Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology and relates to a waste removal device, particularly a dust-collecting sorting and waste removal device for laser cutting of sheet metal. Background Technology

[0002] Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the material's boiling point in a very short time. The material then begins to vaporize, forming steam. This steam is ejected at a very high speed, creating cuts in the material as it is expelled.

[0003] Laser cutting can be divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture. In general, the cutting materials in these methods are fixed and the cutting head moves with multiple degrees of freedom. The waste generated by this method falls onto the supporting plate and cannot be quickly tilted and dropped out for sorting and waste removal. At the same time, existing cutting devices cannot stably collect dust and clean it regularly.

[0004] Therefore, we propose a dust-collecting sorting and waste removal device for laser cutting of sheet metal, which can stably suck up debris and dust and clean them regularly. It can tilt and pour out the waste, output it stably, and sort and collect it by category. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a dust-collecting sorting and waste removal device for laser cutting of sheet metal. The technical problem to be solved by this utility model is: how to achieve stable suction of debris and dust and regular cleaning, and how to tilt and pour out waste materials, provide stable output, and sort and collect them by category.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A dust-collecting sorting and waste removal device for laser cutting of sheet metal includes a sorting and waste removal mechanism, a discharge conveyor belt, and a dust collection box, a tilting discharge platform, and a positioning platform mechanism arranged sequentially from right to left. The tilting discharge platform has a waste removal component in the middle of its left side. The discharge conveyor belt is located below the positioning platform mechanism. The waste removal component is located between the discharge conveyor belt and the positioning platform mechanism. The positioning platform mechanism is equipped with a limit cylinder and a lifting positioning component, which are located behind the positioning platform mechanism. The sorting and waste removal mechanism is located in front of the discharge conveyor belt. Several waste collection boxes are located above the sorting and waste removal mechanism. The dust collection box is connected to an external exhaust fan.

[0008] The working principle of this utility model is as follows: Several waste collection boxes are placed above the sorting and waste discharge mechanism. The sorting and waste discharge mechanism can drive the waste collection boxes to move left and right. External handling equipment transports the material to be cut to the turning and discharging platform and positioning platform mechanism. Limit cylinders and lifting positioning components are used to block and position the material to be cut. After positioning, the limit cylinders and lifting positioning components retract below the positioning platform mechanism, releasing the positioning of the material to be cut. External laser cutting head device performs laser cutting on the material to be cut. During cutting, debris and dust are generated. The dust collection box is connected to an external exhaust fan, and the inside of the dust collection box forms... Negative pressure draws debris and dust into the dust collection box. After each cutting process, the waste falls onto the tipping discharge platform. Once the same type of waste falls onto the tipping discharge platform, the platform tilts, tilting the waste onto the waste discharge assembly. The waste then falls along the waste discharge assembly onto the discharge conveyor belt, which transports the same type of waste to one of the waste collection bins. When another type of waste is cut out, the sorting and discharge mechanism can move several waste collection bins left and right to switch to another waste collection bin. The waste is then output into that waste collection bin in the same way as above for sorting and discharge.

[0009] The dust collection box includes a filter box, a waste discharge cylinder is fixed at the lower end of the filter box, several supporting feet are provided below the waste discharge cylinder, a waste collection drawer is slidably provided inside the waste discharge cylinder, an air outlet connector is provided in the middle of the right side of the filter box, a filter screen is provided inside the air outlet connector, the air outlet connector is connected to an external exhaust fan, and a feed box is provided at the upper end of the filter box.

[0010] With the above structure, the air outlet is connected to an external exhaust fan, the filter screen is used for filtration and ventilation, and a negative pressure is formed inside the filter box. The debris and dust generated during cutting are sucked into the filter box through the feed box and then fall into the waste collection drawer. The waste collection drawer is pulled out periodically to clean the debris and dust inside.

