Description

Technical Field

[0001] This invention belongs to the field of metal sheet cutting technology, specifically relating to a metal sheet cutting device and its usage method. Background Technology

[0002] Metal sheet cutting equipment is a type of equipment used for cutting and processing metal sheets. It is mainly used for cutting, drilling, grooving and other processing of metal sheets. Common metal sheet cutting equipment includes circular saw cutting equipment, CNC plasma cutting equipment and laser cutting equipment. Among them, circular saw cutting equipment is more widely used due to its advantages of low operating cost and simple equipment structure.

[0003] Common circular saw-type metal sheet cutting equipment mainly consists of a cutting worktable, a drive unit, a circular saw cutting blade, and other auxiliary accessories. In actual application, the metal sheet to be cut is placed on the cutting worktable, and the circular saw cutting blade is rotated by the drive unit to achieve the cutting of the metal sheet.

[0004] In order to ensure the accuracy of cutting, conventional circular saw-type metal sheet cutting equipment mainly uses additional clamping and positioning components to clamp and fix the metal sheet to be cut. Although this method can improve the cutting accuracy of the metal sheet, in actual application, it cannot independently clamp and transport the cut product and waste according to the processing needs. This not only makes the unloading process of the cut metal sheet cumbersome and complicated, but also causes scratches to the metal sheet due to the friction of the chips during the sliding unloading process. As a result, the convenience and efficiency of cutting metal sheets are poor.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a metal sheet cutting device and its usage method, which can improve the convenience and efficiency of cutting and processing metal sheets.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] A metal sheet cutting device includes: a cutting machine housing, a split clamping and limiting mechanism, a dust suppression and collection mechanism, and a pair of cleaning and positioning mechanisms.

[0009] The split clamping and limiting mechanism is mounted on the top of the cutting machine housing. The split clamping and limiting mechanism includes a guide frame, which is fixedly mounted on the top of the cutting machine housing. Multiple sets of evenly distributed supporting conveying rollers are rotatably mounted inside the guide frame. A pair of symmetrically distributed clamping and positioning plates are arranged above the multiple sets of supporting conveying rollers. A pair of supporting base plates are fixedly mounted on the side of each pair of clamping and positioning plates close to the supporting conveying rollers. A lifting and retracting assembly is fixedly mounted below the pair of clamping and positioning plates.

[0010] The dust suppression and dust collection mechanism is mounted on the outside of multiple sets of supporting conveyor rollers. The dust suppression and dust collection mechanism includes a dust collection liquid tank, which is arranged below the multiple sets of supporting conveyor rollers. A filter plate is slidably mounted inside the dust collection liquid tank. Purification guide pipes are evenly distributed on both sides of the dust collection liquid tank. A circulating cooling and dust suppression component is fixedly connected to one end of the purification guide pipe located outside the cutting machine box.

[0011] A pair of the cleaning and positioning mechanisms are fixedly assembled inside the cutting machine housing. The cleaning and positioning mechanisms are used to assist in cleaning multiple sets of supporting conveyor rollers and to assist in supporting and positioning the metal sheet.

[0012] In one or more embodiments of the present invention, an assembly gantry is slidably mounted on top of the cutting machine housing. The assembly gantry serves to limit the assembly and allow horizontal movement of the lifting connecting rod. The lifting connecting rod is slidably mounted on the side of the assembly gantry close to the cutting machine housing. The lifting connecting rod provides horizontal movement and lifting control for the protective cover. The lower end of the lifting connecting rod is fixedly connected to the protective cover. The protective cover provides assembly limitation and cutting protection for the cutting disc.

[0013] In one or more embodiments of the present invention, a cutting disc is rotatably mounted inside the protective cover. The metal sheet is cut by the rotation of the cutting disc. A cutting motor is fixedly mounted on one side of the protective cover, and the output shaft of the cutting motor is drively connected to the cutting disc. The cutting motor provides power, and the rotation of the cutting disc is driven by controlling the operation of the cutting motor.

[0014] In one or more embodiments of the present invention, the lifting and retracting assembly includes a pair of lifting cylinders. The extension and retraction states of the cylinder piston rods are controlled by controlling the air intake state of the pair of lifting cylinders, thereby facilitating the adjustment of the lifting state of the base frame. Each pair of lifting cylinders has a cylinder piston rod slidably mounted inside it. The cylinder piston rods support and fix the base frame while allowing it to move vertically. The end of the cylinder piston rod located outside the lifting cylinder is fixedly mounted to the base frame. The base frame provides assembly and limiting functions for the movable connecting frame, the pair of guide rods, and the threaded rod.

