Other problems of pouch-making length deviation
4. Preset film length
The difference between the preset film feeding length (when adjusting the white bag) and the actual bag size is too large. Not covering the cursor in the scanning area can directly lead to inaccurate tracking, so it should be as accurate as possible in the actual setting.
5. Influence of plastic laminated film pouch-making processing speed on size deviation of pouch-making length
When the pouch-making process speed is faster, the deviation related to the pouch-making length control increases obviously. The main reason is: under the inertia action of high speed operation, the action of cutting knife and feeding roller is affected to a certain extent. Because the heat sealing knife, cutting knife and feeding roll action is affected by different degrees, which leads to the increase of the bottom margin and other deviations. For the pouch making machine with higher manufacturing accuracy, it is possible to form quantitative systematic error, which can be basically stable after adjustment.
6. The effect of inertia
In addition, the film speed up or down too fast, due to the existence of inertia, it is easy to cause the film error is large. Therefore, the adjustment of pouch-making speed should be carried out slowly.
