Annealing method of injection bottles made from glass tubes

Abstract

The invention discloses an annealing method of injection bottles made from glass tubes. The method includes the following steps: glass bottles are tumbled to a meshy conveyor belt through a dropping groove from the interior of a bottle preparation machine; the glass bottles are conveyed into an annealing furnace through the meshy conveyor belt, then successively pass through a temperature control room for heating, and pass through a heat preservation room for heat preservation annealing; and the glass bottles after heat preservation annealing pass through the underneath of a cooling fan for cooling the glass bottles, and thus the whole annealing process is completed. The annealing process and the production process of the medicinal glass bottles are combined, after the products are molded, the waste heat of the bottle bodies is fully utilized, and automatic and continuous annealing is directly carried out; the energy conversation effect is obvious, the heat preservation performance of the annealing furnace is good and the thermal efficiency is high; the manpower resource for manually carrying glass is saved, the error of manual operation is reduced and the consistency of the quality of the medical glass bottles is improved greatly.

Description

technical field [0001] The invention relates to a glass bottle annealing method, in particular to an annealing method for glass-tube injection bottles. Background technique [0002] In the production process of glass tube injection bottles, in order to eliminate the permanent stress in the formed glass injection bottles, the glass bottles must be heated to a certain temperature for heat preservation and soaking, so as to relax the stress and eliminate the various parts caused by different temperatures. The structural gradient reduces the fragility of glass bottles under different temperature environments. The traditional annealing method is to use a high-power electric furnace to conduct electric heating and annealing on the medicinal glass bottles. The medicinal glass bottles produced by the bottle making machine are packed in iron boxes, and are manually transported to the electric furnace for high-temperature annealing and then manually sent for inspection.

Problems solved by technology

[0003] The above annealing method needs to wait for the bottle body to cool down before manual transfer. After entering the electric furnace, the glass bottle needs to be reheated to an annealing temperature of about 550 degrees Celsius, and after the annealing is completed, the electric furnace needs to be cooled before the next batch of annealing can be carried out. This method consumes a lot of energy, takes a long time, and has low work efficiency. The annealing work is also affected by the proficiency of the staff, and the product quality control is unstable.