[0011] The flipping discharge platform includes a vertical frame and a lifting frame. Several bases are fixed to the lower end of the vertical frame. Lifting slides are fixed to both the front and rear sides of the vertical frame. Several vertically lifting cylinders are fixed to the vertical frame. The lifting frame is fixed to the upper end of the telescopic ends of the lifting cylinders. Lifting sliders are fixed to both the front and rear ends of the inner side of the lifting frame. The lifting sliders are slidably disposed inside the lifting slides on the same side. Rotary seats are fixed to the upper ends of both the front and rear sides of the lifting frame. A rotating frame is provided between two rotating seats. Several flipping brush plates are fixed to the upper end of the flipping frame. A flipping cylinder is hinged between the front and rear sides of the flipping frame and the rear side of the lifting frame.

[0012] With the above structure, the telescopic ends of several lifting cylinders rise synchronously, lifting the lifting frame. At this time, the lifting slider slides inside the lifting slide on the same side to ensure the stable lifting of the lifting frame. The lifting frame drives the flipping frame and several flipping brush plates to rise and fall synchronously and stably. When the flipping frame descends to the waste discharge component, the flipping cylinder retracts, driving the flipping frame to rotate between the two rotating seats towards the waste discharge component, tilting and dumping the waste material that falls on the flipping brush plates onto the waste discharge component.

[0013] The waste discharge assembly includes two mounting frames, which are fixed to the front and rear ends of the left side of the upright frame, respectively. Inclined discharge hoppers are fixed on the two mounting frames.

[0014] With the above structure, the waste material slides onto the inclined discharge hopper and then slides steadily onto the discharge conveyor belt.

[0015] The positioning platform mechanism includes a positioning frame, with several platform brush plates fixed at the upper end of the positioning frame. Each platform brush plate is provided with several supporting balls. Two clearance holes are opened on the last platform brush plate. The lifting positioning component and the limiting cylinder are both set on the last platform brush plate. The height of the platform brush plate is consistent with the height of the flip brush plate when placed horizontally.

[0016] With the above structure, several support balls are used to support the plate, and at the same time, the plate can slide stably on the support balls. The lifting and positioning components and the limiting cylinder are both set on the platform brush plate on the last side, and can extend from the two clearance holes to position the plate to be cut, ensuring stable and accurate cutting.

[0017] The limiting cylinder is fixed to the lower end of the platform brush plate on the rearmost side, and the telescopic end of the limiting cylinder is located directly below one of the clearance holes; the lifting and positioning assembly includes a lifting cylinder, the telescopic end of which is fixed to the lower end of the platform brush plate on the rearmost side, a mounting plate is fixed on the lifting cylinder, a proximity sensor is fixed on the mounting plate, two bearing seats are fixed to the middle of the front side of the mounting plate, a rotatable swing rod is provided between the two bearing seats, a sliding limiting shaft and a touch control rod are provided on the swing rod, the end of the sliding limiting shaft is connected to the mounting plate, a top spring is sleeved on the sliding limiting shaft, the two ends of the top spring abut against the mounting plate and the swing rod respectively, the touch control rod is directly opposite the proximity sensor, and an ejector rod is fixed to the upper end of the swing rod; the ejector rod is located directly below another clearance hole and the ejector rod passes through the clearance hole.

[0018] With the above structure, the extension and retraction of the lifting cylinder's telescopic end drives the main body of the lifting cylinder to rise and fall in the opposite direction. The lifting cylinder drives the mounting plate to rise and fall, which in turn drives the proximity sensor, two bearing seats, sliding limit shaft, touch control rod, swing rod, and ejector rod to rise and fall synchronously. This causes the swing rod to rise and fall from the clearance hole, which in turn drives the ejector rod to rise and fall. The extension and retraction end of the limit cylinder extends from the corresponding clearance hole, and the ejector rod rises and extends from the corresponding clearance hole. After the plate abuts against the ejector rod, it pushes the swing rod to rotate on the two bearing seats, causing the swing rod to slide on the sliding limit shaft. The swing rod presses against the top spring, and the swing rod drives the touch control rod to move. The touch control rod abuts against the proximity sensor, controlling the equipment that places the external plate to stop pushing the plate, thus completing the plate positioning. After positioning, the lifting cylinder and limit cylinder descend and retract, and the top spring drives the swing rod to reset. At this time, the touch control rod disengages from the proximity sensor, ensuring that the equipment that places the external plate will stop pushing the plate the next time.

