Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a feeding device for laser cutting machines. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material eventually forms a slit, thereby achieving the purpose of cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam, and has the characteristics of high precision, fast cutting, no limitation on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs.

[0003] At present, when plate-shaped materials need to be cut by a laser cutting machine, the plates usually need to be transported by a loading device. However, the loading device used in the existing laser cutting machine cannot limit the conveying path of the plates, making it easy for the plates to shift during the conveying process. Utility Model Content

[0006] Furthermore, the support assembly includes a threaded barrel, the inner side of which is threadedly connected to a screw rod, and a foot is fixedly connected to the bottom of the screw rod.

[0007] Furthermore, a limiting groove matched with the guide rail is provided on the support seat, and a roller is installed inside the limiting groove.

[0008] Furthermore, a linear motor for driving the movable frame to move is installed on one side of the outer portion of the U-shaped frame, and a connecting plate fixedly connected to the support seat is installed on the moving subassembly of the linear motor.

[0009] Furthermore, the bottom surface of the limiting plate is in contact with the top surface of the conveyor belt, and a folded edge is provided at one end of the limiting plate close to the movable frame, and the two limiting plates are in an eight-shaped structure.

[0010] Furthermore, a support block is fixedly connected to the outer side of one end of the limit plate close to the extension plate, a positioning column is fixedly connected to the top of the support block, and a threaded rod is fixedly connected to the top of the positioning column, a nut is installed on the threaded rod, and a sleeve is fixedly connected to the outer side of one end of the extension plate, the sleeve is sleeved on the outer side of the positioning column, and a through hole matching the threaded rod is opened on the top surface.

The support component includes a threaded cylinder 13, a screw rod 14 is threadedly connected to the inner side of the threaded cylinder 13, and a pad 15 is fixed to the bottom of the screw rod 14.

[0020] By rotating the screw rod 14 through the foot 15, the depth of the screw rod 14 inserted into the threaded tube 13 can be adjusted, thereby achieving the adjustment of the height of the U-shaped frame 1; the conveyor belt 2 can realize the transportation of the plate.

[0021] like Figure 1 and Figure 3 As shown, fixed plates 3 are symmetrically fixed on both sides of the outside of the U-shaped frame 1, and a guide rail 4 is fixed on the top of the fixed plate 3. A movable frame 5 is provided above the U-shaped frame 1. The bottoms of both ends of the movable frame 5 are slidably connected to the guide rail 4 through a support seat 6. A limiting groove adapted to the guide rail 4 is opened on the support seat 6, and a roller is installed inside the limiting groove. A linear motor 16 for driving the movable frame 5 to move is installed on one side of the outside of the U-shaped frame 1, and a connecting plate 17 fixedly connected to the support seat 6 is installed on the moving subassembly of the linear motor 16.

[0022] The linear motor 16 drives the support base 6 to move through the connecting plate 17 , so that the movable frame 5 moves along the guide rail 4 , and the position of the movable frame 5 can be adjusted.

[0023] A cylinder 7 is installed at the top of the U-shaped frame 1, a horizontal plate 8 is installed at the output end of the cylinder 7, and a vacuum suction cup 9 is installed at the bottom of the horizontal plate 8.

[0024] The height of the horizontal plate 8 and the vacuum suction cup 9 can be adjusted by extending and retracting the cylinder 7, so as to facilitate the adsorption and lifting of the plate.

[0025] like Figure 2 and Figure 4As shown, a cylinder 2 10 is symmetrically installed at one end of the U-shaped frame 1, and a limit plate 11 is installed at the output end of the cylinder 2 10. An extension plate 12 is detachably connected to one end of the limit plate 11. The bottom surface of the limit plate 11 abuts against the top surface of the conveyor belt 2, and a folded edge is provided at one end of the limit plate 11 close to the movable frame 5. The two limit plates 11 are in an eight-shaped structure. A support block 18 is fixedly connected to the outer side of one end of the limit plate 11 close to the extension plate 12, and a positioning column 19 is fixedly connected to the top of the support block 18.
