At present, false twist texturing machines all process fibers by multiple spindle numbers, and one machine consists of tens of spindle numbers to hundreds of spindle numbers. The size space between the spindle positions is called spindle space, the spindle space is an important parameter of the false twist texturing machine, and the space of the threading mechanism is matched with the spindle space of the machine. In a general double-wire false twisting deformation machine, left and right wires enter a wire guiding mechanism at the same time, one wire guiding mechanism is used for guiding the wires, and finally the left and right wires are combined into a twisted fiber to be wound into a product, and the space between the wire guiding mechanisms of the double-wire false twisting deformation machine is matched with the spindle space of the double-wire false twisting deformation machine.
Existing manual wire guiding mechanisms or wire guiding mechanisms adopt a single-wire-channel wire guiding mechanism according to the machine type, as shown in fig. 3, or a double-wire-channel wire guiding mechanism. One fiber is led by each yarn leading mechanism to be a single yarn leading mechanism, and two fibers can be led by each yarn leading mechanism simultaneously to be a double yarn leading mechanism. One side of the sliding sleeve in the yarn guiding mechanism is connected with a rotary yarn guiding arm, namely the rotary yarn guiding arm is in an external form relative to the sliding sleeve, and the transverse size of the rotary yarn guiding arm cannot be reduced due to structural limitation, so that the spindle torque of a machine cannot be reduced, and the spindle torque of the yarn guiding mechanism in the prior art is basically more than 100 mm.
