The invention relates to the field of printer material rolling shaft machining, in particular to a film bonding device of a printer material rolling shaft. The film bonding device of the printer material rolling shaft comprises a bonding operation platform, a material shifting assembly, a containing jig, a first power assembly and a second power assembly. The material shifting assembly is arrangedon the top of the bonding operation platform. The containing jig is used for supporting a material rolling shaft. The first power assembly is used for bonding film to the two ends of the material rolling shaft. The second power assembly is used for bonding film to the middle segment of the material rolling shaft. The first power assembly and the second power assembly are symmetrically arranged onone side of the bonding operation platform. A supporting base is arranged at an output end of the material shifting assembly. The containing jig can be rotationally arranged in the supporting base. Aglue spray assembly is arranged above the bonding operation platform. The first power assembly and the second power assembly are the same in structure. The first power assembly comprises a reversingcomponent, a stamping cutting component and an attachment component. The stamping cutting component and the attachment component are symmetrically arranged at the bottom of the reversing component. The film bonding device of the printer material rolling shaft can automatically carry out film bonding work on the material rolling shaft, material waste caused by wrong manual bonding is avoided, and the yield is increased.
