Description

Technical Field

[0001] This utility model relates to the field of printing roller cleaning technology, and in particular to a printing roller cleaning device for text printing. Background Technology

[0002] Printing press rollers are the core components of printing machinery. Their surface finish and geometric precision have a significant impact on the quality of printed materials. Therefore, cleaning printing press rollers plays an important role in ensuring printing quality and efficiency, maintaining equipment performance, and extending equipment life.

[0003] A search revealed Chinese Patent Publication No. CN214137899U, which discloses a printing roller cleaning device for text printing. The device includes a base box with a partition fixedly connected to its inner wall, dividing the inner wall into a clean water chamber and an ink chamber. Two support frames are fixedly connected to the upper end of the base box, and a cleaning tank is fixedly connected to the opposing ends of the support frames. A motor is fixedly connected to the side wall of the cleaning tank via a fixed plate, and a drive shaft is fixedly connected to the output end of the motor. A drive gear is fixedly connected to the side wall of the drive shaft. A driven shaft is movably connected to the upper end of the fixed plate via a fixed block, and a driven gear is fixedly connected to the side wall of the driven shaft. A first water pump and a second water pump are fixedly connected to the upper end of the base box. This device uses recycled ink and clean water to clean the printing roller in stages, effectively removing stains and facilitating its continued use.

[0004] While the aforementioned technologies achieve the cleaning of printing rollers, they involve fixing the printing rollers to be cleaned onto a fixed or driven shaft, then flipping the limiting shell downwards and engaging the limiting block onto the printing rollers. This process can restrict the size of the print rollers that can be cleaned and makes the fixing operation inconvenient, thus affecting the cleaning efficiency of the printing rollers and making them less convenient to use. Therefore, a text printing roller cleaning device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a printing roller cleaning device for text printing, which aims to improve the existing technology where the printing roller to be cleaned is fixed on the fixed drive shaft or driven shaft, and then the limiting shell is flipped down and the limiting block is attached to the printing roller. This easily leads to the limitation of the size of the cleaningable printing roller and the inconvenience of fixing operation, thus affecting the cleaning efficiency of the printing roller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for printing rollers in text printing, comprising a cleaning tank, an mounting base fixedly connected to the inner wall of the cleaning tank, a filter plate provided on the top of the mounting base, a cleaning liquid tank fixedly connected to the back of the cleaning tank, an inlet pipe fixedly connected to the rear edge of the top of the cleaning liquid tank, a return pump fixedly connected between the right side of the inlet pipe and the back of the cleaning tank, a cover fixedly connected to the top outer edge of the top of the cleaning tank, a sprayer fixedly connected to the top of the inner wall of the cover, a supply pump fixedly connected between the top of the sprayer and the top of the cleaning liquid tank, a mounting frame fixedly connected to the back of the sprayer, a telescopic cleaning brush fixedly connected to the front of the mounting frame, a motor fixedly connected to the right side of the cover, and adjustment and fixing components provided on the left side of the inner wall of the cover and the left output end of the motor.

[0007] As a further description of the above technical solution:

[0008] There are two adjustment and fixing components. Each adjustment and fixing component includes two rotating disks. The outer periphery of the two rotating disks is respectively engaged with the inner wall of the machine cover on both sides. One of the rotating disks is fixedly connected to the output end of the motor. An electric telescopic rod is fixedly connected to the inner side of the two rotating disks. The telescopic end of the electric telescopic rod is fixedly connected to a printing roller clamp.

[0009] As a further description of the above technical solution:

[0010] The printing roller clamp is provided with a slot on the inner side, and an adjusting screw is threadedly connected to the top of the printing roller clamp. The bottom end of the adjusting screw extends into the inside of the slot and is rotatably connected to a pressure seat.

[0011] As a further description of the above technical solution:

[0012] One end of the return pump is connected to the back of the cleaning tank through a suction pipe, and the other end of the return pump is connected to the right side of the inlet pipe through a return pipe.

[0013] As a further description of the above technical solution:

[0014] Protective doors are hinged to both sides of the front of the hood.

[0015] As a further description of the above technical solution:

[0016] The bottom of the sprayer is provided with multiple high-pressure spray nozzles evenly spaced.

[0017] As a further description of the above technical solution:

[0018] One end of the liquid supply pump is connected to the top of the cleaning liquid tank through a liquid extraction pipe, and the other end of the liquid supply pump is connected to the top of the sprayer through a liquid supply pipe.

[0019] As a further description of the above technical solution:

[0020] The telescopic cleaning brush includes an electrically controlled telescopic rod and a cleaning brush.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a sprayer, a telescopic cleaning brush, and an adjusting and fixing assembly are used. An electric telescopic rod combined with a printing roller clamp is adjusted and fixed according to the actual size of the printing roller. The rotating disk on one side is fixedly connected to the output end of the motor to drive the fixed printing roller to rotate. Multiple high-pressure spray nozzles at the bottom of the sprayer, combined with the telescopic cleaning brush of the electric telescopic rod and the cleaning brush, can be extended and adjusted to fit the outer wall of the printing roller for high-pressure flushing and cleaning. This makes it suitable for cleaning printing rollers of different sizes.
