Device for long-term sampling and filament collecting under various working conditions

Abstract

The invention provides a device for long-term sampling and filament collecting under various working conditions. The device for long-term sampling and filament collecting under the various working conditions comprises a filament guiding wheel, a speed adjusting mechanism, a power switch, a filament ingot pressure adjusting mechanism, a base, wheels, an automatic tension adjusting mechanism with scales, a filament breaking contact alarm mechanism, a detachable tension spring, a filament collecting style adjusting mechanism, a uniform filament laying mechanism, a main motor and a power transmission system. The wheels are arranged under the base. The filament collecting style adjusting mechanism, the uniform filament laying mechanism, the main motor and the power transmission system are installed in the base. The main motor outputs power through a belt and gears. The automatic tension adjusting mechanism, the filament breaking contact alarm mechanism and the detachable tension spring arelocated above the base. According to the device for long-term sampling and filament collecting under the various working conditions, the real-time continuous filament collecting and sampling under thevarious working conditions of a production line are achieved, and filaments are sampled stably in time under the conditions of suspected abnormality, random sampling, test sampling and the like, so that the on-site production is effectively supervised.

Description

technical field [0001] The invention relates to a device for long-term sampling and collection under various working conditions, in particular to a small-sized device for long-term stable collection of filaments used for pre-oxidized filaments in each section of carbon fiber carbonization production and sampling in the production process of carbon filaments. device. Background technique [0002] Carbon fiber is an industry supported by the state, and polyacrylonitrile-based carbon fiber accounts for more than 80% of the total output of carbon fiber. Pre-oxidation, carbonization and surface treatment and sizing processes are necessary and important core steps in the production process of polyacrylonitrile-based carbon fibers. Because different batches of polyacrylonitrile precursors are not significant microscopically, they will show obvious differences in carbonization production. At the same time, because the process of carbon fiber itself is long, there are many influenci...
