Silk guide device of rolling-up device

Abstract

A yarn guiding device of a winding machine is provided to improve properties of yarns as the tension of the yarn by adopting an over feed roller, initially contacting the yarn to the over feed roller, and guiding the yarns to a friction roller and a bobbin and to induce the various properties of the yarns by properly regulating speed of the over feed roller. A yarn guiding device(100) of a winding machine is composed of a body(10) positioned to the upper part of a bobbin winding yarns at high speed, formed in an almost square shape, and arranged with a round part(12) recessed inward near the bobbin at the lower part; a friction roller(20) combined to the round part of the body and contacted to the bobbin in winding yarns at high speed to rotate in the opposite direction; and an over feed roller(30) combined to the round part of the body, separated from the friction roller and the bobbin at a constant distance, contacted with the constant length of the yarn, and rotated with guiding the yarn between the friction roller and the bobbin.

Description

technical field [0001] The present invention relates to a wire guiding device of a coiler, and more specifically, relates to a coiler that can improve the tension of the wire during high-speed coiling, and can guide a variety of wires to prevent poor coiling wire guiding device. Background technique [0002] refer to Figure 1a , showing the front view of the wire guide device of the existing coiler, refer to Figure 1b , expressing the Figure 1a The silk path formed by the silk guiding device. [0003] As shown in the figure, the wire guide device 100' of the existing coiler is located on the upper part of the spool for winding the wire at high speed, and is roughly in the shape of a quadrangular frame, and a circle concave inward is formed in the lower part near the aforementioned spool. The main body 10' of the shape part 12'; and the friction roller 20' which is combined with the circular part 12' of the main body 10' and contacts with the aforementioned bobbin and ro...

AI Technical Summary

Problems solved by technology

[0006] However, the yarn guide device of this conventional coiler has the following problems due to the gradual increase in the coiling speed of the bobbin

[0007] First of all, with the increase of the rotation speed of the bobbin and the friction roller, it is not only difficult to improve the physical properties such as the tension of the thread by using only the aforementioned friction roller, but also has the problem of degrading the physical properties.

[0008] Second, due to the high-speed contact between the spool and the friction roller and the silk, the contact area per unit time and the moment of inertia of the wound silk and the friction roller are relatively increased. Therefore, the silk with various oils is more likely to adhere to the aforementioned friction roller. causing poor coiling

[0009] Third, since the rotational speeds of the bobbin and the friction roller have already been determined, the characteristics of the thread cannot be varied variously with the aforementioned friction roller, and therefore, there is a problem that various requirements of customers cannot be properly met.
