The utility model relates to the technical field of ultrasonic cleaning of materials, in particular to an ultrasonic cleaning device for
relief printing plate materials, which comprises a shell, a cleaning frame, an
ultrasonic generator, two water pipes, a water pump, a water tank, a mounting block and a
filter element, the cleaning frame is connected with the two water pipes, and the
ultrasonic generator is mounted in the shell. A water tank is clamped between the two water pipes, a water pump is arranged on one
water pipe, a mounting block is clamped in the water tank, and a
filter element is fixedly connected in the mounting block. The water pump is started, the water pump pumps water in the cleaning frame through the
water pipe and pumps the water into the water tank, meanwhile, the pumped water is filtered through the
filter element, and the filtered water returns to the cleaning frame from the other
water pipe, so that a
water circulation purification
system is formed, the ultrasonic cleaning effect can be maintained, and it is avoided that when the water pump is taken out, the water pump is damaged. Part of the impurities are deposited on the material.
