[0031] 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.

[0032] Please see Figures 1-6 As shown, this utility model provides a technical solution: a hot air oven for the production of thermoplastic honeycomb panels, including a hot air oven body 1, an inner liner 2 in the middle of the hot air oven body 1, a honeycomb panel bearing assembly 3 on the inner side of the inner liner 2, and honeycomb panel heating assemblies 4 on the left and right sides of the inner liner 2. The honeycomb panel heating assemblies 4 include air inlets 401 installed on the left and right sides of the inner liner 2, hot air circulation fans 402 installed on the inner side of each air inlet 401, electric heating tubes 403 on the outer side of the hot air circulation fans 402, and air distribution covers 404 on the outer side of the electric heating tubes 403. A temperature sensor 405 is installed on the upper left front end of the inner liner 2.

[0033] Furthermore, the honeycomb panel support assembly 3 includes a limiting slide groove 301 that is set at the bottom inner side of the inner liner 2. A heating rack 302 is set inside the inner liner 2. Each heating rack 302 is equipped with a moving wheel 303 on its lower side. The moving wheel 303 is connected to the limiting slide groove 301 by a slot. The limiting slide groove 301 is provided in three rows. Each row of the limiting slide groove 301 is provided with two sets of moving wheels 303. When it is needed, the heating rack 302 containing the honeycomb panel is sent into or pulled out of the inner liner 2. The heating rack 302 can be moved flexibly along the limiting slide groove 301 by the moving wheel 303, thereby realizing a quick loading and unloading operation.

[0034] Furthermore, the inner surface of the hot drying rack 302 is welded with limiting grooves 304, and the middle of each limiting groove 304 is connected to a honeycomb panel tray 305. When needed, the honeycomb panel to be dried is placed on the honeycomb panel tray 305, and then the honeycomb panel tray 305 is inserted into the hot drying rack 302 through the limiting groove 304. In this way, multiple honeycomb panels in the honeycomb panel trays 305 can be dried at the same time. After drying, the honeycomb panel tray 305 can be removed for subsequent operations. Then, a new honeycomb panel tray 305 containing honeycomb panels can be inserted into the limiting groove 304 to complete a new round of drying operations, which greatly improves production efficiency.

[0035] Furthermore, the hot air circulation fan 402 is welded to the air inlet 401. The hot air circulation fan 402 is arranged in two sets, and the hot air circulation fan 402 and the air inlet 401 are symmetrically arranged on the left and right sides of the inner liner 2 of the box. When it is needed, the air entering from the air inlet 401 enters the inner liner 2 of the box. At this time, after the air is heated by the electric heating tube 403, the hot air circulation fan 402 will blow away the hot air lingering near the electric heating tube 403, thereby accelerating the flow speed of the hot air and ensuring that the temperature is evenly distributed throughout the entire box.

[0036] Furthermore, the electric heating element 403 and the hot air circulation fan 402 are symmetrically arranged on the left and right sides. The electric heating element 403 and the temperature sensor 405 are electrically connected. When needed, the temperature sensor 405 will sense the temperature of the inner chamber 2 in real time, and then control the electric heating element 403 to heat up, thereby maintaining a constant temperature inside the chamber. Due to the precise control of the temperature sensor 405, the entire drying process becomes more stable and reliable, avoiding the impact of temperature fluctuations on the quality of the honeycomb panel.

[0037] Furthermore, the air distribution hood 404 corresponds one-to-one with the electric heating tube 403. The air distribution hood 404 has a steel mesh structure. When needed, the air distribution hood 404 can evenly distribute the hot air blown by the hot air circulation fan 402 into the entire chamber. This not only improves the efficiency of hot air use, but also ensures that the honeycomb panels on each honeycomb panel tray 305 can receive uniform hot air drying, further improving the drying quality and efficiency. The porous structure can also prevent the air blown by the hot air circulation fan 402 from directly hitting the honeycomb panels and causing damage.

[0038] Furthermore, a circulating fan 406 is installed on the top inner side of the inner liner 2 of the box, and an air guide 407 is welded above the circulating fan 406. When needed, the circulating fan 406 will draw air from the inner liner 2 of the box, thereby timely removing the air carrying moisture and avoiding the impact of moisture on the drying quality of the honeycomb panel. The circulating fan 406 and the air guide 407 work together to achieve air circulation.

[0039] Working principle: When needed, first place the hot air drying oven body 1 in the desired position, then place the honeycomb panels to be dried on the honeycomb panel tray 305. Next, insert the honeycomb panel tray 305 into the limiting groove 304 within the drying rack 302. Then, slide the drying rack 302 into the inner chamber 2 via the casters 303. The limiting groove 301 limits the movement of the casters 303. Finally, close the oven door. The equipment then begins operation. The temperature sensor 405 senses temperature changes in real time and controls the electric heating element 403 according to the temperature requirements. The air is heated, and the hot air circulation fan 402 blows hot air into the inner chamber 2 of the chamber through the air inlet 401. The cold air entering through the air inlet 401 is reheated by the electric heating tube 403. As the hot air is blown into the inner chamber 2, it is dispersed by the air distribution shroud 404, thereby reducing the wind speed and making the temperature inside the inner chamber 2 more uniform. Finally, the hot air carrying moisture is drawn out by the circulating fan 406 and discharged through the air duct 407. This completes the process of using a hot air drying oven for the production of thermoplastic honeycomb panels.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
