Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting, and relates to a waste discharging device, in particular to a dust-absorbing sorting waste discharging device for laser cutting of plates. Background Art

[0002] Laser cutting uses a laser beam with a high energy density to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short time. The material begins to vaporize and form vapor. The ejection speed of these vapors is very high, and while the vapors are ejected, a cut is formed on the material.

[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 the above cutting methods, generally the plate is fixed and the cutting head performs multi-degree-of-freedom displacement. The waste generated by this cutting method will fall onto the supporting vertical plate and cannot quickly tilt out for sorting and discharging of waste. At the same time, the existing cutting device cannot stably absorb dust and clean it regularly.

[0004] Therefore, we propose a dust-absorbing sorting waste discharging device for laser cutting of plates, which can stably suck in debris and smoke and clean it regularly, and can tilt out waste, stably output it, and sort and collect it by category. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and propose a dust-absorbing sorting waste discharging device for laser cutting of plates. The technical problem to be solved by this invention is: how to stably suck in debris and smoke and clean it regularly, and can tilt out waste, stably output it, and sort and collect it by category.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A dust-absorbing sorting waste discharging device for laser cutting of plates includes a sorting and waste discharging mechanism, a discharging conveyor track machine, and a dust-absorbing box, a flipping discharging platform, and a positioning platform mechanism arranged in sequence from right to left. A waste discharging component is provided in the middle of the left side of the flipping discharging platform. The discharging conveyor track machine is located below the positioning platform mechanism. The waste discharging component is located between the discharging conveyor track machine and the positioning platform mechanism. A limiting air cylinder and a lifting and positioning component are provided on the positioning platform mechanism. The limiting air cylinder and the lifting and positioning component are located at the rear side of the positioning platform mechanism. The sorting and waste discharging mechanism is located in front of the discharging conveyor track machine. A plurality of waste collection boxes are provided above the sorting and waste discharging mechanism. The dust-absorbing box is connected to an external exhaust fan.

[0007] Working principle of the present invention: A number of waste collection bins are placed above the sorting and waste discharging mechanism. The sorting and waste discharging mechanism can drive the waste collection bins to move left and right. An external handling device transports the plate to be cut to the turning and discharging platform and the positioning platform mechanism. The limiting cylinder and the lifting and positioning assembly are used to block and position the plate to be cut. After positioning, the limiting cylinder and the lifting and positioning assembly retract below the positioning platform mechanism to release the positioning of the plate to be cut. An external laser cutter device cuts the plate to be cut by laser. During cutting, debris and dust are generated. The dust collection box is connected to an external exhaust fan, and a negative pressure is formed inside the dust collection box to suck the debris and dust into the interior of the dust collection box. After each cutting process is completed, the cut waste will fall onto the turning and discharging platform. After the same type of waste falls onto the turning and discharging platform, the turning and discharging platform will tilt to pour the waste into the waste discharging assembly obliquely. The waste will fall along the waste discharging assembly onto the discharging conveyor belt, and the discharging conveyor belt transports the same type of waste into one of the waste collection bins. When another type of waste is cut, the sorting and waste discharging mechanism can drive the waste collection bins to move left and right to switch to another waste collection bin, and output it into the waste collection bin in the same way as above to sort and discharge the waste by category.

[0008] The dust collection box includes a filter box. A waste discharging cylinder is fixed at the lower end of the filter box. A number of support feet are provided below the waste discharging cylinder. A waste collection drawer is slidably arranged inside the waste discharging cylinder. An air outlet joint is provided in the middle of the right side of the filter box and is communicated with the filter box. A filter screen is arranged inside the air outlet joint. The air outlet joint is connected to an external exhaust fan. A feeding box is arranged at the upper end of the filter box.

[0009] With the above structure, the air outlet joint is connected to an external exhaust fan. The filter screen is used for filtering ventilation. A negative pressure is formed inside the filter box to suck the debris and dust generated during cutting into the filter box through the feeding box and then fall into the waste collection drawer. The waste collection drawer is pulled out regularly to clean the debris and dust inside the waste collection drawer.

