Description

Technical Field

[0001] This utility model belongs to the field of aerospace sealing component processing technology, specifically relating to a drying device for aerospace sealing component processing. Background Technology

[0002] A drying device for aerospace sealing components is a piece of equipment designed for the processing of sealing components in the aerospace field. Its core function is to generate hot air through heating elements and circulate it to the drying chamber via a fan, causing moisture to evaporate from the surface of the sealing components. This device must meet the high precision and high reliability requirements of the aerospace industry for sealing components. It typically features precise temperature control, uniform airflow distribution, and automated operation. It not only removes moisture and solvents, ensuring that the sealing components are not affected by residual moisture during subsequent processing or assembly, thus preventing corrosion or performance degradation, but also improves production efficiency, reduces manual intervention, shortens the production cycle, and enhances overall efficiency.

[0003] Chinese Patent Publication No. CN221238079U relates to the field of sealing component processing technology. This utility model discloses a drying device for sealing component processing, comprising: a drying chamber, a rotating shaft rotatably positioned at the center of the drying chamber, a servo motor fixedly installed at the bottom of the drying chamber, and the output end of the servo motor fixedly connected to the bottom of the rotating shaft; and trays symmetrically fixedly installed on the surface of the rotating shaft. This utility model incorporates components such as a servo motor, a placement box, and an arc-shaped extrusion block. As the servo motor drives the symmetrically mounted trays on the rotating shaft to rotate, one side of the symmetrically mounted placement box intermittently presses against the surface of the arc-shaped extrusion block, causing the placement box to reciprocate. This, in turn, causes the sealing components inside the placement box to shake, preventing the sealing components from fitting too tightly and creating gaps between adjacent sealing components, thereby improving the drying efficiency of the rubber sealing components.

[0004] In practical use, this utility model typically relies on warm air to dry aerospace seals. However, the warm air in existing drying devices for aerospace seal processing often enters the drying device from a fixed position, making it difficult to achieve sufficient and uniform contact with the aerospace seals. This uneven contact state can easily lead to inconsistent drying effects, resulting in low drying efficiency and thus making the drying device for aerospace seal processing less practical.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1:

[0030] Please see Figure 1-6 This utility model provides a drying device for processing aerospace sealing components, comprising:

[0031] Drying oven 1 and warm air blower 2;

[0032] The positioning shaft 3 is set inside the drying box 1. The warm air blower 2 is located at the top of the drying box 1. The drying box 1 is equipped with a "U"-shaped ventilation plate 4, which is located at the top of the positioning shaft 3. Multiple nozzles 5 are provided on both sides of the inner wall.

[0033] Multiple bearing plates 6 are all located on the outside of the positioning shaft 3. Multiple positioning plates 7 are provided on the outside of the positioning shaft 3. Multiple bearing plates 6 are all provided with positioning grooves that are adapted to the positioning shaft 3 and the positioning plates 7. Multiple positioning plates 7 are respectively located in multiple positioning grooves.

[0034] The drive shaft 8 is rotatably connected to one side of the bottom of the drying oven 1. The air outlet 10 of the heater 2 is connected to the ventilation plate 4. The upper end of the positioning shaft 3 is provided with a ventilation groove. The upper end of the ventilation plate 4 is provided with a guide pipe 9 that is adapted to the ventilation groove. The guide pipe 9 is located in the ventilation groove and is slidably connected to the side wall of the ventilation groove.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sidewall of the ventilation slot is provided with multiple air outlets 10, all of which are inclined and located on the upper end of multiple support plates 6.

[0036] Through its design, the multiple inclined air outlets 10 located on the upper part of the multiple bearing plates 6 can evenly blow warm air into the drying chamber 1 when the positioning shaft 3 rotates, so that it can evenly and fully contact the aerospace seals, ensuring the effect and efficiency of drying the aerospace seals.

[0037] Specifically, such as Figure 2 and Figure 3 As shown, a drive motor 11 is provided at the bottom of the drying chamber 1. The drive motor 11 is existing technology and will not be described in detail here. The output end of the drive motor 11 extends into the drying chamber 1 and is located at the bottom of the positioning shaft 3. A transmission shaft 8 is rotatably connected to one side of the bottom of the drying chamber 1. Both the transmission shaft 8 and the output end of the drive motor 11 are provided with pulleys. The two pulleys are provided with the same transmission belt 12. When the drive motor 11 is started, its output end can not only drive the positioning shaft 3 and multiple bearing plates 6 to rotate, but also drive the transmission shaft 8 to rotate, so that the warm air can come into more full contact with the aerospace sealing parts, ensuring the drying effect of the aerospace sealing parts.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the ventilation plate 4 is provided with an internal gear ring 13, and the upper end of the transmission shaft 8 is provided with a transmission wheel 14 that meshes with the internal gear ring 13. The internal gear ring 13 is larger than the transmission wheel 14. The transmission shaft 8 can drive the ventilation plate 4 and multiple nozzles 5 to rotate through the transmission wheel 14 and the internal gear ring 13. Moreover, its rotation direction is opposite to that of the positioning shaft 3 and multiple bearing plates 6, which improves the fullness of contact between the warm air and the aerospace sealing components.

