Secondary recycling method of polyethylene plastic products

Abstract

The invention relates to a secondary recycling method of polyethylene plastic products and relates to the technical field of garbage recycling methods. Plastic product recycling equipment is used. The equipment comprises a bottom plate, a fixed frame, a clamping device and a cap removing device and is used for separating a plastic bottle body, a bottle cap and a film outside the bottle body. According to the secondary recycling method of the polyethylene plastic products, the clamping device and the cap removing device are used for clamping, rotating and cap removing at a high automation degree when a plastic bottle is manually pressed, and a clamping plate and a scraping hook are used for assisting in removing the plastic film outside the bottle body, so that the manual intervention degree is reduced, the working content is simplified, and the effect of reducing the labor intensity and the working difficulty of operators is achieved. By means of the clamping device and the cap removing device, the efficiency of separating the bottle body from the bottle cap of the plastic bottle is improved, the cap removing process and the plastic film removing process are better joined, and then the effect of improving the working efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of garbage recycling methods, in particular to a secondary recycling method for polyethylene plastic products. Background technique [0002] The main component of polyethylene plastic is polyethylene. Its raw material ethylene mainly comes from petroleum cracking and cracking, which belongs to petrochemical products. Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of a variety of organic solvents. After adding the corresponding organic solvents, after high temperature heating, they are blown, extruded, or injection molded through plastic molds. plastic container. [0003] Since the film of the plastic bottle body, the plastic used to make the plastic beverage bottle cap and the plastic used to make the bottle body are usually not the same type, and if multiple types of plastics are mixed together for recycling, it is equivalent to allowing one type of pl...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: in the process of separation, they completely rely on manual operation, which makes the degree of manual intervention high, resulting in high labor intensity for operators, and cumbersome operation is difficult; manually unscrew the bottle cap, The process of tearing off the film is carried out separately, and it takes a lot of time in the process of manual operation, resulting in low work efficiency
