Manufacturing process of decorative winebottle

Abstract

The invention discloses a manufacturing process of a decorative winebottle, which can decrease the cracking rate and the popping rate of the winebottle. The manufacturing process of the decorative winebottle comprises the following steps of: firstly carrying out applique on the surface of a glass winebottle, and then sending the glass winebottle into a decorating-firing furnace. The manufacturing process is characterized in that the manufacturing process of the glass winebottle in the decorating-firing furnace comprises the following steps of: a) placing the glass winebottle in the decorating-firing furnace for preheating, wherein the preheating time is more than 40 minutes and the glass winebottle is preheated to the temperature of 275 DEG C to 285 DEG C from a room temperature; b) carrying out heating operation after preheating, wherein the heating time is more than 30 minutes and the glass winebottle is heated to the temperature of 580 DEG C to 590 DEG C; c) carrying out heat preservation for 10 to 20 minutes after heating to the temperature of 580 DEG C to 590 DEG C; and d) carrying out cooling processing for the glass winebottle. Through the process, the cracking rate and the popping rate of the winebottle can be decreased, thereby the production qualified rate of the winebottle can be increased, the quality of products is ensured, and the manufacturing process is particularly suitable for being popularized and applied to the production of the glass winebottle.

Description

technical field [0001] The invention relates to a manufacturing process of a decorated wine bottle, which belongs to the field of B65D. Background technique [0002] At present, when producing decorative glass wine bottles, the decal paper is first attached to the outer surface of the glass wine bottle (the pattern that needs to be displayed on the wine bottle is attached to the wine bottle through the decal paper), and then put into the oven. Baking is carried out in the flower furnace, so that the color glaze on the decal paper is firmly fused to the surface of the wine bottle to form a decorative pattern, and then the wine bottle is naturally cooled to room temperature, and the whole flower baking process is completed. [0003] But in the current production process, when the wine bottle is put into the roasting furnace, the temperature in the roasting furnace is generally raised directly from room temperature to about 585°C, and the heating time can be long or short. The ...

AI Technical Summary

Problems solved by technology

[0006] 1. Since the temperature is directly heated to about 585°C during the heating process, if the heating time is fast, the temperature of the wine bottle will rise rapidly, causing the bottle to burst and the pattern to burst; The heating process takes a long time, but if the early heating (before 280°C) is faster, it is easy to cause the bottle to burst and the pattern to burst

[0007] 2. When the color glaze is firmly welded on the surface of the wine bottle, it is easy to cause the glass wine bottle to burst immediately by cooling down to room temperature naturally

Because the natural cooling method makes the bottle body cool down faster in the early stage of cooling, it is easy to generate residual stress in the bottle body, causing the bottle to burst

[0008] 3. The method of putting the glass wine bottle in the baking furnace to heat up will not affect the quality of the wine bottle because of the heating method when the first batch of wine bottles put into the furnace is produced. However, when the production For the second batch of wine bottles, you need to lower the temperature of the heating furnace to room temperature first, and then put the second batch of wine bottles into the baking furnace to heat up. On the one hand, this method wastes a lot of energy, because from 585 The part of the heat that drops to room temperature from around ℃ has not been effectively utilized. In addition, a lot of time is wasted on repeated cooling and heating, thereby reducing production efficiency; If the cooling is not complete, the temperature of the glass wine bottle will rise suddenly after entering the furnace, which will cause the bottle body to burst; in addition, the process of turning to heating after each cooling needs to be strictly controlled, otherwise the heating process will be unreasonable and easy. Causes the bursting of the bottle body, and also increases the operating difficulty of the operator
