Embodiment Construction

[0036] The invention utilizes the principle of magnetic levitation to realize the non-contact support and positioning of the false twist balloon. Specifically, the horizontal magnets of the upper and lower electromagnetic coils in the false twist unit are energized to generate axial magnetic levitation force to suspend the false twist balloon in the false twist unit, and the shaft is lifted. The vertical magnets of the upper and lower electromagnetic coils in the false twist unit are energized to generate longitudinal magnetic levitation force to keep the gap between the main pole stator and the iron core rotor unchanged;

[0037] At the same time, the present invention also uses the principle of electromagnetic field drive to drive the false twist balloon to rotate at high speed without contact. Specifically, the main magnetic pole stator is energized by the commutation pole to generate a magnetic field to drive the iron core rotor to rotate, and the iron core rotor is fixed ou...

Abstract

The present invention provides a magnetic false-twisting apparatus dedicated for spandex fibers. The apparatus comprises false-twisting units (100), false-twisting rods (200), connecting bolts (300),a cable (400), a commutating pole (500), a rheostat (600) and spandex fibers (700), wherein the multi-group false-twisting units (100) are horizontally fixed on the false-twisting rods (200) along thefalse-twisting rods (200) via the connecting bolts (300), the multi-group false-twisting units (100) are connected with the commutating pole (500) via the cable (400), and rotation speed of false-twisting ballooning in the false-twisting units is adjusted via the rheostat (600). The false-twisting unit moving parts are contactless and wear-free, and have good uniformity, and the defects that foran existing false twister, operation cost is high, uniformity is poor, noise is large and labor intensity is high are overcome.

Description

technical field [0001] The invention relates to the field of false twisting in the spandex fiber spinning section. Specifically, the invention relates to the use of magnetic field force to suspend the false twisting balloon, the main magnetic pole stator electrifies the iron core rotor to drive the false twisting balloon to rotate at high speed, and the air in the false twisting balloon is formed Rotating airflow, a special device for entangling and false twisting two or more strands of spandex fibers into one strand. Background technique [0002] The prior art Chinese patent CN 104711723B discloses a special mechanical false twisting device for spandex elastic fiber, which includes a plurality of through holes arranged side by side along the length direction of the false twister rod, and the ceramic false twister is located in the through holes. Each ceramic false twister and synchronous motor are connected by a synchronous belt, and the synchronous motor is controlled by a...
