Description

Technical Field

[0001] This invention belongs to the technical field of chemical fiber spinning equipment, and in particular relates to a heat-compensating modular spinning assembly insulation adapter. Background Technology

[0002] In the chemical fiber spinning process, the spinning assembly is a core component, and its installation dimensions (plate diameter) must precisely match the mounting holes on the spinning box. However, in actual production, due to customer order adjustments, product structure changes, or temporary production line reconfigurations, the demand for spinning assemblies with specific plate diameters often increases, while the available production lines are designed with larger plate diameters. In this case, directly installing the small-sized spinning assembly into the mounting holes of the large-sized box will cause a series of technical problems due to the annular gap between them.

[0003] To address the aforementioned size mismatch issue, there are two main existing solutions: one is to directly insert small-sized spinning components into the mounting holes of large-sized boxes; the other is to temporarily fill the gaps with materials such as insulation cotton.

[0004] The two existing solutions mentioned above still have the following obvious drawbacks in practical applications; 1. For direct installation, the large annular gap between the spinning assembly and the mounting holes in the housing leads to significant heat loss and uneven temperature distribution around the assembly, affecting the melt rheological properties. Simultaneously, because the outer diameter of the spinning assembly is much smaller than the inner diameter of the mounting holes in the housing, effective radial positioning cannot be achieved, making the assembly prone to skew during installation and difficult to precisely align with the material connector above. These combined issues result in unstable spinning process temperatures, a major cause of quality defects such as uneven yarn count and yarn breakage in the product. 2. While temporary filling with insulation cotton can partially improve the insulation effect, the filling material is loose and irregular, resulting in unstable insulation performance and the insulation effect cannot be reused accurately. It is also difficult to solve the problem of installation alignment. It is a temporary and ineffective expedient.

[0005] To address these issues, we provide a thermal compensation type modular spinning assembly insulation adapter. Summary of the Invention

[0006] The purpose of this invention is to provide a thermal compensation type modular spinning component insulation adapter. By setting a sleeve body with a phase change heat storage material chamber to fill the annular gap between the spinning component and the box mounting hole, and cooperating with a fastening mechanism to achieve a stable connection between the component and the sleeve, the size matching effect of the sleeve body solves the installation alignment difficulty, and at the same time solves the problems of poor insulation effect, uneven temperature field and product quality fluctuation caused by size mismatch.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention provides a heat-compensating modular spinning assembly insulation adapter, including a sleeve body, which is disposed in an annular gap between the spinning box mounting hole and the spinning assembly; wherein, the spinning box mounting hole is formed on the spinning box, the spinning assembly is installed in the spinning box mounting hole, and an annular gap is formed between the spinning box mounting hole and the spinning assembly. The sleeve body is also fixed with a fastening mechanism, which limits the position between the spinning assembly and the sleeve body; The sleeve body includes a fixed cylinder, and the side wall of the fixed cylinder has a set of annularly distributed arc-shaped chambers. Each arc-shaped chamber is a closed cavity, and the set of arc-shaped chambers are not connected to each other. The interior of each arc-shaped chamber is filled with a heat insulation layer, which is composed of phase change heat storage material.

[0008] Furthermore, the sleeve body only includes a fixed sleeve, forming an integral sleeve structure. The inner diameter of the fixed sleeve matches the outer diameter of the spinning assembly, and the outer diameter of the fixed sleeve matches the inner diameter of the mounting hole of the spinning box.

[0009] Furthermore, the sleeve body also includes an inner sleeve, forming a split sleeve structure. The inner sleeve is detachably connected to the inner side of the fixed sleeve, and a group of inner sleeves are detachably nested together in sequence. The inner diameter of the innermost inner sleeve matches the outer diameter of the spinning assembly, and the outer diameter of the fixed sleeve matches the inner diameter of the mounting hole of the spinning box.

[0010] Furthermore, the sleeve body also includes an outer sleeve, forming a split sleeve structure. The outer sleeve is detachably connected to the outside of the fixed sleeve, and a group of outer sleeves are detachably nested together in sequence. The outer diameter of the outermost outer sleeve matches the inner diameter of the mounting hole of the spinning box, and the inner diameter of the fixed sleeve matches the outer diameter of the spinning assembly.

[0011] Furthermore, the sleeve body also includes an inner sleeve and an outer sleeve, forming a split sleeve structure. The inner sleeve is detachably connected to the inner side of the fixed sleeve, and the outer sleeve is detachably connected to the outer side of the fixed sleeve. A set of inner tubes are detachably nested together, with the inner diameter of the innermost inner tube matching the outer diameter of the spinning assembly; A set of outer inserts are detachably nested together, with the outer diameter of the outermost insert matching the inner diameter of the mounting hole in the spinning box.

