DETAILED DESCRIPTION

[0018] The preferred solution is Figures 1 to 2 As shown, a non-woven fabric ironing device includes a frame 1, on which a non-woven fabric unwinding device 2, a non-woven fabric folding structure 3 and a developing line pay-off device 4 are provided. A ironing device 5 is provided at the process rear end of the developing line pay-off device 4. The ironing device 5 includes a heating roller 501 arranged on the frame 1, and a heating element is provided in the heating roller 501; the heating roller 501 is used to heat the developing line in the non-woven fabric interlayer.

[0019] The non-woven fabric unwinding device 2 is used to provide non-woven fabric, the non-woven fabric folding structure 3 is used to fold a single layer of non-woven fabric into a double layer, the developing line unwinding device 4 is used to provide developing line, and the developing line is used to be sandwiched in the double layer of non-woven fabric; the ironing device 5 is used to heat the developing line, and the developing line after heating has a certain viscosity, which is used to stick the developing line in the double layer of non-woven fabric.

[0020] Furthermore, a slide rail 6 is provided on the frame 1, and the slide rail 6 cooperates with the slider 7. The slider 7 is driven up and down by the lifting device 8. A support frame 9 is provided on the slider 7, and a guide roller 10 is provided on the support frame 9. The guide roller 10 is located obliquely below the heating roller 501, and the non-woven fabric passes between the heating roller 501 and the guide roller 10.

[0021] The lifting device 8 is used to control the guide roller 10 to move up and down. Figure 2 As shown, when the guide roller 10 is controlled to move upward, the contact area between the nonwoven fabric and the heating roller 501 is increased, thereby increasing the heating effect of the developing line. Conversely, when the guide roller 10 is controlled to move downward, the contact area between the nonwoven fabric and the heating roller 501 is reduced, thereby reducing the amount of heat received by the developing line.

[0022] Furthermore, the lifting device 8 includes a stepping motor, which drives the screw rod 802 to move through the reduction box 801, and the screw rod 802 is threadedly connected to the slider 7.

[0023] The stepper motor is used to drive the screw rod 802 to rotate, and the screw rod 802 that rotates forward or reverse is used to drive the slider 7 to move up and down.

[0024] Furthermore, a rectangular optical fiber sensor 11 is provided at the process rear end of the heating roller 501 , and the rectangular optical fiber sensor 11 is used to detect whether the developing line is broken.

[0025] When the developing line is intact, the length of the developing line detected by the rectangular fiber optic sensor 11 is constant. If the developing line breaks and melts, the length of the developing line detected by the rectangular fiber optic sensor 11 decreases. The rectangular fiber optic sensor 11 is electrically connected to the input of the controller, and the output of the controller is electrically connected to the stepper motor of the lifting mechanism 8. If a line break occurs, the controller controls the downward movement of the guide roller 10.
