Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting devices, and particularly to a laser cutting device and a cutting method for processing agricultural machinery metal accessories. Background Technique

[0002] Laser cutting is an advanced processing technology that uses a high-power density laser beam to separate workpieces. Its principle is that the focused laser beam irradiates the material to be cut, causing it to quickly heat up to the vaporization temperature and evaporate to form holes. As the beam moves, the holes continuously form a very narrow cut, thereby realizing the cutting of the material. The cut is narrow, the surface roughness value of the cutting surface is low, the width of the heat-affected zone is small, the material properties near the cut are hardly affected, and the deformation is very small. The cutting accuracy is high, the geometric shape of the cut is good, and the laser cutting speed is much higher than that of traditional cutting methods, which can greatly improve production efficiency.

[0003] The patent with the publication number CN220807590U discloses a cutting device for processing agricultural machinery accessories, belonging to the field of cutting devices. A cutting device for processing agricultural machinery accessories includes a workbench. A water storage box is installed at the lower end of the workbench through a mounting plate. An electric push rod is installed at the lower end of the workbench. The output end of the electric push rod is installed with a mounting plate. A servo motor is installed at the upper end of the mounting plate. The output end of the servo motor is installed with a transmission shaft through a coupling. A cutting knife is installed on the side wall of the transmission shaft. A water storage tank is installed at the upper end of the workbench. A water pump is installed at the upper end of the water storage tank. Both the water inlet and the water outlet of the water pump are installed with conveying pipes. One of the conveying pipes extends into the water storage tank. It is convenient for cutting agricultural machinery accessories and convenient for spraying and flushing the generated smoke and debris during cutting, so as to facilitate the water to adsorb the smoke and debris. At the same time, it is convenient to cool the cut agricultural machinery accessories to prevent damage to the agricultural machinery accessories. During the use of the above device, the workpiece is not clamped and fixed. The unfixed workpiece is prone to vibration during cutting, which will cause the saw blade to jump during cutting, making the cutting surface rough. Therefore, a laser cutting device for processing agricultural machinery metal accessories is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a laser cutting device for processing agricultural machinery metal accessories in view of the above deficiencies in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a laser cutting device for processing agricultural machinery metal accessories, comprising a workbench, a clamping device is arranged on the top of the workbench, a cleaning device is arranged on the bottom of the workbench, a collecting device is arranged on the bottom of the workbench, and a cutting machine is arranged on the top of the workbench; the clamping device comprises a motor, a support plate 1, a concave plate, a clamping plate, a sliding plate, a pressing plate, a fixing rod, a push plate 1, a T-plate, and a reciprocating screw rod, the support plate 1 is fixedly connected to the bottom of the workbench, the motor is fixedly connected to the front of the support plate 1, and the concave plate is slidably connected to the front of the support plate 1. The clamping plate is connected to the inner wall of the workbench, and is fixedly connected to the rear of the concave plate. The clamping plate moves to clamp the workpiece. During the cutting process, if the workpiece is not effectively clamped, the workpiece is easily displaced under the force of the cutting tool. If the workpiece is not fixed well, even if it is just a slight shake, the laser cutting path will deviate from the preset track, resulting in a deviation in the cutting size, which cannot meet the processing accuracy requirements. By firmly fixing the workpiece by the clamping device, it can be ensured that the cutting tool is processed according to the predetermined path, so that the size and shape of the cut workpiece meet the design standards. The slide plate The top of the splint is fixedly connected, the pressure plate is slidably connected to the inner wall of the workbench, the fixed rod is fixedly connected to the top of the splint, the push plate 1 is fixedly connected to the top of the fixed rod, the T-plate is slidably connected to the top of the workbench, the reciprocating screw is fixedly connected to the output end of the motor, the bottom of the push plate 1 is slidably connected to the inner wall of the T-plate through a connecting rod, the right side of the sliding rod plate is slidably connected to the inner wall of the pressure plate through a connecting rod, the bottom of the splint is slidably connected to the top of the workbench, the support plate 1 is rotatably connected to the circumferential surface of the reciprocating screw, the concave plate is movably connected to the reciprocating screw, and the reciprocating screw is connected to the push plate 1 through the push plate 1. The sliding bar at the bottom of plate 1 drives the T-plate to move, so that the processed workpiece can be pushed out after cutting. After the workpiece cutting is completed, the processed workpiece can be easily pushed out, which helps to quickly clean the cutting work area and prepare for the processing of the next workpiece. The processed workpiece can be removed by the automatic ejection device, which can reduce the downtime of the equipment. Without this convenient ejection function, it will take time for manual labor to clean and move the workpiece after each cutting, which will greatly reduce production efficiency. Especially in the case of mass production, frequent manual cleaning will slow down the entire production process.