[0019] The discharge conveyor track machine includes a conveyor frame, with casters and lifting feet fixed on several legs at the lower end of the conveyor frame. A conveyor motor is fixed on the conveyor frame, and two track rollers are rotatably mounted on the conveyor frame. A conveyor track is provided between the two track rollers. The conveyor motor is fixed on the conveyor frame, and the output shaft of the conveyor motor is connected to one of the track rollers in a transmission connection.

[0020] With the above structure, the casters facilitate the movement of the discharge conveyor track machine. Once moved to the desired position, the lifting outriggers are adjusted to raise the casters off the ground. At this point, the position of the discharge conveyor track machine is fixed. The output shaft of the conveyor motor drives one of the track rollers to rotate. The two track rollers cooperate with the conveyor track to drive the conveyor track to perform the conveying work. The cut waste material falls onto the conveyor track and is then conveyed out.

[0021] The sorting and waste removal mechanism includes a box plate, a drag chain groove plate, a chain groove plate, two guide rail frames, and two adjusting rod seats. Two symmetrically arranged limiters are fixed to the upper left and right sides of each guide rail frame. The drag chain groove plate, chain groove plate, and two adjusting rod seats are located between the two guide rail frames, with the two adjusting rod seats positioned on the front and rear sides of the two guide rail frames. A guide chain is provided between the two adjusting rod seats, located inside the chain groove plate. Four symmetrically arranged support guide wheels are fixed to the lower end of the box plate, engaging and abutting against the upper end of the guide rail frame on the same side. A mounting plate is fixed to the middle of the lower end of the box plate, and an adjusting motor is fixed to the mounting plate. The motor rotates on the mounting plate... The device is equipped with a drive sprocket and two support sprockets, located on the left and right sides of the drive sprocket. The output shaft of the adjustment motor is connected to the rotating shaft of the drive sprocket. Both the drive sprocket and the two support sprockets are driven by a guide chain. A cable-carrying cable chain is provided between the box-holding plate and the cable tray. A storage plate is fixed to the left side of the two left-side support guide wheels. A support wheel is fixed to the lower end of the storage plate. The support wheel rolls against the upper end of the guide rail frame at the corresponding position. Each guide rail frame is equipped with two directional arrows. A photoelectric sensor is fixed to the left side of each support guide wheel. Several sets of symmetrically arranged positioning plates are fixed to the upper end of the box-holding plate. The four positioning plates form a box-holding area.

[0022] Using the above structure, adjusting the adjusting rods on the two adjusting rod seats tightens the guide chain, ensuring stable transmission between the drive sprocket and the two support sprockets. The output shaft of the adjusting motor drives the drive sprocket's shaft to rotate, causing the drive sprocket to move left and right along the guide chain. This, in turn, drives the mounting plate to move left and right. The mounting plate then moves the box-holding plate, which in turn moves the four symmetrically arranged support guide wheels along the upper end of the guide rail frame on the same side. Simultaneously, the two left-side support guide wheels move the storage plate left and right in sync. A cable-carrying cable chain is provided between the storage plate and the drag chain trough for cable routing, powering the photoelectric sensor and the adjusting motor. When moving to the far left and far right, the right-side support guide wheel and the left-side storage plate will abut against the limit switch on the same side to limit their movement and prevent them from falling. The box-holding area is used to place several waste collection boxes. The photoelectric sensor monitors the position of the box-holding plate, ensuring that the waste collection boxes are directly facing the discharge conveyor belt to collect different types of waste. Material boxes can be added to the storage plate as needed for waste collection.

[0023] The waste collection bin is locked inside the corresponding placement area, and several lifting rings are provided on both the upper left and right sides of the waste collection bin.

[0024] Using the above structure, several lifting rings are used to lift and place the waste collection bins, and to lock the waste collection bins into place in the corresponding bin placement area.

