Description

Technical Field

[0001] The utility model belongs to the technical field of process equipment design and manufacturing of composite material manufacturing, and relates to a tension scraping device in a winding forming process of a resin-based fiber-reinforced composite material. Background Art

[0002] The wet winding of continuous fiber yarns using winding machine equipment is a widely used molding process for the manufacture of resin-based fiber-reinforced composite materials. The impregnation system of the winding machine equipment must complete the full impregnation of the fiber yarns and provide a certain continuous fiber winding tension. During the winding process, the fiber yarns coming out of the impregnation tank usually come with a large amount of resin glue. It is necessary to use a tension scraper device to remove some of the free-flowing glue on the surface of the fiber yarn to meet the requirements of the winding process, and use the tension scraper device to squeeze the surface of the fiber yarn to make the fiber yarn more fully impregnated. At the same time, the tension scraper device squeezes the surface of the fiber yarn to provide traction tension during the winding process of the fiber yarn. Therefore, the role of the tension scraper device has a great influence on important winding process technical parameters such as the scraping effect of the fiber yarn, the impregnation quality and the tension control of the fiber yarn.

[0003] The tension scraping device widely used at present adopts a pair of rubber squeezing rollers to be pressed on the support by a screw at each end. During winding, the fiber yarn passes through the pair of pressed rubber squeezing rollers and drives the rubber squeezing rollers to roll. The pair of pressed rubber squeezing rollers are used to roll to remove excess resin glue on the surface of the fiber yarn and provide traction tension for the fiber yarn. The shortcomings thereof are: when the pair of rubber squeezing rollers are pressed by screws, the magnitude of the pressing force is difficult to control each time, resulting in uncertain squeezing force of the rubber squeezing rollers on the fiber yarn, affecting the scraping effect of the fiber yarn, affecting the quality of the fiber yarn dipping, and affecting the tension consistency of the fiber yarn during the winding process. In particular, the degree of pressing at both ends of the rubber squeezing rollers is inconsistent each time, and even the deviation is large, so that the contact extrusion surfaces of the pair of rubber squeezing rollers form an oblique gap along the axial direction, resulting in greater impact on the above-mentioned effects, seriously reducing the quality of composite material winding products.
