[0002] The anilox roller is a roller used in flexographic and gravure printing processes. It has a precise anilox surface and is used to control the amount of ink or paint to ensure a uniform coating effect. When the anilox roller rotates too fast, the ink will be thrown off the surface of the anilox roller due to centrifugal force. The baffle is adapted to the shape of the roller of the printing press to maximize coverage of the area where ink may be thrown.

The baffle plate is fixedly arranged on the support assembly, and the rotating assembly is connected to the support assembly and is used to rotate the support assembly. This application reduces the situation where the ink roller affects the printing efficiency due to ink throwing problems. However, when the rotation speed of the anilox roller is too fast, the edges at both ends are prone to gather ink, which makes it easier for the two ends of the anilox roller to throw ink.

In order to block the ink dots thrown out by the anilox roller 4, a mounting slot 6 is designed on the top of the fixed pillar 3, and a baffle 7 is installed in the mounting slot 6. A positive rubber slide 8 is installed at the bottom end so that the baffle 7 can fit tightly on the surface of the anilox roller 4, thereby effectively blocking the splashing of ink dots.

[0046] Working principle: fixed pillars 3 are installed on the left and right sides of the bottom plate 1 to provide stable support so that the anilox roller 4 can rotate. The anilox roller 4 is responsible for evenly transferring ink to the printed paper. In order to block the ink dots thrown out by the anilox roller 4, a mounting slot 6 is designed on the top of the fixed pillar 3, and a baffle 7 is installed in the mounting slot 6. A positive rubber slide 8 is installed at the bottom of the baffle 7 so that the baffle 7 can fit tightly on the surface of the anilox roller 4, thereby effectively blocking the splashing of ink dots. Since the corners of the anilox roller 4 easily gather ink, it is easier for both ends of the anilox roller 4 to throw ink. The ink dots are thrown onto the printed paper and will contaminate the printed paper. Therefore, side rubber baffles 9 are installed on the left and right sides of the baffle 7. The side rubber baffles 9 can prevent ink dots from splashing from the side to ensure the cleanliness of the printed paper. At the same time, it is convenient to adjust the height and angle of the baffle 7. A threaded rod 10 runs through the top of the baffle 7. By rotating the rotating valve 11 on the threaded rod 10, the distance between the baffle 7 and the anilox roller 4 can be easily adjusted to adapt to papers of different specifications and thicknesses.

[0047] In addition, the paint in the storage box 201 is driven by the water pump 202 and transported to the rolling trough 5 through the supply pipe 203. During the processing, the height and distribution status of the paint in the rolling trough 5 are monitored in real time by the upper and lower pressure sensors. When the upper pressure sensor 204 senses that too much paint has accumulated, the water pump 202 will stop working immediately to avoid paint overflow. The lower pressure sensor 205 monitors the status of the bottom of the paint in real time. If it is detected that there is too little paint, it will cause uneven processing or idling. At the same time, the water pump 202 is automatically started to replenish the paint. If the paint in the rolling trough 5 needs to be reused, it can be returned to the storage box 201 through the return pipe 206, and the electromagnetic valve 207 can be controlled to open or close to ensure that the paint can flow back smoothly.
