Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically relating to a gas purification mechanism and its laser cutting device. Background Technology

[0002] Side panel sheet metal parts are widely used in equipment manufacturing fields such as cabinets, chassis, home appliances, and automotive parts. Their processing quality directly affects the product's assembly accuracy, appearance, and structural strength. Traditional side panel processing mainly uses processes such as shearing, stamping, flame cutting, and plasma cutting. Shearing and stamping can only achieve straight line or simple hole processing, and have poor adaptability to irregular contours, complex grooves, and free curves. They also require special molds, resulting in long changeover cycles and insufficient flexibility. Flame and plasma cutting have wide heat-affected zones, which can easily lead to side panel warping, slag buildup at the cut, and edge hardening. Subsequent processing requires extensive grinding and reshaping, making it difficult to meet the requirements of high-precision assembly in terms of processing accuracy and consistency. At the same time, the production environment is poor, and energy consumption and scrap rates are high. With the increasing demand for precision manufacturing and flexible production, laser cutting, with its advantages of non-contact processing, high precision, strong contour adaptability, and no need for molds, is gradually becoming the mainstream process for side panel processing.

[0003] Most existing laser cutting devices do not have a gas purification mechanism. During the cutting of side plates, smoke and dust are generated. If the dust is not removed and collected in time, it will move with the air and affect the surrounding air, resulting in a decline in the quality of the working environment. Summary of the Invention

[0016] 2. The purpose of this invention, through the cooperation of the connecting cylinder, channel three, channel four and exhaust shell, is to allow the air flowing from the connector into the clean air tank to converge and disperse directly towards the center of the lower end of the separator plate, reducing the accumulation of air at the periphery. The air gathered at this point can come into sufficient contact with the washing liquid sprayed by the spraying unit, so as to prevent the spraying treatment effect from being weakened due to the air spreading to the periphery. The combination of the guide tube, rotating column one, rotating blade, rotating column two, and baffle plate allows some of the air flowing from connector one to the clean air tank to flow into the washing liquid via the trajectory formed by the lower ends of the connecting tube, channel three, and channel four. The remaining air flows through the trajectory formed by the upper ends of the connecting tube, channel three, and channel four to the center of the lower end of the separator plate, where it is treated by the spraying unit. This two-track treatment method can not only completely utilize the washing liquid to remove some dust and other impurities in the air.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Reference Figure 1 and Figure 2 This invention provides a laser cutting device, which includes a gas purification mechanism and a cutting table 1. A transverse moving module 2 is installed on both sides of the upper end of the cutting table 1. A bracket 3 is installed on the slider of the transverse moving module 2. A longitudinal moving module 4 is installed on the bracket 3. A laser cutting module 5 is installed on the slider of the longitudinal moving module 4.

[0021] The orientation of the laser cutting module 5 is adjusted by the horizontal moving module 2 and the vertical moving module 4 to ensure that the fixed side plate can be cut, thus improving the convenience of cutting.

[0022] The laser cutting module 5 includes a fixing block 51 fixed to the slider of the longitudinal moving module 4. An electric telescopic rod 52 is fixed to one side of the fixing block 51. The movable end of the electric telescopic rod 52 is fixed to the mounting block 53. The laser cutting head 54 is installed at the lower end of the mounting block 53.

[0023] The laser cutting head 54 is moved to the cutting position of the adjacent side plate by the extension of the electric telescopic rod 52, which facilitates the cutting work.

[0024] Example 2 The difference from the above embodiments is that, referring to Figure 1 and Figure 2 A side plate positioning module 6 is installed on the cutting table 1 and inside the horizontal moving module 2.

[0025] The side plate positioning module 6 includes a concave frame 61 fixed to the cutting table 1. A stud 62 is threaded onto the concave frame 61. A handle is installed at the upper end of the stud 62. The lower end of the stud 62 extends into the inner side of the concave frame 61 and is screwed onto a clamping plate 63. The two sides of the clamping plate 63 are movably connected to the inner sidewall of the concave frame 61.

[0026] Before cutting the side plate, place the side plate on the cutting table 1, so that the cutting position of the side plate is in the through groove 84. Rotate the handle to move the stud 62 down, and then the clamping plate 63 presses against the side plate to achieve stable positioning of the side plate, ensuring smooth subsequent cutting and guaranteeing cutting accuracy.

[0027] Example 3 The difference from the above embodiments is that, referring to Figure 1 and Figure 2 The laser cutting module 5 and the cutting table 1 are equipped with an air extraction module 8.

