The invention discloses a pet basin automatic production line. The pet basin automatic production line comprises a control device, a frame, a previous procedure production device and a later procedureproduction device, wherein the previous procedure production device comprises a stacking mechanism, a first feeding mechanism arranged above the stacking mechanism, a sheet positioning mechanism, a sheet detecting mechanism arranged between the first feeding mechanism and the sheet mechanism, and an abnormal sheet receiving mechanism, which are arranged in sequence; and the later procedure production device comprises a stretching mechanism, a trimming mechanism, an edge rolling mechanism, and a second feeding mechanism for conveying sheets among the sheet positioning mechanism, the stretchingmechanism, the trimming mechanism and the edge rolling mechanism in sequence, which are arranged in sequence. Through the structure, the pet basin automatic production line realizes automatic production of pet basins, reduces the labor intensity of workers and the occupational injury occurrence probability, and meanwhile, improves the enterprise production efficiency.
