Goss N75 Printable Wide and Narrow Newspaper Transformation Method and Printable Wide and Narrow Newspaper Double-width Rotary Machine

Abstract

The invention provides a Gaussian N75 printable wide and narrow newspaper transformation method. Through the steps of triangular plate cutting, base platform hole expansion, moving quantity modification and main paper leading roller group transformation, the narrow-width newspaper printing requirements with great dimension differences can be further met on the basis of maintaining the original wide-width newspaper printing, in addition, the cost of the transformation method is low, and in addition, the wasted work hours are few. In addition, the invention simultaneously provides a printable wide and narrow newspaper double-width rotary press, which is different from ordinary products, through adopting a novel triangular plate structure, a main paper leading roller structure, a transmission structure and a design of sufficient triangular plate horizontal moving quantity, the fast regulation can be realized, so the narrow-width newspaper printing requirements with great dimension differences can be met.

Description

technical field [0001] The invention relates to the field of newspaper printing equipment, in particular to a reforming method for Goss N75 printable wide and narrow newspapers and a double-width rotary machine capable of printing wide and narrow newspapers. Background technique [0002] With the introduction of the national energy-saving and consumption-reducing policy, newspaper operators are also thinking about how to save energy and reduce consumption. In addition to reducing the layout of the newspaper, reducing the size of the newspaper format is also an important choice. In addition to being convenient for readers to read, it can save paper and achieve greater economic benefits. Overprinting, this practice is also called "newspaper slimming" ". [0003] For this reason, a new type of newspaper format was born, and its printing area (print center) is 38.5 cm x 24 cm, 49.5 cm x 30 cm, 48 cm x 31 cm or 52 cm x 32 cm. narrow newspaper". Narrow newspapers originated in ...

AI Technical Summary

Problems solved by technology

[0009] 1. Unable to meet the printing centering requirements - the main reason is that the adjustment stroke between the two sets of triangle mechanism of the folding machine is insufficient, which is specifically reflected in: the horizontal distance between the two triangles is too small to meet the printing requirements of narrow newspapers; the location of the triangle is fixed The design movement of the frame is only ±10mm, which cannot meet the printing movement requirements of narrow newspapers above 50mm

Furthermore, the lengths of the two threading rollers corresponding to each triangular plate in the main threading roller group are fixed, and the adjustable range is very small. Unable to align with the center of the set square for printing jobs

Secondly, the width of the platen area of ​​the paper threading roller in the main threading roller group is limited, and it will be difficult to press the paper well after the triangular plate is excessively shifted

[0010] 2. Loss of threading power - mainly due to the fact that the first threading roller group and the second threading roller group fixed on the same fixed frame also need to move synchronously with the fixed frame when the triangle plate mechanism moves horizontally, so as to ensure that the triangle plate and the second threading roller group Centering requirements for a threading roller set

After the driving fixed frame moves more than 10mm, the transmission gear in the gear box that drives the first threading roller group will gradually separate from the main transmission gear, and then lose power, so that the above first threading roller group loses the paper threading power and cannot normal work

[0011] In addition, the incompatibility of the threading rollers to the paper is also a problem, which is mainly reflected in the first threading roller set, the second threading roller set and the third threading roller set corresponding to each triangle plate in the original folding machine The position setting of the traction wheel is only suitable for 1562mm paper printing, and there will be a problem of not being able to press the paper when printing narrow newspapers
