Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber processing, in particular to an extrusion wire drawing device. Background Art

[0002] The carbon fiber extrusion drawing device is a special equipment used to process carbon fiber materials into filamentary materials with specific diameters and properties. This device plays an important role in the production process of carbon fiber. It draws the carbon fiber raw yarn into filaments with desired size and properties through mechanical stretching.

The utility model is provided with a pressure switch. When the carbon fiber precursor is finished, the machine pressure switch is not subjected to pressure, and the machine automatically stops running to ensure that the end of the carbon fiber precursor will not be taken away by the machine.
