More particularly, the present invention relates to an apparatus for removing foreign substances from a resin material, and more particularly, to an apparatus for removing foreign matters from a resin material by interposing between an injection apparatus for producing a plastic product or an optical product by melting and molding a resin material The injection device effectively removes foreign matter such as dust or water attached to the resin raw material before the resin raw material is introduced and enables the resin raw material to maintain the temperature condition optimized to the specification of the product so that the quality and yield of the finished product And to a device capable of maximizing it.

Generally, plastic injection moldings or extrudates are prepared by melting resin raw materials in the form of pellets. In the production of the plastic molded article, the pelletized resin raw material is heated and melted through the raw material heating section, and then transferred to the molding section to be molded into various products.

The pelletized resin raw material is liable to be mixed in the process of being manufactured in a manufacturing factory and then being put into a hopper for transportation, storage, or use. Particularly, since the resin raw material has a characteristic that static electricity easily occurs during processing or transportation, various foreign substances are likely to adhere to the surface of the resin raw material, and therefore, it is very difficult to maintain the original purity.

Examples of foreign substances that are likely to adhere to the resin raw material during transportation or storage include dust from the outside, fine materials such as dust in packing paper dust and packing bags, resin powder in the form of powder, and broken raw materials in the form of chips. When a plastic product is produced using such a resin material with foreign substances, defective products such as microcracks are generated, and since the raw material pieces having the same composition as the resin material have boiling points and boiling speeds different from those of the finished product It is possible to cause various defects in the finished product.

In addition, the moisture content of the resin material frequently occurs during transportation or storage depending on the surrounding environment. Like the dust or fine particles, the moisture mixed with the resin material greatly degrades the quality of the synthetic resin product.

Particularly, in the case of a plastic product in which transparency and coloring degree are important, such as a lens or an optical product such as a lens, maintaining the purity of the resin raw material greatly affects the quality and performance of the product. Therefore, before melting the resin raw material, , It is necessary to remove foreign matter such as water.

 For this reason, it is a common practice to remove foreign substances by using a foreign material removing device before melting the resin raw materials in the production of plastic products, and then to melt and form them.
