The utility model is applicable to the field of detection equipment, and provides a membrane filament tension detection device of an immersion type
ultrafiltration membrane, which comprises a base plate and a locking cylinder, the base plate and the locking cylinder are fixedly arranged, the front end of the locking cylinder is rotatably provided with a torsion round tube, and the torsion round tube is connected to a torsion mechanism; a telescopic column is slidably inserted into the torsion round
pipe in a penetrating mode, and a guide groove mechanism is arranged between the torsion round
pipe and the telescopic column. When the membrane
filament winding device is used, membrane filaments wind around three groups of arc-shaped grooves and then are wound on the winding roller, at the moment, the locking air cylinder drives the locking
square rod to stretch into the locking square opening to fix the discharging roller and the winding roller, and the electric push rod drives the telescopic column to contract towards the interior of the torsion round
pipe; the expansion tiles on the outer sides of the torsion round pipe and the telescopic column expand towards the outer side, then the membrane filaments on the outer sides of the expansion tiles are subjected to tension, the tension sensor on the output rod of the electric push rod can calculate the tension of the membrane filaments, and therefore the function of batch detection is achieved.
