Description

Technical Field

[0001] The present invention relates to the technical field of laser cloth cutting, and particularly relates to a high-performance laser cloth cutting system. Background Art

[0002] Laser cloth cutting uses a laser with a high power density as a heat source. Through computer-aided design and computer-aided manufacturing technologies, according to the designed cutting trajectory, the cloth to be processed reaches surface melting, evaporation or decomposition under the irradiation of the laser beam to form a cut. The laser spot of laser cutting is small and the energy density is high, so a good cutting quality can be obtained. Its cutting speed is high, and the cloth can be cut without contacting the cloth, and its cutting surface has no burrs.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0042] See also Figures 1-9 The present embodiment provides a high-performance laser cloth cutting system, including a machine frame 1, on which a crossbeam 11 and a plate conveyor belt 12 are arranged. The machine frame 1 is an existing processing equipment, which is used to support the crossbeam 11 and the plate conveyor belt 12. The crossbeam 11 is driven to move by a driving source on the machine frame 1 to adjust its position on the machine frame 1. The plate conveyor belt 12 is also an existing part, which is driven by a separate driving source. A control seat 13 is arranged on the crossbeam 11, in which a laser component is arranged. The control seat 13 is fixed on the crossbeam 11, and a driving source for driving the laser component to move to cut the cloth is arranged in the control seat 13. When the laser component inside the control seat 13 moves, the control seat 13 no longer moves, and the control seat 13 is driven to move on the crossbeam 11 by an external driving source. The crossbeam 11 supports the control seat 13, and the laser component can be moved to different positions for processing through the movement of the crossbeam 11 and the control seat 13; it also includes The present invention also comprises a pushing mechanism, which is arranged in the control seat 13; a storage assembly, which is arranged on the plate conveyor belt 12; and a blanking assembly, which is arranged on the crossbeam 11; the pushing mechanism is triggered to move during the cutting stroke of the laser assembly, and the cloth after cutting is pushed into the storage assembly to avoid adhesion; the pushing mechanism is synchronously triggered to move during the movement stroke of the laser assembly and the cutting is to be completed, and the cloth just cut is pushed into the storage assembly, thereby increasing the distance between the cloth after cutting and the original cloth, and avoiding the possibility of easy adhesion between the two at the cutting point; for some cloths with harder materials, when the pushing mechanism pushes it into the storage assembly, it will cause its edge to warp up, avoiding adhesion with the plate conveyor belt 12; the plate conveyor belt 12 drives the cloth in the storage assembly to move, and drives the cloth to separate from the storage assembly through the blanking assembly to achieve separation; the original cloth and the cloth after cutting can be fully separated by the movement of the plate conveyor belt 12 in coordination with the blanking assembly, so as to achieve separate collection and facilitate subsequent operations.

[0043] In an embodiment further provided by the present invention, the laser assembly includes a laser head 21 disposed in the control seat 13, and a trigger tube 22 is fixedly connected to the laser head 21; the trigger tube 22 is provided with an auxiliary unit for fixing the cloth, and the laser head 21 is a commonly used part of the existing laser cloth cutting system, and is a device for generating lasers. Its specific working principle is an existing well-known technology, and will not be described in detail here. The trigger tube 22 is fixedly wrapped on the outer surface of the laser head 21, and by providing the auxiliary unit, the cloth can be squeezed and fixed when the laser head 21 is cutting, so as to avoid the cloth from moving during the laser cutting process and affecting its overall cutting effect.

[0044] Further, the material pushing mechanism includes a connecting cylinder 31 fixedly connected to the control seat 13. A material pushing rod 32 is connected in the connecting cylinder 31 through a connecting unit. A sleeve 33 is slidably connected to the outside of the connecting cylinder 31. An elastic telescopic rod 34 is fixedly connected between the sleeve 33 and the control seat 13. The elastic force of the elastic telescopic rod 34 drives the sleeve 33 away from the control seat 13. The material pushing rod 32 slides vertically in the sleeve 33. The bottom end of the material pushing rod 32 can be set in a spherical shape and its smoothness needs to be maintained. The smooth contact surface can ensure the smoothness during material pushing.

[0045] Furthermore, the connecting unit includes a rotating bar 41 rotatably connected in the connecting cylinder 31. A first linkage bar 42 and a second linkage bar 43 are respectively rotatably connected to both sides of the rotating bar 41. The first linkage bar 42 is rotatably connected to the top end of the material pushing rod 32. A fixed bar 44 is rotatably connected to the second linkage bar 43. The fixed bar 44 is fixedly connected to the sleeve 33. A groove is formed on the connecting cylinder 31. The rotating bar 41 is installed in the communicating groove. The first linkage bar 42 and the second linkage bar 43 are symmetrically arranged at both ends of the rotating bar 41. The fixed bar 44 slides vertically in the groove inside the connecting cylinder 31.

[0046] In the embodiment further provided by the present invention, a first contact block 51 is fixedly connected to the outside of the sleeve 33. A second contact block 52 is fixedly connected to the trigger cylinder 22. During the movement stroke of the second trigger block, it contacts the first contact block 51. The side of the first trigger block along the reverse direction of the movement direction of the second trigger block is set in an inclined shape. The side of the second trigger block along the movement direction is set in an inclined shape. So that after the second trigger block moves one circle, its inclined side contacts the inclined surface of the first trigger block. When the second trigger block moves to the first trigger block, since the first contact block 51 is fixed to the sleeve 33 and the sleeve 33 is elastically connected to the control seat 13, the second trigger block will push up the first contact block 51. The sleeve 33 is driven to move up through the first trigger block. The sleeve 33 moves up and drives the fixed bar 44 connected thereto to move up synchronously. The fixed bar 44 moves up and pulls the rotating plate to rotate through the second linkage bar 43. The rotating plate rotates and drives the material pushing rod 32 to move towards each other synchronously through the first linkage bar 42, and pushes the cut fabric into the storage component, realizing the separation of the cut fabric.

