[0052] like Figure 1As shown in the figure, an embodiment of the present invention discloses a building material surface spraying machine, including a base 10, a rotating clamping device 20, a spraying device 30, and a drying device 40. The base 10 is equipped with the rotating clamping device 20, which is movably connected to the base 10 and can move along the base 10. The spraying device 30 and the drying device 40 are sequentially arranged on the base 10 along the moving direction of the rotating clamping device 20. The rotating clamping device 20 is used to clamp the building material and can drive the building material to rotate, which is more conducive to the comprehensive spraying and drying of the building material. The drying device 40 performs preliminary drying of the sprayed building material to prevent paint adhesion during subsequent movement of the building material, thus avoiding affecting the spraying effect.

[0053] Specifically, such as Figure 2 As shown, the base 10 is elongated, and the rotating clamping device 20 moves along the length of the base 10. First sliding grooves 11 are formed on both sides of the base 10, extending along its length. A first driving mechanism 13 is located within the first sliding groove 11, and a first slider 12 is mounted on the first driving mechanism 13, which can move the first slider 12 along the first sliding groove 11. The rotating clamping device 20 is connected to the first slider 12. The rotating clamping device 20 is positioned above the base 10, with its bottom sides connected to the first slider 12. When the first slider 12 moves along the first sliding groove 11, it can move the rotating clamping device 20 along the length of the base 10. The spraying device 30 and the drying device 40 are sequentially fixed above the first sliding groove 11 along the length of the base 10.

[0054] In this embodiment, the first driving mechanism 13 includes a first lead screw 131, which is disposed within a first slide groove 11, extending along the length of the first slide groove 11 and rotatably connected to it. A first slider 12 is slidably connected within the first slide groove 11. The first lead screw 131 passes through the first slider 12 and is threadedly connected to it. The bottom of the rotary clamping device 20 is fixedly connected between the two first sliders 12. Rotation of the first lead screw 131 drives the rotary clamping device 20 to move along the first slide groove 11 via the first sliders 12, transporting building materials for sequential spraying and drying, thus improving work efficiency.

[0055] A first transmission groove 14 is formed at the end of the base 10 relative to the first lead screw 131. A first rotating shaft 132 is rotatably connected inside the first transmission groove 14. One end of the first rotating shaft 132 extends into the first sliding groove 11 and is fixedly connected to the first lead screw 131. The other end is fixedly connected to a first bevel gear 133, which is disposed within the first transmission groove 14. A second bevel gear 134 meshes with the bottom of the first bevel gear 133. A second rotating shaft 135 is fixed to the second bevel gear 134 and is rotatably connected to the bottom of the first transmission groove 14. A second transmission groove 15 is formed at the bottom of the first transmission groove 14. The end of the second transmission shaft away from the second bevel gear 134 extends into the second transmission groove 15 and is rotatably connected to the bottom of the second transmission groove 15. A first worm gear 136 is fixed to the second rotating shaft 135. A third rotating shaft 137 is rotatably connected inside the second transmission groove 15. A first worm gear 138 is fixedly connected to the third rotating shaft 137. The first worm gear 136 meshes with the first worm 138. A first servo motor 139 is fixedly connected to the third rotating shaft 137 and is fixedly installed inside the base 10. In use, the first servo motor 139 drives the first worm 138 to rotate via 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 via 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 via the first rotating shaft 132, thereby moving the rotary clamping device 20 through the first slider 12.

[0056] Specifically, such as Figure 3 As shown, the rotary clamping device 20 includes a mounting base 21, a rotating seat 23 arranged opposite to each other, and a clamping device 25. The mounting base 21 is disposed between two first sliders 12 and is fixedly connected to the first sliders 12. To ensure that the paint does not leak during spraying and that the drying gas does not leak during drying, the mounting base 21 is matched with the spraying device 30 and the drying device 40. During spraying and drying, the two sides of the mounting base 21 and the spraying device 30 and the drying device 40 keep the building material in a relatively closed environment. The rotating seat 23 is disposed on the two sides of the mounting base 21 that are not connected to the first sliders 12, and the clamping device 25 is disposed on the rotating seat 23. The mounting base 21 is provided with a second drive mechanism 24, and the second drive mechanism 24 is provided with the rotating seat 23, which can drive the rotating seat 23 to rotate. The clamping device 25 includes a third drive mechanism 251, and the third drive mechanism 251 is provided with clamping blocks 252 arranged opposite to each other, which can drive the clamping blocks 252 to move closer or further apart.

