After baking, the transmission plate 707 moves the naan into the trolley 4.

[0026] Through the above steps, by sliding the push block 605, the push block 605 is disengaged from the surface of the limiting bead 606, releasing the limiting bead 606. Then, the fixing post 607 is pulled to remove it. Then, the fixing post 607 of the naan mold to be installed is inserted into the push rod 603. Then, the push block 605 is released, and the first spring 604 drives the push block 605 to slide. The push block 605 pushes the limiting bead 606, so that the limiting bead 606 is engaged with the groove of the fixing post 607, completing the replacement. By placing the dough on the conveyor belt 5, the telescopic cylinder 602 is activated. The telescopic cylinder 602 drives the push rod 603 to move. The push rod 603 drives the fixing post 607 to move. The fixing post 607 drives the extrusion plate 608 to move. The extrusion plate 608 drives the extrusion cover 611 to move, extruding the dough.
