[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-4 In this embodiment, a plastic granulation vibrating screening device is provided, including a frame 1. The width of the upper and lower ends of the frame 1 is smaller than the width in the middle of the frame 1. The upper end of the frame 1 is provided with an opening, and a screen 7 is installed inside the opening. A screen 8 is installed in the middle of the frame 1. When the width of the two ends of the connecting net 82 is the same as that of the screen 7, the screening area of ​​the connecting net 82 and the bottom net 81 is greater than the screening area of ​​the screen 7. The connecting net 82 can be adjusted outward or inward.

[0024] Screen 8 includes a bottom screen 81, with connecting screens 82 rotatably connected to both sides of the bottom screen 81. A top screen 83 is rotatably connected to one end of each connecting screen 82. One end of the top screen 83 passes through both sides of the frame 1. Connecting seats 9 are fixedly connected to both sides of the frame 1. A connecting seat 11 is installed on the side of the top screen 83 outside the frame 1. A telescopic rod 10 connects the connecting seat 9 and the connecting seat 11. By extending or shortening the telescopic rod 10, the connecting seat 11 can be moved outward or inward, thereby causing the top screen 83 to move inward or outward from the frame 1, thus adjusting the tilt angle of the internal connecting screen 82.

[0025] In this embodiment, specifically, the frame 1 is tilted as a whole, with an opening at one end and a closed end at the other. The horizontal height of the open end of the frame 1 is lower than the horizontal height of the closed end. This ensures that the plastic particles slide down the screen towards the open end.

[0026] In this embodiment, specifically, mounting frames 5 are fixedly connected to both sides of the frame 1, and vibration motors 6 are symmetrically installed at both ends of the mounting frames 5. The vibration motors 6 drive the mounting frames 5 to vibrate, which in turn drives the frame 1 to vibrate, increasing the screening efficiency.

[0027] In this embodiment, specifically, support seats 2 are fixedly installed on both sides of the frame 1 below the top net 83. Springs 4 are connected below the support seats 2, and support feet 3 are connected below the springs 4. The support feet 3, springs 4, and support seats 2 provide elastic support to the frame 1, ensuring that the frame 1 can vibrate.

[0028] In this embodiment, specifically, gaps are provided on both sides of the frame 1, and the top mesh 83 passes through the gaps on both sides of the frame 1. Brushes are installed on both sides of the frame 1 above the gaps, with the lower ends of the brushes located on the top mesh 83. The brushes block the gaps, reducing the likelihood of plastic particles inside the frame being ejected from the gaps where the top mesh 83 passes through the frame 1.

[0029] In this embodiment, specifically, the width of screen 7 is smaller than the width of screen 8.

[0030] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
