Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn guiding device. Background Art

[0002] The yarn guide device in the textile machinery ensures that the yarn passes through each process link smoothly during the entire textile process through components such as yarn guides, tension adjustment devices, yarn guide plates and yarn guide channels. The structural principles of the yarn guide device include yarn guiding, tension adjustment, yarn guide channel design and automated control to maintain the proper tension and uniform flow of the yarn, and ultimately form high-quality textiles, wherein the yarn passes through the holes in the yarn guide and is guided by the yarn guide plate to pass through each process part along a predetermined path, and the tension adjustment device adjusts the tension of the yarn to ensure that the yarn will not break or be over-tensioned during high-speed movement, and to maintain appropriate textile conditions. For example, a yarn guide device disclosed in the authorization announcement number CN214989346U includes a bracket, at least one fixed tension rod and a tension adjustment assembly, wherein the two ends of the fixed tension rod are connected to the bracket. The two sides of the frame are fixedly connected, and the two ends of the tension adjustment component are rotatably connected to the bracket. The tension adjustment component is arranged parallel to the fixed tension rod. It adjusts the position of the rotating tension rod by adjusting the installation angle of the rotating frame, thereby realizing precise control of the yarn tension. However, this technical solution requires the arrangement of a motor with shaft self-locking and rotation drive functions. Only this type of motor can drive the tension adjustment component to rotate. When multiple yarn guide devices of this type are arranged in a textile machinery, the system using this type of motor requires more precise control to ensure that the yarn maintains a constant tension throughout the process, which greatly increases the cost of the device and the complexity of the system.

[0020] The yarn to be used is wound out from the bottom of the transverse moving tensioning assembly, and one end of the yarn is wound out from the inside of the double roller routing structure, the lower surface of the front C-shaped yarn guide plate 5 and the upper surface of the rear U-shaped yarn guide plate 6 in sequence, and then the yarn is wound from the lower surface of the yarn running roller 4 into the next transverse moving tensioning assembly;

[0021] A front C-shaped yarn guide plate 5 is fixed on the surface of the vertical plate 2 between the rear U-shaped yarn guide plate 6 and the U-shaped roller frame 8, and a lifting lug is provided at one end of the front C-shaped yarn guide plate 5 away from the vertical plate 2;

[0022] The transverse movement tensioning assembly includes a right-angle arm 701 installed on the surface of the slide 7, and a rotatably installed crimping roller 702 inside the right-angle arm 701. The transverse movement tensioning assembly also includes a telescopic driving structure 9 arranged on one side of the surface of the vertical plate 2. The telescopic driving structure 9 is used to pull the slide 7 to move. The telescopic driving structure 9 includes a convex character seat 901 installed on one side of the surface of the vertical plate 2, and an electric telescopic rod 902 installed on the outer wall of one side of the convex character seat 901. The top end of the piston rod of the electric telescopic rod 902 is fixedly connected to the outer wall of one side of the slide 7.

[0023] The yarn is wound from the lower surface of the pressure roller 702 into the space between the upper roller 801 and the lower roller 802, and the end of the yarn is wound from the bottom of the front C-shaped yarn guide plate 5, the upper surface of the rear U-shaped yarn guide plate 6 and the lower surface of the yarn running roller 4, and the slide 7 is pulled away from or close to the U-shaped roller frame 8 by the convex seat 901, so as to adjust the distance between the pressure roller 702 and the upper roller 801, thereby realizing the tensioning function of the yarn;

[0024] A rectangular rail is provided on one side of the surface of the vertical plate 2, and a slider that slides with the rectangular rail is fixed on the back of the slide 7. The rectangular rail provides a larger contact area, making the slide 7 more stable during the sliding process. This design can effectively reduce friction and shaking, ensuring that the movement of the slide 7 is more precise, especially in the textile process that requires precise control, which helps to ensure the accurate positioning of each component; at the same time, the structure of the rectangular rail can better resist lateral loads, and even the lateral force generated during the working process can be effectively supported;

During this process, the staff can open the transverse tensioning assembly to make itself have a certain distance from the U-shaped roller frame 8 and the double-roller routing structure, so that the yarn in an inclined state is tensioned. During this process, the movement of the pressure roller 702 is controlled by the transverse tensioning assembly, so that the yarn can be effectively tensioned, ensuring its smooth transmission in the weaving process, improving production efficiency, and compared with the previous complex motor system, the maintenance cost is lower, which means less downtime and easier to manage maintenance work, thereby improving the reliability and maintainability of the production line.
