Guide rollers 16 are fixedly connected to the outer circumferential surface of the rotating shaft 15, and a liquid leveling plate 30 is also fixedly connected between the support frames of the middle support frame group 14. A humidification component is fixedly connected to the two support frames of the support frame group 14 near one end of the liquid leveling plate 30.

[0023] The humidification component includes a steam bin 17 and an exhaust pipe 20. The steam bin 17 is fixedly connected to the exhaust pipe 20. A steam chamber 18 is provided in the steam bin 17. An exhaust channel 21 is provided in the exhaust pipe 20. The steam chamber 18 is connected to the exhaust channel 21. A limiting slide groove 22 is provided on the exhaust pipe 20. A steam volume regulating block 23 is slidably connected in the limiting slide groove 22. The steam volume regulating block 23 is used to adjust the size of the exhaust port of the exhaust channel 21.

[0024] It is worth noting that the calendering roller group 12 is a prior art, and a plurality of calendering rollers are arranged in the calendering roller group 12. A steam generator is built into the steam chamber 18, and the steam generator is a prior art. The device has a winding roller outside, and the winding roller is used to drive the polypropylene single and multifilament filter material to be transmitted along the extension direction of the calendering table 11.

[0025] Both ends of the feeding port 13 of the calendering roller group 14 which is rotatably connected to the support frame group 14 fixedly connected to the steam bin 17 are fixedly connected with a fixing ring 27, and an active lever 28 is detachably connected to the outer circumferential surface of the fixing ring 27. The active lever 28 is provided with various specifications. The active lever 28 of different specifications can be used to adjust the displacement of the steam volume regulating block 23, thereby adjusting the steam output in the exhaust channel 21. Passive levers 26 are fixedly connected to both ends of the steam volume regulating block 23 close to the fixing ring 27, and the active lever 28 is used to push the passive lever 26.

[0026] A reset plate 24 is fixedly connected to the side of the steam volume regulating block 23 away from the fixed ring 27, and a reset spring 25 is fixedly connected to the reset plate 24. The end of the reset spring 25 away from the reset plate 24 is fixedly connected to the support frame of the support frame group 14, and the distance between the end of the active lever 28 away from the rotating shaft 15 and the axis of the rotating shaft 15 is greater than the extreme position of the passive lever 26 close to the rotating shaft 15.
