Among them, a paper pressing mechanism is provided on the front edge of the paper feeding unit. The paper pressing mechanism includes two fixing plates, and a front baffle is fixedly installed on one side of the fixing plate. A cylinder is fixedly installed on one side of the fixing plate, and the output end of the cylinder is fixedly connected with a connecting block. A pressing wheel is fixedly installed at the bottom of the connecting block. A front edge air suction box is provided below the two pressing wheels.

[0007] Preferably, a cardboard is arranged between the front edge air suction box and the pressing wheel.

[0008] Preferably, the front baffle is fixedly installed on one side of the fixing plate by screws, and the bottom of the front baffle extends below the fixing plate.

[0009] Preferably, the bottom of the front baffle extends to one side of the cardboard.

[0010] Preferably, a pressing wheel seat is fixedly installed at the bottom of the connecting block, and the pressing wheel is rotatably installed on the pressing wheel seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] After the paper pressing mechanism is provided, it is convenient for the cardboard to be conveyed smoothly, which is beneficial to the flatness, beauty and accuracy of paper feeding, and improves the production efficiency and production quality. Brief Description of the Drawings

[0016] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figure 1-2 , the present utility model provides a technical solution: a leading edge paper pressing mechanism for the paper feeding part of a carton printing and forming production line, including a paper feeding unit, a printing unit, a slotting unit and a die-cutting unit. Among them, a paper pressing mechanism is provided on the leading edge of the paper feeding unit. The paper pressing mechanism includes two fixed plates 1, and a front baffle 5 is fixedly installed on one side of the fixed plate 1. A cylinder 2 is fixedly installed on one side of the fixed plate 1, and the output end of the cylinder 2 is fixedly connected to a connecting block 3. A pressing wheel 4 is fixedly installed at the bottom of the connecting block 3. A leading edge air suction box 7 is provided below the two pressing wheels 4.

[0018] In the present utility model, a cardboard 6 is provided between the leading edge air suction box 7 and the pressing wheel 4.

[0019] In the present utility model, the front baffle 5 is fixedly installed on one side of the fixed plate 1 by screws, and the bottom of the front baffle 5 extends below the fixed plate 1.

[0020] In the present utility model, the bottom of the front baffle 5 extends to one side of the cardboard 6.

[0021] In the present utility model, a pressing wheel seat is fixedly installed at the bottom of the connecting block 3, and the pressing wheel 4 is rotatably installed on the pressing wheel seat.

[0022] The working principle of the present utility model: The cylinder 2 is fixed on the fixed plate 1, the fixed plate 1 is connected to the front baffle 5, and the connecting block 3 is fixed to the output end of the cylinder 2. When the cylinder 2 makes a lifting motion, the connecting block 3 drives the pressing wheel 4 to lift and lower with the cylinder 2.