[0006] Preferably, the cleaning device includes a collection box, a scraping plate, a connecting plate, an elastic knocking rod, a convex plate, a second support plate, and a second pushing plate. The collection box is fixedly installed at the bottom of the workbench. The scraping plate is slidably connected to the inner wall of the workbench. The slag on the inner wall of the workbench is cleaned by the movement of the scraping plate. During the cutting process, especially in thermal cutting methods such as flame cutting and plasma cutting, slag will be generated. If the slag adheres to the cutting surface of the workpiece, it will affect the cutting size accuracy. When a numerical control cutting machine cuts a steel plate, the slag may accumulate at the cutting edge, causing a deviation between the actual size of the cut steel plate and the preset size. Timely cleaning of the slag can ensure the accurate size of the cut workpiece and meet the requirements of subsequent processing or use. The connecting plate is fixedly connected to the bottom of the scraping plate. The second support plate is fixedly connected to the front of the connecting plate. The elastic knocking rod is fixedly connected to the top of the second support plate. The convex plate is fixedly connected to the bottom of the workbench. The second pushing plate is fixedly connected to the bottom of the connecting plate. The top of the elastic knocking rod contacts the bottom of the convex plate. The circumferential surface of the reciprocating lead screw is rotatably connected to the inner wall of the collection box. The bottom of the second pushing plate contacts the inner wall of the collection box. The clamping plate is fixedly connected to the scraping plate. The movement of the second support plate drives the movement of the elastic knocking rod, so that the knocking rod contacts the convex plate when moving, causing the knocking rod to move up and down, making the effect of scraping the slag in the inner wall of the workbench better, making the cleaning cleaner, and facilitating the cutting machine to cut.

[0007] Preferably, the collecting device includes a concave block, a first guiding plate, a second guiding plate, a first rotating rod, a following block, and a friction plate. The concave block is fixedly connected to the top of the second pushing plate. The first guiding plate is fixedly connected to the top of the concave block. The second guiding plate is slidably connected to the inner wall of the collecting box. The first rotating rod is rotatably connected to the inner wall of the workbench through a torsion spring. The funnel is swung by the limitation of the first rotating rod to prevent material jamming during discharging. During the discharging process after the workpiece cutting is completed, if a material jamming phenomenon occurs, the entire production process will be forced to interrupt. In an automated metal cutting production line, workpieces are cut, discharged, and conveyed to the next processing link according to a certain rhythm and sequence. Once material jamming occurs, the subsequent workpieces cannot be discharged smoothly, which will cause the cutting equipment to idle and wait, and will also affect the normal operation of other processing equipment connected thereto, such as grinding and drilling equipment, thus causing the entire production process to stagnate and seriously affecting production efficiency. The following block is fixedly connected to the circumferential surface of the first rotating rod. The friction plate is in contact with the top of the workbench. The collecting device further includes a spring, a fixing plate, a roller, a second rotating rod, an activated carbon plate, a funnel, and a collecting box. The spring is fixedly connected to the left side of the friction plate. The fixing plate is fixedly connected to the top of the workbench. The roller is in contact with the friction plate. The second rotating rod is fixedly connected to the top of the roller. The activated carbon plate is fixedly connected to the circumferential surface of the second rotating rod. The funnel is fixedly connected to the circumferential surface of the first rotating rod. The left side of the collecting box is in contact with the right side of the workbench. The bottom of the friction plate is in contact with the top of the workbench. The outer wall of the funnel is in contact with the inner wall of the workbench. The left side of the second guiding plate is fixedly connected to the right side of the funnel. Since the activated carbon plate has a sufficient contact area, it can still effectively adsorb these increased harmful gases and maintain the stability of the purification effect. This is like a buffer pool with sufficient capacity, which can still stably process when the inflow rate changes.

