[0033] Embodiment two: please refer to Figures 6-7 , and in combination with embodiment one, it is further obtained that the processing frame 3 is further provided with the auxiliary dust removal mechanism 7 for adsorbing the dust on both sides of the inner liner paper 11 to be leveled, and the auxiliary dust removal mechanism 7 comprises the dust collector 71 arranged outside the processing frame 3, the dust collector 71 is provided with the connecting pipe 72 at the output end, the connecting pipe 72 is provided with the connecting pipe 73 away from the dust collector 71, and the connecting pipe 73 is provided with the dust adsorption suction head 74 close to the inner liner paper 11.

[0035] In the actual operation process: first, open the connecting door 22, and wind the inner liner paper 11 to be processed on the plurality of conveying rollers 4.

[0036] Then, in order to ensure the flattening of the inner liner paper 11, the tension of the inner liner paper 11 needs to be adjusted.
