DETAILED DESCRIPTION

[0023] The utility model is further illustrated in connection with the drawings and examples as follows:

[0024] Example 1: a spraying robot spraying area adjusting device, referring to Figures 1 to 6 , including robot body 1 and the spraying assembly 2 installed on the robot body 1, the robot body 1 is six-axis mechanical arm, the spraying assembly 2 is connected in the end of robot body 1, the spraying assembly 2 includes spraying pipe 21 and the driving motor 24, adjusting disc 22 and cleaning assembly installed on the spraying pipe 21, the driving end of driving motor 24 is connected with the one end center of adjusting disc 22, one end of adjusting disc 22 is movably abutted with one end of spraying pipe 21, adjusting disc 22 is divided into four regions and is provided with spraying hole 23 on each region, and the hole diameter size and quantity of spraying hole 23 on four regions are different.

[0025] When working, driving motor 24 drives adjusting disc 22 to rotate, so that the spraying hole 23 on each region is corresponded with spraying pipe 21, so that the area of spraying hole 23 in different regions is different after coating is transported through spraying pipe 21, and then the spraying area of coating can be automatically adjusted according to the area of workpiece spraying, further solve the problem that the existing nozzle only has single spraying area and cannot be applied to different size workpieces, and the applicability is poor.

[0026] The cleaning assembly in the embodiment comprises a protective cover 3 in the shape of a sector, which is sleeved on the top outer side of the adjusting disc 22, a fixing rod 35 is connected between the protective cover 3 and the spraying pipe 21, a gas pump 31 is installed on the top of the protective cover 3, a gas inlet pipe 32 is in communication between the gas outlet end of the gas pump 31 and one end of the protective cover 3, and a gas outlet pipe 33 is in communication with the end of the protective cover 3 away from the gas inlet pipe 32. When the adjusting disc 22 is rotated to adjust different spraying holes 23, the used spraying hole 23 is rotated to be positioned in the protective cover 3, and then the gas pump 31 is started to blow into the protective cover 3 through the gas inlet pipe 32, and then the gas is discharged through the gas outlet pipe 33, so that the residual paint in the used spraying hole 23 can be blown away in the reverse direction, thereby avoiding the residual paint in the used spraying hole 23, causing blockage and unable to be used next time.

[0027] In the embodiment, a first sealing gasket 36 is installed on the inner wall of the protective cover 3, the first sealing gasket 36 has elasticity, and is in movable abutment with the outer side of the adjusting disc 22.
