[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1 , the present utility model provides a technical solution: a mechanism for independently adjusting the paper passing gap of the lower corner cutting wheel in the carton printing and forming section, including a paper feeding unit, a printing unit, a forming unit and a die-cutting unit. Among them, the forming unit is provided with a mechanism for independently adjusting the paper passing gap of the lower corner cutting wheel. The mechanism for independently adjusting the paper passing gap of the lower corner cutting wheel includes a pre-pressing lower wheel 5 and a pre-pressing upper wheel 7, and the pre-pressing lower wheel 5 and the pre-pressing upper wheel 7 are arranged correspondingly. A adjusting motor 1 is arranged below the pre-pressing lower wheel 5, and the output end of the adjusting motor 1 is connected with a cross steering gear 2, and the cross steering gear 2 is connected with a lifting lead screw 3;

[0016] One end of a swing rod 4 is connected to the wheel core of the pre-pressing lower wheel 5, and the bottom of the swing rod 4 is connected with the lifting lead screw 3.

[0017] In the present utility model, a paperboard 6 is arranged between the pre-pressing lower wheel 5 and the pre-pressing upper wheel 7.

[0018] In the present utility model, a fulcrum is arranged on one side of the pre-pressing lower wheel 5, and the end of the swing rod 4 away from the pre-pressing lower wheel 5 is rotatably installed on the fulcrum.
