Description

Technical Field

[0001] This utility model relates to the field of cutting mechanism technology, and in particular to an automatic cutting mechanism for ultrafiltration membrane fibers. Background Technology

[0002] Ultrafiltration membrane fibers are a high-tech filtration material, usually made of polymer materials such as polysulfone, polyethersulfone, or polyvinylidene fluoride. They have a hollow internal structure and a surface covered with nanoscale pores. This material has the characteristics of acid and alkali resistance, oxidation resistance, and high mechanical strength. It is widely used in drinking water purification, industrial wastewater treatment, food concentration, and medical separation, and has the advantages of both high-efficiency filtration and long service life.

[0003] In practical applications, ultrafiltration membrane fibers are often combined and processed according to specific needs. The processing methods include tightly bundling them into cylindrical filter cartridges or arranging them side-by-side into curtain-like structures to achieve precise filtration of water sources. However, the cutting process of ultrafiltration membrane fibers is crucial in the manufacturing process of filter cartridges or curtain-like components. Currently, the industry commonly uses manual cutting methods, which are not only inefficient and slow but also difficult to guarantee cutting accuracy and consistency, thus affecting overall production efficiency and product quality. Based on this, this utility model is proposed. Utility Model Content

[0014] Compared with the prior art, this utility model provides an automatic cutting mechanism for ultrafiltration membrane fibers, which has the following beneficial effects:

[0015] 1. The automatic cutting mechanism for ultrafiltration membrane fibers, by setting up a sliding block, a sliding plate, a support block and a squeezing block, can straighten the ultrafiltration membrane fibers when cutting them, making it easier for the blade to cut the ultrafiltration membrane fibers and making the cut smoother.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1: Refer to Figures 1-8 An automatic cutting mechanism for ultrafiltration membrane fibers includes a base 1 and a support frame 2. It further includes: an active roller 12 and a driven roller 13 for conveying ultrafiltration membrane fibers are rotatably connected to the base 1; a conveyor belt 31 is mounted on the base 1; a sliding plate 5 is slidably connected to the base 1; and a cutting opening 15 is provided on the base 1. A blade holder 23 is slidably connected to the support frame 2; blades 24 are mounted on the blade holder 23; sliding blocks 26 are connected to both ends of the blade holder 23; pressing blocks 272 are connected to the sliding blocks 26; and wiping blocks 25 are slidably connected to the blade holder 23. When the blade holder 23 descends to cut the ultrafiltration membrane fibers below, the pressing blocks 272 and the sliding plate 5 together clamp the ultrafiltration membrane fibers and stretch them to both sides. When the blade holder 23 rises to its original position, the wiping blocks 25 move down to wipe the surface of the blades 24.

[0031] In this invention, the produced ultrafiltration membrane fibers can be directly guided between the active roller 12 and the driven roller 13, and the active roller 12 and the driven roller 13 convey the ultrafiltration membrane fibers to the conveyor belt 31, and the conveyor belt 31 transports the ultrafiltration membrane fibers out. The knife holder 23 is set between the conveyor belt 31 and the active roller 12, and the cutting opening 15 is located directly below the knife holder 23 and corresponds to the blade 24. The knife holder 23 can cut the ultrafiltration membrane fibers above the cutting opening 15 by driving the blade 24 to move down into the cutting opening 15.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, when the blade holder 23 moves the blade 24 downward to cut, it will cause the extrusion block 272 and the sliding plate 5 to clamp the ultrafiltration membrane fiber. During the downward movement, the extrusion block 272 and the sliding plate 5 will move the clamped ultrafiltration membrane fiber to both sides to straighten the ultrafiltration membrane fiber, making it easier for the blade 24 to cut the ultrafiltration membrane fiber and making the cut smoother.

[0033] When the blade holder 23 rises to its reset position, the wiping block 25 moves downward to wipe the blade 24, thereby preventing excessive debris from adhering to the blade 24. When not in use, the wiping block 25 can protect the blade 24 from damage. When cleaning, the user only needs to wipe the bottom of the wiping block 25, which can prevent the user from scratching their arm when cleaning the blade 24. Preferably, the surface of the wiping block 25 is made of fabric material, which can ensure that it can come into contact with the blade 24 for wiping.

