Under the action of the small air cylinder 213, the alignment head 218 can be controlled to swing through the side slot 210-1 into the conveying track 225, thereby forming an obstruction in the conveying direction for blocking the passing stacked material and aligning the material.

In this embodiment, the operation process of the small cylinder 213 is controlled by the control system, and the operation process is as follows: the control system controls the movable rod of the small air cylinder 213 to retract, so that the alignment head 218 enters the conveying track 225 and keeps the state, when the first conveying belt 260 drives the stacked materials to enter the fifth conveying unit 210, the front ends of the stacked materials are aligned under the action of the alignment heads 218 on the two sides, and then (according to the conveying speed, the higher the conveying speed is, the shorter the blocking time is, the lower the conveying speed is, the blocking time can be properly prolonged, and under the condition of 10-15 m/s, the contact time of the alignment heads 218 and the stacked materials is smaller than 3s) the control system controls the movable rod of the small air cylinder 213 to extend, so that the alignment head 218 exits the conveying track 225, and the aligned materials are conveyed forwards continuously.

Finally, as shown in fig. 9, a flattening mechanism 4 is disposed at the end of the conveying track 225, and the flattening mechanism 4 is used for providing pressure to the stacked materials to further tightly bond the stacked layers of materials.
