Description

Technical Field

[0001] This application relates to the field of printing roller technology, and in particular to a printing roller with a self-cleaning function. Background Technology

[0002] Printing rollers are core components of offset printing presses, mainly used to transfer ink and dampening solution. The microporous structure of their surface directly affects printing quality. After prolonged use, printing rollers will accumulate a lot of impurities on their surface, affecting the printing effect of the product. Therefore, it is necessary to clean the surface of the printing rollers through a cleaning mechanism.

[0003] While existing cleaning mechanisms can scrape and clean the surface of printing rollers, the contact between the scraper and the printing roller is relatively hard, resulting in poor all-round contact between the cleaning fluid and the surface of the printing roller. This makes it easy for impurities to harden when the scraper directly contacts the printing roller for cleaning, leading to incomplete scraping and affecting the quality of cleaning the printing roller. Utility Model Content

The surface of the bearing 4 is provided with a cleaning mechanism for cleaning the surface of the printing roller, the cleaning mechanism including a cleaning channel 9 and a flow hole 11. A rotary joint 8 is rotatably connected to the inner wall of the bearing 4. The printing roller body 2 has a cleaning channel 9 for axial flow of cleaning fluid, and a connecting pipe 10 fixedly connected to the outer wall of the cleaning channel 9 and the inner wall of the printing roller body 2. Micropores 3 are formed on the surface of the printing roller body 2 for conveying cleaning fluid to the surface of the printing roller. The cleaning channel 9 is connected to a supply pipe 7 via the rotary joint 8. The connecting pipe 10 is hollow inside. A flow hole 11 is provided at the connection between the outer wall of the cleaning channel 9 and the connecting pipe 10. The micro-hole 3 is connected to the cleaning channel 9 through the connecting pipe 10 and the flow hole 11. When the printing roller needs to be cleaned, the connecting pump on the cleaning liquid storage tank 5 is turned on, so that the cleaning liquid is delivered to the rotary joint 8 through the liquid supply pipe 7. Through the connection of the bearing 4, the cleaning liquid is delivered to the cleaning channel 9. With the opening of the flow hole 11, the cleaning liquid is delivered to the connecting pipe 10 and flows out through the micro-hole 3, so that the cleaning liquid is distributed on the surface of the printing roller. With the cleaning scraper 13 contacting the printing roller and the rotation of the printing roller, the surface of the printing roller is cleaned in all directions.

[0033] Reference Figure 1 and Figure 3 The outer wall of the connecting frame 1 is provided with a cleaning fluid storage cylinder 5. The bottom of the cleaning fluid storage cylinder 5 is fixedly connected to a delivery pipe 6 via a connecting pump. The top of the cleaning fluid storage cylinder 5 is fixedly connected to a supply pipe 7 which is fixedly connected to the end of the rotary joint 8 via a connecting pump, so as to achieve the effect of convenient delivery of cleaning fluid.

[0034] Reference Figure 2 and Figure 4An electric push rod 12 is provided at the bottom of the connecting frame 1. A cleaning scraper 13 is fixedly connected to one end of the electric push rod 12. A lifting rod 14 that is slidably connected to the outer wall of the connecting frame 1 is fixedly connected to the bottom of the cleaning scraper 13.
