Technical Field

[0002] A color mixing machine is a device used to mix different colored paints in a certain proportion to create the desired color. Traditional color mixing machines typically include a mixing container and a stirring device, which mixes the paints evenly through rotation. This equipment is widely used in paint production, automotive repair, and architectural decoration, effectively improving color mixing efficiency and accuracy. However, with increasing application demands and technological advancements, traditional color mixing machines have gradually revealed some shortcomings.
[0003] In practical use, traditional color mixing machines have some obvious drawbacks. First, during the mixing process, paint tends to adhere to the inner wall of the mixing container, resulting in uneven mixing and affecting the color mixing effect. Moreover, cleaning the paint on the inner wall is difficult, which not only increases cleaning costs but may also lead to paint residue, affecting the accuracy of the next color mixing. Second, traditional color mixing machines mostly use manual control or simple flow control to control the paint feeding, lacking a precise color mixing structure. This can easily lead to errors when mixing complex colors or requiring high-precision color mixing, affecting the final color effect. Utility Model Content

[0024] 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.
[0025] Example 1
[0026] Please see Figure 1-7 The present invention provides the following technical solution: a color mixing machine with an inner wall cleaning structure, including a mounting plate 1, the mounting plate 1 being fixedly connected to the wall by bolts 6, a connecting plate 2 being provided on the side of the mounting plate 1, a color mixing machine 4 being provided at the other end of the connecting plate 2, a discharge pipe 7 being provided on the lower side of the color mixing machine 4, a valve 8 being provided on the side of the discharge pipe 7, a stirring mechanism 3 being provided inside the mounting plate 1, and a paint feeding mechanism 5 being provided at the upper end of the mounting plate 1;
[0027] The stirring mechanism 3 includes a hollow tube 31, which is rotatably connected to the interior of the color mixing machine 4. A transmission assembly 36 is provided at the upper end of the hollow tube 31. Multiple sets of stirring blades 33 are provided on the surface of the hollow tube 31. An outer rod 35 is provided on the side of the hollow tube 31 near the stirring blades 33. An inner rod 34 is slidably connected to the side of the outer rod 35 from the inside to the outside. A cleaning brush 32 is provided at the other end of the inner rod 34. An electromagnetic adsorption assembly 38 is provided inside the outer rod 35. A rigid wire 39 is provided inside the hollow tube 31. A wire connection assembly 37 is provided at the center of the lower end of the color mixing machine 4.
[0028] Specifically, the transmission assembly 36 includes a motor 366. The motor 366 is located on the upper side of the color mixing machine 4. A drive shaft 365 is located at the output end of the motor 366. A mounting box 364 is located at the upper interior of the color mixing machine 4. A fixing rod 362 is located on the side of the mounting box 364 and is fixed to the inner wall of the color mixing machine 4. The other end of the drive shaft 365 is located inside the mounting box 364 and has a bevel gear 363. A second bevel gear 361 that meshes with the first bevel gear 363 is located on the upper surface of the hollow tube 31.
[0029] By adopting the above technical solution, the efficient operation of the stirring mechanism 3 is achieved. The motor 366 drives the bevel gear 363 to rotate through the drive shaft 365. The bevel gear 363 meshes with the bevel gear 361, thereby driving the hollow tube 31 and the stirring blades 33 on its surface to rotate, so as to achieve full mixing of the paint. This transmission method not only ensures the uniformity of mixing, but also improves the mixing efficiency, ensuring that the paint can be fully mixed during the color matching process to achieve the ideal color matching effect.
[0030] Specifically, the mounting box 364 has a corresponding round hole inside the hollow tube 31 and is rotatably connected to it; the lower center of the color mixing machine 4 has a corresponding round hole at the rigid wire 39 and is rotatably connected to it.
[0031] By adopting the above technical solution, the stable rotation of the hollow tube 31 and the rigid wire 39 is ensured. The design of the round hole allows the hollow tube 31 and the rigid wire 39 to rotate smoothly inside the color mixing machine 4, reducing friction and wear during rotation and improving the service life and operational reliability of the device.
[0032] Specifically, the electromagnetic adsorption assembly 38 includes an electromagnet 381. The other end of the rigid wire 39 is located inside the outer rod 35 and the electromagnet 381 is installed inside it. A central rod 382 is provided on the side of the electromagnet 381. A spring 383 is sleeved on the surface of the central rod 382. A mounting hole 384 corresponding to the spring 383 is opened on the side of the inner rod 34.
[0033] By adopting the above technical solution, the automatic extension and retraction function of the cleaning brush 32 is realized. When the electromagnet 381 is energized, it generates a magnetic field that attracts the inner rod 34, so that the cleaning brush 32 is in close contact with the inner wall of the color mixing machine 4 to perform cleaning work. When the electromagnet 381 is de-energized, the elastic force of the spring 383 pushes the inner rod 34 to move outward, so that the cleaning brush 32 is away from the inner wall, which facilitates the normal rotation of the stirring blade 33. This design not only improves the cleaning efficiency, but also reduces the tedious steps of manual operation.
