Plastic waste recycling device

Abstract

The present invention provides a plastic waste recycling device, which relates to the field of plastic recycling and includes: a circulation component, which is composed of a crushing mechanism and a screening mechanism, and a mounting seat with a double feeding structure. First, plastic waste is manually added to the interior of the mounting seat through a feeding channel for crushing processing, and second, the circulation component can reintroduce the crushed and substandard plastic waste into the interior of the crushing mechanism for crushing again, until the plastic waste is crushed to a suitable size and then discharged from the interior of the mounting seat for people to collect. No human control, operation and intervention are required, which reduces labor intensity and simplifies the waste processing process. It solves the problem that the existing plastic waste recycling device does not have a circulation crushing structure when crushing plastic waste, and needs to manually pour the substandard waste back into the crushing device for repeated crushing, which is relatively cumbersome.

Description

Technical Field

[0001] The present 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 pre-treat the plastic waste first, that is, to crush the plastic waste into a suitable size to facilitate the subsequent processing and reuse of the waste.

[0003] However, as far as the currently available 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 described in detail below) will be discharged separately. The waste that does not meet the standard needs to be poured manually 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, which results in high labor intensity for workers, poor flexibility, and low practicality.

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 push rod 3022 will be resisted and lifted by the oblique edge of the vibrating tooth block 1014, so that the vibration tension spring 3023 is stretched and energy is stored. When the vibration push rod 3022 leaves the vibrating tooth block 1014, the vibration tension spring 3023 contracts and resets, driving the screening frame 302 to fall quickly to complete a single vibration action, so that the vibration push rod 3022 triggers the vibration action when passing through any vibrating 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 distance between adjacent vibrating tooth blocks 1014 is greater than the outer diameter of the vibration push rod 3022 makes the vibration action of the screening frame 302 obtained by the vibration push rod 3022 stable and extremely stable.

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 the plastic waste is poured into the feeding channel 104, it can enter the crushing channel 1011 through the screening cavity 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 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 characteristics of selective circulation discharge when discharging, 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 collected and recycled by people, while the waste plastics that do not meet the standards will be intercepted by the screen 3024 and temporarily stored in the screening chamber 3011. Since the screening seat 301 can rotate under the drive of the drive motor 103 during crushing, the screening chamber 3011 will also rotate with the screening seat 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 circulation component has a vibration function when screening the crushed plastic waste. It rotates to the recycling channel 1013. The screening frame 302 will vibrate automatically, which improves the screening efficiency and screening effect, and can also avoid the clogging of the screen 3024. It is stable and efficient to use. When the screening frame 302 rotates to the recycling channel 1013, the vibrating rod 3022 will be resisted and lifted by the oblique edge of the vibrating tooth block 1014, so that the vibration tension spring 3023 is stretched and energy is stored. When the vibrating rod 3022 leaves the vibrating 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 vibrating rod 3022 triggers the vibration action when passing through any vibrating tooth block 1014, so that the screening frame 302 will continue to vibrate when passing through the recycling channel 1013, which is convenient for screening the crushed plastic waste.The design that the distance between adjacent vibrating tooth blocks 1014 is larger than the outer diameter of the vibrating rod 3022 makes the vibration action of the screening frame 302 obtained by the vibrating rod 3022 trigger stable.
