[0001] The present invention relates to the technical field of cutting, and particularly to a cutting device for the production of industrial sewing machine accessories. Background Art

[0002] In the field of production and manufacturing of industrial sewing machine accessories, the cutting process is a key processing link, and its processing quality and efficiency directly affect the quality and production efficiency of sewing machine accessories. With the continuous improvement of the market's requirements for product accuracy and performance in the industrial sewing machine field, as well as the gradual expansion of the production scale, more stringent requirements are put forward for the cutting equipment in the accessory production process.

[0003] In the prior art, the debris generated during the cutting of traditional cutting equipment is prone to fly everywhere, which not only pollutes the working environment, increases the difficulty of subsequent cleaning work, but also may pose a potential threat to the physical health of operators.

[0008] A protective component, on the outer side of which a telescopic cylinder is fixedly connected. The outer side of the telescopic cylinder is fixedly connected to the top of the mounting frame. The protective component is used to block the dust generated during the cutting of the disc saw blade. On the outer side of the protective component, a telescopic pipe is fixedly connected. The end of the telescopic pipe away from the protective component is clamped with a filtering component. On the outer side of the protective component, an adsorption component is fixedly connected. The protective component includes a protective shell. On both sides of the protective shell, guide rods are slidably connected. At the bottom of the guide rods, a dust collection shell is fixedly connected. At the top of the dust collection shell, a compression spring is fixedly connected; the suction fan rotates together with the hollow rotating shaft, and through the filtering component, the gas in the telescopic pipe and the protective component is extracted, so that a negative pressure state is generated in the protective component. At this time, the dust blocked and collected by the protective component can be adsorbed in the filtering component along the telescopic pipe. At the same time, the adsorption component can operate synchronously with the rotation of the spline shaft, so as to absorb the fumes generated during cutting.

[0009] The filtering component includes a shell. At the center of the shell, a rotating rod is rotatably connected. On the outer wall of the rotating rod, a connecting frame is fixedly connected. Inside the connecting frame, a clamping cylinder is fixedly connected. Inside the clamping cylinder, a filter element is movably installed. When the adsorption capacity of the filter element decreases, only need to rotate the rotating rod to rotate the clamping cylinder and the filter element installed on the other side of the connecting frame to the right below the telescopic pipe.

[0010] Preferably, the outer side of the hollow rotating shaft is rotatably connected to the inner side of the mounting frame. The end of the spline shaft away from the hollow rotating shaft is fixedly connected to the inner side of the adsorption component. The disc saw blade is located inside the protective component. When the sewing machine parts pass under the protective shell, the sewing machine parts will push the dust collection shell upward, and then make the guide rods slide upward along both sides of the protective shell, so that the compression spring is compressed by force.

[0011] Preferably, the protective net is located on the side of the suction fan close to the drive motor. The bottom of the filtering component is fixedly connected to the top of the mounting frame. The outer side of the protective shell is fixedly connected to the output end of the telescopic cylinder. The top end of the compression spring is fixedly connected to the outer side of the protective shell. The inner side of the protective shell is rotatably connected to the outer side of the spline shaft. Under the elastic force of the compression spring, the dust collection shell can be pressed on the surface of the passing sewing machine parts.

[0012] Preferably, the clamping cylinders are arranged annularly along the central axis of the connecting frame. At the bottom of the rotating rod, a limiting block is fixedly connected. On the inner wall of the shell, a guiding frame is slidably connected. On the outer side of the guiding frame, a convex block is fixedly connected. On the outer side of the convex block, a return spring is fixedly connected. On the outer side of the shell, a threaded column is fixedly connected. When the filter element is working normally, the cutting equipment may generate vibrations, which may cause a slight displacement of the guiding frame. At this time, the nut on the outer side of the threaded column can be rotated to press the guiding frame toward the side close to the shell, so as to prevent the guiding frame from shaking due to vibrations.

[0013] Preferably, the bottom of the outer shell is fixedly connected to the top of the mounting frame. The top of the clamping cylinder is clamped to the side of the telescopic tube away from the protection component. The outer side of the limiting block is slidably connected to the outer side of the convex block, and both the limiting block and the convex block are located inside the outer shell. One end of the return spring away from the convex block is fixedly connected to the inner side of the outer shell. Under the elastic force of the return spring, the guiding frame drives the convex block to just abut against the depression on the surface of the limiting block, thereby restricting the rotation of the rotating rod and the connecting frame.

