Description

Technical Field

[0001] This utility model relates to the field of fiber filament production technology, and in particular to a novel composite fiber filament and production apparatus. Background Technology

[0002] As people's living standards continue to improve, the requirements for the performance and quality of textile products are also getting higher and higher. In the existing technology, the production of fiber filaments is divided into multiple steps. Among them, fiber filament stretching is to pass polyester filaments through a heating box and achieve the purpose of stretching by raising the temperature of the fiber filaments.

[0003] A stretching device for polyester filament production disclosed in CN220503331U discloses a "base plate, an unwinding component on the left side of the base plate, a winding component on the right side of the base plate, and a heating component in the middle of the base plate, the heating component including a mounting arm fixedly installed on the base plate, etc., which has the technical effect of applying external force for stretching while heating and stretching, and stretching a large length".

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During the winding process of the motor-driven take-up coil, although the filament can be stretched, when the traction force suddenly increases, it is easy to apply a large force to the heated filament. The instantaneous excessive traction force will cause uneven local stress on the fiber filament, resulting in overstretching and uneven thickness, which will damage the uniformity and stability of the filament and affect the product quality and appearance. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a novel composite fiber filament and its production apparatus.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel composite fiber filament production device, comprising a base plate, a heating component and a traction component installed on the upper surface of the base plate, a buffer component provided on the upper surface of the base plate, the buffer component comprising a support first and a support second disposed above the base plate, a roller first rotatably connected inside the support first, a roller second rotatably connected inside the support second, two inner supports fixedly connected to the upper surface of the base plate, a U-shaped plate disposed between the two inner supports, a roller third rotatably connected inside the U-shaped plate, the roller third being located between the support first and the roller second.

[0007] By adopting the above technical solution, when the filament encounters a sudden change in traction force during the traction process, the buffer component can effectively buffer the change in tension by utilizing the contact between the roller and the filament and the movement of the U-shaped plate, thus preventing the filament from being overstretched due to uneven force and ensuring the forming quality of the filament.

[0008] Furthermore, the two ends of the U-shaped plate are respectively inserted into the sliding grooves opened on the adjacent sides of the two inner supports, and the U-shaped plate and the inner supports are slidably connected.

[0009] By adopting the above technical solution, this sliding connection method enables the U-shaped plate to move flexibly along the direction of the chute when the filament is subjected to a sudden increase in traction force, thereby driving the roller to adjust its position to offset part of the tension, maintain the stability of the tension on the filament, and improve the anti-interference ability in the filament production process.

[0010] Furthermore, an optical axis is fixedly connected to the upper surface of the U-shaped plate, and a counterweight plate is sleeved on the upper surface of the optical axis.

[0011] By adopting the above technical solution, the overall weight of the U-shaped plate can be changed by increasing or decreasing the number of counterweight plates, thereby adjusting the buffering capacity of the buffer assembly to different traction force changes. The buffering force can be flexibly adjusted according to actual production needs, enhancing the adaptability of the device to various production conditions.

[0012] Furthermore, two side plates are fixedly connected to the upper surface of the base plate, and a wire feeding roll is installed between the two side plates. The two ends of the wire feeding roll shaft pass through the side plates respectively, and the wire feeding roll and the side plates are rotatably connected.

[0013] By adopting the above technical solution, the unwinding spool is used to store the filament raw materials to be processed, and the filaments are smoothly released by rotation during the production process. Its rotational connection with the side plate ensures the smoothness of the unwinding process and provides a stable supply of raw materials for the continuous production of filaments.

[0014] Furthermore, a U-shaped clamping plate is fixedly connected to the upper surface of the base plate, and a roller is rotatably connected inside the U-shaped clamping plate.

[0015] By adopting the above technical solution, the combination of roller four and U-shaped clamp can reasonably guide the running path of the filament, so that the filament maintains the correct direction during the transfer from the unwinding coil to the subsequent processing components, avoiding problems such as tangling and deviation of the filament, and ensuring the orderly progress of the filament production process.

[0016] Furthermore, a tensioning assembly is provided at one end of the unwinding coil. The tensioning assembly includes a friction wheel fixedly connected to one end of the unwinding coil shaft. A connecting plate is fixedly connected to the upper surface of the base plate. A longitudinal plate is fixedly connected to one end of the connecting plate. A transverse plate is inserted into two transverse grooves opened inside the longitudinal plate. The transverse plate and the longitudinal plate are slidably connected. A pressure block is fixedly connected to one end of the two transverse plates. One side of the pressure block is in contact with the friction wheel.

