Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber membrane filament production technology, and in particular to an adjustable-size, modular hollow fiber membrane filament take-up wheel. Background Technology
[0002] Hollow fiber membrane fibers are a type of synthetic semi-permeable membrane material, formed through solution spinning or melt spinning. They utilize the diffusion of solvents and non-solvents to create a porous structure, with a dense surface layer and an internal finger-like pore support layer together forming an asymmetric membrane. During production, hollow fiber membrane fibers are wound up using a take-up roller, then cut and bundled using specific tools, and finally dried for later use.
[0003] Most existing take-up rollers are of fixed size, with fixed winding width and diameter, and cannot be adjusted according to different production needs.
[0004] In actual production, hollow fiber membrane filaments of different specifications may require take-up rollers of different diameters for winding. Moreover, in some special production processes, the size of the take-up rollers also needs to be flexibly adjusted. Fixed-size take-up rollers cannot meet these diverse needs, forcing manufacturers to prepare a variety of take-up rollers of different sizes. This increases production costs and equipment management difficulties. At the same time, frequent disassembly and assembly not only wastes time but also increases the wear and tear on the take-up roller connectors.
[0005] Furthermore, when a take-up roller experiences partial damage, its overall structure often necessitates replacement of the entire roller, resulting in resource waste. Therefore, developing a size-adjustable, modular hollow fiber membrane take-up roller is of significant practical importance. Utility Model Content
[0006] In view of this, the purpose of this utility model is to propose an adjustable-size, modular hollow fiber membrane filament take-up wheel to solve the problems in the prior art.
[0007] To achieve the above objectives, this utility model provides a size-adjustable, modular hollow fiber membrane filament take-up wheel, including a fixed wheel rotatably connected to a washing tank via a central shaft. The take-up wheel further includes:
[0008] A splicing wheel is fixedly connected to a fixed wheel. The splicing wheel is composed of several arc-shaped combination plates connected in sequence. The splicing wheel is circular and fits around the outside of the fixed wheel, and there is a gap between the splicing wheel and the fixed wheel.
[0009] Several connecting parts are located in the gap between the splicing wheel and the fixed wheel, and the upper and lower ends of the connecting parts are detachably connected to the splicing wheel and the fixed wheel, respectively.
[0010] Furthermore, the fixed wheel includes a cylindrical wheel disc and protruding edges fixedly connected to the two sides of the wheel disc, and the outer edge of the protruding edges is provided with several connecting grooves.
[0011] Furthermore, a limiting ring is provided at the connection between the central shaft and the cleaning tank, and the central shaft is also connected to the output shaft of the drive component.
[0012] Furthermore, the outer side of the combined plate is provided with a flow guide groove, and the upper and lower sides of the flow guide groove are respectively provided with a wire hanging groove and a screw hole.
[0013] Furthermore, the splicing wheels are provided in various types, each with a different diameter, and the combined plates that make up the same size splicing wheels have the same size and curvature.
[0014] Furthermore, the connectors are provided in various types, each with a different length, to accommodate splicing wheels of different diameters.
[0015] Furthermore, the connector includes a sleeve and a lower screw and an upper screw threadedly connected in the sleeve. The lower screw is threadedly connected to a fixed wheel, and the upper screw is threadedly connected to a splicing wheel.
[0016] Furthermore, the lengths of the lower screw and the upper screw are the same as the length of the sleeve, and a washer and a nut are also fitted on the lower screw.
[0017] The beneficial effects of this utility model are as follows: 1. The splicing wheel is composed of multiple combination plates, so different diameter splicing wheels can be formed by using combination plates with different arc dimensions. This allows for easy adjustment of the overall size of the entire take-up wheel, meeting the take-up requirements of hollow fiber membrane filaments of different specifications and improving production efficiency.
[0018] 2. The splicing wheel used for wire take-up adopts a splicing structure. Therefore, when a splicing unit (combination plate) of the splicing wheel is damaged, only that splicing unit needs to be replaced, without replacing the entire splicing wheel or the entire take-up wheel. This greatly reduces maintenance costs and resource waste.
[0019] 3. The connector can be composed of a sleeve and a lower screw and an upper screw, allowing the length of the connector to be adjusted. This enables it to adapt to splicing wheels of various diameters. The fixed wheel has a connecting groove, and the splicing wheel has a screw hole for threaded connection with the lower and upper screws, ensuring the overall stability of the take-up wheel.
[0020] 4. The outer side of the assembly plate is equipped with a guide groove. When the take-up wheel starts to rotate, it will carry the cleaning fluid in the cleaning tank. The guide groove on the assembly plate allows the carried cleaning fluid to flow back into the cleaning tank, avoiding splashing and waste. Furthermore, the nut on the upper screw can be placed in the guide groove, ensuring that there are no protruding parts on the upper surface of the splicing wheel. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0031] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 4 As shown, hollow fiber membrane filaments of different specifications may require take-up rollers of different diameters for winding. Therefore, take-up rollers of fixed size cannot meet these diverse needs, resulting in manufacturers needing to prepare take-up rollers of various sizes, increasing production costs and equipment management difficulties. This embodiment presents an adjustable-size modular hollow fiber membrane filament take-up roller, which can meet diverse needs. The take-up roller includes a fixed roller 102 and a splicing roller 104.
