Abstract
Description
Technical Field
[0001] This utility model relates to the field of synthetic diamond processing, and in particular to a synthetic diamond screening machine. Background Technology
[0002] A synthetic diamond sorting machine is an automated or semi-automated grading device for synthetic diamond particles. By integrating a feeding system, a core sorting module, a discharge collection system, and a control system, it uses sieving, optical imaging, density sorting, and other technologies to accurately separate diamond particles of different qualities and specifications based on the physical or chemical properties of diamond, such as particle size, density, defects, and purity. This process eliminates substandard products, achieves quality-based grading and specification matching, and ultimately meets the differentiated diamond needs of various downstream industries such as abrasives, cutting tools, and jewelry. It is a key piece of equipment for ensuring product consistency and application adaptability.
[0003] In the prior art, a Chinese utility model with publication number CN221537277U discloses a synthetic diamond screening machine, which screens diamonds by adjusting the internal sieve plates of different sizes. However, during the operation of such equipment, it was found that because diamonds are irregularly shaped and have different edges and corners on their surfaces, they often get stuck on the sieve. Simply using vibration or other methods cannot solve the problem of getting stuck in a timely and effective manner. Furthermore, because the diamonds cover a wide range of sizes, frequently changing the sieves of different sizes also affects the processing efficiency. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings:
[0032] like Figures 1-9 As shown, a synthetic diamond screening machine includes a switching mechanism 3 for screening diamonds of different sizes and a turning mechanism 4 for assisting the switching mechanism 3 in turning the diamonds to improve the screening effect. The switching mechanism 3 is installed inside the protective mechanism 2. A support mechanism 1 is provided at the bottom of the protective mechanism 2. The turning mechanism 4 is installed at the upper end of the switching mechanism 3 and located inside the protective mechanism 2. A central oscillation mechanism 6 for driving the switching mechanism 3 to oscillate is installed at the bottom of the switching mechanism 3.
[0033] The switching mechanism 3 includes a bottom drain plate 31, and the bottom drain plate 31 and the top drain plate 32 are stacked and arranged, with the top drain plate 32 located on the top of the bottom drain plate 31. The bottom drain plate 31 and the top drain plate 32 are connected through the power shaft 52 of the power mechanism 5 at their axial center positions. The top drain plate 32 is snapped into the protective cylinder 21 of the protective mechanism 2. The bottom drain hole 311 of the bottom drain plate 31 and the top drain hole 321 of the top drain plate 32 have the same diameter. A lever 33 is fixedly connected to the front end of the bottom drain plate 31. The lever 33 extends out of the protective cylinder 21 and is connected to the ear plate of the protective cylinder 21 by bolts.
[0034] The actuating mechanism 4 includes a fixed sleeve 41, which is sleeved on the power shaft 52 and located at the upper end of the top perforated plate 32. Several mounting rods 42 are evenly arranged on the outer circular end face of the fixed sleeve 41. Several actuating brushes 43 are installed at an angle at the bottom of the mounting rods 42. The actuating brushes 43 are installed on the mounting rods 42 through the cooperation of the rotating shaft 44 and the torque member 45.
[0035] In this embodiment, the rotating shaft 44 is formed with the agitator brush 43, and the rotating shaft 44 is externally sleeved with a torque member 45. The two ends of the torque member 45 are respectively fixed to the rotating shaft 44 and the mounting rod 42. By utilizing the cooperation between the rotating shaft 44 and the torque member 45, the agitator brush 43 can rotate when it is agitated, thereby improving the disorder of agitation of the bottom diamond.
[0036] In this embodiment, the central oscillation mechanism 6 includes a rotating disk 61, which is keyed to the power shaft 52. A vertical disk 62 is provided at the upper end of the rotating disk 61. An oscillation sleeve 63 is provided on both the top surface of the rotating disk 61 and the bottom surface of the vertical disk 62. An oscillation sleeve 63 is provided at the top of the vertical disk 62. The oscillation sleeve 63 is rotatably connected to the outside of the power shaft 52. The oscillation sleeve 63 is slidably connected to the protective cylinder 21 through a spline. The top surface of the oscillation sleeve 63 cooperates with the bottom of the bottom perforated plate 31. The oscillation transmitted upward by the oscillation sleeve 63 provides central oscillation for the bottom perforated plate 31 and the top perforated plate 32. The oscillation is diffused outward through the circular bottom perforated plate 31 and the top perforated plate 32, thereby improving the effect of oscillation kinetic energy.
[0037] In this embodiment, four mounting rods 42 are provided, and the mounting rods 42 have an arc-shaped structure. The arc-shaped structure can be used to move the outer diamond towards the center side when rotating and turning.
[0038] In this embodiment, the agitator brush 43 is mounted at an angle on the bottom surface of the mounting rod 42.
[0039] In this embodiment, the bristles at the bottom of the agitator brush 43 are divided into inner and outer layers, and the hardness of the inner bristles is greater than that of the outer bristles. The inner bristles are harder, which can help the diamond to disengage from the stuck position when it encounters a stuck diamond, in conjunction with the hard bristles and the rotating agitator brush 43.
[0040] In this embodiment, the bottom sprue plate 31 is rotatably connected to the protective cylinder 21, and scale lines are formed on both the lever 33 and the ear plate. The ear plate is formed with an arc-shaped groove for the mating bolt.
[0041] Working principle: When screening is required, the motor inside the support mechanism 1 (not shown) drives the power shaft 52 to rotate through the reducer 51. The power shaft 52 drives the rotating disk 61 and the top fixed sleeve 41 to rotate.
[0042] Furthermore, adjust the rotation angle of the top strainer 32 according to the required screening size, so that the bottom strainer holes 311 and 312 on the bottom strainer 31 and the top strainer 32 overlap. Figure 8 As shown, at this time, the rotating disk 61 continuously cooperates with the protrusion 64 on the vertical disk 62 through the top protrusion 64, so that the vertical disk 62 and the oscillating sleeve 63 transmit the up and down oscillation to the bottom of the top slug plate 32, so that the top slug plate 32 and the bottom slug plate 31 generate oscillations that spread outward from the center. At the same time, the top fixing sleeve 41 drives the mounting rod 42 and the agitating brush 43 to start rotating. The agitating brush 43 agitates and rotates the diamonds. Diamonds of the correct size fall from the gap between the bottom slug hole 311 and the top slug hole 321 and are collected from the discharge hopper 22.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
