[0002] A texturing machine is a textile mechanical equipment that can process untwisted yarns such as polyester (POY) and polypropylene into elastic yarns. It endows fibers with elasticity through processes such as stretching, heating, and deformation. The yarn guiding device is one of the core components of the texturing machine, mainly used to guide the yarn to move along a predetermined path to ensure stable yarn tension during the texturing process.

[0020] A method for using a yarn guiding device of a texturing machine, including Step S1: The device is firmly installed through the belt mounting block 2, and one end of the yarn is passed through the yarn guiding ring 11 from the left, so that the yarn is located between the bottom yarn guiding wheel 62 and the top yarn guiding wheel 63, and below the inner yarn guiding wheel 9, above the tension adjusting wheel 74, and through the yarn guiding member 6 on the right; Step S2: During the yarn guiding process, the main electric push rod 76 can be started to operate to push the square connecting rod 77 up and down, so that when the square connecting rod 77 moves, it can push the square frame 73 and the sliding cylinder 72 to move up and down along the long vertical column 71, and adjust the tension adjusting wheel 74 to a suitable position; Step S3: Cooperate with the inner yarn guiding wheels 9 on both sides to form a triangular yarn guiding path, which can adjust the yarn tension.

A secondary notch 12 adapted to the square connecting rod 77 is formed on the back surface of the yarn guide frame 1. The main notch 13 and the secondary notch 12 provide a movement space for the transmission components, preventing mechanical interference with the yarn guide frame 1 and ensuring the smooth operation of the device. A controller 3 is fixedly connected to the front surface of the yarn guide frame 1. The controller 3 is electrically connected to the tension adjusting member 7 and the driving member 4 through wires. The controller 3 uniformly controls the tension and the yarn guiding action, improving the intelligent level and processing precision of the device.

[0023] In this embodiment, a vision module is further included. The vision module includes a camera fixedly installed on one side of the yarn guide frame (1) and a processing chip. The processing chip is fixedly installed inside the camera. The processing chip is built-in with an attitude analysis unit and an attitude judgment unit. The attitude analysis unit is used to detect the combing state and the integrity state of the yarn. The attitude judgment unit is used to output the analysis result. Therefore, it can be judged whether the yarn breaks, tangles, or has other abnormal running postures during the guiding process, and a warning is issued in a timely manner to prompt the personnel to pay attention to correcting the posture of the yarn and ensure the normal guiding work of the yarn.

[0024] Working principle: When in use, install the device firmly through the belt port mounting block 2, and pass one end of the yarn through the yarn guide ring 11 from the left, so that the yarn is located between the bottom yarn guide wheel 62 and the top yarn guide wheel 63, and below the inner yarn guide wheel 9, pass above the tension adjusting wheel 74, and pass through the yarn guide member 6 on the right. During the yarn guiding process, the main electric push rod 76 can be started to operate to push the square connecting rod 77 to move up and down. When the square connecting rod 77 moves, it can push the square frame 73 and the sliding cylinder 72 to move up and down along the long vertical column 71, adjust the tension adjusting wheel 74 to a suitable position, and cooperate with the inner yarn guide wheels 9 on both sides to form a triangular yarn guiding path, which can adjust the yarn tension. When the square frame 73 drives the tension adjusting wheel 74 to rise, the yarn tension increases, and when the tension adjusting wheel 74 drops, the tension decreases.