[0057] In this embodiment, third transmission grooves 22 are respectively provided on both sides of the mounting base 21 that are not connected to the first slider 12. A second drive mechanism 24 is installed in the third transmission groove 22. The second drive mechanism 24 includes a fourth rotating shaft 241 and a fifth rotating shaft 242. The fourth rotating shaft 241 and the fifth rotating shaft 242 are rotatably connected to the third transmission groove 22. A second worm gear 243 is fixedly connected to one end of the fourth rotating shaft 241 and is disposed in the third transmission groove 22. A rotating seat 23 is fixed to the other end. A second worm 244 is fixed on the fifth rotating shaft 242 and is disposed in the third transmission groove 22 and meshes with the second worm gear 243. A second servo motor 245 is fixed to the end of the fifth rotating shaft 242 away from the second worm 244. In use, the second servo motor 245 rotates, which drives the second worm gear 244 to rotate via the fifth rotating shaft 242. The second worm gear 244 drives the second worm wheel 243 to rotate, which in turn drives the rotating seat 23 to rotate via the fourth rotating shaft 241, thereby driving the clamping block 252 to rotate, so as to flip the building materials and perform full spraying.

[0058] The clamping device 25 includes a mounting rod 253, which is fixed to the side of the rotating seat 23 away from the fourth rotating shaft 241. A second sliding groove 254 is formed inside the mounting rod 253, and a third drive mechanism 251 is installed within the second sliding groove 254. The third drive mechanism 251 includes a second lead screw 2511, which is a bidirectional lead screw and is rotatably connected to the second sliding groove 254. Two second sliders 255 are slidably connected within the second sliding groove 254. The upper and lower parts of the second lead screw 2511 each pass through a second slider 255 and are threadedly connected to it. A clamping block 252 is fixed to the end of the second slider 255 away from the rotating seat 23. A third servo motor 2512 is provided at the top of the second lead screw 2511, and the third servo motor 2512 is fixed inside the mounting rod 253, with its output end fixedly connected to the second lead screw 2511. In use, the third servo motor 2512 drives the second lead screw 2511 to rotate, which in turn drives the two second sliders 255 to move closer or further apart inside the second slide groove 254, thereby causing the clamping block 252 to slide accordingly, clamping the building materials so that they can be sprayed, thus improving the practicality of the spraying machine.

[0059] Specifically, such as Figure 4 and Figure 5As shown, the spraying device 30 includes a spraying box 31, with a liquid storage tank 32 connected to the top of the spraying box 31. The liquid storage tank 32 is used to supply paint to the spraying box 31. A spraying pipe 311 is provided inside the spraying box 31, and a telescopic pipe 33 is provided on the spraying pipe 311. The telescopic pipe 33 is connected to the liquid storage tank 32. A fourth drive mechanism 312 is connected to the spraying pipe 311, which can drive the spraying pipe 311 to move horizontally. A stirring rod 321 is provided inside the liquid storage tank 32 for stirring the paint inside the liquid storage tank 32.

[0060] In this embodiment, as Figure 4 As shown, the fourth drive mechanism 312 is disposed within the third slide groove 313, which is located within the spray box 31. The fourth drive mechanism 312 includes a third lead screw 3121, which is configured as a reciprocating lead screw and is rotatably connected to the third slide groove 313. A third slider 314 is slidably connected within the third slide groove 313. The third lead screw 3121 passes through the third slider 314 and is threadedly connected to it. A fourth servo motor 3122 is fixedly installed inside the spray box 31, and its output end is fixedly connected to the third lead screw 3121. A fourth slide groove 315 is located on one side of the third slide groove 313 inside the spray box 31. A fourth slider 316 is slidably connected within the fourth slide groove 315, and one side of the fourth slider 316 is fixedly connected to the third slider 314. A spray pipe 311 is fixedly connected inside the fourth slider 316. A telescopic tube 33 is fixedly connected to the top of the spray pipe 311. The telescopic tube 33 is connected to the upper liquid storage tank 32. In use, the fourth servo motor 3122 drives the third lead screw 3121 to rotate, which in turn drives the third slider 314 to slide back and forth inside the third slide groove 313. This, in turn, drives the fourth slider 316 and the spray tube 311 to slide back and forth, thus facilitating the comprehensive spraying of building materials, ensuring the spraying effect, and improving the practicality of the spraying machine.

[0061] like Figure 5 As shown, a stirring rod 321 is rotatably connected inside the storage tank 32, and a fifth servo motor 322 is fixed to one end of the stirring rod 321. The fifth servo motor 322 is installed inside the storage tank 32, and its output end is fixedly connected to the stirring rod 321. One end of the telescopic tube 33 extends into the interior of the storage tank 32, and a pressure pump 34 is connected to the telescopic tube 33. The pressure pump 34 is located on the outside of the storage tank 32. A feed hopper 35 is fixedly connected to the storage tank 32. In use, the fifth servo motor 322 drives the stirring rod 321 to rotate, stirring the paint inside the storage tank 32. The pressure pump 34 pressurizes the paint and then sends it through the telescopic tube 33 into the spray booth 31. The use of the stirring rod 321 for stirring prevents paint sedimentation and ensures spray quality.