[0039] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, both sides of the bottom end of the ventilation plate 4 are provided with abutment rods 15, and the bottom ends of the two abutment rods 15 are both arc-shaped. The bottom end of the inner wall of the drying box 1 is provided with multiple abutment plates 16, and the multiple abutment plates 16 are all arc-shaped. The abutment rods 15 on both sides of the bottom end of the ventilation plate 4, together with the multiple abutment plates 16, enable the ventilation plate 4 to move up and down when rotating, thereby expanding the range of warm air that can be sprayed by the multiple nozzles 5 and improving the uniformity of the contact between the warm air and the aerospace sealing components.

[0040] Specifically, such as Figure 2 , Figure 3 and Figure 6As shown, the upper end of the inner wall of the drying oven 1 has a "T"-shaped snap-fit ​​groove with a matching snap-fit ​​ring 17. The snap-fit ​​groove and the snap-fit ​​ring 17 can limit the position of the ventilation plate 4 without affecting its rotation, thus preventing it from shifting during use. Guide rods 18 are provided on both sides of the upper end of the ventilation plate 4. Guide grooves matching the guide rods 18 are provided on both sides of the bottom end of the snap-fit ​​ring 17. The upper ends of the two guide rods 18 are located in the two guide grooves respectively, and each is provided with a limiting spring 19. The other ends of the two limiting springs 19 are respectively set on the upper end of the two guide grooves. The two guide rods 18 can limit the vertical movement of the ventilation plate 4 and the multiple nozzles 5, preventing them from shifting. When the abutment rod 15 is separated from the abutment plate 16, it can drive the ventilation plate 4 and the multiple nozzles 5 to return to their original positions, thus enabling the ventilation plate 4 and the multiple nozzles 5 to move up and down.

[0041] Example 2:

[0042] Please see Figure 1-6 This utility model provides a drying device for processing aerospace sealing components, comprising:

[0043] Drying oven 1 and warm air blower 2;

[0044] The positioning shaft 3 is set inside the drying box 1. The warm air blower 2 is located at the top of the drying box 1. The drying box 1 is equipped with a "U"-shaped ventilation plate 4, which is located at the top of the positioning shaft 3. Multiple nozzles 5 are provided on both sides of the inner wall.

[0045] Multiple bearing plates 6 are all located on the outside of the positioning shaft 3. Multiple positioning plates 7 are provided on the outside of the positioning shaft 3. Multiple bearing plates 6 are all provided with positioning grooves that are adapted to the positioning shaft 3 and the positioning plates 7. Multiple positioning plates 7 are respectively located in multiple positioning grooves.

[0046] The drive shaft 8 is rotatably connected to one side of the bottom of the drying oven 1. The air outlet 10 of the heater 2 is connected to the ventilation plate 4. The upper end of the positioning shaft 3 is provided with a ventilation groove. The upper end of the ventilation plate 4 is provided with a guide pipe 9 that is adapted to the ventilation groove. The guide pipe 9 is located in the ventilation groove and is slidably connected to the side wall of the ventilation groove.

[0047] Specifically, such as Figure 5 As shown, each of the multiple bearing plates 6 has a handle 20 on one side, and each of the multiple positioning grooves has a limiting plate 21 on both sides. Each of the multiple positioning plates 7 has a limiting groove on both sides that is adapted to the limiting plate 21. The multiple limiting plates 21 are located in the multiple limiting grooves and are slidably connected to the side wall of the limiting groove.

[0048] Through its design, the limiting plates 21 set in multiple bearing plates 6, together with the limiting grooves on multiple positioning plates 7, enable multiple bearing plates 6 to move horizontally, thereby facilitating the picking up or placing of aerospace seals and making the drying device for aerospace seal processing more convenient to use.

[0049] Specifically, such as Figure 5 As shown, each of the multiple limiting plates 21 is provided with a compression spring 22 on one side, and the other end of the multiple compression springs 22 is respectively provided on one side of the multiple limiting grooves. The multiple compression springs 22 can limit the position of the multiple limiting plates 21, thereby limiting the position of the carrier plate 6 and enabling the carrier plate 6 to move into the drying oven 1.

[0050] See Figure 1-6 When using the drying device to dry aerospace seals, firstly, the carrier plate 6 needs to be moved to the outside of the drying chamber 1 by pulling the handle 20. The aerospace seals to be dried are then placed in multiple carrier plates 6. Next, the heater 2 is started, which directs warm air into the ventilation plate 4 and the positioning shaft 3. The warm air entering the ventilation plate 4 is sprayed out through multiple nozzles 5. When the warm air enters the ventilation slots in the positioning shaft 3, it is discharged through multiple air outlets 10, ensuring even contact between the warm air and the aerospace seals. Then, the drive motor 11 is started, and its output drives the positioning shaft 3 and multiple carrier plates 6 to rotate, further distributing the warm air. The air enters the drying chamber 1 evenly, allowing the aerospace seals on the multiple bearing plates 6 to come into more uniform contact with the warm air. The output of the drive motor 11 can also drive the drive shaft 8 to rotate via the transmission belt 12. In conjunction with the transmission wheel 14 and the internal gear ring 13, the ventilation plate 4 and multiple nozzles 5 can rotate, further improving the uniformity of the warm air in the drying chamber 1. When the ventilation plate 4 rotates, the abutment rods 15 on both sides of the bottom will intermittently contact multiple abutment plates 16. In conjunction with the two guide rods 18 and two limit springs 19, the ventilation plate 4 and multiple nozzles 5 can move up and down, making the drying chamber 1 more thorough and efficient in drying the aerospace seals.
