Glass bead has high refractive index, light refraction occurs after entering, and internal surface reflection, finally returns along the incident direction, forming inverse reflection. Glass bead has the advantages of light weight, low thermal conductivity, high strength, good chemical stability and the like. Glass bead is usually formed by heating glass raw materials during production, and is cooled and screened after forming.

[0003] In order to improve the screening efficiency of glass bead, a glass bead screening device for reflective material is disclosed in Chinese patent with publication number CN219540912 U. The patent includes a base, a support column and a screening bin. The glass bead is subjected to re-centrifugal screening through the cooperation of a rotating device, a turntable, a screening mesh plate and a rotating assembly, so that the screening rate is more efficient.

[0004] However, the centrifugal force generated by the rotation of the screening mesh plate in the above-mentioned patent can cause the glass bead to adhere to the mesh wall, resulting in the blocking of the filter holes by the larger particles, thereby reducing the subsequent screening efficiency. In addition, the rotation of the screening mesh plate in the above-mentioned patent can filter out small particles, but large particles remain inside the screening mesh plate and cannot be discharged, causing the workers to spend a lot of time cleaning the inside of the screening mesh plate, affecting the actual use effect.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a glass microsphere sieving device for reflective materials, including a base 1, the upper surface of which is welded and fixed to a cylinder 2, the bottom of which is welded and fixed to a base plate, the top of which is hinged to a cover plate 3, the inside of which is welded and fixed to a fixing plate 4, one end of which is welded and fixed to an operation box 5, the inner wall of which is connected and fixed to the operation box 5 via the fixing plate 4, the inside of which is rotatably connected to the outside of an eccentric rotating shaft 6, and the top of which is welded and fixed to a sieving cylinder 7. The screening cylinder 7 is positioned near the center of the cylinder body 2. The inner wall of the screening cylinder 7 is welded and fixed to the guide shroud 8. The outer side of the eccentric rotating shaft 6 is welded and fixed to the driven gear 9. The bottom of the eccentric rotating shaft 6 is rotatably connected to one end of the discharge pipe 10. The base 1 is fixedly connected to the upper surface of the box body 13. A screen plate 14 is installed inside the box body 13. The screen plate 14 is welded and fixed to one end of the connecting rod 17. The other end of the connecting rod 17 is welded and fixed to the moving plate 18. The side of the moving plate 18 is connected and fixed to the vibrating motor 19 by bolts. One side of the box body 13 is fixedly connected to the collection box 20.

[0024] A circular through hole is provided on the upper surface of the base 1, through which the base 1 communicates with the interior of the cylinder 2. The box 13 is located directly below the circular through hole, and the screening cylinder 7 is located directly below the cover plate 3. This ensures that the rotation amplitude of the screening cylinder 7 will not affect the material fed into the cover plate 3 and cause it to deviate from the interior of the screening cylinder 7. In addition, the rotation speed of the drive gear 12 can be controlled by the drive motor 11, thereby adjusting the centrifugal force and vibration amplitude of the screening cylinder 7 to enhance the actual use effect.

[0025] The inner wall of the cylinder 2 is welded and fixed to the annular guide plate, which is located below the operating box 5. The guide plate facilitates the transport of the microspheres sieved out by the centrifugal screening cylinder 7 to the inside of the box 13, preventing them from accumulating inside the cylinder 2.

[0026] A drive motor 11 is fixedly installed inside the control box 5. The output end of the drive motor 11 is welded and fixed to the drive gear 12. The outer side of the drive gear 12 is meshed with the driven gear 9. One end of the discharge pipe 10 is connected to the inside of the screening cylinder 7 through the eccentric rotating shaft 6. The other end of the discharge pipe 10 is inclined downward and extends to the outside of the cylinder 2. The drive motor 11 causes the drive gear 12 to rotate, which in turn drives the eccentric rotating shaft 6 and the driven gear 9 to rotate synchronously, thereby causing the screening cylinder 7 to rotate. Therefore, the screening cylinder 7 will rotate eccentrically and generate vibration.

[0027] The inner wall of the housing 13 is welded and fixed to one end of the slide rod 15. A spring 16 is sleeved on the outer side of the slide rod 15, and the spring 16 is located between the housing 13 and the sieve plate 14. A circular through hole is opened on the side of the sieve plate 14, and the sieve plate 14 is slidably connected to the outer side of the slide rod 15 through the circular through hole. One end of the connecting rod 17 extends into the inside of the housing 13 and is welded and fixed to the side of the sieve plate 14. The housing 13 is slidably engaged with the outer side of the connecting rod 17 through the circular through hole. A matching through hole is opened on the inner wall of the housing 13, and the housing 13 communicates with the inside of the collection box 20 through the matching through hole. The sieved microspheres are transported and stored through the collection box 20.

[0028] Working principle: In use, open the cover plate 3 and add glass microspheres into the cylinder 2 and then into the screening cylinder 7. The drive motor 11 drives the drive gear 12 to rotate, which in turn drives the eccentric shaft 6 and the driven gear 9 to rotate synchronously, thus causing the screening cylinder 7 to rotate. Because the eccentric shaft 6 is eccentrically positioned relative to the bottom of the screening cylinder 7, the screening cylinder 7 will rotate eccentrically, thereby generating vibration. This prevents large microspheres from clogging the filter holes of the screening cylinder 7 due to centrifugal force during rotation. The vibration of the screening cylinder 7 can also improve the efficiency of microsphere screening. The guide hood 8 facilitates the flow of large microspheres towards the screening cylinder by gravity. At the bottom of the 7th chamber, the particles enter the eccentric rotating shaft 6 and are discharged from the discharge pipe 10, achieving the collection of large microspheres. The screened microspheres fall and move into the box 13. The vibrating motor 19 drives the moving plate 18 to vibrate, and the connecting rod 17 drives several screen plates 14 to vibrate synchronously, so that the screen plates 14 move back and forth on the outside of the sliding rod 15 to achieve the vibration effect, thereby improving the screening effect of the screen plates 14. Then, the glass microspheres flow to the collection box 20 on the inclined screen plate 14. By setting multiple collection boxes 20 at the top and bottom, microspheres of different radii can be screened, collected and stored, enhancing the actual screening effect. The drawer at the bottom of the box 13 further enhances the convenience of screening and collection.
