The weaving process of woven fabrics:
Warping - sizing - parallel - drawing-in and reeding - adjusting machine - weaving - 淚 cloth
Whether it is in the requirements of low cost, or high quality and high efficiency, the parallel link is of great significance.
What is a parallel axis?
Spinning machine is a device that combines multiple warp beams or pulp shafts processed into a single weaving shaft by batch warping machine, sizing machine, and pulping combined machine. It is widely used in the parallel use of cotton, linen, chemical fiber and other fabrics. It can be used as pre-weaving equipment for shuttleless looms such as air jet, water jet, rapier and projectile shuttle
The new type of spindle merging machine has high process requirements
The textile industry is a traditional pillar industry of China's national economy, and it is also a seriously polluting industry. With the development of China's industry, scientific and technological progress, the concept of energy conservation and emission reduction is well-known. Nowadays, many parallel machines use the old parallel control method in the field, which is slow, low function, and noisy. Therefore, it has become a rigid need for enterprises to greatly improve the running speed of the parallel shafting machine, improve the output value and function. A textile machinery factory in Wuxi conforms to the development trend and launches a high-end spindle machine to the shopping mall, but the high-end spindle machine has high process requirements, attaches importance to the high function and stability of the inverter, and requires that the yarn cannot be broken in the event of a power failure.
Regulation requirements of the parallel machine:
1) The tension should be stable, there should be no large or sharp value changes, and the tension hardness of the winding should be adjusted in real time, otherwise the winding disc will simply collapse.
2) The overall linear speed should be stable, and the speed change should be slow during the acceleration and deceleration of the whole machine, and it should not be changed sharply, otherwise the warp wire will be loosened or stretched.
3) The target value of unwinding tension should be changed in real time according to the change of the winding diameter, and the actual value should be consistent with the target value, and there should be no large difference or fluctuation to ensure that the warp tension is constant.
4) The traction roller should follow the change of the speed of the winding roller, and adjust the frequency of the wire feeding speed in real time to ensure that the wire feeding tension is appropriate, so as to avoid stretching or loosening the wire.
Introduction to INVT's Parallel Machine Program
INVT human-machine interface (touch screen) is used for parameter setting and display, which is convenient to operate
AX series programmable manipulator, control dual frequency conversion, dual motor to complete stepless speed regulation, constant linear speed winding, taper tension control
GD600 high-performance multi-drive inverter, accurate control accuracy, beautiful wiring, cabinet space saving more than 50%.
Planning role
Running speed: up to 300m/min
Parallel tension: 100-800Kg for single motor, 200-1500Kg for double motor
Number of unwinding axes: up to 10 axes
Functional features: power failure and continuous yarn, stable tension
Energy-saving and high-efficiency advantages are fully demonstrated
Through the stable operation of a textile machinery factory in Wuxi for nearly a year, INVT's solution plan advantages in the parallel machine have been fully demonstrated, which has significantly reduced customer costs and improved operation efficiency. Goodrive600 high-performance multi-drive inverter effectively ensures the stability and real-time adjustment of the customer's on-site tension and speed of the parallel machine; The PLC and the inverter and the inverter are connected to the network through network cables, which reduces the wiring workload on the customer's site, the wiring is more beautiful, the function is more stable, and the on-site noise is smaller.
