A kind of edition primary surface treating apparatus
Technical field
The utility model relates to the surface processing device of a kind of printing machinery, particularly aluminum plate foundation.
Background technology
In the printing plate-based pretreatment procedure of aluminium matter, the oil removing operation is extremely important, generally removes the grease of version primary surface with alkali lye, along with the carrying out of oil removing operation, and the Al in the degreasing fluid
3+Concentration can be more and more higher, and when reaching finite concentration, the sodium metaaluminate that alkali generates in the process of corrosion aluminium can continuous hydrolysis generate aluminium hydroxide and NaOH, and aluminium hydroxide under heating condition dehydration takes place, and generates alundum (Al.Alundum (Al is a kind of white fouling, as remains in the space of a whole page, enters subsequent processing and will be attached on the rubber roll, and the space of a whole page is caused hard defects, hinders the alligatoring of the space of a whole page, has a strong impact on product quality.Therefore, after aluminum substrate oil removing operation finishes, need the version primary surface is handled, remove the alundum (Al fouling on surface, remove residual alkali lye simultaneously.
The utility model content
The utility model provides a kind of edition basic treating apparatus, can remove the alundum (Al fouling and the residual alkali lye on aluminum substrate surface well, and is simple in structure, convenient and practical.
A kind of edition primary surface treating apparatus comprises rubber roll, hairbrush, and shower nozzle, hairbrush is by motor-driven.
Described capacity of sprinkler can be regulated.
This treating apparatus also has sewage collecting box.
Water under high pressure in the shower nozzle can be removed the alundum (Al fouling on aluminum substrate surface effectively in conjunction with hairbrush, and is simple in structure, convenient and practical, can improve the surface quality of aluminum substrate effectively.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Among the figure: 1-rubber roll, 2-nozzle, 3-hairbrush, 4-aluminum substrate, 5-degreasing unit, 6-water tank.
The specific embodiment
As shown in Figure 1, aluminium base 4 is after degreasing unit 5 oil removal treatment, under driving, rubber roll 1 moves forward, nozzle 2 ejection water under high pressures at first rinse out the alkali lye that remains in aluminum substrate 4 surfaces, avoid alkali lye that aluminum substrate 4 is carried out degree of depth corrosion, and wash away the surface hardness of matter, then scrub aluminum substrate 4 surfaces, the alundum (Al fouling that is bonded on the aluminum substrate 4 is brushed, go the alundum (Al fouling of brushing by the high pressure water washing of back nozzle 2 ejection again by hairbrush 3.The flow of nozzle 2 is adjustable, according to the water yield that the alkali lye residual condition and the alundum (Al fouling situation on aluminum substrate surface are regulated ejection, using water wisely.Further, the utility model is provided with sewage collecting box 6, with the wastewater collection of washing, can reuse after sinking clearly, handling, and has not only further reduced water consumption, reduces cost, has also avoided environmental pollution, has improved working environment.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
