[0050] The present invention is further described in detail below with reference to the accompanying drawings.

[0051] like Figures 1 to 16 As shown, in order to solve the technical problem of "how to mix and stir the raw materials of polyurethane water-based coatings, and peel off the particles in the raw materials during the stirring process to improve the efficiency of filtering and stirring", the steps and functions of a polyurethane water-based coating preparation process are described in detail below;

[0052] A polyurethane water-based coating preparation process, the process comprising the following steps:

[0053] S1: Adding polyurethane water-based paint raw materials into the stirring chamber 21;

[0054] S2: stirring the polyurethane water-based paint raw material in the stirring chamber 21;

[0055] S3: filtering and separating the particles in the polyurethane water-based paint raw materials;

[0056] The specific steps of S2 are:

[0057] S21: driving the multiple sleeves 62 and the multiple rotating cylinders 65 in the stirring chamber 21 to rotate, so as to stir the polyurethane water-based paint raw material in the stirring chamber 21;

[0058] S22: driving the conical push block 51 slidably connected in the rotating cylinder 65 to reciprocate up and down, so as to continuously suck and discharge the polyurethane water-based paint raw material into and out of the rotating cylinder 65;

[0059] The specific steps of S3 are:

[0060] S31: driving the conical push block 51 slidably connected in the rotating cylinder 65 to move downward, and the polyurethane water-based paint raw material is discharged from the rotating cylinder 65;

[0061] S32: rotating the rotating drum 65 to switch the filtering area of ​​the rotating drum 65, thereby leaving the particles in the rotating drum 65;

[0062] S33: The particles are discharged through the circular cavity II 81 connected to the rotating cylinder 65.

[0063] When in use, the polyurethane water-based paint raw material to be processed is placed in the stirring chamber 21, the driving shaft 32 is driven to rotate, the driving shaft 32 drives the rotating disk I31 to rotate, the rotating disk I31 drives the multiple sleeves 62 and the multiple rotating cylinders 65 to rotate, and then the multiple sleeves 62 and the rotating cylinders 65 move in the stirring chamber 21, thereby mixing the multiple polyurethane water-based paint raw materials;

[0064] Further, the telescopic mechanism 41 is started. The telescopic mechanism 41 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism 41 drives the sliding ring 42 to move. The sliding ring 42 drives the sliding block 52 to move. The sliding block 52 pushes the conical push block 51 to slide in the rotating cylinder 65. When the conical push block 51 moves upward, the polyurethane water-based paint raw material is sucked into the rotating cylinder 65, thereby increasing the flow of the polyurethane water-based paint raw material, thereby increasing the stirring effect of the rotating cylinder 65. When the conical push block 51 moves downward, the conical push block 51 squeezes the space in the rotating cylinder 65, and the polyurethane water-based paint raw material in the rotating cylinder 65 is discharged, thereby increasing the flow of the polyurethane water-based paint raw material, thereby increasing the stirring effect of the rotating cylinder 65.

[0065] Furthermore, before the polyurethane water-based paint raw material is discharged from the rotating cylinder 65, the driving cylinder 33 is rotated. When the driving cylinder 33 rotates, the multiple rotating cylinders 65 are driven to rotate, and the multiple rotating cylinders 65 and the multiple sleeves 62 are misaligned, thereby adjusting the filtering area of ​​the rotating cylinder 65, thereby leaving the particles in the rotating cylinder 65, and discharging the particles through the circular cavity II 81 connected to the rotating cylinder 65, thereby completing the stirring and quickly discharging the particles in the polyurethane water-based paint raw material, thereby increasing the work efficiency;

[0071] A telescopic mechanism 41 is fixedly connected to the closed top plate 25, and a sliding ring 42 is fixedly connected to the telescopic end of the telescopic mechanism 41;

[0072] The sliding ring 42 is slidably connected to a plurality of sliding blocks 52, and the lower end of each sliding block 52 is rotatably connected to a conical push block 51, and the plurality of conical push blocks 51 respectively pass through a plurality of support plates 67 and are slidably connected to the rotating cylinder 65;

[0076] Furthermore, in order to increase the fluidity of the polyurethane water-based paint raw material, the power mechanism I can be started, and the output shaft of the power mechanism I drives the rotating ring 12 to swing, and the rotating ring 12 drives the stirring cavity 21 to swing, thereby increasing the fluidity of the polyurethane water-based paint raw material in the stirring cavity 21, thereby further increasing the stirring effect;

[0077] The telescopic mechanism 41 is started. The telescopic mechanism 41 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism 41 drives the sliding ring 42 to move. The sliding ring 42 drives the sliding block 52 to move. The sliding block 52 drives the conical push block 51 to move. The conical push block 51 slides in the corresponding rotating cylinder 65.

[0079] Furthermore, a filter hole Ⅰ 64 is provided, and the filter hole Ⅰ 64 and the suction hole Ⅱ 66 can be controlled to overlap by starting the power mechanism Ⅲ, which can also play the effect of controlling the filter area;

[0080] When the conical push block 51 moves downward to the limit state, the side of the conical push block 51 blocks the suction hole II 66, so that the particles in the polyurethane water-based paint raw material remain between the conical push block 51 and the concave pressure plate 73;
