Description

Technical Field

[0001] The invention belongs to the technical field of alkali-free amber glass, in particular to an alkali-free amber glass which is easy to be blown and formed and a forming device. Background Art

[0002] As daily necessities, glass bottles are widely used in beer, beverages, medicines and other fields. Its molding methods are mainly divided into drawing molding and blowing molding. Drawing molding is suitable for small-volume bottles. The softened glass is drawn into a tube by mechanical traction and then cut and sealed. Blowing molding is suitable for large-size bottles. It is formed in the mold by blowing air into the softened glass. The blowing method is divided into blow-blowing method and press-blowing method. The former is used for small-mouth bottles and the latter is used for wide-mouth bottles. The production of glass bottles first requires the batch materials to be heated in a high-temperature pool kiln or pool furnace into a uniform, bubble-free glass liquid. Subsequently, the glass liquid flows into the mold through the feed channel at 1000℃-1200℃ for molding. The composition of the glass and the viscosity changes in the molding temperature range are crucial to the molding quality.

[0003] At present, the commonly used glass bottle materials are soda-lime glass or low-borosilicate glass, which are easy to shape but have poor chemical stability and are not suitable for the storage of high-end drugs and chemical reagents, because alkali metal ions are easy to react with drugs to cause pollution, while medium-borosilicate glass and high-borosilicate glass with high chemical stability are difficult to prepare large-sized glass bottles due to their high molding temperature and high viscosity. In the process of blowing glass bottles, it is also found that the cost of existing blowing devices is relatively expensive. For example, a glass bottle molding processing equipment and method with publication number CN118388115A requires a driver for each mold to drive the opening and closing of the mold, and the operation is relatively cumbersome. Secondly, after the glass is formed, no cooling measures are taken, resulting in very slow solidification of the glass bottle solution. Summary of the invention

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] An alkali-free amber glass that is easy to be blown and a forming device are prepared by the following steps:

[0040] S1. Weigh and mix alkali-free amber glass raw materials in a specific ratio, add a colorant and stir evenly;

[0041] S2. The mixed raw materials are fed into a glass melting furnace and melted at a high temperature exceeding 1400°C. During the melting process, the coloring effect of Fe2O3 and TiO2 is controlled by adjusting the redox atmosphere in the melting furnace and utilizing the reducing property of C to obtain the desired amber color;

[0042] S3, the molten glass flows into the droplet in front of the forming mold through the supply channel, the temperature of the glass liquid should be controlled within a range suitable for blow molding, and the glass liquid is blown into shape by the blow molding equipment to form the desired shape;

[0043] S4. The formed glass needs to be annealed to eliminate internal stress and prevent cracking;

[0044] The alkali-free amber glass raw materials are composed of 55%-60% SiO2, 0.1%-5% Al2O3, 0.1%-5% B2O3, 5%-20% CaO, 5%-20% BaO, 5%-20% ZnO, 0.1%-1.5% Fe2O3, 0.5%-3.5% TiO2, 0.1%-3% C and 0.1%-3% X2O3 according to mass percentage; wherein the total mass percentage of SiO2+Al2O3 is 58%-65%. It should be noted that SiO2 is a glass former and a component constituting the glass skeleton, and Al2O3 is an intermediate oxide that controls SiO2+Al2O3. The total mass percentage of l2O3 is 58-65%, which helps to enhance the density of the glass network structure and improve the chemical stability of the glass. The viscosity will not be too high, which is conducive to blowing molding. B2O3 can reduce the brittleness of the glass and improve the chemical stability of the glass. At the same time, B2O3 is also a good fluxing agent, which can greatly reduce the melting temperature of the glass and is also beneficial to the vitrification process. The total mass percentage of CaO+BaO+ZnO is 26%-32.5%, and (CaO+BaO) / ZnO is 2.5-6. It should be noted that the glass does not contain alkali metal oxides, which creates great difficulties for melt molding. For this reason, the content of alkaline earth metal oxides is increased, including CaO+BaO components The mixture can significantly reduce the liquidus temperature of the glass, improve the melting performance of the glass and promote molding. Too low a total amount will lead to insufficient effect, and too high a total amount will cause crystallization of the glass. At the same time, adding ZnO can improve the melting performance. ZnO has a regular tetrahedral structure and good thermal conductivity. It can improve the melting quality of the glass, improve the uniformity of the glass, and improve the chemical stability and thermal stability of the glass. However, for the main components, ZnO is a low-amount element, so its proportion needs to be limited to achieve the optimal ratio to avoid problems such as too large a regular tetrahedral structure and insufficient other fillers, resulting in insufficient glass hardness. Therefore, (CaO+BaO) / ZnO is controlled to be 2.5-6, X2O3 / T iO2 is 0.1-7.5, and X2O3 is one or more of Bi2O3, La2O3, and Y2O3. Iron-titanium coloring is used to achieve amber color of the glass. However, the introduction of TiO2 and excessive alkaline earth metal content will cause crystallization of the glass. Therefore, one or more of Bi2O3, La2O3, and Y2O3 are introduced, and X2O3 / TiO2 is limited to 0.5-6.5 to improve the anti-crystallization performance and chemical stability of the glass and prevent the glass from crystallizing. It should be noted that;

