Description

Technical Field

[0001] This invention relates to the field of knitting technology, specifically to a single-needle machine and method for knitting mattress textiles. Background Technology

[0002] As an important household item, mattresses require their surface textiles to not only meet basic requirements of aesthetics and comfort, but also to possess good breathability, elasticity, and durability. Traditional mattress textiles are typically produced using ordinary looms or weaving machines, which have significant limitations when processing mattress-specific fabrics. Due to their unique usage environment and functional needs, mattress textiles often require features such as zoned support, high elastic recovery, and breathability and moisture wicking, which places higher demands on weaving equipment.

[0003] Single-needle knitting machines, as precision knitting equipment, are widely used in high-end textile production due to their ability to independently control each needle and knit complex fabric structures. In the mattress manufacturing industry, single-needle knitting machines are mainly used to produce mattress edge fabrics, surface decorative layers, and functional composite fabrics. Traditional single-needle knitting machines typically include core components such as a frame, needle bed, needle system, cam mechanism, yarn feeding device, drafting and take-up mechanism, and basic control system. While these machines perform well when knitting ordinary textiles, they face numerous technical bottlenecks when addressing the specific needs of mattress-specific textiles.

[0004] For example, patent document CN217149523U provides a single-needle machine with a fabric clamping support mechanism, belonging to the field of single-needle machines. It includes a double-beam single-needle machine with the fabric clamping support mechanism. The fabric clamping support mechanism is located within a first frame and below the left and right fabric clamping beams. The fabric clamping support mechanism can move along the machine frame with the first frame and supports the left and right fabric clamping beams along their length. By setting this fabric clamping support mechanism within the first frame of the double-beam single-needle machine, the mechanism can move along the machine frame with the first frame and support the left and right fabric clamping beams along their length, preventing the middle section of the fabric clamping beams from bending downwards and deforming during fabric clamping. This ensures the fabric is clamped securely, thereby improving the sewing quality of the fabric by the double-beam single-needle machine.

[0005] Although existing single-needle sewing machine technology effectively solves the problem of fabric bending and deformation under vertical force by configuring rigid fabric clamping support mechanisms and reinforced fabric clamping beam structures, ensuring the stability of initial clamping, in actual sewing operations, especially when sewing complex curves and oscillating paths, the continuous movement of the machine head generates a continuous and directionally changing traction force on the fabric in the sewing direction. As the sewing path extends, these dynamic traction forces accumulate and form progressive shear stress at the clamping interface, eventually exceeding the static friction limit of the clamping head, resulting in imperceptible micro-displacement between the fabric and the clamping device. Although this micro-slippage phenomenon is not easily detected by the naked eye, it directly leads to quality problems such as sewing trajectory deviation, stitch discontinuity, and three-dimensional structural misalignment, seriously damaging the structural integrity and functionality of mattress textiles. Therefore, this application proposes a single-needle sewing machine and method for weaving mattress textiles. Summary of the Invention

[0012] Preferably, a controller is provided on the top of the pressure head, the controller is used to detect the flow of the medium in the pressure relief tank, a micro air pump is fixedly connected to the top of the pressure head, an air nozzle is rotatably connected to one end of the pressure head, the output end of the micro air pump is connected to the air nozzle through an air supply pipe, and an adjustment handle that is rotatably connected to the air nozzle is rotatably connected to one end of the positioning pressure plate.

[0013] Preferably, a displacement frame is fixedly connected to the bottom of the frame, and sliding shoes adapted to the displacement frame are fixedly connected to both sides of the load rack.

[0014] Preferably, a first guide frame is fixedly connected inside the frame, a main unit is slidably connected to the outer surface of the first guide frame, a cross frame is fixedly connected to the top of the main unit, a second linear module is slidably connected to the outer surface of the cross frame, the second linear module is used to drive the quilting machine head to rise and fall, and a first linear module is fixedly connected to one side of the cross frame to drive the second linear module to move.

[0015] Preferably, the host is internally fixedly connected to a guide frame for sliding connection of the needle bed, and a third linear module for driving the movement of the needle bed is fixedly connected to one side of the guide frame.

