[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 6 shown, a sisal combing device includes: a first support 1, a conveyor belt 2 is rotatably installed on the top of the first support 1, a spraying head 4 is fixedly installed on the top of the first support 1, a second support 5 is fixedly installed on one side of the first support 1, a third support 6 is fixedly installed on one side of the second support 5, a first motor 3 is fixedly installed on one side of the first support 1, and the output end of the first motor 3 is fixedly connected to the conveyor belt 2; a kneading assembly, which is fixedly installed on the top of the first support 1 and is used for kneading sisal fibers; a clamping and feeding assembly, which is installed on the tops of the second support 5 and the third support 6, two groups of clamping and feeding assemblies are symmetrically arranged on the second support 5, and two groups of clamping and feeding assemblies are symmetrically arranged on the third support 6, and the clamping and feeding assembly is used for transporting sisal fibers; a combing assembly, which is installed on the inner sides of both the second support 5 and the third support 6 and is used for combing sisal fibers.

[0027] The roughly beaten sisal fibers enter the kneading assembly through the conveyor belt 2 for kneading. After being kneaded, the hemp residues on the sisal fibers are loosened, and the loosened hemp residues can be more easily removed. After being kneaded, the sisal fibers pass through the spraying head 4 and are rinsed again to wash away the slurry on the sisal fibers, which can reduce the influence of the slurry on the sisal fibers. The rinsed sisal fibers are transported by the clamping and feeding assembly to the combing assembly. During the transportation process, the sisal fibers are combed by the continuously moving combing plate 22. The sisal fibers after kneading and cleaning are more convenient for removing hemp residues and combing. The combing assembly removes the hemp residues adhered to the sisal fibers. Since the used combing plate 22 can continuously comb the sisal fibers, the sisal fibers can be made more straight, improving the quality of sisal fiber combing.

[0028] As Figure 1 , Figure 5 and Figure 6 shown, the kneading assembly includes a fourth bracket 7 fixedly installed on the top of the first bracket 1. A first load-bearing rod 10 and a second load-bearing rod 11 are fixedly installed on the fourth bracket 7. The first load-bearing rod 10 and the second load-bearing rod 11 are arranged in parallel. Two groups of buffer rods 12 are hingedly installed on each of the first load-bearing rod 10 and the second load-bearing rod 11. The free ends of the buffer rods 12 are hingedly installed with a kneading frame 13. The kneading frame 13 is horizontally arranged. Springs are sleeved on the buffer rods 12. A curved convex platform is arranged at the bottom of the kneading frame 13. A bearing seat 8 is fixedly installed on the top of the first bracket 1. An eccentric wheel 9 is rotatably installed on one side of the bearing seat 8. A first connecting rod 14 is eccentrically hinged on one side of the eccentric wheel 9. The other side of the eccentric wheel 9 is connected to the output end of the first motor 3 through belt transmission. The end of the first connecting rod 14 is hingedly arranged with the kneading frame 13;

[0029] Through the transmission with the first motor 3, the eccentric wheel 9 starts to rotate, drives the kneading plate 15 to move back and forth in the way of a crank connecting rod. Through the arranged buffer rods 12, the kneading plate 15 can be pressed against the conveyor belt 2, and the sisal fibers are kneaded back and forth. The dregs on the sisal fibers are loosened in this process, and some sisal fibers adhered together are also kneaded apart, so that the sisal fibers can be more easily deburred and combed in the subsequent combing, reducing the probability of fiber damage during the combing process and improving the quality of the combed sisal fibers.

[0030] As Figure 1 , Figure 2 and Figure 3 shown, the pinch feeding assembly includes a first groove rail 24 fixedly installed on the top of the second bracket 5. A second groove rail 25 is fixedly installed on the top of the third bracket 6. A first conveyor chain 16 is rotatably installed on the top of the second bracket 5. A second conveyor chain 17 is rotatably installed on the top of the third bracket 6. A second motor 18 is fixedly installed on one side of the second bracket 5. The output end of the second motor 18 is fixedly connected to the first conveyor chain 16 and the second conveyor chain 17 through a rotating shaft. Block-shaped protrusions are arranged in an array on the chains of the first conveyor chain 16 and the second conveyor chain 17. Grooves are arranged at the tops of the first groove rail 24 and the second groove rail 25. The first conveyor chain 16 is located directly above the first groove rail 24. The second conveyor chain 17 is located directly above the second groove rail 25. The first groove rail 24 and the second groove rail 25 are arranged in parallel;

[0031] The washed sisal fibers are conveyed onto the first chute rail 24 and clamped by the first conveyor chain 16 to continue forward transportation. After being combed by a first combing assembly, the sisal fibers are conveyed above the second chute rail 25 and clamped by the second conveyor chain 17 to continue forward transportation. Through the combing of the second combing assembly, the areas that are clamped on the first conveyor chain 16 but not combed are combed. By setting the pinch roller assembly, it is convenient to comb the sisal fibers, resulting in good combing effect of the sisal fibers.

[0032] As Figure 1 , Figure 2 and Figure 4 shown, the combing assembly includes two groups of second connecting rods 20 rotatably installed on the inner walls of both sides of the third support 6. Two groups of third connecting rods 21 are hingedly installed on the inner walls of both sides of the third support 6. The end of the second connecting rod 20 is rotatably installed with a combing plate 22. The other end of the combing plate 22 is hingedly arranged with the third connecting rod 21. A plurality of sprockets 23 are rotatably installed on one side of the third support 6. The sprockets 23 are fixedly connected with the second connecting rods 20. The sprockets 23 are connected by a chain. A third motor 19 is fixedly installed on one side wall of the third support 6. The sprockets 23 and the third motor 19 are connected by a belt drive. The length of the third connecting rod 21 is longer than that of the second connecting rod 20. A number of needle-shaped comb teeth are arranged in an array on the upper surface of the combing plate 22;

[0033] When the sisal fibers are being transported in the pinch roller assembly, the third motor 19 drives the sprockets 23 to rotate and drives the second connecting rods 20 to rotate. Since a double-rocker mechanism is formed among the second connecting rods 20, the third connecting rods 21 and the combing plate 22, the combing plate 22 moves back and forth from bottom to top under the rotation of the second connecting rods 20 to remove the hemp residues mixed in the sisal fibers. At the same time, through two times of combing, the sisal fibers become straighter, improving the quality of the sisal fibers. The needle-shaped comb teeth arranged on the combing plate 22 do not prevent the pinch roller assembly from transporting the sisal fibers while combing the sisal fibers, making the combing effect better. Compared with the existing method of combing by hitting and colliding, this technology reduces the damage and breakage of the sisal fibers caused by hitting and colliding, making the sisal fibers have better toughness and improving the quality of the sisal fibers.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
