[0015] The inside of the spray printing box body 1 is provided with a spraying pump M114, a suction cup vacuum pump M215, an internal battery 16, a spraying control board 17 and a suction cup control board 18, the spraying pump M114 and the suction cup vacuum pump M215 are arranged at the two side ends of the inside of the spray printing box body 1 respectively, the internal battery 16 is arranged at the middle section of the inside of the spray printing box body 1, the spraying control board 17 and the suction cup control board 18 are electrically connected to the upper and lower sides of the internal battery 16 respectively, the spraying control board 17 is electrically connected to the spraying pump M114, the suction cup control board 18 is electrically connected to the suction cup vacuum pump M215, the vacuum tube 7 is connected to the top side of the suction cup vacuum pump M215, the spraying pigment pipe 13 is connected to one side of the spraying pump M114, the spraying pump M114 is communicated with the paint tank 8, the charging port 9 is electrically connected to the internal battery 16, the suction cup release button 10 is electrically connected to the suction cup control board 18, and the spraying work button 11 and the display screen 12 are electrically connected to the spraying control board 17.

[0016] The utility model working principle: divide into suction cup fixed work, two parts of spraying operation adjustment work.

[0017] The suction cup fixed work is that the suction cup is connected with the suction cup vacuum pump M215 in the inside of the spray printing box body 1 through the vacuum tube to carry out air extraction, strong negative pressure is formed, the vehicle surface is firmly adsorbed, so that the whole equipment can be fixed, after the fixed suction cup, the angle of the spray printing box body 1 can be adjusted through the live shaft part connected with the suction cup.

[0018] The diameter of the box body fixing chuck 2 is 150 mm, which is made of perfluorinated rubber and has the properties of high temperature resistance, low temperature resistance and aging resistance, and can adapt to an environment ranging from-40℃ to 80℃. After starting, the chuck vacuum pump M215 works, the box body fixing chuck 2 is connected to the built-in chuck vacuum pump M215 through the vacuum pipe 7 to extract air and form negative pressure, and is adsorbed on the surface of the vehicle. The chuck vacuum pump M215 is controlled by the chuck control panel 18 through a closed loop control of the pressure sensor. The pressure sensor is installed in the negative pressure cavity connected to the chuck pipeline and communicates with the connecting pipeline of the vacuum pump, and is used to monitor the pressure level in the chuck cavity in real time. During the adsorption process, the chuck vacuum pump M215 is started, and the air in the box body fixing chuck 2 is continuously extracted through the sealed pipeline system. After the negative pressure is formed, the chuck control panel 18 judges the adsorption state according to the data fed back by the pressure sensor, and automatically stops the operation of the pump when the set negative pressure threshold is reached. To prevent pressure drop, a leak-proof check valve is set to ensure that the vacuum state inside the cavity is maintained after the adsorption is completed. At the same time, the chuck control panel 18 has the functions of pressure monitoring and compensation: if the sensor detects that the pressure in the cavity of the box body fixing chuck 2 is lower than the safety threshold, the chuck control panel 18 will automatically restart the vacuum pump to compensate the pressure. To further ensure the reliability of adsorption, the assembly is also equipped with an alarm function. When the adsorption force drops to the critical value, the screen will issue an alarm prompt to ensure timely maintenance. The chuck base is designed as an adjustable joint, which facilitates the adjustment of the angle of the chuck connecting shaft 6. The box body fixing chuck 2 not only has strong adsorption capacity, but also is designed with a convenient release function to ensure that the equipment can be quickly and safely disassembled after the work is completed. The pipeline connected to the box body fixing chuck 2 is integrated with an electromagnetic valve in the negative pressure cavity, which is used to release the vacuum. When it is necessary to release, the user only needs to press the chuck release button 10, the chuck control panel 18 opens the electromagnetic release valve, and the outside air quickly enters the negative pressure cavity to eliminate the vacuum state, so that the chuck control panel 18 is separated from the surface of the vehicle.

[0019] The spraying part controls the on-off of the spraying pump M114 through the spraying control panel 17 to complete the spraying. When the spraying control panel 17 detects that the remote control module receives a start signal, the spraying pump M114 is started to spray, and when a stop signal is detected, the spraying pump M114 is stopped to spray. The signal is sent by external remote control, which is manually controlled by the operator. The spraying pump M114 selects a micro diaphragm pump.

[0020] The spraying operation adjustment work is divided into adjustment work and spraying work. The adjustment work is adjusted according to the outermost turning position of the vehicle, and the angle and position of the folding arm 3 and the folding universal shaft 4 are adjusted to finally adjust the angle of the spraying head 5 to the ground to be sprayed. The spraying work sucks the paint in the paint tank 8 through the spraying pump M114, and then pumps it to the spraying head 5 through the spraying paint pipe 13, so that the spraying head 5 sprays the paint. After the vehicle completes the turning, further measurement and deepening of the spraying work can be carried out through the mark on the ground.

[0021] The above is the preferred embodiment of the present application, for those skilled in the art, according to the teaching of the present application, without departing from the principles and spirit of the present application, the change, modification, replacement and modification of the embodiment still falls within the scope of the present application.
