Technical Field

[0001] This utility model relates to the field of adjustment bracket technology, and in particular to an ink-equalizing device for the inking roller of a printing press. Background Technology

[0002] The ink distribution device on the inking roller of a printing press is a key component used to ensure the uniform distribution of ink. Its main function is to crush and disperse the ink, so that the ink forms a uniform ink layer on the surface of the inking roller, ensuring that the ink color of the printed matter is uniform and consistent, and improving the printing quality.

[0003] In the prior art, the distance between the ink distribution roller and the ink distribution roller in the ink distribution roller of the printing press is usually fixed. Their relative positions are fixed during equipment assembly or debugging. It is impossible to flexibly adjust the distance between the two rollers according to different working conditions in the actual printing process, which results in limited ink distribution effect and difficulty in meeting diverse printing needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing ink-spreading devices for printing press inking rollers, where the distance between the ink-spreading roller and the ink roller is usually fixed and cannot be adjusted according to different working conditions in the actual printing process, resulting in limited ink-spreading effect and difficulty in meeting diverse printing needs. Therefore, this invention proposes an ink-spreading device for printing press inking rollers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ink-equalizing device for an inking roller of a printing press, comprising a machine body, an inking roller body, and an ink supply roller. An adjustment device is provided on one side of the machine body. The adjustment device includes two side plates, one side of which is fixedly connected to the machine body. A U-shaped frame is fixedly connected to one side of the two side plates. A servo motor is fixedly connected to one side of the U-shaped frame. A threaded rod is fixedly connected to the output end of the servo motor. An internal threaded ring is threaded onto the arc surface of the threaded rod. A U-shaped plate is fixedly connected to one end of the internal threaded ring. Circular holes are provided on both sides of the U-shaped plate. A drive motor is fixedly connected to one side of the U-shaped plate. An ink-equalizing roller is fixedly connected to the output end of the drive motor.

[0006] The effect achieved by the above components is as follows: the servo motor starts and outputs to drive the threaded rod to rotate, thereby adjusting the position of the internal threaded ring. The U-shaped plate drives the drive motor to move, causing the ink roller to move away from or closer to the ink roller body. The drive motor starts and outputs to drive the ink roller to rotate.

[0007] Preferably, two circular blocks are fixedly connected to one side of the U-shaped plate.

[0008] The effect achieved by the above components is that the two circular blocks are fixed on the U-shaped plate.

[0009] Preferably, one end of the circular block is fixedly connected to a telescopic rod, and the arc surfaces of the two telescopic rods are fixedly connected to the U-shaped frame.

[0010] The effect achieved by the above components is that the movement of the circular block causes the output end of the telescopic rod to extend or retract.

[0011] Preferably, both ends of the U-shaped frame are fixedly connected to limiting plates, and the side of the two limiting plates that are close to each other is slidably connected to the U-shaped plate.

[0012] The effect achieved by the above components is that the U-shaped plate slides on the two limiting plates, preventing the U-shaped plate from shifting its position during movement.

[0013] Preferably, a scraping device is provided on one side of the U-shaped plate. The scraping device includes two assembly blocks. One end of the two assembly blocks is fixedly connected to the U-shaped plate, and an assembly plate is slidably connected to the outer side of the assembly blocks.

[0014] The effect achieved by the above components is that the assembly plate and the assembly block are compatible, and the two assembly blocks are fixed on the U-shaped plate.

[0015] Preferably, a bolt is threadedly connected to one side of the assembly plate, and the arc surface of the bolt is threadedly connected to the assembly block.

[0016] The effect achieved by the above components is that after the assembly plate and assembly block are assembled, bolts are screwed into the assembly plate and assembly block to fix them together.

[0017] Preferably, a stabilizing plate is fixedly connected to one side of the two assembly plates that are close to each other.

[0018] The effect achieved by the above components is to secure the plate between the two assembly plates.

[0019] Preferably, a scraper plate is fixedly connected to one side of the stabilizing plate.

[0020] The effect achieved by the above components is to fix the scraper plate to the stabilizing plate.

[0021] Preferably, a stabilizing rod is fixedly connected to one side of the two assembly plates that are close to each other.

[0022] The effect achieved by the above-mentioned components is to fix the stabilizing rod between the two assembly plates and prevent the two assembly plates from deforming.

[0023] In summary, the beneficial effects of this utility model are as follows: 1. In this utility model, when the position of the ink-distributing roller needs to be adjusted, the servo motor starts and the output end drives the threaded rod to rotate. The U-shaped plate is moved through the internal threaded ring, so that the ink-distributing roller moves closer to or further away from the inking roller. At the same time, the drive motor drives the ink-distributing roller to rotate, ensuring the continuity of ink distribution. Through the adjustment device, the problem of the ink distribution device of the inking roller of the traditional printing press, where the distance between the ink-distributing roller and the inking roller is usually fixed, cannot be adjusted according to the different working conditions in the actual printing process, resulting in limited ink distribution effect and difficulty in meeting diverse printing needs is solved.

[0024] 2. In this utility model, when it is necessary to scrape off the ink on the surface of the ink-spreading roller using the scraping device, the assembly block is fixed on the U-shaped plate, and the assembly plate and the assembly block are fixed with bolts, so that the scraping plate fits against the ink-spreading roller and scrapes off the ink on its surface, thereby achieving uniform ink layer. The scraping device solves the problem that traditional ink-spreading devices for printing press inking rollers lack a real-time scraping mechanism for the ink on the surface of the ink-spreading roller during the ink-spreading process. The accumulated ink will be directly transferred to the inking roller as the ink-spreading roller rotates, resulting in uneven ink distribution. Attached Figure Description

[0027] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: an ink distribution device for an ink roller of a printing press, including a machine body 1, an ink roller body 4 and an ink supply roller 5. An adjustment device 2 is provided on one side of the machine body 1, and a scraping device 3 is provided on one side of the U-shaped plate 206.

