Description

Technical Field

[0001] The invention relates to the technical field of paint surface drying, in particular to a device for drying the surface of a rail transit deflector cover. Background Art

[0002] When the train is running, the fairing will be exposed to humid air, rain, dust, industrial pollutants and other environments. Metal materials are prone to oxidation corrosion, and non-metallic materials may also age due to long-term contact with water vapor. The coating formed by paint acts as a "protective shield", isolating air and moisture from direct contact with the fairing body, avoiding electrochemical corrosion or chemical corrosion, and extending its structural strength and service life.

[0003] After the train air deflector is painted, it needs to be dried to accelerate the solidification and setting of the paint surface. The air deflector needs to be moved to a drying room for drying. Since the air outlet of the drying room is fixed, the air deflector usually has a complex curved surface. The wind in a single direction is difficult to evenly cover all surfaces. In addition, the hot air in a single direction will cause temperature differences on the surface of the air deflector, affecting the drying effect of the paint surface.

[0004] Based on this, a rail transit deflector surface drying device is now provided, which can eliminate the disadvantages of the existing device. Summary of the Invention

DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, Figures 1-12 As shown, a rail transit deflector surface drying device includes a drying room 1 and a rotating component 5. The side wall of the drying room 1 is provided with a dehumidification fan 3 and a louver air inlet 4, the top wall of the drying room 1 is provided with several circulating heating dryers 2, and the bottom wall of the drying room 1 is provided with a rotating component 5 for driving the deflector to rotate, so that each side of the deflector can be dried evenly.

[0034] The deflector is moved to the rotating assembly 5, and the circulating heating dryer 2 is started. The circulating heating dryer 2 drives the air in the drying room 1 to circulate and heat the air, thereby drying the paint surface of the deflector;

[0035] When the air humidity in the drying room 1 becomes high, the dehumidification fan 3 can be started to discharge the air with high humidity in the drying room 1 out of the drying room 1, and the air with low humidity outside enters the drying room 1 through the louver air inlet 4.

[0036] In one embodiment, the rotating assembly 5 includes a mesh turntable 6, a threaded rod 7, a rotating shaft 8, and a motor 9. The bottom wall of the drying room 1 is provided with a rotating shaft 8 that rotates through a bearing seat. The bottom wall of the drying room 1 is provided with a motor 9. The motor 9 drives the rotating shaft 8 to rotate through a gear transmission member. The mesh turntable 6 is provided at the top of the rotating shaft 8.

[0037] When the air deflector is placed on the rotating component 5, the motor 9 is started, the motor 9 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the mesh turntable 6 to rotate, and the mesh turntable 6 drives the air deflector to rotate, so that each side of the air deflector can circulate in turn close to the air outlet of the circulating heating dryer 2, so that the paint surface of the air deflector is dried more evenly, and because the mesh turntable 6 has multiple mesh holes, the hot air can fully dry the air deflector from the bottom of the air deflector upwards, perform all-round drying, and further improve the drying effect.

[0038] In one embodiment, a threaded rod 7 is provided on the lower surface of the mesh turntable 6, and the threaded rod 7 is threadedly connected to the rotating shaft 8. The rotation direction of the mesh turntable 6 is the same as the tightening direction of the threaded rod 7. A guide plate 10 and a material receiving box 11 are fixed to the lower surface of the drying room 1 by bolts. The material receiving box 11 is annular and is arranged on the periphery of the guide plate 10. The material receiving box 11 is provided with a guide pipe 14, and the guide pipe 14 runs through the drying room 1. A scraper module 13 is provided on the inclined surface of the guide plate 10, which is used to scrape the paint remaining on the guide plate 10 into the material receiving box 11.

[0039] In one embodiment, the scraper module 13 includes a first scraper 16 . A rotating plate 15 is fixedly connected to the circumference of the rotating shaft 8 . The rotating plate 15 is fixedly connected to two symmetrical first scrapers 16 via a bracket. The first scrapers 16 abut against the inclined surface of the guide plate 10 .

