Abstract
Description
Technical Field
[0001] This application belongs to the field of materials processing technology, specifically relating to a debris cleaning device and a sheet metal processing system. Background Technology
[0002] After milling the edges of sheet metal workpieces, the milling equipment includes two sets of milling cutters arranged opposite each other, with iron brushes installed at each set of milling cutters. As the workpiece passes between the two sets of milling cutters, most of the metal chips milled off the workpiece during the milling process can be cleaned by the iron brushes. However, a small amount of debris will still adhere to the workpiece and move with it. When multiple workpieces are stacked, the presence of debris can easily cause indentations in the workpiece, resulting in unqualified surface quality.
[0003] Currently, the method for cleaning debris attached to workpieces is manual sweeping, which poses a safety hazard as the metal debris comes into direct contact with the human body. Summary of the Invention
[0004] The purpose of this application is to provide a debris cleaning device and a sheet metal processing system that mechanically cleans debris attached to workpieces, reducing manual intervention and lowering safety hazards.
[0005] To achieve the above objectives, this application provides a debris cleaning device, including a conveying assembly, a cleaning brush disposed on the conveying assembly, and a blowing assembly disposed on the side of the conveying assembly. The cleaning brush and the blowing assembly are arranged sequentially along the conveying direction of the conveying assembly. The conveying assembly has a conveying surface for placing workpieces. The blowing assembly has an air outlet facing the conveying surface, and the angle and height of the air outlet relative to the conveying surface are adjustable.
[0006] In some embodiments, the purging assembly includes a telescopic frame fixed to one side of the conveying assembly and a fan rotatably mounted on the telescopic frame.
[0007] In some embodiments, the purging assembly further includes a connecting frame rotatably connected to the telescopic frame and a locking member connected to the connecting frame. The locking member is used to lock the connecting frame to a predetermined angular position formed after it rotates relative to the telescopic frame. A blower is connected to the locking member to follow the locking member in rotating relative to the telescopic frame.
[0008] In some embodiments, the purging assembly also includes a nozzle that is sealed to the outlet of the blower, the outlet of the nozzle being formed as an air outlet, and a tapering ventilation channel being formed inside the nozzle.
[0009] In some implementations, a discharge gap is formed on the conveying assembly for the debris to fall off.
[0010] In some embodiments, the conveying assembly includes a support frame and a plurality of conveying rollers rotatably mounted on the support frame. The plurality of conveying rollers are arranged sequentially at intervals along the conveying direction, and a material drop gap is formed between two adjacent conveying rollers.
[0011] In some embodiments, the conveying assembly further includes a guide plate disposed below the conveying roller, and the debris cleaning device further includes a collection box disposed below the conveying roller, with the guide plate inclined from the support frame to the collection box.
[0012] In some embodiments, the conveying assembly also includes a baffle mounted on a support frame, the baffle being located on the side of the conveying roller and facing the air outlet of the blowing assembly, to block debris blown off by the blowing assembly.
[0013] In some embodiments, the debris cleaning device further includes a first photoelectric switch and a second photoelectric switch disposed above the conveying roller, which are spaced apart along the conveying direction and are both electrically connected to the blowing assembly. When the first photoelectric switch is triggered, the blowing assembly is activated, and when the second photoelectric switch is triggered, the blowing assembly is deactivated.
[0014] A second aspect of this application provides a sheet metal processing system, including a milling machine and the aforementioned chip removal device, wherein the chip removal device is disposed downstream of the milling machine.
[0015] With the above technical solution, the milled workpiece is conveyed by a conveying assembly. During conveying, a cleaning brush first removes the debris adhering to the workpiece surface, and then air is blown from the outlet of the blowing assembly to remove any remaining debris from the workpiece, ensuring that all debris is removed. Since different workpieces may have different thicknesses, the angle and height of the air outlet are adjusted to ensure that the outlet is always directly facing the workpiece, guaranteeing the best blowing effect. No manual intervention is required during the debris removal process, avoiding contact between workers and metal debris and reducing safety hazards.
[0016] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0028] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0029] Please refer to Figures 1 to 6 This application provides a debris cleaning device, including a conveying assembly 10, a cleaning brush 20 disposed on the conveying assembly 10, and a blowing assembly 30 disposed on the side of the conveying assembly 10. The cleaning brush 20 and the blowing assembly 30 are arranged sequentially along the conveying direction of the conveying assembly 10. The conveying assembly 10 has a conveying surface for placing a workpiece 9. The blowing assembly 30 has an air outlet 31 facing the conveying surface, and the angle and height of the air outlet 31 relative to the conveying surface are adjustable.
