[0001] The invention relates to the technical field of diamond production, in particular to a diamond heating sleeve assembly and a processing device thereof. Background Art

[0002] The artificial synthesis of diamond usually adopts the high temperature and high pressure method, which needs to be carried out under very high temperature and pressure environment. Under such extreme conditions, the materials used must have excellent high temperature resistance, high pressure resistance and chemical stability.

[0003] In the process of diamond production, the diamond heating sleeve can ensure the temperature difference required for the synthesis of large single crystals, which is conducive to the stable and rapid growth of large single crystals.

When the ladder frame 21 moves, the inclined surface of the ladder frame 21 cooperates with the inclined groove 22 of the lifting plate 20 to lift the lifting plate 20.

[0041] The guide rod 23 guides the lifting and lowering of the lifting plate 20 to avoid deviation, and the first spring 24 is used for stable resetting.

[0042] In one embodiment, the feeding assembly includes an extrusion rod 11 and a trapezoidal rod 14, a feeding hole is opened on the upper surface of the feeding box 7, a box cover 12 is arranged at the feeding hole of the feeding box 7, a discharging hole is opened on the lower surface of the feeding box 7, two symmetrical inclined plates 16 are fixedly connected to the inner wall of the feeding box 7, an extrusion rod 11 is slidably connected through the upper surface of the feeding box 7, a vibration ring groove is opened at the discharging hole of the feeding box 7, a vibration ring 25 is slidably connected to the inner wall of the vibration ring groove, a screen 26 is arranged in the vibration ring 25, a second spring 27 is fixedly connected between the vibration ring 25 and the inner wall of the vibration ring groove, and a trapezoidal rod 14 is fixedly connected between the two fixed frames 4.

[0043] In the process of the feeding box 7 moving to the top of the assembly cylinder 17, the trapezoidal rod 14 cooperates with the extrusion rod 11, the trapezoidal rod 14 squeezes the extrusion rod 11, the extrusion rod 11 squeezes the screen 26, and the screen 26 squeezes the second spring 27. When the extrusion rod 11 passes over the trapezoidal rod 14, the extrusion rod 11 is no longer squeezed, and the second spring 27 is released, causing the screen 26 to vibrate, thereby preventing the talc powder from being blocked above the screen 26 and unable to fall to complete the feeding.

[0045] During the process of the feeding box 7 moving to the top of the assembly cylinder 17, the gear 34 cooperates with the rack 9 and rotates. The rotation of the gear 34 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the cam 33 to rotate. The rotation of the cam 33 squeezes the impact block 29, so that the impact block 29 hits the inclined plate 16, causing the inclined plate 16 to vibrate, thereby preventing the talc powder from adhering to the surface of the inclined plate 16 and preventing it from falling, thereby completing the feeding.

[0046] The above embodiment discloses a diamond heating sleeve assembly and a processing device thereof, and its specific working principle and process are as follows:

[0047] The thermal insulation liner layer can ensure the temperature difference required for synthesizing large single crystals, which is conducive to the stable and rapid growth of large single crystals. At the same time, it avoids temperature unevenness caused by material errors and reduces the diamond synthesis rate.

[0048] S1: first load the pyrophyllite powder into the loading box 7, start the second hydraulic cylinder 6, the second hydraulic cylinder 6 drives the loading box 7 to move above the assembly cylinder 17, at this time the discharge hole of the loading box 7 is aligned with the assembly cylinder 17, the pyrophyllite powder in the loading box 7 is poured into the assembly cylinder 17, and the loading is completed;

[0049] S2: Start the first hydraulic cylinder 5, which drives the extrusion die 15 to descend. When the extrusion die 15 descends into the assembly cylinder 17, the pyrophyllite powder is pressed.

[0050] S3: When the loading box 7 moves to the top of the assembly cylinder 17, the gear 34 cooperates with the rack 9 to rotate, the rotation of the gear 34 drives the rotating shaft 32 to rotate, the rotation of the rotating shaft 32 drives the cam 33 to rotate, the rotation of the cam 33 squeezes the impact block 29, so that the impact block 29 hits the inclined plate 16, causing the inclined plate 16 to vibrate, so as to prevent the pyrophyllite powder from adhering to the surface of the inclined plate 16 and failing to fall, and the loading is completed;

[0051] S4: During the process of the feeding box 7 moving to the top of the assembly cylinder 17, the trapezoidal rod 14 cooperates with the extrusion rod 11, the trapezoidal rod 14 squeezes the extrusion rod 11, the extrusion rod 11 squeezes the screen 26, and the screen 26 squeezes the second spring 27. When the extrusion rod 11 passes over the trapezoidal rod 14, the extrusion rod 11 is no longer squeezed, and the second spring 27 is released, so that the screen 26 vibrates, thereby preventing the pyrophyllite powder from being blocked above the screen 26 and unable to fall to complete the feeding;

[0052] S5: In the process of the loading box 7 moving to the top of the assembly cylinder 17, the loading box 7 drives the sliding rod 13 to move, and the sliding rod 13 drives the ladder frame 21 to move. When the ladder frame 21 moves, the inclined surface of the ladder frame 21 cooperates with the inclined groove 22 of the lifting plate 20 to lift the lifting plate 20, and the lifting plate 20 moves upward to drive the sliding cylinder 19 to move upward. The sliding cylinder 19 pushes the talc cylinder that has been pressed in the assembly cylinder 17 into the assembly cylinder 17.
