Description

Technical Field

[0001] The invention relates to the field of plate processing equipment, and more specifically, to a debris collection device for a numerically controlled cutting machine. Background Art

[0002] The CNC cutting machine is a device equipped with CNC programs to execute operations. It uses CNC technology to cut and process materials. Workers input the size data required for cutting on a PC or touch screen, start the machine to run automatically, and realize automatic material grabbing and plate feeding, automatic calibration and positioning for precision cutting and other operations.

[0003] When a CNC cutting machine performs operations such as cutting a plate, debris will be generated. The existing patent (Chinese utility model patent with announcement number CN213196701U) discloses a debris collection device for a CNC cutting machine, which can intercept the debris by setting a baffle plate and absorb the debris by setting a dust suction structure, thereby realizing the collection of the debris, but cannot clean and collect the debris that falls on the plate surface and remains in the plate cutting groove;

[0004] In order to clean and collect the debris on the surface of the plate and the debris remaining in the cutting groove of the plate, a dust hood is currently installed on the cutting head of the CNC cutting machine, and the dust hood is connected to the dust collection device. The brush at the lower end of the dust hood can block the debris splashed during cutting, and the debris splashed in the dust hood is sucked into the dust collection device, reducing the amount of debris falling on the surface of the plate. At the same time, the brush can also clean the debris on the surface of the plate and the debris remaining in the cutting groove of the plate. However, when the brush sweeps out the debris remaining in the cutting groove, the debris in the cutting groove will accumulate together and move from the cutting groove to the surface of the plate, which will cause the debris on the surface of the plate to gradually increase and the thickness of the debris to gradually increase, resulting in a poor cleaning effect of the brush. The brush cannot thoroughly clean the debris in the cutting groove and on the surface of the plate. Even after brushing with the brush, some debris will still remain in the groove and surface of the plate, which needs to be cleaned again. Summary of the invention

[0011] Furthermore, the jet part includes a shell rotatably connected to the inside of the rod body, a hose located inside the shell and connected to the pipeline interface, a frame connected to the inside of the shell, a jet head rotatably connected to the frame, and a rotary joint connected to the input end of the jet head, the inner tube of the rotary joint is fixedly connected to the input end of the jet head, and the input end of the rotary joint is connected to the other end of the hose.

[0012] Furthermore, a chip removal enhancement portion is provided inside the frame, and the chip removal enhancement portion includes a motor 1 fixedly connected to the inner wall of the frame, a gear 2 rotatably connected to the inner wall of the frame, and a gear 3 fixedly connected to the outside of the nozzle and meshing with the gear 2, and the output shaft of the motor 1 is fixedly connected to one side of the gear 2.

[0013] Furthermore, a flange 1 is fixedly connected to the outer surface of the nozzle, a movable groove for accommodating the movement of the nozzle is opened on one side of the shell, and two flanges 2 are symmetrically fixedly connected to the inner wall of the movable groove, support columns are fixedly connected to the upper and lower ends of the frame, and the other ends of the two support columns are rotatably connected to the inner wall of the shell, and two sets of tension springs are symmetrically fixedly connected to the two sides of the frame, and the other ends of the tension springs are connected to the inner wall of the shell.

[0014] Furthermore, an atomizer and a venturi tube are fixedly connected to the upper end of the seat body, and the output end of the atomizer is connected to the throat input end of the venturi tube through a pipe, the diffusion end of the venturi tube is connected to the extension end of the gas pipeline, and the input end of the venturi tube is used to connect to the air pipe.

[0015] Furthermore, it also includes a reset component, and the reset component includes three guide columns fixedly connected to the upper end of the seat body, a second motor fixedly connected to the lower end of the seat body, a screw rod rotatably connected to the inside of the seat body, and a movable plate movably sleeved on the outside of the guide columns, and the screw rod is screwed in the movable plate, the output shaft of the second motor is fixedly connected to one end of the screw rod, and the movable plate is located between the sleeve and the seat body.

[0016] Furthermore, a sensor is fixedly connected to the lower end of the sleeve, and the sensor is used to detect whether the sleeve is in contact with the movable plate.