[0028] The exhaust module 8 includes a bamboo-joint tube 81 fixed to both sides of the mounting block 53 and a through groove 84 reserved on the cutting table 1. The lower end of the bamboo-joint tube 81 faces the laser cutting head 54. The upper end of the bamboo-joint tube 81 is connected to a connecting pipe 82. One side of the connecting pipe 82 is connected to a flexible hose 83. The lower end of the through groove 84 is connected to a collection cover 85. The lower end of the collection cover 85 is connected to several steel pipes 86. The lower end of the steel pipes 86 is connected to steel pipes 87. One side of the steel pipes 87 is connected to steel pipes 88. The other side of the flexible hose 83 is connected to steel pipes 88. One side of the steel pipes 88 is connected to a fan 89.

[0029] During the cutting process, the blower 89 operates, drawing the air containing smoke and dust generated during the cutting process through the bamboo joint pipe 81, connecting pipe 82 and hose 83, as well as the through groove 84, collection hood 85, steel pipe one 86 and steel pipe two 87 into steel pipe three 88, and then transporting it to joint one 711 via the blower 89, so as to collect the smoke and dust and transport it to the clean air tank 71 for treatment.

[0030] Example 4 The difference from the above embodiments is that, referring to Figures 3-6 An air purification mechanism includes an air purification module 7 installed on the side of an air extraction module 8.

[0031] The air purification module 7 includes an air purification tank 71, a connector 1 711, a connector 2 712, a partition plate 72, and a spraying unit. Connector 1 711 is connected to one side of the air purification tank 71, and the other side of connector 1 711 is connected to a fan 89. Connector 2 712 is connected to the upper end of the air purification tank 71. The partition plate 72 is fixed to the inner surface of the air purification tank 71 and has several pre-drilled holes. The spraying unit includes a water pump 73 mounted on the outside of the air purification tank 71. One side of the water pump 73 extends to the lower end inside the air purification tank 71, and the other side of the water pump 73 is connected to a channel 1 731. The other side of channel 1 731 is fixed to the inner surface of the air purification tank 71. Several channels 2 732 located inside the air purification tank 71 are connected to channel 1 731. Several evenly arranged atomizing heads 733 are connected to the downward-facing wall surface of each channel 2 732.

[0032] During the cutting process, air carrying smoke and dust flows into the air purification tank 71 through connector 711 installed on the air purification tank 71, and then passes through the partition plate 72 installed in the air purification tank 71. At this time, the water pump 73 installed outside the air purification tank 71 operates, and the water pump 73 delivers the washing liquid from the lower end of the air purification tank 71 to the channel 731. The channel 731 distributes the washing liquid to several channels 732 in the air purification tank 71, and then sprays it onto the activated carbon particles on the partition plate 72 and the passing air through several atomizing heads 733 at the lower end of the channel 732. The washing liquid strips the smoke and dust in the air, and the stripped air is released from connector 712 installed at the upper end of the air purification tank 71.

[0033] Reference Figures 5-7A connecting cylinder 74 is installed inside the clean air tank 71 at connector 711. The inner diameter of connector 711 is smaller than the inner diameter of the connecting cylinder 74 connected to the side of connector 711. The side of connecting cylinder 74 that contacts the inner surface of clean air tank 71 is adapted to the inner surface of clean air tank 71. This structure allows the connecting cylinder 74 to have tight contact with the inner surface of clean air tank 71 to prevent smoke and dust from moving directly towards the periphery of clean air tank 71. One side of connecting cylinder 74 is connected to channel 3 75. The end of channel 3 75 that is furthest from connecting cylinder 74 is connected to channel 4 76, which is vertically located at the center of the bottom of the partition plate 72. The upper end of channel 4 76 is connected to exhaust shell 77. The upper end of the gas casing 77 is equipped with several circumferentially arranged exhaust sections, each with a uniformly arranged opening 771. During operation, the air in the connector 1 711 flows to the connecting cylinder 74 before being connected through the channel 3 75 and guided to the channel 4 76. Finally, the air is gathered and dispersed from the opening 771 of the exhaust section at the upper end of the exhaust casing 77 towards the center of the clean air tank 71, reducing the gathering of air at the sides. The air gathered at the center can then have sufficient contact with the washing liquid sprayed by the spraying unit. The washing liquid can strip away dust and other particles in the air, ensuring that the device can completely strip away dust and other particles in the air, thereby enhancing the stripping function of the device.

