Description

Technical Field

[0001] This utility model relates to the field of printing equipment, specifically to an integrated anti-counterfeiting certificate printing device. Background Technology

[0002] Anti-counterfeiting printing is a comprehensive anti-counterfeiting technology and a branch of special printing. It refers to using printing methods to prevent unauthorized imitation, copying, or forgery. Anti-counterfeiting certificates generally use four-color printing plus spot color printing or gravure printing. Combining four-color printing and gravure printing is a very effective anti-counterfeiting and high-quality printing strategy. Important information on certificates or documents (such as logos, anti-counterfeiting patterns, and key text) is printed using gravure printing, while background patterns, color images, and gradient effects are achieved through four-color printing.

[0003] Printing inks are mainly composed of pigments, binders (resins), fillers, additives, and solvents. Pigments and fillers, with their relatively high density, tend to settle in the ink. During the printing process, as ink settles in the ink trough, the upper layer of ink is thinner than the lower layer, resulting in uneven color and concentration, which affects the quality of the printed product. Therefore, those skilled in the art have provided an integrated anti-counterfeiting certificate printing device to solve the problems mentioned in the background art. Utility Model Content

[0030] Please see Figures 1-7This embodiment provides an integrated anti-counterfeiting certificate printing device, including a gravure printing module 1 and a four-color printing module 2. The four-color printing module 2 is located on one side of the gravure printing module 1. The gravure printing module 1 includes a support plate 11, with support rollers 12 rotatably connected to both sides of the support plate 11. A pressure roller 13, a printing plate roller 14, and an inking roller 15 are installed sequentially from top to bottom between the support plates 11. An ink trough 16 is installed between the support plates 11 below the inking roller 15. Paper enters between the pressure roller 13 and the printing plate roller 14 through the support roller 12. The pressure roller 13 presses the paper into the groove on the printing plate roller 14 to form a gravure print. The inking roller 15 rotates and contacts the printing plate roller 14, applying the ink from the ink trough 16 to the outside of the printing plate roller 14 and the inside of the groove. The paper is pressed into the groove, thus copying the ink onto the paper.

[0031] A reciprocating screw 161 is rotatably connected inside the ink tank 16. An agitator 163 is located outside the reciprocating screw 161. The agitator 163 includes a movable seat 1631 through which the reciprocating screw 161 passes. A push plate 1632 is fixedly connected below the movable seat 1631. A stirring paddle 1633 is slidably connected to both sides of the movable seat 1631. A gear 1634 is fixedly connected to one side of the stirring paddle 1633. A rack 164 is fixedly connected inside the ink tank 16 below the gear 1634. The rotation of the reciprocating screw 161 drives the agitator 163 to move back and forth inside the ink tank 16. The gear 1634 moves along with the movable seat 1631. As the gear 1634 moves, it passes over the rack 164, causing the gear 1634 to rotate. The rotation of the gear 1634 agitates the ink inside the ink tank 16, preventing sedimentation.

[0032] In this embodiment, specifically, a motor 3 is fixedly installed on one side of the support plate 11, and the printing plate roller 14 is fixedly connected to the motor 3 on one side. A gear 2 141 is fixedly connected to one side of the printing plate roller 14, a gear 1 131 is fixedly connected to one side of the pressure roller 13, and a gear 3 151 is fixedly connected to one side of the inking roller 15. Gear 2 141 meshes with gear 1 131 and gear 3 151. The motor 3 starts and drives the printing plate roller 14 to rotate. The rotation of the printing plate roller 14 drives gear 1 131 and gear 3 151 to rotate through gear 2 141. The rotation of gear 1 131 and gear 3 151 drives the pressure roller 13 and the inking roller 15 to rotate.

[0033] In this embodiment, specifically, a second sprocket 162 is fixedly connected to one side of the reciprocating screw 161, and a first sprocket 152 is fixedly connected to the other side of the ink roller 15 below the motor 3. A chain is sleeved on the outer side of both the second sprocket 162 and the first sprocket 152. The rotation of the ink roller 15 drives the first sprocket 152 to rotate, and the rotation of the first sprocket 152 drives the second sprocket 162 to rotate via the chain. The second sprocket 162 then drives the reciprocating screw 161 to rotate, causing the stirring assembly 163 to move back and forth.

[0034] In this embodiment, a scraper 17 is specifically installed below the support roller 12, with one end of the scraper 17 contacting the outer surface of the printing plate roller 14. The scraper 17 removes excess ink from the outer side of the printing plate roller 14.

[0035] In this embodiment, specifically, a rack 164 is also fixedly connected inside the ink trough 16 above the gear 4 1634. A connecting rod 1635 is fixedly connected to one side of the gear 4 1634. The connecting rod 1635 is made of iron. Limiting plates 165 are fixedly connected to both sides inside the ink trough 16. A sliding groove 1651 is provided inside the limiting plate 165. One end of the connecting rod 1635 is located inside the sliding groove 1651. A magnet 166 is fixedly connected above one end of the limiting plate 165.

[0036] In this embodiment, specifically, the cross-section of the slide groove 1651 is annular. When the gear 4 1634 moves, it also drives the connecting rod 1635 to move together. The connecting rod 1635 moves below inside the slide groove 1651. Figure 5 (From left to right in the middle viewpoint), when the connecting rod 1635 moves to one end of the limiting plate 165, it is sucked into the upper part of the slide groove 1651 by the magnet 166, and moves in the upper part of the slide groove 1651 during the return. Figure 5 (From a medium perspective, right to left), gear 1634 meshes with the upper rack 164, thus keeping the agitator 1633 rotating clockwise at all times. Figure 5 From the perspective of the ink trough 16, the ink inside is constantly stirred upwards.
