[0019] The following further describes the present utility model in conjunction with the embodiments shown in the accompanying drawings.

[0020] A drum cleaning device for a printing press, as Figure 1 and Figure 2 shown, includes a support frame 1, a first motor 2, a lead screw 3, a sliding frame 4, a drum 5, a second motor 6, a gear 7, a cleaning tank 8 and a cleaning component. Both lower sides of the left and right parts of the support frame 1 are connected with a first motor 2. The output shafts of the first motors 2 are both connected with a lead screw 3. The lead screws 3 are both rotatably connected to the support frame 1. The sliding frames 4 are both threadedly connected to the lead screws 3. A drum 5 is rotatably connected between the sliding frames 4. The front right side of the right sliding frame 4 is connected with a second motor 6. The output shaft of the second motor 6 is connected with a gear 7. The right part of the drum 5 is also connected with a gear 7. The gears 7 are meshed with each other. The lower part of the support frame 1 is connected with a cleaning tank 8. A cleaning component is provided on the cleaning tank 8.

[0021] As Figure 2 and Figure 3 shown, the cleaning component includes a third motor 15, a brush 16 and a flat belt 17. The front right side of the cleaning tank 8 is connected with a third motor 15.

Pulley wheels are provided on the right parts of the brushes 16. A flat belt 17 is wound around between the pulley wheels.

[0022] As Figures 1 - 4 shown, it further includes a shielding cover 9, a connecting piece 10, a water spray nozzle 11, a support block 12, a pressing frame 13, a telescopic spring 14 and a roller 18. Both the left and right sides of the upper part of the cleaning tank 8 are connected with two front and rear support blocks 12. The pressing frames 13 are both slidably connected to the support blocks 12. A shielding cover 9 is connected between the front two pressing frames 13. A shielding cover 9 is also connected between the rear two pressing frames 13. Connecting pieces 10 are connected to the outer sides of the shielding covers 9. Two front and rear water spray nozzles 11 are connected to the upper part of the cleaning tank 8. Telescopic springs 14 are connected between the pressing frames 13 and the adjacent support blocks 12. The front and rear parts of the sliding frame 4 are both rotatably connected with a roller 18. The rollers 18 are both in contact and cooperate with the adjacent pressing frames 13.

[0023] When using this device, first place the support frame 1 in the cleaning area of the roller 5 of the printing press, then start the first motor 2 to drive the screw rod 3 to rotate, so that the sliding frame 4 moves downward under the action of the thread, driving the roller 5 and the roller 18 to move downward, making the roller 18 contact and press the pressing frame 13, so that the pressing frame 13 moves outward on the support block 12, and the telescopic spring 14 is compressed and contracted, driving the shielding cover 9 to move outward. When the roller 5 and the roller 18 continue to move downward, the telescopic spring 14 resumes its original state, driving the pressing frame 13 and the shielding cover 9 to move inward and reset, so that the roller 5 is located inside the cleaning box 8 and contacts the brush 16. Then turn off the first motor 2, and then connect the cleaning water externally through the water spray nozzle 11, so that the cleaning water is sprayed onto the roller 5. At the same time, start the second motor 6 to drive the front gear 7 to rotate. The gears 7 mesh with each other to drive the roller 5 to rotate. Then start the third motor 15 to drive the front brush 16 and the pulley to rotate, so that the flat belt 17 rotates, driving the rear pulley to rotate, so that the rear brush 16 rotates. The roller 5 is cleaned by the brush 16, so that the roller 5 can be conveniently cleaned automatically without stopping the machine for disassembly and cleaning, saving manpower and time and improving work efficiency. After the cleaning is completed, turn off the third motor 15, and then reverse-start the first motor 2 to drive the screw rod 3 to rotate in the reverse direction, so that the sliding frame 4 moves upward under the action of the thread, driving the roller 5 and the roller 18 to move upward, making the roller 18 contact the pressing frame 13, so that the pressing frame 13 moves outward, and the telescopic spring 14 is compressed and contracted, driving the shielding cover 9 to move outward. When the roller 5 moves between the shielding covers 9, turn off the first motor 2, and then connect the air drying device externally through the connecting piece 10, and dry the roller 5 by air, so that the roller 5 can be dried after the cleaning is completed. The operation is simple and the work efficiency is improved. After the treatment is completed, start the first motor 2 again to drive the screw rod 3 to rotate, so that the sliding frame 4 continues to move upward under the action of the thread, driving the roller 5 to move upward and reset, so that the roller 18 does not contact the pressing frame 13, and the telescopic spring 14 resumes its original state, so that the pressing frame 13 moves back to its original position.
