Technical Field
[0001] The utility model relates to the technical field of winding equipment, in particular to a single-filament winding device for a hollow fiber membrane spinning machine. Background Art
[0002] At present, the membrane separation technology is a separation technology widely used in the separation, concentration and purification of solution or gaseous substances. The micropores on the membrane wall are densely distributed. The stock solution passes through one side of the membrane under a certain pressure, and the solvent and small-molecule solutes pass through the membrane wall by filtration, while the macromolecule solutes are intercepted by the membrane to achieve the purpose of material separation and concentration. Among them, the hollow fiber membrane is a commonly used separation membrane in the membrane separation technology. Its shape is fibrous and it is hollow inside with a self-supporting effect. Compared with other membrane varieties in different forms, it has obvious advantages.
[0003] The hollow fiber membrane is mainly formed into continuous hollow filaments after processes such as spinning, water washing, drying and bending, and then the winding device bundles the filaments. After rotating a specified number of turns to obtain a specified number of filaments, cutting and bundling are carried out. During the winding process, for filaments with a larger diameter, single-filament winding is required. Since the existing spinning equipment generally extrudes multiple filaments simultaneously, multiple winding devices need to work simultaneously to meet the production requirements. Since most of the existing winding devices adopt a single-wheel and single-station winding mode, in the case of multiple filaments extruded simultaneously, multiple winding devices need to be arranged to meet the production requirements, which not only increases the equipment investment cost, but also has high requirements for the site and low production efficiency. Therefore, it is urgent to make necessary improvements and innovations to the existing winding equipment. Summary of the Utility Model

Detailed implementation manners
[0026] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited are not intended to limit the present utility model.
[0027] Embodiment, referring to Figures 1 to 7 As shown, a single-filament winding device for a hollow fiber spinning machine includes a frame 10 and a driving mechanism 20, a wire arranging mechanism 30, a speed regulating mechanism 40 and a winding wheel 50 all installed on the frame 10;
[0028] Winding wheels 50 are provided on both sides of the frame 10, and the number of winding wheels 50 on each side of the frame 10 is at least two. In this embodiment, two winding wheels 50 are provided on each side of the frame 10. The winding wheels 50 on the same side of the frame 10 are staggered in height, so that there are corresponding height differences and width position differences between the winding mechanisms, so as to independently wind the membrane filaments 80 without interference, facilitate manual loading and unloading, save space at the same time. The winding wheel 50 is installed on the driving mechanism 20, and the driving mechanism 20 drives the winding wheel 50 to rotate to provide power for winding the membrane filament 80. Each winding wheel 50 is correspondingly provided with a wire arranging mechanism 30 and a speed regulating mechanism 40. The membrane filament 80 led out from the spinning machine sequentially bypasses the speed regulating mechanism 40 and the wire arranging mechanism 30 and then winds around the corresponding winding wheel 50. The wire arranging mechanism 30 is used to arrange the membrane filament 80 wound on the winding wheel 50, and the speed regulating mechanism 40 is used to adjust the winding speed of the driving mechanism 20, as Figure 2 shown.
[0029] The utility model adopts a four-station integrated winding device, which can meet the production needs of multi-strand wire output and simultaneous winding, and can wind independently. The device adopts four-station winding, and each winding station adopts an independent control system. The four stations are respectively distributed on both sides of the frame 10, with two winding mechanisms on each side. There are corresponding height differences and width position differences between the winding mechanisms on each side, so as to wind the film wire 80 independently without interference, which is also convenient for manual loading and unloading, and saves space at the same time. During winding, a corresponding wire arranging mechanism 30 is also provided to adjust the position of the film wire 80 left and right, so that the film wire 80 can be evenly distributed on the winding wheel 50. At the same time, there is also a corresponding speed regulating mechanism 40 to adjust the speed of the winding wheel 50 in real time, so as to ensure that during winding, the winding speed of the film wire 80 can match the spinning speed, and keep the film wire 80 having a stable tension during the winding process.
[0030] In a specific embodiment of the utility model, the driving mechanism 20 includes a driving shaft 24 and a winding motor 22. The driving shaft 24 is horizontally installed on the frame 10 through a bearing seat 25. The winding wheel 50 is vertically installed at one end of the driving shaft 24 horizontally extending out of the frame 10. The winding motor 22 is installed on the frame 10 through a support 21. The winding motor 22 drives the driving shaft 24 to rotate through a synchronous belt 23, and then drives the winding wheel 50 on the winding shaft to rotate, so as to provide power for winding the film wire 80. A counting induction block 26 is also installed on the driving shaft 24, and the counting induction block 26 is used in cooperation with an optoelectronic sensor 27 installed on the frame 10 to record the number of turns of the driving shaft 24 rotating, so as to facilitate the control of the winding number of turns of the winding wheel 50.
[0031] The wire arranging mechanism 30 includes a bottom plate 31 installed on the frame 10, a wire arranging motor 32 and a reciprocating driving assembly both installed on the bottom plate 31. Two vertical guide rollers 36 are installed on the reciprocating driving assembly. The film wire 80 passes between the two guide rollers 36. The wire arranging motor 32 drives the guide rollers 36 to reciprocate linearly in the horizontal direction through the reciprocating driving assembly, so as to be able to arrange the film wire 80 wound on the winding wheel 50 left and right, and ensure that the film wire 80 can be evenly distributed on the winding wheel 50.
