4. The yarn feeder of claim 2 wherein: A fixing assembly (6) for assisting the compression of the auxiliary receiving roller (31) is installed at the top of the second receiving block (5), the fixing assembly (6) comprises a lead screw (8) penetratingly installed on the second receiving block (5), the second receiving block (5) is in threaded cooperation with the lead screw (8), and a compression plate (7) is embedded and installed at the bottom of the lead screw (8).
5. A method of using a loom thread unwinding mechanism, using the loom thread unwinding mechanism of claim 4, characterized in that, The method comprises the following steps: S1, the receiving roller (31) is overlapped and installed on the first receiving block (4), the screw rod (8) is rotated, the second receiving block (5) is threadedly connected with the screw rod (8), so that the screw rod (8) is lowered as a whole, the pressing plate (7) is lowered in the process of the screw rod (8) being lowered, and then the pressing plate (7) is slightly pressed on the receiving roller (31), so that the whole receiving and pressing treatment of the pay-off roller (3) is completed; S2, the yarn (2) on the pay-off roller (3) is sequentially threaded through the guide rod (9), the guide rod (131), the threading hole (141), and the guide wheel (151) and the guide rod (9). In work, the yarn (2) has a certain tightness, thereby driving the guide rod (131) to be lifted, and the pressing plate (15) is tilted and opened under the action of the movement of the yarn (2); S3, according to the different overall strength of the yarn (2), the overall tension tightness of the yarn (2) is adjusted in advance, the second rotating rod (203) is reversed, the second rotating rod (203) drives the adjusting rod (202) to rotate as a whole, the positioning column (201) is threadedly connected with the adjusting rod (202), so that one end of the adjusting rod (202) is pulled out from the positioning hole as a whole, at this time the first rotating rod (191) is rotated, the first rotating rod (191) drives the adjusting roller (19) to rotate as a whole, the connecting rope (18) is wound around the outer edge of the adjusting roller (19) in the process of the adjusting roller (19) rotating, so that the top plate (1521) and the pushing block (1321) are pulled, and the second pressing spring (1525) and the first pressing spring (1323) are compressed and shortened, thereby the pressure of the pushing sleeve (1522) and the protruding block (1324) is improved, so that the overall tension tightness of the yarn (2) is effectively adjusted, and the pressure of the guide rod (131) on the yarn (2) and the tension of the guide wheel (151) on the yarn (2) are adjusted, thereby the yarn (2) is adjusted to a certain tension, thereby adapting to different working requirements, after the adjusting roller (19) is adjusted, the second rotating rod (203) is rotated in the positive direction, thereby the adjusting rod (202) is inserted and installed in the positioning hole, so that the overall positioning treatment of the position of the adjusting roller (19) is completed; S4, after the yarn (2) breaks, the sliding sleeve (1522) is pushed and drives the supporting rod (1523) to be pulled under the action of the second pressing spring (1525) and the first pressing spring (1323), thereby the protruding plate (14) and the pressing plate (15) are closed as a whole to preliminarily clamp the yarn (2), at the same time the first pressing spring (1323) pushes the protruding block (1324) to push and make the guide rod (131) on the guide disc (13) press on the protruding plate (121), so that the secondary clamping treatment of the yarn (2) is completed, which can effectively avoid the loosening of the yarn (2) after breaking and the winding with other yarns (2).
