An anti-slip conveyor roller 5 is rotatably connected to the lower middle part of the C-shaped conveyor frame 4. The middle part of the anti-slip conveyor roller 5 is rotatably connected to the C-shaped conveyor frame 4 via a rotating shaft 501. A driving device 6 is fixedly connected to one side of the C-shaped conveyor frame 4. A servo motor module 601 is fixedly installed inside the driving device 6. One end of the rotating shaft 501 extends into the driving device 6 and is fixedly connected to the output shaft of the servo motor module 601. A C-shaped lifting frame 403 is provided at the upper middle part of the C-shaped conveyor frame 4. A second hydraulic rod 401 is fixedly connected to the middle of the upper end of the conveyor frame 4. The telescopic end of the second hydraulic rod 401 passes through the C-shaped conveyor frame 4 and is fixedly connected to the middle of the upper end of the C-shaped lifting frame 403. A pressure roller 404 is rotatably connected to the inner side of the C-shaped lifting frame 403. Multiple hollow fiber films are pre-passed through the pressure roller 404 and the anti-slip conveyor roller 5 at equal intervals. The C-shaped lifting frame 403 and the pressure roller 404 are driven to descend as a whole by the second hydraulic rod 401, so that the pressure roller 404 presses the multiple hollow fiber films onto the anti-slip conveyor roller 5. The anti-slip conveyor roller 5 is driven to rotate by the servo motor module 601, and the hollow fiber films are conveyed when the hollow fiber films are cut.

[0018] Please see Figure 3 and Figure 4A guide cutting seat 2 is fixedly connected to the upper end of the cutting table 1. Multiple longitudinal guide holes 201 are fixedly connected at equal intervals in the middle of the guide cutting seat 2. A flared opening 204 is provided on the front face of the guide cutting seat 2 at the front end of each guide hole 201. Multiple hollow fiber membranes are pre-passed between the pressure roller 404 and the anti-slip conveying roller 5 at equal intervals and then inserted into the guide holes 201 through the flared openings 204. The anti-slip conveying roller 5 rotates to convey the multiple hollow fiber membranes backward through the guide holes 201. When the hollow fiber membrane moves to the upper end of the cutting groove 203 in the middle of the guide hole 201, the anti-slip conveying roller 5 stops rotating. A rectangular observation groove 2 is provided between the middle of the upper face of the guide cutting seat 2 and the middle of the multiple guide holes 201. 02. A cutting groove 203 is provided in the middle of multiple guide through holes 201 and at the lower end of the rectangular observation groove 202. A C-shaped fixing frame 3 is fixedly connected to the upper end of the cutting table 1. A knife holder 303 is lifted and connected to the middle of the inner side of the C-shaped fixing frame 3. A cutter 304 is fixedly connected to the middle of the lower end of the knife holder 303. A first hydraulic rod 301 is fixedly connected to the middle of the upper end of the C-shaped fixing frame 3. The lower end of the telescopic end of the first hydraulic rod 301 passes through the C-shaped fixing frame 3 and is fixedly connected to the middle of the upper end of the knife holder 303. The two sides of the middle of the upper end of the knife holder 303 are connected to the C-shaped fixing frame 3 through the first guide mechanism 302. The first hydraulic rod 301 drives the knife holder 303 and its lower cutter 304 to descend and insert into the cutting groove 203 to cut the hollow fiber membrane.

[0019] Please see Figure 1 and Figure 4 The cutting table 1 has a receiving box 101 at the rear end. After the hollow fiber membrane is cut, the anti-slip conveying roller 5 continues to drive the hollow fiber membrane to move backward so that the next cutting position moves to the upper end of the cutting groove 203. When the hollow fiber membrane moves backward, it will push the hollow fiber membrane after being cut at the rear end of the cutting position to be discharged from the rear end of the guide hole 201 and fall into the receiving box 101 for collection.

[0020] Working Principle: In operation, multiple hollow fiber membranes are pre-placed at equal intervals through the gap between the pressure roller 404 and the anti-slip conveyor roller 5. The C-shaped lifting frame 403 is driven downwards by the second hydraulic rod 401, causing the pressure roller 404 to press the membrane fibers firmly against the surface of the anti-slip conveyor roller 5. The servo motor module 601 is activated, driving the anti-slip conveyor roller 5 to rotate, guiding the membrane fibers through the trumpet-shaped opening 204 into the guide hole 201 for rearward transport. The position of the membrane fibers is monitored in real-time through the rectangular observation slot 202. Transport stops when the cutting point reaches above the cutting groove 203. The first hydraulic rod 301 drives the cutter holder 303 downwards, causing the cutter 304 to pass through the cutting groove 203 for precise cutting. The anti-slip conveyor roller 5 then continues to transport the membrane fibers, bringing the next segment to the cutting position. Simultaneously, the cut segment is pushed out from the rear end of the guide hole 201 and falls into the receiving box 101 for automatic collection. The entire process utilizes hydraulic drive and a servo motor to achieve continuous automatic feeding, positioning cutting, and collection.
