[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a dual-axis collaborative control jewelry color sorting device, including a color sorting platform 1, on which a first color sorting part 3 and a second color sorting part 301 are symmetrically arranged for color sorting and classification of jewelry. Specifically, the color selection table 1 is further provided with a collecting hopper 2 for temporarily storing the jewelry to be color selected, and the collecting hopper 2 is provided with multiple screening modules for classifying the jewelry of different particle size ranges; it can be explained that the jewelry to be color selected is poured into the collecting hopper 2, and the multiple screening modules arranged in the collecting hopper 2 are used for pre-screening the jewelry, so as to facilitate subsequent fine classification of the jewelry by the color selection machine.

[0022] It can be seen from Figures 4-7 The bottom of the collecting hopper 2 is symmetrically provided with two groups of discharge ports 204, and the two groups of discharge ports 204 are respectively connected with the material conveying module, so as to convey the classified jewelry to the first color selection part 3 and the second color selection part 301 respectively; It should be further explained that the jewelry in the collecting hopper 2 of the embodiment is pre-screened and can be discharged to the material conveying module through the discharge port 204 under the action of gravity, and then conveyed to the first color selection part 3 and the second color selection part 301 for color selection and classification. Compared with the screening machine used in the prior art for screening the jewelry, the multiple screening modules are integrated into the collecting hopper of the color selection machine in the embodiment, which avoids the cumbersome screening process. At the same time, the two color selection parts are arranged in the embodiment, so that the color selection of the jewelry can be carried out at the same time, and the color selection efficiency is further improved.

[0023] Embodiment 2

[0024] Based on the embodiment 1, it can be seen from Figures 6-9 The multiple screening modules include a first screen plate 8, a second screen plate 810 and a third screen plate 812 arranged in the collecting hopper 2 from top to bottom, the first screen plate 8 is uniformly provided with first screen holes 802, the second screen plate 810 is uniformly provided with second screen holes 811, and the third screen plate 812 is uniformly provided with third screen holes 813, wherein the diameters of the first screen holes 802, the second screen holes 811 and the third screen holes 813 gradually decrease; it can be explained that when the jewelry is color selected, the jewelry to be color selected is first poured onto the first screen plate 8, and the first screen holes 802 are used for first-level screening of the jewelry. The jewelry with a particle size smaller than the diameter of the first screen holes 802 falls onto the second screen plate 810, and the second screen holes 811 are used for second-level screening of the jewelry. The jewelry with a particle size smaller than the diameter of the second screen holes 811 falls onto the third screen plate 812, and the jewelry with a particle size smaller than the diameter of the third screen holes 813 falls to the bottom of the collecting hopper 2, so that the jewelry falling to the bottom of the collecting hopper 2 is screened first in the screening process.

[0025] In addition, in order to improve the screening efficiency of each screen plate for the jewelry, a vibration motor can be arranged on the collecting hopper 2 to vibrate the collecting hopper 2 and improve the screening efficiency of each screen plate. The specific type and principle of the vibration motor are not limited in the embodiment, and the actual application requirements can be met.

[0026] As an embodiment of the present embodiment, the multi-stage screening module further comprises an adjusting mechanism for sequentially driving the third sieve plate 812, the second sieve plate 810 and the first sieve plate 8 to rotate; it can be explained that after the color selection of all the jewelry at the bottom of the collecting hopper 2 is completed, i.e. the color selection of the first batch of jewelry is completed, the adjusting mechanism can first drive the third sieve plate 812 to deflect downward by a certain angle (see Figure 9 ), so that the jewelry on the third sieve plate 812 can be discharged to the bottom of the collecting hopper 2 under the action of gravity to complete the color selection of the second batch of jewelry, correspondingly, after the color selection of the jewelry on the third sieve plate 812 is completed, the adjusting mechanism drives the second sieve plate 810 to deflect downward by a certain angle to color select the jewelry on the second sieve plate 810 to complete the color selection of the third batch of jewelry, similarly, the jewelry on the first sieve plate 8 is finally color selected to complete the color selection of the fourth batch of jewelry, therefore, the present embodiment can realize the effect of batch color selection and screening by screening the jewelry through the multi-stage sieve plate and then sequentially outputting the jewelry on each sieve plate through the adjusting mechanism, which has higher automation and effectively improves the screening efficiency.

