Description

Technical Field

[0001] The invention relates to the technical field of novel polyester fibers, in particular to a novel polyester fiber and a preparation device thereof. Background Art

[0002] As a synthetic fiber widely used in many fields such as textiles and industrial materials, the performance and quality of polyester fiber play a key role in the quality of the final product.

[0003] In the actual production process, enterprises are often faced with the situation of producing various specifications of polyester fibers according to different order requirements. The adjustment of production process parameters of polyester fibers of different specifications, esterification reaction temperature, polycondensation reaction time and pressure, etc., will lead to great differences in the macroscopic properties of the fibers such as thickness, elasticity, and hardness.

[0004] However, most existing winding equipment usually uses springs to adjust the tension during winding. However, since the spring stiffness coefficient is fixed, it cannot be adjusted in real time according to the elastic properties of the fiber during the winding process. The initial force required for movement is limited in the production of fibers with large elastic differences due to the limited adjustment range of the tension, resulting in unstable quality of the package. In subsequent processing and use, fiber deformation, wrinkling and other problems are likely to occur, affecting production efficiency and product quality, and limiting the company's ability to respond to market demand.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0025] Embodiment 1 The present invention provides a technical solution: See also Figure 1-8 A novel polyester fiber preparation device comprises a mounting frame 1, a pay-off frame 2, a take-up frame 3 and a tension adjustment assembly arranged on the mounting frame 1, wherein the tension adjustment assembly comprises a tension adjustment frame 4, a horizontally arranged slide groove 42 is provided in the tension adjustment frame 4, a slider 43 is slidably connected to the middle of the slide groove 42, and two adjustment plates 44 are slidably connected to both sides of the slide groove 42; A bidirectional screw rod 5 is rotatably connected to the tension adjustment frame 4, and two sides of the bidirectional screw rod 5 are respectively threadedly connected to two adjustment plates 44; A tension spring 45 is provided between the slider 43 and the two adjustment plates 44, and two ends of the tension spring 45 are respectively against the slider 43 and the adjustment plates 44; The transfer roller 41 is rotatably connected to the front side of the slider 43 and is used to adjust the force required for the transfer roller 41 to move after compressing or stretching the tension spring 45 .

[0026] When the novel polyester fiber preparation device is in operation, the polyester fiber is released from the pay-off frame 2, the tension is adjusted by the transfer roller 41 on the tension adjustment frame 4, and finally the winding is completed by the take-up frame 3.

[0027] When the tension of the polyester fiber needs to be adjusted, the operator rotates the bidirectional screw 5 , the threads at both ends of the bidirectional screw 5 have opposite rotation directions, and the bidirectional screw 5 rotates in the tension adjustment frame 4 .

[0028] Since the threads at both ends of the bidirectional screw rod 5 are respectively connected to the two adjustment plates 44 , when the bidirectional screw rod 5 rotates, the two adjustment plates 44 are driven to move relative to or away from each other along the slide groove 42 .

[0029] When the bidirectional screw rod 5 is rotated clockwise, the two adjustment plates 44 will move closer to the middle; when it is rotated counterclockwise, the two adjustment plates 44 will move apart to both sides.

[0030] The movement of the adjusting plate 44 changes the distance between the adjusting plate 44 and the transfer roller 41 , thereby causing the tensioning spring 45 to undergo a stretching or compressing deformation.

[0031] When the adjustment plate 44 moves away from the transfer roller 41, the tension spring 45 is stretched; When the adjustment plate 44 moves toward the switching roller 41 , the tension spring 45 is compressed.

[0032] The deformation of the tensioning spring 45 will cause the transfer roller 41 to be subjected to forces of different magnitudes, and the pressure applied by the transfer roller 41 to the polyester fiber will also change accordingly, thereby achieving the adjustment of the tensioning degree of the polyester fiber.

[0033] When the tension spring 45 is stretched, the pressure of the transfer roller 41 on the fiber increases, and the tension of the fiber also increases accordingly; conversely, the tension decreases, and when increasing or decreasing, it still has the function of adaptively adjusting the tension.

[0034] By precisely adjusting the bidirectional screw 5, the deformation degree of the tensioning spring 45 can be accurately controlled, so that the polyester fiber maintains a stable tension during the winding process.

[0035] Stable tension helps to ensure uniform fiber thickness and stable structure, avoid problems such as uneven fiber thickness and strength caused by fluctuations in tension, and improve the overall quality of the new polyester fiber.

