Abstract
Description
Technical Field
[0001] This invention relates to the field of warp-knitted fabric processing technology, specifically to a warp-knitted fabric processing device. Background Technology
[0002] Warp-knitted fabrics are widely used in clothing, home textiles, and industrial textiles due to their good elasticity, high strength, and excellent breathability. Laser cutting technology, with its advantages of non-contact processing, high cutting precision, and no mechanical wear, has gradually replaced traditional mechanical cutting methods in the processing of warp-knitted fabrics.
[0003] When cutting warp-knitted fabrics, the high temperature generated by the laser cutting machine can easily cause the edges of the warp-knitted fabric to melt and stick together, forming rough edges. At the same time, the high temperature burning of the fabric will produce black ash. This type of ash particles are very fine and easily adhere to the surface of the warp-knitted fabric, making them difficult to clean. Moreover, the warp-knitted fabrics are usually directly packaged and collected after cutting without undergoing an ash cleaning process, which makes the surface of the finished product easily contaminated with black ash, seriously affecting the appearance quality and cleanliness of the product, and even causing the finished product to be scrapped.
[0004] A search revealed Chinese patent CN120421777B, which discloses a cutting process and equipment for warp-knitted mesh fabric used in automobile seats. This patent relates to the field of laser cutting technology and includes a frame, a laser cutting system, a waste material conveying system, and a finished fabric conveying system. The finished fabric conveying system includes a finished material gripping machine, a gripping lifting device, a gripping device, a dust collection device, a negative pressure feeding pipe, and a rotating device. The dust collection device is installed on the finished material gripping machine, and the negative pressure feeding pipe is connected to the dust collection device. The gripping lifting device is also installed on the finished material gripping machine. The rotating device is installed at the output end of the gripping lifting device, and the gripping device is installed at the bottom of the rotating device. The gripping device is slidably installed inside the dust collection device. The gripping device rises and falls along the dust collection device under the traction of the gripping lifting device, and the rotating device drives the gripping device to rotate. The dust collection device is a downward-opening trumpet shape and is equipped with a vibration device to eliminate black ash generated during the cutting process and prevent contamination.
[0005] In the aforementioned application, the warp-knitted mesh to be cut needs to be manually placed on the scrap material conveying mesh beforehand. Subsequently, the scrap material conveying motor drives the conveying roller to rotate, automatically conveying the mesh to the laser cutting station, completing the initial material loading process of "manual placement + automated conveying". However, the manual placement process not only reduces efficiency but also makes it difficult to ensure the flatness and positioning accuracy of the mesh, thus affecting the dimensional accuracy of the subsequent cutting.

[0017] This invention provides a warp-knitted fabric processing device. It has the following beneficial effects:
[0018] 1. During cutting, the nitrogen nozzle of this invention sprays nitrogen gas, which can disperse the molten material and isolate oxygen to reduce fiber oxidation and carbonization, and avoid or reduce black edges on warp-knitted fabrics; at the same time, the negative pressure inside the rotating cylinder is used to form a negative pressure in the collection chamber through the suction pipe and connecting pipe to adsorb and collect the debris and black ash generated during cutting, so as to avoid impurities adhering to or clogging the equipment and ensure the appearance quality and cleanliness of the product.
[0019] 2. This invention achieves automatic conveying of warp-knitted fabrics through the cooperation of a rotating cylinder and a clamping component, which reduces friction compared to planar drag conveying; the adsorption holes on the surface of the rotating cylinder adsorb the warp-knitted fabrics under negative pressure, making them stably adhere to the cylinder surface, effectively improving the flatness and positioning accuracy of the warp-knitted fabrics, and ensuring accurate subsequent cutting dimensions.
[0020] 3. During the cutting process, the clamping system of this invention uses elastic elements to press down on the warp-knitted fabric to increase the tension. The mounting frame presses down to fix the rotating cylinder, and the first and second extrusion plates cooperate to clamp the clamping roller and fix the warp-knitted fabric to prevent the equipment from rotating or the material from shifting during cutting. The collection chamber can be moved by rotating the bracket and driving the electric slide table to realize the transverse and side cutting of the warp-knitted fabric, and can process square and various other shaped products.
[0021] 4. After the cutting is completed, the electric push cylinder retracts three times to loosen the extruded part from the warp-knitted fabric. The spacer ring continuously blocks the adsorption holes, and the formed product and waste automatically fall off due to the loss of negative pressure adsorption. The protrusions on the bottom wall of the frame can make the formed warp-knitted fabric and waste fall to different positions respectively, realizing automated feeding and waste separation, and improving processing efficiency.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. 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.