[0010] The turning and discharging platform includes a vertical frame and a lifting frame. A number of bases are fixed at the lower end of the vertical frame. Lifting slide seats are fixed on both the front and rear sides of the vertical frame. A number of vertically lifting cylinders are fixed on the vertical frame. The lifting frame is fixed at the upper ends of the telescopic ends of the lifting cylinders. Lifting sliders are fixed at both the front and rear inner ends of the lifting frame. The lifting sliders are slidably arranged inside the lifting slide seats on the same side. Rotating seats are fixed at the upper ends of both the front and rear sides of the lifting frame. A turning frame is rotatably arranged between the two rotating seats. A number of turning brush plates are fixed at the upper end of the turning frame. Turning cylinders are hinged between the front and rear sides of the turning frame and the rear side of the lifting frame.

[0011] With the above structure, the telescopic ends of several lifting cylinders rise synchronously to lift the lifting frame. At this time, the lifting sliders slide inside the lifting slide seats 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 lift synchronously and stably. When the flipping frame descends to the waste discharging assembly, the flipping cylinder retracts, driving the flipping frame to rotate between the two rotating seats towards the waste discharging assembly, and tilting and pouring out the waste on the flipping brush plates, which slides onto the waste discharging assembly.

[0012] The waste discharging assembly includes two mounting frames, which are respectively fixed at the front and rear ends on the left side of the vertical frame, and an inclined discharge chute hopper is fixed on the two mounting frames.

[0013] With the above structure, the waste slides onto the inclined discharge chute hopper and stably slides onto the discharge conveyor track.

[0014] The positioning platform mechanism includes a positioning frame. Several platform brush plates are fixed at the upper end of the positioning frame. A number of support balls are provided on the platform brush plates. Two avoidance holes are opened on the last platform brush plate. The lifting positioning assembly and the limit cylinder are both arranged on the last platform brush plate. The height of the platform brush plate is the same as that of the flipping brush plate when placed horizontally.

[0015] With the above structure, a number of support balls are used to support the plate, and at the same time, it is convenient for the plate to slide stably on the support balls. The lifting positioning assembly and the limit cylinder are both arranged on the last platform brush plate and can extend out from the two avoidance holes to position the plate to be cut, ensuring stable and accurate cutting.

[0016] The limit cylinder is fixed at the lower end of the last platform brush plate, and the telescopic end of the limit cylinder is located directly below one of the avoidance holes; the lifting positioning assembly includes a lifting cylinder. The telescopic end of the lifting cylinder is fixed at the lower end of the last platform brush plate. An installation vertical plate is fixed on the lifting cylinder. A proximity sensor is fixed on the installation vertical plate. Two bearing seats are fixed in the middle of the front side of the installation vertical plate. A rotatable swing rod is arranged between the two bearing seats. A sliding limit shaft and a touch control rod are arranged through the swing rod. The end of the sliding limit shaft is connected through the installation vertical plate. A top position spring is sleeved on the sliding limit shaft, and both ends of the top position spring abut between the installation vertical plate and the swing rod. The touch control rod is directly opposite to the proximity sensor, and a top rod is fixed at the upper end of the swing rod; the top rod is located directly below the other avoidance hole and the top rod penetrates through the avoidance hole.

[0017] With the above structure, the telescopic end of the lifting cylinder expands and contracts, thereby driving the main body of the lifting cylinder to move up and down in the reverse direction. The lifting cylinder drives the installation vertical plate to move up and down, that is, drives the proximity sensor, two bearing seats, sliding limit shafts, touch control rods, swing rods and ejector rods to move up and down synchronously, so that the swing rod rises and falls from the avoidance hole, and then drives the ejector rod to rise and fall. The telescopic end of the limit cylinder extends from the avoidance hole at the corresponding position, and the ejector rod rises and extends from the avoidance hole at the corresponding position. After the sheet material abuts against the ejector rod, it pushes the swing rod to rotate on the two bearing seats, so that the swing rod slides on the sliding limit shaft, the swing rod presses the top position spring, the swing rod drives the touch control rod to move, the touch control rod abuts against the proximity sensor, and controls the equipment for placing the sheet material externally to stop pushing the sheet material, completing the positioning of the sheet material. After the positioning is completed, the lifting cylinder and the limit cylinder descend and retract, and the top position spring drives the swing rod to reset. At this time, the touch control rod disengages from the proximity sensor, ensuring that the equipment for placing the sheet material externally is controlled to stop pushing the sheet material next time.

