Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-6 As shown, the present invention proposes a mixing device for coating preparation, including a base 6, which can provide a solid support foundation for the entire device. A support frame 8 is installed on the side of the base 6 and is located on the same plane as its bottom. The support frame 8 is made of high-strength steel and is fixed to the base 6 by a combination of welding and bolt connection to ensure that the connection strength is sufficient to bear the weight of the upper components. The top of the support frame 8 is connected to the fixing plate 28 through the first support rod 9. A drive mechanism is installed on the fixing plate 28, and a protective shell 17 is installed on the top of the fixing plate 28 and on the outer end face of the drive mechanism. It also includes a second fixing plate 19 and a first fixing plate 12 distributed vertically. The second fixing plate 19 and the first fixing plate 12 are installed on the outer end face of the first support rod 9, and the second fixing plate 19 is connected to the bottom of the fixing plate 28. The two ends of the second fixing plate 19 and the first fixing plate 12 on opposite sides are vertically provided with sliding rods 13. The two sliding rods 13 are respectively connected to the mounting frame 21 through sliding sleeves 14 that are slidably connected to them. The mounting frame 21 is equipped with a stirring assembly. It also includes a threaded rod 18 arranged parallel to the slide rod 13. One end of the threaded rod 18 is rotatably connected to the upper end of the first fixed plate 12, and the other end of the threaded rod 18 passes through the second fixed plate 19 and is coaxially connected to the first gear 2. The outer end face of the threaded rod 18 is connected to the mounting bracket 21 through the lifting block 15 that is threadedly connected to it. It also includes symmetrically distributed placement plates 22, which are connected to each other by connecting plates 5. The upper moving end of the base 6 is connected to the symmetrically distributed placement plates 22 by a rotating mechanism. The upper ends of the placement plates 22 are respectively connected to the paint placement bucket 7 by limiting members.

[0026] In this utility model, the paint container 7 to be stirred is first installed on the placement plate 22 by a limiting member. The limiting hole 71 cooperates with the limiting block 222 to make the paint container 7 securely installed. Then, through the drive mechanism, the first motor 16 drives the second gear 29 to rotate, and the second gear 29 drives the first gear 2 to rotate through the toothed belt 24, thereby causing the threaded rod 18 to rotate. The lifting block 15 on the threaded rod 18 drives the mounting bracket 21 to move up and down along the slide rod 13 to adjust the height of the stirring assembly so that the stirring rod 27 of the stirring assembly is in a suitable position inside the paint placement tank 7. Then, the stirring assembly drives the stirring rod 27 to rotate, thereby stirring the paint inside the paint placement tank 7. When it is necessary to replace the paint placement tank 7, the rotating mechanism is started. The rotating mechanism can drive the connecting plate 5 and the placement plate 22 to rotate, so that the already mixed paint placement tank 7 is rotated out. At the same time, the new paint placement tank 7 to be mixed is rotated to the mixing position. When the already mixed paint placement tank 7 is taken out and replaced, the mixing component can continue to mix the new paint, which improves production efficiency.

[0027] The placement plate 22 is a rectangular steel plate with an anti-slip surface to prevent the paint placement bucket 7 from sliding on it. The symmetrically distributed placement plates 22 are connected by connecting plates 5 and welded together to form an integral structure, which improves the load-bearing capacity and stability of the placement plates 22. The upper moving end of the base 6 is connected to the symmetrically distributed placement plates 22 through a rotating mechanism. The rotating mechanism can drive the placement plates 22 to rotate around the central axis of the base 6, thereby realizing the position switching of the paint placement bucket 7.

[0028] In an optional embodiment, the side of the first support rod 9 is also connected to the top of the support frame 8 via the second support rod 10, and handles 1 are symmetrically distributed on the outer wall of the paint placement bucket 7. It should be noted that the second support rod 10 greatly enhances the bending resistance of the first support rod 9 and the stability of the overall structure. The paint container 7 has handles 1 symmetrically distributed on its outer wall. The handles 1 are made of plastic or metal and have a non-slip surface, making it easy for operators to carry and move the paint container 7, making it more convenient and labor-saving to use.

[0029] In an optional embodiment, the rotating mechanism includes a motor mounting slot 61 located in the middle of the upper end of the base 6, a drive motor 62 installed inside the motor mounting slot 61, and an annular sliding assembly. The output shaft of the drive motor 62 is connected to the middle of the lower end of the connecting plate 5, and the annular sliding assembly is installed between the symmetrically distributed placement plates 22 and the base 6.

[0030] It should be noted that the motor mounting slot 61 is a circular groove whose size matches that of the drive motor 62, allowing the drive motor 62 to be installed in it; The drive motor 62 is a servo motor, which features stable speed, wide speed range and high control precision. Its output shaft is connected to the middle of the lower end of the connecting plate 5 by a coupling. The coupling has a certain buffering and shock absorption effect, which can reduce the impact of the coaxiality error between the motor output shaft and the connecting plate 5 on the transmission.

[0031] The annular sliding assembly is installed between the symmetrically distributed placement plate 22 and the base 6, which can ensure that the placement plate 22 rotates smoothly.

[0032] In an optional embodiment, the annular sliding assembly includes an annular sliding sleeve 23, a connecting rod 3, and an annular sliding ring 25. There are two annular sliding rings 25 with different radii. The two annular sliding rings 25, the motor mounting groove 61, and the output shaft of the drive motor 62 are arranged concentrically. The bottoms of the two annular sliding rings 25 are connected to the base 6 through multiple spaced connecting rods 3. The bottoms of the symmetrically distributed placement plate 22 are connected to the two annular sliding rings 25 that are slidably connected to it through the annular sliding sleeve 23. It should be noted that there are two annular sliding rings 25 with different radii. They are made of wear-resistant cast iron and are precision machined to have a smooth and flat surface. The two annular sliding rings 25, the motor mounting slot 61, and the output shaft of the drive motor 62 are set at the same center to ensure the concentricity of the placement plate 22 when it rotates.

