Constant-tension zero-twist fiber unfolding and winding device and operation method thereof

Abstract

The invention relates to a constant-tension zero-twist fiber unfolding and winding device. An active unwinding device, a yarn guiding and buffering device, a zero-twist fiber unfolding device, a winding device and a reciprocating device are included. The active unwinding device conducts unwinding operation on yarn on a spool. The yarn guiding and buffering device conducts the guiding movement on the yarn and provides buffering power, and the yarn is prevented from being snapped. The zero-twist fiber unfolding device conducts guiding and fiber unfolding operation on the yarn. The winding devicewinds the yarn obtained after fiber unfolding. The reciprocating device drives the zero-twist fiber unfolding device to reciprocate. The active unwinding device and the yarn guiding and buffering device are connected, the zero-twist fiber unfolding device is connected with the yarn guiding and buffering device and loaded on the end face of the reciprocating device, and the winding device is connected with the zero-twist fiber unfolding device. By means of the constant-tension zero-twist fiber unfolding and winding device, yarn unwinding, fiber unfolding and winding are finished in one device,and practicability and work efficiency of the constant-tension zero-twist fiber unfolding and winding device are improved. Meanwhile, the invention further relates to an operation method of the constant-tension zero-twist fiber unfolding and winding device.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a constant tension non-twist fiber spreading and winding device and an operating method thereof. Background technique [0002] During the processing and reproduction of yarn (including carbon fiber, glass fiber and other yarns), it is necessary to unwind, guide, spread, collect and reprocess the yarn, and pass the raw material wound on the reel through the yarn guide buffer device The fiber spreading device is introduced to spread the yarn, and then the yarn is wound up by the winding device. The structure of the existing device is complicated, and it is impossible to unwind, guide, spread and collect the yarn at the same time. Moreover, the existing yarn guide device is usually a porcelain eye guide, and the yarn is collected by a porcelain eye plate. The yarn is easily broken due to the obstruction around the porcelain eye. The axial vibration of the fiber spreading roller is ...

The structure of the existing device is complicated, and it is impossible to unwind, guide, spread and collect the yarn at the same time

Moreover, the existing yarn guide device is usually a porcelain eye guide, and the yarn is collected by a porcelain eye plate. The yarn is easily broken due to the obstruction around the porcelain eye. The axial vibration of the fiber spreading roller is used to spread the fiber together. This method is easy to make the yarn rotate during the yarn guiding process; the existing winding device generally uses a winding roller for winding, and most of the structures are relatively complicated, and it is difficult to replace the winding roller
