By providing the device body 1, the device body 1 serves as the installation main body of the present utility model. The drafting rollers 2 are rotatably connected inside the device body 1. The non-woven fabric is on the top of the support plate 3. By the rotation of the drafting rollers 2 inside the device body 1, the non-woven fabric is driven to move on the support plate 3. At the same time, it is cooperated with high-speed air flow to drive the non-woven fabric to move. When the non-woven fabric is drafted, it is impossible to ensure that the fibers are flat, so the fibers are prone to be uneven. By providing the leveling mechanism 4, by using the leveling mechanism 4 on the non-woven fabric, the non-woven fabric is moved in the length direction of the drafting rollers 2, so that the fibers are moved in the length direction of the drafting rollers 2, ensuring the uniformity of the fibers in the length direction of the non-woven fabric. The produced non-woven fabric has a flat surface and a balanced color, improving the production quality of the non-woven fabric.

[0022] In an embodiment of the present utility model, the leveling mechanism 4 includes a telescopic motor 41, a telescopic mechanism 42, a support guide rail 43, and a flattening plate 44.

Both ends of the flattening plate 44 slide in the support guide rail 43, improving the stability of the flattening plate 44.

[0023] In an embodiment of the present utility model, flattening protrusions 5 extending towards the support plate 3 are arranged at intervals on the bottom of the flattening plate 44, and both ends of the flattening plate 44 are arranged along the length direction of the drafting rollers 2. By providing the flattening protrusions 5, the friction force at the bottom of the flattening plate 44 is increased, making the effect of the flattening plate 44 in leveling the fibers better.

[0027] In an embodiment of the present utility model, the two ends of the device body 1 are respectively provided with a feed hole 9 and a discharge hole 10. By setting the feed hole 9 and the discharge hole 10, the non-woven fabric enters the device body 1 from one end of the feed hole 9, then enters onto the support plate 3, and then enters below the drafting roller 2 for drafting processing. After the drafting processing, it is discharged from the discharge hole 10.
