Description

Technical Field

[0001] The present application relates to the field of printing presses, and in particular to a printing device of a printing press. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its operating principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied manually or by the printing press to the areas of the plate where the text and image appear. The ink is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), creating a printed product identical to the printing plate.

[0003] Digital printing is a printing technology that is different from traditional printing methods. It uses digital printing to output digital files directly to printing media using digital printers without the need to make printing plates.

[0004] During the paper box processing process, it is necessary to print on both sides of the unprinted cardboard. However, most of the existing double-sided printing machines require manual flipping of the cardboard for secondary printing, which is time-consuming and labor-intensive, and the manual efficiency is relatively low.

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] An embodiment of the present application discloses a printing device of a printing press.

[0024] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A printing device of a printing press includes a printing component 1, a flip component 2, a base 3 and an auxiliary plate 4.

[0025] Two auxiliary plates 4 are provided, and the two auxiliary plates 4 are fixedly mounted at opposite edges of the top end of the base 3 , and both the base 3 and the auxiliary plates 4 play a supporting role.

[0026] Two printing assemblies 1 are provided, and the two printing assemblies 1 are sequentially placed between the two auxiliary plates 4 along the length direction of the auxiliary plates 4. The printing assembly 1 includes an arch 11, a printer 12, a drive motor 13, a conveyor belt 14, and two rollers 15. The arch 11 is fixedly mounted on the top of the two auxiliary plates 4. The printer 12 is fixedly mounted on the concave end of the arch 11. The drive motor 13 is fixedly mounted on the right end of the right auxiliary plate 4. The rotation axis of the drive motor 13 passes through the right auxiliary plate 4 and is located between the two auxiliary plates 4. The placement direction of the rotation axis of the drive motor 13 is perpendicular to the projection of the placement direction of the auxiliary plates 4 on the horizontal plane. Both rollers 15 are located between the two auxiliary plates 4. One end of the front roller 15 is fixedly connected to the rotation axis of the drive motor 13, and the other end is horizontally connected to the left auxiliary plate 4. The two ends of the rear roller 15 are horizontally connected to the two auxiliary plates 4. The conveyor belt 14 is looped around the outer walls of the two rollers 15. It should be noted that the two rollers 15 move in the same direction, both rotating counterclockwise.

[0027] The flip assembly 2 is located between the two printing assemblies 1. The flip assembly 2 includes a flip motor 21, a support block 22, and two clamping plates 23. The flip motor 21 is fixedly mounted on the right end of the right auxiliary plate 4. The rotating shaft of the flip motor 21 passes through the right auxiliary plate 4 and is located between the two auxiliary plates 4. The placement direction of the rotating shaft of the flip motor 21 is perpendicular to the projection of the placement direction of the auxiliary plates 4 on the horizontal plane. The support block 22 is located between the two auxiliary plates 4. One end of the support block 22 is fixedly connected to the rotating shaft of the flip motor 21, and the other end is horizontally connected to the left auxiliary plate 4. A horizontal slide 221 is provided at the rear end of the support block 22. The two clamping plates 23 are slidably connected to the support block 22 through the slide 221. The facing ends of the two clamping plates 23 are both provided with horizontal receiving grooves 231. The bottom side of the end of the clamping plate 23 facing away from the support block 22 is in an upward inclined shape. Both clamping plates 23 are placed on the conveyor belt 14.

[0028] As can be seen, the two clamping plates 23 are slidably connected to the support block 22 via the slide grooves 221, and can clamp cardboards of different widths. To secure the clamping plates 23, the top of the support block 22 is provided with a locking pin 222, which passes through the top of the support block 22 and abuts against the top of the clamping plates 23.

[0029] The cardboard is first placed on the rear conveyor belt 14 for conveyance. When the cardboard is conveyed to the bottom of the rear printer 12, the rear printer 12 can print on the cardboard surface. After printing is completed, the rear conveyor belt 14 continues to convey the cardboard forward. Because the bottom side of the clamping plate 23 facing away from the support block 22 is inclined upward, the cardboard slides into the receiving slot 231 due to the movement of the conveyor belt 14. When the front end of the cardboard contacts the front groove wall of the receiving slot 231, the flip motor 21 is activated, driving the support block 22 to rotate, which in turn drives the clamping plate 23 to rotate. The clamping plate 23 causes the cardboard to flip. After the cardboard has flipped 180 degrees, the flip motor 21 stops. At this point, the cardboard is conveyed by the front conveyor belt 14 to the bottom of the front printer 12, and the front printer 12 can print on the cardboard surface. It should be noted that only two-thirds of the cardboard length slides into the receiving slot 231.

[0030] In order to enhance the stability of the cardboard during the flipping process, a support plate 232 is fixedly installed on the two clamping plates 23 facing each other. The support plate 232 is located below the receiving groove 231 , and the bottom end of the cardboard abuts against the top end of the support plate 232 .

[0031] In order to prevent the cardboard from shaking during transportation, which may result in incomplete printing by the printer 12, two fixed tubes 5, two telescopic rods 6 and two guide plates 7 are provided on the arch frame 11; the two fixed tubes 5 are horizontally fixedly mounted on the opposite inner walls of the arch frame 11, and a first connecting hole 51 is provided on the fixed tube 5; a telescopic rod 6 is horizontally slidably mounted on a fixed tube 5, and a plurality of second connecting holes 61 are provided on the telescopic rod 6, and the plurality of second connecting holes 61 are equidistantly distributed along the length direction of the telescopic rod 6, and a bolt 62 and a nut 63 are also provided on the telescopic rod 6, and the bolt 62 passes through the first connecting hole 51 and the second connecting hole 61 in sequence and is threadedly connected to the nut 63; a guide plate 7 is fixedly and horizontally mounted on one end of the telescopic rod 6 away from the fixed tube 5, and both ends of the guide plate 7 are convex arc-shaped, and the distance between the bottom end of the guide plate 7 and the top end of the conveyor belt 14 does not exceed 1 / 2 of the thickness of the cardboard.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
