In the production process of hollow fiber membranes, the manufactured slender hollow fibers are processed through processes such as gelation, water washing, drying, bending, etc. to form continuous membrane filaments, which are then collected into bundles by a wire collecting machine and rotated a specified number of times to obtain a specified number of roots. When the number of wire collecting turns in the wire collecting machine reaches the requirement, the membrane filaments are wrapped with a wire wrapping film, and then the two butt edges of the wire wrapping film are bonded together, and then several membrane filaments are wrapped together to form a bundle, and then the wrapped membrane filaments are sheared off the wire collecting wheel of the wire collecting machine to form a membrane bundle of a certain length.

[0045] When the cutting device of the utility model is working: the position of the cutting blade 402 is adjusted to keep the preset position state by changing the position of the adjusting plate 501 and the rotating base 508, and then the position is locked by the corresponding bolt or nut 609, and then the width adjustment mechanism, that is, by rotating the hand wheel 610, drives the lead screw 608 to rotate, and then drives the translation plate 601 to move, so as to adjust the distance between the two groups of cutting blades 402 so that the distance meets the cutting requirements, and then the translation plate 601 is locked on the fixed block 605 by bolts, and the lead screw 608 is locked by the locking device 612, and finally the film bundle 303 to be cut is clamped on the carrier 300, and the linear drive module 200 drives the carrier 300 to approach the cutting device 400 at a set speed, and then the film bundle 303 to be cut is clamped on the carrier 300. The cutting blade 402 rotating at high speed cuts both ends of the membrane bundle 303 on the carrier 300 at the same time. During the cutting process, the positive pressure airflow generated by the positive pressure blowing system is blown toward the cutting blade 402 through the cooling air pipe 702, thereby blowing and cooling the cutting blade 402, which can effectively prevent the membrane bundle 303 from melting due to excessive temperature of the blade surface. At the same time, the static electricity removal device works and generates air with a large amount of positive and negative ions, and blows the air with positive and negative ions through the static electricity removal tube 703 to the contact position between the blade surface and the membrane bundle 303, so as to neutralize the static electricity generated by the cutting blade 402 in the process of cutting the membrane bundle 303, reduce the adhesion of the wire bundle to the membrane bundle 303 or blades and other equipment due to static electricity, and enable the wire suction hood 701 to collect the cut broken wires through negative pressure.
