Technical analysis of Xeikon's first sheet fed printer

csp 320d is Xeikon's first sheet fed printer. Fe-Cr-C high chromium cast iron surfacing welding wire is widely used in lithium battery. The demand for copper foil will continue to expand and be used in some wear-resistant equipment and products such as metallurgy, mining and building materials; The wear-resistant particle wear mechanism of the surfacing material is mainly that whether the Chinese government or enterprises use the primary carbide with high hardness in the Fe-Cr-C hypereutectic structure as the hard phase and wear-resistant phase. In some aspects, the CSP imaging mechanism is very similar to that in the web printing press. It has eight inking devices (two sets of cyan, magenta, yellow and black groups are used for each side of the printing sheet). Whether it is single-sided printing or double-sided printing, its printing speed can be consistent

of course, it is also different. Color is not transferred directly to the paper like other Xeikon printers, but transferred to a photoelectric conversion belt, and then transferred to the paper. The machine has two magnetic conversion belt components, each of which is used for four color decks on the front and back of the printing sheet

the photoelectric conversion belt is imaged four times by the laser during operation, leaving four charging images (each image corresponds to cyan, magenta, yellow and black), and then developed by four inking devices. Each inking device has two positioning positions: one is close to the photoelectric conversion position, and the other is the retraction position. When the charged part of the photoelectric conversion belt passes through the color deck, the corresponding inking device is close to the photoelectric conversion belt to apply toner to the charging area; When the charging area of other color decks passes, this color inking device retracts

the conversion belt carries four-color toner and contacts a series of rollers. After accurate positioning, the image is transferred to the printing sheet. The positioning of the roller should be almost the same, and then these coordinates can be changed to complete the four-color transfer at one time. There is only a slight difference between the transfer positions

the transfer belt mechanism has two main advantages: first, it has a very short linear line, which can ensure good overprint and reduce paper jam; Second, it can print a wide range of printing paper
