Abstract
Description
Technical Field
[0001] This invention belongs to the field of glass forming technology, specifically referring to an energy-saving glass blowing forming device for glassware processing. Background Technology
[0002] In the glass blowing process, molten glass first flows from the furnace and is cut into droplets of a set weight by a feeder. These droplets are then precisely conveyed through a guide chute between the pressure head and the suction head. The pressure head presses the droplets vertically upwards, working in conjunction with the suction head to compress them into a uniform, cake-like shape. The suction head then carries the cake to the blown glass worktable. The blown glass head descends, blowing compressed air into the center of the cake, forming an eggplant-shaped or cylindrical bubble. Simultaneously, the mold closes, and continuous air blowing causes the glass to expand and adhere to the inner wall of the mold. After the mold opens, the semi-finished glassware is gripped by a robotic arm and fed into an annealing furnace. Gradual cooling eliminates thermal stress and prevents cracking. Finally, automatic cutting and edge grinding complete the surface treatment.
[0003] In mechanical blown glass production, mold temperature and blowing pressure are key factors affecting the uniformity of product thickness. Uneven mold temperature leads to differences in glass cooling rates; areas with higher temperatures exhibit greater glass fluidity and are easily stretched and thinned during blowing, while areas with lower temperatures cool faster and experience greater resistance, resulting in increased wall thickness. Furthermore, the blowing nozzle is typically fixed at the bottle neck. When the blowing pressure is too high, the bottom of the glass bulb experiences significant impact and thins, while the rim thickens due to insufficient pressure diffusion. Conversely, insufficient pressure leads to insufficient glass elongation, thinning of the rim, or even breakage, while also resulting in uneven wall thickness distribution. Summary of the Invention
[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide an energy-saving glass blowing apparatus for glassware processing, so as to at least partially solve the problems mentioned in the background art.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.
[0030] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.
[0031] To address the issue of uneven thickness in glassware during the blowing process caused by mold pressure and air blowing pressure, this invention provides an energy-saving glassware blowing device to make the glassware more uniform during the blowing process. The device mainly includes a forming mold 10, a driver 20, and an air blowing cylinder 30.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the forming mold 10 includes a first mold 10.1 and a second mold 10.2. After the first mold 10.1 and the second mold 10.2 are put together, a mold cavity 100 is formed inside. In the glass blowing process, the mold cavity 100 is mainly used to limit the shape of the glassware. Different shapes of glassware can be blown by using mold cavities 100 of different shapes.
[0033] Furthermore, the driver 20 is mounted on the worktable 01 and can drive the first mold 10.1 and the second mold 10.2 to engage or disengage from each other. The air blower 30 is mounted above the molding mold 10 and can blow air into the glass preform inside the mold cavity 100.
[0034] In some embodiments, a first positioning plate 011 and a second positioning plate 012 are fixedly arranged in parallel on the worktable 01. The driver 20 includes a cylinder 21 fixed on the second positioning plate 012. The output end of the cylinder 21 is provided with a telescopic rod 211. The end of the telescopic rod 211 is fixed with a connecting plate 22. The connecting plate 22 is driven by the cylinder 21 to move between the first positioning plate 011 and the second positioning plate 012. A guide rod 221 is fixed on the connecting plate 22. The guide rod 221 passes through the first positioning plate 011 and connects to the molding die 10.
[0035] When the first mold 10.1 and the second mold 10.2 need to be aligned, the cylinder 21 drives the telescopic rod 211 to extend. The telescopic rod 211 drives the connecting plate 22 to move forward. The connecting plate 22, through the guide rod 221, drives the first mold 10.1 and the second mold 10.2 to move closer to each other until the first mold 10.1 and the second mold 10.2 are aligned, and the glass preform in the mold cavity 100 is blown into shape. When the first mold 10.1 and the second mold 10.2 need to be separated, the cylinder 21 drives the telescopic rod 211 to retract. The telescopic rod 211 drives the connecting plate 22 to move backward. The connecting plate 22, through the guide rod 221, drives the first mold 10.1 and the second mold 10.2 to move away from each other until the first mold 10.1 and the second mold 10.2 are separated, and the formed glassware in the mold cavity 100 can be taken out.
[0036] Furthermore, the molding mold 10 has multiple sets of air guide chambers surrounding the outside of the mold cavity 100, and each set of air guide chambers is independently connected to an external air supply device. The air supply device is configured to introduce airflows of different temperatures into different sets of air guide chambers to adjust the temperature of different areas within the mold cavity 100.
