[0003] At present, a commonly used wire extruder is used to melt plastic and extrude it to form chemical fiber filaments. Chinese patent CN210299452U discloses a wire extruder for rice noodle production, including a water bath, a heating plate, a first motor, a second motor and a cylinder. The bottom of the water bath is fixed with a bracket, and the inside of the water bath is fixed with a heating plate. A fixed pipe is installed through the water bath, and a transmission disc is fixed on the outside of the screw. The upper end of the mixing barrel is installed on the fixed pipe.

The wire extruder for rice noodle production can make the texture of the rice noodle raw material more uniform, avoid the adhesion of rice noodles to the mixing barrel, improve the quality of rice noodles, and produce rice noodles of different diameters.

Therefore, in view of the above situation, it is urgent to develop a chemical fiber production extruder with a fast cooling speed and automatic winding of the filamentary material to overcome the shortcomings in current practical applications and meet current needs.
