Direct twistless roving production device for glass fibers

Abstract

The invention discloses a direct twistless roving production device for glass fibers. The device comprises a bushing plate, a sprayer located below the bushing plate and used for spraying mist to cool yarn, an oiler located below the sprayer and used for coating the yarn with an impregnating compound, a bundling device located below the oiler and a winding device located below the bundling device, wherein the winding device comprises a wire drawing machine head, a machine arm arranged beside the machine head and a wire arranging device arranged on a groove drum in the machine arm, the machine arm is further provided with a front side roller and a rear side roller which are used for blocking yarn, and the arrangement positions of the front side roller and the rear side roller on the machine arm correspond to the limiting positions of the wire arranging device moving forwards and backwards along the groove drum. When the yarn moves to the joint part of a yarn guide surface and a non-yarn guide surface along the yarn guide surface, the yarn can be blocked by the front side roller and the rear side roller, so that glass fibers are arranged in a dispersed manner, thus the yarn can be prevented from being mutually entangled due to excessive concentration, and the problem of external untwisting of twistless roving of the glass fibers is effectively solved.

Description

technical field [0001] The invention relates to the technical field of glass fiber yarns, in particular to a glass fiber direct roving production device and a corresponding production method. Background technique [0002] Glass fiber direct roving is widely used in the production of glass fiber reinforced plastic products. [0003] In the current glass fiber roving winding and forming process, two methods are used to rewind the raw silk cake. One method uses the inner layer of the original silk cake to carry out the original silk rewinding from the inside to the outside. This method is called the inner retreat process. The other uses the original silk cake to start from the outer layer of the original silk cake. It is called retreat process. Glass fiber roving is not twisted, but in the production process, the glass fibers cannot keep parallel to each other, and if multiple glass fibers are too concentrated and entangled with each other, twist will be generated, which will...
