[0024] Figure 1 , Figure 2 and Figure 3 The powder spraying chamber shown includes a main chamber 1, an electrically controlled conveyor belt 2 installed on the upper part of the main chamber 1, and an electrically controlled centrifugal fan 3 installed on the outer side of the main chamber 1. The upper part of the main chamber 1 has a top-mounted feeding port that cooperates with the electrically controlled conveyor belt 2. The inner wall of the right side of the main chamber 1 has a side-mounted air outlet. The bottom surface of the inner bottom of the main chamber 1 has a bottom-mounted return port. The electrically controlled conveyor belt 2 is equipped with a bottom mounting base 4. The bottom of the bottom mounting base 4 is equipped with an electrically controlled lifting conveyor. The top-mounted feeding port is equipped with a flip-type top-mounted closed cover that cooperates with the electrically controlled lifting conveyor. The side-mounted air outlet is equipped with an electrically controlled flip-type guide hood for installing the electrically controlled centrifugal fan 3. The bottom-mounted return port is equipped with an electrically controlled lifting collection box.

[0025] Both the electrically controlled conveyor belt 2 and the electrically controlled centrifugal fan 3 are existing technologies. The electrically controlled conveyor belt 2 is used to control the bottom mounting base 4 to move and transport horizontally on the main compartment 1, while the electrically controlled centrifugal fan 3 controls the intake of external air and then blows it into the main compartment 1.

[0026] To facilitate top hoisting, the electrically controlled lifting and conveying equipment includes an electric winch 5 fixedly installed inside the bottom mounting base 4 and external lifting rings 6 installed at one end of the winch rope at both ends of the electric winch 5.

[0027] To facilitate top-mounted electric adjustment, the flip-type top-mounted closing cover includes an arc-shaped flip-type closing plate 7 movably mounted on both sides of the top-mounted feeding port, a top-mounted mounting bracket 8 fixed on both sides of the upper opening of the top-mounted feeding port, and a top-mounted electric control support rod 9 movably mounted between the arc-shaped flip-type closing plate 7 and the top-mounted mounting bracket 8.

[0028] The top-mounted electrically controlled support rod 9 is existing technology, which is adjusted by driving the arc-shaped flip-closing plate 7 to flip.

[0029] To accommodate lateral angle adjustment, the electrically controlled tilting air guide includes a tilting cover 10 movably mounted on the inner top surface of the side air outlet, an outer mounting bracket 11 fixed to one side of the outer opening of the side air outlet, a side-mounted electrically controlled support rod 12 movably mounted between the tilting cover 10 and the outer mounting bracket 11, and an elastic closing plate 13 mounted at the inner opening position of the side air outlet.

[0030] The side-mounted electrically controlled support rod 12 is existing technology, which controls the flipping cover 10 to flip inward by extending it.

[0031] To facilitate electric lifting, the electrically controlled lifting collection box includes a lifting collection box 14 inserted into the bottom return port, a bottom assembly frame 15 fixed to the periphery of the lower opening of the bottom return port, and an electrically controlled lifting machine 16 installed on the bottom surface of the bottom assembly frame 15 and the lower end of the lifting collection box 14.

[0032] The electrically controlled lifting platform 16 is existing technology and is used to control the lifting of the material collection box 14.

[0033] To improve the top sealing, an arc-shaped transition port 17 is provided on the side wall of the arc-shaped flip-up closing plate 7 to cooperate with the winding ropes at both ends of the electric winch 5.

[0034] The curved transition port 17 is internally fitted with a brush or flexible material to improve lateral sealing.

[0035] To facilitate infrared positioning, an infrared positioning module 18 is fixedly mounted on the outer wall of the top mounting bracket 8, and a positioning reflective lens 19 that cooperates with the infrared positioning module 18 is installed on the side wall of the bottom mounting base 4.

[0036] The infrared positioning module 18 emits infrared rays outward, which are then reflected and received by the positioning reflector lens 19 for positioning. This controls the closing of the electrically controlled conveyor belt 2, the release of ropes to both sides by the electric winch 5, and the descent of the external lifting ring 6 holding the workpiece. The top-mounted electrically controlled support rod 9 extends to control the arc-shaped flip-closing plate 7 to flip downward, opening the top-mounted feeding port and feeding the material into the main compartment 1. Then, the top-mounted electrically controlled support rod 9 retracts to control the arc-shaped flip-closing plate 7 to flip upward and reset, closing the top-mounted feeding port.

[0037] To facilitate material return from both sides, the lifting collection box 14 has side-mounted return ports 20 on both side walls.

[0038] A central partition is fixed inside the lifting collection box 14 between the side return ports on both sides to prevent the powder inside from being blown out by external airflow.

[0039] To facilitate the side powder spraying operation, side-mounted powder spraying nozzles 21 are fixedly installed on both sides of the inner side of the main compartment 1.

[0040] The side-mounted powder nozzle 21 uses an external feeding pipe to supply raw materials.

[0041] The powder spraying chamber of this invention, featuring a concealed powder feeding mechanism, is a closed, unmanned facility that eliminates the need for frequent personnel entry. It automatically completes feeding, powder spraying, discharging, and recycling operations, significantly improving safety and efficiency. The electrically controlled structure design makes deployment and retraction very convenient. The circulating air duct design creates an airflow around the workpiece within the main chamber 1, resulting in a wider spraying area and greatly improved powder uniformity. An electrically controlled rotating guide hood with an internally installed electrically controlled centrifugal fan 3 controls the airflow angle, allowing for more diverse airflow directions. An electrically controlled lifting collection box inside the bottom-mounted return port facilitates waste recycling and dust collection.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