[0037] In some embodiments, the mold cavity 100 includes, from top to bottom, a bottle mouth area, a curved transition area, a bottle body area, and a bottle bottom area. Multiple sets of air guide chambers are correspondingly arranged on the outside of the bottle mouth area, the curved transition area, the bottle body area, and the bottle bottom area. The air supply device is provided with a high-temperature air supply pipe and a low-temperature air supply pipe. The high-temperature air supply pipe and the low-temperature air supply pipe are connected in parallel to the multiple sets of air guide chambers through a switching valve, and the air guide chambers are connected to the high-temperature air supply pipe or the low-temperature air supply pipe through the switching valve.
[0038] The mold cavity 100 includes a first air guide cavity 101, a second air guide cavity 102, a third air guide cavity 103 and a fourth air guide cavity 104, which correspond to the bottle mouth area, the curved transition area, the bottle body area and the bottle bottom area, respectively.
[0039] Rapid cooling is required in the bottle neck area to ensure accuracy, while avoiding insufficient filling due to over-cooling. During the initial contact period, high-temperature gas is introduced into the first cavity to delay cooling. The temperature of the high-temperature gas is controlled at 400-450℃. After the bottle neck area is filled, low-temperature gas is switched to solidify and shape, thus completing the temperature control of the bottle neck area. The temperature of the low-temperature gas is controlled at 250-300℃.
[0040] In the transition zone of the curved surface, relatively low-temperature gas is introduced to the convex apex of the curved surface to prevent excessive extension, and the temperature is controlled at 320-350℃. For the concave valley of the curved surface, relatively high-temperature gas is introduced to compensate for flow lag, and the temperature is controlled at 380-420℃.
[0041] In the bottle body area, the thickness at the bottom and thinness at the top caused by gravity is counteracted by maintaining the balance of the axial temperature gradient. In the upper area near the bottle shoulder, the molding is delayed by heating compensation. The gas temperature in this area is set at 360-390℃. For the lower area near the bottom of the bottle, the thickening is suppressed by cooling. The gas temperature in this area is set at 300-330℃.
[0042] In the bottom area of the bottle, the glass arrives last and has the greatest flow resistance, and the temperature has dropped significantly. For the central load-bearing area, a medium-temperature airflow is introduced to maintain and ensure the glass thickness in this area. The medium-temperature airflow is set at 340-370℃. For the edge corner area of the bottom of the bottle, ultra-high temperature gas is introduced to enhance the fluidity of the glass and fill the corner area. The temperature of the ultra-high temperature gas is set at 450-500℃.
[0043] like Figure 4 As shown, the same air guiding cavity is constructed as a semi-annular channel on the first mold 10.1 and the second mold 10.2 respectively. The semi-annular channels on the first mold 10.1 and the second mold 10.2 are joined together to form a sealed annular air guiding cavity. The first mold 10.1 and the second mold 10.2 are each provided with a first air guiding connector 11 that communicates with the semi-annular channel. In the same air guiding cavity, the first air guiding connector 11 on the first mold 10.1 is configured as the air inlet end, and the first air guiding connector 11 on the second mold 10.2 is configured as the air outlet end.
[0044] In some embodiments, a connecting pipe 110 is provided between the air guiding cavity and the first air guiding connector 11. The first end of the connecting pipe 110 is connected to the first air guiding connector 11, and the second end of the connecting pipe 110 is connected to the middle position of the semi-annular cavity.
[0045] The gas supply device supplies gas to the first gas connector 11 through high-temperature and low-temperature pipelines. The temperature of the airflow is controlled by a proportional valve at the connection between the two pipelines and the first gas connector 11. When the set airflow enters the connecting pipeline 110 from the first gas connector 11, the airflow in the connecting pipeline 110 enters the middle position of the semi-annular cavity, and then flows evenly to both sides, covering the entire annular gas guide cavity, so that the set area is filled with airflow at the set temperature. In this way, the temperature of different areas in the first mold 10.1 and the second mold 10.2 is controlled, and the glass is evenly distributed by controlling the resistance to its extension during the glass blowing process.
[0046] Currently, when blowing air into the glass, the position of the air inlet is fixed, usually at the bottle opening. After blowing gas at a set pressure into the glass, the glass expands and fills the mold cavity by 100 under pressure. However, constant pressure cannot guarantee uniformity.
