Description

Technical Field

[0001] This utility model relates to the field of microfiber processing technology, specifically to a microfiber rapid drying device. Background Technology

[0002] Rapid drying equipment for microfiber is a key piece of equipment used for dehydrating and drying microfiber materials, and its performance directly affects the physical properties of the fibers and production efficiency. In modern industrial production, microfiber, with its high water absorption, strong detergency, and soft and delicate touch, is widely used in cleaning products, high-end clothing fabrics, filter materials, and many other fields. As market demands for the quality and production capacity of microfiber products continue to rise, the technological level of the drying process has become a crucial factor restricting the industry's development.

[0003] However, existing drying equipment mostly employs single-sided hot air jetting or static drying methods, resulting in microfibers being heated only on one side during the drying process. This leads to significant differences in moisture content between the inside and outside of the fiber. This uneven drying effect not only severely affects fiber quality but can also cause fiber deformation and embrittlement, reducing the finished product qualification rate. Simultaneously, static drying methods have low heat exchange efficiency, significantly extending the drying cycle and failing to meet the needs of enterprises for high-efficiency production. To address these issues, there is an urgent need for innovative designs based on existing microfiber rapid drying equipment to improve drying quality and production efficiency, thereby promoting the high-quality development of the microfiber industry.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a rapid drying device for microfiber, including a drying box 1 and a movable ring 4. A fixed ring 3 is provided in the middle of the drying box 1, and a support plate 2 is fixed at the top and bottom of the fixed ring 3. The end of the support plate 2 is fixedly connected to the inner wall of the drying box 1. An annular cavity 5 is opened inside the side of the movable ring 4, and an air outlet 6 is opened inside the annular cavity 5. The air outlet 6 is evenly distributed inside the movable ring 4. An annular groove 7 is opened in the middle of the outer side of the annular cavity 5. The interior of the fixed ring 3 is rotatably connected to the middle of the outer side of the movable ring 4 through a sealed bearing. The annular groove 7 is located inside the fixed ring 3. An air supply mechanism is provided on the fixed ring 3, and a driving mechanism is provided on the movable ring 4.

[0022] The movable rings 4 are evenly distributed inside the drying chamber 1, which facilitates the fibers to pass through the inside of the movable rings 4 and allows the fibers to be dried over long distances and multiple times, thus improving the fiber drying effect.

[0023] The air supply mechanism includes an air supply pipe 9. The air supply pipe 9 is fixed inside the drying chamber 1, and one end of the air supply pipe 9 passes through the end of the drying chamber 1 and is located outside the drying chamber 1. The other end of the air supply pipe 9 is connected to the outlet pipe of the external hot air blower. The end of the hot air blower inlet pipe is fixed with a filter screen by bolts. A connecting pipe 8 is fixed to one side of the air supply pipe 9, and one end of the connecting pipe 8 is fixedly connected to the middle of the fixed ring 3. The connecting pipe 8 is interconnected with the air supply pipe 9 and the annular groove 7. The connecting pipes 8 are evenly distributed on the air supply pipe 9. The filter screen of the hot air blower inlet pipe can effectively intercept dust, impurities and other foreign objects in the air, preventing them from entering the drying chamber 1 through the air supply pipe 9 and contaminating the microfiber. The evenly distributed connecting pipes 8 ensure that the hot air can be evenly delivered to the annular groove 7 of each fixed ring 3, and then evenly sprayed onto the surface of the microfiber through the annular cavity 5 and the air outlet 6 of the movable ring 4, improving the heat exchange efficiency and accelerating the drying process.

[0024] The drive mechanism includes a shaft 10, a support plate 2, and a drying chamber 1. The shaft 10 is rotatably mounted between the support plate 2 and the drying chamber 1 via a sealed bearing. The outer wall of the shaft 10 is nested with equal-spaced first gears 11, and the bottom of the first gear 11 meshes with the top of the second gear 12. The inner wall of the second gear 12 is fixedly connected to the outer wall of the movable ring 4. Meanwhile, the end of the shaft 10 passes through the end of the drying chamber 1 and is fixedly connected to the output end of the servo motor 13. The outer wall of the servo motor 13 is fixed to the outer wall of the drying chamber 1 via a mounting plate. By starting the servo motor 13, the movable ring 4 can be rotated.

[0025] Both ends of the drying chamber 1 are provided with inlet and outlet holes 14, and the central axis of the inlet and outlet holes 14 coincides with the central axis of the movable ring 4. This design ensures that the microfiber is accurately oriented when entering and exiting the drying chamber 1, and can pass smoothly through the central area of ​​the movable ring 4, reducing the offset and friction between the fiber and the inner wall of the drying chamber 1 or the edge of the movable ring 4, and reducing the risk of fiber damage.

[0026] A rectangular through groove 16 is provided on the front side of the drying box 1, and a sealing door 15 is provided on the outer side of the drying box 1 in front of the rectangular through groove 16. The sealing door 15 is existing technology and can be opened and closed normally, and fibers can be installed through the rectangular through groove 16.

[0027] The drying chamber 1 is equipped with an exhaust pipe 17 at its end, and the drying chamber 1 and the exhaust pipe 17 are connected to each other. The end of the exhaust pipe 17 is fitted with a filter screen by bolts. The exhaust pipe 17 can discharge the hot and humid air generated during the drying process in a timely manner, so as to avoid the accumulation of hot and humid air in the drying chamber 1, which would lead to increased humidity and affect drying efficiency and quality.

[0028] Working principle: First, connect both ends of the microfiber roll to the unwinding and rewinding devices respectively, so that the fiber passes through the inlet and outlet holes 14 at both ends of the drying chamber 1 and passes through the interior of each movable ring 4 in sequence. Since the movable rings 4 are evenly distributed in the drying chamber 1, it is convenient for the fiber to pass through the interior of the movable rings 4.

[0029] The servo motor 13 is started, and its output drives the shaft 10 to rotate. The shaft 10, through the meshing of the first gear 11 and the second gear 12, drives the movable ring 4 to rotate uniformly within the fixed ring 3. Simultaneously, the hot air blower delivers heated air through the air supply pipe 9 and connecting pipe 8 to the annular groove 7 of the fixed ring 3, then into the annular cavity 5 of the movable ring 4, and finally sprays it evenly from the inner air outlet 6, forming a hot air field surrounding the microfiber. The rotation of the movable ring 4 causes the hot air to contact the fiber in a dynamic spiral path, achieving not only uniform heating from all sides but also accelerating the evaporation of moisture from the fiber surface through airflow shear force.

[0030] The hot and humid air generated during the drying process is discharged through exhaust pipe 17.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
