secondly, a bottle blank conveying procedure, wherein the bottle blanks are conveyed to a distributing disc (22) along a conveying rail (21) and are conveyed to a feeding station at intervals under the driving of the distributing disc (22);

thirdly, a feeding process, wherein the clamping mechanism (42) is driven by the rotating mechanism (41) to rotate to a feeding station, the handle clamping piece (422) and the bottle blank clamping piece (423) respectively clamp a handle and a bottle blank at the feeding station, and meanwhile, the translation mechanism (12) loosens the clamping of the handle;

fourthly, a handle preheating procedure, wherein the clamping mechanism (42) clamps the handle and the bottle blank to continue rotating under the driving of the rotating mechanism (41), the bottle blank rotates to pass through the preheating device (5), and the preheating device (5) preheats the handle while walking;

fifthly, a feeding procedure, namely, the preheated handle and the preheated bottle blank rotate to a feeding station along with the clamping mechanism (42), and the pushing mechanism (32) positioned at the feeding station pushes the clamping mechanism (42) and the clamped handle and the bottle blank to enter the bottle blowing mold mechanism (31);

a bottle blowing process, wherein a left mold and a right mold of a bottle blowing mold mechanism (31) are closed, a bottle blank clamping piece (423) loosens the clamping of the bottle blank after the closing, and the bottle blowing mold mechanism (31) starts to blow the bottle blank;

seventhly, a discharging process, namely opening the left die and the right die after blowing molding is finished, continuously clamping the handle by the handle clamping piece (422), supporting the handle together with the molded bottle body, and withdrawing the bottle blowing die mechanism (31) under the driving of the pushing mechanism (32).
