Fuzzing roller rolled by carbon fiber composite material in two-step method

Abstract

The invention discloses a fuzzing roller rolled by a carbon fiber composite material in a two-step method. The fuzzing roller comprises a roller body of the fuzzing roller and shaft heads, wherein the shaft heads are arranged at the two ends of the roller body. A preparation method for the fuzzing roller comprises the following steps of: firstly, winding a carbon fiber preimpregnated cloth on a designed mould core rod to make a carbon fiber inner lining tube for later use; coating an adhesive in adhesion sections of the shaft heads; inserting the adhesion sections into the carbon fiber inner lining tube for adhering; and finally winding the carbon fiber preimpregnated cloth again by using the carbon fiber inner lining tube as a core rod and covering reinforcing shaft shoulders of the shaft heads into the carbon fiber inner lining tube at the same time to perform the steps of curing coarse processing, refine processing and coating to finally prepare the fuzzing roller serving as a finished product. The fuzzing roller is light in weight, and good in linearity degree, fatigue resistance and rigidity, so that the binding of the carbon fibers and resin is high, and the compactness is high; and because the binding strength of the fuzzing roller is greatly higher than that manufactured in a one-step method, and the service life of the fuzzing roller is prolonged. The carbon fiber composite material and the metal shaft heads are adhered by coating for twice, so that a contact surface of a carbon fiber tubular wall and the metal shaft heads is enhanced, the adhesion is firm, and the integral strength of the fuzzing roller of the carbon fiber composite material is greatly improved.

Description

technical field [0001] The invention relates to a napping roller of a textile machine, in particular to a napping roller for rolling carbon fiber composite materials in two steps. Background technique [0002] In the production process of textiles, the plain weave fabric can achieve the expected plush effect through fluffing, so as to obtain a warm and comfortable textile fabric. This kind of fabric is the first choice for thermal underwear, outdoor clothing, and sports clothing. Therefore, customers continue to put forward higher requirements for the raising effect and raising efficiency of the high-speed raising machine, and the raising roller, which is a key component of the raising machine, is constantly improving at the same time. [0003] Since the development of the raising machine, the raising roller has been continuously updated. The currently widely used raising roller is a steel raising roller, which still has many shortcomings: 1. The steel raising roller is hea...

AI Technical Summary

Problems solved by technology

[0003] Since the development of the raising machine, the raising roller has been continuously updated. The currently widely used raising roller is a steel raising roller, which still has many shortcomings: 1. The steel raising roller is heavy, which leads to high energy consumption of the equipment and high transportation costs.

When it is necessary to further increase the speed of the raising machine, the wall thickness of the steel raising roller needs to be continuously increased to meet the higher rigidity requirements. Therefore, the self-weight of the equipment is further increased, and the energy loss is more serious; 2. The fatigue resistance of the steel raising roller Not good, due to the ductility of metal, with the high-speed operation of the raising machine, the steel raising roller will gradually accumulate deformation until it is completely deformed and cannot be used