[0012] Furthermore, the fastening mechanism is a ring-shaped anti-loosening mechanism, and each ring of anti-loosening mechanisms can be detachably installed on the top of the sleeve body. The anti-loosening mechanisms extend from the top into the inner cavity of the sleeve body. An annular groove is provided at the top position of the circumference of the spinning assembly. The spinning assembly and the sleeve body are engaged and limited by the ring of anti-loosening mechanisms and the annular groove.

[0013] Furthermore, the anti-loosening mechanism includes a fixed seat plate and a movable seat plate, which are slidably connected.

[0014] Furthermore, the top plate of the fixed base plate is provided with connecting holes and movable grooves; Two symmetrically arranged rails are fixed to the bottom surface of the top plate of the fixed base plate, and through holes are opened on the side plate of the fixed base plate.

[0015] Furthermore, a lever is fixed at the center of the top surface of the movable seat plate, and the lever passes horizontally through the movable groove; Both sides of the top surface of the movable seat plate are fixed with rail grooves that match and connect with the rails; The upper and lower sides of the inner side of the movable seat plate are connected to the side plate of the fixed seat plate by springs. A locking block with a through hole is fixed in the center of the inner side of the movable seat plate. The locking block is used to lock into the annular groove of the spinning assembly.

[0016] Furthermore, the fastening mechanism consists of a ring of threaded set screws, and a ring of radially transverse threaded locking holes is provided on the side wall of the sleeve body. The threaded set screws are respectively connected to the corresponding threaded locking holes, and the front end of the threaded set screw can press against the outer wall of the spinning assembly.

[0017] The present invention has the following beneficial effects: 1. This invention uses a sleeve body with an inner diameter adapted to the spinning assembly and an outer diameter adapted to the mounting holes of the housing to solidly fill the annular gap between the two, transforming the air insulation layer into a solid metal filling, which greatly reduces heat convection and heat radiation loss. At the same time, by matching the outer diameter of the sleeve body with the inner diameter of the mounting holes of the housing, the sleeve body can be directly embedded into the mounting holes of the housing, restricting the radial displacement of the spinning assembly and achieving precise alignment. This solves the two core pain points of the prior art: "difficult installation alignment" and "poor heat preservation effect".

[0018] 2. The core improvement of this invention lies in the fact that a set of annularly distributed arc-shaped chambers are provided inside the side wall of the fixed cylinder. Each chamber is filled with a phase change heat storage material. This material can absorb or release a large amount of latent heat through its own phase change process (such as solid-liquid transition) within the normal operating temperature range of the spinning assembly: when the temperature is too high, the phase change material melts and absorbs heat, suppressing the temperature rise; when the temperature is too low, the phase change material solidifies and releases heat, compensating for heat loss. This makes the device no longer a passive heat insulation body, but a "heat compensation" device with active thermal regulation capability, which can significantly improve the uniformity and stability of the temperature field around the spinning assembly, fundamentally ensuring the stability of the spinning process temperature.

[0019] 3. This invention, by setting up an inner sleeve and an outer sleeve, forms a split sleeve structure. In the face of different size mismatches, operators can quickly assemble the required matching sleeve by selecting different numbers and specifications of inner and outer sleeves, just like "building blocks". This modular design allows the factory to produce only one set of standardized kits to adapt to the matching requirements of various spinning components and box installation positions of different specifications, which greatly improves the versatility and reusability of tooling, reduces spare parts inventory costs, and realizes flexible production scheduling.

[0020] 4. This invention provides two fastening mechanism solutions. The first is a top-locking anti-loosening mechanism, where a lever controls the extension and retraction of the locking block, and spring force automatically engages it in the annular groove at the top of the spinning assembly, achieving quick and reliable locking. Disassembly is simple; just move the lever again to release the lock, making operation extremely convenient. The second is a radial set screw fastening mechanism, where tightening the threaded set screw secures it against the outer wall of the spinning assembly. This mechanism is simple in structure and low in manufacturing cost. Both solutions can be flexibly selected for different application scenarios, meeting varying fastening force requirements and cost considerations.

