Description

Technical Field

[0001] This invention relates to the field of garment processing technology, specifically to a cuff curve cutting machine. Background Technology

[0002] In the garment manufacturing industry, curved fabric pieces such as shirt cuffs are key components affecting garment quality. These pieces have fixed shapes and are produced in large batches, demanding extremely high cutting precision and production efficiency. Traditional curved fabric production often relies on manual marking and cutting, with quality depending on operator skill, making it difficult to guarantee dimensional consistency and failing to meet the demands of modern standardized production. To improve efficiency, the industry commonly uses CNC cutting machines for multi-layer cutting. A CNC cutting machine consists of a vacuum adsorption table, a multi-axis CNC motion system, and a vibrating cutter head. During operation, dozens of layers of fabric are laid flat on the table, covered with a sealing film, and then a high-power vacuum pump is activated. Atmospheric pressure compresses the stacked fabric into a dense block, which is then driven by a servo system to perform high-frequency sawing along a preset CNC path, achieving multi-layer forming in one operation. However, such equipment has a complex structure and requires a high-power vacuum system. Traditional high-precision multi-axis CNC devices are expensive, energy-intensive, and require a large footprint. When used only for cutting single shapes like cuff curves, they are clearly overkill. In recent years, continuous single-layer laser cutting solutions have been gradually applied to the textile industry. These solutions use laser cutting heads for non-contact thermal cutting. Compared to multi-layer vibrating knife cutting beds, laser cutting solutions do not require vacuum adsorption or high-power servo drives, greatly simplifying the structure. However, problems still exist in practical applications: after laser cutting, the cut pieces often form mechanical locks with the original fabric due to electrostatic adsorption and fiber fuzz hooking, making it impossible to reliably separate and drop the material automatically. Manual intervention is required to remove them, which seriously restricts the unmanned operation of continuous production lines. At the same time, the cutting heads of existing laser cutting equipment are mostly fixed, making it difficult to quickly increase or decrease the number or adjust the lateral position according to the fabric width and layout requirements. Changing styles and adjusting the machine is time-consuming and lacks flexibility. Summary of the Invention

[0003] This invention provides a cuff arc cutting machine that can achieve reliable separation by first micro-vibration peeling and then strong knocking, thereby avoiding the retention of cut pieces and original fabric due to mechanical locking.

With the help of the limiting frame and guide roller, the fabric is lifted away from the suspended space gap formed by the conveyor belt, so that the cut piece can be reliably separated from the original fabric. This overcomes the mechanical locking between the cut piece and the original fabric caused by electrostatic adsorption and fiber fuzz hooking, so that the cut piece is separated smoothly and without obstruction.

[0014] 2. The cuff arc cutting machine disclosed in this invention can simultaneously press or release the entire row of locking frames by driving the extrusion plate with a single locking screw, thereby achieving one-time synchronous fixing and release of multiple laser cutting heads. It can quickly increase or decrease the number of cutting heads and adjust their lateral position. At the same time, the separating piece can be independently adjusted laterally to facilitate one-to-one correspondence with each laser cutting head. During the cuff arc cutting process, the efficiency of changing styles and adjusting the machine is significantly improved. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-7 This embodiment provides a cuff curve cutting machine, including a cutting machine base 1, a separation mechanism and a disassembly mechanism.