[0014] Preferably, the adsorption component includes a mounting plate. The outer side of the mounting plate is fixedly connected with an air inlet shell. A centrifugal fan is rotatably connected to the inner side of the air inlet shell. A hose is fixedly connected to the outer side of the air inlet shell. The bottom end of the hose is fixedly connected with an adsorption plate. A fixing component is annularly arranged on the outer side of the air inlet shell. When the centrifugal fan rotates, its blades rotate at a high speed, causing the air in the air inlet shell to generate a centrifugal force. The air is quickly thrown to the outer side of the air inlet shell, thereby forming a low-pressure area in the central area of the air inlet shell. Since the adsorption plate is connected to the air inlet shell through the hose and the adsorption plate is located near the cutting area, under the strong action of the low pressure in the central area of the air inlet shell, the flue gas generated in the cutting area will quickly be sucked into the hose through the pores on the adsorption plate.

[0015] Preferably, the outer side of the mounting plate is fixedly connected to the outer side of the protection shell. The outer side of the adsorption plate is fixedly connected to the outer side of the dust collection shell. One end of the spline shaft away from the hollow rotating shaft is fixedly connected to the outer side of the centrifugal fan. The air inlet shell is fixed to the protection shell through the mounting plate. At this time, the spline shaft synchronously drives the centrifugal fan in the air inlet shell to rotate.

[0016] Preferably, the fixing component includes an annular fixing plate. A buffer spring is fixedly connected to the top of the annular fixing plate. The top end of the buffer spring is fixedly connected with a mounting cylinder. An activated carbon cylinder is movably installed inside the mounting cylinder. A fixing cylinder is slidably connected to the outer side of the mounting cylinder. A cover plate is threadedly connected to the top of the fixing cylinder. The flue gas will pass through the activated carbon cylinder installed in the fixing component on the outer side of the air inlet shell. The activated carbon cylinder can adsorb harmful gases and odor molecules in the flue gas.

[0017] Preferably, the bottom of the annular fixing plate is fixedly connected to the outer side of the air inlet shell. The inner side of the annular fixing plate is fixedly connected to the outer side of the fixing cylinder. The bottom of the cover plate is in contact with the top of the activated carbon cylinder. When the activated carbon cylinder reaches the adsorption saturation state, the cover plate at the top of the fixing cylinder can be easily unscrewed. At this time, the elastic force of the buffer spring is released and drives the mounting cylinder to move away from the annular fixing plate. At this time, the mounting cylinder can drive the activated carbon cylinder to pop out of the fixing cylinder.

[0018] (III) Beneficial effects

[0019] The present invention provides a cutting device for the production of industrial sewing machine accessories. It has the following beneficial effects:

[0020] (1). The device drives the protective component and the spline shaft to move by setting a telescopic cylinder. At this time, the spline shaft can slide along the inner side of the hollow rotating shaft while rotating with the hollow rotating shaft, so as to adjust the position of the disc saw blade relative to the mounting frame, thereby expanding the cutting range of the disc saw blade. At the same time, the telescopic tube can contract synchronously with the movement of the protective component to ensure that the inside of the protective component is always in a negative pressure environment during cutting. In fact, the protective net can protect the suction fan.

[0021] (2). The device is provided with a protective component. When the sewing machine accessory passes under the protective shell, the sewing machine accessory will push the dust collecting shell upward, so that the guide rod slides upward along both sides of the protective shell, compressing the compression spring. At this time, under the elastic force of the compression spring, the dust collecting shell can be pressed on the surface of the passing sewing machine accessory, reducing the diffusion of debris in the working area, keeping the working environment clean, and reducing the difficulty of subsequent cleaning work.

[0022] (3). The device is provided with a protective component. The inside of the protective shell and the dust collecting shell always maintains a negative pressure environment. The dust collected inside will be sucked into the telescopic tube and then enter the filtering component for collection. The dust generated by cutting is sucked in time to prevent the dust from overflowing into the surrounding environment, and the dust is collected into the filtering component in time, avoiding the secondary pollution caused by the dust flying again due to equipment vibration and other reasons after accumulating in the protective shell and the dust collecting shell, which helps to maintain the cleanliness of the entire cutting device and its surrounding environment.

[0023] (4). The device is provided with a filtering component. When the dust enters the filtering component, under the suction of the suction fan, the dust will be adsorbed on the surface of the filter element in the clamping cylinder. After long-term use, when the adsorption capacity of the filter element decreases, only need to rotate the rotating rod to rotate the clamping cylinder and the filter element installed on the other side of the connecting frame to the directly below of the telescopic tube. The operation is simple, reducing the difficulty and time cost of maintenance.