[0021] 5. This invention makes component installation faster and more precise, simplifying the operation for workers; at the same time, the stable heat preservation effect ensures the uniformity of the spinning process temperature, effectively avoiding quality defects such as uneven yarn and yarn breakage caused by temperature fluctuations, significantly improving production efficiency and product quality. Using the device of this invention, there is no need to modify the expensive spinning box or customize special-specification spinning components, which can realize the flexible use of components between different production lines, quickly respond to market demands, and has significant economic benefits.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: The present invention is a heat-compensating modular spinning assembly insulation adapter, which aims to solve the problems of installation alignment difficulties and deterioration of insulation performance when small-sized spinning assemblies are installed in the mounting position of large-sized boxes.

[0037] like Figure 1 , Figure 3 As shown, the device includes a sleeve body. In the application scenario, a spinning box is provided with a spinning box mounting hole 100, and the spinning assembly 200 is installed in the spinning box mounting hole 100. Since the outer diameter of the spinning assembly 200 is smaller than the inner diameter of the spinning box mounting hole 100, an annular gap 300 will be formed between the two. The sleeve body of the present invention is disposed in the annular gap 300.

[0038] In this embodiment, the sleeve body adopts an integrated structure. Specifically, the sleeve body includes only one fixing cylinder 410, forming an integrated sleeve structure. The fixing cylinder 410 is a cylindrical component, preferably made of aluminum alloy. Aluminum alloy has the advantages of good thermal conductivity, light weight, and easy machining, which is conducive to uniform heat transfer and overall lightweighting of the device. Its inner diameter is designed to match the outer diameter of the spinning assembly 200 to be installed (for example, in the scenario of installing a spinning assembly 200 with an outer diameter of 70 mm into a spinning box mounting hole 100 with an inner diameter of 95 mm, the inner diameter of the fixing cylinder 410 should be slightly larger than 70 mm to achieve fitting). Its outer diameter... It is designed to match the inner diameter of the mounting hole 100 of the target spinning box (correspondingly, the outer diameter of the fixing cylinder 410 should be slightly less than 95mm to facilitate installation). It should be clarified that 70mm and 95mm here are only examples to illustrate the specific meaning of "matching". The core technical solution of the present invention is not limited to this specific size combination, but is applicable to any size mismatch scenario caused by the outer diameter of the spinning assembly 200 being smaller than the inner diameter of the mounting hole 100 of the spinning box. In this way, the fixing cylinder 410 solidly fills the original annular gap 300, transforming the air insulation layer into a solid metal filling, which greatly reduces heat convection and heat radiation loss.

[0039] As a core improvement of this invention, such as Figure 8As shown, a set of annularly distributed arc-shaped chambers 411 are formed inside the side wall of the fixed cylinder 410. Each arc-shaped chamber 411 is a closed, independent cavity that is not interconnected with each other. These arc-shaped chambers 411 can be pre-reserved with open arc-shaped cavities during the casting of the fixed cylinder 410. Molten phase change material is poured through the openings, and the openings are welded closed after cooling to ensure the airtightness of the chambers. Inside each arc-shaped chamber 411, a heat insulation layer 412 is filled, and this heat insulation layer 412 is composed of phase change heat storage material. When filling the insulation layer 412, a volume expansion space is reserved (filling rate of 85%~95% of the chamber volume) to accommodate the volume expansion generated during the solid-liquid phase change of the phase change material, preventing the chamber from bursting. The specific type of phase change heat storage material should be selected according to the normal operating temperature of the spinning assembly 200 to ensure that a reversible solid-liquid phase change occurs within this temperature range. For example, when the spinning assembly 200 is used in polyester spinning, its operating temperature is approximately 280℃~300℃, and a metal-based phase change material (such as aluminum-based alloy) or a molten salt phase change material (such as sodium chloride-potassium chloride eutectic salt) with a phase change temperature in the range of 280℃~300℃ can be selected; when the spinning assembly 200 is used in polypropylene or nylon spinning, its operating temperature is approximately 200℃~250℃, and an organic phase change material with a phase change temperature matching that can be selected. (e.g., erythritol) or low-melting-point alloys. Those skilled in the art can select a phase change heat storage material with a suitable phase change temperature through conventional experiments based on the actual spinning process temperature. The phase change heat storage material can absorb or release a large amount of latent heat through its own phase change process (e.g., solid-liquid transition) within the normal operating temperature range of the spinning assembly 200. When the operating temperature of the spinning assembly 200 fluctuates, such as due to instantaneous changes in melt flow rate or environmental interference causing local overheating, the phase change material in the insulation layer 412 will melt and absorb heat to suppress the temperature rise. Conversely, when the temperature is too low, the phase change material will solidify and release heat to compensate for the heat loss. This design makes the device no longer a passive heat insulation body, but a "heat compensation" device with active thermal regulation capability, which can significantly improve the uniformity and stability of the temperature field around the spinning assembly 200.

