Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection, in particular to a ceramic anilox roller constant pressure detection device. Background Art

[0002] After the ceramic anilox roller is produced, it needs to be tested for constant pressure to ensure that it can transfer ink evenly and stably during the printing process, thereby ensuring the printing quality.

[0003] In the prior art, compressed air can be used to perform constant pressure testing on the ceramic anilox roller, and the pressure on the anilox roller during the actual printing process is simulated by introducing compressed air. This test can ensure the performance stability of the anilox roller in actual use and the uniformity of ink transfer. At present, for production-oriented enterprises, air compressor stations are usually used to provide compressed air with a certain air pressure as a power source for pneumatic equipment, and corresponding shared compressed air pipelines are formed to be distributed in various areas of the enterprise for use at any time. However, since the compressed air provided by the shared compressed air pipeline is prone to unstable pressure, when the compressed air in the shared compressed air pipeline is directly used to detect whether there is a leak in the product, it will not be detected due to pressure fluctuations, thereby affecting the test results. In addition, there may be a certain amount of water vapor and oil in the compressed air, and the direct use of compressed air will also have a certain impact on the test use. Utility Model Content
