Problems solved by technology

Even very small variations in this spacing between the doctor blade and the roller, on the order of a few microns, can result in uneven application of ink to the roller, reducing print quality
Additionally, in the area between the screws, ink may seep between the doctor blade and clamp rail and between the doctor blade and the doctor blade chamber, further enhancing the "flashing" effect and requiring frequent cleaning
Third, tools are needed to loosen and tighten screws
Failure to use this tool for replacement during work, for example due to a colleague misplacing the tool, can be a major source of irritation for the worker

Embodiment Construction

[0121] figure 1 It is a perspective view of a part of the doctor blade chamber 1 according to the prior art. For illustration, the doctor blade chamber 1 is shown without an end cap, which normally seals the end 2 so that ink does not flow out of the doctor blade chamber 1. The doctor blade 4 sandwiched between the clamping rail 5 and the doctor blade chamber 1 is mounted on the doctor blade chamber 1. Screw the clamp rail 5 to the doctor blade chamber 1 with bolts 6. The doctor blade chamber 1 and the doctor blade 4 together constitute the wall of the ink 7. When the doctor blade cavity 1 is aligned with the transfer roller, the open channel 8 between the doctor blades 4 is closed.

[0122] figure 2 A cross-sectional view of the doctor blade chamber 1 and the transfer roller 9 according to the prior art is shown. When the two doctor blades 4 contact the roller surface 10, the ink chamber 7 is substantially closed. When the ink transfer roller 9 rotates along its axis, the p...

Abstract

A combined scraper cavity for the roller printing unit scraper cavity system (1), the scraper cavity (1) comprises an open channel (8) on the front side, wherein the scraper cavity is formed by two combined profiles, i.e., an open profile having an front and rear side (30) and a closed profile having a front and rear side (33), wherein the front side of the open profile (31) and the back side of the closed profile (35) are engaged, thereby achieving low weight, high strength, strong corrosion resistance, easy to clean the surface, ink waste reduction, Beautiful appearance and improved working environment. Further than an object of the present invention is to provide an ink scraper cavity system having the above advantages, wherein the ink scraper can be replaced faster and more easily without the use of tools.

Description

Technical field [0001] The invention relates to a method for preparing a combined doctor blade cavity comprising two combined profiles. [0002] The invention also relates to a combined doctor blade chamber for a doctor blade chamber system of a cylinder printing unit, the doctor blade chamber including a front side with an open channel. [0003] In addition, the present invention relates to a doctor blade chamber system, which is used in a cylinder printing unit including a doctor blade chamber, a clamp rail and a doctor blade. [0004] In addition, the present invention relates to the application of the doctor blade chamber system. Background technique [0005] In cylinder printing units for offset printing, flexographic printing and other kinds of printing, it is advantageous to use a system including a so-called doctor blade cavity. The doctor blade cavity is an ink container, which is closely attached to the transfer roller by a so-called doctor blade, and transfers the ink from...
