[0002] In the field of traditional packaging machines, as one of the key components, the coding device is responsible for marking important information such as production date, batch number, and production unit on product packages. However, in the design of traditional coding devices, in order to make the character mold exactly correspond to the feeding path, the character mold base for installing the character mold is often fixed on the back side of the fixed feeding guide rail and the coding working surface is set on the feeding path. This layout results in that when the character mold needs to be replaced, not only the character mold base itself needs to be disassembled, but also the driving motor, transmission mechanism, and even part of the support structure must be disassembled together. This complex disassembly process not only takes a long time, but also requires professional equipment repair personnel to operate, which seriously affects the coding efficiency of the packaging machine. Therefore, it is necessary to solve the above technical problems. Summary of the Invention
