[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 One embodiment of this utility model is a plastic recycling particle size screening device, which includes a housing 1. The top of the outer wall of the housing 1 is fixedly connected to a feed inlet 3. The plastic to be screened is poured into the interior of the housing 1 through the feed inlet 3. The bottom outer wall of the housing 1 is fixedly connected to a waste bin 5. The inner wall of the waste bin 5 is provided with a compression component 4.

[0033] Reference Figure 2 and Figure 3 The outer wall of the housing 1 is provided with a vibration assembly 2, which includes a motor 21. The motor 21 is fixedly connected to the left outer wall of the housing 1. A bracket is provided outside the motor 21 to support it. An elliptical block 22 is rotatably connected to the left outer wall of the housing 1. The bottom end of the outer wall of the elliptical block 22 contacts the top end of the outer wall of the contact plate 23. The contact between the two causes the contact plate 23 to be squeezed by the rotation of the elliptical block 22, which in turn causes the connecting rod 26 to descend synchronously. The output shaft of the motor 21 is fixedly connected to the elliptical block 22. A fixing plate 25 is fixedly connected to the left outer wall of the housing 1. The top end of the outer wall of the fixing plate 25 is elastically connected to the contact plate 23 through a limiting spring 24. One end of the limiting spring 24 is fixedly connected to the surface of the fixing plate 25, and the other end of the limiting spring 24 is fixedly connected to the contact plate 23. The limiting spring 24 is fixedly connected to the bottom end of the outer wall of the contact plate 23. Its function is to automatically reset the position of the contact plate 23 after it is squeezed by the rotation of the elliptical block 22. The contact plate 23 is slidably connected to the outer wall of the left side of the housing 1. A connecting rod 26 is fixedly connected to the bottom end of the outer wall of the contact plate 23. Multiple sets of contact plates 23 are fixedly connected to the surface of the connecting rod 26 and correspond to the filter plate 6. A hinge rod a28 is hinged at the center of the bottom end of the contact plate 23. When the contact plate 23 is squeezed by the rotation of the elliptical block 22 and descends, the hinge rod a28 will push the sliding rod 29 to move on the inner wall of the housing 1. This causes the filter plate 6, which is detachably installed on the surface of the sliding rod 29, to swing laterally left and right on the inner wall of the housing 1, thereby preventing the plastic from accumulating moisture and failing to filter and screen it sufficiently.

[0034] Reference Figure 2 and Figure 3A sliding rod 29 is hinged to the end of the hinge rod a28 away from the contact plate 23. The sliding rod 29 passes through and is slidably connected to the inner wall of the left side of the housing 1. An installation groove is provided on the surface of the housing 1. A connecting block 27 is slidably connected to the inner wall of the installation groove of the housing 1. A through slot is provided on the inner side of the connecting block 27, which corresponds to the outer wall of the sliding rod 29. This allows the filter plate 6 to be pulled outward from the outer wall of the sliding rod 29. The filter plate 6 is provided in three sets, and the three sets of filter plates 6 have different pore sizes, so that different sizes of plastics can be filtered in stages. The filter plate 6 is slidably connected to the inner wall of the installation groove. The connecting block 27 is detachably installed on the sliding rod 29 through a limiting component. The filter plate 6 is fixedly connected to the outer wall of the connecting block 27.

[0035] Reference Figure 1 and Figure 4 The waste bin 5 is equipped with a discharge door 7. By opening the discharge door 7, the waste and dust that have been completely filtered and screened from the plastic inside the waste bin 5 can be discharged outwards. The compression assembly 4 includes a handle 41, which is slidably connected to the top of the inner wall of the waste bin 5. One end of the connecting spring 43 is fixedly connected to the top of the outer wall of the compression plate 44, and the other end of the connecting spring 43 is fixedly connected to the top of the inner wall of the waste bin 5. The function of the connecting spring 43 is to automatically reset the position of the compression plate 44 after the hinge rod b42 pushes it down. 44 is slidably connected to the inner wall of the waste bin 5. The bottom end of the outer wall of the handle 41 is hinged to a hinge rod b42. The end of the hinge rod b42 away from the handle 41 is hinged to a compression plate 44. The surface of the handle 41 is provided with a handle. By pulling the handle 41, the corresponding compression plate 44 can be pushed down on the inner wall of the waste bin 5 through the hinge rod b42 to compress the waste after plastic filtration inside the waste bin 5, thereby reducing the internal space occupied by the waste bin 5. The compression plate 44 is elastically connected to the top of the inner wall of the waste bin 5 through a connecting spring 43.

