A thread jumping prevention device for spinning, comprising a base (1), and a drawing device and a guiding device provided side by side at an upper end of the base. The drawing device comprises, sequentially and from bottom to top on the base, a support base A(3), a tension spring (4) and a threading apparatus A(5). On the threading apparatus A(5) is provided a through-hole A(6) for a yarn to pass through, two ends of the through-hole A(6) having a curved shape. The guiding device comprises on the base a support base B(9) and a threading apparatus B(7) hinge-connected at an upper end of the support base B(9). On the threading apparatus B(7) is provided a through-hole B(8) for a yarn to pass through, two ends of the through-hole B(8) having a curved shape. The thread jumping prevention device for spinning is mainly composed of the drawing device and guiding device. The drawing device has a tension spring thereon, and thus reduces yarn jumping to a certain extent. The guiding device has a fixed structure, and thus the yarn can be stably transported. When the two are used in cooperation, guiding is accurate and stable. Further, the end of the through-hole of the threading apparatus has a curved shape, preventing yarn breakage. The invention has a reasonable configuration. |
