[0027] Two support plates 10 are fixedly installed at the bottom of the upper side of the main body 1 of the electric kiln heating device. The two support plates 10 are threaded with first bolts 11. A horizontal plate 12 is fixedly connected to one side of the two first bolts 11. An arc plate 13 for clamping the heating rod 2 is connected in an array to one side of the two horizontal plates 12. Through the installation and use of the arc plate 19 and the arc plate 13, the two arc plates can be attached to the heating rod 2 to clamp and position the heating rod 2. Two sliding rods 14 are fixedly connected to the other side of the two horizontal plates 12. A top cover plate 3 is snapped onto the upper side of the main body 1 of the electric kiln heating device.

[0028] The upper side of the main body 1 of the electric kiln heating device is provided with four L-shaped grooves 4. Each of the four L-shaped grooves 4 is slidably engaged with an L-shaped block 5 for fixing the top cover plate 3. The rear side of the main body 1 of the electric kiln heating device is threaded with two second bolts 17 for fixing the top cover plate 3. The upper side of the top cover plate 3 is engaged with two snap-fit ​​grooves 18, which can be used to open the top cover plate 3, making it convenient to use. A heat preservation box 25 is fixedly connected to one side of the main body 1 of the electric kiln heating device. The heat preservation box 25 is made of polystyrene and polyurethane to reduce the heat loss inside the heat preservation box 25.

[0029] An air inlet pipe 26 is fixedly connected to one side of the insulation box 25, and an air outlet pipe 27 is fixedly connected to the other side of the insulation box 25. Both the air inlet pipe 26 and the air outlet pipe 27 pass through the main body 1 of the electric kiln heating device and extend into the interior of the main body 1 of the electric kiln heating device. The air inlet pipe 26 and the air outlet pipe 27 are distributed vertically. A baffle rod 28 is rotatably connected to one side of the interior of the main body 1 of the electric kiln heating device. A sealing plate 29 is fixedly connected to one side of the baffle rod 28. A servo motor is fixedly installed on one side of the main body 1 of the electric kiln heating device.

[0031] Both round rods 19 have sliders 20 slidably connected to their outer surfaces. A base plate 21 is fixedly installed on the upper side of the two sliders 20. A handle 24 is fixedly connected to one side of the base plate 21. Two symmetrically distributed U-shaped seats 22 are fixedly connected to the lower side of the base plate 21. Rollers 23 for moving the base plate 21 are rotatably connected inside the two U-shaped seats 22. The base plate 21 can be used to place the workpiece to be heated. With the rollers 23, the base plate 21 can be moved out of the electric kiln heating device, saving time and effort and avoiding the need to reach into the electric kiln heating device to retrieve the workpiece. The two sliders 20 can move on the two round rods 19 to limit the movement trajectory of the base plate 21 and ensure the stability of the base plate 21 when it moves.

[0032] A side plate 7 is fixedly installed on one side of the support base 6. The heating rod 2 passes through the main body 1 of the electric kiln heating device and extends to the bottom of the upper side of the main body 1 of the electric kiln heating device. The outer surfaces of the two slide rods 14 are slidably placed inside the support plate 10. The two slide rods 14 can limit and guide the movement trajectory of the horizontal plate 12, so that the arc plate 13 can move and adjust smoothly for clamping the heating rod 2.

[0033] The working principle of the electric kiln heating device provided by this utility model is as follows:

[0034] By pressing the side plate 7, the support seat 6, which is equipped with the connecting spring 8, can move downwards. Then, the heating rod 2 is placed on the support seat 6, and the heating rod 2 is then snapped into the top of the electric kiln heating device body 1. At this time, the elastic support seat 6 is released to initially position the heating rod 2. Then, the first bolt 11 is rotated in sequence, which moves the horizontal plate 12 for adjustment. This allows the second arc plate 13 on the horizontal plate 12 to move to the heating rod 2. Combined with the use of the first arc plate 9, the two arc plates can clamp the heating rod 2 together, ensuring the heating rod 2 is securely installed. Stability is ensured by using support base 6, arc plate 1 9 and arc plate 2 13 to conveniently clamp and support heating rod 2, which facilitates quick loading and unloading of heating rod 2. The operation is simple, time-saving and labor-saving, improving the efficiency of loading and unloading heating rod 2 in electric kiln heating device. At the same time, L-shaped block 5 and second bolt 17 can be used to fix top cover plate 3 above electric kiln heating device body 1. In this way, second polyurethane foam 16 at top cover plate 3 can be snapped into the inside of first polyurethane foam 15. In this way, polyurethane foam can increase the heat insulation effect of top cover plate 3 and prevent the loss of heating heat.

[0035] By rotating the baffle rod 28 through the output shaft of the servo motor, the baffle rod 28 can simultaneously seal the air inlet pipe 26 and the air outlet pipe 27. Then, the heating rod 2 is energized to generate high temperature, so as to transfer heat to the workpiece inside the electric kiln heating device body 1. When the heating work is finished, the baffle rod 28 drives the sealing plate 29 to rotate and adjust to seal the air outlet pipe 27. In this way, the heat can enter the heat preservation box 25 through the air inlet pipe 26 for temporary storage. Then, the baffle rod 28 seals the air inlet pipe 26 and the air outlet pipe 27 to prevent the heat from dissipating. When the heating work is about to begin, the baffle rod 28 can drive the sealing plate 29 to seal the air inlet pipe 26, so that the heat from the heat preservation box 25 can enter the electric kiln heating device body 1 through the air outlet pipe 27. This reuse of the heat inside the electric kiln heating device allows the electric kiln heating device to heat up quickly and improves the processing efficiency of the electric kiln heating device.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
