Viscosity controller printing ink reflux device

Abstract

The invention discloses a viscosity controller printing ink reflux device. The viscosity controller printing ink reflux device comprises an ink groove, a fixed seat and a printing ink viscosity controller. A reflux inlet is formed in the side surface of one end of the ink groove in a communicating mode, a printing ink barrel is arranged below one end of an ink absorbing pipe, a first cleaning barrel is connected to one side of the printing ink barrel, a second cleaning barrel is arranged on one side of the ink groove, a sliding seat is slidably installed on the upper part of the fixed seat, afirst air cylinder arranged horizontally is installed on the upper part of the fixed seat, a second air cylinder is vertically installed at the upper end of the sliding seat, and the ink absorbing pipe and an ink outlet pipe are correspondingly and fixedly connected to a Z-shaped bracket. According to the viscosity controller printing ink reflux device, after printing ink is used, the interior ofa pipeline and the interior of a pneumatic diaphragm pump can be cleaned timely; and during cleaning, operation is carried out directly through an operating plate, one end of the ink absorbing pipe isinserted into the first cleaning barrel, one end of the ink outlet pipe is inserted into the second cleaning barrel, direct touch operation cleaning is carried out without holding in hand, and usingis convenient.

Description

technical field [0001] The invention relates to the technical field of ink viscosity controllers, in particular to an ink return device for viscosity controllers. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of pigments, linking materials, additives and solvents. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. Inks mainly include solvent inks, water-based inks, UV inks, screen printing inks, and offset printing inks. [0003] The solvent contained in the ink is highly volatile, so when in use, it is necessary to use an ink viscosity controller to...

AI Technical Summary

Problems solved by technology

[0004] Many existing ink viscosity controllers do not have a cleaning device in the reflux device. When they are stopped for a long time or used intermittently, it is easy to cause dry blockage or excessive viscosity condensation blockage, which will affect the next use. For example, a Chinese patent CN208038026 discloses a This kind of ink extraction and return sealing cover integrated device, although it is sealed, it will easily cause clogging after a long period of non-use

[0005] The existing ones are also equipped with manual cleaning, but this method manually moves the ink suction tube and the ink outlet tube for transfer cleaning, which is easy to cause ink to spill, and the operation is inconvenient, and the ink is easy to stain the hands or clothes, which is inconvenient to operate
