Description

Technical Field

[0001] The invention relates to the technical field of separation equipment, in particular to adjustable metal separation equipment and method for PET bottle flakes. Background Art

[0002] PET bottle refers to a bottle made of PET plastic material. PET plastic material is a polymer produced by the combination of terephthalic acid and ethylene glycol. PET plastic has the characteristics of light weight, high transparency, impact resistance and not easy to break. It can also block carbon dioxide gas to keep the soda. PET material can be recycled using waste PET bottles and has a high recycling value.

[0003] For example, the prior art CN109877998A proposes a metal separation device for PET bottle flakes, comprising a frame, a metal impurity collection box, a PET bottle flake collection box, a V-shaped plate, a lifting mechanism, a magnet, a mounting plate, a scraping mechanism, a separation box, a second motor and a first rotating shaft; by arranging the metal impurity collection box on both sides of the PET bottle flake collection box, it is possible to prevent the charged PET bottle flakes to be separated from falling into the metal impurity collection box, so that the metal impurities in the PET bottle flakes can be separated at one time.

[0004] However, the above equipment still has certain defects in practical application. When used, the equipment uses a magnet to recover iron in PET materials. However, in the application of PET bottles, there are not only iron-containing bottle caps but also some aluminum bottle caps. The existing technology can only separate the iron after the bottle is crushed, but cannot separate the aluminum, resulting in certain limitations in application. At the same time, when the PET bottle is recycled, the existing technology crushes the entire bottle together with the bottle cap when crushing the PET bottle. However, the bottle body of the PET bottle does not contain metal and does not need to be metal-removed. The existing technology crushes the bottle head part and the bottle body part together for processing, which will greatly increase the separation processing amount, resulting in certain defects in application. For this reason, we provide an adjustable PET bottle flake metal separation device and method to solve the above-mentioned problems. Summary of the invention

At the same time, the rotation of the main shaft 602 can also drive the third belt 606 and the third pulley 607 to rotate, and the rotation of the third pulley 607 can drive the horizontal shaft 220 to rotate.

[0057] The working principle of the present invention is as follows: when working, the driving motor 109 is first started, the driving motor 109 drives the rotating shaft 107, the rotating shaft 107 rotates to drive the worm 604 to rotate, the worm 604 drives the worm wheel 605, the worm wheel 605 drives the second pulley 603 and the second belt 601, and then drives the crushing roller 501 to rotate, and at the same time, the rotation of the main shaft 602 can also drive the third belt 606 and the third pulley 607 to rotate, and the rotation of the third pulley 607 can drive the horizontal shaft 220 to rotate, and then the PET bottle is placed between the two discharge plates 450, and then the conveying rod 440 is driven to vibrate through the direct vibration 410 to deliver the PET bottle. When the PET bottle reaches the feed box 102, when it hits the micro switch 463, the first cylinder 465 drives the upper cutting knife 466 to move downward. When the upper cutting knife 466 moves, the second gear 469 and the rack 468 on both sides cooperate with each other to make the lower cutting knife 466 move upward. The two relatively moving cutting knives 466 can cut the PET bottle head. The cut bottle head will fall into the feed box 102, and the bottle body will push the bottle body under the action of the second cylinder 467 and the push block, so that the bottle body is deformed and ejected from the gap between the conveying rods 440. The ejected bottle body falls to the guide cover 106 and then enters the bottle body collection box 1 03, and the bottle heads falling into the feed box 102 are collected. The relative rotation of the two crushing rollers 501 can realize the crushing of the bottle heads. The crushed bottle heads fall into the striking box 105. At the same time, the rotation of the rotating shaft 107 can drive the striking piece 108 to operate. The striking piece 108 rotates to continuously hit the crushed fragments onto the inner wall of 1, so that the fragments are separated and independent of each other, and the PET material, iron and aluminum are prevented from sticking together. At the same time, the rotation of the fourth gear 503 can drive the first gear 301 to rotate, and the rotation of the first gear 301 drives the connecting rod 302 to move, and the movement of the connecting rod 302 drives the discharge gate 303 to move up and down. The discharge gate plate 303 moves up and down to realize intermittent discharge of the striking box 105. At the same time, the rotation of the drive roller 230 can drive the first conveyor belt 240 to operate. The operation of the first conveyor belt 240 can drive the fallen crushed material to be transported to the PET collecting box 260. During the transportation process, the iron in the crushed material is removed by the iron removal mechanism 210. When the crushed material passes through the eddy current magnetic roller 280, the eddy current inside the aluminum sheet generates an opposite magnetic field, and the repulsive force of the magnetic field leaps in the conveying direction and enters the aluminum collection box 270, while the PET material will enter the PET collection box 260 under the action of gravity, thereby realizing the separation of metals.
