[0018] 1. The present invention arranges a movable component. When the PA needs to be air-dried, the PA is first placed in a containing frame. The air dryer is started and hot air is discharged from the air outlet through the first air duct and the second air duct. The PA in the containing frame is air-dried. At the same time, the threaded rod can be driven to rotate by starting a motor. The rotation of the threaded rod drives the moving rod to move back and forth. The movement of the moving rod drives the movement of the connecting rod. The movement of the connecting rod drives the movement of the stirring roller, so that the stirring roller pushes the PA in the containing frame to prevent the accumulation of the PA during the air-drying process. The current air-drying device mainly relies on the air dryer to achieve drying by blowing hot air to the PA material. Since the hot air outlet range of the device is small, the contact area between the PA and the hot air is limited, resulting in low air-drying efficiency. The air-drying efficiency of the device is improved.

[0019] 2. The present invention provides a first rotating assembly. When the connecting rod moves in the main body of the air-drying device, the movement of the connecting rod drives the movement of the connecting shaft, and the movement of the connecting shaft drives the movement of the first gear. The first gear meshes with the first rack plate and rotates. The rotation of the first gear drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the third bevel gear. The rotation of the third bevel gear drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the stirring roller. The rotation of the stirring roller drives the rotation of the stirring rod, thereby stirring the PA in the accommodating frame, causing the PA particles or materials to continuously flip in the accommodating frame, increasing the contact area with the flowing air, thereby accelerating the evaporation rate of water and further improving the air-drying efficiency of the device.

[0020] 3. The present invention provides a second rotating component. When the PA needs to be air-dried, the containing frame is slid into the main body of the air-drying device, so that the containing frame is pushed into the main body of the air-drying device. When the side wall of the containing frame contacts the protrusion, the protrusion is pushed to slide into the main body of the air-drying device. The movement of the protrusion drives the movement of the connecting plate. The movement of the connecting plate drives the movement of the second rack plate. The movement of the second rack plate drives the rotation of the second gear. The rotation of the second gear drives the fourth rotating shaft to rotate through the transmission component. The rotation of the fourth rotating shaft drives the rotation of the connecting rod. The connecting rod drives the stirring roller to rotate downward into the containing frame.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 12 As shown, in an embodiment of the present invention, a PA66 pre-processing air-drying device comprises an air-drying device body 1, a protective door 2 is hinged on one side of the air-drying device body 1, a containing frame 3 is slidably installed inside the air-drying device body 1, a first air duct 4 is installed inside the air-drying device body 1, a second air duct 5 is fixedly connected to one end of the first air duct 4, an air outlet 6 is fixedly installed at the bottom end of the second air duct 5, the air outlet 6 is arranged above the containing frame 3, and a moving component is arranged inside the containing frame 3;

[0036] The moving component includes a connecting rod 10 arranged inside the accommodating frame 3, and stirring rollers 12 are arranged on both sides of the bottom end of the connecting rod 10. The two stirring rollers 12 are connected to the connecting rod 10 through a first rotating component. One side of the connecting rod 10 is connected to a moving rod 7 through a second rotating component. The moving rod 7 is slidably installed inside the air-drying device body 1. A threaded rod 8 is embedded in the moving rod 7. The threaded rod 8 is rotatably installed inside the air-drying device body 1, and one end of the threaded rod 8 is fixedly connected to a motor 9.

[0037] There are multiple air outlets 6 evenly distributed to increase the contact area between hot air and PA66;

[0038] Through the setting of the mobile component, when the PA66 needs to be air-dried, the PA66 is first placed in the containing frame 3, and the air dryer is started and the hot air is finally discharged from the air outlet 6 through the first air duct 4 and the second air duct 5 to dry the PA66 in the containing frame 3;

[0039] At the same time, the motor 9 can be started to drive the threaded rod 8 to rotate, the rotation of the threaded rod 8 drives the moving rod 7 to move back and forth, the movement of the moving rod 7 drives the movement of the connecting rod 10, and the movement of the connecting rod 10 drives the movement of the stirring roller 12, so that the stirring roller 12 pushes the PA66 in the accommodating frame 3 to prevent the accumulation of PA66 during the air-drying process, thereby avoiding the current air-drying device mainly relying on the air dryer, and achieving drying by blowing hot air to the PA66 material. Due to the small hot air outlet range of the device, the contact area between PA66 and the hot air is limited, resulting in low air-drying efficiency, thereby improving the air-drying efficiency of the device.

