[0001] This utility model relates to the field of bottle preform processing technology, and in particular to a device for precise addition and mixing of color oil. Background Technology

[0002] When producing colored bottle preforms, workers add color oil to the mixer and mix the color oil evenly with the bottle preform raw materials before proceeding to the next step of processing.

[0003] A search revealed that prior art CN219820341U discloses a color oil addition device for bottle preform processing, comprising a color oil addition tube, a color oil pipe, a straight pipe, and a sealing component. An outwardly extending arc-shaped plate is fixedly installed on the lower part of the outer end face of the color oil addition tube.