[0018] The discharging conveyor track machine includes a conveying support. Casters and lifting feet are fixed on several leg rods at the lower end of the conveying support. A conveying motor is fixed on the conveying support. Two track rollers are rotatably arranged on the conveying support. A conveying track is arranged between the two track rollers. A conveying motor is fixed on the conveying support, and the output shaft of the conveying motor is in transmission connection with one of the track rollers.

[0019] With the above structure, the casters facilitate the movement of the discharging conveyor track machine. Move it to the required position and adjust the lifting feet. The lifting feet rise to lift the casters off the ground. At this time, the position of the discharging conveyor track machine is fixed. The output shaft of the conveying motor drives one of the track rollers to rotate. The two track rollers cooperate with the conveying track to drive the conveying track to perform the conveying work. After the cut waste falls on the conveying track, it is conveyed out.

[0020] The sorting and waste discharging mechanism includes a box placing plate, a drag chain groove plate, a chain groove plate, two guide rail frames and two position adjusting rod seats. On the upper end of each guide rail frame, two symmetrically arranged limiters are fixed on both the left and right sides. The drag chain groove plate, the chain groove plate and the two position adjusting rod seats are located between the two guide rail frames, and the two position adjusting rod seats are located on the front and rear sides of the two guide rail frames. A guiding chain is arranged between the two position adjusting rod seats and is located inside the chain groove plate. Four support guide wheels are fixed at the lower end of the box placing plate, and the support guide wheels are engaged and abutted against the upper end of the guide rail frame on the same side. In the middle of the lower end of the box placing plate, a mounting plate is fixed, and a position adjusting motor is fixed on the mounting plate. A driving sprocket and two support sprockets are rotatably arranged on the mounting plate. The two support sprockets are located on the left and right sides of the driving sprocket. The output shaft of the position adjusting motor is in transmission connection with the rotating shaft of the driving sprocket. The driving sprocket and the two support sprockets are all in transmission cooperation with the guiding chain. A wire dragging chain is arranged between the box placing plate and the drag chain groove plate for wire routing to supply power to the photoelectric sensors and the position adjusting motor. On the left side of the two left support guide wheels, a placing plate is fixed, and a support wheel is fixed at the lower end of the placing plate. The support wheel is in rolling contact with the upper end of the guide rail frame at the corresponding position. Two pointing arrows are arranged on each guide rail frame, and photoelectric sensors are fixed on the left side of each support guide wheel. A number of groups of symmetrically arranged clamping vertical plates are fixed on the upper end of the box placing plate, and a box placing area is formed between the four clamping vertical plates.

[0021] With the above structure, adjust the position adjusting rods on the two position adjusting rod seats to tighten the guiding chain, so that the driving sprocket and the two support sprockets are all in stable transmission cooperation with the guiding chain. The output shaft of the position adjusting motor drives the rotating shaft of the driving sprocket to rotate, driving the driving sprocket to move left and right along the guiding chain, thereby driving the mounting plate to move left and right in reverse. The mounting plate drives the box placing plate to move, and then drives the four support guide wheels arranged symmetrically in pairs front and back to move along the upper end of the guide rail frame on the same side. At the same time, the two left support guide wheels drive the placing plate to move left and right synchronously. A wire dragging chain is arranged between the box placing plate and the drag chain groove plate for wire routing to supply power to the photoelectric sensors and the position adjusting motor. When moving to the leftmost and rightmost positions, the right support guide wheel and the left placing plate on the left side will abut against the limiters on the same side for limiting to prevent falling. The box placing area is used to place a number of waste collecting boxes. The photoelectric sensors are used to monitor the moving position of the box placing plate, so that the waste collecting boxes are respectively aligned with the discharge conveying crawler conveyor for collecting different wastes. The placing plate can be added with material boxes as needed for collecting wastes.

[0022] The waste collecting box is clamped inside the box placing area at the corresponding position, and a number of lifting rings are arranged on both the left and right sides of the upper end of the waste collecting box.

A negative pressure is formed inside the dust suction box 5 to suck the debris and dust into the interior of the dust suction box 5. After each cutting process is completed, the cut waste will fall onto the turning discharging platform 4. After the same kind of waste falls onto the turning discharging platform 4, the turning discharging platform 4 will tilt to pour the waste into the waste discharging assembly obliquely. The waste falls along the waste discharging assembly onto the discharging conveyor track 2. The discharging conveyor track 2 conveys the same kind of waste into one of the waste collection bins 6. When another kind of waste is cut, the sorting and waste discharging mechanism 1 can drive the several waste collection bins 6 to move left and right, switch to another waste collection bin 6, and output it into the interior of this waste collection bin 6 in the same way as above for sorting and discharging waste by category.

