Description

Technical Field

[0002] A printing press is a piece of mechanical equipment widely used in publishing, packaging, advertising and other industries. Its main function is to transfer graphic information to the substrate through a specific printing method. During the printing process, the inking device is one of the core components of the printing press, and its performance is directly related to the quality of the printed product and production efficiency.

[0003] The traditional inking device of a printing press generally consists of an ink supply part, an ink distribution part and an inking part. The ink supply part usually consists of an ink fountain, an ink fountain roller and an ink transfer roller. Its main function is to store ink and transfer the ink to the ink distribution part. The ink distribution part is responsible for evenly applying the ink on the printing plate. It usually consists of ink rollers such as an ink string roller and an ink distribution roller. The inking part is responsible for applying the ink layer after the ink distribution treatment to the printing plate to complete the printing process.

[0004] However, the existing ink supply device of the printing press has some obvious defects during use. The ink storage and supply and transportation settings of the existing ink supply part and the ink uniforming part are relatively simple. The ink is prone to precipitation or condensation during the ink supply process. The existing ink supply device is usually provided with a stirring mechanism, but the existing stirring mechanism only plays the role of uniformly stirring the ink and reducing precipitation or condensation. It is not easy to uniformly transport the ink and it is difficult to control the smoothness of the ink transportation, which leads to the problem of too much or too little ink during the printing process, thereby affecting the quality of the printed product. In addition, the ink is prone to cooling and precipitation during transportation, which easily causes uneven ink distribution, resulting in defects such as color difference and mottled on the printed product, thereby affecting the printing effect.
