Description

Technical Field

[0001] This utility model relates to the field of curing device technology, and in particular to a centrifugal sealing ring self-lubricating coating curing device. Background Technology

[0002] Centrifugal seals are dynamic sealing elements widely used in rotating machinery. They utilize centrifugal force to prevent leakage of the working medium and isolate external impurities. They must simultaneously possess good elasticity to ensure a tight seal and excellent wear resistance to withstand long-term friction. Since the inner wall of the seal, which directly contacts the rotating shaft, is the core area determining sealing performance and lifespan, the industry commonly employs a self-lubricating coating to reduce frictional loss in this area. After spraying, a rigorous curing process is required to achieve a strong bond with the substrate, forming a dense and mechanically stable functional layer. During curing, precise control of the heating rate, curing temperature, holding time, and cooling rate is necessary to prevent coating cracking and peeling, and to ensure that hardness and adhesion meet standards.

[0003] Currently, the curing of self-lubricating coatings for centrifugal sealing rings mostly relies on general-purpose drying equipment. In existing drying equipment, the hot air is mostly direct and the tray is solid, which leads to uneven heating of the coating and causes differences in curing quality. Poor sealing of the inlet / outlet causes a large amount of heat to leak out, resulting in serious energy waste. In addition, dust can easily enter and adhere to the surface of the uncured coating in the curing chamber, forming impurities and defects.

[0004] Therefore, this application proposes a centrifugal sealing ring self-lubricating coating curing device to solve the above problems. Utility Model Content

[0013] Compared with related technologies, the centrifugal sealing ring self-lubricating coating curing device provided by this utility model has the following beneficial effects: 1. This utility model provides a centrifugal sealing ring self-lubricating coating curing device. The device uses the cooperative design of the protective frame and the air inlet frame inside the curing chamber to direct hot air into the curing chamber through the air outlet of the air inlet frame. The hot air enters the protective frame through the connecting holes on the upper, lower and right side walls of the protective frame, thereby avoiding direct exposure of the coating to the hot air. At the same time, the ventilation holes at the bottom of the support plate placement slot ensure that the coating on the inner surface of the sealing ring can be fully contacted with the heat flow, solving the problem of uneven heating caused by traditional solid support plates, effectively reducing the risk of coating cracking and peeling, and ensuring that the coating hardness and adhesion meet the standards.

