[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 3 The utility model provides an embodiment: a paint spraying machine, including a cart 1, a mixing chamber 2 is placed on the outer wall above the cart 1, a hopper 3 is arranged on the top of the mixing chamber 2, the paint is put into the mixing chamber 2 through the hopper 3, the outer wall of the mixing chamber 2 is fixedly connected with a water pumping pipe 10, the raw materials in the mixing chamber 2 are extracted by the water pumping pipe 10, a spraying machine 17 is fixedly connected to the end of the water pumping pipe 10, a coating assembly is rotatably connected on the front end shaft of the spraying machine 17, the coating assembly includes two groups of paint rollers 11, the inner walls of the two groups of paint rollers 11 are rotatably connected to the outer wall of the front end shaft of the spraying machine 17, a nozzle 12 is provided at the front end of the spraying machine 17, the raw materials are sprayed out through the nozzle 12, and the sprayed paint is evenly spread by the paint roller 11, and the spraying machine 17 is used to spray the raw materials. Two groups of baffles 13 are slidably connected to the inner wall of the machine 17, and a block 15 is elastically connected to the inner wall of the baffle 13 through a return spring 14. One end of the return spring 14 is fixedly connected to the inner wall of the baffle 13, and the other end of the return spring 14 is fixedly connected to the inner end of the block 15. Pressing the block 15 inward can squeeze the return spring 14 to move inward. At the same time, the elastic force generated by the deformation of the return spring 14 gives the block 15 an outward thrust to reset it. A plurality of groups of slots 16 are provided on the inner wall of the spray brush machine 17, and the outer wall of the block 15 is snap-connected with the inner wall of the slot 16. When the two groups of blocks 15 are pressed inward until they are completely retracted into the baffle 13, the baffle 13 can be slid along the inner wall of the spray brush machine 17 to adjust the spraying area of ​​the spray brush machine 17.

[0028] Reference Figure 1 and Figure 4A motor 4 is welded to the top of the mixing bin 2, and a support plate 5 is fixedly connected to the output shaft of the motor 4. Two sets of rotating shafts 6 are rotatably connected to the inner wall of the support plate 5, and the outer walls of the two sets of rotating shafts 6 are fixedly connected to stirring mechanisms 9. Starting the motor 4 can make the two sets of stirring mechanisms 9 do circular motion with the output shaft of the motor 4 as the center, and stir the paint in the mixing bin 2 to make it mixed evenly and improve the spraying effect. An internal gear 8 is fixedly connected to the outer wall of the top of the rotating shaft 6, and an external gear 7 is fixedly connected to the inner wall of the top of the mixing bin 2. The outer wall of the internal gear 8 is meshed with the inner wall of the external gear 7. When the two sets of rotating shafts 6 make circular motion driven by the support plate 5, the internal gear 8 rotates under the action of the external gear 7, thereby driving the rotating shaft 6 and the stirring mechanism 9 to rotate, so that the mixing effect of the paint is better.

[0029] Working principle: put the paint into the mixing bin 2 through the hopper 3, start the motor 4 to make the support plate 5 drive the rotating shaft 6 and the stirring mechanism 9 to make a circular motion, and stir the paint in the mixing bin 2. At the same time, the inner gear 8 rotates under the action of the outer gear 7, driving the rotating shaft 6 to rotate, so that the two sets of stirring mechanisms 9 rotate while making a circular motion, so as to achieve a better mixing effect of the paint. Then, the paint is sprayed out by the spray brush 17, and it is evenly spread by the paint roller 11. When the spraying range needs to be adjusted, the two sets of card blocks 15 are pressed inward until they are released from the card slot 16 and the sliding baffle 13 is connected, and the spraying area of ​​the spray brush 17 is adjusted to meet different work requirements.
