Description

Technical Field

[0001] The utility model relates to the technical field of diamond processing, in particular to a diamond sorting machine. Background Art

[0002] Due to its unique hardness and beautiful refractive properties, diamond is widely used in gemstone jewelry and industrial equipment. Diamond sorting is an essential step in diamond manufacturing. At a specific vibration frequency, diamonds with different crystal shapes have different movement trajectories on an inclined plane at a certain inclination angle. The sorting machine utilizes this characteristic to sort diamonds of different crystal forms, and then subsequent processing steps are carried out. The sorting machine generally includes a sorting disk, a vibration motor, and several collection boxes. The sorting disk is inclined; the vibration motor provides a vibration source for the sorting disk; the collection boxes are arranged side by side and are placed at the bottom of the slope of the sorting disk.

[0003] During the sorting process, the inclination angle and vibration frequency of the sorting disk of the sorting machine are determined by the ideal working conditions, that is, the crystal size is appropriate and there is no adhesion between crystals. However, in the actual production process, due to mechanical failures, power fluctuations, etc., the frequency of the vibration motor deviates from the set frequency, or the humidity of the diamonds to be sorted is too high, etc. These will greatly affect the sorting effect. At present, there are few treatment methods for such abnormal states. Workers need to be arranged to check the effect after sorting during production. If the effect is not good, re-sorting is required, resulting in low efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a diamond sorting machine, which can stop running in time when the humidity of the diamond is too high and block the diamonds currently in the sorting disk from falling into the collection box.

[0005] To achieve the above object, the utility model discloses a diamond sorting machine, which includes an installation platform, an inclined sorting disk, a vibration motor that provides a vibration source for the sorting disk, and several collection boxes. The sorting disk is erected on the installation platform. A collection station is arranged at a position of the installation platform close to the discharge end of the sorting disk. The collection boxes are arranged side by side at the collection station. In addition, it further includes a controller, a humidity sensor, a feeding mechanism, and an avoidance mechanism. The feeding mechanism is used to feed the diamonds to be sorted onto the sorting disk; the humidity sensor is arranged inside the feeding mechanism, or at the discharge end of the feeding mechanism, or at the feeding end of the sorting disk; an aggregate trough is arranged at the collection station, and the collection boxes are placed above the aggregate trough and block the aggregate trough; the avoidance mechanism can drive all the collection boxes to synchronously move away from the sorting disk; the vibration motor, the humidity sensor, the feeding mechanism, and the avoidance mechanism are all connected to the controller.

[0006] With the above settings, the humidity sensor detects the humidity of the diamonds to be sorted and feeds back to the controller. When the controller determines that the humidity of the diamonds is greater than the set value, the controller immediately controls the feeding mechanism to stop feeding the sorting tray, and at the same time controls the avoidance mechanism to act, pushing the collection box away from the sorting tray to prevent the unqualified diamonds from falling into the collection box. After the collection box is pushed away, the aggregate chute will be exposed, and the diamonds in the sorting tray will fall into the aggregate chute for collection and then return to the feeding mechanism. After processing the diamonds to be sorted, that is, when the humidity of the diamonds to be sorted meets the sorting requirements, the avoidance mechanism then resets the collection box. After the vibration motor starts and stabilizes, the feeding mechanism can continue to feed the sorting tray to perform the sorting work.

[0007] Preferably, it further includes a base, the base is slidably connected to the installation platform, the collection box is placed on the base, and the avoidance mechanism drives the base away from the sorting tray. By providing the base, it can ensure the synchronous movement of all collection boxes and is also conducive to the placement of the collection box.

[0008] Preferably, three baffles are provided on the outer periphery of the aggregate chute, and a retaining wall is provided at one end of the base close to the sorting tray. The three baffles and the retaining wall can cooperate to enclose a guiding space for guiding the diamonds into the aggregate chute. By providing the guiding space, it is conducive to the collection of diamonds, avoiding falling elsewhere and causing waste. A part of the guiding space is provided by the retaining wall on the base, and the guiding space will not interfere with the normal use of the collection box.

