Description

Technical Field

[0001] The utility model relates to the technical field of coated paper machines, in particular to a spray device for producing coated paper. Background Art

[0002] During the production of coated paper, the non-coated surface of the coated paper is usually sprayed and moistened according to the drying process requirements, from the time the coated paper passes through the coating air drying box to the time the coated paper enters the drying cylinder for drying, so as to improve the drying uniformity and flatness of both sides of the coated paper entering the last drying cylinder process section. At this time, the spray moistening is usually carried out by spraying the surface of the coated paper with a spray device equipped with air atomizing nozzles distributed at equal intervals, so as to ensure continuous and uniform moistening of the surface of the coated paper. The air atomizing nozzles are generally connected by threads and arranged at equal intervals on the round tube to ensure full coverage and uniformity of the spray, and the distance from the spray device to the coated paper is adjusted by mechanisms or equipment such as cylinders or mechanical connecting rods, so as to meet the production requirements of different coated papers. In addition, a mist suction duct is arranged just above the contact between the water mist and the coated paper, and the mist suction duct sucks away the floating excess water mist to prevent the floating water mist from condensing on nearby equipment.

[0003] The water mist of the spray device is sprayed from the nozzle, and the water mist acts on the surface of the spray-coated paper. Different coated papers require different amounts of water, but the distance between the existing spray device and the spray-coated paper is fixed, which makes the spraying range of the water mist fixed.