[0016] The present invention also provides a single-needle machine and method for knitting mattress textiles, comprising the following steps: S1. Initial positioning and fixation: After the mattress textiles are laid out by adjusting the position of the shelf, the pressure head is driven by the adjustment component to press down for initial fixation. S2. Dynamic tension sensing and main compensation: During sewing, the adjustment component controls the pressure head on the downstream side of the quilting machine head to press down according to the position and direction of the quilting machine head; this pressing action automatically triggers the linkage winding action, causing the corresponding side tightening roller to rotate to tighten the fabric in a centripetal direction. S3, Cascaded Enhanced Anchoring: The downward pressure and airflow drive further trigger the cascaded anchoring action, causing the anchoring component to extend multiple thin pressure rods to form distributed anchor points, thereby enhancing local shear resistance.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. A dual-guide support structure consisting of a frame, a first guide frame, a second guide frame, and the main unit, combined with a three-dimensional motion system formed by a crossbar, a first linear module, and a second linear module, achieves precise positioning and stable movement of the quilting machine head in three-dimensional space, significantly improving the accuracy and consistency of the sewing trajectory. The cooperation between the guide frame and the third linear module ensures that the needle bed moves synchronously with the quilting machine head, maintaining an ideal sewing geometry and effectively solving the problem of stitch deviation during complex pattern weaving. The multi-point fastening system achieves precise regional fixation of the mattress textile through multiple evenly distributed pressure heads on the carrier frame. Combined with the adjustment component consisting of positioning blocks and adjustment cylinders, it can dynamically adjust the pressure distribution of each pressure head according to the real-time position and movement direction of the quilting machine head, forming an adaptive pressure field that counteracts the sewing tension. The intelligent monitoring network composed of a laser positioner and a receiver can accurately capture the movement trend of the quilting machine head, enabling the system to predict and counteract the non-uniform tension generated during sewing, effectively preventing fabric micro-slippage. The tension compensation system, through a mechanical linkage mechanism formed by the tension roller, cam rod, piston rod, hinge seat, and crank, intelligently converts the downward pressure of the press head into the tension force of the fabric, achieving a dynamic balance between pressure and tension. The pneumatic transmission system, consisting of an air cylinder, limit rod, and telescopic tube, allows the vertical displacement of the press head to automatically adjust the rotation angle and direction of the tension roller, ensuring that the fabric maintains optimal tension at different stages of sewing.

[0018] 2. A multi-stage energy dissipation structure, comprising a positioning pressure plate, a telescopic cushion, a pressure relief groove, and a cavity, effectively absorbs and converts the high-frequency vibration energy generated during high-speed sewing at the quilting machine head. When vibration is transmitted to the positioning pressure plate, the gas inside the telescopic cushion is pressurized and flows through the pressure relief groove. The airflow resistance converts the vibration kinetic energy into heat energy, significantly reducing the vibration amplitude. The anchoring assembly, through the flow channel design of the side groove, the confluence cavity, and the back pressure groove, intelligently guides some of the vibration energy to the telescopic pressure bar, driving the common plate to automatically extend multiple thin pressure bars, forming a micro-anchor point array. This achieves an adaptive fixing mechanism where the greater the vibration, the stronger the anchoring. The coordinated design of the side pressure groove and the narrowing hole on the piston rod allows the system to dynamically adjust its damping characteristics according to the sewing conditions, providing strong damping during high-speed sewing and reducing damping during fine work, ensuring optimal sewing results. The controller monitors the system vibration status in real time and intelligently controls the micro air pump to deliver airflow to the air nozzle through the air delivery pipe. It can not only actively suppress vibration, but also automatically adjust the airflow direction to precisely cool the quilting head through the linkage mechanism between the adjustment handle and the positioning pressure plate.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0022] Example 1: Please refer to Figure 1 - Figure 10This invention provides a technical solution: a single-needle machine for knitting mattress textiles, comprising a frame 100 and a quilting head 105 for sewing mattress textiles 101. A first guide frame 103 is fixedly connected inside the frame 100. A main unit 102 is slidably connected to the outer surface of the first guide frame 103. A crossbeam 104 is fixedly connected to the top of the main unit 102. A second linear module 107 is slidably connected to the outer surface of the crossbeam 104. The second linear module 107 is used to drive the quilting head 105 to rise and fall. A first [missing information - likely a device or mechanism] is fixedly connected to one side of the crossbeam 104 for driving the second linear module 107 to move. A straight-line module 106 is provided. Inside the main unit 102, a guide frame 111 is fixedly connected for sliding connection of the needle bed 108. A third straight-line module 110 for driving the movement of the needle bed 108 is fixedly connected to one side of the guide frame 111. A second guide frame 109 is also provided inside the frame 100 for sliding of the main unit 102, which further improves the stability of the movement of the quilting head 105. The first guide frame 103, the first straight-line module 106 and the second straight-line module 107 can realize the three-dimensional movement of the quilting head 105, thereby adapting to different sewing jobs. The needle bed 108 is set to move synchronously with the quilting head 105.