[0025] Compared with existing technologies, this dust-collecting sorting and waste removal device for laser cutting of sheet metal has the following advantages:

[0026] By connecting the dust collection box to an external exhaust fan, debris and smoke are sucked into the dust collection box, and the debris and smoke inside are cleaned regularly.

[0027] The tilting discharge platform works in conjunction with the positioning platform mechanism to stably support and transport the sheet material to be cut. The tilting discharge platform is used to tilt the waste material onto the waste discharge component, and the waste material falls along the waste discharge component onto the discharge conveyor belt.

[0028] By cooperating with the waste discharge component and the discharge conveyor belt, stable conveying and discharge of waste materials can be achieved;

[0029] The positioning platform mechanism, in conjunction with the limit cylinder and the lifting positioning component, is used to stably and quickly position the material to be cut, ensuring accurate cutting.

[0030] By cooperating with several waste collection bins, the discharge conveyor belt can move the waste collection bins left and right, switch the position of the waste collection bins, and collect the discharged waste materials according to their categories. Attached Figure Description

[0040] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0041] like Figures 1-8 As shown, this dust-collecting sorting and waste removal device for laser cutting of sheet metal includes a sorting and waste removal mechanism 1, a discharge conveyor belt 2, and a dust collection box 5, a tilting discharge platform 4, and a positioning platform mechanism 3 arranged sequentially from right to left. A waste removal component is provided in the middle left side of the tilting discharge platform 4. The discharge conveyor belt 2 is located below the positioning platform mechanism 3. The waste removal component is located between the discharge conveyor belt 2 and the positioning platform mechanism 3. The positioning platform mechanism 3 is equipped with a limit cylinder 31 and a lifting positioning component 30. The limit cylinder 31 and the lifting positioning component 30 are located on the rear side of the positioning platform mechanism 3. The sorting and waste removal mechanism 1 is located in front of the discharge conveyor belt 2. Several waste collection boxes 6 are provided above the sorting and waste removal mechanism 1. The dust collection box 5 is connected to an external exhaust fan.

[0042] Several waste collection boxes 6 are placed above the sorting and waste discharge mechanism 1. The sorting and waste discharge mechanism 1 can move the waste collection boxes 6 left and right. External handling equipment transports the material to be cut to the turning and discharging platform 4 and the positioning platform mechanism 3. The limit cylinder 31 and the lifting and positioning component 30 are used to block and position the material to be cut. After positioning, the limit cylinder 31 and the lifting and positioning component 30 are retracted to the bottom of the positioning platform mechanism 3, releasing the positioning of the material to be cut. The external laser cutter head device performs laser cutting on the material to be cut. During cutting, debris and dust will be generated. The dust collection box 5 is connected to an external exhaust fan, and a negative pressure is formed inside the dust collection box 5. The debris and dust are sucked into the dust collection box 5. After each cutting process is completed, the cut waste falls onto the turning and discharging platform 4. After the same type of waste falls onto the turning and discharging platform 4, the turning and discharging platform 4 will tilt and pour the waste onto the waste discharge component. The waste falls along the waste discharge component onto the discharge conveyor belt 2. The discharge conveyor belt 2 transports the same type of waste to one of the waste collection boxes 6. When another type of waste is cut out, the sorting and discharging mechanism 1 can drive several waste collection boxes 6 to move left and right, switch to another waste collection box 6, and output to the waste collection box 6 in the same way as above for sorting and discharging waste by type.

[0043] The dust collection box 5 includes a filter box 10. A waste discharge cylinder 8 is fixed at the lower end of the filter box 10. Several supporting feet 7 are provided below the waste discharge cylinder 8. A waste collection drawer 9 is slidably provided inside the waste discharge cylinder 8. An air outlet 12 is provided in the middle of the right side of the filter box 10 and is connected to it. A filter screen 13 is provided inside the air outlet 12. The air outlet 12 is connected to an external exhaust fan. A feed box 11 is provided at the upper end of the filter box 10.

[0044] The air outlet connector 12 is connected to an external exhaust fan. The filter screen 13 is used for filtration and ventilation. A negative pressure is formed inside the filter box 10, which draws the debris and dust generated during cutting into the filter box 10 through the feed box 11 and then into the waste collection drawer 9. The waste collection drawer 9 is pulled out periodically to clean the debris and dust inside.

