Carbon fiber tow layered conveying device

Abstract

The invention discloses a carbon fiber tow layered conveying device which comprises a tow collecting device and a tow expanding device. The tow collecting device is provided with a machine frame, a first rotating guide roller and a second transmission guide roller are arranged on the upper portion of one side of the machine frame, a first guide roller is fixed below a second rotating guide roller on the machine frame, a second guide roller is fixed below the first guide roller on the machine frame, a first supporting roller and a second supporting roller are fixed on the upper portion of the other side of the machine frame, a third guide roller is fixed below the first supporting roller on the machine frame, a fourth guide roller is fixed below the third guide roller on the machine frame, and the tow collecting device and the tow expanding device are of the same symmetrical structure. The tow collecting device and the tow expanding device are respectively placed on the front of a carbide furnace and on the back of the carbide furnace, the tow collecting device is capable of achieving layering and collecting of tows, and the tow expanding device is capable of achieving expanding of the tows.

Description

technical field [0001] The invention relates to a tow transmission device on a fiber production line, in particular to a carbon fiber tow layered transmission device. Background technique [0002] When the carbon fiber tow is traveling on the production line, it needs to be narrowed and layered before entering the carbonization furnace, and it needs to be widened and merged after it comes out of the carbonization furnace. At present, the method used to realize the narrowing and widening of carbon fiber tow on the production line is to set two wire combs or fiber collecting plates with holes in the front and rear of the carbonization furnace respectively, and to make the rotating guide roller before the tow enters the carbonization furnace. Half of the upper silk web passes through two splitting combs or collecting plates, the first comb or collecting plate deflects half of the tow in the direction, and the latter comb or collecting plate deflects the half-width tow again Co...

AI Technical Summary

Problems solved by technology

Although the existing dividing comb or collecting plate can realize the narrowing and layering of the carbon fiber tow, because the layering, narrowing and expanding in the traveling of the tow are carried out through the separating comb or collecting plate It is realized by forced guidance, the friction between the tow and the separating comb or collecting plate is high, it is easy to produce fluff, which greatly reduces the quality of the fiber
