Sheet-fed printing press ink fountain with fluorocarbon resin coating and color separating device

Abstract

The invention discloses a printing press ink fountain. The printing press ink fountain comprises at least one ink fountain blade 5, at least one color separating piece 4 and at least one color separating piece support 9 installed between every two adjacent ink fountain blades 5, wherein a groove is arranged in the middle of each color separating piece support 9. The color separating piece 4 is installed in the groove, a gap is reserved between the bottom of the color separating piece 4 and the groove bottom, the upper end of the tail portion is fixedly connected with a rotating support point 2 in the groove, the lower end of the tail portion is connected with a position adjustor consisting of an elastic element 1 and a top column 3 in the groove, and a straight-line distance between the color separating piece 4 and an ink fountain roller 6 is confirmed and meets the requirement for tight adhesion through automatic positioning of the rotating support point 2 and an ink fountain roller 6. A fluorine plastic layer is coated on the surface of a metal part in the device. The color separating device of the printing press ink fountain has the advantages of being good in color separating effect, long in service life, easy to clean, corrosion-resisting and the like.

Description

technical field [0001] The invention relates to an ink fountain color separation device for a sheet-fed printing machine, in particular to an ink fountain color separation device for a printing machine capable of storing multi-color inks in one ink fountain. Background technique [0002] A printing machine is a machine used to print text and images. With the progress of the times, people's requirements for color have gradually increased. Single-color printing has long been unable to meet people's needs. Multi-color printing machines have emerged as the times require, which means that color printing Increased precision requirements. [0003] Traditional printing machines use one ink fountain to store inks of more than two colors at the same time to print products with special effects, and realize multi-color printing through the ink fountain color separation device composed of color separation sheets. The existing ink fountain color separation devices mainly include the follo...

Problems solved by technology

When workers clean, they need to disassemble the parts to be cleaned first, then soak the parts in cleaning solvent for a period of time, and then scrub them vigorously with a spatula and solvent. This cleaning method is inefficient, and the plastic inner film in the color separation film device will also Swelling and deformation due to long-term immersion will also have adverse effects on the operating environment