[0023] The multi-point fastening system includes a support frame 200 located below the quilting machine head 105 for supporting the mattress textile 101. Multiple pressure heads 203 are evenly arranged on both sides of the support frame 200. The system also includes an adjustment component for adjusting the height of the pressure heads 203. The adjustment component can adjust the height of each pressure head 203 according to the position of the quilting machine head 105. By setting multiple pressure heads 203, the mattress textile 101 can be supported and fixed. The adjustment component can control the height of each pressure head 203 separately, thereby adjusting the compression and fixing strength of the pressure head 203 on the mattress textile 101, so that it can apply different instantaneous pressures in different working environments.

[0024] The frame 100 is fixedly connected to a displacement frame 201 at its bottom, and the shelves 200 are fixedly connected to two sides with sliding shoes 202 that are compatible with the displacement frame 201. By setting the displacement frame 201 and the sliding shoes 202, the shelves 200 can be moved as a whole, which makes it easier to pick up and put down the mattress textiles 101 and improves convenience.

[0025] The tension compensation system includes a tension roller 300 rotatably connected inside the pressure head 203. Both ends of the tension roller 300 are connected to cam rods 301. The pressure head 203 is equipped with a drive assembly that can drive the cam rods 301 to rotate. The drive assembly adjusts the forward and reverse rotation of the tension roller 300 according to the height of the pressure head 203. By setting the tension roller 300 to abut against the surface of the mattress textile 101, it cooperates with the drive assembly to achieve forward and reverse rotation according to the squeezing intensity of the pressure head 203 on the mattress textile 101, thereby realizing the tensioning and relaxation of the mattress textile 101 fabric.

[0026] Furthermore, the positioning component includes a positioning block 204 fixedly connected to the side of the carrier 200. The top of the positioning block 204 is fixedly connected to an adjustment cylinder 205 connected to the press head 203. The bottom of the positioning block 204 is fixedly connected to a laser positioner 206. The frame 100 is provided with a needle bed 108 adapted to the quilting head 105. Receivers 207 that cooperate with the laser positioner 206 are provided on both sides of the needle bed 108. By setting the cooperation between the laser positioner 206 and the receiver 207, the position of the quilting head 105 can be detected. When the laser positioner 206 detects that the quilting head 105 is moving laterally to sew, it determines that the head is moving and approaches the press head 203, and applies greater pressure.

[0027] Through the coordinated operation of the laser positioner 206 and the receiver 207, the control system can predict the movement trend of the quilting head 105 and dynamically adjust the pressure distribution of each pressure head 203 accordingly. For example, when the quilting head 105 is sewing horizontally to the left at high speed, it will generate a continuous leftward pulling force on the mattress textile 101. At this time, the control system will in advance instruct the pressure heads 203 in the left area to increase the downward pressure, while the pressure heads 203 in the right area can appropriately reduce the pressure, forming a pressure gradient opposite to the sewing direction, effectively resisting the micro-slippage of the fabric. When the quilting head 105 accelerates or decelerates rapidly, the system will calculate the magnitude of the inertial force based on the acceleration sensor data and adjust the instantaneous pressure of each area's pressure head 203 accordingly to achieve dynamic balance.

