[0023] The printing paper process is as follows:

[0024] The PLC controller 20 on the outer surface of the mounting frame 2 controls the work of the lifting motor 7, the transmission roller driving motor 6, the two rotating roller driving motors 11, the two lead screw driving motors 16 and the electric push rod 23 respectively.

[0025] The wrapping paper wound on the paper winding roller 21 outside the end part of the machine tool 1 is pulled out and then laid on the moving belt 3 on the surface of the machine tool 1. The PLC controller 20 controls the work of the transmission roller driving motor 6 to drive the movement of the transmission roller 4 at the end part of the machine tool 1, and then the adjacent two transmission rollers 4 are connected through the staggered transmission belt 5, thereby driving the movement of the plurality of transmission rollers 4, so that the moving belt 3 does a circulating rolling process on the surface of the machine tool 1, and the wrapping paper is transported forward from the end part of the machine tool 1, and passes through the bottom of the mounting frame 2 during the movement process.

[0026] When the wrapping paper reaches the bottom of the lifting plate 8, the lifting motor 7 can be operated at this time to drive the lifting plate 8 to move downward, so that the printing roller 9 and the wetting roller 10 are in contact with the surface of the wrapping paper. The two rotating roller driving motors 11 drive the printing roller 9 and the wetting roller 10 to rotate and roll at the front and rear ends of the lifting plate 8. The ink tank 18 and the wetting tank 19 are respectively connected to the ink and wetting solution pipes, and then the ink and wetting solution are respectively applied to the printing roller 9 and the wetting roller 10 by the arc-shaped brushes 26. When the ink and wetting solution on the printing roller 9 and the wetting roller 10 are insufficient at local positions, the two lead screw driving motors 16 on the lifting plate 8 can be operated to drive the first lead screw 12 and the second lead screw 13 to rotate, and the lead screw nut sliding block A 14 and the lead screw nut sliding block B 15 move horizontally under the action of the lead screw transmission, so that the two arc-shaped brushes 26 can move horizontally, and the ink or wetting solution can be applied to different longitudinal positions of the printing roller 9 and the wetting roller 10.

The surface of the wetting roller 10 is a sponge, and the wetting solution at the wetting roller 10 is used to clean and soak the wrapping paper, so as to avoid paper deformation and facilitate ink printing on the wrapping paper. The wrapping paper surface is pressed by the wetting solution roller and then printed by the printing roller 9 to leave ink marks on the paper surface.

[0027] After the paper is printed and dried by the printing roller 9, it is pushed forward along the moving belt 3. The electric push rod 23 controls the downward movement of the guide roller lifting frame 24, so that the plurality of serially connected guide rollers 25 can be in contact with the surface of the paper, and the paper can be kept flat during the pushing process along the moving belt 3.

[0028] After the paper is pulled out from the paper roller 21, it passes through the wetting roller 10 and the printing roller 9 in sequence to complete the printing process.

[0029] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
