Continuous fiber mixed-length chopping device

Abstract

The invention discloses a continuous fiber mixed-length chopping device. Automatic cutting of continuous fibers is achieved, and short fibers with required length proportions can be obtained. The continuous fiber mixed-length chopping device comprises a conveying mechanism (1), a pressing mechanism (2) and a cutting mechanism (3); the conveying mechanism (1) comprises a first conveying belt (11), a second conveying belt (12) and a conveying plate (13) which are sequentially arranged in a fiber advancing direction, the pressing mechanism (2) is arranged between the first conveying belt (11) and the second conveying belt (12), the front end of the conveying plate (13) is close to the rear end of the second conveying belt (12), and the cutting mechanism (3) is arranged on the second conveying belt (12); and the cutting time sequence of the cutting mechanism (3) can be adjusted according to fiber length gradation.

Description

technical field [0001] The invention belongs to the technical field of composite material chopping equipment, and in particular relates to a continuous fiber mixed-length chopping device. Background technique [0002] The role of fibers mixed into pavement materials mainly includes reinforcement, dispersion, adsorption, stabilization, and viscosity increase. Studies have shown that proper fiber length gradation can give full play to the advantages of fibers and improve the performance of pavement materials. [0003] The existing fiber chopping device, as described in the Chinese invention patent "Carbon Fiber Cutting Device" (application number: 201821248293.5, authorized announcement date: 2019.06.14), includes a base, a cutting part, a fixing part and a transmitting part; There are carbon fiber placement grooves distributed in parallel; the cutting part includes a push-pull device, a fixing plate and a cutting blade; the fixing part is arranged parallel to the cutting part...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned fiber chopping device can only cut continuous fibers into short fibers with a fixed length, and the subsequent application needs to prepare length grading, and the fiber length cannot be precisely controlled, and the chopped quality is low

[0005] Therefore, the existing problems in the prior art are: the efficiency of fiber chopping is low, and the chopping device can only obtain short fibers of a fixed length, which is time-consuming and labor-intensive.
