Film-coating method for glass fiber yarn cluster

Abstract

The invention discloses a film-coating method for a glass fiber yarn cluster, and belongs to the technical field of glass fiber production equipment. The invention aims to provide the film-coating method for the glass fiber yarn cluster, and the coating method is relatively good in coating effect and is high in film-coating efficiency. The film-coating method comprises the following steps: step I: conveying yarn clusters; step II: grabbing the yarn clusters; step III: pressing the yarn clusters; step IV: coating a film, wherein a coating film is pushed to a specific position through a film feeding device, a gas blowing tube of a film cutting mechanism of the film feeding device works to blow the coating film; and the coating is adhered on the yarn cluster in a sticky mode, and the coating film is pressed onto the yarn cluster through a film-pressing thin sheet of the film pressing device; a clamping rotating device drives the yarn cluster to rotate, the coating film is continuously guided out and is coated on the cluster yarn; and the film is cut off through a blade of a film cutting mechanism; step V: pushing a film, wherein the film pressing device moves upwards and the film pressing device works to level the coating film exceeding the upper end surface of the yarn cluster to the upper end surface of the yarn cluster; and step VI: outputting finished products. The film-coating method is a film-coating method suitable for coating a layer of film outside the glass fiber yarn cluster.

Description

technical field [0001] The invention belongs to the technical field of glass fiber production equipment, and relates to a coating machine for coating a layer of film on a glass fiber yarn ball. Background technique [0002] Glass fiber yarn cluster, that is, glass fiber yarn cluster, is wound from a tow composed of many single fibers with a diameter of <24um drawn from molten glass. Since the essence of glass fiber yarn is still glass, it is very easy to cause mutual friction and collision during packaging and transportation to break, which affects product quality and use. Therefore, it is necessary to arrange a layer of film outside the finished glass fiber yarn group for protection. [0003] In the glass fiber industry, when the finished glass fiber is wrapped and packaged, the glass fiber is input by two parallel butt-joint conveyor belts; the V-shaped guide tube is used for initial positioning, and then sent to the working device; after the sensor detects the positio...
