While the stationary type mainly plays a role of adsorbing the weight of the material. The safety type is that 8 vacuum suction nozzles are arranged on each group of fan-shaped blocks and are respectively arranged on two fixed sides, 4 vacuum suction nozzles are arranged on each side, the front ends of the safety type vacuum suction nozzles are provided with one-way valves, the one-way valves are opened when the vacuum suction nozzles suck materials, and the safety type vacuum suction nozzles are closed when the materials are not sucked. Because the width of the material is different, a one-way valve is required to be added, otherwise, the vacuum is broken and the material is dropped. The safety mode is controlled by 5 groups of vacuum generators, the first sector is independently controlled, the second sector and the ninth sector, the third sector and the fourth sector, the fifth sector and the sixth sector, and the seventh sector and the eighth sector are respectively controlled by one group of vacuum generators. The size of the suction force of the safe vacuum suction nozzle is also controlled by a pressure regulating valve, the pressure is regulated according to different material thicknesses, and the two sides of the material are ensured not to fall off and have no bubbles.