[0019] A movable cutting frame 2 is provided on the rear side of the upper end of the cutting machine base 1. A mounting frame 3 is provided in the middle of the upper end of the cutting machine base 1. The mounting frame 3 is fixedly connected to the upper end of the cutting machine base 1 by bolts. The mounting frame 3 has a gate-shaped frame structure. A sliding frame 4 is slidably connected inside the mounting frame 3. The sliding frame 4 also has a gate-shaped frame structure. Sliding columns are provided on the left and right sides of the sliding frame 4. Guide sliders are provided on the left and right sides inside the mounting frame 3. The inner wall of the guide slider is slidably connected to the outer surface of the vertically adjacent sliding column. A two-axis module 9 is provided on the rear side of the upper end of the cutting machine base 1. The upper end of the slider of the two-axis module 9 is fixedly connected to the middle of the lower end of the cutting frame 2. The input end of the two-axis module 9 is electrically connected to the output end of the central control unit. The two-axis module 9 consists of an upper X-axis linear module and lower left and right modules. The cutting frame 2 consists of two Y-axis linear modules. The X-axis linear module is arranged along the width of the cutting machine base 1, and the Y-axis linear module is arranged along the length of the cutting machine base 1. Each linear module is composed of a ball screw pair and a linear guide pair. The linear guide pair adopts a rolling linear guide. Each axis is driven by a servo motor. The encoder feedback signal of the servo motor is connected to the central control unit to form a position closed-loop control. The X-axis and Y-axis servo motors of the two-axis module 9 are controlled by the central control unit through a pulse output module. During cutting, the two axes work together to realize the trajectory interpolation of the cuff arc. Limit switches and origin switches can be added at both ends of the X-axis and Y-axis of the two-axis module 9 to limit the range of motion and realize the zero-return operation, providing a stable driving effect for laser cutting. Pressure rollers 8 are provided on both rear sides. The lower ends of the pressure rollers 8 are fixedly connected to the upper end of the cutting machine base 1. A conveyor belt 10 is provided inside the upper end of the cutting machine base 1. The input end of the conveyor belt 10 is electrically connected to the output end of the central control unit. The lower ends of the outer surfaces of the pressure rollers 8 are in contact with the upper end of the conveyor belt 10. The conveyor belt 10 is an integrated material conveying device, including a conveyor belt body, a drive roller, a driven roller, a tensioning mechanism, and a drive motor. The conveyor belt body is a Teflon-impregnated glass fiber mesh belt, which can withstand high laser temperatures. The drive roller is driven by a three-phase asynchronous geared motor, which is equipped with a worm gear reducer with a reduction ratio of 1:20. The tensioning mechanism is a screw-adjustable type, which achieves the tensioning of the conveyor belt body by adjusting the front and rear positions of the driven roller. The drive motor of the conveyor belt 10 is controlled by the central control unit via a variable... The frequency converter controls the start, stop, and speed adjustment. A rotary encoder can be added to the drive roller shaft end of the conveyor belt 10 to detect the actual running speed and displacement of the conveyor belt 10 and feed the signal back to the central control unit, realizing closed-loop control of the feeding length. Simultaneously, an external feeding device is located at the rear of the equipment. This external feeding device is a feeding roller frame, on which replaceable original fabric rolls are installed. The feeding rollers are air-expanding shafts for quick loading and unloading of fabric rolls. After inflation, the outer diameter of the air-expanding shaft expands, tensioning the inner core of the fabric roll. An external receiving device is located at the front of the equipment. This external receiving device is a receiving roller frame, on which receiving rollers are installed. The receiving rollers are driven by a torque motor to wind up the cut waste fabric with constant tension. The output torque of the torque motor is adjustable to match the winding tension requirements of different fabrics.The feeding system comprises an external feeding device, conveyor belt 10, and external receiving device. This system is coordinated and controlled by a central control unit. The drive motor of the conveyor belt 10 and the torque motor of the external receiving device operate synchronously and intermittently. The fabric tension between the conveyor belt 10 and the external receiving device is adjusted by the output torque of the torque motor. Tension sensors can be added to both the front and rear sides of the equipment to detect fabric tension in real time and feed signals back to the central control unit. The central control unit adjusts the output torque of the receiving torque motor based on the tension signals, achieving closed-loop control of the fabric tension. This prevents the fabric from being too loose and wrinkled or too tight and taut, providing a pressing and conveying effect for both the raw fabric and the cut pieces.

[0020] The separation mechanism includes a mounting slide rail 51, a top block 52, a drive wheel, a separation plate, a return spring 56, and a clamping assembly. The mounting slide rail 51 is slidably connected to the lower end of the sliding frame 4. The mounting slide rail 51 has an I-shaped cross-section. Guide slide posts are provided on the left and right sides inside the sliding frame 4. Guide slide holes are opened on the left and right sides inside the mounting slide rail 51. The outer surface of the guide slide post is slidably connected to the inner wall of the vertically adjacent guide slide hole. Clearance openings are provided at the lower left and right ends of the front and rear sides of the mounting slide rail 51. The top block 52 is positioned on the mounting slide rail 51. At the upper center of the sliding frame 4, a rotatable drive wheel is provided inside. The drive wheel is configured to cooperate with the top block 52. The top block 52 and the drive wheel need to be replaced regularly to avoid wear and failure. The drive wheel includes a wheel body 531, knurling 532, and protrusions 533. The wheel body 531 is located at the upper center of the sliding frame 4. The knurling 532 is evenly distributed on the outer surface of the wheel body 531. The protrusions 533 are located at the upper end of the wheel body 531. Both the knurling 532 and the protrusions 533 are configured to cooperate with the top block 52. The distance between the end of the knurling 532 and the center of the wheel body 531 is... The spacing between the pieces is less than the distance between the end of the protrusion 533 and the center of the wheel 531, allowing for quick separation of the cut pieces. Each separating piece is located on the lower end of the outer surface of the mounting slide rail 51. The separating pieces can be added, removed, or removed at the clearance opening. Each separating piece includes an adjusting frame 541, a pressure plate 542, a fixing knob 543, and a positioning hole 544. The adjusting frame 541 is slidably connected to the lower end of the outer surface of the mounting slide rail 51. The adjusting frame 541 has a C-shaped cross-section. The pressure plates 542 are all located on the lower end of the outer surface of the adjusting frame 541. The fixing knobs 543 are all threaded. The positioning holes 544 are evenly distributed in the middle of the front side of the inner side of the mounting slide rail 51. The rear side of the outer surface of the fixing knob 543 is threaded to the inner wall of the longitudinally adjacent positioning holes 544, providing a basis for the disassembly and adjustment of the separation piece. The lower end of the mounting slide rail 51 and the bottom wall of the sliding frame 4 are provided with a return spring 56. The return spring 56 is sleeved on the lower end of the outer surface of the guide slide column. The return spring 56 needs to be replaced regularly to avoid aging and failure. The clamping component is set in the lower end of the inner side of the mounting frame 3.

