By setting the two heating wires 4 to be connected to the external circuit, the interior of the drying chamber 1 is heated, so that the temperature inside the drying chamber 1 rises to the required drying temperature, thereby drying the painted parts placed inside the drying chamber 1.

[0032] In this embodiment, a plurality of air inlets 101 distributed left and right are provided on the inner walls on both sides of the drying chamber 1, and the plurality of air inlets 101 are distributed in an equidistant linear array, and the plurality of air inlets 101 are located on one side of the heating wire 4, and a blower 5 is fixedly connected to the outer walls on both sides of the drying chamber 1 and at the openings of the plurality of air inlets 101, and the input ends of the plurality of blowers 5 are electrically connected to the output ends of the external power supply, and the air inlet ends of the plurality of blowers 5 are fixedly provided with dust filter screens, and by setting the plurality of blowers 5 to operate under the input of external power, the heat radiated from the two heating wires 4 is directed to the drying chamber 1.

The plurality of pressure relief valves 7 are located between the two motor protection frames 3, and the interiors of the plurality of pressure relief valves 7 are connected with the interior of the drying chamber 1. By providing a plurality of pressure relief valves 7, the air pressure inside the drying chamber 1 is regulated, so that the internal air pressure of the drying chamber 1 is always kept consistent with the external air pressure.

[0035] Working principle: when in use, firstly, two blowers 5 are powered on, so that the two blowers 5 radiate heat to the inside of the drying chamber 1, thereby preheating the inside of the drying chamber 1, so that the internal temperature of the drying chamber 1 rises. When the inside of the drying chamber 1 reaches the required temperature for drying, multiple blowers 5 are started, and the multiple blowers 5 blow the heat radiated by the two heating wires 4 to the middle;

[0036] Then, the power supply of the two AC motors 301 is turned on, so that the two AC motors 301 operate under the action of external power and drive the two active bevel gears 302 to rotate, so that the two passive bevel gears 303 meshing with the two active bevel gears 302 rotate, further driving the two power input shafts 304 fixedly connected to the two passive bevel gears 303 to rotate synchronously, and driving the two two active gears 305 fixedly connected to the power input shafts 304 to rotate, so that the four passive gears 306 meshing with the active gears 305 rotate synchronously, further causing the four power output shafts 2 to rotate, and driving the four The shaped wheels 201 rotate synchronously, thereby driving the conveyor chain 202 to operate, so that the multiple bending rods 203 and the hook 205 rotate synchronously. When the hook 205 rotates with the conveyor chain 202, it is affected by the core of the rotating sleeve 204 and the rack 207, so that the hook 205 rotates along the rotation direction of the rotating sleeve 204 and the bending rod 203. Then, after the two closed doors 6 are opened, the painted parts to be dried are hung on the hook 205, and the hook 205 moves synchronously, driving the painted parts to rotate and rotate with the conveyor chain 202 inside the drying chamber 1, and receive the heat radiated from the heating wires 4 on both sides, so that the surface of the painted parts is heated evenly;

[0037] After the painted parts are dried, the power supply of the two heating wires 4 is cut off, and the two heating wires 4 stop supplying heat. At this time, the conveyor chain 202 continues to rotate under the power support of the AC motor 301 and drives the hook 205 and the painted parts suspended by the hook 205 to rotate and rotate. During this period, multiple blowers 5 continue to operate to transport external normal temperature air to the interior of the drying chamber 1, thereby air cooling the painted parts, so that the dried painted parts inside the drying chamber 1 can be quickly cooled. When the painted parts are cooled to room temperature, the power supply of the multiple blowers 5 is cut off and the two closed doors 6 are immediately opened, and then the suspended painted parts on the multiple hooks 205 are removed in turn. The paint drying device ensures the rotation drying of the painted parts and the uniformity of the drying of the painted parts. At the same time, multiple painted parts can be dried, which directly improves the drying efficiency. After the drying is completed, the painted parts can be quickly cooled, which improves the operating efficiency and practicality of the device.
