Technical Field

[0001] The utility model relates to the technical field of fiber processing, and particularly relates to an aramid fiber high-temperature crimping device. Background Art

[0002] An aramid fiber high-temperature crimping device is a device specifically used for crimping aramid fibers during the high-temperature treatment process. This device is of great significance in the field of fiber processing technology. It improves the performance of fibers or meets specific processing requirements by subjecting aramid fibers to high-temperature treatment and combining the crimping process, and has broad application prospects in the fields of textile, materials science, and industrial manufacturing.

[0003] During the processing of the existing aramid fiber high-temperature crimping device, there is a lack of a heat dissipation structure near the discharge guiding plate, which may cause the high-temperature crimped aramid fibers to continue to be heated during the discharge process, affecting the cooling and shaping effect of the fibers, and may even cause heat damage to the staff. Moreover, the aramid fibers in the high-temperature state are not easy to align and collect, increasing the operation difficulty and time cost of the staff. Therefore, an aramid fiber high-temperature crimping device is proposed. Summary of the Utility Model

[0022] Such as Figures 1 to 3As shown in the figure, an aramid fiber high-temperature curling device includes a curling machine 1 (the curling machine 1 is a prior art and will not be elaborated here). A guiding plate 2 is fixedly installed at the output end of the curling machine 1. A plurality of air-permeable holes 3 distributed in a rectangular array are formed in the top of the guiding plate 2. Two side plates 4 are arranged on the top of the guiding plate 2. A transmission component 5 for adjusting the distance between the two side plates 4 is arranged inside the guiding plate 2. Two U-shaped frames 6 are arranged above the guiding plate 2. U-shaped frames 7 are respectively arranged at positions corresponding to the two U-shaped frames 6 below the guiding plate 2. A fan 8 is arranged inside each U-shaped frame 6 and each U-shaped frame 7. A driving component 9 for driving the corresponding two fans 8 to move is arranged between each U-shaped frame 6 and the adjacent U-shaped frame 7. It should be noted that first, the transmission component 5 is controlled according to the width of the aramid fiber, so that the two side plates 4 approach or move away from each other. When the distance between the two side plates 4 is adjusted appropriately, it can guide aramid fibers of different widths to discharge. To cool the aramid fiber after high-temperature curling, two groups of driving components 9 are started while the aramid fiber discharges through the guiding plate 2, so that the two groups of driving components 9 can respectively drive the corresponding two driving components 9 to perform linear reciprocating motion. When every two adjacent driving components 9 move and are started, the aramid fiber is cooled simultaneously from the upper and lower sides by every two adjacent driving components 9. The cooled aramid fiber is convenient for workers to collect and can also assist in shaping.

[0023] As Figure 1 , Figure 3 As shown in the figure, the transmission component 5 includes a strip-shaped hole 501. A strip-shaped hole 501 is formed in the top of the guiding plate 2. A rotatable bidirectional screw 502 is movably installed inside the strip-shaped hole 501. Two movable blocks 503 are respectively threadedly connected to both ends of the bidirectional screw 502. The two movable blocks 503 are respectively fixedly connected to the two side plates 4. A handwheel 504 for driving the bidirectional screw 502 to rotate is movably installed on the side wall surface of the guiding plate 2. It should be noted that by rotating the handwheel 504, the bidirectional screw 502 can rotate reciprocally when the handwheel 504 rotates reciprocally. When the bidirectional screw 502 rotates reciprocally, the corresponding two movable blocks 503 can approach or move away from each other. When each movable block 503 moves, it can drive the corresponding side plate 4 to move synchronously, so as to make the two side plates 4 approach or move away from each other and adjust the distance between the two side plates 4 appropriately.

