Detailed Description
The automatic scraper chamber cleaning device 100 of the printing machine shown in fig. 1 comprises a scraper chamber body 110 with ink-jet and ink return pipelines, and the scraper chamber 110 and a flow cup 120 with a float switch 121 are connected in parallel on a water inlet pipeline 130. The float switch 121 is used to control the amount of water in the sensing flow cup 120.
The water inlet line 130 includes a main water line 131 and two water distribution lines 132 and 133, the main water line 131 is provided with a water pump 131a for controlling the opening and closing of water flow, a manual valve 141 for distributing water flow and an electromagnetic valve 142 for controlling the water inlet and closing of the two water distribution lines 132 and 133 are installed at the connection end of the two water distribution lines 132 and 133 and the main water line 131, and the water distribution line 132 is further connected with an electromagnetic valve 143 for controlling the water inlet and closing of the flow cup 120.
The doctor chamber 110 is connected to the water distribution line 133 through an air control valve 150, and the doctor chamber 110 is connected to an ink jet line 160, and the ink jet line 160 has an ink jet head 161 and a diaphragm pump 162 for supplying a pumping force.
The doctor blade chamber 110 is also connected to a return line 170 via a number of suction heads 171, to which return line 170 is also connected a membrane pump 172 for providing a pumping force.
The other ends of the ink jet pipeline 160 and the ink return pipeline 170 are both connected with a control valve 180, the control valve 180 comprises three valve ports 181, 182 and 183, and the valve port 181 is connected with an external wastewater recovery device (not shown in the figure) through a pipeline; the valve port 182 is connected to an external ink recycling device (not shown) through a pipeline for recycling the ink in the ink pipeline 170; the valve port 183 is connected to an external ink recycling device (not shown) through a pipeline, and is used for recycling the recycled ink through the inkjet pipeline 160.
Because of having the above structure, the utility model discloses a theory of operation lies in:
when printing, the water pump 131a and the solenoid valves 142 and 143 are closed, the valve port 181 of the control valve 180 is closed, and the valve ports 182 and 183 are opened, so that printing is performed, after ink in an ink recycling and circulating device (not shown) is sprayed into the doctor blade chamber 110 through the inkjet head 161 via the inkjet pipeline 160, the remaining ink enters the ink recycling and circulating device (not shown) via the ink suction head 171, and then flows back to the ink recycling and circulating device (not shown), thereby forming a circulating inkjet loop.
Nevertheless through long-time use, still can have remaining ink in scraping knife chamber 110 and pipeline, the time of having of a specified duration can damage and scrape knife chamber 110, just this moment need regularly wash the incomplete ink in scraping knife chamber 110 automatically, and the utility model discloses a washing includes following two steps:
first, the residual ink in the scraper chamber 110 and the pipeline and in the pump body is recovered, and at this time, the air control valve 150 is closed, the water pump 131a and the electromagnetic valves 142 and 143 are opened to fill the water in the flow cup 120, and then the electromagnetic valves 142 and 143 are closed.
Then, the residual ink recycling operation is performed, the electromagnetic valve 143 connected to the flow cup 120 for controlling the water inlet and the water closing is opened, the pneumatic control valve 150 is opened, the valve port 181 is closed, the residual ink in the scraper cavity 110, the pipeline and the pump body is flushed by the water in the flow cup 120, and the liquid after the flushing is circulated is discharged into an ink recycling device (not shown).
After waiting for a while for the water in the flow cup 120 to flow out, the solenoid valve 143 is closed, the solenoid valve 142 and the pneumatic valve 150 are opened, and the valve port 181 is opened and the valve ports 182 and 183 are closed.
Then, the water pump 131a is turned on, so that the water flows into the doctor cavity 110 through the water distribution pipeline 133, and is discharged into an external wastewater recovery device (not shown) through the ink return pipeline 170 and the diaphragm pump 172 through the valve port 181, and after a few minutes of cleaning, the electromagnetic valve 142 and the water pump 131a are turned off, thereby completing cleaning.
Owing to possess above-mentioned structure, the utility model has the advantages of:
through the water diversion setting mode of the water inlet pipeline, the recovery of residual ink is realized, and meanwhile, the automatic cleaning of the residual ink of the scraper cavity and the pipeline is realized.
