Description

Technical Field

[0001] This utility model belongs to the technical field of wet spinning equipment, and in particular relates to a wet spinning take-up roller, a wet spinning take-up mold, and a melting and pressing mold. Background Technology

[0002] In the wet spinning process of polymer optical fiber panels, the orderly collection and stable fixation of the fiber bundles are key steps to ensure the quality of subsequent melting and pressing.

[0003] In existing technologies, take-up rollers mostly adopt an integral circular structure, which has the following drawbacks: First, the filaments wound on the circular roller are prone to slipping and scattering, making them difficult to manage; second, the integral structure is inconvenient to disassemble and assemble, and residual solvents and impurities on the surface are difficult to clean thoroughly, easily causing cross-contamination between batches; third, it cannot adapt to polymer optical fibers of different filament types (such as round filaments and square filaments) or diameters, resulting in poor adaptability. Furthermore, traditional take-up dies are mostly fixed-angle structures, unable to adjust the side plate angle according to the filament arrangement requirements, and the filaments need to be transferred to a separate fusion pressing die after cutting, which can easily lead to filament displacement and skewing, affecting the subsequent fusion splicing quality. Utility Model Content

[0004] The main objective of this invention is to provide a wet spinning take-up roller, a wet spinning take-up mold, and a melting and pressing mold. The technical problem to be solved is how to provide a wet spinning take-up roller, a wet spinning take-up mold, and a melting and pressing mold that allows for convenient assembly and disassembly of the take-up roller, ensuring thorough cleaning without dead corners and preventing cross-contamination between batches. It also adapts to the collection needs of polymer optical fibers with different filament types and diameters. The take-up mold's side plate angle is adjustable to accommodate filament arrangement requirements, and the cutter positioning groove at the top of the side plate allows the cutter and take-up mold to directly combine to form a six-sided closed melting and pressing mold, enabling melting and pressing without transferring the filament bundle, thus avoiding filament bundle displacement and skewing that affects the splicing quality. Furthermore, the synergistic structure of the three components eliminates the need for a secondary filament bundle transfer process, improving processing efficiency and ensuring the orderly arrangement of polymer optical fibers during collection, fixing, cutting, and melting and pressing. This, in turn, ensures the light transmittance and structural integrity of the subsequent polymer optical fiber panel, making it particularly suitable for polymer optical fiber collection and subsequent melting and pressing, thus enhancing its practicality.

[0005] The objective of this utility model and the technical problem it solves are achieved through the following technical solution. A wet spinning take-up roller according to this utility model comprises:

[0006] Roller shaft;

[0007] Two baffles, identical in size and shape, are arranged parallel to each other at both ends of the roller shaft; the two baffles are fixedly connected to the roller shaft and can rotate with the roller shaft; the baffles and the roller shaft form a support assembly.

[0008] Multiple wet spinning take-up dies are detachably mounted on the support assembly; the open ends of adjacent wet spinning take-up dies are adjacent to each other to form a yarn winding channel.

[0012] Preferably, in the aforementioned wet spinning take-up roller, at least one wet spinning take-up die is provided on each bearing plane.

[0013] The objective of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a wet spinning take-up die is provided, which is used to carry and fix polymer optical fiber filaments. Its structure includes:

[0014] The base plate is flat; the base plate is provided with a connecting structure so that it can be detachably connected to the aforementioned support assembly of the wet spinning take-up roller;

[0015] Two side plates are disposed on the bottom plate; the two side plates and the bottom plate form a frame-shaped cavity for accommodating polymer optical fiber filaments, so that the polymer optical fiber filaments can be arranged in an orderly manner in the frame-shaped cavity with their axes perpendicular to the two side openings of the frame-shaped cavity;

[0016] The cover plate is detachably mounted on the top of the side plate; the size of the cover plate is adapted to the top opening size of the frame-shaped mold cavity; after the polymer optical fiber filaments fill the frame-shaped mold cavity, the cover plate can close to press and fix the polymer optical fiber filaments inside the frame-shaped mold cavity, thereby realizing the binding of polymer optical fiber filaments.

[0017] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0018] Preferably, in the aforementioned wet spinning take-up die, the included angle between the side plate and the bottom plate is adjustable.

