DETAILED DESCRIPTION

[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, the embodiment of the utility model provides a device for baking and drying parts after spraying paint, including a rotating mechanism 101, wherein the rotating mechanism 101 includes a bottom plate 21, a motor 14 and a rotating shaft 8;

[0028] The output shaft of the motor 14 is mounted on the bottom end of the rotating shaft 8, the outer side wall of the rotating shaft 8 is rotatably connected to the bottom plate 21 through a bearing, the upper surface of the bottom plate 21 is fixedly connected to the second housing 7, the inner side wall of the second housing 7 is installed with a suction fan 2, the air outlet of the suction fan 2 is connected with a connecting pipe 22, the upper surface of the bottom plate 21 is fixedly connected to the first housing 1, the end of the connecting pipe 22 away from the suction fan 2 is connected to the inside of the first housing 1, the upper surface of the bottom plate 21 is fixedly connected to the shell 19, and the inner side wall of the shell 19 is evenly installed with heating pipes 3;

[0029] A purification mechanism 102 is installed inside the first housing 1 .

[0030] In one embodiment, the outer wall of the rotating shaft 8 is evenly fixedly connected with a screen 10, and the screen 10 is connected to realize the self-rotation of the screen 10. The shell 19 is located in front of the suction fan 2. The shell 19 is lower than the second shell 7. When the gas rises, the gas flows into the suction fan 2.

[0031] In one embodiment, the purification mechanism 102 includes a filter plate 5, a nano-silver filter 11, a dust collecting rack 12, an activated carbon filter 23 and a HEPA filter 9. The inner wall of the first shell 1 is screwed with the filter plate 5, the nano-silver filter 11, the dust collecting rack 12, the activated carbon filter 23 and the HEPA filter 9 in sequence from top to bottom. An exhaust port 13 is installed at the bottom of the first shell 1. Harmful gases pass through the rack and the filter to adsorb toxic components in the harmful gases. A control switch 16 is installed on the outside of the second shell 7. The control switch 16 is electrically connected to the motor 14, the suction fan 2 and the heating tube 3 respectively. A door body 17 is installed on one side of the second shell 7 for easy use.

[0032] When the utility model is working: first, the door body 17 is opened, and the parts that have been painted are placed on the screen 10, and the door body 17 is closed. Through the control of the control switch 16, the motor 14 starts to work, and the rotating shaft 8 rotates accordingly, thereby driving the screen 10 to rotate at a constant speed. While the screen 10 rotates, the switch controlling the heating tube 3 is turned on, so that the heating tube 3 starts to operate to generate heat for baking the paint on the surface of the parts;

[0033] Next, when the heating tube 3 is working, the paint spraying on the surface of the parts generates a large amount of harmful gas. The suction fan 2 is started by the control of the control switch 16. Since the housing 19 is lower than the second housing 7, the gas flows into the suction fan 2, and the suction fan 2 starts to operate, sucking the harmful gas into the connecting pipe 22.

[0034] Finally, the gas flows into the first shell 1 through the connecting pipe 22, the gas cools in the first shell 1 and starts to sink, first flows into the filter plate 5, further filters the larger particles in the air, sinks into the nano silver filter 11, filters out the silver ions in the gas, then goes to the dust collecting rack 12, further filters the smaller dust and dust particles in the gas, and sinks into the activated carbon filter 23 again, and the harmful components in the gas are absorbed by the activated carbon, and finally, the gas flows into the HEPA filter 9, and the particles are filtered again. After the above steps, the harmful gas that flows out is filtered into gas that is harmless to the human body, and then flows out of the machine through the exhaust port 13.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
