During the rotation of the positioning roller, the distance between the surface of the positioning roller and the conveyor roller becomes closer and closer, and then the positioning roller contacts the surface of the plate, and the plate is fixed on the conveyor roller by the positioning roller. The structure is simple, which is convenient for clamping and fixing the plate and improves the clamping stability. However, when this device is in use, a small amount of waste residue will adhere to the conveyor roller. When the conveyor roller discharges materials, the workpiece will have intense friction with the conveyor roller through the waste residue. After long-term use, the scratches on the surface of the conveyor roller will gradually increase, resulting in an increase in friction force, making it still inconvenient to use. Summary of the Utility Model

[0016] (2) For this platform idler type plasma cutting and blanking machine, through the setting of the pressing component, when the workpiece is conveyed to the surface of the pressing plate by the conveying roller, the workpiece can lift the pressing plate through the pressing roller, and at the same time, through the thrust applied by the limiting spring on the surface of the connecting column, the pressing plate is pulled to press the surface of the workpiece. At the same time, due to the rotational connection between the pressing roller and the pressing plate, the pressing plate will not affect the conveying of the workpiece by the conveying roller during pressing, improving the overall usability of the device.

[0035] Embodiment 1

[0036] Please refer to Figure 1 - Figure 10 , as shown in the figure, a platform idler type plasma cutting and blanking machine includes a workbench 1 and a plasma cutting machine 5. A conveying roller 3 is fixedly connected to the surface of the workbench 1, a slag discharge plate 2 is fixedly connected to the outer wall of the workbench 1, and the surface of the slag discharge plate 2 is an inclined surface, so that when the waste slag falls onto the surface of the slag discharge plate 2, it can slide out through the inclined surface. A support frame 4 is fixedly connected to the surface of the workbench 1, a plasma cutting machine 5 is slidably connected to the surface of the support frame 4, and a cleaning assembly 6 is assembled on the inner wall of the conveying roller 3;

[0037] The cleaning component 6 includes a blowing pipe 601. The blowing pipe 601 is installed inside the conveying roller 3. A support column 604 is fixedly connected to the outer wall of the blowing pipe 601. The support column 604 can support the inner wall of the conveying roller 3, enhance the structural strength of the surface of the conveying roller 3, and improve the service life of the conveying roller 3. Blowing holes 602 are formed on the surface of the conveying roller 3. A limiting rod 603 is fixedly connected to the surface of the workbench 1, and the outer wall of one end of the limiting rod 603 is slidably connected to the inner wall of the conveying roller 3. A limiting block 605 is slidably connected to the outer wall of one end of the limiting rod 603. A groove 606 is formed on the outer wall of the limiting block 605. A connecting block 607 is fixedly connected to the outer wall of the limiting block 605. A connecting shaft 608 is fixedly connected to the outer wall of the limiting block 605. A rubber plug 609 is slidably connected to the outer wall of the connecting shaft 608, and the rubber plug 609 is slidably connected to the limiting rod 603. An exhaust hole 610 is formed on the outer wall of the rubber plug 609. An air inlet groove 611 is formed on the inner wall of one end of the limiting rod 603. A return spring 612 is fixedly connected to the surface of the limiting block 605, and one end of the return spring 612 is fixedly connected to the inner wall of the conveying roller 3. A connecting rod 613 is slidably connected to the inner wall of the blowing pipe 601. A piston 614 is fixedly connected to the outer wall of one end of the connecting rod 613. A connecting spring 615 is fixedly connected to the outer wall of the piston 614. A moving groove 616 is formed on the inner wall of the blowing pipe 601, and the inner wall of the moving groove 616 is slidably connected to the connecting block 607. A return groove 617 is formed on the inner wall of the blowing pipe 601, and one end of the return groove 617 is connected to one end of the moving groove 616. A connecting chute 618 is formed on the inner wall of the blowing pipe 601, and both ends of the connecting chute 618 are respectively connected to the moving groove 616 and the return groove 617.

[0038] During use, when the conveying roller 3 rotates, it can drive the air blowing pipe 601 to rotate synchronously, causing the moving groove 616 to squeeze the connecting block 607, thereby pushing the limiting block 605 to slide inside the air blowing pipe 601. When the limiting block 605 moves, due to the large friction force of the rubber plug 609, the limiting block 605 will slide inside the air blowing pipe 601 prior to the rubber plug 609, separating the limiting block 605 from the rubber plug 609 and releasing the limitation on the groove 606 and the exhaust hole 610. External air can enter the inside of the air blowing pipe 601 through the groove 606 and the exhaust hole 610. When the connecting block 607 slides to the other end of the moving groove 616, it will enter the reset groove 617. At this time, under the action of the reset spring 612, the limiting block 605 is pushed to slide inside the air blowing pipe 601. The surface of the limiting block 605 will first close with the surface of the rubber plug 609, limiting the groove 606 and the exhaust hole 610. Then, the rubber plug 609 is pushed to squeeze the air inside the air blowing pipe 601. At the same time, external air will enter the inside of the air blowing pipe 601 through the air inlet groove 611. The air will expand outward under extrusion and push the piston 614 to slide inside the air blowing pipe 601 through the connecting rod 613, thereby limiting the air blowing pipe 601, making the air inside the air blowing pipe 601 enter the inside of the conveying roller 3 and blow towards the surface of the adjacent conveying roller 3 through the air blowing holes 602. After the air is discharged, the connecting spring 615 is pulled by the force to reset the piston 614 and limit the air blowing pipe 601. At this time, through the continuous rotation of the air blowing pipe 601, the connecting block 607 slides inside the connecting chute 618 and re-enters the inside of the moving groove 616, enabling the limiting block 605 to repeat the above movement through the rotation of the air blowing pipe 601. By blowing air towards each other's surfaces between adjacent conveying rollers 3, it can effectively prevent waste residue from adhering to the conveying roller 3, thereby preventing the workpiece from generating intense friction with the conveying roller 3, affecting the blanking work of the workpiece, and improving the overall usability of the device.

[0039] Please refer to Figure 1 - Figure 7 As shown in the figure, a pressing assembly 7 is assembled on the outer wall of the workbench 1. The pressing assembly 7 includes a connecting groove 701, which is opened on the surface of the workbench 1. A limiting spring 702 is fixedly connected to the inner wall of the connecting groove 701. A connecting column 703 is fixedly connected to the outer wall of one end of the limiting spring 702. A pressing plate 704 is fixedly connected to the outer wall of the top of the connecting column 703. A pressing roller 705 is rotatably connected to the outer wall of the pressing plate 704.

[0040] During use, when the workpiece is conveyed to the surface of the pressing plate 704 by the conveying roller 3, the workpiece can jack up the pressing plate 704 through the pressing roller 705, enabling the pressing plate 704 to slide upward inside the connecting groove 701 through the connecting column 703 and compress the limiting spring 702. Meanwhile, the thrust applied by the limiting spring 702 on the surface of the connecting column 703 is used to pull the pressing plate 704 to press the surface of the workpiece. At the same time, due to the rotational connection between the pressing roller 705 and the pressing plate 704, the pressing plate 704 will not affect the conveyance of the workpiece by the conveying roller 3 during pressing, improving the overall usability of the device.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
