Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and in particular to a numerical control cutting automatic synchronous visual dust removal device. Background Art

[0002] During the CNC cutting process, a large amount of dust is generated. This dust not only poses a serious threat to the health of operators, and long-term inhalation may lead to occupational diseases such as pneumoconiosis, but also the dust diffuses in the workshop and easily deposits on key components of the equipment, accelerating equipment wear, reducing equipment life and cutting accuracy.

[0003] Traditional CNC cutting dust removal systems suffer from numerous drawbacks. For one thing, most dust removal equipment cannot automatically synchronize with the CNC cutting process. When cutting begins, the dust removal system fails to activate immediately, causing a large amount of dust generated during the initial cutting phase to escape into the air. Furthermore, after cutting is complete, the dust removal system fails to shut down promptly, resulting in energy waste. Furthermore, existing dust removal systems lack visual indicators, making it difficult for operators to intuitively understand the internal working conditions of the dust removal system, such as whether the filter element is clogged or the dust collection chamber is full. This leads to untimely equipment maintenance, further compromising dust removal effectiveness. Summary of the Invention

[0035] Reference Figures 1-10The present invention proposes a CNC cutting automatic synchronous visual dust removal device, comprising an operating table 1, a gantry movable frame 2 is slidably mounted on the operating table 1, the gantry movable frame 2 slides horizontally on the operating table 1 through a No. 1 electric slide rail, a hydraulic rod 3 is slidably mounted on the gantry movable frame 2, the hydraulic rod 3 slides longitudinally on the gantry movable frame 2 through a No. 2 electric slide rail, the hydraulic rod 3 can drive a plasma cutting head 4 and a color-changing transparent cover 5 to move vertically, and can realize the movement of the plasma cutting head 4 according to programming, the plasma cutting head 4 and the color-changing transparent cover 5 are mounted on the output shaft of the hydraulic rod 3, and a silver halide substance (such as silver chloride) is arranged in the color-changing transparent cover 5. , silver bromide), its working principle is similar to that of color-changing sunglasses (under ultraviolet light, silver halide will undergo a photodecomposition reaction to produce silver atoms and halogen atoms. When the light is weakened, under the action of heat, the silver atoms and halogen atoms will recombine to form silver halide, and the color of the color-changing transparent cover 5 will gradually become lighter and return to a relatively transparent state). The depth of the color of the color-changing transparent cover 5 can be changed according to the change of the strong light emitted during cutting, which can facilitate the staff to simply observe the internal cutting situation. The color-changing transparent cover 5 is covered on the plasma cutting head 4. When the cutting operation is carried out, the bottom of the color-changing transparent cover 5 is almost in contact with the top surface of the metal plate, and the color-changing transparent cover 5 is relatively transparent. A dust extraction mechanism No. 1 is installed on the transparent cover 5. When performing plasma cutting operations, it is necessary to first adjust the position of the metal plate and fix the metal plate to reduce the movement of the metal plate during the cutting process and ensure the quality of the cutting mouth. The dust extraction mechanism No. 1 sucks in the debris generated by the cutting to achieve the effect of dust removal. A camera No. 1 is installed in the color-changing transparent cover 5. The camera No. 1 can also display the cutting situation in the color-changing transparent cover 5 on the display to achieve visualization; a plurality of telescopic holes are provided on the top surface of the operating table 1, and a support column 6 is installed in the telescopic hole for lifting and lowering. A constant force lifting mechanism is installed in the lifting hole. The constant force lifting mechanism is used to lift the support column 6 from the lifting hole The support column 6 is lifted up in the hole, and the constant force lifting mechanism supports the support column 6. Since the force exerted by the constant force lifting mechanism on the support column 6 is always consistent, when the metal plate (the metal plate is normally evenly distributed) is plasma cut, when the thickness of the metal plate exceeds the standard, the weight of the metal plate will also increase with the overweight, and the pressure on the single support column 6 will also increase accordingly. When the thickness of the metal plate exceeds the standard, the pressure on the single support column 6 will also exceed the standard, and the metal plate will press the support column 6 down synchronously. At this time, the staff can know that the thickness of the metal plate exceeds the standard, which is convenient for the staff to remove the metal plate with excessive thickness in time, avoiding cutting of metal plates that exceed the specifications;A lower dust suction plate 7 is slidably mounted on the operating table 1, and the top opening of the lower dust suction plate 7 almost fits the bottom surface of the metal plate. Due to the setting of the constant force lifting mechanism, as long as the thickness of the metal plate does not exceed the standard, the support column 6 will not drop, so the height of the lower dust suction plate 7 can be ensured, and there is no need to adjust the height of the lower dust suction plate 7. A second dust suction mechanism is installed on the lower dust suction plate 7, and the lower dust suction plate 7 moves synchronously with the plasma cutting head 4. When plasma cutting is performed, the molten and vaporized metal is blown away from the cutting area by high-speed flowing gas. In this process, a large amount of metal will be blown to the bottom surface of the metal plate. Therefore, the lower dust suction plate 7 and the second dust suction mechanism are set. Since the plasma cutting head 4 is movable at any time, it is necessary to use a synchronous motion control system (a synchronous motion control system is generally composed of a controller, a driver, a sensor, and an actuator. The controller sends instructions to the driver according to the preset motion trajectory and synchronization requirements. The driver drives the actuator to move the object, and the sensor monitors the object's motion state in real time and transmits feedback information to the controller so that the controller can make real-time adjustments and optimizations, thereby achieving precise synchronous movement of two or more objects). This enables the lower dust collection plate 7 to move synchronously with the plasma cutting head 4 and perform dust removal operations synchronized with cutting. In actual practice, when plasma cutting metal plates, most of the debris generated is blown away by the high-speed airflow (under the metal plate). Therefore, a driving mechanism is installed on the operating table 1. The driving mechanism is used to drive the lower dust collection plate 7 to move on the operating table 1. The driving mechanism needs to drive the lower dust collection plate 7 to move synchronously with the plasma cutting head 4, so that the debris generated on both sides of the metal plate can be removed during cutting. This ensures that the dust removal device can be synchronized with the cutting operation, reducing energy waste and reducing the harm caused by dust escaping into the air.

