By setting up a coordinated structure of an installation frame, a moving positioning component, and a yarn guiding component, it solves the problems of inflexible and inaccurate yarn guiding position adjustment, easy yarn deviation and swaying, and inconvenient device installation and debugging mentioned in the background technology, and achieves the effects of flexible and accurate yarn guiding, stable yarn guiding process, and convenient installation and debugging.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn guiding device for textile machinery, comprising an installation frame, wherein a movable positioning component is assembled within the installation frame, and a yarn guiding component is provided at the front end of the movable positioning component.

[0007] The mounting frame serves as the basic support structure for the device, comprising two symmetrically distributed L-shaped mounting seats for connecting external textile equipment. The bottom of each L-shaped mounting seat has a slotted hole, which, in conjunction with bolts, allows for flexible adjustment of the device's installation position to accommodate the installation needs of different equipment. Two sliding rods are symmetrically fixed between the two L-shaped mounting seats, providing linear guidance for the sliding of the moving positioning component and ensuring stability. A through groove is formed in the middle side wall of each L-shaped mounting seat, housing a bearing. Two bearings are fitted with a single screw, which acts as a power transmission component, working in conjunction with the moving positioning component to achieve position adjustment.

[0008] The moving positioning component consists of a moving seat that is slidably fitted onto two sliding rods. Sliding grooves are correspondingly formed on the upper and lower side walls of the moving seat, and the sliding rods are embedded in these grooves to form a sliding pair, ensuring smooth sliding of the moving seat along the sliding rods. The moving seat is equipped with a horizontal drive component, which includes a drive motor. The drive end of the drive motor is coaxially fixed to the screw. When the motor operates, the screw rotates synchronously. The front and rear ends of the drive motor are fixed to a single-sided L-shaped mounting base via a connecting bracket, ensuring stable motor installation. A threaded hole is formed in the center of the side wall of the moving seat, and the screw passes through the threaded hole to form a threaded pair. When the screw rotates, the threaded transmission drives the moving seat to move horizontally along the sliding rods. A positioner is installed below the front end of the moving seat, integrating a visual positioning head and an infrared positioning head. The visual positioning head acquires images of the yarn position, and the infrared positioning head assists in distance measurement. Together, they achieve accurate identification of the yarn position, providing real-time position reference for yarn guiding.

[0009] The yarn guide assembly is supported by an L-shaped frame fixed to the front end of the movable seat. A speed reducer is installed at the front end of the L-shaped frame, which can adjust the output speed to adapt to the yarn guide speed requirements of different textile processes. The drive end of the speed reducer is connected to the yarn guide frame. One end of the yarn guide frame is fixed to a connecting block, and the rear end of the connecting block is fixed to a yarn guide sleeve. The yarn passes through the yarn guide sleeve and moves stably along the set trajectory under the drive of the yarn guide frame, thus achieving precise yarn guide.

[0011] 1. In this utility model, by constructing a collaborative system of installation frame, moving positioning component, and yarn guiding component, and utilizing the cooperation between slide rod and moving seat groove, and the transmission between screw and moving seat threaded hole, combined with drive motor drive, flexible and precise adjustment of yarn guiding position is achieved, solving the problem of inflexible yarn guiding position adjustment in existing devices, and adapting to the yarn path requirements of various textile processes.

[0012] 2. In this utility model, the positioner integrates a visual positioning head and an infrared positioning head to accurately locate the yarn position and provide real-time reference for yarn guiding; the yarn guiding component uses a deceleration driver to control the rotation of the yarn guiding frame, and the yarn guiding sleeve constrains the yarn to ensure that the yarn moves stably along the set path, solving the problems of yarn deviation and shaking in existing devices and reducing the defect rate of textile products.
