Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and in particular to a seamless polyester yarn fabric textile machine. Background Technology

[0002] Currently, textile machinery technology has made significant progress in the production of polyester yarn fabrics. Various types of textile machines are available on the market, such as water jet looms, air jet looms, and rapier looms. These machines have played an important role in improving production efficiency and fabric quality. However, as consumers' requirements for the appearance and comfort of textiles have increased, traditional textile machines still face many challenges in producing seamless polyester yarn fabrics, such as surface defects and uneven seams. In recent years, the textile industry's demand for high-precision, high-quality seamless fabrics has been growing, driving further innovation in textile machinery technology.

[0003] Currently, to solve the production problems of seamless polyester yarn fabrics, existing technologies typically employ the following solutions: First, improve the weft insertion system of the loom by optimizing airflow or water flow control to reduce yarn breakage; second, use a high-precision tension control system to ensure the stability of the yarn during the weaving process; and third, use specially designed needles or heald frames to reduce surface defects in the fabric. However, these solutions still have limitations in practical applications. For example, minor imperfections may still appear on the fabric surface, and the problem of uneven seams has not been completely solved. The maintenance cost of high-precision tension control systems is high, and the technical requirements for operators are also high. The design and manufacturing cycle of special needles is long, increasing production costs. In addition, existing equipment has high energy consumption, which is not conducive to environmental protection and sustainable development. Summary of the Invention

[0004] The purpose of this application is to provide a seamless polyester yarn fabric weaving machine to solve the problems mentioned in the background art.

[0005] This application provides a seamless polyester yarn fabric textile machine with the following technical solution: It includes a frame, a textile machine body mounted on the upper rear side of the frame, a controller mounted on the side of the textile machine body, and a support frame mounted on the upper front side of the textile machine body. It also includes a heald frame assembly housed inside the support frame, a weft insertion assembly mounted on the upper part of the frame, a tension adjustment assembly located opposite the weft insertion assembly, and a defect detection assembly mounted on the rear side of the textile machine body. The defect detection assembly includes a connecting box mounted on the rear side of the textile machine body. A connecting rod structure is mounted on one side inside the connecting box, and the connecting rod structure is connected to the side of the detection assembly. The detection assembly is installed inside the connecting box. The upper end of the rod structure is connected to the box door. The detection component includes a fixing plate, which is fixedly connected to the upper end of the connecting box. A motor is installed at the lower end of the fixing plate, and a screw is connected to the output end of the motor. A sleeve is threadedly connected to the outside of the screw.

A linear array CCD camera and an infrared thermal imager are equidistantly installed at the bottom of the moving frame, and the infrared thermal imager is connected to the outside of the linear array CCD camera. A docking strip is fixedly connected to one side of the lower end of the moving frame. The end of the docking strip away from the moving frame is fixed to the lifting block. A base is connected to the bottom of the lifting block, and the outside of the lifting block is connected to the connecting rod structure.

[0006] By adopting the above technical solution, namely the composition of heald frame assembly, weft insertion assembly, tension adjustment assembly and defect detection assembly, the problems of surface defects and uneven seams of fabric can be significantly reduced, thereby improving fabric quality. At the same time, the defect detection assembly, through the combination of connecting box, linkage structure, detection assembly and box door, forms a self-opening and closing protective structure to meet the dust protection of the defect detection assembly when defect detection is not performed.

[0007] Preferably, the linkage structure includes a vertical plate, which is bolted to one side inside the connecting box. A movable block is movably installed inside the vertical plate. A connecting rod is connected to the side of the movable block through the block body, and the outer side of the connecting rod is connected to the outside of the lifting block. A first connecting rod is rotatably connected to the outer side of the movable block.

A second connecting rod is rotatably connected to one end of the connecting piece, and the bottom of the second connecting rod is rotatably connected to a third connecting rod. The third connecting rod is rotatably connected to the outside of the first connecting rod, and the lower end of the third connecting rod is rotatably connected to the upper end of the vertical plate.

