[0029] The tensioning mechanism 2 includes a tensioning roller 201, a servo motor 202, a first bracket 203, a screw rod 204, a driving block 205, a roller 206, a second bracket 207, a guide sleeve 208, a guide rod 209 and a limit ring 2010;

Then, the non-woven fabric body 3 enters under the melt-blown die head 4, and the raw material conveyor 5 melts the raw material The material is introduced into the meltblowing die head 4, and high-speed hot air circulates in the hot air channel 8.
