DETAILED DESCRIPTION

[0020] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0021] As shown in Figure 1 , in the embodiment, a composite filament production device based on a multi-roller WINGS-FDY device is an ITY composite filament production device designed based on a Barmag 8-roller WINGS-FDY device, which is composed of a spinning assembly system, a ring blowing system, a bundling system and a roller system. The POY spinneret accessory 2 and the POY spinneret 3 are arranged on the right side of the ring blowing partition 1, and the FDY spinneret accessory 10 and the FDY spinneret 11 are arranged on the left side of the ring blowing partition 1. The POY windless zone 4 below the POY spinneret 3 is 10 mm longer than the FDY windless zone 12 below the FDY spinneret 11. The POY ring blowing device 5, the POY oiling nozzle rack 6, the POY guide hook rack 7, the POY filament distributor 8 and the ninth roller 9 are arranged below the POY windless zone 4. The FDY ring blowing device 13, the FDY guide hook rack 14, the FDY pre-networking rack 15, the FDY filament distributor 16, the FDY filament presser 17 and the first roller 18 are arranged below the FDY windless zone 12. The ring blowing system includes the POY ring blowing device 5 and the FDY ring blowing device 13. The ring blowing partition 1 is arranged between the POY ring blowing device 5 and the FDY ring blowing device 13 to separate the two. The ring blowing partition 1 cooperates with independent ring blowing valves to realize independent control of the ring blowing pressure of the POY ring blowing device 5 and the FDY ring blowing device 13.

[0022] In combination with Figure 2 , Figure 3 and Figure 4As shown, in the present embodiment, the spinning assembly system comprises a POY spinneret 3 and an FDY spinneret 11, both of which are divided into four spinning hole regions, each of which can emit an equal number of POY primary filaments or FDY primary filaments, and the spinning hole regions of the POY spinneret 3 and the FDY spinneret 11 are divided in the same way. Since the Barmag 8-roll WINGS FDY is a 32-head device, 32 ITY composite filaments need to be produced, and the spinneret must be specially designed to meet the hardware requirements for producing ITY composite filaments. The POY spinneret 3 and the FDY spinneret 11 are both divided into two by the symmetrical line, and then 2 spinning hole regions are divided on each side of the spinneret, the POY spinneret 3 is P1, P2, P3, P4, and the FDY spinneret 11 is Z1, Z2, Z3, Z4, that is, each POY spinneret 3 and FDY spinneret 11 is planned to have 4 spinning hole regions, and can realize that each spinneret emits 4 POY or FDY primary filaments. In the entire spinning assembly system, there are 8 sets of POY assemblies and FDY assemblies, and each POY assembly and FDY assembly emits 32 primary filaments, and a total of 64 primary filaments can be emitted in one spinning position, so as to be subsequently twisted into 32 ITY composite filaments.

[0023] Among them, the FDY ring blowing device 13 is controlled to be 35 Pa in the present embodiment, and the POY ring blowing device 5 is controlled to be 30 Pa in the present embodiment. At the same time, in order to adapt to the production of ITY composite filaments and ensure the stability of production, the lengths of the POY windless zone 4 and the FDY windless zone 12 are not the same, and the POY windless zone 4 is 10 mm longer than the FDY windless zone 12, and the specific method is that the POY spinneret 3 is 10 mm shorter than the FDY spinneret 11.

[0024] In combination with Figure 4 and Figure 5As shown, the bundling system includes a POY bundling device and an FDY bundling device. The POY oiling nozzle in the POY bundling device and the FDY pre-network frame 15 in the FDY bundling device can be independently adjusted in position and angle on the fixed support of the bundling system. In this embodiment, the POY bundling device includes a POY oiling nozzle frame 6, a POY guide hook frame 7, a POY filament separator 8, a POY spinneret accessory 2, and a POY spinneret 3 that discharges 32 POY primary filaments. The POY primary filaments are cooled by a POY windless zone 4, then enter the oil nozzles of the POY oiling nozzle frame 6 for oiling, then are guided by the guide hooks on the POY guide hook frame 7 below, then pass through the POY filament separator 8 to enter the roller system. In this embodiment, the FDY bundling device includes an FDY guide hook frame 14, an FDY pre-network frame, an FDY filament separator 16, an FDY filament presser 17, an FDY spinneret accessory 10, and an FDY spinneret 11 that discharges 32 FDY primary filaments. The FDY primary filaments are cooled by an FDY windless zone 12, then enter the guide hooks of the FDY guide hook frame 14 for bundling, then pass through the pre-networkers on the FDY pre-network frame below to apply network points, then pass through the FDY filament separator 16, the FDY filament presser 17, and enter the roller system for oriented drawing of the FDY primary filaments. The POY bundling device and the FDY bundling device are two independent bundling devices. The fixed supports of the two devices are specially designed. The fixed support of the FDY bundling device can be adjusted in position up and down, left and right, and front and back, and the POY oiling nozzle frame 6 and the FDY pre-network frame can be adjusted in inclination angle, according to the original positioning holes and guide rails on the Barmag equipment, to meet the process production requirements.

