It is in line with the national standard GB3264-89 "Technical Conditions for Sheet-fed Lithographic Offset Printing Machines", such as: PZ1740 four-opening single-color offset printing machine is a kind of excellent performance, easy operation, convenient adjustment, stable and reliable operation , a printing press that realizes complete automation of the printing process. It complies with GB3264-89 "Technical Conditions for Sheet-fed Offset Offset Printing Machines". It has the advantages of beautiful appearance, compact structure, reasonable design, reliable use, strong dots, and accurate color registration. It is mainly used for single-color or multi-color overprint printing on offset paper, coated paper, and newsprint. It is suitable for printing plants, institutions, and hospitals. Schools, publishing houses and other units print exquisite albums, illustrations, covers, fine maps, trademarks, packaging and decoration and other high-end color prints, as well as various charts, texts, newspapers, books, books and periodicals, etc. The machine has the following structural characteristics:
The main drive adopts variable frequency speed regulation, which ensures convenient speed regulation and smooth machine operation.
The control circuit adopts PLC programmable controller and photoelectric level control device.
The printing part adopts a sliding bearing structure to ensure good printing pressure, strong dots, and long-lasting machine accuracy.
The base and oil pool adopt an integrated structure, which is beautiful in appearance and effectively solves the problem of oil leakage in the machine.
The eccentric upward swing paper delivery mechanism adopts a yoke cam and a constant force device to ensure smooth, accurate and reliable paper delivery.
Both the printing plate cylinder and the rubber cylinder are equipped with pressure-regulating mechanisms with precise pressure-regulating scales, making it easy to adjust the ideal printing pressure.
The cam on the machine is designed with computer optimization and is made by CNC milling and grinding. The cam profile is reasonable, the processing accuracy is high, the mechanism operates smoothly and the noise is low.
The printing cylinder is equipped with a quick plate clamping device, so the printing plate can be assembled and disassembled quickly and conveniently.
The machine is equipped with a fixed-point, timing and quantitative automatic centralized lubrication system.
The text display is equipped with a fault diagnosis display, which is helpful to find the source of the fault and eliminate it in time.
A rotary pedal is installed on the transmission side, and the cardboard of the paper feeder can be opened, which brings great convenience to adjust the machine.
The machine is equipped with very good safety protection measures. A safety bar is installed between the plate cylinder and the rubber cylinder. Safety bell buttons are installed on many button boards of the machine and are closed. type cover.
