Rapid cleaning and maintaining mechanism for blanket cylinder of offset press

Abstract

The invention relates to a rapid cleaning and maintaining mechanism for a blanket cylinder of an offset press, the rapid cleaning and maintaining mechanism is used for being installed on an offset press to clean and maintain the blanket cylinder. The rapid cleaning and maintaining mechanism comprises a rotating bracket with a herringbone cross section, the bracket has a rotating shaft, a washing device mounting plate is arranged around the rotating shaft on the bracket, a cleaning agent washing device mounting plate and a reducing agent smearing device mounting plate, the washing device mounting plate, the cleaning agent washing device mounting plate and the reducing agent smearing device mounting plate are arranged on the support around the rotating shaft, the washing device comprises a first spray head set and a first suction head roller, and the cleaning agent washing device comprises a second spray head set and a second suction head roller, each of the first spray head set and each of the second spray head set all comprises a plurality of nozzles which are uniformly arranged along the axial direction of the bracket; the rapid cleaning and maintaining mechanism for the offset press blanket cylinder is good in cleaning effect, small in damage to a blanket, high in cleaning efficiency, compact in structure, small in size, convenient to transform the offset press, capable of conducting water washing and organic solvent washing respectively, capable of automatically smearing a blanket reducing agent and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of offset printing machines, and in particular relates to a quick cleaning and maintenance mechanism for a rubber cylinder of an offset printing machine. Background technique [0002] Offset printing machines have been widely used in my country and have become the mainstream of my country's printing industry. When printing, offset printing machines first transfer the printed graphics from the printing plate to the rubber cylinder, and then transfer the printing from the rubber cylinder to the paper. , which can significantly improve the printing effect. The blanket cylinder is the core of transfer printing, and its working state determines the final printing effect; the surface of the blanket cylinder is covered with a layer of expensive blanket, and the surface of the blanket is composed of synthetic rubber mainly composed of non-polar materials. Among them, the ability to absorb ink to the maximum and abso...

Problems solved by technology

[0004] When cleaning, the rubber cloth can be removed from the rubber cylinder, or the rubber cloth can not be removed, and the rubber cylinder can be directly moved or slowly rotated to clean; when cleaning by hand, generally wipe with water cloth first, and then wipe the rubber with gasoline cloth. Finally, wipe it with a clean cloth. Manual cleaning is more troublesome, inefficient, and has potential safety hazards. If you do not pay attention, it may cause additional damage to the blanket. Therefore, large printing factories now prefer to use more efficient ones. Advanced blanket automatic cleaning device, each automatic cleaning of the rubber cylinder only takes 1-2 minutes, while manual scrubbing usually takes more than 5 minutes

[0005] The automatic cleaning device is very expensive, and the automatic cleaning cloth needs to be replaced when it is used up, and the automatic cleaning cloth on the automatic cleaning device needs to rub the blanket continuously to achieve the cleaning effect. Long-term friction cleaning or improper pressure adjustment may damage the blanket. Cause irreversible damage, and it is difficult to achieve a thorough cleaning effect on relatively small impurity particles;

[0006] In addition, frequent use of organic solvents such as cyclohexanone and xylene to clean the blanket may also accelerate the aging of the blanket. It is necessary to apply a blanket reducing agent on the surface of the blanket to prolong its service life. At present, there is no automatic coating.
