[0028] In the present invention, when the printing pattern does not cover the entire plate cylinder 3, a blank space will be formed on the printing material during the printing process, and it is necessary to control the movement of the printing material through the impression cylinder 5 so that the pattern is printed on the blank space; the printing material enters from the rear of the vertical plate 2, and the plate cylinder 3 rotates, so that the ink is transferred from the plate cylinder 3 to the rubber cylinder 4, and then the motor 9 is started through the central control box 6. The operation of the motor 9 drives the intermittent adjustment mechanism 7 to work, so that the impression cylinder 5 rotates intermittently, thereby realizing the control of the paper feeding and retraction of the printing material; the intermittent adjustment mechanism 7 makes the electric motor 9 rotate intermittently, so as to realize the control of the paper feeding and retraction of the printing material. The machine 9 can control the feeding and retraction of the printing material without the need for frequent forward and reverse rotation, thereby reducing the probability of equipment failure caused by frequent forward and reverse rotation of the motor 9, ensuring the progress and efficiency of printing, and improving the practicality of the equipment; when the printing material is pressed by the rubber roller 4 and the impression roller 5, the graphic information will be transferred to the printing material, but due to the different patterns on different printing plates, the ink transferred to the printing material is uneven. The position of the light-curing lamp 10 is changed by the adjustable light-curing mechanism 8 to ensure that the position of the light-curing lamp 10 is located at a location with more ink in the printing pattern, thereby further improving the printing quality.

[0029] The intermittent adjustment mechanism 7 includes a support plate 71, an upper driving gear 73, a lower driven gear 74, an upper incomplete gear 75, a lower incomplete gear 76 and an embossing roller driving gear 77.