[0009] Preferably, a first slope is provided at the bottom of the base, and a second slope adapted to the first slope is provided on the installation platform. The base is slidably connected to the second slope through the first slope; when the avoidance mechanism drives the base away from the sorting tray, the base moves towards the top of the second slope. With such a setting, the collection box can be lifted to a certain extent when it moves away from the sorting tray. In this way, even if the horizontal displacement distance of the collection box when moving away from the sorting tray is shorter, it can still prevent the unqualified diamonds from falling into the collection box, and at the same time is also conducive to the setting of the avoidance mechanism.

[0010] Preferably, first sliding rods and second sliding rods are provided on both sides of the base. The first sliding rods are arranged at one end of the base close to the sorting disc, and the second sliding rods are arranged at one end of the base far from the sorting disc. First sliding channels and second sliding channels are provided on the mounting platform. The first sliding rods are inserted into the first sliding channels and are slidably connected thereto. The second sliding rods are inserted into the second sliding channels and are slidably connected thereto. The first sliding channels are inclined, and the second sliding channels are horizontal. When the avoidance mechanism drives the base away from the sorting disc, the first sliding rods move towards the higher positions of the first sliding channels. After such an arrangement, when the collection box moves away from the sorting disc, one end of the collection box close to the sorting disc can be lifted to a certain extent. In this way, even if the horizontal displacement distance of the collection box away from the sorting disc is shorter, it can still prevent unqualified diamonds from falling into the collection box during sorting, and at the same time, it is also beneficial to the arrangement of the avoidance mechanism.

[0011] Preferably, the avoidance mechanism includes at least one electromagnet and at least one elastic member. One end of the elastic member is connected to the mounting platform, and the other end of the elastic member is connected to the base. The electromagnet is arranged on the side of the base far from the sorting disc. A magnetic attraction member magnetically matched with the electromagnet is provided on the base, or the base is made of a magnetic attraction material.

[0012] Alternatively, the avoidance mechanism is a cylinder.

[0013] Through the above arrangements, when the humidity of the diamonds to be sorted does not meet the standard, the diamonds currently in the sorting disc can be quickly and stably blocked from falling into the collection box. By adopting the cooperation mode of magnetic attraction and elastic members, the action can be relatively gentle to avoid the diamonds in the collection box from being jolted out, while adopting a cylinder can ensure the rapidity of the action.

[0014] Preferably, the length of the aggregate trough is not less than the width of the outlet end of the sorting disc. Such an arrangement can ensure that the diamonds in the sorting disc smoothly fall into the aggregate trough.

[0015] Preferably, a material guiding channel and a waste box are further provided on the mounting platform. The waste box is placed or detachably connected below the mounting platform. The upper channel opening of the material guiding channel is adapted to the size of the aggregate trough, and the upper channel opening of the material guiding channel is communicated with the aggregate trough, and the lower channel opening of the material guiding channel is communicated with the waste box. After such an arrangement, the diamonds in the aggregate trough can be gathered into the waste box, which is convenient for returning this part of the diamonds to the feeding mechanism.

[0016] Preferably, a heater and / or a fan is provided in the feeding mechanism. The heater and the fan are connected to a controller. By providing the heater and / or the fan, heating and / or ventilation can be carried out when the feeding mechanism stops feeding, thereby adjusting the humidity of the diamonds to be sorted.

[0017] Preferably, it further includes a detection component for detecting the voltage, rotation speed, and frequency of the vibration motor, and the detection component is connected to the controller. By setting the detection component, it is possible to stop feeding the sorting tray in a timely manner when the sorting tray vibrates abnormally, and timely block the diamond currently in the sorting tray from falling into the collection box, further ensuring the sorting effect.

[0018] The utility model has the following beneficial effects:

[0019] The utility model detects the humidity of the diamond to be sorted through a humidity sensor and feeds it back to the controller. When the controller determines that the humidity of the diamond is greater than the set value, the controller immediately controls the feeding mechanism to stop feeding the sorting tray, and at the same time controls the avoidance mechanism to act, pushing the collection box away from the sorting tray to prevent the unqualified diamond from falling into the collection box. After the collection box is pushed away, the aggregate chute will be exposed, and the diamond in the sorting tray will fall into the aggregate chute for collection, and then return to the feeding mechanism. After processing the diamond to be sorted, that is, when the humidity of the diamond to be sorted meets the sorting requirements, the avoidance mechanism makes the collection box reset. After the vibration motor starts stably, the feeding mechanism can continue to feed the sorting tray to perform the sorting work. Description of the Drawings

