[0019] A new type of yarn guiding device for a ribbon weaving machine, such as Figures 1 to 3 As shown, a mounting frame 1 is provided, which has a groove structure. A mounting platform 6 is fixedly installed on the left side of the mounting frame 1. Insertion holes connecting to the interior of the mounting frame 1 are opened on both sides of the exterior of the mounting frame 1. A rolling shaft 8 is movably installed inside the mounting frame 1. Guide wheels 9 are arranged at equal intervals on the surface of the rolling shaft 8. The surfaces of the guide wheels 9 are recessed inward on both sides. Adjustment cavities 2 are opened on both the left and right sides of the mounting frame 1. Mounting slots 10 are opened on the upper and lower sides of the adjustment cavities 2. Fixing bolts 3 are inserted and fixedly installed inside the adjustment cavities 2. A lifting plate 4 is also provided inside the mounting frame 1. The lifting plate 4 is located above the rolling shaft 8. A guide structure 14 for pressing the yarn is provided below the lifting plate 4. The guide structure 14 corresponds to the position of the guide wheels 9.

[0020] The surface of the rolling shaft 8 is provided with locking screw holes 11 arranged at equal intervals, and the surface of the guide wheel 9 is provided with a slot corresponding to the size of the locking screw holes 11. After the guide wheel 9 is fitted onto the outside of the rolling shaft 8, it is positioned by bolts, and it is very convenient to adjust the position of the guide wheel 9.

[0021] The adjustment chamber 2 is also equipped with a compression spring 5. After the fixing bolt 3 is installed between the two mounting holes 10, the compression spring 5 is fitted on the outside of the fixing bolt 3. Both ends of the lifting plate 4 are provided with holes corresponding to the outer diameter of the fixing bolt 3. After the lifting plate 4 is installed between the two fixing bolts 3, the compression spring 5 is located above the lifting plate 4. Under normal conditions, the compression spring 5 pushes the lifting plate 4 downward to move towards the rolling shaft 8.

[0022] The lifting plate 4 has evenly spaced access slots 12 for positioning on both sides. The top of the guide structure 14 has a locking slot 15. The guide structure 14 is locked between the two corresponding access slots 12 through the locking slot 15. The top of the lifting plate 4 also has equidistantly arranged positioning screw holes 13. The bottom surface of the locking slot 15 has a hole corresponding to the size of the positioning screw hole 13. The guide structure 14 is locked below the positioning screw hole 13 by bolts.

[0023] Two tensioning rollers 16 are installed at the lower end of the guide structure 14, which are far apart from each other. After the lifting plate 4 is installed above the rolling shaft 8, the two tensioning rollers 16 are located on both sides of the corresponding guide rollers 9. When the yarn passes through the top of the guide rollers 9, the two tensioning rollers 16 descend and contact the surface of the yarn, so that the yarn is kept taut on the surface of the guide rollers 9, preventing the yarn from coming out of the interior of the guide rollers 9 during the guiding process, and achieving a good protective effect.

[0024] The working principle of this utility model:

[0025] By using a lifting plate 4 equipped with an automatic yarn tensioning mechanism, the guide structure 14 is clamped between two access slots 12 and contacts the bottom surface of the lifting plate 4. A bolt is passed through the positioning screw hole 13 and inserted into the pre-set hole on the bottom surface of the clamping slot 15 to complete the locking. Then, the two ends of the lifting plate 4 are clamped into the corresponding adjustment cavity 2. The fixing bolt 3 is inserted into the adjustment cavity 2 to restrict the two ends of the lifting plate 4. At the same time, the compression spring 5 is installed above the lifting plate 4. Under normal conditions, the lifting plate 4 will move downward due to the compression spring 5 on both sides. Multiple guide structures 14 move downward to the top of the corresponding guide wheel 9. The two tensioning wheels 16 at the bottom of the guide structure 14 form a triangular structure with the guide wheel 9. When the yarn passes through the guide wheel 9, it will be pressed downward by the two tensioning wheels 16 to fit more closely to the surface of the guide wheel 9. This prevents the yarn from detaching during the yarn guiding and conveying process, and provides a good protective effect.

[0026] With the guide wheel 9 designed for easy adjustment, its two ends gradually concave inwards. After the guide wheel 9 is fitted onto the outside of the rolling shaft 8, it can slide. The surface of the rolling shaft 8 has a pre-set locking screw hole 11 for positioning, which can adjust the position of the guide wheel 9 as needed. The guide wheel 9 can be replaced with one of appropriate size according to the thickness of the yarn. After the guide wheel 9 is installed, the drive motor 7 is started, and the locking screw hole 11 will drive the guide wheel 9 to rotate. With the help of the yarn-pressing guide structure 14, the yarn can be guided out. This device is simple in structure and easy to operate during use, and effectively reduces the occurrence of yarn detaching from the inside of the guide wheel 9 during the yarn guiding process.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
