The goods are shaped under the cooperation of the pressing plate 2 and the shaping part 10. The cylinder guide rod 5 moves downward synchronously with the pressing plate 2. After the cylinder guide rod 5 moves to the top and is flush with the photoelectric switch 60 (i.e., reaches a preset height), the photoelectric switch 60 is closed, and the main driving shaft 41 of the shaping cylinder 4 stops pressing down. At the same time, the time relay is closed, and the main driving shaft 41 of the shaping cylinder 4 stops moving within the preset time of the time relay to continuously compress the goods. After the preset time ends, the main driving shaft 41 of the shaping cylinder 4 retracts to reset. The driving part 7 drives the bottom plate 3 to be withdrawn along the first direction, and the compressed material falls on the belt conveyor 8 below. The belt conveyor 8 can transport the compressed goods to the designated location, thereby reducing the consumption of human resources and keeping the appearance size of the compressed goods consistent.
