[0064] Specifically, Figure 4 and Figure 5 As shown, the spraying device 30 includes a spraying box 31, and a liquid storage tank 32 is connected to the top of the spraying box 31.

When in use, the fourth servo motor 3122 drives the third lead screw 3121 to rotate, drives the third slider 314 to slide back and forth inside the third slide groove 313, thereby driving the fourth slider 316 and the spraying tube 311 to slide back and forth, so as to facilitate comprehensive spraying of building materials, ensure the spraying effect, and improve the practicality of the sprayer.

[0066] like Figure 5 As shown, a stirring rod 321 is rotatably connected inside the liquid storage tank 32, and a fifth servo motor 322 is fixed to one end of the stirring rod 321.

[0067] Specifically, Figure 6 and Figure 7 As shown, the drying device 40 includes a heating chamber 41 and a drying wall 42 arranged opposite to each other. An air inlet 411 is provided on the side of the heating chamber 41, and a fan 412 and a heating pipe 413 are arranged inside.

When in use, both sides of the mounting base 21 are adapted to the drying device 40, so that the building materials are placed in a relatively closed environment. The fan 412 rotates to make the air in the heating chamber 41 flow, and the external air enters the heating chamber 41 from the air inlet 411. After the heating pipe 413 heats the air in the heating chamber 41, the air enters the corresponding drying wall 42 through the air outlet pipe 422, and flows from the air outlet 421 toward the building materials. After drying the building materials, the gas flows out from the ventilation hole 431 at the top.

[0069] A method of using the building material surface spraying machine as described above comprises the following steps:

[0070] S1: The staff first injects the paint into the liquid storage tank 32 through the feed hopper 35, starts the fifth servo motor 322 to drive the stirring roller to rotate, and stirs the paint inside the liquid storage tank 32 to prevent the paint inside the liquid storage tank 32 from settling;

[0071] S2: The staff places the building materials between the two groups of clamping blocks 252, starts the third servo motor 2512 to drive the second lead screw 2511 to rotate, and the two groups of second sliders 255 slide close to each other inside the second slide groove 254, thereby driving the two groups of clamping blocks 252 to move close to each other to clamp the building materials;

[0072] S3: Start the first servo motor 139, the first servo motor 139 drives the first worm 138 to rotate through the third rotating shaft 137, the first worm 138 drives the first worm gear 136 to rotate, the first worm gear 136 drives the second bevel gear 134 to rotate through the second rotating shaft 135, the second bevel gear 134 drives the first bevel gear 133 to rotate, the first bevel gear 133 drives the first lead screw 131 to rotate through the first rotating shaft 132, the first lead screw 131 drives the first slider 12 to slide in the first slide groove 11, thereby driving the rotary clamping device 20 to move to the inside of the spray box 31;

[0073] S4: Start the pressure pump 34 to transport the paint in the liquid storage tank 32 to the inside of the spraying tube 311 through the telescopic tube 33, and spray the paint onto the surface of the building material through the spraying tube 311. Start the fourth servo motor 3122, the fourth servo motor 3122 drives the third lead screw 3121 to rotate, drives the third slider 314 to slide back and forth inside the third slide groove 313, thereby driving the fourth slider 316 and the spraying tube 311 to slide back and forth, so as to fully spray the surface of the building material;

[0074] S5: After one side of the building material is sprayed, the second servo motor 245 is started, the second servo motor 245 rotates through the fifth rotating shaft 242 to drive the second worm 244 to rotate, the second worm 244 drives the second worm gear 243 to rotate, the second worm gear 243 drives the rotating seat 23 to rotate through the fourth rotating shaft 241, thereby driving the clamping block 252 to rotate, so as to turn the building material over and perform full spraying;

[0075] S6: After the spraying of the building materials is completed, the first driving mechanism 13 is started, and the rotating clamping device 20 and the building materials are moved to the interior of the drying device 40. The two sides of the mounting seat 21 are adapted to the drying device 40, so that the building materials are in a relatively closed environment. The fan 412 rotates to make the air in the heating chamber 41 flow, and the external air enters the heating chamber 41 from the air inlet 411. After the heating tube 413 heats the air in the heating chamber 41, it enters the corresponding drying wall 42 through the air outlet 422. The heated gas flows from the air outlet 421 toward the building materials. After the building materials are preliminarily dried, the gas flows out from the ventilation holes 431 on the top. By fixing a temperature sensor on the inner side of the drying wall 42 to monitor the temperature of the drying gas, it is convenient for the staff to control and adjust the drying temperature and improve the drying quality of the building materials.