[0047] In the embodiment provided by the present invention, the storage component includes a plurality of ventilation holes 61 and a plurality of storage slots 62 formed in the plate conveyor belt 12. Each storage slot 62 communicates with the corresponding ventilation hole 61. The storage slots 62 are arranged directly below the fabric to be slit, which is convenient for the cut fabric to be inserted into the storage slots 62 for storage after cutting, avoiding the adhesion with the original fabric on the same plane.

[0048] In the embodiment provided by the present invention, the unloading component includes an air outlet pipe 7 slidably connected to the machine frame 1, and the air outlet pipe 7 is connected to the purifier on the beam 11. The purifier is an existing equipment, which is used to purify the gas during laser cutting to avoid gas pollution, and the gas purified by the purifier is discharged through the air outlet pipe 7. The air outlet pipe 7 moves with the movement of the beam 11, and is connected with the ventilation holes 61 on the plate conveyor belt 12 in turn. The inside of the device is inflated to blow out the cloth stuck in the storage trough, thereby realizing the unloading function.

[0049] In the solution further provided by the present invention, the auxiliary unit includes a plurality of movable cylinders 81 slidably connected to the trigger cylinder 22, and a ball 82 is rotatably connected to the movable cylinder 81; a support rod 83 is fixedly connected to the top of each movable cylinder 81, and a plurality of support rods 83 are fixedly connected to the same rectangular frame 84 at the top ends, and an abutment spring 85 is fixedly connected between the rectangular frame 84 and the trigger cylinder 22, and the elastic force of the abutment spring 85 drives the rectangular frame 84 away from the trigger cylinder 22, and the rectangular frame 84 is slidably connected to the outer surface of the laser head 21, and the plurality of support rods 83 are fixed to the same rectangular frame 84, so that the plurality of ball 82 arranged on the periphery of the laser head 21 can be kept on the same plane, and the ball 82 can roll on the cloth to squeeze and fix the cloth, and the rectangular frame 84 is connected by the abutment spring 85, and has a certain adjustable distance.

[0050] In a solution further provided by the present invention, a plurality of movable cylinders 81 are distributed in a rectangular array. The movable cylinders 81 are distributed in a rectangular array, so that when the laser head 21 moves in different directions, the cloth to be cut can be squeezed and fixed.

[0051] In the solution further provided by the present invention, a cloth conveyor belt 9 is also provided on the machine frame 1, and the cloth conveyor belt 9 is located below the plate conveyor belt 12. The cloth conveyor belt 9 and the plate conveyor belt 12 are connected to the same external driving source, and the two move synchronously in opposite directions. The cloth conveyor belt 9 is used to receive the cloth falling from the plate conveyor belt 12 to achieve separation between the cloths, and the cloth conveyor belt 9 is also an existing traditional conveyor belt, and its specific movement mode is the existing technology, which will not be described in detail here.

[0052] Working principle: When working, the fabric to be slit is laid neatly on the plate conveyor belt 12. The driving source on the machine frame 1 is started to drive the cross beam 11 to move. While the cross beam 11 is moving, the driving source that drives the control seat 13 to move is synchronously controlled to work, so as to adjust the position of the control seat 13 on the cross beam 11. Until it is adjusted to the appropriate position, the driving source stops working and maintains the state before power-off. At this time, the driving source in the control seat 13 is started to control the laser head 21 to move along the set track to slit the fabric on the plate conveyor belt 12. After slitting, the laser head 21 will move to the initial position to complete the full cutting operation of the fabric. When it is about to move to the initial position, the second trigger block on the trigger cylinder 22 of the laser head 21 will contact the first trigger block on the sleeve 33 and push the first trigger block upward. While the first trigger block is being squeezed upward by the second trigger block, it will drive the sleeve 33 to move synchronously. The upward movement of the sleeve 33 drives the second linkage bar 43 to move through the fixed bar 44 fixed inside it. The movement of the second linkage bar 43 pulls the rotating plate to rotate. After the rotating plate rotates, it will push the pushing rod 32 downward through the first linkage bar 42. The downward movement of the pushing rod 32 pushes the slit fabric into the storage groove 62 on the plate conveyor belt 12, so that the slit fabric is completely separated from the original fabric and there will be no adhesion situation;

[0053] When the fabric on the plate conveyor belt 12 is cut, the driving source that drives the plate conveyor belt 12 to work is started so that the plate conveyor belt 12 and the cloth conveyor belt 9 work synchronously. The plate conveyor belt 12 works to convey the fabric in the storage groove 62 away. When the plate conveyor belt 12 conveys the fabric to one end, some of the fabric may fall on the cloth conveyor belt 9 and be conveyed away by the cloth conveyor belt 9, while the fabric that does not fall continues to be stuck in the plate conveyor belt 12. When the laser head 21 repeats the moving stroke again, it drives the air outlet pipe 7 to move to the position at the bottom of the plate conveyor belt 12 and is sequentially connected to the air outlet openings at the bottom part of the plate conveyor belt 12. The gas flowing inside the air outlet pipe 7 enters the ventilation holes 61 and blows the fabric blocking the storage groove of the ventilation holes 61 so that the fabric can be squeezed out.

[0054] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
