Description

Technical Field

[0001] This utility model relates to the field of gemstone color and clarity sorting machines, and more particularly to a portable gemstone color and clarity sorting machine. Background Technology

[0002] In the gemstone processing industry, color is one of the key factors determining the quality and value of a gemstone. Therefore, accurate color sorting of gemstones is crucial. Currently, existing color and clarity sorting machines on the market exhibit several problems that urgently need to be addressed when sorting gemstones by color.

[0003] From the perspective of sorting efficiency, existing color and clarity sorting machines have cumbersome workflows and limited processing speeds, making it difficult to meet the high-efficiency production needs of large-scale gemstone processing enterprises. This not only leads to longer production cycles but also significantly increases production costs. In terms of operation, these color and clarity sorting machines have complex interfaces and numerous parameter settings, requiring professional operators to spend a significant amount of time on debugging and operation. This undoubtedly increases labor costs and also raises the risk of human error.

[0004] More importantly, existing color and clarity sorting machines suffer from severe deficiencies in sorting accuracy. On the one hand, they are prone to missorting, wrongly classifying gemstones with acceptable color as unacceptable, or mixing unacceptable gemstones with acceptable ones, which greatly affects the quality stability of gemstone products. On the other hand, when faced with gemstones with similar colors, existing color and clarity sorting machines, due to their large color sorting range and lack of fine differentiation capabilities, cannot accurately identify and sort them, thus failing to fully explore the potential value of gemstones.

[0005] In conclusion, there is an urgent need to develop a gemstone color and clarity sorting machine that can overcome the above-mentioned shortcomings and achieve high efficiency, accuracy and ease of operation, which is of great significance for promoting the development of the gemstone processing industry. Utility Model Content

[0006] The technical problem this invention aims to solve is that existing color and clarity sorting machines have cumbersome workflows and limited processing speeds, making it difficult to meet the high-efficiency production needs of large-scale gemstone processing enterprises; at the same time, their sorting accuracy is also insufficient, easily leading to missorting and affecting the stability of gemstone sorting. To address the above-mentioned shortcomings of the prior art, this invention provides a portable gemstone color and clarity sorting machine.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A portable gemstone color and clarity sorting machine is constructed, including a sheet metal frame, a vibratory feeder mounted on the sheet metal frame, and a feeding assembly connected to the vibratory feeder. The sheet metal frame is equipped with a vibrating body that causes the vibratory feeder and the feeding assembly to vibrate. The feeding assembly is equipped with a slotted track. Gemstones to be sorted in the vibratory feeder enter the slotted track under vibration and move forward within the slotted track. Multiple sorting ports are provided on the side of the slotted track, and a first material box is provided at each sorting port. The color and clarity sorting machine also includes a detection component and a driving component corresponding to the sorting ports. The detection component detects the gemstones to be sorted in the slotted track, and the driving component drives the gemstones that meet the sorting conditions to enter the sorting ports.

[0009] Preferably, the detection component includes an optical fiber and a mounting bracket for fixing the light, and also includes an amplifier. After the amplifier sets the sorting conditions, the optical fiber detects the gemstone to be sorted. If the gemstone meets the sorting conditions, the drive component will drive the gemstone to be sorted into the sorting port.

[0010] Preferably, the amplifier further includes an amplifier protective cover, and a focusing lens is provided at the end of the light beam. The focusing lens focuses the light emitted by the light beam into a spot, and the light beam can rotate or slide relative to the mounting bracket.

[0011] Preferably, the mounting bracket further includes a rotating arm connected to the optical fiber, a connecting arm connected to the rotating arm, and a sliding arm connected to the connecting arm. The rotating arm can rotate on the connecting arm to drive the optical fiber to rotate, and the connecting arm can slide on the sliding arm to drive the optical fiber to slide.

[0012] Preferably, the driving component includes an air nozzle and an air pump connected to the air nozzle, and also includes a solenoid valve corresponding to the detection component. When the detection component detects that the sorting conditions are met, the solenoid valve actuates to cause the air nozzle to blow air and blow the gemstone into the sorting port.

[0013] Preferably, a throttle valve and a gas filter are provided between the air nozzle and the air pump, a self-locking button is provided on the sheet metal frame, and the air nozzle is an eccentric air nozzle.

