Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and particularly relates to a dust removal equipment for laser cutting. Background Art

[0002] Laser cutting equipment mainly irradiates laser onto the raw materials to be cut through a laser head, and melts or vaporizes the materials on the raw materials through the high temperature of the laser. During the cutting process, a large amount of dust and smoke will be generated. If not cleaned in time, it will not only have an adverse impact on the equipment and reduce the service life of the equipment, but also workers are prone to respiratory diseases if they breathe polluted air for a long time. Therefore, generally, high-power laser cutting equipment will be equipped with a ventilation and dust collection device to extract and remove the waste gas containing dust, smoke, etc. generated during its cutting.

[0003] At present, in order to prevent the use of the cutting machine, the suction hood of the ventilation and dust collection device is made too small, which results in some dust still being unable to be sucked and thus floating into the air, resulting in poor dust collection effect. However, the simplest way to ensure the dust collection effect is to increase the size of the suction hood and reduce the distance between the suction hood and the cutting machine. However, such a design will undoubtedly cause a certain blockage to the cutting machine and have a certain impact on the cutting work. Therefore, how to ensure that the suction hood has a sufficient dust collection size while ensuring that it will not have too much impact on the cutting work is an urgent problem to be solved by those skilled in the art.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides an embodiment of a dust removal device for laser cutting as shown in Figures 1 to 4 : It includes a bracket 1 and a dust suction hood 2. The bracket 1 is located outside the dust suction hood 2 and the laser cutting machine 12 and is fixed on the ground. The dust suction hood 2 is arranged directly above the laser cutting machine 12. The dust suction port of the dust suction hood 2 faces downward, and the dust suction hood 2 covers the laser cutting machine 12 through its dust suction port, which can effectively prevent dust from spreading to the outside. A flexible dust suction pipe 201 is provided on the upper part of the dust suction hood 2, and the dust suction pipe 201 is connected to an external dust suction device. An observation window is provided on the outer surface of the dust suction hood 2, and the observation window is made of a transparent material to facilitate the operator to observe the internal cutting and processing situation. A sliding plate 3 is slidably installed on the outside of the bracket 1. A connecting shaft 6 is provided on the outer surface of the sliding plate 3, and the sliding plate 3 is rotatably connected to the dust suction hood 2 through the connecting shaft 6. A linear driving device 4 is installed on the bracket 1 for driving the sliding plate 3 to slide vertically. The linear driving device 4 is a cylinder, and the cylinder is arranged vertically. The piston rod of the cylinder is connected to the sliding plate 3. A linear guiding device 5 is provided on the bracket 1. The linear guiding device 5 includes a linear guide rail and a slider. The linear guide rail is fixedly installed on the outer surface of the bracket 1 vertically, and the slider is slidably installed on the linear guide rail and is connected to the sliding plate 3 for guiding the up and down sliding of the sliding plate 3 and ensuring the stability of the sliding of the sliding plate 3. A rotating shaft 7 is rotatably installed on the sliding plate 3. A winding disc 8 is fixedly installed on the outer surface of the rotating shaft 7. A rope 9 is wound around the winding disc 8. One end of the rope 9 away from the winding disc 8 is connected to the dust suction hood 2. A gear 10 is installed at the end of the rotating shaft 7, and a rack 11 meshing with the gear 10 is fixedly installed on the outer surface of the bracket 1. The rack 11 is arranged vertically.

[0023] When the laser cutting machine 12 performs cutting processing, the dust suction hood 2 covering the laser cutting machine 12 can effectively prevent dust from spreading to the outside, thereby ensuring the cleanliness of the processing environment and the safety of the operator. Moreover, when the laser cutting machine 12 needs to be operated, the cylinder is started. At this time, the piston rod of the cylinder slides upward and pushes the sliding plate 3 and the dust suction hood 2 to slide upward. At the same time, the rotating shaft 7 also slides upward synchronously. During this process, the rack 11 can drive the rising rotating shaft 7 to rotate on the sliding plate 3 through the rack 11, thereby driving the wire winding disc 8 to rotate and continuing to wind the rope 9 on the wire winding disc 8. At this time, the end of the rope 9 away from the wire winding disc 8 will pull the dust suction hood 2, causing the dust suction hood 2 to rotate upward on the sliding plate 3 around the axis of the connecting shaft 6. Therefore, while driving the dust suction hood 2 to slide upward, it will also drive the dust suction hood 2 to flip backward and upward to open the upper part of the laser cutting machine 12, and the opened space is large. Therefore, even when the size of the dust suction hood 2 is designed to be large enough, it can prevent the dust suction hood 2 from affecting the operation of the laser cutting machine 12 and ensure the normal progress of the cutting work.

[0024] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
