[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an immersion hollow fiber ultrafiltration membrane cutting device, which has the following beneficial effects:

[0017] 1. This submerged hollow fiber ultrafiltration membrane cutting equipment, after placing the ultrafiltration membrane body, starts the drive motor to drive the transmission belt to rotate inside the inner groove. The transmission belt first rotates and drives the collar to rotate the cutting blade shaft. When the cutting blade shaft drives the two cutting blades on both sides to rotate towards the ultrafiltration membrane body located on the vertical beam inside the groove, the cutting blades cut both ends of the ultrafiltration membrane body located on the vertical beam. When the cutting blades rotate, they drive the torsion springs on both sides to elastically contract. When the transmission belt rotates, it will synchronously drive the connecting shaft and... The pull rope is wound around the outside of the connecting shaft. Before the cutting blade rotates to complete the cutting and begins to reset, the connecting shaft is wound and pulls the pull plate, which drives the synchronous rotating shaft to rotate and open the side panels. At this time, the ultrafiltration membrane body located in the guide groove slides down. Before the ultrafiltration membrane body slides to the top of the machine, the cutting blade performs a pre-elastic reset. After the cutting blade resets, the ultrafiltration membrane body slides onto the two vertical beams, thus completing the automatic cutting process of both ends of the ultrafiltration membrane body, reducing manual labor, and effectively improving the efficiency of ultrafiltration membrane body cutting process.

[0018] 2. This submersible hollow fiber ultrafiltration membrane cutting equipment places multiple ultrafiltration membrane bodies directly inside the guide trough. The ultrafiltration membrane bodies are located on the side of the guide plate away from the machine platform. Simultaneously, the ultrafiltration membrane bodies are subjected to gravity within the guide trough and roll towards the two ultrafiltration membrane clamping components. The ultrafiltration membrane bodies roll under gravity and impact the rounded corners of the two pressure frames. The ultrafiltration membrane bodies push the two pressure frames and cause the pressure frames to rise outside the vertical beams. When the pressure frames rise, they drive the movable plate and cause the vertical spring to contract. At the same time, the thrust generated by the impact of the ultrafiltration membrane bodies is greater than the elastic force generated by the contraction of the vertical spring. At this time, the two ends of the ultrafiltration membrane bodies roll down to the top of the two vertical beams under gravity. Since the two ends of the ultrafiltration membrane bodies are limited by the inner walls of the guide trough, the two ends of the ultrafiltration membrane bodies can roll down stably and smoothly onto the two vertical beams, achieving the effect of automatically and stably positioning the two ends of the ultrafiltration membrane bodies.

[0019] 3. This submersible hollow fiber ultrafiltration membrane cutting equipment places the ultrafiltration membrane body on two vertical beams and cuts it with a cutting blade. The waste material cut at both ends of the ultrafiltration membrane body falls downward into the waste chute through the gap in the chute. Since the waste chute is inclined downward, the waste material slides down into the inside of the waste bin under the downward gravity and is stored there, achieving the effect of quickly collecting the cut waste material.

[0020] 4. This submersible hollow fiber ultrafiltration membrane cutting equipment aligns and cuts the two ends of the ultrafiltration membrane body. The entire ultrafiltration membrane body falls downward into the discharge trough and slides down above the guide frame via the discharge trough. The ultrafiltration membrane body is blocked by the baffle and falls above the feeding plate. The ultrafiltration membrane body lands on the feeding plate and applies gravity to the feeding plate, causing the feeding plate to move downward. The feeding plate moves downward inside the guide frame and drives the extension plates on both sides to elastically extend the elastic rope downward. The elasticity of the elastic rope is less than the gravity applied by the ultrafiltration membrane body to the feeding plate, and the surface of the feeding plate is tilted away from the machine. Therefore, when the feeding plate moves downward to the lower part of the guide frame, the ultrafiltration membrane body is guided by the tilt of the feeding plate and slides down into the collection box for collection, achieving the effect of quickly and uniformly collecting the cut ultrafiltration membrane body.

[0021] 5. This submerged hollow fiber ultrafiltration membrane cutting equipment fixes the ultrafiltration membrane body on two vertical beams. When the cutting blade cuts the ultrafiltration membrane body, it first cuts from the bottom of the ultrafiltration membrane body from below. The cutting blade cuts the ultrafiltration membrane body from bottom to top, thus applying pressure to the ultrafiltration membrane body towards the surface of the vertical beams. At this time, the ultrafiltration membrane body is blocked by the vertical beams and positioned between the vertical beams and the pressure frame, making the ultrafiltration membrane body more stable during cutting and improving the quality of the ultrafiltration membrane body after cutting.

