Embodiment 1

[0030] Such as image 3 Among them, an electric tensioner includes a tension motor 101 and a yarn guide disc, the tension motor 101 is fixedly connected to the frame 9, the tension motor 101 is fixedly connected to the yarn guide disc, and the yarn 2 bypasses the yarn guide disc. Yarn 2 in this example refers to the outer yarn.

[0031] In a preferred solution, in the yarn guide disc, the inner disc seat 103 is fixedly connected to the output shaft of the tension motor 101, and the inner disc seat 103 is fixedly provided with an inner flower disc 104; specifically, the threaded section 107 of the inner disc seat 103 is sleeved on On the output shaft of tension motor 101, fix by fastening screw 102. The threaded section 107 is provided with external threads;

[0032] The outer disc base 106 is fixedly connected with the inner disc base 103 , and the outer disc base 106 is fixedly provided with an outer flower disc 105 . The outer disc seat 106 is fixedly connected with the t...

Embodiment 2

[0036] Such as figure 1 , 2 Among them, on the basis of Embodiment 1, a twisting machine using the above-mentioned electric tensioner is provided with an electric tensioner between the creel 3 and the spindle 8 of the twisting machine.

[0037] In a preferred solution, only one electric tensioner is provided between the creel 3 and the spindle 8 of the twisting machine as the outer yarn tension control component.

[0038] In a preferred solution, with reference to the moving direction of the yarn 2, a guide tube 4 is provided upstream of the electric tensioner 1, and a guide wheel 5 is provided downstream;

[0039] Such as image 3 As shown in , there is a distance between the guide tube 4 and the guide wheel 5 along the axial direction of the electric tensioner 1, so that the yarn 2 contacts the inner flower disc 104 when entering the yarn guide disc of the electric tensioner 1, and leaves The yarn guide disc of the electric tensioner 1 is in contact with the outer flower ...

Embodiment 3

[0043] On the basis of embodiment 1,2, a kind of tension control method that is used for above-mentioned twisting machine comprises the following steps:

[0044] s1. When starting, the control device controls the electric tensioner 1 to rotate along the yarn feeding direction for a period of time T1; this structure can greatly reduce the strong damage caused by static friction. It is also one of the important reasons why the structure of the present invention can reduce the strength loss. T1 is 0.5-5 seconds, preferably 2-3 seconds.

[0045] s2. The control device controls the electric tensioner 1 to run for a period of time T2 in a damping manner; T2 takes 5 to 300 seconds, preferably 30 seconds.

[0046] During the operation of the power generation mode, the damping of the electric tensioner 1 is controlled by the damping adjustment circuit; the control device outputs PWM output pulse width modulation PWM signal to the damping adjustment circuit, and the damping adjustment c...

Abstract

The invention provides an electric tensioner, a twister, and a tension control method. The electric tensioner includes a tension motor and a yarn guiding disc; the tension motor is fixedly connected to a rack; the tension motor is fixedly connected to the yarn guide disc; the yarn guide disc is used for allowing yarn to bypass and transmitting resistance to yarn; only one electric tensioner is arranged between a yarn support and a spindle of the twister as an outer yarn tension control assembly. The tension control method includes the following steps: during starting, a control device controlsthe electric tensioner to rotate along the yarn conveying direction for a period T1; the control device controls the electric tensioner to operate in a damping manner for a period T2; after a ballonof the yarn is stable, a detection device gradually increases a reverse torque of the electric tensioner, the rotation speed of a motor of the spindle is kept, and the shape diameter of the ballon reaches a minimum in a permission range. The above steps can reduce energy consumption by controlling the tension of yarn, can reduce the strength loss of the yarn, and can improve the yarn quality.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to an electric tensioner, a twisting machine and a tension control method. Background technique [0002] Existing twisting machines include direct twisting machines and two-for-one twisting machines, all of which need to adjust the size of the yarn balloon to reduce energy consumption in the twisting process. The adjustment method is to use a tensioner to control the tension of the yarn, thereby adjusting the shape of the balloon. [0003] Chinese patent document CN 102995185 B describes a yarn feeding device, which includes a yarn brake 11 and an active yarn feeding device 13, wherein the yarn brake 11 is a hysteresis brake. The problem with this structure is that the yarn passes through more friction Surfaces, such as the friction disk of the yarn brake 11 and the friction disk of the active yarn feeding device 13, the operation and maintenance of this structure is complicated, a...
