[0019] The following will further describe the present utility model with reference to the drawings in the specification.

[0020] The present utility model provides the following technical solutions:

[0021] As attachedFigures 1-4 As shown in the figure, the utility model discloses a shoe machine oven, which includes an oven body 1. A heating chamber 2 is formed inside the oven body 1. A partition is arranged inside the heating chamber 2. The partition includes an upper partition 3 and a lower partition 4. The lower partition 4 is arranged below the upper partition 3. The upper partition 3 and the lower partition 4 are fixedly connected. The outer edge of the upper partition 3 is fixedly connected to the inner wall of the heating chamber 2 to divide the heating chamber 2 into an upper chamber part 5 and a lower chamber part 6. An inlet and outlet 7 is formed between the lower partition 4 and the inner wall of the heating chamber 2. An intermediate air duct 8 is arranged between the upper partition 3 and the lower partition 4. The intermediate air duct 8 is communicated with the inlet and outlet 7. A communication port communicating with the intermediate air duct 8 and a side air outlet 9 communicating with the lower chamber part 6 are respectively opened on the upper partition 3. Specifically, in this design, by arranging the inlet and outlet 7 between the lower partition 4 and the inner wall of the heating chamber 2, the hot air generated by the heating element 10 in the lower chamber part 6 can enter the intermediate air duct 8 communicated with the inlet and outlet 7 through the inlet and outlet 7, and then enter the inside of the air wheel 11 from the intermediate air duct 8. During the rotation of the air wheel 11, the hot air inside the air wheel 11 enters the upper chamber part 5 through the air outlet groove 15, and then enters the lower chamber part 6 through the side air outlet 9 to realize the hot air circulation, generating a wind curtain effect, effectively blocking the overflow of the hot air inside the oven and the entry of the external cold air into the oven, achieving the energy-saving effect, thereby achieving the uniform heating effect, and retaining the heat, so that the temperature inside the heating chamber 2 will not lose too fast, and thus there is no need to increase the power of the heating element 10, reducing the electricity cost.

[0022] Furthermore, a plurality of heating elements 10 are arranged inside the lower chamber part 6. The heating elements 10 are all arranged at equal intervals along the length direction of the lower partition 4 below the lower partition 4. The two ends of the heating element 10 are fixedly connected to the inside of the lower chamber part 6. Specifically, in this embodiment, the heating element 10 is an infrared electric heating tube. By reasonably arranging the infrared electric heating tubes, it can ensure that the heat is evenly distributed throughout the lower chamber part 6. The use of the infrared electric heating tube not only improves the heating efficiency, but also has a long service life and low maintenance cost. In addition, the heat radiation characteristic of the infrared electric heating tube makes the heating process softer, avoiding the direct high-temperature impact on the shoe material, thereby protecting the quality of the shoe material.

[0023] Further, the communication port is opened at the center position of the upper partition plate 3. A wind wheel 11 is arranged at a position corresponding to the communication port on the upper partition plate 3 within the upper cavity portion 5. A part of the upper partition plate 3 near the edge of the communication port protrudes to form a wind wheel connection end 12. The wind wheel connection end 12 extends into the interior of the wind wheel 11 to be connected to the wind wheel 11. A wind wheel power source 13 is arranged on the oven body 1. One end of the wind wheel power source 13 extends into the upper cavity portion 5 to be connected to the wind wheel 11. Specifically, in this embodiment, the wind wheel power source 13 is a motor. The wind wheel power source 13 has an output shaft 14. A connection hole is arranged on the wind wheel 11. The output shaft 14 extends into the connection hole to drive the wind wheel 11 to rotate, thereby realizing the circulation of hot air between the middle air duct 8 and the upper and lower cavity portions 6. The use of the motor ensures the stable operation of the wind wheel 11. At the same time, the power of the motor can be adjusted according to actual needs, further optimizing the energy consumption.

[0024] Further, a clearance fit is adopted between the wind wheel 11, the upper partition plate 3 and the wind wheel connection end 12. Specifically, in this embodiment, a clearance fit is adopted between the wind wheel 11, the upper partition plate 3 and the wind wheel connection end 12, ensuring that the wind wheel 11 will not rub against the upper partition plate 3 during operation, thereby reducing noise and prolonging the service life of the equipment.

[0025] Further, the side air vents 9 are opened at least at the center positions of the symmetric two sides of the upper partition plate 3. Specifically, in this embodiment, the side air vents 9 are evenly distributed at the center positions of the two sides of the upper partition plate 3, ensuring that the hot air can evenly flow from the upper cavity portion 5 to the lower cavity portion 6. This design not only improves the heating efficiency but also ensures a more uniform temperature distribution within the entire heating cavity 2. By precisely controlling the size and number of the side air vents 9, the flow path of the hot air can be further optimized, thereby realizing the precise heating of the shoe material.

[0026] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
