A fabric expander 6 is provided after each of the first unwinding roller 2, the second unwinding roller 3, and the third unwinding roller 4.

[0021] The unwinding device is connected to a hot pressing device, which includes three sets of heating rollers 7. The temperature of each set of heating rollers 7 can be independently adjusted by the control system to adapt to the hot pressing requirements of different materials.

[0028] A screw manual adjustment limiting device 18 is further arranged below the winding roller.

[0029] Working principle:

[0030] The material is unwound on the unwinding frame through three unwinding rollers arranged in sequence and raised, and the magnetic powder tension controller accurately controls the tension.

[0031] The unwound material enters the hot pressing device, and three groups of heating rollers independently adjust the temperature according to the instructions of the control system, so as to realize accurate hot pressing.

[0032] The material after hot pressing is first air-cooled by the cooling fan in the air oven, and then water-cooled by the water-cooling assembly, so as to realize rapid and uniform cooling.

[0033] The cooled material is respectively wound with protective film paper and finished product, and the winding roller is connected with the winding frame through a linear bearing taper sleeve limiting block, so as to ensure the stability and accuracy of winding.
