All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 5 , the present utility model provides two technical solutions, specifically including the following embodiments:

[0031] Embodiment 1:

[0032] A paint surface drying device for processing includes a drying machine body 1 and a paint surface drying mechanism 2, which is arranged in the middle of the upper part of the drying machine body 1 and is used for blowing air to accelerate the formation of the paint surface. The paint surface drying mechanism 2 includes a drying treatment chamber 201, a duct 202, a hot air blower 203, an air pump support 204, a wind guide box 205, an air flow groove 206 and a draw-out plate 207. The drying treatment chamber 201 is fixedly connected to the upper surface of the drying machine body 1. An air pump support 204 is fixedly connected to the outside of the drying treatment chamber 201. A hot air blower 203 is arranged at the upper end of the air pump support 204. The temperature of the hot air flow generated by the hot air blower 203 is around 50°C, which will not damage the paint surface. The air outlet end of the hot air blower 203 is fixedly connected to a duct 202, and the other end of the duct 202 is arranged inside the wind guide box 205. The wind guide box 205 is fixedly connected to the inner top of the drying treatment chamber 201. An air flow groove 206 is arranged at the inner top of the wind guide box 205. A draw-out plate 207 is arranged on one side of the drying treatment chamber 201. The draw-out plate 207 penetrates through the drying treatment chamber 201 and is slidably connected to the drying treatment chamber 201. An air filter cloth 208 is arranged in the middle of the draw-out plate 207.

[0033] During operation, the workpiece to be painted is placed on the surface of the front conveying steel pipe 302 of the drying machine body 1. After the workpiece surface is painted, the painted workpiece is guided into the drying treatment chamber 201 through the workpiece conduction mechanism 3. Then, the hot air blower 203 generates air flow, and the heated hot air is blown to the paint surface to be dried, thereby accelerating the formation of the paint surface. Before that, the draw-out plate 207 is first pushed into the drying treatment chamber 201. At this time, the air filter cloth 208 in the middle of the draw-out plate 207 just fits on the lower surface of the wind guide box 205. The hot air flow introduced by the hot air blower 203 is filtered by the air filter cloth 208 to prevent the air flow blowing on the workpiece paint surface from carrying dust and affecting the beauty of the paint surface. If the air filter cloth 208 has a lot of attached dust, the draw-out plate 207 can be completely pulled out and removed, cleaned and dried, and then used again.

[0034] Embodiment 2:

[0035] On the basis of Embodiment 1, the workpiece conduction mechanism 3 is arranged inside the drying machine body 1 and is used to introduce the workpiece with a sprayed paint surface into different positions. The workpiece conduction mechanism 3 includes a connecting belt 301, a conveying steel pipe 302, and a transmission gear 303. The number of conveying steel pipes 302 is set to be multiple, and both ends of the multiple conveying steel pipes 302 are respectively sleeved inside two connecting belts 301. A transmission gear 303 is arranged below the rear conveying steel pipe 302, and part of the conveying steel pipes 302 are within the teeth of the transmission gear 303. The transmission gear 303 is rotatably connected to the drying machine body 1, and a motor is arranged at the position where the transmission gear 303 is rotatably connected to the drying machine body 1. The output end of the motor is in transmission connection with the transmission gear 303. The closing mechanism 4 is symmetrically arranged on the left and right sides of the paint drying mechanism 2 and is used for automatically closing when the workpiece enters and exits. The closing mechanism 4 includes a closing box 401, a sealing door 402, and a torsion spring 403. The lower end of the closing box 401 is fixedly connected to the upper surface of the drying machine body 1. Two sealing doors 402 are arranged on the outer side of the closing box 401, and both sealing doors 402 are rotatably connected to the closing box 401. A torsion spring 403 is arranged at the rotation connection position of the sealing door 402 and the closing box 401, and the torque of the torsion spring 403 is 10 Nm. After the workpiece is sprayed with paint, the motor is driven to rotate the transmission gear 303. After the transmission gear 303 rotates, the teeth of the transmission gear 303 continuously engage with the multiple conveying steel pipes 302, causing the multiple conveying steel pipes 302 and the connecting belt 301 to rotate, so as to convey the sprayed workpiece to the area of the closing mechanism 4 and the paint drying mechanism 2. When the workpiece enters the position of the closing box 401, the sprayed workpiece pushes open the sealing door 402. After the workpiece completely enters, the sealing door 402 is reset by means of the torsion spring 403 to close, preventing the hot air discharged from the subsequent paint drying mechanism 2 from being discharged from the position of the sealing door 402 of the closing box 401. It should be noted that in order to be able to push open the sealing door 402, the sprayed workpiece is generally heavy and can be processing materials such as solid wood and steel plates.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the application shall be included in the protection scope of the present application.
