Processing system and technology for natural fibrous composite felt used for automotive trim plate core layer

Abstract

The invention discloses a processing system and technology for natural fibrous composite felt used for an automotive trim plate core layer. The system comprises a fiber net generating device. The fiber net generating device is connected with a drying oven through a bottom curtain, the bottom curtain is provided with a driving structure, fiber nets which come out of the drying oven pass through a hot pressing device and extends to a winding device, a cloth guide roller used for winding the fiber nets to be in a S shape and a supporting conveying roller are arranged in the drying oven, the hot pressing device is a pair of heating and compressing rotary rollers, the fiber net generating device comprises an opening device, a carding device and a net paving device, and the opening device, the carding device and the net paving device are connected in sequence. The processing system and technology for the natural fibrous composite felt used for the automotive trim plate core layer are low in cost, high in performance, environmentally friendly and capable of greatly improving the strength and tenacity of the natural fibrous composite felt, and the natural fibrous composite felt can be used as base materials of various automobile trim plates with high strength requirements.

Description

technical field [0001] The invention relates to a natural fiber composite material felt, in particular to a processing system and process for a natural fiber composite material felt for automotive interior panels, and belongs to the field of fiber composite material preparation. Background technique [0002] At present, the materials used to manufacture the substrates of automotive interior panels are mostly chemical synthetic materials such as polypropylene and polyurethane. On the one hand, the natural resources for preparing these materials are limited, non-renewable, and pollute the environment during processing; With the development of light weight, high strength, environmental protection and recyclability, the original polypropylene board and its composite board with wood powder and polyurethane board can no longer meet the needs of modern automobile development, so various natural fibers are further recognized by people And into the field of auto parts production. ...

AI Technical Summary

Problems solved by technology

The current fiber mats mostly adopt needle-punching pre-setting method. In the material preparation stage, independent pieces of rectangular fiber mats are obtained, and then hot-pressed one by one on the composite mold, which lacks the integrated design of composite material preparation and molding processing. , did not give play to the more direct help of the material preparation stage to the material forming stage, resulting in a low degree of automation during hot pressing, requiring additional and complicated conveying mechanisms, grippers, and positioners. The labor intensity of the workers is high, and the product quality is unstable. high production cost