[0028] Furthermore, the drive assembly is slidably connected to the piston rod 302 within the cavity 409. A hinge seat 303 is fixedly connected to the end of the piston rod 302 away from its piston end. A crank 304, rotatably connected to the hinge seat 303, is rotatably connected to the outer surface of the cam rod 301. An air cylinder 307 is fixedly connected to the top of the positioning block 204. A matching limiting rod 308 is slidably connected to the top of the air cylinder 307, and the limiting rod 308 is fixedly connected to the bottom of the pressure head 203. A telescopic tube 306 communicating with the cavity 409 is connected to one side of the air cylinder 307. As the pressure head 203 moves downward, it will apply greater pressure to the mattress textile 101. At this time, the limiting rod 308 will transport the gas in the compression cylinder 307 to the cavity 409 through the telescopic tube 306. The piston rod 302 is set to be forceful and drive the hinge seat 303 to move, which in turn drives the cam rod 301 to rotate through the crank 304, causing the tightening roller 300 to rotate on the surface of the mattress textile 101. At this time, the pressure head 203 at this location applies greater pressure to the mattress textile 101 and also drives the tightening roller 300 to rotate, thus tightening the fabric of the mattress textile 101.

[0029] When the pressure head 203 moves downward to apply greater pressure to the mattress textile 101, the limiting rod 308 moves downward within the air cylinder 307. The compressed air in the air cylinder 307 is then transported to the cavity 409 through the telescopic tube 306, pushing the piston rod 302 to move. This, in turn, drives the crank 304 to swing via the hinge seat 303, ultimately causing the cam rod 301 to rotate the tightening roller 300 on the surface of the mattress textile 101. This design achieves coordinated control of pressure and tension: while the pressure head 203 applies greater pressure, it automatically drives the tightening roller 300 to rotate and tighten the fabric of the mattress textile 101, creating a synergistic fixing effect. Specifically, first, the control system drives the displacement frame 201 to move the slipper 202, causing the carrier frame 200 to move laterally out of the work area; then, the mattress textile 101 to be sewn is laid flat on the surface of the carrier frame 200; next, the carrier frame 200 returns to the work position under the drive of the displacement frame 201.

[0030] The control system activates multiple adjusting cylinders 205, causing each pressure head 203 to move downwards according to a preset program, performing regional compression and fixation on the mattress textile 101. At this time, the laser positioner 206 continuously emits laser light and works in conjunction with the receiver 207 to construct a real-time position map of the quilting machine head 105.

[0031] When the quilting head 105 starts sewing, the control system adjusts the lateral position of the quilting head 105 according to the sewing trajectory plan through the first linear module 106 and the vertical height of the quilting head 105 through the second linear module 107. At the same time, the control system coordinates the longitudinal position of the host 102 and the needle bed 108 through the first guide frame 103 and the third linear module 110 to ensure that the quilting head 105 and the needle bed 108 always maintain a precise relative position.

[0032] During the sewing process, when the quilting machine head 105 performs high-speed sewing to the left, the laser positioning system detects this movement trend in real time. The control system predicts that a pulling force to the left will be generated, and then instructs the adjusting cylinder 205 in the left area to increase the thrust, causing the corresponding pressure head 203 to move down and increase the pressure. At the same time, the downward movement of these pressure heads 203 drives the limiting rod 308 to move within the air cylinder 307. The compressed gas enters the cavity 409 through the telescopic tube 306, pushing the piston rod 302 to move. Through the hinge seat 303 and the crank 304, the cam rod 301 is driven to rotate, causing the tightening roller 300 to rotate in the direction that counteracts the pulling force, thus actively tightening the surface of the mattress textile 101.

[0033] In summary, the dual-guide support structure consisting of frame 100, first guide frame 103, second guide frame 109, and main unit 102, combined with the three-dimensional motion system formed by cross frame 104, first linear module 106, and second linear module 107, achieves precise positioning and stable movement of the quilting head 105 in three-dimensional space, significantly improving the accuracy and consistency of the sewing trajectory. The cooperation between guide frame 111 and third linear module 110 ensures that the needle bed 108 can move synchronously with the quilting head 105, maintaining an ideal sewing geometry and effectively solving the problem of stitch deviation during complex pattern weaving. The multi-point fastening system achieves precise regional fixation of the mattress textile 101 through multiple pressure heads 203 evenly distributed on the carrier frame 200. Combined with the adjustment component consisting of positioning block 204 and adjustment cylinder 205, it can dynamically adjust the pressure distribution of each pressure head 203 according to the real-time position and movement direction of the quilting head 105, forming an adaptive pressure field that counteracts the sewing tension. The intelligent monitoring network composed of laser positioner 206 and receiver 207 can accurately capture the movement trend of quilting head 105, enabling the system to predict and counteract non-uniform tension generated during sewing, effectively preventing fabric micro-slippage. The tension compensation system, through a mechanical linkage mechanism formed by tension roller 300, cam rod 301, piston rod 302, hinge seat 303, and crank 304, intelligently converts the downward pressure of press head 203 into fabric tension, achieving a dynamic balance between pressure and tension. The pneumatic transmission system composed of air cylinder 307, limit rod 308, and telescopic tube 306 allows the vertical displacement of press head 203 to automatically adjust the rotation angle and direction of tension roller 300, ensuring the fabric maintains optimal tension at different sewing stages.

