The specific embodiment
Further specify the present invention below in conjunction with embodiment.
As Fig. 1, shown in Fig. 2 (a) and Fig. 2 (b), a kind of minor air cell 1 that comprises provided by the invention, be passed into the spindle shape doffing tube 2 in the minor air cell 1, the vortex tube 4 that is connected with fixed support 3 and place air flow jetting hole 5 in the vortex tube 4, the center of spindle shape doffing tube 2 is provided with passage 6, it is characterized in that, be provided with truncated cone-shaped or columniform fiber and core silk guiding part 7 in the porch of vortex tube 4, be provided with needle-like core silk guide wire 8 on the top of fiber and core silk guiding part 7, between the inlet 9 of spindle shape doffing tube 2 and needle-like core silk guide wire 8, be provided with the gap x that width is 2mm.Be penetrated with core silk through hole 10 in the described needle-like core silk guide wire 8.
Described fiber and core silk guiding part 7 are made up of fiber spiral-guide face 11 and the core silk guide hole 12 that runs through its center; Described core silk guide hole 12 1 ends are connected with core silk through hole 10.
Be provided with fiber input channel 13 between described fiber spiral-guide face 11 and vortex tube 4 inwalls; Described needle-like core silk guide wire 8 is on the same axis with the inlet 9 of spindle shape doffing tube 2.
The hand of spiral of described fiber spiral-guide face 11 is identical with the direction of vortex tube 4 mesoscale eddies air-flows, and spiral angle is 70 degree.Going up between side cut 13 and the following side cut 14 of described fiber spiral-guide face 11 becomes the 70 angle α that spend.The cross section of described core silk through hole 10 and core silk guide hole (12) is circular.The axis of described core silk guide hole 12 becomes the 0 angle β that spends with the formation fiber with the axis of core silk guiding part 7.
Its operation principle is: 1～2 core silk can be introduced into spinning apparatus by core silk guide hole 12 and needle-like core silk guide wire 2.Because needle-like core silk guide wire 8 is on the same axis with the axis of spindle shape doffing tube 2, and closely points to the inlet 9 of doffing tube, so core silk 15 can be introduced spindle shape doffing tube 2 exactly.The effect that is subjected to vortex tube 4 porch suction airstream through the fibre bundle 16 of drafting system output is inhaled into, and carries smoothly through fiber input channel 13.Because the cross section of fiber input channel 13 is reducing of approximate fixed proportion, and is the level and smooth shape that reverses, so fibre bundle 16 is subjected to the boundling effect in conveying.Fibre bundle 16 is walked around described needle-like core silk guide wire 8 subsequently, and the twist that needle-like core silk guide wire 8 has stoped the downstream to form yarn in this process is uploaded, and is convenient to the separation of fiber in the fibre bundle 16.Enter the fibre bundle that fiber front end in the fibre bundle 16 of minor air cell 1 formed yarn and draw in doffing tube 2, and tail end is separated from fibre bundle 16 owing to the effect that is subjected to rotating vortex, form free end 17, and lodging is rotated with the rotation of eddy current on the spindle shape doffing tube conical surface 18.Because fibre bundle 16 is walked around described needle-like core silk guide wire 8, makes core silk 15 be positioned at the center of fibre bundle 16, the fiber of rotation is twisted looping equably on core silk 15, forms the cladded yarn 19 with real ring-spun feature of twisting with the fingers.The yarn 19 that forms is by passage 6 outputs at doffing tube 2 centers, and the process delivery roller is wound on and forms package on the groove drum.
As shown in Figure 3 and Figure 4, embodiment 2 is that with the difference of embodiment 1 described fiber and core silk guiding part 7 are columniform.Other structures and operation principle thereof are identical with embodiment 1.
