Description

Technical Field

[0001] This utility model relates to the field of ink printing technology, specifically an ink printing roller cleaning device. Background Technology

[0002] In the ink printing industry, web printing presses are widely used printing equipment, primarily utilizing web paper as the printing substrate. Existing web printing equipment typically includes a feeding device, a printing unit, and a folding device. The feeding device is responsible for placing and gradually releasing the web paper to be printed; this process is usually powered by a motor-driven take-up roller. The printing unit is responsible for printing on the web paper fed by the feeding device. However, during the printing process, the printing rollers inevitably become contaminated with ink. Over time, the accumulation and solidification of ink can affect print quality and equipment performance. Therefore, regularly cleaning the printing rollers is an important step in maintaining the normal operation of the printing equipment.

[0003] Patent application number 202020208637.0 discloses a printing roller cleaning device, including a base, a cleaning housing installed on the top outer wall of the base, and hydraulic cylinders installed on both sides of the bottom inner wall of the cleaning housing. An arc-shaped plate is installed on the top outer wall of the hydraulic cylinders. An electric motor is installed on one outer wall of the cleaning housing, and a rotating shaft is installed at the output end of the electric motor. A locking bolt is rotatably connected to the other outer wall of the cleaning housing by a thread, and a rubber is rotatably connected to one side of the outer circumference of the locking bolt by a bearing.

[0004] Currently, although some printing roller cleaning devices have been developed, such as the printing roller cleaning device disclosed in patent application number 202020208637.0, which cleans the printing roller through an arc-shaped plate driven by a hydraulic cylinder and a rotating shaft driven by an electric motor, these devices still have some shortcomings in practical applications. Specifically, existing cleaning devices often cannot drive the printing roller to rotate during the cleaning process, resulting in the cleaning device itself having to move or rotate to rub against the surface of the printing roller to remove ink. While this method can accomplish the cleaning task to a certain extent, the cleaning efficiency and effect are often limited due to the lack of active rotation of the printing roller. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an ink printing roller cleaning device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ink printing roller cleaning device, comprising a cleaning tank, a first servo motor mounted on the left side of the cleaning tank, a first rotating shaft mounted on the output end of the first servo motor, the first rotating shaft being rotatably connected to the interior of the cleaning tank, a cleaning roller mounted on the outer surface of the first rotating shaft, the outer surface of the cleaning roller contacting the printing roller entity, a rotation adjustment mechanism provided inside the cleaning tank, a circulating spray cleaning mechanism provided on the outer surface of the cleaning tank, a filter screen provided at the bottom of the cleaning tank, the rotation adjustment mechanism comprising a first U-shaped plate, a block, a second U-shaped plate, and a waterproof shell, a second servo motor mounted on the inner wall of the waterproof shell, a third rotating shaft mounted on the output end of the second servo motor, a second semi-circular shell fixedly connected to the left end of the third rotating shaft, the right end of the printing roller entity being mounted inside the second semi-circular shell by a second fastening screw, a second rotating shaft rotatably connected inside the block, a first semi-circular shell fixedly connected to the right end of the second rotating shaft, and the left end of the printing roller entity being mounted inside the first semi-circular shell by a first fastening screw.

[0007] Furthermore, the first U-shaped plate is fixedly connected to the inner left wall of the cleaning tank, and a first electric push rod is installed on the inner wall of the first U-shaped plate.

[0008] Furthermore, one end of the first electric push rod is fixedly connected to the block, and a first limiting slide rod is fixedly connected to the side of the block away from the first electric push rod. The first limiting slide rod is slidably connected to the inside of the first U-shaped plate and extends to the outside of the first U-shaped plate.

[0009] Furthermore, the second U-shaped plate is fixedly connected to the inner right wall of the cleaning tank, and a second electric push rod is installed on the inner wall of the second U-shaped plate.

[0010] Furthermore, one end of the second electric push rod is fixedly connected to the waterproof shell, and a second limiting slide rod is fixedly connected to the side of the waterproof shell away from the second electric push rod.

[0011] Furthermore, the second limiting slide bar is slidably connected to the inside of the second U-shaped plate and extends to the outside of the second U-shaped plate.

[0012] Compared with existing technologies, this ink printing roller cleaning device has the following advantages:

[0013] This invention, through the coordinated operation of components such as a first servo motor, a first rotating shaft, a cleaning roller, a rotation adjustment mechanism, and a second servo motor, enables the printing roller to rotate actively during cleaning. This design effectively solves the problem of the printing roller's inability to rotate actively in existing cleaning devices, improving cleaning efficiency and effectiveness. Specifically, the first servo motor drives the cleaning roller to rotate and brush the printing roller, while the second servo motor drives the printing roller to rotate through the rotation adjustment mechanism, ensuring that all parts of its outer surface can fully contact the cleaning roller, thereby achieving comprehensive and efficient cleaning.