[0008] A cutting method for a laser cutting device for processing agricultural machinery metal fittings includes the following steps: Step 1: Drive the reciprocating lead screw to rotate through a motor, drive the concave plate to move through the cross-shaped spiral groove on the reciprocating lead screw, and drive the clamping plate to move as the concave plate moves, and the clamping plate moves to clamp the workpiece. Step 2: Drive the sliding rod plate to move as the clamping plate moves, and drive the pressing plate to move up and down through the sliding rod inside the sliding rod plate as the sliding rod plate moves, and the pressing plate moves to squeeze both ends of the workpiece. Step 3: Drive the fixed rod to move as the clamping plate moves back and forth, and drive the first pushing plate to move as the fixed rod moves. Step 4: Drive the T-shaped plate to move through the sliding rod at the bottom of the first pushing plate, so as to push out the processed workpiece after the workpiece is cut.

[0009] Adopting the above technical solution, the present invention can bring the following beneficial effects: 1. The laser cutting device and cutting method for processing metal parts of agricultural machinery, through the cooperation between the motor, the support plate 1, the concave plate, the clamping plate, the slide plate, the pressure plate, the fixed rod, the push plate 1, the T-plate, and the reciprocating screw rod, the clamping plate moves to clamp the workpiece. In the process of cutting the workpiece, if the workpiece is not effectively clamped, the workpiece is easily displaced under the action of the cutting tool. If the workpiece is not fixed well, even if it is only a slight shake, the laser cutting path will deviate from the preset track, resulting in a deviation in the cutting size, and the processing accuracy requirement cannot be met. By firmly fixing the workpiece by the clamping device, it can be ensured that the cutting tool is processed according to the predetermined path, so that The size and shape of the cut workpiece meet the design standards. The T-plate is driven to move by the push plate and the bottom slide bar, which makes it easy to push out the processed workpiece after the workpiece is cut. After the workpiece is cut, the processed workpiece can be easily pushed out, which helps to quickly clean the cutting work area and prepare for the processing of the next workpiece. The processed workpiece is removed by the automatic ejection device, which can reduce the downtime of the equipment. Without this convenient ejection function, each time the cutting is completed, it will take time for manual cleaning and moving the workpiece, which will greatly reduce production efficiency. Especially in the case of mass production, frequent manual cleaning will make the entire production process slow.

[0010] 2. The laser cutting device and cutting method for processing agricultural machinery metal parts cooperate with each other through the collection box, scraper, connecting plate, elastic knocking rod, convex plate, support plate 2, and push plate 2. The scraper is driven to move through the clamping plate, and the slag on the inner wall of the workbench is cleaned by the movement of the scraper. In the cutting process, especially in thermal cutting methods such as flame cutting and plasma cutting, slag will be generated. If the slag adheres to the cutting surface of the workpiece, it will affect the accuracy of the cutting size. When the CNC cutting machine cuts the steel plate, the slag may accumulate on the cutting edge, causing the actual size of the steel plate after cutting to deviate from the preset size. Timely cleaning of the slag can ensure the accuracy of the workpiece size after cutting to meet the requirements of subsequent processing or use. The movement of the support plate 2 drives the elastic knocking rod to move, so that the knocking rod contacts the convex plate when moving, so that the knocking rod moves up and down. The slag in the inner wall of the workbench is better when scraped off, making the cleaning cleaner and facilitating cutting by the cutting machine.

