[0036] Embodiments:

[0037] Referring to Figures 1-11 A glass bead defect detection and sorting device, comprising a support 1 and an outer sieve cylinder 2, the support 1 is fixedly connected with a feeding hopper 11, the bottom end of the feeding hopper 11 extends to the inside of the inner sieve cylinder 10, that is, the glass beads are transported to the inside of the inner sieve cylinder 10, further comprising: a drive shaft 4 rotatably connected to one side of the support 1 close to the outer sieve cylinder 2, a drive mechanism is arranged between the drive shaft 4 and the support 1 for driving the drive shaft 4 to rotate, wherein the outer wall of the outer sieve cylinder 2 is fixedly connected with a drive ring 8 which is fitted with the drive mechanism; the inner sieve cylinder 10 is rotatably connected to the inside of the outer sieve cylinder 2, a linkage assembly is arranged between the inner sieve cylinder 10 and the drive shaft 4 for driving the inner sieve cylinder 10 to rotate in the opposite direction and at different speeds along the outer sieve cylinder 2 when the drive shaft 4 rotates; an anti-blocking mechanism is arranged on the drive shaft 4 and the outer sieve cylinder 2 for blowing air into the outer sieve cylinder 2 and the inner sieve cylinder 10 and intermittently knocking the outer sieve cylinder 2 and the inner sieve cylinder 10; a guide hopper 30 is fixedly connected to one side of the support 1 close to the bottom end of the outer sieve cylinder 2 and the inner sieve cylinder 10, the inside of the guide hopper 30 is symmetrically fixedly connected with a partition plate 31, wherein the guide hopper 30 is provided with a detection and sorting mechanism connected with the drive shaft 4 for sorting glass beads with the same type of defects to the specified position of the partition plate 31 and the guide hopper 30.

[0038] In the embodiment, the glass beads to be detected and sorted are added to the inside of the inner screen cylinder 10 from the feeding hopper 11, while the outer screen cylinder 2 and the inner screen cylinder 10 are driven to rotate by the driving mechanism and the linkage assembly. It should be noted that the size of the screen holes of the inner screen cylinder 10 is larger than that of the outer screen cylinder 2, and the inner screen cylinder 10 and the outer screen cylinder 2 are both arranged obliquely. During rotation, the large-diameter glass beads stay inside the inner screen cylinder 10, and the small-diameter and qualified-diameter glass beads fall into the outer screen cylinder 2 under the action of gravity. Then, the small-diameter glass beads fall from the inside of the outer screen cylinder 2 to the outside under the action of gravity, thereby realizing the particle size sorting of the glass beads. Further, in the sorting process, the debris in the screen holes of the outer screen cylinder 2 and the inner screen cylinder 10 can be cleaned by the anti-blocking mechanism to prevent the outer screen cylinder 2 and the inner screen cylinder 10 from being blocked. In addition, the outer screen cylinder 2 and the inner screen cylinder 10 can be intermittently and uniformly knocked, further improving the anti-blocking effect of the outer screen cylinder 2 and the inner screen cylinder 10. The glass beads with qualified particle size after sorting fall onto the guide hopper 30, and are subjected to airflow sorting, electrostatic sorting and automatic robot sorting in sequence, and the glass beads with different types of defects are arranged at different positions along the guide hopper 30. This not only improves the detection and sorting effect of the glass beads, but also improves the detection accuracy of the glass beads.

[0039] With reference to Figure 2 and Figure 10 , the driving mechanism includes a driving motor 3 fixedly connected to the support 1 near one set of driving shafts 4. The driving motor 3 and the driving shafts 4 are both provided with driving wheel sets 5. The first belt 6 is sleeved between the two sets of driving wheel sets 5. The driving shafts 4 are fixedly connected with guide wheels 7 that are in close contact with the driving rings 8.

[0040] In the embodiment, when the glass beads are sorted, the driving motor 3 is started to drive the driving shafts 4 to rotate through the driving wheel sets 5 and the first belt 6, thereby driving the guide wheels 7 to rotate. Under the action of the driving rings 8, the outer screen cylinder 2 is driven to rotate on the support 1. It should be noted that the guide wheels 7 can be provided with limit pieces to ensure that the guide wheels 7 are in close contact with the driving rings 8 during rotation. The driving of the guide wheels 7 to drive the driving rings 8 to rotate mainly relies on the friction between the driving rings 8 and the guide wheels 7, which is a conventional means in the prior art, and thus will not be described in detail.

