An oiling device for spinning fiber production

Abstract

The invention discloses an oiling device for spinning fiber production and belongs to the technical field of carbon fiber production equipment. The oiling device comprises an oiling trough and an oiling agent circulating system communicated with an inlet and an outlet of the oiling trough. The oiling agent circulating system comprises a preparation tank communicated with the inlet of the oiling tank, an overflowing tank communicated with the outlet of the oiling tank and a stock solution treatment tank communicated with the preparation tank and the overflowing tank. A plurality of flower rolls and a plurality of smooth rolls are mounted in the oiling trough in parallel alternately, each of the flower rolls consists of a central roll body and 8-25 peripheral roll bodies evenly distributed around the central roll body, and the diameter of each central roll body is 7-15 times of that of each peripheral roll body. The oiling device for spinning fiber production has the advantages that the flower rolls arranged in the oiling trough are used for stirring the oiling agent in the oiling trough to accelerate relative movement between the oiling agent and fiber bundles, so that the effect that the oiling agent permeates into the fiber bundles is improved; the oiling agent in the oiling trough is mixed more uniformly.

Description

technical field

[0001] The invention relates to an oiling device for spinning fiber production, belonging to the technical field of carbon fiber production equipment. Background technique

[0002] Carbon fiber is an inorganic polymer fiber with a carbon content of more than 90%. In addition to the high temperature resistance, friction resistance, corrosion resistance, and electrical and thermal conductivity of general carbon materials, it also has softness, machinability, light weight, and high specific strength. characteristics, thus being widely used in many fields such as military, textile, sports equipment, chemical industry, medical equipment and mechanical processing.

[0003] In the continuous production process, the surface of the carbon fiber precursor must be oiled or sized, so that the fibers can be bundled and then pass through the subsequent processes smoothly, such as drying and densification, steam drafting, etc. At present, the oiling methods of carbon fiber...
