DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a printing roller cleaning device. Figure 1-3A printing roller cleaning device comprises a shell 2, an ultrasonic cleaning tank 1 is installed on the inner side of the shell 2, a printing roller 4 and a sponge roller 5 are installed in the ultrasonic cleaning tank 1, the printing roller 4 and the sponge roller 5 are ultrasonically cleaned by the ultrasonic cleaning tank 1, driving components 3 are installed on both sides of the ultrasonic cleaning tank 1, the driving components 3 include two brackets 301 moving along Y, a rotating roller shaft 6 is installed on the bracket 301, the printing roller 4 and the sponge roller 5 are respectively sleeved on the corresponding rotating roller shaft 6, the sponge roller 5 and the printing roller 4 are rubbed against each other, so that the sponge roller 5 can flexibly scrub the printing roller 4 to avoid damage to the printing roller, the distance between the two brackets 301 can be adjusted to change the distance between the printing roller 4 and the sponge roller 5, and it can be suitable for printing rollers of different diameters, and two pairs of rotating rollers are rotatably installed on the bracket 301 The roller 6 is supported by a supporting roller 302, and the two supporting rollers 302 are connected by a chain transmission unit 8. The supporting roller 302 drives the rotating roller 6 to rotate, so that the printing roller 4 and the sponge roller 5 can be rotated. The rotating roller 6 can also be quickly removed to replace the printing roller 4 and the sponge roller 5. Both sides of the ultrasonic cleaning tank 1 are also equipped with driving devices 303 that move along the Z axis. The driving device 303 and the corresponding two supporting rollers 302 are driven by a belt transmission unit 304. The driving device 303 moves along the Z axis to adjust the tension of the belt on the belt transmission unit 304, so that the belt is tightened to ensure the synchronous rotation of the supporting rollers 302, thereby realizing the same-direction rotation of the printing roller 4 and the sponge roller 5, and realizing the flexible scrubbing of the printing roller 4 by the sponge roller 5 to avoid damage to the printing roller.

[0022] By adopting the above technical scheme, the printing roller 4 and the sponge roller 5 are ultrasonically cleaned by the ultrasonic cleaning pool 1. At the same time, the printing roller 4 and the sponge roller 5 that rotate and contact in the same direction are rubbed against each other, which can improve the cleaning efficiency, ensure the cleaning effect, shorten the cleaning time, and greatly reduce the damage of ultrasonic waves and friction to the printing roller 4.

[0023] Reference Figure 3 The ultrasonic cleaning tank 1 includes a cleaning tank 101 filled with ultrasonic cleaning liquid, an ultrasonic device 102 is installed at the bottom of the cleaning tank 101, and a drain valve is installed on the cleaning tank 101, which can be connected to an external sewage treatment device to facilitate the sewage to be discharged to the sewage treatment device for sewage treatment. The ultrasonic device 102 is composed of components such as an ultrasonic generator, a transducer and a vibrator. The ultrasonic generator generates a high-frequency electrical signal, the transducer converts the electrical signal into mechanical vibration, and the vibrator transmits the mechanical vibration to the cleaning tank 101, thereby generating ultrasonic waves to ultrasonically clean the printing roller 4 and the sponge roller 5.

[0024] Reference Figure 2Inspection doors are installed on both sides of the shell 2 to facilitate the inspection and maintenance of the drive component 3. The drive device 303 includes a servo electric cylinder 3031 installed on the shell 2. The servo electric cylinder 3031 is slidingly installed with a power motor 3032. The power motor 3032 and the corresponding two supporting rollers 302 are both equipped with pulleys of a belt drive unit 304. The matching belt is used for long-distance transmission adjustment, which can be suitable for the cleaning spacing requirements of different printing rollers 4.

[0025] Reference Figure 2 The inner sides of the two groups of brackets 301 are driven and installed with an adjustment component 7 installed along the Y-axis. The adjustment component 7 includes a bidirectional screw 701 rotatably installed in the shell 2. Both ends of the bidirectional screw 701 are respectively threaded through the corresponding brackets 301 to realize the two brackets 301 moving towards each other. A guide rod 702 is also installed on the lower side of the bidirectional screw 701 in the shell 2. The guide rod 702 passes through the bracket 301 and is slidably connected to the bracket 301. A chain transmission unit 703 is driven and installed between the two bidirectional screws 701. The chain transmission unit 703 is used to realize the synchronous rotation of the two bidirectional screws 701 to complete the synchronous movement of the brackets 301 on both sides. The ends of the bidirectional screws 701 pass through the shell 2 and are connected with a hand wheel to facilitate manual adjustment by the staff.

[0026] The implementation principle of a printing roller cleaning device in the embodiment of the present application is as follows: first, the printing roller 4 to be cleaned is placed on the supporting roller wheel 302, and the distance between the two brackets 301 is adjusted by the adjusting component so that the spacing between the ultrasonic cleaning tank 1 and the rotating roller shaft 6 is adapted to the diameter of the printing roller 4. Then, the driving device 303 is started, and the supporting roller wheels 302 on both sides are driven to rotate synchronously by the driving device 303. At the same time, the ultrasonic device 102 generates ultrasonic waves to vibrate the ultrasonic cleaning liquid in the cleaning tank 101, so that the printing roller 4 is cleaned under the action of ultrasonic waves. Driven by the supporting roller wheel 302, the printing roller 4 and the sponge roller 5 rotate synchronously and contact and rub against each other to achieve flexible scrubbing of the ultrasonic cleaning tank 1. During the cleaning process, the cleaning effect can be optimized by observing the cleaning effect and adjusting the parameters of the driving device 303. Finally, the drain valve is opened to discharge the cleaned sewage to the external sewage treatment equipment for further treatment. The entire cleaning process is efficient, environmentally friendly and does not damage the ultrasonic cleaning tank 1.