[0045] The flipping discharge platform 4 includes a vertical frame 15 and a lifting frame 18. Several bases 14 are fixed to the lower end of the vertical frame 15. Lifting slides 16 are fixed to both the front and rear sides of the vertical frame 15. Several vertically lifting cylinders 17 are fixed on the vertical frame 15. The lifting frame 18 is fixed to the upper end of the telescopic ends of the lifting cylinders 17. Lifting sliders 19 are fixed to both the front and rear ends of the inner side of the lifting frame 18. The lifting sliders 19 are slidably disposed inside the lifting slides 16 on the same side. Rotary seats 22 are fixed to the upper ends of both the front and rear sides of the lifting frame 18. A rotating flipping frame 20 is provided between the two rotating seats 22. Several flipping brush plates 21 are fixed to the upper end of the flipping frame 20. A flipping cylinder 23 is hinged between the front and rear sides of the flipping frame 20 and the rear side of the lifting frame 18.

[0046] The telescopic ends of several lifting cylinders 17 rise synchronously, lifting the lifting frame 18. At this time, the lifting slider 19 slides inside the lifting slide seat 16 on the same side to ensure the stable lifting of the lifting frame 18. The lifting frame 18 drives the flipping frame 20 and several flipping brush plates 21 to rise and fall synchronously and stably. When the flipping frame 20 descends to the waste discharge component, the flipping cylinder 23 retracts, driving the flipping frame 20 to rotate between the two rotating seats 22 towards the waste discharge component, tilting and dumping the waste material that falls on the flipping brush plates 21 onto the waste discharge component.

[0047] The waste discharge assembly includes two mounting brackets 25, which are fixed to the front and rear ends of the left side of the upright frame 15, respectively. Inclined discharge hoppers 24 are fixed on the two mounting brackets 25.

[0048] The waste material slides onto the inclined discharge hopper 24 and then slides steadily onto the discharge conveyor belt 2.

[0049] The positioning platform mechanism 3 includes a positioning frame 26. Several platform brush plates 27 are fixed at the upper end of the positioning frame 26. Several support balls 28 are provided on each platform brush plate 27. Two clearance holes 29 are opened on the last platform brush plate 27. The lifting positioning component 30 and the limiting cylinder 31 are both set on the last platform brush plate 27. The height of the platform brush plate 27 is the same as the height of the flip brush plate 21 when it is placed horizontally.

[0050] Several support balls 28 are used to support the plate and facilitate the plate to slide stably on the support balls 28. The lifting and positioning component 30 and the limiting cylinder 31 are both set on the platform brush plate 27 on the last side and can extend from the two clearance holes 29 to position the plate to be cut and ensure stable and accurate cutting.

[0051] A limiting cylinder 31 is fixed to the lower end of the platform brush plate 27 on the rearmost side, and the telescopic end of the limiting cylinder 31 is located directly below one of the clearance holes 29; the lifting and positioning assembly 30 includes a lifting cylinder 32, the telescopic end of the lifting cylinder 32 is fixed to the lower end of the platform brush plate 27 on the rearmost side, a mounting plate 34 is fixed on the lifting cylinder 32, a proximity sensor 33 is fixed on the mounting plate 34, and two bearing seats 38 are fixed to the middle of the front side of the mounting plate 34, with a space between the two bearing seats 38. There is a rotatable positioning rod 36, on which a sliding limit shaft 37 and a touch control rod 35 are provided. The end of the sliding limit shaft 37 is connected to the mounting plate 34. A top spring is sleeved on the sliding limit shaft 37. The two ends of the top spring abut against the mounting plate 34 and the positioning rod 36 respectively. The touch control rod 35 is directly opposite the proximity sensor 33. An ejector rod is fixed at the upper end of the positioning rod 36. The ejector rod is located directly below another clearance hole 29 and passes through the clearance hole 29.

