Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a high-borosilicate glass vessel with a suspended bubble effect and a processing technology thereof. Background Art

[0002] Due to its transparent characteristics, glassware can present luster under the illumination of light sources, and can form beautiful light and shadow effects under the refraction of the contents. In the manufacture of glassware, in order to ensure that the glassware is pure, luster is smooth, and quality is controllable, measures are usually taken to eliminate bubbles generated in the glassware processing project. For example, the Chinese patent with the authorization announcement number CN11326999B discloses a method for controlling bubbles in the glassmaking process. The above patent discloses a method for shrinking bubbles on the free surface of a certain amount of molten glass contained in a container or flowing through a container, thereby minimizing the re-entrainment of bubbles into the volume of the molten glass and reducing the occurrence of bubbles in the finished glass product produced by the molten glass. A method for identifying the source position of the bubble is also described.

[0003] It can be seen that in the prior art, bubbles formed on glass are usually caused by product quality defects, and the position and size of the bubbles are difficult to control. Therefore, products with bubbles are generally treated as defective products during the glassware production process, or these bubbles are eliminated through some means.

[0004] However, the inventors have discovered that if bubbles of a specific size and a specific position can be suspended inside a glass container so that they are illuminated by a light source and combined with the refraction of the contents, a unique light and shadow effect can be presented. However, the prior art has not reported any process that can achieve a stable presentation of bubbles of a specific size and shape inside a glass container, thereby achieving a unique light and shadow effect. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a high borosilicate glassware with a suspended bubble effect and a processing technology thereof, so that bubbles of a specific size and shape can be accurately presented at specific positions in the inner layer of the glassware, so that the prepared glassware presents a unique light and shadow effect.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] S2: roasting the outer surface of the cylinder of the inner glass layer over a flame to soften the outer surface of the cylinder;

[0010] S3: inserting and pulling out a mold rod of a specific shape at a specific position on the outer surface of the cylindrical body, so that a blind hole of a specific shape is formed on the outer surface of the cylindrical body;

[0011] S4: an outer layer of glass in the shape of a circular cylinder is sleeved on the outer surface of the cylindrical body, the outer layer of glass is melted by heating, and attached to the surface of the inner layer of glass, so that the inner layer of glass and the outer layer of glass are melted into one, and the ventilation pipe at one end of the inner layer of glass is melted to be sealed to form the bottom of the container;

[0012] S5: shaping the inner glass and the outer glass to produce a glass vessel with a suspended bubble effect.

[0013] Furthermore, in the processing technology of the above-mentioned high borosilicate glassware with suspended bubble effect, in S2, the outer surface of the cylindrical body of the inner layer of glass is roasted on the flame sprayed by the first flame sprayer, the spray diameter of the flame of the first flame sprayer is 1-1.2 cm, the flame length is 8-12 cm, the roasting time of the cylindrical body is 5-7 seconds, and during the roasting process, the ventilation tube continues to rotate around its axis.

[0014] Furthermore, in the processing technology of the high borosilicate glassware with suspended bubble effect, in S3, the head of the mold rod is made of metal, and the head of the mold rod has the shape required for the bubble. During S3, the outer surface of the cylindrical body needs to be drilled with a blind hole at a distance of 0.1-0.5 cm. After the head of the mold rod is burned red in the flame, it is quickly inserted and pulled out at the position on the outer surface of the cylindrical body where the blind hole needs to be drilled.

[0015] Furthermore, in the processing technology of the high borosilicate glassware with the suspended bubble effect, the S5 is specifically: continuously blowing air into the inner layer of glass through the vent pipe, and uniformly heating the surface of the outer layer of glass through the flamethrower for 5-20 seconds;

[0016] The ventilation tube is held and the outer layer of glass is placed on a shaping mold for rolling shaping. The rolling shaping mold is provided with an arc-shaped groove adapted to the outer surface of the glassware. The ventilation tube is rotated to shape the outer surface of the outer layer of glass through the arc-shaped groove. During the shaping process, air is blown into the ventilation tube. After repeating the above heating and rolling shaping steps for multiple times, the ventilation tube and the redundant parts connected thereto are removed to obtain a glassware with a suspended bubble effect.

