1, the mechanical properties of offset
For modern high-speed multi-color sheet-fed offset press to the paper part, it not only to ensure high-speed printing to paper, the stability and accuracy, but also take into account all factors that, in order to adapt to different types and format of the printing material.
Komori of the eight nozzle used to machine Design , Can be 0.04 ~ 0.8mm thick paper for stability and transport, and transport board remains the step belt, and its on with a brush may be feeding the whole movement, and the paper round, this arrangement is not very standard or quality not ideal printing materials have good adaptability.
Order to ensure the accuracy of feed, to prevent failure and waste of paper feed, Komori using mechanical, photoelectric, and inductive forms of combination of oblique to the paper process, two sheets, blank sheets to control. The gripper mechanism is not popular with hem-type moment, but is still on the swing. The current printer speeds of up to 15,000 / hour, smooth and accurate delivery of paper, there is no instability to the paper and print speed do not increase the argument, but also eliminates the need for a feed (forward paper) drum, commonly used four-color printing, only 8 to complete the transfer of paper, of course, the printing will have a further guarantee of quality.
In addition, swinging the shaft to install anti-paper teeth loose end loose end device can compensate for the paper, it is of practical significance to domestic users.
Printing part of the cylinder arrangement is not important, because whether it is "seven" o'clock or "5" o'clock layout, all have their short length. From a practical effect, the arrangement of different machines in the printing quality and operability of the machine is not on the difference Moreover, manufacturers in some product lines in the two layouts are.
Double-diameter impression cylinder and double-track delivery roller printing in ensuring the quality and adaptability of the advantages of expanding practice has been confirmed. Komori Sheet-fed offset press Is this way, but wrap system does not use the air cushion guide popular form of paper, instead of using the on special bread with anti-dirty cloth rubbing with paper roll body of the delivery roller to ensure the delivery process of sheets of paper are not virtually scratch and scratch.
Komori is the only printing company is back in two ways, that is, with a flip of the double-sided printing and double-sided print double-sided mouth Diao unique manufacturers, but also the only commercial production of dual- Double layer offset press manufacturers, this model is books and magazines for color printing market, and since 1998 has been installed in the model in the world more than 40.
From the manufacturing and user situation, the two pairs of the Indian way of double-sided printing with flip transition because of the paper more often, in the long-term use of mechanical wear and tear caused by the accumulated error would be printed on product quality the impact and inconvenience to maintenance, time outside, on the first four-color quick-drying inks have special requirements.
Double-sided printing single Diao mouth way, while Diao paper because it is used to imprint the delivery of the embossed paper transfer method, not only the back of the print quality to ensure consistency and precision register, and the great extent, solve the flip-Indian face rub dirty, Diao mouth, both positive and negative issues register. In addition, this single Diao mouth way now of domestic non-standard format of the paper has a strong adaptability.
Teeth on the transfer roller shaft, Diao tooth structure and material of the register to ensure the accuracy and reduce the instability of ink on the printing presses bearing the adaptability and durability of materials play an important role, Komori using large diameter tooth axis torsion bar to enhance the strength of gripper pad of paper thickness adjustment device can respond quickly, which is carbon steel teeth Diao painted diamond formed, can greatly enhance its durability.
Printing ink part of the input distribution system, is long or short ink ink arrangements shall be justified. Komori ink by a long way, from four different diameter and 4 by channeling Roller roller for the layout to provide uniform ink film, which is a copper roller roller channeling its excellent ink transfer, better heat dissipation , easy to clean.