[0011] 3. The laser cutting device and cutting method for agricultural machinery metal fittings cooperate with each other through the concave block, the first guide plate, the second guide plate, the first rotating rod, the follower block, the friction plate, the spring, the fixing plate, the roller, the second rotating rod, the activated carbon plate, the funnel, and the collection box. The funnel is swung by the limit of the first rotating rod to prevent material jamming during discharging. During the discharging process after the workpiece cutting is completed, if material jamming occurs, the entire production process will be forced to interrupt. In an automated metal cutting production line, workpieces are cut, discharged, and conveyed to the next processing link according to a certain rhythm and sequence. Once material jamming occurs, subsequent workpieces cannot be discharged smoothly, which will cause the cutting equipment to idle and wait, and will also affect the normal operation of other processing equipment connected thereto, such as grinding and drilling equipment, thus causing the entire production process to stagnate and seriously affecting production efficiency. When the cutting speed suddenly increases, resulting in an increase in the concentration of harmful gas generation, due to the sufficient contact area of the activated carbon plate, it can still effectively adsorb these increased harmful gases and maintain the stability of the purification effect. This is like a buffer pool with sufficient capacity, which can still be stably processed when the influent flow rate changes. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1 - 7An embodiment of the present invention is: a laser cutting device for processing agricultural machinery metal parts, including a workbench 1, a clamping device 2 is arranged on the top of the workbench 1, a cleaning device 3 is arranged on the bottom of the workbench 1, a collecting device 4 is arranged on the bottom of the workbench 1, and a cutting machine 5 is arranged on the top of the workbench 1; the clamping device 2 includes a motor 201, a support plate 202, a concave plate 203, a clamping plate 204, a sliding plate 205, a pressing plate 206, a fixing rod 207, a push plate 208, a T-plate 209, and a reciprocating screw rod 210, the support plate 202 is fixedly connected to the bottom of the workbench 1, the motor 201 is fixedly connected to the front of the support plate 202, the concave plate 203 is slidably connected to the inner wall of the workbench 1, and the clamping plate 204 is fixedly connected to the concave plate At the rear of 203, when the device is started, the reciprocating screw 210 is driven to rotate by the motor 201, and the concave plate 203 is driven to move by the cross-type spiral groove on the reciprocating screw 210, and the concave plate 203 moves to drive the clamping plate 204 to move, and the clamping plate 204 moves to clamp the workpiece. During the cutting process of the workpiece, if the workpiece is not effectively clamped, the workpiece is easily displaced under the action of the cutting tool. If the workpiece is not fixed well, even if it is just a slight shake, the laser cutting path will deviate from the preset track, resulting in a deviation in the cutting size, which cannot meet the processing accuracy requirements. By firmly fixing the workpiece by the clamping device 2, it can be ensured that the cutting tool is processed according to the predetermined path, so that the size and shape of the cut workpiece meet the design standards. The movement of the clamping plate 204 drives the sliding plate 205 to move. The movement of the sliding plate 205 drives the pressing plate 206 to move up and down through the sliding rod inside the sliding plate 205. The pressing plate 206 moves to squeeze the two ends of the workpiece, so that when the workpiece is cut, when the two ends of the workpiece are compacted and clamped, the bending moment caused by the cutting force can be effectively resisted during the cutting process. If only one end is fixed for cutting, the force applied by the cutting tool will cause the workpiece to bend at the unfixed end, resulting in a non-vertical cutting surface and reduced dimensional accuracy. The compaction and clamping at both ends can evenly distribute the cutting force, so that the pipe maintains a stable shape during cutting, ensuring that the size and shape after cutting meet the design requirements. The sliding plate 205 is fixedly connected to the top of the clamping plate 204, and the pressing plate 206 is slidably connected to the workbench 1 The inner wall of the clamping plate 204 is fixedly connected with the top of the clamping plate 204, the push plate 208 is fixedly connected to the top of the clamping plate 207, the T-plate 209 is slidably connected to the top of the workbench 1, and the reciprocating screw 210 is fixedly connected to the output end of the motor 201. The bottom of the push plate 208 is slidably connected to the inner wall of the T-plate 209 through a connecting rod, and the right side of the sliding rod plate 205 is slidably connected to the inner wall of the pressure plate 206 through a connecting rod. The bottom of the clamping plate 204 is slidably connected to the top of the workbench 1, the support plate 202 is rotatably connected to the circumferential surface of the reciprocating screw 210, and the concave plate 203 is movably connected to the reciprocating screw 210. The movement of the clamping plate 204 when opening and reciprocating drives the fixed rod 207 to move, and the movement of the fixed rod 207 drives the push plate 208 to move.The movement of the T-shaped plate 209 is driven by the sliding rod at the bottom of the first push plate 208, which facilitates the pushing out of the processed workpiece after cutting. After the workpiece cutting is completed, the processed workpiece can be conveniently pushed out, which helps to quickly clean the cutting work area and prepare for the processing of the next workpiece. Removing the processed workpiece through the automatic pushing device can reduce the downtime of the equipment. Without such a convenient pushing function, it takes time for workers to clean and carry the workpiece manually after each cutting, which will greatly reduce the production efficiency. Especially in the case of mass production, frequent manual cleaning will slow down the entire production process.

