Description

Fine warping device of paperless glass

Technical Field

The invention relates to the field of glass fiber textile, in particular to a paperless glass fiber warping device.

Background

The glass fiber cloth is prepared by taking medium-alkali or alkali-free glass fiber yarns as raw materials and carrying out alkali-resistant coating treatment. The product has the characteristics of stable structure, high strength, good alkali resistance, corrosion resistance, crack resistance and the like, has the best reinforcing effect, and is simple and easy to construct.

The glass fiber cloth is formed by glass fiber yarn textile yarns, and along with the increasing refinement of the glass fiber yarn textile technology, the warping machine serving as a main machine in the field of glass fiber textile is gradually developed towards the directions of high efficiency, stability, safety and automation. However, in the existing glass fiber warping production process, due to the limitation of the device, the following technical defects still exist:

(1) In the glass fiber spinning process, glass fiber yarns need to pass through a yarn guide plate and a yarn dividing reed from a yarn guide frame to a winding roller. And because the glass fiber yarn is fragile, the wear resistance is poor, the glass fiber yarn is easy to fuzz in the friction process with the yarn guide plate and the yarn guide reed, particularly, the yarn guide reed and the yarn guide plate of the warping machine do not move in the yarn guide process, and the fuzz is easy to be carried in the warping process, so that the surface of the glass fiber cloth is not flat, and the product quality is influenced. While some existing warping devices, such as CN206570472US, achieve the continuous change of the contact surface between the glass fiber yarn and the reed plate by driving the reed to move up and down, so as to achieve the effect of alleviating the fluffing of the glass fiber yarn. However, the steel reed with such a structure cannot adjust the angle of the reed plate and displace the reed plate left and right, and has a limitation in use.

(2) Because the warp direction tightness of most fabrics of current warping device production is less than 80%, so the warp is not close to the range to the breadth of warp beam is fixed, all is greater than into the cloth breadth, and this results in the range density of yarn littleer, and the spacing distance between adjacent yarn is far greater than the diameter of yarn, and in addition, the warp beam breadth of traditional wind-up roll and the interval between the coiled hair all can have great clearance, lead to the yarn to take turns to the extremely easy emergence diffusion overlap phenomenon of in-process. Therefore, in order to avoid overlapping and disordering between warping glass fiber yarn layers, manual paper padding is required, full-automatic operation cannot be achieved, manual dependence is strong, and accordingly textile cost is increased and textile efficiency is reduced.
