作品简述
针对现有玻璃纤维剑杆(织机)织造效率低、喷气(织机)织造主机转速(≤650rpm)相对低、性能不稳定等现状,提出了玻璃纤维高速织造技术。主要由于: 一、玻纤刚性大,材质硬度高,其不仅影响到织机开机转速,同时还影响到织物质量,现有国产喷气织机的压边和剪刀根本不能解决高速状态下压边、剪纬问题,因此需要解决剪纬的问题特别是高速织造状态下的剪纬问题。 二、由于纬纱在缠绕的初期,有时质量不稳定,造成起毛、断纤等缺陷,在织布的过程中很容易把这些疵点织进布匹中,造成质量问题,成为次布、废布。 三、受玻纤纱性能(玻纤刚性、硬度、卷曲阻力)影响,在织造玻纤布的过程中,由于纬向的收缩,在卷布辊上易出现小波浪样的皱纹,影响布匹的质量,尤其织造轻薄织物时更容易出现。 因此,公司于2014年立项解决这些问题的研究设计开发
用户价值
1.电动智能压纱技术及装置:为了玻纤布齐边的问题,进行电脑编程控制技术和电动智能压边装置的开发。提高了玻纤织造效率:正常工况下主机转速达到650rpm-800rpm,而现有的剑杆织机主机转速最大300rpm,普通喷气织机正常工况下主轴转速600rpm左右。2.左剪剁吸断纬技术及装置:纬纱剪剁、断纬吸取两大技术及其剪剁装置、联动吸断纬装置的开发。提高了开机效率:采取了左剪剁吸断纬技术、螺旋防皱技术、纬纱瑕疵在线感应技术,使得玻纤织造质量可以得到明显的提高,同时也可提高开机效率。3.纬纱瑕疵在线检测技术及装置:降低断纬次数。采用了气包与电磁阀亲合技术,主喷气压采用电气比例调节阀,计算准确,精度高,自动调节气压,节约能耗,同时可有效防止纬纱达到时间的波动引起的断丝现象。4.螺旋防皱技术及装置:在织造过程中,由于纬向的收缩,在易出现小波浪样的皱纹,影响布匹的质量。为此我们重新设计了新的卷布机构并增加了扩布装置。又特别研究了适用不同品种玻纤布织造的不同卷取方式——恒转矩模式、恒张力模式和分段线性模式。5.电控系统:在原有功能基础上增设三种卷取控制模块、电子压纱模块和纬纱在线监测模块。
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.
