Description

Technical Field

[0001] The utility model relates to the technical field of printing plate turning mechanisms, in particular to a turning device for printing plate. Background Art

[0002] Printing block refers to the process and technology of engraving words or pictures on wooden or metal plates to make them into printing bases. When printing, a cylindrical flat brush is dipped in ink and evenly brushed on the plate surface. Then paper is carefully covered on the plate surface and the paper is gently brushed with the brush. The positive image of the text or picture will be printed on the paper.

[0003] When a flipping device is used to flip the printing plate, the printing plate is usually directly connected to the rotating shaft of the flipping device. When the plate is rotated by the rotating shaft, the centrifugal force generated is directed toward the rotating shaft. This causes the ink at the center point of the printing plate to diffuse away from the rotating shaft, while the part close to the rotating shaft is stained with less ink. As a result, when this fixing method is flipped, the printing near the rotating shaft is not clear, resulting in poor printing effect. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when a turning device is used to turn over a printing plate, the printing plate is usually directly connected to the rotating shaft of the turning device. When the plate is rotated by the rotating shaft, the direction of the centrifugal force generated is toward the rotating shaft, so that the ink at the center point of the printing plate spreads in the direction away from the rotating shaft, while the part close to the rotating shaft is stained with less ink, resulting in unclear printing on the part close to the rotating shaft when this fixing method is turned over, resulting in poor printing effect. Therefore, a turning device for printing plates is proposed.

[0029] Example 1, as Figure 1-4As shown, a flipping device for printing plate includes a frame 1 and two shafts 5. A first motor 4 is provided on one side of the top of the frame 1. The output end of the first motor 4 is fixedly connected to one end of a shaft 5. One end of the two shafts 5 is respectively rotatably connected to one side of the top of the frame 1. An auxiliary device 2 is provided on the outer surface of one shaft 5. The auxiliary device 2 includes two slot rods 21. One end of the two slot rods 21 is connected to each other. One side of the two slot rods 21 is respectively fixedly connected to one end of one shaft 5. A second motor 24 is provided on one end of the slot rod 21. A T-shaped slot 22 is provided on one side of the slot rod 21. A screw 2 is rotatably connected to the inner wall of the T-shaped slot 22. 3. The output end of the second motor 24 is fixedly connected to one end of the screw rod 23. The outer surface of the screw rod 23 is threadedly connected to a sliding rod 25. One side of the sliding rod 25 slides on the inner wall of the T-shaped slot 22. A bolt 26 is rotatably connected to one side of the inner wall of the sliding rod 25. A clamping plate 27 is threadedly connected to the outer surface of the bolt 26. One side of the sliding rod 25 is fixedly connected to a round rod 28. One end of the inner wall of the clamping plate 27 slides on the outer surface of the round rod 28. One end of the sliding rod 25 on one side of the two slot rods 21 is connected to each other. A plate 6 is set on one side of the two slot rods 21. By setting the clamping plate 27, when using the flip device, ink and engraved paper are placed on the plate 6. Inside, close the plate 6 and place both ends of the plate 6 on the outer surface of the two sliding plates 35 below the clamping plate 27. Then, turn the bolts 26 at the two sliding plates 35 to control the clamping plate 27 to move downward on the outer surface of the bolts 26 and the outer surface of the round rod 28 to press the clamping plate 27 against the outer surface of the plate 6, and fix the position of the plate 6 on the outer surface of the sliding rod 25. Then, operate the first motor 4 to drive the shaft rod 5 and the slot rod 21 to rotate so that the plate 6 continues to flip. At the same time, operate the second motor 24 at one end of the slot rod 21 to drive the screw rod 23 to rotate forward, so that a sliding rod 25 is in the T-slot 22 on one side of the slot rod 21 and the screw 23. The outer surface of the slot rod 21 moves in the direction away from the second motor 24. When the sliding rod 25 moves to one end of the slot rod 21, the second motor 24 is stopped, and the second motor 24 on the outer surface of the other slot rod 21 is operated to drive the screw 23 to rotate in the opposite direction so that the sliding rod 25 on one side of the slot rod 21 moves toward the direction of the second motor 24 along the inner wall of the T-shaped slot 22 and the outer surface of the screw 23.

By setting the rectangular strips 29 made of rubber material, the friction force between the bottom end of the splint 27 and the surface of the stereotyped plate 6 when pressed against the outer surface of the stereotyped plate 6 can be increased, so that the position of the stereotyped plate 6 fixed by the splint 27 is more stably fixed. A positioning rod 210 is fixedly connected to one side of the sliding rod 25. The positioning rod 210 is located below the splint 27. When the stereotyped plate 6 is placed on the outer surface of the two sliding rods 25, the two ends of the stereotyped plate 6 can be respectively pressed against the side of the positioning rod 210 inside the two sliding rods 25, so as to preliminarily limit the position of the stereotyped plate 6 on the outer surface of the sliding rod 25, so as to facilitate the control of the movement of the splint 27 to further fix the position of the stereotyped plate 6.

[0031] Reference Figure 2-4 As shown, in this embodiment: the top end of the bolt 26 is fixedly connected with an operating block 211, and the outer surface of the operating block 211 is provided with a number of protrusions.

One side of the sliding rod 25 is fixedly connected with two positioning blocks 212, and one side of the positioning block 212 slides on the outer surface of the slot rod 21. When the second motor 24 drives the screw 23 to rotate and control the sliding rod 25 to move on one side of the slot rod 21, the two positioning blocks 212 on one side of the sliding rod 25 will slide on the outer surface of the slot rod 21. The positioning blocks 212 can further limit the angle between the sliding rod 25 and the slot rod 21, thereby improving the stability of the sliding rod 25 when moving.

After the stereotype 6 is flipped using the flipping device, the fan blades 32 can be driven to rotate by operating the third motor 31, and at the same time, the plurality of electric heating plates 33 at the bottom end of the frame 1 are operated to generate heat, so that the fan blades 32 rotate to blow high-temperature air to the stereotype 6 to dry the paper inside the stereotype 6. There is no need to transfer the stereotype 6 to the drying equipment for drying again, thereby improving the practicality of the flipping device when in use.