[0034] Example 2: Refer to Figures 1-8 Similar to Embodiment 1, but with a further improvement: a cylinder 21 is mounted on the support frame 2, and a sliding support plate 22 is connected to the output end of the cylinder 21. The knife holder 23 is mounted on the sliding support plate 22, and a sliding groove 221 is provided on the sliding support plate 22. A sliding inclined groove 14 is provided on the base 1. A sliding block 26 is slidably connected to the sliding groove 221 and the sliding inclined groove 14 respectively via a rotating shaft. A connecting rod 262 is rotatably connected to both ends of the sliding block 26, and the other end of the connecting rod 262 is rotatably connected to both ends of the wiping block 25. When the sliding block 26 moves to both sides, the wiping block 25 is pulled upward by the connecting rod 262. A first elastic component 261 is connected to the sliding block 26, and a support block 27 is connected to the other end of the first elastic component 261. A second elastic component 271 is connected between the support block 27 and the pressing block 272. A transition plate 52 is provided on the base 1, and a second compression spring 51 is connected between the transition plate 52 and the sliding plate 5. The sliding block 23 is mounted on the sliding support plate 23. A sliding top block 41 is connected to the blade 24. A sliding rod 42 is fixedly connected to the blade holder 23. A limit block 43 is slidably connected to the sliding rod 42. A first compression spring 44 is connected to the top of the limit block 43 and the sliding rod 42. When the sliding top block 41 slides to below the limit block 43, the sliding top block 41 is locked and limited by the limit block 43. A first servo motor 11 and a second servo motor 3 are installed on the base 1. The output end of the first servo motor 11 is connected to the drive roller 12. A drive gear 121 is connected to the drive roller 12. A driven gear 131 is connected to the driven roller 13. The drive gear 121 and the driven gear 131 mesh. The output end of the second servo motor 3 is connected to the roller of the conveyor belt 31. A first gear 311 is connected to the roller of the conveyor belt 31. A second gear 321 is rotatably connected to the base 1. The second gear 321 meshes with the first gear 311. A conveyor roller 32 is connected to the second gear 321.

[0035] In this utility model, such as Figure 5As shown, the sliding groove 14 consists of a vertical upper groove and an inclined lower groove. The top and bottom of the side end of the sliding block 26 are connected to cylindrical rotating shafts. The top rotating shaft is slidably connected in the sliding groove 221, and the bottom rotating shaft is slidably connected in the sliding groove 14. Thus, when the sliding support plate 22 moves the sliding block 26 downward, the sliding block 26 first moves vertically downward. When the lower rotating shaft enters the lower half of the inclined groove of the sliding groove 14, the sliding block 26 will be guided to move in the direction of the inclined groove.

[0036] Both the first elastic component 261 and the second elastic component 271 are composed of a telescopic rod and a compression spring. The telescopic rod limits the telescopic distance, and the compression spring provides an outward pushing force. Figure 6 and Figure 7 As shown, when the sliding block 26 moves vertically downward, the squeezing block 272 will contact the sliding plate 5 to clamp the ultrafiltration membrane fiber together. This clamping force is provided by the first elastic component 261. When the sliding block 26 starts to move to both sides, the ultrafiltration membrane fiber will be pulled to both ends and stretched. This pulling force is provided by the first elastic component 261.

[0037] like Figure 4 As shown, a second compression spring 51 is connected between the sliding plate 5 and the transition plate 52. When the tool holder 23 is reset, the second compression spring 51 pushes the sliding plate 5 to reset.

[0038] A connecting rod 262 is connected between the sliding block 26 and the wiping block 25 via a rotating shaft. When the sliding block 26 moves to the sides, it pulls the wiping block 25 upward to expose the blade 24. When it is reset, the sliding block 26 moves towards the center and the wiping block 25 moves downward to wipe the surface of the blade 24.

[0039] like Figure 4 As shown, the sliding top block 41 is provided with a slot, and the limiting block 43 is provided with a locking block. When the sliding top block 41 is slid to the bottom of the limiting block 43, the locking block is pushed into the slot by the second compression spring 51 to restrict the sliding top block 41 from moving back. At this time, the bottom protrusion of the sliding top block 41 abuts against the sliding groove 221, thereby completing the limiting of the sliding top block 41. The sliding top block 41 can work with the blade holder 23 to complete the limiting installation of the blade 24. When the blade 24 needs to be removed and replaced, simply pull the limiting block 43 upward and slide the sliding top block 41 out to release the limiting of the blade 24. At this time, simply place the stop block at the cutting opening 15 and perform the cutting operation again so that the blade 24 can be pushed out by the stop block. The user can then take out the blade 24 by pushing out the part.

[0040] The first servo motor 11 drives the active roller 12 and the active gear 121 to rotate, which in turn drives the driven gear 131 and the driven roller 13 to rotate in the opposite direction. This enables the active roller 12 and the driven roller 13 to transport the ultrafiltration membrane fibers. The second servo motor 3 drives the rotating shaft of the conveyor belt 31 and the first gear 311 to rotate, which in turn drives the second gear 321 and the conveyor roller 32 to rotate. This allows the cut ultrafiltration membrane fibers to be transported out. The first gear 311 and the second gear 321 are the same size, and the rotating shaft of the conveyor belt 31 and the conveyor roller 32 are the same size, which ensures that the conveying speed of the conveyor belt 31 and the conveyor roller 32 is the same.

[0041] By setting a long-handled cutter holder 23, multiple flat ultrafiltration membrane fibers can be cut simultaneously, thus improving cutting efficiency.

[0042] When using the device, the user guides the produced ultrafiltration membrane fibers through the drive roller 12 and driven roller 13, and then guides them between the conveyor roller 32 and the conveyor belt 31, so that the ultrafiltration membrane fibers are continuously conveyed. When they are conveyed to a certain length, the cylinder 21 drives the cutter holder 23 to move down to complete the cutting of the ultrafiltration membrane fibers. After cutting, the user continues to guide the ultrafiltration membrane fibers between the conveyor roller 32 and the conveyor belt 31 to continue the cutting, and so on.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
