working principle

The ink filter is composed of an ink tank, an outer filter, an inner filter, an inner mesh cover, an ink inlet cover, an ink return tube, an overflow port, an ink tank cover, and the like, and an outer filter, an ink inlet cover, and an ink cover The assembly is fastened into one. The outer filter is made of a stainless steel plate having a thickness of 0.5 mm, and a small hole having a diameter of 1 mm is provided on the peripheral surface every 10 mm so that the ink flows out from the small hole. The outer filter can play a role of protecting the inner filter. When the filter is working, the magazine is pasted to prevent the inner filter from being sucked by the ink pump in the ink tank. The inner filter is made of 800-mesh nylon screen cloth (or long nylon stockings), and the upper end of the inner filter is bound to the lower port of the inner net sleeve by a wire tie. When the filter is working, one end of the right-angled ink return tube is connected to the ink groove of the printing unit of the gravure printing machine, and the other end is inserted into the inner mesh cover. The ink is passed from the ink tank of the printing unit through the ink return tube to the inner mesh cover. , and then filtered through the inner filter, then through the outer filter, and finally into the ink tank.

Structural advantages

First, an overflow port is designed on the ink filter, and Tangshan Yuyin is printed after a long time of operation. If the ink contains more impurities or the inner filter is not replaced for a long time, the ink filter is blocked, and the returned ink may overflow. The mouth flows into the ink tank to avoid the occurrence of ink flowing to the ground due to the clogging of the ink return channel. Second, the ink filter can achieve non-stop operation to replace the inner screen flexo printing. When it is determined that the inner filter needs to be replaced, the ink return tube is replaced. Turn it counterclockwise 60° so that the ink outlet is aligned with the overflow. At this time, the inner net sleeve can be extracted together with the inner filter and replaced.

Ame Mall has proved that the ink filter has the advantages of compact structure, low manufacturing cost, easy installation, easy cleaning, etc. It has certain promotion value in the printing industry.
