Description

Technical Field

[0001] The utility model relates to the technical field of plastic pellet production, in particular to a raw material crusher for plastic pellet production. Background Art

[0002] Plastic pellets, also known as plastic granules or particles, are the basic raw materials in the plastics industry. They are usually in the form of semi-finished products and are used in injection molding, extrusion, blow molding and other processing processes to manufacture various plastic products.

[0003] Plastic pellets are usually in the form of small balls or cakes, and their colors can be adjusted by adding color powder or masterbatch as needed. They have strict standards for size and shape tolerance to ensure uniform heating, flow and molding during processing.

[0004] In the plastic processing industry, choosing the right plastic pellets is one of the keys to manufacturing high-quality plastic products. Different plastic varieties and grades have different performance characteristics, and therefore their scope of application varies greatly.

[0005] In addition to new raw materials, plastic pellets also include:

[0006] Recycled materials: Plastics from post-consumer or post-industrial recycling that can be used to produce plastic pellets after sorting and processing;

[0007] Additives: such as plasticizers, stabilizers, antioxidants, UV absorbers, flame retardants, etc., used to improve the performance of plastics or extend their service life;

[0008] Compound: A mixture of different types of plastics to obtain plastic pellets with specific properties;

[0009] Modified material: A raw material that modifies the base resin by physical or chemical methods to meet specific processing and application requirements.

[0010] The plastic pellet production raw material crusher is a mechanical equipment used to crush large pieces of plastic raw materials or waste plastic products into smaller particles. These crushed plastic particles can be conveniently used for subsequent processing, such as injection molding, extrusion, etc.

[0011] At present, most of the production of plastic pellet raw materials is to recycle waste finished products, which are broken into plastic blocks or plastic pellet structures of different sizes, and then subjected to secondary melting processing. However, since most waste plastic objects have irregular shapes, it is difficult to quickly break them if traditional shearing crushers are used. Repeated shearing is required to achieve overall crushing. Therefore, it is necessary to design a device that can meet the crushing needs of irregular waste plastic objects. Utility Model Content