[0040] In addition, a fastening mechanism is fixed on the sleeve body. The spinning assembly 200 and the sleeve body are limited and fixed by the fastening mechanism. In this embodiment, for example... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the fastening mechanism is specifically a ring of anti-loosening mechanisms 500A. All anti-loosening mechanisms 500A are fixed to the top of the sleeve body and can extend into the inner cavity of the sleeve body from the top. Correspondingly, a ring of annular grooves is pre-opened at the top of the circumference of the spinning assembly 200. When the bottom of the spinning assembly 200 contacts the bottom surface of the inner cavity of the sleeve body, the spinning assembly 200 is installed in place. At this time, its annular groove and the locking block 524 of the anti-loosening mechanism 500A are at the same horizontal position, ensuring that the locking block 524 can be accurately locked in. During assembly, by operating the anti-loosening mechanism 500A, it is locked into the annular groove, thereby realizing the locking and limiting between the spinning assembly 200 and the sleeve body.

[0041] Furthermore, such as Figure 9 , Figure 10 As shown, each anti-loosening mechanism 500A specifically includes a fixed base plate 510 and a movable base plate 520, which are slidably connected. The top plate of the fixed base plate 510 has a connecting hole 511 and a movable groove 512. The connecting hole 511 is fixedly connected to a threaded hole on the top of the sleeve body by a fastener (such as a screw), thus fixing the anti-loosening mechanism 500A to the sleeve body. Two symmetrically arranged rails 513 are fixed to the bottom surface of the top plate of the fixed base plate 510, and a through hole 514 for the locking block 524 to pass through is opened on its side plate. A lever 522 is fixed to the center of the top surface of the movable base plate 520. This lever 522 passes upward through the movable groove 512, facilitating manual operation by the operator. The two sides of the top surface of the movable base plate 520 are fixed... The guide groove 523 is matched and connected to the guide rail 513 to ensure smooth and precise sliding. The upper and lower sides of the inner side of the movable seat plate 520 are connected to the side plate of the fixed seat plate 510 through springs 521. A locking block 524 is fixed in the center of the inner side, facing the through hole 514. Under normal conditions, under the pushing force of the spring 521, the locking block 524 passes through the through hole 514 and remains in an inwardly extended state. During assembly, the operator can push the lever 522 backward and outward to overcome the spring force and retract the locking block 524. After the spinning assembly 200 is placed in place, the lever 522 is released, and the locking block 524 automatically locks into the annular groove of the spinning assembly 200 under the action of the spring force, realizing fast and reliable locking. When disassembly is required, the lever 522 can be pushed again to release the lock.

[0042] Example 2: Based on Example 1, this example further expands the structure of the sleeve body, making it modular and size-adaptable, and can adapt to the matching requirements of various specifications of spinning components 200 and box mounting positions.

[0043] The main difference between this embodiment and Embodiment 1 lies in the structure of the sleeve body, such as... Figure 4As shown, the sleeve body includes a fixed sleeve 410 and an inner sleeve 420, forming a split sleeve structure. The inner sleeve 420 is detachably connected to the inner side of the fixed sleeve 410. When it is necessary to adapt to a smaller spinning assembly 200, an appropriate number of inner sleeves 420 can be selected (i.e., one or more can be used). If multiple inner sleeves 420 are selected, a group of inner sleeves 420 can be detachably nested and connected in sequence. Finally, the inner diameter of the innermost inner sleeve 420 matches the outer diameter of the target spinning assembly 200, while the outer diameter of the fixed sleeve 410 remains unchanged and still matches the inner diameter of the spinning box mounting hole 100.

[0044] In addition, such as Figure 5 As shown, as another option, in addition to the fixed sleeve 410, the sleeve body may also include an outer sleeve 430 to form another split sleeve structure. The outer sleeve 430 is detachably connected to the outside of the fixed sleeve 410. When in use, an appropriate number of outer sleeves 430 can be selected according to the usage requirements (i.e., one or more can be used). If multiple outer sleeves 430 are selected, a group of outer sleeves 430 can be detachably nested and connected in sequence. Finally, the outer diameter of the outermost outer sleeve 430 matches the inner diameter of the spinning box mounting hole 100, while the inner diameter of the fixed sleeve 410 remains unchanged and still matches the outer diameter of the spinning assembly 200.

