Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond micro powder sorting and detection, and more specifically, to a particle size detection mechanism for diamond micro powder sorting machines. Background Technology
[0002] Diamond micron powder, a fine superhard abrasive, refers to diamond particles with a size finer than 54 micrometers. Among them, single-crystal diamond micron powder has attracted much attention due to its large production volume and wide application. It is produced by crushing and shaping synthetic single-crystal diamond abrasive grains using the hydrostatic pressing method, and employing special processes for superhard materials. With its high hardness and good wear resistance, it is widely used in cutting, grinding, drilling, polishing and other fields, and is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass.
[0003] Existing devices rely on the uniformity of the suspension after sample dispersion. Diamond micro powder particles are very small and are prone to agglomeration due to factors such as electrostatic adsorption and intermolecular forces, resulting in uneven sample dispersion. If the dispersion is insufficient, the detection value will be too large or too small, resulting in a large error in the subsequent particle size detection results, which will affect the product grading and application effect.
[0004] Therefore, it is necessary to redesign the particle size detection mechanism of the diamond micro powder separator to address the above-mentioned issues. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a particle size detection mechanism for a diamond micro powder sorting machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The particle size detection mechanism of the diamond micron powder separator includes a sorting box and a feeding box. The feeding box is fixedly installed on the upper end face of the sorting box. A cover plate is fixedly installed on the upper end face of the feeding box. A fixed shaft is rotatably connected to the bottom end of the cover plate. A fixed sleeve is fixedly installed on the outer wall of the fixed shaft. Two push plates are symmetrically fixedly connected to the outer wall of the fixed sleeve. Two connecting rods are symmetrically fixedly installed on the outer wall of the fixed sleeve. An installation groove is opened at one end of each connecting rod. A scraping device is provided in each installation groove. Two discharge ports are symmetrically opened on the inner bottom wall of the feeding box, and the two discharge ports are respectively connected to the sorting box. A stirring device is installed at the bottom end of the fixed shaft, which rotatably passes through the inner bottom wall of the feeding box and extends into the sorting box.
[0008] In a preferred embodiment, each of the scraping devices includes a spring, which is fixedly connected to the inner wall of the mounting groove. One end of the spring is fixedly connected to a connecting rod, which is slidably connected within the mounting groove. The end of the connecting rod away from the spring is fixedly connected to a first scraper, which contacts the inner wall of the feeding box.
[0009] In a preferred embodiment, the stirring device includes a drive shaft, which is fixedly connected to the bottom end of a fixed shaft. A drive sleeve is fixedly installed on the outer wall of the drive shaft, and a plurality of stirring blades are circumferentially arranged on the outer wall of the drive sleeve.
[0010] In a preferred embodiment, a fixing rod is fixedly installed on each of the stirring blades, and a second scraper is fixedly installed on the end of the fixing rod away from the stirring blade, and the second scraper is in contact with the inner wall of the sorting box.
[0011] In a preferred embodiment, a mounting bracket is fixedly installed on the upper end face of the cover plate, and a motor is fixedly installed on the mounting bracket. The output shaft of the motor rotates through the upper end face of the cover plate and is fixedly connected to the top end of the fixed shaft.
[0012] In a preferred embodiment, the upper end face of the cover plate is provided with a feed inlet.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting up a fixed shaft, push plate, feeding trough, stirring device and other devices, effectively prevents the agglomeration of diamond micro powder through the dual action of stirring by the push plate in the feeding box and secondary dispersion by the stirring blades in the sorting box, so as to make the micro powder uniformly dispersed and provide high-quality samples for particle size detection.
[0015] 2. This utility model uses a scraping device, a second scraper, and other devices to continuously scrape off the adhering micro powder with the first and second scrapers, preventing material residue from accumulating, reducing the frequency of manual cleaning, and lowering equipment maintenance costs.
[0016] In summary, this utility model is simple to operate. The combination of the pusher plate and the stirring device can prevent the diamond powder from agglomerating and ensure the uniformity of the powder. The first scraper and the second scraper continuously scrape off the adhering powder to prevent material residue from accumulating, reduce the frequency of manual cleaning, reduce equipment maintenance costs, and avoid residual particles interfering with detection.

Detailed Implementation
[0023] 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.