[0014] 2. This utility model provides a centrifugal sealing ring self-lubricating coating curing device. When the support plate is not inserted into the protective frame, the sealing plate of the sealing mechanism in the device seals the placement hole with the curing box under the action of the traction spring, thereby preventing heat loss in the curing box when removing the product after curing and when placing the product; at the same time, it effectively blocks external dust from entering the curing box, thereby preventing dust from adhering to the surface of the uncured coating and forming impurities and defects, and improving the cleanliness and smoothness of the coating surface.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 8 This utility model provides a technical solution: a centrifugal sealing ring self-lubricating coating curing device, including an operating table 1, an auxiliary plate 6 and a curing box 2 fixedly connected to the upper end of the operating table 1, an electric push rod 7 fixedly connected to the left end of the auxiliary plate 6, the output end of the electric push rod 7 passing through the auxiliary plate 6 and fixedly connected to a moving plate 10, a plurality of support plates 11 fixedly connected to the right end of the moving plate 10, a placement hole 15 opened on the left end of the curing box 2, a sealing mechanism provided on the left end of the placement hole 15, a protective frame 16 fixedly connected to the left inner wall of the curing box 2, an opening on the left end of the protective frame 16, the placement hole 15 located inside the left opening end of the protective frame 16, air inlet frames 19 fixedly connected to both the front and rear side walls of the protective frame 16, a temperature regulating mechanism provided on the outside of the curing box 2, and a U-shaped connecting pipe 21 provided on the right side of the curing box 2, the front and rear ends of the connecting pipe 21 passing through the right side wall of the curing box 2 and respectively connected to two air inlet frames 19; The left end of the air inlet frame 19 has several air outlets 20, and the upper and lower side walls and the right side wall of the protective frame 16 have several connecting holes 17. A temperature monitoring sensor 18 is fixedly connected to the inner right wall of the curing box 2. The air inlet frame 19 is located in the middle of the two sets of connecting holes 17. The air outlet of the air inlet frame 19 does not blow directly towards the support plate 11. The hot air enters the protective frame 16 through the connecting holes 17, thereby effectively preventing the hot air from directly hitting the coating. The vent hole 13 at the bottom of the groove 12 of the support plate 11 ensures that the coating on the inner surface of the sealing ring 14 can fully contact the heat flow. The sealing mechanism includes an L-shaped hinge frame 29 fixed to the rear end of the curing chamber 2. A hinge plate 30 is hinged to the inner side of the hinge frame 29. A sealing plate 31 is fixedly connected to the front end of the hinge plate 30. The sealing plate 31 is located to the left of the placement hole 15. A sealing gasket 32 ​​is provided at the right end of the sealing plate 31. The right end of the sealing gasket 32 ​​abuts against the left outer wall of the curing chamber 2. Several traction springs 33 and guide plates 34 are fixedly connected to the right inner wall of the hinge frame 29. Several guide grooves 35 are opened at the front end of the guide plate 34. The traction spring 33 is located in the guide groove 35. The left end of the traction spring 33 is fixedly connected to the right end of the hinge plate 30. The traction spring 33 is always in a stretched state. When the moving plate 10 is in the leftmost position, the traction spring 33 applies a traction force to the hinge plate 30 in the direction of the curing box 2, thereby ensuring that the sealing gasket 32 ​​on the right side of the sealing plate 31 can be tightly fitted with the left end of the curing box 2, thereby sealing the placement hole 15, preventing heat loss and preventing external dust from entering the curing box 2. A push plate 28 is provided on the left side of the hinge plate 30. The right end of the push plate 28 abuts against the left end of the hinge plate 30. A U-shaped connecting frame 27 is fixedly connected to the left end of the push plate 28. The front end of the connecting frame 27 is fixedly connected to the rear end of the moving plate 10. The distance between the upper and lower inner walls of the connecting frame 27 is greater than the distance between the upper and lower inner walls of the sealing plate 31. When the support plate 11 extends to the inner side of the protective frame 16, the sealing plate 31 is located inside the connecting frame 27. The abutment of the push plate 28 with the hinge plate 30 is located behind the hinge of the hinge frame 29 and the hinge plate 30. A sealing ring 14 is fixedly connected to the right side of the movable plate 10. Several support plates 11 are located inside the sealing ring 14. A placement groove 12 is opened at the upper end of the support plate 11, and a vent hole 13 is opened at the bottom of the placement groove 12. A reinforcing rod 8 is fixedly connected to the upper end of the auxiliary plate 6. The right side of the lower surface of the reinforcing rod 8 is fixedly connected to the upper end of the curing box 2. After the support plate 11 containing the product to be cured is placed in the placement groove 12 and enters the protective frame 16, a force is applied to the right side of the movable plate 10 under the action of the electric push rod 7. By squeezing the sealing ring 14, the placement hole 15 is sealed, thus preventing heat loss during the curing process. The temperature control mechanism includes a control box 3 fixed at the lower end of the operating table 1, a hot air blower 4, and a cold air blower 5. The control box 3 contains a control module. The hot air blower 4, cold air blower 5, temperature monitoring sensor 18, main solenoid valve 36, circulation solenoid valve 37, external air intake solenoid valve 38, and electric push rod 7 are all electrically connected to the control module. The output ends of the hot air blower 4 and cold air blower 5 are respectively connected to a hot air intake pipe 22 and a cold air intake pipe 23. A main solenoid valve 36 is installed on both the hot air intake pipe 22 and the cold air intake pipe 23. The input end of the cold air blower 5 is connected to an intake pipe 26. The input end of the hot air blower 4 is connected to a circulation pipe 24. The end of the circulation pipe 24 furthest from the hot air blower 4 is connected to the curing chamber 2. A circulation solenoid valve 37 is installed on the circulation pipe 24. An intake pipe 25 is connected to the circulation pipe 24. The connection point between the intake pipe 25 and the circulation pipe 24 is located between the circulation solenoid valve 37 and the hot air blower 4. An external air intake solenoid valve 38 is installed on the 5th floor. During use, the hot air blower 4 is used to preheat the curing chamber 2. After the product is placed in the protective frame 16, the hot air blower 4 can continuously regulate the temperature. At the same time, the circulation pipe 24 ensures that the input end of the hot air blower 4 can input high-temperature air, avoiding the waste of resources by drawing in cold air for heating. After curing is completed, the main solenoid valve 36 and the circulation solenoid valve 37 on the hot air blower 4 are closed, and the main solenoid valve 36 on the cold air inlet pipe is opened. The cold air blower 5 is used to slowly introduce cold air into the curing chamber 2. The temperature inside the curing chamber 2 is gradually reduced according to the cooling requirements of the curing equipment, and the temperature monitoring sensor 18 is used for real-time monitoring. When the temperature inside the curing chamber 2 reaches the basic temperature at which the product can freely enter and exit, the cold air blower 5 is stopped, and the support plate 11 on the right side of the moving plate 10 can be pulled out from the protective frame 16 using the electric push rod 7. A transparent observation window 9 is provided on the front side of the curing chamber 2, which allows operators to easily understand the situation inside the curing chamber 2.

