Description
Technical Field
[0001] The utility model relates to the technical field of laser tube cutting machines, in particular to a dust extraction device before material connection of a laser tube cutting machine. Background Art
[0002] When cutting a workpiece, a laser tube cutting machine uses a high-power density laser beam to illuminate the workpiece, rapidly melting and vaporizing the material. During this process, the material's surface temperature rises sharply, causing violent physical and chemical reactions within the material, generating smoke and dust. This smoke and dust is collected at the laser tube cutting machine's front-end to protect worker health and environmental hygiene.
[0003] At present, there are two main ways to collect smoke and dust from the front feeding device of the laser tube cutting machine.
[0004] 1. The front material receiving cover is designed to be closed, with the upper part connected to the laser cutting box of the cutting machine. The air duct of the laser cutting box is used to suck out the smoke and dust. The air duct in the cutting room mainly sucks the cutting smoke and dust from the laser head area, which is located at a lower position. However, the gas in the cutting room will diffuse upwards, and the air duct has difficulty sucking the smoke and dust at high places, resulting in poor dust collection effect.
[0005] Second, the factory workshop has a dust collection duct reserved for the top. The upper cover of the front material connection is made into a shape similar to the upper cover of the range hood, with an air duct opening on the top, which is connected to the dust collection duct at the top of the workshop to collect smoke and dust. This structure is only suitable for workshops with space reserved for dust collection ducts. If the workshop is small, this dust collection method is not suitable and has poor applicability. Utility Model Content
[0006] In order to solve the above problems, the present application provides a dust extraction device before the laser tube cutting machine is connected to the material.
[0007] This application provides a dust extraction device for a laser tube cutting machine before material connection, which adopts the following technical solutions:
[0008] A dust extraction device for a front-end material receiving machine of a laser tube cutting machine comprises a dust extraction hood connected to a laser cutting box, the dust extraction hood is detachably connected to the laser cutting box, a smoke collector is provided on the side of the laser cutting box facing away from the dust extraction hood, a dust extraction pipe is provided at one end of the smoke collector close to the laser cutting box, a fan is provided inside the smoke collector, one end of the dust extraction pipe in the length direction is connected to the exhaust port of the fan, and the other end of the dust extraction pipe in the length direction passes through the laser cutting box and is connected to the dust extraction hood, the dust extraction pipe is located at the upper end portion of the dust extraction hood and is interconnected with the dust extraction hood.
[0009] Optionally, the dust extraction hood includes an upper hood, which includes a bottom hood and a top hood that are interconnected. The top hood is located above the bottom hood, and the side walls of the top hood are all inclined, and the width of the top hood gradually decreases from bottom to top.
[0010] Optionally, the dust hood also includes a smoke collection box, and the dust extraction pipe is detachably connected to the upper end of the smoke collection box. The smoke collection box is located above the upper cover and is interconnected with the upper cover. The width of the upper cover is greater than the width of the smoke collection box. The end of the smoke collection box away from the laser cutting box is also inclined, and the width of the smoke collection box gradually decreases from bottom to top.
[0011] Optionally, a plurality of pipe racks for limiting the position of the dust extraction pipe are fixedly connected to the side walls of the laser cutting box, and the plurality of pipe racks are all located inside the laser cutting box.
[0012] In summary, this application includes at least one of the following beneficial technical effects:
[0013] 1. During the process of cutting the pipe inside the laser cutting box, smoke and dust are generated. Under the suction effect of the fan, the smoke and dust flow into the dust hood, and then are sucked into the dust extraction pipe, and finally flow into the smoke and dust collector to complete the collection of the smoke and dust, with a good smoke and dust collection effect; the dust extraction hood has a simple structure and low manufacturing cost. There is no need to reserve dust extraction pipes in the workshop, and there are no requirements for the structure of the workshop, so it has strong applicability;
[0014] 2. Under the action of the fan, the smoke flows into the interior of the dust hood.

[0015] 3. Under the action of the fan, the smoke flows into the interior of the dust hood. After passing through the upper hood, the smoke flows along the inclined angle of the side wall of the smoke collection box, which guides the smoke and increases the flow rate of the smoke, making it easier for the smoke to enter the interior of the dust extraction pipe, thereby improving the collection efficiency of the smoke.
[0016] 4. The dust extraction pipe is arranged inside the laser cutting box through a pipe rack, which can save space. There is no need to reserve a dust extraction pipe in the workshop, and there is no requirement for the structure of the workshop, so it has strong applicability. Moreover, the dust extraction pipe is relatively concealed and cannot be seen from the outside of the laser cutting box. The layout of the dust extraction pipe is relatively simple.

[0021] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0022] The embodiment of the present application discloses a dust extraction device for a laser tube cutting machine before material connection.
[0023] Reference Figure 1 and Figure 2 , a dust extraction device for a front-loading material connection of a laser tube cutting machine includes a dust extraction hood 1 connected to the laser cutting box 100, and the dust extraction hood 1 is detachably connected to the laser cutting box 100. A smoke dust collector 2 is provided on the side of the laser cutting box 100 facing away from the dust extraction hood 1, and a dust extraction pipe 3 is provided at one end of the smoke dust collector 2 close to the laser cutting box 100. A fan is provided inside the smoke dust collector 2, and one end of the dust extraction pipe 3 in the length direction is connected to the exhaust port of the fan, and the other end of the dust extraction pipe 3 in the length direction passes through the laser cutting box 100 and is connected to the dust extraction hood 1. The dust extraction pipe 3 is located at the upper end of the dust extraction hood 1 and is communicated with the dust extraction hood 1; smoke and dust are generated when the laser cutting box 100 cuts the pipeline, and the air is exhausted by the fan, and the smoke and dust flow to the inside of the dust extraction hood 1, and then are sucked into the dust extraction pipe 3, and finally flow to the inside of the smoke and dust collector 2, completing the collection of the smoke and dust.