[0036] like Figure 2 and Figure 8As shown in, the constant force lifting mechanism includes a ladder block 8, a constant force spring 9 and a lifting rod 10; the ladder block 8 is fixedly connected to the bottom end of the support column 6, and a lifting groove that slides with the ladder block 8 is provided in the operating table 1. The cross-sectional area of the ladder block 8 is larger than the cross-sectional area of the support column 6. The ladder block 8 can prevent the support column 6 from escaping from the lifting hole to ensure that the top of the support column 6 remains on a horizontal plane. A rotating groove is also provided in the operating table 1. The inner ring end of the constant force spring 9 is fixedly installed in the rotating groove, and the outer ring end of the constant force spring 9 is fixedly connected to the bottom end of the lifting rod 10. The other end of the lifting rod 10 passes through the operating table 1 and is fixedly connected to the bottom end of the ladder block 8. Due to the characteristics of the constant force spring 9, the constant force spring 9 produces an upward force on the support column 6 The force acting on the metal plate is always consistent. Since the metal plate is usually of uniform texture (single material), when the area of the metal plate remains unchanged, the number of support columns 6 used to support the metal plate is consistent. Therefore, the pressure on a single support column 6 increases with the thickness of the metal plate. When the thickness of the metal plate exceeds the specification, the pressure on the single support column 6 exceeds the force applied by the constant-force spring 9. Therefore, the metal plate will press the support column 6 down. When the metal plate drops, the staff can know that the thickness of the metal plate exceeds the standard and take timely measures. In addition, when cutting the metal plate, after the lower dust suction plate 7 moves, the corresponding descending support column 6 will rise and collide with the metal plate, which can shake off the debris on the metal plate and ensure the dust removal effect.

