Technical Field

[0001] This utility model belongs to the field of down dehumidification technology, and in particular relates to a down jacket feather moisture-proof and dehumidification device. Background Technology

[0002] During processing, down undergoes dehumidification and sterilization to ensure its safety and prevent microbial growth, maintaining a good level of dryness. This process is typically performed by airflow wiping.

[0003] Chinese patent CN220959453U discloses a down dehumidification and sterilization device, including a base box, a support plate, and a material cylinder. The device is characterized by a blowing structure on the base box, a column on the top of the base box, a top plate on the top of the column, a driving structure on the top plate, a movably connected support plate to the column, a movably connected support plate to the driving structure, and an agitation structure on the support plate. The material cylinder is movably mounted on the support plate and has through holes on its side walls and bottom.

[0004] However, the aforementioned patents have the following problems:

[0005] The aforementioned patent uses a stirring rod to stir the down in the stirring cylinder and airflow to dry the down in the stirring cylinder. However, when air is introduced into the stirring cylinder, the down tends to accumulate at the air outlet of the device, which can easily cause the air outlet to be blocked. At the same time, the down that is blocked at the air outlet clumps together and is not easy to dry. Utility Model Content

[0006] This utility model provides a down jacket feather moisture-proof and dehumidifying device, which aims to solve the problem that when air is introduced into the mixing drum of the above-mentioned patent, the down tends to accumulate on the air outlet of the device, which can easily lead to blockage of the air outlet. At the same time, the down that is blocked at the air outlet clumps together and is not easy to dry.

[0007] This utility model is implemented as follows: a down jacket feather moisture-proof and dehumidifying device includes a drying chamber, an inlet pipe connected to the top of the drying chamber, an outlet pipe provided at the bottom of the drying chamber, a first air outlet slot connected to the front of the drying chamber, a second air outlet slot connected to the rear of the drying chamber, a rotating chamber provided inside the drying chamber, the outer periphery of the rotating chamber fitting against the inner periphery of the drying chamber, multiple conveying chambers opened on the outer periphery of the rotating chamber, and a ventilation net provided between each of the multiple conveying chambers and the rotating chamber;

[0008] Both sides of the drying chamber are equipped with barrier screens, and the outer periphery of both barrier screens is fixedly connected to the inner wall of the drying chamber, and both barrier screens are in close contact with the drying chamber.

[0009] A drive mechanism is provided between the rotating chamber and the drying chamber, and the drive mechanism is used to drive the rotating chamber to rotate.

[0010] The drying chamber is provided with an opening and closing mechanism on one side, which is used to control the sealing and closing between the first air outlet slot and the second air outlet slot.

[0011] Preferably, the driving mechanism includes a rotary joint and a stepper motor. The rotary joint is fixedly connected to the drying chamber. One end of the rotary joint is connected to an air inlet pipe, and the other end of the rotary joint is rotatably connected to a connecting cylinder. The connecting cylinder passes through the rotating chamber in the middle. The connecting cylinder is fixedly connected to the rotating chamber. Multiple through holes are provided between the connecting cylinder and the rotating chamber. All of the multiple through holes are opened on the outer periphery of the connecting cylinder. The end of the connecting cylinder away from the rotary joint is rotatably connected to the inner wall of the drying chamber. A toothed ring is fixedly connected to the outer periphery of the connecting cylinder.

[0012] The side wall of the stepper motor is fixedly connected to the drying chamber, and a gear is fixedly connected to the output end of the stepper motor, which meshes with a gear ring.

[0013] By starting the stepper motor, the gear can be driven to rotate, and the gear will drive the gear ring and connecting cylinder to rotate. At the same time, the connecting cylinder can drive the rotating chamber and multiple conveying chambers around the rotating chamber to rotate inside the drying chamber.

[0014] Preferably, the opening and closing mechanism includes an electric push rod, the side wall of which is fixedly connected to the drying chamber, and a connecting frame is fixedly connected to the output end of the electric push rod. The connecting frame is U-shaped, and sealing plates are fixedly connected to both ends of the connecting frame. One of the sealing plates matches the first air outlet groove, and the other sealing plate matches the second air outlet groove.

[0015] By activating the electric push rod to extend, the connecting frame can be moved forward. At this time, the connecting frame will cause one of the sealing plates to seal the second air outlet slot, and the connecting frame will also cause the other sealing plate to separate from the first air outlet slot.

[0016] By activating the electric push rod to retract, the connecting frame can be moved to the rear. At this time, the connecting frame will cause one of the sealing plates to seal the first air outlet slot, and at the same time, the connecting frame will cause the other sealing plate to separate from the second air outlet slot.

[0017] Preferably, the ventilation mesh is shaped like a "U".

[0018] By setting the ventilation mesh in a "U" shape, the ventilation area of ​​the mesh can be increased.

