Novel electronic yarn discharging machine yarn guide device

Abstract

The invention discloses a novel electronic yarn discharging machine yarn guide device comprising a yarn guide hook, a traction module driving the yarn guide hook to move back and forth to guide yarn, a first motor positively-reversely driving the traction module to draw the yarn guide hook to move back and forth and a second motor. A torsion energy storage mechanism producing torsion to drive the first motor to quickly steer is arranged between an output shaft of the first motor and an output shaft of the second motor; and the yarn guide device is further provided with a rotation control module controlling rotation angular displacement differences between the output shaft of the first motor and the output shaft of the second motor to enable the torsion energy storage mechansim to produce torsion. The novel electronic yarn discharging machine yarn guide device can be easily manufactured, yarn guiding and steering time can be reduced; and the yarn guide device possesses great practicality.

Description

[technical field] [0001] The invention relates to a novel yarn guide device on an electronic yarn arrangement machine. [Background technique] [0002] 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, but also can ...

Problems solved by technology

[0003] 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
