[0005] In summary, we propose a zoned dust removal device for laser cutting machines to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a zoned dust removal device for laser cutting machines. By using this device, the problem of easy pollution of the workshop environment in the above-mentioned background art can be solved.

[0010] Preferably, an opening is provided on the side wall of the protective shell on one side of the center console, and a door panel is slidably connected inside the opening, with an observation window provided on the door panel.

[0011] Preferably, the air inlet has a rectangular structure and the air outlet has a circular structure.

[0012] Preferably, the opening and closing assembly includes a first base plate with a rectangular structure. The first base plate is fixedly connected to the air inlet on the inner wall of the bed.

Two first guide rails are installed at the middle of the upper and lower ends of the first base plate away from the air inlet. A first displacement plate is slidably connected between the two first guide rails. A first cylinder is installed on one side of the two first guide rails. The output end of the first cylinder is fixedly connected to the first displacement plate. A plurality of first ventilation slots with rectangular structures are evenly distributed on the first base plate between the two first guide rails. The first ventilation slots are connected to the air inlet. The first displacement plate is evenly distributed with the same number of first through slots as the number of first ventilation slots, and the first through slots penetrate the first displacement plate. The distance between adjacent first through slots is greater than the width of the first ventilation slots and less than the distance between adjacent first ventilation slots.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Improve the workshop working environment: The operation of the fan creates negative pressure in the flow chamber inside the bed. With the help of the adjustable fan, the smoke and dust are guided in a specific direction. The air inlet, controlled by the corresponding opening and closing components, draws the pollutants into the flow chamber. Finally, the fan discharges the pollutants to the external purification equipment through the duct. This achieves efficient collection and discharge of smoke and dust generated during cutting, preventing pollutants from spreading into the workshop air, improving the working environment, and reducing the threat to the respiratory health of operators.

[0015] 2. Protect internal components: The zoned opening and closing mechanism only opens the air inlet of the working area. Combined with the fan, smoke and dust are precisely guided to the air inlet, reducing the residence and accumulation of pollutants inside the protective shell and the processing chamber of the machine bed. This effectively protects the optical components and mechanical parts inside the laser cutting machine and reduces equipment failures caused by component contamination. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings. Example 1

[0020] like Figures 1-5 As shown, a zoned dust removal device for a laser cutting machine includes a bed 1. An exchange table 2 is fixedly connected to the front wall of the bed 1. The exchange table 2 is used for loading, unloading, and exchanging workpieces. A protective shell 3 is located on the top of the bed 1, with a three-dimensional cutting mechanism inside the protective shell 3 for cutting operations. The protective shell 3 effectively blocks splatter generated during cutting and prevents the random spread of smoke and dust. A central control console 4 is installed on the side wall of the protective shell 3 away from the exchange table 2. The central control console 4 serves as the control center of the device, electrically connected to various electrical control components in the equipment, and displays the equipment's operating parameters. The interiors of the two side walls and the front wall of the bed 1 are also included. The two parts are connected by a flow chamber. The inner walls of both sides of the bed body 1 are evenly distributed with multiple air inlets 5 that are connected to the flow chamber. The air inlets 5 are the entrances for smoke and dust to enter the flow chamber. The inner walls of both sides of the bed body 1 are provided with opening and closing components 6 at each air inlet 5, which can control the opening and closing of the corresponding air inlet 5 to achieve zoned dust removal. The outer wall of the front end of the bed body 1 is provided with an air outlet 7 that is connected to the flow chamber. The air outlet 7 is the discharge port for smoke and dust in the flow chamber. The air outlet 7 is connected to a fan 8 through a duct. When the fan 8 is running, it can create negative pressure in the flow chamber, providing power for smoke and dust to enter from the air inlet 5, pass through the flow chamber and be discharged from the air outlet 7.

[0021] Furthermore, multiple sets of fans 9 are evenly distributed on the top inner wall of the protective shell. Each set of fans 9 is set above two opposite air inlets 5. The air direction and speed of the fans 9 are adjustable. When the laser cutting generates smoke and dust, the fans 9 can generate a downward directional airflow after starting, guiding the smoke and dust towards the corresponding air inlet 5 below, making it easier for the smoke and dust to be sucked in by the negative pressure of the flow chamber.

[0022] Furthermore, a first camera 10 is installed on the top inner wall of the protective shell 3 near the exchange table 2. The first camera 10 can capture the cutting operation and dust removal effect inside the protective shell 3 in real time. A second camera 11 is installed on the top of the protective shell 3 near the outer outer wall of the exchange table 2. The second camera 11 is used to monitor the loading and unloading progress and placement status of the workpieces on the exchange table 2.

[0023] Furthermore, an opening is provided on the side wall of the protective shell on one side of the center console 4, and a door panel 12 is slidably connected inside the opening. The door panel 12 can be opened and closed by sliding along the opening. An observation window 13 is provided on the door panel 12, through which the cutting process inside the protective shell 3 can be viewed.

[0024] Furthermore, the air inlet 5 has a rectangular structure, and the air outlet 7 has a circular structure.

