DETAILED DESCRIPTION

Figure 2In the embodiment, the number of visual sensors 30 is set to two groups, and the two groups of visual sensors 30 are respectively installed at the upper and lower positions of the outer wall of the mixing chamber 10, so that the two groups of visual sensors 30 can respectively obtain images of the mixing of raw materials of different depths in the mixing chamber 10, so as to measure and judge whether the mixing degree of the bottom layer and the upper layer of raw materials in the mixing chamber 10 is similar. A partition plate 11 is formed in the inner cavity of the mixing chamber 10 to separate its inner cavity, and at least one group of feeding components 40 is installed above the partition plate 11, and the feeding components 40 are used to control the input of each component raw material constituting the water-based paint. A particle size analyzer can be set next to the mixing chamber 10, and it is connected to the inner cavity of the mixing chamber 10 by an online sampler, so that the particle size analyzer can take samples for analysis after the mixing and stirring, so as to assist in judging whether the mixing is uniform. The particle size analyzer can adopt the laser particle size analyzer already available in the prior art, which will not be repeated here.

[0019] In this embodiment, the feeding assembly 40 is respectively provided with a material storage portion 41, a dumping assembly, an opening and closing assembly and an anti-settling assembly.

[0020] The bottom of one side of the material storage part 41 is hinged to the mixing chamber 10 by means of a bottom bracket 42, and the top of the same side of the feeding assembly 40 is hinged to the output end of the driver 43, and the driver 43 is hinged to the inner wall of the mixing chamber 10 by means of a top bracket 44. The driver 43 is an electric push rod or a pneumatic push rod with a telescopically movable output end, so that the material storage part 41 can be tilted and moved above the partition plate 11. The bottom bracket 42, the driver 43 and the top bracket 44 constitute the pouring assembly of the feeding assembly 40.

[0021] A bottom partition 411 is formed at the inner lower part of the material storage part 41 to separate the inner cavity of the material storage part 41, and a material guide hole 412 communicating with the inner cavity of the material storage part 41 is also formed on the bottom wall of the material storage part 41 and the bottom partition 411. A rotatable driving shaft 45 driven by a motor is provided in the inner middle part of the material storage part 41, and a gear 46 is sleeved on the lower end of the driving shaft 45 and fixed thereto, and the gear 46 is provided between the bottom partition 411 and the inner bottom wall of the material storage part 41. An opening and closing tooth plate 47 meshing with the gear 46 is also provided between the bottom partition 411 and the inner bottom wall of the material storage part 41, and the opening and closing tooth plate 47 is slidably provided between the bottom wall of the material storage part 41 and the material guide hole 412 provided on the bottom partition 411, so that the gear 46 can drive the opening and closing tooth plate 47 to translate when rotating, thereby adjusting the connection and disconnection between the bottom wall of the material storage part 41 and the material guide hole 412 on the bottom partition 411. The driving shaft 45, the gear 46 and the opening and closing gear plate 47 constitute the opening and closing assembly of the feeding assembly 40, which is used to control whether the raw materials are poured out.

[0022] A plurality of fan blade structures are formed on the outer wall of the driving shaft 45, and the plurality of fan blade structures are all located between the bottom partition plate 411 and the top inner wall of the material storage portion 41. When the material guide hole 412 is opened or blocked and closed, the driving shaft 45 can drive the plurality of fan blade structures to rotate and mix the raw materials to a certain extent, thereby reducing the sedimentation of particles in the raw materials and forming an anti-sedimentation component of the feeding component 40.

[0024] The present application also discloses a method for processing water-based paint, which includes the following steps: Step 1: Input the raw materials of various components of water-based paint into a mixing chamber in appropriate proportions; Step 2, stirring and mixing the raw materials of the water-based paint input into the mixing chamber at an appropriate stirring speed by a mixer; Step 3: While step 2 is being performed, a single-view image extraction is performed on the mixing degree of each component raw material constituting the water-based paint in the mixing chamber by at least one group of visual sensors; Step 4: Preprocessing the single view image extracted in step 3 by a computer system to extract information to obtain the particle radius and color inside the mixed raw material; Step 5: Analyze the particle distribution and color change based on the information obtained in step 4, so as to obtain the uniformity of the mixing of the various components of the water-based paint input into the mixing chamber.

[0025] In this embodiment, during the image preprocessing of the single-view image in step 4, due to the random signal interference to the image during acquisition or transmission, which manifests as random changes in image information or pixel brightness, an image usually contains a lot of noise, which requires noise reduction processing. Therefore, the single-view image can first be filtered and denoised using linear filtering, median filtering or Wiener filtering.

[0026] In addition, in order to effectively improve the contrast and details of the image, the local contrast of the image obtained in the above steps can be enhanced, and when a pixel value in the image is larger than the average value of the surrounding pixels, the pixel value is increased; when a pixel value in the image is smaller than the average value of the surrounding pixels, the pixel value is reduced. The result value of such a processing process has nothing to do with the absolute value of the current pixel value, but is only related to the domain information, so that the contrast and details of the image can be effectively improved.

[0027] Finally, the image size needs to be processed. For example, the points where the brightness changes significantly in the digital image can be identified for edge detection.

[0028] After the image is preprocessed, the obtained image can be used to identify and locate particles, thereby determining the particle distribution inside the mixed raw material. The calculation formula is as follows: (r is the particle radius, A is the number of pixels of the particle in the image); The mean value of the particle distribution is calculated as: = ( is the average particle radius, N is the total number of particles, is the radius of each particle); The standard deviation of the particle distribution is calculated as: ( is the standard deviation of the particle radius).

[0029] By performing the above calculations on particles of different sizes extracted from the image and counting the standard deviation of the particle distribution in the image area, the smaller the standard deviation of the particle distribution, the more uniform the particle mixing is.

[0030] After the image is preprocessed, the obtained image can be divided into blocks, and the Euclidean distance calculation is performed on each block of the divided image to obtain the color difference inside the mixed raw material. The calculation formula is as follows: ( is the color difference between the two separated images, R1, G1, B1 and R2, G2, B2 are the values ​​of the two separated images in the RGB color space).

[0031] By comparing the colors of the block images one by one, The smaller the value of, the smaller the color difference between the two block images, and when the color difference between all block images is When the values ​​of are close to the same, it means that the raw materials are mixed evenly.

[0032] The present application also discloses a water-based paint, comprising 50-60 wt% of a water-dispersible paint matrix and 40-50 wt% of The sol dispersion can be mixed and stirred using the above-mentioned water-based paint processing system, and the mixing and stirring time can be controlled by the above-mentioned water-based paint processing method.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