[0014] Preferably, the feeding component is provided with an air blowing hole corresponding to the driving component, the driving component provides driving force to the gemstone at the air blowing hole, and a second material box is provided at the end of the slotted track.

[0015] Preferably, the sorting port is inclined and funnel-shaped.

[0016] Preferably, the sheet metal frame is provided with handles on both sides and a foot cup at the bottom of the sheet metal frame, the height of which is adjustable.

[0017] The beneficial effects of this invention are as follows: The color of the gemstone is detected by the detection component. If it falls within the color range of the current amplifier, the solenoid valve and air nozzle activate to blow the gemstone towards the corresponding sorting port, where it falls into the corresponding material box. This makes the sorting process easier to operate and more efficient. The detection process uses optical fibers and a focusing lens for more accurate detection. Furthermore, the sorting range can be arbitrarily allocated and set in conjunction with the amplifier's parameter settings, making operation more convenient. The detection component can also rotate and slide to adjust its angle and extension distance, making it suitable for different scenarios. Multiple sorting ports can be set on the feeding component to meet various sorting needs. The sorting ports are designed in an inclined trumpet shape, facilitating the entry of gemstones from the slotted track and ensuring they fall into the material box. The air nozzle is equipped with a filtered gas and a throttle valve to control the flow rate and purity of the gas, ensuring that gemstones of different sizes can effectively enter the sorting port. This makes the equipment more powerful, more efficient, and easier to operate. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] A preferred embodiment of this utility model is a portable gemstone color and clarity selection machine; such as... Figures 1-2 As shown, the system includes a sheet metal frame 10, a vibratory feeder 11 mounted on the sheet metal frame, and a feeding assembly 21 connected to the vibratory feeder. The feeding assembly is equipped with a slotted track 210, and multiple sorting ports 211 are provided on the side of the slotted track. A first material box 14 and a second material box 15 are provided corresponding to each sorting port. The sheet metal frame is also equipped with a drive assembly 13 and a detection assembly 12 corresponding to the drive assembly. The gemstones to be sorted are placed in the vibratory feeder 11, and the drive device provides forward propulsion by direct vibration, causing them to be neatly arranged and continuously enter the slotted track 210 and move forward. At the same time, the slotted track also conveys the products forward under the continuous vibration. When passing through different sorting ports, the detection assembly detects the gemstones. If the current gemstone is found to meet the requirements, the drive assembly 13 drives the gemstone into the current sorting port and into the corresponding first material box 14, while unsorted gemstones enter the second material box 15. The sheet metal bracket 10 has four sets of foot cups 20 at its lower end. These foot cups are retractable to adjust their height, facilitating leveling and stable placement of the color and clarity sorting machine. Two sets of handles 19 are also located on the side of the sheet metal bracket, allowing for easy movement of the color and clarity sorting machine. An aviation connector is located on the back of the color and clarity sorting machine, providing access to the main power supply. A power switch 18 is also installed on the machine to control the main power supply.

[0027] Specifically, such as Figures 1-4As shown, the detection component 12 includes a mounting bracket 125 and an optical fiber 120 mounted on the mounting bracket. A focusing lens 121 is positioned below the optical fiber, focusing the light emitted from the optical fiber into a spot for detecting the color of the gemstone. To facilitate the installation and angle adjustment of the optical fiber, the mounting bracket 125 is equipped with a sliding arm 124 and a rotating arm 122 connected to the sliding arm. The sliding arm and the rotating arm are connected by a connecting arm 123. The optical fiber is fixed on the rotating arm. Since the rotating arm can rotate on the sliding arm, the rotation adjustment of the optical fiber can be achieved. Furthermore, the connecting arm can slide on the sliding arm to change the extension distance of the optical fiber, preferably at the intersection of the light-reversing sorting port and the slotted track. Simultaneously, to improve the detection effect of the detection component, an amplifier 16 connected to the detection component is also mounted on the sheet metal bracket. The amplifier is equipped with an amplifier protective cover 160. The amplifier amplifies the detection results of the optical fiber, facilitating the observation of the detection results. The amplifier has different parameter ranges set according to different gemstone colors. When a gemstone passes through different focusing lens positions on the slotted track, the displayed color value is also different. When a value within the range is detected, the drive assembly blows the gemstone towards the corresponding sorting port and into the corresponding first hopper 14, thus completing the sorting of gemstones within that value range. It can also be used to detect the shape, transparency, or other parameters related to the physical properties of gemstones.

