Description

Technical Field

[0001] The present invention relates to the technical field of high borosilicate glass container production, and in particular to a high borosilicate glass container based on laser cutting patterns and a production process thereof. Background Art

[0002] Laser cutting can achieve very fine cutting, which is suitable for processing complex patterns and high-precision requirements. The laser beam can be focused to a very small size, making the processing accuracy extremely high, which is superior to other traditional processing methods; in the pattern processing technology of glass containers, most of them are through hand-painted patterns or isomorphic screen-printed patterns on the outer surface of the glass, but this pattern structure can only be a plane structure and cannot present a three-dimensional pattern effect. There is no technical solution reported in the prior art to achieve a three-dimensional pattern on the side wall of a glass container by laser cutting. Those skilled in the art may consider that on the one hand, the outline of the pattern can only be formed by hollowing out the side wall of the glass container through laser cutting to form a three-dimensional pattern, and the overall pattern cannot be completely cut off to form a hollow pattern, otherwise it will cause the liquid in the container to flow out from the hollow pattern, and laser cutting can only be performed from the outer surface of the glass container, and the incision of laser cutting is easy to cause users to scratch their fingers when holding it. Summary of the invention

[0003] The technical problem to be solved by the present invention is: a high borosilicate glass container based on a laser cutting pattern and its production process, so that the inner wall of the glass container forms a hollow laser cutting pattern, which on the one hand forms a three-dimensional pattern light and shadow effect, and on the other hand avoids cutting the user's fingers when holding it, and also avoids liquid from flowing out of the laser cutting pattern of the container.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The production process of borosilicate glass containers based on laser cutting patterns includes the following steps:

[0006] S1: making a glass tube, wherein the glass tube is a rotating tube, the glass tube comprises a cylindrical body in the middle and a vent pipe coaxially connected to one end of the cylindrical body, and the other end of the cylindrical body is provided with an opening; making a cylindrical glass tube, the inner diameter of the glass tube is 0.1-1 mm larger than the outer diameter of the cylindrical body, one end of the glass tube is sealed and the other end is open;

[0007] S2: The outer wall of the glass tube is cut by laser to form a hollow cutting pattern, and the outer wall of the glass tube is roasted to soften it appropriately;

[0008] S3: coaxially sleeve the open end of the glass cylinder onto the outer wall of the cylindrical body of the glass tube, so that the inner wall of the glass cylinder and the outer wall of the cylindrical body are gap-matched;

[0009] S4: The glass tube and the cylindrical body are fixedly fused by heating three points distributed in a circumferential array on the edge of the opening end of the glass tube;

[0010] S5: roasting the outer surface of the glass tube to melt the side wall of the glass tube and make it adhere to the inner glass surface, so that the glass tube and the glass tube are melted into one, forming a preliminary container;

[0011] S6: shaping the container embryo to obtain a high borosilicate glass container based on the laser cutting pattern.

[0012] Furthermore, in the production process of the borosilicate glass container based on the laser cutting pattern, the S6 is specifically to continuously blow air into the container embryo through the ventilation pipe, and at the same time, evenly roast the outer surface of the container embryo for 5-20 seconds through the flamethrower;

[0013] The ventilation tube is held and the container embryo 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 glass container. The ventilation tube is rotated to shape the outer surface of the container embryo through the arc-shaped groove. During the shaping process, air is blown into the ventilation tube. After repeating the above-mentioned roasting and rolling shaping steps for multiple times, the ventilation tube and the redundant parts connected thereto are removed to obtain a high borosilicate glass container based on a laser cutting pattern.

[0014] Furthermore, in the above-mentioned production process of high borosilicate glass containers based on laser cutting patterns, in S2, a first flame thrower is used for roasting, the flame diameter sprayed by the first flame thrower is 1.7-2.0 cm, the flame length is 20-25 cm, the roasting time is 45-55 seconds, and the glass tube is continuously rotated during the roasting process, and the flame core and outer flame are switched at intervals for roasting.