[0036] For polyester fibers with different thickness, elasticity, hardness and other characteristics prepared by different raw material formulas and production process parameters, the operator can adjust the appropriate tensioning degree by adjusting the bidirectional screw 5 at any time according to the actual production situation, so that the equipment can adapt to diverse production needs and further improve product quality.

[0037] Moreover, the adjustment process does not require complicated operations and replacement of a large number of equipment parts. This flexible tension adjustment method enables the equipment to quickly adapt to different order requirements and changes in equipment operating conditions, thereby improving the versatility of the equipment and its adaptability to the production environment.

[0038] The tensioning frame 4 further comprises a limiting component, which comprises a connecting column 51 arranged on one side of the tensioning frame 4, one end of the bidirectional screw 5 passes through the tensioning frame 4 and is fixedly connected to the connecting column 51, a ratchet 52 is arranged on the outer side of the connecting column 51, and a mounting column 53 is arranged on one side of the tensioning frame 4, and a ratchet 54 meshing with the ratchet 52 is rotatably connected to the mounting column 53; The pawl 54 is provided with a toggle protrusion, which protrudes from the front of the tension adjustment frame 4, and a locking spring 55 is provided between the mounting column 53 and the pawl 54; It also includes a turning handle 56, which includes a connecting piece and a turning handle. One end of the connecting piece is fixedly connected to the connecting column 51, and the other end is rotatably connected to the turning handle.

[0039] When the turning handle 56 is rotated in the forward direction to adjust the tension, the connecting column 51 drives the ratchet wheel 52 to rotate in the forward direction.

[0040] At this time, the pawl 54 slides on the back of the teeth of the ratchet 52. Due to the inclination angle, the pawl 54 rises along the tooth direction of the ratchet 52, so that the pawl 54 can smoothly pass over the teeth of the ratchet 52 and will not hinder the forward rotation of the ratchet 52 and the bidirectional screw 5. When the rotation is completed, the pawl 54 will quickly get stuck in the next tooth groove of the ratchet 52 under the action of gravity to complete the positioning.

[0041] If it is necessary to adjust the tension degree in the reverse direction or perform maintenance operations on the equipment, the operator can push the push protrusion on the pawl 54 protruding from the front of the tension adjustment frame 4 to overcome the elastic force of the locking spring 55 and separate the pawl 54 from the ratchet 52.

[0042] At this time, the ratchet wheel 52 can rotate freely in the reverse direction, and the bidirectional screw rod 5 can also rotate in the reverse direction, thereby achieving the purpose of adjusting the tensioning degree in the reverse direction.

[0043] The one-way locking function of the ratchet 52 and pawl 54 mechanism effectively prevents the bidirectional screw 5 from rotating in the opposite direction due to external factors after the tension is adjusted, thereby ensuring that the adjusted tension can be stably maintained, avoiding polyester fiber winding quality problems caused by unstable tension, loose fibers, and uneven thickness, thereby improving the consistency of product quality.

[0044] When adjusting the tension in the positive direction, the pawl 54 can smoothly pass over the teeth of the ratchet 52 without hindering the adjustment operation, making the tension adjustment process smooth and efficient. When adjusting the tension in the reverse direction, the pawl 54 can be easily separated from the ratchet 52 by turning the protrusion, so as to perform reverse adjustment or maintenance operations. This design ensures the stability of the tension adjustment while taking into account the flexibility of operation.

[0045] The matching mode of the ratchet 52 and the pawl 54 has been verified by long-term practice and has high reliability and durability. It can work stably for a long time in a complex production environment, reduces the failure rate of the equipment, and improves the overall reliability of the equipment.

[0046] The bidirectional screw rod 5 is divided into a first bidirectional threaded rod 57 and a second bidirectional threaded rod 58. The tension adjustment frame 4 is provided with a connecting groove 46, and the connecting groove 46 is located between the slide grooves 42; It also includes a separation component, which includes a connecting sleeve 6 slidably connected in the connecting groove 46, with a connecting hole 61 opened in the connecting sleeve 6, and the first two-way threaded rod 57 and the second two-way threaded rod 58 are both provided with a connecting protrusion 62 adapted to the connecting hole 61; a connecting spring 63 is provided between the connecting sleeve 6 and one of the connecting protrusions 62.

[0047] When it is necessary to adjust the tension of two different groups of fibers separately, the connecting sleeve 6 is slid in the connecting groove 46 through external operation, and moves in a direction away from one of the bidirectional threaded rods (assuming it is the first bidirectional threaded rod 57).