[0036] Reference Figure 3The limiting component includes a semicircular block 211, which is elastically connected to the inner wall of the sliding rod 29 via a return spring 210. One end of the return spring 210 is fixedly connected to the bottom end of the inner wall of the sliding rod 29, and the other end is fixedly connected to the bottom end of the outer wall of the semicircular block 211. The function of the return spring 210 is to automatically reset the position of the arc surface at the top of the semicircular block 211 after it has been squeezed and moved. The semicircular block 211 is slidably connected to the inner wall of the sliding rod 29. A guide groove is provided on the surface of the connecting block 27, and the outer wall of the sliding rod 29 contacts the inner wall of the guide groove. The sliding rod 29 is fitted into the inner wall of the connecting block 27. The guide groove allows the connecting block 27 to be pulled out laterally from the surface of the sliding rod 29, thereby allowing the filter plate 6 connected to the outside of the connecting block 27 to be replaced. The surface of the guide groove of the connecting block 27 is provided with a slot, and the semi-circular block 211 engages with the inner wall of the slot. The engagement between the two allows the connecting block 27 to drive the filter plate 6 to be inserted longitudinally into the outer wall of the sliding rod 29, and to press the arc surface of the semi-circular block 211 to move it on the inner wall of the sliding rod 29. At the same time, when the semi-circular block 211 moves with the sliding rod 29, it will also drive the connecting block 27 and the filter plate 6 to shake left and right, thereby making the filtration and screening efficiency of plastic higher.

[0037] Working principle: The output shaft of motor 21 is fixedly connected to elliptical block 22. The rotation of elliptical block 22 squeezes contact plate 23. When contact plate 23 is squeezed by the rotation of elliptical block 22 and descends, hinge rod a28 pushes sliding rod 29 to move on the inner wall of housing 1. This causes the filter plate 6, which is detachably mounted on the surface of sliding rod 29, to swing laterally left and right on the inner wall of housing 1, preventing the plastic from accumulating moisture and failing to filter it sufficiently. Connecting block 27 is slidably connected to the inner wall of the mounting groove of housing 1. The inner side of connecting block 27 has a through slot, which corresponds to the outer wall of sliding rod 29, so that the filter plate 6 can be pulled outward from the outer wall of sliding rod 29. The filter plate 6 is provided in three sets, and the three sets of filter plates 6 have different pore sizes, which can filter plastics of different sizes in stages.

[0038] The surface of the connecting block 27 is provided with a guide groove, and the outer wall of the sliding rod 29 contacts the inner wall of the guide groove, so that the connecting block 27 can be pulled out laterally from the surface of the sliding rod 29, thereby replacing the filter plate 6 connected to the outside of the connecting block 27. The surface of the guide groove of the connecting block 27 is provided with a slot, and the semi-circular block 211 engages with the inner wall of the slot, so that the connecting block 27 can drive the filter plate 6 to be inserted longitudinally into the outer wall of the sliding rod 29, and squeeze the arc surface of the semi-circular block 211 to make it move on the inner wall of the sliding rod 29. At the same time, when the semi-circular block 211 moves with the sliding rod 29, it will also drive the connecting block 27 and the filter plate 6 to shake left and right, thereby improving the filtration and screening efficiency of plastic.

[0039] By pulling the handle 41, the corresponding compression plate 44 can be pushed down on the inner wall of the waste bin 5 synchronously through the hinge rod b42, compressing the waste after plastic filtration inside the waste bin 5, thereby reducing the internal space occupied by the waste bin 5. One end of the connecting spring 43 is fixedly connected to the top of the outer wall of the compression plate 44, and the other end is fixedly connected to the top of the inner wall of the waste bin 5, so that the position of the compression plate 44 after the hinge rod b42 pushes it down is automatically reset.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
