The folded part will enter the paper limiting end 8 below, and with the cooperation of the two connecting rollers 6, it will continue to be folded and transported to the material receiving warning mechanism 11. After continuous processing, the number of sheets of paper in the material receiving warning mechanism 11 gradually increases. When a certain value is collected, the material receiving warning mechanism 11 will trigger an alarm to remind the staff that the collection is full and to transfer it in time, so as to realize the positioning of the paper before folding, avoid deviation, affect the folding quality, and then realize the collection of the folded paper. After collecting a certain value, it is warned to improve practicality. By starting the second motor 408, the bidirectional screw rod 402 is driven to rotate, so that the two slide bars 404 slide on the two fixed columns 403, and move towards or away from each other, so as to adjust the distance between the two slide bars 404. When the two slide bars 404 move away from each other, the two L-shaped rods 405, the fixed rod 406 and the positioning plate 407 are driven to move accordingly. According to the width adjustment of the printed paper, the two positioning plates 407 are adapted thereto. By folding the paper and dropping it on the guide plate 1101, the guide plate 1101 is guided to slide onto the support plate 1104. As the number of folded papers on the support plate 1104 increases, the support plate 1104 is driven downward by its weight and the spring 1103 is compressed. The stability of the support plate 1104 can be improved by setting the number and orientation of the springs 1103. When the support plate 1104 moves downward, the rectangular rod 1106 is driven to slide in the rectangular slot 1105, and the rectangular slot 1105 is pressed on the switch of the controller 1108, triggering the alarm 1109 to alert the staff.