[0021] The clamping assembly includes a connecting frame 551, a pressure frame 552, a buffer spring 553, a limiting frame 554, and a guide roller 555. The connecting frame 551 is respectively located on the left and right sides of the lower end of the sliding frame 4. The connecting frame 551 is a straight plate-shaped structure. The pressure frames 552 are slidably connected to the lower end of the connecting frame 551. A buffer spring 553 is provided between the bottom wall of the pressure frame 552 and the top wall of the vertically adjacent connecting frame 551. The buffer spring 553 is sleeved on the middle of the outer surface of the pressure frame 552. An adjusting knob 7 is threadedly connected to the upper end of the outer surface of the pressure frame 552. The lower end of the adjusting knob 7 is in contact with the upper end of the vertically adjacent connecting frame 551. The pre-compression of the buffer spring 553 can be adjusted by adjusting the knob 7. The buffer spring 553 can also be replaced periodically by disassembling and assembling the adjusting knob 7. The frames 554 are respectively set at the lower ends of the left and right side walls of the mounting frame 3. The lower ends of the pressing frames 552 are all set to cooperate with the upper ends of the vertically adjacent limiting frames 554. When the equipment is running, the lower ends of the pressing frames 552 can fit against the upper ends of the vertically adjacent limiting frames 554, thereby pressing the fabric. A diaphragm pressure sensor can be added to the lower end of the pressing frame 552. The diaphragm pressure sensor is bidirectionally electrically connected to the central control unit and can monitor the pressing force of the pressing frame 552 in real time. Guide rollers 555 are rotatably connected between the two limiting frames 554. The upper end of the outer surface of the guide rollers 555 is on the same horizontal plane as the upper end of the limiting frames 554. There is a material drop gap in the middle of the limiting frames 554 and the guide rollers 555, which is used for the cut pieces that are knocked off by the separated pieces to pass through and fall onto the surface of the conveyor belt 10, providing a basis for the lifting and pressing of the fabric.

[0022] The separation mechanism also includes a motor 57 and a cylinder 58. The motor 57 is located in the middle of the top wall of the sliding frame 4. The input end of the motor 57 is electrically connected to the output end of the central control unit. The front end of the output shaft of the motor 57 is fixedly connected to the rear end of the wheel 531. The motor 57 is a servo motor equipped with a reducer with a reduction ratio of 1:5. The cylinder 58 is located in the middle of the upper end of the mounting frame 3. The lower end of the telescopic end of the cylinder 58 is fixedly connected to the middle of the upper end of the sliding frame 4. The sliding frame 4 can slide stably up and down inside the mounting frame 3, so that when the cylinder 58 is working, the axial load is the main load, and the radial load becomes very small, making it less prone to damage. The cylinder 58 is a double-acting cylinder. The air pipe is connected to an external air compressor. Both the air inlet and outlet of cylinder 58 are equipped with throttle valves to adjust the piston movement speed and prevent the sliding frame 4 from rising and falling too quickly and causing impact. The actions of motor 57 and cylinder 58 are coordinated and controlled by the central control unit. Cylinder 58 first presses down to the position and then triggers the limit switch. The limit switch feeds the signal back to the central control unit, which then issues a command to start motor 57 to drive the drive wheel to rotate. After completing one separation cycle, motor 57 stops and cylinder 58 retracts. Magnetic switches can be added at the upper and lower stroke ends of cylinder 58 to detect the position of the cylinder piston and feed back the position signal to the central control unit, providing a basis for the separation of the raw fabric and the cut piece.