[0037] Please see the appendix Figure 1 -Appendix Figure 5This invention provides a warp-knitted fabric processing device, including a frame 1, a material conveying system 2, a material cutting system 3, and a pressing system 5. The material conveying system 2 cooperates with the material cutting system 3 to convey warp-knitted fabric. The material cutting system 3 is used to cut the warp-knitted fabric, and the pressing system 5 is used to press the warp-knitted fabric. The material conveying system 2 is installed inside the frame 1, the material cutting system 3 is located outside the material conveying system 2, and the pressing system 5 is installed above the material conveying system 2. The material cutting system 3 includes a support 301 that moves along the material conveying system 2. An electric push cylinder 306 is fixed at the center of the support 301, and a pressing element 302 is fixed at the driving end of the electric push cylinder 306. Guide rods are fixed on both sides of component 302, and the guide rods pass through bracket 301. A sliding groove 3 is opened inside the clamping component 302. An electric sliding table 303 is fixed inside the sliding groove 3. A collection chamber 304 is fixed on the slider of the electric sliding table 303. A cutting and blowing device is fixed inside the collection chamber 304. An adsorption interface 305 is fixed on the side wall of the collection chamber 304. The cutting and blowing device includes a laser cutting head 316 and a nitrogen nozzle 317. The ammonia nozzle is used to spray ammonia gas during cutting. The laser cutting head 316 is used to cut warp-knitted fabrics. The nitrogen nozzle 317 is connected to a nitrogen supply system. The laser cutting head 316 and its supporting facilities are existing technologies and will not be described in detail here.
[0038] Specifically, one end of the warp-knitted fabric wound into a roll is routed along the surface of the material conveying system 2 and passes through the pressing system 5 and the material cutting system 3. The electric push cylinder 306 extends and pushes the pressing member 302 to press the warp-knitted fabric and fix it in place. At the same time, the debris generated during cutting is intercepted by the collection chamber 304 and collected by the adsorption interface 305. The electric slide table 303 drives the cutting and blowing device to move laterally to perform laser cutting on the warp-knitted fabric. Nitrogen gas is sprayed out during cutting to disperse the molten material, prevent it from sticking to the cut, isolate oxygen, and reduce fiber oxidation and carbonization, thereby avoiding or reducing black edges on the warp-knitted fabric and improving the processing quality of the warp-knitted fabric.
[0039] Please see the appendix Figure 3 - Appendix Figure 6The material conveying system 2 includes a hollow rotating drum 201. One end of the rotating drum 201 is rotatably connected to the frame 1 via a negative pressure pipe 202. A sealing structure, such as a sealing ring, is provided between the negative pressure pipe 202 and the rotating drum 201 for sealing. The negative pressure pipe 202 is connected to a filter and a negative pressure device in sequence. The negative pressure device generates negative pressure, and the filter filters impurities. A motor 4 is fixedly mounted on the side wall of the frame 1. An automatic clutch coupling 8 is fixedly mounted between the drive end of the motor 4 and the other end of the rotating drum 201. Several sets of annularly distributed adsorption holes 203 are opened on the surface of the rotating drum 201. The two ends of the bracket 301 are respectively fixedly mounted on the outer wall of the drive shaft of the motor 4 and rotatably mounted on the outer wall of the negative pressure pipe 202. The clamping part 302 is arc-shaped to fit the rotating drum 201.
[0040] Specifically, initially, the motor 4 drives the support 301 to rotate, causing the cutting and air blowing device to rotate to the horizontal center line behind the conveying direction of the rotating drum 201. Using this as the origin, one end of the warp-knitted fabric is simultaneously placed at this point. Then, the clamping member 302 cooperates with the rotating drum 201 to clamp the warp-knitted fabric end. At this time, the motor 4 rotates through the automatic clutch coupling 8, synchronously driving the clamping member 302 and the rotating drum 201 to rotate, so that the warp-knitted fabric is conveyed and adhered to the surface of the rotating drum 201 until the conveying length is consistent with the cutting length. Then the motor 4 stops running, and the electric pusher cylinder 306 retracts. When the clamping element 302 is opened, the motor 4 rotates in the reverse direction to return to its original position. At this time, the automatic clutch coupling 8 is disconnected, causing the rotating drum 201 to stop rotating. The warp-knitted fabric is then clamped by the clamping element 302 for transverse cutting. The automatic conveying of the warp-knitted fabric can be achieved through the cooperation of the rotating drum 201 and the clamping element 302. At the same time, compared with dragging and conveying on a flat surface, the friction during the conveying of the warp-knitted fabric can be reduced. Negative pressure is generated in the rotating drum 201 through the negative pressure pipe 202, and the warp-knitted fabric is adsorbed through the adsorption hole 203, so that the warp-knitted fabric can be stably attached to the surface of the rotating drum 201, thereby improving the flatness and positioning accuracy of the warp-knitted fabric.