[0041] With reference to Figure 1 and Figure 4 , the linkage assembly includes a set of driven wheel sets 12 fixedly connected to the driving shafts 4 and the inner screen cylinder 10. The second belt 13 is sleeved between the two sets of driven wheel sets 12 to drive the inner screen cylinder 10 and the outer screen cylinder 2 to synchronously rotate at different speeds.

[0042] In the embodiment, when the guide wheel 7 near the driving motor 3 rotates, the guide wheel 7 on the other side rotates synchronously under the action of the driving ring 8, and under the action of the driven wheel set 12 and the second belt 13, the inner screen cylinder 10 drives the outer screen cylinder 2 to rotate in the opposite direction, that is, at this time, the inner screen cylinder 10 and the outer screen cylinder 2 have a relative rotation trend, and in this process, the glass beads with large particle size stay in the inner screen cylinder 10 and are gradually transported downward, the glass beads with small particle size fall from the inside to the outside of the outer screen cylinder 2, and the glass beads with qualified particle size stay between the outer screen cylinder 2 and the inner screen cylinder 10.

[0043] With reference to Figure 1 , Figure 5 and Figure 6 , the anti-blocking mechanism comprises a wind supply device 9 fixedly connected to the support 1 and connected with the driving shaft 4, an air outlet of the wind supply device 9 is attached to the outer wall of the outer screen cylinder 2, and is used to blow the dust and the like blocked in the screen holes of the outer screen cylinder 2 to the inside of the outer screen cylinder 2, wherein an inner cylinder anti-blocking assembly is arranged between the outer screen cylinder 2 and the wind supply device 9, and a vibration assembly is arranged on the inner wall of the outer screen cylinder 2.

[0044] In the embodiment, when the driving shaft 4 rotates, the wind supply device 9 is driven to rotate, and the specific structure of the wind supply device 9 can refer to the technical solutions in the prior art, such as a centrifugal fan, that is, during the rotation of the outer screen cylinder 2, the wind force generated by the wind supply device 9 blows from the outside to the inside of the outer screen cylinder 2, so as to blow the debris in the screen holes to the inside of the outer screen cylinder 2, thereby avoiding the blocking of the outer screen cylinder 2 during the separation, and it needs to be explained that when the outer screen cylinder 2 rotates, the glass beads always roll at the bottom of the outer screen cylinder 2 under the action of gravity, so the glass beads that are not separated will not be discharged along the upper part of the outer screen cylinder 2, and the directional separation of the glass beads can also be realized by arranging a protective cover outside the outer screen cylinder 2.

[0045] With reference to Figures 4-6 , the inner cylinder anti-blocking assembly comprises an air slide ring 14 fixedly connected to the outer wall of the outer screen cylinder 2, a gas supply pipe 15 in communication between the air slide ring 14 and the wind supply device 9, a plurality of connecting shafts 16 fixedly connected to the inner wall of the outer screen cylinder 2, a guide block 17 fixedly connected to the connecting shaft 16 and attached to the inner wall of the outer screen cylinder 2 and the outer wall of the inner screen cylinder 10, and a gas blowing channel 18 formed in the guide block 17, wherein the exhaust port of the gas blowing channel 18 is close to the outer wall of the inner screen cylinder 10, and the gas blowing channel 18 is connected in communication with the air slide ring 14 through a pipeline.

[0046] In the embodiment, it needs to be explained that the air slide ring 14 is a conventional means in the prior art, which can realize stable delivery of the gas when the inner screen cylinder 10 rotates, so it is not described repeatedly, that is, in the process of rotating of the outer screen cylinder 2 and the inner screen cylinder 10, part of the gas generated by the air supply device 9 first enters the inside of the air slide ring 14 through the air supply pipe 15, and then enters the inside of the flow guide block 17 through the pipeline, so that the gas is blown from the outside of the inner screen cylinder 10 to the inside, thereby cleaning the debris in the screen holes of the inner screen cylinder 10, and through the different speed rotation of the outer screen cylinder 2 and the inner screen cylinder 10, the screen holes at different positions of the inner screen cylinder 10 are uniformly cleaned.

[0047] With reference to Figure 5 , Figure 6 and Figure 11 , the vibration assembly comprises a gear ring 19 fixedly connected to the outer wall of the inner screen cylinder 10, a rotating shaft 20 rotatably connected to the inside of the outer screen cylinder 2, a drive gear 21 fixedly connected to the rotating shaft 20 and engaged with the gear ring 19, a sleeve ring 22 fixedly connected to the rotating shaft 20, a plurality of sealing strips 23 fixedly connected to the outer wall of the sleeve ring 22, a vibration strip 24 slidably connected to the inside of the sealing strip 23, and a plurality of springs 25 fixedly connected between the vibration strip 24 and the sealing strip 23.

