Description

Technical Field

[0001] The utility model relates to an offset printing machine, in particular to a rubber cloth tensioning mechanism and a rubber roller assembly thereof. Background Art

[0002] The State Intellectual Property Office of the People's Republic of China has published a utility model patent entitled: A color registration and plate correction device for curved offset printing presses, with an authorization announcement number of CN2433083Y and an authorization announcement date of June 6, 2001. Specifically, the invention discloses that a power system drives the device to rotate at a uniform speed through a transmission shaft A (1), and a rubber drum wheel (2) and a plate loading drum wheel (7) connected to the transmission shaft A (1) and a transmission shaft B (3) respectively rotate at a uniform speed along the shaft. When the layout needs to be adjusted, the nut B (5) can be loosened and the bolt B (4) can be screwed to apply an axial force to the transmission shaft B (3), and the flat gear (6) and the plate loading drum wheel (7) connected to the transmission shaft B (3) rotate and move axially along the transmission shaft B (3), so that the plate loading drum wheel (7) and the rubber drum wheel (2) are relatively displaced in the lateral direction accordingly, so as to achieve lateral adjustment of the layout; after the adjustment is completed, the nut B (5) can be tightened to fix the transmission shaft B (3) in the axial direction. By loosening the nut C (10) and tightening the bolt C (11), an axial force is applied to the transmission shaft C (8), and the bevel gear (9) connected to the transmission shaft C (8) rotates with the transmission shaft C (8) while displacing in the axial direction. The bevel gear (9) and the transmission shaft A are correspondingly displaced relatively. In the process of relative displacement, the bevel gear (9) generates an advance or lag displacement difference, which makes the rotation of the transmission shaft C (8) advance or lag relative to the rotation of the transmission shaft A (1). The advance or lag is converted from the bevel gear transmission to the flat gear transmission through the tooth-changing gear (13) on the transmission shaft D (12) and transmitted to the transmission shaft B (3), so that the rotation of the plate loading drum wheel (7) is advanced or delayed relative to the rotation of the rubber drum wheel (2), thereby realizing the longitudinal adjustment of the plate surface; after the adjustment is completed, the nut C (10) is tightened to fix the axial position of the transmission shaft C (8). Since the device only drives and adjusts one end of the roller and does not adjust the other end of the roller, when the plate roller and the rubber roller are long, when one end of the roller is adjusted into place, the other end of the roller is not adjusted into place, and when the other end of the roller is adjusted into place, one end of the roller has been over-adjusted, and even printing skew may occur.

[0003] The State Intellectual Property Office of the People's Republic of China published a utility model patent on, entitled: Components for offset printing press, corresponding cylinders, rubber cloth unit and offset printing press, with publication number: CN1307052C, and publication date: June 24, 2022, which specifically discloses a component (1) for an offset printing press, which includes: a rubber cloth unit (3), which includes a rubber cloth (64) and a rubber cloth support plate (62), the front edge (66) and the rear edge (72) of the support plate (62) are respectively The support plate (62) is bent near the front curved portion (70) and the rear curved portion (76), and the rear edge (72) of the support plate (62) extends beyond the rear edge (74) of the rubber sheet near the rear curved portion (76); and a roller (2) has a gap (14) for accommodating the front edge and the rear edge of the support plate (62), and the roller (2) includes a device (28) for fixing the rubber sheet unit (3) on the roller, and the fixing device (28) includes at least one hook (30) for tensioning the rubber sheet unit. Since the hooks (30) are distributed at intervals along the main axis (28), the hooks (30) apply force to the rear edge (72) of the support plate (62) at intervals. When the support plate (62) is relatively soft, the tension on the middle part of the rubber sheet (64) between the two hooks (30) is insufficient, which is not conducive to uniform tensioning of the rubber sheet (64).

[0004] The State Intellectual Property Office of the People's Republic of China has published a utility model patent, entitled: An axial adjustment mechanism for a printing plate roller, with an authorization announcement number of CN217226972U and an authorization announcement date of August 19, 2022. The following technical solutions are specifically disclosed, including a mounting frame and a transmission shaft, an adjustment rod is provided on the mounting frame, a movable plate is rotatably connected to one end of the front side of the adjustment rod, and a movable rack is fixedly connected to both sides of the back side of the movable plate, an arc sleeve is provided on the movable rack, and a gear is provided on the side of the movable rack, a rotating shaft is installed on the gear, an adjustment member is provided at the bottom end of the rotating shaft, and a connecting member is movably connected to one end of the transmission shaft, and the connecting member and the adjusting member are movably connected. Since the angular change of the adjustment rod rotation and the displacement change of the axial movement of the transmission shaft cannot form a linear relationship, it is not easy to accurately adjust the axial position of the plate roller.