[0041] Please see the appendix Figure 6 -Appendix Figure 7The rotating cylinder 201 has an annular opening on its side wall. A rotating layer 315 is rotatably arranged outside the annular opening. A sealing structure is also provided between the annular opening and the rotating layer 315. An air suction pipe 307 is fixed between the rotating layer 315 and the clamping member 302. The air suction pipe 307 is made of rigid tubing. A connecting pipe 314 is fixed between one end of the air suction pipe 307 installed on the clamping member 302 and the adsorption interface 305. The length of the connecting pipe 314 is longer than that of the clamping member 302. A flexible pipe such as a corrugated pipe can be used. An arc-shaped baffle 308 is fixed at one end of the air suction pipe 307 located inside the rotating cylinder 201. The baffle 308 fits against the inner wall of the rotating cylinder 201. A support ring 309 is fixed at one end of the baffle 308 and is rotatably installed inside the rotating cylinder 201. The support ring 309 is used to support the baffle 308.
[0042] Specifically, the negative pressure inside the rotating cylinder 201 enters the collection chamber 304 through the suction pipe 307 and the connecting pipe 314, thereby adsorbing and fixing the warp-knitted fabric while adsorbing and collecting cutting impurities. The impurities are collected through a filter. When the support 301 rotates, the suction pipe 307 drives the rotating layer 315 and the baffle 308 to rotate synchronously, so that the baffle 308 always corresponds to the pressing part 302. This is used to block the adsorption hole 203 corresponding to the collection chamber 304 during cutting, so as to prevent debris from being sucked into the adsorption hole 203 and causing blockage.
[0043] Please see the appendix Figure 7 The suction pipe 307 includes an outer cylinder 3071 and an inner cylinder 3072 that are slidably connected. A sealing structure is also provided at the intersection of the outer cylinder 3071 and the inner cylinder 3072. An annular body 3073 is fixed inside the outer cylinder 3071. A baffle plate 3074 is provided on the side of the annular body 3073 away from the inner cylinder 3072. The diameter of the baffle plate 308 is smaller than the outer diameter of the annular body 3073 and larger than the inner diameter of the annular body 3073. A connecting rod 3075 that penetrates the annular body 3073 is fixed between the baffle plate 3074 and the inner cylinder 3072.
[0044] Specifically, when the electric push cylinder 306 retracts to its minimum amplitude, the clamping member 302 drives the inner cylinder 3072 to slide outward, and the connecting rod 3075 drives the baffle plate 3074 to block the ring body 3073, thereby preventing the suction pipe 307 from being blocked and avoiding the generation of negative pressure in the collection chamber 304 before and after cutting. On the one hand, this makes the adsorption effect and strength at the adsorption hole 203 better, and on the other hand, it prevents the generation of negative pressure in the collection chamber 304 from adsorbing the warp-knitted fabric and causing it to bulge locally. During cutting, the clamping member 302 drives the inner cylinder 3072 to slide into the outer cylinder 3071, causing the baffle plate 3074 to disengage from the ring body 3073, thereby opening the suction pipe 307 and creating negative pressure in the collection chamber 304 to adsorb the warp-knitted fabric.
[0045] Please see the appendix Figure 8 - Appendix Figure 9The pressing system 5 includes an electric push cylinder 501 fixed at the center of the top of the frame 1. The drive end of the electric push cylinder 501 is fixed with a mounting frame 502. The mounting frame 502 has a sliding groove on each side and a sliding seat 503 is slidably connected thereto. A pressing roller 504 is rotatably arranged between the two sliding seats 503. An elastic element 505 is fixed between the sliding seat 503 and the sliding groove.
[0046] Specifically, the pressure roller 504 is raised by the electric push cylinder 2 501 so that the warp-knitted fabric passes between the pressure roller 504 and the rotating cylinder 201. Then, the pressure roller 504 is lowered so that the warp-knitted fabric is elastically pressed down by the elastic force of the elastic element 1 505, thereby increasing the tension of the warp-knitted fabric and making it fit better on the rotating cylinder 201.
