Description

Technical Field

[0001] This invention belongs to the field of textile machinery technology, and in particular relates to a combined yarn carrier and yarn guiding method. Background Technology

[0002] Two-dimensional braiding involves a yarn carrier driven by a dial to move in an "∞" shape around a central axis within a guide groove on a base. To avoid interference between yarn carriers during this "∞" shape movement, existing yarn carriers integrate the yarn storage disc, tension control, and yarn guiding mechanism. This approach severely restricts the size and layout of the yarn carrier, impacting its operating environment. Particularly in applications requiring high-speed, high-capacity, and continuous braiding (such as cable products), its low flexibility and limited operating environment significantly restrict braiding efficiency and product diversity. Therefore, it is necessary to develop a modular yarn carrier to meet the demands of high-speed, high-capacity, and continuous braiding, adapting it to applications such as continuously formed cable products. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides a combined yarn carrier and a yarn guiding method.

[0004] The technical solution adopted in this invention is: A combined yarn carrier, comprising: The yarn storage and carrying device is used to store yarn and move along the first guide groove according to a preset trajectory during the weaving process; The tension yarn carrier is used to adjust and control the tension of the yarn and move along the second guide groove according to a preset trajectory. The yarn storage and carrying device and the tension yarn carrying device are two independent and separate components. They are connected by yarn and used in combination to guide the yarn to the weaving area to participate in the weaving process.

[0005] Furthermore, the yarn storage and carrying device includes a yarn storage slider, a base, a yarn guide bracket, a yarn storage disc, and a disc fixing bracket; the yarn storage slider is fixedly installed below the base and slides in cooperation with the first guide groove to guide the yarn storage and carrying device during weaving; the base is provided with a yarn storage shaft, the yarn storage disc is rotatably installed on the yarn storage shaft, and the disc fixing bracket is fixedly installed above the yarn storage disc through the yarn guide bracket to guide the yarn out of the yarn storage disc and control the yarn release of the yarn storage disc.

[0006] Furthermore, the yarn guide bracket is equipped with a yarn guide ceramic eye for yarn feeding.

[0007] Furthermore, the yarn guide bracket includes a reversing guide wheel, a yarn feeding tension wheel assembly, a yarn guide ring, and a tension wheel guide groove. One end of the yarn guide ring is connected to the upper end of the yarn storage shaft, and the other end is hinged to the yarn guide bracket via a hinge shaft. The reversing guide wheel is rotatably mounted on the yarn guide ring and cooperates with the yarn feeding tension wheel assembly for yarn guidance. The yarn feeding tension wheel assembly is slidably mounted on the yarn guide ring via the tension wheel guide groove and is used to control the yarn feeding from the yarn storage head.

[0008] Furthermore, the yarn guide wheel corresponds to the yarn guide eye and is used for yarn guidance.

[0009] Furthermore, the yarn feeding tension wheel assembly includes a tension wheel, a tension wheel bracket, and a stop button. The tension wheel is rotatably mounted on the tension wheel bracket via a wheel axle. The tension wheel bracket is slidably connected to the head fixing ring via a tension wheel guide groove. A stop button is provided at the lower end of the tension wheel bracket. The stop button engages with the groove teeth at the upper end of the yarn storage head and provides pre-pressure through a spring to control the yarn feeding from the yarn storage head.

[0010] Furthermore, the tension yarn carrier includes a tension yarn carrier base and a tension control mechanism mounted thereon. The tension yarn carrier base is used to guide the yarn into the tension control mechanism and slides with the second guide groove to provide guidance for the tension yarn carrier during weaving. The tension control mechanism is used to guide the yarn into the weaving area and control the yarn tension.

[0011] Furthermore, the tension yarn carrier base includes a tension slider, an inlet yarn guide ceramic eye, a positioning flange, a guide shaft, and an outlet yarn guide ceramic eye; the upper and lower ends of the guide shaft are respectively fixedly connected to two positioning flanges, and its lower end passes through the lower positioning flange and is fixedly connected to the tension slider, and the tension slider is slidably engaged with the second guide groove; the outlet yarn guide ceramic eye is located on the upper positioning flange, the inlet yarn guide ceramic eye is located on the tension slider, and the guide shaft is a hollow shaft, with its upper and lower ends communicating with the outlet yarn guide ceramic eye and the inlet yarn guide ceramic eye, respectively.

