Description

[0001] The utility model relates to the technical field of metal separation, in particular to an automatic metal separator for a vibrating screen. Background Art

[0002] As the consumption of plastic products continues to increase, the amount of waste plastics is also increasing. Plastic recycling refers to the use of a certain recycling process to recycle waste plastics and achieve the purpose of turning waste into treasure. After recycling, waste plastics are recycled and processed to turn them into new plastic products. Since waste plastics usually contain metal substances, waste plastics and metals are mixed together, which affects subsequent processing. Therefore, a metal separator is needed to separate the metal from waste plastics.

[0003] In the process of using, the existing metal separators have gradually exposed their shortcomings. The screening effect of the metal separator is poor. Specifically, the waste plastics and the metals mixed therein are of different sizes. When the small metal is pressed under the large waste plastic, the electromagnetic iron remover in the metal separator cannot adsorb the metal under the waste plastic, or when the small plastic is located above the large metal, the electromagnetic iron remover in the metal separator adsorbs the waste plastic and the metal together, and when waste plastics are added to the metal separator, the distribution of the waste plastics is uneven, and too much waste plastic in some parts will also lead to incomplete screening of the metal therein.

[0057] The waste plastics to be screened are added into the vibration box 15 through the feeding pipe 14, and the waste plastics fall to the top of the sieve plate 12. At the same time, the vibration motor 7 vibrates. With the cooperation of the four elastic support rods 9, the vibration box 15 vibrates, thereby driving the sieve plate 12 and the receiving plate 10 to vibrate. During the vibration of the sieve plate 12, the waste plastics on the sieve plate 12 can be screened.

When the waste plastics move to the suction belt When the waste plastic is below the belt 25, under the action of the magnetic field of the electromagnetic iron remover 29, the metal in the waste plastic is adsorbed to the surface of the suction belt 25. At the same time, the two control motors 33 respectively drive the two driving rollers 23 to rotate, thereby driving the two suction belts 25 to rotate, thereby driving the metal adsorbed on the surface of the suction belt 25 to move. When the metal moves out of the magnetic field range of the electromagnetic iron remover 29, the metal is thrown away. The thrown away metal enters the collection box 36 through the two metal discharge channels 35 respectively. The waste plastic screened on the upper conveyor belt 4 is transported to the lower conveyor belt 2 through the collection channel 3, realizing the function of screening the waste plastic according to the volume size and screening the metal in the screened waste plastic respectively, thereby improving the screening effect of the metal in the waste plastic. At the same time, the two electromagnetic iron removers 29 screen the metal in the waste plastic at the same time, thereby improving the screening efficiency.

[0058] The waste plastics on the sieve plate 12 and the receiving plate 10 can be evenly distributed on the top of the sieve plate 12 and the receiving plate 10 under the vibration of the vibration box 15, and then the waste plastics can be evenly conveyed to the upper conveyor belt 4 and the lower conveyor belt 2, effectively preventing excessive waste plastics in local positions of the upper conveyor belt 4 or the lower conveyor belt 2, and further improving the screening effect of metals in waste plastics.