[0032] In a specific embodiment of the present utility model, the reciprocating drive assembly includes a reciprocating lead screw 33, a guide shaft 34 and a drive seat 35. The reciprocating lead screw 33 and the guide shaft 34 are arranged in parallel and both are horizontally rotatably mounted on the bottom plate 31. One end of the reciprocating lead screw 33 is coaxially connected to the power output shaft of the wire arranging motor 32 through a coupling. The wire arranging motor 32 drives the reciprocating lead screw 33 to rotate. The drive seat 35 is sleeved on the reciprocating lead screw 33 through a hole provided with a specific thread, and the specific thread matches the thread on the reciprocating lead screw 33. The drive seat 35 is also slidably sleeved on the guide shaft 34 through a through hole provided therein. The guide shaft 34 provides guidance for the horizontal reciprocating movement of the drive seat 35. Since the reciprocating lead screw 33 can enable the drive seat 35 to perform a reciprocating movement along the guide shaft 34 without changing the rotation direction of the main shaft, in essence, the reciprocating lead screw is a form of a spatial cam pair, and its manifestation is two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. Through the rotation of the lead screw, the side surface of the thread groove pushes the drive seat 35 placed in the thread groove to perform an axial reciprocating movement; the guiding roller 36 is vertically rotatably mounted on the drive seat 35. The wire arranging motor 32 drives the reciprocating lead screw 33 to rotate, and then drives the drive seat 35 to horizontally reciprocate along the guide shaft 34. The two guiding rollers 36 drive the film wire 80 therebetween to swing in the left-right direction, so as to realize the left-right arrangement of the film wire 80 wound on the take-up wheel 50.
[0033] In a specific embodiment of the present utility model, the speed regulating mechanism 40 includes a vertical plate 41 mounted on the frame 10, and a rotating shaft 42 horizontally rotatably mounted on the vertical plate 41. One end of the rotating shaft 42 is connected to an angle sensor 43, and the angle sensor 43 is fixed to the vertical plate 41 through a bracket 49. A swing rod 44 is fixed to the other end of the rotating shaft 42. Counterweights 46 and wire guide wheels 47 are respectively installed at both ends of the swing rod 44. The counterweight 46 is used to balance the gravity at the end where the wire guide wheel 47 is located. The film wire 80 bypasses the wire guide wheel 47. The axis where the wire guide wheel 47 is located is parallel to the rotating shaft 42. Two limiting rods 45 are also fixed to the vertical plate 41. The swing rod 44 swings between the two limiting rods 45. The upper and lower limits of the swing of the swing rod 44 are restricted by the two limiting rods 45 to prevent the swing amplitude of the swing rod 44 from being too large. A stop rod 48 is further provided below the wire guide wheel 47. The stop rod 48 is parallel to the rotating shaft 42. A gap is provided between the stop rod 48 and the rim of the wire guide wheel 47. The film wire 80 passing through the wire guide wheel 47 is restricted by the stop rod 48 to prevent the film wire 80 from coming off the groove. During use, the film wire 80 bypasses below the wire guide wheel 47 of the speed regulating mechanism 40, which is equivalent to the wire guide wheel 47 being supported by the film wire 80. Therefore, the downward swing degree of the wire guide wheel 47 indirectly reflects the tension degree of the film wire 80. The downward swing degree of the wire guide wheel 47 is then detected by the angle sensor 43. The signal detected by the angle sensor 43 is fed back to the driving mechanism 20 that controls the rotation of the take-up wheel 50. Furthermore, the driving mechanism 20 can control the take-up speed of the take-up wheel 50 according to the electrical signal fed back by the angle sensor 43. Thus, a dynamic balance is achieved between the take-up speed of the film wire 80 and the spinning speed of the spinning machine.
[0034] In a specific embodiment of the present utility model, each take-up wheel 50 is correspondingly provided with a set of transition rollers 60 mounted on the frame 10. The transition rollers 60 are horizontally arranged and used to support the film wire 80. The number of each set of transition rollers 60 is at least one. The number of transition rollers 60 is set according to needs. And there is at least one transition roller 60 between the speed regulating mechanism 40 and the wire arranging mechanism 30. Since the film wire 80 needs to bypass below the wire guide wheel 47 of the speed regulating mechanism 40, it needs to be transitioned by a transition roller 60 in order to smoothly lead the film wire 80 from the wire arranging mechanism 30 to the take-up wheel 50.
[0035] In a specific embodiment of the present utility model, on both sides of the rim of the winding wheel 50, there are provided retaining edges 51. The space between the two retaining edges 51 is used for winding the film filaments 80. On the rim of the winding wheel 50, there is also provided a cutting groove 52 arranged along its generatrix direction. After the winding is completed, the film bundle on the winding wheel 50 is cut off along the cutting groove 52 by a tool, and then a whole film bundle formed after being cut short can be taken off from the winding wheel 50. The retaining edges 51 where both ends of the cutting groove 52 are located are cut off to form notches. Outside one of the notches, there is provided a wire clamping assembly 53 for binding the end of the film filament 80. The wire clamping assembly 53 includes a column 54 installed on the side surface of the winding wheel 50 and two clamping blocks 55 hinged in a scissor shape. Between the two clamping blocks 55, there is provided a rubber strip. Due to the elastic tension of the rubber strip, the two clamping blocks 55 are always in a clamped state. During use, after the end of the film filament 80 is wound around the column 54 for multiple turns, the free end of the film filament 80 is clamped between the two clamping blocks 55, thereby realizing the fixation of the end of the film filament 80. Below each winding wheel 50, there is provided a water tank 70. The winding wheel 50 is partially located inside the corresponding water tank 70. During the winding process, the winding wheel 50 will pass the collected film filaments 80 through the pure water in the water tank 70. On the one hand, the pure water in the water tank 70 can dilute a part of the solvent on the film filaments 80, and at the same time, it can keep the filament bundle in a wet state, and it is not easy to break the filaments during the winding traction.
[0036] The above embodiments are only preferred embodiments given to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model is subject to the claims.