[0034] Example 2: Please refer to Figure 1 - Figure 10The present invention also provides a technical solution, which differs from the technical solution of Embodiment 1 as follows: a single-needle machine for weaving mattress textiles, further comprising a vibration-absorbing anchor system, which includes a positioning pressure plate 400 disposed below the pressure head 203 and connected by a telescopic soft pad 401. A cavity 409 is formed inside the pressure head 203, and a pressure relief groove 408 is formed inside the pressure head 203 for the telescopic soft pad 401 to communicate with the cavity 409. Multiple thin pressure rods 402 are slidably connected inside the positioning pressure plate 400. An anchoring assembly is provided inside the pressure head 203 to drive the multiple thin pressure rods 402 to move. By setting the positioning pressure plate 400, the mattress can be positioned... The auxiliary fixation of the mattress textile 101, in conjunction with the telescopic soft pad 401, has a vibration absorption function. When the quilting head 105 sews the mattress textile 101, the edge of the mattress textile 101 will vibrate. The positioning pressure plate 400 can absorb the vibration and act on the telescopic soft pad 401, causing the gas inside to flow through the pressure relief groove 408 into the cavity 409. When the air pressure enters the pressure relief groove 408 through the telescopic soft pad 401, the kinetic energy is destroyed, thereby reducing the vibration. The anchoring component can drive multiple thin pressure rods 402 to move, thereby strengthening the fixation of the mattress textile 101.

[0035] Furthermore, the anchoring component has a side groove 407 inside the pressure head 203 and communicating with the pressure relief groove 408. The pressure head 203 has a cavity 406 inside that communicates with the side groove 407. One side of the cavity 406 is connected to a back pressure groove 404. The telescopic cushion 401 is provided with a common connecting plate 403 connected to multiple thin pressure rods 402. One end of the back pressure groove 404 is provided with a telescopic pressure rod 405 connected to the common connecting plate 403. By setting the side groove 407 and the pressure relief groove 408... 08 is connected, and the gas that can be transmitted by the vibration force of the telescopic soft pad 401 flows into the side groove 407, and then through the confluence cavity 406 and the back pressure groove 404 into the telescopic pressure rod 405, so that it is compressed by force and squeezes the common plate 403 to move down, thereby causing multiple thin pressure rods 402 to protrude from the surface of the positioning pressure plate 400. When the positioning pressure plate 400 is vibrated and moves, the multiple thin pressure rods 402 extend and continuously abut against the mattress textile 101 to prevent the fabric from being misaligned.

[0036] The pressure relief groove 408 has a side pressure groove 410 on one side, and the side pressure groove 410 is connected to the cavity 409. The piston end of the piston rod 302 can block the pressure relief groove 408. The piston end of the piston rod 302 has multiple narrowing holes 305. By setting the narrowing holes 305, kinetic energy can be absorbed. The damping force of the telescopic soft pad 401 can be adjusted by changing the position of the piston end of the piston rod 302.

[0037] Through the fluid communication between the side groove 407 and the pressure relief groove 408, when the positioning pressure plate 400 is vibrated, the gas generated by the compression of the telescopic soft pad 401 can flow into the side groove 407, then converge through the confluence cavity 406, and enter the back pressure groove 404 to push the telescopic pressure rod 405. The telescopic pressure rod 405 contracts under the action of air pressure, thereby driving the common plate 403 to move downward, so that multiple thin pressure rods 402 simultaneously protrude from the bottom surface of the positioning pressure plate 400, forming a micro-dot array anchoring structure.

