Abstract

The invention discloses a device for applying tension during carbon fiber pulling and a method for applying the same. The device for applying tension during carbon fiber pulling includes a frame, a guide wire dividing assembly, a gravity tensioning assembly and a height adjustment components, the gravity tensioning component is slidably fixed on the frame, there are two guide wire dividing components, and the two guiding wire dividing components are symmetrically arranged on both sides of the gravity tensioning component and are respectively fixed to the frame, and the height adjustment component It includes a cylinder, one end of the cylinder is connected to the frame through a first connecting plate, and the other end is connected to a gravity tensioning assembly through a second connecting plate, and the gravity tensioning assembly is used to apply tension to the carbon fibers between the two guide wire dividing assemblies. The beneficial effects of the present invention are: real-time tension detection of each carbon fiber in any period of traction process can be realized, and the time-specified tension of each carbon fiber in any period of traction process can be realized by adjusting the traction speed.

Description

technical field [0001] The present invention relates to the technical field of mechanical equipment, and more particularly to a device for applying tension in the process of pulling carbon fibers and an application method thereof. Background technique [0002] At present, to prepare carbon fiber or graphite fiber, it is necessary to draw carbon fiber through a drawing machine through a high-temperature carbonization furnace and a graphitization furnace for graphitization treatment, and then perform surface treatment to obtain high-performance carbon fiber. [0003] However, due to the extremely high temperature in the high-temperature carbonization and graphitization process, the furnace mouth and channels in the furnace are generally narrow, and the carbon fiber will have a certain thermal deformation during the ultra-high temperature graphitization process, and the carbon fiber will be broken if the drafting speed is too fast , and the drafting speed is too slow, which wil...
