Description

Technical Field

[0001] This utility model relates to the field of nylon staple fiber processing, specifically to a nylon staple fiber stretching and shaping device. Background Technology

[0002] During the processing of nylon staple fiber, the filamentous material needs to be stretched to the required length and diameter. Nylon staple fiber stretching and setting equipment is a key piece of equipment in nylon staple fiber production. It is mainly used to stretch nascent fibers to improve the orientation of the macromolecules of the fibers, thereby improving their physical and mechanical properties. This equipment usually consists of multiple stretching rollers and can be heated between the stretching machines to ensure the quality and performance of the final product.

[0003] Chinese patent CN218404525U discloses a nylon fiber spinning, stretching, and shaping device, including a housing, a motor, and nylon filaments. Rollers are installed on one side of the housing, and a rotating rod is rotatably connected through the housing at the end away from the rollers. A rotating device is installed inside the housing, which includes extrusion teeth. The extrusion teeth are divided into two, and a first rotating tooth and a second rotating tooth are welded to the same side of the two extrusion teeth. By using a separation sleeve set on the take-up rod, multiple nylon filaments can be limited and retracted to prevent the nylon filaments from becoming tangled during the retraction process.

[0004] The aforementioned patented nylon fiber spinning stretching and setting device does not preheat the material to be stretched during the stretching and setting process, and only achieves one stretching after preheating. The single high-strength stretching without preheating is prone to causing the nylon staple fiber to break. Utility Model Content

[0005] The purpose of this invention is to provide a nylon staple fiber stretching and setting device. Nylon staple fibers are conveyed from the inlet and discharged from the outlet, and then sequentially come into contact with the liquid inside the water tank and the steam discharged from the diversion pipe. Stretching is performed during the contact and heating process. Two independent stretching operations can achieve the corresponding required stretching of nylon staple fibers. Segmented stretching can avoid breakage and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nylon staple fiber stretching and setting device, comprising a shell, an inlet on one side of the outer shell, an outlet on the other side of the shell, a steam generator at the front end of the shell, three diversion pipes evenly distributed laterally in the middle of the interior of the shell, a water tank at the lower end of the interior of the shell, a third drive roller on one side between the water tank and the diversion pipes, a pair of first drive rollers on the other side between the water tank and the diversion pipes, a pair of fourth drive rollers on one side of the upper end of the interior of the shell, a pair of sixth drive rollers on the other side of the upper end of the interior of the shell, and the diversion pipes located between the fourth and sixth drive rollers.

[0007] Preferably, a transmission frame is provided at the upper part of the exterior of the water tank.

[0008] Preferably, a second transmission roller is provided between the upper end of the transmission frame and the diverter pipe, the fourth transmission roller is located above the third transmission roller, the sixth transmission roller is located above the first transmission roller, and a fifth transmission roller is provided at the upper end between the fourth and sixth transmission rollers.

[0009] Preferably, a seventh transmission roller is provided on the other side of the sixth transmission roller.

[0010] Preferably, the seventh transmission roller is located on one side of the discharge port, and an eighth transmission roller is provided at the lower end between the discharge port and the seventh transmission roller.

[0011] Preferably, a fan is provided between the seventh and eighth transmission rollers, and an air outlet is provided on one side of the front end of the outer casing, with the air outlet corresponding to the fan.

[0012] Preferably, the diverter pipe is sealed to the steam generator.

[0013] Preferably, the front end of the water tank is provided with a threaded rod that passes through the transmission frame, and the outside of the threaded rod is threadedly engaged with the through position of the transmission frame.

[0014] Preferably, a sealing plate is provided on the upper end of one side of the outer wall of the outer shell, the upper end of the outer shell, and the other side of the outer wall of the outer shell, and the sealing plate is sealed to the outer shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, when conveying nylon staple fibers into the outer casing, the nylon staple fibers first submerge inside the water tank and then move to the upper end of the distribution pipe after transmission. This allows the nylon staple fibers to be heated sequentially, and after each heating, they undergo corresponding stretching. Different stretching intensities correspond to different heating temperatures, preventing the nylon staple fibers from breaking due to excessive single stretching. On the other hand, because the water tank is located at the lower end of the distribution pipe, the heat from the heated liquid inside the water tank moves vertically upwards to the steam outlet of the distribution pipe, allowing for heat reuse and avoiding waste. Finally, since the nylon staple fibers in contact with the liquid inside the water tank will adhere to the liquid, the liquid will be squeezed out during subsequent transmission and stretching by the first, second, third, fourth, fifth, and sixth transmission rollers. The liquid will not be wasted; it will flow vertically downwards and eventually fall back into the water tank, allowing for liquid recycling and collection. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, a nylon staple fiber stretching and shaping device of this embodiment includes a housing 1. A feed inlet 4 is provided on one side of the outer side of the housing 1, and a discharge outlet 5 is provided on the other side of the housing 1. During the stretching process, the nylon staple fiber is fed into the housing 1 through the feed inlet 4 and discharged from the discharge outlet 5 after stretching.

[0025] The front end of the outer shell 1 is equipped with a steam generator 7, and three diversion pipes 8 are evenly distributed laterally in the middle of the inner shell 1. The high-temperature steam discharged from the steam generator 7 is diverted by the diversion pipes 8 and transmitted to the middle of the inner shell 1, contacting the nylon short fibers to be stretched transmitted at the upper end of the inner shell 1. The diversion pipes 8 are sealed to the steam generator 7.

