[0022] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a screw extrusion device includes an extrusion component 1 and a cooling component 2, the extrusion component includes a first bracket 11, the first bracket is provided with an extruder 12, the cooling component includes a second bracket 20, the second bracket is provided with a puller 21 and a cooling zone 22, the puller is correspondingly arranged behind the extruder for pulling out the extruded material, and the cooling zone is arranged before or after the puller for cooling the material. The material extruded by the extruder is pulled out by the puller and cooled in the cooling zone, and the cooling zone can be cooled by spraying water or the like.

[0023] In this embodiment, as shown in the figure, the cooling zone is provided with a plurality of transmission rollers 41, and also includes a nozzle 42 connected to a water source, the nozzle being relatively arranged above the transmission rollers to cool the core wire passing through.

[0024] In this embodiment, as shown in the figure, the puller includes a plurality of transmission frames 51, which are arranged at intervals, and the transmission frames are provided with transmission wheels 52. Each transmission frame is provided with at least two transmission wheels, and a through groove for the core wire to pass through is formed between the two transmission wheels.

[0025] In this embodiment, as shown in the figure, the nozzles are arranged between adjacent transmission frames to further reduce the temperature.

[0026] In this embodiment, as shown in the figure, at least one transmission wheel on the transmission frame is connected to a power source 6. The power source can be a motor, which drives a transmission wheel to rotate (the transmission shaft of the motor can be connected to the core shaft of the transmission wheel, specifically using a coupling connection), thereby driving the core wire forward, and when the transmission wheel rotates, the core wire is driven by friction, and the inner wall of the through groove contacts the outer wall of the core wire.