[0017] Furthermore, a avoidance groove is provided inside the seat body to facilitate the passage of the shaft head.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In this scheme, a chip removal unit is movably arranged inside the seat body. When the cutting drill moves to cut the plate, the spring can push the lower end of the rod body into the groove cut in the plate. The jet part at the lower end of the rod body can be used to blow away the debris in the groove of the plate, and the debris in the groove can be blown up. The jet part in the rod body that has not entered the cutting groove can blow up the debris on the surface of the plate. The blown up debris and the debris splashed by the cutting drill bit when cutting are sucked into the negative pressure suction chamber, thereby achieving a more thorough cleaning of the cutting groove and the surface of the plate, and avoiding the situation where debris still remains in the cutting groove and the surface of the plate after being cleaned by the brush.

[0020] (2) This solution is provided with an adjustment component. The extension and retraction of the hydraulic rod can drive the jet part to rotate inside the rod body, thereby adjusting the jet angle of the jet part. In this way, the jet part entering the cutting groove can adjust the jet direction according to the shape and depth of the cutting groove, ensuring that the debris is blown out of the groove and the residue in the groove is effectively removed. The blown debris and the debris splashed during cutting are blown into the negative pressure suction chamber, thereby improving the cleaning efficiency of the debris and allowing the debris to be cleaned and collected more quickly.

[0021] (3) This solution is provided with a chip removal enhancement part. When the motor rotates, it can drive the nozzle to rotate inside the shell. The rotating airflow generated by the rotating nozzle is more impactful than the unidirectional airflow, and can more effectively blow the debris out of the groove. The centrifugal force brought by the rotating motion can assist the airflow to loosen and blow up the heavier debris deposited at the bottom of the cutting groove. The combination of centrifugal force and airflow can more effectively clean the cutting groove. The rotating nozzle can continuously change the direction of the airflow to avoid the redeposition of debris in the cutting groove, ensure thorough cleaning, increase the chance of debris entering the dust collection system, and reduce the residual debris.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 A debris collection device for a CNC cutting machine includes a seat body 1, bristles 2 fixed to the lower end of the seat body 1, an extension end 3 integrally formed at the upper end of the seat body 1, a negative pressure suction chamber 32 opened inside the seat body 1 and the extension end 3, and a negative pressure suction cover 31 integrally formed on one side of the extension end 3 and connected to the negative pressure suction chamber 32.

[0035] The seat body 1 is internally movably connected with a plurality of in-groove chip removing units 4, and the in-groove chip removing units 4 include a rod body 42 movably inserted into the seat body 1, a positioning assembly 41 clamped on the outside of the rod body 42, a spring 43 sleeved on the outside of the rod body 42, a limit plate 44 fixed on the outside of the rod body 42, an air jet part 45 rotatably connected to the inside of the rod body 42, a pipe interface 46 fixed on one side of the air jet part 45, and an air supply pipeline 47 connected to the pipe interface 46, and the air supply pipeline 47 passes through the seat body 1 and extends outward, and the two ends of the spring 43 are respectively connected to the upper end of the limit plate 44 and the lower end of the seat body 1.

[0036] The positioning assembly 41 includes a sleeve 411 movably sleeved on the outside of the rod body 42, a positioning slot 413 provided in the sleeve 411 and the inside of the rod body 42, and an insert plate 412 inserted into the sleeve 411 and the positioning slot 413 in the rod body 42 (because the lengths of different drill bits may be different, in order to ensure that the bottom of the drill bit and the bottom of the rod body 42 are located on the same horizontal plane, the position of the sleeve 411 outside the rod body 42 is adjusted to adjust the length of the rod body 42 extending from the seat body 1; the adjustment method is to pull the insert plate 412 out of the positioning slot 413, and then move the sleeve 411 up and down outside the rod body 42, and then insert the insert plate 412 into the positioning slot 413 after the adjustment is completed).

[0037] It also includes a reset component 10, and the reset component 10 includes three guide columns 103 fixedly connected to the upper end of the seat body 1, a second motor 101 fixedly connected to the lower end of the seat body 1, a screw rod 102 rotatably connected to the inside of the seat body 1, and a movable plate 104 movably sleeved on the outside of the guide columns 103, and the screw rod 102 is screwed in the movable plate 104, the output shaft of the second motor 101 is fixedly connected to one end of the screw rod 102, and the movable plate 104 is located between the sleeve 411 and the seat body 1.

[0038] The seat body 1 is provided with a relief groove 11 for facilitating the passage of the shaft head.