[0040] like Figures 1 to 12 As shown, the first rotating assembly includes a connecting shaft 11 fixedly mounted on one side of the connecting rod 10, a second rotating shaft 22 is embedded inside the connecting shaft 11, a first gear 20 is fixedly mounted on one end of the second rotating shaft 22, the bottom end of the first gear 20 is meshedly connected with the first rack plate 21, the first rack plate 21 is fixedly mounted inside the main body 1 of the air-drying device, an end of the second rotating shaft 22 away from the first gear 20 is fixedly connected with the first bevel gear 24, the bottom end of the first bevel gear 24 is meshedly connected with the second bevel gear 25, a third rotating shaft 26 is fixedly mounted on the bottom end of the second bevel gear 25, a third bevel gear 27 is fixedly mounted on the bottom end of the third rotating shaft 26, a fourth bevel gear 28 is meshedly connected on the bottom end of the third bevel gear 27, and there are two symmetrical fourth bevel gears 28, one end of the two fourth bevel gears 28 are fixedly connected to the first rotating shaft 14, the first rotating shaft 14 is fixedly mounted on one end of the stirring roller 12, a stirring rod 13 is fixedly mounted on the outer wall of the stirring roller 12, and the stirring rod 13 is evenly arranged in a ring array.

[0041] By setting the first rotating assembly, when the connecting rod 10 moves in the air-drying device body 1, the movement of the connecting rod 10 drives the movement of the connecting shaft 11, and the movement of the connecting shaft 11 drives the movement of the first gear 20. The first gear 20 meshes with the first rack plate 21 and rotates. The rotation of the first gear 20 drives the rotation of the second rotating shaft 22. The rotation of the second rotating shaft 22 drives the rotation of the first bevel gear 24. The rotation of the first bevel gear 24 drives the rotation of the second bevel gear 25. The rotation of the second bevel gear 25 drives The third rotating shaft 26 rotates, and the rotation of the third rotating shaft 26 drives the rotation of the third bevel gear 27. The rotation of the third bevel gear 27 drives the rotation of the first rotating shaft 14. The rotation of the first rotating shaft 14 drives the rotation of the stirring roller 12. The rotation of the stirring roller 12 drives the rotation of the stirring rod 13, thereby stirring the PA66 in the accommodating frame 3, so that the PA66 particles or materials are constantly turned over in the accommodating frame 3, increasing the contact area with the flowing air, thereby accelerating the evaporation rate of water and further improving the air-drying efficiency of the device.

[0042] like Figures 1 to 12 As shown, the second rotating shaft 22 is rotatably mounted inside the connecting shaft 11 , and a coil spring 23 is mounted on the outer wall of the second rotating shaft 22 .

[0043] A plurality of groups of teeth blocks are arranged on the top of the first rack plate 21 and are evenly distributed;

[0044] When the first gear 20 is engaged with the tooth block at the top of the first rack plate 21, it rotates. The rotation of the first gear 20 drives the rotation of the second rotating shaft 22. When the second rotating shaft 22 rotates, the coil spring 23 deforms to store elastic potential energy. When the first gear 20 is disengaged from the tooth block at the top of the first rack plate 21, the elastic potential energy is released by the coil spring 23 to reverse the second rotating shaft 22, thereby causing the stirring roller 12 to rotate back and forth, ensuring that each part can be evenly dried to avoid local over-drying or over-wetting.

[0045] like Figures 1 to 12 As shown, a connecting pipe 19 is fixedly connected to one side of the second air duct 5 , and one end of the connecting pipe 19 away from the first air duct 4 is embedded in the second rotating shaft 22 and extends to the inside of the third rotating shaft 26 and the first rotating shaft 14 , and a through hole 15 is opened inside the stirring roller 12 .

