Project Description
According to the existing glass fiber rapier weaving (loom) and low efficiency (jet loom) weaving speed (less than 650rpm) is relatively low and unstable performance of the status quo, proposed high-speed glass fiber weaving technology. Mainly due to: first, glass fabrics is rigidity, high hardness materials, it will affects the loom speed and the quality of the fabric, the existing domestic air-jet loom can not solve the problem of pressing selvage and weft yarn cutting, so solving the problems, especially the problem of cutting the weft in high speed weaving condition. Second, because at the beginning the filling wrapped , sometimes the weft yarn quality is not stable, easy to cause fluff, fiber broken and other such above defects is easy to put these defects are woven into cloth, caused by quality problems, become waste cloth, cloth. Third, the glass fiber yarn properties (hardness, rigidity, glass fiber, crimp resistance) in the process of weaving fiber glass cloth, because the weft shrinkage, easy to appear small wave like wrinkles in the cloth roller, cause effect to fabric quality, especially in weaving think fabric. So in 2014, company decide to R&D This project for solving such above problem
User Value
1. Electric intelligent yarn pressing technology and device: in order to glass fiber cloth edge of the problem, the computer programming control technology and electric intelligent edge device development. Improve the weaving efficiency of glass fiber: under normal working conditions, the loom speed can reach to 650rpm-800rpm, while the existing rapier loom maximum speed is 300rpm, and the spindle speed is about 600rpm under the normal condition of the ordinary air-jet loom. 2. left cutting and suction weft broken technology and equipment: weft cutting, chopping, breaking weft absorption of two major technology and its cutting and cutting device, linkage, suction and weft device development. Improve efficiency: take a left boot cut chop suction technology, spiral weft crease defect online induction technology, the glass fiber weft, weaving quality can be improved obviously, but also can improve the power efficiency. 3. Weft defect on-line detection technology and device: reduce the number of broken weft. The air bag and the electromagnetic valve affinity technology, main injection pressure by electric proportional valve, accurate calculation, high precision, automatic adjustment pressure, energy saving, and can effectively prevent the wire breaking phenomenon caused by the fluctuation of weft arrival time. 4. Screw anti crease technology and device: in weaving process, due to the shrinkage of weft, it is easy to appear small wave like wrinkles, affecting the quality of cloth. We re design a new cloth rolling mechanism and the increase of the spreading device. In particular, the different coiling methods of constant torque mode, constant tension mode and piecewise linear mode suitable for weaving different kinds of glass fiber cloth are studied. 5. Electric control system: three coiling control modules, an electronic yarn module and an on-line monitoring module of weft are added on the basis of the original function.
