Description
Technical field
The invention belongs to silk thread processing machinery field more particularly to a kind of folding and unfolding silk device and methods.
Background technique
Silk thread needs to pass through silk when being released from spool for consuming, or finished product silk thread being wound on spool
Line folding and unfolding silk machine operation, current receipts thread supplying machine put that a process is fairly simple, and general direct pull silk thread forces spool to revolve
Turn, silk thread is released, also needs to add damping system on spool sometimes, puts thread tension to keep certain.
It is above-mentioned this simply to put silk since winding path of the silk thread on spool is a complicated space layout process
Method will cause silk thread on the position for being detached from spool surface, not based on draw wire direction and the original winding direction of silk thread
Unanimously, the lateral sliding for causing silk thread is exactly a kind of greatly damage for some silk threads that cannot bear side-friction
Wound, causes silk thread quality to be greatly reduced.For that can only be wound with wiring unit for the silk thread for receiving silk, current receive silk machine master
It is moved back and forth on the direction perpendicular to reel axis with wiring unit traction silk thread, so that silk thread is helically wound around on spool.
To silk thread push-pull effect will necessarily occur for this reciprocating motion for receiving wiring unit in silk method, so that loose when tight when silk thread, wire
Speed and tension are uneven, influence the normal running conditions of silk thread system of processing.
What is be commonly used is the wiring unit of multiple-rotor clamping silk thread formula, by two or more parallel shafts
Between clamp silk thread, the winding position of Lai Dingwei silk thread.But this wiring unit is since shaft diameter is small, so that silk thread is in shaft table
Frictionally damage on face is larger.
