Description

Technical Field

[0001] The utility model relates to the technical field of printing cleaning equipment, in particular to a roller cleaning spray main machine. Background Art

[0002] The slow drying of ink on the paper of high-speed printing machines can easily cause the machine to stop and stick to the bottom, thus producing waste products. Although the use of quick-drying ink or quick-drying fountain solution can solve the problem of ink sticking to books and periodicals during the printing process, after the printing is stopped for a period of time, the quick-drying ink will produce crusting ink on the PS plate, and the problem of dirty spots on the PS plate that cannot be solved by the fountain solution will appear when the machine is restarted after stopping for a period of time. In order to spray the cleaning and protective liquid on the PS plate and the rubber roller, the operator often needs to use a handheld pneumatic or electric spray gun from the first seat to the last seat of the multi-color machine to spray the cleaning and protective liquid on one side of the PS plate and the rubber roller. The cleaning efficiency is low, the uneven spraying easily causes paper waste, and the labor intensity is high. For this reason, the applicant has proposed a utility model patent with the authorization announcement number of CN216761218U, which discloses a printing machine plate roller cleaning and protective spray device. The nozzle on the pipeline automatically sprays the PS plate and rubber roller cleaning and protective liquid of the multi-color machine seat evenly on the rubber roller and the PS plate, solving the problem of dirty ink spots on the PS plate when the machine is stopped for a period of time and then restarted. When in use, the device often needs to be equipped with a pressure storage tank for storing the cleaning and protection liquid, a compressor for providing air pressure, and various pipe and valve components.

[0003] The prior art adopts a fixed installation structure, in which the pressure storage tank and the compressor are fixedly installed in the main engine housing. When the cleaning protection liquid is used up, the pressure storage tank is often required to be disassembled and refilled, which is not convenient and is not conducive to the subsequent maintenance of the pressure storage tank, the compressor and other components.
