Description

Powder spraying recovery device of printing machine

Technical Field

The application relates to the technical field of printing auxiliary equipment, in particular to a powder spraying recovery device of a printing machine.

Background

When the printing machine is used for multi-color printing of paper, ink on the paper subjected to multi-color printing is thick in accumulation, so that the ink on the paper is difficult to dry quickly; and the paper output end of the printer rapidly outputs the printed paper, and the printed paper is stacked at the paper output end of the printer, and the stacked paper is easy to generate ink scratch due to the incompletely dried ink, so that characters and patterns on the paper are smeared. In order to prevent the characters and patterns on the paper from being scratched by the incompletely dried ink, a worker usually installs a powder sprayer at the paper output end of the printing machine, and sprays a layer of printing powder onto the printed surface of the printed paper through the powder sprayer to accelerate the drying of the ink on the surface of the paper.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: because the printing powder sprayed by the powder sprayer is difficult to be completely adhered to the printing surface of the paper, when the powder sprayer prints and sprays the paper, part of the printing powder is easy to float in the air, thereby polluting the environment.

SUMMERY OF THE UTILITY MODEL

In order to collect the printing powder spray that drifts in the air, make the difficult polluted environment of printing powder spray that drifts, this application provides a printing machine recovery unit that dusts.

The application provides a recovery unit sprays powder adopts following technical scheme:

the utility model provides a printing machine recovery unit that dusts, is including setting up the duster at printing machine play paper end, be equipped with the collection box on the printing machine, main filter chamber has been seted up in the collection box, be equipped with the baffle in the main filter chamber, the baffle will main filter chamber separates into first filter chamber and second filter chamber, the lower extreme of baffle with leave the clearance between the inner diapire of main filter chamber, be equipped with the subassembly of bleeding on the collection box, the subassembly of bleeding be suitable for with the air suction of printing machine play paper end in the first filter chamber, be equipped with spray assembly in the collection box, spray assembly is suitable for flowing through first filter chamber the air of second filter chamber filters, the venthole has been seted up on the collection box, the venthole with the second filter chamber is linked together.

By adopting the technical scheme, after the powder sprayer sprays the printed paper at the paper outlet end of the printer, the air at the paper outlet end of the printer is extracted by the air exhaust assembly, so that the printed powder spraying floating at the paper outlet end of the printer is guided into the first filter cavity along with the air, the air mixed with the printed powder spraying flows through the first filter cavity and the second filter cavity and is subjected to dust fall and filtration in sequence by the spraying assembly, clean air is discharged to the outside along the air outlet hole, and the scattered printed powder spraying is accumulated in the first filter cavity and the second filter cavity, so that the printed powder spraying is not easy to float in the air to pollute the environment; the printing powder spraying in the air is collected in the first filter cavity and the second filter cavity, so that the recovery work of the printing powder spraying is facilitated for workers, and the use waste of the printing powder spraying is reduced; air that has the printing and dusts lets in behind the first filter chamber will follow the leading-in second filter chamber in clearance, then along the interior roof of second filter chamber discharge to the external environment in to make the air have longer flow length in the collection box, improved the dust fall plumpness of spray assembly to the air, thereby carried out effectual recovery to the printing of wafting in the air and dusting.
