A New Type of Yarn Guide Device on Electronic Yarn Arranging Machine

Abstract

The invention discloses a novel yarn guide device on an electronic yarn arrangement machine, which includes a yarn guide hook, a traction module for driving the yarn guide hook to move back and forth for yarn guidance, and a traction module for driving the traction module forward and reverse A first motor that pulls the yarn guide to move back and forth, and a second motor, the output shaft of the first motor and the output shaft of the second motor are provided for generating torque to drive the first motor to change direction quickly The torsional energy storage mechanism, the yarn guiding device also includes a rotation control module for controlling the rotational angular displacement difference between the first motor output shaft and the second motor output shaft so that the torsional energy storage mechanism generates torque . The structure of this case is simple and easy to implement, effectively shortens the time for yarn guiding and reversing, and has good practicability.

Description

[0001] [technical field] [0002] The invention relates to a novel yarn guide device on an electronic yarn arrangement machine. [0003] [Background technique] [0004] There are many well-known yarn arrangement methods in the yarn winding process: yarn arrangement by groove drum-random winding, yarn arrangement by paddle-mechanical precision winding, electronic yarn arrangement-digital precision winding, etc. As a kind of high-speed precision winding, the electronic yarn arrangement uses a high-speed, high-precision stepping motor to drive the steel wire rope equipped with the yarn guide hook to reciprocate through the wire wheel, and cooperate with the rotation of the bobbin, so as to achieve uniformity from the yarn to the bobbin. Length-controlled layers are stacked to produce high-quality packages of the desired shape and density. Compared with random winding and mechanical precision winding, the electronic yarn arrangement system not only has more different winding modes...

Problems solved by technology

[0005] In order to increase the speed of the yarn guide hook when it changes direction, spring elements are usually used, and there are mainly two types of spring elements used to support the lateral movement of the yarn, one is fixed at both ends of the lateral movement path, and the buffer station The other is directly connected to the stepper motor or through some kind of gearbox and fixed on the mounting base. This special method uses a pair of pre-tightened torsion bars that move in the opposite direction, in order to strengthen the torque as much as possible. The additional force of the rod, using the clutch to shorten the distance between the torsion rod and the two stages of lateral movement, thereby increasing the spring stiffness of the torsion rod, this design concept has certain disadvantages, when the lateral stroke is fixed and set to the maximum stroke, the The device works best, but shortening the transverse stroke or gradually shortening the transverse length, the device cannot achieve the desired effect. For tapered packages, the traverse length must be adjusted continuously
