At present, the most common membrane filament cutting method is manual cutting method using scissors, cutting knife and the like, but the production efficiency of manual cutting method is low, and the cutting direction is not perpendicular to the membrane filament, so that the membrane filament cutting surface is uneven, affecting the product quality.

[0003] To solve the above technical problems, the patent number ZL202123025299.0 (authorized publication number CN216803629U) discloses a membrane filament cutting device, which comprises a supporting seat, a supporting seat, a first cutting knife and a second cutting knife. The supporting seat is detachably placed on the supporting seat, and the supporting seat is provided with a limiting hole penetrating through the supporting seat. The first cutting knife and the second cutting knife are respectively located on the two sides of the supporting seat in the axial direction of the limiting hole. The first end of the first cutting knife is rotationally connected with the supporting seat, and the first end of the second cutting knife is rotationally connected with the supporting seat.

But the above-mentioned membrane filament cutting device has the following use limitations: first, the membrane filament to be cut needs to be fixed in turn through the first fixed, limiting hole and second fixed hole in a straight line, because the hole diameter of the first fixed, limiting hole and second fixed hole is limited, so the fixing operation of the membrane filament to be cut is difficult.

Second, the membrane filament cutting device only fixes the two ends of the membrane filament to be cut by the first fixed, limiting hole and second fixed hole, and this fixing method cannot keep the membrane filament to be cut in a stable state, which causes cutting difficulty. Therefore, the prior art needs to be further improved. UTILITY MODEL CONTENTS
