Automatic recycling method for plastic bottles

Abstract

The invention discloses an automatic recycling method for plastic bottles. An automatic cleaning and shredding machine is used in the method; when a plastic bottle body is recycled by the method, a rotating shaft is arranged at one end of an opening of the plastic bottle body; a part, which extends into the plastic bottle body, of the rotating shaft is respectively hinged to a first connecting rod and a second connecting rod; a brush is arranged on the first connecting rod; a blade is arranged on the second connecting rod; an adsorption block is arranged at the other end of the opening of the plastic bottle body; an air channel is formed in the adsorption block and is connected with an air extractor; the automatic cleaning and shredding machine further comprises a connecting rod; a mounting seat is hinged to the middle of the connecting rod and is fixed on an external rack; one end of the connecting rod is hinged to the adsorption block; a slot is formed in the other end of the connecting rod; and a plurality of steel balls which can move along the slot and are discharged out of the slot are arranged in the slot. After being shredded in the scheme, the plastic bottle body can also be cleaned, the step of recycling the plastic bottle body is omitted, and the recycling efficiency of the plastic bottle body is improved effectively.

Description

technical field [0001] The invention relates to a method for recycling plastic bottles. Background technique [0002] The extensive use of plastic products in modern society, especially the continuous and rapid development of the beverage industry has led to the extensive use of plastic containers, and in the recycling process, due to the large space occupied by plastic containers, it has brought great trouble to storage and transportation. It has also brought about the discarding and accumulation of a large number of waste plastic containers and the problems of recycling. At present, the commonly used methods for processing a large number of plastic bottles are as follows: one is to chop waste plastic bottles by the shear force generated between the moving knife with several blades rotating at high speed and the fixed knife, and its knife body and blades will be broken due to It can’t withstand strong impact and is easy to be damaged; the second is to use the knife shafts ...

AI Technical Summary

Problems solved by technology

[0004] But the above-mentioned scheme has the following problems when actually shredding plastic bottles: plastic bottles are generally used for packaging beverages or other substances before recycling, so when plastic bottles are recycled, the inner surface of plastic bottles Residual liquid or dust and other substances are often adhered, so that after the plastic bottle is shredded, an additional cleaning step is required for the plastic bottle, which will increase the recycling process of plastic bottles and the efficiency of recycling