[0017] Furthermore, in the processing technology of the high borosilicate glassware with suspended bubble effect, the head of the mold rod is in the shape of a sphere, an ellipsoid, a teardrop, a cylinder, a polygonal prism or an elliptical body.

[0019] Furthermore, in the processing technology of the high borosilicate glassware with the suspended bubble effect, in S4, the outer layer of glass is rolled and shaped on a cooling plate every 6-9 seconds of baking.

[0020] The present invention also protects the high-borosilicate glassware with suspended bubble effect obtained by the processing technology of the high-borosilicate glassware with suspended bubble effect.

[0021] The beneficial effects of the present invention are as follows: blind holes are formed by inserting and pulling out a mold rod on the softened surface of the inner glass when the surface is softened, and then the outer glass in the shape of a ring cylinder is placed outside the cylindrical body of the inner glass, and flame roasted to melt the inner glass and the outer glass into one, so that the blind hole formed by the inner glass is sandwiched between the inner glass and the outer glass to form a suspended bubble shape. In this process, the position, number and size of the bubbles can be accurately set according to needs, so that the prepared glassware presents a unique light and shadow effect.

[0031] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0032] Please refer to Figures 1 to 5 The specific embodiment of the present invention relates to a processing technology of a high borosilicate glassware with a suspended bubble effect, comprising the following steps:

[0033] S1: manufacturing an inner glass 1, wherein the inner glass 1 is a rotating tube, and the inner glass 1 comprises a cylindrical body 11 in the middle and a vent pipe 12 coaxially connected to both ends of the cylindrical body 11;

[0034] S2: roasting the outer surface of the cylindrical body 11 of the inner glass 1 over a flame to soften the outer surface of the cylindrical body 11;

[0035] S3: inserting and pulling out a mold rod 3 of a specific shape at a specific position on the outer surface of the cylindrical body 11, so that a blind hole 13 of a specific shape is formed on the outer surface of the cylindrical body 11;

[0036] S4: an outer glass layer 2 in the shape of a circular cylinder is sleeved on the outer surface of the cylindrical body 11, the outer glass layer 2 is melted by heating, and attached to the surface of the inner glass layer 1, so that the inner glass layer 1 and the outer glass layer 2 are melted into one, and the ventilation pipe 12 at one end of the inner glass layer 1 is melted to be sealed, so as to form the bottom of the container;

[0037] S5: shaping the inner glass 1 and the outer glass 2 to obtain a glass vessel with a suspended bubble effect.

[0038] In the above embodiment, the blind hole 13 is formed by inserting and pulling out the mold rod 3 on the softened surface of the inner glass 1 when the surface is softened, and then the outer glass 2 in the shape of a ring cylinder is put on the outside of the cylindrical body 11 of the inner glass 1, and the inner glass 1 and the outer glass 2 are fused into one by flame roasting, so that the blind hole 13 formed by the inner glass 1 is sandwiched between the inner glass 1 and the outer glass 2 to form a suspended bubble shape. In this process, the position, number and size of the bubbles can be accurately set according to needs, so that the prepared glassware presents a unique light and shadow effect.

[0039] As a preferred embodiment, in S2, the outer surface of the cylindrical body 11 of the inner glass 1 is roasted on the flame sprayed by the first flame sprayer, the spray diameter of the flame of the first flame sprayer is 1-1.2 cm, preferably 1.1 cm, the flame length is 8-12 cm, preferably 10 cm, the roasting time of the cylindrical body 11 is 5-7 seconds, and during the roasting process, the ventilation pipe 12 continues to rotate around its axis.