[0034] Because channel 4 76 is vertically installed at the bottom of the spraying unit, when the spraying unit sprays the washing liquid into the clean air tank 71, some of the washing liquid moves downwards under its own weight. The vents 771 arranged in the exhaust section at the top of the exhaust shell 77 provide a passage for the downward-moving washing liquid to flow into channel 4 76, allowing the washing liquid to successfully flow into the middle. The air flowing into channel 4 76, before spreading from the top of the exhaust shell 77 to the periphery, comes into contact with the incoming washing liquid. The washing liquid that comes into contact with the air can strip away some dust and other particles in the air, thereby reducing the content of dust and other particles in the air. After this pre-treatment process, when the air moves upwards to the separator plate 72, the content of dust and other particles faced by the subsequently sprayed washing liquid when it performs a second treatment on the air is greatly reduced, thus simplifying the treatment of the air at this point and ensuring the treatment function and speed of the entire device.

[0035] Example 5 The difference from the above embodiments is that, referring to Figure 5The lower end of channel four 76 extends into the washing liquid at the lower end of the clean gas tank 71. A check switch is installed at the lower end of channel four 76. Channel three 75 includes a horizontal part 751, an arched part 752, and an inclined part 753 connected sequentially from the connecting cylinder 74 to the wall of channel four 76. The horizontal part 751, the arched part 752, and the inclined part 753 are an integral structure. When the washing liquid moves from the upper end of the exhaust shell 77 into channel four 76, because the lower end extends into the washing liquid at the lower end of the clean gas tank 71, the washing liquid moves along the lower end of channel four 76 into the washing liquid at the lower end of the clean gas tank 71 by its own weight. This prevents the washing liquid from accumulating in channel four 76 and prevents backflow of the washing liquid, ensuring the normal operation of the device.

[0036] The air moving into channel 4 76 is dispersed along multiple paths. Some air is dispersed from the upper end of exhaust shell 77 towards the center of the upper end of partition plate 72. During the upward movement, this air will come into complete contact with the washing liquid sprayed by the spraying unit, thereby stripping away dust and other particles from the air. The remaining air can move directly from the opening at the lower end of channel 4 76 into the washing liquid at the lower end of the clean air tank 71. With the cooperation of the washing liquid, dust and other waste in the air can be quickly adsorbed into the washing liquid, achieving the purpose of decontamination and air purification. This multi-path air dispersion method increases the contact range between air and washing liquid, allowing dust and other particles in the air to be completely stripped away by the washing liquid, thus enhancing the air purification function of the device.

[0037] Example 6 The difference from the above embodiments is that, referring to Figures 8-11 A cylindrical guide tube 761 is connected to the channel 4 76 and is located at the bottom of the outlet end of the inclined section 753. A rotating column 762 is screwed between the guide tube 761 and the clean air tank 71. Several circumferential rotating blades 763 are fixed to the outer wall of the rotating column 762 and are in contact with the inner surface of the guide tube 761. A motor 764 is fixed to the side of the rotating column 762 outside the clean air tank 71.

[0038] Driven by motor 764, several rotating blades 763 on rotating column 762 rotate along the inner surface of guide cylinder 761. This rotating structure, due to the strong guiding effect of the rotating blades 763, automatically guides the air in connector 711 through the trajectory formed by connecting cylinder 74, channel 3 75, and the lower end of channel 4 76 directly into the washing liquid at the lower end of clean air tank 71. Under this strong guidance, the air generally follows this trajectory to the washing liquid, with very little air flowing away through the trajectory formed by connecting cylinder 74, channel 3 75, and the upper end of channel 4 76. The air flowing into clean air tank 71... 1. In the lower end of the washing liquid, the air forms a gas cloud that floats upwards. During this process, dust and other impurities in the air are stripped off by the washing liquid, which can accelerate the reduction of dust and other impurities in the air, thereby achieving the purpose of initial air purification. Compared with the direct movement of air to the activated carbon particles on the separator plate 72, the contact with the washing liquid can significantly reduce the impact of air on the activated carbon particles on the separator plate 72, reduce wear, extend the replacement cycle of activated carbon particles, prevent the atomizing head 733 from becoming blocked, save time and effort, and make the air purification process proceed in an orderly and stable manner, so as to maintain a stable air purification speed.

