Description

Technical Field

[0001] This utility model relates to the field of composite fiber production technology, specifically a hot air drying device for composite fibers. Background Technology

[0002] Composite fiber is a type of multi-component fiber, a term used to describe various types of man-made fibers. It refers to fibers containing two or more non-mixed polymer fibers on the same cross-section. Composite fibers possess three-dimensional crimp, high bulkiness and coverage, good electrical conductivity, antistatic properties, and flame retardancy. They are mainly used in yarn, blankets, wool fabrics, thermal insulation fillings, silk fabrics, non-woven fabrics, medical and hygiene products, and special work clothes. Drying equipment is required during the production of composite fibers. However, current drying equipment typically uses a blower plate above the conveying composite fibers, preventing simultaneous vertical airflow for drying, resulting in poor drying efficiency. Furthermore, the winding rollers of the drying equipment are inconvenient to replace after winding the dried composite fibers, reducing work efficiency. Therefore, we propose a hot air drying device for composite fibers to solve these problems. Utility Model Content

[0021] 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.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention provides a hot air drying device for composite fibers, including a base plate 1, a drying chamber 2 fixed to the top of the base plate 1, an exhaust pipe 14 fixedly connected to the top of the drying chamber 2, and a filter screen 15 fixed inside the exhaust pipe 14 to facilitate the discharge of the hot air used inside the drying chamber 2. The filter screen 15 also serves to prevent dust. Openings are provided on both sides of the drying chamber 2, and two doors 3 are hinged to the front and back of the drying chamber 2 via pins. Each door 3 is equipped with... A viewing window facilitates observation of the interior of the drying oven 2, making it easier for staff to inspect the interior from the outside. Inside the drying oven 2, rotating shafts 4 are equidistantly connected via bearings. Dividing blocks 5 are equidistantly fixed to the surface of each rotating shaft 4. Six air blowing plates 6 are fixed inside the drying oven 2. A hot air blower 7 is fixed to the top of the base plate 1. A horizontal pipe 8 is fixedly connected to the outlet of the hot air blower 7, and three L-shaped pipes 9 are fixedly connected to the horizontal pipe 8. The air inlet pipes of the air blowing plates 6 slide through the drying oven. 2 extends to its exterior and is connected and fixed to the corresponding L-shaped tube 9. A support frame 10 is fixed on the top of the base plate 1. A roller 11 is placed on the top of the support frame 10. A drive mechanism 12 for driving the roller 11 to rotate is provided on the top of the base plate 1. When using this composite fiber hot air drying device, after placing it in a suitable position, one end of multiple composite fibers can be slid through the drying box 2 and fixed to the surface of the roller 11. When placing it, a single composite fiber can be placed on the dividing block 5 to facilitate the separation and conveying of multiple composite fiber lines and avoid their adhesion and aggregation. Then, the drive mechanism 12 is started to drive the roller 11 to rotate. After the roller 11 rotates, it can wind up the composite fiber. During the winding and moving of the composite fiber, the hot air fan 7 can be started. Then, the hot air fan 7 will send the hot air it blows out to the interior of the L-shaped tube 9 through the horizontal tube 8. Finally, it is sent to the blowing plate 6 through the L-shaped tube 9 to blow out. Thus, the upward and downward directions of the conveyed composite fiber can be blown at the same time to speed up the drying speed of the composite fiber.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the drive mechanism 12 includes two guide frames 1201 fixed to the top of the base plate 1. Each guide frame 1201 has a groove with two sliding blocks 1202 slidably connected within it. The sidewalls of each sliding block 1202 are rotatably connected to a rotating rod 1203 via bearings. A drive disc 1204 is fixed to the surface of each rotating rod 1203. Two driven discs 1211 are fixed to the surface of the roller body 11. Anti-slip rings 1212 are fixed to the surfaces of the four drive discs 1204 and the two driven discs 1211, allowing the drive discs 1204 to fit against the surfaces of the driven discs 1211. To facilitate better rotation of the roller 11, a U-shaped plate 1205 is installed between the inner walls of both sides of the support frame 10. Four connecting rods 1206 are rotatably connected to the top inner wall of the U-shaped plate 1205 via pins. The top ends of the connecting rods 1206 are rotatably connected to corresponding sliding blocks 1202 via pins. Two cylinders 1207 are fixed to the top of the base plate 1, and the ejector ends of the cylinders 1207 are fixedly connected to the bottom of the U-shaped plate 1205. Drive wheels 1208 are fixed to the surface of the rotating rod 1203, and two drive wheels 1208 on the same side are connected by a belt 120. 9. Transmission connection: Both sides of the U-shaped plate 1205 are rotatably connected to adjusting shafts 1210 via bearings. The adjusting shafts 1210 are respectively engaged with corresponding belts 1209. In use, the two cylinders 1207 are activated to drive the U-shaped plate 1205 to move downward. After the U-shaped plate 1205 moves downward, the sliding blocks 1202 on both sides can move simultaneously to the middle position under the cooperation of the connecting rod 1206. After the sliding blocks 1202 move, they will drive the driving disc 1204 to fit tightly with the driven disc 1211 on the roller body 11. Furthermore, when the U-shaped plate 1205 moves, it will drive the two adjusting shafts 1210. The downward movement allows for adjustment of the lengths of the two belts 1209, enabling a single motor to drive the two rotating rods 1203 on the same side to rotate synchronously. When the rotating rods 1203 rotate, they drive the drive disc 1204 to rotate, which in turn drives the driven disc 1211 to rotate. This, in turn, drives the roller 11 to rotate. Once the roller 11 is wound up, the cylinder 1207 is activated to push the U-shaped plate 1205 upward, separating the drive disc 1204 from the driven disc 1211. The roller 11 can then be removed for replacement.

[0025] like Figure 1 and Figure 3 As shown, in some embodiments, horizontal plates 13 are fixed at the openings on both sides of the drying chamber 2 to support the composite fibers. These plates support the composite fibers entering and exiting the drying chamber 2, facilitating the delivery of the composite fibers into the drying chamber 2 and their drying and subsequent transport out.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