[0023] The assembly / disassembly mechanism includes a mounting slot 61, fixing blocks 62, and a laser cutting head 63. The mounting slot 61 is located inside the front side of the cutting frame 2. The mounting slot 61 is a rectangular cross-section slot that runs through the length of the crossbeam of the cutting frame 2, with open ends for easy removal, placement, addition, and removal of the equipment. The fixing blocks 62 are all slidably connected inside the mounting slot 61. The laser cutting heads 63 are all located at the front end of the fixing blocks 62. The input end of the laser cutting head 63 is electrically connected to the output end of the central control unit. The laser cutting head 63 is a combination of a CO2 radio frequency laser and a two-dimensional scanning galvanometer. The laser cutting head 63 is modular, with its light outlet facing the downward cutting area. It integrates a galvanometer scanning system to deflect the laser beam at high speed along a preset cuff arc path. A coaxial annular fume hood can be integrated into the lower part of the laser cutting head 63. The fume hood is connected to an external smoke exhaust system via a smoke pipe. A compressed air knife can be added below the fume hood, forming a downward air curtain to isolate cutting smoke and dust, protect the galvanometer lens, and provide optimal laser cutting results. The assembly / disassembly mechanism also includes a locking frame 64, a second return spring 65, a pressing plate 66, and a locking screw 67. All locking frames 64 are slidably connected to the inner middle of the fixing block 62. The upper and lower ends of the front sidewall of the mounting groove 61 have evenly distributed locking holes. The front end of the outer surface of each locking frame 64 is inserted into the inner wall of the longitudinally adjacent locking hole. A second return spring 65 is provided between the middle of the front sidewall of the fixing block 62 and the middle of the front end of the locking frame 64. The second return spring 65 is sleeved on the middle of the outer surface of the locking frame 64. The second return spring 65 needs to be replaced regularly to avoid aging and failure. The extrusion plate 66 is slidably connected to the middle of the rear side of the inner side of the cutting frame 2. The rear ends of all are in contact with the front end of the extrusion plate 66. The locking screw 67 is rotatably connected to the middle of the inner rear side of the cutting frame 2. The outer front side of the locking screw 67 is threadedly connected to the middle of the inner rear side of the extrusion plate 66. A bellows with a sealing flange can be added between the rear end of the extrusion plate 66 and the rear side wall of the cutting frame 2. The bellows is sleeved on the middle of the outer surface of the locking screw 67. The bellows can contract and expand as the extrusion plate 66 moves back and forth, providing protection for the locking screw 67 and providing a basis for the simultaneous locking and release of all the fixing blocks 62.

[0024] The working principle of the cuff curve cutting machine provided by this invention is as follows: When using the cuff curve cutting machine, the external feeding device located at the rear of the equipment releases the original fabric. In conjunction with the intermittent operation of the conveyor belt 10, the fabric is conveyed forward. When the fabric passes under the front and rear pressure rollers 8, it is flattened and adheres to the surface of the conveyor belt 10. Then the fabric continues to move forward, clinging to the upper surface of the limit frame 554 and guide roller 555. It is then retrieved by the external receiving device located at the front of the equipment. The limit frame 554 and guide roller 555 are in a high position, so the fabric is lifted off the surface of the conveyor belt 10 at the limit frame 554 and guide roller 555, creating a gap between the fabric and the surface of the conveyor belt 10. When the equipment is running, the feeding system formed by the external feeding device, the external receiving device, and the conveyor belt 10 operates intermittently. After the fabric reaches the preset position, the feeding system stops operating, completing the feeding and positioning of the fabric.

[0025] When the fabric reaches the preset position, laser cutting begins. The two-axis module 9 drives the cutting frame 2 to move to the cutting start position. The laser cutting head 63 emits a laser, and the two-axis module 9 drives the cutting frame 2 to move along the preset cuff arc path. The laser beam cuts through the fabric along the path, cutting out cuff-shaped pieces on the original fabric. After cutting is completed, the laser is turned off, and the cutting frame 2 is reset. At this time, the edges of some pieces are completely separated from the original fabric, while the edges of some pieces will form a mechanical lock with the original fabric due to electrostatic adsorption and fiber fuzz hooking, making it impossible to reliably separate from the original fabric automatically. After the fabric passes the pressure roller 8 on the front side, it is lifted off the surface of the conveyor belt 10 by the limit frame 554 and the guide roller 555. At this time, the pieces that are completely separated from the original fabric will detach from the original fabric and fall onto the surface of the conveyor belt 10, where they will be conveyed forward by the conveyor belt 10. The pieces that are mechanically locked with the original fabric will move to the limit frame 554 and the guide roller 555 as the original fabric is lifted off.