[0037] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown in FIG, the dust extraction mechanism No. 1 includes a dust extraction box No. 11, a guide partition 12, a V-shaped filter 13 and a fan No. 14; a guide channel 15 (see FIG. 15 ) is provided in the color-changing transparent cover 5 and is connected to the dust extraction box No. 11. Figure 4In the middle, under the exhaust action of the No. 1 fan 14, the air on the metal plate flows along the top surface of the metal plate through the guide channel 15. The No. 1 dust box 11 is installed on the top of the color-changing transparent cover 5. The bottom of the No. 1 dust box 11 is connected to the color-changing transparent cover 5. The guide partition 12 is installed in the No. 1 dust box 11. The side wall of the guide partition 12 and the inner wall of the No. 1 dust box 11 form a material storage trough; the V-shaped filter 13 is installed in the No. 1 dust box 11, and the V-shaped filter 13 Located above the guide partition 12, the No. 1 fan 14 is installed in the No. 1 dust box 11, the No. 1 fan 14 is located above the V-shaped filter 13, and the No. 1 fan 14 is located directly above the storage trough. The No. 1 dust extraction mechanism also includes an isolation plate 16 and an impeller 17; the isolation plate 16 is connected to the side of the V-shaped filter 13, and the isolation plate 16 is located directly above the storage trough; the impeller 17 is rotatably installed in the No. 1 dust box 11, and the blades of the impeller 17 can scrape the bottom of the isolation plate 16. When the dust is removed from the hopper 14, the dust collector 10 is moved to the hopper 15 by the impeller 17. When the dust is removed from the hopper 14, the dust collector 10 is moved to the hopper 15 by the impeller 17. When the dust is removed from the hopper 14, the dust collector 10 is moved to the hopper 15 by the impeller 17.

[0038] like Figure 1 and Figure 9As shown in the figure, the No. 2 dust extraction mechanism includes a No. 2 dust extraction box 18, a built-in box 19, an inverted V filter 20 and a No. 2 fan 21; the No. 2 dust extraction box 18 is installed at the bottom of the lower dust suction plate 7, the top of the No. 2 dust extraction box 18 is connected to the lower dust suction plate 7, the built-in box 19 is installed in the No. 2 dust extraction box 18, the side wall of the built-in box 19 and the inner wall of the No. 2 dust extraction box 18 form a waste chip groove, the inverted V filter 20 is installed on the top of the built-in box 19, the inverted V filter 20 can block the top opening of the built-in box 19, the No. 2 fan 21 is installed in the built-in box 19, and the built-in box 19 is provided with an air outlet connected to the outside world. During the dust removal operation, the debris blown down by the high-speed airflow will enter the lower dust suction plate 7. At the same time, the No. 2 fan 21 will work to draw the debris entering the lower dust suction plate 7 into the No. 2 dust box 18, and the debris will be filtered out through the inverted V filter 20. The debris hits the inverted V filter 20, and the debris will slide to both sides along the inclined surface of the inverted V filter 20 and enter the waste chip trough. A baffle is provided above the waste chip trough to reduce the impact of the fast-flowing airflow on the debris in the debris trough, ensuring the stability of the debris in the debris trough. In addition, the lower dust suction plate 7 is almost attached to the bottom surface of the metal plate to ensure the dust removal effect.

