Description
Technical field
The invention belongs to chopped fiber two-for-one twisting machine field, be specifically related to a kind of pneumatic entry spindle.
Background technology
Two-for-one twister is a kind of spinning equipment of one yarn that two strands or multi-strand yarns are become after high efficiency twisting, needs pitch of the laps that yarn is shuttled back and forth in twisting region before twisting, realizes an object that turns two sth. made by twisting.Machine and the broken yarn joint work of all will entrying on new yarn, the maximum link of the amount of labour used that two-for-one twister is produced the at present link of entrying exactly, accounts for greatly 70% of the two-for-one twister amount of labour used.Entry is will be by soft yarn through very long very narrow yarn path, empty-handed operation can not complete, the unique method of prior art adopts the rope of entrying to entry exactly, but use the rope step of entrying comparatively complicated, and time and effort consuming, do not met completely and reduced now the amount of labour used, the development trend of enhancing productivity.
Summary of the invention
The invention solves an above-mentioned difficult problem, a kind of simple in structure, easy to operate, pneumatic entry spindle that efficiency is high is provided.
Technical scheme of the present invention is to provide a kind of pneumatic entry spindle, it comprises pneumatic spindle and switch valve, it is characterized in that: described spindle inside is provided with air-flow reversal chamber, Compressed Gas inlet hole, yarn bullport, yarn outlet hole, described air-flow reversal chamber is tightly connected with described Compressed Gas inlet hole, described yarn bullport, described yarn outlet hole respectively, and one of described Compressed Gas inlet hole limits distance with described switch valve and separates.
Preferably, described switch valve is provided with switch and the valve that can regulate length.
Preferably, oblique described air-flow reversal chamber one side of described Compressed Gas inlet hole passes into air-flow reversal chamber from below.
Preferably, described yarn bullport in the middle of described air-flow reversal chamber from above pass into air-flow reversal chamber.
Preferably, described yarn outlet hole passes into air-flow reversal chamber from the side in described air-flow reversal chamber one side.
Preferably, described Compressed Gas inlet hole passes into air-flow reversal chamber one side and yarn outlet hole to pass into air-flow reversal chamber one side is symmetric position relation in air-flow reversal chamber.
Preferably, past the tilting of described yarn outlet hole along continuous straight runs from air-flow reversal chamber is drawn.
Preferably, one of described Compressed Gas inlet hole is 0.3-1.0mm with described switch valve valve restriction distance.
Pneumatic entry spindle of the present invention can be entried fast under the condition without any need for aid, by production process, operate two-for-one twister the most the operation of complicated and time consumption simplify greatly.That the present invention has is easy to operate, time saving and energy saving, do not need the advantages such as aid.
Accompanying drawing explanation
Fig. 1 is a kind of pneumatic entry spindle structure of most preferred embodiment of the present invention schematic diagram;
Fig. 2 is a kind of pneumatic entry spindle of most preferred embodiment of the present invention gas circuit principle schematic diagram.
Wherein: 1. spindle, 2. switch valve, 3. air-flow reversal chamber, 4. Compressed Gas inlet hole, 5. yarn bullport, 6. yarn outlet hole, 7. switch, 8. valve, 9. yarn.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of pneumatic entry spindle of the present invention, comprise pneumatic spindle (1) and switch valve (2), wherein pneumatic spindle (1) bosom is provided with described air-flow reversal chamber (3), Compressed Gas inlet hole (4) is the amesiality described air-flow reversal chamber (3) that passes into from below, yarn bullport (5) passes into described air-flow reversal chamber (3) from center, top, yarn outlet hole (6) from the side side passes into described air-flow reversal chamber (3).
Compressed Gas inlet hole (4) passes into a side and yarn outlet hole (6), and to pass into a side be symmetric position.
Past the tilting of yarn outlet hole (6) along continuous straight runs from described air-flow reversal chamber (3) is drawn.
As shown in Figure 2, when the present invention works, the switch (7) of opening switch valve (2), compressed air flows at a high speed air-flow reversal chamber (3) along oblique Compressed Gas inlet hole (4), when compressed air hits air-flow reversal chamber (3) one rear flank, turn to the yarn outlet hole (6) of opposite side to flow out at a high speed, now in air-flow reversal chamber (3), form by Compressed Gas inlet hole (4) one effluents the directed high velocity air to yarn outlet hole (6) one sides.
From bernoulli principle: the local air pressure that gas flow rate is large is little, otherwise the little local air pressure of gas flow rate is large.
When the directed high velocity air in said flow reversal chamber (3) is flowed through yarn bullport (5) aperture, the air pressure of the directed high velocity air in described air-flow reversal chamber (3) is little, air pressure in yarn bullport (5) is large, and the air in the yarn bullport (5) that air pressure is large thus flow in the described air-flow reversal chamber (3) that air pressure is little.
In yarn bullport (5), form in summary the windstream flowing in described air-flow reversal chamber (3), and in described air-flow reversal chamber (3), collaborate to flow out from yarn outlet hole (6) with the air-flow that Compressed Gas inlet hole (4) flows into.Now yarn (9) is put into yarn bullport (5) collar extension, under the traction of windstream, through yarn bullport (5), described air-flow reversal chamber (3), yarn outlet hole (6), passes pneumatic spindle (1) and complete the operation of entrying successively.
Yarn outlet hole (6) is obliquely installed obliquely can be so that yarn (9) moves under the drive of high velocity air above pneumatic entry spindle, and handled easily personnel seize yarn and thread head.
Finish the work of entrying, closing switch valve (2) switch (7), stops Compressed Gas and feeds; Valve (8) is provided with (4) one of Compressed Gas inlet holes the gap that limits distance (0.3-1.0mm), making partly to flow into Compressed Gas inlet hole (4) another part from the compressed air of valve ejection misses from gap, switch valve (2) valve (8) can regulate length, in the situation that can not regulating compression pressure, the length that regulates valve (8), can regulate the Compressed Gas air inflow that sprays into Compressed Gas inlet hole (4).
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