[0039] By adopting the above technical solution, the machine tool shaft head is passed through the avoidance groove 11, the seat body 1 is screwed to the outside of the shell 451 of the machine tool shaft head by bolts, and the interface end of the negative pressure suction cover 31 is connected to the input end of the dust collection device. When the machine tool shaft head descends to cut the plate, the drill bit in the machine tool shaft head extends into the plate and cuts the plate. The lower end of the bristle 2 can contact the upper surface of the plate to avoid flying debris during cutting. At the same time, the negative pressure suction chamber 32 can absorb the flying debris. The bottom of the rod 42 is in the same plane as the bottom of the drill bit, so when the drill bit drills into the plate to make a groove, the bottoms of the multiple rod bodies 42 are in contact with the surface of the plate. At the same time, the rod body 42 moves upward in the seat body 1, the spring 43 is compressed, and the jet part 45 inside the rod body 42 blows up the debris on the surface of the plate, so that the dust collection device can suck away the debris through the negative pressure suction chamber 32. When the machine tool shaft head moves in the X-axis or Y-axis direction, a long cutting groove will be left on the plate. When one of the rod bodies 42 moves to the upper side of the cutting groove, When the machine tool axis head needs to turn an angle (from X-axis movement to Y-axis movement), in order to avoid the rod body 42 located in the original cutting groove from getting stuck, the air jet part 45 can blow up the debris accumulated in the cutting groove after the lower end of the rod body 42 is extended into the cutting groove, so as to achieve a more thorough cleaning of the cutting groove and the surface of the plate, and avoid the situation where debris still remains in the cutting groove and the surface of the plate after being cleaned by the brush; when the machine tool axis head needs to turn an angle (from X-axis movement to Y-axis movement), in order to avoid the rod body 42 located in the original cutting groove from getting stuck, the air jet part 45 can blow up the debris accumulated in the cutting groove after the lower end of the rod body 42 is extended into the cutting groove, and the air jet part 45 can blow up the debris accumulated in the cutting groove, so as to achieve a more thorough cleaning of the cutting groove and the surface of the plate, and avoid the situation where debris still remains in the cutting groove and the surface of the plate after being cleaned by the brush; when the machine tool axis head needs to turn an angle (from X-axis movement to Y-axis movement), in order to avoid the rod body 42 located in the original cutting groove from getting stuck, the air jet part 45 can blow up the debris accumulated in the cutting groove after being brushed by the brush, and avoid the situation where the air jet part 45 can blow up the debris accumulated in the cutting groove The motor 2 101 drives the screw 102 to rotate, driving the movable plate 104 to rise. The rise of the movable plate 104 can drive the positioning assembly 41 and the rod body 42 to rise, so that multiple rod bodies 42 can all rise. This can prevent the rod body 42 from getting stuck in the cutting groove when turning a corner. When the machine tool shaft head moves a certain distance after turning a corner, the motor 2 101 drives the positioning assembly 41 and the rod body 42 to reset. At this time, the lower end of one of the rod bodies 42 will extend into the cutting groove after the corner and blow up the debris in the cutting groove after the corner.

[0040] like Figure 3 , Figure 4 and Figure 7 As shown, an adjustment component 5 for driving the jet part 45 to rotate is provided inside the rod body 42, and the adjustment component 5 includes a hydraulic rod 51 fixedly connected to the inside of the rod body 42, a movable seat 52 slidably connected to the inside of the rod body 42, a tooth plate 53 fixed to the lower end of the movable seat 52, a gear 1 54 rotatably connected to the inside of the rod body 42 and meshing with the tooth plate 53, and a tooth key 55 provided on the outer surface of the jet part 45 and meshing with the gear 1 54. The telescopic end of the hydraulic rod 51 is fixedly connected to the upper end of the movable seat 52.

[0041] A sensor 7 is fixedly connected to the lower end of the sleeve 411 , and the sensor 7 is used to detect whether the sleeve 411 is in contact with the movable plate 104 .

