Description

Technical Field

[0001] The present invention relates to the technical field of cultured diamond processing, and in particular to an automatic cultured diamond sorting device. Background Art

[0002] Cultured diamonds, also known as laboratory synthetic diamonds or artificial diamonds, are grown in a laboratory environment through advanced scientific and technological processes. Its main component is carbon (C), which is exactly the same as the composition of natural diamonds. The growth environment of cultured diamonds completely restores the growth conditions of natural diamonds. Through technologies such as high temperature and high pressure (HPHT) or chemical vapor deposition (CVD), carbon elements are crystallized under specific conditions to form diamonds. In the production and processing of cultured diamonds, sorting is a key step to ensure product quality and subsequent processing efficiency. Traditional manual sorting methods are not only time-consuming and labor-intensive, but also easily affected by human factors, resulting in difficulty in improving sorting accuracy and efficiency. With the continuous advancement of automation technology, automatic sorting equipment has gradually been used in the sorting process of cultured diamonds, aiming to achieve efficient and accurate sorting operations;

[0003] Some of the existing automatic cultured diamond sorting equipment use screen vibration to sort cultured diamonds of different sizes. For example, according to the "automatic cultured diamond sorting equipment" provided by China Patent Authorization Announcement No. CN221335281U, the screen plate can be driven to continuously flip upward and reset through the cooperation of a motor, a cam, a roller, a wheel seat, a spring, a screen plate and a screen, and the screen can be driven to shake, so as to sort the diamond raw materials falling on the screen, and larger diamond particles can be collected through the first discharge port, and smaller diamond particles can be collected through the second discharge port.

[0004] However, there are still some challenges when using screens to sort cultured diamonds. First, due to the different sizes and shapes of cultured diamonds, some diamonds are easily stuck in the mesh of the screen during the sorting process, causing the screen to be blocked and affecting the sorting efficiency. Secondly, when irregularly shaped diamonds move in the chute of the screen and guide plate, they are difficult to slide smoothly due to the large friction, further reducing the sorting efficiency. In addition, long-term operation will cause stains to accumulate on the surface of the screen and chute, which not only affects the smooth sliding of diamonds, but may also cause equipment failure.

[0005] Therefore, the market urgently needs an automatic sorting equipment that can efficiently and accurately sort cultured diamonds while effectively solving problems such as blockage, uneven flushing and stain cleaning. Summary of the invention

A conveying channel is provided inside the movable seat 85, and is fixedly connected to the two groups of driving cleaning structures 86 through a hose.

[0032] Specifically, the PLC controls the operation of the entire device through the electrical box 2. When working, the PLC controls the electrical control of the vibration motor, and the vibration motor drives the inclined vibration plate 9 and the guide plate 7 to vibrate. The staff pours the cultured diamonds of different sizes from the discharge funnel 3 into the sorting machine body 1. The cultured diamonds of different sizes fall into the screen 91 and are displaced downward by vibration. The smaller cultured diamonds that are displaced pass through the mesh of the screen 91 and fall onto the chute 71 of the guide plate 7, while the cultured diamonds that do not pass through are displaced downward and fall onto the upper discharge plate 4 to be discharged from the sorting machine 1 for collection, while the small cultured diamonds that fall into the chute 71 of the guide plate 7 are moved downward with the vibration and fall onto the lower discharge plate 5 to be discharged from the sorting machine 1 for collection, thereby realizing automatic screening of cultured diamonds.

[0033] The length of the upper discharge plate 4 is twice that of the lower discharge plate 5 , and the extended edges of the upper discharge plate 4 and the lower discharge plate 5 can be placed with a matching collecting frame.