[0024] (5). The device is provided with a rotating rod. When rotating the rotating rod, the limit block at its bottom rotates synchronously inside the outer shell. At this time, the limit block slides along the surface of the convex block and forces the return spring to be compressed. When the position of the connecting frame is adjusted, at this time, under the elastic force of the return spring, the guide frame drives the convex block to just abut against the depression on the surface of the limit block, thereby restricting the rotation of the rotating rod and the connecting frame, ensuring a stable flow channel of the dust in the filtering component, and avoiding dust leakage or ineffective entry into the filter element for filtration due to the offset of the filter element position.

[0025] (6). By setting the threaded posts, when the filter element is working properly, the cutting equipment may vibrate, which may cause slight displacement of the guide frame. At this time, the nut outside the threaded post can be rotated to press the guide frame against the side close to the housing, preventing the guide frame from shaking due to vibration and ensuring the stability of its position.

[0026] (7). By setting the adsorption component, when the centrifugal fan rotates, its blades rotate at high speed, causing the air in the air inlet housing to generate centrifugal force. The air is quickly thrown to the outside of the air inlet housing, thus forming a low-pressure area in the central area of the air inlet housing. Since the adsorption plate is connected to the air inlet housing through a hose and the adsorption plate is located near the cutting area, under the strong action of the low pressure in the central area of the air inlet housing, the flue gas generated in the cutting area will quickly be sucked into the hose through the pores on the adsorption plate and then quickly enter the air inlet housing, preventing the flue gas from spreading.

[0027] (8). By setting the buffer spring, after the activated carbon cylinder reaches the adsorption saturation state, the cover plate on the top of the fixed cylinder can be easily unscrewed. At this time, the elastic force of the buffer spring is released, driving the installation cylinder to move away from the side of the annular fixed plate. At this time, the installation cylinder can drive the activated carbon cylinder to pop out of the fixed cylinder, facilitating the removal and replacement of a new activated carbon cylinder, so as to continuously maintain the excellent purification effect of the adsorption component on the cutting flue gas, ensure the cleanliness of the air in the working environment, and protect the physical health of the operators.

[0038] Embodiment: Please refer to Figure 1-8 , the present invention provides a technical solution: a cutting device for the production of industrial sewing machine accessories, including:

At the same time, the protection assembly 9 shields the cutting splashes. During this process, the air suction fan 14 rotates together with the hollow rotating shaft 6, and the gas in the telescopic pipe 11 and the protection assembly 9 is extracted through the filtering assembly 12, so that a negative pressure state is generated in the protection assembly 9. At this time, the dust collected and shielded by the protection assembly 9 can be adsorbed in the filtering assembly 12 along the telescopic pipe 11. At the same time, the adsorption assembly 10 can operate synchronously with the rotation of the spline shaft 7, so as to absorb the fumes generated during cutting; wherein, a telescopic cylinder 15 is provided to drive the protection assembly 9 and the spline shaft 7 to move. At this time, the spline shaft 7 can slide along the inner side of the hollow rotating shaft 6 while rotating with the hollow rotating shaft 6, so as to adjust the position of the disc saw blade 8 relative to the installation frame 4, and further expand the cutting range of the disc saw blade 8. At the same time, the telescopic pipe 11 can contract synchronously with the movement of the protection assembly 9 to ensure that the protection assembly 9 is always in a negative pressure environment during cutting. In fact, the protective net 13 can protect the air suction fan 14.