[0045] Among them, SiO2 is introduced by low-iron silica sand, and its Fe2O3≤0.008wt%, particle size range: +0.6mm≤1%, 0.6mm-0.425mm<9.8%, 0.425mm-0.1mm≥85%, -0.1mm<5%, moisture content is 2%-5%, among which, the particle size range is to help the glass melt to provide a good molding and foundation; moisture is to provide a suitable redox atmosphere, which is helpful for glass coloring, Improve coloring uniformity, the working point (Tw) of amber glass viscosity is 103Pa·s ≤1005℃, the flame processing temperature (T2) of amber glass viscosity is 102Pa·s ≤1170℃, and the polishing temperature range ΔT of amber glass viscosity is 102.7-3.2Pa·s is 47℃-74℃, among which, by controlling the proportion of alkaline earth metal oxides, introducing Bi2O3, La2O3, and Y2O3, reducing the blowing molding temperature (T w , T2), and at the same time, the polishing temperature range is controlled at 47-74°C. This is because if the glass material is too long, the glass bottle cannot be formed, and if the glass material is too short, it will harden too quickly, causing the glass bottle to have faults and cracks. The color tone of amber glass is 4mm thick, Y is 17-29%, λd is 581-586, Pe>90%, and the alkali dissolution of amber glass is ≤0.08mL;

[0046] According to this composition, amber glass is prepared. The components and properties of the obtained glass samples of Example 1 to Example 6 and Comparative Examples 1 to Comparative Examples 2 are shown in Table 1. The high temperature viscosity is tested according to ASTM C-965 using a rotary high temperature viscometer, and the alkali dissolution is tested according to the particle method test standard in GBT 4771-2015, as follows:

[0047] Table 1 Components and properties of Examples 1 to 6 and Comparative Examples 1 to 2

[0048]

[0049]

[0050] In summary, it can be seen from Examples 1 to 8, Comparative Examples 1 and 2 that the glass, Y is 17-29%, λ d 581~586, Pe>90%, all are amber in color, and its viscosity characteristic point T w≤1005℃, T2≤1170℃, ΔT is 47-74℃, and alkali dissolution is ≤0.08mL; while Comparative Example 1 did not introduce Bi2O3, La2O3, and Y2O3, and Comparative Example 2 did not control the alkaline earth metal oxide components and proportions. The viscosity characteristic points and chemical stability of the two were worse than those of the comparative examples. It can be seen that the amber glass of the present invention reduces the molding temperature, ensures that the glass material property range is easy to be molded by blowing, reduces the difficulty of the blowing process, and greatly improves the chemical stability of the glass.

[0051] Embodiment seven:

[0052] Based on the above embodiments, Figure 1-Figure 7 As shown, the blow molding equipment in step S3 includes a workbench 1 and a blow molding assembly 9 detachably mounted on the workbench 1 through a third fixing frame 8, and also includes an intermittent feeding mechanism 2, which is arranged at the lower end of the workbench 1 and is used to drive a rotating table 5 arranged at the upper end of the intermittent feeding mechanism 2 to intermittently rotate and feed; a clamping mechanism 3, which is arranged above the workbench 1 and is used to drive two mutually matched molding molds 4 to close the mold, and the clamping mechanism 3 includes an automatic reset assembly 35 for automatic mold opening;

[0053] The clamping mechanism 3 also includes a fixed shaft 31 and an annular support frame 32 arranged on the fixed shaft 31. The fixed shaft 31 is fixedly arranged on the No. 1 rotating shaft 27. A plurality of slide rails 33 arranged in an annular array are arranged on the annular support frame 32. A No. 1 slider 34 is slidably connected to the inner side of each slide rail 33. A connecting shaft 36 is arranged on the upper end of the No. 1 slider 34. A connecting shaft 36 is rotatably connected to the upper end of the connecting shaft 36.

A connecting shaft 36 is rotatably connected to the upper end of the connecting shaft 36. The No. 1 connecting rod 37 and the No. 2 connecting rod 38 are staggered and rotatably connected. The upper ends of the No. 37 and No. 2 connecting rods 38 are fixedly connected to a No. 2 slider 39, the upper ends of the No. 2 sliders 39 are fixedly connected to the forming molds 4, and the forming molds 4 that cooperate with each other are symmetrically arranged; the clamping mechanism 3 also includes a fixed block 310 arranged on the upper surface of the workbench 1, and a cylinder 311 is detachably mounted on the fixed block 310, and the output end of the cylinder 311 is fixedly connected to a push block 312 that is arranged in close contact with the annular support frame 32 or the No. 1 slider 34, and the push block 312 has a curved surface close to the annular support frame 32 or the No. 1 slider 34.