[0016] The cleaning device 3 includes a collection box 301, a scraper 302, a connecting plate 303, an elastic knocking rod 304, a convex plate 305, a second support plate 306, and a second push plate 307. The collection box 301 is fixedly installed at the bottom of the workbench 1. The scraper 302 is slidably connected to the inner wall of the workbench 1. The connecting plate 303 is fixedly connected to the bottom of the scraper 302. The movement of the scraper 302 is driven by the clamping plate 204. The slag on the inner wall of the workbench 1 is cleaned by the movement of the scraper 302. During the cutting process, especially in thermal cutting methods such as flame cutting and plasma cutting, slag will be generated. If the slag adheres to the cutting surface of the workpiece, it will affect the cutting size accuracy. When the numerical control cutting machine 5 cuts the steel plate, the slag may accumulate on the cutting edge, causing a deviation between the actual size of the cut steel plate and the preset size. Timely cleaning of the slag can ensure the accurate size of the cut workpiece and meet the requirements of subsequent processing or use. The second support plate 306 is fixedly connected to the front of the connecting plate 303. The elastic knocking rod 304 is fixedly connected to the top of the second support plate 306. The convex plate 305 is fixedly connected to the bottom of the workbench 1. The second push plate 307 is fixedly connected to the bottom of the connecting plate 303. The top of the elastic knocking rod 304 contacts the bottom of the convex plate 305. The circumferential surface of the reciprocating lead screw 210 is rotatably connected to the inner wall of the collection box 301. The bottom of the second push plate 307 contacts the inner wall of the collection box 301. The clamping plate 204 is fixedly connected to the scraper 302. The movement of the connecting plate 303 is driven by the movement of the scraper 302. The movement of the connecting plate 303 drives the movement of the second push plate 307. The movement of the second push plate 307 pushes the fallen slag to the other side, increasing the usable area of the collection box 301. The movement of the connecting plate 303 drives the movement of the second support plate 306. The movement of the second support plate 306 drives the movement of the elastic knocking rod 304, causing the elastic knocking rod 304 to contact the convex plate 305 when moving, so that the elastic knocking rod 304 moves up and down to better scrape the slag in the inner wall of the workbench 1, making the cleaning cleaner and facilitating the cutting of the cutting machine 5.

[0017] Working principle: When the device is started, the reciprocating screw 210 is driven to rotate by the motor 201, and the concave plate 203 is driven to move by the cross-type spiral groove on the reciprocating screw 210, and the concave plate 203 moves to drive the clamping plate 204 to move, and the clamping plate 204 moves to clamp the workpiece. During the cutting process, if the workpiece is not effectively clamped, the workpiece is easily displaced under the force of the cutting tool. If the workpiece is not fixed well, even if it is only a slight shake, the laser cutting path will deviate from the preset track, resulting in the cutting size. Deviation cannot meet the processing accuracy requirement, and by firmly fixing the workpiece by the clamping device 2, it can be ensured that the cutting tool is processed according to the predetermined path, so that the size and shape of the cut workpiece meet the design standard, the movement of the clamping plate 204 drives the sliding plate 205 to move, and the movement of the sliding plate 205 drives the pressing plate 206 to move up and down through the sliding rod inside the sliding plate 205, and the movement of the pressing plate 206 squeezes the two ends of the workpiece, so that when the workpiece is cut, when the two ends of the workpiece are compacted and clamped, the bending moment caused by the cutting force can be effectively resisted during the cutting process. If only one end is fixed for cutting, the force applied by the cutting tool will cause the workpiece to bend at the unfixed end, resulting in a non-vertical cutting surface and reduced dimensional accuracy. Compacting and clamping at both ends can evenly distribute the cutting force, so that the pipe maintains a stable shape during cutting, ensuring that the size and shape after cutting meet the design requirements. The movement of the clamping plate 204 during opening and reciprocating movement drives the fixing rod 207 to move, and the movement of the fixing rod 207 drives the push plate 208 to move. The T-plate 209 is driven to move by the bottom slide bar and the inclined groove of the push plate 208, so that the processed workpiece can be pushed out after the workpiece is cut. After the workpiece is cut, the processed workpiece can be easily pushed out, which helps to quickly clean the cutting work area and prepare for the processing of the next workpiece. The processed workpiece can be removed by the automatic ejection device, which can reduce the downtime of the equipment. If there is no such convenient ejection function, it takes time for manual labor to clean and move the workpiece after each cutting, which greatly reduces production efficiency. Especially in the case of mass production, frequent manual cleaning will slow down the entire production process.