[0033] The bottoms of the two annular sliding rings 25 are connected to the base 6 by multiple spaced connecting rods 3. The connecting rods 3 are cylindrical rods that are evenly distributed at the bottom of the annular sliding rings 25 to form a stable support structure. The bottom of the symmetrically distributed placement plate 22 is connected to two annular sliding rings 25 via annular sliding sleeve 23. The annular sliding sleeve 23 is made of wear-resistant metal and has annular grooves that cooperate with the annular sliding rings 25. Lubricating grease can be added to the grooves to allow the annular sliding sleeve 23 to slide flexibly on the annular sliding rings 25, reduce frictional resistance during rotation, and ensure that the placement plate 22 rotates smoothly. The bottom of the annular sliding sleeve 23 is provided with a slot, and multiple connecting rods 3 are located in the slot. The spacing between the slots is smaller than the outer diameter of the annular sliding ring 25 and larger than the outer diameter of the connecting rods 3.

[0034] In an optional embodiment, the limiting member includes a limiting hole 71 opened at the bottom of the paint placement bucket 7, and an installation groove 221 adapted to the bottom of the paint placement bucket 7 is opened at the upper end of the placement plate 22. A limiting block 222 that cooperates with the limiting hole 71 is installed on the bottom wall of the installation groove 221. It should be noted that the limiting hole 71 is a polygonal hole, and its size matches that of the limiting block 222; The depth and shape of the mounting groove 221 are adapted to the size of the bottom of the paint placement bucket 7, so that the bottom of the paint placement bucket 7 can be embedded in it, which plays a role in initial positioning. When the paint container 7 is placed in the mounting groove 221, the limiting block 222 can be precisely inserted into the limiting hole 71 to achieve circumferential and axial limiting of the paint container 7, ensuring that it will not shake or shift during stirring and rotation.

[0035] In an optional embodiment, the stirring assembly includes a second motor 20 mounted on a mounting bracket 21, the output of which is coaxially connected to the stirring rod 27 via a reducer 26. It should be noted that the second motor 20 is a high-power variable frequency motor, which can provide sufficient power output and the speed can be adjusted as needed; The output end of the second motor 20 is coaxially connected to the stirring rod 27 via a reducer 26. The reducer 26 is a planetary gear reducer, which can convert the high speed of the second motor 20 into the appropriate speed required by the stirring rod 27 and increase the output torque so that it can stir the paint inside the paint container 7.

[0036] In an optional embodiment, a mounting plate 31 is mounted on the side of the mounting bracket 21, and an electric push rod 30 is mounted on the mounting plate 31. The telescopic shaft of the electric push rod 30 passes through the mounting plate 31 and is connected to the bucket lid 11. The stirring rod 27 passes through a pre-drilled through hole in the middle of the bucket lid 11. It should be noted that the lid 11 is made of stainless steel and its shape matches the opening of the paint container 7. A rubber sealing gasket is installed on the edge. When the stirring rod 27 descends to the stirring position, the electric push rod 30 can drive the lid 11 to descend as well, so that the lid 11 can fit tightly against the opening of the paint container 7 to prevent paint from splashing out during the stirring process.

[0037] In an optional embodiment, the drive mechanism includes a first motor 16 mounted on the bottom of the fixed plate 28, a second gear 29 coaxially connected to the output shaft of the first motor 16, and a toothed belt 24, wherein the first gear 16 and the second gear 29 are connected by a transmission via the toothed belt 24 that meshes with them.

[0038] It should be noted that the first motor 16 is fixed to the fixed plate 28 by bolts; when the first motor 16 is started, the first motor 16 can drive the second gear 29 to rotate, the rotating second gear 29 can be rotated by the first gear 2, the first gear 2 can drive the threaded rod 18 to rotate, thereby driving the lifting block 15 to rise and fall.

[0039] In an optional embodiment, an absolute encoder coaxially disposed with the output shaft of the drive motor 62 is also included.

[0040] It should be noted that the absolute encoder is electrically connected to the microcontroller, and its preset target angle threshold is 180°. When the absolute encoder detects that the motor rotation angle reaches 180°, the microcontroller sends a power-off signal to the drive motor 62, causing the motor to stop immediately and achieving precise positioning.

[0041] Working principle: When using this paint preparation mixing equipment, firstly, the paint container 7 to be mixed is installed on the placement plate 22 by the limiting component. The limiting hole 71 and the limiting block 222 cooperate to make the paint container 7 securely installed. Then, the first motor 16 is started, which drives the second gear 29 to rotate. The second gear 29 drives the first gear 2 to rotate through the toothed belt 24, which in turn causes the threaded rod 18 to rotate. The lifting block 15 on the threaded rod 18 drives the mounting frame 21 to move up and down along the slide rod 13 to adjust the height of the mixing component so that the mixing rod 27 is in a suitable position inside the paint container 7. Start the second motor 20. The second motor 20 drives the stirring rod 27 to rotate through the reducer 26, thereby stirring the coating. When it is necessary to replace the paint placement tank 7, the drive motor 62 is started. The drive motor 62 drives the connecting plate 5 and the placement plate 22 to rotate, rotating out the already mixed paint placement tank 7. At the same time, the new paint placement tank 7 to be mixed is rotated to the mixing position. When the already mixed paint placement tank 7 is taken out and replaced, the mixing component can continue to mix the new paint, which improves production efficiency. In addition, the absolute encoder can monitor the rotation angle and position of the output shaft of the drive motor 62 in real time to ensure that the placement plate 22 rotates accurately into place.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
