Description

TECHNICAL FIELD

[0001] The utility model relates to plastic steel strip production technical field more specifically, the utility model relates to a kind of automatic feeding device for plastic steel strip production. BACKGROUND

[0002] Plastic steel strip, also known as plastic packing belt or plastic woven belt, is a material widely used in the packaging industry. It combines the lightness of plastic and the strength of steel, with good corrosion resistance, wear resistance and cost effectiveness. Plastic steel strip is mainly used for bundling and fixing goods to ensure the safety of goods during transportation and storage.

[0003] Plastic steel strip is a strip-shaped material made of plastic materials such as polypropylene, polyethylene and polyester. The plastic raw materials used in processing can be new or recycled. If a mixture of new and recycled materials is used, the two raw materials need to be mixed evenly. In actual production, to balance cost and quality, new and recycled materials are usually mixed for processing. New materials are usually polypropylene particles, polyethylene particles and polyester particles. The most common recycled material is plastic bottle fragments, also known as bottle pieces. After crushing and cleaning, the bottle pieces are mixed with new materials in a certain proportion and transported from the feeding device to the extrusion device for subsequent processing.
