[0002] Polyethylene (PE) is one of the five major synthetic resins and is the variety with the largest production capacity and the largest import volume among synthetic resins in China. Polyethylene is mainly divided into three categories: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE). Polyethylene has excellent corrosion resistance and electrical insulation (especially high-frequency insulation), can be chlorinated, irradiated and modified, and can be reinforced with glass fibers. High-density polyethylene has a high melting point, rigidity, hardness and strength, low water absorption, and good electrical properties and radiation resistance.

[0028] Refer to Figures 1-5 , a high-efficiency multi-level screening device for polyethylene plastic particles, including a main body component 1; the main body component 1 includes a box body 11, the top of which is hinged with a sealing cover 12; a rotating door 13, hinged to the front surface of the box body 11, and three are provided; a screening component 2 is provided on the box body 11, and the screening component 2 includes: a rod body 21 inserted into the box body 11; a first sieve plate 22 provided on the rod body 21; a second sieve plate 23 provided on the rod body 21; a slide bar 24 fixedly connected to the bottom of the box body 11 and evenly provided with a plurality of; a slide plate 25 fixedly connected to the bottom end of the rod body 21 and slidably connected to the outer side wall of the slide bar 24; a fixed plate 26, a second spring 4 is fixedly connected to the bottom end of each slide bar 24; a vibration motor 27 fixedly connected to the bottom of the slide plate 25; a second spring 4 is provided on each fixed plate 26, and both ends of each second spring 4 are respectively fixedly connected to the bottom of the slide plate 25 and the top of the fixed plate 26.

[0029] When ready for use, the operator places the box body 11 at the designated position, then opens the sealing cover 12, puts polyethylene plastic particles into the box body 11. Subsequently, the operator turns on the vibration motor 27. The vibration motor 27 drives the sliding plate 25 to vibrate up and down on the sliding rod 24 and is limited by the fixing plate 26. The movement of the sliding plate 25 drives the rod body 21 to move up and down, so that the rod body 21 drives the first sieve plate 22 and the second sieve plate 23 to vibrate simultaneously. Through the first sieve plate 22 and the second sieve plate 23 with different sieve holes, the separated plastic particles and impurities are screened out, and the polyethylene plastic particles of different sizes are screened. After the screening is completed, the operator collects the screened polyethylene plastic particles through a plurality of rotating doors 13, thereby improving the practicability of the device; A second spring 4 is provided on each fixing plate 26. When the sliding plate 25 moves, it drives a plurality of second springs 4 to expand and contract simultaneously. Through the second spring 4, the vibration effect of the device can be increased, thereby improving the screening efficiency of the device.

[0030] Embodiment 2

[0031] Refer to Figures 1-5 , the function of disassembly is added on the basis of Embodiment 1;

[0032] A disassembly component 3 is provided on the box body 11. The disassembly component 3 includes: mounting blocks 31, which are arranged on the outer side wall of the rod body 21 and there are two of them; limiting blocks 32, and limiting blocks 32 are symmetrically arranged inside each mounting block 31; first springs 33, and first springs 33 are arranged on the outer side wall of each limiting block 32; pulling plates 34, and a pulling plate 34 is fixedly connected to the top of each limiting block 32; guide rail covers 35, and guide rail covers 35 are arranged on the outer side wall of each pulling plate 34; fixing blocks 36, and fixing blocks 36 are penetrated through the first sieve plate 22 and the second sieve plate 23; A positioning plate 7 is fixedly connected to the bottom of each mounting block 31; a protective cover 5 is hinged to the top of each mounting block 31; a telescopic rod 6 is fixedly connected to the outer side wall of each limiting block 32.

[0033] After use, the operator pulls the two pull plates 34 on one side mounting block 31, causing the pull plates 34 to drive the limit blocks 32 out of the fixing blocks 36 on the first sieve plate 22 or the second sieve plate 23 and compressing the first spring 33, thereby canceling the limit on the first sieve plate 22 or the second sieve plate 23, facilitating the operator to disassemble, repair or replace the first sieve plate 22 or the second sieve plate 23. At the same time, when the pull plates 34 move, they drive the guide rail cover 35 to move simultaneously, preventing polyethylene plastic particles from entering the inside of the mounting block 31 and causing blockage inside, thereby improving the practicality of the device; a positioning plate 7 is fixedly connected to the bottom of each mounting block 31. When the operator installs the first sieve plate 22 or the second sieve plate 23, after pulling the pull plates 34, the operator drives the first sieve plate 22 or the second sieve plate 23 to make the fixing blocks 36 thereon close to the positioning plate 7. At this time, the limit grooves on the fixing blocks 36 are aligned with the limit blocks 32. Then the operator can release the pull plates 34, and the limit blocks 32 can be automatically ejected into the limit grooves by the first spring 33, preventing the operator from being inconvenient to view the position of the limit grooves and thus being inconvenient to install, thereby improving the convenience of the device; a protective cover 5 is hinged to the top of each mounting block 31. The protective cover 5 can cover the pull plates 34 inside, preventing the polyethylene plastic particles from colliding with the pull plates 34 when moving, resulting in the device not being firmly fixed, thereby improving the stability of the device; a telescopic rod 6 is fixedly connected to the outer side wall of each limit block 32. When the limit blocks 32 move, they drive the telescopic rods 6 to move simultaneously. The telescopic rods 6 can now the moving direction of the limit blocks 32, preventing the limit blocks 32 from being skewed under the elastic force of the first spring 33 and getting stuck inside the mounting block 31, thereby improving the safety of the device.