[0052] The telescopic end of the lifting cylinder 32 extends and retracts, thereby driving the main body of the lifting cylinder 32 to rise and fall in the opposite direction. The lifting cylinder 32 drives the mounting plate 34 to rise and fall, which in turn drives the proximity sensor 33, the two bearing seats 38, the sliding limit shaft 37, the touch control rod 35, the swing rod 36, and the ejector rod to rise and fall synchronously. This causes the swing rod 36 to rise and fall from the clearance hole, which in turn drives the ejector rod to rise and fall. The telescopic end of the limit cylinder 31 extends from the clearance hole at the corresponding position, and the ejector rod rises and extends from the clearance hole at the corresponding position. After the plate abuts against the ejector rod, it pushes the swing rod 36. Rotating on the two bearing seats 38 causes the positioning rod 36 to slide on the sliding limit shaft 37. The positioning rod 36 presses against the top spring, and the positioning rod 36 drives the touch control rod 35 to move. The touch control rod 35 abuts against the proximity sensor 33, controlling the device for placing the external board to stop pushing the board, thus completing the board positioning. After positioning, the lifting cylinder 32 and the limit cylinder 31 descend and retract, and the top spring drives the positioning rod 36 to reset. At this time, the touch control rod 35 disengages from the proximity sensor 33, ensuring that the device for placing the external board will stop pushing the board next time.

[0053] The discharge conveyor track machine 2 includes a conveyor support 41. Several legs at the lower end of the conveyor support 41 are fixed with casters 39 and lifting feet 40. A conveyor motor 43 is fixed on the conveyor support 41. Two track rollers are rotatably mounted on the conveyor support 41. A conveyor track 42 is provided between the two track rollers. The conveyor motor 43 is fixed on the conveyor support 41. The output shaft of the conveyor motor 43 is connected to one of the track rollers.

[0054] The casters 39 facilitate the movement of the discharge conveyor track 2. Once moved to the desired position, the lifting support legs 40 are adjusted to raise the casters 39 off the ground. At this point, the position of the discharge conveyor track 2 is fixed. The output shaft of the conveyor motor 43 drives one of the track rollers to rotate. The two track rollers cooperate with the conveyor track 42 to drive the conveyor track 42 to perform conveying work. The cut waste falls onto the conveyor track 42 and is then conveyed out.

[0055] The sorting and waste removal mechanism 1 includes a box plate 51, a drag chain groove plate 48, a chain groove plate 58, two guide rail frames 44, and two adjusting rod seats 46. Two symmetrically arranged limiters 45 are fixed to the upper left and right sides of each guide rail frame 44. The drag chain groove plate 48, the chain groove plate 58, and the two adjusting rod seats 46 are located between the two guide rail frames 44, with the two adjusting rod seats 46 located on the front and rear sides of the two guide rail frames 44. A guide chain 47 is provided between the two adjusting rod seats 46, and the guide chain 47 is located inside the chain groove plate 58. Four symmetrically arranged support guide wheels 52 are fixed to the lower end of the box plate 51. The support guide wheels 52 engage and abut against the upper end of the guide rail frame 44 on the same side. A mounting plate 54 is fixed to the middle of the lower end of the box plate 51, and an adjusting motor 60 is fixed on the mounting plate 54. The upper part is equipped with a drive sprocket 56 and two support sprockets 57. The two support sprockets 57 are located on the left and right sides of the drive sprocket 56. The output shaft of the adjustment motor 60 is connected to the rotating shaft of the drive sprocket 56. The drive sprocket 56 and the two support sprockets 57 are both driven by the guide chain 47. A cable-carrying cable chain 49 is provided between the box plate 51 and the cable tray plate 48. A storage plate 50 is fixed to the left side of the two left support guide wheels 52. A support wheel is fixed to the lower end of the storage plate 50. The support wheel rolls against the upper end of the guide rail frame 44 at the corresponding position. Two directional arrows 55 are provided on each guide rail frame 44. A photoelectric sensor 59 is fixed to the left side of each support guide wheel 52. Several sets of symmetrically arranged positioning plates 53 are fixed to the upper end of the box plate 51. The four positioning plates 53 form a box-holding area.

