Blow-drying machine for extruder production line

The invention discloses a blow-drying machine for an extruder production line. The blow-drying machine for the extruder production line comprises a water tank, wherein a water outlet pipe is installedon the lower surface of the water tank; a water outlet valve is installed at the middle part of the water outlet pipe; and a control switch is installed on the front side surface of the water tank. The blow-drying machine for the extruder production line is simple in structure; wiping pretreatment is carried out on water on the side surface of a material pipe through a water scraping box, so thatthe attachment amount of the water on the side surface of the material pipe is reduced; the radial thickness of elastic cotton can be adjusted through the extrusion of a push ring, so that the adequate contact of the elastic cotton and the material pipe is facilitated, and the blow-drying machine is applicable to material pipes with different diameters; the material pipe is driven to vibrate through the movement of a vibr
