In order to extend the service life of the wire drawing machine, it is recommended that in addition to daily and weekly maintenance, a thorough maintenance and overhaul should be performed once a month. The following summarizes some troubleshooting methods that are prone to occur in wire drawing machines.
1. The film has pores
Cause of issue:
(1)The raw materials have too much moisture;
(2)The extruder temperature is too high;
(3)The raw materials are impure;
(4)Too many impurities in raw materials;
(5)Just replaced the screen.
Method of exclusion:
(1)Dry again;
(2) Reduce the extruder temperature;
(3) Replace raw materials;
(4) Replace raw materials;
(5)Extend the extrusion time.
2. Film jumping knife
Cause of issue:
(1)The machine head temperature is too high;
(2)The incision is not fast or at an improper angle;
(3)The stretching and baking temperature is too high.
Method of exclusion:
(1)Improve the machine head temperature;
(2)Replace the blade or change the angle of the cutter;
(3) Improve baking temperature.
3. The wire is easy to break when stretched
Cause of issue:
(1) The stretching and baking temperature is too low;
(2) Too many impurities in raw materials;
(3) The thickness of the film surface is uneven;
(4)The speed is too fast and the wire is too thin.
Method of exclusion:
(1) Adjust the stretching and baking temperature;
(2) Replace the screen with a larger mesh number or increase the number of screens;
(3)Adjust the uniformity of the die mouth;
(4)Adjust the mechanical speed.
4. The surface of the film is not smooth
Cause of issue:
(1)The extruder temperature is too high or too low;
(2) The extrusion pressure is too small;
(3)The raw materials are impure or have too many impurities.
Method of exclusion:
(1) Adjust the temperature;
(2) Replace the screen with a larger mesh number or increase the number of screens;
(3)Replace raw materials.