[0020] Working principle: Before use, the moving plate 10 is located on the far left. The sealing plate 31 and sealing gasket 32 ​​seal and block the placement hole 15 under the action of the traction spring 33. Open the main solenoid valve 36, the external air intake solenoid valve 38, and the circulation solenoid valve 37 on the hot air intake pipe 22. Use the hot air blower 4 to introduce hot air into the curing chamber 2, thereby increasing the base temperature inside the curing chamber 2. After the temperature stabilizes, close the external air intake solenoid valve 38. The operator places the product to be processed in the placement slot 12 and uses the electric push rod 7 to push the moving plate 10 and several support plates 11 to the right. During the movement, the push plate 28 pushes the hinge plate 30 and the sealing plate 31 to flip. When flipped to 90 degrees, the placement hole 15 is fully exposed without affecting the support. As plate 11 is inserted, the electric push rod 7 continues to push, and the support plate 11 and the product are completely inserted into the protective frame 16. At the same time, the moving plate 10 uses the sealing ring 14 to seal the position of the placement hole 15 to prevent heat dissipation. According to the curing requirements, the hot air blower 4 is used to improve the curing process. When hot air is introduced, it enters the curing chamber 2 through the air outlet 20 and enters the protective frame 16 through the connecting holes 17 on the upper, lower and right side walls of the protective frame 16. The positions of the protective frame 16 and the air inlet frame 19 are designed to effectively prevent the hot air from directly hitting the coating. The vent hole 13 at the bottom of the support plate 11 placement groove 12 ensures that the coating on the inner surface of the sealing ring 14 can fully contact the heat flow. During the curing process, the temperature inside the curing chamber 2 is monitored in real time by the temperature monitoring sensor 18.

[0021] After curing is complete, close the main solenoid valve 36 and circulation solenoid valve 37 on the hot air blower 4, open the main solenoid valve 36 on the cold air inlet pipe, and slowly introduce cold air into the curing chamber 2 using the cold air blower 5. Gradually reduce the temperature inside the curing chamber 2 according to the cooling requirements of the curing equipment, and use the temperature monitoring sensor 18 for real-time monitoring. When the temperature inside the curing chamber 2 reaches the baseline temperature at which the product can freely enter and exit, stop the cold air blower 5. Use the electric push rod 7 to move the moving plate 10 and support plate 11 to the left. When they move to the flip... When the sealing plate 31 is rotated to the left, as the push plate 28 continues to move to the left, the traction spring 33 drives the hinge plate 30 and the sealing plate 31 to flip to the front of the placement hole 15. When the moving plate 10 moves to the leftmost side, the product can be removed. At the same time, the sealing plate 31 and the sealing gasket 32, in cooperation with the traction spring 33, seal the placement hole 15 again, thereby preventing heat loss in the curing chamber 2 when the product is removed, and effectively blocking external dust from entering the curing chamber 2, thus preventing dust from adhering to the surface of the uncured coating and forming impurities and defects.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
