The detachable connection mode of the electric heating element makes it convenient for the staff to remove the electric heating element from the conical cover 2 for replacement, which is convenient and practical.

[0022] A movable bracket 1 is provided on the back of the conical cover 2, and both ends of the movable bracket 1 are rotatably connected to the conical cover 2. A rotating mechanism for adjusting the angle of the conical cover 2 is provided between the movable bracket 1 and the conical cover 2; by controlling the rotation of the conical cover 2 through the rotating mechanism, the painting and drying angles of the paint spraying and drying device can be changed.

[0023] A spray pipe is provided in front of the electric heating element, and both ends of the spray pipe are inserted into the expansion groove 8 provided on the front of the conical cover 2. The expansion groove 8 is provided on both sides of the conical cover 2, and bolt positioning parts for fixing the spray pipe are provided in the expansion groove 8. The spray pipe is used to spray paint on the surface of the carriage. When the spray pipe is removed from the conical cover 2, the bolt positioning parts can be released to lock the two ends of the spray pipe. It is convenient for disassembly and replacement, and easy for the staff to maintain.

[0024] Regarding the electric heating element: the electric heating element includes an assembly frame 6 arranged inside the conical cover 2, a plurality of electric heating rods 7 are arranged inside the assembly frame 6, thread grooves are provided on both sides of the assembly frame 6, and the thread grooves are threadedly connected with the fixing bolts 18 assembled on both sides of the conical cover 2. When removing the assembly frame 6 from the conical cover 2, the fixing bolts 18 on both sides of the conical cover 2 can be unscrewed from the thread grooves on both sides of the assembly frame 6.

[0025] The rotating mechanism is installed between the movable bracket 1 and the conical cover 2, and is used to push the conical cover 2 to rotate with the point where it is connected to the movable bracket 1 as the central axis. Specifically, the rotating mechanism includes a U-shaped fixed frame 9 and a U-shaped movable frame 10. The U-shaped fixed frame 9 is fixedly connected to the upper end of the movable bracket 1. The two ends of the U-shaped movable frame 10 are rotatably connected to the first hinge seat 11 provided at the upper end of the movable bracket 1.

The output end of the electric push rod 12 is rotatably connected to the second hinge seat 13 provided at the upper end of the U-shaped movable frame 10 through a rotating pin. The angle adjustment of the conical cover 2 is controlled by the electric push rod 12. When the electric push rod 12 pushes the conical cover 2 through the U-shaped movable frame 10, the conical cover 2 will deflect toward the bottom thereof. When the electric push rod 12 pulls the conical cover 2 through the U-shaped movable frame 10, the conical cover 2 will deflect toward the top thereof.

[0026] More specifically, a back plate 14 is provided on the back of the U-shaped fixing frame 9, and a plurality of threaded holes are provided on the back of the back plate 14 and the back of the movable bracket 1.

The pressure pump transports the paint into the nozzle 3 through the conduit 4, and then it is sprayed out by the nozzle 5 on the nozzle 3. After the spraying is completed, the hot air flow will surge from the rear of the nozzle 3 to dry the surface of the carriage.

[0028] When assembling the spray pipe fittings, the slots 15 at both ends of the nozzle 3 are inserted into the slots 15 through the flaring grooves 8. The slots 15 will limit the position of the nozzle 3 by cooperating with the positioning sleeve 16. Finally, the bolt positioning member further locks the slots 15. Specifically, the bolt positioning member includes two brackets 22, which are fixedly connected to both sides of the cone cover 2. The slot 15 is sleeved on the lower half of the positioning sleeve 16. The slot 15 is equipped with a positioning bolt 21 on the outside. The positioning bolt 21 passes through the bracket 22 and is threadedly connected to the positioning hole 19 opened on the outside of the positioning sleeve 16. The positioning bolt 21 is also threadedly connected to the bracket 22. When the bolt positioning member releases the fixing of the positioning sleeve 16, it only needs to unscrew the positioning bolt 21 from the positioning hole 19 on the positioning sleeve 16.

[0029] Working principle: The airflow blown out by the conical cover 2 will form hot air when passing through the electric heating element, which will dry the paint sprayed on the surface of the car body. The rotation of the conical cover 2 is controlled by the rotating mechanism, so the spraying and drying angles of the paint spraying and drying device can be changed. When removing the spray pipe from the conical cover 2, the bolt positioning parts can be released to lock the two ends of the spray pipe. It is convenient to disassemble and replace, and easy for the staff to maintain.
