Problems solved by technology
Most of the skew adjustments when the machine is stopped are manually operated by the operator. The alignment time is long and the positioning accuracy is not high. The production efficiency of this method is low; the skew adjustment of non-stop printed products is sometimes adjusted by adjusting the angle of the printing plate clamp. skew, this method is easy to cause dot ghosting and produce waste products, the waste rate is relatively high
Some use the eccentric sleeve on one side of the printing plate cylinder to tilt the axis of the printing plate cylinder to achieve the purpose of adjusting the skew of the printing plate. The change of the printed product caused by the pressure change between the rollers is difficult to meet the requirements of high-grade printed products

Embodiment Construction
[0017] Such as figure 1 with figure 2 The non-stop printing skew adjustment mechanism of the multi-color printing machine shown includes the operation surface wallboard 1 and the first transfer cylinder 4 located between the impression cylinder 2 and the second transmission cylinder 3, the cylinder shaft 5 of the first transmission cylinder 4 and the printing The machine wall board is connected, and the angle bisector of the angle formed by the connecting line between the embossing cylinder 2 and the first passing cylinder 4 and the connecting center line between the first passing cylinder 4 and the second passing cylinder 3 is defined as the Y axis 6 . The connecting end of the roller shaft 5 of the first transmission roller 4 and the operation surface wallboard 1 is equipped with a movable sleeve 7, and the roller shaft 5 is mounted on the movable sleeve 7 through a bearing. The operation surface wallboard 1 is provided with a through hole 8, and the movable sleeve 7 is in...

The invention discloses a non-stop printed product skew adjustment mechanism for a multi-color printing machine, which includes an operation surface wallboard, an impression cylinder, a second transmission cylinder and a first transmission cylinder, a connection line between the impression cylinder and the first transmission cylinder and a first transmission cylinder. The angle bisector of the angle formed by the connecting line between the roller and the second roller is the "Y" axis. The connecting end of the roller shaft of the first roller and the wall panel of the operation surface is equipped with a movable sleeve, and the wall panel of the operation surface is provided with a through hole. , the movable sleeve is installed in the through hole and can move in the Y-axis. The guide device for moving the movable sleeve along the Y-axis is fixed on the wall panel of the operation surface. A sliding drive mechanism is arranged above the movable sleeve to drive the movable sleeve to move along the Y-axis. An elastic supporting device is arranged under the movable sleeve. The adjustment of the skew of printed products by this mechanism is realized by changing the size of the gripper on one side of the first transmission cylinder, which will not change the pressure between the ink roller, printing cylinder and rubber cylinder, and can reduce the reject rate. The adjustment is fast and reliable without stopping the machine, and the operation is simple.
Description
technical field [0001] The invention relates to a non-stop printed product skew adjustment mechanism for a multi-color printing machine. Background technique [0002] At present, there are two ways to adjust the skew of multi-color printing machines: one is to adjust the skew when the machine is stopped, and the other is to adjust the skew of printed products without stopping the machine. Most of the skew adjustments when the machine is stopped are manually operated by the operator. The alignment time is long and the positioning accuracy is not high. The production efficiency of this method is low; the skew adjustment of non-stop printed products is sometimes adjusted by adjusting the angle of the printing plate clamp. This method is easy to cause dot ghosting and produce waste products, and the waste product rate is relatively high. Some use the eccentric sleeve on one side of the printing plate cylinder to tilt the axis of the printing plate cylinder to achieve the purpos...
