Device for automatically adjusting spinning part winding tension

Abstract

The invention provides a device for automatically adjusting spinning part winding tension. The device comprises a pulling traction roller, a winding roller, a first motor, a second motor and a PLC, wherein the pulling traction roller and the winding roller work independently, the first motor and the second motor drive the pulling traction roller and the winding roller respectively, and the PLC is used for electrically connecting the first motor and the second motor and controlling the rotation speed of the first motor and the rotation speed of the second motor. The device is characterized in that a tension roller is arranged between the pulling traction roller and the winding roller, a tension detector is arranged on the tension roller, and the signal output end of the tension detector is electrically connected with the PLC through a potentiometer. After the winding tension of the tension roller changes, the variable quantity of tension is converted into the voltage change of the potentiometer through the tension detector, the PLC converts the voltage change into an output signal and sends the output signal to the first motor or the second motor, the rotation speed of the pulling traction roller or the rotation speed of the winding roller is adjusted automatically to enable the winding tension to return to the set constant value, and the purpose of adjusting the winding tension in real time is achieved.

Description

technical field [0001] The invention relates to a weaving auxiliary device, in particular to a device for automatically adjusting the winding tension of textile pieces. Background technique [0002] When weaving or winding, the fabric is transmitted through the traction roller and the take-up roller. During the transmission process, the tension of the fabric is different. When the tension of the fabric is too small, the fabric will be bent. Or knotting, when the tension is too large, the fabric is easy to break, so it is necessary to connect a device that can adjust the winding tension from time to time. Most of the tension adjustment in the prior art is manually controlled by mechanical friction brakes, and manual control cannot Realize constant adjustment, the accuracy is low, it is not suitable for use in the automatic production line at the present stage. Contents of the invention [0003] In order to solve the deficiencies in the background technology, the object of ...
