Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 As shown, the embodiment of the present invention provides an ink bubble suppressing device, which is used to suppress the accumulation of bubbles in the ink on the ink liquid surface when the ink in the ink return pipe is recycled to the ink container, including: a cover plate 1, a distribution plate 2 and chamber 3.

[0029] The cover plate 1 is installed on the ink container 7, and the spreading disc 2 is arranged on the side of the cover plate 1 facing the ink container, see figure 2 As shown, there are connected channels 21 distributed on the spreading plate 2, and a plurality of first through holes 22 are arranged in the channels 21.

[0030] The accommodation chamber 3 is fixed on the side of the cover plate 2 facing away from the ink container. The accommodation chamber 3 is used to contain the defoamer. The acco...

Abstract

The invention discloses a device for inhibiting bubbles in printing ink, and relates to the technical field of ink bubble treatment. The device comprises a cover plate, a scattering disc and an accommodating cavity; the cover plate is used for being arranged on a printing ink container; the scattering disc is arranged on the side, facing the printing ink container, of the cover plate, communicating channels are distributed in the dispensing disc, and multiple first through holes are formed in the channels; and the accommodating cavity is fixedly arranged on the side, back on to the printing ink container, of the cover plate, the accommodating cavity is used for containing a defoaming agent, and the accommodating cavity (3) is configured to enable the defoaming agent in the accommodating cavity to flow into the channels only when the defoaming agent in the accommodating cavity reaches the preset capacity. According to the device, the bubbles in the printing ink can be inhibited, so thatthe cyclic utilization of the printing ink is facilitated.

Description

technical field [0001] The invention relates to the technical field of ink bubble treatment, in particular to an ink bubble suppression device. Background technique [0002] In the printing production process, the coating machine is mainly used for the surface coating process production of film, paper, etc. When the coating machine uses gravure water-based ink, as the gravure water-based ink circulates and prints in the machine, It is easy to generate a large number of air bubbles, which are drawn back from the ink recovery pump to the ink container, and accumulate on the top of the ink. The main components of gravure printing water-based ink are soluble resin and water. Due to its own surface tension, drying characteristics and other properties, the speed of bubble self-rupture is extremely slow, and it tends to dry and agglomerate before rupture, forming a shell layer, blocking subsequent bubble rupture , as the ink cycle progresses, the ink under the cover layer is conti...