[0056] Adjusting the adjusting rods on the two adjusting rod seats 46 tightens the guide chain 47, ensuring that the drive sprocket 56 and the two support sprockets 57 are stably engaged with the guide chain 47. The output shaft of the adjusting motor 60 drives the shaft of the drive sprocket 56 to rotate, causing the drive sprocket 56 to move left and right along the guide chain 47. This, in turn, causes the mounting plate 54 to move left and right. The mounting plate 54 then moves the box plate 51, which in turn moves the four symmetrically arranged support guide wheels 52 along the upper end of the guide rail frame 44 on the same side. Simultaneously, the two left-side support guide wheels 52 move the storage plate 50 synchronously. The device moves left and right. A cable-carrying chain 49 is provided between the box plate 51 and the cable tray plate 48 for cable routing, which powers the photoelectric sensor 59 and the adjustment motor 60. When it moves to the leftmost and rightmost positions, the support guide wheel 52 on the right side and the storage plate 50 on the left side will abut against the limiter 45 on the same side to limit the movement and prevent it from falling. The box area is used to place several waste collection boxes 6. The photoelectric sensor 59 is used to monitor the position of the box plate 51 so that the waste collection boxes 6 are respectively facing the discharge conveyor belt 2 for collecting different waste materials. Material boxes can be added to the storage plate 50 as needed for waste collection.

[0057] The waste collection box 6 is locked inside the corresponding placement area, and several lifting rings are provided on the upper left and right sides of the waste collection box 6.

[0058] Several lifting rings are used to lift and place the waste collection box 6, and to lock the waste collection box 6 into the corresponding placement area.

[0059] The working principle of this utility model is as follows: the caster 39 facilitates the movement of the material conveying crawler 2. When it moves to the required position, the lifting support 40 is adjusted, and the lifting support 40 is raised to lift the caster 39 off the ground. At this time, the position of the material conveying crawler 2 is fixed.

[0060] Adjust the adjusting rods on the two adjusting rod seats 46 to tighten the guide chain 47 so that the drive sprocket 56 and the two support sprockets 57 are in transmission engagement with the guide chain 47;

[0061] The empty waste collection box 6 is lifted and placed into the corresponding placement area by the lifting ring. The sorting and waste discharge mechanism 1 can drive several waste collection boxes 6 to move left and right.

[0062] External handling equipment transports the sheet metal to be cut to the flipping and unloading platform 4 and the positioning platform mechanism 3. Limit cylinder 31 and lifting and positioning assembly 30 are used to block and position the sheet metal to be cut. Specifically, the extension and retraction of the extension end of the lifting cylinder 32 causes the main body of the lifting cylinder 32 to rise and fall in the opposite direction. The lifting cylinder 32 then drives the mounting plate 34 to rise and fall, which in turn drives the proximity sensor 33, two bearing seats 38, sliding limit shaft 37, touch control rod 35, swing rod 36, and ejector rod to rise and fall synchronously. This causes the swing rod 36 to rise and fall from the clearance hole, which in turn drives the ejector rod to rise and fall. The extension and retraction end of the limit cylinder 31 extends from the clearance hole at the corresponding position, and the ejector rod rises from the corresponding position. The clearance hole extends, and after the plate abuts against the ejector rod, it pushes the positioning rod 36 to rotate on the two bearing seats 38, causing the positioning rod 36 to slide on the sliding limit shaft 37. The positioning rod 36 presses against the top spring, and the positioning rod 36 drives the touch control rod 35 to move. The touch control rod 35 abuts against the proximity sensor 33, controlling the external plate placement equipment to stop pushing the plate, completing the plate positioning. After positioning, the lifting cylinder 32 and the limit cylinder 31 descend and retract, and the top spring drives the positioning rod 36 to reset. At this time, the touch control rod 35 disengages from the proximity sensor 33, ensuring that the next time the external plate placement equipment is controlled, it stops pushing the plate, releasing the positioning of the plate to be cut.