[0019] Preferably, both of the sealing plates are provided with sealing gaskets, and both sealing gaskets are made of rubber material;

[0020] By setting sealing gaskets on the surfaces of the two sealing plates, the airtightness between the two sealing plates and the first and second air outlet slots can be improved respectively.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Multiple conveying chambers allow down to be placed in batches, preventing excessive down accumulation that would prevent hot air from evenly penetrating the large quantity of down. The opening and closing mechanism prevents down from being pressed against the two blocking screens by air pressure due to the unchanged outflow duct of hot air in the conveying chamber, thus ensuring even drying. Furthermore, the reciprocating change of the outflow duct of hot air in the conveying chamber causes the down to vibrate repeatedly, making it more loose and thus improving the drying efficiency.

[0042] On one side of the drying bin 1, an opening and closing mechanism 3 is provided. The opening and closing mechanism 3 is used to control the sealing and closing between the first air outlet groove 13 and the second air outlet groove 14.

[0043] Further, the driving mechanism 2 includes a rotary joint 21 and a stepping motor 22. The rotary joint 21 is fixedly connected to the drying bin 1. An air inlet pipe 23 is communicated and arranged at one end of the rotary joint 21. A connecting cylinder 24 is rotatably communicated and arranged at the other end of the rotary joint 21. The middle of the connecting cylinder 24 penetrates through the rotating bin 15. The connecting cylinder 24 is fixedly connected to the rotating bin 15. A plurality of through holes 25 are communicated and arranged between the connecting cylinder 24 and the rotating bin 15.

The end of the connecting cylinder 24 far from the rotary joint 21 is rotatably connected to the inner wall of the drying bin 1. A toothed ring 26 is fixedly connected to the outer periphery of the connecting cylinder 24;

[0044] The side wall of the stepping motor 22 is fixedly connected to the drying bin 1. A gear 27 is fixedly connected to the output end of the stepping motor 22. The gear 27 is meshed and connected to the toothed ring 26.

[0045] Further, the opening and closing mechanism 3 includes an electric push rod 31. The side wall of the electric push rod 31 is fixedly connected to the drying bin 1. A connecting frame 32 is fixedly connected to the output end of the electric push rod 31. The connecting frame 32 is in a "U" shape. Sealing plates 33 are fixedly connected to both ends of the connecting frame 32.

[0046] Further, the ventilation net 17 is in a "U" shape.

[0047] Further, sealing gaskets 4 are provided on the surfaces of the two sealing plates 33. The two sealing gaskets 4 are both made of rubber materials.

[0048] The working principle and usage process of the present utility model: After the present utility model is installed, by starting the stepping motor 22, the gear 27 can be driven to rotate, and at the same time, the gear 27 can drive the toothed ring 26 and the connecting cylinder 24 to rotate. At the same time, the connecting cylinder 24 can drive the rotating bin 15 and the plurality of conveying cavities 16 on the outer periphery of the rotating bin 15 to rotate in the drying bin 1;

[0049] At this time, the feeding pipe 11 is opened, and thus down feathers are sequentially conveyed into the plurality of conveying cavities 16;

[0050] Then, hot air is introduced into the air inlet pipe 23 by an external hot air blower. At the same time, the hot air will enter the drying chamber 1 through multiple through holes 25 on its surface. The hot air in the drying chamber 1 will enter multiple conveying chambers 16 through multiple ventilation nets 17. The hot air entering the conveying chambers 16 can dry the down in the conveying chambers 16. Then, the hot air will pass through the blocking screens 18 on both sides and be discharged to the outside of the device through the first air outlet 13 and the second air outlet 14 respectively.

[0051] By activating the electric push rod 31 to extend, the connecting frame 32 can be moved forward. At this time, the connecting frame 32 will cause one of the sealing plates 33 to seal the second air outlet 14, and at the same time, the connecting frame 32 will cause the other sealing plate 33 to separate from the first air outlet 13.

[0052] By activating the electric push rod 31 to retract, the connecting frame 32 can be moved to the rear. At this time, the connecting frame 32 will cause one of the sealing plates 33 to seal the first air outlet 13, and at the same time, the connecting frame 32 will cause the other sealing plate 33 to separate from the second air outlet 14.

[0053] When the first air outlet slot 13 is closed and the second air outlet slot 14 is open, the hot air in the conveying chamber 16 will pass through one of the blocking screens 18 and be discharged through the second air outlet slot 14. When the second air outlet slot 14 is closed and the first air outlet slot 13 is open, the hot air in the conveying chamber 16 will pass through the other blocking screen 18 and be discharged through the other air outlet slot. The above steps can avoid the down in the conveying chamber 16 being pressed against the surface of the two blocking screens 18 by the wind pressure and not being dried evenly because the outflow channel of the hot air in the conveying chamber 16 remains unchanged. Moreover, the outflow channel of the hot air in the conveying chamber 16 changes back and forth in opposite directions, which can make the down in the conveying chamber 16 vibrate back and forth, thereby making the down more loose, which is conducive to improving the drying efficiency of the down.

[0054] After the down is dried in the multiple conveying chambers 16, the discharge pipe 12 can be opened to discharge the down.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
