Description

Technical Field

[0001] This utility model relates to the field of aerogel thermal insulation felt processing technology, specifically an adaptive roller coating device for aerogel thermal insulation felt. Background Technology

[0002] Aerogel insulation felt is a high-performance thermal insulation material. It is made of nano-silica or metal aerogel as the main material and is compounded with carbon fiber, ceramic glass fiber cotton or pre-oxidized fiber felt through a special process. It has the characteristics of low thermal conductivity, moderate tensile and compressive strength, softness and easy cutting, low density, inorganic fire resistance, overall hydrophobicity, and green environmental protection.

[0003] In the production and processing of existing aerogel thermal insulation felts, a coating needs to be applied to the material surface, requiring the use of a corresponding roller coating device. In practical use, existing roller coating devices spray the coating onto the substrate surface using a nozzle, and then rotate a roller to achieve uniform rolling of the coating onto the moving substrate surface. However, in actual operation, at low temperatures, the adhesion between the rolled coating and the substrate is poor, which can easily affect the subsequent quality of the product. Furthermore, it is not convenient to introduce hot air into the inner cavity of the roller to heat the pressure area and improve the adhesion quality. Therefore, we propose a dedicated adaptive roller coating device for aerogel thermal insulation felts. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive roller coating device for aerogel thermal insulation felt, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive roller coating device for aerogel thermal insulation felt, comprising a carrier block, wherein a fixing frame is fixed to the top of the carrier block;

[0006] An electric actuator is fixed at the top center of the fixed frame. The actuator rod moves through the fixed frame and is fixedly connected to a retainer. A hollow roller is rotatably mounted inside the retainer. A hot air blower is fixedly mounted on one side wall of the fixed frame. The output end of the hot air blower is fixedly connected to a first conduit. The outer end of the first conduit is connected to a hollow short shaft through a rotary joint. The hollow short shaft passes through the retainer and is connected to the roller. The other end of the roller passes through the retainer through a rotary joint and is connected to a second conduit. A drive assembly is mounted on one side wall of the retainer. The drive assembly is used to drive the roller to rotate. A paint spray nozzle is fixedly connected to one side wall of the retainer.

[0007] By adopting the above technical solution, the substrate is attached to the top of the carrier block, and the electric actuator drives the retainer to descend, thereby causing the roller to adhere to the surface of the substrate. The paint is then sprayed onto the substrate using a paint nozzle. As the substrate moves, the drive assembly drives the roller to rotate, thereby rolling the sprayed paint. During the rolling process, a hot air blower generates hot air and guides it into the inner cavity of the roller, thereby heating the roller and giving it a certain base temperature. This allows the heat to be transferred to the paint during the rolling process, ensuring that the paint has a certain base temperature, which is beneficial for improving the adhesion quality between the paint and the substrate during the rolling process.

[0008] In a preferred embodiment of the present invention, an aluminum box is embedded in the middle of the top of the carrier block, the output end of the second conduit passes through the side wall of the carrier block and is connected to one end of the aluminum box, and the other end of the aluminum box is fixedly connected to an air outlet pipe.

[0009] By adopting the above technical solution, the residual temperature gas exported from the roller is guided into the inner cavity of the aluminum box. The heat transfer performance of the aluminum box is utilized to transfer the residual temperature of the gas to the bottom of the substrate that is attached to the top of the carrier block. This gives the substrate a certain base temperature, which is beneficial to further improve the bonding quality.

[0010] In a preferred embodiment of this utility model, the top of the inner cavity of the aluminum box is integrally formed with multiple evenly distributed heat-conducting columns.

[0011] By adopting the above technical solution, the gas introduced into the inner cavity of the aluminum box can come into contact with multiple heat-conducting columns, which helps to improve the heat conduction effect and thus improve the effect of heat transfer to the substrate.

[0012] In a preferred embodiment of the present invention, the drive assembly includes a servo motor, a first gear is fixedly connected to the outer end of the drive shaft of the servo motor, a second gear meshes with the outer wall of the first gear, and the second gear is fixedly fitted onto the outer wall of the hollow short shaft.

[0013] By adopting the above technical solution, the first gear is driven to rotate by the servo motor, which in turn drives the second gear to rotate, thereby driving the hollow short shaft to rotate, and then driving the roller to rotate, thus realizing the rolling of the coating material by using the rotating roller.

[0014] In a preferred embodiment of the present invention, limiting rods are fixed on both sides of the top of the retainer, and the limiting rods movably pass through the fixed frame.