[0019] Preferably, in the aforementioned wet spinning take-up die, both side plates are perpendicular to the base plate and arranged parallel to each other on the base plate; and / or, the cover plate is flat.

[0020] Preferably, in the aforementioned wet spinning take-up die, the top of the side plate is provided with cutter positioning grooves at both ends near the opening of the frame-shaped mold cavity, for cutting and positioning polymer optical fiber filaments.

[0021] Preferably, in the aforementioned wet spinning take-up die, a handle is provided on the side plate on the outside of the frame-shaped die cavity.

[0022] The objective of this utility model and the technical problem it solves are achieved through the following technical solution. A melting and pressing mold according to this utility model includes:

[0023] A wet spinning take-up die according to the aforementioned method;

[0024] Two cutting blades, each comprising two oppositely arranged blade handles; the cross-sectional shape of the cutting blade positioning groove is adapted to the shape of the blade handle, used to position the cutting blade when cutting polymer optical fiber filaments; during cutting, the cutting edges of the two cutting blades face the base plate, and the blade handles are inserted into the corresponding cutting blade positioning grooves to engage, thus fixing the cutting blades in place; the cutting blades, the base plate, the two side plates, and the cover plate together form a six-sided closed melting and pressing mold.

[0025] By employing the above technical solutions, the wet spinning take-up roller, wet spinning take-up die, and melting and pressing die proposed in this utility model have at least the following advantages:

[0026] The wet spinning take-up roller proposed in this utility model adopts a support assembly composed of regular polygonal baffles and roller shafts. The flat sides of the regular polygons can form a stable bearing plane, and each bearing plane can be detachably installed with a take-up die. This structural design allows the installation and disassembly of the die to be completed without the need for complex tools, using only simple connection methods such as bolts and clips, which greatly improves the convenience of assembly and disassembly. On the other hand, the detachable modular die can be removed from the roller individually for offline cleaning, completely eliminating the sanitary dead corners on the surface of the traditional integral circular roller, and effectively avoiding solvent residue and cross-contamination between batches. At the same time, by changing the take-up die with different cavity sizes, or by selecting regular polygonal baffles with different numbers of sides such as squares to adjust the number of bearing planes, it can flexibly adapt to the needs of polymer optical fibers with different diameters and take-up amounts, significantly improving the flexibility of the equipment.

[0027] The wet spinning take-up die proposed in this utility model has an adjustable angle between its side plate and bottom plate according to the characteristics of the filament bundle. When processing filament bundles with different cross-sectional shapes such as round and square filaments, changing the side plate at different angles allows the frame-shaped die cavity to better fit the filament bundle arrangement requirements, avoiding the filament bundle skewing problem caused by traditional fixed-angle dies. At the same time, the cover plate size is precisely matched with the top opening of the die cavity. After the filament bundle fills the die cavity, closing the cover plate can directly press and fix the filament bundle. Combined with the precise limitation of the cutting position by the cutting blade positioning groove on the top of the side plate, it can ensure that the filament bundle always maintains an orderly state with parallel axes during the fixing and cutting process, fundamentally avoiding the displacement and deformation problems that are prone to occur when transferring the filament bundle.

[0028] The fusion pressing mold proposed in this utility model is based directly on the wet spinning take-up mold. It forms a six-sided closed structure by engaging the cutter with the cutter positioning groove on the mold side plate. This integrated design eliminates the secondary operation of transferring the fiber bundle from the take-up mold to a separate fusion pressing mold after cutting in the traditional process. This not only reduces process time and improves processing efficiency, but more importantly, the fiber bundle can directly enter the fusion pressing stage without leaving the original mold cavity. This can maintain the orderly arrangement accuracy of the fiber bundle to the greatest extent and avoid the impact of fiber bundle misalignment on the subsequent fusion quality during the transfer process. Finally, through the orderly take-up of the take-up roller, the stable fixation of the take-up mold, and the precise fusion of the fusion pressing mold, the three work together to ensure the regular arrangement of the polymer optical fiber in the whole process, providing reliable support for the uniformity of light transmission performance and structural integrity of the subsequent polymer optical fiber panel.