[0012] Furthermore, the tension control mechanism includes a guide slider, a movable pulley assembly fixed on the guide slider, a guide pillar slidably connected to the guide slider, a guide limiting block fixed to the upper end of the guide pillar, a fixed pulley assembly and a yarn outlet eye fixed on the guide limiting block, and a tension spring fitted on the guide pillar with its two ends connected to the guide slider and the guide limiting block respectively.

[0013] A yarn guiding method, based on any of the above-mentioned combined yarn carriers, includes: The yarn storage and carrying device moves along the first guide groove along a preset trajectory; the tension yarn carrying device moves along the second guide groove along a preset trajectory. During this process, the yarn is drawn from the yarn storage disc of the yarn storage and carrying device, passes through the yarn guide ceramic eye, and successively passes through the reversing yarn guide wheel and the yarn feeding tension wheel group. After reversing direction, it enters the tension yarn carrying device from the inlet yarn guide ceramic eye. In the tension yarn carrier, the yarn passes through the inlet guide eye, guide shaft and outlet guide eye of the tension yarn carrier base in sequence, enters the tension control mechanism, passes around the movable pulley group and the fixed pulley group in sequence to adjust the tension, and finally passes through the outlet eye to participate in weaving.

[0014] The beneficial effects of this invention are: 1) The yarn carrier adopts a combined form, separating the yarn storage and tension control functions to avoid mutual interference and space limitations of the integrated form, making each part more complete and the functions more specific; 2) The separate yarn guide path is adopted to isolate the two functions of yarn storage and release and tension control, thereby reducing the difficulty of tension control; 3) The modular yarn carrier is more flexible in use, can achieve a larger yarn storage capacity, and is suitable for high-speed continuous weaving of ultra-long cable products, thereby improving weaving efficiency and reducing weaving costs.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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. Example 1

[0022] like Figure 1 As shown, this embodiment provides a combined yarn carrier, including a yarn storage carrier 1 and a tension carrier 2. The two carriers operate independently within their respective guide grooves 4 and are used together in combination. The yarn storage carrier 1 is used for storing and releasing yarn, while the tension carrier 2 is used for controlling weaving tension.

[0023] See Figure 2 and Figure 3 The yarn storage and carrying device 1 includes a yarn storage slider 11, a base 12, a yarn guide bracket 13, a yarn storage disc 14, and a disc fixing bracket 15. The slider 11 is fixedly installed at the lower end of the yarn storage shaft on the base and moves within the guide groove of the weaving equipment, providing guidance for the yarn storage and carrying device 1 to follow a predetermined weaving trajectory. The weaving base 12 supports all components of the entire yarn storage and carrying device 1 and has a yarn storage shaft on it for placing the yarn storage disc 14. The yarn storage disc 14 can rotate around the yarn storage shaft to release yarn. The yarn guide bracket 13 extends axially along the yarn storage disc 14 and is fixed to the weaving base 12. A yarn guide ceramic eye 131 is installed in its middle to guide the yarn and reduce its wear.

[0024] In this embodiment, the yarn guide bracket 15 is located at the upper end of the yarn guide bracket 13 and includes a yarn guide wheel 151, a yarn feeding tension wheel group 152, a yarn guide ring 153, and a tension wheel guide frame 154.

[0025] One end of the yarn storage head fixing ring 153 is fitted onto the upper end of the yarn storage shaft and locked with a nut; the other end is hinged to the upper end of the yarn guide bracket 13 via a hinge shaft; when the yarn storage head fixing ring 153 is released, the yarn storage head fixing bracket 15 can be opened around the hinge shaft to perform the operation of replacing the yarn storage head 14; when the yarn storage head fixing ring 153 is locked to the yarn storage shaft, it can effectively prevent the yarn storage head 14 from detaching during the weaving process.

[0026] The yarn guide wheel 151 is rotatably mounted on the disc head fixing ring 153, corresponding to the yarn guide ceramic eye 131, and is used for yarn guidance.