[0015] In one or more embodiments of the present invention, a slide rail is fixedly mounted on the upper part of the base frame, and a pair of sliders are slidably mounted on the upper part of the slide rail. The cooperation between the slide rail and the sliders serves to limit the assembly and guide the sliding of the movable connecting frame. A movable connecting frame is fixedly mounted on the upper part of each pair of sliders, and the movable connecting frame is fixedly connected to the bottom of the clamping positioning plate. The movable connecting frame provides support, fixation, and movement control for the clamping positioning plate.

[0016] In one or more embodiments of the present invention, a pair of guide rods are fixedly mounted inside the base frame, and both of the movable connecting frames are slidably engaged with the guide rods. The sliding engagement between the guide rods and the movable connecting frames provides sliding guidance for the movable connecting frames. A threaded rod is provided between the pair of guide rods, and a pair of external threads with opposite rotation directions are formed on the outer side of the threaded rod. Both of the movable connecting frames are threadedly connected to the threaded rod. The mutual engagement of the internal and external threads allows the pair of movable connecting frames to move in opposite directions as the threaded rod rotates, thereby facilitating the clamping and fixing of the pair of clamping and positioning plates on the material to be cut.

[0017] In one or more embodiments of the present invention, a drive pulley is fixedly mounted on the outer side of the threaded rod, and the drive pulley is arranged between a pair of movable connecting frames. The rotation of the drive pulley drives the threaded rod to rotate, thereby facilitating the clamping and fixing of a pair of clamping and positioning plates for the material to be cut. A synchronous belt is fitted on the outer side of the drive pulley. The synchronous belt connects the drive pulley and the transmission pulley, allowing the drive pulley to rotate synchronously with the transmission pulley under the action of the synchronous belt. A transmission pulley is fitted on the side of the synchronous belt opposite to the threaded rod. The transmission pulley transmits power to the drive motor. A drive motor is fixedly mounted below the base frame, and the output shaft of the drive motor is connected to the transmission pulley. The drive motor provides power, and the rotation of the transmission pulley is driven by controlling the operation of the drive motor. A dust cover is fixedly connected between the pair of movable connecting frames. The dust cover protects the threaded rod from dust.

[0018] In one or more embodiments of the present invention, a pair of cleaning handles are fixedly mounted on top of the filter plate. The filter plate is moved by applying force to the cleaning handles, thereby facilitating the filtration of impurities collected in the collection tank. The circulating cooling and dust suppression assembly includes a pair of dust filter cartridges, symmetrically arranged on both sides of the cutting machine housing. The pair of dust filter cartridges provide filtration and flow control for the air supplied by the exhaust duct. A flow guide hood is fixedly connected to both the pair of dust filter cartridges and the purification flow guide duct. The flow guide hood connects the dust filter cartridges and the purification flow guide duct. An exhaust fan is fixedly mounted inside the flow guide hood. The air inside the dust filter cartridges is continuously exhausted by controlling the operation of the exhaust fan.

[0019] In one or more embodiments of the present invention, a fixed base plate is threadedly fitted to the bottom of the dust filter cartridge. The fixed base plate serves to limit the assembly of the inner filter cartridge. The inner filter cartridge is fixedly connected to one side of the fixed base plate inside the dust filter cartridge. The air delivered by the exhaust pipe is filtered through the inner filter cartridge. The inner filter cartridge divides the dust filter cartridge into a dust filtration chamber and an exhaust chamber. The guide hood is connected to the exhaust chamber, and an exhaust pipe is connected between each pair of dust filter cartridges and the protective cover. The exhaust pipe is connected to the dust filtration chamber. The exhaust pipe serves to connect the dust filter cartridge and the purification guide pipe, facilitating the collection and diversion of waste gas and some chips generated during the cutting process of the cutting disc.

