山东包装印刷时产生续纸误差的原因有哪些?

(1)规矩定位方面的原因。

(1) the reasons for the positioning of the rules.

1.前规挡纸舌太低或太高,导致前规边纸张卷曲或走不到位,出现周向套印误差。

1., the front gauge paper is too low or too high, leading to the front edge of the paper curled or not in place, there is a circumferential overprinter error.

2.前规定位板因长期磨损留下线形凹槽。

2. the front alignment plate leaves a linear recess due to long wear.

3.两前规不在一条直线上,叼纸 幅度两头悬殊,纸张叼口边和前规接触时不是线接触而是点接触,纸张的接触点在冲击力的作用下发生变形,变形量不一致导致套印不准。

3. two years ago is not in a straight line, the gripper margin two gap, paper in its mouth edge and the front gauge contact line contact but not point contact, the contact point of the paper deformation in the impact force, the deformation caused by inconsistent misregister.

4.侧规的拉力太大或太小,侧规挡纸舌太高或太低,导致侧规边纸张卷曲或走不到位,出现轴向套印误差。

The tension of 4. side gauge is too big or too small, and the side gauge paper is too high or too low, which causes the side gauge edge paper to curl or not to go in place, and the axial overprinting error occurs.

5.毛刷轮的压力大小不大不当或位置调节不当。

5. brush wheel pressure is not large, improper or improper position adjustment.

6.侧规工作时间不当。工作时间过早,纸张还没有到达前规就会被侧规压住而走不到位。侧规拉纸轮或球的落下时刻应该保证是在纸张到达前规后。工作时间太晚,摆动递纸牙叼住纸张向前运动,拉纸轮仍压着纸边,把纸张从摆动递纸牙中拉出一些。侧规拉纸轮或球的抬起时刻应该在递纸牙叼紧纸张、递纸牙开闭牙滚子离开凸轮的同时。

6. side gauge work time is improper. Work time is too early, the paper has not arrived, the gauge will be side gauge pressure and go nowhere. The falling time of the side drawing paper wheel or ball shall be guaranteed before the paper reaches the front gauge. Working too late, swinging the gripper, holding the paper and moving forward, the paper wheel still presses the edge of the paper and pulls the paper out of the swinging paper. The lifting time of the side gauge paper wheel or ball shall be at the same time that the gripper holds the paper, the gripper opens, and the tooth roller leaves the cam.

(2)滚筒叼牙、摆动递纸牙都要求叼力均匀、稳定。由于所印纸张时厚时薄,对叼牙弹性的损伤、表面的磨损影响较大,造成局部叼力太小会出现纸张脱出,导致套印不准。

(2) the rollers hold the teeth and swing the paper, all of them require uniform and stable grip. Because the paper is thick and thin, it has a great influence on the elasticity of the tooth and the surface of the tooth. It will cause the paper to appear out of place and cause the overprinter to be inaccurate.

(3)交接方面的原因。纸张从一个机构到下一个机构的交接过程中,如果交接时间或交接位置调节不当,会导致套印不准,甚至撕破纸张。

(3) the reasons for the handover. The transfer of paper from one institution to the next, if the handover time or position is improperly adjusted, will lead to overprinter or even tear paper.

(4)机械振动方面的原因。机械振动一般是因为机械自身的质量问题,或机械经长时间使用磨损所造成的。一般有滚筒和递纸牙的轴向串动和三滚筒的传动齿轮在长期使用过程中磨损,造成滚筒在滚压过程中出现跳动等现象。

(4) the cause of mechanical vibration. Mechanical vibration is usually due to mechanical quality problems or mechanical wear and tear caused by prolonged wear and tear. In general, there are roller and paper delivery of the axial series of teeth and three drum drive gear in the long-term use of the process of wear and tear, resulting in roller rolling in the process of beating and so on.