[0025] The POY bundling device and the FDY bundling device are two independent bundling devices. The fixed supports of the two devices are specially designed. The fixed support of the FDY bundling device can be adjusted in position up and down, left and right, and front and back, and the POY oiling nozzle frame 6 and the FDY pre-network frame can be adjusted in inclination angle, according to the original positioning holes and guide rails on the Barmag equipment, to meet the process production requirements.

[0026] The two sets of bundling devices have high flexibility in the production process. Not only can the position be adjusted, but also the angle can be fine-tuned according to the needs. This design aims to meet the requirements of different production processes, improve production efficiency and product quality.

[0027] The independence between the POY bundling device and the FDY bundling device allows the two devices to be optimized for different production steps. In actual production, the two sets of bundling devices can be reasonably configured according to the production process and equipment layout to maximize the use of production resources.

[0028] The specially designed fixing supports provide stable support for the two sets of bundling devices, ensuring the stability and safety of the equipment during high-speed operation. At the same time, the design of positioning holes and guide rails makes the installation and debugging of the device more convenient, reducing the maintenance cost of the equipment.

[0029] The tilt angle adjustment function of the POY oil nozzle rack 6 and the FDY pre-network rack allows the oil nozzle and the pre-network to be precisely positioned according to production needs. This design not only improves the degree of automation in the production process, but also helps to reduce losses in production and improve product qualification rates.

[0030] The roller system includes an FDY filament roller device and a POY filament roller device. The FDY filament roller device includes a first roller 18, a second roller 19, a third roller 20, a fourth roller 21, a fifth roller 22, a sixth roller 23, and an FDY oiling pan 24. The FDY primary filament is less than one turn on each roller surface in the FDY filament roller device. The temperature of the subsequent roller is greater than or equal to the previous roller, and the winding speed of the subsequent roller is greater than the previous roller. In this embodiment, the first roller 18 speed is 1100 m / min, the second roller 19 speed is 1150 m / min, the third roller 20 speed is 1200 m / min, the fourth roller 21 speed is 3470 m / min, the fifth roller 22 speed is 3480 m / min, and the sixth roller 23 speed is 3490 m / min. The filament is less than one turn on each roller surface. The second roller 19 temperature is 60°C, the third roller 20 temperature is 60°C, the fourth roller 21 temperature is 110°C, the fifth roller 22 temperature is 110°C, and the sixth roller 23 temperature is 110°C. The temperature of the first roller 18 and the second roller 19 is room temperature.

[0031] In the roller system, the FDY filament roller device and the POY filament roller device play a core role. The FDY filament roller device mainly includes a first roller 18, a second roller 19, a third roller 20, a fourth roller 21, a fifth roller 22, a sixth roller 23, and an FDY oiling pan 24. These rollers work together to ensure that the FDY primary filament is tightly attached to each roller surface, less than one turn. It is particularly noteworthy that the temperature and winding speed of the subsequent roller are greater than those of the previous roller, which helps to improve the quality and performance of the filament.

[0032] Specific to the speed of each roller, the speed of the first roller 18 is set to 1100 m / min, and the speeds of the subsequent second roller 19, third roller 20 and fourth roller 21 are 1150 m / min, 1200 m / min and 3470 m / min respectively. The speeds of the fifth roller 22 and the sixth roller 23 are 3480 m / min and 3490 m / min respectively. Such a speed gradient design ensures the continuity and stability of the filament production, and the temperature gradient design is conducive to maintaining the stability of the production and improving the quality of the filament.

