Flow controllable ink pumping device for printing machine and using method thereof

Abstract

The invention discloses a flow controllable type ink pumping device for a printing machine, and belongs to the technical field of ink pumping devices for printing machines. An ink pumping pump is fixed at the top of the right side wall of an inner cavity of a box body, an ink box is fixed at the bottom of the inner cavity of the box body, a throttling device is fixed at the right side of the top of the ink box in a communicating mode, the left end of an ink suction pipe penetrates through the right side wall of the box body and is connected with the input end of the ink pumping pump, the bottom of the right side wall of the box body is fixedly connected with an ink discharge pipe, the left end of the ink discharge pipe penetrates through the box body and the ink box and extends to an innercavity of the ink box, the left side of the top of the ink box is fixedly connected with an air guide pipe, the left side of the top of the box body is fixedly provided with a purifier, volatile gasin ink can be effectively filtered and absorbed, the flow quantity and the flow rate of the circulating ink can be adaptively controlled, and an ink discharge channel can be automatically closed whenthe flow quantity is large so as to have good uniformity.

Description

technical field [0001] The invention relates to the technical field of an ink pumping device for a printing machine, in particular to a flow controllable ink pumping device for a printing machine and a method for using it. Background technique [0002] With the wide application of printing machines, printing machines need to ensure the continuous supply of printing inks during use. The inks also contain a certain amount of volatile organic compounds, which will produce benzene, benzene series and ozone during the curing and drying process. These exhaust gases are harmful to the human body, but the current ink absorbing devices on the market cannot effectively absorb and filter volatile gases when absorbing ink. Reasonable control of ink flow will easily cause discontinuity and inhomogeneity of ink absorption. Therefore, we propose a flow-controllable ink pumping device for printing presses and its usage method. Contents of the invention [0003] The object of the present ...