[0030] Workpiece 9 is conveyed by conveying assembly 10. As workpiece 9 passes through cleaning brush 20, the cleaning brush 20 removes debris adhering to its surface. After cleaning by the cleaning brush 20, air is output from the outlet 31 of blowing assembly 30, blowing away any remaining debris from the surface of workpiece 9. The cleaning brush 20 and blowing assembly 30 perform two-stage cleaning: the cleaning brush 20 performs primary cleaning by brushing, and the blowing assembly 30 performs secondary cleaning by blowing, ensuring that all debris on the surface of workpiece 9 is completely removed, minimizing or eliminating debris residue. No manual intervention is required during the debris removal process on workpiece 9, preventing safety issues caused by debris contact with the human body and reducing labor costs. Compared to manual cleaning, the debris cleaning device in this application can clean the debris attached to the workpiece 9 during the conveying process of the conveying component 10, thereby improving the debris cleaning efficiency. Furthermore, during manual cleaning, the milling equipment needs to be stopped, while the debris cleaning device in this application can ensure that the workpiece 9 continues to move without affecting the milling equipment to perform milling operations on the next workpiece 9, thus improving the milling efficiency.
[0031] The cleaning brush 20 extends in a direction perpendicular to the conveying direction of the conveying assembly 10, so as to... Figure 1 The directions shown in the figure are described as follows: the arrow in the figure indicates the conveying direction of workpiece 9. The extension length (vertical dimension) of cleaning brush 20 is greater than or equal to the width (vertical dimension) of conveying component 10, so that when workpiece 9 passes through cleaning brush 20, cleaning brush 20 can sweep across the entire width (vertical dimension) of workpiece 9, ensuring that the entire upper surface of workpiece 9 is cleaned by cleaning brush 20 after passing through it, thus ensuring the best cleaning effect.
[0032] Please refer to Figure 2 and Figure 3 In some embodiments, the purging assembly 30 includes a telescopic frame 32 fixed to one side of the conveying assembly 10 and a fan 33 rotatably mounted on the telescopic frame 32.
[0033] The telescopic frame 32 can extend and retract to adjust the height of the fan 33. The fan 33 can rotate relative to the telescopic frame 32 to adjust its angle. When the thickness of the workpiece 9 increases, the telescopic frame 32 extends, causing the fan 33 to rise. Simultaneously, the air outlet 31 also rises. At this time, in order for the gas output from the air outlet 31 to blow onto the surface of the workpiece 9, the air is directed towards the workpiece 9 in a direction close to it. Figure 2Rotate the fan 33 counterclockwise so that the air outlet 31 faces the workpiece 9; when the thickness of the workpiece 9 decreases, the telescopic frame 32 shortens, driving the fan 33 to lower, and at the same time the air outlet 31 will also lower, and the angle between the air outlet 31 and the surface of the workpiece 9 is small. At this time, in order to ensure that the air output from the air outlet 31 can blow on the entire surface of the workpiece 9, rotate the fan 33 in a direction away from the workpiece 9. Figure 2 Rotate the fan 33 clockwise to make the angle between the air outlet 31 and the surface of the workpiece 9 at a suitable angle.
[0034] Please continue reading. Figure 2 and Figure 3 In some embodiments, the purging assembly 30 further includes a connecting frame 34 rotatably connected to the telescopic frame 32 and a locking member 35 connected to the connecting frame 34. The locking member 35 is used to lock the connecting frame 34 to a predetermined angular position formed after it rotates relative to the telescopic frame 32. The blower 33 is connected to the locking member 35 to follow the locking member 35 in rotating relative to the telescopic frame 32.
[0035] The connecting frame 34 rotates relative to the telescopic frame 32, driving the fan 33 to rotate. After the fan 33 rotates to the air outlet 31 in the appropriate position, the locking component 35 locks the connecting frame 34 and the telescopic frame 32, preventing them from rotating relative to each other, thus fixing the air outlet 31 in that position.