[0034] Specifically, the wire connection assembly 37 includes a mounting block 374. The mounting block 374 is located at the lower center of the color mixing machine 4. The lower end of the rigid wire 39 is located inside the mounting block 374 and has a second conductive plate 373. The lower end of the mounting block 374 has a first conductive plate 372, and the lower end of the first conductive plate 372 has a main guide wire 371.
[0035] By adopting the above technical solution, a stable connection between the rigid conductor 39 and the external power supply is achieved. The setting of conductive plate 372 and conductive plate 373 ensures the stable transmission of current. The main conductor 371 introduces the current into the color mixing machine 4 to provide power support for electrical components such as electromagnet 381. This connection method not only ensures the reliability of the electrical connection, but also facilitates the maintenance and replacement of the conductor.
[0036] In this embodiment, the paint to be tinted is first added to the color mixing machine 4 through the paint feeding mechanism 5. The motor 366 is started, and the stirring blade 33 is rotated through the transmission component 36 to stir the paint. During the stirring process, the electromagnet 381 is energized, attracting the inner rod 34, so that the cleaning brush 32 is in close contact with the inner wall of the color mixing machine 4 for cleaning. After the stirring is completed, the electromagnet 381 is de-energized, the spring 383 pushes the inner rod 34 to move outward, the cleaning brush 32 moves away from the inner wall, and the stirring blade 33 continues to rotate, discharging the tinted paint through the discharge pipe 7. Throughout the process, the wire connection component 37 ensures a stable power supply to the electromagnet 381, improving the automation level and ease of use of the color mixing machine 4.
[0037] Example 2
[0038] The difference between this embodiment and Embodiment 1 is that: the paint feeding mechanism 5 includes a color mixing tray 56, the upper end of the color mixing machine 4 is provided with the color mixing tray 56, the upper end of the color mixing tray 56 is provided with a color mixing tube 57, the lower end surface of the color mixing tray 56 is provided with a flange 55, the flange 55 is fixedly connected to the color mixing machine 4 by bolt 2 54, the lower end of the color mixing tray 56 is provided with a feeding pipe 53, and the side of the feeding pipe 53 is provided with a valve 2 52.
[0039] By adopting the above technical solution, precise feeding of paint is achieved. The color mixing tray 56 is fixedly connected to the color mixing machine 4 through the flange 55, and the structure is stable and reliable. The color mixing tube 57 is used to add paint of different colors into the color mixing tray 56. The feed tube 53 guides the paint in the color mixing tray 56 into the color mixing machine 4. Valve 52 is used to control the amount of paint fed, ensuring the accuracy and consistency of the color mixing process.
[0040] Specifically, a through hole 51 corresponding to valve 2 52 is provided at the center of the upper end of the color mixing machine 4.
[0041] By adopting the above technical solution, the connectivity between the feeding pipe 53 and the interior of the color mixing machine 4 is ensured. The design of the through hole 51 allows the paint to enter the interior of the color mixing machine 4 smoothly. The valve 2 52 controls the feeding of the paint through the through hole 51, which further improves the automation level and ease of operation of the color mixing machine 4.
[0042] In this embodiment, different colored paints are added to the mixing tray 56 through the mixing tube 57. According to the required color ratio, valve 2 52 is opened, and the paint is introduced into the mixing machine 4 through the feeding tube 53. By controlling the opening of valve 2 52, the feeding amount of each paint can be precisely controlled to ensure the accuracy of color mixing. After color mixing is completed, the stirring mechanism 3 stirs the paint to make it fully mixed and achieve the ideal color mixing effect. Finally, the mixed paint is discharged through the discharge tube 7 to complete the entire color mixing process.
[0043] The working principle and usage process of this utility model are as follows: In use, the paint to be tinted is first added to the color mixing machine 4 through the paint feeding mechanism 5. The motor 366 is started, and the transmission assembly 36 drives the stirring blades 33 to rotate, stirring the paint. During stirring, the electromagnet 381 is energized, attracting the inner rod 34, causing the cleaning brush 32 to adhere tightly to the inner wall of the color mixing machine 4 for cleaning. After stirring is complete, the electromagnet 381 is de-energized, the spring 383 pushes the inner rod 34 outward, the cleaning brush 32 moves away from the inner wall, and the stirring blades 33 continue to rotate, discharging the tinted paint through the discharge pipe 7. Throughout the entire process… The wire connection assembly 37 ensures a stable power supply to the electromagnet 381, improving the automation level and ease of use of the color mixing machine 4. Different colored paints are added to the color mixing tray 56 through the color mixing tube 57. According to the required color ratio, valve 2 52 is opened, and the paint is introduced into the color mixing machine 4 through the feed pipe 53. By controlling the opening of valve 2 52, the feed amount of each paint can be precisely controlled to ensure the accuracy of color mixing. After color mixing is completed, the stirring mechanism 3 stirs the paint to make it fully mixed and achieve the ideal color mixing effect. Finally, the mixed paint is discharged through the discharge pipe 7, completing the entire color mixing process.
