Filament POY (Pre-Oriented Yarn) drafting and winding device

Abstract

Disclosed is an apparatus for drawing and winding POY filament yarn. The drawing and winding apparatus comprises: a yarn cutting and suctioning apparatus, a pre-interlacing device, a first yarn guide plate, a second yarn guide plate, a lifting mechanism, a lifting seat, a machine frame and a winder, wherein the yarn cutting and suctioning apparatus, the pre-interlacing device and the first yarn guide plate are provided in succession on one side of the machine frame based on the direction of travel of a tow; the lifting mechanism is provided on the machine frame, the lifting seat is linked to the lifting mechanism, and the lifting seat makes a reciprocal movement in a vertical direction under the drive of the lifting mechanism; the second yarn guide plates are two in number and are provided horizontally on the lifting seat; the winder is provided below the second yarn guide plates; after passing through the yarn cutting and suctioning apparatus, the pre-interlacing device and the first yarn guide plate, the tow is divided into two bundles respectively reeled on the two second yarn guide plates and then entering the winder to be wound. The present invention simplifies the structure and also increases the quality of the yarn, and enables more spinning station equipment to be installed in the same factory, increasing production capacity and reducing engineering construction costs.

Description

technical field [0001] The invention relates to the technical field of chemical fiber machinery manufacturing, in particular to a POY filament drafting and winding device. Background technique [0002] In the traditional spinning system, the two units of drafting and winding are separated by a steel platform in the drafting and winding device to form upper and lower levels. The threading operation is carried out by the upper and lower operators respectively. Long, waste silk and prone to operational errors. Moreover, this device occupies a large area, and the height of the required factory building is high, which is a great waste of infrastructure projects. Therefore, when the profits of chemical fiber spinning equipment are getting weaker and weaker, seeking a drafting and winding device with simpler structure, simpler operation and lower energy consumption has become the direction that chemical fiber machinery manufacturers are striving to overcome.
