[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figures 1-4As shown in this embodiment, a continuous drying device for meta-aramid fibers includes a drying chamber 1. A mounting frame 2 is fixedly installed inside the drying chamber 1. Two sets of symmetrically distributed mounting rods 3 are rotatably mounted on the mounting frame 2. Two sets of symmetrically distributed first synchronous pulleys 4 are sleeved on each of the two sets of mounting rods 3. Two sets of symmetrically distributed first synchronous belts 5 are sleeved on each of the two sets of mounting rods 3. A first conveyor belt 6 is sleeved on the mounting rods 3. A fixing frame 7 is fixedly mounted on the first conveyor belt 6. A first clamping ring 8 is rotatably sleeved on the fixing frame 7. A second clamping ring 9 is rotatably sleeved on the fixing frame 7. The first clamping ring 8 and the second clamping ring 9 are symmetrically distributed. Multiple sets of symmetrically distributed torsion springs 10 are sleeved on the fixing frame 7. A movable frame 11 is slidably mounted on the movable frame 11, a slide 17 is slidably mounted on the slide 11, and a rotating frame 18 is rotatably mounted on the slide 17. Multiple sets of equidistantly distributed combing rods 19 are fixedly mounted on the rotating frame 18, each set corresponding to the first conveyor belt 6. A connecting rod 25 is rotatably mounted on the slide 17. A crank 26 is rotatably mounted inside the movable frame 11, and the crank 26 is rotatably connected to the end of the connecting rod 25 away from the slide 17 via a rotating shaft. Two sets of first synchronous belts 5 are respectively connected to two corresponding sets of first synchronous pulleys 4. Both sides of the first conveyor belt 6 are fixedly connected to the two sets of first synchronous belts 5. The two ends of the torsion spring 10 are respectively connected to the corresponding first clamping ring 8 or second clamping ring 9 and the fixed frame. 7. Fixed connection: A first slide rod 23 is fixedly installed on the movable frame 11. The slide frame 17 is slidably sleeved with the first slide rod 23. Two sets of symmetrically distributed first springs 24 are sleeved on the first slide rod 23. The two ends of the two sets of first springs 24 are fixedly connected to the slide frame 17 and the movable frame 11, respectively. By bending the first clamping ring 8 and the second clamping ring 9, the meta-aramid fibers waiting to be dried are placed between the first clamping ring 8 and the second clamping ring 9. When the first clamping ring 8 and the second clamping ring 9 are released, the first clamping ring 8 and the second clamping ring 9 close under the action of the torsion spring 10 to complete the clamping and fixing of the meta-aramid fibers. The motor on the mounting frame 2 drives the mounting rod 3 to rotate, which, together with the first synchronous pulley 4 and the first synchronous belt 5, makes the first conveyor belt 6 rotate. The upper fixed frame 7 and the meta-aramid fibers fixed on the fixed frame 7 are conveyed at a uniform speed. Simultaneously, the first cylinder 12 is started to drive the moving frame 11 to move down until the carding rod 19 on the moving frame 11 is in contact with the surface of the first conveyor belt 6. The motor on the moving frame 11 drives the crank 26 to rotate. With the help of the connecting rod 25, the slide 17 drives the rotating frame 18 and the multiple sets of carding rods 19 distributed at equal intervals on the rotating frame 18 to reciprocate linearly on the surface of the moving frame 11 and the first conveyor belt 6. With the help of the first conveyor belt 6, multiple sets of meta-aramid fibers move forward at a uniform speed to complete the carding of the meta-aramid fibers, so as to avoid the fibers from tangling and knotting, which would affect the drying effect of the meta-aramid fibers wrapped inside and the overall drying efficiency.