[0036] The connecting frame 34 is a rod-shaped structure. Its top end is connected to the fan 33, and its bottom end is connected to the telescopic frame 32. The telescopic frame 32 includes an outer tube 321 fixed on the ground on the side of the conveying assembly 10 and an inner rod 322 inserted into the outer tube 321. The relative fixation of the outer tube 321 and the inner rod 322 is achieved by inserting bolts into the outer tube 321 and tightening them against the inner rod 322. The top end of the inner rod 322 is hinged to the bottom end of the connecting frame 34, for example, by a hinge. The hinge point of the two is located on the side of the two closer to the conveying assembly 10, so as to realize the relative rotation of the two.
[0037] like Figure 4 As shown, the locking component 35 includes a first adjusting plate 351 connected to the connecting frame 34, a second adjusting plate 352 connected to the telescopic frame 32, and a locking pin 353 connecting the first adjusting plate 351 and the second adjusting plate 352. The first adjusting plate 351 has an arc-shaped first adjusting hole 3511, and the second adjusting plate 352 has an arc-shaped second adjusting hole 3521 communicating with the first adjusting hole 3511. The first adjusting hole 3511 and the second adjusting hole 3521 have the same curvature, forming a semi-circular shape. The locking pin 353 passes through the first adjusting hole 3511 and the second adjusting hole 3521. Alternatively, the first adjusting plate 351 and the second adjusting plate 352 can also be arc-shaped plates with the same curvature. Figure 4Described in the indicated orientation, the upper end of the first adjusting plate 351 is fixedly connected to the connecting frame 34, and the lower end is located in front of the second adjusting plate 352. The upper end of the second adjusting plate 352 is located behind the first adjusting plate 351, and the lower end is fixedly connected to the inner rod 322. The locking pin 353 can be one or more bolts and nuts. The bolts pass through the first adjusting hole 3511 and the second adjusting hole 3521 in sequence. The first adjusting plate 351 and the second adjusting plate 352 are fixedly connected by tightening the nuts. When it is necessary to adjust the angle of the fan 33, the nuts are loosened, and the first adjusting plate 351 and the second adjusting plate 352 can move relative to each other. After the fan 33 rotates to the appropriate angle, the nuts are tightened again to lock the fan 33 in that position.
[0038] In addition, the purging assembly 30 also includes a switch 331 for controlling the start and stop of the fan 33, and the switch 331 is fixed on the connecting bracket 34.
[0039] Please continue reading. Figure 2 and Figure 3 In some embodiments, the purging assembly 30 further includes a nozzle 36 sealed to the outlet of the blower 33, the outlet of the nozzle 36 being formed as an air outlet 31, and a tapered ventilation channel being formed inside the nozzle 36.
[0040] The gas output from the outlet of the blower 33 enters the ventilation channel inside the nozzle 36 and flows along the ventilation channel to be discharged from the outlet 31. The gradually narrowing ventilation channel can increase the gas flow rate, thereby enhancing the driving force of the gas on the debris attached to the workpiece 9 and increasing the blowing effect of the blowing assembly 30.
[0041] Please refer to Figure 1 and Figure 5 In some embodiments, the conveying assembly 10 has a discharge gap 11 for the debris to fall into.
[0042] After the cleaning brush 20 sweeps away the debris attached to the workpiece 9, the debris on the cleaning brush 20 will fall off after the workpiece 9 leaves the cleaning brush 20 and be discharged from the material discharge gap 11 into the conveying assembly 10. Similarly, the debris blown off the workpiece 9 by the blowing assembly 30 can also be discharged from the material discharge gap 11 into the conveying assembly 10.
[0043] Please continue to refer to Figure 1 and Figure 5 In some embodiments, the conveying assembly 10 includes a support frame 12 and a plurality of conveying rollers 13 rotatably mounted on the support frame 12. The plurality of conveying rollers 13 are arranged sequentially at intervals along the conveying direction, and a material drop gap 11 is formed between two adjacent conveying rollers 13.
[0044] Since workpiece 9 has a plate-like structure, it can be transported using conveyor rollers 13. The gaps between the conveyor rollers 13 create a material drop gap 11 for debris to pass through, eliminating the need for a separate material drop gap 11. The conveyor rollers 13 are driven by a motor in conjunction with a chain drive.
[0045] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the conveying assembly 10 further includes a guide plate 14 disposed below the conveying roller 13, and the debris cleaning device further includes a collection box 40 disposed below the conveying roller 13. The guide plate 14 is inclined from the support frame 12 to the collection box 40.