The telescopic end of the limit cylinder 30 extends out from the avoidance hole at the corresponding position, and the ejector rod rises and extends out from the avoidance hole at the corresponding position. After the sheet material abuts against the ejector rod, it pushes the positioning rod 36 to rotate on the two bearing seats 38, so that the positioning rod 36 slides on the sliding limit shaft 37. The positioning rod 36 presses the top position spring, and the positioning rod 36 drives the touch control rod 35 to move.

The output shaft of the position adjusting motor 60 drives the rotating shaft of the driving sprocket 56 to rotate, driving the driving sprocket 56 to move left and right along the guiding chain 47, thereby driving the installation plate 54 to move left and right in reverse. The installation plate 54 drives the box placing plate 51 to move, and then drives the four support guide wheels 52 that are symmetrically arranged in pairs front and back to move along the upper end of the guide rail frame 44 on the same side. At the same time, the two left support guide wheels 52 drive the placing plate 50 to move left and right synchronously. A wire dragging chain 49 is arranged between the box placing plate 51 and the drag chain trough plate 48 for wire routing and supplying power to the photoelectric sensors 59 and the position adjusting motor 60. When moving to the leftmost and rightmost positions, the right support guide wheel 52 and the left placing plate 50 on the left side will abut against the limiters 45 on the same side for limiting to prevent falling. The box placing area is used to place a plurality of waste collecting boxes 6. The photoelectric sensors 59 are used to monitor the moving position of the box placing plate 51, so that the waste collecting boxes 6 are respectively aligned with the discharging conveyor track 2 for collecting different wastes. The placing plate 50 can be provided with material boxes as needed for collecting wastes.

[0051] The waste collecting box 6 is clamped inside the box placing area at the corresponding position. A plurality of lifting rings are arranged on the left and right sides of the upper end of the waste collecting box 6.

[0052] A number of hanging rings are used to lift and place the waste collection box 6, and the waste collection box 6 is clamped inside the box placement area at the corresponding position.