[0039] like Figure 1 and Figure 2 As shown in , a plurality of support columns 6 are arranged in a matrix on the top surface of the operating table 1, and the projection of the lower dust suction plate 7 on the operating table 1 can cover the square formed by the four adjacent support columns 6. A avoidance mechanism is installed on the operating table 1. When the lower dust suction plate 7 moves synchronously with the plasma cutting head 4, the avoidance mechanism can drive the support columns 6 at the corresponding positions to descend to the avoidance position of the lower dust suction plate 7. In actual practice, the cutting pattern is controlled by CNC programming during plasma cutting. It is assumed that when cutting a circle, the area of the circle is larger than the opening size of the lower dust suction plate 7, when the opening size of the lower dust suction plate 7 is smaller than the square area formed by the four support columns 6, when the plasma cutting head 4 cuts along the line connecting the support columns 6 (due to the setting of the support columns 6, the moving trajectory of the lower dust suction plate 7 is limited), the lower dust suction plate 7 is moved. The disk 7 cannot be located directly below the cutting position and the dust removal operation cannot be completed. Therefore, the opening size of the lower dust suction disk 7 is set to be larger than the square area formed by the line connecting the ends of the four support columns 6. During plasma cutting, it can ensure that the lower dust suction disk 7 moves with the movement of the plasma cutting head 4, thereby ensuring the dust removal effect. When the lower dust suction disk 7 reaches the cutting position, the support columns 6 at the corresponding positions are driven to descend by the avoidance mechanism to avoid, ensuring the movement of the lower dust suction disk 7, thereby ensuring the dust removal effect. After the lower dust suction disk 7 passes, the force of the constant force spring 9 acts on the support columns 6, causing the support columns 6 to rise, and the top of the support columns 6 hits the bottom surface of the metal plate, causing the metal plate to vibrate. The vibration can shake off the debris on the metal plate, making the dust removal effect better.

[0040] like Figure 1、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10 As shown in, the avoidance mechanism includes a avoidance rod 22, a driving block 23, a trapezoidal block 24 and a return spring 25; a grid groove 26 is provided on the top surface of the operating table 1, and the number of avoidance rods 22 is four. The four avoidance rods 22 and the No. 2 dust box 18 form a cross structure. The spacing between the two avoidance rods 22 at opposite corners is the same as the width of the two grids of the grid groove 26. The four avoidance rods 22 are respectively vertically installed in the middle position of the four sides of the lower dust suction plate 7, and the avoidance rod 22 slides in the grid groove 26. The inner walls of the lifting groove are provided with a transverse groove that slides with the driving block 23. The end of the driving block 23 can slide with the inclined surface of the ladder block 8. The inner wall of the grid groove 26 is provided with a limiting groove that slides with the trapezoidal block 24. The end of the driving block 23 away from the ladder block 8 is fixedly connected to the trapezoidal block 24, and the avoidance rod 22 can slide with the trapezoidal block 24. The side sliding cooperation, in actual operation, the No. 2 dust box 18 moves along the grid groove 26, and the No. 2 dust box 18 will drive the lower dust plate 7 to move synchronously. When the lower dust plate 7 moves, it will drive the four avoidance rods 22 to move synchronously. The avoidance rod 22 first slides with the inclined surface of the trapezoidal block 24, and the avoidance rod 22 drives the two driving blocks 23 to move away from each other on both sides. The ends of the driving blocks 23 slide against the inclined surface of the ladder block 8, so that the ladder block 8 falls in the lifting groove, and the ladder block 8 drives the support column 6 to fall synchronously, completing the avoidance of the lower dust plate 7. The return spring 25 is located in the limit groove, and the two ends of the return spring 25 are respectively connected to the trapezoidal block 24 and the inner wall of the limit groove. The rebound effect of the return spring 25 can drive the trapezoidal block 24 to slide and reset and drive the driving block 23 to reset synchronously, thereby ensuring the lifting and reset of the support column 6.

[0041] like Figure 1 、 Figure 2 and Figure 9 As shown in the figure, the driving mechanism includes an electric grid track 27 and a supporting connecting rod 28; the electric grid track 27 is installed in the grid groove 26, and the two ends of the supporting connecting rod 28 are respectively connected to the slider of the electric grid track 27 and the bottom end of the No. 2 dust box 18. The electric grid track 27 drives the supporting connecting rod 28 and the No. 2 dust box 18 to move along the grid groove 26, thereby driving the movement of the lower dust suction plate 7.