[0026] In addition, a water tank 9 is provided at the lower end of the inner shell 1. The nylon short fibers transmitted from the feed port 4 into the inner shell 1 are embedded in the water tank 9 to complete the heating. A third transmission roller 14 is provided on one side between the water tank 9 and the diversion pipe 8, and a pair of first transmission rollers 12 are provided on the other side between the water tank 9 and the diversion pipe 8. The pair of first transmission rollers 12 can be transmitted by rotating after clamping the nylon short fibers.

[0027] like Figure 3 As shown, to facilitate the embedding of nylon staple fibers into the water tank 9, a transmission frame 10 is provided at the upper end of the exterior of the water tank 9, and a threaded rod 11 is provided at the front end of the water tank 9, penetrating the transmission frame 10. The outer surface of the threaded rod 11 is threadedly engaged with the penetration position of the transmission frame 10. The longitudinal position of the transmission frame 10 can be adjusted by rotating the threaded rod 11. Adjusting the longitudinal position of the transmission frame 10 can press the transmitted nylon staple fibers, causing the nylon staple fibers to submerge into the water tank 9.

[0028] Among them, a second transmission roller 13 is provided between the upper end of the transmission frame 10 and the diversion pipe 8. The second transmission roller 13 is located between the third transmission roller 14 and a pair of first transmission rollers 12. The nylon staple fiber transmitted between the third transmission roller 14 and the pair of first transmission rollers 12 is straightened and stretched through the second transmission roller 13.

[0029] In order to stretch the nylon staple fiber in segments, a pair of fourth transmission rollers 15 are provided on one side of the upper part of the inner shell 1. The fourth transmission rollers 15 are located above the third transmission roller 14. A pair of sixth transmission rollers 17 are provided on the other side of the upper part of the inner shell 1. The sixth transmission rollers 17 are located above the first transmission roller 12. The diversion pipe 8 is located between the fourth transmission rollers 15 and the sixth transmission rollers 17. The nylon staple fiber transmitted between the sixth transmission rollers 17 and the fourth transmission rollers 15 will come into contact with the steam discharged from the diversion pipe 8 and be heated. Heating facilitates secondary stretching.

[0030] Among them, a fifth transmission roller 16 is provided at the upper end between the fourth transmission roller 15 and the sixth transmission roller 17. The nylon short fiber between the fourth transmission roller 15 and the sixth transmission roller 17 can be straightened by the fifth transmission roller 16 to achieve secondary stretching. Multi-segment stretching can cope with different heating temperatures.

[0031] A seventh transmission roller 18 is provided on the other side of the sixth transmission roller 17, such as... Figure 4As shown, the seventh transmission roller 18 is located on one side of the discharge port 5. In order to avoid high temperature and difficulty in collection of the nylon staple fiber discharged from the discharge port 5, an eighth transmission roller 19 is provided at the lower end between the discharge port 5 and the seventh transmission roller 18. The nylon staple fiber transmitted between the seventh transmission roller 18 and the discharge port 5 will be transmitted by the eighth transmission roller 19 and transmitted downward. The restriction of the eighth transmission roller 19 can facilitate the heat dissipation and cooling of the nylon staple fiber.

[0032] Among them, a fan 6 is provided between the seventh transmission roller 18 and the eighth transmission roller 19, and an air outlet 2 is provided on one side of the front end of the outer shell 1, and the air outlet 2 corresponds to the fan 6. The fan 6 draws the gas outside the outer shell 1 and sends it into the interior of the outer shell 1. After the gas is sent into the interior of the outer shell 1 between the seventh transmission roller 18 and the eighth transmission roller 19, the heat is discharged from the air outlet 2.

[0033] To facilitate the pre-installation of nylon staple fibers and the inspection of the interior of the outer casing 1, a sealing plate 3 is provided on the upper end of one side of the outer wall of the outer casing 1, the upper end of the exterior of the outer casing 1, and the other side of the outer wall of the outer casing 1. The sealing plate 3 is sealed to the outer casing 1. The heat can be limited by the filling of the outer casing 1 through the sealing plate 3 to prevent heat leakage.

[0034] One end of the first transmission roller 12, the fourth transmission roller 15 and the sixth transmission roller 17 is equipped with a motor, which can drive them to rotate through the output of the motor, thereby realizing the transmission of nylon staple fiber.

[0035] Working principle: When using the device to stretch and shape nylon staple fibers, the nylon staple fibers extend into the housing 1 from the inlet 4. After being pressed by the transmission frame 10, the nylon staple fibers are embedded into the water tank 9 and come into contact with the high-temperature liquid inside the water tank 9. After being pressed by the transmission frame 10, the nylon staple fibers are clamped by a pair of first transmission rollers 12 and then transported to the third transmission roller 14. The nylon staple fibers are stretched by the compression of the second transmission roller 13 between the third transmission roller 14 and the first transmission roller 12. The nylon staple fibers at the position of the third transmission roller 14 are then stretched by the fourth transmission roller 15. After being clamped, the nylon staple fiber is conveyed towards a pair of sixth drive rollers 17. It is stretched between the pair of sixth drive rollers 17 and the pair of fourth drive rollers 15 by the fifth drive roller 16. During the stretching process, it comes into contact with the high-temperature steam discharged from the position of the diversion pipe 8. The nylon staple fiber conveyed by the pair of sixth drive rollers 17 is guided by the seventh drive roller 18 and then conveyed to the discharge port 5 for discharge. During the discharge process, the nylon staple fiber between the seventh drive roller 18 and the discharge port 5 is restricted by the eighth drive roller 19 and then contacts the exhaust position of the fan 6 longitudinally downward, and the stretched nylon staple fiber is cooled at a uniform speed.