[0028] Furthermore, such as Figures 1-2 and Figure 5 As shown, the drive assembly 13 includes an air nozzle 130. An air pump corresponding to the air nozzle is mounted on a sheet metal bracket. The air pump supplies gas to the drive assembly, and a gas filter connects the air nozzle and the air pump to filter the gas and prevent the gas generated by the air pump from blowing directly onto the gemstone and affecting it. The drive assembly also includes a solenoid valve mounting bracket 133, and a solenoid valve 132 and a throttle valve 131 mounted on the bracket. The solenoid valve controls the airflow channel, while the throttle valve controls the airflow magnitude. When the detection assembly detects that the current gemstone belongs to the corresponding range, it controls the solenoid valve to activate the drive assembly, blowing the gemstone towards the corresponding sorting port. For example, when detecting the size of the gemstone, the airflow magnitude can be controlled to control the blowing force. A self-locking button 17 is also provided on the sheet metal frame to control the air pump, preventing the air pump from being unable to shut off in case of malfunction and improving safety.

[0029] Furthermore, such as Figures 1-2 and Figure 6As shown, the feeding assembly 21 is mounted on the sheet metal frame via a connecting base 213. The feeding assembly has a slotted track 210, with multiple sorting ports 211 on one side. A first material box 14 is placed below each sorting port, and an air blowing hole 212 is provided on the other side of the slotted track corresponding to each sorting port. The air blowing nozzle of the drive assembly is placed at the air blowing hole. A second material box 15 is placed at the end 214 of the slotted track. This allows for the sorting of gemstones at different sorting ports by setting different parameters of the detection components. A material box support frame 24 can be installed below the first and second material boxes 14 to increase the height of the material boxes. To facilitate the entry of gemstones from the sorting ports into the material boxes, the sorting ports are inclined. After the drive assembly blows the gemstones towards the sorting ports, the gemstones can enter the material boxes by gravity and direct vibration. The sorting ports can also be funnel-shaped to facilitate the entry of gemstones from the slotted track.

[0030] When using the color and clarity sorting machine of this application, first move the machine to a suitable position using handle 19, then adjust the foot cup 20 to ensure stability, and adjust the mounting bracket 125 so that the focusing lens 121 is aligned with the intersection of the sorting port 211 and the slotted track 210. After connecting to mains power via aviation connector 22, press the power switch 18 to start the color and clarity sorting machine. Set the corresponding parameter range of the amplifier 16 according to each sorting port 211, place the gemstone to be sorted in the vibratory feeder 11, and the controller controls the vibrator to vibrate vertically, causing the vibratory feeder 11 and the feeding assembly 21 to vibrate. During vertical vibration, the vibratory feeder 11 transports the gemstone to be sorted into the slotted track 210. Due to the vertical vibration, the gemstone moves forward sequentially within the slotted track. When it reaches the sorting port 211, the light emitted by the optical fiber is focused into a spot by the focusing lens to detect the current color range of the gemstone. If the color range falls within the current amplifier's value range, the solenoid valve is activated to blow... Gas is blown out of nozzle 130 to blow the gemstone toward the corresponding sorting port. After moving within the sorting port, the gemstone falls into the corresponding first material box 14, thus completing the sorting of the current gemstone. If the detected color range is not within the current amplifier's value range, the solenoid valve does not activate, and the gemstone continues to move to the next sorting port for detection and judgment. If it is within the current value range, the solenoid valve activates. This process is repeated through all sorting ports. If the gemstone still does not meet the requirements, it will fall into the second material box, and the gemstone sorting is completed. The sorting speed is faster, the efficiency is higher, and the operation is simpler. The sorting machine occupies less space and can be used to sort diamonds, rubies, sapphires of various colors, as well as natural gemstones or various artificial gemstones.

[0031] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
