Preparation method for extruding composite profile from bamboo fiber composition

Abstract

The invention provides a preparation method for extruding a composite profile from a bamboo fiber composition, and belongs to the technical field of bamboo fiber composite profile preparation. The method comprises the step S2 of screening machining: using a screening device for screening mixed particles. The screening device comprises a first-stage splicing screening barrel, a second-stage splicing screening pipe and an excess material guiding splicing pipe which are distributed in a concentric circle shape, the first-stage splicing screening barrel, the second-stage splicing screening pipe and the excess material guiding splicing pipe are sequentially distributed from inside to outside and each comprise an upper part and a lower part, a zero-contact supplement assembly is arranged between the upper part and the lower part, and an automatic screening acceleration mechanism is arranged in the first-stage splicing screening barrel. According to the preparation method for extruding the composite profile from the bamboo fiber composition, the quality of the fiber composite profile product can be improved, meanwhile, the preparation efficiency of the bamboo fiber composite profile can be improved, and the development of the production and preparation processing industry of the bamboo fiber composite profile product is effectively promoted.

[0002] my country is a big bamboo country with rich bamboo plant resources. Bamboo is rich in bamboo fiber. Bamboo fiber is an organic regenerated cellulose fiber. It not only has good air permeability and wear resistance, but also has natural antibacterial, Antibacterial, anti-mite, deodorant and anti-ultraviolet functions are commonly used in paper towels, fabrics and other products, and some are also applied in various composite profiles, but there are still many in the preparation of bamboo fiber composite profiles. The shortcomings of bamboo products inhibit the improvement of production efficiency and quality of composite profile products, and correspondingly reduce the overall management level of bamboo products and the market competitiveness of products.

[0003] The existing bamboo fiber composite profile preparation and processing process is mainly to mix bamboo fiber and other materials in the formula to make granules and then melt them and then carry out molding processing. The degree of difference in the size of the particle mixture affects the quality of the composite profile product. One of the important factors. At present, one of the main measures to reduce the size difference of particle mixture is to sieve the particle mixture through a screening device, but the efficiency of screening is low, which directly reduces the preparation and processing efficiency of composite profiles.