[0053] The working principle of the present invention: The casters 39 facilitate the movement of the discharging conveyor track machine 2, and it moves to the required position. Then, the lifting support feet 40 are adjusted. When the lifting support feet 40 rise, the casters 39 are lifted off the ground, and at this time, the position of the discharging conveyor track machine 2 is fixed. Adjust the adjusting rods on the two adjusting rod seats 46 to tighten the guiding chain 47, so that the driving sprocket 56 and the two supporting sprockets 57 are both in transmission cooperation with the guiding chain 47. The empty waste collection box 6 is lifted and placed and clamped inside the box placement area at the corresponding position through the hanging rings. The sorting and waste discharging mechanism 1 can drive a number of waste collection boxes 6 to move left and right. The external handling equipment transports the plate to be cut to the turning discharging platform 4 and the positioning platform mechanism 3. The limiting air cylinder 30 and the jacking and positioning assembly 31 are used to block and position the plate to be cut. That is, the telescopic end of the jacking air cylinder 32 expands and contracts, thereby driving the main body of the jacking air cylinder 32 to lift and lower in the reverse direction. The jacking air cylinder 32 drives the mounting vertical plate 34 to lift and lower, that is, drives the proximity sensor 33, the two bearing seats 38, the sliding limiting shaft 37, the touch control rod 35, the swing rod 36 and the ejecting rod to lift and lower synchronously, so that the swing rod 36 rises and falls from the avoidance hole, and then drives the ejecting rod to rise and fall. The telescopic end of the limiting air cylinder 30 extends out from the avoidance hole at the corresponding position, and the ejecting rod rises and extends out from the avoidance hole at the corresponding position. After the plate abuts against the ejecting rod, it pushes the swing rod 36 to rotate on the two bearing seats 38, so that the swing rod 36 slides on the sliding limiting shaft 37. The swing rod 36 presses the top position spring, and the swing rod 36 drives the touch control rod 35 to move. The touch control rod 35 abuts against the proximity sensor 33, controlling the equipment for placing the plate externally to stop pushing the plate, completing the positioning of the plate. After the positioning is completed, the jacking air cylinder 32 and the limiting air cylinder 30 descend and retract, and the top position spring drives the swing rod 36 to reset. At this time, the touch control rod 35 disengages from the proximity sensor 33, ensuring that the equipment for placing the plate externally is controlled to stop pushing the plate next time, and releasing the positioning of the plate to be cut. The external laser cutter head device cuts the plate to be cut by laser. During the cutting process, debris and dust will be 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 inside of the dust collection box 5. That is, the air outlet joint 12 is connected to the external exhaust fan, and the filter screen 13 is used for filtering and ventilation. A negative pressure is formed inside the filter box 10 to suck the debris and dust generated during cutting through the feeding box 11 into the inside of the filter box 10, and then fall into the waste collection drawer 9. The waste collection drawer 9 is pulled out regularly to clean the debris and dust inside the waste collection drawer 9. After each cutting process is completed, the cutting waste will fall onto the tipping discharge platform 4. After the same type of waste falls onto the tipping discharge platform 4, the tipping discharge platform 4 will tilt, that is, the telescopic ends of several lifting cylinders 17 will rise synchronously to lift the lifting frame 18. At this time, the lifting slider 19 slides inside the lifting slide base 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 lift synchronously and stably. When the flipping frame 20 descends to the waste discharging assembly, the flipping cylinder 23 retracts, driving the flipping frame 20 to rotate towards the waste discharging assembly between the two rotating seats 22, and the waste on the flipping brush plates 21 is tilted and poured out, sliding onto the waste discharging assembly. That is, the waste slides onto the inclined discharge chute hopper 24, stably slides onto the conveying track 42 of the discharge conveying track machine 2. The output shaft of the conveying motor 43 drives one of the track rollers to rotate, and the two track rollers cooperate with the conveying track 42 to drive the conveying track 42 to perform the conveying work. After the cutting waste falls onto the conveying track 42, it is conveyed and sent into one of the waste collection boxes 6. When another type of waste is cut, the output shaft of the position adjustment motor 60 drives the rotating shaft of the driving sprocket 56 to rotate, driving the driving sprocket 56 to move left and right along the guiding chain 47, thereby driving the mounting plate 54 to move left and right in reverse. The mounting plate 54 drives the box placing plate 51 to move, and then drives the four support guide wheels 52 arranged symmetrically in pairs front and back to move along the upper end of the guide rail frame 44 on the same side. At the same time, the two left support guide wheels 52 drive the placing plate 50 to move left and right synchronously. There is a wire dragging chain 49 between the box placing plate 51 and the drag chain groove plate 48 for wire routing to supply power to the photoelectric sensor 59 and the position adjustment motor 60. When moving to the leftmost and rightmost positions, the right support guide wheel 52 and the left placing plate 50 will contact the limiters 45 on the same side for limiting to prevent falling. The box placing area is used to place several waste collection boxes 6. The photoelectric sensor 59 is used to monitor the moving position of the box placing plate 51, and the switching makes another waste collection box 6 face the discharge conveying track machine 2 for collecting different wastes and sorting and discharging the wastes by category. After the waste collection box 6 is full, several lifting rings are used to lift away the waste collection box 6 and then replace it with a new empty waste collection box 6 to continue sorting and discharging the wastes by category.

[0054] In summary, by connecting the dust suction box 5 to an external exhaust fan, the debris and soot are sucked into the interior of the dust suction box 5, and the interior debris and soot are cleaned regularly. Through the cooperation of the tipping discharge platform 4 and the positioning platform mechanism 3, it is used to stably support and convey the plate to be cut. The tipping discharge platform 4 will tilt to pour the waste onto the waste discharging assembly obliquely, and the waste falls onto the discharge conveying track machine 2 along the waste discharging assembly. Through the cooperation of the waste discharging assembly and the discharge conveying track machine 2, the stable conveying and discharging of the waste are realized. By cooperating with the positioning platform mechanism 3, the limit cylinder 31 and the jacking and positioning assembly 31, it is used to stably and quickly position the plate to be cut, ensuring accurate cutting. By cooperating with the discharging conveyor track machine 2 and a number of waste collection boxes 6, it realizes driving the number of waste collection boxes 6 to move left and right, switching the positions of the waste collection boxes 6, and sorting and collecting the discharged waste by category.