[0020] A method of using a metal sheet cutting device includes the following steps:

[0021] S1. Before use, the surface of multiple sets of support conveyor rollers can be cleaned by controlling the operation of the cleaning and positioning mechanism to prevent impurities from adhering to the surface of the support conveyor rollers, which may cause scratches on the plate to be cut and affect the positioning deviation. After cleaning, the cleaning and positioning mechanism is reset. Then, the plate to be cut can be placed on multiple sets of support conveyor rollers. The rotation of multiple sets of support conveyor rollers can support and roll the plate to be cut.

[0022] S2. When the material to be cut is moved below the cutting disc, the drive motor can be controlled to drive the transmission pulley to rotate. The threaded rod rotates under the action of the drive pulley, the synchronous belt and the transmission pulley. A pair of movable connecting frames can move in opposite directions with the rotation of the threaded rod under the action of the internal and external threads. The material to be cut is clamped by driving a pair of clamping and positioning plates to move. The bottom surface of the material to be cut can be supported by the supporting base plate.

[0023] S3. At the same time, the clamping and positioning plate can be lifted by controlling the extension of a pair of cylinder piston rods, thereby supporting and clamping the metal sheet to be cut. Then, the metal sheet can be cut by rotating and moving the cutting disc. The sheet falling during the cutting process can be supported and independently conveyed by multiple sets of supporting conveying rollers, thus achieving the purpose of step-by-step conveying of metal sheet and waste.

[0024] S4. In addition, the adsorption and purification liquid can be collected and stored in the collection tank. During the cutting process of the cutting disc cutting the metal sheet, the chips that fall off can be collected by the collection tank, avoiding the adverse effects of the chips on the subsequent transportation and positioning of the metal sheet and waste.

[0025] S5. Furthermore, the air in the exhaust chamber can be continuously extracted and transported by controlling the operation of the exhaust fan, so that the exhaust gas and some chips generated during the rotation cutting process of the cutting disc can be transported to the filter chamber along the air duct under the action of the airflow, and the impurities contained in the airflow can be filtered by the inner filter screen.

[0026] S6. The filtered exhaust gas can be transported to the exhaust pipe along the purification guide pipe, and purified by the adsorption purification liquid. The purified gas can be transported from bottom to top along the impurity collection tank. The exhaust gas and chips generated during the cutting process of the cutting disc can be further collected and treated by the continuous airflow.

[0027] Compared with the prior art, the present invention, by setting up a split clamping and limiting mechanism and a dust suppression and collection mechanism, can independently transport the metal sheet and waste generated during the cutting process, simplifying the unloading process of the metal sheet, greatly reducing the adverse effects of chips on the metal sheet cutting process, and significantly improving the convenience and efficiency of cutting and processing metal sheets.

[0042] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0043] like Figures 1 to 11 As shown, a metal sheet cutting device according to one embodiment of the present invention includes: a cutting machine housing 1, a split clamping and limiting mechanism 2, a dust suppression and collection mechanism 3, and a pair of cleaning and positioning mechanisms 4.

[0044] like Figures 1 to 4 As shown, an assembly gantry 101 is slidably mounted on top of the cutting machine housing 1. The assembly gantry 101 serves to limit the assembly and allow the horizontal movement of the lifting connecting rod 102.

[0045] like Figures 1 to 4 As shown, a lifting connecting rod 102 is slidably mounted on the side of the gantry frame 101 close to the cutting machine housing 1. The lifting connecting rod 102 controls the horizontal movement and lifting of the protective cover 103. The lower end of the lifting connecting rod 102 is fixedly connected to the protective cover 103. The protective cover 103 provides assembly limit and cutting protection for the cutting disc 104.

[0046] like Figures 1 to 4 As shown, a cutting disc 104 is rotatably mounted inside the protective cover 103. The metal sheet is cut by rotating the cutting disc 104.

[0047] like Figures 1 to 4 As shown, a cutting motor 105 is fixedly mounted on one side of the protective cover 103, and the output shaft of the cutting motor 105 is connected to the cutting disc 104. The cutting motor 105 provides power, and the cutting disc 104 is rotated by controlling the operation of the cutting motor 105.

[0048] like Figure 2 As shown, the split-type clamping and limiting mechanism 2 is mounted on top of the cutting machine housing 1. The split-type clamping and limiting mechanism 2 includes a guide frame 201, which is fixedly mounted on top of the cutting machine housing 1. The guide frame 201 serves to limit the assembly of multiple sets of supporting conveyor rollers 202.

