By arranging the connecting rod 17, the first cross plate 19 can be made to move upward or downward, and further the upper pressing hollow roller 8 can be made to move upward or downward, which can meet the extrusion requirements for non-woven fabrics of different thicknesses. After the distance between the upper pressing hollow roller 8 and the lower pressing roller 5 is adjusted, the first motor 3 and the second motor 10 are started to rotate the upper pressing hollow roller 8 and the lower pressing roller 5, so that the non-woven fabric to be processed passes through the upper pressing hollow roller 8 and the lower pressing roller 5 for extrusion.

By arranging the air injection rod 25, the abutting block 26 and the spring 24, the abutting block 26, the air injection rod 25 and the air injection plug 23 can be made to move up and down. During the up and down movement of the air injection plug 23, since one-way valves are arranged in both the air inlet pipe 20 and the air outlet pipe 11, the heated air in the heating box 13 is sucked into the air injection box 12 through the air inlet pipe 20 and then is extruded into the upper pressing hollow roller 8 through the air outlet pipe 11 and the rotating tube 27, and finally is sprayed out through the air outlet holes 9 onto the non-woven fabric, so that the hot pressing forming effect can be improved during the extrusion process.