[0040] The protective component 9 is fixedly connected to the outer side of the telescopic cylinder 15, and the outer side of the telescopic cylinder 15 is fixedly connected to the top of the mounting frame 4. The protective component 9 is used to block the dust generated during the cutting of the disc saw blade 8. The outer side of the protective component 9 is fixedly connected to the telescopic pipe 11. The end of the telescopic pipe 11 away from the protective component 9 is clamped with a filtering component 12. The outer side of the protective component 9 is fixedly connected to an adsorption component 10. The protective component 9 includes a protective shell 91. Guide rods 93 are slidably connected to both sides of the protective shell 91. The bottom of the guide rod 93 is fixedly connected to a dust collection shell 92. The top of the dust collection shell 92 is fixedly connected to a compression spring 94. The protective net 13 is located on the side of the suction fan 14 close to the drive motor 5. The bottom of the filtering component 12 is fixedly connected to the top of the mounting frame 4. The outer side of the protective shell 91 is fixedly connected to the output end of the telescopic cylinder 15. The top end of the compression spring 94 is fixedly connected to the outer side of the protective shell 91. The inner side of the protective shell 91 is rotatably connected to the outer side of the spline shaft 7. When the sewing machine parts pass below the protective shell 91, the sewing machine parts will push the dust collection shell 92 upward, so that the guide rod 93 slides upward along both sides of the protective shell 91, causing the compression spring 94 to be compressed. At this time, under the elastic force of the compression spring 94, the dust collection shell 92 can be pressed on the surface of the passing sewing machine parts, reducing the diffusion of debris in the working area, keeping the working environment clean, and reducing the difficulty of subsequent cleaning work. During this process, a negative pressure environment is always maintained inside the protective shell 91 and the dust collection shell 92. The dust collected inside will be sucked into the telescopic pipe 11 and then enter the filtering component 12 for collection. The dust generated by cutting is sucked in time to prevent the dust from overflowing into the surrounding environment, and the dust is collected in the filtering component 12 in time, avoiding the secondary pollution caused by the dust flying again due to equipment vibration and other reasons after accumulating in the protective shell 91 and the dust collection shell 92, which helps to maintain the cleanliness of the entire cutting equipment and its surrounding environment

[0041] The filtering component 12 includes a housing 121. A rotating rod 122 is rotatably connected to the center of the housing 121. A connecting frame 123 is fixedly connected to the outer wall of the rotating rod 122. A clamping cylinder 124 is fixedly connected to the inner side of the connecting frame 123. A filter element 125 is movably installed inside the clamping cylinder 124; the clamping cylinders 124 are arranged annularly along the central axis of the connecting frame 123. A limiting block 126 is fixedly connected to the bottom of the rotating rod 122. A guiding frame 127 is slidably connected to the inner wall of the housing 121. A convex block 129 is fixedly connected to the outer side of the guiding frame 127. A return spring 128 is fixedly connected to the outer side of the convex block 129. A threaded column 120 is fixedly connected to the outer side of the housing 121. The bottom of the housing 121 is fixedly connected to the top of the mounting frame 4. The top of the clamping cylinder 124 is clamped to the side of the telescopic tube 11 away from the protection component 9. The outer sides of the limiting block 126 and the convex block 129 are slidably connected, and both the limiting block 126 and the convex block 129 are located inside the housing 121. The end of the return spring 128 away from the convex block 129 is fixedly connected to the inner side of the housing 121. When dust enters the filtering component 12, under the suction of the suction fan 14, the dust will be adsorbed on the surface of the filter element 125 inside the clamping cylinder 124. After long-term use, when the adsorption capacity of the filter element 125 decreases, only need to rotate the rotating rod 122 to rotate the clamping cylinder 124 and the filter element 125 installed on the other side of the connecting frame 123 to the directly below of the telescopic tube 11. The operation is simple, reducing the difficulty and time cost of maintenance. When rotating the rotating rod 122, the limiting block 126 at its bottom rotates synchronously inside the housing 121. At this time, the limiting block 126 slides along the surface of the convex block 129, forcing the return spring 128 to be compressed. When the position of the connecting frame 123 is adjusted, at this time, under the elastic force of the return spring 128, the guiding frame 127 drives the convex block 129 to just abut against the depression on the surface of the limiting block 126, thus restricting the rotation of the rotating rod 122 and the connecting frame 123, ensuring a stable flow channel of dust inside the filtering component 12, and avoiding dust leakage or ineffective entry into the filter element 125 for filtration due to the offset of the position of the filter element 125. When the filter element 125 is working normally, the cutting equipment may generate vibrations, which may cause a slight displacement of the guiding frame 127. At this time, the nut on the outer side of the threaded column 120 can be rotated to press the guiding frame 127 towards the side close to the housing 121, avoiding the guiding frame 127 from shaking due to vibrations and ensuring the stability of its position.