[0017] By adopting the above technical solution, the tensioning assembly can effectively control the rotational resistance of the unwinding coil through the friction between the pressure block and the friction wheel, thereby precisely adjusting the tension of the filament during the stretching process, ensuring that the stretching force of the filament meets the production requirements, and improving the quality stability of the filament products.

[0018] Furthermore, an inclined plate is inserted between the two horizontal plates, and the inclined plate is rotatably connected to the horizontal plates via a pivot.

[0019] By adopting the above technical solution, the rotating connection structure between the inclined plate and the horizontal plate allows the inclined plate to rotate flexibly under its own weight and external force, thereby driving the horizontal plate to move and adjusting the position of the pressure block. This changes the friction between the pressure block and the friction wheel, making it easier to finely adjust the filament tension.

[0020] Furthermore, a roller is installed in the groove at the top of the inclined plate, the roller is in contact with the longitudinal plate, and a square box is fixedly connected to the top of the inclined plate.

[0021] By adopting the above technical solution, the roller setting reduces the frictional resistance between the inclined plate and the longitudinal plate, making the rotation of the inclined plate smoother. At the same time, by adding or removing weights in the square box, the force of the inclined plate on the pressure block can be easily adjusted, further improving the convenience and accuracy of filament tension adjustment.

[0022] A novel composite fiber filament comprises a core, a functional layer, and a surface layer arranged sequentially from the inside out. The core is made of high-strength polyester fiber, the functional layer is made of antibacterial material, and the surface layer is made of hydrophilic material.

[0023] By adopting the above technical solutions, the high-strength polyester fiber core provides the filament with excellent mechanical strength and toughness, ensuring that the filament is not easily broken during processing and use; the antibacterial material of the functional layer can effectively inhibit bacterial growth and give the filament good hygiene performance; the hydrophilic material of the surface layer can quickly absorb and expel moisture, improving the wearing comfort of the filament. The three-layer structure works synergistically to significantly improve the overall performance of the composite fiber filament.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. In this application, the sudden change in traction force of the traction component can be effectively dealt with during filament transmission. When the traction force suddenly increases, the roller can drive the U-shaped plate to move, buffer the change in tension, avoid uneven local stress and excessive stretching of the filament, greatly improve the filament forming quality, reduce the defect rate, and ensure stable and continuous production.

[0026] 2. In this application, the operator can increase or decrease the number of counterweight plates according to different traction force changes in actual production, accurately change the weight of the U-shaped plate, flexibly adjust the buffering capacity of the buffer assembly to different traction force changes, significantly enhance the adaptability of the device to various production conditions, and broaden its application range.

[0027] 3. In this application, the tensioning component at one end of the unwinding coil utilizes the friction between the pressure block and the friction wheel to achieve precise control of the tension during the filament stretching process, ensuring uniform force during filament stretching, effectively reducing filament quality fluctuations caused by unstable tension, and improving product quality stability.

[0028] 4. In this application, the rollers reduce the frictional resistance between the inclined plate and the longitudinal plate, making the adjustment process easier and smoother. The square box allows operators to quickly adjust the force of the inclined plate on the pressure block by adding or removing weights, thereby achieving convenient and accurate adjustment of the filament tension and improving production efficiency.

[0029] 5. In this application, the high-strength polyester fiber core gives the filament excellent mechanical strength and toughness, ensuring that it is not easily broken during processing and use; the antibacterial material of the functional layer effectively inhibits bacterial growth and provides a healthy and hygienic user experience; the hydrophilic material of the surface layer quickly absorbs and releases moisture, significantly improving wearing comfort. The three-layer structure works synergistically to greatly improve the comprehensive performance of the composite fiber filament in many aspects. Attached Figure Description

[0042] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown in the embodiment of this application, a novel composite fiber filament production apparatus is disclosed, including a base plate 1.

The two ends of the shaft of the wire feeding roll 410 pass through the side plates 411 respectively, and the wire feeding roll 410 and the side plates 411 are rotatably connected.

[0046] A U-shaped clamping plate 412 is fixedly connected to the upper surface of the base plate 1, and a roller 413 is rotatably connected inside the U-shaped clamping plate 412.

[0047] A tensioning component 5 is provided at one end of the unwinding coil 410. The tensioning component 5 includes a friction wheel 57 fixedly connected to one end of the shaft of the unwinding coil 410. A connecting plate 51 is fixedly connected to the upper surface of the base plate 1. A longitudinal plate 58 is fixedly connected to one end of the connecting plate 51. A transverse plate 52 is inserted into two transverse grooves opened inside the longitudinal plate 58. The transverse plate 52 and the longitudinal plate 58 are slidably connected. A pressure block 56 is fixedly connected to one end of the two transverse plates 52. One side of the pressure block 56 is in contact with the friction wheel 57.

