Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to an inking unit of a printing machine. Background Art

[0002] A printing press is a device that uses a printing plate to transfer ink or other colorants to a substrate, and is an important part of the printing process. A printing press is usually composed of a transmission unit, a printing unit, an inking unit, a wetting unit, a paper feeding unit, a positioning unit, a paper transfer unit, and a paper collection unit. Different types of printing presses may have different structures and functions, but their basic principles are similar.

[0003] The existing inking unit includes a wall panel, an adjustment seat slidably arranged on the wall panel, an ink roller and an anilox roller arranged on the adjustment seat, a driving cylinder for driving the adjustment seat to move, and an ink basin arranged on one side of the ink roller. Since the adjustment stability of the driving cylinder is poor in accuracy, it cannot be well positioned to maintain the position of the adjustment seat, which ultimately affects the adjustment accuracy and processing error. Since the ink roller and the anilox roller will generate a certain amount of vibration during operation, and the sliding matching structure between the adjustment seat and the wall panel will generate a certain amount of assembly tolerance, the formation of this assembly tolerance will further increase the vibration amplitude generated by the movement of the ink roller and the anilox roller, which to a certain extent affects the stability of the operation of the equipment and the processing accuracy.

[0011] It is further configured that: the axis of the locking rod and the movement direction of the sliding structure are perpendicular to each other in the vertical direction.

[0012] By adopting the above technical solution, this method enables the driving force to cooperate with gravity to achieve locking of the sliding structure, thereby achieving a more stable locking purpose and improving structural reliability.

[0013] It is further configured as follows: the driving structure includes a rotating arm hinged to the adjustment seat through a rotating shaft, one end of the locking rod close to the driving member is hinged to a position of the rotating arm away from the rotating shaft, and the driving member drives the rotating arm to rotate.

[0014] By adopting the above technical solution, the lever arm length is increased through the rotating arm structure to reduce the force on the driving member, thereby extending the service life of the driving member.

[0015] It is further configured as follows: it includes a connecting plate fixedly arranged on the wall panel, the driving cylinder is respectively fixedly connected to the adjusting seat and the connecting plate, the locking piece is a locking bolt threadedly connected to the cylinder body of the driving cylinder and one end of the locking bolt abuts against the connecting plate, and the axis of the locking bolt is parallel to the driving direction of the driving cylinder.

[0016] By adopting the above technical solution, after the driving cylinder drives the adjustment seat to the desired position, the locking bolt is rotated to make one end of it press against the connecting plate, so that when the driving cylinder fixes the adjustment seat, it only needs to supply air to one side of the cylinder to cooperate with the locking bolt to achieve a more stable locking purpose of the original structure.

[0017] It is further configured as follows: an ink basin is provided below the ink lifting roller, and a driving component for driving the ink basin to rise and fall is connected to the ink basin.

[0018] By adopting the above technical solution, the driving component drives the ink basin to move up and down, which is convenient for adjustment and also facilitates the ink filling operation of the ink basin.

[0019] It is further configured that: the driving component includes a rack slidably arranged on the wall panel and rising and falling with the ink basin, a gear rotatably arranged on the wall panel and meshing with the rack, and a control structure for controlling the rotation of the gear.

[0020] By adopting the above technical solution, the control structure drives the gear to rotate to cooperate with the rack to complete the lifting function of the ink basin.

[0021] It is further configured as follows: the control structure includes a control rod rotating with the gear, a material blocking rod connected to the control rod, and a limit block arranged on the wall panel and resisting the material blocking rod, the material blocking rod resists the limit block to support the ink basin in an inking state, and the material blocking rod is rotatably connected to the control rod to separate or resist the material blocking rod and the limit block.

[0022] By adopting the above technical solution, the stop rod is against the limit block to bear the weight from the ink basin, so as to support the ink basin and put it in an inking state; then, by rotating the stop rod, the coordination between the stop rod and the limit block can be released to control the lifting and lowering operation of the ink basin.

[0023] In summary, the utility model has the following beneficial effects: the utility model has precise adjustment, stable operation and high processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
