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 following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

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

[0044] The unwinding device 1 is used to unwind the yarn with constant tension on the yarn bobbin. The unwinding device 1 further includes a bobbin driver 11, a swing bar 12 and a yarn storage rod 13; the bobbin driver 11 fixes the bobbin to the It drives the yarn bobbin to rotate at a constant speed; one end of the swing arm of the pendulum 12 is rotated, and the other end of the swing arm is provided with a rotating shaft along the axial direction of the yarn bobbin, and the yarn wrapped from the yarn bobbin is wrapped around the rotating shaft to be arranged; There are at least two y...

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 onto the mandrel according to certain rules, and then curing and demolding to obtain products. These include wet winding, that is, carbon fiber prepreg is directly wound onto the mandrel under tension control, and the winding tension makes excess air bubbles squeezed out. Carbon fiber winding molding can design the winding law according to the stress of the product to give full play to the strength of the fiber. , its cost is relatively low and the products produced have good airtightness, which is easy to realize mechanized and automated production. [0003] In the prior art, the core mold is mostly a cylindrical structure, such as a carbon fiber ring forming tool disclosed in the Chinese utility model patent with the publi...
