The second lifting mechanism comprises an electric lifting component 31 and a second connecting block 32 connected with the electric lifting component 31, and a second electromagnet 33 is installed on the second connecting block 32. Specifically, the electric lifting assembly 31 includes an electric push rod 312 and a push rod motor 311 for providing power to the electric push rod 312, and the second connecting block 32 is fixedly connected to the electric push rod 312. The spray head 70 is provided with a housing which can be adsorbed by the electromagnet, and the spray head 70 is adsorbed and mounted on the first connecting block 233 or the second connecting block 32. The first motor 21 drives the synchronous pulley 222 to rotate, and drives the lead screw 231 to rotate through the transmission action of the synchronous belt 221, so that the first connecting block 233 moves along the lead screw 231, and the spray head 70 is driven to move up and down when being adsorbed on the first connecting block 233.
The moving mechanism 40 includes a roller 41, a roller 42 connected to the roller 41, a second transmission assembly 43 and a second motor 44, the second transmission assembly 43 includes a timing belt 431 and a pair of timing pulleys 432, one of the timing pulleys 432 is in transmission connection with an output shaft of the second motor 44, and the other timing pulley 432 is sleeved on the roller 42. The second motor 44 drives the synchronous pulley 432 to rotate, and the roller 42 is driven to rotate by the transmission of the synchronous belt 431, so that the roller 41 rotates, and the carrying platform 10 horizontally moves.
The carrying platform 10 comprises a bottom support 11, a top support 12 and a vertical support 13 arranged between the bottom support 11 and the top support 12, the vertical support 13 comprises a stand column 131 and a pair of limiting columns 132, a cross support 14 is arranged between the stand column 131 and the limiting columns 132, and the spray head 70 is positioned between the two limiting columns 132. The bottom brace 11, the top brace 12, the cross brace 14 and the vertical brace 13 are all made of industrial aluminum profiles to ensure the rigidity and stability of the entire carrying platform 10. The first lifting mechanism 20 further comprises a fixing plate 25, the fixing plate 25 is fixedly connected with the cross brace 14, the lead screw 231 and the guide post 232 are installed between the bottom brace 11 and the fixing plate 25, and the first motor 21 is fixedly installed on the fixing plate 25.
The working principle is as follows: the first electromagnet 24 is electrified, the spray head 70 is adsorbed with the first electromagnet 24 of the first connecting block 233, the material conveying pump 60 is electrified, and the spray head 70 starts spraying. The first motor 21 is powered on, and drives the screw rod 231 to rotate through the synchronous belt transmission, so that the first connecting block 233 moves upwards along the screw rod 231. When the first connecting block 233 moves to the top of the lead screw 231, the first motor 21 stops rotating, the first electromagnet 24 is powered off, and the adsorption force of the first electromagnet 24 to the spray head 70 disappears. The second electromagnet 33 is electrified to generate an adsorption force, the spray head 70 is attracted by the second electromagnet 33 and connected with the second connecting block 32, and the electric lifting component 31 starts to work to push the second connecting block 32 to move upwards. In the above process, the spray head 70 completes the spraying in the ascending process.
When the spray head 70 moves to a designated height (i.e. the height of the wall surface to be coated), the second motor 44 starts to work, and the carrying platform 10 advances a distance through the synchronous belt drive. The electric push rod 312 then retracts to move the second connecting block 32 (while the spray head 70 is still attached to the second connecting block 32) downward. When the head 70 returns to the top of the lead screw 231, the second electromagnet 33 is turned off, the attraction force of the second electromagnet 33 to the head 70 disappears, the first electromagnet 24 is energized, and the head 70 is attracted to the first electromagnet 24 and connected to the first connection block 233. At this time, the first motor 21 is rotated in the reverse direction, so that the first connecting block 233 moves down along the lead screw 231 until the bottom end of the lead screw 231. During which the spray head 70 completes the spraying during the lowering.