[0047] Furthermore, the air blowing tube 30 includes an air blowing duct 33 connected to an external air supply device. The air blowing duct 33 is telescopically disposed within the mold cavity 100, and the position of the air outlet of the air blowing duct 33 within the mold cavity 100 can be adjusted. By adjusting the position of the air outlet inside the glass, pressure can be dynamically and locally controlled. The outlet can be moved to the most difficult-to-fill area (such as a thick-walled low-temperature area or a deep recess), shortening the airflow path and increasing the effective driving pressure in that area. Targeted pressurization can be applied to areas with high resistance to prevent poor filling in distant areas due to pressure attenuation. Combined with the temperature adjustment on the forming mold 10, local fluidity can be improved, making the glassware more uniform in wall thickness during the blowing process.
[0048] like Figure 2 , Figure 5 and Figure 6 As shown, the air blowing conduit 33 includes a first conduit 331 and a second conduit 332. The first conduit 331 is fixed relative to the bottle mouth position, and a sealing plug 35 is provided on the outside of the first conduit 331 to seal the space inside the bottle. The second conduit 332 is telescopically disposed inside the first conduit 331. The air inlet end of the second conduit 332 is connected to an external air supply device, and the air outlet end of the second conduit 332 is located inside or extends out of the first conduit 331.
[0049] Furthermore, the head end of the second conduit 332 is provided with a first air guide hole 3320, and the outer wall of the second conduit 332 is provided with a plurality of evenly distributed second air guide holes 3321. The airflow direction of the first air guide hole 3320 is the axial direction, and the airflow direction of the second air guide hole 3321 is perpendicular to the axial direction. The airflow inside the second conduit 332 can be discharged through the first air guide hole 3320 and the second air guide hole 3321.
[0050] Furthermore, the end of the first conduit 331 is provided with a stepped groove 3310, which can guide the airflow from the second air guide hole 3321 located inside the stepped groove 3310 to the axial direction of the second conduit 332.
[0051] In some embodiments, the second conduit 332 includes a first position and a second position inside the first conduit 331. In the first position, the end of the second conduit 332 is inside the first conduit 331. At this time, the second conduit 332 can only output airflow in the axial direction from the first air guide hole 3320 at its end. Even if there is airflow output from the second air guide hole 3321, it will be output in the axial direction after entering the stepped groove 3310.
[0052] In the second position, the second conduit 332 extends out of the first conduit 331, and can not only export airflow in the axial direction through the first air outlet 3320, but also export airflow perpendicular to the axial direction through the second air outlet 3321. By exporting airflow from different regions, pressure is provided to different positions inside the glass, causing the glass to extend evenly in each region.
[0053] In some embodiments, the air blower 30 further includes a cylinder 31 and a linear actuator 34 disposed on the cylinder 31. The linear actuator 34 includes a first actuator 341 and a second actuator 342. The first actuator 341 and the second actuator 342 are respectively used to drive the first conduit 331 and the second conduit 332 to move in the axial direction. A clamp 32 is hingedly mounted on one end of the cylinder 31 near the air blower 33. The clamp 32 is driven to clamp the glass piece.
[0054] Furthermore, the interior of the cylinder 31 is provided with a first drive rod 3411 and a second drive rod 3421. The first drive rod 3411 is located at the output end of the first driver 341, and the second drive rod 3421 is located at the output end of the second driver 342. The other end of the first drive rod 3411 is fixedly connected to the first conduit 331, and the other end of the second drive rod 3421 is fixedly connected to the second conduit 332.
[0055] Both the first actuator 341 and the second actuator 342 are electrically controlled, enabling more precise movement. The first actuator 341 drives the first drive rod 3411 to reciprocate in the axial direction to drive the position of the first conduit 331. Initially, the first conduit 331 is in a retracted position. When air needs to be blown into the glass bottle, the first actuator 341 first drives the first conduit 331 to a fixed position at the mouth of the glass bottle and inserts the sealing plug 35 into the mouth of the bottle to seal the internal space. Then, air is blown into the bottle through the second conduit 332, which is connected to the second air connector 311 via the connecting hose 3111. As air is blown, the second actuator 342 drives the second drive rod 3421 to move, causing the second conduit 332 to extend out of the first conduit 331. Thus, air can be guided not only in the axial direction but also at multiple height positions in the axial direction, providing pressure to different positions inside the glass and promoting uniform expansion of the glass in various areas.

[0057] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