[0037] When using,

[0038] The first step involves placing multiple ultrafiltration membrane bodies 14 directly inside the guide groove 12. The ultrafiltration membrane bodies 14 are located on the side of the baffle plate 61 away from the machine platform 1. Simultaneously, the ultrafiltration membrane bodies 14 are subjected to gravity within the guide groove 12 and roll towards the two ultrafiltration membrane clamping components 2. The ultrafiltration membrane bodies 14 roll under gravity and impact the rounded corners of the two pressure frames 22. The ultrafiltration membrane bodies 14 push the two pressure frames 22, causing the pressure frames 22 to rise outside the upright beam 21. When the pressure frames 22 rise, they drive the movable plate 25 and cause the vertical spring 27 to contract. At the same time, the thrust generated by the impact of the ultrafiltration membrane bodies 14 is greater than the elastic force generated by the contraction of the vertical spring 27. At this time, the two ends of the ultrafiltration membrane bodies 14 roll down to the top of the two upright beams 21 under gravity. Since the two ends of the ultrafiltration membrane bodies 14 are limited by the two sides of the inner wall of the guide groove 12, the two ends of the ultrafiltration membrane bodies 14 can roll down stably and smoothly onto the two upright beams 21, achieving the effect of automatically and stably positioning the two ends of the ultrafiltration membrane bodies 14.

[0039] The second step involves placing the ultrafiltration membrane body 14, then starting the drive motor 68 to rotate the transmission belt 69 inside the inner groove 72. The transmission belt 69 first rotates, causing the collar 71 to rotate the cutting blade shaft 46. When the cutting blade shaft 46 drives the two cutting blades 42 to rotate inside the groove 41 towards the ultrafiltration membrane body 14 located on the vertical beam 21, the cutting blades 42 cut both ends of the ultrafiltration membrane body 14 on the vertical beam 21. As the cutting blades 42 rotate, they cause the two torsion springs 45 on both sides to elastically contract. Simultaneously, the rotation of the transmission belt 69 drives the connecting shaft 65 and pulls the rope 64... The connecting shaft 65 is wound around the outside. Before the cutting blade 42 rotates to complete the cutting and begins to reset, the connecting shaft 65 is wound around and pulls the pull plate 63, which drives the synchronous rotating shaft 74 to rotate and open the side panels 61. At this time, the ultrafiltration membrane body 14 located in the guide groove 12 slides down. Before the ultrafiltration membrane body 14 slides down to the top of the machine platform 1, the cutting blade 42 is pre-elastically reset. After the cutting blade 42 is reset, the ultrafiltration membrane body 14 slides onto the two vertical beams 21, thereby completing the automatic cutting process of both ends of the ultrafiltration membrane body 14, reducing manual labor, and effectively improving the efficiency of cutting the ultrafiltration membrane body 14.

[0040] The third step involves placing the ultrafiltration membrane body 14 on two upright beams 21 and cutting it with the cutting blade 42. The waste material cut off at both ends of the ultrafiltration membrane body 14 falls downward into the waste chute 51 through the gap in the trough 23. Since the waste chute 51 is inclined downward, the waste material slides down into the inside of the waste bin 52 under the downward force of gravity for storage, thus achieving the effect of quickly collecting the cut waste material.

[0041] In the fourth step, after aligning and cutting both ends of the ultrafiltration membrane body 14, the entire ultrafiltration membrane body 14 falls downward into the discharge trough 13 and slides down above the guide frame 32 via the discharge trough 13. The ultrafiltration membrane body 14 is blocked by the baffle 33 and falls above the discharge plate 35. The ultrafiltration membrane body 14 falls on the discharge plate 35 and applies gravity to the discharge plate 35, causing the discharge plate 35 to move downward. The discharge plate 35 moves downward inside the guide frame 32 and drives the extension plates 37 on both sides to make the elastic rope 36 extend downward elastically. The elasticity of the elastic rope 36 is less than the gravity applied by the ultrafiltration membrane body 14 to the discharge plate 35, and the surface of the discharge plate 35 is inclined to the side away from the machine 1. Therefore, when the discharge plate 35 moves downward to the lower part of the outside of the guide frame 32, the ultrafiltration membrane body 14 is guided by the inclination of the discharge plate 35 to slide down into the collection box 31 for collection, achieving the effect of quickly and uniformly collecting the cut ultrafiltration membrane body 14.