[0036] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Embodiment 1

[0038] As Figures 1 to 4 shown, this embodiment discloses a diamond selection machine, which includes an installation platform 10, an inclined sorting disc 30, a vibration motor 31 (which can be arranged at the bottom of the sorting disc 30) providing a vibration source for the sorting disc 30, a controller, a humidity sensor 41, a feeding mechanism 40, an avoidance mechanism, and a number of collection boxes 50. The sorting disc 30 and the feeding mechanism 40 are both mounted on the installation platform 10. The feeding mechanism 40 is used to feed the diamonds to be sorted onto the sorting disc 30. The feeding mechanism 40 can be a funnel with an electric valve, or the feeding mechanism 40 can be a screw feeder. The feeding mechanism 40 is connected to the controller, and the controller controls the feeding process. The humidity sensor 41 is arranged inside the feeding mechanism 40 or at the discharge end of the feeding mechanism 40 or the feeding end of the sorting disc 30, and is used for the humidity of the diamonds fed onto the sorting disc 30. The humidity sensor 41 is connected to the controller. In addition, a heater and / or a fan can be arranged in the feeding mechanism 40. The heater and the fan are connected to the controller. By arranging the heater and / or the fan, heating and / or ventilation can be carried out when the feeding mechanism 40 stops feeding, so as to adjust the humidity of the diamonds to be sorted.

[0039] A collection station is provided at a position on the installation platform 10 close to the discharge end of the sorting tray 30. Under normal conditions, the collection boxes 50 are arranged side by side at the collection station, and the diamonds sorted by the sorting tray 30 fall into the respective collection boxes 50. To facilitate the placement and movement of the collection boxes 50, a base 20 is provided, and the collection boxes 50 are placed on the base 20. An aggregate trough 11 is provided at the collection station. Under normal conditions, the collection boxes 50 block the aggregate trough 11. When all or part of the collection boxes 50 leave the collection station, the diamonds in the sorting tray 30 will all fall into the aggregate trough 11. The length of the aggregate trough 11 is not less than the width of the outlet end of the sorting tray 30 to ensure that the diamonds in the sorting tray 30 smoothly fall into the aggregate trough 11.

[0040] To further ensure that the diamonds in the sorting tray 30 smoothly fall into the aggregate trough 11, three baffle plates 12 are provided on the outer periphery of the aggregate trough 11, and a retaining wall 21 is provided at one end of the base 20 close to the sorting tray 30. The three baffle plates 12 and the retaining wall 21 can cooperate to enclose a guiding space for guiding the diamonds into the aggregate trough 11. By providing the guiding space, it is beneficial to collect the diamonds and avoid wasting them by falling elsewhere. A part of the guiding space is provided by the retaining wall 21 on the base 20, and the guiding space will not interfere with the normal use of the collection boxes 50.

[0041] To facilitate the gathering of the diamonds in the aggregate trough 11, a material guiding channel 13 and a waste box 14 are further provided in the installation platform 10. The waste box 14 is placed or detachably connected below the installation platform 10. The upper channel opening of the material guiding channel 13 is adapted to the size of the aggregate trough 11, and the upper channel opening of the material guiding channel 13 is communicated with the aggregate trough 11, while the lower channel opening of the material guiding channel 13 is communicated with the waste box 14.

[0042] The avoidance mechanism is used to drive all the collection boxes 50 to synchronously move away from the sorting tray 30. Specifically, the avoidance mechanism includes at least one electromagnet 61 and at least one elastic member 62. The elastic member 62 can be a spring. One end of the elastic member 62 is connected to the installation platform 10 (baffle plate 12), and the other end of the elastic member 62 is connected to the base 20 (connection column 22 on the side of the base 20). The electromagnet 61 is provided on the side of the base 20 away from the sorting tray 30. A magnetic member magnetically coupled with the electromagnet 61 is provided on the base 20, or the base 20 is made of a magnetic material. The electromagnet 61 is connected to a controller. After the electromagnet 61 is energized, the magnetic force between it and the magnetic member or the base 20 overcomes the elastic force of the elastic member 62, and the base 20 moves towards the electromagnet 61, and the aggregate trough 11 is exposed, and at the same time, the guiding space is formed. When the electromagnet 61 is powered off, under the action of the elastic force of the elastic member 62, the collection boxes 50 are reset.