[0047] Please see the appendix Figure 9 The sliding groove is fixedly provided with a stop block 506. The two sides of the sliding seat 503 are respectively provided with a second sliding groove and a locking block 507 is slidably connected. An elastic element 508 is fixed between the locking block 507 and the second sliding groove. The two sides of the mounting frame 502 are respectively slidably connected with a first extrusion plate 509, and the two sides of the mounting frame 502 are respectively slidably connected with a second trapezoidal extrusion plate 510. The automatic clutch coupling 8 is an electrically controlled or hydraulically driven type.
[0048] Specifically, after the clamping member 302 and the rotating cylinder 201 work together to deliver the front end of the warp-knitted fabric into position, the electric push cylinder 501 extends, causing the mounting frame 502 to press down on the rotating cylinder 201 to fix it in place, preventing the rotating cylinder 201 from rotating during cutting. Simultaneously, when the mounting frame 502 abuts against the rotating cylinder 201, the clamping roller 504 slides upward under the obstruction of the rotating cylinder 201 and tightly abuts against the stop block 506. Meanwhile, the extrusion plate 510 slides upward against the rotating cylinder 201, causing the extrusion plate 509 to move from an angled position at its top to its vertical side. This allows the extrusion plate 510 to laterally push the extrusion plate 509 to clamp and fix the clamping roller 504, preventing its deflection and simultaneously fixing the warp-knitted fabric to prevent accidental movement during cutting. The cutting accuracy is affected, and by disconnecting the automatic clutch coupling 8 and the clamping part 302 to return to the origin, the collecting chamber 304 moves to one side of the warp-knitted fabric. It then switches along the rotating cylinder 201 to cut the side of the warp-knitted fabric. Subsequently, the clamping part 302 switches laterally at the return to the origin to cut out square warp-knitted fabric of the required size. When cutting the side, the collecting chamber 304 can also move laterally under the control of the electric slide table 303, so that warp-knitted fabric of various shapes can be cut. When feeding again after cutting, the electric push cylinder 2 501 retracts, so that the mounting frame 502 no longer presses against the rotating cylinder 201. At this time, the extrusion plate 2 510 slides down, so that the extrusion plate 1 509 opens under the action of the elastic part 2 508 and no longer fixes the clamping roller 504.
[0049] Please see the appendix Figure 10 -Appendix Figure 12 On both sides of the rotating cylinder 201, there are several spacer rings 204 that are intersected with the adsorption holes 203, and connecting posts 205 are fixed between the spacer rings 204. A baffle 308 passes through the spacer rings 204, and an elastic element 206 is fixed between the baffle 308 and the spacer rings 204.
[0050] Specifically, the elastic force of the elastic element 206 pulls the spacer ring 204 away from the adsorption hole 203, so that the adsorption hole 203 maintains its suction force.
[0051] Please see the appendix Figure 10 -Appendix Figure 12 The material cutting system 3 also includes a U-shaped frame 310 rotatably mounted on the inner wall of the frame 1. A drive device 6 for driving the U-shaped frame 310 to rotate is mounted on the surface of the frame 1. An electric push cylinder 311 is fixed at the center of the U-shaped frame 310. The drive shaft of the electric push cylinder 311 passes through the rotating cylinder 201 and a T-shaped extrusion member 312 is fixed on the outer wall. The extrusion member 312 is slidably connected to the U-shaped frame 310. A frustum-shaped push head 313 is fixed at the drive end of the electric push cylinder 311. A conical ring 207 is fixed at one end of the spacer ring 204. The drive device 6 includes a motor 42 fixed on the frame 1. A gear 1 is fixed at the drive end of the motor 42, and a gear 2 that meshes with the gear 1 is fixed at one end of the U-shaped frame 310. The motor 42 drives the gear 1 and gear 2 to rotate, thereby transmitting the rotation to the U-shaped frame 310.