[0027] In the present embodiment, in order to sequentially output each batch of jewelry, please refer to Figures 2-4 and Figure 6The material conveying module comprises a stirring bucket 201 connected with the discharge port 204, the bottom of the stirring bucket 201 is communicated with a discharge pipe 203, the inner diameter of the discharge pipe 203 is larger than the hole diameter of the first sieve hole 802, wherein the bottom of the discharge pipe 203 is slidingly provided with a discharge plate 601, the discharge plate 601 is slidingly attached with the discharge pipe 203, the first conduit 602, the second conduit 603, the third conduit 604 and the fourth conduit 605 are sequentially fixedly arranged at the bottom of the discharge plate 601, the inner diameters of the first conduit 602, the second conduit 603, the third conduit 604 and the fourth conduit 605 gradually increase, the receiving holes 607 connected with the conduits are arranged on the discharge plate 601, the hole diameters of the receiving holes 607 are same with the inner diameters of the corresponding conduits, the material conveying module further comprises a driving electric cylinder 606 fixed on the color selection table 1, the driving end of the driving electric cylinder 606 is fixed with the discharge plates 601 on both sides through a connecting plate; it can be explained that in the initial state, the first conduit 602 is in a state of communication with the discharge pipe 203, at this time, the first batch of jewelry in the collecting hopper 2 can be color selected, after the color selection of the first batch of jewelry is completed, the discharge plate 601 can be driven to slide by the driving electric cylinder 606, so that the second conduit 603 is connected with the discharge pipe 203, to complete the color selection of the second batch of jewelry, after the completion, the discharge plate 601 is driven to slide by the driving electric cylinder 606, so that the third conduit 604 is connected with the discharge pipe 203, to complete the color selection of the third batch of jewelry, after the completion, the discharge plate 601 is driven to slide by the driving electric cylinder 606, so that the fourth conduit 605 is connected with the discharge pipe 203, to finally complete the color selection of the fourth batch of jewelry, in the whole process of jewelry color selection, the pre-screening of the jewelry based on the multi-stage screening module can be realized, the conduits with different inner diameters are connected with the discharge pipe 203 in real time, and then the effect that the jewelry of different levels is conveyed to the color selection part one by one can be realized, the conduits do not need to be switched manually, and the automation degree is higher.

[0028] In addition, in order to ensure that the jewelry in the stirring bucket 201 can stably fall to the discharge pipe 203, in the embodiment, stirring vanes are arranged in the stirring bucket 201, and the stirring vanes are fixedly connected with the output end of the stirring motor 202 fixed on the stirring bucket 201; specifically, after the jewelry falls into the stirring bucket 201, the stirring vanes can be driven to rotate by the stirring motor 202, so as to stir the jewelry, so that the jewelry can quickly fall to the discharge pipe 203.

[0029] It can be seen from Figures 2-3 and Figures 5-7The adjusting mechanism comprises a support shaft 801 fixed to one side of each screen plate, both ends of the support shaft 801 connected with the first screen plate 8 penetrating through the sidewall of the collecting hopper 2 and being fixed with the first gear 513, both ends of the support shaft 801 connected with the second screen plate 810 penetrating through the sidewall of the collecting hopper 2 and being fixed with the second gear 512, both ends of the support shaft 801 connected with the third screen plate 812 penetrating through the sidewall of the collecting hopper 2 and being fixed with the third gear 803, wherein the two sides of the collecting hopper 2 are symmetrically provided with adjusting plates 502, the two adjusting plates 502 are connected with lifting mechanisms for driving the lifting of the adjusting plates 502, the adjusting plate 502 is sequentially provided with a first rack 511 for engaging with the first gear 513, a second rack 510 for engaging with the second gear 512 and a third rack 509 for engaging with the third gear 803, and the distance between the third gear 803 and the third rack 509, the distance between the second gear 512 and the second rack 510 and the distance between the first gear 513 and the first rack 511 gradually decrease in the initial state. It can be explained that the distance between the third gear 803 and the third rack 509 is the smallest in the initial state, when the lifting mechanism drives the upward movement of the adjusting plate 502, the third rack 509 drives the third screen plate 812 to deflect downward by a certain angle through the engagement with the third gear 803, with the continuous upward movement of the adjusting plate 502, the second rack 510 engages with the second gear 512, thereby driving the second screen plate 810 to deflect downward by a certain angle, when the adjusting plate 502 continues to move upward, the first gear 513 engages with the first rack 511, thereby driving the first screen plate 8 to deflect downward by a certain angle, therefore, the embodiment only needs to drive the upward movement of the adjusting plate 502 through the lifting mechanism, thereby achieving the effect of sequentially driving the deflection of the third screen plate 812, the second screen plate 810 and the first screen plate 8. The embodiment does not need to set multiple servo driving devices to adjust the deflection of different screen plates, which not only reduces the production cost, but also ensures the stability of the sequential deflection of the screen plates. Correspondingly, when the lifting mechanism drives the downward movement of the adjusting plate 502, the screen plates can be simultaneously driven to horizontally reset.