[0048] As the connecting sleeve 6 moves, the connecting sleeve 6 is gradually separated from the connecting protrusion 62 on the first bidirectional threaded rod 57 , while remaining connected to the connecting protrusion 62 on the second bidirectional threaded rod 58 .

[0049] At this time, the bidirectional screw rod 5 is rotated (at this time only the second bidirectional threaded rod 58 is effective), and the second bidirectional threaded rod 58 drives the adjustment plate 44 connected thereto to move along the corresponding slide groove 42, thereby stretching or compressing the tensioning spring 45 to adjust the tension of one group of fibers.

[0050] Since the first bidirectional threaded rod 57 is separated from the connecting sleeve 6, it will not rotate with the rotation of the bidirectional screw rod 5, and will not affect the tension of the other group of fibers, thereby achieving the function of adjusting the tension of two different groups of fibers separately.

[0051] When it is necessary to adjust the tension of the two groups of fibers synchronously, operate the connecting sleeve 6 to locate it in the middle position of the connecting groove 46, ensuring that the connecting hole 61 on the connecting sleeve 6 is adapted and connected with the connecting protrusion 62 on the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58 at the same time.

[0052] When the bidirectional screw rod 5 is rotated, the connecting sleeve 6 will slide in the connecting groove 46 along with the rotation of the screw rod, and at the same time drive the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58 to rotate synchronously.

[0053] The two bidirectional threaded rods respectively drive the corresponding adjustment plates 44 to move along the slide slot 42, and synchronously stretch or compress the tension spring 45, so as to achieve synchronous tension adjustment of the two groups of fibers.

[0054] During the synchronous adjustment process, the connecting spring 63 plays a role of buffering and fine adjustment.

[0055] Since there may be tiny errors and vibrations in the mechanical transmission process, the connecting spring 63 can absorb these energies to make the adjustment process smoother and avoid excessive or unstable adjustment of the tension due to instantaneous impact.

[0056] In actual production, companies may receive orders from different customers for polyester fibers with different properties.

[0057] The above-mentioned equipment can realize separate or synchronous adjustment of two groups of fibers through the connecting sleeve 6. Whether the two groups of fibers have exactly the same characteristics and need synchronous adjustment, or the two groups of fibers have large differences in characteristics and need separate adjustment, it can easily cope with it, greatly improving the adaptability of the equipment to diversified production needs.

[0058] Different raw material formulas and production process parameters will make polyester fibers have different properties such as thickness, elasticity, and hardness.

[0059] The equipment can flexibly select individual or synchronous adjustment methods for these fibers with different characteristics, providing the most appropriate tension adjustment for each group of fibers to ensure product quality.

[0060] The simultaneous adjustment function enables the operator to adjust the tension of two groups of fibers at once, which greatly reduces the adjustment time compared to adjusting each group of fibers separately.

[0061] This can significantly improve production efficiency and increase output per unit time in large-scale production.

[0062] For situations where frequent switching is required to produce fibers of different specifications, the equipment can quickly switch from synchronous adjustment mode to individual adjustment mode, and vice versa, reducing the downtime in the production process and improving the continuous production capacity of the equipment.

[0063] The buffering effect of the connecting spring 63 during the adjustment process ensures the stability of the connection between the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58, and avoids separation caused by impact and vibration during the adjustment process.

[0064] The switching of the two groups of fiber tension adjustment modes is achieved through a connecting sleeve 6. Compared with the use of two completely independent tension adjustment devices, the device structure is greatly simplified and the manufacturing cost of the device is reduced.

[0065] A positioning groove is provided on the connecting sleeve 6, a positioning block 7 is slidably connected in the connecting groove 46, a positioning protrusion 64 adapted to the positioning groove is provided on the back of the positioning block 7, a positioning plug ring is provided on the positioning block 7, a positioning plate 71 is provided on the tensioning adjustment frame 4, two positioning holes are provided in the positioning plate 71, and a positioning pin 72 adapted to the positioning plug ring is inserted in the positioning holes.

[0066] When the staff needs to switch the adjustment mode of the equipment, firstly, the positioning pin 72 is pulled out from the positioning hole of the positioning plate 71 .

[0067] This operation releases the external locking of the positioning block 7 , allowing the positioning block 7 to slide freely in the connecting groove 46 .

[0068] Since the positioning block 7 and the connecting sleeve 6 have not yet formed a locking connection (the positioning protrusion 64 is not embedded in the positioning groove), the connecting sleeve 6 is also in a freely movable state at this time, creating conditions for subsequent mode switching operations.

