Description

Technical Field

[0001] This utility model relates to the field of fiber processing technology, and in particular to a high-quality three-dimensional crimped short fiber shaping device. Background Technology

[0002] With the development of science and technology and industry, the demand for high-performance short fibers in aerospace, automotive, electronics and other fields is constantly increasing. This requires that special cooling and shaping technology be used in the production process of short fibers to achieve the unique properties and morphology of the fibers. The common method is to place the crimped short fibers in hot air, use the heat of the hot air to intensify the movement of molecular chain segments in the fibers, eliminate internal stress, and then cool them in the subsequent process to further adjust the crimped shape of the fibers and then fix them.

[0003] Chinese Patent 201921499687.2 discloses a fiber production equipment for uniformly spraying antistatic agent, including a frame, a turning mechanism, a spraying mechanism, a front transmission mechanism, a rear transmission mechanism, and a oscillation mechanism. By setting a turning mechanism below the spraying mechanism, the fibers to be processed are transported by the front transmission mechanism and fall onto the elastic surface of the turning mechanism. The elastic surface vibrates up and down under the drive of the drive component, so that the fibers on it are continuously turned and vibrated, so that the short fibers can be finely adjusted in terms of curling during the turning process and heat dissipation and shaping can be accelerated.

[0004] However, this technical solution has the following problems: it is in a state of natural heat dissipation during the turning process, which is slow and the effect of fine-tuning the short fiber curl is not good. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-quality three-dimensional crimped short fiber setting device. By setting up a cooling zone, a tossing mechanism in the cooling zone to tosses the short fibers on the conveyor belt to adjust the degree of crimping. At the same time, the cooling pipes provide air cooling for the short fibers to accelerate cooling and assist in rapid setting after adjustment, making the crimping of the short fibers more uniform and stable, improving work efficiency, and facilitating subsequent packaging and storage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-quality three-dimensional crimped short fiber setting device, comprising a frame, a conveyor belt on the frame, a cooling zone on the frame, the cooling zone including a turning mechanism that turns the short fibers on the conveyor belt to adjust the crimp degree, and a cooling pipe; the cooling pipe cools and sets the adjusted short fibers by blowing cold air.

[0007] As an improvement, the actuating mechanism includes a rotating shaft rotatably mounted on a frame; the rotating shaft is provided with a plurality of sets of rake teeth, each set of rake teeth being evenly distributed along the axial direction of the rotating shaft.

[0008] As an improvement, the rake teeth are provided in at least two sets, and the ends of the rake teeth are inclined.

[0009] As an improvement, the cooling pipe is provided with an array of several air outlets, and the openings of the air outlets are vertically downward.

[0010] As an improvement, the conveyor belt in the cooling zone is recessed and covered with a limiting block.

[0011] As an improvement, the limiting block has a mounting groove in the middle, and the cooling pipe is embedded in the mounting groove.

[0012] As an improvement, the bottom of the limiting block on the output side is provided with an inclined surface, which is inclined downward along the conveying direction of the conveyor belt.

[0013] As an improvement, a number of spraying mechanisms are provided on one side of the input end of the limiting block.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model is equipped with a cooling zone. After adjusting the degree of curl by moving the short fiber through the moving mechanism, it is air-cooled to quickly dissipate heat and shape the fiber, making the curl of the short fiber more uniform and stable, ensuring the quality of the short fiber, and also improving the cooling efficiency.

[0016] (2) This utility model provides a recessed setting in the conveyor belt in the cooling zone and covers it with a limiting block to limit and protect the short fibers during the process of moving and blowing air, preventing the short fibers from falling out of the conveyor belt and facilitating subsequent collection and transfer.

[0017] (3) By setting an inclined surface on the limiting block, the present invention sorts and compresses the messy short fibers after being moved and blown from the cooling zone, reduces the stacking height of the short fibers on the conveyor belt, and facilitates subsequent packaging and storage operations.