[0015] Furthermore, in the above-mentioned production process of borosilicate glass containers based on laser cutting patterns, in S4, a second flamethrower is used for roasting, the flame diameter of the second flamethrower is 1-1.2 cm, the flame length is 8-12 cm, and each welding point is roasted with the external flame for 3-5 seconds.

[0016] Furthermore, in the above-mentioned production process of high borosilicate glass containers based on laser cutting patterns, in S5, a first flame thrower is used for roasting, the flame diameter sprayed by the first flame thrower is 1.7-2.0 cm, the flame length is 20-25 cm, the roasting time is 45-55 seconds, and the glass tube is continuously rotated during the roasting process, and the outer flame is continuously used for roasting, and the roasting time is 200-240 seconds.

[0017] Furthermore, in the above-mentioned production process of borosilicate glass containers based on laser cutting patterns, in S5, the outer layer of glass is rolled and shaped on a cooling plate every 6-9 seconds of baking.

[0018] The present invention also protects the high borosilicate glass container product produced by the above-mentioned production process of high borosilicate glass container based on laser cutting pattern.

[0019] The beneficial effects of the present invention are as follows: by laser cutting the cylindrical outer wall of the glass tube, the cutting part is completely cut off to form a hollow pattern structure; by welding the glass tube and the glass tube, the glass tube forms the outer wall of the container and covers the position of the hollow pattern, so that the hollow pattern is formed in the inner layer of the container, on the one hand, a three-dimensional pattern light and shadow effect is formed; on the other hand, it avoids cutting the fingers of the user when holding the container, and also avoids the liquid from flowing out of the laser cutting pattern of the container. By using the laser cutting process to form the hollow pattern, complex and changeable hollow patterns can be formed on the glass container; when the hollow pattern is laser cut, the cutting is still performed from the outer wall of the glass tube, the operation difficulty is low, and the yield rate is high.

[0027] 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.

[0028] Please refer to Figures 1 to 4 The specific embodiment of the present invention relates to a production process of a high borosilicate glass container based on a laser cutting pattern 13, comprising the following steps:

[0029] S1: manufacturing a glass tube 1, wherein the glass tube 1 is a rotating tube, and the glass tube 1 comprises a cylindrical body 12 in the middle and a vent pipe 11 coaxially connected to one end of the cylindrical body 12, and the other end of the cylindrical body 12 is provided with an opening; manufacturing a cylindrical glass tube 2, wherein the inner diameter of the glass tube 2 is 0.1-1 mm larger than the outer diameter of the cylindrical body 12, and one end of the glass tube 2 is sealed and the other end is open;

[0030] S2: The outer wall of the glass tube 1 is cut by laser to form a hollow cutting pattern 13, and the outer wall of the glass tube 1 is roasted to soften it appropriately;

[0031] S3: The open end of the glass cylinder 2 is coaxially sleeved on the outer wall of the cylindrical body 12 of the glass tube 1, so that the inner wall of the glass cylinder 2 and the outer wall of the cylindrical body 12 are gap-matched;

[0032] S4: The glass tube 1 and the cylindrical body 12 are fixedly welded by heating three points distributed in a circumferential array on the edge of the opening end of the glass tube 2;

[0033] S5: roasting the outer surface of the glass tube 2 to melt the side wall of the glass tube 2 and adhere it to the inner glass surface, so that the glass tube 1 and the glass tube 2 are melted into one, forming a preliminary container;

[0034] S6: shaping the container embryo to obtain a high borosilicate glass container based on the laser cutting pattern 13.