[0038] Furthermore, a controller 411 is provided on the top of the pressure head 203. The controller 411 is used to detect the flow of the medium in the pressure relief groove 408. A micro air pump 412 is fixedly connected to the top of the pressure head 203. An air nozzle 414 is rotatably connected to one end of the pressure head 203. The output end of the micro air pump 412 is connected to the air nozzle 414 through an air supply pipe 413. An adjusting handle 415 is rotatably connected to one end of the positioning pressure plate 400 and is rotatably connected to the air nozzle 414. By setting the air nozzle 414 and the micro air pump 412 to cooperate, gas can be discharged to further suppress vibration. At the same time, the quilting head 105 can be cooled and dissipated. The adjusting handle 415 can adjust the position of the air nozzle 414, and the controller 411 can detect the flow in the pressure relief groove 408.

[0039] Through the coordinated operation of the air nozzle 414 and the micro air pump 412, a directional airflow can be injected into the quilting head 105 area, achieving a dual function: on the one hand, the airflow can carry away the heat generated by the high-speed operation of the quilting head 105, effectively preventing needle breakage and thread snagging caused by overheating of the needle; on the other hand, by analyzing the vibration characteristics within the pressure relief groove 408 through the controller 411, the system can inject a reverse airflow towards the vibration crest to generate a counteracting force, further suppressing vibration propagation. The mechanical linkage design of the adjusting handle 415 enables the air nozzle 414 to automatically track the position of the quilting head 105: when the positioning pressure plate 400 is vibrated, it indicates that the quilting head 105 is approaching this area. At this time, the adjusting handle 415 automatically adjusts the air nozzle 414 to rise and face the quilting head 105, providing precise cooling and vibration suppression.

[0040] Specifically, when the quilting machine head 105 starts working, the monitoring network consisting of the laser positioner 206 and the receiver 207 tracks the position of the machine head in real time. As the quilting machine head 105 sews at high speed to the left, the system predicts that the left area will bear greater tension, and the adjusting cylinder 205 of the left presser head 203 increases the thrust, driving the presser head 203 to move downward.

[0041] At this time, the pressure head 203 moves downward, pushing the piston rod 302 to move, which in turn drives the hinge seat 303 to tilt the crank 304, driving the cam rod 301 to rotate, causing the tightening roller 300 to rotate and tighten the fabric of the mattress textile 101. Simultaneously, the movement of the piston rod 302 precisely positions the piston end at the connection between the pressure relief groove 408 and the cavity 409, blocking the main channel and creating a unique connection between the side pressure groove 410 and the pressure relief groove 408. This flow channel reconstruction significantly increases the damping force of the telescopic cushion 401, greatly improving its shock absorption effect.

[0042] Because the main connection between the pressure relief groove 408 and the cavity 409 is closed, the airflow can only flow through the narrow side pressure groove 410, the flow rate is reduced, and some of the air pressure energy is guided to the side groove 407, and then enters the back pressure groove 404 through the confluence cavity 406, pushing the telescopic pressure rod 405 to retract, driving the common plate 403 to move down, and finally causing multiple thin pressure rods 402 to extend synchronously out of the bottom surface of the positioning pressure plate 400, forming a high-density anchor point array, and implementing micro-level fixation of the mattress textile 101.

[0043] The controller 411 continuously monitors the gas flow parameters within the pressure relief groove 408 and the back pressure groove 404. When an abnormal vibration mode is detected, it automatically starts the micro air pump 412 to deliver compressed air to the air nozzle 414. Simultaneously, the slight displacement of the positioning pressure plate 400 caused by vibration is transmitted through the adjusting handle 415, automatically adjusting the orientation of the air nozzle 414 so that the cooling airflow is precisely aimed at the needle bar area of ​​the quilting head 105. This closed-loop control system not only effectively suppresses vibration but also prevents needle overheating, extends equipment life, and improves sewing quality.