[0028] The specific settings and functions of the adjustment device 2 and the scraping device 3 will be explained in detail below.

[0029] Reference Figure 2 As shown in this embodiment: the adjustment device 2 includes two side plates 201. One side of the two side plates 201 is fixedly connected to the machine body 1. A U-shaped frame 202 is fixedly connected to one side of the two side plates 201. A servo motor 203 is fixedly connected to one side of the U-shaped frame 202. A threaded rod 204 is fixedly connected to the output end of the servo motor 203. An internal threaded ring 205 is threadedly connected to the arc surface of the threaded rod 204. A U-shaped plate 206 is fixedly connected to one end of the internal threaded ring 205. Circular holes 207 are opened on both sides of the U-shaped plate 206. A drive motor 208 is fixedly connected to one side of the U-shaped plate 206. An ink distribution roller 209 is fixedly connected to the output end of the drive motor 208. The system achieves the effect of servo motor 203 starting output driving threaded rod 204 to rotate, thereby adjusting the position of internal threaded ring 205. U-shaped plate 206 drives drive motor 208 to move, causing ink roller 209 to move away from or towards ink roller body 4. Drive motor 208 starts output driving ink roller 209 to rotate. Two circular blocks 212 are fixedly connected to one side of U-shaped plate 206, achieving the effect of fixing the two circular blocks 212 to U-shaped plate 206. Telescopic rods 210 are fixedly connected to one end of each circular block 212, and the arc surfaces of the two telescopic rods 210 are fixedly connected to U-shaped frame 202. This achieves the effect of moving the circular blocks 212 to extend or retract the output end of the telescopic rods 210. Limiting plates 211 are fixedly connected to both ends of U-shaped frame 202, with the sides of the two limiting plates 211 close to each other slidably connected to U-shaped plate 206. This achieves the effect of allowing the U-shaped plate 206 to slide on the two limiting plates 211, preventing the U-shaped plate 206 from shifting position during movement.

[0030] Reference Figure 4 As shown in this embodiment: the scraping device 3 includes two assembly blocks 31, one end of which is fixedly connected to the U-shaped plate 206, and an assembly plate 32 is slidably connected to the outer side of the assembly blocks 31. This achieves the effect of the assembly plate 32 and the assembly blocks 31 being compatible and the two assembly blocks 31 being fixed on the U-shaped plate 206. A bolt 36 is threadedly connected to one side of the assembly plate 32, and the arc surface of the bolt 36 is threadedly connected to the assembly block 31. This achieves the effect of fixing the assembly plate 32 and the assembly blocks 31 by screwing the bolt 36 into the assembly plate 32 and the assembly blocks 31 after assembly. A stabilizing plate 34 is fixedly connected to the side of the two assembly plates 32 that is close to each other. This achieves the effect of fixing the stabilizing plate 34 between the two assembly plates 32. A scraping plate 33 is fixedly connected to one side of the stabilizing plate 34. This achieves the effect of fixing the scraping plate 33 to the stabilizing plate 34. A stabilizing rod 35 is fixedly connected to the side of the two assembly plates 32 that is close to each other. This achieves the effect of fixing the stabilizing rod 35 between the two assembly plates 32, thus preventing the two assembly plates 32 from deforming.

[0031] Working principle: When the position of the ink distribution roller 209 needs to be adjusted via the adjustment device 2, the operator first electrically connects the drive motor 208 and the servo motor 203 to the control system of the printing press. The servo motor 203 is then started. After the servo motor 203 starts running, its output end drives the threaded rod 204 to rotate. This, through the position adjustment of the mating internal threaded ring 205, drives the U-shaped plate 206 to move away from or towards the U-shaped frame 202, thereby causing the ink distribution roller 209 to move closer to or further away from the inking roller body 4. Simultaneously, the drive motor 208 starts and drives the ink distribution roller 209 to rotate, ensuring even ink distribution. The continuity of the process is achieved by sliding the U-shaped plate 206 on the limiting plate 211 during its movement. At the same time, the circular block 212 moves, causing the telescopic rod 210 to extend or retract accordingly according to the moving direction of the U-shaped plate 206. This achieves structural self-adaptation or limiting support during the position adjustment process. Through the adjustment device 2, the problem of the ink distribution device of the inking roller in traditional printing presses is solved. The distance between the ink distribution roller 209 and the inking roller is usually a fixed structure, which cannot be adjusted according to different working conditions in the actual printing process, resulting in limited ink distribution effect and difficulty in meeting diverse printing needs.

[0032] When the ink on the surface of the ink-distributing roller 209 needs to be scraped off using the scraping device 3, the operator first fixes the two assembly blocks 31 on the U-shaped plate 206, and then fastens the assembly plate 32 to the assembly blocks 31 with bolts 36. After assembly, the stabilizing plate 34 drives the scraping plate 33 to come into contact with the surface of the ink-distributing roller 209. During the rotation of the ink-distributing roller 209, the scraping plate 33 can continuously scrape off the excess ink on its surface, achieving uniform control of the ink on the surface of the ink-distributing roller 209. The scraping device 3 solves the problem that traditional ink-distributing devices for printing press inking rollers lack a real-time scraping mechanism for the ink on the surface of the ink-distributing roller 209 during the ink-distributing process. The accumulated ink will be directly transferred to the inking roller as the ink-distributing roller 209 rotates, resulting in uneven ink distribution.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
