[0002] In the traditional process of crushing synthetic diamond semi-finished products, single-stage crushing is commonly used. However, single-stage crushing is inefficient and easily leads to large particle residues, requiring repeated crushing, which increases energy consumption. Moreover, synthetic diamond semi-finished products may vary in size, and when crushing these diamond semi-finished products of different sizes, especially large pieces, material jamming may occur. To address these issues, we have proposed a synthetic diamond semi-finished product crushing device. Utility Model Content

[0018] 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.
[0019] Please see Figures 1-3 In this implementation plan: a synthetic diamond semi-finished product crushing device; implementation method:
[0020] Overall structure of crushing box 1: The top of crushing box 1 is provided with a feed hopper 5 for feeding diamond semi-finished products to be crushed. The upper part of the interior is equipped with two first crushing rollers 12 and two second crushing rollers 13 for crushing the artificial diamond semi-finished products. The bottom is equipped with a discharge hopper 2 to facilitate the discharge of crushed materials.
[0021] Installation of the first crushing roller 12: In the upper part of the crushing box 1, two parallel first rotating shafts 14 are installed through bearing seats. The first crushing roller 12 is fixedly installed on the outer ring of each first rotating shaft 14. The surface of the first crushing roller 12 is covered with teeth for crushing, and these teeth are designed to be staggered to enhance the crushing effect.
[0022] Installation of the second crushing roller 13: In the lower part of the crushing box 1, two parallel second rotating shafts 15 are also installed through bearing seats. The second crushing roller 13 is fixedly installed on the outer ring of the second rotating shaft 15, and the teeth on its surface are also staggered to form an effective crushing mechanism.
[0023] Setting of moving block 6 and spring 7: Through holes are opened on both sides of the upper part of the crushing box 1, and moving blocks 6 are slidably installed in the through holes. Each moving block 6 has a hole in the middle so that the two ends of the first rotating shaft 14 on the front can pass through and be rotatably connected to it through bearings. In order to provide an automatic adjustment function, a spring 7 is fixedly installed on the inner wall of one side of the through hole, and the other end of the spring 7 is fixedly connected to one side of the moving block 6. In this way, when the material passes through, the gap between the crushing rollers can be automatically adjusted according to the thickness of the material.
[0024] Installation of guide rail 11: In order to make the moving block 6 slide smoothly in the through hole, guide rail 11 is installed on the top and bottom inner walls of the through hole. Slide grooves matching the guide rail 11 are opened on the top and bottom of the moving block 6 to facilitate the movement of the moving block 6.
[0025] Drive unit configuration: A support plate 3 is welded to the left side of the crushing box 1. The top of the support plate 3 is fixedly installed with a drive motor 4 by bolts. The output shaft of the drive motor 4 is connected to one end of the first rotating shaft 14 near the back side by a coupling or direct connection to provide power for the entire crushing system.
[0026] Synchronization and transmission mechanism: Synchronous pulleys are respectively installed at one end of the first rotating shaft 14 and the second rotating shaft 15 near the back, and they are connected by a synchronous belt 8. When the first rotating shaft 14 rotates, it can drive the second rotating shaft 15 to rotate. At the same time, the two second rotating shafts 15 are equipped with meshing gears 9 at one end outside the crushing box 1, so that the two second rotating shafts 15 can rotate at the same time.
[0027] Support structure: Support legs 10 are installed at the four corners of the bottom of the crushing box 1 to make the whole device stable.
[0028] The working principle and usage process of this utility model: When the power is turned on, the drive motor 4 is started. The drive motor 4 drives the first rotating shaft 14 near the back to rotate. Through the transmission of the synchronous belt 8 and the gear 9, the second rotating shaft 15 near the back and the second crushing roller 13 on it also rotate, which can crush the artificial diamond semi-finished products that enter the crushing box 1.
[0029] Material crushing: The semi-finished synthetic diamond is fed into the crushing box 1 through the feed hopper 5. The material first comes into contact with and is subjected to the squeezing and shearing action of the first crushing roller 12. Due to the staggered arrangement of the teeth of the first crushing roller 12 and the second crushing roller 13, and the fact that the second crushing roller 13 is located below the first crushing roller 12, multi-stage and effective crushing of the semi-finished synthetic diamond can be achieved.
[0030] Discharge and adjustment: During the crushing process, if the material thickness changes, the moving block 6 will automatically adjust its position under the action of the spring 7, thereby changing the gap between the two sets of first crushing rollers 12 to adapt to materials of different sizes, avoid material jamming, and improve crushing efficiency and effect. The crushed material is discharged through the discharge hopper 2.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