The cover plates and the side plates are connected by a detachable hinge structure. During the winding process, the cover plates are in the unfolded state and are located in the same plane as the side plates so as not to hinder the winding operation. After the strands fill the cavity, the two cover plates close towards the center of the cavity along the top of the side plates. After the two cover plates are closed, their size matches the size of the top opening of the cavity, pressing and fixing the strands inside the cavity to achieve the bundling of polymer optical fiber strands. The top of the side plates is provided with cutter positioning grooves 321 near the two side openings of the frame-shaped cavity, that is, at both ends along the strand axis, for precise positioning of the cutter when cutting polymer optical fiber strands. Handles 322 are provided on the outer side of the side plates for easy gripping when disassembling and assembling the winding mold.

[0042] In some specific embodiments of this utility model, the specific structure of the wet spinning take-up die is as follows: its base plate is an aluminum alloy plate with a width of 200mm (dimension along the roller axis), a length of 200mm (dimension along the winding channel), and a thickness of 5mm. Two protrusions (3mm high, 8mm diameter) are provided at the bottom, which are adapted to the pre-set grooves on the square side of the take-up roller baffle to achieve a detachable connection. The two side plates are aluminum alloy plates with a length of 200mm, a height of 200mm, and a thickness of 5mm. They are arranged perpendicular to the base plate and parallel to each other by default (the angle between the base plate and the side plates is 90°). They are fixed to the base plate through slots, forming a shape with a length of 200mm, a width of 200mm, and a height of 200mm. The mold cavity is 0mm thick; a U-shaped handle (made of stainless steel, with an opening width of 30mm and a length of 100mm) is welded to the middle of the outer side of the side plate (the side away from the mold cavity) for easy mold assembly and disassembly; U-shaped cutter positioning grooves are provided at both ends of the top of the side plate near the opening of the mold cavity, with a groove depth of 10mm and a groove width of 8mm, for positioning the cutter during cutting; the cover plate is a transparent acrylic plate with a length of 200mm, a width of 100mm and a thickness of 5mm, which is connected to the top of the side plate by a detachable hinge. After the mold cavity is filled with polymer optical fiber strands (0.5mm in diameter, with the strand axis arranged parallel to the direction perpendicular to the opening of the mold cavity), the cover plate closes to press the strands together and prevent the strands from loosening.

Figure 3 and attached Figure 4 As shown, it consists of the aforementioned wet spinning take-up mold and two cutters 34; each cutter includes two oppositely arranged handles 341, the shape of which is adapted to the cutter positioning groove; during cutting, the cutter blade moves downward toward the base plate, and the handle is inserted into the positioning groove and locked in place. At this time, the blade contacts the base plate, and the cutter, base plate, side plate, and cover plate together form a six-sided closed structure, which can be directly used for melting and pressing without transferring the yarn bundle.

[0044] In some specific embodiments of this utility model, the specific structure of the melting and pressing mold is as follows: The wet spinning and take-up mold of the aforementioned embodiment is used, and the frame-shaped mold cavity is filled with orderly arranged polymer optical fiber strands (the distance between opposite sides of the strand is 200mm); the two cutters are made of stainless steel, with a blade length of 200mm (matching the width of the frame-shaped mold cavity), and the handle is rectangular (section 8mm×10mm, adapted to the U-shaped positioning groove). The handle length (50mm) matches the thickness of the side plate, so that both ends of the handle slightly extend beyond the surface of the side plate to facilitate the disassembly and operation of the melting and pressing mold; for the polymer optical fiber strands... During cutting, the blades of the two cutters are positioned with their cutting edges facing the base plate, and the handles are inserted into the U-shaped positioning grooves on the top of the side plates until the bottom of the blades is in contact with the surface of the base plate. The cutters are then secured by the positioning grooves. At this point, the cutters, the base plate, the two side plates, and the cover plate together form a six-sided closed fusion molding die with a length of 200mm, a width of 200mm, and a height of 200mm. The fusion molding die, along with the internal fiber bundles, is placed in a vacuum oven, and an 8kg counterweight is placed on the cover plate. The oven is then heated at 130℃ and a vacuum of 10kPa for 4 hours to achieve tight fusion of the polymer optical fiber fibers, resulting in a panel blank.
