[0028] ​​Working principle: when the epoxy powder coating sprayed object needs to be cured at high temperature, the device can realize efficient heat treatment operation. The object is first hung into the inside of the machine body 5 by the hanging mechanism through the feed port 4 arranged at the front end of the device. In the machine body 5, the built-in battery 9 supplies power to the heating system, the heating pipe 20 starts to heat, and the fan 7 starts to inhale external air and blow it into the air box 8. The air box 8 guides the air flow through the heating pipe 20 through the internal air duct, and the high-temperature gas flow is introduced into the machine body 5 to uniformly heat the object. During long-term continuous operation, the bottom plate 2 at the bottom of the machine body 5 is easy to accumulate powder particles, dust and other impurities. In order not to affect the curing quality of the object surface, a cleaning structure is designed at the bottom of the device. By rotating the external knob 10, the baffle 11 and the connecting plate 14 connected to the knob 10 can slide on the lead screw 16 arranged at the bottom of the device to realize the clamping or loosening control of the bottom plate 2. When the bottom plate 2 is loosened, the pull ring 3 arranged on the bottom plate 2 can be pulled to quickly pull out the bottom plate 2 from the machine body 5 for cleaning and maintenance operation. This design not only improves the convenience of the device, but also effectively avoids the decline of curing quality caused by dust pollution, thereby improving the overall work efficiency and product qualification rate.

[0029] In addition, in order to improve the heat utilization rate and curing effect during the heat treatment of the object, a hot air and cold air circulation system is designed. After the fan 7 inhales air and heats it through the heating pipe 20, the high-temperature gas flow is introduced into the ventilation pipe 21 and further flows into multiple circulation channels 22 distributed in the machine body 5. The circulation channels 22 are arranged in layers and have multiple evenly distributed air outlets 25, so that the high-temperature gas can fully cover the surface of the object to realize three-dimensional heating. At the same time, the gas flows continuously in the channel and flows into the next circulation channel 22 through the flow guide pipe 23 arranged at the end of the channel to form a multi-section continuous heat circulation system. In order to achieve moderate cooling of the object after heating and avoid structural stress or deformation caused by sudden cooling, multiple circulation channels 24 are arranged in another machine body 5. The fan 2 12 sends the inhaled cold air to the circulation channels 24 through the pipe 13, and the cold air is blown to the object through the air outlets 25 to gently cool the object. The flow guide pipe 23 transfers the gas flow between the circulation channels to ensure the orderly flow of the gas. At the same time, in the circulation channels 24 near the front end area, the entering cold air is partially preheated due to the relatively high ambient temperature, so that the object will not be suddenly cooled in the initial cooling stage, avoiding affecting the coating curing effect. The whole heating and cooling process is designed by heat gradient to realize uniform heating and sufficient curing of the object, thereby improving the coating adhesion and overall performance.
