Description

Four-color oil film centralized supply device for printing machine

Technical Field

The utility model relates to a lithography apparatus's technical field specifically is a four-color oil film concentrates feeding mechanism for printing machine.

Background

Printing machines are machines for printing text and images, modern printing machines generally consisting of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate. The invention and the development of the printing machine play an important role in the propagation of human civilization and culture. Currently, factors affecting the quality and efficiency of printed products are manifold, including overprinting accuracy of equipment, printing materials and printing inks, etc. The ink influencing factors are difficult to control, and comprise the concentration of the ink, the viscosity of the ink, the content of a solvent, the temperature of the ink, the supply amount of the ink and the like.

At present, ink supply of a printing machine is usually to directly add ink into an ink tank, the ink is often partially oxidized due to overlong standing time or poor sealing, so that impurities after crystallization and precipitation exist in the ink, and when the impurities are overlarge, the quality problems of black spots, dirty spots and the like of a printed product can be caused, and the prior patent application number: 202121987410.1 patent, send the black pipe including open printing ink bucket and the owner that has the branch pipe, the owner send the black pipe to set firmly in the top of printing ink bucket, install the bung in the printing ink bucket, be provided with seal structure between the inner wall of bung and printing ink bucket, the other direction subassembly that is provided with of printing ink bucket, make the bung slide along the axial lead of printing ink bucket through the direction subassembly, be provided with the printing ink pump on the bung, the end of advancing of printing ink pump runs through the bung, the play black end of printing ink pump is connected with the hose, the other end and the branch union coupling of hose, still be provided with the subassembly that admits air on the bung, play the sealed inner chamber of closing printing ink bucket through the subassembly that admits air. The utility model has the advantages that: the printing ink in the printing ink barrel is conveyed to the printing machine through the printing ink pump, when the printing ink in the barrel is reduced, the barrel cover is connected with the printing ink barrel in a sealing mode, the printing ink pump moves to the barrel bottom along with the barrel cover, the printing ink is kept in a sealing storage mode, and the risk of oxidation of the printing ink is reduced.

To above-mentioned relevant technical scheme, the inventor thinks, when it changed has ink barrel, can't fix a position and fix ink barrel, probably the bung can't correspond with ink barrel after the change, probably leads to ink barrel to overturn, needs user manual positioning, influences printing efficiency.
