Description
Technical Field
[0001] This utility model relates to the technical field of short fiber processing equipment, specifically a cotton and polyester short fiber processing equipment. Background Technology
[0002] Short fiber processing involves processing cotton or polyester raw materials into short fibers for the production of textiles, nonwovens, thermoplastic composites, etc. Due to its high strength, good abrasion resistance, good light resistance, and low price, the market has grown rapidly, and its application has expanded from daily use to even military industry. Today, it has become an important raw material for the textile, clothing, and home textile industries.
[0003] Existing short fiber processing equipment typically stretches cotton or molten polyester into filaments through rotation, then cools and solidifies them into solid fibers. These continuous fibers are then cut to the desired length to obtain the short fibers. However, short fibers produced in this way are prone to breakage during crimping and stretching due to insufficient pretension, significantly impacting product quality and reducing production efficiency. Utility Model Content

The cutting box is equipped with a cutting device. A first connecting channel is provided between the cutting box and the constant temperature and humidity chamber. A bundling frame is provided inside the constant temperature and humidity chamber. An operation panel is provided on the outer surface of the constant temperature and humidity chamber. A second connecting channel is provided between the constant temperature and humidity chamber and the tension heat setting machine. The guide roller group is located between the tension heat setting machine and the relaxation heat setting machine. The winding roller group is located on the side of the relaxation heat setting machine away from the tension heat setting machine.
[0006] As a preferred embodiment, the cutting device includes a cutting blade and a cutting shaft, the cutting shaft being rotatably mounted on the inner wall of the cutting box, and the cutting blade being mounted on the outer wall of the cutting shaft.
[0007] As a preferred embodiment, the guide roller assembly includes a first guide roller, a second guide roller, and a third guide roller, wherein the third guide roller is disposed between the first guide roller and the second guide roller, and the third guide roller is staggered from the first guide roller and the second guide roller.
[0008] As a preferred embodiment, a pressure roller is provided below the first and second guide rollers and above the third guide roller, and a rubber ring is fitted on the outer wall of the pressure roller.
[0009] As a preferred embodiment, a conveyor belt is provided between the second guide roller and the relaxation heat setting machine.

Subsequently, a tension heat setter is used to stretch the fiber bundle, further increasing the pretension. The fiber bundle is then dried and subjected to tension heat set. The stretched fiber bundle is then conveyed to a relaxation heat setter via a guide roller assembly. Heat is used to eliminate the internal stress generated during the stretching process, causing the macromolecules to relax to a certain extent, thus fixing the shape of the woven fibers. Finally, the fibers are wound up by a take-up roller assembly, completing the short fiber processing. The short fibers processed by the above devices, with sufficient pretension applied to the fiber bundle by the constant temperature and humidity chamber and the tension heat setter, combined with the heat in the relaxation heat setter to eliminate the internal stress generated during the stretching process, greatly reduce breakage during the short fiber curling process, improving production efficiency.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific embodiments.
[0024] like Figure 1-4 As shown, this utility model embodiment provides a cotton and polyester staple fiber processing equipment, including a silo plate 1 and a staple fiber processing device installed on one side of the silo plate 1. The staple fiber processing device includes a cutting box 2, a constant temperature and humidity chamber 3, a tension heat setting machine 4, a guide roller group 5, a relaxation heat setting machine 7, and a winding roller group 9. The cutting box 2 is equipped with a cutting device. A first connecting channel 24 is provided between the cutting box 2 and the constant temperature and humidity chamber 3. A bundling frame 32 is provided inside the constant temperature and humidity chamber 3. An operation panel 33 is provided on the outer surface of the constant temperature and humidity chamber 3. A second connecting channel 31 is provided between the constant temperature and humidity chamber 3 and the tension heat setting machine 4. The guide roller group 5 is located between the tension heat setting machine 4 and the relaxation heat setting machine 7. The winding roller group 9 is located on the side of the relaxation heat setting machine 7 away from the tension heat setting machine 4.
[0025] The storage chamber 1 houses the short fiber processing device, while the cutting device in the cutting box 2 cuts the nascent fibers to obtain shorter nascent fibers. These short nascent fibers are then fed into the constant temperature and humidity chamber 3 via the first connecting channel 24. The bundling rack 32 within the chamber 3 is used to bundle the nascent fibers into filaments. Before bundling, the operating panel 33 adjusts the temperature and humidity within the chamber 3 to maintain a constant temperature and humidity environment. The nascent fibers are stored in this environment for a period before bundling, applying a certain pre-tension to increase their tensile strength. To further increase the pre-tension, the bundled filaments are fed into the tension heat setting machine 4 via the second connecting channel 31. The tensioning heat setter 4 stretches the filament bundle to further increase its pretension, and then dries and heat-sets it. The guide roller group 5 is used for directional transmission of the filament bundle. The filament bundle stretched by the tensioning heat setter is then transported to the relaxation heat setter 7 via the guide roller group 5. The heat in the relaxation heat setter 7 eliminates the internal stress generated during the stretching process, causing the macromolecules to relax to a certain extent, thus fixing the shape of the braided filament bundle and generating short fibers. Finally, the short fibers are wound up by the take-up roller group 9 to complete the short fiber processing. After processing by the above devices, the short fibers are subjected to sufficient pretension by the constant temperature and humidity chamber 3 and the tensioning heat setter 5. Combined with the relaxation heat setter 7 to eliminate the internal stress generated during the stretching process, this greatly reduces the breakage of short fibers during the winding process and improves production efficiency.
