Description

Technical Field

[0001] The present invention relates to the technical field of tobacco machinery or tobacco manufacturing equipment, and in particular to an assembly method of a secondary ink distribution device for a cigarette making machine printing system of a PROTOS70 or ZJ17 unit, and in particular to an assembly method of a secondary ink distribution device for a YJ17 cigarette making machine. Background Art

[0002] The ZJ17 cigarette making and assembling machine consists of the YJ17 cigarette making machine and the YJ27 assembling machine. The function of the YJ17 cigarette making machine printing system is to print the trademark pattern on the cigarette paper delivered by the paper supply system, and provide the cigarette forming system with cigarette paper with the trademark pattern. In the process of trademark pattern printing: the ink is delivered to the ink roller through the nozzle in a fixed and quantitative manner, and after passing through an ink distribution roller, the ink is transferred to the ink transfer roller; the ink of the ink transfer roller is then transferred to the steel stamping convex mold on the circumference of the steel stamping roller to produce an ink pattern; the steel stamping roller, in cooperation with the printing roller, prints the ink pattern on the cigarette disc paper between the two, forming the trademark pattern of the cigarette paper.

[0003] At present, during the printing process of trademark patterns on cigarette paper, the ink on the ink roller is only passed through the ink distribution roller once before being transferred to the ink transfer roller; the ink on the ink transfer roller is not fully evenly pressed, making the ink uneven and even containing bubbles and particles. When such ink is transferred to the stamping die, it is easy to cause the trademark pattern to be blurred and the color depth to be different (color difference), affecting the printing quality of the trademark pattern; at the same time, the ink roller has axial reciprocating motion during work. If the ink is uneven, it is easy to cause ink squeezing and splashing between the ink distribution roller, ink roller, and ink transfer roller, which is not conducive to the cleaning, maintenance and on-site management of the printing system.

[0004] Therefore, the concept of secondary ink distribution is established, and secondary ink distribution rollers and ink distribution devices are added to distribute the ink on the ink transfer roller for the second time, so as to achieve the stability and reliability of uniform ink distribution and solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an assembly method for a secondary ink uniforming device for a YJ17 cigarette making machine, establish a secondary ink uniforming concept, add a secondary ink uniforming roller and an ink uniforming device; achieve uniform distribution of ink by performing a second ink uniforming on the ink transfer roller; improve the stability and reliability of printing of cigarette paper trademark patterns; and at the same time, facilitate cleaning, maintenance and on-site management of the printing system.
