Description

Plastic waste label separation device and recycling waste collection device having the same {APPARATUS FOR SEPARATING LABEL OF PLASTIC WASTE AND COLLECTION APPARATUS FOR RECYCLABLE WASTE HAVING THE SAME}

The present invention relates to a plastic waste label separation device, and more particularly, to a plastic waste label separation device capable of efficiently separating a label attached to the plastic waste, and a recycling waste collection device having the same.

In most countries, metal cans, aluminum cans, glass bottles, and plastics are classified as recycled waste, and they are regulated to be recycled. Wastes discharged from homes or factories are generally collected at a garbage collection point and recycled after being sorted by material such as metal cans, aluminum cans, glass bottles, and plastics.

In particular, the use of various plastic containers is increasing year by year because they are superior to glass or metal containers in fracture resistance, light weight, and transparency. In addition, due to its various sizes, it is used in large quantities from small to large, and the proportion of recycled waste is increasing.

In general, a label indicating the product's trademark, instruction manual, and information is attached to a plastic container. The label is usually made of a resin film such as polypropylene or vinyl chloride, which is different from the material of the plastic container. These labels are adhered to the outer surface of the plastic container with an adhesive and then firmly adhered to the plastic container through a thermo-pressurization method.

In order for plastic waste such as plastic containers to be recycled, the label attached to the plastic waste must be separated. This is because, in the process of recycling plastic waste, if the label is melted together with the plastic waste, the quality of the recycled plastic product is rapidly deteriorated. Therefore, in order to recycle plastic waste, the operation of separating the label from the plastic waste must be performed before the plastic waste is shredded.

However, since the label is firmly attached to the plastic waste through an adhesive, it is not easy to separate the label from the plastic waste. Accordingly, the quality of recycled plastic products is deteriorated due to labels attached to plastic waste, and problems in which plastic waste cannot be recycled even after separate collection and must be disposed of are frequently occurring.

The transfer screw 180 rotates by receiving a rotational force from the transfer screw driver 183. As the conveying screw 180 rotates, the label sucked into the label conveying path 172 may be forcibly conveyed to the label outlet 173 along the label conveying spiral guide 182 of the conveying screw 180.

When the suction force generated by the suction force generating unit 177 acts strongly to the label discharge port 173, a problem may occur in that the label is not smoothly discharged from the label discharge port 173. In order to prevent this problem, the label inhaler 170 has a structure in which the suction force does not act as much as possible at the label outlet 173. That is, the label conveying path 172 of the label inhaler 170 has a width Wc2 at a portion connected to the label outlet 173 that is smaller than the width Wc1 at a portion connected to the air inlet 174 And, a certain section from the middle part of the label transfer path 172 to the part connected to the label discharge port 173 is made of a size slightly larger than the width of the transfer screw 180. When the label transfer path 172 is in this form, interference between the label discharge guide 171 and the transfer screw 180 at the downstream portion from the middle portion of the label transfer path 172 to the portion connected to the label discharge port 173 is prevented. While avoiding, it is possible to increase the air resistance by the transfer screw 180. In this way, in the downstream part of the label conveying path 172, the conveying screw 180 obstructs the air flow, so that the suction force of the suction force generating part 177 acts weakly, and the label is transferred to the label outlet 173 by the conveying screw 180. It can be smoothly transferred to the side.