[0062] Specifically, such as Figure 6 and Figure 7As shown, the drying device 40 includes a heating chamber 41 and a drying wall 42 arranged opposite to it. The heating chamber 41 has an air inlet 411 on its side and contains a fan 412 and a heating pipe 413. The drying wall 42, arranged opposite to it, is located at the bottom of the heating chamber 41 and is mounted on the upper part of the sliding groove 10. The drying wall 42 has an air outlet 421 and an air outlet pipe 422 inside it, which communicates with the heating chamber 41.

[0063] In this embodiment, the drying device 40 has two heating chambers 41 at its top, and a connecting part 43 between the two heating chambers 41. Each heating chamber 41 corresponds to a drying wall 42 on one side, and heated gas is introduced into the corresponding drying wall 42. Multiple heating tubes 413 are installed in each heating chamber 41 to heat the gas inside. An air inlet 411 is provided on one side of each heating chamber 41, and a fan 412 is fixed inside the heating chamber 41 near the air inlet 411. An air outlet 422 is fixed on the side of the heating chamber 41 away from the air inlet 411, and the air outlet 422 leads into the corresponding drying wall 42. Multiple air outlets 421 are provided on the inner side of the drying wall 42. Multiple ventilation holes 431 are provided on the connecting part 43. Preferably, a temperature sensor (not shown in the figure) is installed on the inner side of the drying wall 42. The temperature sensor monitors the temperature of the drying gas, facilitating temperature control by workers and improving the drying quality of building materials. In use, the two sides of the mounting base 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. The outside air enters the heating chamber 41 through the air inlet 411. After the heating pipe 413 heats the air in the heating chamber 41, it enters the corresponding drying wall 42 through the air outlet 422 and flows towards the building materials from the air outlet 421. After drying the building materials, the gas flows out from the ventilation hole 431 at the top.

[0064] A method using a building material surface spraying machine as described above includes the following steps:

[0065] S1: The staff first injects the paint into the storage tank 32 through the feed hopper 35, and starts the fifth servo motor 322 to drive the stirring roller to rotate, stirring the paint inside the storage tank 32 to prevent the paint inside the storage tank 32 from settling.

[0066] S2: The staff places the building materials between the two sets of clamping blocks 252, starts the third servo motor 2512 to drive the second lead screw 2511 to rotate, and the two sets of second sliders 255 slide close to each other inside the second slide groove 254, thereby driving the two sets of clamping blocks 252 to move closer to each other and clamp the building materials.

[0067] S3: Start the first servo motor 139. The first servo motor 139 drives the first worm gear 138 to rotate through the third rotating shaft 137. The first worm gear 138 drives the first worm wheel 136 to rotate. The first worm wheel 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 into the interior of the spray box 31.

[0068] S4: Start the pressurization pump 34 to transport the paint inside the storage tank 32 through the telescopic pipe 33 to the inside of the spray pipe 311, and spray the paint onto the surface of the building material through the spray pipe 311. Start the fourth servo motor 3122, which drives the third lead screw 3121 to rotate, causing the third slider 314 to slide back and forth inside the third slide groove 313, thereby causing the fourth slider 316 and the spray pipe 311 to slide back and forth, thus spraying the entire surface of the building material.

[0069] S5: After one side of the building material is sprayed, the second servo motor 245 is started. The rotation of the second servo motor 245 drives the second worm gear 244 to rotate through the fifth rotating shaft 242. The second worm gear 244 drives the second worm wheel 243 to rotate. The second worm wheel 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 flip the building material and spray it all over.

[0070] S6: After the building materials are sprayed, the first drive mechanism 13 is activated to move the rotating clamping device 20 and the building materials into the drying device 40. The two sides of the mounting base 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. External air enters the heating chamber 41 through the air inlet 411. After the heating pipe 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 towards the building materials from the air outlet 421. After the building materials are initially dried, the gas flows out from the ventilation hole 431 at the top. By fixing a temperature sensor inside 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, thereby improving the drying quality of the building materials.

[0071] The advantages and positive effects of this utility model are:

[0072] 1. By setting up a rotating clamping device to clamp and flip the building materials, the surface of the building materials is fully sprayed, ensuring the spraying effect.

[0073] 2. By installing a liquid storage tank, paint sedimentation is avoided, ensuring spraying quality. The movable spray pipe further facilitates comprehensive spraying of building materials.

[0074] 3. By setting up a drying device, the building materials are pre-dried to avoid paint sticking when the building materials are moved later, which would affect the spraying effect.

[0075] 4. By setting up a first driving mechanism to move the rotating clamping device, the building materials are transported and sprayed and dried in sequence, which improves work efficiency.

[0076] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
