Description

Technical Field

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

[0002] Some waste bags will be generated during the slicing process of woven bags. Generally, enterprises reuse the waste bags through a granulator. After the woven bags are granulated, the plastic strips are cut. After cutting, there may be particles that do not meet the requirements, such as powder, small particle debris, long strip blocks, etc. Therefore, generally after cutting, it is necessary to screen the cut plastic particles to remove the plastic particles that do not meet the requirements and reuse them.

[0003] To achieve screening of multiple sizes, a multi-stage screening system is usually adopted. This system consists of multiple screens with different pore sizes. The plastic particles pass through each screen from top to bottom in turn. Larger particles are left on the upper screen, while smaller particles continue to fall until they pass through the screen with the corresponding pore size. In this way, particles of different sizes are effectively separated. However, according to the size characteristics of different plastic particles, it is necessary to select a suitable screen hole size to significantly improve the screening efficiency. Some plastic particle screening devices in the prior art are not convenient to change the screen hole size. During the layer-by-layer screening, the time taken for the plastic particles to fall layer by layer is relatively long, and different-sized plastic particles cannot be accurately separated to meet different production requirements. Therefore, a plastic particle screening device is proposed to solve the above problems. Content of the Utility Model

[0021] In this utility model, by tilting the box body 2 and setting the bottom end of the box body 2 in a funnel shape, it is convenient to screen out materials from the right side and the bottom end. By using a vibration motor 9 and a plurality of shock-absorbing legs 6, the box body 2 is continuously shaken up and down. The shock-absorbing legs 6 include telescopic rods, legs, springs, dampers, etc., which are disclosed in the prior art.

The connecting frame 72 is threadedly connected to the threaded rod 73 and is connected to the rear side of the adjusting plate 4 at one end.

[0025] It should be noted that by turning the threaded rod 73, the connecting frame 72 pulls the adjusting plate 4 to move back and forth.

[0026] In an alternative embodiment, two discharge holes are provided on the right side of the box body 2. A discharge pipe is communicated with the bottom end of the box body 2.