[0025] Furthermore, the opening and closing assembly 6 includes a rectangular first base plate 61, which is fixedly connected to the air inlet on the inner wall of the bed 1. The length and width of the first base plate 61 are both greater than the length and width of the air inlet 5. Two first guide rails 62 are installed at the middle of the upper and lower ends of the first base plate 61 on the side away from the air inlet 5. A first displacement plate 63 is slidably connected between the two first guide rails 62. A first cylinder 64 is installed on one side of the two first guide rails 62. A protective cover is installed on the outer side of each first cylinder 64 on the inner wall of the bed 1 to protect the first cylinder 64 from cutting. To prevent smoke and dust pollution and impact from splashes, ensuring the stability of cylinder operation, the output end of the first cylinder 64 is fixedly connected to the first displacement plate 63. Multiple rectangular first ventilation slots 65 are evenly distributed on the first base plate 61 between the two first guide rails 62. The first ventilation slots 65 are connected to the air inlet 5. The first displacement plate 63 is evenly distributed with the same number of rectangular first through slots 66 as the first ventilation slots 65. The first through slots 66 penetrate the first displacement plate 63. The distance between adjacent first through slots 66 is greater than the width of the first ventilation slots 65 and less than the distance between adjacent first ventilation slots 65. When the corresponding area air inlet 5 needs to be opened, the first cylinder 64 is activated to push the first displacement plate 63 to slide along the first guide rail 62 until the rectangular first through grooves 66 evenly distributed on the first displacement plate 63 are completely aligned with the rectangular first ventilation grooves 65 evenly distributed on the first base plate 61. Since the first ventilation grooves 65 are pre-connected to the air inlet 5, smoke and dust can enter the flow chamber inside the bed 1 through the first through grooves 66 and the first ventilation grooves 65 in sequence, realizing the dust removal function of this area. When the corresponding area air inlet 5 needs to be closed, the output end of the first cylinder 64 pulls the first displacement plate 63 to slide in the opposite direction along the first guide rail 62. Since the distance between adjacent first through grooves 66 is greater than the width of the first ventilation grooves 65 and less than the distance between adjacent first ventilation grooves 65, the solid part of the first displacement plate 63 completely blocks the first ventilation grooves 65 on the first base plate 61, cutting off the channel for smoke and dust to enter the flow chamber. Example 2

[0026] like Figure 6 As shown, a zoned dust removal device for a laser cutting machine has a structure that is basically the same as that in Embodiment 1, except for the structure of the opening and closing component 6.

[0027] The opening and closing assembly 6 includes a rectangular second base plate 67, which is fixedly connected to the air inlet 5 on the inner wall of the bed 1. The length and width of the second base plate 67 are both greater than the length and width of the air inlet 5. Two second guide rails 68 are installed at the upper and lower ends of the second base plate 67 on the side away from the air inlet 5. A second displacement plate 69 is slidably connected between the two second guide rails 68. A second cylinder 610 is installed on one side of the second base plate 67 on the inner wall of the bed 1. A protective cover is installed on the outer side of each second cylinder 610 on the inner wall of the bed 1 to protect the second cylinder 610 from smoke and dust pollution and impact from flying debris generated during cutting, ensuring the stability of cylinder operation. The output end of cylinder 610 is fixedly connected to the second displacement plate 69. Multiple circular second ventilation slots 611 are evenly distributed on the second base plate 67 between the two second guide rails 68. The second ventilation slots 611 are connected to the air inlet 5. A collar 612 is fixedly connected to the outside of each second ventilation slot 611 in the air inlet 5. Multiple vortex blades 613 are arranged inside the collar 612. The second displacement plate 69 is evenly distributed with the same number of second ventilation slots 611 and is circular in structure. The second through slots 614 penetrate the second displacement plate 69. The distance between adjacent second through slots 614 is greater than the diameter of the second ventilation slots 611 and less than the distance between adjacent second ventilation slots 611.

[0028] Working principle: After the device is started, the fan 8 is connected to the air outlet 7 at the front end of the bed 1 through the duct, forming a stable negative pressure in the flow chamber connected inside the bed 1. According to the real-time position of laser cutting, the fan 9 directly above the smoke generation area and the high concentration area is activated, so that the fan 9 generates a downward directional airflow, guiding the smoke and dust during the cutting process towards the air inlets 5 on both sides of the bed 1 to prevent the smoke from spreading. At the same time, the air inlets on both sides of the bed in the corresponding area are opened through the opening and closing component 6. Under the dual action of the directional airflow of the fan 9 and the adsorption of the negative pressure in the flow chamber, the smoke and dust quickly enter the flow chamber through the air inlet 5 of the corresponding area, and then gather along the flow chamber to the air outlet 7. It is then drawn by the fan 8 through the duct to the purification equipment outside the workshop for further purification. In order to avoid duct blockage and dust overflow, a filter device can be added to the duct section between the fan 8 and the purification equipment to perform preliminary filtration of the smoke and dust passing through, intercept some large dust particles, and ensure smooth airflow.

[0029] During operation, the first camera 10 monitors the cutting status and dust removal effect inside the protective shell 3 in real time, while the second camera 11 monitors the loading and unloading of workpieces on the exchange station 2. All images are fed back to the central control station 4.