[0049] like Figure 2 As shown, multiple sets of evenly distributed support and conveying rollers 202 are rotatably assembled inside the guide frame 201. The multiple sets of support and conveying rollers 202 can support, limit, and roll the metal sheet.

[0050] Specifically, in practical applications, each of the multiple sets of supporting conveyor rollers 202 is fixedly connected to a sprocket at one end outside the guide frame 201, and a chain is engaged on the outer side of the multiple sets of sprockets. Through the cooperation of the sprockets and the chain, the multiple sets of supporting conveyor rollers 202 can be driven to rotate synchronously.

[0051] In addition, a geared motor is fixedly mounted on one side of the guide frame 201, and the output shaft of the geared motor is connected to the transmission of a single supporting conveyor roller 202.

[0052] like Figures 1 to 2As shown, a pair of symmetrically distributed clamping and positioning plates 203 are arranged above multiple sets of supporting conveyor rollers 202. The metal sheet is clamped and fixed by the cooperation of the pair of clamping and positioning plates 203. A pair of supporting base plates 204 are fixedly installed on the side of each pair of clamping and positioning plates 203 close to the supporting conveyor rollers 202. The pair of supporting base plates 204 support and limit the bottom of the metal sheet, which facilitates the subsequent lifting and limiting of the metal sheet.

[0053] like Figures 2 to 3 As shown, a lifting and retracting assembly is fixedly mounted below a pair of clamping and positioning plates 203. The lifting and retracting assembly includes a pair of lifting cylinders 205. The extension and retraction states of the cylinder piston rods 206 are controlled by controlling the air intake state of the pair of lifting cylinders 205, thereby facilitating the adjustment of the lifting state of the base frame 207.

[0054] like Figures 2 to 3 As shown, each of the pair of lifting cylinders 205 has a cylinder piston rod 206 slidably mounted inside it. The cylinder piston rod 206 serves to support and fix the base frame 207 and to allow it to move up and down.

[0055] like Figures 2 to 3 As shown, a base frame 207 is fixedly mounted on one end of the cylinder piston rod 206 outside the lifting cylinder 205. The base frame 207 serves to limit the assembly of the movable connecting frame 210, a pair of guide rods 211 and threaded rod 212.

[0056] like Figures 2 to 3 As shown, a slide rail 208 is fixedly mounted on the upper part of the base frame 207, and a pair of sliders 209 are slidably mounted on the upper part of the slide rail 208. The cooperation between the slide rail 208 and the sliders 209 serves to limit the assembly and guide the sliding of the movable connecting frame 210.

[0057] like Figures 2 to 3 As shown, a movable connecting frame 210 is fixedly mounted above each pair of sliders 209, and the movable connecting frame 210 is fixedly connected to the bottom of the clamping and positioning plate 203. The movable connecting frame 210 serves to support, fix, and control the movement of the clamping and positioning plate 203.

[0058] like Figures 2 to 3 As shown, a pair of guide rods 211 are fixedly mounted inside the base frame 207, and a pair of movable connecting frames 210 are slidably engaged with the guide rods 211. The sliding engagement between the guide rods 211 and the movable connecting frames 210 serves to guide the sliding of the movable connecting frames 210.

[0059] like Figures 2 to 3As shown, a threaded rod 212 is arranged between a pair of guide rods 211. A pair of external threads with opposite rotation directions are formed on the outer side of the threaded rod 212, and a pair of movable connecting frames 210 are threadedly connected to the threaded rod 212. The mutual engagement of the internal and external threads allows the pair of movable connecting frames 210 to move in opposite directions as the threaded rod 212 rotates, thus facilitating the clamping and fixing of a pair of clamping and positioning plates 203 onto the material to be cut.

[0060] like Figures 6 to 7 As shown, a drive pulley 213 is fixedly mounted on the outer side of the threaded rod 212, and the drive pulley 213 is arranged between a pair of movable connecting frames 210. The rotation of the drive pulley 213 drives the threaded rod 212 to rotate, thereby facilitating the driving of a pair of clamping and positioning plates 203 to clamp and fix the material to be cut.

[0061] like Figures 6 to 7 As shown, a synchronous belt 214 is fitted on the outer side of the drive pulley 213. The synchronous belt 214 serves to connect the drive pulley 213 and the transmission pulley 215, so that the drive pulley 213 can rotate synchronously with the transmission pulley 215 under the action of the synchronous belt 214.