[0034] In this embodiment, the driving cleaning structure 86 includes two mounting seats 861 fixed on both sides of the moving seat 85, a cleaning plate 862 is connected to the rotating shaft between the two mounting seats 861, and a waterproof motor 865 is fixed on one of the mounting seats 861, the output shaft of the waterproof motor 865 passes through the mounting seat 861 and is connected to the rotating shaft of the cleaning plate 862, the cleaning plate 862 is hollow inside, and is connected to the conveying channel of the moving seat 85 through a hose, and a plurality of nozzles 864 are evenly fixed on the top of the cleaning plate 862 and are connected to the inside, limiters are fixed on the top of the two bearing seats 82, and the limiters, bearing seats 82 and waterproof motors 865 are respectively electrically controlled and connected to the PLC control box 2; limiters are installed on the two bearing seats 82 connected by the threaded rod 83, and when the moving seat 85 moves to the end of the threaded rod 83, the limiter detects a signal and sends it to the PCL control box, and the PLC control box 2 controls the high-pressure water pump 63 to stop working, and then controls the deceleration The motor 81 flips and drives the threaded rod 83 to rotate, thereby driving the moving seat 85 to return. During the return process, the PLC controls the two driving cleaning structures 86 to flip in a small range and keep them vertical with the moving seat 85. During the return process of the moving seat 85, the two driving cleaning structures 86 are respectively squeezed, contacted and rubbed with the screen 91 and the slide groove 71, so that the cultured diamonds that have not been flushed out of the screen 91 can be squeezed out, and the stains on the surface of the screen 91 and the slide groove 71 can be cleaned. After the moving seat 85 returns, it is sensed by another limiter. After detecting the return, the PLC controls the electrical box 2 to control the two waterproof motors 865 to drive the two cleaning plates 862 to return to a V shape, control the high-pressure water pump 63 to pump water, and then control the reduction motor 81 to rotate forward to drive the threaded rod 83 to drive the moving seat 85 to move for flushing. This reciprocating process fully realizes the blockage cleaning and driving the cultured diamond displacement and unloading in the cultured diamond sorting process, and can also realize the cleaning of the screen 91 and the guide plate 7 to keep them clean.

[0035] Specifically, the circulating water supply structure 6 conveys water to the movable seat 85 through the connecting hose 66, and is diverted to the two driving cleaning structures 86 through the conveying channel and the hose for spraying, so as to flush the cultivated diamonds on the screen 91 and the chute 71. The two driving cleaning structures 86 are initially in a V-shape inclined up and down. During the flushing process, the PLC controls the electrical box 2 to control the reduction motor 81 to work, and the reduction motor 81 drives the threaded rod 83 to rotate and transmit the threaded transmission with the movable seat 85, and cooperates with the guide rod 84 to make the movable seat 85 stably displaced inside the sorting body 1, so as to completely flush the screen 91 and the chute 71, and can flush out the cultivated diamonds stuck in the screen 91, and can also flush the cultivated diamonds in the screen 91 and the chute 71 downward, so that all the cultivated diamonds can slide out and be collected.

[0037] In this embodiment, the circulating water supply structure 6 includes a collecting pool 61 and a high-pressure water pump 63 fixed at the bottom of the sorting body 1. The filter box 62 is fixed on the inner side of the collecting pool 61, and the input end of the high-pressure water pump 63 is connected to a water pipe that passes through the collecting pool 61 and enters the inside of the filter box 62. The output end of the high-pressure water pump 63 is connected to a delivery pipe 64, which passes through the sorting body 1 and is fixedly connected to a diversion pipe 65. The diversion pipe 65 is fixed to the outside of the sorting body 1, and the diversion pipe 65 is fixedly connected to a connecting hose 66. The connecting hose 66 passes through the sorting body 1 and is fixedly connected to the water pipe connector 851.

[0038] Specifically, the collection pool 61 can collect the water that falls in through flushing, and the high-pressure water pump 63 extracts the water in the collection pool 61 and transports it to the diversion pipe 65 through the delivery pipe 64. The water in the diversion pipe 65 is transported to the auxiliary delivery and cleaning device through the connecting hose 66 for flushing.

