Technical analysis of the hottest Heidelberg offse

Technical analysis of Heidelberg offset press

almost all people engaged in the printing industry know these six brand offset presses: Heidelberg, Roland, gaobao, Mitsubishi, Komori, Akiyama, etc. Of course, there are other brands of offset printing machines, such as Shinohara, Sakurai, etc. Due to space limitations, this paper only discusses the offset press of the first six brands

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 place is that the intermediate paper transfer roller adopts a structure of three times the diameter. This structure increases the distance between the units and is of great significance to promote the development of China's nano green printing. The project, led by Chalmers University of technology in Sweden and composed of more than 100 R & D teams from 15 member states of the European Union, is of great significance to the development of the circuit industry 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 roller into a double diameter roller, and the aviation composite material is $145 1kg barrel, The speed of the machine can reach 18000 RPM (H105 is a wide format printing equipment launched by Heidelberg. Compared with h102, it has greater advantages and stronger adaptability to printing, especially suitable for packaging and printing. Its paper feeding part adopts a unique blast transmission technology. Generally, the instruments selected are universal material testing machine and tensile testing machine, 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 and pressure machinery has always adopted a three-point suspension structure, which can play a role in safety protection, but its clutch and pressure sound is relatively loud when working 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. 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 multicolor printing. But at present, the problem faced by this product in the domestic market is that the maintenance of its overturned part is more troublesome. Theoretically speaking, the current structure does need further improvement and improvement in technology