[0042] By adopting the above technical solution, the sensor 7 can detect whether the sleeve 411 is in contact with the movable plate 104. When the drill drills into the plate to make a groove, the bottoms of the multiple rods 42 are in contact with the surface of the plate. At the same time, when the rods 42 move upward in the seat 1, the sleeve 411 is separated from the movable plate 104, and the sensor 7 does not send a signal. Only when the bottom of one of the rods 42 extends into the cutting groove, the sleeve 411 outside the rod 42 is in contact with the movable plate 104. The sensor 7 sends a signal to control the hydraulic rod 51 in the rod 42 to work and contract. The hydraulic rod 51 drives the tooth plate 53 to rise. The rising tooth plate 53 can drive the gear 1 54 to rotate clockwise and the jet part 45 to rotate counterclockwise, thereby adjusting the blowing angle of the jet part 45, so that the jet part 45 is changed from the original The horizontal blowing is changed to an inclined blowing toward the bottom of the seat body 1, so that the jet part 45 can blow the debris blown in the cutting groove and the debris blown up on the surface of the plate into the negative pressure suction chamber 32, thereby improving the cleaning efficiency of the debris, so that the debris can be cleaned and collected more quickly. When the hydraulic rod 51 contracts to a certain stroke and then extends, the jet part 45 changes from inclined to horizontal, thereby adjusting the jet angle of the jet part 45 entering the cutting groove, so that the jet part 45 entering the cutting groove can adjust the jet direction according to the shape and depth of the cutting groove, ensuring that the debris is blown up from the groove, effectively removing the residue in the groove, and blowing the blown up debris and the debris splashed during cutting into the negative pressure suction chamber 32, thereby improving the cleaning efficiency of the debris, so that the debris can be cleaned and collected more quickly.

[0043] like Figure 5 As shown, the jet part 45 includes a shell 451 rotatably connected to the inside of the rod body 42, a hose 452 located inside the shell 451 and connected to the pipeline interface 46, a frame 453 connected to the inside of the shell 451, a jet head 455 rotatably connected to the frame 453, and a rotary joint 454 connected to the input end of the jet head 455, the inner tube of the rotary joint 454 is fixedly connected to the input end of the jet head 455, and the input end of the rotary joint 454 is connected to the other end of the hose 452.

[0044] A chip removal enhancement part 6 is also provided inside the frame body 453, and the chip removal enhancement part 6 includes a motor 1 61 fixedly connected to the inner wall of the frame body 453, a gear 2 62 rotatably connected to the inner wall of the frame body 453, and a gear 3 63 fixedly connected to the outside of the nozzle 455 and meshing with the gear 2 62, and the output shaft of the motor 1 61 is fixedly connected to one side of the gear 2 62.

[0045] By adopting the above technical solution, the operation of motor 1 61 can drive gear 2 62 and gear 3 63 to rotate, thereby driving the nozzle 455 to rotate. The rotation of nozzle 455 can generate a rotating airflow, which has more impact than a unidirectional airflow and can more effectively blow the debris out of the groove. The centrifugal force brought by the rotating motion can assist the airflow to loosen and blow up the heavier debris deposited at the bottom of the cutting groove. The combination of centrifugal force and airflow can more effectively clean the cutting groove. The rotating nozzle can continuously change the direction of the airflow to avoid the redeposition of debris in the cutting groove, thereby ensuring thorough cleaning, increasing the chance of debris entering the dust collection system, and reducing residual debris.

[0046] like Figure 5 and Figure 6 As shown, the outer surface of the nozzle 455 is also fixed with a flange 1 66, and one side of the shell 451 is provided with a movable groove 67 for accommodating the movement of the nozzle 455, and two flanges 2 68 are symmetrically fixed on the inner wall of the movable groove 67, and the upper and lower ends of the frame 453 are fixed with support columns 64, and the other ends of the two support columns 64 are rotatably connected to the inner wall of the shell 451, and two groups of tension springs 65 are symmetrically fixed on both sides of the frame 453, and the other ends of the tension springs 65 are connected to the inner wall of the shell 451.

[0047] By adopting the above technical solution, when the motor 1 61 works to drive the nozzle 455 to rotate, the flange 1 66 on the outer surface of the nozzle 455 also rotates with the nozzle 455. When the flange 1 66 contacts one of the flanges 2 68, the flange 2 68 can push the nozzle 455 and the frame 453 to rotate in the shell 451, so as to adjust the lateral angle of the nozzle 455. The flange 1 66 contacts the two flanges 2 68 in turn, and can push the nozzle 455 and the frame 453 to rotate left and right in the shell 451, so that the dead corners in the cutting groove can be better cleaned and the cleaning effect is improved. When the flange 1 66 is separated from the flange 2 68, the tension spring 65 can pull the frame 453 to reset.

