Each group of fan-shaped blocks is provided with 16 vacuum suction nozzles, and the vacuum suction nozzles are divided into two functions: fixed and secure. The vacuum suction nozzle is controlled by the vacuum generator, and the vacuum generator has vacuum breaking property, namely one vacuum suction nozzle leaks air, and the whole branch circuit loses the adsorption function property, so the vacuum suction nozzle is divided into a fixed type and a safe type. The fixed type is that 72 vacuum suction nozzles on 9 groups of fan blocks are controlled by 4 vacuum generators, because the arrangement width of 8 vacuum suction nozzles in each group is smaller than the minimum width of an inner liner, the vacuum suction nozzles firmly adsorb the carcass part composite component transferred by the carcass drum device 4 through the vacuumizing function of the vacuum generators, the first fan block is positioned at the uppermost position and controlled by one vacuum generator due to different material gravity, the second fan block and the ninth fan block positioned at two sides of the first fan block are controlled by one group of vacuum generators, and the third fan block, the fourth fan block, the fifth fan block and the sixth fan block, the seventh fan block and the eighth fan block are respectively arranged below the second fan block and the ninth fan block and are independently controlled by two groups of vacuum generators. The pressure through adjusting main gas circuit can be used for adjusting the size of vacuum generator adsorption affinity, and pressure can not be too big, also can not be too little, adjusts according to material thickness, because pressure too big can lead to the vacuum nozzle to suck the bubble with the material, and pressure too little can lead to the material to inhale not to live and fall the material, causes the material fold. While the stationary type mainly plays a role in the weight of the adsorption material. The safety type vacuum suction nozzle is characterized in that 8 vacuum suction nozzles are arranged on each group of fan-shaped blocks and are respectively arranged on two sides of a fixed type, 4 vacuum suction nozzles are arranged on each side, a one-way valve is arranged at the front end of each safety type vacuum suction nozzle, and the one-way valve is used for opening when the vacuum suction nozzle sucks materials, and is in a closed state when the vacuum suction nozzle does not suck the materials. Because the widths of the materials are different, a one-way valve is required to be added, or the vacuum is broken to drop the materials. The safety is controlled by 5 groups of vacuum generators, the first sector is controlled independently, the second sector and the ninth sector, the third sector and the fourth sector, the fifth sector and the sixth sector, the seventh sector and the eighth sector are controlled by one group of vacuum generators respectively. The suction force of the safety vacuum suction nozzle is also controlled by a pressure regulating valve, and the pressure is regulated according to different thicknesses of materials, so that the two sides of the materials are ensured not to fall off or generate bubbles.
