Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a dust collection device suitable for ultra-large-format laser cutting machines. Background Art

[0002] Laser cutting technology is widely used in metal processing, aerospace, automobile manufacturing and other fields, especially ultra-large-format laser cutting machines, which can process large-sized and complex-shaped workpieces, significantly improving production efficiency and processing flexibility. Ultra-large-format laser cutting machines will generate a large amount of dust and smoke during high-speed cutting, which will not only endanger the health of workers, but may also cause wear and damage to the precision components of the equipment. At present, traditional cutting machines usually collect dust through fixed dust hoods. Although this treatment method reduces the harm of dust to equipment and personnel to a certain extent, the dust hood lacks flexibility and cannot move with the cutting workpiece. Therefore, it cannot cope well with dust that changes position during high-speed cutting. Some dust will be difficult to be absorbed in time, resulting in incomplete dust treatment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Traditional cutting machines usually collect dust through fixed dust hoods. Although this treatment method reduces the harm of dust to equipment and personnel to a certain extent, the dust hood lacks flexibility and cannot move with the cutting workpiece. Therefore, it cannot effectively cope with the dust that constantly changes position during high-speed cutting. Some dust will be difficult to be absorbed in time, resulting in incomplete dust treatment.

[0023] To solve the above defects in the dust collection process of the cutting machine, please refer to Figure 1-Figure 5The utility model provides a dust collection device suitable for an ultra-large-format laser cutting machine, which enables a dust collection vehicle 43 to follow the cutting piece 5 for mobile dust collection, and effectively absorbs the dust generated when the cutting piece 5 is cut in time, thereby improving the dust collection efficiency. The dust collection device is based on a frame 1, and a crossbeam 2 is installed on the top of the frame 1. Both ends of the crossbeam 2 are fixedly connected to light curtain brackets 3, and a dust collection mechanism 4 is provided between the two light curtain brackets 3. The dust collection mechanism 4 is used to absorb dust, and the dust collection mechanism 4 is set as a dust collection duct 41 fixedly installed between the two light curtain brackets 3. A sealing belt 42 is fixedly installed on one side of the dust collection duct 41, and a dust collection vehicle 43 is slidably installed on the outside of the sealing belt 42. A plurality of evenly distributed ventilation holes 46 are provided on the side of the dust collection duct 41, and the height of the ventilation holes 46 is less than the height of the sealing belt 42. A dust collection hole 44 is provided at the bottom of the dust collection vehicle 43, and the interior of the dust collection vehicle 43 A plurality of evenly distributed auxiliary rollers 45 are installed, and a sealing belt 42 is wound on the plurality of auxiliary rollers 45. The dust generated by cutting enters the dust collection vehicle 43 from the dust collection hole 44, and then enters the dust collection air duct 41 from the ventilation hole 46, and can then be discharged along the dust collection air duct 41. The sealing belt 42 can seal the plurality of ventilation holes 46 to prevent dust leakage. Due to the setting of the auxiliary rollers 45, when the dust collection vehicle 43 slides along the sealing belt 42, the ventilation holes 46 corresponding to the dust collection vehicle 43 can be opened, while the other ventilation holes 46 are blocked by the sealing belt 42, so that the dust can only enter the dust collection air duct 41 from the dust collection vehicle 43, thereby achieving the effect of mobile dust collection.

[0024] In actual use, the vacuum truck 43 needs to be able to move synchronously with the cutting position of the workpiece in order to achieve effective vacuuming. Therefore, a cutting piece 5 is slidably installed on the outside of the beam 2, and an electric slide rail is provided on the beam 2 for driving the cutting piece 5 to slide left and right. This is a prior art and will not be described in detail here. A connecting rod 6 is fixedly installed on the top of the cutting piece 5, and the end of the connecting rod 6 is fixedly installed on the vacuum truck 43. When the cutting piece 5 slides on the beam 2 to cut the workpiece, it can drive the connecting rod 6 to slide synchronously. The sliding of the connecting rod 6 can drive the vacuum truck 43 to slide, thereby realizing that the vacuum truck 43 follows the cutting piece 5 to slide synchronously. While the cutting piece 5 is performing the cutting operation, the vacuum truck 43 can absorb the dust generated during cutting in time to prevent the dust from spreading to the surrounding environment.

[0025] In order to absorb and collect dust, a vacuum cleaner 7 is provided on the side of the frame 1. The output end of the vacuum cleaner 7 is connected to a hose 8. The end of the hose 8 is connected to the dust suction duct 41 to drive the vacuum cleaner 7. The vacuum cleaner 7 can absorb the dust along the hose 8 and the dust suction mechanism 4. In addition, a chain track 9 is also installed on the side of the frame 1. A tank chain 10 is provided on the chain track 9. The hose 8 is installed on the edge of the tank chain 10, which not only enables the hose 8 to adapt to the sliding of the beam 2, but also enhances the stability of the hose 8.

[0026] Since large metal debris may be generated during cutting, if such debris is sucked into the hose 8 by the vacuum cleaner 7, it is very likely to cause blockage of the hose 8. In order to solve this technical problem, a protective net 47 is fixedly installed on the inner wall of the dust suction duct 41. The protective net 47 is adapted to the ventilation hole 46. The protective net 47 can intercept the metal debris and prevent the hose 8 from being blocked.

[0027] In order to prevent the protective net 47 from being clogged by metal debris and dust, brushes 48 are symmetrically installed inside the vacuum truck 43. The sides of the brushes 48 are in contact with the protective net 47. When the vacuum truck 43 follows the cutting piece 5 to slide and vacuum, it can drive the brushes 48 to slide. The sliding of the brushes 48 can clean the protective net 47 and sweep away impurities attached to the protective net 47, which can effectively prevent the protective net 47 from being clogged.

[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0029] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
