Description

Technical Field

[0001] The utility model relates to an automatic collection device for laser cutting waste, belonging to the technical field of laser cutting waste collection. Background Art

[0002] Laser cutting machines for metal processing have become the main means of modern processing enterprises. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece.

[0003] During the laser cutting process, the cut waste and residue will fall into the collection device through the hollow grille on the workbench, and large pieces of waste will often be stacked on the upper end between two adjacent pieces and cannot fall down automatically, making them impossible to collect. Manual intervention is required to remove the large pieces of material, which is more troublesome. Existing laser cutting machines are also equipped with devices for clamping large pieces of material. However, the removal is still not thorough, and the removal efficiency is low, which is more troublesome.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0005] In response to the deficiencies in the background technology, the utility model provides an automatic collection device for laser cutting waste, which can discharge large pieces of material on the grid platform of the laser cutting machine by tilting and dumping. The operation is simple and easy, and the cleaning efficiency is high. The waste can also be automatically collected at one end of the laser cutting machine.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: an automatic collection device for laser cutting waste, comprising a laser cutting machine body, wherein two grid platforms are arranged side by side on the inner side of the laser cutting machine body, and the outer sides of the two grid platforms facing each other are respectively hinged to the inner side of the laser cutting machine body;

[0007] There are cylinders at the lower ends of the two grid platforms. When the telescopic rods of the cylinders are extended, they push and support the two grid platforms in a horizontal state, at which time normal laser cutting is performed. When the telescopic rods of the cylinders are retracted, they pull the two grid platforms downward, and the large pieces of waste on the grid platforms slide off.

[0008] Furthermore, a cylinder is provided on each side of the grid platform, and the lower end of the cylinder is hinged to the inner side of the laser cutting machine body.

[0009] Furthermore, a sliding groove is provided at each end of the grid platform along its width direction, a roller is rotatably installed in each sliding groove, and the rotating shaft of the roller is hinged to the telescopic rod of the cylinder.

[0010] Furthermore, a top plate is correspondingly provided at the lower end between every two adjacent grilles of the grille platform, so that the top plate is arranged in one-to-one correspondence with the gap between the adjacent grilles, and the upper end of the top plate includes a downwardly inclined slope.

[0011] Furthermore, when the cylinder contracts and the grille platform tilts downward, the inclined surface on the upper end of the top plate is inserted into the gap between two adjacent grilles of the grille platform, and the top plate is exactly located in the middle of the gap between the adjacent grilles.

[0012] Furthermore, a row of top plates is correspondingly provided at the lower end of each grid platform, and each row of top plates is individually and parallelly fixed on the inner side surface of the laser cutting machine body.

[0013] Furthermore, a row of top panels is correspondingly provided at the lower end of each grid platform, and the rear end of each row of top panels is fixed to a back panel.

[0014] Furthermore, a waste tray is provided at the lower end of the laser cutting machine body, and the waste tray is located at the lower end of the top plate.

[0015] Furthermore, the two ends of the waste tray are tilted with a certain height difference, and rotating shafts are fixed on both sides of the higher end of the waste tray, and the rotating shafts are rotatably installed on both sides of the laser cutting machine body. A driving shaft is rotatably installed on the lower side of the lower end of the waste tray, and a plurality of cams are fixed on the driving shaft.

[0016] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:

[0017] 1. The facing outer sides of the two grid platforms are respectively hinged to the inner side of the laser cutting machine body. When the telescopic rod of the cylinder contracts, the two grid platforms are pulled downward. At this time, the inclined surface of the upper end of the top plate is inserted into the gap between the two adjacent grids of the grid platform, and the top plate is exactly located in the middle of the gap between the adjacent grids. The top plate pushes the waste away from the grid platform, causing the waste to slide down, thereby preventing large pieces of waste from being supported on the grid of the grid platform. The operation is simple and easy, and the removal efficiency is high.

[0018] 2. A drive shaft is rotatably installed on the lower side of the lower end of the waste tray. A plurality of cams are fixed on the drive shaft. Driven by the motor, the cam drives the lower end of the waste tray to vibrate up and down, causing the waste in the waste tray to slide out, thereby realizing automatic unloading.