[0008] By adopting the above technical solution, namely by using the linkage drive of the detection component to drive the internal parts of the linkage structure, the linkage structure can automatically open and close the door, thus flexibly carrying out self-removal defect detection activities.

[0009] Preferably, the heald frame assembly includes a crossbeam, which is symmetrically arranged vertically. Both sides of the crossbeam are connected to the columns. Heald rods are inserted between the upper and lower sides of the columns. Heald wires are provided at equal intervals between the upper and lower heald rods, and heald wire holes are provided in the middle of the heald wires. The top of the upper crossbeam is connected to a cylinder, and the cylinder is installed on the upper end of the bracket.

[0010] Preferably, the weft insertion assembly includes a protective shell, the bottom of which is connected to the frame. Main nozzles are installed at equal intervals inside the protective shell, and each exhaust end of the main nozzle is connected to a yarn feeding pipe. The upper and lower ends of the main nozzle are connected to auxiliary nozzles. The upper auxiliary nozzle and the air inlet end of the main nozzle are connected to a first air pipe, and the lower auxiliary nozzle air inlet end is connected to a second air pipe.

[0011] By adopting the above-mentioned technical solution, namely the combination of the main nozzle and the auxiliary nozzles at the upper and lower ends, a laminar-vortex composite airflow field can be generated during yarn conveying, thereby accelerating the yarn conveying efficiency.

[0012] Preferably, the tension adjustment assembly includes a connecting frame, which is installed on the upper end of the frame. Guide rollers are distributed in an equilateral triangle inside the lower end of the connecting frame. Both ends of the guide rollers are connected to the slider. A guide rod is inserted inside the slider. The guide rod is inserted into the side of the connecting frame, and a spring is provided on the lower end of the guide rod. The bottom of the spring abuts against the tension sensor. A push rod is connected to the upper end of one side of the slider, and the top of the push rod is connected to the telescopic end of the piezoelectric ceramic actuator.

[0013] By adopting the above technical solution, three sets of tension sensors and piezoelectric ceramic actuators can form a three-dimensional tension field self-adjusting module, which can compensate for local tension fluctuations in real time according to the yarn conveying tension, thereby improving the stability of yarn conveying.

[0014] Preferably, the lifting block is arranged in the shape of a right trapezoid, and the upper end of the lifting block is arranged in the shape of a smooth inclined surface.

[0015] Preferably, the vertical plate has an integrally formed vertical groove in the middle, and the vertical plate is slidably connected to the moving block through the vertical groove in the middle.

[0016] Preferably, the connecting rod is laterally connected to one side of the moving block, and the connecting rod is connected to the smooth inclined surface of the top of the lifting block.

[0018] Preferably, the piezoelectric ceramic actuator is electrically connected to the tension sensor, and the number and position of the piezoelectric ceramic actuator and the tension sensor are consistent with those of the guide roller.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention incorporates a heald frame assembly and a weft insertion assembly. The heald frame assembly uses dual cylinders to drive variable-diameter healds, resulting in a more stable warp yarn opening. The weft insertion assembly, through a specific angle and diameter difference design between the main and auxiliary nozzles, creates a laminar-vortex composite airflow field, achieving efficient directional transport of the weft yarn. When the two work together, the precise opening of the heald frame assembly and the directional airflow of the weft insertion assembly achieve spatiotemporal matching, ensuring the positioning accuracy of the yarn in the needle area, significantly reducing defects such as skipped stitches and misaligned wefts on the fabric surface, while also reducing energy consumption. 2. This invention incorporates a tension adjustment component, namely a three-dimensional tension field self-adjustment module, which forms a closed-loop feedback system with guide rollers and tension sensors. The piezoelectric ceramic actuator can compensate for tension fluctuations in real time. When the yarn passes through the guide rollers, the spring and tension sensor work together to detect tension differences in various dimensions. The position of the guide rollers is finely adjusted by a push rod driving a slider, so that the yarn tension remains stable, avoiding yarn breakage or loosening due to excessive local tension, and significantly improving the flatness of fabric seams. 3. This invention uses a linear CCD camera and an infrared thermal imager to identify microstructural anomalies through multispectral imaging. When the CCD detects a defect of three consecutive pixels, the system automatically marks it and adjusts the air jet pressure and the needle movement trajectory to make the fabric surface smooth and flawless. 4. This invention incorporates a linkage structure and a detection component. Specifically, a motor-driven screw moves the movable frame inward, and the connecting bar transmits the motion to the lifting block, causing the lifting block to release its lifting effect on the connecting rod. Furthermore, through the lever amplification effect of the first connecting rod and the connecting plate, the second connecting rod and the third connecting rod, and the third connecting rod and the first connecting rod, the box door automatically closes. This allows the detection component to be completely stored inside the connecting box when not in operation, reducing dust adhesion and improving the accuracy of defect detection.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 10 This application will be described in further detail below.