[0024] Reference Figure 1-5 The diamond micro powder separator particle size detection mechanism includes a sorting box 1 and a feeding box 2. The feeding box 2 is fixedly installed on the upper end face of the sorting box 1. A cover plate 3 is fixedly installed on the upper end face of the feeding box 2. A fixed shaft 7 is rotatably connected to the bottom end of the cover plate 3. A fixed sleeve 8 is fixedly installed on the outer wall of the fixed shaft 7. Two push plates 9 are symmetrically fixedly connected on the outer wall of the fixed sleeve 8. The two push plates 9 move in a circular motion under the drive of the fixed shaft 7 to stir and push the diamond micro powder in the feeding box 2 laterally, break the agglomeration of micro powder, achieve preliminary dispersion, and at the same time push a portion of micro powder evenly into the discharge port 11.
[0025] Two connecting rods 10 are symmetrically fixed on the outer wall of the fixed sleeve 8. Each connecting rod 10 has an installation groove 17 at one end. Each installation groove 17 is equipped with a scraping device. Two discharge ports 11 are symmetrically opened on the inner bottom wall of the feeding box 2. The two discharge ports 11 are respectively connected to the sorting box 1. The bottom end of the fixed shaft 7 rotates through the inner bottom wall of the feeding box 2 and extends into the sorting box 1 to install a stirring device.
[0026] Each scraping device includes a spring 18, which is fixedly connected to the inner wall of the mounting groove 17. One end of the spring 18 is fixedly connected to a connecting rod 19, which is slidably connected within the mounting groove 17. The end of the connecting rod 19 away from the spring 18 is fixedly connected to a first scraper 20, which contacts the inner wall of the feeding box 2. The spring 18 provides continuous elastic force to the first scraper 20, ensuring that the scraper fits tightly against the inner wall of the feeding box 2. When the fixed shaft 7 rotates, the connecting rod 10 drives the first scraper 20 to slide along the inner wall of the feeding box 2. The elastic adaptive capability of the spring 18 ensures that the first scraper 20 maintains good fit even after slight wear occurs during long-term operation of the equipment.
[0027] The stirring device includes a drive shaft 12, which is fixedly connected to the bottom end of the fixed shaft 7. A drive sleeve 13 is fixedly installed on the outer wall of the drive shaft 12. Multiple stirring blades 14 are arranged circumferentially on the outer wall of the drive sleeve 13. The stirring blades 14 can perform longitudinal stirring and shearing dispersion on the micro powder entering the sorting box 1.
[0028] Each stirring blade 14 is fixedly mounted with a fixing rod 15. A second scraper 16 is fixedly mounted on the end of the fixing rod 15 away from the stirring blade 14, and the second scraper 16 is in contact with the inner wall of the sorting box 1.
[0029] A mounting bracket 4 is fixedly installed on the upper end face of the cover plate 3. A motor 5 is fixedly installed on the mounting bracket 4, and the output shaft of the motor 5 rotates through the upper end face of the cover plate 3 and is fixedly connected to the top end of the fixed shaft 7.
[0030] The upper end face of the cover plate 3 is provided with a feed inlet 6, through which diamond micro powder can be fed into the feeding box 2.
[0031] When this utility model is in use, when the motor 5 starts, its output shaft drives the fixed shaft 7 to rotate. Since the fixed sleeve 8 on the outer wall of the fixed shaft 7 is connected to the push plate 9 and the connecting rod 10, according to the transmission principle of the shaft and the fixed part, the fixed sleeve 8 will drive the push plate 9 and the connecting rod 10 to rotate synchronously. At this time, the push plate 9 stirs the micro powder in the feeding box 2 and causes a part of it to enter the sorting box 1 through the discharge port 11. When the connecting rod 10 rotates with the fixed shaft 7, it drives the scraper to slide along the inner wall of the feeding box 2. Through the elastic force of the spring 18, the first scraper 20 always adheres to the inner wall and scrapes off the micro powder adhering to the wall surface.
[0032] While the fixed shaft 7 rotates, it drives the transmission sleeve 13 and the stirring blade 14 connected to the transmission shaft 12 inside the sorting box 1 to rotate. The stirring blade 14 stirs the diamond micro powder entering the sorting box 1, further dispersing the micro powder and preventing it from agglomerating. The fixed rod 15 on each stirring blade 14 is connected to the second scraper 16. The second scraper 16 contacts the inner wall of the sorting box 1. When the stirring blade 14 rotates, it simultaneously scrapes off the powder adhering to the inner wall of the sorting box 1 to avoid residual particles affecting subsequent particle size detection.
[0033] 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.