[0039] The filter box 62 includes an outer frame, and a filter net and a filter cotton combination are fixed inside the outer frame. During the water extraction process, impurities in the water are filtered out by the filter net and the filter cotton combination, so that the extracted water is relatively clean.

[0040] The collecting pool 61 is fixedly connected with a drain pipe, which runs through the sorting machine body 1 and is equipped with a control valve. By opening the control valve, the water in the collecting pool 61 can be discharged.

[0041] Among them, the collecting pool 61 is fixedly connected to a water pipe, the water pipe runs through the sorting machine body 1 and is equipped with a control valve to connect with the external water pipe. A liquid level sensor can be installed in the collecting pool 1 and electrically connected to the PLC control box 2 for liquid level monitoring. When there is insufficient water in the collecting pool 1, the liquid level sensor sends information, the PLC control box 2 stops the high-pressure water pump 63, and manually opens the control valve to allow the external delivery pipe to infuse liquid into the collecting pool 1.

[0042] Embodiment 2, on the basis of embodiment 1, the driving cleaning structure 86 includes two mounting seats 861 fixed on both sides of the moving seat 85, a cleaning plate 862 is connected to the rotating shaft between the two mounting seats 861, and a waterproof motor 865 is fixed on one of the mounting seats 861, the output shaft of the waterproof motor 865 passes through the mounting seat 861 and is transmission-connected to the rotating shaft of the cleaning plate 862, the cleaning plate 862 is hollow inside, and is connected to the conveying channel of the moving seat 85 through a hose, and a plurality of nozzles 864 are evenly fixed on the top of the cleaning plate 862 and are connected to the inside, a hard brush plate 863 is fixed on one side of the top of the cleaning plate 862, and the hard brush plate 863 can contact the screen 91 or the slide groove 71 when the moving seat 85 is kept in a vertical state.

[0043] Specifically, the driving cleaning structure 86 delivers the water to the moving seat 85, and the water is diverted to the two driving cleaning structures 86 through the delivery channel and the hose. The initial state of the two driving cleaning structures 86 is a V-shaped shape that is inclined up and down. The multiple nozzles 864 on the two cleaning plates 862 are respectively directed to the screen 91 and the cleaning trough. The infusion is carried out inside the cleaning plate 862, and the high-pressure water is sprayed from the multiple nozzles 864 to flush the cultured diamonds on the screen 91 and the chute 71. When the moving seat 85 stably displaces inside the sorting body 1, the screen 91 and the chute 71 can be completely flushed, which can not only flush out the cultured diamonds stuck in the screen 91, but also flush the cultured diamonds in the screen 91 and the chute 71. The diamonds are displaced downward, so that all the cultured diamonds can slide out and be collected. During the process of driving the movable seat 85 to return, the PLC controls the electrical control of the waterproof motors 865 in the two driving cleaning structures 86 to work. The waterproof motors 865 drive the cleaning plates 862 to flip over in a small range, so that the two cleaning plates 862 and the movable seat 85 remain vertical. The two hard brush plates 863 on the upper and lower cleaning plates 862 are in contact with the screen 91 and the slide 71 respectively. During the process of the movable seat 85 returning, the two hard brush plates 863 are squeezed, contacted and rubbed with the screen 91 and the slide 71 respectively, so that the cultured diamonds that have not been flushed out of the screen 91 can be squeezed out, and the stains on the surface of the screen 91 and the slide 71 can be cleaned.

[0044] Working principle:

[0045] The whole device is controlled by the PLC control electric box 2. When working, the PLC controls the electrical control of the vibration motor, and the vibration motor drives the tilted vibration plate 9 and the guide plate 7 to vibrate. The staff pours the cultured diamonds of different sizes from the discharge funnel 3 into the sorting machine body 1. The cultured diamonds of different sizes fall into the screen 91 and move downward by vibration. The smaller cultured diamonds pass through the mesh of the screen 91 and fall into the chute 71 of the guide plate 7, while the cultured diamonds that do not pass through the screen move downward and fall onto the upper discharge plate 4 to be discharged from the sorting machine body 1 for collection. The small cultured diamonds that fall into the chute 71 of the guide plate 7 move downward with the vibration and fall onto the lower discharge plate 5 to be discharged from the sorting machine body 1 for collection, thereby realizing the automatic screening of cultured diamonds.