[0045] Of course, such as Figure 2 As shown, in more complex and general scenarios, the sleeve body, in addition to the fixed sleeve 410, can also include an inner sleeve 420 and an outer sleeve 430, forming a more comprehensive split sleeve structure. When in use, an appropriate number of inner sleeves 420 and outer sleeves 430 can be selected according to the usage requirements (i.e., one or more inner sleeves 420 and one or more outer sleeves 430). If multiple inner sleeves 420 are selected, a set of inner sleeves 420 are nested in sequence inside the fixed sleeve 410, and the inner diameter of the innermost inner sleeve 420 is adapted to the spinning assembly 200. If multiple outer sleeves 430 are selected, a set of outer sleeves 430 are nested in sequence outside the fixed sleeve 410, and the outer diameter of the outermost outer sleeve 430 is adapted to the spinning box mounting hole 100.

[0046] When the fixed cylinder 410 is nested with the inner cylinder 420 and the outer cylinder 430, in order to reduce heat loss at the contact surfaces between the cylinders and improve the overall heat conduction efficiency, a thermally conductive medium is coated between the mating cylinder walls. This thermally conductive medium is preferably thermally conductive adhesive or thermally conductive silicone grease, which can effectively fill the tiny gaps at the contact surfaces, eliminate interfacial thermal resistance, and ensure that heat is smoothly transferred between the cylinders, thereby maintaining the overall temperature uniformity of the sleeve body. This optimization measure also applies to all contact interfaces between the fixed cylinder 410 and the inner cylinder 420, between the inner cylinders 420, between the fixed cylinder 410 and the outer cylinder 430, and between the outer cylinders 430.

[0047] When the fixed cylinder 410 is nested with the inner cylinder 420 and the outer cylinder 430, in order to reduce heat loss at the contact surfaces between the cylinders and improve the overall heat conduction efficiency, a thermally conductive medium is coated between the mating cylinder walls. This thermally conductive medium is preferably thermally conductive adhesive or thermally conductive silicone grease, which can effectively fill the tiny gaps at the contact surfaces, eliminate interfacial thermal resistance, and ensure that heat is smoothly transferred between the cylinders, thereby maintaining the overall temperature uniformity of the sleeve body. This optimization measure also applies to all contact interfaces between the fixed cylinder 410 and the inner cylinder 420, between the inner cylinders 420, between the fixed cylinder 410 and the outer cylinder 430, and between the outer cylinders 430.

[0048] In addition, the inner sleeve 420 and the fixed sleeve 410, the outer sleeve 430 and the fixed sleeve 410, each inner sleeve 420, and each outer sleeve 430 can be axially limited by threaded connection or end face retainer to prevent relative movement or rotation of each sleeve during use, while maintaining detachability.

[0049] This modular design allows the factory to produce only one standardized kit containing a fixed sleeve 410 and inner sleeves 420 and outer sleeves 430 of different sizes. In the face of different size mismatches, operators can quickly assemble the required matching sleeves like "building blocks", which greatly improves the versatility and reusability of tooling and reduces spare parts inventory costs.

[0050] Example 3 provides another implementation of the fastening mechanism as an alternative to the anti-loosening mechanism 500A in Example 1.

[0051] In this embodiment, as Figure 7As shown, the fastening mechanism consists of a ring of threaded set screws 500B. Correspondingly, a ring of radially transverse threaded locking holes is provided on the side wall of the sleeve body (whether it is the integrated sleeve structure in Embodiment 1 or the split sleeve structure in Embodiment 2). Each threaded set screw 500B is threaded into a corresponding threaded locking hole. After the spinning assembly 200 is placed into the inner cavity of the sleeve body and adjusted to the appropriate position, the operator uses a tool (such as an Allen wrench) to tighten each threaded set screw 500B, so that the front end of the threaded set screw 500B tightly abuts against the outer wall of the inner spinning assembly 200, thereby fixing the two into a whole through radial tightening force. This solution has a simpler structure and lower manufacturing cost, and is especially suitable for application scenarios where the fastening force requirement is not particularly high or the component size is relatively standard.

[0052] In summary, the present invention provides a heat-compensating modular spinning assembly insulation adapter, which solves two major technical problems in chemical fiber spinning production: installation difficulties and uneven insulation caused by the mismatch between the component and the housing size. This is achieved by setting a sleeve body with a phase change heat storage material chamber, and combining it with an integrated or modular split structure, as well as a top-clamping or radial top-thread fastening mechanism. Its ingenious structural design, comprehensive functions, high flexibility and reusability have significant economic benefits and industrial practical value.