[0048] In the embodiment, under the action of the gear ring 19, the drive gear 21 and the rotating shaft 20 are driven to rotate when the outer screen cylinder 2 and the inner screen cylinder 10 rotate, thereby driving the sleeve ring 22 and the sealing strip 23 to rotate, when the sealing strip 23 moves away from the outer screen cylinder 2 and the inner screen cylinder 10, the vibration strip 24 extends outward under the action of the spring 25, when the sealing strip 23 approaches the outer screen cylinder 2 and the inner screen cylinder 10, the vibration strip 24 knocks the outer screen cylinder 2 and the inner screen cylinder 10, and then the vibration strip 24 is accommodated in the inside of the sealing strip 23, and the above process is repeated, thereby intermittently and uniformly knocking different positions of the outer screen cylinder 2 and the inner screen cylinder 10, further improving the anti-blocking effect of the outer screen cylinder 2 and the inner screen cylinder 10.

[0049] With reference to Figure 1 and Figure 3 , the first discharge plate 27 and the second discharge plate 28 are fixedly connected to the support 1, the third discharge plate 29 is fixedly connected to the second discharge plate 28, the first discharge plate 27 is located at the bottom of the outer screen cylinder 2, the second discharge plate 28 and the third discharge plate 29 are respectively close to the bottom end of the inner screen cylinder 10 of the outer screen cylinder 2, wherein the bottom end of the outer screen cylinder 2 is provided with a discharge port 26, the size between the second discharge plate 28 and the third discharge plate 29 matches the discharge port 26, and the bottom end of the second discharge plate 28 is located above the material guide hopper 30.

The large-diameter glass beads stay in the inner sieve cylinder 10, and gradually roll down along the inner sieve cylinder 10, and finally fall down on the third discharge plate 29, and are collected through the bottom end of the third discharge plate 29. The qualified-diameter glass beads fall down between the outer sieve cylinder 2 and the inner sieve cylinder 10 to the second discharge plate 28, and finally fall down from the bottom end of the second discharge plate 28 to the guide hopper 30, so that the particle size sorting of the glass beads is realized.

[0051] With reference to Figure 7 and Figure 9 , the detection and sorting mechanism comprises a flow guide 32 fixedly connected to the side wall of the guide hopper 30, and a blowing pipe 33 in communication between the flow guide 32 and the air supply device 9, for blowing the light-weight defective glass beads to the side between the separation plate 31 and the guide hopper 30 away from the flow guide 32.

[0052] In the embodiment, during the process that the glass beads fall down from the second discharge plate 28 to the guide hopper 30, part of the gas generated by the air supply device 9 is delivered to the flow guide 32 through the blowing pipe 33, and is blown to the falling glass beads through the flow guide 32. The light-weight glass beads are blown to the side away from the flow guide 32, and then fall down between the separation plate 31 and the inner wall of the guide hopper 30.

[0054] In the embodiment, it needs to be explained that the electrostatic field can be arranged between the fixed plate 36 and the partition plate 31 between the flow guide 32, so that the glass beads after the airflow sorting pass through the electrostatic field, in the process, the glass beads containing impurities are electrostatic, and then adsorbed on the electrode plate 42, the driving shaft 4 rotates, the bevel gear set 35 drives the vertical shaft 34 to rotate, thereby driving the linkage shaft 37 to rotate through the linkage wheel set 38 and the third belt 39, driving the roller 40 and the conveying belt 41 to rotate, wherein the electrode plate 42 is made of soft material, and the glass beads adsorbed on the surface of the electrode plate 42 move to the side close to the flow guide 32 with the rotation of the electrode plate 42, and the glass beads will not fall off when passing through the groove 45, when the electrode plate 42 rotates to the partition plate 31, the partition plate 31 will scrape the glass beads adsorbed on the electrode plate 42, and then fall off between the partition plate 31 and the inner wall of the material guide hopper 30, and the glass beads without impurities continue to be conveyed between the two groups of partition plates 31, in addition, the size of the gap between the electrode plate 42 and the partition plate 31 is smaller than the size of a single glass bead, so as to ensure that the glass beads on the electrode plate 42 are scraped completely, and the cost of glass bead detection and sorting is also reduced.