[0023] A seamless polyester yarn fabric weaving machine, as described in the reference Figure 1 The system includes a frame 1, a textile machine body 2 mounted on the upper rear side of the frame 1, a controller 3 mounted on the side of the textile machine body 2, a support 4 mounted on the upper front side of the textile machine body 2, a heald frame assembly 5 located inside the support 4, a weft insertion assembly 6 mounted on the upper end of the frame 1, a tension adjustment assembly 7 located on the rear side of the weft insertion assembly 6, and a defect detection assembly 8 mounted on the rear side of the textile machine body 2. Specifically, the combination of the heald frame assembly 5, the weft insertion assembly 6, the tension adjustment assembly 7, and the defect detection assembly 8 can significantly reduce fabric surface defects and uneven seams, thereby improving fabric quality.

[0024] The textile machine body 2 is equipped with a knitting needle assembly, which adopts a variable diameter needle body structure. The needle tip diameter gradually changes from 80μm to 120μm. The inner wall of the needle groove is coated with a nano-diamond coating. This knitting needle assembly is consistent with the variable diameter needle body structure in the prior art. Therefore, its specific structure will not be described in detail.

[0025] Reference Figure 2 The heald frame assembly 5 includes a crossbeam 51, which is symmetrically arranged vertically. Both sides of the crossbeam 51 are connected to the columns 52 on the left and right sides. The upper and lower ends of the columns 52 are provided with insertion holes. Heald rods 53 are inserted horizontally between the adjacent insertion holes of the left and right columns 52. Heald wires 54 are provided at equal intervals between the upper and lower heald rods 53. Heald wire holes 55 are provided in the middle of the heald wires 54. The top of the upper crossbeam 51 is connected to the cylinder 56, which is installed on the upper end of the bracket 4. The heald frame assembly 5 is arranged in two sets along the inside of the bracket 4.

[0026] Reference Figure 3 The weft insertion assembly 6 includes a protective shell 61, the bottom of which is connected to the frame 1. Main nozzles 62 are installed at equal intervals inside the protective shell 61, and each main nozzle 62 is installed at an angle of 15°. Each exhaust end of the main nozzle 62 is connected to a yarn feeding pipe 63. At the same time, a magnetic levitation yarn guide can be installed on the outside of the yarn feeding pipe 63 to achieve zero-contact yarn feeding. The upper and lower ends of the main nozzle 62 are connected to auxiliary nozzles 64. The upper auxiliary nozzle 64 and the air inlet end of the main nozzle 62 are connected to a first air pipe 65, and the air inlet end of the lower auxiliary nozzle 64 is connected to a second air pipe 66. Specifically, the combination of the main nozzle 62 and the auxiliary nozzles 64 at the upper and lower ends can generate a laminar-vortex composite airflow field during yarn feeding, thereby accelerating the yarn feeding efficiency.

[0027] The main nozzle 62 is connected to the auxiliary nozzle 64 on its upper and lower sides at a 30° angle, and the inner diameter of the main nozzle 62 is larger than that of the auxiliary nozzle 64. This allows for the formation of a laminar-vortex composite airflow field, enabling efficient and rapid yarn transport.

