Problems solved by technology

[0005] There are problems: ① The ink in the ink cavity is not clean, especially the ink in the ink supply pipeline cannot be recycled
②Because the ink return is not clean, there is a lot of residual ink in the ink chamber and the pipeline, resulting in a long cleaning time, a large amount of cleaning water, and serious pollution
③Shutdown for ink return, water cleaning, and ink production each step requires manual operation, which takes a long time for cleaning, which wastes time and affects production efficiency

Embodiment 1

[0034] The present invention provides such figure 1 , 2 , shows a printing machine ink cleaning equipment for carton packaging production, including an ink accumulation chamber 6, a clear water bucket 7, an ink bucket 8, an ink filling pump 9 and an ink return pump 10, and its specific structure is the prior art, here Without going into details, the ink accumulating chamber 6 is a self-contained equipment of the printing machine, which is equipped with two sets of ink return ports and one set of ink filling ports. The clear water bucket 7 is used to store cleaning water and is equipped with a drain pipe, and the ink bucket 8 is used to store ink. , which is equipped with an ink adding port, an ink return pipe is connected between a port of the ink return pump 10 and the ink return port of the accumulated ink chamber 6, and the ink return pipe is composed of a first ink return pipe 11 and a second ink return pipe 12, The first ink return pipe 11 and the second ink return pipe ...

Embodiment 2

[0040] When utilizing the equipment in embodiment 1 to clean the ink accumulation chamber 6 of the printing press, the steps are as follows:

[0041] 1. Shutdown ink return process: the ink filling steering valve 18 is energized and turned to the ink returning direction. At this time, the three pipes of the ink feeding pipe 14, the first ink returning pipe 11 and the second ink returning pipe 12 return the ink at the same time, and the speed is accelerated. The ink tube 14 is changed back to the ink pipeline, and there will be no residual ink in the pipeline;

[0042]2. Add water to dilute the ink and return: After the ink is returned, the PLC automatically controls to enter the process of adding water to dilute and return the ink, and the PLC controls to open the fifth solenoid valve 5, and the ink chamber enters the clear water to dilute the ink and return;

[0043] 3. Circular flushing: After adding water to dilute the ink return time, the PLC controls to close the fifth so...

Embodiment 3

[0047] When utilizing the equipment in embodiment 1 to clean the ink accumulation chamber 6 of the printing press, the steps are as follows:

[0048] 1), one end of the first ink return pipe 11 and the second ink return pipe 12 is communicated with the two ends of the ink accumulation chamber 6, and the other end is communicated with a port of the ink return pump 10, and the ink return pump 10 is connected The other port communicates with the clear water barrel 7 and the ink barrel 8 through the three-way pipe A13 with the first solenoid valve 1 and the second solenoid valve 2;

[0049] 2), connect the ink filling pipe 14 between a port of the ink filling pump 9 and the ink filling port of the ink accumulating chamber 6, then connect the three-way pipe B15 with the third solenoid valve 3 and the fourth solenoid valve 4 with the Another port of the ink pump 9, the clear water barrel 7 and the ink barrel 8 are connected;

[0050] 3), one end of the tap water pipe 16 is communic...

Abstract

The invention discloses printing machine ink cleaning equipment for carton packaging production and a cleaning process of the printing machine ink cleaning equipment. The printing machine ink cleaning equipment comprises an ink accumulation cavity, a clean water barrel, an ink barrel, an ink feeding and an ink return pump, wherein an ink return pipe communicates between one port of the ink return pump and an ink return port of the ink accumulation cavity, the other port of the ink return pump communicates with the clean water barrel and the ink barrel through a three-way pipe A, a first electromagnetic valve and a second electromagnetic valve are respectively mounted at two ends of the three-way pipe A, an ink feeding pipe communicates between one port of the ink feeding pump and the ink feeding port of the ink accumulation cavity, the other port of the ink feeding pump communicates with the clear water barrel and the ink barrel through a three-way pipe B, and a third electromagnetic valve and a fourth electromagnetic valve are installed at the two ends of the three-way pipe B respectively. According to the printing machine ink cleaning equipment, two processes of diluting and reclaiming ink and circularly flushing are added in the cleaning process, residual ink in an ink cavity and a pipeline is basically recycled, and meanwhile, the cleaning water amount and the cleaning time are greatly reduced through circular flushing, and the sewage generation amount is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ink cleaning devices for printing machines in the packaging industry, in particular to an ink cleaning device for printing machines used in carton packaging production and a cleaning process thereof. Background technique [0002] At present, in related technologies, various printing machines have also appeared in various fields one after another, and the pigments used are also different. For example, printing machines use ink as pigments. It is a uniform mixture composed of other substances, which can be printed and dried on the printed body. It is a paste-like adhesive body with color and certain fluidity. [0003] Printing machine existing cleaning [0004] Function: The general procedure is: 1. Shut down to return the ink and flow naturally. The time can be set. 2. Clean with water, open the clean water gate valve, enter the ink chamber and pipeline, and clean with water flow. [0005] Existing pro...
