Description

Agitation and molding apparatus for eco-friendly synthetic resin composition}

The present invention relates to a device for stirring and molding an eco-friendly synthetic resin composition, which is a material for a support (or support) for supporting crop stems, and more particularly, a synthetic resin, a mineral material, a vegetable material, which is a raw material of the eco-friendly synthetic resin composition. The present invention relates to an apparatus for stirring and molding an eco-friendly synthetic resin composition capable of performing a series of operations in which the bristles extracted from the coconut shell are firmly attached to the paste by stirring so as to be evenly mixed.

Various items are used in everyday life, architecture, civil engineering, and various industrial sites, and the materials that make up the products can be broadly classified into various natural materials, synthetic resins, and metals.

In general, natural materials include wood and stone, and the quantity is limited, and vegetable materials including wood are light and eco-friendly, but have the disadvantage of significantly inferior in durability, and stone materials are usually difficult to process and have the disadvantage of expensive. .

On the other hand, synthetic resins are light and relatively inexpensive, but they are difficult to recycle and have problems of environmental pollution. In the case of metal materials, they have good durability but are heavy and expensive.

In particular, in the case of synthetic resin, since it has excellent moldability and can be formed by mixing various materials, it is used, for example, as a material for a support tree (support) to prevent fall of crops.

However, as mentioned above, in the case of synthetic resins, since regulations are gradually strengthened due to environmental pollution problems, the amount of mixing of synthetic resins is remarkably reduced, and product development of composite materials mixed with eco-friendly materials is being activated.

In addition, since synthetic resins are generally brittle and fragile, various materials are added to improve their physical properties to increase toughness.

In relation to this, if bristles such as coconut shells are cut and mixed with polyethylene, tensile strength and elasticity can be obtained, and the weight to volume can be significantly reduced. However, polyethylene and bristles are not uniformly mixed with a conventional stirrer. In the case of the existing propeller-type stirrer, the bristles get caught in the stirring blades or shaft, causing mechanical failure.