[0018] Drive the scraper 302 to move through the clamping plate 204, and clean the slag on the inner wall of the workbench 1 by the movement of the scraper 302. During the cutting process, especially for thermal cutting methods such as flame cutting and plasma cutting, slag will be generated. If the slag adheres to the cutting surface of the workpiece, it will affect the cutting dimension accuracy. When the CNC cutting machine 5 cuts the steel plate, the slag may accumulate on the cutting edge, causing a deviation between the actual size of the cut steel plate and the preset size. Timely cleaning of the slag can ensure the accurate size of the cut workpiece and meet the requirements of subsequent processing or use. Drive the connecting plate 303 to move by the movement of the scraper 302, drive the second push plate 307 to move by the movement of the connecting plate 303, and push the fallen slag to the other side by the movement of the second push plate 307, so as to increase the usable area of the collection box 301. Drive the second support plate 306 to move by the movement of the connecting plate 303, and drive the elastic knocking rod 304 to move by the movement of the second support plate 306, so that the elastic knocking rod 304 contacts the convex plate 305 when moving, and the elastic knocking rod 304 moves up and down to make the slag in the inner wall of the workbench 1 have a better scraping effect, making the cleaning cleaner and facilitating the cutting machine 5 to cut.

[0019] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, the collecting device 4 includes a recessed block 401, a first guiding plate 402, a second guiding plate 403, a first rotating rod 404, a follower block 405, and a friction plate 406. The recessed block 401 is fixedly connected to the top of the second pushing plate 307. The first guiding plate 402 is fixedly connected to the top of the recessed block 401. The second guiding plate 403 is slidably connected to the inner wall of the collecting box 301. The first rotating rod 404 is rotatably connected to the inner wall of the workbench 1 through a torsion spring. When the second pushing plate 307 moves, it drives the recessed block 401 to move. When the recessed block 401 moves, it drives the first guiding plate 402 to move. When the first guiding plate 402 moves, it will contact the second guiding plate 403, causing the second guiding plate 403 to move to the left. The second guiding plate 403 moving to the left drives the funnel 412 to move to the left. The funnel 412 is limited by the first rotating rod 404 to swing, preventing material jamming during discharging. During the discharging process after the workpiece cutting is completed, if a material jamming phenomenon occurs, the entire production process will be forced to interrupt. In an automated metal cutting production line, workpieces are cut, discharged, and transported to the next processing link according to a certain rhythm and sequence. Once material jams, subsequent workpieces cannot be discharged smoothly, resulting in the cutting equipment idling and waiting, and also affecting the normal operation of other processing equipment connected thereto, such as grinding and drilling equipment, thus causing the entire production process to stagnate and seriously affecting production efficiency. The follower block 405 is fixedly connected to the circumferential surface of the first rotating rod 404. The friction plate 406 contacts the top of the workbench 1. The collecting device 4 further includes a spring 407, a fixing plate 408, a roller 409, a second rotating rod 410, an activated carbon plate 411, a funnel 412, and a collecting box 413. The spring 407 is fixedly connected to the left side of the friction plate 406. The fixing plate 408 is fixedly connected to the top of the workbench 1. The roller 409 contacts the friction plate 406. The second rotating rod 410 is fixedly connected to the top of the roller 409. The activated carbon plate 411 is fixedly connected to the circumferential surface of the second rotating rod 410. The funnel 412 is fixedly connected to the circumferential surface of the first rotating rod 404. The left side of the collecting box 413 contacts the right side of the workbench 1. The bottom of the friction plate 406 contacts the top of the workbench 1. The outer wall of the funnel 412 contacts the inner wall of the workbench 1. The left side of the second guiding plate 403 is fixedly connected to the right side of the funnel 412. The funnel 412 swings to enable the workpiece to enter the collecting box 413 for collection. At the same time, the first rotating rod 404 rotates to drive the follower block 405 to rotate. When the follower block 405 rotates, it contacts the friction plate 406, causing the friction plate 406 to move to the left. The friction plate 406 moving to the left drives the roller 409 to rotate. The roller 409 rotating drives the second rotating rod 410 to rotate. The second rotating rod 410 rotating drives the activated carbon plate 411 to rotate. The rotation of the activated carbon plate 411 increases the contact area between the activated carbon plate 411 and the air. During the cutting operation process, the generation concentration of harmful gases may vary due to factors such as cutting materials, cutting speeds, and cutting processes. A larger activated carbon contact area can better cope with this change.When the cutting speed suddenly increases, resulting in an increase in the concentration of harmful gases generated, due to the sufficient contact area of the activated carbon plate 411, it can still effectively adsorb these increased harmful gases and maintain the stability of the purification effect. This is like a buffer pool with sufficient capacity that can still be stably processed when the influent flow rate changes.

