Description
Technical field
The present invention relates to a kind of negative pressure threading yarn pipe.
Background technology
The flyer bobbin that in prior art, automatic doffing roving frame uses, its repiece principle is all identical, namely adopts and wraps up one deck suede band on flyer bobbin top or bottom, when starting to spin, allowing yarn be pasted onto on suede band, reaching the object of repiece.The repiece rate of rove reaches and is only about 80%, also needs human assistance repiece, increases the work capacity of rove spinner, is mainly manifested in following two aspects:
One is the flyer bobbin used at present, when repiece by the impact of flyer presser position, when the pressing device position that starts to spin does not arrive bobbin suede band position, yarn can not contact with suede band, yarn can gather around head at fly frame scroll tube with upper part, cause the phenomenon that rove repiece rate is not high, be not well positioned to meet the requirement of the automatic repiece of rove.
Two be the flyer bobbin that uses at present in use for some time, suede band can adhere to one deck fiber, even produce a large amount of electrostatic, the adhesive force of suede band can weaken, when causing repiece, yarn can not be attached on spool, affect automatic repiece rate, cause the phenomenon needing rove spinner human assistance repiece, be not well positioned to meet the requirement of automatic repiece.
From above-mentioned, current existing spool structure has determined the requirement that it is not well positioned to meet the automatic repiece of automatic doffing roving frame, awaits improving further and developing.
Summary of the invention
