[0002] Fiber fabric calendering device is usually an important equipment used in the fiber fabric processing process to change the appearance, feel and performance of the fabric.

However, fiber fabrics of different thicknesses will be compressed to different degrees under the same pressure, resulting in uneven calendering effect. Some areas may be over-compacted while other areas are not compacted enough. In addition, during the compression process, wrinkles appear on the fabric, and creases will appear on the wrinkled parts after hot pressing, affecting the final appearance quality.

At the same time, the fiber fabric is laid on the first hot pressing roller 3, and the fiber fabric is pressed down by the adjustment mechanism 4. At the same time, the pressure on the fiber fabric is adjusted according to the thickness of the fiber fabric.

[0032] See also Figure 3-4In order to facilitate the adjustment of the pressure on the fiber fabric, the adjustment mechanism 4 in this embodiment includes a cylinder 401, a support frame 402, at least two connecting shafts 403 and a second hot pressing roller 404; the cylinder 401 is assembled on the box body 1, and the output end of the cylinder 401 penetrates and extends into the interior of the box body 1, and the support frame 402 is assembled at the output end of the cylinder 401, so that when the output end of the cylinder 401 is extended or retracted, the support frame 402 is driven to slide up and down inside the box body 1; at least two connecting shafts 403 are arranged below the support frame 402 at intervals along the X-axis direction, and the second hot pressing roller 404 is rotatably connected between the at least two connecting shafts 403.

[0033] In actual use, the output end of the cylinder 401 is controlled to extend and retract according to the thickness of the fiber fabric, thereby driving the support frame 402 to move up and down, so as to adjust the distance between the second hot pressing roller 404 and the first hot pressing roller 3, and at the same time adjust the pressure of the fiber fabric.

[0034] It should be noted that in order to effectively calender the fiber fabric, the preferred number of first hot pressing rollers 3 in this embodiment is four, the number of second hot pressing rollers 404 is two, and a certain gap is retained between at least two first hot pressing rollers 3, and the second hot pressing roller 404 is located directly above the gap.