[0040] When the rotating shaft 8 drives the mesh turntable 6 to rotate, the rotating shaft 8 drives the rotating plate 15 to rotate, and the rotating plate 15 drives the first scraper 16 to rotate. The first scraper 16 scrapes off the paint attached to the surface of the material receiving box 11, and then falls into the material receiving box 11 under the action of gravity for centralized collection and cleaning, reducing the cleaning difficulty and cleaning workload of the staff.

[0041] In one embodiment, the rotating plate 15 is fixedly connected to two symmetrical guide frames 17 through a bracket. The guide frame 17 is provided with a sliding block groove and a second scraper groove. The inner side wall of the sliding block groove is slidingly connected to a sliding block 24. The guide frame 17 is connected to a bidirectional screw 22 through a bearing. The bidirectional screw 22 is threadedly connected to the sliding block 24. The two bidirectional screws 22 are fixedly connected to a bevel gear 29 at one end close to each other. The lower surface of the drying room 1 is fixedly connected to a fixed frame 12, and the fixed frame 12 is fixedly connected to a bevel gear ring 30. The two bevel gears 29 are both engaged with the bevel gear ring 30. The side wall of the sliding block 24 is provided with a second scraper 23, and the second scraper 23 abuts against the inclined surface of the first scraper 16.

[0042] While the first scraper 16 is rotating and scraping, the bevel gear 29 meshes with the bevel gear ring 30 to rotate, and the rotation of the bevel gear 29 drives the bidirectional screw 22 to rotate, and the bidirectional screw 22 drives the sliding block 24 to reciprocate back and forth in the sliding block groove, and the sliding block 24 drives the second scraper 23 to reciprocate back and forth, scraping the paint on the surface of the first scraper 16 into the material receiving box 11, completing the self-cleaning of the first scraper 16, and there is no need to frequently clean the first scraper 16 manually. In addition, it is dangerous to clean the longer first scraper 16 manually, which can easily cause scratches on the skin of the staff. In comparison, cleaning the second scraper 23 is more convenient, simple and quick.

[0043] In one embodiment, a T-shaped block 25 is fixedly connected to the side wall of the sliding block 24 , a T-shaped block groove is opened on the side wall of the guide frame 17 , and the T-shaped block 25 is slidably connected to the inner side wall of the T-shaped block groove.

[0044] In one embodiment, the second scraper 23 is rotatably connected to the sliding block 24 through a pin shaft, and a coil spring 28 is provided at the connection between the second scraper 23 and the sliding block 24. The inner side wall of the second scraper groove is fixedly connected to a partition plate 18, and the partition plate 18 divides the second scraper groove into an upper area 19 and a lower area 20. The side wall of the second scraper 23 is fixedly connected to a rotating block 26, and the rotating block 26 is embedded with an iron plate 27. Both ends of the partition plate 18 are shorter than the second scraper groove of the guide frame 17. The lower surface of the second scraper groove is fixedly connected to a magnet 21, and the magnet 21 is located at one end of the guide frame 17 and away from the rotating plate 15.

[0045] When the sliding block 24 reciprocates in the sliding block groove, the sliding block 24 moves to the outermost end of the guide frame 17, there is a gap at the leftmost end of the partition plate 18, and the magnet 21 attracts the iron plate 27, causing the second scraper 23 to rotate around the pin shaft, and the rotating block 26 leaves the upper area 19, and the second scraper 23 no longer abuts against the inclined surface of the first scraper 16, and the length of the magnet 21 is greater than the length of the gap in the partition plate 18. When the sliding block 24 moves toward the inner end of the guide frame 17, the rotating block 26 is located in the lower area 20. At this time, the second scraper 23 keeps rotating and does not contact the inclined surface of the first scraper 16, so as to avoid the dirt on the inclined surface of the first scraper 16 being transported to the inner end when the second scraper 23 moves toward the inner end of the guide frame 17, and cannot enter the receiving box 11 for collection;

[0046] When the sliding block 24 moves to the innermost end, there is also a notch at the rightmost end of the partition plate 18. The rotating block 26 rotates and resets under the action of the coil spring 28 and returns to the upper area 19. The second scraper 23 also rotates again to abut against the inclined surface of the first scraper 16, scraping the dirt on the inclined surface of the first scraper 16 into the material receiving box 11.