[0069] If the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58 are to be separated to realize a mode of adjusting the two groups of fibers separately, the staff pushes the connecting sleeve 6 to slide in the connecting groove 46 .

[0070] As the connecting sleeve 6 moves, it gradually separates from the connecting protrusion 62 on one of the bidirectional threaded rods, while remaining connected to the other bidirectional threaded rod (the second bidirectional threaded rod 58 ).

[0071] During this process, the positioning block 7 slides in the connecting groove 46 together with the connecting sleeve 6 , because the positioning block 7 and the connecting sleeve 6 are not locked at this time, and will not hinder the movement of the connecting sleeve 6 .

[0072] When it is necessary to connect the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58 for synchronous adjustment mode, the staff pushes the connecting sleeve 6 in reverse to move it to the middle position of the connecting groove 46, ensuring that the connecting hole 61 on the connecting sleeve 6 is simultaneously adapted and connected with the connecting protrusion 62 on the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58.

[0073] Likewise, the positioning block 7 moves along with the connecting sleeve 6 and does not affect the positioning operation of the connecting sleeve 6 .

[0074] When the connecting sleeve 6 moves to the desired position and the mode switching is completed, the staff pushes the positioning block 7 to slide in the connecting groove 46 until the positioning protrusion 64 on the back of the positioning block 7 is accurately embedded in the positioning groove provided on the connecting sleeve 6.

[0075] At this time, the connecting sleeve 6 and the positioning block 7 are relatively fixed.

[0076] Next, the positioning pin 72 is inserted into the corresponding positioning hole on the positioning plate 71 , and is tightly matched with the positioning insert ring on the positioning block 7 .

[0077] In this way, the positioning block 7 is firmly fixed at the current position in the connecting groove 46. Since the connecting sleeve 6 and the positioning block 7 are locked, the position of the connecting sleeve 6 is also fixed, thereby ensuring the stable position of the bidirectional screw 5 (including the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58) in the corresponding mode, and the staff can perform subsequent fiber tension adjustment operations.

[0078] During the adjustment process, since the position of the connecting sleeve 6 is locked, the rotation of the bidirectional screw 5 will only affect the corresponding adjustment plate 44 and the tensioning spring 45 according to the set mode (individual adjustment or synchronous adjustment), thereby achieving precise tension adjustment.

[0079] By adopting the above positioning and locking system, one staff member can independently complete the switching of the equipment adjustment mode and the adjustment of the tension degree.

[0080] Workers do not need to collaborate with multiple people to fix parts or operate complex processes, which greatly saves human resources.

[0081] In small production workshops with limited manpower, the single-operator feature of this equipment can significantly improve work efficiency and make production arrangements more flexible.

[0082] By simply plugging and unplugging the positioning pin 72 and the sliding positioning block 7 and the connecting sleeve 6, the first bidirectional threaded rod 57 and the second bidirectional threaded rod 58 can be separated or connected, and the switching of the adjustment mode can be quickly completed.

[0083] Compared with traditional equipment that requires complex disassembly and assembly processes to change adjustment modes, the above equipment greatly shortens the mode switching time and improves production efficiency.

[0084] In response to frequent changes in demand for different orders, we can quickly adjust equipment and respond to production tasks in a timely manner.

[0085] The precise matching design of the positioning groove and the positioning protrusion 64 , as well as the tight fit between the positioning pin 72 and the positioning insert ring, can ensure that the connecting sleeve 6 is accurately fixed at the desired position.

[0086] This ensures that the bidirectional screw 5 is always in a stable and accurate working state when adjusting the tension. Whether it is a single adjustment or a synchronous adjustment mode, the adjustment accuracy can be guaranteed, and inaccurate tension adjustment caused by position deviation of the connecting sleeve 6 can be avoided, thereby improving the production quality of polyester fiber.

[0087] A threaded blind hole is arranged on the back of the tensioning and adjusting frame 4, and an extension plate is arranged on the mounting frame 1. The extension plate has a threaded through hole. The tensioning and adjusting frame 4 is detachably connected to the mounting frame 1 through the threaded through hole, the threaded blind hole and bolts.

[0088] By providing a threaded blind hole on the back of the tensioning and adjusting frame 4 and opening a threaded through hole on the extension plate of the mounting frame 1, the two are detachably connected by bolts, so that the equipment is easy to operate during assembly.