[0048] like Figure 8 and Fig. 9 As shown, an atomizer 9 and a venturi tube 8 are fixedly connected to the upper end of the seat body 1, and the output end of the atomizer 9 is connected to the throat input end of the venturi tube 8 through a pipeline, the diffusion end of the venturi tube 8 is connected to the extension end 3 of the gas pipeline 47, and the input end of the venturi tube 8 is used to connect the air pipe.

[0049] By adopting the above technical solution, the atomizer 9 can atomize the water-based antistatic agent and send it into the venturi tube 8. The atomizer 9 is a device that decomposes the liquid into tiny droplets through different physical mechanisms such as mechanical, ultrasonic, pneumatic or electric heating to form a uniform mist spray. It belongs to mature existing technology and will not be repeated here. The output end of the air compressor is connected to the input end of the venturi tube 8. The compressed gas enters the venturi tube 8 and mixes with the atomized water-based antistatic agent and enters the gas pipeline 47, and then sprays out from the nozzle 455. It can reduce the situation that the static electricity generated during the cutting process may cause the debris to adhere to the guide rod and the nozzle, and improve the cleaning effect. The venturi tube 8 is a device that works on the Bernoulli principle. Its design is based on the phenomenon that the fluid increases in speed and decreases in pressure when passing through a narrow channel. When the compressed gas flows through the narrow part of the venturi tube 8, the flow rate increases, resulting in a decrease in pressure there, thereby generating a negative pressure area at the other interface of the tube, which can inhale and mix the atomized antistatic agent. It belongs to mature existing technology and will not be repeated here.

[0050] Usage: Pass the machine tool shaft head through the avoidance groove 11, screw the seat body 1 to the outside of the shell 451 of the machine tool shaft head through bolts, connect the interface end of the negative pressure suction cover 31 to the input end of the dust collection device, control the machine tool shaft head to descend to cut the plate, the drill bit in the machine tool shaft head extends into the plate and cuts the plate, the lower end of the bristle 2 can contact the upper surface of the plate to avoid flying debris during cutting, the negative pressure suction chamber 32 can absorb the flying debris, the bottoms of the multiple rod bodies 42 are in contact with the surface of the plate, and the jet part 45 inside the rod body 42 blows up the debris on the surface of the plate, so that the dust collection device can pass through the negative pressure suction chamber 3 2 sucks away the debris. When the machine tool axis head moves in the X-axis or Y-axis direction, a long cutting groove will be left on the plate. When one of the rod bodies 42 moves to the top of the cutting groove, the spring 43 pushes the rod body 42 to move downward, so that the rod body 42 extends into the cutting groove of the plate. After the lower end of the rod body 42 extends into the cutting groove, the air jet part 45 can blow up the debris accumulated in the cutting groove, so as to achieve a more thorough cleaning of the plate cutting groove and the plate surface. The sleeve 411 outside the rod body 42 extending into the cutting groove of the plate is in contact with the movable plate 104, so the sensor 7 sends a signal to control the hydraulic rod 51 in the rod body 42 to work and retract. The hydraulic rod 51 drives the tooth plate 53 to rise, and the rising of the tooth plate 53 can drive the gear 1 54 to rotate clockwise and the air jet part 45 to rotate counterclockwise, so as to adjust the blowing angle of the air jet part 45, so that the air jet part 45 changes from the original horizontal blowing to the inclined blowing toward the bottom of the seat body 1, so that the air jet part 45 can blow the debris blown in the cutting groove and the debris blown up on the surface of the plate into the negative pressure suction chamber 32, thereby improving the cleaning efficiency of the debris. The operation of the motor 1 61 can drive the gear 2 62 and the gear 3 63 to rotate, thereby driving the air jet head 455 to rotate. The rotating airflow generated by the rotation of the air jet head 455, when the motor 1 61 drives the air jet head 455 to rotate, When the air head 455 rotates, the flange 1 66 on the outer surface of the nozzle head 455 also rotates with the nozzle head 455. When the flange 1 66 contacts one of the flanges 2 68, the flange 2 68 can push the nozzle head 455 and the frame 453 to rotate in the shell 451, so as to adjust the lateral angle of the nozzle head 455. The flange 1 66 contacts the two flanges 2 68 in turn, and can push the nozzle head 455 and the frame 453 to rotate left and right in the shell 451, so that the dead corners in the cutting groove can be better cleaned and the cleaning effect is improved. When the flange 1 66 is separated from the flange 2 68, the tension spring 65 can pull the frame 453 to reset.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
