The invention discloses a box strip traceability code association device and method, and relates to the technical field of packaging machinery, and the box strip traceability code association device comprises a computer, a conveying mechanism, and a first code printer, a first code reader, a rejecting mechanism, a second code reader, a second code printer and a third code reader which are sequentially arranged along the conveying direction of the conveying mechanism; the first code reader can read the package traceability codes on the small packages, the small packages with the unqualified package traceability codes can be removed from the conveying mechanism in cooperation with the removing mechanism, it is strictly guaranteed that the small packages with the unqualified package traceability codes cannot flow to the downstream, and the second code reader can recognize the package traceability codes on the small packages. The third code reader can identify the strip traceability code on the strip package packaging paper, and the computer can be associated with the complete package traceability code read by the second code reader and the strip traceability code read by the third code reader, so that the technical effect of reducing the outflow rate of incomplete traceability code products is achieved.
