[0031] Reference Figures 1 to 3 The printing roller cleaning device of the first embodiment of the utility model includes: a frame 100, which is provided with a first driving component 110; a feeding mechanism, including a feeding roller 210, and the feeding roller 210 is rotatably arranged on the frame 100; a receiving mechanism, including a receiving roller 220, and the receiving roller 220 is rotatably arranged on the frame 100; a cleaning mechanism 300, including a second driving component and a cleaning roller 320, and the second driving component drives the cleaning roller 320 to move toward the printing roller; wherein, the first driving component 110 drives the receiving roller 220 to rotate periodically.

[0032] The printing roller cleaning device is installed in a printing machine, a cleaning cloth is installed on a feeding roller 210, and the cloth is unfolded to connect the cloth to a receiving roller 220, and the cloth passes around a cleaning roller 320. During cleaning, the cleaning roller 320 is driven toward the printing roller by a second driving component to make the cloth contact the printing roller, and the printing roller rotates. The printing roller is wiped with a cleaning cloth to clean the printing roller, thereby avoiding the need to disassemble the printing roller for cleaning. This is convenient and fast, and reduces safety risks. In addition, the receiving roller 220 is periodically driven to rotate by the first driving component 110, so that a clean cleaning cloth is replaced at intervals to wipe the printing roller, thereby improving the utilization rate of the cleaning cloth, reducing the replacement frequency of the cleaning cloth, and improving efficiency.

[0033] It is understandable that, referring to Figure 2 and Figure 3 The first driving assembly 110 includes a first cylinder 111, a transmission member and a first rotating member 115. The first rotating member 115 is coaxially arranged with the receiving roller 220. The first cylinder 111 drives the rotating member to rotate periodically through the transmission member. Through the cooperation of the transmission member, the first cylinder 111 drives the first rotating member 115 to rotate periodically, thereby improving the utilization rate of the cloth.

[0034] It is understandable that, referring to Figure 1 and Figure 2The transmission member includes a second rotating member 112, a connecting rod 113 and a lever 114. The first cylinder 111 drives the second rotating member 112 to rotate. The lever 114 is rotatably arranged on the frame 100. One end of the connecting rod 113 is hinged to the second rotating member 112, and the other end of the connecting rod 113 is hinged to the lever 114. The other end of the lever 114 drives the first rotating member 115 to move. The first cylinder 111 drives the second rotating member 112, and the second rotating member 112 drives the connecting rod 113 to move. The connecting rod 113 drives the lever 114 to rotate. The end of the lever 114 shifts the first rotating member 115, drives the receiving roller 220 to rotate, pulls the cleaning cloth, and releases the cleaning cloth from the feeding roller 210. The cleaning cloth moves, removes the dirty cleaning cloth from the cleaning roller 320, and covers the cleaning roller 320 with a clean cleaning cloth, so as to realize automatic replacement of the cleaning cloth, which is convenient and fast, and improves efficiency.

[0035] It is understandable that, referring to Figure 2 and Figure 3 , a first tooth portion 116 is provided at one end of the lever 114, and a second tooth portion 117 is provided at the first rotating member 115. The connecting rod 113 drives the lever 114 to rotate, so that the first tooth portion 116 shifts the second tooth portion 117. The lever 114 rotates, so that the first tooth portion 116 meshes with the second tooth portion 117, and then the lever 114 continues to rotate, so that the first tooth portion 116 drives the second tooth portion 117 to rotate, thereby realizing the rotation of the first rotating member 115. When the first cylinder 111 is reset, the lever 114 is driven to rotate in the opposite direction, and the first tooth portion 116 is separated from the second tooth portion 117. When the set time is reached, the first cylinder 111 is started again, and the lever 114 continues to drive the first rotating member 115 to rotate in the same direction through the first tooth portion 116, so as to realize the periodic movement of the receiving roller 220 and improve the utilization rate of the cleaning cloth. It should be noted that the periodic start-up of the first cylinder 111 can be achieved through the cooperation of PLC and solenoid valve. This technology is existing technology and will not be described in detail here.

[0036] It is understandable that, referring to Figure 4 and Figure 6 The second driving assembly includes a mounting seat 310, a second cylinder 312 and a first movable block 313. The mounting seat 310 is arranged on the frame 100, and the second cylinder 312 is arranged on the mounting seat 310. The second cylinder 312 drives the first movable block 313 to move, and the first movable block 313 abuts against the cleaning roller 320. The second cylinder 312 drives the first movable block 313, and the first movable block 313 drives the cleaning roller 320 to extend. The cleaning roller 320 drives the cleaning cloth to abut against the printing roller to clean the ink on the printing roller and improve the cleaning effect. After the cleaning is completed, the second cylinder 312 is reset, so that the cleaning roller 320 is reset, and the cleaning cloth leaves the printing roller.

[0037] Specifically, refer to Figure 1 and Figure 2 The cleaning roller 320 includes a connecting member 322 and a cleaning head 321. The cleaning head 321 is clamped on the connecting member 322. The connecting member 322 is movably arranged on the mounting seat 310. The first movable block 313 drives the connecting member 322 to move. By clamping the cleaning head 321 on the connecting member 322, it is convenient to disassemble and replace the cleaning head 321, thereby reducing the difficulty of maintenance.

[0038] It is also understandable that, with reference to Figure 4 and Figure 6 The connecting member 322 is provided with a positioning hole 324, and the first movable block 313 is inserted into the positioning hole 324. The first movable block 313 abuts against the side wall of the positioning hole 324. The first movable block 313 is plugged into and matched with the positioning hole 324, and the friction between the first movable block 313 and the side wall of the positioning hole 324 is utilized to realize that the first movable block 313 drives the connecting member 322 to move.

[0039] It is understandable that, referring to Figure 4 and Figure 5 , the connecting member 322 is provided with a stabilizing assembly, and the stabilizing assembly is used to stabilize the cleaning head 321 on the connecting member 322. Specifically, the stabilizing assembly includes a guide rod 326, a spring 327 and a second movable block 313, the spring 327 is sleeved on the guide rod 326, the second movable block 313 is arranged on the guide rod 326, one end of the spring 327 abuts against the second movable block 313, and the other end of the spring 327 abuts against the connecting member 322, and the spring 327 drives the second movable block 313 to pass through the connecting member 322 and abut against the cleaning head 321. The second movable block 313 is driven to abut against the cleaning head 321 by the spring 327, so that the cleaning head 321 is close to the connecting member 322, thereby improving the clamping effect between the cleaning head 321 and the connecting member 322. The guide rod 326 can prevent the spring 327 from bending and prevent the spring 327 from failing.

[0040] It is understandable that, referring to Figure 3 The cleaning head 321 is provided with a limiting groove 323, and the connecting member 322 is provided with a limiting block 311, which extends into the limiting groove 323. When the cleaning roller 320 is extended, the limiting block 311 abuts against the side wall at one end of the limiting groove 323, and when the cleaning roller 320 is reset, the limiting block 311 abuts against the side wall at the other end of the limiting groove 323, thereby limiting the movable stroke of the connecting member 322 and preventing the cleaning roller 320 from falling off the mounting seat 310.

[0041] It is understandable that, referring to Figure 3 An arc-shaped portion is provided on the side of the cleaning head 321 facing the printing roller, which increases the contact area between the cleaning head 321 and the cleaning cloth, makes the replacement of the cleaning cloth smooth, and reduces the friction force on the cleaning cloth, avoiding the cleaning cloth being torn and damaged due to excessive friction, thereby improving stability, reducing the frequency of replacing a new cleaning cloth, and reducing labor intensity.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
