DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 A yarn pressing mechanism for a weft-insertion warp knitting machine includes a fixed shaft 1 and a moving carriage 101. A first pressing frame connecting bracket 11 and a second pressing frame connecting bracket 12 are rotatably mounted on either side of the bottom of the moving carriage 101. A pressing frame 10 is mounted between the first pressing frame connecting bracket 11 and the second pressing frame connecting bracket 12, and a yarn guide plate 15 is disposed at the bottom of the pressing frame 10. A first rotating shaft 8 is mounted on the first pressing frame connecting bracket 11, and a guide wheel mounting bracket 7 is disposed at the other end of the first rotating shaft 8. A guide wheel 4 is rotatably mounted on the top of the guide wheel mounting bracket 7. A guide groove block 3 is fixedly mounted on the fixed shaft 1, and a guide groove 31 is defined within the guide groove block 3. The guide wheel 4 moves within the guide groove 31.

[0021] Among them, the fixed sleeve is provided with a guide groove block fixing bracket 2 on the fixed shaft 1, and the bottom of the guide groove block fixing bracket 2 is fixedly provided with a guide groove block 3. Through the setting of the guide groove block fixing bracket 2, the guide groove block 3 can be fixedly installed on the fixed shaft 1.

[0022] A guide wheel pin 5 is rotatably mounted on the top of the guide wheel mounting bracket 7. A guide wheel 4 is rotatably mounted on the guide wheel pin 5 via a bearing 20. The guide wheel 4 is movable within the guide groove 31. A spacer 6 is fixedly mounted on the guide wheel pin 5 outside the guide groove 31. The spacer 6 prevents the guide wheel 4 from falling out of the guide groove 31.

[0023] A second rotating shaft 13 is rotatably mounted on one side of the bottom of the moving vehicle 101 via a bearing 20, and the other end of the second rotating shaft 13 is inserted into the second pressing frame connecting bracket 12. The fixed connection between the second rotating shaft 13 and the second pressing frame connecting bracket 12 allows the second pressing frame connecting bracket 12 to rotate via the second rotating shaft 13.

[0024] A first rotating shaft fixing bracket 9 is fixedly mounted on the other side of the bottom of the moving vehicle 101. A first rotating shaft 8 is rotatably mounted within the first rotating shaft fixing bracket 9 via multiple bearings 20. One end of the first rotating shaft 8 is connected to the guide wheel mounting bracket 7, and the other end of the first rotating shaft 8 is inserted into the first pressing frame connecting bracket 11. The first rotating shaft 8 is fixedly connected to the first pressing frame connecting bracket 11, allowing the first pressing frame connecting bracket 11 to rotate about the first rotating shaft 8.

[0025] The two sides of the bottom of the pressing frame 10 are fixedly provided with yarn guide plate brackets 14 downwardly, and the bottom of the yarn guide plate brackets 14 is fixedly connected to the yarn guide plate 15. Since the axes of the first rotating shaft 8 and the second rotating shaft 13 are in the same plane, the pressing frame 10 can rotate around the first rotating shaft 8 and the second rotating shaft 13, and drive the yarn guide plate 15 to rotate synchronously.

[0026] The guide wheel mounting bracket 7 is provided with a yarn pressing rod fixing block 16 on both sides. A yarn pressing cap fixing block 17 is provided downwardly from each of the yarn pressing rod fixing blocks 16, and a yarn pressing cap 18 is provided at the bottom of each of the yarn pressing cap fixing blocks 17. The arrangement of the yarn pressing rod fixing blocks 16 and the yarn pressing cap fixing blocks 17 allows the position of the yarn pressing cap 18 to be adjusted. This is prior art and will not be further elaborated.

[0027] Among them, a weft placing chain mechanism 19 is provided below the guide wheel mounting bracket 7 . When the guide wheel 4 moves toward the inside of the guide groove 31 , the yarn pressing cap 18 moves toward the weft placing chain mechanism 19 .

[0028] In this embodiment, when the user needs to press the yarn, the moving trolley 101 can drive the pressing frame 10 and the yarn guide plate 15 to move synchronously, thereby driving the guide wheel mounting bracket 7 on one side of the moving trolley 101 to move synchronously.

[0029] In this way, the guide wheel 4 on the guide wheel mounting bracket 7 can be moved in the guide groove 31 in the guide groove block 3. Since the guide groove 31 is an inclined surface, the guide wheel mounting bracket 7 will tilt during the movement of the guide wheel 4, thereby driving the pressing frame 10, the yarn guide plate 15 and the yarn pressing cap 18 to tilt synchronously, thereby achieving yarn pressing through the yarn pressing cap 18.

[0030] Furthermore, when the guide wheel mounting bracket 7 is tilted, it can drive the first rotating shaft 8 to rotate, thereby driving the first pressing frame connecting bracket 11 and the pressing frame 10 to rotate synchronously through the rotation of the first rotating shaft 8. At this time, the first pressing frame connecting bracket 12 and the second rotating shaft 13 will rotate synchronously with the first rotating shaft 8, thereby driving the yarn guide plate 15 at the bottom of the pressing frame 10 to rotate synchronously.

[0031] In the present invention, the movement of the moving trolley 101 can drive the guide wheel 4 to move in the guide groove 31, thereby driving the yarn guide plate 15 and the yarn pressing cap 18 to rotate synchronously toward the weft laying chain mechanism 19, thereby realizing the yarn pressing step. This yarn pressing mechanism is not only simple in structure and easy to maintain, but also simple in operation and easy to use by users.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