[0028] Reference Figures 4-5The tension adjustment component 7 includes a connecting frame 71, which is installed on the upper end of the frame 1. Guide rollers 72 are distributed in an equilateral triangle inside the lower end of the connecting frame 71. Both ends of the guide rollers 72 are connected to sliders 73. Guide rods 74 are vertically inserted inside the sliders 73 on both sides. The top of the guide rods 74 are inserted into the side of the connecting frame 71, and a spring 75 is provided on the lower end of the guide rods 74. The bottom of the spring 75 abuts against the tension sensor 76. A push rod 77 is connected to the upper end of the right slider 73, and the top of the push rod 77 is connected to the telescopic end of the piezoelectric ceramic actuator 78. Specifically, the three sets of tension sensors 76 and the piezoelectric ceramic actuator 78 can form a three-dimensional tension field self-adjustment module, which can compensate for local tension fluctuations in real time according to the yarn conveying tension, thereby improving the stability of yarn conveying.

[0029] Among them, the piezoelectric ceramic actuator 78 is electrically connected to the tension sensor 76, and the number and position of the piezoelectric ceramic actuator 78 and the tension sensor 76 are consistent with those of the guide roller 72. In this way, the real-time compensation of local tension fluctuations is achieved, and the stability of yarn conveying is improved.

[0030] Reference Figures 6-8 The defect detection component 8 includes a connecting box 81, which is installed on the rear side of the textile machine body 2. A connecting rod structure 82 is installed on the left side inside the connecting box 81. The connecting rod structure 82 is connected to the side of the detection component 83, and the detection component 83 is installed inside the connecting box 81. The upper end of the connecting rod structure 82 is connected to the box door 84. Specifically, the defect detection component 8, through the combination of the connecting box 81, the connecting rod structure 82, the detection component 83 and the box door 84, forms a self-opening and closing protective structure to meet the dust protection of the defect detection component 8 when no defect detection is performed.

[0031] Reference Figure 9 The linkage structure 82 includes a vertical plate 821, which is bolted to the left side of the connecting box 81. A movable block 822 is movably installed inside the vertical plate 821. A connecting rod 823 is connected to the lower right side of the movable block 822 through the block body, and the outer side of the connecting rod 823 is connected to the outside of the lifting block 8310. A first connecting rod 824 is rotatably connected to the right side of the movable block 822. The upper end of the first connecting rod 824 is rotatably connected to the connecting piece 825, and the connecting piece 825 is bolted to the bottom of the box door 84. A second connecting rod 826 is rotatably connected to the front side of the connecting piece 825, and the bottom of the second connecting rod 826 is rotatably connected to the third connecting rod 827. The third connecting rod 827 extends obliquely and is rotatably connected to the outside of the first connecting rod 824, and is rotatably connected to the upper end of the vertical plate 821. Specifically, the linkage drive of the internal parts of the linkage structure 82 by the detection component 83 enables the linkage structure 82 to automatically open and close the box door 84, thus flexibly performing self-removal defect detection activities.

[0032] Reference Figure 10The detection component 83 includes a fixing plate 831, which is fixedly connected to the upper part of the connecting box 81. A motor 832 is provided on the front side of the lower end of the fixing plate 831. A screw 833 is connected to the output end of the motor 832. A sleeve 834 is threadedly connected to the outside of the screw 833. Telescopic rods 835 are provided on the lower ends of both sides of the fixing plate 831. The front sides of the sleeve 834 and the telescopic rods 835 are connected to the upper end of the moving frame 836. At least seven sets of linear CCD cameras 837 and infrared thermal imagers 838 are equidistantly arranged at the bottom of the moving frame 836. The infrared thermal imagers 838 are connected to the outside of the linear CCD cameras 837. A docking strip 839 is longitudinally fixedly connected to the left side of the lower end of the moving frame 836. The end of the docking strip 839 away from the moving frame 836 is fixed to the side of the lifting block 8310. The bottom of the lifting block 8310 is connected to the base 8311, and the outside of the lifting block 8310 is connected to the connecting rod structure 82.

[0033] The lifting block 8310 is arranged in the shape of a right trapezoid, and the upper end of the lifting block 8310 is arranged in a smooth inclined surface, thus satisfying the linkage lifting transmission of the moving block 822.

