Double-yarn guide device of winding machine

Abstract

The invention particularly relates to a double-yarn guide device of a winding machine. The double-yarn guide device comprises a first reciprocating yarn guide device and a second reciprocating yarn guide device, the first reciprocating yarn guide device comprises a first reciprocating mechanism and a first yarn guide mechanism, and the first yarn guide mechanism is fixedly connected to the first reciprocating mechanism through a first sliding block connecting piece; the second reciprocating yarn guide device comprises a second reciprocating mechanism and a second yarn guide mechanism, and the second yarn guide mechanism is fixedly connected to the second reciprocating mechanism through a second sliding block connecting piece; and fibers are led in through a yarn guide wheel, sequentially pass through the first yarn guide mechanism and the second yarn guide mechanism and are wound on a spindle of the winding machine, and the first reciprocating yarn guide device and the second reciprocating yarn guide device are controlled through a controller and achieve synchronous reciprocating motion. The first reciprocating yarn guide device and the second reciprocating yarn guide device are controlled through the controller and achieve synchronous reciprocating motion, the angle of reciprocating swinging of the fibers driven by the reciprocating yarn guide devices is reduced, and yarn rubbing and yarn damage are avoided.

Description

Technical field[0001]The present invention relates to the technical field of fiber windows, and more particularly to a wounder dual guide wire device.Background technique[0002]High-performance carbon fiber light, and has high strength, high modulus, high temperature resistance, corrosion resistance, anti-brush, sputtering, and other excellent performance, and has good designs and composite, which is built rocket, satellite, missile. , Fighters, ships such as fighters, ships, etc. must be indispensable. With the advancement of technology, carbon fiber is getting wider and wider, in order to meet the needs of civilian markets and reduce production costs, carbon fibers in civil fields are increasingly developed in a wide wire direction, and the carbon fibers of 48K and above are. The direction of current focus development. The carbon fiber itself has a soft and brittle feature, and the 48K yarn is composed of 48,000 thin fibers. Although there is a very strong pull-off force in the lon...

Problems solved by technology

[0003] The winding machine in the prior art has only one reciprocating wire guide device, and no matter what changes it makes for different fibers (tows), it is impossible to change the angle α at which the reciprocating wire guide device drives the fiber to swing back and forth is too large, because Restricted by various aspects and the height of its own design, it is impossible to reduce α, which makes the horizontal friction of the fiber on the yarn feeding wheel and the yarn guide of the reciprocating yarn guide device large, and the tension change also increases accordingly, which is prone to rubbing and yarn wide variation, such as Figure 5 shown

In addition, when the fiber is reciprocating, it swings back and forth at the wire feeding wheel, which makes the fiber prone to "scratch" at the wire feeding wheel, which affects the quality of the fiber
