Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a weft yarn stabilizing device for a ribbon weaving machine. Background Technology

[0002] Traditional weft springs for ribbon looms are typically 0.8-1mm stainless steel springs, with the weft yarn passing directly through them. This has several drawbacks: ① they wear out easily and last only a few months; ② due to the small contact area, they are not very sensitive to stopping the machine when a yarn breaks. A search revealed Chinese patent publication number CN207109221U, which discloses a weft yarn flight stabilization device. This device includes a main body with mounting plates on opposite sides of its lower part. Each mounting plate has through holes with eyelets installed within them. A spring lever is also located at the bottom of the main body between two eyelets.

[0003] While the above technical solution can reduce the number of yarn breaks during loom operation and improve the operational stability of the loom, it has certain drawbacks because the weft yarn is adjusted by an elastic lever, which can easily lead to insufficient tension and make adjustment impossible.

[0006] The weft yarn stabilizing mechanism includes a second screw that is slidably connected to the outer surface of the support. One end of the second screw is fixedly connected to a frame. A slider is slidably connected inside the frame. A second ceramic eye is embedded and fixedly connected inside the slider.

[0007] Preferably, the outer surface of the second screw is threaded with two second positioning nuts. The two second positioning nuts not only facilitate the fixing of the weft yarn stabilizing mechanism, but also facilitate the adjustment of the position of the weft yarn stabilizing mechanism.

[0008] Preferably, the outer surface of the frame has openings on both sides that cooperate with the second ceramic eye, so as to facilitate the normal transmission of the weft yarn.

[0010] Preferably, the outer surface of the first screw rod is threadedly connected with two first positioning nuts, so as to fix and adjust the weft guide mechanism.

[0011] The weft stabilizing device of the ribbon loom has the following beneficial effects:

[0012] The weft stabilizing device of the ribbon loom, through the weft guide mechanism and the weft stabilizing mechanism, the weft passes through the second ceramic eye in the transmission process, due to the gravity of the sliding block, the weft is pressurized to a certain extent, and since the sliding block is slidingly connected in the inner part of the frame body, the tension of the weft can be automatically changed according to the actual situation, the jumping of the weft can be reduced, and the stability of the weft transmission can be improved.
