[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: An electrothermal forced-air drying oven with uniform drying includes a drying chamber 1. A chamber door 2 is rotatably connected to the outer wall of the drying chamber 1. The chamber door 2 is used to facilitate the operator to put in or take out the drying material, providing good sealing performance and a convenient operation space. A fixed rod 3 is fixedly connected inside the drying chamber 1. The fixed rod 3 serves as a support structure to ensure the stability of other components. A frame 4 is arranged inside the fixed rod 3. The frame 4 plays a role in support and positioning, ensuring the fixation and reasonable layout of the internal structure, enhancing the reliability of the equipment. An adjustment component is arranged inside the drying chamber 1 for realizing precise control of the air volume and air flow during the drying process;

[0022] The adjustment assembly includes a fixed ring 6, the outer wall of the fixed ring 6 is fixedly connected inside the drying box body 1. After the fixed ring 6 is fixed, it can provide stable support to ensure the accuracy of subsequent adjustment operations and the durability of the equipment. A fan 5 is fixedly connected inside the drying box body 1. As an important component for air circulation, the fan 5 generates hot air by rotating, pushing the air to flow evenly inside the box, thereby realizing the uniform drying of the material. A limiting component is arranged inside the fixed ring 6, and the function of the limiting component is to ensure the correct positioning and rotation of the baffle 12. A support 9 is fixedly connected to the outer wall of the fixed ring 6, and the support 9 provides the support positions for the baffle 12 and the rotating shaft 11 to ensure the structural stability. A rotating shaft 11 arranged in a circular array is rotatably connected inside the fixed ring 6. The rotating shaft 11 adjusts the position of the baffle 12 by rotating, thereby changing the direction of the air flow and controlling the air flow distribution inside the drying box to make the drying process more uniform. A baffle 12 is fixedly connected to one end of each rotating shaft 11. The baffle 12 can adjust the direction and intensity of the air flow by rotating, effectively improving the drying effect. Connecting rods 14 are fixedly connected to the outer walls of the rotating shafts 11. One end of each connecting rod 14 is rotatably connected to a universal shaft 15. The rotation of the universal shaft 15 can ensure the synchronous adjustment of each baffle 12, avoiding the problem of uneven air flow inside the drying box. A driving component is arranged on one side of the support 9. The driving component is powered by a motor 10. The outer wall of the motor 10 is fixedly connected to one side of the support 9. The output end of the motor 10 is connected to one end of the rotating shaft 11 to drive the rotating shaft 11 to rotate, thereby driving the baffle 12 to adjust the air flow and ensuring the adjustment of the air volume and the air flow direction inside the drying box. A heating wire 21 is arranged between the fan 5 and the fixed ring 6, so that the heating wire 21 generates heat, and the air is heated by the fan 5 and blown into the drying box body 1.

[0023] Refer to Figure 4 and Figure 5, a positioning groove 7 arranged in a linear array is formed inside the fixed rod 3. The setting of the positioning groove 7 can provide an accurate sliding track for the frame 4, enabling the frame 4 to slide smoothly along a straight line direction. A positioning hole 8 arranged in a linear array is formed inside the fixed rod 3. The positioning hole 8 cooperates with the hemispherical column 18 of the frame 4 to provide a fixed positioning point, preventing the frame 4 from shifting or being unstable during operation. The frame 4 is slidably connected inside the positioning groove 7. Guided by the positioning groove 7, the frame 4 can slide smoothly inside the fixed rod 3, ensuring the stability of the internal structure of the drying oven. A limiting groove 16 is formed inside the frame 4. The function of the limiting groove 16 is to limit the sliding range of the limiting plate 17 inside the frame 4, ensuring that the movement range of the frame 4 does not exceed the predetermined range, increasing the safety of use. A limiting plate 17 is arranged inside the frame 4. The limiting plate 17 is slidably connected inside the limiting groove 16. The limiting plate 17 is responsible for ensuring the stability and accurate positioning of the frame 4. A hemispherical column 18 is fixedly connected to one side of the limiting plate 17. The hemispherical column 18 is fitted with the positioning hole 8 to form a reliable positioning connection, making the relative movement between the frame 4 and the fixed rod 3 more accurate and avoiding equipment abnormalities caused by inaccurate positioning. A telescopic rod 19 is arranged inside the frame 4. The telescopic rod 19 can be telescopically adjusted inside the frame 4, thereby adjusting the position of the frame 4. A spring 20 is sleeved on the outer wall of the telescopic rod 19. The function of the spring 20 is to ensure that the telescopic rod 19 can reset to the predetermined position when needed through its elastic restoring force, ensuring the stability and efficient operation of the system. One ends of the telescopic rod 19 and the spring 20 are both fixedly connected inside the frame 4, and the other ends are fixedly connected to the limiting plate 17, ensuring the supporting effect of the telescopic rod 19 and making the movement of the frame 4 smoother and more accurate.

[0024] Working principle: When using this electrothermal blast drying oven for uniform drying, first, when installing the frame 4, the frame 4 is directly slid into the positioning groove 7 on the fixed rod 3. Multiple positioning grooves 7 are arranged on the fixed rod 3, and the position of the frame 4 on the fixed rod 3 can be adjusted arbitrarily. Subsequently, the hemispherical column 18 inside the frame 4 is embedded into the positioning hole 8 to fix the frame 4 on the fixed rod 3. The hemispherical column 18 is slidably limited inside the limiting groove 16 through the limiting plate 17 and supported by the tension of the spring 20, enabling the hemispherical column 18 to be stably fitted inside the positioning hole 8, achieving the effect of facilitating the positioning of the frame 4;

[0025] When it is necessary to dry the products inside the drying box 1, heat is generated by heating wire 21 inside the drying box 1. Subsequently, the fan 5 sucks in the air inside the drying box 1, and then accesses the inside of the drying box 1 through the fixing ring 6 for drying. When it is necessary to adjust the air intake, the output end of the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the baffle 12 to rotate. One end of the baffle 12 is limited inside the fixing ring 6 through the limiting column 13. At the same time, the connecting rod 14 on the outer wall of the rotating shaft 11 drives the universal shaft 15 to rotate synchronously. Each baffle 12 is connected through the universal shaft 15. Therefore, when one baffle 12 rotates, the other baffles 12 rotate synchronously, thereby adjusting the opening and closing angle of the baffle 12, achieving the effect of adjusting the air intake.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
