AI Technical Summary

Technical Problem

In a warping machine, when the yarn is hooked by the rapier hook, it loses its restraint after being released from the yarn clamp, causing the yarn to swing wildly. It may become entangled in other parts or become entangled in itself, resulting in knots at the yarn end and yarn breakage.

Method used

Design a yarn limiting mechanism, including a mounting base, a first limiting member and a second limiting member. By moving the limiting member in a specific direction, the yarn swing between the yarn clamp and the rapier hook is restricted to prevent random swinging. The limiting side contacts the yarn to form a closed loop or tension effect, thereby achieving stable yarn extraction.

Benefits of technology

It effectively prevents yarn from flying around, avoids tangling with other parts or itself, reduces the risk of yarn breakage, and ensures stable yarn transmission.

Abstract

This utility model discloses a yarn limiting mechanism and a warping machine. The yarn limiting mechanism is used to restrict the yarn swing between the yarn clamp and the rapier hook. The yarn limiting mechanism includes a mounting base, a first limiting member, and a second limiting member. The first limiting member is connected to the mounting base and includes a first limiting portion. The second limiting member is connected to the mounting base and includes a second limiting portion. The first limiting portion and the second limiting portion are distributed along a first direction. The first limiting member and the second limiting member can move relative to each other along a second direction, so that the first limiting portion and the second limiting portion are close to each other and jointly restrict the yarn swing, or so that the first limiting portion and the second limiting portion are far from each other and release the restriction on the yarn. The second direction intersects the first direction. The yarn limiting mechanism of this utility model can prevent the yarn from swinging wildly between the yarn clamp and the rapier hook.
