Problems solved by technology

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

Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] Such as Figure 2-3 The yarn winding system shown includes:

[0044] The unwinding device 1 is used to unwind the yarn on the bobbin under constant tension. The unwinding device 1 further includes a bobbin driving member 11, a swing rod 12 and a yarn storage rod 13. The bobbin driving member 11 fixes the yarn bobbin to It drives the yarn drum to rotate at a uniform speed; one end of the swing arm of the swing rod 12 is set to rotate, and the other end of the swing arm is provided with a rotating shaft along the axial direction of the yarn drum, and the yarn package released from the yarn drum is set around the rotating shaft; At least...

Abstract

The invention relates to the technical field of carbon fiber spreading, in particular to a yarn winding system. The yarn winding system comprises an unwinding device, a yarn translation device and a flat plate winding device, wherein the unwinding device is used for unwinding yarns on a yarn barrel under constant tension; the yarn translation device is used for changing the positions of the yarnsreleased from the unwinding device in the direction perpendicular to the conveying direction of the yarns; and the flat plate winding device is used for winding and forming the yarns; a weight is hungbetween two yarn storage rods, and the yarn tension is ensured to be constant while yarn storage is carried out by using the weight of the weight, so that the problem that the yarn tension is not constant due to the fact that a core mold is plate-shaped and the yarn tension is not constant is solved, and the yarns uniformly wind the plate-type core mold. Meanwhile, the invention further relates to a yarn winding control method. According to the control method, the moving speed of a yarn guide part and the rotating speed of the plate-type core mold are reasonably set, so that the uniform and seamless winding of the yarns on the plate-type core mold is realized, and the mechanical property of a finally-formed carbon fiber product is good.

Description

Technical field [0001] The invention relates to the technical field of carbon fiber spreading, in particular to a yarn winding system and a control method. Background technique [0002] Carbon fiber winding molding refers to winding carbon fiber prepreg on a core mold according to a certain rule, and then curing and demolding to obtain products. Including wet winding, that is, the carbon fiber prepreg is directly wound on the core mold under tension control. The winding tension causes the excess air bubbles to be squeezed out. The carbon fiber winding molding can design the winding law according to the force of the product, and give full play to the strength of the fiber. , Its cost is relatively low and the products produced are airtight, easy to realize mechanized and automated production. [0003] In the prior art, the core mold is mostly cylindrical, such as a carbon fiber ring molding tool disclosed in the Chinese Utility Model Patent Publication No. CN203046242U, such as fig...