[0052] Specifically, after the warp-knitted fabric is conveyed to its position and the clamping component 302 is restored, the driving device 6 drives the U-shaped frame 310 to rotate downwards, causing the end of the extrusion component 312 facing the rotating cylinder 201 to rotate to the front end of the warp-knitted fabric. The electric pusher cylinder 311 extends, causing the extrusion component 312 to press against the rotating cylinder 201 and fix the warp-knitted fabric. At the same time, the extension of the electric pusher cylinder 311 drives the pusher head 313 to move towards the conical ring 207, pushing the conical ring 207 away from the center point of the rotating cylinder 201, until the partition moves to the adsorption hole 203 under the action of the conical ring 207. By blocking the adsorption hole 203, the negative pressure suction is concentrated at the collection chamber 304, improving the collection effect of impurities. After cutting, the electric push cylinder 311 retracts a short distance, so that the extrusion part 312 no longer presses the warp-knitted fabric and the spacer ring 204 continues to block the adsorption hole 203. The formed warp-knitted fabric and the waste on both sides are not affected by the suction of the adsorption hole 203 and fall off automatically, realizing automatic feeding. By fixing a protrusion at the center of the bottom wall of the frame 1, the formed warp-knitted fabric falls on the protrusion, while the waste falls on the bottom wall of the frame 1, realizing the separation of waste and warp-knitted fabric.
[0053] Please see the appendix Figure 10 -Appendix Figure 13The rotating cylinder 201 includes left and right cylinders 2011. A notch is provided on the opposite side of the two cylinders 2011, and an outer ring 2012 is rotatably arranged inside the notch. A sealing structure is also provided between the outer ring 2012 and the cylinder 2011. An inner ring 2017 is fixed on one side of the two cylinders 2011 at the notch. Several U-shaped fasteners 2013 are fixed at both ends of the two inner rings 2017. On the opposite side of the two fasteners 2013, an I-shaped plug 2014 and an I-shaped insert 2015 made of ferromagnetic material are slidably arranged. Magnetic rings that attract each other are fixed at the opposite ends of the plug 2014 and the insert 2015 so that they can be inserted. The outer diameter of the outer ring 2012 is the same as the outer diameter of the cylinder 2011 and is concentrically arranged.
[0054] Specifically, the automatic clutch coupling 8 drives one of the connected cylinders 2011 to rotate, while the other cylinder 2011 is driven by the plug 2014 and the insert 2015. An outer ring 2012 is set to cooperate with the cylinder 2011 to support the warp-knitted fabric. The outer ring 2012 rotates with the drive device 6 under the limiting action of the electric push cylinder 311, so that the drive end of the electric push cylinder can be inserted into the rotating cylinder 201 without causing motion interference.
[0055] Please see the appendix Figure 10 - Appendix Figure 13 Magnetic plates 2016 are fixed on both sides of the drive shaft of the electric push cylinder 311. The magnetic plates 2016 have a greater attraction force on the plug 2014 and the insert 2015 than the magnetic attraction force between them. The rotating cylinder 201 is made of non-magnetic adsorption material.
[0056] Specifically, when the plug 2014 and the socket 2015 are about to rotate to the electric push cylinder 311, the magnetic plate 2016 rotates into the fixing member 2013 before the electric push cylinder 311. Through the magnetic attraction of the magnetic plate 2016 on the plug 2014 and the socket 2015, the plug 2014 and the socket 2015 slide into the fixing member 2013 respectively, thereby opening the plug 2014 and the socket 2015 and avoiding motion interference between the plug 2014 and the socket 2015 and the electric push cylinder 311. At the same time, the transmission is carried out through the insertion of the other plugs 2014 and the socket 2015.
[0057] Workflow:
[0058] S1. Feeding and positioning: One end of the warp-knitted fabric passes through the pressing system 5 and the material cutting system 3. The motor 4 drives the bracket 301 to rotate to the origin. The pressing part 302 cooperates with the rotating cylinder 201 to press the material end.
[0059] S2. Automatic conveying: Motor 4 drives the rotating drum 201 to rotate, and the negative pressure pipe 202 causes the adsorption hole 203 to adsorb the material. After the material is conveyed to the set length while adhering to the drum surface, motor 4 stops.
[0060] S3. Pressing and fixing: Electric push cylinder 2 501 drives mounting bracket 502 to press down, pressing roller 504 elastically presses the material, and extrusion plate 1 509 cooperates with 2 to fix it and prevent displacement.
[0061] S4. Cutting and cleaning: The laser cutting head 316 cuts, the nitrogen nozzle 317 sprays air to prevent black edges, and the suction pipe 307 and the connecting pipe 314 form a negative pressure to adsorb and collect debris and ash.
[0062] S5. Material Discharge and Separation: After cutting, the electric pusher cylinder 311 retracts slightly, the spacer ring 204 blocks the adsorption hole 203, and the material and waste automatically fall and separate.
[0063] S6. Reset Cycle: Each component is reset, and the above steps are repeated for continuous processing.
[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