[0046] During the vibration process, some cultured diamonds are easily stuck in the mesh of the screen 91, and some cultured diamonds are irregular in shape and have large friction, making it difficult for them to move in the screen 91 and the guide plate 7 chute 71. At this time, the PLC controls the electrical box 2 to control the circulating water supply structure 6 and the auxiliary conveying and cleaning device 8 to work;

[0047] The high-pressure water pump 63 extracts water from the collection pool 61. During the water extraction process, the water is filtered through the filter box 62 to keep it clean. The high-pressure water pump 63 delivers the water to the shunt pipe 65 through the delivery pipe 64. The water in the shunt pipe 65 is delivered to the movable seat 85 through the connecting hose 66, and is shunted to the two driving cleaning structures 86 through the delivery channel and the hose. The two driving cleaning structures 86 are initially in a V-shape that is inclined up and down. The multiple nozzles 864 on the two cleaning plates 862 are respectively facing the screen 91 and the cleaning groove. The infusion is carried out inside the cleaning plate 862, and high-pressure water is sprayed from the multiple nozzles 864 to flush the culture on the screen 91 and the slide 71.

[0048] During the flushing process, the PLC controls the electric box 2 to control the reduction motor 81 to work, and the reduction motor 81 drives the threaded rod 83 to rotate and transmit the threaded transmission to the moving seat 85, and cooperates with the guide rod 84 to make the moving seat 85 stably displaced inside the sorting machine body 1, so as to completely flush the screen 91 and the chute 71, which can not only flush out the cultured diamonds stuck in the screen 91, but also flush the cultured diamonds in the screen 91 and the chute 71 downward, so that all the cultured diamonds can slide out and be collected; limiters are installed on the two bearing seats 82 connected to the threaded rod 83. When the moving seat 85 moves to the end of the threaded rod 83, the limiter detects a signal and sends it to the PCL control electric box. The PLC controls the electric box 2 to control the high-pressure water pump 63 to stop working, and then controls the reduction motor 81 to flip and drive the threaded rod 83 to rotate, thereby driving the moving seat 85 to return. During the return process, the PLC controls the electrical control of the waterproof motor 865 in the two driving cleaning structures 86 to work, and the waterproof motor 86 5 drives the cleaning plate 862 to flip over in a small range, so that the two cleaning plates 862 and the moving seat 85 remain vertical, and the two hard brush plates 863 on the upper and lower cleaning plates 862 contact the screen 91 and the slide 71 respectively. During the return process of the moving seat 85, the two hard brush plates 863 are squeezed, contacted and rubbed with the screen 91 and the slide 71 respectively, so that the cultured diamonds that have not been flushed out of the screen 91 can be squeezed out, and the stains on the surfaces of the screen 91 and the slide 71 can be cleaned. After the moving seat 85 returns to its position, it is sensed by another limiter. After detecting the return, the PLC controls the electric box 2 to control the two waterproof motors 865 to drive the two cleaning plates 862 to return to a V shape, control the high-pressure water pump 63 to pump water, and then control the reduction motor 81 to rotate forward to drive the threaded rod 83 to drive the moving seat 85 to move for washing. This reciprocating process fully realizes the blockage cleaning in the cultured diamond sorting process and drives the cultured diamond to move and discharge, and can also realize the cleaning of the screen 91 and the guide plate 7 to keep them clean.

[0049] During the flushing process, the flushed water falls into the chute 71 or falls into the collection pool 61 from the gaps on both sides, and most of the water in the chute 71 also slides down and falls into the collection pool 61 through the seepage net for collection. The collected water is re-extracted by the high-pressure water pump 63, thereby realizing the recycling of water resources and reducing waste.
