Hereinafter, a method of manufacturing a disposable golf ball for outdoor batting practice of the present invention in detail as follows.

1 is a process flow diagram schematically showing a method for manufacturing a disposable golf ball for outdoor batting practice according to the present invention.

1. Raw material grinding process (1st process)

This process is to crush the raw material,

Barley, soybeans, and soybeans dried at a moisture content of 9 to 10% by weight in a 1: 1: 1 weight ratio, or acorns, corn and chestnuts in a 1: 1: 1 weight ratio or leafy soil, rice straw , One of the mixture of rice bran mixed 1: 1: 1 is to grind to 100 ~ 300mesh through a grinder.

In the raw material grinding process, the water content of the raw material is 9 to 10% by weight so that the raw material can be pulverized efficiently. When the water content of the raw material is less than 9% by weight, fine dust may be generated during grinding. , If the moisture content of the raw material exceeds 10% by weight, the operation may be delayed due to entanglement during grinding, and it is preferable to set the moisture content of the raw material to 9 to 10% by weight in the raw material grinding process.

And grinding the raw material to 100 ~ 300mesh in the raw material grinding process so that the core can be easily formed, when the raw material is pulverized less than 100mesh, the binding force between the particles is weakened, the core is easily broken, the raw material is 300mesh If the grinding time exceeds the time required for grinding can be delayed bar, the raw material in the grinding process is preferably the raw material is crushed 100 ~ 300mesh.

At this time, the mixture of barley, soybeans, and soybeans, which is the raw material of 1: 1, by weight, supplies nutrients to sea creatures during natural decomposition, and mixes acorns, corn, and chestnuts by 1: 1: 1 by weight. One mixture provides nutrients to wild animals during their biodegradation. Finally, a mixture of leafy green rice, rice straw, and rice bran in a 1: 1: 1 ratio contains many beneficial natural organisms that eat harmful microorganisms in the soil. As it is, when left outdoors after use, it can continue to serve as soil organic matter, which can provide benefits to soil and plants.

2. Deodorization process (2nd process)

This process is a process to deodorize odors,

The raw material pulverized by the first step is introduced into a biofilter deodorizer to remove odors by 10-20 minutes.

In this deodorization process, the biofilter deodorizer is for effectively removing odor gas of low concentration by using biological method. The microorganisms capable of decomposing odors are attached to and removed, and the odor gas introduced through the suction port is evenly permeated through the front of the filter layer and deodorized, and then discharged as an odorless gas.

At this time, the biofilter deodorizer is to use a conventional one, the detailed description of the structure and principle will be omitted.

On the other hand, in the deodorizing process of the raw material through the deodorizing process, the deodorizing time is preferably 10 to 20 minutes, if the treatment time is less than 10 minutes, the odor removal effect may be insufficient, if the raw material component exceeds 20 minutes It is not preferable because denaturation may occur.

Through the deodorizing process as described above, it is possible to remove the odor peculiar to the raw material, thereby eliminating the discomfort that may occur due to the odor when using the golf ball made of the raw material.

3. Core Forming Process (3rd Process)

This step is to form a core,

The mixture obtained by mixing the raw material, distilled water and starch deodorized by the second process in a ratio of 1: 0.1: 0.4 by weight is introduced into a compression molding machine to form a spherical core having a diameter of 38 to 40 mm.

By forming a spherical core having a diameter of 38 to 40 mm, it can give the same weight as a real golf ball.

Molding the spherical core with the compression molding machine is for molding the core into a hard and nearly round shape.

4. Drying process (4th process)

This process is a drying process,

The core formed by the third step is introduced into a drier and dried for 15 to 30 minutes at 80 to 100 ° C.

In drying the core, it is preferable that the temperature used is 80 to 100 ° C. If the temperature is less than 80 ° C, the drying effect is insufficient to maintain the core shape. Cracking may occur, which is undesirable.

The drying time is preferably 30 minutes or less, preferably 15 to 30 minutes, in consideration of the efficiency in the process period while achieving the core shape and strength retention.

5. Coating layer formation process (5th process)

This step is to form a coating layer,

Forming a coating layer of 3 ~ 5mm made of biodegradable plastic and natural dye on the outer surface of the core dried by the fourth process.

In order to form a coating layer, liquid biodegradable plastics and natural dyes are first poured into a casting mold, and the core is put into the mold. At this time, the thickness of the coating layer is preferably 3 ~ 5mm, if the thickness is less than 3mm, there is a risk that the golf ball is broken when hitting, and if the thickness exceeds 5mm difficult to practice accurate hitting due to the heavy weight This is undesirable.

The raw materials of the natural dyes include onion skin and alum mixture, white rice flour, blue green grass, iris, green maple, sesame, red safflower, ginger, yellow gardenia, turmeric It may be mentioned, it is characterized by using any one of the selected.

By using a variety of natural dyes as described above can not only obtain a golf ball with a variety of colors, it is possible to identify the ball when batting practice outdoors.

In addition, by forming a coating layer, it is possible to protect the core to prevent the breaking of the golf ball during the golf swing.

What put the said core and formed the coating layer is called molding.

6. Semi-drying process (6th process)

This process is a process of semi-drying the moldings,

The molded article having the coating layer formed by the fifth step is introduced into a drier and semi-dried at 30 to 50 ° C. for 5 to 10 minutes.

Semi-drying the molded article on which the coating layer is formed is intended to facilitate the dimple forming process while clearly displaying the dimple shape during the dimple forming.

7. Dimple forming process (7th process)

This process is the process of molding dimples,

The semi-dried molding of the sixth process is introduced into a dimple molding machine to form dimples on the outer surface of the molding.

There is no particular limitation on the molding method in the dimple molding step of the present step, and can be performed by a conventional method using a conventional dimple molding machine.

According to the method of manufacturing disposable golf balls for outdoor batting practice according to the present invention, by allowing the golf practice in the conventional golf practice field in the open air, such as rivers, fields, mountains, reducing the cost of the construction of the golf practice, with a high iron and net Due to this, it does not harm the aesthetics and scenery of the surrounding area and city parks, and it is possible to relieve stress and frustration by practicing golf in a space with a clear view rather than a fixed space. Not only does it allow you to practice batting, but it can also be manufactured at low cost, so that you can reduce the cost burden of golf balls, and it can be beneficial to sea creatures, mountain beasts, and soil by being made of naturally degradable materials.
