The first connecting ear plate 136 is fixedly connected to the first screening body 10. When the first screening body 10 vibrates due to the vibration screening mechanism 9, it drives the first connecting ear plate 136 to vibrate. The lower end of the first connecting ear plate 136 is fixedly connected to the top connecting rod 135, thereby driving the top connecting rod 135 to vibrate. The lower end of the top connecting rod 135 is fixedly connected to the second connecting ear plate 134. The second connecting ear plate 134 is fixedly connected to the second screening body 11. Thus, the second connecting ear plate 134 can drive the second screening body 11 to perform vibration screening during vibration. The lower end of the second connecting ear plate 134 is fixedly connected to the bottom connecting rod 133. The second connecting ear plate 134 can also drive the lower bottom connecting rod 133 to vibrate. The lower end of the bottom connecting rod 133 is fixedly connected to the third connecting ear plate 132. Thus, the bottom connecting rod 133 can drive the third connecting ear plate 132 to vibrate. The third connecting ear plate 132 is fixedly connected to the third screening body 12. In this way, it can drive the third screening body 12 to perform vibration screening. The lower end of the third connecting ear plate 132 is connected to the support strong spring 131. The support strong spring 131 is fixedly connected to the inner bottom end of the screening housing 4. Elastic vibration screening can be performed through the support strong spring 131.

[0034] Working principle: When in use, support column feet 1 are fixedly connected to the four lower corners of the screening housing 4, which can support stable placement. The feed pipe 3 adds the received ABS resin material particles to the first screening body 10 for screening. The screen aperture of the first screening body 10 is slightly larger than the target particle diameter, so that particles with a diameter larger than the required size or adhered particles are screened out. The shaking force generated by the vibration screening mechanism 9 can be transmitted to the first screening body 10, and the first screening body 10 can shake for screening. The large-particle ABS resin material on the first screening body 10 is discharged to the outside through the large-particle discharge hopper 5 for collection. A blower 2 is installed on the screening housing 4 at the rear between the first screening body 10 and the second screening body 11. The wind generated by the blower 2 can blow the dust, so that the particles and the dust are separated for screening. The dust is discharged to the outside and collected in the collection filter bag through the dust outlet cover 6 to avoid polluting the external environment. The third screening body 12 can receive the ABS resin material particles screened by the second screening body 11. The finished ABS resin material particles are discharged to the outside through the finished product discharge hopper 7 for collection. The unqualified ABS resin material particles are screened and fall to the bottom end inside the screening housing 4 and are collected through the defective product discharge hopper 8. The device selects resin particles with too large or too small particle sizes through multiple layers of screens, removes the waste chips and powders in the particles, so as to obtain homogenized ABS resin particles, which is more efficient during screening and can effectively remove waste chips and powders, thus meeting the requirements of later processing and production.