[0014] By incorporating a circulating spraying mechanism and a filter screen, the cleaning agent is recycled, reducing resource waste. The circulating spraying mechanism sprays the cleaning agent into the cleaning tank, and the cleaning agent flows onto the surface of the filter screen during the cleaning process. After filtration, it is reused by the circulating spraying mechanism. This design not only improves the utilization rate of the cleaning agent but also helps maintain the cleanliness of the cleaning agent, thereby further enhancing the cleaning effect. At the same time, this recycling method is in line with the current development trend of environmental protection and energy conservation. Attached Figure Description

[0031] The first rotating shaft 3 is connected to the output end of the first servo motor 2 and is rotatably connected to the inside of the cleaning tank 1 to transmit power.

[0032] The cleaning roller 4 is installed on the outer surface of the first rotating shaft 3 and achieves brushing of its outer surface through contact with the printing roller body 6.

[0033] The printing roller entity 6, i.e. the printing roller to be cleaned, has its outer surface in contact with the cleaning roller 4.

[0043] The circulating spraying mechanism 7 is located on the outer surface of the cleaning tank 1 and is used to spray cleaning agent into the cleaning tank 1.

[0044] The filter screen 8 is located at the bottom of the cleaning tank 1 and is used to filter impurities in the cleaning agent to ensure the cleanliness of the cleaning agent.

[0045] When using the cleaning device of this embodiment, the printing roller entity 6 is first fixed inside the cleaning tank 1 by the first semi-circular shell 506 and the second semi-circular shell 514. Then, the first servo motor 2 and the second servo motor 512 are started, causing the cleaning roller 4 and the printing roller entity 6 to rotate simultaneously for cleaning. During the cleaning process, cleaning agent is sprayed in through the circulating spraying mechanism 7 and filtered and recycled through the filter screen 8. When it is necessary to adjust the horizontal position of the printing roller entity 6, it can be adjusted by the first electric push rod 502 and the second electric push rod 509. After cleaning is completed, all motors and electric push rods are turned off, the fastening screws are removed, and the printing roller entity 6 can be taken out.

[0046] Working Principle: In use, firstly, place the left and right ends of the printing roller entity 6 inside the first semi-circular shell 506 and the second semi-circular shell 514 respectively. Then, use the first fastening screw 507 and the second fastening screw 515 to fix the printing roller entity 6, thus completing the installation and fixation of the printing roller entity 6. When it is necessary to clean the printing roller entity 6, start the first servo motor 2. The output end of the first servo motor 2 drives the first rotating shaft 3 to rotate. The first rotating shaft 3 drives the cleaning roller 4 mounted on its outer surface to rotate. During the rotation, the cleaning roller 4 brushes the outer surface of the printing roller entity 6, thereby removing the ink adhering to the outer surface of the printing roller entity 6. At the same time, start the second servo motor 512. The output end of the second servo motor 512 drives the third rotating shaft 513 to rotate. The third rotating shaft 513 drives the second semi-circular shell 514 fixedly connected to its left end to rotate. The second semi-circular shell 514 drives the printing roller entity 6 to rotate. During the rotation, all parts of the outer surface of the printing roller entity 6 can contact the cleaning roller 4, thereby improving the cleaning effect of the printing roller entity 6. During the cleaning process, cleaning agent is sprayed into the cleaning tank 1 through the circulating spraying mechanism 7. The cleaning agent flows to the upper surface of the filter screen 8 and is then filtered through the filter screen 8. The filtered cleaning agent is then recycled through the circulating spraying mechanism 7, thereby reducing resource waste. When it is necessary to adjust the horizontal position of the printing roller entity 6, the first electric push rod 502 and the second electric push rod 509 are activated simultaneously. The first electric push rod 502 pushes the block 503 to move along the direction of the first limiting slide rod 504, and the second electric push rod 509 pushes the waterproof shell 510 to move along the direction of the second limiting slide rod 511. During the movement of the block 503 and the waterproof shell 510, the first semi-circular shell 506 and the second semi-circular shell 514 are moved respectively. The first semi-circular shell 506 and the second semi-circular shell 514 move the printing roller entity 6, thereby achieving the adjustment of the horizontal position of the printing roller entity 6. By adjusting the horizontal position of the printing roller entity 6, it can be placed in the optimal contact state with the cleaning roller 4, thereby further improving the cleaning effect. After cleaning is complete, turn off the first servo motor 2, the second servo motor 512, the first electric push rod 502 and the second electric push rod 509, and then remove the first fastening screw 507 and the second fastening screw 515 to remove the printing roller body 6 from the inside of the cleaning device.
