Problems solved by technology

[0002] At present, there is a certain amount of unabsorbed ink on the surface of the finished product printed by the existing printing machine, which is easy to paste after touching it, so an oven is used to dry the printed matter
However, when there is a drying device to dry the printed matter, the surface of the printed matter is unevenly heated, resulting in local shrinkage and wrinkles of the printed matter; moreover, when drying, there will be a certain amount of water vapor in the oven, resulting in low drying efficiency; There will be some harmful gases produced by the volatilization of organic components in the ink, polluting the environment

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a printing machine drying device provided by the present invention includes an oven 1 and a conveyor belt 2, and also includes an air supply device 3, and the air supply device 3 is connected to the top of the oven 1 through an air supply pipe. The preferred version of the air supply device 3 is a blower, and the inlet of the blower also has a filter screen 9. The effect of filter screen 9 is to filter the large particles of impurities in the air, which ensures the safe operation of the blower. The outer layer of the air supply pipe can also be provided with an insulating layer.

[0014] The described air supply pipe is provided with a heater 4 and an ultraviolet lamp 5; the preferred scheme of the described heater 4 is an electric heating wire, and the electric heating wire generates heat to heat the air, and the hot air i...

Abstract

The invention relates to the technical field of accessories of printing machines, in particular to a drying device of a printing machine. The device comprises a stove and a transporting belt, and further comprises an air feeding device; the air feeding device is connected with the top of the stove through an air feeding pipe, and a heater and an ultraviolet radiator are arranged in the air feeding pipe; a flow equalization board is arranged above the transporting belt and provided with a plurality of round holes; and an air outlet is formed in the bottom of the stove, a rotating blade is arranged on the air outlet, and a thermometer is arranged on the stove. By means of the flow equalization board, generation of vortexes can be prevented, hot air can be evenly and gently blown to the overall surface of a printing product, the surface of the printing product is evenly heated, and generation of folds is prevented. The ultraviolet radiator is arranged, so that the sterilization and disinfection effects are achieved. The rotating blade is installed at the bottom of the stove and automatically rotates along with air flow, and air in the stove is smoothly exhausted out of the stove.

Description

technical field [0001] The invention relates to the technical field of printing machine accessories, in particular to a printing machine drying device. Background technique [0002] At present, there is a certain amount of unabsorbed ink on the surface of the finished product printed by the existing printing machine, which is easy to paste after touching, so an oven is used to dry the printed matter. However, when there is a drying device to dry the printed matter, the surface of the printed matter is unevenly heated, resulting in local shrinkage and wrinkles of the printed matter; moreover, when drying, there will be a certain amount of water vapor in the oven, resulting in low drying efficiency; There will be some harmful gases produced by the volatilization of organic components in the ink, polluting the environment. Contents of the invention [0003] The object of the present invention is to provide a drying device for printing machines that is evenly heated, anti-wri...
