Problems solved by technology

However, when the mandrel has a plate-shaped structure, due to the structural difference between the plate-shaped mandrel and the cylindrical mandrel, when the spread yarn is wound with the plate-shaped mandrel, the yarn wound on the plate-shaped mandrel The linear speed is not uniform, and the tension of the yarn is difficult to control

Embodiment 1

[0039] like Figure 1 to 2 FIG flat carbon fiber yarn is wound with constant tension yarn storage device, comprising:

[0040] Unwinding apparatus 1, the yarn on the bobbin unwinding constant speed operation;

[0041] Exhibition fiber means 2, the yarn fineness development operation;

[0042] Tension detecting means 3 detects yarn tension;

[0043] Receiving winding means for winding the yarn further comprising a yarn winding plate 4 and the drive motor 5, the yarn winding plate 4 is rotated at constant speed drive motor 5 is driven to show the completed fiber yarn wound closed;

[0044] Wherein the developing means and the receiving means fibers between about 2 further provided with an automatic yarn storage device, the automatic yarn storage device for real-time compensation of yarn unwinding discharge apparatus 1 and the amount of the difference between the amount of yarn wound strand receiving plate 4, thereby the yarn is kept constant, the automatic yarn storage device by mean...

Embodiment 2

[0053] The present invention also discloses a constant tension storage yarn control method for flat winding carbon fiber yarn.

[0054] S1: A constant speed flacker is performed on the yarn cylinder using the shaken device 1, and the yarn on the yarn is sequentially wrapped over the screen 4 after the yarn is passed through the extension device 2 and the automatic storage yarn device;

[0055] S2: Set the tapping angle velocity around the yarn plate 4 to rotate 180 ° around the yarn plate 4 is one cycle, calculate the real-time grating amount wound around the yarn plate 4;

[0056] S2: Turn 180 ° in the yarn plate 4 is one cycle, calculate the real-time gaute amount of the discharge device 1, and find the spin angle velocity of the discharge device 1;

[0057] S3: By calculating the difference between the real-time gaute and the real-time spinning amount, the real-time compensation amount of the automatic storage unit is calculated, and the automatic storage unit is set to the aut...

Abstract

The invention relates to the technical field of yarn storage, in particular to a constant-tension yarn storage device for flat plate winding of carbon fiber yarn and a control method. The device comprises an unwinding device for unwinding the yarn on a spool at a constant speed; a fiber spreading device for carrying out fiber spreading operation on the yarn; a tension detection device for detecting the tension of the yarn; and a winding device which further comprises a yarn winding plate for winding the yarn and a driving motor, wherein the yarn winding plate is driven by the driving motor to rotate at a constant speed so as to wind the yarn obtained after fiber spreading. An automatic yarn storage device is further arranged between the winding device and the fiber spreading device and used for compensating for the difference value between the yarn unwinding amount of the unwinding device and the yarn winding amount of the yarn winding plate in real time, so that the speed and tension of the yarn passing through the fiber spreading device are kept constant, the product quality is improved, and the practicability is achieved.

Description

Technical field [0001] Technical Field The present invention relates to a yarn storage, in particular, it relates to constant tension yarn storage device and a control method of a flat carbon fiber yarn by winding. Background technique [0002] Refers to the carbon filament winding carbon fiber prepreg is wound onto a mandrel according to certain rules, and after curing, demolding the article is obtained. These include wet winding, i.e., the carbon fiber prepreg is wound under tension directly to the control mandrel, winding tension so that the excess air bubble is extruded, molded carbon fiber winding is wound according to the design rule of the product can be forced state, full strength of the fiber , its cost is relatively low and the products air tightness, easily mechanized and automated production. [0003] In the prior art, multi-core die to a cylindrical structure, the carbon fiber which is wound on tension control is relatively easy, as long as the constant speed control...
