[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic particle screening device. Background Art

[0002] When traditional screening devices screen plastic particles, the plastic particles stay on the filter screen for a short time, and it is very easy for the plastic particles to move to the discharge port before they can be screened, resulting in poor screening effect.

[0003] Existing announcement number CN219748622U discloses a plastic particle screening device, including a storage part, a screening part and a feed hopper, and also includes a screening bin and a driving mechanism, the screening bin is arranged on the inner side of the screening part, the opposite side walls of the screening bin are arranged in an arc shape, and a screen is arranged at the center of the screening bin; the driving mechanism drives the screen to rotate back and forth along the rotating shaft; through the arranged screen and the screening bin with opposite side walls arranged in an arc shape, the driving mechanism drives the screen to rotate back and forth along the rotating shaft, and the plastic particles to be screened roll back and forth on the upper end of the screen, so that small particles of plastic particles are fully screened out, and through the coordinated arrangement of the gear, the arc-shaped slider and the tooth block, the driving motor drives the gear to rotate back and forth, and the gear drives the arc-shaped slider through the tooth block to carry the screen to reciprocate around the rotating shaft. Compared with directly driving the rotating shaft to rotate the screen, the above device reduces driving energy consumption.

[0004] However, when the above-mentioned plastic particle screening device is in use, the larger plastic particles after screening remain above the filter screen, which is likely to cause the filter screen to be clogged when used for a long time, resulting in poor screening effect.

[0006] To achieve the above-mentioned purpose, the utility model provides a plastic particle screening device, comprising a screening box, a screening assembly, a transmission assembly, a collecting assembly and a sealing assembly; the screening assembly comprises a screening frame, a screening frame, a spring rod, a pressing block and a wear-resistant block, the screening frame is slidably connected to the screening box and is located inside the screening box, the screening frame is fixedly connected to the screening frame and is located between the screening blocks, the number of the spring rods is multiple, and the multiple spring rods are respectively fixedly connected to the screening box and are respectively located at the top of the screening frame, the pressing block is fixedly connected to the spring rod and is respectively located between the spring rod and the screening frame, the number of the wear-resistant blocks is multiple, and the multiple wear-resistant blocks are respectively fixedly connected to the screening frame and are respectively located at the bottom of the screening frame, the transmission assembly, the collecting assembly and the sealing assembly are respectively connected to the screening box.

[0007] In which, the transmission assembly includes a transmission shaft, a cam and a transmission wheel.

When used for a long time, the sieve frame and the sieve frame can be taken out of the sieve box, so that the sieve frame can be cleaned easily, thereby avoiding clogging of the sieve frame. This solves the problem that when the plastic particle screening device is in use, larger plastic particles after screening are retained above the filter screen, which is easy to cause clogging of the filter screen when used for a long time, resulting in poor screening effect.
