Description

Technical Field

[0001] This utility model belongs to the field of laser cutting dust removal technology, specifically relating to a dust removal device for laser cutting machines. Background Technology

[0002] Laser cutting machines use invisible light beams instead of traditional mechanical blades, and are gradually improving or replacing traditional metal cutting equipment. During laser cutting, smoke, dust, and exhaust gases are generated. These substances contain harmful materials and need to be treated by dust removal devices.

[0003] Chinese patent application CN202323004443.1 discloses a dust removal device for laser cutting machines, belonging to the field of laser cutting dust removal technology. It includes a filter mechanism with casters fixedly installed at the four corners of the bottom of the filter mechanism. A fan is fixedly installed on one side of the top of the filter mechanism. Multiple filter plates are arranged inside the filter mechanism. A clamping mechanism is located at the center of the filter mechanism on the side away from the fan. The clamping mechanism includes a mounting plate, and movable rods are slidably installed at the center of both sides of the mounting plate. This dust removal device for laser cutting machines, by setting up a clamping mechanism and a connecting pipe, widens the distance between two sets of clamping rings by pulling two sets of pull plates. After the connecting air pipe is placed between the two sets of clamping rings, releasing the two sets of pull plates causes the distance between the two sets of clamping rings to narrow under the spring's return action, clamping the connecting air pipe inside the clamping mechanism, facilitating the disassembly or installation of the connecting air pipe.

[0004] 1. The aforementioned patent has the problem that the position of the connecting air pipe cannot be changed. Laser cutting requires machine tool operation. If the dust suction port cannot be fixed at the cutting position, it will result in incomplete dust suction. 2. The aforementioned patent has the problem that the height of the filter box cannot be changed. Since the height of the cutting machine tool is inconsistent, the inability to change the height will reduce its practicality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a dust removal device for a laser cutting machine, comprising a filter box 1, a fixing mechanism 2 on one side of the filter box 1, a filter plate 3 on the inner side of the filter box 1, a base plate 5 fixedly connected to the bottom of the filter box 1, a fan 4 on the side of the filter box 1 away from the fixing mechanism 2, a lifting mechanism 6 on one side of the base plate 5, a support plate 7 at the lower end of the side of the lifting mechanism 6, a support column 8 at the bottom of the support plate 7, and a moving wheel 9 at the bottom of the support column 8.

[0024] Specifically, the fixing mechanism 2 includes a hose 21, a gasket 22, an L-shaped plate 23, a suction cup 24, and an adsorption assembly 25. The gasket 22 is provided on the side of the hose 21 near the filter box 1, and the L-shaped plate 23 is provided at the end of the hose 21 away from the filter box 1. The suction cup 24 is fixedly connected to the outer side of the L-shaped plate 23, and the adsorption assembly 25 is provided on the inner side of the L-shaped plate 23.

[0025] By adopting the above technical solution, the hose 21 can be arbitrarily contracted, making it convenient to stretch the hose 21 to place the L-shaped plate 23 on the plane where the cutting work is located. After the suction end of the hose 21 is aligned with the cutting platform, the L-shaped plate 23 is further fixed by the suction cup 24 on one side of the L-shaped plate 23. The gasket 22 can strengthen the connection between the filter box 1 and the hose 21 to prevent dust from overflowing. The adsorption component 25 can absorb the smoke and odor generated during the suction of the hose 21.

[0026] Specifically, the adsorption assembly 25 includes an adsorption box 251, a chute 252, an air vent 253, a perforated plate 254, and activated carbon balls 255. The bottom of the adsorption box 251 is provided with an air vent 253, the inner side of the adsorption box 251 is provided with a chute 252, the inner side of the chute 252 is provided with a perforated plate 254, and the top of the perforated plate 254 is fixedly connected to the activated carbon balls 255.

[0027] By adopting the above technical solution, the perforated plate 254 on the inner side of the adsorption box 251 can be removed along the slide 252 to replace the activated carbon ball 255. When the fan 4 is started, the smoke and dust enter the adsorption box 251 through the air hole 253 at the bottom of the adsorption box 251. At the same time, small dust particles and gases will be adsorbed by the activated carbon ball 255, which can enhance the dust collection effect and remove odors.

[0028] Specifically, an iron block 26 is fixedly connected to the side of the hose 21 near the L-shaped plate 23, and a magnet 27 is provided on the side of the filter box 1 away from the gasket 22.

[0029] By adopting the above technical solution, when the hose 21 is not used for vacuuming, the hose 21 can be retracted and the iron block 26 can be attracted to the magnet 27 for storage.

