Hauling speed mismatch of polyolefin plastomer extruded products (Variant: Enhanced Measures)
Sorun Belirtisi
The extrudate is uneven in thickness; when the hauling is too fast, the product becomes thinner and narrower, and when the hauling is too slow, the product becomes thicker and wider.
The mismatch between the hauling speed and the extrusion speed causes dimensional deviation of the product.
In particular, additional attention is needed on the original basis; this problem is more prominent and requires focused attention.
Neden Analizi
（1）The hauling speed setting does not match the extrusion speed
（2）The haul-off machine slips and the actual hauling speed is unstable
（3）The hauling clamping force is insufficient or too large
（4）The extrusion speed fluctuates, making the hauling difficult to synchronize
（5）The hauling control system responds slowly
（6）On the original basis, additional attention is needed: fluctuations in process parameters or changes in equipment status have aggravated this problem
Çözüm
（1）Adjust the hauling speed to match the extrusion speed, and determine the synchronous speed by the weighing method
（2）Check the hauling track or roller to ensure no slipping, and replace the clamping pad when necessary
（3）Adjust the hauling clamping force to ensure uniform clamping without damaging the product
（4）Stabilize the extrusion speed and reduce fluctuation
（5）Upgrade the hauling control system to improve response speed and accuracy
（6）And strengthen process monitoring; on the original basis, additional attention is needed to pay special attention to parameter stability
Temel Çıkarım
Hauling speed mismatch needs to be solved by precisely adjusting the hauling parameters and ensuring stable hauling.
Targeted preventive measures need to be taken in different production scenarios.