[0024] Reference Figure 1 and Figure 2 Before using the dust extraction device, it is first necessary to install the dust extraction pipe 3 and the dust extraction hood 1; a number of pipe racks 4 for limiting the position of the dust extraction pipe 3 are fixedly connected to the side wall of the laser cutting box 100. By fixing the number of pipe racks 4 to the inside of the laser cutting box 100 and then arranging the dust extraction pipe 3 inside the number of pipe racks 4, the arrangement of the dust extraction pipe 3 is relatively simple; making the dust extraction pipes 3 all fit on the side walls of the laser cutting box 100 can save space, and there is no need to reserve 3 dust extraction pipes in the workshop, and there are no requirements for the structure of the workshop, and the applicability is strong; and the dust extraction pipes 3 are relatively concealed, and the dust extraction pipes 3 cannot be seen from the outside of the laser cutting box 100, which is more beautiful.
[0025] Reference Figure 1 and Figure 2 After connecting the dust extraction pipe 3 to the dust extraction hood 1, the dust extraction pipe 3 can be connected to the dust extraction hood 1; the dust extraction hood 1 includes a connecting pipe 15, the connecting pipe 15 is inserted into the interior of the laser cutting box 100, and then the dust extraction pipe 3 and the connecting pipe 15 are connected by plugging, which has a simple structure and is easy to connect.
[0026] Reference Figure 1 and Figure 3 , and then the dust hood 1 can be connected to the laser cutting box 100. The dust hood 1 and the laser cutting box 100 can be connected by bolts, or by other means. The dust hood 1 and the laser cutting box 100 can be connected.
[0027] A plurality of connection holes can be opened on the side wall of the laser cutting box 100, and the height of the dust hood 1 can be adjusted according to the height of the cutting device in the laser cutting box 100. The dust hood 1 can be connected by bolts, so that the dust hood 1 can achieve a better dust extraction effect and improve the applicability of the dust hood 1. The height of the dust hood 1 can also be adjusted to subsequently suck in smoke and dust at high places, thereby improving the dust extraction effect.
[0028] Reference Figure 1 and Figure 3 , use the laser cutting box 100 to cut the pipe, and smoke and dust are generated in the cutting process. By operating the fan to exhaust air, the smoke and dust flow into the interior of the dust hood 1 under the exhaust action of the fan; the dust hood 1 includes an upper cover 11, and the upper cover 11 includes a bottom cover 13 and a top cover 12 that are interconnected. The top cover 12 is located above the bottom cover 13, and the side walls of the top cover 12 are all inclined. The width of the top cover 12 gradually decreases from bottom to top; the smoke and dust flow along the inclined angle of the top cover 12, which guides the smoke and dust, thereby increasing the flow rate of the smoke and dust.
[0029] Reference Figure 1 and Figure 2 The dust extraction hood 1 also includes a smoke collection box 14, and a connecting pipe 15 is arranged at the upper end of the smoke collection box 14. The smoke collection box 14 is located above the upper cover 11 and is connected to the upper cover 11. The width of the upper cover 11 is greater than the width of the smoke collection box 14. The end of the smoke collection box 14 away from the laser cutting box 100 is also inclined, and the width of the smoke collection box 14 gradually decreases from bottom to top; after the smoke passes through the upper cover 11, it flows along the inclined angle of the side wall of the smoke collection box 14, which guides the smoke. At this time, the smoke flows in the direction close to the connecting pipe 15, thereby increasing the flow rate of the smoke, and the smoke flows from the connecting pipe 15 to the dust extraction pipe 3, so that the smoke can more easily enter the interior of the dust extraction pipe 3, and then the smoke enters the interior of the smoke collector 2, and then the smoke is processed, and the smoke collection efficiency is high.
[0030] Among them, the smoke dust collector 2 is an existing technology, which can remove particulate matter and harmful gases in the smoke and dust, and will not be described in detail in this article.
[0031] The implementation principle of the dust extraction device before the laser tube cutting machine in the embodiment of the present application is as follows: after the dust extraction pipe 3 is installed on several pipe racks 4, the dust extraction pipe 3 is all fitted on the side wall of the laser cutting box 100, which can save space. There is no need to reserve 3 dust extraction pipes in the workshop, and there is no requirement for the structure of the workshop, so it has strong applicability; then, after the dust extraction pipe 3 is connected to the dust extraction hood 1, the dust extraction hood 1 is installed on the laser cutting box 100 to complete the fixation; then the laser cutting box 100 can be used to cut the pipeline, and the smoke and dust generated during the cutting process are exhausted by the fan. The smoke flows into the interior of the dust hood 1 and flows along the inclination angle of the top cover 12, which guides the smoke. Then the smoke enters the smoke collection box 14 and flows along the inclination angle of the side wall of the smoke collection box 14, which guides the smoke. At this time, the smoke flows in the direction close to the connecting pipe 15, thereby increasing the flow rate of the smoke. The smoke flows from the connecting pipe 15 to the dust extraction pipe 3, so that the smoke can more easily enter the interior of the dust extraction pipe 3, and then the smoke enters the interior of the smoke dust collector 2, and then the smoke is processed, and the smoke collection efficiency is high.
[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
