[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1, refer to Figures 1-2 An embodiment of this utility model provides a heat insulation cover for a fan wheel in an aging oven, comprising a connecting plate 1, a first connecting plate 4 on the top of the connecting plate 1, a second connecting plate 5 fixedly connected to the top of the first connecting plate 4, a servo motor 6 fixedly connected to the inner wall of the second connecting plate 5, connecting holes 13 evenly opened on the surface of the connecting plate 1, a protective shell 2 attached to the bottom of the connecting plate 1, heat insulation cotton 10 inside the protective shell 2, a sealing ring 9 fixedly connected to the bottom of the protective shell 2, a connecting ring 8 attached to the bottom of the protective shell 2, a fan wheel 7 threadedly connected to the inner wall of the connecting ring 8, a protective cover 3 attached to the outer wall surface of the sealing ring 9, a groove 15 opened on the surface of the connecting plate 1, and a connecting mechanism 11 provided on the surface of the groove 15; Specifically, the heat insulation cotton 10 built into the protective shell 2 can prevent heat loss inside the aging oven, ensure stable temperature in the air duct, and not affect the normal rotation of the servo motor 6. Meanwhile, by filling the gap between the protective shell 2 and the protective cover 3 with the sealing ring 9, the connection between the protective shell 2 and the protective cover 3 is sealed, thereby reducing the loss of heat from the connection between the protective shell 2 and the protective cover 3 and ensuring the temperature stability inside the air duct. In addition, the bolts in the connecting hole 13 enable the connecting plate 1 and the protective cover 3 to be fixed through the protective shell 2, thereby achieving modular connection and facilitating subsequent disassembly and maintenance.

[0019] Reference Figures 3-4The connecting mechanism 11 includes a connecting bushing 14, the surface of the connecting bushing 14 is in contact with the inner wall surface of the groove 15, and connecting curved surfaces 20 are provided on both the left and right sides of the connecting bushing 14, with pins 18 attached to the surface of the connecting curved surfaces 20. Specifically, the connecting bushing 14 is made stable inside the groove 15 by fitting with the groove 15, and the connecting bushing 14 can be fixed by the pin 18 to prevent the connecting bushing 14 from being displaced due to vibration or external force during the operation of the aging oven. During maintenance, the connecting bushing 14 can be disassembled and reset by removing or installing the pin 18, which improves the convenience of oven maintenance.

[0020] Reference Figure 1 The surface of the first connecting plate 4 is evenly provided with fixing holes, and screws are threaded to the inner wall of the fixing holes. The screws are threaded to the connecting plate 1, the first connecting plate 4 and the second connecting plate 5. Specifically, the fixing holes allow the screws to be evenly distributed on the first connecting plate 4, preventing structural deformation due to concentrated force.

[0021] Reference Figure 4 A fixing block 16 is fixedly connected to one side of the inner wall of the groove 15, and a positioning block 17 is fixedly connected to the other side of the inner wall of the groove 15. The surface of the pin 18 is respectively attached to the inner walls of the fixing block 16 and the positioning block 17. Specifically, pins 18 are provided on both the left and right sides of the connecting bushing 14. The pins 18 penetrate and extend to the outside of the positioning block 17. The pins 18 are initially positioned by the fixing block 16. Through the combined action of the fixing block 16 and the positioning block 17, the position of the pins 18 can be limited from both sides, thereby preventing the pins 18 from sliding laterally or shifting longitudinally in the groove 15.

[0022] Reference Figure 4 The inner wall of the pin 18 is slidably connected to a fixed cylinder 19, and the top of the positioning block 17 has a round hole, with the fixed cylinder 19 fitting against the inner wall of the round hole. Specifically, after the pin 18 is limited by the fixing block 16 and the positioning block 17, the fixing cylinder 19 is embedded in the round hole and fits against the inner wall to further limit the pin 18, thereby preventing the pin 18 from coming out of the fixing block 16 and the positioning block 17, further strengthening the positioning effect of the pin 18 on the connecting bushing 14, and ensuring that the connecting bushing 14 is stably fixed in the groove 15.

[0023] Reference Figures 1-2 The inner wall of the connecting hole 13 is threaded with a bolt, which is threadedly connected to the protective shell 2 and the protective cover 3, and the bottom surface of the protective shell 2 is in contact with the top of the protective cover 3. Specifically, by fixing the connecting plate 1, protective shell 2, and protective cover 3 with bolts, the forces on the three can be transmitted and dispersed to each other, avoiding deformation of a single component due to independent load bearing, and preventing the protective shell 2 or protective cover 3 from loosening or shifting due to external forces.

[0024] Reference Figures 1-2 The output end of the servo motor 6 is fixedly equipped with a rotor, and the rotor surface is threadedly connected to the connecting ring 8. Specifically, the rotor is threadedly connected to the connecting ring 8, and the inner wall of the connecting ring 8 is threadedly connected to the impeller 7, so that the rotation of the rotor can drive the connecting ring 8 and the impeller 7 to rotate synchronously, thereby forming a power transmission path.

[0025] Example 2, refer to Figure 2 The connecting mechanism 11 also includes a guide 12, which is fixedly connected to the connecting plate 1, and the top surface of the guide 12 is in contact with the bottom surface of the first connecting plate 4; Specifically, during the assembly of the servo motor 6, the guide 12 can guide the position of the first connecting plate 4 to prevent the first connecting plate 4 from shifting position, thereby ensuring the accurate installation position of the second connecting plate 5 and the servo motor 6.

[0026] Working principle: The output ends of both the impeller 7 and the servo motor 6 are threaded to the connecting ring 8, which facilitates the disassembly and maintenance of the servo motor 6 and the impeller 7. The heat insulation cotton 10 inside the protective shell 2 is fixed above the impeller 7 by the connecting plate 1, forming a physical barrier to prevent the hot air in the air duct from directly contacting the outside. At the same time, the protective shell 2 can protect the heat insulation cotton 10, further reducing the loss of heat from the installation gaps of the servo motor 6 or the impeller 7. The output end of the servo motor 6 is rotatably connected to the inner wall of the connecting bushing 14. Both sides of the connecting bushing 14 are provided with connecting curved surfaces 20. The connecting bushing 14 can be positioned on the top of the connecting plate 1 by means of pins 18. The pins 18 can be fixed by means of fixing cylinders 19, thereby reducing the complexity of maintenance and repair.
