Efficient environment-friendly glass bottle blowing process

Abstract

The invention belongs to the technical field of glass bottles, and specifically relates to an efficient environment-friendly glass bottle blowing process. A bottle blowing mold used in the process comprises a body, the body is composed of two split bodies, which are arranged in a bilateral symmetry mode, cavities used for controlling the forming of a glass bottle are formed in the adjacent sides of the split bodies, annular grooves used for fixing a bottle blank are formed in the tops of the cavities, bottle opening holes are formed in the upper portions of the annular grooves, and spiral bottle opening threaded grooves are formed in the bottle opening holes. A thin-wall heating ring is arranged at each bottle opening hole, an circular ring is arranged in the bottle opening hole and corresponds to a heating ring; the inner diameter of the circular ring is slightly greater than the outer diameter of the bottle blank, the circular ring is made of iron; the heating ring is connected witha power source through a controller, the heating ring heats the circular ring through high frequency, the fusion efficiency of the circular ring, reinforcing wires and a bottle blank is improved, andthe glass bottle strength is improved.

Description

technical field [0001] The invention belongs to the technical field of glass bottles, in particular to a high-efficiency and environment-friendly glass bottle blowing process. Background technique [0002] Glass bottles are packaging containers for food, beverages and many products. They are widely used. Glass is also a kind of packaging material with a long history. With many kinds of packaging materials pouring into the market, glass containers still occupy an important position in beverage packaging. The manufacture of glass bottles usually goes through four processes of batching, melting, forming and annealing. During the molding process, it is necessary to inject the molten glass stock solution into the molding mold with a water cooling system, and rapidly cool the molding, so that most of the energy is stored in the glass bottle body, forming internal stress. If the internal stress is too large, it is easy to cause the bottle to crack. In order to eliminate the inte...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of blowing the glass bottle through the mold in the prior art, it is necessary to quickly cool down the mold so that the preform can be rapidly solidified after expansion, but due to the uneven distribution of the cooling channels, The cooling speed of the bottle body is not uniform, and it takes a long time to lower the bottle body to cool all parts of the bottle body to the predetermined temperature, which affects the production efficiency of the glass bottle. The problem of sudden cold and sudden heat is easy to burst and hurt people. This invention proposes a high-efficiency and environmentally friendly glass bottle blowing process.
