Description

Technical Field

[0001] This application relates to the field of printing press plate cylinder cleaning technology, and in particular to a printing press plate cylinder cleaning device. Background Art

[0002] During intaglio printing, the entire surface of the printing plate cylinder is inked. The ink on the blank part of the plate surface is scraped off with a doctor blade, leaving the ink on the graphic part. Then, the paper is passed through, and the impression cylinder presses on the back of the paper, so that the ink in the recessed part is directly transferred to the paper surface. Finally, the printed products are stacked or rewound by the paper receiving part.

[0003] Currently, when cleaning the printing press plate cylinder, it is often necessary to remove the printing press plate cylinder from the printing press for cleaning, and then install the printing press plate cylinder on the printing press after cleaning. Therefore, when cleaning the printing press plate cylinder, the disassembly and assembly of the printing press plate cylinder are relatively cumbersome. Utility Model Content

[0004] In order to improve the problem of relatively cumbersome disassembly and assembly of the printing press plate cylinder when cleaning it, this application provides a printing press plate cylinder cleaning device.

[0005] A printing press plate cylinder cleaning device provided by this application adopts the following technical solution:

[0006] A printing press plate cylinder cleaning device includes a cleaning tank. An installation frame is arranged in the cleaning tank. An installation rod is fixed between the opposite inner side surfaces of the installation frame. A plurality of bristles are fixed on the outer peripheral surface of the installation rod. A fixing member for fixing the cleaning tank on the printing press is arranged on the cleaning tank.

[0007] By adopting the above technical solution, before cleaning the printing press plate cylinder, place the cleaning tank directly below the printing plate, and then fix the cleaning tank on the printing press through the fixing member, so that the bristles are in contact with the printing press plate cylinder. Then start the printing press to make the printing press plate cylinder rotate, so that the bristles clean the printing press plate cylinder, reducing the disassembly and assembly of the printing press plate cylinder.

[0008] Preferably, the fixing member includes support shafts fixed on both side surfaces of the cleaning tank. A driving tube is sleeved at one end of the support shaft away from the cleaning tank. A top block is rotatably installed at one end of the driving tube away from the cleaning tank.

[0009] By adopting the above technical solution, when the cleaning tank is placed directly below the printing plate, by rotating the driving tube, the driving tube drives the top block to move in a direction away from the cleaning tank, so that the top block presses tightly against the frame of the printing press, thereby fixing the cleaning tank directly below the printing plate.

[0010] Preferably, a cylinder is fixed on the inner side surface of the cleaning tank, and the end surface of the piston rod of the cylinder is fixedly connected to the side surface of the installation frame.

[0011] By adopting the above technical solution, when the cylinder is started, the piston rod of the cylinder drives the mounting bracket to move towards the printing press plate cylinder, so that the mounting bracket drives the brush bristles to move towards the printing press plate cylinder, thereby facilitating the abutment of the brush bristles against the outer peripheral surface of the printing press plate cylinder.

[0012] Preferably, a water pump is provided on the side surface of the cleaning tank. An inlet pipe is provided at the water inlet of the water pump, and an outlet pipe is provided at the water outlet of the water pump. A cavity is formed inside the mounting rod, and a plurality of water spraying holes are formed on the inner peripheral surface of the cavity. The end of the inlet pipe away from the water pump passes through the end face of the mounting rod and is inserted into the cavity.

[0013] By adopting the above technical solution, when the printing press plate cylinder rotates and the brush bristles clean the printing press plate cylinder, the water pump is started. The water pump pumps water into the water pump through the inlet pipe, then conveys the water into the cavity through the outlet pipe, and then sprays the water onto the printing press plate cylinder through the water spraying holes, thereby facilitating the flushing of the stains on the plate cylinder by the water when the brush bristles clean the printing press plate cylinder.

[0014] Preferably, an air outlet pipe is provided in the cleaning tank. The air outlet of the air outlet pipe is arranged towards the mounting rod, and a fan is arranged inside the air outlet pipe.

[0015] By adopting the above technical solution, after the plate cylinder is cleaned, the fan is started. The fan blows air towards the plate cylinder through the air outlet pipe, thereby facilitating the drying of the cleaned plate cylinder.

[0016] Preferably, a heating wire is arranged inside the air outlet pipe, and the heating wire is located on the side of the fan close to the mounting rod.

[0017] By adopting the above technical solution, when the fan is started, the fan blows air towards the heating wire, so that the air blown out by the air outlet pipe is hot air, thereby facilitating the acceleration of the drying of the plate cylinder.

[0018] Preferably, a sliding groove is formed on the inner wall of the cleaning tank. A slider is fixed at the end of the air outlet pipe away from the mounting rod, and the slider is slidably arranged in the sliding groove. A driving member for driving the slider to move along the length direction of the cleaning tank is arranged in the sliding groove.

[0019] By adopting the above technical solution, when the driving member is started, the driving member drives the slider to move along the length direction of the cleaning tank, so that the slider drives the air outlet pipe to move along the length direction of the cleaning tank, thereby facilitating the improvement of the drying efficiency of the plate cylinder.

[0020] Preferably, the driving member includes a reciprocating lead screw rotatably mounted between the opposite inner sides of the chute. The reciprocating lead screw passes through the slider and is threadedly connected to the slider. A motor is provided in the chute, and the output shaft of the motor is fixedly connected to one end of the reciprocating lead screw.

[0021] By adopting the above technical solution, when the motor is started, the output shaft of the motor drives the reciprocating lead screw to rotate, and the reciprocating lead screw drives the slider to move axially back and forth along the reciprocating lead screw, so that the slider drives the air outlet pipe to move along the length direction of the cleaning tank.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Before cleaning the printing press plate cylinder, place the cleaning tank directly below the printing plate, and then fix the cleaning tank to the printing press through the fixing member, so that the brush bristles are in contact with the printing press plate cylinder. Then start the printing press to make the printing press plate cylinder rotate, so that the brush bristles clean the printing press plate cylinder, reducing the disassembly and assembly of the printing press plate cylinder.

[0024] 2. When the cleaning tank is placed directly below the printing plate, by rotating the driving tube, the driving tube drives the top block to move away from the cleaning tank, so that the top block presses tightly against the frame of the printing press, thereby fixing the cleaning tank directly below the printing plate.

[0025] 3. When the printing press plate cylinder rotates and the brush bristles clean the printing press plate cylinder, start the water pump. The water pump pumps water into the water pump through the water inlet pipe, then transports the water to the cavity through the water outlet pipe, and then sprays the water onto the printing press plate cylinder through the spray holes, so that when the brush bristles clean the printing press plate cylinder, the water flushes away the stains on the plate cylinder.