[0089] The staff only needs to pass the bolts through the threaded through holes of the extension plate and screw them into the threaded blind holes of the tensioning and adjusting bracket 4 to complete the installation.

[0090] This design facilitates the installation and disassembly of the equipment in different production sites or when adjusting the production layout, and improves the flexibility of equipment installation.

[0091] When the tensioning and adjusting frame 4 of the equipment fails or needs maintenance, the detachable connection mode enables maintenance personnel to easily remove the tensioning and adjusting frame 4 from the mounting frame 1 .

[0092] Compared with the fixed connection structure, the tension adjustment frame 4 can be inspected, repaired or replaced with parts alone without complex disassembly of the entire equipment structure, which greatly shortens the maintenance time, reduces the maintenance cost, and improves the normal operation time and production efficiency of the equipment.

[0093] Another specific embodiment: A new polyester fiber is prepared using a new polyester fiber preparation device described in any of the above embodiments.

[0094] The novel polyester fiber comprises 70% polyethylene terephthalate (PET), 15% polyethylene glycol (PEG), 6% aliphatic polyester compounds, 5% quaternary ammonium salt monomers, and 2% nano titanium dioxide (TiO 2 ), 2% nano zinc oxide (ZnO).

[0095] By adding nano-titanium dioxide and nano-zinc oxide, and optimizing the spinning and post-processing processes, the tensile strength and modulus of the fiber are significantly improved, allowing it to withstand greater external forces and not easily break or deform, meeting the needs of industrial textiles, high-performance sports equipment and other application scenarios with high requirements for material strength.

[0096] The hydrophilic monomer polyethylene glycol is introduced for copolymerization modification, and a large number of hydrophilic groups are introduced into the fiber molecular chain, which makes it have good moisture absorption properties. It can quickly absorb sweat from the skin surface and quickly conduct it to the fiber surface for evaporation, keeping the skin dry and comfortable, greatly improving the wearing experience, and is especially suitable for sportswear and daily clothing.

[0097] Quaternary ammonium salt monomers containing antibacterial functional groups are connected to the polyester molecular chain to make the fiber surface have a positive charge, which can attract and destroy the bacterial cell membrane structure, effectively inhibit the growth of common bacteria and fungi, prevent odor caused by microbial reproduction, and ensure clothing hygiene. It is especially suitable for underwear and indoor home textile products, which can reduce the frequency of cleaning and extend the service life of the product.

[0098] Adding aliphatic polyester compounds as biodegradable additives forms a degradable microphase structure in the fiber, which enables the fiber to gradually degrade in a natural environment or under specific conditions, reducing the long-term impact on the environment. This is in line with the concept of sustainable development, provides raw material support for environmentally friendly textiles, helps reduce plastic waste, and reduces the pressure of the textile industry on the environment.

[0099] Due to its many excellent properties, this new polyester fiber can be widely used in sports equipment, outdoor clothing, medical textiles, environmentally friendly home textiles and other fields, meeting the diverse needs of different industries and consumers for the functionality, comfort and environmental protection of textiles, and has high market value and social significance.

[0100] Embodiment 2 Based on the above embodiments, the present invention provides another technical solution: refer to Fig. 9 The present invention also includes a telescopic component, which includes a telescopic groove 8 opened on the connecting protrusion 62, a guide block 81 is arranged in the telescopic groove 8, one side of the guide block 81 is a downwardly offset tip, and the other side of the guide block 81 is provided with a groove, one end of the telescopic block 82 is rotatably connected to the connecting sleeve 6, and the other end of the telescopic block 82 is slidably connected in the telescopic groove 8.

[0101] By adopting the above design, when the connecting sleeve 6 is pushed back and quickly released, the telescopic block 82 can slide upward under the guidance of the guide block 81, and then be stuck on the other side of the guide block 81 under the drive of the connecting spring 63, so as to separate the connecting sleeve 6 from the 5 positioning block 7, so that they can be adjusted separately, and there is no need for the staff to hold the connecting sleeve 6 by hand to overcome the elastic force of the connecting spring 63 to separate it from the 5 positioning block 7, making the use process more reliable.

[0102] When it is necessary to connect the 5 positioning blocks 7 with the 5 telescopic slots 8, the connecting sleeve 6 can be pushed again to separate the telescopic block 82 from the guide block 81. Under the action of gravity, the telescopic block 82 automatically falls down, and then the connecting sleeve 6 is released again. Driven by the connecting spring 63, the telescopic block 82 is reset, and the connection between the 5 positioning blocks 7 and the 5 telescopic slots 8 is completed.
