(2)电眼跟踪不准，跟踪不准的原因有以下几点：

(2)Eye mark does work properly.may caused by reason below:

A:电眼问题：光电眼调整方法及工作状态选择不当。

A Eye mark was unproperly setted

B光标印制或间距问题

B Marks on film are wrongly printed(including printing differences between marks and marks,or the the mark is too small to be tracked)

C走膜阻力：当走膜阻力过大（受压膜尺条压紧程度、复合薄膜摩擦系数的影响）时，可能会引起走膜不到位或光标变形，进而影响扫描效果，导致制袋长度的相关偏差。

C The friction of film is too big when infeeding sothat it cause the over tension of the film(drag the film)

D预调的送膜长度：预调的送膜长度（按调整白袋时）与实际制袋尺寸误差太大，扫描区没有覆盖光标时，可直接导致跟踪不准。

D The setting length is much more bigger(smaller) than the actual distance between marks and marks

(3)塑料复合膜制袋加工速度的影响当制袋加工速度较快时，与长度控制有关的偏差就明显增加，其主要原因是机械控制在高速惯性的作用下，切刀和送料辊的动作受到了一定的影响。由于热封刀、切刀和送料辊的动作受到的影响程度是不同的，也就导致了底边余量等偏差的增加。但是，对于制造精度较高的制袋机来说，形成定量系统误差是可能的，经调整后可以实现基本稳定。另外，走膜升速、降速的过程太快时，由于惯性的存在，也易造成走膜误差偏大。(3)Plastic composite film bag making the influence of processing speed when making bags processing speed, and the length of the deviation is significantly related control increasing, the main reason is the mechanical control in high speed under the action of inertia, cutting knife and feed roller action are affected. Since heat sealing, cutting knife knife and feed roller of the move was the influence degree is different, have led to such as the increase of cushion bottom deviation. But, for the manufacturing precision of bag making machine, it is possible to form quantitative system error, and the adjustment can realize basic stability. In addition, go film acc, slow down the process too fast, due to the existence of inertia, also easy to cause go film error too large.

(4)操作因素

(4)operation error:(as following)

A走膜橡胶辊压力气缸的压力设定不足。

A insufficient air pressure for rubbler roller

B各段张力设定不当。特别是对于较薄的复合薄膜，张力过大时可能引起间距的变化，应小心进行张力的设定。
