inside of the shunt tube 205 is directly shunted and conveyed into each first atomizer 207, then the water entering the inside of each first atomizer 207 is directly atomized and sprayed on the outer wall of the multilayer fluid, so as to achieve the same effect as described above, when the multilayer fluid is output from the output end of the discharge tube 104 for a certain length, the cooperation of the PLC and the blow molding machine is directly utilized at this time, the output of the multilayer fluid from the output end of the discharge tube 104 is stopped, the water pump 214 and the air conditioning valve 223 are closed, and then the cooperation of other components of the blow molding machine is utilized to perform the post blow molding operation.