[0048] An inclined plate 53 is inserted between the two horizontal plates 52, and the inclined plate 53 is rotatably connected to the horizontal plates 52 via a pivot.

[0049] A roller 55 is installed in the groove at the top of the inclined plate 53. The roller 55 fits into the longitudinal plate 58. A square box 54 is fixedly connected to the top of the inclined plate 53.

[0050] The operating principle of the novel composite fiber filament production device in this embodiment is as follows: In the initial stage of filament production, the unwinding spool 410 undertakes the unwinding task. The two ends of the unwinding spool 410's rotating shaft pass through the side plate 411 and are rotatably connected to it. Driven by production demand, it starts to rotate, gradually releasing the filament. The released filament first enters the heating component 2. The heating component 2 is composed of a heating roller, a heating controller, a heating rod, a slider, a spring, a guide rod, a chute, an mounting arm, and a pressure roller, as disclosed in CN220503331U, a stretching device for polyester filament production. The heating controller controls the heating rod to work and generate heat. The heat is transferred to the heating roller. At the same time, the pressure roller, under the action of the spring, tightly presses the filament onto the heating roller, realizing the initial heating and temperature rise of the filament, preparing it for the subsequent stretching process, so that the filament has better plasticity at a suitable temperature.

[0051] The filament that has completed the initial heating continues to move forward under the traction of the traction component 3. The traction component 3 consists of a motor, a support base 2 and a take-up coil in a stretching device for polyester filament production disclosed in CN220503331U. The motor drives the take-up coil to rotate, and the filament is moved by the tension of the filament, thereby stretching the filament in the process.

[0052] During the transfer of the filament from the heating assembly 2 to the traction assembly 3, the buffer assembly 4 plays a crucial role. The filament passes under the fourth roller 413, then around the upper side of the first roller 44, passes under the third roller 47, and finally winds around the upper side of the second roller 45 before connecting with the take-up coil of the traction assembly 3. At this point, the filament between the third roller 47 and the first roller 44 is vertical, and the filament between the third roller 47 and the second roller 45 is also vertical. When the take-up coil of the traction assembly 3 suddenly increases its winding speed for the filament due to various reasons, i.e., when the traction force suddenly increases, the filament will exert more force on the third roller 47. With a large force, since the two ends of the U-shaped plate 46 are inserted into the sliding grooves on the adjacent side of the two inner supports 42 and can slide, the roller 3 47 will drive the U-shaped plate 46 to move upward, thereby buffering the sudden increase in traction force on the filament, avoiding excessive stretching caused by uneven local force on the filament, and effectively preventing the filament from becoming uneven in thickness. In addition, the operator can adjust the force on the U-shaped plate 46 and the roller 3 47 by adding or removing the counterweight plate 49 sleeved on the surface of the optical shaft 48, thereby changing the range of varying traction force applicable to the buffer device, so that it can better adapt to different production conditions.

[0053] Under the gravity of the square box 54 and the inclined plate 53, the inclined plate 53 applies a force to the pressure block 56, so that the pressure block 56 and the friction wheel 57 maintain a suitable fit and friction. The friction wheel 57 is fixed to one end of the shaft of the unwinding reel 410. This friction increases the resistance during the rotation of the unwinding reel 410, ensuring that the filament maintains a stable tension during the stretching process. The operator can also place a weight inside the square box 54. By changing the gravity of the square box 54 and the inclined plate 53, the force between the pressure block 56 and the friction wheel 57 can be adjusted, thereby realizing flexible adjustment of the filament stretching force. At the same time, the sliding connection structure between the horizontal plate 52 and the vertical plate 58 ensures that the pressure block 56 can move horizontally and always maintain a good fit with the friction wheel 57, ensuring a stable and reliable tensioning effect.

[0054] like Figure 3 As shown, this embodiment also discloses a novel composite fiber filament, comprising a core 6, a functional layer 7, and a surface layer 8 arranged sequentially from the inside out. The core 6 is made of high-strength polyester fiber, the functional layer 7 is made of antibacterial material, and the surface layer 8 is made of hydrophilic material.

[0055] The novel composite fiber filament in this embodiment has the following effects: the high-strength polyester fiber core 6 provides the filament with excellent mechanical strength and toughness, ensuring that the filament is not easily broken during processing and use; the antibacterial material of the functional layer 7 can effectively inhibit bacterial growth, giving the filament good hygiene properties; the hydrophilic material of the surface layer 8 can quickly absorb and expel moisture, improving the wearing comfort of the filament. The three-layer structure works synergistically to significantly improve the overall performance of the composite fiber filament.
