Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretching apparatus for forming a synthetic resin coating and buoy,

More particularly, the present invention relates to a stretching apparatus for forming a synthetic resin covered with synthetic resin and a stretching apparatus for forming the same, and more particularly, to an apparatus for stretching an inner diameter of a cover member formed by molding a polypropylene (PP) A hot melt, an inner diameter stiffener, and a cover member are integrally fixed to the outer diameter of the styrofoam buoy by heating while wrapping the styrofoam buoy, and a stretching device for molding.

Generally, buoys used for aquaculture are buoys formed by using styrofoam and buoys formed by blow molding with synthetic resin. Among them, styrofoam buoys are widely used.

Conventional Styrofoam buoys are used by winding a binding wire on both sides of a cylindrical shape. Since a lot of force is applied to the bending groove, if the buoy is used for a long time, it is likely to be broken or deformed by waves, tides and tsunamis.

Also, the styrofoam has a disadvantage in that the surface is not smooth and the shock to the seawater such as waves is transmitted as it is easily broken or deformed.

In addition, if the buoy is damaged, it will cause pollution of the sea by broken fragments, and it is difficult to use even if the bending grooves are slightly damaged.

In order to overcome such drawbacks, a buoy plate is formed by molding a body having a space in an inner diameter thereof with synthetic resin by blow molding. This synthetic buoy plate has weak durability which is a disadvantage of a stick foam buoy, Although the problem has been solved, it is disadvantageous in that it is expensive to manufacture, and there is a disadvantage that the buoy is broken and broken when the buoy is installed in the farm or when the tool is used with the hook, And the efficiency of the work is low.

Examples of such conventional techniques include those disclosed in Utility Model Registration No. 0309039 (registered on Mar. 17, 2003), Utility Model No. 2000-0020942 (published on December 15, 2000), Patent Registration No. 0857470 (Registered trademark) No. 09-22, 2008, and Utility Model Registration No. 227202 (Registered on Apr. 02, 2001). In addition to the disadvantages mentioned above, this prior art has been developed to cover the outer surface of the buoy with a cover to protect the buoy However, there is a disadvantage that it is necessary to fix the buoy by using a string in a part where the buoy can not be put, and there is a disadvantage that it is difficult to adjust the buoyancy when the buoy is not recognized at night, It has to be cleaned periodically because foreign materials such as shells are adhered to the buoyancy. In this case, part of the styrofoam falls together and defects are generated, which causes the buoyancy to be lost.

In order to prevent such drawbacks, the applicant's invention Patent No. 1200020 (registered on Nov. 05, 2002) of the present applicant is more specifically made up of a styrofoam or a synthetic resin

The present invention relates to a buoy for aquaculture that is formed integrally by heating after cross-linking an extruded bag along an outer diameter thereof, and a method for producing the buoy. The method includes forming a bending groove on both sides of a body having a styrofoam and a space, In a buoy for aquaculture used in combination,

The bag is extruded into two layers, molded, irradiated, crosslinked, and then stretched by 20 to 30% to form a bag. The envelope is covered with the styrofoam and the space having a space.

However, in such a conventional technique, it is easy to fix the bag to the body in the course of covering the outer diameter of the body with the outer body of the body so as to be integrated by heating. However, since both sides of the body are rounded, It could not be wrapped and fixed and could not be completed.

In addition, if a hole is formed in one portion when the bag is wrapped, seawater penetrates into the hole, thereby providing a space for microorganisms to live in, or inflating and eventually bursting, So that the function of the buoy is lost.