[0024] As Figure 1 , Figure 3As shown, the transmission assembly 5 further includes sliding grooves 505. Two sliding grooves 505 are provided at the top of the guiding plate 2. Two sliders 506 are fixedly installed at the bottom of each side plate 4. Each slider 506 is movably installed inside the adjacent sliding groove 505. It should be noted that when each side plate 4 moves, it will drive the two sliders 506 connected to it to slide in the corresponding sliding grooves 505 respectively. The movement trajectory of the side plate 4 can be restricted through the mutual cooperation of the sliding grooves 505 and the sliders 506.

[0025] As Figure 1 , Figure 2 shown, the driving assembly 9 includes strip-shaped grooves 901. Strip-shaped grooves 901 are provided on the inner side far from the guiding plate 2 of each U-shaped frame 6 and the adjacent U-shaped frame 7. A lead screw 902 is movably installed inside each strip-shaped groove 901. A moving block 903 is threadedly connected to each lead screw 902. Each moving block 903 is fixedly connected to the adjacent fan 8. A rotating shaft 904 coaxial with the adjacent lead screw 902 is movably installed on the side wall surface of each U-shaped frame 6 and the adjacent U-shaped frame 7. A first gear 905 is fixedly installed at the free end of each rotating shaft 904. A servo motor 906 is fixedly installed on the side wall surface of each U-shaped frame 6. The output end of each servo motor 906 is fixedly connected to a second gear 907. Each second gear 907 is meshed with the adjacent two first gears 905. It should be noted that after the servo motor 906 is started, it can drive the corresponding second gear 907 to rotate reciprocally. The reciprocal rotation of the second gear 907 can make the corresponding two first gears 905 rotate reciprocally. The rotation of each first gear 905 will drive the corresponding rotating shaft 904 and lead screw 902 to rotate. The reciprocal rotation of each lead screw 902 can make the corresponding moving block 903 move linearly in a reciprocating manner. The movement of each moving block 903 will drive the corresponding fan 8 to move synchronously, so as to effectively cool different positions of the aramid fiber by using the moving fan 8.

[0026] As Figure 1 , Figure 2 shown, C-shaped rods 10 are fixedly installed at both ends of each U-shaped frame 6. Each C-shaped rod 10 is fixedly connected to the adjacent U-shaped frame 7. Two bolts 11 are threadedly connected to the top and bottom of each C-shaped rod 10. Each C-shaped rod 10 is sleeved on the adjacent side of the guiding plate 2. It should be noted that by moving the U-shaped frame 6 to make the corresponding two C-shaped rods 10 move along the guiding plate 2, and then rotating each bolt 11 respectively, the position of the C-shaped rod 10 can be fixed, so as to adjust the positions of each U-shaped frame 6 and the adjacent U-shaped frame 7 according to the cooling requirements.

[0027] As Figure 1 , Figure 2As shown, limiting grooves 12 are formed on both side wall surfaces of the guiding plate 2. A limiting rod 13 is fixedly installed inside each C-shaped rod 10, and each limiting rod 13 is movably installed inside the adjacent limiting groove 12. It should be noted that when the C-shaped rod 10 moves along the guiding plate 2, the limiting rod 13 can slide inside the limiting groove 12. The movement trajectory of the C-shaped rod 10 can be restricted by the mutual cooperation of the limiting rod 13 and the limiting groove 12.

[0028] In summary:

[0029] First, control the transmission assembly 5 according to the width of the aramid fiber, so that the two side plates 4 approach or move away from each other. When the distance between the two side plates 4 is adjusted appropriately, it can be suitable for guiding aramid fibers of different widths to discharge. In order to cool the aramid fiber after high-temperature curling, start the two groups of driving assemblies 9 while the aramid fiber discharges through the guiding plate 2, so that the two groups of driving assemblies 9 can respectively drive the corresponding two driving assemblies 9 to perform linear reciprocating motion. When every two adjacent driving assemblies 9 move and start, cool the aramid fiber from the upper and lower sides simultaneously by using every two adjacent driving assemblies 9. The cooled aramid fiber can be conveniently collected by the staff and can also assist in shaping.
