Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing equipment, and more specifically, to an ultrasonic hopper. Background Art

[0002] In gravure printing, the ink in the hopper needs to be coated onto the surface of paper or film through an anilox roller. Since the surface of the anilox roller is covered with tiny mesh holes, a part of the ink will always remain in the mesh holes of the anilox roller during the coating and printing process. After the anilox roller is used for a long time, this part of the ink will gradually solidify, thereby affecting the coating and printing operation. In actual operation, the anilox roller needs to be cleaned after about 100,000 meters of coating and printing. Currently, the anilox roller is cleaned by stopping the machine and disassembling it. It can be seen that the current equipment has to be shut down every 100,000 meters of printing, which greatly affects the efficiency of coating and printing. Therefore, it is urgently needed to improve this. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide an ultrasonic hopper. By arranging an ultrasonic vibrator in the hopper, the hopper becomes an ultrasonic cleaning device. The ink is used as a cleaning agent, and the anilox roller can be cleaned when the anilox roller is working, thereby reducing the probability of cell blockage and the number of times the anilox roller is disassembled and cleaned.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses an ultrasonic hopper, comprising an outer shell, an inner liner is fixed inside the outer shell, a mounting cavity is provided between the outer shell and the inner liner, an ultrasonic generator and a plurality of ultrasonic vibrators are installed in the mounting cavity, the ultrasonic vibrators abut against the bottom of the inner liner, and a base is connected to the lower part of the outer shell.

[0006] Furthermore, the inner liner includes a side panel and a bottom panel, the side panel and the bottom panel are transitioned through rounded corners, and the thickness of the bottom panel is smaller than the thickness of the side panel.

[0007] Furthermore, a plurality of grooves are provided at the lower portion of the bottom plate, and the upper portion of the ultrasonic vibrator is inserted into the grooves and abuts against the tops of the grooves.

[0008] Furthermore, a mounting hole is provided at the lower portion of the shell, a cover plate is fixed in the mounting hole, and the ultrasonic vibrator is mounted on the upper portion of the cover plate.

[0009] Furthermore, a plurality of machine feet are fixed to the lower portion of the shell, and a limiting groove corresponding to the machine feet is provided on the upper portion of the base, and the machine feet are inserted into the limiting groove for limiting.

[0010] Furthermore, there is a gap between the lower portion of the shell and the upper portion of the base.

[0011] Furthermore, the inner wall of the shell is provided with sound insulation cotton, and the sound insulation cotton is closely attached to the side wall of the inner tank.

[0012] Furthermore, a sealing ring is fixed to the upper portion of the base, and the lower portion of the shell abuts against the upper portion of the sealing ring.

[0013] The beneficial effects of the utility model are:

[0014] 1. When in use, start the ultrasonic generator without stopping the machine every 5000-10000 meters of printing. The ultrasonic vibrator will emit high-frequency vibration to drive the inner liner and the ink inside the liner to vibrate, so that the cells on the surface of the anilox roller can be cleaned online, which can effectively reduce the probability of cell blockage on the surface of the anilox roller and reduce the number of times the anilox roller is disassembled and cleaned, greatly improving the efficiency of gravure printing;

[0015] 2. The base and the shell are of detachable design. By setting the base and cooperating with the machine feet and the limit grooves, the shell can be supported and the stability of the shell when the ultrasonic vibrator is working can be improved. By setting the machine feet made of rubber material, the transmission of vibration of the shell to the bottom plate can be weakened, and the stability is good. BRIEF DESCRIPTION OF THE DRAWINGS
