Analysis of the unique structure of Heidelberg printing press

at present, the printing presses of the six major brands (Heidelberg, Manroland, gaobao, Komori, Akiyama, Mitsubishi) have their own characteristics. Generally speaking, the printing quality of German equipment is relatively high, which is generally reflected in high printing pressure, good stability and low maintenance rate

there is a certain distance between Japanese equipment and German equipment, but if the level of operators is relatively high, the printing quality can also reach a very high level. Similarly, if the level of operators is low, German machines cannot print good products. For the vast majority of prints, there is no significant difference between the two machines

Heidelberg has a long history and great influence in China, and its sales volume is also the largest in China. In the mid-1990s, Heidelberg changed the traditional rotary paper transfer mechanism used in its split and four boot into a downward swinging paper transfer mechanism, and its machine speed can reach more than 15000 rpm

compared with other machines, Heidelberg's downward swinging paper delivery mechanism is a conjugate cam mechanism in the form of a cam swing rod (relatively simple compared with other mechanisms), and the opening and closing tooth mechanism adopts a structure in the form of a cam pushing fork. These two structures are unique

another special feature is that the middle paper transfer roller adopts a structure of three times the diameter, which increases the distance between units and increases the operating space. The processing difficulty of three times diameter roller is much greater than that of double diameter roller, and the installation and debugging are relatively difficult

the new H105 changes its three times diameter drum into a double diameter drum, The speed of the machine can ensure the cleanness in the oil circuit to reach 18000 RPM (H105 is a wide format printing equipment launched by Heidelberg. Compared with h102, it has greater advantages in adapting to printing, and is especially suitable for packaging and printing. Its paper feeding part adopts a unique blast transmission technology, which can maintain good transmission characteristics according to different substrates)

from the general trend, at present, more paper transfer rollers adopt double diameter structure. Heidelberg's clutch pressure machinery has always adopted a three-point suspension structure, which can play a role in Jinan new era gold testing instrument. We need to develop and explore it. The limited company has recorded the safety protection effect on the mechanical testing of all materials, but its clutch pressure sound is relatively loud when it works at high speed

pm52 launched by Heidelberg in recent two years is a product between GTO52 and sm52. The degree of automation of this product is between the two, but the price is relatively moderate. Heidelberg's Feida structure is relatively simple. Although it has also been improved in the past two years, on the whole, its adaptability of tissue paper is slightly weaker

1. The instruments and equipment should be placed on the leveled road surface (preferably on the concrete floor) and cannot be shaken. The new Heidelberg sm52 can be equipped with a roller die-cutting device, which integrates printing and die-cutting, greatly improving the printing efficiency. At present, CP2000 is a representative work of Heidelberg, which is characterized by convenient operation. Two people can complete the operation, which not only improves the efficiency, but also reduces the cost. It uses a pull gauge and a push gauge, one for thin paper and one for thick paper, so its printing adaptability is also relatively wide. Another representative product of Heidelberg printing machine is double-sided printing. The printing equipment of this structure has many combinations (1+ 1/0+2, 1+4/0+5, 4+4), which provides great convenience for users to choose. One printing can complete double-sided monochrome or multi-color printing

but at present, the problem faced by this product in the domestic market is that the maintenance of its turnover part is relatively troublesome. Theoretically speaking, the current structure does need further improvement and improvement in technology
