Technical Field

[0001] This utility model relates to the field of particle screening technology in recycled plastic processing, and specifically to a particle screening device for recycled plastic processing. Background Technology

[0002] Recycled plastics refer to plastic raw materials obtained by processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. It is a reuse of plastics. Screening is a method of separating particle groups according to powder properties such as particle size, specific gravity, charge, and magnetism. The operation of separating mixtures of different particle sizes into various particle size grades using a perforated sieve surface is called screening.

[0003] The current publication number CN215921007U discloses a granule screening device for plastic processing, relating to the field of plastic processing. This granule screening device includes a feed box and a discharge box. The feed box is located above the discharge box and is fixedly connected to it by four U-shaped rods. A first screening frame is fixedly installed on the upper surface of the discharge box, and a first screen is installed in the middle of the first screening frame. A first through groove communicating with the interior of the first screening frame is opened on its left side. A second screening frame is arranged above the first screening frame, with its left end hinged to the left end of the first screening frame. A second screen is installed in the middle of the second screening frame. This granule screening device for plastic processing, by setting up a motor, a first screening frame, and a second screening frame, achieves the effect of screening plastic granules first during plastic processing, solving the problem of difficult screening and separation of larger substances in existing screening devices.

[0004] To solve the screening problem, the existing technology uses a motor, a first screening frame, and a second screening frame to screen plastic particles during plastic processing. However, after long-term use, the screens may wear out and become clogged, making replacement difficult. This leads to uneven screening and reduced efficiency. Utility Model Content

The collection unit 2 includes a screening box 21, which is fixedly connected to the inner side of the top surface of the support leg 1. A feed inlet 22 is fixedly connected to one side of the screening box 21, and a collection box 23 is slidably connected to the bottom surface inside the screening box 21. A collection box 24 is slidably connected to one side of the screening box 21. A T-shaped rod 25 is fixedly connected inside the screening box 21.

One end of the spring 26 is fixedly connected to the bottom surface of the mounting frame 31. The recycled plastic particles are screened by a screening screen 36 set inside the mounting frame 31. During the screening process, recycled plastic particles that meet the standards enter the collection box 23 for collection, while those that do not meet the standards enter the collection box 24 for collection. At the same time, when the mounting frame 31 vibrates, it pushes the spring 26 inside the T-shaped rod 25 to extend and retract, further improving the screening effect of the screening screen 36. After long-term use, the T-shaped rod 23 can be pulled out from the inside of the connecting frame 35, and the connecting frame 35 can be removed from the inside of the mounting frame 31. The screening screen 36 inside can then be cleaned and replaced.

Simultaneously, it moves the mounting frame 31 inside the guide rod 47. The incoming recycled plastic granules are screened by the screening screen 36 located inside the mounting frame 31. During the screening process, recycled plastic granules that meet the standards are collected in the first collection box 23, while those that do not meet the standards are collected in the second collection box 24. Meanwhile, the mounting frame 31 vibrates... Simultaneously, the spring 26 inside the T-shaped rod 25 extends and retracts, further improving the screening effect of the screening screen 36. After prolonged use, the T-shaped rod 33 is pulled out from the inside of the connecting frame 35, and the connecting frame 35 is removed from the inside of the mounting frame 31. The screening screen 36 inside is then cleaned and replaced. During the screening process, the dust generated is controlled by the fan 52, and the dust is transported to the inside of the dust collection box 51 through the dust suction nozzle 55 and the dust conveying pipe 54. The dust and impurities are then filtered by the filter plate 53 installed inside the dust collection box 51. After prolonged use, the filter plate 53 can be removed for cleaning.