[0046] The connecting pipe 19 passes through the second rotating shaft 22, the third rotating shaft 26 and the fourth bevel gear 28, and is embedded in the first rotating shaft 14. The connecting pipe 19 is rotatably connected to the first rotating shaft 14.

[0047] The bottom end of the connecting pipe 19 is set to an inverted T shape, and the end is connected to the inner cavity of the stirring roller 12;

[0048] During air drying, a portion of the hot air in the second air duct 5 is transported to the interior of the stirring roller 12 through the connecting pipe 19 and discharged through the through hole 15, so that the stirring roller 12 emits hot air while rotating, increasing the contact area between PA66 and the hot air, thereby accelerating the evaporation rate of water and improving the air drying efficiency of the device.

[0049] like Figures 1 to 12 As shown, a sphere 16 is disposed inside the stirring roller 12 , and a plurality of spheres 16 are disposed.

[0050] The ball 16 is made of a water-absorbent material, such as a cotton ball or a wool ball. Since some water will be released during the air-drying process of PA66, the ball 16 can absorb some of the water to improve the air-drying effect.

[0051] When the stirring roller 12 rotates, the ball 16 shakes inside the stirring roller 12 , and the ball 16 collides with the stirring roller 12 , which can prevent a part of the PA66 from being stuck in the through hole 15 .

[0052] like Figures 1 to 12 As shown, fixing rods 17 are evenly installed inside the stirring roller 12 , and the fixing rods 17 are fixedly connected to the stirring roller 12 .

[0053] The rotation of the stirring roller 12 drives the rotation of the fixing rod 17. During the rotation, the fixing rod 17 contacts the ball 16 and moves the ball 16, which helps the ball 16 to shake and collide inside the stirring roller 12. This can not only prevent PA66 particles from being stuck in the through hole 15, but also make the PA66 outside the stirring roller 12 shake, thereby improving the hot air circulation effect.

[0054] like Figures 1 to 12 As shown, one end of the stirring rod 13 is fixedly connected to an elastic member 18 , and the elastic member 18 is fixedly mounted on the outer wall of the stirring roller 12 .

[0055] The stirring rod 13 has a certain elasticity through the elastic member 18. When the stirring roller 12 drives the stirring rod 13 to rotate and contact the PA66, it helps the PA66 to move and prevent local overheating.

[0056] like Figures 1 to 12 As shown, the second rotating assembly includes a fourth rotating shaft 36 embedded in the moving rod 7, one end of the fourth rotating shaft 36 is fixedly connected to the connecting rod 10, and the other end of the fourth rotating shaft 36 is connected to the second gear 33 through a transmission assembly. The second gear 33 is arranged at the top of the moving rod 7, and one side of the second gear 33 is meshedly connected to the second rack plate 32, and the bottom end of the second rack plate 32 is fixedly connected to the connecting plate 30, and one end of the connecting plate 30 is fixedly connected to the protrusion 29.

[0057] Through the setting of the second rotating component, when PA66 needs to be air-dried, the containing frame 3 is slid into the air-drying device body 1, so that the containing frame 3 is pushed into the air-drying device body 1, and when the side wall of the containing frame 3 contacts the protrusion 29, the protrusion 29 is pushed to slide into the air-drying device body 1, and the movement of the protrusion 29 drives the movement of the connecting plate 30, and the movement of the connecting plate 30 drives the movement of the second rack plate 32, and the movement of the second rack plate 32 drives the rotation of the second gear 33. The rotation of the second gear 33 drives the fourth rotating shaft 36 to rotate through the transmission component, and the rotation of the fourth rotating shaft 36 drives the rotation of the connecting rod 10, and the connecting rod 10 drives the stirring roller 12 to rotate downward into the containing frame 3.

[0058] like Figures 1 to 12 As shown, the transmission assembly includes a worm wheel 35 fixedly mounted on one end of the fourth rotating shaft 36 , one side of the worm wheel 35 is meshingly connected with a worm 34 , and the worm 34 is fixedly mounted on the bottom end of the second gear 33 .