[0062] like Figures 6 to 7 As shown, a transmission pulley 215 is fitted onto the side of the synchronous belt 214 opposite to the threaded rod 212. The transmission pulley 215 transmits power to the drive motor 216. The drive motor 216 is fixedly mounted below the base frame 207, and the output shaft of the drive motor 216 is connected to the transmission pulley 215. The drive motor 216 provides power, and the operation of the drive motor 216 drives the transmission pulley 215 to rotate.

[0063] like Figures 6 to 7 As shown, a dust cover 217 is fixedly connected between a pair of movable connecting brackets 210. The dust cover 217 serves to protect the threaded rod 212 from dust.

[0064] like Figures 9 to 10 As shown, the dust suppression and collection mechanism 3 is assembled on the outside of multiple sets of supporting conveyor rollers 202. The dust suppression and collection mechanism 3 includes a collection liquid tank 301, which is arranged below the multiple sets of supporting conveyor rollers 202. The collection liquid tank 301 is used to collect and store the adsorbed and purified liquid.

[0065] like Figures 2 to 3 As shown, a filter plate 302 is slidably mounted inside the impurity collection tank 301. The filter plate 302 filters impurities from the adsorbed and purified liquid in the impurity collection tank 301 by moving.

[0066] like Figure 6As shown, a pair of cleaning handles 304 are fixedly mounted on the top of the filter plate 302. The filter plate 302 is moved by applying force to the pair of cleaning handles 304, thereby facilitating the filtration of impurities collected in the impurity collection tank 301.

[0067] like Figures 9 to 10 As shown, purification guide pipes 303 are evenly distributed on both sides of the impurity collection tank 301. The purification guide pipes 303 serve to connect the guide shroud 306 and the impurity collection tank 301, facilitating the delivery of air from the exhaust chamber into the impurity collection tank 301.

[0068] like Figures 9 to 10 As shown, a circulating cooling and dust suppression assembly is fixedly connected to one end of the purification guide pipe 303 located outside the cutting machine housing 1. The circulating cooling and dust suppression assembly includes a pair of dust filter cartridges 305, which are symmetrically arranged on both sides of the cutting machine housing 1. The pair of dust filter cartridges 305 provide filtration and flow guidance for the air delivered by the exhaust pipe 310.

[0069] like Figures 9 to 10 As shown, a guide shroud 306 is fixedly connected between each pair of dust filter cartridges 305 and the purification guide pipe 303. The guide shroud 306 serves to connect the dust filter cartridges 305 and the purification guide pipe 303. An exhaust fan 307 is fixedly installed inside the guide shroud 306. By controlling the operation of the exhaust fan 307, air inside the dust filter cartridges 305 is continuously discharged.

[0070] like Figures 9 to 10 As shown, a fixed base plate 308 is threadedly fitted to the bottom of the dust filter cartridge 305. The fixed base plate 308 serves to limit the assembly of the inner filter cartridge 309.

[0071] like Figures 9 to 10 As shown, an inner filter cylinder 309 is fixedly connected to one side of the fixed base plate 308 inside the dust filter cylinder 305. The air delivered by the air duct 310 is filtered through the inner filter cylinder 309.

[0072] Specifically, the inner filter cylinder 309 divides the dust filter cylinder 305 into a dust filter chamber and an exhaust chamber, and the guide shroud 306 is connected to the exhaust chamber.

[0073] like Figures 9 to 10 As shown, each pair of dust filter cartridges 305 is connected to the protective cover 103 by an exhaust pipe 310, which is connected to the dust filter chamber. The exhaust pipe 310 serves to connect the dust filter cartridges 305 and the purification guide pipe 303, facilitating the collection and diversion of exhaust gas and some chips generated during the cutting process of the cutting disc 104.

[0074] like Figures 6 to 8As shown, a pair of cleaning and positioning mechanisms 4 are fixedly assembled inside the cutting machine housing 1. The cleaning and positioning mechanisms 4 are used to perform auxiliary cleaning of multiple sets of supporting conveyor rollers 202 and to perform auxiliary support and positioning of metal plates.

[0075] like Figures 6 to 8 As shown, the cleaning positioning mechanism 4 includes a positioning bracket 401, which is slidably mounted inside the cutting machine housing 1. The positioning bracket 401 serves to limit the assembly of the cleaning brush 404 and the threaded connecting rod 405.

