Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figures 1 to 9 This embodiment provides a turbocharged dust removal device for a laser cutting machine, including a laser cutter 1, a translation mechanism 2, a turbocharger unit 3, a jet head 4, and an adsorption component 5.

[0019] The laser cutter 1 is fixed to the translation mechanism 2, the turbocharger unit 3 is fixed to one side of the laser cutter 1, and the jet head 4 is fixed to the laser cutter 1 and connected to the turbocharger unit 3 via a pipe. The translation mechanism 2 can be an existing one, generally capable of translation within the x and y axis planes, thereby moving the laser cutter 1 to complete the laser cutting of the material. The turbocharger unit 3 uses an existing turbine fan, which generates airflow to the jet head 4, blowing the dust generated during laser cutting towards the adsorption assembly 5.

[0020] The adsorption assembly 5 is fixed to the side of the laser cutter 1 away from the jet head 4. The adsorption assembly 5 includes an adsorption shell 5a, a magnetic block 5b, and a rotating shaft 5c. The adsorption shell 5a is hollow and fixed to the lower end of the laser cutter 1. The rotating shaft 5c passes through the adsorption shell 5a, and the lower end of the adsorption shell 5a forms an adsorption surface 5aa. Both ends are rotatably connected to the adsorption shell 5a. The magnetic block 5b is disposed inside the adsorption shell 5a and is fixedly connected to the rotating shaft 5c. The rotating shaft 5c rotatably drives the magnetic block 5b to move, and the magnetic block 5b has at least an adsorption position close to the adsorption surface 5aa and a release position away from the adsorption surface 5aa. The adsorption shell 5a is made without magnetic... The magnetic block 5b is typically made of permanent magnets, such as neodymium iron boron magnets. When the magnetic block 5b is in the adsorption position, it is close to the adsorption surface 5aa. Through magnetization of the adsorption shell 5a, or by the magnetic force of the magnetic block 5b itself, it attracts magnetically adsorbable metals such as iron from the dust blown near the magnetic block 5b by the jet head 4. A large amount of dust is adsorbed onto the adsorption surface 5aa. When the rotating shaft 5c is rotated to move the magnetic block 5b to the release position, the magnetic block 5b moves away from the adsorption surface 5aa, the adsorption shell 5a loses its magnetic force, or the metal dust on the adsorption surface 5aa loses the attraction of the magnetic block 5b, thus falling off the adsorption surface 5aa. Preferably, the turbocharged dust removal device for the laser cutting machine also includes a drive unit, which can be a cylinder, motor, etc., to drive the rotating shaft 5c to rotate.

[0021] Preferably, the adsorption assembly 5 further includes a mounting plate 5d, and a magnetic block 5b is fixed to the mounting plate 5d. The magnetic block 5b and the mounting plate 5d can be connected by means of adhesive adhesion or other methods. The mounting plate 5d has a first mating hole 5da, and the rotating shaft 5c forms a mating part 5ca along the axial direction. The mating part 5ca extends at least to one end to form a connecting part 5cb. The mating part 5ca is engaged with the first mating hole 5da to restrict relative rotation between the two. More preferably, the first mating hole 5da and the mating part 5ca have hexagonal cross-sections.

[0022] Preferably, the adsorption assembly 5 further includes a connecting sleeve 5e, which has a second mating hole 5ea. The second mating hole 5ea is mated with the mating part 5ca. The end face of the connecting sleeve 5e abuts against the side of the mounting plate 5d. The adsorption shell 5a has a mounting hole 5ab. The outer side of the connecting sleeve 5e is rotatably connected to the mounting hole 5ab. The connecting sleeve 5e and the mounting hole 5ab can be rotatably connected by a bearing. More preferably, the adsorption assembly 5 further includes a first connecting nut 5f. The first connecting nut 5f is disposed on the side of the connecting sleeve 5e away from the mounting plate 5d and is threadedly connected to the connecting part 5cb. The first connecting nut 5f is used to fix the connecting sleeve 5e.

[0023] Preferably, the adsorption assembly 5 further includes a drive handle 5g, which is located on the side of the first connecting nut 5f away from the connecting sleeve 5e. The drive handle 5g includes a handle portion 5ga and a rotating portion 5gb, which are fixedly connected. The rotating portion 5gb is connected to the connecting portion 5cb via a keyway, allowing the magnetic block 5b to be rotated manually by rotating the drive handle 5g. More preferably, the adsorption assembly 5 further includes a second connecting nut 5h, which is located on the side of the drive handle 5g away from the first connecting nut 5f and is threadedly connected to the connecting portion 5cb. The second connecting nut 5h is used to fix the drive handle 5g.

[0024] Preferably, the turbocharged dust removal device for the laser cutting machine further includes a frame 6 and a drive rod 7. The translation mechanism 2 is fixed to the frame 6, and the drive rod 7 is fixed to the frame 6. When the cutter is moved by the translation mechanism 2, the drive rod 7 can abut against the drive handle 5g, further causing the drive handle 5g to rotate. Therefore, the drive rod 7 can be installed near the origin of the translation mechanism 2. After each laser cutting is completed, the translation mechanism 2 returns to the origin. During this process, the drive rod 7 remains stationary, while the drive handle 5g moves towards the position close to the drive rod 7. The drive handle 5g is pushed and rotated by the drive rod 7, thereby causing the magnetic block 5b to rotate to the release position. When the drive handle 5g disengages from the drive rod 7, the magnetic block 5b will rotate to the adsorption position due to its own weight. More preferably, the turbocharged dust removal device for the laser cutting machine also includes a waste box 8. The waste box 8 is located below the drive rod 7 and is detachably connected to the frame 6. The waste box 8 can collect iron powder and other metals released from the adsorption surface 5aa. It should be noted that two connecting parts 5cb can be respectively set at both ends of the mating part 5ca. The connecting sleeve 5e, the first connecting nut 5f, the drive handle 5g, the second connecting nut 5h, and the drive rod 7 can all be set with two sets corresponding to the two connecting parts 5cb respectively.

[0025] Preferably, the adsorption assembly 5 further includes a torsion spring 5i, which is sleeved on the rotating shaft 5c and its two ends abut against the inner side of the adsorption shell 5a and the magnetic block 5b, respectively. The torsion spring 5i is used to drive the magnetic block 5b to rotate from the release station to the adsorption station to prevent the magnetic block 5b from failing to reset due to accident.

[0026] In summary, the present invention provides a turbocharged dust removal device for a laser cutting machine. The turbocharger unit 3 and the jet head 4 generate airflow, which concentrates dust and debris and blows them to one side, effectively reducing the impact on laser beam cutting. The rotating shaft 5c can drive the magnetic block 5b to switch between the adsorption station and the release station. When the magnetic block 5b is in the adsorption station, it can magnetically adsorb metal dust and debris near the adsorption surface 5aa, preventing the adsorbed material from affecting the laser cutting operation. When it is necessary to release the adsorbed material, the magnetic block 5b rotates to the release station, and the metal dust and debris adsorbed by the adsorption surface 5aa are detached from the adsorption surface 5aa, thereby realizing the separation of metal objects.
