Problems solved by technology

[0007] In the prior art, there are waste plastic bottle labels that are not completely peeled off, and the residual labels on the bottle body will cause adverse effects on the post-processing crushing. After the waste plastic bottle body is broken, the manual separation of the bottle body and the bottle cap is time-consuming and laborious. After separation, the plastic Due to the problems of incomplete drying, poor efficiency, and high cost, the present invention provides a post-processing system for waste plastic bottle caps and bottles

Embodiment 1

[0041] The post-processing system of the waste plastic bottle cap bottle of the present embodiment demarking, such as figure 1 As shown, it includes the first feeding auger, the selection platform 2, the crusher 3, the separation tank 4, the plastic collection box 6, the second feeding auger, the dehydration device 7 and the packaging mechanism 8 arranged in sequence according to the process. The blanking opening at the upper end of a feeding auger is facing the beginning of the selection platform 2, and the tail end of the selection platform 2 is fed into the crusher 3; The platform 22; the crusher 3 communicates with the beginning of the separation tank 4 through the discharge port 31; the end of the separation tank 4 communicates with the plastic pellet collection box 6 through the plastic pellet discharge port 43; the separation tank 4 is filled with Separation liquid; the plastic particle collection box 6 communicates with the dehydration device 7 through the second feedi...

Embodiment 2

[0044] The basic structure of the waste plastic bottle cap bottle removal post-processing system of this embodiment is the same as that of Embodiment 1, the difference and improvement are: the dehydration device 7 is a hot air channel, and there is a horizontal auger in the channel, and the temperature of the hot air is 60-80 °C ;

[0045] The production process of the waste plastic bottle cap bottle delabeling post-processing system of the present embodiment, the steps are:

[0046] A. Loading selection: The waste plastic bottle body separated from the bottle and the label is lifted to the top of the selection platform through the first feeding auger, and dropped to the surface of the horizontal conveyor belt 21 through the discharge port, and the operator walks on the platform. On 22, the waste plastic bottle body with residual label on the horizontal conveyer belt 21 is selected;

[0047] B. Crushing: Transfer the selected waste plastic bottle body to the crusher 3 for cru...

Embodiment 3

[0053] The post-processing system for waste plastic bottle caps and bottles in this embodiment has the same basic structure as that in Embodiment 1. The difference and improvement is that a defective product collection box 23 is placed on the walking platform 22 to facilitate the collection of bottles with residual labels. After the defective product is recovered, it is returned to the furnace for processing; Figure 5 As shown, the end of the separation tank 4 has an overflow port 44, and the overflow port 44 is connected to the bottle cap collection box 5; because the composition of the bottle cap is LD-PE, its density is less than water, so it floats on the water surface and passes through the overflow port. The port 44 overflows it into the bottle cap collection box 5 and carries out subsequent dehydration treatment after being collected; the dehydration device 7 includes a discharge switch 75 at the discharge port at the bottom of the oven 70 and the oven 70; the packaging...

Abstract

The invention discloses a waste plastic bottle cap and body label removing aftertreatment system, and belongs to the technical field of waste plastic bottle recycling. The waste plastic bottle cap and body label removing aftertreatment system comprises a first feeding auger, a picking platform, a crusher, a separating pond, a plastic pellet collecting box, a second feeding auger, a dewatering device and a packaging mechanism which are sequentially arrayed according to the working procedures. A material falling opening in the upper end of the first feeding auger directly faces the starting end of the picking platform, and a material at the tail end of the picking platform falls off into the crusher. The crusher communicates with the starting end of the separating pond through a discharging outlet. The tail end of the separating pond communicates with the plastic pellet collecting box through a plastic pellet discharging outlet. The separating pond is filled with separating fluid. The plastic pellet collecting box communicates with the dewatering device through the second feeding auger. The discharging end of the dewatering device is then connected with the packaging mechanism. Plastic pellets of a bottle body are collected into the plastic pellet collecting box in a concentrated mode and then are treated through the dewatering device, so that recycling of a waste plastic bottle is facilitated. The technical problems that waste plastic bottle cap and body label removing is low in aftertreatment efficiency and high in cost in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastic bottles, in particular to a post-treatment system for waste plastic bottle caps and bottles. 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, it is first necessary to classify plastic bottles, and perform cleaning, delabeling, selection, crushing, sorting, drying and other processing procedures to make...
