Description

TECHNICAL FIELD

[0001] The utility model relates to a rubber blanket cleaning device. BACKGROUND

[0002] Rubber blanket, namely the package of the transfer cylinder on the offset press, is a component of the blanket, which is a composite product composed of rubber coating and base material (such as fabric). In indirect lithographic printing, it is used to transfer ink from the printing plate to the printing material. However, during continuous printing, a large number of impurities and particles may adhere to the rubber blanket, and excessive ink on the surface of the rubber blanket may also affect the printing effect. Therefore, the rubber blanket needs to be cleaned after a certain period of use. However, the existing cleaning methods for rubber blankets are mostly manual or with the help of some cleaning tools. However, the cleaning process is relatively complicated, and the cleaning agent used in the process contains a large amount of volatile substances, which may pose a certain risk to the health of the workers.

[0003] During the cleaning process of the rubber blanket, the ink will gradually separate from the rubber blanket with the cleaning liquid, keeping the surface of the rubber blanket smooth. The clean rubber blanket can more evenly transfer ink during the printing process, improving the printing quality.

[0004] The utility model with the application number CN202321710967. X relates to the technical field of cleaning devices and discloses a rubber blanket cleaning device, which includes a shell. The bottom of the shell is provided with a roller, and the front of the shell is provided with a driving motor. A cleaning mechanism is arranged inside the shell. The cleaning mechanism includes a rotating shaft, which is fixedly connected with the output shaft of the driving motor. The utility model sets the driving motor, the driving wheel, the movable wheel, the cleaning cloth, and the movable plate. The water source inside the connecting shell can fall through the movable plate and be absorbed by the cleaning cloth. When the driving motor operates, the driving wheel will rotate through the rotating shaft, so that the cleaning cloth can move through the cooperation between the driving wheel and the movable wheel. The cleaning cloth can clean the outer surface of the rubber blanket and change the contact surface with the rubber blanket, so that the ink will not be smeared back onto the rubber blanket, thereby cleaning the rubber blanket.

[0005] The above-mentioned patent cleans the rubber blanket by changing the contact surface of the rubber blanket through the movement of the cleaning cloth, preventing the ink from returning to the rubber blanket. However, during the cleaning process of the rubber blanket, the position of the rubber blanket will gradually deviate with the rotation of the rotating roller, causing uneven cleaning of the ink on the surface of the rubber blanket. Secondary cleaning of one place will greatly reduce the work efficiency.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. UTILITY MODEL CONTENT
