The untwisted fiber spreading device 3 is detachably arranged on the sliding plate 52, the sliding plate 52 drives the untwisted fiber spreading device 3 to reciprocate on the guide rail 51, and the yarn after fiber spreading is recovered and wound on the yarn winding plate 42 of the winding device 4; in the process of rotating and winding the yarns on the winding plate 42, the distance between the yarns on the winding plate 42 needs to be adjusted, so that no gaps exist among the yarns, and uneven winding can be caused when the gaps are too large or too small, the PLC 53 is used for matching the rotating speed ratio of the winding motor 46 to control the reciprocating speed of the reciprocating motion device 5, so that no gaps exist among the yarns wound on the winding plate 42, the winding of the yarns with various fiber spreading widths is realized, the gapless winding of the yarns is realized, the smooth winding plate 42 of the winding is further realized, and the subsequent operation is convenient.

Reciprocating motion device 5 adopts linear module to realize winding the required reciprocal linear motion of yarn board 42, avoids adopting traditional reciprocal lead screw structure and the stroke that arouses is not adjustable, the utility model discloses well reciprocating motion device compact structure and reciprocal stroke are adjustable. The master control box 7 is arranged on the reciprocating motion device 5 and controls the operation of the untwisted fiber spreading and winding device.

An operation method of a constant-tension untwisted fiber winding device comprises the following specific steps:

the method comprises the following steps: a bobbin is placed on an air expansion shaft 14 of the active unwinding device 1;

step two: the winding plate 42 of the winding device 4 is wrapped by the demoulding cloth and the flow guide net and is fixedly arranged between the two fixing frames 41;

step three: finding out the end part of the yarn on the bobbin, firstly, the wrap angle penetrates through a first yarn guide roller 24 of the yarn guide buffer device 2, then penetrates through a second yarn guide roller 31 of the twistless fiber spreading device 3, further sequentially penetrates through each fiber spreading roller 32 in an up-and-down wrap angle mode, and finally, the end part of the yarn is fixed at the end part of a yarn winding plate 42 of the winding device 4;

step four: switching on a power supply, starting a master control switch of the control box 7, enabling the active unwinding device 1, the yarn guide buffer device 2, the untwisted fiber unfolding device 3, the winding device 4 and the reciprocating device 5 to work together, realizing unwinding, fiber unfolding and winding of yarns, and winding the yarns after final fiber unfolding on the yarn winding plate 42 layer by layer;

step five: and (3) after the yarn spreading and fiber winding are finished, closing the master control switch and taking out the winding plate 42 which finishes the yarn winding on the winding device 4.

If the mechanical test needs to be carried out on the yarn which is not finished by fiber spreading, the yarn winding plate 42 which is taken out after the yarn winding is finished is wrapped with the flow guide net and the demolding cloth, vacuum infusion is carried out, a required sample strip is cut, and finally, various mechanical tests are carried out on the sample strip.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