[0030] In this embodiment, the fan 4 is connected to an external power source. The support plate 7 can be moved freely via the support column 8 and the casters 9. After adjusting the height of the base plate 5 and the filter box 1 via the lifting mechanism 6, the fan 4 can be started to draw the cutting dust into the filter box 1 and filter it through the filter plate 3. The hose 21 can be retracted at will, making it easy to extend the hose 21 to place the L-shaped plate 23 on the plane where the cutting work is located. After the suction end of the hose 21 is aligned with the cutting platform, the L-shaped plate 23 is further fixed by the suction cup 24 on one side of the L-shaped plate 23. The gasket 22 can reinforce the filter box 1 and the hose. The connection of 21 prevents dust from overflowing. The perforated plate 254 on the inside of the adsorption box 251 can be removed along the slide 252 to replace the activated carbon ball 255. When the fan 4 is started, the smoke and dust enter the adsorption box 251 through the air hole 253 at the bottom of the adsorption box 251. At the same time, small dust particles and gas will be adsorbed by the activated carbon ball 255, which can enhance the dust collection effect and remove odors. When the hose 21 is not used for dust collection, the hose 21 can be retracted and the iron block 26 can be attracted to the magnet 27 for storage. The hose 21 can be fixed by the L-shaped plate 23, which can change the dust collection position and improve the dust collection efficiency.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the lifting mechanism 6 includes a fixed frame 61, a motor 62, a lead screw 63, a connecting plate 64, and a guide rod 65. The motor 62 is fixedly connected to the bottom of the fixed frame 61, the lead screw 63 is provided on the rotating shaft of the motor 62, the connecting plate 64 is provided on the outer side of the lead screw 63, the outer side of the connecting plate 64 is fixedly connected to the bottom plate 5, and the guide rod 65 is fixedly connected to the inner side of the fixed frame 61 away from the lead screw 63.

[0033] By adopting the above technical solution, the fixed frame 61 is fixedly connected to the support plate 7, and the connecting plate 64 has a nut seat inside. When the motor 62 drives the lead screw 63 to rotate, the connecting plate 64 can move up and down along the lead screw 63. The connecting plate 64 is fixedly connected to the base plate 5, so when the connecting plate 64 moves up and down, it will drive the base plate 5 to rise and fall, changing the suction height.

[0034] Specifically, a buffer pad 66 is fixedly connected to the bottom of the base plate 5 on the side away from the fixing frame 61.

[0035] By adopting the above technical solution, the buffer pad 66 can reduce pressure and maintain stability when the base plate 5 descends.

[0036] In this embodiment, the motor 62 is connected to an external power source, the fixing frame 61 is fixedly connected to the support plate 7, and the connecting plate 64 has a nut seat inside. When the motor 62 drives the lead screw 63 to rotate, the connecting plate 64 can move up and down along the lead screw 63. The connecting plate 64 is fixedly connected to the base plate 5, so when the connecting plate 64 moves up and down, it will drive the base plate 5 to rise and fall, changing the suction height. The buffer pad 66 can reduce the pressure when the base plate 5 descends and keep it stable. By driving the lead screw 63 to rotate through the motor 62, the suction height can be changed, improving practicality.

[0037] The structure and operating principle of the filter box 1, filter plate 3, fan 4, support column 8 and moving wheel 9 in this utility model have been disclosed in a dust removal device for a laser cutting machine disclosed in Chinese patent application number CN202323004443.1.

[0038] The working principle and usage process of this utility model are as follows: When using this utility model, the fan 4 is connected to an external power source. The support plate 7 can be moved arbitrarily through the support column 8 and the moving wheel 9. After adjusting the height of the base plate 5 and the filter box 1 through the lifting mechanism 6, the fan 4 can be started to suck the dust generated during cutting into the filter box 1 and filter it through the filter plate 3. The hose 21 can be retracted arbitrarily, making it convenient to extend the hose 21 to place the L-shaped plate 23 on the plane where the cutting work is located. After the suction end of the hose 21 is aligned with the cutting platform, the L-shaped plate 23 is further fixed by the suction cup 24 on one side of the L-shaped plate 23. The gasket 22 can strengthen the connection between the filter box 1 and the hose 21 to prevent dust from overflowing. The perforated plate 254 on the inner side of the adsorption box 251 can be removed along the slide groove 252 to replace the activated carbon ball 255. When the fan 4 is started, the dust flows along the air hole 253 at the bottom of the adsorption box 251. Upon entering the adsorption box 251, small dust particles and gases are adsorbed by the activated carbon balls 255, enhancing the dust collection effect while also removing odors. When not using the hose 21, it can be retracted, and the iron block 26 can be adsorbed onto the magnet 27 for storage. The hose 21 can be fixed by the L-shaped plate 23, which can change the dust collection position and improve dust collection efficiency. The motor 62 is connected to an external power source, and the fixing frame 61 is fixedly connected to the support plate 7. The connecting plate 64 has a nut seat inside. When the motor 62 drives the lead screw 63 to rotate, the connecting plate 64 can move up and down along the lead screw 63. The connecting plate 64 is fixedly connected to the base plate 5, so when the connecting plate 64 moves up and down, it will drive the base plate 5 to rise and fall, changing the dust collection height. The buffer pad 66 can reduce pressure when the base plate 5 descends and maintain stability. By driving the lead screw 63 to rotate by the motor 62, the dust collection height can be changed, improving practicality.