[0044] In summary, the multi-stage energy dissipation structure, consisting of the positioning pressure plate 400, the telescopic soft pad 401, the pressure relief groove 408, and the cavity 409, effectively absorbs and converts the high-frequency vibration energy generated during high-speed sewing by the quilting machine head 105. When the vibration is transmitted to the positioning pressure plate 400, the gas inside the telescopic soft pad 401 is pressurized and flows through the pressure relief groove 408. The airflow resistance converts the vibration kinetic energy into heat energy, significantly reducing the vibration amplitude. The anchoring component, through the flow channel design of the side groove 407, the confluence cavity 406, and the back pressure groove 404, intelligently guides some of the vibration energy to the telescopic pressure bar 405, driving the common plate 403 to automatically extend multiple thin pressure bars 402, forming a micro-anchor point array, achieving an adaptive fixing mechanism where the greater the vibration, the stronger the anchoring. The coordinated design of the side pressure groove 410 and the narrowing hole 305 on the piston rod 302 enables the system to dynamically adjust its damping characteristics according to the sewing conditions. It provides strong damping during high-speed sewing and reduces damping during fine sewing to ensure optimal sewing results. The controller 411 monitors the system's vibration status in real time and intelligently controls the micro air pump 412 to deliver airflow to the air nozzle 414 through the air supply pipe 413. This not only actively suppresses vibration but also automatically adjusts the airflow direction to precisely cool the quilting head 105 through the linkage mechanism between the adjusting handle 415 and the positioning pressure plate 400.

[0045] Example 3: Please refer to Figure 1 - Figure 10 The present invention also provides a technical solution, which differs from the technical solution of Embodiment 1 as follows: a method for weaving mattress textiles, comprising the following steps: S1. In use, firstly, operate the displacement frame 201 to drive the sliding shoe 202 to move, thereby changing the position of the carrier frame 200. Then, place the mattress textile 101 in the carrier frame 200. After that, open multiple adjustment cylinders 205 to allow the pressure head 203 to move down and squeeze the mattress textile 101, thereby fixing the mattress textile 101. Then, operate the quilting head 105 to sew the mattress textile 101. The first straight module 106 can adjust the lateral position of the quilting head 105, the second straight module 107 can adjust the height position of the quilting head 105, and the first guide frame 103 can adjust the longitudinal position of the quilting head 105. S2. The laser positioner 206 can release a laser and cooperate with the receiver 207 to determine the position of the quilting head 105. When the quilting head 105 is sewing, for example, when it is sewing to the left, it will generate a continuous leftward pulling force on the fabric. At this time, the pressure head 203 located on the left side is adjusted to press down, thereby instantly increasing the pressure. At the same time, the piston end of the drive limit rod 308 moves in the air cylinder 307, thereby squeezing the gas in the air cylinder 307 into the cavity 409 through the telescopic tube 306. At this time, the piston rod 302 is pushed to move, thereby driving the hinge seat 303 to push the crank 304 to tilt, thereby driving the cam rod 301 to rotate, causing the tightening roller 300 to rotate and tighten the fabric. At the same time, the movement of the piston rod 302 will be located at the connection between the pressure relief groove 408 and the cavity 409, so that the side pressure groove 410 and the pressure relief groove 408 are connected to transport gas, thereby increasing the damping force of the telescopic soft pad 401, thereby improving the shock absorption effect. S3. At the same time, since the connection between the pressure relief groove 408 and the cavity 409 is closed, the narrowing of the individual side pressure groove 410 will slow down the gas flow in the pressure relief groove 408, so that some gas enters the side groove 407 and then enters the back pressure groove 404 through the confluence cavity 406, causing the telescopic pressure rod 405 to be squeezed by the gas and drive the common plate 403 to move down, and finally causing multiple thin pressure rods 402 to extend out of the positioning pressure plate 400, thereby forming multiple anchor points to further fix the fabric. S4. The controller 411 can detect the flow of the medium in the back pressure groove 404, thereby controlling the micro air pump 412 to operate and supply gas through the air supply pipe 413 into the air nozzle 414. When the positioning pressure plate 400 is vibrated, the orientation of the air nozzle 414 will be changed by adjusting the handle 415. As the vibration force on the positioning pressure plate 400 increases, the quilting head 105 will move closer to the pressure head 203, causing the air nozzle 414 to be adjusted and raised to move closer to the quilting head 105 for cooling. The vibration feedback of the positioning pressure plate 400 will be detected by the controller 411, which will then control the micro air pump 412 to operate and apply air to suppress the vibration.
