Apparatus for washing off ink in flexographic printing press and method for washing off ink in flexographic printing press

摘要

An apparatus includes a washing water supplying path connected to an ink chamber, including a seal blade and a doctor blade slidably contacting an outer circumference of an anilox roll; a washing water supplier for supplying washing water to an inside of the ink chamber through the washing water supplying path; a supplying path opening/closing device that opens and closes the washing water supplying path; a washing water recovering paths connected to the ink chamber; a suction recovering device that recovers the washing water in the ink chamber by suction through the washing water recovering path; and a controller that controls operations of the washing water supplier, the supplying path opening/closing device, and the suction recovering device. The control mode includes a decompression control mode in which the seal blade is elastically deformed towards the ink chamber by decompressing the inside of the ink chamber by recovering the washing water.

主权项

1. An apparatus for washing off an ink in a flexographic printing press, the apparatus comprising:
a first washing water supplying path that is connected to an ink chamber, the ink chamber including a seal blade and a doctor blade being in slidable contact with an outer circumference of an anilox roll; a second washing water supplying path that supplies a top surface of the seal blade with washing water; a washing water supplier that supplies washing water to an inside of the ink chamber through the first washing water supplying path; a supplying path opening/closing device that opens and closes the first washing water supplying path; a washing water recovering path that is connected to the ink chamber; a suction recovering device that recovers the washing water in the ink chamber by suction through the washing water recovering path; and a controller that controls operations of the washing water supplier, the supplying path opening/closing device, and the suction recovering device accordance with a predetermined control mode, wherein the control mode comprises a decompression control mode in which the seal blade is elastically deformed towards the ink chamber by decompressing the inside of the ink chamber by recovering the washing water by suction generated by activating the suction recovering device and closing the first washing water supplying path by the supplying path opening/closing device.