[0046] Debris falling from the discharge gap 11 enters the guide plate 14 and slides along it into the collection box 40. The inclined surface of the guide plate 14 allows the debris to slide under the influence of gravity. The guide plate 14 forms a funnel-shaped structure, which can be formed by multiple planar guide plates 14 or by a single funnel-shaped guide plate 14. A guiding area is formed within this funnel-shaped structure, covering directly below the cleaning brush 20 and the air outlet 31. This allows debris falling from the cleaning brush 20 and debris blown off by the fan 33 to pass through the discharge gap 11 and fall onto the guide plate 14. The conveying direction is horizontal, and the angle between the side of the guide plate 14 away from the guiding area and the horizontal plane is 97° to ensure optimal guiding effect. The guide plate can be a sheet metal part.
[0047] In addition, the collection box 40 is designed as a trolley with a push-pull handle on the side and casters at the bottom. When the collection box 40 needs to be cleaned, it can be moved out of the conveying assembly 10 by pushing and pulling the handle, making it easy to clean the debris inside the collection box 40.
[0048] Please refer to Figure 6 In some embodiments, the conveying assembly 10 further includes a baffle 15 disposed on the support frame 12, the baffle 15 being located on the side of the conveying roller 13 and facing the air outlet 31 of the blowing assembly 30, to block debris blown off by the blowing assembly 30.
[0049] Among them, the baffle 15 protrudes above the conveying assembly 10. The baffle 15 can be vertically fixed above the support frame 12 by bolts. Two baffles 15 can be set opposite each other. The baffle 15 near the blowing assembly 30 has an opening for the insertion of the air nozzle 36 to avoid the baffle 15 blocking the air blown out of the air outlet 31 of the air nozzle 36. The size of the opening is larger than the longitudinal cross-sectional size of the air nozzle 36 to provide sufficient space for the rotation of the air nozzle 36 relative to the telescopic frame 32. A guard plate 16 is also horizontally set above the cleaning brush 20. The guard plate 16 is fixed above the two baffles 15. The debris blown off by the blowing assembly 30 can be blocked by the baffles 15 and the guard plate 16 to prevent debris from splashing and polluting the surrounding environment. After the blower 33 stops, the debris on the baffle 15 can fall off under its own gravity and slide along the guide plate 14 into the collection box 40 after passing through the material drop gap 11.
[0050] In some embodiments, the debris cleaning device further includes a first photoelectric switch 51 and a second photoelectric switch 52 disposed above the conveying roller 13. The two are spaced apart along the conveying direction and are both electrically connected to the blowing assembly 30. When the first photoelectric switch 51 is triggered, the blowing assembly 30 is activated, and when the second photoelectric switch 52 is triggered, the blowing assembly 30 is stopped.
[0051] The cleaning brush 20 and the air outlet 31 are located between the first photoelectric switch 51 and the second photoelectric switch 52. After the workpiece 9 passes the first photoelectric switch 51 from the front, the first photoelectric switch 51 is triggered, starting the fan 33. The fan 33 generates gas and blows it out from the air outlet 31 of the nozzle 36. At this time, the workpiece 9 has not yet entered the cleaning range of the air outlet 31. Starting the fan 33 in advance ensures that the gas output from the air outlet 31 is stable when the workpiece 9 enters the cleaning range, avoiding gas instability caused by the instant the fan 33 starts, which would affect the cleaning effect. After the workpiece 9 passes the second photoelectric switch 52 from the front, the second photoelectric switch 52 is not triggered. After the workpiece 9 passes the second photoelectric switch 52 from the rear, the second photoelectric switch 52 is triggered, stopping the fan 33. At this time, the workpiece 9 has passed the cleaning brush 20 and the air outlet 31, and the debris attached to the workpiece 9 has been cleaned. Stopping the fan 33 can achieve energy saving and emission reduction. The triggering method of the second photoelectric switch 52 can be achieved by electrically connecting it to the controller, or a photoelectric switch type that meets the requirements can be selected.
[0052] The first photoelectric switch 51 and the second photoelectric switch 52 are fixed on the side of the guard plate 16 facing the conveyor roller 13, i.e., the lower surface.
[0053] A second aspect of this application provides a sheet metal processing system, including a milling machine and the aforementioned chip removal device, wherein the chip removal device is disposed downstream of the milling machine.
