[0002] Plastics are polymers made from monomers through addition or condensation polymerization. They are important organic synthetic polymers with a wide range of applications. Common plastic products include plastic bags, plastic buckets, and plastic bottles. Due to the wide application of plastics, the cost of plastic waste is relatively high. However, plastics can be reused, and indiscriminate disposal of plastics will pollute the environment. Therefore, plastic waste is generally recycled.

It includes a collection trough with a feeding box on its left side. A conveyor belt connects the feeding box to the collection trough. A screening cylinder and a crushing hopper are fixed at the bottom of the collection trough. The screening cylinder is connected to the discharge port of the crushing hopper. A slot is formed at the bottom of the collection trough, and a filter screen is installed within the slot. The filter screen filters out fine impurities such as sand and gravel from the recycled plastic, and the screening cylinder, equipped with an electromagnet, screens out metallic impurities from the crushed plastic fragments, thereby separating impurities from the recycled plastic and preventing them from affecting the plastic recycling process.

[0025] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figures 1 to 7As shown, a waste plastic recycling impurity removal device includes a base 1, a processing box 2 installed on the upper surface of the base 1, a conveying mechanism 3 installed on one side of the processing box 2, a crushing mechanism 4 installed inside the processing box 2, a screening frame 5 installed on the upper surface of the base 1 away from the processing box 2, an impurity removal frame 6 slidably connected to the top of the screening frame 5, a screening mechanism 7 installed on the top of one side of the screening frame 5, a metal collection mechanism 8 installed on one side of the top of the screening frame 5, a guide plate 9 installed on the screening frame 5, and a recycling vehicle 10 located below the guide plate 9.

[0027] The screening mechanism 7 includes a drive motor 701 fixedly installed on the top of one side of the screening frame 5. The output end of the drive motor 701 is connected to a turntable 702. A hinge seat 703 is installed on one side of the impurity removal frame 6. A drive rod 704 is rotatably connected between the turntable 702 and the hinge seat 703. A guide rod 705 is installed at the top of the screening frame 5. A slider 706 is slidably connected to the guide rod 705.

[0028] With the above scheme, the drive motor 701 starts, driving the turntable 702 to rotate. The turntable 702 is connected to the hinge seat 703 on one side of the impurity removal frame 6 via the drive rod 704, driving the impurity removal frame 6 to slide back and forth on the guide rod 705. During the reciprocating motion, the plastic particles inside the impurity removal frame 6 are screened, and fine particles and impurities fall through the filter screen 601 at the bottom of the impurity removal frame 6 into the screening frame 5.

[0029] The crushing mechanism 4 includes a second drive motor 401 fixedly installed on one side of the processing box 2. The output end of the second drive motor 401 extends into the interior of the processing box 2 and is connected to a first crushing roller 402. One end of the first crushing roller 402 passes through the inner wall of the processing box 2 and is equipped with a first gear 403. One side of the first crushing roller 402 is rotatably connected to a second crushing roller 404. One end of the second crushing roller 404 is equipped with a second gear 405 that meshes with the first gear 403. A discharge port 406 is installed at the top of the processing box 2.

[0030] With the above scheme, the second drive motor 401 is started, and its output end drives the first crushing roller 402 to rotate. The first crushing roller 402 drives the second crushing roller 404 to rotate synchronously through the meshing transmission of the first gear 403 and the second gear 405. The relative movement between the two crushing rollers crushes the waste plastic into fine particles, which not only improves the crushing efficiency, but also ensures that the crushed plastic particles are of appropriate size, which provides convenience for subsequent processing.

[0031] The conveying mechanism 3 includes a conveying cylinder 301 fixedly installed on the base 1. A feeding pipe 302 is connected between one side of the conveying cylinder 301 and the bottom of the processing box 2. A drive motor 303 is installed at the top of the conveying cylinder 301. The output end of the drive motor 303 extends into the interior of the conveying cylinder 301 and is connected to an auger 304 for transmission. A discharge pipe 305 is connected to the top of one side of the conveying cylinder 301.

[0032] Using the above scheme, the drive motor 303 is started, and its output end drives the auger 304 to rotate inside the conveying cylinder 301, thereby conveying the plastic granules along the conveying cylinder 301 towards the discharge pipe 305. The plastic granules are finally discharged through the discharge pipe 305 and enter the impurity removal frame 6 on the screening frame 5.

[0033] The metal collection mechanism 8 includes a mounting plate 801 fixedly installed on the upper surface of the screening frame 5. An electric push rod 802 is mounted on the mounting plate 801, and an electromagnet 803 is connected to the extended end of the electric push rod 802.

[0034] Through the above scheme, during the screening process, the electric push rod 802 is activated to drive the electromagnet 803 to approach the plastic particles in the screening frame 5. After the electromagnet 803 is energized, it generates magnetism and adsorbs metal impurities during the screening process. When the metal impurities adsorbed on the electromagnet 803 reach a certain amount, the electric push rod 802 retracts, removing the electromagnet 803 and the adsorbed metal impurities out of the screening area for collection and treatment. This not only avoids the waste of metal resources but also reduces the risk of environmental pollution.

[0035] A filter screen 601 is installed at the bottom of the impurity removal frame 6.

[0036] The usage process of this utility model patent is as follows: Open the discharge port 406 at the top of the processing box 2, put the waste plastic to be recycled into the processing box 2, start the second drive motor 401, its output end drives the first crushing roller 402 to rotate. The first crushing roller 402 drives the second crushing roller 404 to rotate synchronously through the meshing transmission of the first gear 403 and the second gear 405. The relative motion between the two crushing rollers crushes the waste plastic into fine particles. Start the third drive motor 303, its output end drives the auger 304 to rotate in the conveying cylinder 301. The crushed plastic particles enter the conveying cylinder 301 through the feeding pipe 302 and are pushed to the discharge pipe 305 by the auger 304. The plastic particles are discharged from the discharge pipe 305 and fall into the impurity removal frame 6 on the screening frame 5. Start the first drive motor 701, its output end drives the turntable 702. Rotating, the turntable 702 is connected to the hinge seat 703 on one side of the impurity removal frame 6 via the drive rod 704, driving the impurity removal frame 6 to slide back and forth on the guide rod 705. The plastic particles are screened in the impurity removal frame 6, and fine particles and impurities fall into the screening frame 5 through the filter screen 601. During the screening process, the electric push rod 802 is activated, which drives the electromagnet 803 to approach the plastic particles in the screening frame 5. After the electromagnet 803 is energized, it generates magnetism and adsorbs metal impurities. When the metal impurities adsorbed on the electromagnet 803 reach a certain amount, the electric push rod 802 retracts, removing the electromagnet 803 and the adsorbed metal impurities out of the screening area for collection. After screening and impurity removal, the plastic particles are guided by the guide plate 9 and fall into the recycling cart 10 below. When the recycling cart 10 is full, it is removed from the device for further processing.
