Problems solved by technology
Although the current method can meet various printing requirements and achieve printing purposes, if it is to print printed matter with different specifications and different rubber roller hardness requirements, each color group needs about 30 minutes of downtime to replace the rubber roller, which not only affects production tasks, but also a waste of labor; in addition, it is easy to damage the rubber roller during installation

The invention relates to a multi-rubber-roll interchanging device for a photogravure press. The invention aims at providing a multi-rubber-roll interchanging device which is capable of quickly interchanging rubber rollers according to the printing requirement and has the characteristics of simple structure, convenience and safety in application and lower cost. The technical scheme is that the multi-rubber-roll interchanging device for the photogravure press is characterized by comprising two interchanging mechanisms which are symmetrically distributed on wallboards on the left side and the right side of the photogravure press, wherein each interchanging mechanism comprises a lifting cylinder vertically fixed on each wallboard, a guide rail slide block mechanism arranged on the wallboard below the lifting cylinder, a multi-rubber-roll mounting mechanism arranged on the guide rail slide block mechanism, a driving mechanism distributed on the wallboard at the front side of the lifting cylinder and capable of driving the multi-rubber-roll mounting mechanism to circumferentially run, and a lifting synchronizing gear mechanism vertically distributed on the wallboard at the rear side of the lifting cylinder.
Description
technical field [0001] The invention relates to a matching device for the embossing part of a large gravure printing machine, in particular to a multi-rubber roller transposition device for a gravure printing machine. Background technique [0002] Existing gravure printing machines are composed of several printing units, and each printing unit is composed of a gravure printing roller, a back pressure roller and a rubber roller to form an embossing part, wherein the gravure printing roller is an active rotating part, and the back pressure roller, rubber roller Rollers are passive rotating parts. The two ends of the embossing part are respectively installed on the lifting slide rails of the walls on both sides through the slide block, and the slide block is connected with the piston rod of the cylinder and controlled by the cylinder for lifting and embossing. Rubber rollers play a key role in printing, each printing machine must be equipped with more than two kinds of rubber ...
