specific Embodiment 1

[0013] Specific embodiment one, such as figure 1 As shown, the outer yarn tensioner 4 of the direct twisting machine includes a first yarn guide roller 11 fixed on the frame 1, an electromagnetic tensioner 12 installed on the frame 1, and a second yarn guide connected to the electromagnetic tensioner 12 The roller 13 and the electromagnetic tensioner 12 are connected with the control device 14 . After the outer yarn is wound on the second yarn guide roller 13 and the first yarn guide roller 11, it passes through the spindle 3 and the yarn storage disc 10 on the spindle 3 successively, and merges with the inner yarn at the twist leveler 6; the motor 2 is started, The motor 2 drives the spindle 3 to drive the outer yarn to rotate synchronously to form a balloon. When the speed of the motor 2 is stable, the shape of the balloon generated by the outer yarn is stable. At this time, the wrapping angle α of the outer yarn surrounding the yarn storage tray 10 180°-360°, at this time,...

specific Embodiment 2

[0014] Specific embodiment two, such as figure 1 As shown, on the basis of Embodiment 1, an outer yarn tension detection sensor 15 is arranged between the outer yarn tensioner and the spindle, and the outer yarn tension detection sensor 15 is used to detect the magnitude of the outer yarn tension. After the outer yarn is wound on the second yarn guide roller 13 and the first yarn guide roller 11, after passing through the outer yarn tension detection sensor 15, it passes through the spindle 3 and the yarn storage disc 10 positioned on the spindle 3 successively, and is evenly spaced with the inner yarn. The twister 6 converges; the motor 2 is started, and the motor 2 drives the spindle 3 to drive the outer yarn to rotate synchronously to form an air circle. When the motor 2 maintains a stable production speed, the form of the air circle produced by the outer yarn reaches stability. At this time, the outer yarn The wrapping angle α of the yarn surrounding the yarn storage disc ...

Abstract

The invention relates to a direct twisting machine for twisting an outer yarn and an inner yarn into a thread, and the shape of a balloon is controlled by regulating outer yarn tension, thereby achieving the energy-saving purpose. The outer yarn tension is regulated through an outer yarn tensioner, and the real-time control can be realized. During the initial stage of startup of a spindle, a motor is used for driving the spindle to enable the outer yarn to rotate synchronously and further form the balloon, after the motor achieves the stable production speed, the shape of the balloon generated by the outer yarn is stable, and then the wrapping angle of the outer yarn on a yarn storage disc is 180 degrees-360 degrees. Then, the outer yarn tension is adjusted through the outer yarn tensioner, thereby gradually reducing the wrapping angle of the outer yarn surrounding the yarn storage disc to 0 degree, reducing the shape of the balloon, reducing the noise of equipment, reducing the powerconsumption and achieving the energy-saving effect.

Description

technical field [0001] The invention relates to a direct twisting machine for twisting outer yarns and inner yarns into threads, belonging to the technical field of textile machinery. Background technique [0002] Existing direct twisting machine comprises a frame and motor, spindle, outer yarn tensioner, inner yarn tensioner, leveling device, overfeeding device and take-up device installed on the frame respectively, and motor is used for driving The spindle makes the outer yarn rotate to form an air circle. The spindle includes spindle rods, yarn storage discs and other components. The outer yarn passes through the outer yarn tensioner and the spindle into the twist leveler in turn. In the existing direct twisting machine, the outer yarn rotates with the spindle to form a balloon, and the wrapping angle α formed on the yarn storage disc is generally 180°-360°. In this state, the equipment consumes a lot of energy and makes a lot of noise. Contents of the invention [000...