[0043] The working principle of this embodiment is as follows: The humidity sensor 41 detects the humidity of the diamonds to be sorted and feeds back to the controller. When the controller determines that the humidity of the diamonds is greater than the set value, the controller immediately controls the feeding mechanism 40 to stop feeding the sorting tray 30, and at the same time controls the avoidance mechanism to act, pushing the collection box 50 away from the sorting tray 30 to prevent unqualified diamonds from falling into the collection box 50. After the collection box 50 is pushed away, the aggregate chute 11 will be exposed, and the diamonds in the sorting tray 30 will fall into the aggregate chute 11 and be collected, and then return to the feeding mechanism 40. After treating (heating and / or ventilation) the diamonds to be sorted, that is, making the humidity of the diamonds to be sorted meet the sorting requirements, the avoidance mechanism then resets the collection box 50. After the vibration motor 31 starts and stabilizes, the feeding mechanism 40 can continue to feed the sorting tray 30 to perform the sorting work.

[0044] Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the avoidance mechanism is replaced by a cylinder. Using a cylinder can ensure quick action.

[0046] Embodiment 3

[0047] As Figures 5 to 6 shown, on the basis of Embodiment 1 or Embodiment 2, first slopes 23 are provided on both sides of the bottom of the base 20, and second slopes 15 adapted to the first slopes 23 are provided on the installation platform 10. The second slopes 15 are placed on both sides of the length direction of the aggregate chute 11, and the base 20 is slidably connected to the second slopes 15 through the first slopes 23. When the avoidance mechanism drives the base 20 away from the sorting tray 30, the base 20 moves towards the top of the second slope 15, that is, the base 20 can be lifted, so that when the collection box 50 is away from the sorting tray 30, its horizontal displacement distance is shorter, and it can also prevent unqualified diamonds from falling into the collection box 50. When the avoidance mechanism uses magnetic attraction as the power, it can better ensure the function of the electromagnet 61. When using a cylinder, the stroke of the cylinder can be shorter and the stability is better.

[0048] Embodiment 4

[0049] As Figures 7 to 8As shown in the figure, on the basis of Embodiment 1 or Embodiment 2, the present embodiment is provided with a first sliding rod 24 and a second sliding rod 25 on both sides of the base 20. The first sliding rod 24 is arranged at one end of the base 20 close to the sorting disk 30, and the second sliding rod 25 is arranged at one end of the base 20 far from the sorting disk 30. The installation platform 10 (baffle 12) is provided with a first sliding track 16 and a second sliding track 17. The first sliding rod 24 is inserted into the first sliding track 16 and is slidably connected thereto. The diameter of the first sliding rod 24 is adapted to the width of the first sliding track 16. The second sliding rod 25 is inserted into the second sliding track 17 and is slidably connected thereto. The diameter of the second sliding rod 25 is smaller than the width of the second sliding track 17. The first sliding track 16 is inclined, and the second sliding track 17 is horizontal. When the avoidance mechanism drives the base 20 away from the sorting disk 30, the first sliding rod 24 moves towards the higher part of the first sliding track 16. After such a setting, when the collection box 50 and the base 20 move away from the sorting disk 30, the ends of both of them close to the sorting disk 30 can be lifted to a certain extent. In this way, when the collection box 50 moves away from the sorting disk 30, even if the horizontal displacement distance is shorter, it can avoid the unqualified diamonds sorted from falling into the collection box 50 (the retaining wall 21 is lifted and skewed, thereby preventing the diamonds in the sorting disk 30 from falling into the collection box 50). Such a setting is also beneficial to the setting of the avoidance mechanism.

[0050] Embodiment 5

[0051] On the basis of any of the above embodiments, the present embodiment further adds a detection component for detecting the voltage, rotation speed and frequency of the vibration motor 31. The detection component can be integrally composed of a voltage sensor and an encoder. The detection of the voltage, rotation speed and frequency of the motor is a mature existing technology and will not be elaborated in this case. The detection component is connected to the controller. By setting the detection component, it is possible to stop feeding the sorting disk 30 in time when the vibration of the sorting disk 30 is abnormal, and to block the diamonds currently in the sorting disk 30 from falling into the collection box 50 in time, providing another processing method for the sorting machine in an abnormal state and further ensuring the sorting effect.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