[0027] The yarn feeding tension wheel assembly 152 includes a tension wheel, a tension wheel bracket 155, and a stop button 1551 fixedly mounted at the bottom of the tension wheel bracket. The tension wheel is rotatably mounted on the upper end of the tension wheel bracket 155 via its axle, and is used to guide the yarn when it is drawn out from the yarn storage and carrying device 1. The tension wheel guide frame 154 is fixed on the head fixing ring 153. The tension wheel bracket 155 is fitted outside the head fixing ring 153 and is slidably connected to the tension wheel guide frame 154. The tension wheel guide frame 154 has a guide groove 1541, and the tension wheel shaft is slidably disposed in the guide groove 1541. The stop button 155 engages with the groove teeth 141 at the upper end of the yarn storage head 14 and provides preload through a spring (not shown in the figure) to control the yarn feeding from the yarn storage head 14. In practice, the spring is slidably mounted on the stop button 155, with its upper end abutting against the tension wheel bracket. During the weaving process, when the yarn tension causes the tension wheel to move upward a certain distance in the tension wheel guide groove 154, the stop button 155 disengages from the groove tooth 141, and yarn release begins. When the weaving tension of the yarn decreases, the stop button 155 resets under the action of the spring and re-engages with the groove tooth 141, stopping the yarn release.

[0028] See Figure 1 and Figure 3 In this embodiment, the tension yarn carrier 2 includes a tension yarn carrier base 21 and a tension control mechanism 22 mounted thereon. The tension yarn carrier base 21 includes a tension slider 211, an inlet yarn guide eye 212, a positioning flange 213, a guide shaft 214, and an outlet yarn guide eye 215. The two positioning flanges 213 are fixedly connected in parallel by the guide shaft 214 to form the main body of the base. The upper end of the guide shaft 214 is connected to the upper positioning flange, and the lower end passes through the center of the lower positioning flange and is fixedly connected to the tension slider 211. The outlet yarn guide eye 215 is located at the center of the upper positioning flange, and the inlet yarn guide eye 212 is located at the center of the bottom surface of the tension slider 211. The guide shaft 214 is a hollow shaft, and its upper and lower ends are respectively connected to the outlet yarn guide eye 215 and the inlet yarn guide eye 212.

[0029] The tension slider 211 works in conjunction with the positioning flange 213 and the guide shaft 214 to guide the tension yarn carrier 2 during weaving. The inlet guide eye 212 and the outlet guide eye 215 guide the yarn feed and reduce wear.

[0030] In this embodiment, the tension control mechanism 22 includes a guide slider 221, a movable pulley assembly 222, a guide support 223, a guide positioning block, a fixed pulley assembly 224, a yarn outlet ceramic eye 225, and a guide limiting block 226. The guide positioning block is horizontally fixed to the upper side of the tension yarn carrier base 21. The lower end of the guide support 223 is vertically fixed to one end of the guide positioning block, and its upper end is fixedly connected to the guide limiting block 226. A tension spring is fitted onto the guide support 223. The guide slider 221 is slidably mounted on the lower end of the guide support 223, and both ends of the tension spring freely abut against the guide limiting block 226 and the guide slider 221, respectively. The movable pulley assembly 222 is fixedly mounted on the guide slider 221 and can move axially along the guide support 223, providing pressure through the tension spring on the guide support 223. The guide limit block is L-shaped. The fixed pulley block 224 is fixed to the lower end of the guide limit block and corresponds vertically to the movable pulley block 222. The number of pulleys on both the movable pulley block 222 and the fixed pulley block 223 includes, but is not limited to, two. The yarn outlet ceramic eye 225 is fixedly installed on the upper end of the guide limit block and corresponds to the fixed pulley block 224.

[0031] During the weaving process, the yarn drives the guide slider 221 to move axially along the guide support 223 via the movable pulley block 222, and the weaving tension is controlled by spring compression. After passing through the movable pulley block 222 and the fixed pulley block 223, the yarn is led out to the forming area through the uppermost yarn exit ceramic eye 225. Example 2

[0032] This embodiment provides a method for guiding yarn using a combined yarn carrier as described in Embodiment 1, including: The yarn storage and carrying device (1) moves along the first guide groove along a preset trajectory; the tension yarn carrying device (2) moves along the second guide groove along a preset trajectory; During this process, yarn 3 is drawn out from the yarn storage disc 14 of the yarn storage and carrying device 1, passes through the yarn guide ceramic eye 131, and goes upward through the reversing yarn guide wheel 151 and the yarn feeding tension wheel group 152 in sequence. After reversing direction, it leaves the yarn storage and carrying device 1 and enters the tension yarn carrying device 2. It enters from the inlet yarn guide ceramic eye 212, passes through the guide shaft 214, and exits from the outlet yarn guide ceramic eye 215. It passes through the moving pulley group 222 and the fixed pulley group 223 in sequence, and finally exits through the outlet yarn ceramic eye 225 to enter the forming area to participate in the weaving and forming process.
