Drawing machine for producing carbon fiber

Abstract

The invention relates to a drawing machine for producing a carbon fiber. The drawing machine comprises rollers and a frame, wherein the rollers are divided into two layers, each layer is provided with three rollers, the rollers on each layer comprise a transmission roller and auxiliary rollers, the transmission roller of the upper-layer rollers is provided with a hydraulic or mechanical lifting device, and the frame right above the upper-layer rollers is provided with a limiting mechanical switch and an automatic induction switch. The drawing machine disclosed by the invention has extremely important significance in the safety of personal life and equipment, can be used for greatly reducing the equipment damage rate, also can be used for saving energy, and has great effects on improving the industrialization capacity and improving the quality and quantity of products.

Description

technical field

[0001] The invention relates to the field of carbon fiber or special fiber production equipment, in particular to a drafting machine for producing carbon fiber. Background technique

[0002] The three-roller double-layer drafting machine for the production of PAN-based high-strength carbon fiber and special fiber is an indispensable main equipment for the production line. The main functions of the three-roller double-layer drafting machine are firstly to drive the fibers forward, secondly to restrain, arrange and position the fibers during the production process, and thirdly to increase or decrease the draft ratio according to the needs of the fiber production process to control the transmission. The traditional three-roll double-layer drafting machine is an experimental device and has been used for several years. Although the machine can basically meet the production needs of carbon fiber or special fiber, there are many insurmountable technical and safety ...