[0030] Specifically, refer to Figures 2-3 and Figures 5-7The lifting mechanism comprises a guide rod 5 fixed to the collecting hopper 2, a guide plate 501 fixedly connected with two side adjusting plates 502 is sleeved and slid on the guide rod 5, the bottom end of the guide rod 5 is slidably connected with a lifting plate 504, the lifting plate 504 is fixed with the guide plate 501 through a lifting rod 508, the two sides of the lifting plate 504 are symmetrically fixedly arranged with inclined plates 505, a telescopic spring 503 is further arranged on the guide rod 5, one end of the telescopic spring 503 is fixed with the lifting plate 504, and the other end is fixed with the guide plate 501, wherein the end of the two side discharging plates 601 is fixedly arranged with a limiting rod 507, and the end of the limiting rod 507 is rotatably arranged with a guide wheel 506 which is in rolling abutment with the inclined plate 505; it can be explained that, in the process that the driving electric cylinder 606 drives the first guide pipe 602, the second guide pipe 603, the third guide pipe 604 and the fourth guide pipe 605 to be connected with the discharging pipe 203, the discharging plate 601 drives the guide wheel 506 to move synchronously through the limiting rod 507, the guide wheel 506 drives the lifting plate 504 to gradually rise through the rolling abutment with the inclined plate 505, and the lifting plate 504 drives the guide plate 501 to rise on the guide rod 5 through the lifting rod 508, so that the telescopic spring 503 is stretched and generates elastic force, and then the guide plate 501 drives the two side adjusting plates 502 to rise, and correspondingly, when the driving end of the driving electric cylinder 606 is reset, the telescopic spring 503 can synchronously drive each component to reset; based on this, in the process that the driving electric cylinder 606 adjusts each guide pipe to be connected with the discharging pipe 203 in turn, the effect that each screen plate rotation is adjusted in turn and synchronously can be achieved, without the need of setting other servo driving devices to drive the adjusting plate 502 to rise, and the synchronism and stability are higher.

[0031] In addition, after each rack driving gear rotates, in order to avoid the rotation of the gear, in the embodiment, one end of each gear away from the collecting hopper 2 is fixed with a telescopic rod 805, the other end of the telescopic rod 805 is slidably inserted with a sleeve 807, a plurality of groups of strip-shaped clamping bases 806 are fixedly arranged on the telescopic rod 805 in a circumferential array, a strip-shaped clamping groove corresponding to the strip-shaped clamping base 806 is formed in the sleeve 807 in a one-to-one correspondence sliding fit, and the other end of the sleeve 807 is fixed with a screw rod 808, wherein the L-shaped support 804 is fixedly arranged on the collecting hopper 2 and is screw-connected with the screw rod 808; it can be explained that the screw rod 808 can be synchronously driven to rotate in the L-shaped support 804 through the telescopic rod 805 and the sleeve 807 when the gear rotates, and since a certain torsional force is required for the rotation of the screw rod 808, the gear will not rotate when the rack is not engaged with the gear, and the stability is higher.

The color selection process is the prior art, and no detailed description is given.

[0033] As a further scheme of the embodiment, refer to Figures 6-9 In the process of pre-screening the jewelry, in order to avoid the jewelry rolling off from the edge of the screen plate, U-shaped baffles 816 are fixedly arranged on each screen plate, and the opening end of the U-shaped baffle 816 is provided with a sealing plate 809 connected with a rotating mechanism for driving the rotation of the sealing plate 809; It can be explained that when each screen plate is in a horizontal state, the U-shaped baffle 816 and the sealing plate 809 form a limiting space to avoid the jewelry on the screen plate rolling off from the edge, when it is necessary to discharge the jewelry on the screen plate for screening, the rotating mechanism can synchronously drive the sealing plate 809 to deflect downward as the screen plate deflects downward, so that the jewelry on the screen plate can roll off from the opening of the U-shaped baffle 816; Specifically, the sealing plate 809 is rotatably arranged at the opening end of the U-shaped baffle 816, and the rotating mechanism includes adjusting gears 814 fixed at both ends of the sealing plate 809, and arc-shaped racks 815 corresponding to the adjusting gears 814 are fixedly arranged on both sides in the aggregate hopper 2; It can be explained that during the deflection of the screen plate, the adjusting gears 814 can be synchronously driven to move, and the adjusting gears 814 can drive the sealing plate 809 to rotate by engaging with the arc-shaped racks 815, so as to open the opening of the U-shaped baffle 816, facilitating the discharge of the jewelry.