[0018] In summary, this utility model has the advantages of high product quality, fast cooling and shaping, and convenient warehouse logistics. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] Example 1

[0027] like Figures 1 to 4 As shown, this embodiment provides a high-quality three-dimensional crimped short fiber shaping device, including a frame 1, a conveyor belt 2 on the frame 1, a cooling zone 3 on the frame 1, the cooling zone 3 including a turning mechanism 31, the turning mechanism 31 turning the short fibers on the conveyor belt 2 to adjust the crimp degree, and a cooling pipe 32; the cooling pipe 32 cools and shapes the adjusted short fibers by blowing cold air.

[0028] like Figure 2 As shown, the actuating mechanism 31 includes a rotating shaft 311 rotatably mounted on the frame 1; the rotating shaft 311 is provided with a plurality of sets of rake teeth 312, and each set of rake teeth 312 is evenly distributed along the axial direction of the rotating shaft 311.

[0029] It is worth mentioning that proper manipulation can fine-tune the crimp of short fibers, making the crimp more uniform, stable, and in line with requirements. For crimped short fibers, a good crimp effect is crucial for their bulkiness, elasticity, and cohesion. Manipulation helps to further optimize these properties.

[0030] like Figure 2 As shown, at least two sets of rake teeth 312 are provided, and the ends of the rake teeth 312 are inclined.

[0031] Specifically, since the rotation speed of the shaft 311 should not be too fast, two or more sets of rake teeth 312 can ensure that the short fibers can be more fully moved during the conveying process, and the ends of the rake teeth 312 are tilted in the opposite direction of rotation, so that the short fibers are not easily damaged during the moving process.

[0032] like Figure 4 As shown, the cooling pipe 32 is provided with a plurality of air outlets 321 arranged in an array, and the openings of the air outlets 321 are vertically downward.

[0033] Here, the vertical downward direction allows the airflow to act vertically and evenly on the short fibers, providing a more comprehensive and balanced coverage. The airflow direction is consistent with the direction of gravity, allowing the airflow to flow more stably without other external interference, reducing airflow turbulence and fluctuations.

[0034] like Figure 2 As shown, the conveyor belt 2 in the cooling zone 3 is recessed and covered with a limiting block 4.

[0035] Understandably, the recess is designed to provide sufficient installation space for the actuating mechanism 31. During the actuation and blowing process, the short fibers are protected by the limiting block 4 and will not fall out of the range of the conveyor belt 2.

[0036] like Figure 4 As shown, the limiting block 4 has an installation groove 41 in the middle, and the cooling pipe 32 is embedded in the installation groove 41.

[0037] Combination Figure 3 This facilitates the disassembly and installation of the cooling pipe 32. During operation, it is unavoidable that the air outlet 321 may become blocked. Operators can quickly remove the cooling pipe 32 from the limiting block 4 for cleaning and unblocking.

[0038] like Figure 2 As shown, the bottom of the limiting block 4 on the output end side is provided with an inclined surface 42, which is inclined downward along the conveying direction of the conveyor belt 2.

[0039] To ensure that the messy short fibers after being tossed and blown from cooling zone 3 are sorted and compressed, reducing the stacking height of short fibers on the conveyor belt, and facilitating subsequent packaging and storage.

[0040] like Figure 1 As shown, a number of spraying mechanisms 5 are provided on one side of the input end of the limiting block 4.

[0041] It should be noted that short fibers are prone to static electricity, which can be effectively avoided by spraying an antistatic agent. A spraying mechanism 5 is set at the input end. After the short fibers are sprayed, they enter the cooling zone 3 and are stirred and blown to make the short fibers more evenly coated.

[0042] Work steps

[0043] Short fibers are conveyed on conveyor belt 2 and sprayed with antistatic agent by spraying mechanism 5 before reaching the input end of limit block 4. They continue to be conveyed to cooling zone 3, where conveyor belt 2 is concave. The short fibers are turned over by the agitator inside and adjusted for curling. At the same time, they are assisted in shaping by the cold air blown from the top cooling pipe and the antistatic agent is evenly applied to the surface of the short fibers. When conveyed to the output of limit block 4, the short fibers are briefly affected by the inclined surface, which sorts and compresses the short fibers for easy subsequent packaging and storage.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