[0040] In the above implementation mode, in S2, the flame size of the flamethrower is the key to the process. If the flame is too small, it is difficult to fully soften the outer layer of the inner glass 1, resulting in difficulty for the mold rod 3 to form a blind hole 13 on the surface of the inner glass 1. If the flame roasting time is not too long, otherwise it is easy to cause wire drawing when the mold rod 3 is pulled out, affecting the quality of the blind hole 13 forming. If the flame is too large, it is easy to make the inner layer of the inner glass 1 too soft, causing the inner wall of the inner glass 1 to sag during the insertion and extraction of the mold rod 3, affecting the flatness of the inner wall of the inner glass 1.

[0041] As a preferred embodiment, in S3, the head of the mold rod 3 is metal, and the head of the mold rod 3 has the shape required by the bubble. During S3, the outer surface of the cylindrical body 11 needs to be drilled with a blind hole 13 at a distance of 0.1-0.5 cm, preferably 0.2 cm. After the head of the mold rod 3 is burned red in the flame, it is quickly inserted and pulled out at the position on the outer surface of the cylindrical body 11 where the blind hole 13 needs to be drilled.

[0042] In the above embodiments, during the insertion and extraction of the mold rod 3 , the outer surface of the cylindrical body 11 needs to always be close to the edge of the flame to maintain the softening degree of the outer surface of the inner glass 1 , thereby ensuring the quality of the blind hole 13 .

[0043] As a preferred embodiment, S5 specifically comprises: continuously blowing air into the inner glass 1 through the vent pipe 12, and uniformly heating the surface of the outer glass 2 through the flame sprayer for 5-20 seconds, preferably 13 seconds;

[0044] Hold the vent tube 12, place the outer layer of glass 2 on a shaping mold for rolling shaping, the rolling shaping mold is provided with an arc groove adapted to the outer surface of the glassware, rotate the vent tube 12, so that the outer surface of the outer layer of glass 2 is shaped through the arc groove, and during the shaping process, blow air into the vent tube 12, and after repeating the above heating and rolling shaping steps for multiple times, remove the vent tube 12 and the redundant parts connected thereto, and obtain a glassware with a suspended bubble effect.

[0045] In the above embodiment, since the ventilation tube 12 at one end of the inner glass 1 is blocked, when air is blown from the ventilation tube 12 at the other end, the inner glass 1 can expand outward under the action of air pressure and cooperate with the external mold to achieve the shaping operation of the glassware.

[0046] As a preferred embodiment, the head of the mold rod 3 is in the shape of a sphere, an ellipsoid, a teardrop, a cylinder, a polygonal column or an elliptical body.

[0047] In the above embodiments, the shapes of the suspended bubbles are various and can be flexibly selected according to the changes in the shape of the head of the mold rod 3 .

[0048] As a preferred embodiment, S4 specifically comprises: sleeve an outer glass layer 2 in the shape of a ring cylinder on the outer surface of the inner glass layer 1, roast the outer glass layer 2 with the flame sprayed by the second flame sprayer to melt the outer glass layer 2 and adhere it to the surface of the inner glass layer 1, so that the inner glass layer 1 and the outer glass layer 2 are melted into one, and the ventilation pipe 12 at one end of the inner glass layer 1 is melted to be sealed to form the bottom of the container; the diameter of the flame sprayed by the second flame sprayer is 1.7-2.0 cm, preferably 1.8 cm, and the length of the flame is 20-25 cm, preferably 22 cm.

[0049] In the above implementation mode, in S4, a larger flame is required to fuse the inner glass 1 and the outer glass 2 compared to S2, and a larger flame is not suitable for this process. The flame size of the above specifications can ensure rapid fusion between the inner glass 1 and the outer glass 2, and can ensure that the blind hole 13 of the inner glass 1 forms a complete and controllable suspended bubble shape.

[0050] As a preferred embodiment, in S4, the outer layer of glass 2 is rolled and shaped on a cooling plate every 6-9 seconds of baking. Since different types of glassware have different shapes, in this step, the outer layer of glass 2 can be rolled and shaped at intervals during the melting process, so that the outer layer of glass 2 gradually forms the shape corresponding to the desired glassware.

[0051] The present invention also protects the high-borosilicate glassware with suspended bubble effect obtained by the processing technology of the high-borosilicate glassware with suspended bubble effect.

[0052] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