[0047] The above embodiment discloses a rail transit deflector surface drying device, and its specific working principle and process are as follows:

[0048] S1: The deflector is moved to the rotating assembly 5, and the circulating heating dryer 2 is started. The circulating heating dryer 2 drives the air in the drying room 1 to circulate and heat the air, thereby drying the paint surface of the deflector;

[0049] When the air humidity in the drying room 1 becomes high, the dehumidification fan 3 can be started to discharge the air with high humidity in the drying room 1 out of the drying room 1, and the air with low humidity outside enters the drying room 1 through the louver air inlet 4;

[0050] S2: When the air deflector is placed on the rotating assembly 5, the motor 9 is started, the motor 9 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the mesh turntable 6 to rotate, and the mesh turntable 6 drives the air deflector to rotate, so that each side of the air deflector is circulated in turn close to the air outlet of the circulating heating dryer 2, so that the paint surface of the air deflector is dried more evenly, and because the mesh turntable 6 has multiple mesh holes, the hot air can fully dry the air deflector from the bottom of the air deflector upwards, performing all-round drying, and further improving the drying effect;

[0051] S3: When the rotating shaft 8 drives the mesh turntable 6 to rotate, the rotating shaft 8 drives the rotating plate 15 to rotate, and the rotating plate 15 drives the first scraper 16 to rotate. The first scraper 16 scrapes off the paint attached to the surface of the receiving box 11, and then falls into the receiving box 11 under the action of gravity for centralized collection and cleaning, thereby reducing the cleaning difficulty and workload of the staff;

[0052] S4: When the first scraper 16 is rotating and scraping, the bevel gear 29 meshes with the bevel gear ring 30 to rotate. The rotation of the bevel gear 29 drives the bidirectional screw 22 to rotate. The bidirectional screw 22 drives the sliding block 24 to reciprocate back and forth in the sliding block groove. The sliding block 24 drives the second scraper 23 to reciprocate back and forth, scraping the paint on the surface of the first scraper 16 into the material receiving box 11, completing the self-cleaning of the first scraper 16. There is no need to frequently clean the first scraper 16 manually. In addition, it is dangerous to clean the long first scraper 16 manually, which can easily cause scratches on the skin of the staff. In comparison, cleaning the second scraper 23 is more convenient, simple and quick.

[0053] S5: When the sliding block 24 reciprocates in the sliding block groove, the sliding block 24 moves to the outermost end of the guide frame 17, and there is a gap at the leftmost end of the partition plate 18. The magnet 21 attracts the iron plate 27, causing the second scraper 23 to rotate around the pin shaft, and the rotating block 26 leaves the upper area 19. The second scraper 23 no longer abuts against the inclined surface of the first scraper 16, and the length of the magnet 21 is greater than the length of the gap in the partition plate 18. When the sliding block 24 moves toward the inner end of the guide frame 17, the rotating block 26 is located in the lower area 20. At this time, the second scraper 23 keeps rotating and does not contact the inclined surface of the first scraper 16, so as to avoid the dirt on the inclined surface of the first scraper 16 being transported to the inner end when the second scraper 23 moves toward the inner end of the guide frame 17, and cannot enter the receiving box 11 for collection;

[0054] When the sliding block 24 moves to the innermost end, there is also a notch at the rightmost end of the partition plate 18. The rotating block 26 rotates and resets under the action of the coil spring 28 and returns to the upper area 19. The second scraper 23 also rotates again to abut against the inclined surface of the first scraper 16, scraping the dirt on the inclined surface of the first scraper 16 into the material receiving box 11.

[0055] The mesh turntable 6 can be disassembled by manual rotation. After the drying is completed, the mesh turntable 6 can be directly disassembled for cleaning.

[0056] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
