Sealed type oil supply device

Abstract

The invention provides a sealed type oil supply device. The sealed type oil supply device comprises a side plate, a metal roller, a rubber roller, a ceramic roller for supplying oil, and a sealed type oil groove; the metal roller, the rubber roller, the ceramic roller and the sealed type oil groove are arranged on the side plate; the rubber roller is respectively tangent to the metal roller and the ceramic roller, and can be arranged on the side plate in a way of moving up to down; the sealed type oil groove is arranged at the right side of the ceramic roller, and the left side of the sealed type oil groove, facing the ceramic roller, is provided with an inwards-concave oil storage groove; an opening of the oil storage groove is adapted to the circular surface of the ceramic roller; and scrapping cutters are respectively arranged at the upper side and the lower side of the opening of the oil storage groove. Compared with the prior art, the sealed type oil supply device provided by the invention adopts the sealed type oil groove to supply oil, therefore, the loss in volatilizing of the gloss oil can be greatly reduced, and the requirement on sanitation and environmental protection can be met better.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a closed oil supply device for varnishing printed matter. Background technique [0002] In the rotary printing machine, after the web is printed in color, in order to make the surface of the printed matter more glossy and protect the printed pattern more durable, the paper is usually treated with varnish. In the prior art, the oil supply device on the printing press is an open type, which includes an oil tank with an open upper end and an oil supply roller rotatably arranged in the oil tank, and part of the oil supply roller is immersed in the varnish in the oil tank. [0003] However, since the varnish usually contains volatile solvents, the existing technology uses an open oil tank to volatilize a large amount of solvents into the air of the workshop, which increases the loss of varnish on the one hand, and on the other hand, the volatilized solvents not only pollute the air i...

Problems solved by technology

[0003] However, since the varnish usually contains volatile solvents, the existing technology uses an open oil tank to volatilize a large amount of solvents into the air of the workshop, which increases the loss of varnish on the one hand, and on the other hand, the volatilized solvents not only pollute the air in the workshop Air and equipment surfaces, but also seriously affect the health of personnel in the workshop
