[0022] Example

[0023] like Figure 1-4 As shown, a vibrating screening device for processing plastic raw materials proposed in one embodiment of the utility model comprises a screening frame 1 and a screening assembly 7. The vibrating screening device for processing plastic raw materials designed in this scheme can realize convenient regulation of the screening size, meet the diversified screening use requirements, and can be conveniently cleaned and used when the material jamming problem occurs, thereby improving the use effect. The two ends of the screening frame 1 are rotatably connected with supporting legs 2, and a plurality of screening assemblies 7 are arranged on the screening frame 1 at equal intervals. The screening assembly 7 is composed of a bidirectional screw rod 8, a knob 9 and a blocking member 10, and the double The two-way screw rod 8 is symmetrically arranged, and both ends of the two-way screw rod 8 are fixedly connected with knobs 9. The two-way screw rod 8 is matched with a plurality of blocking members 10. The device is electrically connected to an external control device through a conductive line, and the operation state of the device is controlled by the external control device. When the device is used to vibrate and screen the plastic raw materials, the vibrator 3 is operated to make the screening frame 1 vibrate and screen for use, and then according to the size of the required screening, the screening diameters of the plurality of screening components 7 are reduced and adjusted in turn from top to bottom. Through the design of the screening component 7, the two-way The blocking member 10 at the center of the screw rod 8 is connected to the bidirectional screw rod 8 by limited rotation and will not be displaced. The blocking members 10 on both sides of the blocking member 10 are respectively threadedly connected to the bidirectional screw rod 8, and the pitch of the thread of the bidirectional screw rod 8 decreases from the center to the two ends. Therefore, when the knob 9 is turned to rotate the bidirectional screw rod 8, the blocking members 10 threadedly connected to the bidirectional screw rod 8 can be slidably adjusted in the widened frame 4, and the spacing can be kept gradually increasing or decreasing, so as to meet the screening of plastic materials of different sizes. To improve the effect of diversified screening, when the blocking member 10 is stuck with material, the distance between the blocking members 10 can be increased by rotating and adjusting the bidirectional screw rod 8, so that the stuck plastic raw materials can fall down, which meets the needs of convenient blockage clearing.

Rotating holes 5 are provided at both ends of the widened frames 4. A discharge port 6 is provided on the screening frame 1 at the upper edge of the widened frame 4 at the position of the lower end leg 2. The design of the screening frame 1 meets the use requirements and ensures the overall connection and use.