[0035] In the above embodiment, laser cutting is performed on the outer wall of the cylindrical body 12 of the glass tube 1, and the cut portion is completely cut off to form a hollow pattern structure. The glass tube 2 and the glass tube 1 are welded together to form the outer wall of the container, which is covered at the position of the hollow pattern, so that the hollow pattern is formed in the inner layer of the container. On the one hand, a three-dimensional pattern light and shadow effect is formed, and on the other hand, it prevents the user from cutting his fingers when holding the container, and also prevents the liquid from flowing out from the laser cutting pattern 13 of the container. The hollow pattern is formed by the laser cutting process, and complex and changeable hollow patterns can be formed on the glass container. When the hollow pattern is laser cut, the cutting is still performed from the outer wall of the glass tube 1, and the operation difficulty is low and the yield rate is high.

[0036] As a preferred embodiment, the S6 specifically comprises: continuously blowing air into the container embryo through the ventilation pipe 11, and uniformly roasting the outer surface of the container embryo for 5-20 seconds through a flamethrower;

[0037] The ventilation tube 11 is held and the container embryo 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 glass container. The ventilation tube 11 is rotated to shape the outer surface of the container embryo through the arc-shaped groove. During the shaping process, air is blown into the ventilation tube 11. After repeating the above-mentioned roasting and rolling shaping steps for multiple times, the ventilation tube 11 and the redundant parts connected thereto are removed to obtain a high borosilicate glass container based on the laser cutting pattern 13.

[0038] As a preferred embodiment, in S2, the roasting is performed using a first flame injector, the flame diameter of the first flame injector is 1.7-2.0 cm, the flame length is 20-25 cm, the roasting time is 45-55 seconds, and the glass tube 1 is continuously rotated during the roasting process, and the flame core and outer flame are switched at intervals.

[0039] In the above embodiment, when the cylindrical body 12 of the glass tube 1 and the glass tube 2 are sleeved and welded, the cylindrical body 12 of the glass tube 1 needs to be moderately melted and softened. This step is very critical for flame control and is a key point in the process. If the baking time is too long or the flame intensity is too high, the glass tube 1 will easily be over-softened and deformed, making it impossible for the glass tube 2 and the glass tube 1 to be normally sleeved. If the flame intensity is not enough or the baking time is not enough, it will be easy to make it impossible to achieve tight welding of the outer wall of the glass tube 1 and the inner wall of the glass tube 2 in the subsequent steps.

[0040] As a preferred embodiment, in S4, the roasting is performed using a second flame injector, the flame sprayed by the second flame injector has a diameter of 1-1.2 cm, a flame length of 8-12 cm, and each welding point is roasted with the external flame for 3-5 seconds.

[0041] In the above implementation manner, when the glass tube 2 is sleeved on the outside of the glass tube 1, the two need to be pre-fused and fixed first. The three-point positioning welding at a specific position can save welding time and pre-fix the two, so that when the operator holds the ventilation tube 11 and rotates it, the glass tube 2 can be driven to rotate stably and synchronously to avoid falling; the pre-fusion step still requires great attention to the intensity and time of the flame, and the time should not be too long, otherwise the outer wall of the preheated glass tube 1 will cool down and affect the subsequent welding; the flame intensity should not be too large, otherwise it will affect the uniformity of the container surface.

[0042] As a preferred embodiment, in S5, the roasting is performed using a first flame injector, the flame diameter of the first flame injector is 1.7-2.0 cm, the flame length is 20-25 cm, the roasting time is 45-55 seconds, and the glass tube 1 is continuously rotated during the roasting process, and the external flame is continuously used for roasting, and the roasting time is 200-240 seconds.

[0043] In the above embodiment, in S5, the glass tube 1 and the glass cylinder 2 are tightly fused together by a specific flame intensity and roasting time to form an integral glass container. The joint between the glass tube 1 and the glass cylinder 2 cannot be seen from the outside. From the perspective of light and shadow effects, the hollow pattern will be suspended on the side wall of the container. Figure 4 .

[0044] As a preferred embodiment, in S5, the outer layer of glass is rolled and shaped on a cooling plate every 6-9 seconds of baking.

[0045] The present invention also protects the high borosilicate glass container product produced by the production process of the high borosilicate glass container based on the laser cutting pattern 13.

[0046] 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.
