Description

Glass bottle manufacturing method {PROCESS FOR GLASS BOTTLE}

The present invention relates to a glass bottle manufacturing method, and more particularly, to a glass bottle manufacturing method for improving the quality of the product, mass production, reducing the manpower by using compression and gas heat.

In general, the glass bottle manufacturing process is as follows.

(1) Mixing process: When the raw material combination ratio is determined to suit the required glass composition, the raw materials are mixed in powder or granular form, and an appropriate amount of cullet is blended therein.

(2) Melting process: Moisture attached to the raw material evaporates, and gases such as carbon dioxide and sulfur dioxide, which are contained in the combustion gas or generated by the decomposition of the raw material, dissolve into the glass. Make a small bubble.

(3) Molding process: The molding of glass products is made by artificial or mechanical method and uses plasticity of glass in viscosity range suitable for molding method.

(4) Slow cooling process: If the glass product is immediately cooled to room temperature after the molding process, there is a risk of uneven residual stress, which can be broken even with a small impact. Therefore, after molding the glass product, it should be heated again to the Annealing Point and then cooled slowly to remove the uneven residual stress.

Ginseng bottles, jars, or immersion bottles vary widely in length, width, weight, and volume, and vary in shape, which affects the production and quality of products according to the skill and fatigue of the technician. As a method of manufacturing a glass bottle, a glass material dissolved in an electric furnace (a kiln) is rolled up with a stainless steel rod according to the type (weight) of the product, and a certain amount is injected into a fixed mold, cut, and then fixedly attached to a movable mold. And take out the glass raw material and use the pneumatic device (AIR) until it is similar to the size of the product to be finished (air balloon principle). Into a mold using air compression. Then open the mold and take out the product to complete. However, the conventional glass bottle manufacturing method has the following problems.

(1) Continuous repetitive up, down, left and right work using human wrist force and the weight of movable mold and glass material that change according to the type of product require skill.

      (2) Depending on the type of product, the fluctuations in length, width, weight, and volume are so severe that the output is not constant.

(3) In the case of a large glass product, problems of thickness imbalance often occur and the product is broken (the thickness of the product is not constant and is broken).

(4) The product's identity and consistency cannot be maintained, and the product value of the product is lowered due to insufficient surface treatment (there is no gloss effect on the product).

(5) The worker is exposed to high temperature for a long time, and the productivity is lowered (summer weather).

(6) Aging of skilled technicians leads to an imbalance in the supply and demand of substitute workers (mainly for beginners with at least 10 years of experience, inability to produce beginners).

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to provide a glass bottle manufacturing method for increasing the efficiency of the production process using compression and gas heat without having a professional manpower.

As an example of a glass bottle manufacturing method according to the present invention,

Winding the molten glass raw material in the furnace with a stainless rod and cutting it to a certain size;

Putting the glass raw material into a compression molding machine and compressing the glass material to be attached to the mobile mold;

Performing gas thermoforming and surface treatment on the glass molded product drawn out from the compression molding machine using a gas heater and an air injector;

Shaping and shaping the glass molded parts,

For the final molding, it is put into a mold for each product and air compression molding while gas heating on the surface is composed of the step of producing the final glass molded product.

Glass bottle manufacturing method according to the present invention has the following differences from the existing manufacturing process.

(1) The present invention does not require skilled technicians compared to the existing manufacturing process, resulting in a reduction in labor shortages and labor costs.

(2) The present invention reduces the production time and the fatigue of workers compared to the conventional manufacturing process through the mechanical principle of compression and gas heat.

(3) The present invention can be applied to mass production of hundreds of kinds of products (ginseng wine bottle, pit bottle, jar jar).

(4) The existing manufacturing process has been affected by the production and quality of the product according to the high temperature working environment and the skill of the worker, but the present invention is not affected by the work environment and the skill of the worker by the mechanical principle of compression and gas heat. .

(5) Existing manufacturing process was limited to the product that can be produced according to the weight, form, type of goods, the present invention can produce all products comprehensively.

(6) In the existing manufacturing process, the quality of the product changes according to the skill of the workers, but the completeness of the product is reduced. However, the present invention can maintain the completeness of the product and bring a drastic improvement in quality.