[0042] The adsorption assembly 10 includes a mounting plate 101. A gas inlet housing 102 is fixedly connected to the outer side of the mounting plate 101. A centrifugal fan 103 is rotatably connected to the inner side of the gas inlet housing 102. A hose 104 is fixedly connected to the outer side of the gas inlet housing 102. The bottom end of the hose 104 is fixedly connected to an adsorption plate 105. A fixing member 106 is annularly arranged on the outer side of the gas inlet housing 102. The outer side of the mounting plate 101 is fixedly connected to the outer side of the protective housing 91. The outer side of the adsorption plate 105 is fixedly connected to the outer side of the dust collection housing 92. The end of the spline shaft 7 away from the hollow rotating shaft 6 is fixedly connected to the outer side of the centrifugal fan 103. The gas inlet housing 102 is fixed to the protective housing 91 through the mounting plate 101. At this time, the spline shaft 7 synchronously drives the centrifugal fan 103 in the gas inlet housing 102 to rotate. When the centrifugal fan 103 rotates, its blades rotate at high speed, causing the air in the gas inlet housing 102 to generate a centrifugal force. The air is quickly thrown to the outer side of the gas inlet housing 102, thereby forming a low-pressure area in the central area of the gas inlet housing 102. Since the adsorption plate 105 is connected to the gas inlet housing 102 through the hose 104 and the adsorption plate 105 is located near the cutting area, under the strong action of the low pressure in the central area of the gas inlet housing 102, the flue gas generated in the cutting area will quickly be sucked into the hose 104 through the pores on the adsorption plate 105 and then quickly enter the gas inlet housing 102 to prevent the diffusion of the flue gas. Subsequently, under the action of the centrifugal force, the flue gas will pass through the activated carbon cylinder 604 installed in the fixing member 106 on the outer side of the gas inlet housing 102. The activated carbon cylinder 604 can adsorb the harmful gases and odor molecules in the flue gas, achieving efficient purification treatment of the flue gas generated by cutting.

[0043] The fixing member 106 includes an annular fixing plate 601. A buffer spring 602 is fixedly connected to the top of the annular fixing plate 601. The top end of the buffer spring 602 is fixedly connected to an installation cylinder 603. An activated carbon cylinder 604 is movably installed inside the installation cylinder 603. A fixing cylinder 605 is slidably connected to the outer side of the installation cylinder 603. A cover plate 606 is threadedly connected to the top of the fixing cylinder 605. The bottom of the annular fixing plate 601 is fixedly connected to the outer side of the gas inlet housing 102. The inner side of the annular fixing plate 601 is fixedly connected to the outer side of the fixing cylinder 605. The bottom of the cover plate 606 is in contact with the top of the activated carbon cylinder 604. When the activated carbon cylinder 604 reaches the adsorption saturation state, the cover plate 606 at the top of the fixing cylinder 605 can be easily unscrewed. At this time, the elastic force of the buffer spring 602 is released and drives the installation cylinder 603 to move away from the annular fixing plate 601. At this time, the installation cylinder 603 can drive the activated carbon cylinder 604 to pop out of the fixing cylinder 605, so as to facilitate the removal and replacement of a new activated carbon cylinder 604, thereby continuously maintaining the excellent purification effect of the adsorption assembly 10 on the cutting flue gas, ensuring the cleanliness of the air in the working environment, and protecting the health of the operators.

[0044] Working principle:

[0045] During use, a fixed fixture can be installed on the fixture guide rail 2 at the top of the support table 1 to fix the accessories of the sewing machine. The fixture can slide along the surface of the fixture guide rail 2, facilitating the pushing of the fixed sewing machine accessories towards the side close to the disc saw blade 8. The height of the support plate 3 can be adjusted by rotating the bolt, thereby adjusting the height of the disc saw blade 8 relative to the support table 1.

[0046] During the cutting operation, the protective component 9 shields the cutting spatter. During this process, the suction fan 14 rotates together with the hollow rotating shaft 6, and the gas in the telescopic tube 11 and the protective component 9 is extracted through the filtering component 12, creating a negative pressure state inside the protective component 9. At this time, the dust collected and shielded by the protective component 9 can be adsorbed inside the filtering component 12 along the telescopic tube 11. Meanwhile, the adsorption component 10 can operate synchronously with the rotation of the spline shaft 7 to absorb the fumes generated during cutting.

[0047] Among them, a telescopic cylinder 15 is set to drive the protective component 9 and the spline shaft 7 to move. At this time, the spline shaft 7 can slide along the inner side of the hollow rotating shaft 6 while rotating with the hollow rotating shaft 6, thereby adjusting the position of the disc saw blade 8 relative to the mounting bracket 4, and further expanding the cutting range of the disc saw blade 8. At the same time, the telescopic tube 11 can contract synchronously with the movement of the protective component 9 to ensure that the inside of the protective component 9 is always in a negative pressure environment during cutting. In fact, the protective net 13 can protect the suction fan 14.

