[0002] Plastics are widely used in various fields due to their advantages such as easy processing, easy availability, wear resistance, impact resistance, good rigidity, and light weight. With social development, people's pursuit of quality of life is getting higher and higher, which promotes the development of plastic technology. Plastic products are gradually increasing in people's lives, and the output is rising significantly year by year. However, due to the wide variety of plastics and different manufacturing processes, the mixed waste plastics make recycling very difficult. How to quickly and effectively process plastic recycling has become a major problem.

[0003] When recycling plastics, plastic products (such as plastic bottles) are usually crushed into plastic flakes. However, since plastic bottles are usually covered with labels and many bottle caps are also embedded with silicone, the crushed plastic flakes will contain impurities such as labels, silicone, and powder. Therefore, it is necessary to remove these impurities from the plastic flakes. In the existing technology, air classifiers are usually used for screening. However, since the plastic flakes themselves are of different sizes, especially the presence of large pieces, the air classification effect will be seriously affected. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a plastic sheet sorting device to solve the technical problem that the presence of large pieces of sheet material seriously affects the removal of impurities such as label paper, silicone and powder mixed in with plastic sheet material.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a plastic sheet sorting device, comprising:

[0007] A vibrating screen, wherein the vibrating screen has a coarse material outlet, a fine material outlet, and a powder material outlet; and,

[0008] The air separation mechanism includes an air separation shell, an air separation pipe, and a blower. The air separation pipe is fixed inside the air separation shell. One end of the air separation pipe is connected to the fine material outlet. An air inlet is provided on the side wall of the air separation pipe. A first discharge hole is also provided on the side wall of the air separation pipe, which is opposite to the air inlet. The air outlet of the blower is oriented towards the air inlet.

The screen assembly is fixed inside the vibrating box and includes a first screen and a second screen, both fixed inside the vibrating box. The mesh diameter of the first screen is larger than that of the second screen. A first receiving cavity is formed between the first screen and the inner top surface of the vibrating box, communicating with the coarse material outlet. A second receiving cavity is formed between the second screen and the first screen, communicating with the fine material outlet. A third receiving cavity is formed between the second screen and the inner bottom surface of the vibrating box, communicating with the powder outlet. The vibration drive includes a buffer seat and a vibrator. The vibrating box is fixed on the buffer seat, and the vibrator is connected to the vibrating box and used to drive the vibrating box to vibrate.

[0010] In some embodiments, the buffer seat includes a base and an elastic element, one end of the elastic element is fixedly connected to the base, and the other end of the elastic element is fixedly connected to the vibration box.

[0011] In some embodiments, the number of elastic elements is four.

[0012] In some embodiments, the air separation mechanism further includes an air outlet pipe, one end of which is connected to the first discharge hole.

[0013] In some embodiments, a filter element is also installed inside the air outlet pipe, and a second discharge hole is provided on the side wall of the air outlet pipe, the second discharge hole being located between the filter element and the first discharge hole.

[0018] Compared with existing technologies, the beneficial effects of the plastic sheet sorting device provided by this utility model are as follows: During use, the mixture of crushed plastic products is fed into a vibrating screen. Larger plastic sheets are discharged from the coarse material outlet, smaller plastic sheets from the fine material outlet, and powder from the powder outlet. The smaller plastic sheets discharged from the fine material outlet typically contain impurities such as labels, silica gel, and powder. Therefore, the mixture discharged from the fine material outlet is fed into an air separation pipe. When the mixture reaches the air inlet, the blower blows the lighter impurities such as labels, silica gel, and powder out of the first discharge hole, while the heavier plastic sheets are discharged from the other end of the air separation pipe. This achieves the removal of impurities such as labels, silica gel, and powder from the plastic sheets. This utility model separates larger and smaller plastic sheets using a vibrating screen, and then further separates the smaller plastic sheets using an air separation mechanism, avoiding the influence of larger plastic sheets on the air separation process and improving the sorting effect.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem that the presence of large pieces of plastic sheet material severely hinders the removal of impurities such as label paper, silicone, and powder from plastic sheet material, this invention provides a plastic sheet material sorting device that can efficiently remove impurities such as label paper, silicone, and powder from plastic sheet material.

[0030] In one embodiment, please refer to Figure 1 and Figure 2 The screen assembly 12 includes a first screen 121 and a second screen 122, both of which are fixed inside the vibrating box 11. The mesh diameter of the first screen 121 is larger than that of the second screen 122.

[0038] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: In use, the mixture of crushed plastic products is fed into the vibrating screen 1. Larger plastic flakes are discharged from the coarse material outlet 101, smaller plastic flakes are discharged from the fine material outlet 102, and some powder is discharged from the powder outlet 103. The smaller plastic flakes discharged from the fine material outlet 102 usually contain impurities such as label paper, silicone, and powder. Therefore, the mixture discharged from the fine material outlet 102 is fed into the air classifier pipe 22. When the mixture reaches the air inlet 221, the blower 23 blows it out. The airflow blows lighter debris such as labels, silicone, and powder out of the first discharge hole 222 and into the air outlet 24. Due to the obstruction of the filter element 25, the labels and silicone pass through the second discharge hole 241 and fall into the light material pipe 26, finally exiting from the light material outlet 212. The powder passes through the filter element 25 and is finally exited from the powder outlet 213. The heavier plastic sheets are discharged from the other end of the air separation pipe 22 and finally from the positive material outlet 211, thus achieving the removal of debris such as labels, silicone, and powder mixed in with the plastic sheets. This utility model separates the larger plastic sheets from the smaller plastic sheets using the vibrating screen 1, and then the smaller plastic sheets are air-separated by the air separation mechanism 2, avoiding the influence of the larger plastic sheets on the air separation process and improving the separation effect.
