Description

Technical Field

[0001] This utility model relates to the technical field of plastic waste treatment equipment, specifically to an automatic sorting and compression device for plastic waste. Background Technology

[0002] Plastic waste is a general term for plastics that have been used and eventually phased out or replaced in civilian and industrial applications. Plastics are difficult to decompose and often cause large-scale pollution. With the continuous increase in the consumption of plastic products, the amount of waste plastic is also constantly increasing. Improper storage, transportation, processing, and post-processing of these waste plastic raw materials will inevitably damage the environment and endanger public health. A search revealed Chinese patent publication number CN219583313U, which discloses an environmentally friendly plastic pellet sorting device, including a mounting base. A compression spring assembly is installed on the top of the mounting base, and a sorting box is installed on the top of the mounting base via the compression spring assembly. A sorting net and a discharge inclined plate are fixedly installed inside the sorting box. When this technical solution is used, its... The magnetic separator is driven by a motor to rotate and adsorb metal materials for sorting. However, during continuous operation, the surface of the single magnetic separator is eroded and worn due to direct contact with hard metal particles. Over time, the surface roughness of the magnetic separator increases, directly affecting its magnetic separation efficiency and accuracy. In addition, the temperature of the magnetic separator is increased by the scraper used to continuously scrape the material off the surface of the magnetic separator, which also accelerates the aging process of the magnetic blocks, causing the magnetic force to gradually weaken and thus reducing the long-term performance of the equipment. At the same time, the equipment lacks a structure for compressing plastic waste, making the collection, storage and transportation of waste more cumbersome and unable to meet the usage requirements. Therefore, an automatic plastic waste sorting and compression device is proposed to solve the above-mentioned problems. Utility Model Content

[0026] A compression and collection mechanism 8 extending to the right side of the conveyor belt 3 is fixedly installed between the bottoms of the two connecting plates 2. The compression and collection mechanism 8 includes a collection box 81, which is fixedly installed between the bottoms of the two connecting plates 2 and located on the right side of the conveyor belt 3.

The output end of the device is fixedly installed with a push plate that fits against the inner wall of the collection box 81. The bracket improves the stability of the second electric push rod 86. The cooperation between the second electric push rod 86 and the push plate facilitates the discharge of compressed waste from the collection box 81. An extension block 87 is fixedly installed on the right side of the collection box 81. A third electric push rod 88 is rotatably installed at the bottom of the extension block 87. A box door 89 is rotatably installed on the right side of the collection box 81 and fits against it. The output end of the third electric push rod 88 is rotatably connected to the box door 89. This automatic plastic waste sorting and compression device, through the use of the compression collection mechanism 8, uses the first electric push rod 84 to drive the compression plate 85 to compress the waste, effectively reducing the volume of the waste and facilitating storage and transportation. In addition, the coordinated control of the second electric push rod 86, the push plate, the third electric push rod 88, and the box door 89 effectively facilitates the user to push out the compressed plastic waste, further improving the ease of operation of the device.

[0027] In operation, plastic waste enters the pretreatment box 5 through the feed hopper 6. Inside the pretreatment box 5, the crushing rollers rotate under the drive of an auxiliary motor, crushing large pieces of plastic waste into smaller pieces. The crushed waste falls onto the conveyor belt 3 through the discharge port of the pretreatment box 5. The conveyor belt 3, driven by the drive motor 4, transports the pretreated waste to the right. When the waste passes through the sorting mechanism 7, the control motor 76 drives the magnetic separator roller 75 to rotate. The magnetic separator roller 75 adsorbs metal impurities from the waste. When a large amount of metal impurities are adsorbed on the magnetic separator roller 75, the servo motor 73 drives the swing plate 74 to rotate the magnetic separator roller 75. The lower magnetic separator roller 75 alternates with the upper magnetic separator roller 75. The scraper 79 scrapes the metal impurities adsorbed on the magnetic separator 75 into the collection box 78. The user can take out the collection box 78 from the rear to process the metal impurities. After sorting, the waste continues to be conveyed to the right to the guide hopper 82. Since the bottom of the guide hopper 82 is designed to be inclined, the waste can fall smoothly into the collection box 81. When the plastic waste reaches a certain amount, the first electric push rod 84 drives the compression plate 85 to move downward to compress the waste in the collection box 81. When the waste is compressed to a certain extent, the third electric push rod 88 drives the box door 89 to open, and the second electric push rod 86 drives the push plate to move, pushing the compressed waste to the outside of the collection box 81 for discharge.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] In summary, this automatic plastic waste sorting and compression device, through the use of the sorting mechanism 7, employs two magnetic separation rollers 75 for alternating magnetic separation, allowing a single magnetic separation roller 75 to stagnate and cool after a period of use, thus improving the magnetic separation effect and the durability of the equipment. Furthermore, the use of the compression and collection mechanism 8, which utilizes a first electric push rod 84 to drive a compression plate 85 to compress the waste, effectively reduces the volume of the waste, facilitating storage and transportation. In addition, the coordinated control of the second electric push rod 86, the push plate, the third electric push rod 88, and the door 89 effectively facilitates the user in pushing out the compressed plastic waste, further improving the ease of operation and user convenience, and solving the problems mentioned in the background art.