[0076] like Figures 6 to 8 As shown, a pair of cleaning cylinders 402 are fixedly installed inside the cutting machine housing 1. A piston rod 403 is slidably installed inside each of the cleaning cylinders 402, and the piston rod 403 is fixedly connected to the bottom surface of the positioning bracket 401. By controlling the extension and retraction of the piston rod 403, the positioning bracket 401 is lifted, thereby facilitating the adjustment of the contact state between the cleaning brush 404 and the supporting conveyor roller 202.

[0077] like Figures 6 to 8 As shown, multiple cleaning brushes 404 are fixedly mounted above the positioning bracket 401, and the multiple cleaning brushes 404 are arranged directly below multiple sets of supporting conveyor rollers 202. By moving the supporting conveyor rollers 202 and the cleaning brushes 404 relative to each other, impurities adhering to the surface of the supporting conveyor rollers 202 are cleaned, avoiding the adverse effects of impurities on the subsequent support and positioning process of the metal sheet.

[0078] like Figures 6 to 8 As shown, the positioning bracket 401 has several threaded connecting rods 405 threadedly connected to its upper part, and these threaded connecting rods 405 are arranged among multiple cleaning brushes 404. The threaded connecting rods 405 serve to support, fix, and adjust the position of the positioning block 406.

[0079] Preferably, the cleaning brush 404 and the threaded connecting rod 405 can be adaptively adjusted according to the actual size of the metal sheet and the cutting position.

[0080] like Figures 6 to 8 As shown, each of the threaded connecting rods 405 has a positioning block 406 fixedly mounted on its top end. The metal sheet is assisted in being supported and positioned by the movement of the positioning block 406.

[0081] Specifically, before use, the positioning bracket 401 can be lifted by extending the piston rod 403, thereby bringing multiple sets of cleaning brushes 404 into contact with the lower end face of the supporting conveyor roller 202, cleaning the surface of the supporting conveyor roller 202 through mutual contact. Simultaneously, several threaded connecting rods 405 can rise and fall synchronously with the positioning bracket 401, providing auxiliary support and positioning for the metal sheet. After cleaning, the cleaning positioning mechanism 4 is reset. Subsequently, the sheet to be cut can be placed on the multiple sets of supporting conveyor rollers 202, and the rotation of the multiple sets of supporting conveyor rollers 202 supports and rolls the sheet to be cut.

[0082] When the sheet metal to be cut moves below the cutting disc 104, the drive motor 216 drives the transmission pulley 215 to rotate. The threaded rod 212 rotates under the combined action of the drive pulley 213, the synchronous belt 214, and the transmission pulley 215. A pair of movable connecting frames 210 move in opposite directions with the rotation of the threaded rod 212 under the action of internal and external threads, thereby clamping the sheet metal to be cut by driving a pair of clamping and positioning plates 203 to move. The bottom surface of the sheet metal to be cut is supported by the supporting plate 204. At the same time, the clamping and positioning plates 203 are lifted by controlling the extension of a pair of cylinder piston rods 206, thereby supporting and clamping the sheet metal to be cut. Then, the cutting process of the sheet metal is realized by the rotation and movement of the cutting disc 104. The sheet metal falling during the cutting process can be supported and independently transported by multiple sets of supporting conveying rollers 202, realizing the purpose of step-by-step transportation of sheet metal and waste.

[0083] In addition, the adsorbed and purified liquid can be collected and stored in the impurity collection tank 301. During the cutting process of the cutting disc 104 on the metal sheet, the falling chips can be collected by the impurity collection tank 301, avoiding the adverse effects of chips on the subsequent conveying and positioning of the metal sheet and waste. Furthermore, the air in the exhaust chamber can be continuously drawn and transported by controlling the operation of the exhaust fan 307, so that the exhaust gas and some chips generated by the cutting disc 104 during the rotation cutting process can be transported to the impurity filter chamber along the air duct 310 under the action of airflow, and the impurities contained in the airflow are filtered by the inner filter screen 309.

[0084] The filtered exhaust gas can be transported to the exhaust pipe 310 along the purification guide pipe 303, and purified by the adsorption purification liquid. The purified gas can be transported from bottom to top along the impurity collection tank 301. The exhaust gas and chips generated during the cutting process of the cutting disc 104 can be further collected and treated by the continuous airflow.