[0033] On the other hand, the POY filament roller device includes a ninth roller 9, and the POY filament does not need to be wound on the roller for multiple turns, but only needs to be attached to the roller for less than one turn. The starting operation is simple, and the accidental loss of product quality caused by the operator's mistake can be avoided on the premise of ensuring the stability and quality of the product.

[0034] Through such a design, the FDY filament roller device and the POY filament roller device can efficiently complete the winding and stretching work of the nascent filament, thereby producing high-quality filament products. In actual production, the temperature and speed of each roller can be adjusted according to needs, which can further optimize the production process and meet the production needs of different varieties and specifications of filaments.

[0035] In this embodiment, in order to ensure the stability of the production, the POY filament and the FDY filament can be well compounded after being processed respectively, the winding speed of the last roller in the POY filament roller device exceeds the winding speed of the first roller in the FDY filament roller device by 30 m / min, the last roller in the POY filament roller device is the ninth roller 9, the first roller in the FDY filament roller device is the first roller 18, the speed of the ninth roller 9 in the POY filament roller device is 1130 m / min, the filament is attached to the roller surface for less than one turn, and the temperature of the ninth roller 9 is room temperature.

[0036] As Figure 1As shown, in this embodiment, the POY filament and the FDY filament converge at the seventh roller element 25. At this point, the POY filament and the FDY filament are in a parallel state. Due to the high-speed rotation of the FDY filament through the roller elements, the speed difference varies greatly, which can cause the filament path of the FDY filament to deviate. Therefore, the center of the filament path of the two in the same spool may not completely coincide. To avoid excessive speed difference between the two in the early stage, we can adjust the position of the POY filament divider 8 connecting rod base to prevent friction, shaking and jumping. After acceleration through the seventh roller, the POY filament and the FDY filament have the same speed, which makes them easily enter the main networker 26 porcelain element, complete the network process, and then apply the network through the main networker 26 to form the ITY composite filament. Finally, the ITY composite filament is transported to the 32-head first winding machine 28 and the second winding machine 29 for winding and forming.

[0037] In Figure 1 we can see that the POY filament and the FDY filament converge at the seventh roller element 25. At this point, the POY filament and the FDY filament converge and maintain a parallel state at the seventh roller element 25. It is worth noting that due to the high-speed rotation of the FDY filament through the FDY filament roller element device, the speed difference varies greatly, which can cause the filament path of the FDY filament to deviate. Therefore, the center of the filament path of the two in the same spool may not completely coincide.

[0038] To solve this problem, we can adjust the position of the POY filament divider 8 connecting rod base to avoid friction, shaking and jumping due to excessive speed difference between the two in the early stage. After acceleration through the seventh roller, the POY filament and the FDY filament have the same speed, which makes them easily enter the main networker 26 porcelain element, complete the network process.

[0039] Next, the network points are applied through the main networker 26, so that the POY filament and the FDY filament are combined into the ITY composite filament. Finally, after the transportation through the eighth roller element 27, the ITY composite filament is sent to the 32-head first winding machine 28 and the second winding machine 29 for winding and forming.

[0040] By fine-tuning the convergence of the POY filament and the FDY filament at the seventh roller element 25, as well as the subsequent network process and winding and forming process, we can ensure that the center of the filament path of the two in the same spool tends to coincide, thereby improving the quality and production efficiency of the filament product. At the same time, by adjusting the position of the POY filament divider 8 connecting rod base, we can effectively reduce the friction, shaking and jumping phenomenon caused by excessive speed difference between the two in the early stage, which provides a guarantee for the smooth progress of the subsequent process flow.

[0041] After the POY filaments and the FDY filaments pass through the seventh roller 25 and are parallel, they are plying into the ITY composite yarn in the main networker 26. At this time, the pressure of the main networker 26 is set to 3.5 bar, which is to ensure the smooth progress of the plying process. The speed of the seventh roller 25 is 3500 m / min, which is to ensure that the POY filaments and the FDY filaments can keep stable running during the merging process. The speed of the eighth roller 27 is 3495 m / min, which is slightly lower than that of the seventh roller 25, so as to slow down the running speed of the composite yarn, facilitating the subsequent winding process.

[0042] The winding speed of the first winding machine 28 and the second winding machine 29 is also set to 3500 m / min, which is to ensure that the composite yarn can keep stable speed during the winding process. In the whole process, the speed and pressure of each component are jointly designed to achieve efficient and stable production.
