Glass fiber direct roving production device

Abstract

The invention discloses a glass fiber direct untwisted roving production device, comprising a bushing plate, a sprayer positioned under the bushing plate to spray and cool the yarn, an oiler positioned below the sprayer to apply sizing agent to the yarn, and a sprayer positioned below the oiler The bundling device and the winding device located below the bundling device, the winding device includes a wire drawing machine head, a machine arm arranged beside the machine head, and a wire arrangement on the grooved drum arranged in the machine arm, so The machine arm is also provided with a front side roller and a back side roller for blocking the yarn, and the setting positions of the front side roller and the back side roller on the machine arm respectively correspond to the limit of the front and rear movement of the thread arranging device along the groove drum. corresponding to the location. When the yarn moves along the yarn guide surface to the junction of the yarn guide surface and the non-yarn guide surface, the front side roller and the rear side roller can be arranged in the present invention to block the yarn, so that the glass fibers are dispersed and arranged, so as to avoid the yarn The mutual entanglement caused by the excessive concentration of the threads effectively solves the problem of the untwisted outside of the glass fiber roving.

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. Called the 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 c...

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a glass fiber direct roving production device to solve the technical problems in the prior art that the glass fiber roving will produce twist when the glass fiber roving retreats, and the roving is easy to produce hairiness
