Roughing-up machine multi-shaft drive tension control system and method for controlling tension thereof

Abstract

The invention relates to a roughing-up machine multi-shaft drive tension control system and a method for controlling tension thereof. A cloth guiding control system in a tension control system based on constant tension control comprises a tension sensor arranged on a roughing-up machine, a roughing-up tension sensor, an upper guiding tension sensor, a cloth discharging tension sensor and a PLC controller connected with the tension sensors, wherein the PLC controller is connected with various servo drivers which are respectively used to drive a cloth feeding roller motor, a front guiding roller motor, a rear guiding roller motor, a cloth discharge roller motor and an upper guiding roller motor. The PLC controller further controls a roughing-up control system through various frequency-changers. The method for controlling tension comprises the following steps: receiving the tension value sent by the tension sensors in real time by the PLC controller, using a PD control algorism based on manual interference to calculate the rotation speed variable quantity of each roller motor according to the tension set values, and sending to the servo drivers to drive each roller motor to rotate. The system and the method improve the tension control precision, guarantee constant tension in the operation process of the roughing-up machine, and enable each tension value to be more stable.

Description

technical field [0001] The invention relates to a sanding machine, in particular to a multi-axis transmission tension control system of a sanding machine and a tension control method thereof. Background technique [0002] High-efficiency and multi-functional ultra-soft suede finishing machine, mainly suitable for soft and suede processing of pure cotton and blended fabrics and knitted fabrics, especially capable of flexible processing of high-grade thin fabrics and embossed fabrics. The development of sanding finishing machines is only a few decades old. Some high-end ultra-soft sanding finishing machines mainly in Germany and Italy were born in the 1990s. The research and development of domestic sanding machines began in the early 21st century. At present, the general trend of the development of domestic and foreign sanding machines is environmental protection, green, Energy saving, low consumption, high efficiency and intelligence. [0003] The tension of the fabric is t...
