[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Example 1

[0030] Please refer to Figures 1-3 This utility model provides a device for steady spinning of high-elongation polyester industrial yarn, including a mounting plate 1, which can be fixed between the fifth roller and the sixth roller. Since a positioning block 2 is provided on one side of the mounting plate 1, and multiple through holes 3 are provided on the positioning block 2, multiple yarn splitting rods 4 are inserted into the through holes 3. The yarn bundles are respectively located between two adjacent yarn splitting rods 4, which ensures steady spinning, avoids yarn breakage, reduces product defect rate, and improves product quality rate.

[0031] Meanwhile, in order to prevent the wire bundle from jumping out of the wire splitting rod 4, two sets of limiting blocks 5 are provided on the mounting plate 1 near the other side. Multiple insertion holes 6 are opened at the upper end of the limiting block 5, and a stop bar 7 is inserted into the insertion hole 6. After the wire bundle is limited by the two stop bars 7, it passes through multiple wire splitting rods 4. The stop bar 7 is used to limit the wire bundle.

[0032] Among them, two stop rods 7 are interlocked on the upper ends of two limit blocks 5. The interlocked stop rods 7 can better restrict the position of the filament bundle, prevent the filament bundle from shifting or jumping out of the filament splitter 4 during the spinning process, and at the same time make the filament bundle more evenly distributed when passing through the filament splitter 4, thereby improving the uniformity and consistency of spinning.

[0033] The two limit blocks 5 have different lengths, which allows the two stop bars 7 to be installed in an alternating manner.

[0034] In addition, the lateral length of the wire splitting rod 4 is greater than the length of the limiting block 5, further preventing the wire bundle from jumping out of the wire splitting rod 4.

[0035] Example 2

[0036] like Figures 5 to 8 As shown, a fixing sleeve 8 is fixed to the rear side of the positioning block 2 by a thread. A sliding groove 9 is provided at the bottom of the fixing sleeve 8. A fixing plate 10 is slidably arranged in the sliding groove 9. Arc groove 2 12 and arc groove 11 are respectively provided on the inner side of the fixing plate 10 and the fixing sleeve 8. The tail end of the dividing screw 4 is located in the arc groove 11 and arc groove 2 12. The dividing screw 4 is fixed by the fixing sleeve 8 and the fixing plate 10, which improves the stability of the dividing screw 4 during use.

[0037] Furthermore, a screw 14 is threadedly connected to one side of the fixed sleeve 8. The screw 14 passes through the fixed sleeve 8 and is rotatably connected to the fixed plate 10. By rotating the screw 14, the fixed plate 10 is slid in the slide groove 9, so that the fixed plate 10 can move closer to or away from the lead screw 4.

[0038] Elastic pads 13 are symmetrically arranged inside the arc groove 12. When the fixing plate 10 fixes the lead screw 4, the elastic pads 13 contact the lead screw 4, which not only improves the fixing effect, but also avoids damage to the lead screw 4.

[0039] In addition, multiple through holes 16 are provided on the side walls of the two limiting blocks 5. The through holes 16 are connected to the corresponding insertion holes 6. The bottom of the stop rod 7 is provided with a slot 15. When the stop rod 7 is inserted into the insertion hole 6, the positioning rod 17 is inserted from the corresponding through hole 16 into the slot 15 of the insertion hole 6 to fix the stop rod 7 and improve the stability of the stop rod 7 during use.

[0040] Example 3

[0041] like Figure 4 As shown, when it is necessary to disassemble the lead screw 4, the bolts of the fixing sleeve 8 can be removed, and by moving the fixing sleeve 8 outward, the fixing sleeve 8 can move together with multiple lead screws 4, so as to achieve the purpose of disassembling multiple lead screws 4 at the same time.

[0042] In summary, the working principle of the device for steady spinning of high-elongation polyester industrial yarn according to the present invention is as follows: the mounting plate 1 is fixed between the rollers, and the yarn bundle is restricted by two baffles 7, so that the yarn bundle can be stably separated by the yarn splitting rod 4, preventing the yarn bundle from jumping out of the yarn splitting rod 4, and minimizing the number of yarn breakages.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