[0015] In a preferred embodiment of this utility model, mounting plates are fixed on both sides of the two side walls of the carrier block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application provides an adaptive roller coating device for aerogel thermal insulation felt. It generates hot air through a hot air blower and guides the hot air into the inner cavity of the roller shaft, thereby giving the roller shaft a certain base temperature. During the roller coating process, the heat can be transferred to the coating, thus giving the coating a certain base temperature, which is beneficial to improving the adhesion quality between the coating and the substrate when roller coating.

[0018] By guiding the residual heat gas from the roller shaft into the inner cavity of the aluminum box, the heat transfer properties of the aluminum box are utilized to transfer the residual heat of the gas to the bottom of the substrate, thereby giving the substrate a certain base temperature, which is beneficial to further improve the bonding quality.

[0019] After the gas is introduced into the inner cavity of the aluminum box, it can come into contact with multiple heat-conducting pillars, which helps to improve the heat conduction effect and thus improve the heat transfer to the substrate. Attached Figure Description

[0028] Please see Figure 1-3This utility model provides a technical solution: an adaptive roller coating device for aerogel thermal insulation felt, including a carrier block 1, and a fixing frame 13 fixed on the top of the carrier block 1;

[0029] An electric actuator 23 is fixed at the top center of the fixed frame 13. The actuator 23 moves through the fixed frame 13 and is fixedly connected to a retainer 2. A hollow roller 21 is rotatably installed in the inner cavity of the retainer 2. A hot air blower 3 is fixedly installed on one side wall of the fixed frame 13. The output end of the hot air blower 3 is fixedly connected to a first conduit. The outer end of the first conduit is connected to a hollow short shaft 31 through a rotary joint. The hollow short shaft 31 passes through the retainer 2 and is connected to the roller 21. The other end of the roller 21 passes through the retainer 2 through a rotary joint and is connected to a second conduit. A drive assembly is installed on one side wall of the retainer 2. The drive assembly is used to drive the roller 21 to rotate. A paint spray nozzle 22 is fixedly connected to one side wall of the retainer 2.

[0030] It should be understood that in actual use, the substrate is attached to the top of the carrier block 1, and the electric actuator 23 drives the retainer 2 to descend, so that the roller 21 is attached to the surface of the substrate. The paint spray nozzle 22 is used to spray paint onto the substrate, and as the substrate moves, the drive assembly drives the roller 21 to rotate, thereby rolling the sprayed paint. During the rolling process, the hot air generated by the hot air blower 3 is guided into the inner cavity of the roller 21, thereby heating the roller 21 and giving it a certain base temperature. During the rolling process, the temperature can be transferred to the paint, thus giving the paint a certain base temperature, which is beneficial to improving the adhesion quality between the paint and the substrate when rolling the paint.

[0031] Furthermore, mounting plates 12 are fixed on both sides of the two side walls of the carrier block 1. The mounting plates 12 facilitate the overall installation and fixation of the device.

[0032] Furthermore, limit rods 24 are fixed on both sides of the top of the cage 2. The limit rods 24 are movable through the fixed frame 13. The setting of the limit rods 24 makes the electric push rod 23 drive the cage 2 to rise and fall with high stability.

[0033] like Figure 1 and 2 As shown; an aluminum box 11 is embedded in the middle of the top of the carrier block 1, the output end of the second conduit passes through the side wall of the carrier block 1 and is connected to one end of the aluminum box 11, and the other end of the aluminum box 11 is fixedly connected to an air outlet pipe.

[0034] It should be understood that by guiding the residual temperature gas from inside the roller 21 into the inner cavity of the aluminum box 11, the heat transfer performance of the aluminum box 11 is utilized to transfer the residual temperature of the gas to the bottom of the substrate that is attached to the top of the carrier block 1, thereby giving the substrate a certain base temperature, which is beneficial to further improve the bonding quality.

[0035] Furthermore, the top of the inner cavity of the aluminum box 11 is integrally formed with multiple evenly distributed heat-conducting columns 14. After the gas is introduced into the inner cavity of the aluminum box 11, it can come into contact with the multiple heat-conducting columns 14, which helps to improve the heat conduction effect and thus improve the effect of heat transfer to the substrate.

[0036] like Figure 1 and 2 As shown; the drive assembly includes a servo motor 34, the outer end of the drive shaft of the servo motor 34 is fixedly connected to a first gear 33, the outer wall of the first gear 33 is meshed with a second gear 32, and the second gear 32 is fixedly fitted onto the outer wall of the hollow short shaft 31.

[0037] It should be understood that the servo motor 34 drives the first gear 33 to rotate, which in turn drives the second gear 32 to rotate, thereby driving the hollow short shaft 31 to rotate, which in turn drives the roller shaft 21 to rotate, thus enabling the coating to be rolled using the rotating roller shaft 21.
