Detailed Description

The following further description is made with reference to the embodiments shown in the drawings.

The ultrasonic cleaning tank of the gravure roller of the printing machine comprises a box body 1, a left carrier roller 3, a right carrier roller 2 and a plurality of wave generators 4. The interior of the box body is hollow, and the upper part of the box body is opened; during operation, the printing roller 8 can be conveyed to the interior of the box body from the opening of the box body by adopting an external mechanical arm gripper 9 (the prior art). Each wave generator is arranged on the outer wall of the box body and is used for generating ultrasonic liquid 5 from water filled in the box body; preferably, the wave generators are uniformly arranged at the lower side and the bottom of the outer wall of the box body.

The left carrier roller and the right carrier roller can be rotationally positioned in the box body around the axes thereof; the left carrier roller and the right carrier roller are parallel to each other and are horizontally arranged, and the axes of the left carrier roller and the right carrier roller are positioned on the same horizontal plane. In the embodiment, the left carrier roller and the right carrier roller are respectively driven by a group of external motors (motors are not shown in the figure), and the motors and the carrier rollers are driven by a chain wheel and chain pair; preferably, the left idler and the right idler rotate synchronously and rotate in the same direction. When the roller type synchronous rotation device works, the roller type is placed between the left carrier roller and the right carrier roller, and the left carrier roller and the right carrier roller synchronously rotate under the driving of an external motor, so that the roller type is driven to reversely rotate at a constant speed on the outer peripheral surfaces of the left carrier roller and the right carrier roller.

A liquid inlet 7 and an overflow port 6 are respectively formed in the side wall of the box body, wherein the liquid inlet is positioned on the upper side of the overflow port; the overflow port is arranged at a certain height position of the side wall of the box body according to actual conditions, and the position of the overflow port is higher than the tops of the outer surfaces of the left carrier roller and the right carrier roller. During operation, water is injected into the box body through the liquid inlet, when the water level in the box body is higher than the outer surfaces of the right carrier roller and the left carrier roller and reaches the overflow port, the overflow port discharges redundant water, so that the liquid level in the box body is kept at a certain height, the cleaning requirement of a printing roller can be met, the waste of materials can be avoided, the materials are saved, and the enterprise cost is reduced. And a liquid outlet 10 is formed in the bottom of the box body and used for discharging the ultrasonic liquid in the box body.

The utility model discloses a working method as follows:

the method comprises the steps of firstly injecting water into a box body through a water inlet, stopping injecting water after the water level is higher than the outer surfaces of a left carrier roller and a right carrier roller by a certain height, discharging redundant water through a liquid overflowing port, generating ultrasonic liquid by a generator from the water in the box body, conveying a printing roller into the box body by an external mechanical arm gripper, placing the printing roller between the left carrier roller and the right carrier roller, leaving the box body, synchronously rotating the left carrier roller and the right carrier roller at a constant speed under the driving of an external motor, and simultaneously reversely rotating the printing roller at a constant speed under the action of the left carrier roller and the right carrier roller, so that printing lines on the outer surfaces of the printing roller can be comprehensively and deeply soaked and cleaned in the ultrasonic liquid. After the roller is cleaned in the box body by the ultrasonic liquid, the external mechanical arm gripper moves into the box body again, and the roller is moved out of the ultrasonic cleaning tank, so that the ultrasonic liquid cleaning process of the roller is completed. When the ultrasonic liquid fails after being used for many times, the ultrasonic liquid is discharged to the outside of the box body through the liquid outlet for water treatment and recycling. The automatic cleaning of the printing roller is realized in the whole cleaning process, the manpower is greatly saved, and the cleaning speed and the cleaning quality of the printing roller are improved.

Finally, it should be noted that the above-mentioned embodiments illustrate only specific embodiments of the invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
