Automatic control device capable of moving light yarn tension and control method thereof

Abstract

The invention discloses an automatic control device capable of moving light yarn tension and a control method thereof. The automatic control device comprises a first supporting plate, wherein a light yarn conveying device is arranged above the first supporting plate, a material collecting and discharging device is provided with a third motor, an air cylinder and a reduction gearbox, the third motor operates to drive the whole light yarn to start to move, the air cylinder operates to drive a pressing roller frame body to rotate, the pressure of a silica gel pressing roller on a traction roller is adjusted, so that the tension of the light yarn is adjusted, the reduction gearbox operates to reduce the rotating speed of the traction roller, so that the tension of the light yarn is adjusted; the light yarn conveying device is provided with a first motor and a second motor, the first motor operates to drive a ball screw to rotate, the ball screw rotates to drive a conveying plate to slide along the ball screw, so that the whole conveying mechanism is driven to slide along a T-shaped supporting block, and then the tension of the light yarn is adjusted; and the second motor rotates to drive a worm to rotate, the worm rotates to drive a turbine to rotate, the turbine rotates to drive a first fixing frame to move up and down, so that the distance between a first conveying roller and a second conveying roller is adjusted to adjust the tension of the light yarn.

Description

technical field [0001] The invention relates to the field of light yarn tension control, in particular to an automatic control device and a control method for movable light yarn tension. Background technique [0002] Yarn tension is a very important parameter. The size and stability of tension are directly related to product quality, production efficiency and the smooth progress of subsequent processing. In the winding process, whether the tension control is appropriate is directly related to the quality of bobbin forming. If the tension is too small, it will cause deformation, bending and other undesirable phenomena; this will also cause a certain deformation of the yarn at this stage, which is not conducive to the production of high-quality products in the later stage, so the control of tension in the winding process very critical. Contents of the invention [0003] In order to solve the above-mentioned deficiencies mentioned in the background technology, the object of ...