[0026] like Figure 2As shown, the cutting device includes a cutting blade 21 and a cutting shaft 22. The cutting shaft 22 is rotatably mounted on the inner wall of the cutting box 2, and the cutting blade 21 is mounted on the outer wall of the cutting shaft 22. By setting the cutting blade 21 and the cutting shaft 22 inside the cutting box 2, in order to obtain shorter nascent fibers, cotton or polyester nascent fibers are placed inside the cutting box 2, and the rotation of the cutting shaft 22 drives the cutting blade 21 to cut the nascent fibers.
[0027] like Figure 4 As shown, the guide roller group 5 includes a first guide roller 51, a second guide roller 52, and a third guide roller 53. The third guide roller 53 is disposed between the first guide roller 51 and the second guide roller 52, and is staggered from the first guide roller 51 and the second guide roller 52. The bundle of fibers extruded in the tension heat setter 4 winds out from below the first guide roller 51, then winds around above the third guide roller 53, and passes through below the second guide roller 52. Finally, it is wound up by the take-up roller group 9. The function of the guide roller group 5 is to guide the short fibers. In the process of guiding the short fibers, it also plays a role in tensioning the short fibers, which facilitates the take-up roller 9 to bundle the short fibers.
[0028] like Figure 4 As shown, a pressure roller 6 is provided below the first guide roller 51 and the second guide roller 52 and above the third guide roller 53. A rubber ring 61 is fitted on the outer wall of the pressure roller 6. By providing the pressure roller 6 below the first guide roller 51 and the second guide roller 52 and above the third guide roller 53, slippage of the filament bundle during the guiding process is prevented, the tensile strength of the filament is improved, and the tensile ratio is guaranteed. The rubber ring 61 can be made of polyurethane rubber to improve the grip on the filament bundle and further reduce slippage.
[0029] like Figure 2 and Figure 4 As shown, a conveyor belt 71 is provided between the second guide roller 52 and the relaxation heat setting machine 7. One end of the conveyor belt 71 corresponds to the second guide roller 52. A transport channel is provided inside the relaxation heat setting machine 7. The end of the conveyor belt 71 away from the second guide roller 52 passes through the transport channel. Rollers 72 are rotatably installed at both ends of the conveyor belt 71. The through transport channel inside the relaxation heat setting machine 7 facilitates the conveyor belt 71 to transport and output the filament bundles. The filament bundles output from the second guide roller 52 are transported into the relaxation heat setting machine 7. After the shape of the braided yarn is fixed, the conveyor belt 71 transports the fixed short fibers out of the relaxation heat setting machine 7. The rotation of the rollers 72 drives the conveyor belt 71 to operate, thereby realizing the transport of short fibers.
[0030] like Figure 1As shown, a limiting roller group 8 is provided between the transmission belt 71 and the take-up roller 9, and the end of the transmission belt 71 away from the second guide roller 52 corresponds to the limiting roller group 8. By providing the limiting roller group 8, the short fibers conveyed by the transmission belt 71 are transported to the take-up roller 9 for winding.
[0031] like Figure 3 As shown, a driving device is provided on the back of the bin plate 1. The driving device includes a first motor 23, a second motor 54, and a third motor 73. The first motor 23 is connected to the cutting shaft 22, the second motor 54 is connected to the guide roller group 5 and the pressure roller 6, and there are two third motors 73, which are connected to the roller 72. The driving device is used to drive each motor. The first motor 23 drives the cutting shaft 22 to rotate, which is used to cut the nascent fibers. The second motor 54 is used to drive the guide roller group 5 and the pressure roller 6 to start, guiding and stretching the bundled fibers. The third motor 73 is used to drive the roller 72 to provide power, so that the conveyor belt 71 can transport the bundled fibers.
[0032] The working principle of this embodiment is as follows: Nascent fibers are placed into the cutting box 2, and the cutting blade 21 is used to cut the nascent fibers, resulting in shorter nascent fibers. These short nascent fibers are then introduced into the constant temperature and humidity chamber 3 via the first connecting channel 24. The bundling frame 32 within the constant temperature and humidity chamber 3 is used to bundle the nascent fibers into filaments. Before bundling, the operating panel 33 adjusts the temperature and humidity within the constant temperature and humidity chamber 3 to maintain a constant temperature and humidity environment. The nascent fibers are stored in this constant temperature and humidity environment for a period of time before bundling. Applying a certain pre-tension to the nascent fibers increases their tensile strength. To further increase the pre-tension of the filaments, the bundled filaments are introduced into the tension heat setting machine 4 via the second connecting channel 31. The tension heat setting machine 4 then stretches the filaments. The pretension of the filament bundle is increased in one step, and the filament bundle is dried and subjected to tension heat setting. The guide roller group 5 is used for directional transmission of the bundle. The filament bundle stretched by the tension heat setting machine is then transported to the relaxation heat setting machine 7 via the guide roller group 5 and the conveyor belt 71. The heat in the relaxation heat setting machine 7 eliminates the internal stress generated in the bundle during the stretching process, and the macromolecules relax to a certain extent, so that the shape of the braided bundle is fixed and formed, generating short fibers. Then, it is transported to the take-up roller group 9 via the conveyor belt 71 and the limiting roller group 8. The take-up roller group 9 winds up the short fibers to complete the short fiber processing. After the short fibers are processed by the above devices, the constant temperature and humidity chamber 3 and the tension heat setting machine 5 apply sufficient pretension to the filament bundle. In addition, the relaxation heat setting machine 7 eliminates the internal stress generated in the stretching process, which greatly reduces the breakage of short fibers during the winding process and improves production efficiency.