[0054] Specifically, first, by adding molten glass liquid into the two forming molds 4 just above the cylinder 311, during this process, it is necessary to start the cylinder 311 to drive the push block 312 to push the No. 1 slider 34 to slide inside the slide rail 33, and the No. 1 slider 34 drives the connecting shaft 36 thereon to move, thereby making the No. 1 connecting rod 37 and the No. 2 connecting rod 38 rotate and the angle becomes smaller, and the No. 1 connecting rod 37 and the No. 2 connecting rod 38 respectively drive the No. 2 slider 39 thereon to slide inside the corresponding slide groove 51, and the No. 1 connecting rod 37 and the No. 2 connecting rod 38 move in opposite directions, thereby making the two mutually cooperating forming molds 4 come together, and then, by starting the cylinder 311 to drive the push block 312 to reset, multiple groups of forming molds 4 can be molded together by only one driving cylinder 311, compared with the traditional method of multiple groups of forming molds 4 requiring multiple drives, the production cost is greatly reduced.

[0055] The automatic reset assembly 35 includes a fixed seat 351 arranged on the slide rail 33, and a second rotating shaft 352 rotatably connected to the fixed seat 351, a limiting plate 353 is fixedly connected to the second rotating shaft 352, a limiting block 354 with an inclined bottom surface is arranged at the lower end of the limiting plate 353, and a limiting groove 341 used in conjunction with the limiting block 354 is arranged on the first slider 34, and a second reset spring 359 for resetting the first slider 34 is arranged on the slide rail 33, a triangular block 358 with an inclined top surface is arranged at the upper end of the limiting plate 353, and a No. 1 reset spring 355 is fixedly connected to the lower end of the limiting plate 353, and one end of the No. 1 reset spring 355 away from the limiting plate 353 is fixedly connected to the slide rail 33, and the automatic reset assembly 35 also includes a No. 1 fixed frame 356 fixedly connected to the workbench 1, and a baffle 357 used in conjunction with the triangular block 358 and arranged in an inclined manner is arranged on the No. 1 fixed frame 356.

[0056] Specifically, during the mold closing process of the two mutually cooperating forming molds 4, that is, when the push block 312 pushes the No. 1 slider 34 to slide inside the slide rail 33, since the limit block 354 below the limit plate 353 is inclined, the No. 1 slider 34 will lift up the limit plate 353 close to one end of the No. 1 slider 34 during its movement, until the limit block 354 moves to just above the limit groove 341, and under the action of the elastic force of the No. 1 return spring 355, the limit block 354 is stuck in the limit groove 341. At this point, it is realized that during the feeding until it passes through the blowing component 9, the blowing component 9 is the prior art and is only used for it. During the blowing process of the blowing component 9, the two mutually cooperating forming molds 4 always remain in a locked state, which is a The component 9 provides basic guarantee for the blowing of the glass raw materials inside the two forming molds 4; when the blowing component 9 blows the glass directly below it, the intermittent feeding mechanism 2 is started again to drive the rotating table 5 and the forming mold 4 above the rotating table 5 to rotate. During the rotation process, since there is an inclined triangular block 358 above the limit plate 353, the triangular block 358 will contact the baffle 357 and press the limit plate 353 downward away from the end of the first slider 34, so that the limit block 354 is disengaged from the inside of the limit groove 341, thereby realizing that after the blowing component 9 blows the glass inside the two forming molds 4, the two forming molds 4 are automatically opened, and the mold opening can be automatically performed without human or system control, and the operation is simple.

[0057] Embodiment eight:

[0058] On the basis of Example 7, the intermittent feeding mechanism 2 includes a driving shaft 21 rotatably connected to the lower end of the workbench 1, and a rotating disc 22 fixedly mounted on the driving shaft 21, the lower end of the rotating disc 22 is rotatably connected to a connecting frame 25, the end of the connecting frame 25 away from the rotating disc 22 is rotatably connected to a groove wheel 26, an eccentrically arranged lever 24 for driving the groove wheel 26 to rotate is arranged on the rotating disc 22, an incomplete disc 23 that can be used in conjunction with the groove wheel 26 is also arranged on the rotating disc 22, the groove wheel 26 is provided with a No. 1 rotating shaft 27 rotatably connected to the workbench 1, and the upper end of the No. 1 rotating shaft 27 is fixedly connected to a rotating table 5, and the rotating table 5 is provided with a slide groove 51 for sliding multiple No. 2 sliders 39; it also includes a driving mechanism for driving the driving shaft 21 to rotate.

It should be noted that the purpose of the incomplete disc 23 is to limit the rotation of the groove wheel 26 when the lever 24 is disengaged from the groove wheel 26 to prevent the groove wheel 26 from rotating on its own. The number of grooves on the groove wheel 26 can be specifically set according to the number of the upper forming molds 4 that cooperate with each other in pairs.