[0034] The vertical plate 821 has an integral vertical groove in the middle, and the vertical plate 821 is slidably connected to the moving block 822 through the vertical groove in the middle, so that the moving block 822 can move smoothly up and down vertically along the middle of the vertical plate 821; the connecting rod 823 is horizontally connected to one side of the moving block 822, and the connecting rod 823 is connected to the smooth inclined surface of the top of the lifting block 8310, so as to meet the efficient linkage activity of the detection component 83 and the connecting rod structure 82.

[0035] The implementation principle of this application embodiment is as follows: 1. The cylinder 56 drives the two sets of heald frame assemblies 5 inside the bracket 4 to move up and down alternately. In this way, the heald wires 54 inside the heald frame assembly 5 will drive the warp yarns introduced into the heald wire holes 55 to move up and down to form an opening, thereby completing the warp and weft interlacing activity. 2. When the yarn enters the weft insertion assembly 6, the air supply activities of the first air pipe 65 and the second air pipe 66 can combine the main nozzle 62, the yarn feeding pipe 63 and the auxiliary nozzle 64 to form a two-stage air jet structure to generate a laminar-vortex composite airflow field. At the same time, a magnetic levitation yarn guide is installed on the outside of the yarn feeding pipe 63 to perform zero-contact yarn feeding, thereby satisfying the stable yarn feeding. 3. The yarn output from the weft insertion assembly 6 will be stably fed into the textile machine body 2 by the three guide rollers 72 inside the tension adjustment assembly 7. The yarn will then be woven by the knitting needle assembly installed inside the textile machine body 2. At the same time, when the three guide rollers 72 are assisting in the yarn feeding activity, the tension sensors installed on the side can form a three-dimensional tension field model. Based on the yarn feeding tension detection data, the piezoelectric ceramic actuator 78 will run automatically to meet the real-time compensation for local tension fluctuations, avoid the problem of excessive or insufficient yarn feeding tension, and improve the subsequent yarn weaving quality. 4. When the yarn is finished spinning and output from inside the textile machine body 2, the microstructure abnormalities are identified by multispectral imaging of the linear CCD camera 837 and infrared thermal imager 838 installed inside the detection component 83. When the linear CCD camera 837 detects a defect of 3 consecutive pixels, the system automatically marks it and feeds back to adjust the air jet pressure and the needle movement trajectory to make the fabric surface smooth and flawless. In this way, the problems of fabric surface defects and uneven seams are significantly reduced, and the fabric quality is improved. 5. If the defect detection component 8 is not in use, prevent external dust or lint from adhering to the line array CCD camera 837 and the infrared thermal imager 838. In this case, the motor 832 can be run to rotate the output end connecting screw 833. As the screw 833 rotates, it will satisfy the inward movement of the external connecting sleeve 834. With the extension and retraction support of the telescopic rods 835 on both sides of the lower end of the fixed plate 831, the moving frame 836 can stably move the line array CCD camera 837 and the infrared thermal imager 838 into the connecting box 81. At the same time, when the moving frame 836 moves inward, the connecting strip 839 installed longitudinally on its lower left side can move inward synchronously and drive the lifting block 8310 set on the upper end of the base 8311 to move inward. The inward movement of the lifting block 8310 will release the movement block 822. The lifting effect of the connecting rod 823 on one side causes the door 84 to automatically descend under its own weight. When the door 84 descends and closes, the rotation of the connecting piece 825 and the first connecting rod 824, the second connecting rod 826 and the third connecting rod 827, and the third connecting rod 827 and the first connecting rod 824, together with the rotation of the first connecting rod 824, allows the moving block 822 to automatically move down and reset along the groove in the middle of the vertical plate 821. Thus, the connecting rod structure 82 can be protected by the inward movement of the linear CCD camera 837 and the infrared thermal imager 838, while simultaneously closing the door 84. This keeps the linear CCD camera 837 and the infrared thermal imager 838 stably positioned inside the connecting box 81 and the door 84, reducing the impact of external dust adhesion and improving the accuracy of subsequent defect detection.
