Digital doubling and twisting tester

Abstract

The invention discloses a digital doubling and twisting tester, which comprises feeding mechanisms, tension mechanisms, twisting and winding mechanisms and forming mechanisms symmetrical on two sides and a digital control system which takes a touch screen as an interface. The digital doubling and twisting tester is characterized in that: a bottom-roller servo motor is mechanically connected with a bottom roller through a bottom-roller speed reducer and a bottom-roller telescopic universal coupling in turn; the bottom-roller servo motor is an independent servo motor and is driven and controlled by a bottom-roller AC servo driving controller of the digital control system through the touch screen; a rolling disc and an encoder in the twisting and winding mechanism are arranged on a shaft of a spindle variable frequency motor; the spindle variable frequency motor is an independent variable frequency motor and is driven and controlled by a spindle frequency converter of the digital control system through the touch screen; and a forming motor in the feeding mechanism is an independent servo motor and is driven and controlled by a forming AC servo driving controller of the digital control system through the touch screen.

Description

technical field [0001] The invention relates to a textile machine, in particular to a digital doubling and twisting testing machine for doubling and twisting plied yarns. Background technique [0002] The traditional doubling and twisting machine is driven by a main motor, the motor drives the roller shaft through the V-belt, and the roller shaft drives the roller and the forming device through the gear train. The spindle speed of the traditional parallel twisting machine usually has no feedback control, and the deviation of the spindle speed will easily cause the yarn tension and twist deviation. When changing the spindle speed, it is necessary to replace the roller pulley or the motor pulley; when changing the twist, it is necessary to replace the twist changing gear; Replace the lift conversion gear. Therefore, the traditional doubling and twisting machine is equipped with a large number of gears, and the operation is relatively cumbersome, which brings great inconvenie...
