Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a plastic waste recycling device. Background Art

[0002] Plastic waste is one of the wastes generated in large quantities in modern society. In order to utilize these wastes more efficiently and environmentally friendly, recycling and reprocessing have become common treatment methods. At present, when recycling plastic waste, it is necessary to first pre-treat the plastic waste, that is, to crush the plastic waste into suitable sizes to facilitate the subsequent processing and reuse of the waste.

[0003] However, as far as the currently existing plastic waste recycling and utilization equipment is concerned, it does not have a cyclic crushing structure when crushing plastic waste. Waste that has been crushed to an appropriate size and waste that does not meet the standard (non-standard means that the plastic waste after crushing does not meet the crushing target size. Generally, the plastic waste that does not meet the standard will be larger, which will not be repeated below) will be discharged separately, and the waste that does not meet the standard needs to be manually poured back into the crushing device for repeated crushing until all the waste is crushed to an appropriate size. This is rather cumbersome. The above steps need to be repeated in the pretreatment process of waste recycling, and the labor intensity of workers is high, the flexibility is poor, and the practicality is not high.

The screening frame 302 rotated to the recycling channel 1013 will automatically vibrate, thereby improving the screening efficiency and screening effect, and also avoiding the clogging of the screen 3024. It is stable and efficient to use. A vibration tension spring 3023 is provided on the top of the track block 3021, and the two ends of the vibration tension spring 3023 are respectively fixedly connected to the track Inside the track block 3021 and inside the screening seat 301, when the screening frame 302 rotates to the recovery channel 1013, the vibration rod 3022 will be resisted and lifted by the bevel of the vibration tooth block 1014, so that the vibration tension spring 3023 is stretched to store energy, and when the vibration rod 3022 leaves the vibration tooth block 1014, the vibration tension spring 3023 contracts and resets to drive the screening frame 302 to fall quickly to complete a single vibration action, so that the vibration rod 3022 triggers the vibration action when passing through any vibration tooth block 1014, so that the screening frame 302 will continue to vibrate when passing through the recovery channel 1013, which is convenient for screening the crushed plastic waste. The design that the spacing between adjacent vibration tooth blocks 1014 is greater than the outer diameter of the vibration rod 3022 makes the vibration action triggering of the screening frame 302 obtained by the vibration rod 3022 stable and extremely stable.

[0034] Specific usage and function of this embodiment: In the present invention, the crushing mechanism 2 can realize the crushing of the plastic waste entering the mounting seat 101. The crushed plastic waste is smaller, which is convenient for subsequent processing. The plastic waste can be poured into the mounting seat 101 through the feeding channel 104 to complete the feeding operation. After being poured into the feeding channel 104, the plastic waste can enter the crushing channel 1011 through the screening chamber 3011 aligned with the feeding channel 104. The driving motor 103 can drive the crushing main roller 201 and the crushing auxiliary roller 202 to rotate synchronously and in opposite directions, so that the plastic waste inside the crushing channel 1011 can be crushed. It is flexible and convenient to use. When the driving motor 103 When rotating, it can drive the screening seat 301 to rotate. When the screening seat 301 rotates, it can drive the gear ring 3012 to drive the crushing main roller 201 to rotate through the driving gear 2011.

The circulation component has the characteristic of selective circulation discharge during discharge, that is, the plastic waste crushed by the crushing mechanism 2 can fall into the screening cavity 3011 of the screening seat 301 through the discharge channel 1012, and the qualified plastic waste can pass through the screen 3024 inside the screening frame 302 and finally be discharged from the recovery channel 1013 The waste plastics that do not meet the standards will be intercepted by the screen 3024 and temporarily stored in the screening chamber 3011. When the screening chamber 3011 is crushed, the screening chamber 3011 can rotate under the drive of the driving motor 103, so that the screening chamber 3011 will also rotate with the screening chamber 301. When the screening chamber 3011 rotates to the top, the waste plastics that do not meet the standards in the screening chamber 3011 can fall into the crushing channel 1011 again under the action of gravity, and be crushed again. The above cycle will not end until all the waste plastics are crushed to a suitable size. No human intervention and control are required. The circulation component has a vibration function when screening the crushed plastic waste. The screening frame 302 will vibrate automatically to improve the screening efficiency and screening effect, and at the same time, it can also avoid the blockage of the screen 3024, which is stable and efficient to use. When the screening frame 302 rotates to the recovery channel 1013, the vibration rod 3022 will be resisted and lifted by the bevel of the vibration tooth block 1014, so that the vibration tension spring 3023 is stretched to store energy.
