Common faults and solutions of film blowing machine

date:2021-05-24 00:00 source:http://m.jingduwang.cn click:

The maintenance of the machine is very important. Long term full load operation will cause great loss to the fuselage. If the fuselage is not cleaned and maintained in time, it is easy to have problems.


Today, I mainly share with you how to clean and maintain the film blowing machine and extruder. More importantly, I sorted out several common faults of the film blowing machine and their effective solutions.


Before startup, the following inspections shall be done:


PE film blowing machine shall first check the fastening of all connecting parts of the film blowing machine to prevent bolts from loosening;


The main engine gearbox and traction reduction gearbox shall be frequently filled with oil and replaced with gear oil (the oil level can reach the scale mark position), so as to ensure the normal operation of all rotating parts and prevent difficult operation and overheating damage;


When starting the main motor, start the motor first and then slowly accelerate, and stabilize after reaching the required speed; If the machine is shut down for maintenance, it shall be slowed down first and then shut down;


During preheating, the heating should not be too long or too high to avoid blockage of the material port; If possible, you can use the automatic temperature control system to set the upper and lower tolerance, and the temperature is automatically stable, convenient and safe;


After the main engine is turned on, pay close attention to the operation of the main engine, adjust, correct, electrical instruments and controllers in time, observe whether there is abnormality or damage, and repair and replace them to ensure their normal operation;


It is strictly prohibited to rotate without material. When the material barrel, tee and die head do not reach the required temperature, the main engine cannot be started;


The compressed air in the bubble tube shall be kept balanced, because the leakage of compressed air will be brought out during traction, so as to achieve the effect of timely supplement.

Common faults of film blowing machine and their solutions


Difficulty in mold drawing:


(1) Improper head temperature control: the head temperature shall be adjusted appropriately.


(2) Uneven die discharge: the die clearance shall be adjusted and the temperature of the head connector shall be properly adjusted at the same time.


(3) The molten material contains coke impurities: purify raw materials and clean the machine head and screw.


(4) Improper control of extrusion process conditions: the process conditions shall be adjusted appropriately.


Deflection of bubble tube:


(1) Body and die temperature is too high: reduce it appropriately.


(2) Head connector temperature is too high: reduce it appropriately.


(3) Uneven die discharge and uneven film thickness: properly adjust die clearance and head connector temperature.
