Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of particle diameter detection, in particular to an automatic particle diameter detector for fluid liquid. Background Art
[0002] For fluid liquids such as glue, paint, and pigment, they are mainly composed of a mixture of water-soluble resins, solvents, organic pigments, and related additives; the water-dispersible binder in the above fluid liquids is obtained by polymerization of monomers emulsified in water. It is a two-phase system, in which the oil phase is dispersed in the water phase in the form of particles. Although it cannot be dissolved by water, it can be diluted by water and is considered to be an oil-in-water emulsion. The fineness and purity of the above fluid liquids have a great influence on the quality of printed products, and the fineness and purity are greatly affected by the particle size of the oil phase, so particle size detection is required.
[0003] At present, the existing technology for the particle size or fineness detection of liquids such as glue, paint, and pigment is specifically achieved by the scraper fineness meter method. The scraper fineness meter uses a stainless steel plate with a scale and a groove. The scraper fineness meter is manually placed on a flat surface, and the scraper surface is wiped 2-3 times with absorbent cotton dipped in alcohol; a sufficient amount of sample is dripped into the upper part, i.e., the deepest part of the groove, so that the groove can be filled with a little excess; then the thumb, index finger, and middle finger of both hands hold the scraper horizontally on the scraper fineness meter. The scraper is placed at the top of the meter, and the scraper is perpendicular to the surface of the scraper fineness meter. The scraper is pulled from the deep part of the groove to the shallow part at an appropriate speed, so that the sample fills the groove and no excess sample is left on the plate; as soon as possible after the scraper is pulled, the fineness meter is pinched horizontally and tilted, so that the line of sight forms an angle of 15-30° with the groove plane, and the light is observed where dense particle points first appear in the sample, especially in the 3mm wide strip across the groove, containing 5-10 particles; the reading value is the particle size or fineness of the measured object. The above technical solution has the following disadvantages: (1) Pure manual scraping is used, and a unified and standardized process cannot be formed, which is easy to cause errors in the test results due to inconsistent and non-standard actions; (2) When reading the particle size result, it is manually held and the line of sight is made to form a certain angle with the groove plane for reading, and factors such as light have a greater impact; (3) No image is saved during the data reading process, which is not convenient for later viewing and verification and electronic data summary. Therefore, in view of the above problems, an automatic particle size detector for fluid liquids is provided. Utility Model Content

[0028] See also Figure 1-6 As shown, the utility model is an automatic particle size detector for fluid liquid, comprising a base 101, a mounting frame 1 arranged on the base 101 and a scraper table 2 carrying a scraper fineness meter 3, a first lateral moving mechanism 503 installed on the rear side of the scraper table 2, a lifting mechanism 501 installed on a slider on the side of the first lateral moving mechanism 503, a connecting arm 502 arranged at the front of the lifting block of the lifting mechanism 501, a scraper 5 installed at the bottom of the front end of the connecting arm 502, a second lateral moving mechanism 606 installed on the upper part of the mounting frame 1, an industrial camera 6 installed on the slider at the bottom of the second lateral moving mechanism 606, a mounting plate 601 installed on the side of the industrial camera 6 and extending to the lower side of the industrial camera 6, and a main light source 603 and an auxiliary light source 602 installed on the mounting plate 601 for lighting the surface of the scraper fineness meter 3; a control host, a PLC controller, a motor drive and a power supply inlet are installed on the rear side of the scraper table 2 on the base 101;
[0029] The lateral movement direction of the first lateral moving mechanism 503 and the second lateral moving mechanism 606 is parallel to the scale direction of the scraper fineness meter 3 surface; the first lateral moving mechanism 503 and the second lateral moving mechanism 606 both adopt a screw mechanism; the first lateral moving mechanism 503 includes two limiting guide rods, a screw located between the two limiting guide rods, a side connecting block installed on the screw nut of the screw, and a first drive motor is installed at the end of the screw; the second lateral moving mechanism 503 includes a transversely arranged guide rail, a slider installed at the bottom of the guide rail and having a limiting structure, a screw installed in the guide rail, a ball nut installed on the screw and fixedly connected to the slider, and a second drive motor installed at the end of the screw;

[0031] Among them, a protective cover 4 for shielding the first horizontal moving mechanism 503, the industrial camera 6 and the auxiliary light source 602 is installed on the upper part of the mounting frame 1; the functions of the protective cover 4 are, first, protection to prevent the industrial camera 6 from being accidentally touched and hit, and second, to make the bottom lighting uniform; that is, when the light conditions are good, the main light source 603 can be directly used to obtain high-definition imaging effects, and in bad weather or darker environments, the auxiliary light source 602 is turned on at the same time to enhance the lighting effect.