[0063] The external laser cutter head device performs laser cutting on the material to be cut. During the cutting process, debris and dust are generated. The dust collection box 5 is connected to an external exhaust fan. A negative pressure is formed inside the dust collection box 5 to suck the debris and dust into the dust collection box 5. The exhaust connector 12 is connected to the external exhaust fan. The filter screen 13 is used for filtration and ventilation. A negative pressure is formed inside the filter box 10 to suck the debris and dust generated during cutting into the filter box 10 through the feed box 11, and then into the waste collection drawer 9. The waste collection drawer 9 is pulled out periodically to clean the debris and dust inside the waste collection drawer 9.

[0064] After each cutting process is completed, the waste material falls onto the flipping discharge platform 4. When the same type of waste material falls onto the flipping discharge platform 4, the platform tilts, causing the telescopic ends of several lifting cylinders 17 to rise synchronously, lifting the lifting frame 18. At this time, the lifting slider 19 slides inside the lifting slide block 16 on the same side, ensuring the stable lifting of the lifting frame 18. The lifting frame 18 drives the flipping frame 20 and several flipping brush plates 21 to rise and fall synchronously and stably. When the flipping frame 20 descends to the waste discharge component, the flipping cylinder 23 retracts, driving the flipping frame 20 to fall back down. Rotating between the two rotating seats 22 towards the waste discharge assembly, the waste material falling on the flipping brush plate 21 is tilted and poured out, sliding onto the waste discharge assembly, that is, the waste material slides onto the inclined discharge hopper 24, and stably slides onto the conveyor belt 42 of the discharge conveyor 2. The output shaft of the conveyor motor 43 drives one of the conveyor rollers to rotate. The two conveyor rollers cooperate with the conveyor belt 42 to drive the conveyor belt 42 to perform the conveying work. After the cut waste material falls onto the conveyor belt 42, it is conveyed out and transported into one of the waste collection boxes 6.

[0065] When another type of waste material is cut out, the output shaft of the adjusting motor 60 drives the shaft of the drive sprocket 56 to rotate, causing the drive sprocket 56 to move left and right along the guide chain 47. This, in turn, causes the mounting plate 54 to move left and right. The mounting plate 54 then moves the box plate 51, which in turn moves the four symmetrically arranged support guide wheels 52 along the upper end of the guide rail frame 44 on the same side. At the same time, the two support guide wheels 52 on the left side move the storage plate 50 left and right synchronously. The storage plate 51 and the drag chain trough plate 48 are now aligned. A cable drag chain 49 is provided for cable routing, powering the photoelectric sensor 59 and the adjustment motor 60. When it moves to the leftmost and rightmost positions, the support guide wheel 52 on the right and the storage plate 50 on the left will abut against the limiter 45 on the same side to limit the movement and prevent it from falling. The box area is used to place several waste collection boxes 6. The photoelectric sensor 59 is used to monitor the position of the box plate 51. Switching makes another waste collection box 6 face the discharge conveyor 2 to collect different waste materials and sort and discharge them by type.

[0066] Once the waste collection bin 6 is full, it is lifted away by several lifting rings, and then a new empty waste collection bin 6 is used to continue sorting and discharging waste according to its type.

[0067] In summary, by connecting the dust collection box 5 to an external exhaust fan, debris and smoke are sucked into the dust collection box 5, and the debris and smoke inside are cleaned regularly.

[0068] The flipping discharge platform 4 works in conjunction with the positioning platform mechanism 3 to stably support and transport the sheet material to be cut. The flipping discharge platform 4 is tilted to tilt the waste material onto the waste discharge component. The waste material falls along the waste discharge component onto the discharge conveyor track 2.

[0069] By cooperating with the waste discharge component and the discharge conveyor track 2, stable conveying and discharge of waste materials can be achieved;

[0070] The positioning platform mechanism 3 works in conjunction with the limit cylinder 31 and the lifting positioning component 30 to stably and quickly position the plate to be cut, ensuring accurate cutting.

[0071] By cooperating with several waste collection boxes 6, the discharge conveyor 2 can move several waste collection boxes 6 left and right, switch the position of the waste collection boxes 6, and collect the discharged waste materials according to their categories.

[0072] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
