Technical Field

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

[0002] Laser cutting machine is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. As the relative position of the beam and the workpiece moves, the material is finally cut to achieve the purpose of cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment. The mechanical part of the laser cutter head does not contact the workpiece and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat-affected zone is small, the plate deformation is small, and the cutting seam is narrow; the incision has no mechanical stress and no shear burrs; the processing precision is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plane diagram, and can cut a large whole plate without opening a mold, which is economical and time-saving.

[0003] At present, in the process of using laser to cut cloth, as the cloth cutting seam is formed, the cut cloth will warp and curl at the cutting seam due to various factors such as stress, which will affect the subsequent cutting of the cloth and the cutting accuracy. At the same time, dust will produce a lot of smoke in the process of cloth cutting, causing air pollution. For this reason, we propose a new type of laser cutting machine. Utility Model Content

It solves the problem that in the current process of using laser to cut cloth, as the cloth cutting seam is formed, the cut cloth will warp and curl at the cutting seam due to various factors such as stress, affecting the subsequent continued cutting of the cloth and the cutting accuracy. At the same time, dust in the process of cloth cutting generates a large amount of smoke, causing air pollution.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model achieves the effect of avoiding warping and curling of cloth during laser cutting by arranging a fixing frame, a screw rod, a threaded slider, a laser cutting head, a suction hood, an electric push rod, a lifting tube, a cross plate, an exhaust fan and a smoke purifier, thereby improving the cutting accuracy and absorbing and purifying the smoke generated during the cutting process to avoid air pollution.

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 3 As shown, a new type of laser cutting machine proposed by the utility model includes a fixing frame 1, a smoke purifier 2 and an exhaust fan 3. The fixing frame 1 runs through the front and back, and a screw rod 13 is rotatably installed on the top of the inner wall of the fixing frame 1. A rotating motor 9 is fixedly installed on one side of the outer surface of the fixing frame 1. The end of the output shaft of the rotating motor 9 is fixedly connected to the end of the screw rod 13. A threaded block 15 is movably sleeved on the outer surface of the screw rod 13. The threads on the inner wall of the threaded block 15 are meshed with the threads on the outer surface of the screw rod 13. The top of the inner wall of the fixing frame 1 is fixedly installed near the front surface and the rear surface of the threaded block 15. A limit plate 14 is installed, and the two limit plates 14 play a role of limiting the thread block 15 to prevent the thread block 15 from rotating. A laser cutting head 16 is fixedly installed on the lower surface of the thread block 15, and an electric push rod 4 is fixedly installed at the middle position of the upper surface of the fixed frame 1. The end of the electric push rod 4 is fixedly connected to a cross plate 5, and both ends of the cross plate 5 are fixedly connected to lifting tubes 12. One end of the two lifting tubes 12 located inside the fixed frame 1 is fixedly connected to a suction hood 11. The two suction hoods 11 are long flat plates with a hollow interior, and suction ports are provided on the opposite sides of the two suction hoods 11.

[0021] A branch pipe 6 is fixedly connected to the end of the input pipe of the exhaust fan 3, and both ends of the branch pipe 6 are respectively fixedly connected to the ends of the two lifting pipes 12, the input end of the smoke purifier 2 and the end of the output pipe of the exhaust fan 3 are fixedly connected, and a smooth plate 10 is fixedly installed on the bottom of the inner wall of the fixed frame 1 to prevent the cloth from being worn due to friction between the cloth and the bottom of the inner wall of the fixed frame 1 when the cloth passes through the fixed frame 1. Slide rods 7 are symmetrically fixedly connected at both sides of the upper surface of the two suction hoods 11. Through holes 8 are symmetrically provided at both sides of the upper surface of the fixed frame 1 above the two suction hoods 11, and four slide rods 7 pass through the four through holes 8 respectively, so that when the suction hood 11 is lifted or lowered, the slide rod 7 is lifted or lowered accordingly, thereby improving the stability of the suction hood 11.

[0022] When the utility model is in use, the cloth passes through the fixed frame 1 and is located below the laser cutting head 16. The electric push rod 4 drives the cross plate 5, the lifting tube 12 and the suction hood 11 to descend. The two suction hoods 11 press the cloth tightly. The screw rod 13 rotates and drives the laser cutting head 16 to move through the threaded block 15 to complete the cutting of the cloth. In the process of cutting, the two suction hoods 11 press and fix the cloth on both sides of the cutting seam, thereby avoiding the occurrence of warping and curling of the cloth. At the same time, the exhaust fan 3 works so that the smoke generated during the cutting process is sucked in from the suction hood 11 and discharged into the smoke purifier 2 for purification, thereby avoiding air pollution.
