Cap and label removal device for plastic bottles

Abstract

The invention relates to the technical field of waste plastic recycling and processing, in particular to a cap and label removal device for plastic bottles. The device comprises a rack, a cap removalmechanism and a label removal mechanism, wherein the cap removal mechanism is used for conveying the recovered plastic bottles and separating caps from bottle bodies, and the label removal mechanism scrapes labels of the plastic bottle bodies so as to remove the labels. The recovered plastic bottles are transported by a flexible conveying mechanism, and the flexible conveying mechanism can move freely when conveying the bottles with different sizes because internal support components of the flexible transport mechanism are springs; the caps are clamped by cams, the caps and the bottle bodies are separated by a rotating belt after clamping, accordingly, integrity of the bottle bodies is guaranteed, the labels are removed by scrapers moving in two directions and a label removal roller, ,complete separation of the labels is realized, and the influence on subsequent recovery due to partial label adhesion is avoided.

Description

technical field [0001] The invention relates to the technical field of plastic recycling and processing, in particular to a device for removing caps and labels from plastic bottles. Background technique [0002] With the development of industry, the application of plastic products has spread all over the fields of industry, agriculture and daily life. The waste plastic waste generated every day in the world cannot be estimated, but it is obvious that it has a great pressure on the environment. In order to deal with these plastics Garbage, the current method is generally landfill, incineration and so on. However, due to the long natural degradation time of ordinary plastic waste, it generally takes more than a hundred years to degrade, and a large amount of methane and other harmful substances will be produced during the degradation process, so the landfill method will damage the soil; and the incineration method produces Harmful gases, smoke, etc. directly affect the enviro...

AI Technical Summary

Problems solved by technology

This device pushes the plastic bottle forward through the screw propeller. During the process of pushing, the label of the plastic bottle is peeled off through the fixedly installed four-edge stripping knife. Relative movement in one direction, so it is impossible to quickly and completely separate from the label, and the label is discharged by suction. During the suction process, the label is easy to stick to the fan, which will affect the stability of the device.
