[0042] During normal material loading, the curtain fabric between the mobile curtain fabric unwinding device 1 and the curtain fabric conveying device 4 forms a material pocket, and the photoelectric switch 8 is used to detect the size of the material pocket. When the front material roll is exhausted, the position detection sensor 3 detects the front material head and sends a material exhaustion signal to the controller. After receiving the material exhaustion signal, the controller controls the curtain fabric conveying device 4 to stop conveying the curtain fabric, and at the same time controls the variable frequency motor 13 to drive the roller chain transmission mechanism 12 to work, and move the curtain fabric unwinding trolley out of the unwinding station. After the new material roll is installed on the I-shaped wheel curtain fabric roll 111, the mobile curtain fabric unwinding device 1 is pushed along the track to reach the unwinding station, and the lining fabric head is wound around the lining fabric I-shaped wheel 112. The controller controls the cylinder of the pneumatic mechanism 53 in the transmission device 5 to extend, so that the gear mechanism tilts. After the driven wheel 513 meshes with the gear 1121 of the lining cloth I-wheel 112, the controller starts the motor 52, the driving wheel 511 moves, and the driven wheel 513 moves through the belt 512, and the lining cloth I-wheel 112 moves to guide the curtain fabric. At the same time, the controller controls the pressing driver 24 of the automatic grasping pressing device 2 to work, pushes out the push rod 25, and sucks the new material head through the suction cup set on the back of the pressing head 22. Then, the controller controls the rotating mechanism 21 to rotate, drive the pressing head 22 to rotate to the pressing point, so that the pressing head 22 faces the pressing plate 23, and the pressing driver 24 drives the pressing head 22 to move forward through the push rod 25, so that the new material head and the previous material head are tightly pressed together. After being corrected by the correction device 7, the cord is pressed onto the conveying surface of the cord conveying device 4 by the feeding pressure roller 6, the controller controls the movement of the cord conveying device 4, and the cord conveying device 1 conveys the cord to the carcass bonding position for fully automatic carcass cord bonding, completing automatic cord feeding.

[0043] The automatic cord feeding system provided by the present invention can realize automatic feeding of carcass cords, with accurate overlapping positioning and reliable conveying drive, without the need for manual intervention, thereby improving work efficiency and finished product quality and shortening the material change cycle.