[0026] When the back part of the original fabric is laser cut, the cut pieces located at the limit frame 554 and guide roller 555 are separated at the same time. The telescopic end of the cylinder 58 extends downward, pushing the sliding frame 4 to move downward along the mounting frame 3. At the same time, it drives the connecting frame 551 and the pressure frame 552 to move downward synchronously. The lower end of the pressure frame 552 presses against the upper end of the limit frame 554, pressing and fixing the edge of the original fabric attached to the guide roller 555 and the limit frame 554. The buffer spring 553 will gradually contract during the downward pressing process to form a buffering effect, thereby preventing the pressure frame 552 from damaging the fabric.

[0027] Then, the motor 57 drives the drive wheel to rotate one revolution, completing one separation cycle. When the drive wheel rotates, the knurling 532 on the outer surface of the wheel body 531 first contacts the top block 52. The distance from the end of the knurling 532 to the center of the wheel body 531 is small, which can push the top block 52 and the mounting slide rail 51 to generate high-frequency small-amplitude reciprocating motion. When the end of the knurling 532 contacts the upper end of the top block 52, the top block 52 and the mounting slide rail 51 move down. When the upper end of the top block 52 is between the two knurling 532, the top block 52 and the mounting slide rail 51 reset, so that the mounting slide rail 51 drives each separation piece to form a rapid micro-vibration effect, breaking the electrostatic adsorption and mechanical locking of carbonized particles between the cut piece and the original fabric. The reset spring 56 can make the mounting slide rail 51 quickly reset after each press.

[0028] After the knurling section 532 rotates, the protrusion 533 contacts the top block 52. The distance from the end of the protrusion 533 to the center of the wheel 531 is greater than the distance from the end of the knurling section 532 to the center. Therefore, the protrusion 533 can push the top block 52 and the mounting slide rail 51 downwards for a greater stroke, so that the pressure plate 542 of the separating piece presses down on the cut piece with a strong force, avoiding the occurrence of incomplete separation. Since there is a gap between the fabric and the conveyor belt 10, and there is a material drop gap in the middle of the limit frame 554 and the guide roller 555, the cut piece will fall off from the original fabric after being patted. It will fall onto the surface of the conveyor belt 10 through the material drop gap and be conveyed forward by the conveyor belt 10. After the drive wheel rotates once, it stops, completing a complete separation cycle of first micro-vibration peeling and then strong patting.

[0029] After the cut pieces are separated, the telescopic end of the cylinder 58 retracts, causing the sliding frame 4 and the pressure frame 552 to rise. The pressure frame 552 releases the fabric, and the feeding system starts operating again, conveying the cut, hollowed-out waste fabric forward to the external receiving device for winding. At the same time, new original fabric enters the cutting area below the cutting frame 2 and enters the next work cycle.

[0030] When the equipment needs to be changed, the number of laser cutting heads 63 needs to be increased or decreased, or the lateral position needs to be adjusted, rotate the locking screw 67. The locking screw 67 drives the extrusion plate 66 to move backward. The return spring 65 pushes the locking frame 64 to move backward. The locking frame 64 slides out of the locking hole, and all the fixing blocks 62 are released simultaneously. The fixing blocks 62 and the front laser cutting heads 63 can be adjusted or removed by sliding them laterally along the mounting groove 61 (the fixing blocks 62 and the front laser cutting heads 63 can be removed from the openings at both ends of the mounting groove 61). After adjustment, reverse the locking screw 67. The extrusion plate 66 moves forward and extrudes all the locking frames 64, so that the front end of the locking frame 64 is inserted into the corresponding locking hole, thereby allowing all the fixing blocks 62 and the laser cutting heads 63 to move backward. 3. Simultaneously, the separation pieces need to be adjusted synchronously. Reverse the fixing knob 543 to separate the fixing knob 543 from the positioning hole 544, and the adjusting frame 541 loses its limiting effect. Move the adjusting frame 541 and the pressure plate 542 laterally until the adjusting frame 541 and the pressure plate 542 move to the appropriate position. Turn the fixing knob 543 forward to make the fixing knob 543 re-enter the positioning hole 544, completing the adjustment of the separation pieces. After the adjustment is completed, the number of separation pieces is the same as the number of laser cutting heads 63, and the separation pieces are longitudinally adjacent to the laser cutting heads 63. The left and right ends of the front and rear sides of the mounting slide rail 51 are provided with clearance openings. The width of the adjusting frame 541 of the separation piece is smaller than the width of the clearance opening, so the separation pieces can be added or removed at the clearance opening.
