The invention relates to the technical field of bubble blowing toy production, in particular to a bubble blowing bar automatic filling device for bubble blowing toy production. The bubble blowing barautomatic filling device comprises a transmission mechanism, a sorting mechanism and a screening mechanism; the screening mechanism comprises a receiving component, a reversing component and an outputcomponent, the receiving component intermittently communicates with the sorting mechanism, the output component is arranged below the receiving component, the reversing component comprises a pushingportion and a reversing portion which are arranged on the two sides of the receiving component, and reverse bubble blowing bars are pushed by the pushing portion to the reversing portion in the rotation and lifting process of the receiving component to be reversed to enter the output component to be output; and the sorting mechanism is used for gradually sorting the bubble blowing bars one by one,the bubble blowing bars are filled into a bubble blowing bottle through the screening mechanism in the vertical direction, the screening mechanism is used in cooperation to achieve direction screening and automatic reversing of the bubble blowing bars, and one-to-one filling of the bubble blowing bars into the bubble blowing bottle in the specific direction is achieved.
