[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a paint spraying device, including a base plate 8, a mixing tank 5 above the base plate 8, multiple support rods 6 fixed to the bottom of the mixing tank 5, the bottom of the support rods 6 being fixedly connected to the top of the base plate 8, a pump 10 below the mixing tank 5, suction pipes 9 fixed to both ends of the pump 10, a spring tube 11 fixed to the other end of the suction pipe 9, a fixing tube 14 fixed to the other end of the spring tube 11, a rubber hose 13 fixed to the outer wall of the fixing tube 14, a spray pipe 15 fixed to the other end of the rubber hose 13, a throttling mechanism 12 on the outer side of the rubber hose 13, the throttling mechanism 12 including multiple pressure blocks 23, multiple threaded rods 24 and connecting rods 22, a fixing frame 16 located on the right side of the mixing tank 5 at the top of the base plate 8, a moving block 19 slidably connected inside the fixing frame 16, a screw rod 20 screwed to the moving block 19, the two ends of the screw rod 20 being rotatably connected to the upper and lower surfaces of the inside of the fixing frame 16 respectively, and a moving rod 20 fixed to the right end of the moving block 19. The two ends of the frame 18 and the fixed tube 14 are fixedly connected to the front and rear surfaces of the interior of the movable frame 18, respectively. The top of the fixed frame 16 is fixed with a lifting motor 17. The output shaft of the lifting motor 17 passes through the fixed frame 16 and is fixedly connected to the top of the screw 20. The interior of the mixing tank 5 is fixed with a fixed frame 2. The top of the fixed frame 2 is fixed with a stirring motor 1. The output shaft of the stirring motor 1 passes through the fixed frame 2 and is fixed with a stirring rod 4. The bottom of the base plate 8 is equipped with multiple casters 7. The interior of the mixing tank 5 is equipped with a feeding mechanism 3. The feeding mechanism 3 includes a fixed shell 27, a rotating block 29, multiple extrusion blocks 28 and a feeding hose 26. The lifting motor 17 and the pump 10 are started. The pump 10 draws out the paint from the interior of the mixing tank 5. The paint enters the spray pipe 15 through the suction pipe 9, the spring tube 11 and the rubber hose 13 and is sprayed out for spraying. The lifting motor 17 drives the screw 20 to rotate. The rotation of the screw 20 causes the movable block 19 and the movable frame 18 to move. The movable frame 18 moves up and down with the spray pipe 15 for moving spraying.

[0023] Furthermore, the two ends of the connecting rod 22 are fixedly connected to the left and right sides of the interior of the movable frame 18, respectively. The left side of the connecting rod 22 has multiple through holes 25, and the inner sidewall of the through holes 25 has a sliding groove 21. The pressure block 23 is slidably connected to the sliding groove 21. The threaded rod 24 is located inside the connecting rod 22 and is screwed to the connecting rod 22. The bottom of the threaded rod 24 is rotatably connected to the top of the pressure block 23. Rotating the threaded rod 24 causes it to move, which in turn moves the pressure block 23. When the threaded rod 24 and the pressure block 23 move downwards, they will squeeze the rubber hose 13, thus throttling the flow and preventing the paint from entering the spray pipe 15 and being sprayed out. This allows for adjustment of the spraying area.

[0024] Furthermore, the top of the fixed shell 27 and the bottom of the fixed frame 2 are fixedly connected. The rotating block 29 is located inside the fixed shell 27. The extrusion block 28 is fixed to the outer wall of the rotating block 29. The feeding hose 26 is fixed inside the fixed shell 27. Both ends of the feeding hose 26 pass through the fixed shell 27 respectively. The stirring rod 4 passes through the rotating block 29 and the fixed shell 27. The stirring rod 4 and the rotating block 29 are fixedly connected. The feeding hose 26 is inserted into the paint bucket. The stirring motor 1 is started. The stirring motor 1 drives the stirring rod 4 to rotate. The stirring rod 4 drives the rotating block 29 to rotate. The rotating block 29 drives the extrusion block 28 to rotate. The extrusion block 28 rotates and extrudes the feeding hose 26. In this way, the feeding hose 26 generates negative pressure and draws the paint from inside the paint bucket. The paint falls from the feeding hose 26 into the interior of the mixing tank 5. While the stirring rod 4 rotates, it stirs the paint inside the mixing tank 5.

[0025] During operation, the lifting motor 17 and the pump 10 are started. The pump 10 draws out the paint from the mixing tank 5. The paint passes through the suction pipe 9, spring pipe 11, and rubber hose 13 and enters the spray pipe 15 for spraying. The lifting motor 17 drives the screw 20 to rotate. The rotation of the screw 20 causes the moving block 19 and the moving frame 18 to move. The moving frame 18 moves the spray pipe 15 up and down for moving spraying. The threaded rod 24 is rotated, which moves the threaded rod 24 and the pressure block 23. The downward movement of the threaded rod 24 and the pressure block 23 squeezes the rubber hose 13, throttling the flow and preventing the paint from entering the spray pipe 15 for spraying. This allows for adjustment of the spraying area.
