A first limit plate 208 is welded to the inner lower surface of the box body 201, and a second limit plate 209 is welded to the outer lower surface of the box body 201. Through the arrangement of the box body 201, the cylinder 202, the push rod 203, the push plate 204, the motor 205, the rotating shaft 206, the clamping shaft 207, the first limit plate 208 and the second limit plate 209, when the equipment body 1 needs to be put into use, it is turned on. The power supply then manually places the valve stem to be processed in the box body 201, and the valve stem in the inclined area of ​​the box body 201 enters the groove of the clamping shaft 207 under the action of gravity. When the valve stem in the inclined area is transported by the clamping shaft 207, it is considered that some valve stems are still in the horizontal area of ​​the box body 201. At this time, the cylinder 202 pushes the push rod 203, and the push rod 203 pushes the push plate 204. The push plate 204 pushes the valve stem in the horizontal area of ​​the box body 201 to the feeding port of the clamping shaft 207 and enters the groove of the clamping shaft 207, clamping the material. The shaft 207 rotates driven by the motor 205, and the valve stem that has just entered and is at the top of it also rotates.

[0022] Furthermore, the drying mechanism 3 includes a drying chamber 301, a support rod 302, a cooling gun 303, a fixing sleeve 304, a supporting sleeve 305 and an electric heating pipe 306. The drying chamber 301 is installed on one side surface of the equipment body 1, the supporting rod 302 is installed on the inner wall of the drying chamber 301, the cooling gun 303 is tightly attached to one end surface of the supporting rod 302, the fixing sleeve 304 is installed on the inner wall of the drying chamber 301, and the supporting sleeve 305 is fixedly connected to one side surface of the fixing sleeve 304. An electric heating tube 306 is connected to the surface of one side of 305. Through the arrangement of the drying chamber 301, the support rod 302, the cooling gun 303, the fixing sleeve 304, the support sleeve 305 and the electric heating tube 306, when the valve stem completes the surface coating, the electric heating tube 306 is first in a working state when the power is turned on, and the electric heating tube 306 bakes the transmitted valve stem so that the surface coating is in a stable state. After the baking is completed, the cooling gun 303 cools the valve stem to reduce its surface temperature.

[0023] Furthermore, the inner wall size of the motor 205 matches the outer wall size of the rotating shaft 206, and the outer wall size of the rotating shaft 206 matches the inner wall size of the clamping shaft 207. Through the setting of the motor 205, the clamping shaft 207 can be rotated, so that the valve stem entering the groove of the clamping shaft 207 can be rotated to achieve delivery.

[0024] Furthermore, the push rod 203 and the cylinder 202 form a telescopic structure, and the inner wall size of the push rod 203 matches the outer wall size of the cylinder 202. Through the setting of the cylinder 202, the position of the push plate 204 can be adjusted, so that the valve stem in the horizontal area of ​​the box body 201 can be pushed.

[0025] Furthermore, the outer wall size of the rotating shaft 206 is consistent with the inner wall size of the box body 201. The rotating shaft 206 penetrates and is rotatably connected to the inner surface of the box body 201. Through the setting of the rotating shaft 206, the clamping shaft 207 can be driven to rotate, so that the valve stem entering the groove of the clamping shaft 207 can be rotated to achieve delivery.

[0026] Furthermore, the outer wall size of the electric heating tube 306 is consistent with the inner wall size of the support sleeve 305, and the electric heating tube 306 is distributed at equal intervals on the inner surface of the drying chamber 301. Through the setting of the electric heating tube 306, after the valve stem completes the surface coating, it is heated, so that its surface is quickly in a stable state.

[0027] Furthermore, the inner wall size of the cooling gun 303 is consistent with the outer wall size of the support rod 302, and the cooling gun 303 is symmetrically distributed on the inner surface of the drying chamber 301 with the central axis. Through the setting of the cooling gun 303, after the valve stem completes surface baking, it is cooled, so that it can quickly enter the next process.

[0028] Working principle: First, when the equipment body 1 needs to be put into use, the power is turned on and the valve stem to be processed is manually placed in the box body 201. The valve stem in the inclined area of ​​the box body 201 enters the groove of the clamping shaft 207 under the action of gravity. When the valve stem in the inclined area is transported by the clamping shaft 207, it is considered that some valve stems are still in the horizontal area of ​​the box body 201. At this time, the cylinder 202 pushes the push rod 203, and the push rod 203 pushes the push plate 204. The push plate 204 pushes the valve stem in the horizontal area of ​​the box body 201 to the feeding port of the clamping shaft 207 and enters the groove of the clamping shaft 207. The clamping shaft 207 rotates under the drive of the motor 205, and the valve stem that has just entered and is at the top of it also rotates. When the valve stem rotates to the At a limit plate 208, it will fall downward under the action of gravity. Under the action of the first limit plate 208 and the second limit plate 209, the valve stem will fall into the cylindrical fixture rotating on the assembly line. The valve stem rotates under the action of the cylindrical fixture, and the automatic nozzle performs surface coating on it, which solves the problems of uneven surface coating, low production efficiency and high production cost caused by manual operation of metal coating in existing valve stem anti-rust equipment. When the valve stem completes the surface coating, the electric heating tube 306 is in a working state when the power is turned on. The electric heating tube 306 bakes the transmitted valve stem so that the surface coating is in a stable state. After the baking is completed, the cooling gun 303 cools the valve stem to reduce its surface temperature so that it can quickly enter the next process.