[0020] A cutting method for a laser cutting device used in the processing of agricultural machinery metal fittings, comprising the following steps: Step 1: Drive the reciprocating lead screw 210 to rotate through the motor 201, drive the concave plate 203 to move through the cross-type spiral groove on the reciprocating lead screw 210, and drive the clamping plate 204 to move when the concave plate 203 moves, and clamp the workpiece when the clamping plate 204 moves; Step 2: Drive the slide bar plate 205 to move when the clamping plate 204 moves, drive the pressure plate 206 to move up and down through the slide bar inside the slide bar plate 205 when the slide bar plate 205 moves, and extrude both ends of the workpiece when the pressure plate 206 moves; Step 3: Drive the fixed rod 207 to move by the movement of the clamping plate 204 when it reciprocates, and drive the first push plate 208 to move when the fixed rod 207 moves; Step 4: Drive the T-shaped plate 209 to move through the slide bar at the bottom of the first push plate 208, facilitating the ejection of the processed workpiece after cutting.

[0021] Working principle: The depression block 401 is driven to move by the movement of the pusher plate two 307. When the depression block 401 moves, it drives the guide plate one 402 to move. When the guide plate one 402 moves, it will contact the guide plate two 403, causing the guide plate two 403 to move to the left. The guide plate two 403 moving to the left drives the funnel 412 to move to the left. The funnel 412 is limited by the rotating rod one 404 to swing, preventing material jamming during discharging. During the discharging process after the workpiece cutting is completed, if a material jamming phenomenon occurs, the entire production process will be forced to interrupt. In an automated metal cutting production line, workpieces are cut, discharged, and transported to the next processing link according to a certain rhythm and sequence. Once material jamming occurs, subsequent workpieces cannot be discharged smoothly, resulting in the cutting equipment idling and waiting, and it will also affect the normal operation of other processing equipment connected to it, such as grinding and drilling equipment, thus causing the entire production process to stagnate and seriously affecting production efficiency. The workpiece enters the collection box 413 for collection through the swinging of the funnel 412. At the same time, the rotating rod one 404 rotates to drive the follower block 405 to rotate. When the follower block 405 rotates, it contacts the friction plate 406, causing the friction plate 406 to move to the left. The friction plate 406 moving to the left drives the roller 409 to rotate. The roller 409 rotating drives the rotating rod two 410 to rotate. The rotating rod two 410 rotating drives the activated carbon plate 411 to rotate. The rotation of the activated carbon plate 411 increases the contact area between the activated carbon plate 411 and the air. During the cutting operation process, the generation concentration of harmful gases may vary due to factors such as cutting materials, cutting speed, and cutting process. A larger activated carbon contact area can better cope with this change. When the cutting speed suddenly increases, resulting in an increase in the generation concentration of harmful gases, due to the sufficient contact area of the activated carbon plate 411, it can still effectively adsorb these increased harmful gases and maintain the stability of the purification effect. This is like a buffer pool with sufficient capacity that can still be stably processed when the inflow rate changes.
