Production process of winebottles with decorations

Abstract

The invention discloses a production process of winebottles with decorations and can effectively reduce the occurrence probability of black spots on the surfaces of glass winebottles. The production process of winebottles with decorations comprises: a. applying appliques on the external surfaces of the glass winebottles; b. placing the multiple glass winebottles with appliques into the inner cavity of a decoration firing furnace for baking, so that a coloured glaze can be welded on the external surfaces of the glass winebottles. Specifically, step b consists of the steps of: while putting themultiple glass winebottles in the decoration firing furnace, keeping the volume sum of coloured glazes of appliques on the multiple glass winebottles at an amount of V1 and the inner cavity volume ofthe decoration firing furnace at an amount of V2, with the ratio of V1 to V2 less than or equal to 0.01 per thousand, and controlling an equal space between any two glass winebottles; heating the glass winebottles to a temperature of 580DEG C-590DEG C in the decoration firing furnace by means of preheating and temperature raising, and making the coloured glazes firmly welded on the external surfaces of the glass winebottles through an insulation process; cooling the glass winebottles. The process provided in the invention can effectively prevent formation of black spots on the surfaces of glass winebottles.

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 glass wine bottles with decorations, the decal operation is first performed on the surface of the glass wine bottle (that is, 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 decal furnace for decal Baking, 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 bottle is naturally cooled down to room temperature, that is, the entire decal process is completed; In addition to forming decorative patterns on the surface of the wine bottle, in order to make the wine bottle have a hazy aesthetic effect, the existing process also forms a decorative effect on the surface of the wine bottle by sandblasting. [0003] However, i...

AI Technical Summary

Problems solved by technology

[0006] 1. Since the wine bottle is placed arbitrarily in the baking furnace, during the baking process, the colored glaze on the decal on the surface of the wine bottle volatilizes to form carbon black. In this way, when the wine bottle is placed in the baking furnace When there are many wine bottles, the atmosphere in the furnace is poor, and it is easy to form black spots on the wine bottles during the baking process, thus forming product defects

[0007] 2. 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

[0008] 3. After 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

[0009] 4. The method of heating the glass wine bottles in the baking furnace will not affect the quality of the wine bottles because of the heating method when the first batch of wine bottles are 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
