Description

Technical Field

[0001] The utility model relates to the technical field of offset printing presses, in particular to an offset printing press ink path clutch control mechanism for preventing an ink rubber roller from idling and wearing. Background Art

[0002] An offset printing press is a type of lithographic printing press. During printing, the printed image and text are first printed from the printing plate onto a rubber cylinder, and then transferred to the paper by the rubber cylinder. Offset printing presses can be divided into sheet-fed offset printing presses and web offset printing presses according to the different paper feeding methods; they can be divided into monochrome, two-color, four-color and multi-color printing presses according to the number of printing colors completed in one paper feed; they can be divided into small offset printing presses, six-page, four-page, folio and full-sheet printing presses according to the maximum paper format they can print on. In addition, there are double-sided printing presses that can print on both sides at the same time in one paper feed.

[0003] Chinese patent publication number CN113733741 B discloses an ink path clutch mechanism of an offset printing press, which includes a positioning device, an ink roller is arranged on the upper side of the positioning device, an ink clutch mechanism is arranged on one side of the ink roller, and a follower is connected to one side of the ink clutch mechanism; the ink clutch mechanism includes a lower driving device and an upper moving device arranged on the upper end of the lower driving device, and a moving adjustment device for driving the upper moving device to move is arranged inside the lower driving device and the upper moving device. The invention controls the flow of ink in the ink path by controlling the separation of the upper moving device and the lower driving device, so that when the ink driven by the follower is not needed, the flow of ink is controlled by controlling the ink clutch mechanism, so that the ink does not enter the ink roller, the ink roller stops idling, and the friction between the ink roller and the paper is eliminated, thereby avoiding the wear caused by the friction of the ink roller and extending the service life of the ink roller.

[0004] When the device is in use, the driving device must first be used to drive the ink roller to rotate. However, the driving device, whether it is a motor or other driving components, will have slight vibrations when working, thereby driving the mounting plate to vibrate, and the vibration will cause the follower on the mounting plate to rotate slightly, resulting in the inability to completely avoid the friction between the ink roller and the paper. Utility Model Content

The motor is used to drive the driving wheel to rotate, and the driving wheel cooperates with the first synchronous wheel and the first synchronous belt to drive the driving part to rotate. When the ink rubber roller needs to work, the cylinder is started, and the telescopic end of the cylinder is used to move downward to drive the connecting plate and the mounting plate to move downward. During the downward movement of the connecting plate, the movable block and the telescopic end of the telescopic rod are driven to move, thereby driving the tooth block away from the gear. At this time, the upper rotating block at the bottom of the mounting plate cooperates with the lower rotating block at the top of the second rotating column, so that the second rotating column works. When the second rotating column is used, The second synchronous wheel and the second synchronous belt drive the first rotating column to rotate, and the ink rubber roller at the bottom of the first rotating column will also rotate. However, when the ink rubber roller does not need to rotate, the telescopic end of the cylinder drives the connecting plate and the mounting plate to move upward so that the upper rotating block is away from the lower rotating block. During the movement, the movable block and the telescopic end of the telescopic rod will also move, driving the gear to engage with the gear on the outer wall of the second rotating column, thereby limiting the second rotating column, and indirectly limiting the ink rubber roller at the bottom of the first rotating column, preventing the vibration of the motor during operation from causing the second rotating column to rotate, preventing it from idling, and avoiding friction between the ink rubber roller and paper.

[0012] Preferably, the driving member comprises a motor, and the motor is arranged at the bottom of the mounting plate through a chassis.

[0013] Preferably, the top of the lower rotating block is configured to be in an arc shape for guiding the upper rotating block.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

When the ink rubber roller needs to work, the cylinder is started, and the telescopic end of the cylinder is used to move downward to drive the connecting plate and the mounting plate to move downward. During the downward movement of the connecting plate, the movable block and the telescopic end of the telescopic rod will be driven to move, thereby driving the tooth block away from the gear.
