Embodiment 1

[0050] The separation system of the bottle of the waste plastic bottle of the present embodiment, label and cap, as figure 1 As shown, it includes soaking tank 1, stripping mechanism 2, air selection mechanism 3 and selection platform 4 arranged in sequence according to the process, and the soaking pool 1 and stripping mechanism 2 are connected; stripping mechanism 2, wind selection mechanism 3 and selection platform 4 are sequentially arranged Connected through the feeding auger; the tail end of the selection platform 4 is dropped into the crusher 5; the crusher 5 communicates with the beginning of the separation tank 6 through the discharge port 51; the end of the separation tank 6 passes through the plastic particle discharge port 63 It communicates with the plastic particle collection box 66; the separation pool 6 is filled with separation liquid.

[0051] The bottle, label and cap separation system of waste plastic bottles in this embodiment, in the specific use process, ...

Embodiment 2

[0053] The separation system of the bottle of the waste plastic bottle of the present embodiment, label and cap, basic structure is the same as embodiment 1, difference and improvement are: as figure 2 As shown, a rotating cylinder 21 is fixed horizontally inside the peeling mechanism 2, a movable knife 22 is fixed on the outer edge of the rotating cylinder 21, a knife seat 24 is fixed below the rotating cylinder 21, and a knife seat 24 is fixed on the surface of the knife seat 24 to cooperate with the movable knife 22. The fixed knife 23, the gap between the movable knife 22 and the fixed knife 23 forms a knife edge 25, and the knife edge 25 is connected to the bottle collection box 29; 32. The upper end of the roller net cylinder 32 is externally connected to the discharge port of the feeding auger, and the lower end is externally connected to the waste bottle collection and transfer mechanism 37 through the waste bottle discharge pipe 313; one side of the horizontal barrel ...

Embodiment 3

[0063] The separation system of bottles, labels and caps of waste plastic bottles of this embodiment has the same basic structure as that of Embodiment 2, the difference and improvement are: a circulating water pipe 12 is arranged at the bottom of the soaking pool 1, and the circulating water in the soaking pool 1 flows to After the knife edge 25, return to the lower part of the feeding port of the feeding auger, through the flow of water, the bottle body is moved towards the direction of the knife edge, which improves the separation production efficiency; the stripping mechanism 2 is a box structure, and the top of the box is provided with a spray The shower nozzle 26 sprays the blade of the movable knife 22 to keep the blade in a clean state, so as to avoid the remaining mark paper on the blade from affecting the separation efficiency; The air outlet pipe 312 is externally connected to avoid air backflow affecting separation; at the bottom of the air outlet pipe 312, the hori...

Abstract

The invention discloses a separation system for bottle bodies, labels and covers of waste plastic bottles and a machining method of the separation system, and belongs to the technical field of recovery and regeneration of waste plastic bottles. The separation system comprises a soaking pool, a stripping mechanism, an air classification mechanism, a picking platform, a crushing machine and a separation pool which are sequentially arranged according working procedures. The stripping mechanism, the air classification mechanism and the picking platform communicate in sequence through a feeding packing auger. Materials are discharged from the tail end of the picking platform into the crushing machine. The crushing machine communicates with the start end of the separation pool through a discharge outlet. The tail end of the separation pool communicates with a plastic granule collection tank through a plastic granule discharge outlet. The separation pool is filled with separation liquid. The labels on the bottle bodies of the waste plastic bottles are softened after being soaked, stripped through the stripping mechanism and blown away through the air classification mechanism. After being crushed, the covers and the bottle bodies are separated in the separation liquid due to the fact that the densities of the covers and the bottle bodies are different, accordingly, separation of the labels, the bottle bodies and the covers is achieved, and the problems that the labels on the bottle bodies of the waste plastic bottles are not likely to be separated out due to tight sticking and secondary pollution is likely to be caused when a chemical method is adopted for treatment are solved.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastic bottles, in particular to a system for separating bottles, labels and caps of waste plastic bottles and a processing method thereof. Background technique [0002] In modern society, plastic bottles are used in all walks of life due to their advantages such as light weight and low price. Most plastic bottles are generally disposable and thrown away after use. Plastics will not rot if they are buried underground for hundreds, thousands or even tens of thousands of years. Due to the non-natural degradability of plastics, it has become a common phenomenon for human beings. The No. 1 enemy of polluting the environment. [0003] Therefore, it is necessary to recycle plastic bottles or some plastic products, and then process and manufacture them for reuse. Generally, the plastic bottles need to be sorted first, and the classification is carried out for cleaning, delabeling, crushing, so...
