Description
Technical field
The invention belongs to ring spun yarn equipment technical field, particularly the structural design of the anti-lock grooving apparatus of a kind of ring spun yarn pipe.
Background technology
In the process of ring spun yarn, need the spool having spun yarn (being called full spool or cop) to take off from the spindle of fine spining machine, this link is called doffs.The mode of doffing of current ring spinning frame is divided into two large classes, and a class is manually doffed---and with hand, spool is put into yarn basket by people after spindle blade is chosen, and will the empty spool of yarn do not had to put on spindle blade; Another kind of is that machine doffs, come one by one with doffer or small lot take off spool, adopt Intubaction device to put on spindle blade by empty spool, some fine spining machines carry integral cosine doffing device, utilize its collective doffing mechanism to doff in large quantity and intubate work simultaneously simultaneously.
Spool is needed to fit tightly spindle blade during Spinning Frame spun yarn, the such rotating speed of spool and spindle blade of could allowing is consistent, spindle blade follows the main CD-ROM drive motor high speed rotating (being generally several thousand turns per minute, even up to ten thousand turns) of fine spining machine under the transmission of driving belt.Fine spining machine is divided into two large classes, and a class adopts light spindle blade, and a class adopts aluminium loop bar.Aluminium loop bar can reach spool and the fitting tightly of spindle blade when spindle blade rotates owing to there being spring centrifugal globe device, and less being convenient to of frictional force when spindle blade does not turn between spool and spindle blade is taken off, and therefore, the fine spining machine with integral cosine doffing device all adopts aluminium loop bar.But the device of aluminium loop bar is complicated, and cost is higher, the fine spining machine existing market occupancy volume with collective doffing is less.
Most fine spining machines adopt the light spindle blade of low cost; but there is a difficult problem of pulling out yarn difficulty in light spindle blade: in order to ensure effective laminating of spool and light spindle blade; the endoporus (i.e. the endoporus of spool inner core) of spool has certain Small Taper; the tapering of itself and light spindle blade coincide and better forms closely cooperating of the self-locking conical surface; spinning effect is better; but; part spool Chang Huiyu spindle blade laminating tension and produce local subatmospheric sealing area, cause atmospheric pressure hinder choosing for spool.Especially more easily there is such problem in the spool of Long-Time Service, when the dirt wadding sealing of Long-Time Service and spinning, High Rotation Speed agrees with, these combined factors cause the airtight phenomenon in local between spool inner core and spindle blade, in order to the spool taking off laminating tension often need spend more manpowers and time, labour intensity is excessive, waste time and energy, sometimes manually spool of choosing is difficult to, even do not stint and destroy spool and spindle blade itself, affect spinning efficiency, increase spinning cost, also often need to change spool or maintenance spindle blade.
Summary of the invention