[0048] When the sewing machine accessories pass under the protective housing 91, the sewing machine accessories will push the dust collecting housing 92 upward, causing the guide rod 93 to slide upward along both sides of the protective housing 91, compressing the compression spring 94. At this time, under the elastic force of the compression spring 94, the dust collecting housing 92 can be pressed against the surface of the passing sewing machine accessories, reducing the diffusion of debris in the working area, keeping the working environment clean, and reducing the difficulty of subsequent cleaning work.

[0049] During this process, a negative pressure environment is always maintained inside the protective housing 91 and the dust collecting housing 92. The dust collected inside them will be sucked into the telescopic tube 11 and then enter the filtering component 12 for collection. The dust generated by cutting is promptly sucked in to prevent the dust from overflowing into the surrounding environment. The dust is promptly collected into the filtering component 12, avoiding the re-floating of the dust accumulated in the protective housing 91 and the dust collecting housing 92 due to equipment vibration and other reasons, which helps to maintain the cleanliness of the entire cutting equipment and its surrounding environment.

[0050] When dust enters the filter assembly 12, under the suction of the suction fan 14, the dust will be adsorbed on the surface of the filter element 125 in the clamping cylinder 124. After long-term use, when the adsorption capacity of the filter element 125 decreases, only need to rotate the rotating rod 122 to rotate the clamping cylinder 124 and the filter element 125 installed on the other side of the connecting frame 123 to the directly below of the telescopic pipe 11. The operation is simple, reducing the difficulty and time cost of maintenance.

[0051] When rotating the rotating rod 122, the limit block 126 at its bottom rotates synchronously within the outer shell 121. At this time, the limit block 126 slides along the surface of the convex block 129, forcing the return spring 128 to be compressed under force. When the position of the connecting frame 123 is adjusted, at this time, under the elastic force of the return spring 128, the guide frame 127 drives the convex block 129 to just abut against the depression on the surface of the limit block 126, thereby restricting the rotation of the rotating rod 122 and the connecting frame 123, ensuring a stable flow channel for dust within the filter assembly 12, and avoiding dust leakage or ineffective entry into the filter element 125 for filtration due to the offset of the filter element 125.

[0052] When the filter element 125 is working normally, the cutting equipment may generate vibrations, which may cause slight displacement of the guide frame 127. At this time, the nut outside the threaded column 120 can be rotated to press the guide frame 127 tightly against the side closer to the outer shell 121, avoiding the shaking of the guide frame 127 due to vibration and ensuring the stability of its position.

[0053] During this process, the air inlet housing 102 is fixed to the protective housing 91 through the mounting plate 101. At this time, the spline shaft 7 drives the centrifugal fan 103 within the air inlet housing 102 to rotate synchronously. When the centrifugal fan 103 rotates, its blades rotate at high speed, causing the air within the air inlet housing 102 to generate centrifugal force, and the air is quickly thrown to the outside of the air inlet housing 102, thereby forming a low-pressure area in the central region of the air inlet housing 102. Since the adsorption plate 105 is connected to the air inlet housing 102 through the hose 104 and the adsorption plate 105 is located near the cutting area, under the strong action of the low pressure in the central region of the air inlet housing 102, the fumes generated in the cutting area will quickly be sucked into the hose 104 through the pores on the adsorption plate 105, and then quickly enter the air inlet housing 102 to prevent the diffusion of fumes.

[0054] Subsequently, under the action of centrifugal force, the fumes will pass through the activated carbon cylinder 604 installed within the fixing component 106 on the outside of the air inlet housing 102. The activated carbon cylinder 604 can adsorb the harmful gases and odor molecules in the fumes, achieving efficient purification treatment of the fumes generated by cutting.

[0055] When the activated carbon cylinder 604 reaches the adsorption saturation state, the cover plate 606 at the top of the fixed cylinder 605 can be easily unscrewed. At this time, the elastic force of the buffer spring 602 is released, driving the installation cylinder 603 to move away from the annular fixing plate 601. At this time, the installation cylinder 603 can drive the activated carbon cylinder 604 to pop out of the fixed cylinder 605, facilitating the removal and replacement of the new activated carbon cylinder 604, so as to continuously maintain the excellent purification effect of the adsorption assembly 10 on the cutting flue gas, ensure the cleanliness of the air in the working environment, and protect the physical health of the operators.