[0059] Through the setting of the transmission component, when the second gear 33 rotates, it drives the worm 34 to rotate, and the rotation of the worm 34 drives the worm wheel 35 to rotate, and the rotation of the worm wheel 35 drives the fourth rotating shaft 36 to rotate, so that it has self-locking. When the accommodating frame 3 is not placed in the air-drying device body 1 for drying, the connecting rod 10, the connecting shaft 11 and the internal chamber of the air-drying device body 1 are kept horizontal to prevent them from rotating downward due to their own gravity, thereby improving the stability of the device.

[0060] like Figures 1 to 12 As shown, the connecting plate 30 is slidably installed inside the air-drying device body 1, and a spring 31 is provided on one side of the connecting plate 30.

[0061] When the protrusion 29 slides into the main body 1 of the air-drying device, the spring 31 is deformed by force to store elastic potential energy. When the accommodating frame 3 is taken out after drying is completed, the accommodating frame 3 is separated from the protrusion 29, and the elastic potential energy released by the spring 31 pushes the connecting plate 30 to move outward and reset, thereby causing the connecting rod 10 and the stirring roller 12 to rotate upward, making it easier for the accommodating frame 3 to be taken out of the main body 1 of the air-drying device.

[0062] Working principle and usage process:

[0063] When the PA66 needs to be air-dried, the PA66 is first placed in the receiving frame 3, and then the receiving frame 3 is placed in the air-drying device body 1 and the receiving frame 3 is pushed into the air-drying device body 1;

[0064] When the accommodating frame 3 contacts the protrusion 29, the protrusion 29 is pushed to slide into the main body 1 of the air-drying device. The movement of the protrusion 29 drives the movement of the connecting plate 30. The movement of the connecting plate 30 causes the spring 31 to deform under force to store elastic potential energy.

[0065] At the same time, the movement of the connecting plate 30 drives the movement of the second rack plate 32, the movement of the second rack plate 32 drives the rotation of the second gear 33, the rotation of the second gear 33 drives the rotation of the worm 34, the rotation of the worm 34 drives the rotation of the worm wheel 35, the rotation of the worm wheel 35 drives the rotation of the fourth rotating shaft 36, the rotation of the fourth rotating shaft 36 drives the rotation of the connecting rod 10, the rotation of the connecting rod 10 drives the rotation of the stirring roller 12, so that the stirring roller 12 rotates downward into the accommodating frame 3;

[0066] Then the protective door 2 is closed, and the air dryer is started. The hot air is transmitted through the first air duct 4 and the second air duct 5 and finally discharged from the air outlet 6 into the air drying device body 1 to air dry the PA66;

[0067] During drying, the motor 9 can be started as needed, and the motor 9 starts to drive the threaded rod 8 to rotate, and the rotation of the threaded rod 8 drives the moving rod 7 to move back and forth, and the movement of the moving rod 7 drives the movement of the connecting rod 10, and the movement of the connecting rod 10 drives the movement of the stirring roller 12, so that the stirring roller 12 pushes the PA66 in the accommodating frame 3;

[0068] At the same time, the movement of the connecting rod 10 drives the movement of the connecting shaft 11, and the movement of the connecting shaft 11 drives the movement of the first gear 20. The first gear 20 meshes with the first rack plate 21 and rotates. The rotation of the first gear 20 drives the rotation of the second rotating shaft 22. The rotation of the second rotating shaft 22 drives the rotation of the first bevel gear 24. The rotation of the first bevel gear 24 drives the rotation of the second bevel gear 25. The rotation of the second bevel gear 25 drives the rotation of the third rotating shaft 26. The rotation of the third rotating shaft 26 drives the rotation of the third bevel gear 27. The rotation of the third bevel gear 27 drives the rotation of the first rotating shaft 14. The rotation of the first rotating shaft 14 drives the rotation of the stirring roller 12. The rotation of the stirring roller 12 drives the rotation of the stirring rod 13 to stir the PA66 in the accommodating frame 3.

[0069] When the PA66 air-drying process is completed, the containing frame 3 is taken out from the air-drying device body 1, the containing frame 3 is separated from the protrusion 29, and the elastic potential energy released by the spring 31 pushes the connecting plate 30 to move outward and reset, so that the connecting rod 10 and the stirring roller 12 rotate upward and separate from the containing frame 3, and the containing frame 3 is taken out to complete the air-drying process of PA66.