[0032] The fixed wheel 102 is rotatably connected to the cleaning tank 101 via a central shaft 103. The cleaning tank 101 is filled with cleaning fluid, allowing for simultaneous cleaning during the hollow fiber membrane filament winding process. A limiting ring is provided at the connection between the central shaft 103 and the cleaning tank 101, and the central shaft 103 is also connected to the output shaft of the drive unit. The limiting ring fixes the winding wheel on the central shaft, preventing axial movement and ensuring the stability of the membrane filament winding process. The central shaft can drive the winding wheel to move laterally, ensuring even distribution of the membrane filaments and maintaining a relatively consistent filament length, thus reducing wasted filament length.
[0033] Preferably, the outer side of the combination plate 109 is provided with a guide groove 110, which will carry the cleaning liquid in the cleaning tank when the take-up wheel starts to rotate. The guide groove 110 on the combination plate 109 can make the carried cleaning liquid flow back into the cleaning tank, avoiding splashing and waste of the cleaning liquid.
[0034] The splicing wheel 104 is composed of multiple arc-shaped combination plates 109 connected in sequence. There are various types of splicing wheels 104, each with a different diameter. However, the size and curvature of the combination plates 109 that make up splicing wheels 104 of the same size are the same.
[0035] Therefore, by using combination plates 109 with different curvature dimensions, splicing wheels 104 of different diameters can be formed. This allows for easy adjustment of the overall size of the entire take-up wheel, meeting the winding requirements of hollow fiber membrane filaments of different specifications and improving production efficiency.
[0036] In addition, the splicing wheel 104 is fixedly connected to the fixed wheel 102, and there is a gap between the splicing wheel 104 and the fixed wheel 102. Several connectors 105 are also provided in the gap between the splicing wheel 104 and the fixed wheel 102, and the upper and lower ends of the connectors 105 are detachably connected to the splicing wheel 104 and the fixed wheel 102, respectively.
[0037] The second aspect of this utility model is as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when a take-up wheel is partially damaged, due to the limitations of its overall structure, the entire take-up wheel often needs to be replaced, resulting in a waste of resources. Therefore, this embodiment not only provides a take-up splicing wheel 104 composed of multiple combination plates 109, but also ensures that each combination plate 109 is individually connected to the fixed wheel 102, thus allowing for individual replacement.
[0038] Specifically, the fixed wheel 102 includes a cylindrical wheel disc 106 and protruding edges 107 fixedly connected to the two sides of the wheel disc 106. The outer edge of the protruding edge 107 is provided with several connecting grooves 108. The outer side of the combined plate 109 is provided with a guide groove 110, and the upper and lower groove edges of the guide groove 110 are respectively provided with a wire hanging groove 112 and a screw hole 111.
[0039] The connector 105 includes a sleeve 113 and a lower screw 114 and an upper screw 115 threaded into the sleeve 113. The lower screw 114 is threaded into the connecting groove 108 on the fixed wheel 102, and the upper screw 115 is threaded into the screw hole 111 on the combination plate 109. The lengths of the lower screw 114 and the upper screw 115 are the same as the length of the sleeve 113, and a washer and a nut are also fitted onto the lower screw 114.
[0040] When a splicing unit (combination plate 109) of the splicing wheel 104 is damaged, only that splicing unit needs to be replaced; there is no need to replace the entire splicing wheel 104, let alone the entire take-up wheel. This greatly reduces maintenance costs and resource waste.
[0041] Furthermore, the connector 105 is composed of a sleeve 113 in conjunction with a lower screw 114 and an upper screw 115, allowing the length of the connector 105 to be adjusted. This enables it to adapt to splicing wheels 104 of various diameters. The fixed wheel 102 is provided with a connecting groove 108, and the splicing wheel 104 is provided with a screw hole 111 for threaded connection with the lower screw 114 and the upper screw 115, ensuring the overall stability of the take-up wheel.
[0042] In summary, this invention uses a splicing wheel 104, composed of multiple combination plates 109, to act as a take-up reel. Therefore, by using combination plates 109 with different curvature dimensions, splicing wheels 104 of different diameters can be formed. This allows for easy adjustment of the overall size of the take-up reel, meeting the take-up requirements of hollow fiber membrane filaments of different specifications and improving production efficiency. Furthermore, the splicing wheel 104 used for take-up employs a splicing structure. Therefore, when a splicing unit (combination plate 109) of the splicing wheel 104 is damaged, only that splicing unit needs to be replaced; there is no need to replace the entire splicing wheel 104, let alone the entire take-up reel. This significantly reduces maintenance costs and resource waste.
[0043] Additionally, the connector 105 can be composed of a sleeve 113 in conjunction with the lower screw 114 and the upper screw 115, allowing the length of the connector 105 to be adjusted. This enables it to adapt to splicing wheels 104 of various diameters. The fixed wheel 102 is provided with a connecting groove 108, and the splicing wheel 104 is provided with a screw hole 111 for threaded connection with the lower screw 114 and the upper screw 115, ensuring the overall stability of the take-up wheel. The outer side of the combination plate 109 is provided with a guide groove 110. When the take-up wheel starts to rotate, it will carry the cleaning fluid in the cleaning tank. The guide groove 110 on the combination plate 109 allows the carried cleaning fluid to flow back into the cleaning tank, avoiding splashing and waste of the cleaning fluid. Furthermore, the nut on the upper screw 115 can be placed in the guide groove 110, so that there are no protruding parts on the upper surface of the splicing wheel 104.

[0045] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
