Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to a dust removal mechanism for a laser cutting machine. 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. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. The laser cutting machine processing method has the characteristics of high precision and low processing cost.

[0003] When existing laser cutting machines are used to process parts, smoke, debris, welding slag, etc. will be generated. In order to ensure the cleanliness of the workbench surface, laser cutting machines are generally equipped with corresponding dust suction mechanisms to achieve dust removal. However, most of the existing dust suction mechanisms are in a fixed state. When encountering larger-scale cutting work, due to the large lateral movement distance of the laser transmitter, the fixed dust suction mechanism cannot effectively absorb the smoke and dust from a long distance, resulting in limited dust removal effect. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a dust removal mechanism for a laser cutting machine, which can realize that the dust collection mechanism and the laser transmitter move together to ensure the dust removal effect.

[0007] Furthermore, an extension shaft is symmetrically arranged at both ends of the adjusting suction cylinder, a docking rod is rotatably mounted on the surface of the extension shaft, and a locking bolt is screwed on the surface of one side of the docking rod close to the adjusting suction cylinder.

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1-Figure 4 As shown, a dust removal mechanism of a laser cutting machine includes a support frame 1 and an adjustment suction cylinder 12. Conveying rollers 2 are evenly arranged on the inner side of the support frame 1. Multiple conveying rollers 2 are pushed synchronously. The cutting material is placed on the upper surface of multiple conveying rollers 2 to drive the cutting material to load. Columns 3 are symmetrically arranged on the upper surface of the support frame 1. The columns 3 and the support frame 1 are in a fixed state. A slide groove 31 is vertically opened on the inner side of the column 3. A lifting block 5 is vertically slidably installed inside the slide groove 31. A control hydraulic cylinder 4 is fixed on the top of the column 3. The output end of the control hydraulic cylinder 4 is installed on the upper surface of the lifting block 5. Threaded rods 6 and track rods 7 are respectively installed between the two lifting blocks 5 through bearings. Moving boxes 8 are slidably installed on the surfaces of the threaded rods 6 and the track rods 7. The hydraulic cylinder 4 controls the height of the moving box 8, and then controls the height of the laser emitter 9 to adapt to the cutting of materials of different thicknesses. The laser emitter 9 is fixed at the bottom of the moving box 8, and a vacuum cleaner 10 is fixed at the top of the moving box 8. A dust collecting box 11 is detachably installed on the top of the vacuum cleaner 10. The adjusting suction cylinder 12 is placed at the lower front side of the moving box 8. A notch groove 121 is provided on the side of the adjusting suction cylinder 12 close to the laser emitter 9. A connecting hose 13 is connected to the top of the adjusting suction cylinder 12. The end of the connecting hose 13 facing away from the adjusting suction cylinder 12 is connected to the vacuum cleaner 10. The vacuum cleaner 10 is started to absorb the gas inside the adjusting suction cylinder 12 through the connecting hose 13, so that a negative pressure is formed inside the adjusting suction cylinder 12 to absorb the smoke during cutting.

[0021] Please refer to Figure 1-Figure 4 As shown, the two ends of the adjustment suction cylinder 12 are centrally symmetrically provided with extension shafts 122, and a docking rod 15 is rotatably installed on the surface of the extension shaft 122. A locking bolt 151 is screwed on the surface of the docking rod 15 close to the adjustment suction cylinder 12. The adjustment suction cylinder 12 can be rotated to adjust the direction of the notch groove 121 to ensure that the notch groove 121 is facing the cutting position and is fixed by the locking bolt 151.

[0022] Among them, swing rods 14 are symmetrically installed on both sides of the moving box 8 through pin shafts, and the end of the docking rod 15 facing away from the adjusting suction cylinder 12 is placed inside the swing rod 14. A locking bolt 141 is screwed on the outer side of the end of the swing rod 14. The docking rod 15 is fixed by the locking bolt 141 to adjust the distance between the adjusting suction cylinder 12 and the moving box 8, and is fixed by the locking bolt 141.

[0023] Please refer to Figure 2 and Figure 3As shown, arc frames 16 are symmetrically arranged on both sides of the support frame 1, and the arc frames 16 are placed on the outside of the swing rod 14. A track groove 17 is opened on the surface of the arc frame 16, and the track groove 17 is concentric with the rotation axis of the swing rod 14. A locking plate 18 is screwed on the surface of the swing rod 14, and the locking plate 18 passes through the track groove 17. When the locking plate 18 is rotated to release, the swing rod 14 can be rotated around its installation axis. Conversely, it can be fixed by the locking plate 18 after the position adjustment is completed.

[0024] The working principle of the utility model is as follows: the material to be cut is placed on the upper surface of the conveying roller 2, and the material is driven to move by the rotation of multiple conveying rollers 2 to realize the feeding work, and the height of the lifting block 5 is controlled by controlling the hydraulic cylinder 4, and then the distance between the laser emitter 9 and the material passing below is controlled, and the threaded rod 6 is driven by the motor to move, so as to drive the moving box 8 to slide along the axis of the threaded rod 6, and then horizontal cutting is realized. When in use, the vacuum cleaner 10 is started to realize the vacuuming work, and the debris and dust during cutting will enter the adjustment suction cylinder through the notch groove 121 12, and transported to the inside of the vacuum cleaner 10 through the connecting hose 13, so as to be centralized for processing. At the same time, the relative positions of the suction cylinders 12 can be adjusted, and the swing rod 14 can be rotated to control its angle. The locking plate 18 and the track groove 17 cooperate with each other to keep the angle of the swing rod 14 stable. At the same time, the relative distance between the docking rod 15 and the swing rod 14 can be adjusted, and they can be fixed by the locking bolt 141. The rotation of the suction cylinder 12 can be adjusted to control the direction of the notch groove 121, to ensure that the notch groove 121 corresponds to the laser cutting position, and to ensure the dust removal effect.

[0025] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
