Embodiment Construction

[0017] Examples, please refer to Figures 1 to 4 , a circulating ink supply system for an ink gravure printing machine, including an ink fountain 1 and an ink circulating vehicle 8 .

[0018] The ink fountain 1 is provided with an ink inlet pipe 2, and a group of through holes 5 are opened on the pipe wall of the ink inlet pipe 2. The diameter of the through holes 5 is 0.5 cm, and they are evenly arranged on the ink inlet pipe 2 every 10 cm. There is a backflow hole 6 on both sides of the inside of the ink fountain 1, and a set of overflow plates 3 for controlling the amount of ink are correspondingly arranged between the backflow holes 6. The backflow holes 6 pass through the ink outlet pipe 7 and the ink circulation vehicle 8 connected. Preferably, the ink inlet pipe 2 is a PPR pipe.

[0019] Ink circulation car 8 comprises a car body, the first ink tank 10 arranged on the car body, the stirring device installed on the side wall of the first ink tank 10, the second ink tan...

Abstract

The invention discloses a circulatory ink supply system of a printing ink photogravure press. The circulator ink supply system comprises an ink fountain and a printing ink circulating car, wherein an ink inlet pipeline is arranged on the ink fountain; a group of through holes is formed in the tube wall of the ink inlet pipeline; a reflow hole is formed inside the ink fountain; the reflux hole is connected with the printing ink circulating car by an ink outlet tube; the printing ink circulating car comprises a car body, a first ink barrel, a second ink barrel, a stirring device and a material conveying pump, wherein the first ink barrel and the second ink barrel are arranged on the car body; the stirring device is arranged on the side wall of the first ink barrel; the first ink barrel is communicated with the second ink barrel by an ink path; an inlet of the material conveying pump is connected with the bottom of the second ink barrel; and an outlet of the material conveying pump is connected with an ink inlet pipeline by an ink conveying tube. The circulatory ink supply system disclosed by the invention solves a problem that a printed finished product is caused to have chromatic aberration as the existing printing ink loses a due proportion in a printing process, effectively controls actual using amount of the printing ink, reduces waste and realizes dynamic circulation of the printing ink.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a circulating ink supply system of an ink gravure printing machine. Background technique [0002] Ink is a consumable used in large quantities in the printing industry. Due to the size of the printing factory, it is equipped with corresponding transportation methods. For small batches, boxes and barrels are used as the main carrier; for those with strong production capacity and high demand, ink turnover tanks are required. Reduce production and transportation costs. At present, most of the ink supply systems of printing machines on the market adopt the method of expanding the capacity of the ink fountain and adding the ink turnover tank. Although this method saves time and effort, but the ink is a fluid substance with strong thixotropy. If the printing time is long and there is no circulation, Ink characteristics will gradually lose their proper proportion...
