US 9,347,150 B2 · Filament positioning control device for composite spinning of filaments and staple fibers

Abstract

A filament positioning control device for composite spinning of filaments and staple fibers comprises a fixed shaft and a hollow shaft mounted thereon. Left and right spiral wheels with left and right spiral grooves are mounted on the hollow shaft. Left and right positioning plates are provided on outer sides of left and right spiral wheels, each having a guide pin engaged in a spiral groove. Each positioning plate has a guide block engaged in a guide rail. As the hollow shaft is rotated, the spiral wheels rotate accordingly and the guide pins on the left and right positioning wheels move along with the spiral grooves. Because spiral grooves on two spiral wheels have different directions, when the spiral wheels rotate, the distance between positioning grooves on the two positioning plates increases or decreases, thereby changing the distance between two filaments guided by grooves on the positioning plates.

Dependent claims

A method for adjusting a distance between a first positioning plate and a second positioning plate in a filament positioning control device, said method comprising:

providing a first guide pin on the first positioning plate and a second guide pin on the second positioning plate;
providing a first spiral wheel comprising a first spiral groove and a second spiral wheel comprising a second spiral groove;
engaging the first guide pin in the first spiral groove and the second guide pin in the second spiral groove, the first and second spiral wheels arranged for simultaneous rotation about a shaft in a first direction or an opposing second direction, wherein when the first and second spiral wheels are rotated in the first direction, the first and second spiral grooves cause the first and second positioning plates to move towards each other, and when the first and second spiral wheels are rotated in the second direction, the first and second spiral grooves cause the first and second positioning plates to move away from each other, wherein each of the first and second positioning plates comprises a positioning groove configured to position a filament for spinning.

A filament positioning control device for use in composite spinning of filaments and staple fibers, comprising:

a first spiral wheel comprising a first spiral groove;
a second spiral wheel comprising a second spiral groove;
a first positioning plate comprising a first guide pin arranged for engagement in the first spiral groove;
a second position plate comprising a second guide pin arranged for engagement in the second spiral groove, wherein the first spiral wheel and the second spiral wheel are arranged for simultaneous rotation about a shaft in a first direction or in an opposing second direction such that when the first and second spiral wheels are caused to rotate in the first direction, the engagement of the first guide pin in the first spiral groove and the engagement of the second guide pin in the second spiral groove cause the first and second positioning plates to move towards each other, and when the first and second spiral wheels are caused to rotate in the second direction, the engagement of the first guide pin in the first spiral groove (18) and the engagement of the second guide pin in the second spiral groove cause the first and second positioning plates to move away from each other, wherein each of the first and second positioning plates comprises a position groove configured to position a filament for spinning.
