[0030] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0031] Refer to Figure 1-2 , an embodiment provided by the present utility model: An electrothermal drying system for an automatic roll forming machine, including an electrothermal drying system 12 and a body 13 of the roll forming machine. The electrothermal drying system 12 includes a plurality of air ducts 1, a fan 9 and an electric heating box 10. A second air inlet 7 is fixedly arranged on one side of the electric heating box 10. A second air valve 8 is fixedly arranged at the upper end of the second air inlet 7. A first air valve 6 is fixedly arranged at the lower end of the second air inlet 7. A return air duct 5 is fixedly arranged at the lower end of the first air valve 6;

[0032] An air outlet 11 is fixedly arranged on the front end face of the electric heating box 10. A plurality of air dampers 3 are fixedly arranged on the lower end face of the air outlet 11. A plurality of small air outlets 2 are opened on the lower end faces of the plurality of air ducts 1. A first air inlet 4 is fixedly arranged on one side of the upper end faces of the plurality of air ducts 1.

[0033] Specifically, according to the above embodiment, the air outlet end of the fan 9 is connected to the electric heating box 10.

[0034] It can be known that when using the electric heating system, the upper end of the second air valve 8 is not connected to a pipeline. The second air valve 8 is opened, and at this time, the first air valve 6 is closed. When the fan 9 is started and the fan 9 is working, air enters from the second air valve 8 to the second air inlet 7, then enters the electric heating box 10 through the fan 9. After the resistance wire in the electric heating box 10 heats up to increase the temperature of the passing air, it is discharged through multiple air gates 3 at the lower end of the air outlet 11. Since the multiple air gates 3 and the multiple first air inlets 4 are connected by high-temperature resistant hoses, the hot air discharged from the air gates 3 is promoted to enter the air duct 1, and then is blown to the blank through the small air outlets 2 evenly arranged at the lower end of the air duct 1, so as to achieve the purpose of drying the blank. Embodiment

[0035] Specifically, according to the above technical solution, the upper end of the second air valve 8 is connected to a kiln waste heat pipeline. The hot air in the kiln waste heat pipe can be introduced into the fan 9 for secondary utilization and heating, so as to realize the utilization and discharge of waste heat to achieve drying, realize the waste heat utilization function, and reduce the power consumption required for heating the electric heating box 10.

[0036] Specifically, a support frame is fixedly arranged at the upper end of the rolling forming machine body 13, and the electric heating and drying system 12 is fixedly arranged at the upper end of the support frame. There is a heat preservation cavity arranged at the upper end of the rolling forming machine body 13, and a blank is arranged in the heat preservation cavity. A temperature sensor and a humidity sensor are arranged in the heat preservation cavity. It can be known that installing the electric heating and drying system 12 at the upper end of the rolling forming machine body 13 can achieve the effect of rapid blowing and drying. And because the blank is in a heat preservation cavity sealed on all sides, and a temperature sensor is arranged inside the cavity. When the temperature in the cavity is lower than the set temperature, the electric heating system will automatically start heating to make the temperature in the cavity reach a constant temperature. When the humidity in the cavity is relatively high, the first air valve 6 will be opened, and the air in the cavity will enter the electric heating box 10 through the return air duct 5, and then be blown to the blank after heating, forming a cycle, so as to achieve the purpose of reducing humidity.

[0037] Working principle: When the electric heating system is in use, the fan 9 works to draw air from the second air valve 8 to the second air inlet 7, enters the electric heating box 10 through the fan 9, and the resistance wire heats up to increase the temperature of the passing air. The air enters the first air inlet 4 through the air gate 3 at the air outlet 11, and then is blown to the blank through the small air outlets 2 evenly arranged at the lower end of the air duct 1, so as to achieve the purpose of drying the blank.

[0038] 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 on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