[0025] like Figure 5 and Figure 6As shown, a gear 20 is sleeved on the rotating frame 18, a rack 21 is slidably installed inside the slide 17, a second cylinder 22 is fixedly installed inside the rotating frame 18, the rack 21 is fixedly connected to the output end of the piston rod of the second cylinder 22, and the rack 21 meshes with the gear 20. A roller brush 27 is rotatably installed on the moving frame 11, and the roller brush 27 is correspondingly set with the combing rod 19 on the rotating frame 18. A scraper brush 28 is slidably installed on the moving frame 11, and the scraper brush 28 is fitted with the roller brush 27. A second slide rod 29 is fixedly installed on the moving frame 11, a cam 32 is rotatably installed on the moving frame 11, and a slider 31 is fixedly installed on the scraper brush 28. The slider 31 and... The second slide rod 29 is slidably sleeved, and two sets of symmetrically distributed second springs 30 are sleeved on the second slide rod 29. The two ends of the two sets of second springs 30 are fixedly connected to the slider 31 and the moving frame 11, respectively. The cam 32 is fitted against the slider 31. Two sets of symmetrically distributed first cylinders 12 are fixedly mounted on the mounting frame 2. The moving frame 11 is fixedly connected to the output end of the piston rod of the first cylinder 12. Two sets of symmetrically distributed first rotating rods 13 are rotatably mounted on the moving frame 11. Two sets of symmetrically distributed second synchronous pulleys 14 are sleeved on each of the two sets of first rotating rods 13. Two sets of symmetrically distributed second synchronous belts 15 are sleeved on each of the two sets of first rotating rods 13. Each rod 13 is fitted with a second conveyor belt 16. Two sets of second synchronous belts 15 are respectively connected to two sets of second synchronous pulleys 14 for transmission. The two sides of the second conveyor belt 16 are respectively fixedly connected to the two sets of second synchronous belts 15. The second conveyor belt 16 is located below the roller brush 27 and the scraper brush 28. After the combing rod 19 on one side of the rotating frame 18 has been used for a period of time, the second cylinder 22 in the slide 17 is activated to drive the rack 21 to slide. In conjunction with the gear 20, the rotating frame 18 drives the combing rod 19 to rotate. The used combing rod 19 corresponds to the roller brush 27. The motor on the moving frame 11 drives the roller brush 27 to rotate, completing the winding on the corresponding combing rod 19. During fiber cleaning, the cleaned fibers adhere to the roller brush 27. As the motor on the moving frame 11 drives the cam 32 to rotate, the cam 32 pushes the slider 31 that is in contact with it. The slider 31 slides on the second slide rod 29 and squeezes or stretches the second spring 30. Therefore, in conjunction with the second spring 30, the slider 31 drives the scraper 28 to move back and forth on the moving frame 11, repeatedly brushing the roller brush 27. The fibers adhering to the roller brush 27 fall onto the second conveyor belt 16 below, and the second conveyor belt 16 transports the cleaned fibers out of the drying box 1 for easy cleaning by the staff.
[0026] This utility model provides a continuous drying device for meta-aramid fibers. The specific working principle is as follows: By bending the first clamping ring 8 and the second clamping ring 9, the meta-aramid fibers awaiting drying are placed between the first clamping ring 8 and the second clamping ring 9. Loosening the first clamping ring 8 and the second clamping ring 9 causes the first clamping ring 8 and the second clamping ring 9 to close under the action of the torsion spring 10, thus clamping and fixing the meta-aramid fibers. The motor on the mounting frame 2 drives the mounting rod 3 to rotate, which, in conjunction with the first synchronous pulley 4 and the first synchronous belt 5, causes the first conveyor belt 6 to drive the upper fixed frame 7 and the fixed... The meta-aramid fibers, fixed on the fixed frame 7, are conveyed at a uniform speed. Simultaneously, the first cylinder 12 is activated, causing the moving frame 11 to move downwards until the carding rods 19 on the moving frame 11 are in contact with the surface of the first conveyor belt 6. The motor on the moving frame 11 drives the crank 26 to rotate, which, in conjunction with the connecting rod 25, causes the slide 17 to drive the rotating frame 18 and multiple sets of equidistantly distributed carding rods 19 on the rotating frame 18 to reciprocate linearly on the moving frame 11 and the surface of the first conveyor belt 6. This, combined with the first conveyor belt 6, causes multiple sets of meta-aramid fibers to move forward at a uniform speed, completing the carding of the meta-aramid fibers and preventing… The fibers become entangled and knotted, affecting the drying effect of the meta-aramid fibers encased inside and the overall drying efficiency. After a period of use, the second cylinder 22 inside the slide 17 activates, driving the rack 21 to slide. This, in conjunction with the gear 20, causes the rotating frame 18 to rotate the carding rod 19. The used carding rod 19 corresponds to the roller brush 27. The motor on the moving frame 11 drives the roller brush 27 to rotate, completing the cleaning of the fibers entangled on the corresponding carding rod 19. The cleaned fibers adhere to the roller brush 27, while the moving frame 1... During the rotation of cam 32 driven by the motor, cam 32 pushes the slider 31 that is in contact with it. The slider 31 slides on the second slide rod 29 and squeezes or stretches the second spring 30. Therefore, in conjunction with the second spring 30, the slider 31 drives the scraper 28 to move back and forth on the moving frame 11, repeatedly brushing the roller brush 27 that is in contact with it. The fibers adhering to the roller brush 27 fall onto the second conveyor belt 16 below, and the second conveyor belt 16 transports the cleaned fibers out of the drying box 1 for easy cleaning by the staff.
