[0020] Please see Figs. 1-2 This embodiment provides a technical solution: a disperser for producing waterborne polyurethane paint, comprising a base 1 and a dispersing mechanism 3;
[0021] Base 1: A lifting mechanism 2 is provided on its front side. An upper base 9 is fixedly connected to the upper end of the lifting mechanism 2. The lifting mechanism 2 includes a sliding column 21, a hydraulic box 22 and a hydraulic cylinder 23. A hydraulic box 22 is fixedly connected to the front side of the base 1. A hydraulic cylinder 23 is fixedly connected to the bottom wall of the hydraulic box 22. The upper end of the telescopic end of the hydraulic cylinder 23 passes through the through hole of the top wall of the hydraulic box 22 and is fixedly connected to the upper base 9. The lower surface of the upper base 9 is fixedly connected with evenly distributed sliding columns 21. The sliding columns 21 are slidably connected to the inside of the sliding hole at the upper end of the hydraulic box 22. The oil inlet of the hydraulic cylinder 23 is connected to an external oil pump. When the telescopic end of the hydraulic cylinder 23 retracts, the upper base 9 and the sliding column 21 descend.
[0022] Dispersion mechanism 3 includes a motor 31, bearing seats 32, slide seats 33, slide rails 34, transmission shafts 35, and dispersion components 36. The bottom wall of the upper base 9 is fixedly connected to evenly distributed slide rails 34. Slide seats 33, symmetrically distributed left and right, are slidably connected between the upper ends of the slide rails 34. The upper ends of each slide seat 33 are fixedly connected to a motor 31 and symmetrically distributed bearing seats 32. A transmission shaft 35 is rotatably connected between two bearing seats 32 located on the same slide seat 33. The output shaft of the motor 31 is fixedly connected to the rear end of the transmission shaft 35 located on the same slide seat 33. The front end of each transmission shaft 35 is provided with a dispersion component. The dispersion assembly 36 includes a transmission base 361, a first bevel gear 362, a second bevel gear 363, a third bevel gear 364, an outer rotating shaft 365, an inner rotating shaft 366, and a dispersion disc 367. The middle part of the rear end of the transmission base 361 is rotatably connected to the adjacent transmission shaft 35 on the rear side. The front end of each transmission shaft 35 is fixedly sleeved with a first bevel gear 362. The lower end of each transmission base 361 is rotatably connected to an outer rotating shaft 365, which passes through a clearance groove in the bottom wall of the upper base 9. The upper end of each transmission base 361 is rotatably connected to an inner rotating shaft 366, and the lower end of the inner rotating shaft 366 is rotatably connected to... Inside the vertically adjacent outer rotating shafts 365, the upper end of the inner rotating shaft 366 is fixedly fitted with a bevel gear 364, and the upper end of the outer rotating shaft 365 is fixedly fitted with a bevel gear 363.

A bracket 7 is fixedly connected between the inner walls of the left and right sides of the upper base 9. Guide rails 8 are fixedly connected to the upper and lower ends of the front side of the bracket 7. The two transmission seats 36... 1. All are slidably connected between two guide rails 8. After all the dispersion discs 367 are immersed to a certain depth in the water-based polyurethane paint raw material, the upper base 9 no longer descends. Then, the output shaft of motor 1 31 drives the transmission shaft 35 to rotate, and the bevel gear 1 362 rotates. The bevel gear 2 363 and bevel gear 364 located in the same transmission base 361 are driven to rotate in opposite directions, driving the outer rotating shaft 365 and the inner rotating shaft 366 located inside it to rotate in opposite directions. The dispersion discs 367 rotate, stirring and dispersing the water-based polyurethane paint raw material. At the same time, the installation height of the dispersion discs 367 is different, increasing the shear force on the water-based polyurethane paint raw material.
[0023] It also includes a controller 6, which is located on the rear side of the base 1. The input terminal of the controller 6 is electrically connected to an external power source, and the input terminals of the motor 31 are all electrically connected to the output terminal of the controller 6.

The middle part of the lead screw seat 43 is threadedly connected to the left and right ends of the bidirectional lead screw 42, respectively. The second motor 41 is fixedly connected to the left side of the upper base 9. The output shaft of the second motor 41 is fixedly connected to the left end of the bidirectional lead screw 42. The input end of the second motor 41 is electrically connected to the output end of the controller 6. The output shaft of the second motor 41 drives the bidirectional lead screw 42 to rotate, thereby adjusting the spacing between the two lead screw seats 43. The two slides 33 slide synchronously between the slide rails 34, thereby driving the two transmission seats 361 to slide relative to each other between the two guide rails 8. As the position of the transmission seat 361 changes, the rotational positions of the outer rotating shaft 365 and the inner rotating shaft 366 change, and the lateral position of the dispersion disk 367 changes, making the stirring force of the water-based polyurethane paint raw material more complex and achieving more efficient dispersion.
[0025] The system also includes a ranging sensor 5. The receiving end of the ranging sensor 5 is fixedly connected to the upper surface of the left slide 33, and the transmitting end of the ranging sensor 5 is fixedly connected to the upper surface of the right slide 33. The left and right positions of the receiving end and the transmitting end of the ranging sensor 5 are corresponding. The receiving end of the ranging sensor 5 is bidirectionally electrically connected to the controller 6, and the input end of the transmitting end of the ranging sensor 5 is electrically connected to the output end of the controller 6. The receiving end and the transmitting end of the ranging sensor 5 detect the distance change in real time and feed it back to the controller 6, thereby realizing the precise distance adjustment of the two transmission seats 361.
[0026] The working principle of the disperser for producing water-based polyurethane paint provided by this utility model is as follows: A bucket containing the water-based polyurethane paint raw material is placed at the lower end of the outer rotating shaft 365. The telescopic end of the hydraulic cylinder 23 retracts, causing the upper base 9 and sliding column 21 to descend. After the entire dispersion disc 367 is immersed to a certain depth in the water-based polyurethane paint raw material, the upper base 9 stops descending. Subsequently, the output shaft of motor 1 31 drives the transmission shaft 35 to rotate, causing bevel gear 1 362 to rotate. Bevel gears 2 363 and 3 364, located on the same transmission base 361, are driven to rotate in opposite directions, causing the outer rotating shaft 365 and the inner rotating shaft 366 located inside it to rotate in opposite directions. The dispersion disc 367 rotates, thus stirring and dispersing the water-based polyurethane paint raw material. The dispersion is achieved by dispersing the water-based polyurethane paint raw materials at different installation heights on the dispersion discs 367. The output shaft of motor 41 drives the bidirectional lead screw 42 to rotate, which in turn adjusts the distance between the two lead screw seats 43. The two slide seats 33 slide synchronously between the slide rails 34, which in turn drives the two transmission seats 361 to slide relative to each other between the two guide rails 8. The receiving and transmitting ends of the distance measuring sensor 5 detect the distance change in real time and feed it back to the controller 6, thereby achieving precise distance adjustment of the two transmission seats 361. As the position of the transmission seats 361 changes, the rotation positions of the outer rotating shaft 365 and the inner rotating shaft 366 change, and the lateral position of the dispersion discs 367 changes, making the stirring force of the water-based polyurethane paint raw materials more complex and achieving more efficient dispersion.
[0027] It is worth noting that the controller 6 disclosed in the above embodiments can be selected, motor 31 can be selected, motor 41 can be selected, and distance sensor 5 can be selected. The control switch group controls the operation of the fan 2 and motor 31 using methods commonly used in the prior art. The control switch group 10 is equipped with switch buttons corresponding to motor 21, motor 71 and push rod 32 for controlling their switching operation.