[0039] Example 7 The difference from the above embodiments is that, referring to Figure 9 and Figure 10 The upper end of the exhaust housing 77 is connected to the rotating column 765 via a slewing bearing. The rotating column 765 is connected to the outer ring 766, and the outer ring 766 is connected to several circumferentially arranged connecting columns 767. The side of the connecting column 767 that is farther from the outer ring 766 is connected to a baffle plate 768 that contacts the upper wall of the exhaust housing 77.

[0040] Motor 764 can change from rapid rotation to slow rotation through timed action, thereby pulling several rotating blades 763 on rotating column 762 to rotate along the inner surface of guide cylinder 761. At this time, rotating column 762 pulls rotating blades 763 to move slowly along the inner surface of guide cylinder 761. The guiding effect of rotating blades 763 is significantly smaller than that of rotating blades 763 when rotating rapidly in embodiment six. The guiding and gathering effect on the air discharged from connector 711 is insufficient. Thus, some air can be allowed to flow out of connecting cylinder 74, channel 75 and the connecting tube. The trajectory formed by the lower end of channel 76 moves into the scrubbing liquid. Compared with the self-movement in embodiment 5, this can prevent most of the air from flowing away through the trajectory formed by the connecting cylinder 74, channel 3 75 and the upper end of channel 4 76. However, the remaining air is dispersed from trajectory 2 to the center of the lower end of the separator 72, and scrubbing liquid is sprayed out by the spraying unit for treatment. The treatment methods of these two trajectories can not only completely use the scrubbing liquid to remove some dust and other impurities in the air, but also use the spraying unit to perform thorough treatment on the remaining air, thereby enhancing the air purification function and speed.

[0041] When the rotating column 762 rotates slowly, the rotating column 765, which is driven by it, rotates accordingly. This, in turn, pulls the baffle plate 768 to rotate circumferentially on the upper end of the exhaust housing 77 via the outer ring 766 and connecting column 767. When the baffle plate 768 rotates to the point where it is directly in contact with the exhaust section, because the baffle plate 768 is a sealing structure and the span of the exhaust section is greater than the span of the baffle plate 768, some of the openings 771 on each exhaust section at the upper end of the exhaust housing 77 are exposed due to the cover of the baffle plate 768, thus achieving partial opening. As the baffle plate 768 continues to rotate, when the baffle plate 768 that was originally directly in contact with the exhaust section... When rotated to the area between a pair of adjacent exhaust sections, the openings 771 on each exhaust section at the upper end of the exhaust housing 77 are unblocked and fully open. During the period when the air is guided by each of the first and second free trajectories, the openings 771 on the pair of exhaust sections continuously perform intermittent partial covering and full opening actions, which can adjust the air passage conditions of the exhaust housing 77. This can reduce the speed at which the air flows to the lower center of the separator plate 72 on the second trajectories, allowing the air sufficient time to fully contact the washing liquid sprayed in the spraying unit. This allows the washing liquid to treat the air more thoroughly and completely, enhancing the air purification function of the device.

[0042] To achieve the purpose of rotating both rotating column 1 762 and rotating column 2 765, a parasol disc 1 769 located in the clean air tank 71 is fixedly connected to the wall of rotating column 1 762. A matching parasol disc 2 7610 is installed on the side of parasol disc 1 769. Several teeth are reserved on the outer circumference of parasol disc 1 769 and parasol disc 2 7610 and are connected to each other through the teeth. A rotating column 3 7611 is fixedly connected to the upper center of parasol disc 2 7610. A sprocket 1 7612 is fixedly connected to the upper end of rotating column 3 7611. A matching chain 7613 is installed on sprocket 1 7612. A matching sprocket 2 7614 is installed inside the chain 7613. 614 is fixed to the upper end of the rotating column 2 765. The support frame 78 is fixed between the inner wall of the clean air tank 71 and the lower end of the exhaust shell 77. The rotating column 3 7611 is screwed between the upper and lower ends of the support frame 78 via a slewing bearing. When the rotating column 1 762 rotates, the umbrella disc 1 769 on the rotating column 1 762 pulls the umbrella disc 2 7610 to rotate, which in turn makes the rotating column 3 7611 on the umbrella disc 2 7610 rotate. When the rotating column 3 7611 rotates, through the cooperation of the sprocket 1 7612, the chain 7613 and the sprocket 2 7614, the rotating column 2 765 is pulled to rotate, thereby achieving the purpose of rotating the rotating column 1 762 and the rotating column 2 765 rotating together.
