Description

Technical Field

[0001] This invention relates to the technical field of bottle-making machines, and in particular to a thick-bottomed glass bottle-making machine that uses a pre-molded heating mold. Background Technology

[0002] Thick-bottomed, irregularly shaped glass bottles have broad application prospects in many fields such as beauty and skin care, food, wine, creative gifts, health products and specialty medicines. Their unique design and diverse shapes make them important tools for enhancing product appeal and market competitiveness.

[0003] Currently, the production of thick-bottomed and irregularly shaped glass bottles mainly uses rotary machines and manual machines. For example, the invention patent application with publication number CN109437529B discloses a method for making a thick-bottomed crystal glass cup. First, a thin-bottomed cup blank is processed, and the bottom of the thin-bottomed cup blank is processed into a regular cone shape. Then, the cone shape is processed into a thick bottom by a pushing method. Finally, the thick bottom is obtained by annealing and heat preservation.

[0004] The preforms (or tube preforms) blown by the row-type bottle making machine are transferred to the rotary machine for secondary processing and shaping. During the preform transfer process, heat is lost, and secondary heating is required during the thick-bottom processing of glass bottles, resulting in a large amount of heat loss. Moreover, the row-type bottle making machine is limited by various factors such as spatial layout, and the types of bottles it can produce are relatively limited. How to promote the production of more types of thick-bottom and irregular-shaped bottles on the row-type bottle making machine has become a problem that needs to be solved. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] Example 1 Please refer to Figures 1-6 A thick-bottom glass bottle making machine with a pre-formed mold heating system includes a frame 1, a pre-formed mold forming mechanism, a flipping and transferring mechanism, and a thick-bottom forming mold mechanism. The pre-formed mold forming mechanism is used for shaping the bottle mouth of the glass preform and for the initial forming of the inner core cavity. The flipping and transferring mechanism is used for transferring the pre-formed bottle preform to the thick-bottom forming mold mechanism. The thick-bottom forming mold mechanism includes a first clamping mold 2, a bottom mold pushing assembly, and an internal blowing sealing and heating assembly. The first clamping mold 2 has a forming cavity. The bottom mold pushing assembly includes a bottle bottom push mold 3 that is slidably mounted on the frame 1 and fits into the bottom of the forming cavity, and a lifting pusher 4 that provides power for the vertical movement of the bottle bottom push mold 3. The internal blowing sealing and heating assembly is used for blowing the bottle preform and for internal heating and bottom positioning of the formed bottle. In this embodiment, the pre-formed mold forming mechanism, the flipping and transferring mechanism, and the thick-bottom forming mold mechanism are all mounted on the frame 1. The lifting pusher 4 can be a pneumatic cylinder or other equivalent component that drives the bottle bottom push mold 3 to move vertically.

[0042] For details, please refer to Figure 11The initial mold forming mechanism includes a second clamping mold 25, which has an initial mold cavity. The flipping and transferring mechanism includes a shaft 26 rotatably mounted on the frame 1, an L-shaped support arm 27 fixedly connected to the shaft 26, and a flipping drive 29 that provides power for the rotation of the shaft 26. The L-shaped support arm 27 has a bottle mouth mold groove 28 corresponding to the initial mold cavity. An air blowing head mechanism 30 corresponding to the bottle mouth mold groove 28 is mounted on the frame 1. The air blowing head mechanism 30 is used for inner mouth forming of the bottle mouth and introducing compressed air into the initial mold cavity of the initial bottle. Furthermore, both the first clamping mold 2 and the second clamping mold 25 include mechanical clamps and double-opening molds mounted on the mechanical clamps. The flipping drive 29 uses a drive cylinder 33 and a gear rack. The drive cylinder 33 provides power for the rotation of the shaft 26 through the gear rack. Other equivalent components that drive the shaft 26 to rotate can also be used. The air blowing head mechanism 30 can use existing technology.

[0043] For details, please refer to Figure 1 and Figure 8 It also includes a second rotary lifter 31, a funnel 32 mounted on the second rotary lifter 31, and a heating and flame-spraying mechanism. The heating and flame-spraying mechanism includes a drive cylinder 33 fixedly mounted on the second rotary lifter 31 and a heating nozzle 34 mounted on the drive cylinder 33. Furthermore, the heating nozzle 34 is connected to an external gas and oxygen supply source.

[0044] For details, please refer to Figure 1 and Figure 8 It also includes a third rotary lifter 35 and a deflation mechanism 36 mounted on the third rotary lifter 35; further, the deflation mechanism 36 is connected to an external pressurized air source; the deflation mechanism 36 can adopt existing technology, specifically refer to the deflation mechanism 36 disclosed in CN205528382U and the deflation mechanism 36 disclosed in the bottle making machine with the deflation mechanism 36, which will not be described further here.

[0045] Initially, the second rotary lifter 31 moves the funnel 32 above the second clamping molding die 25. Molten glass material supplied externally is introduced into the primary mold cavity through the funnel 32. The third rotary lifter 35 moves the venting mechanism 36 above the funnel 32, pressing the glass material in the primary mold cavity into the bottle neck mold groove 28. Venting ends, the venting mechanism 36 is lifted, the funnel 32 is removed, and the venting mechanism 36 falls back down and covers the second clamping molding die 25. This process is repeated on the upper end of the second clamping molding die 25. The mouth is sealed, the air blowing head mechanism 30 actuates and extends into the middle of the glass material in the bottle mouth mold groove 28, the bottle mouth of the glass bottle is formed, the air blowing head mechanism 30 blows air into the glass material, so that a core cavity is formed inside the glass material, the glass bottle preform is formed, after the glass bottle preform has initially cooled and solidified, the air blowing head mechanism 30 is pushed out, the air blowing mechanism 36 is reset, the second clamping molding mold 25 is opened, because the bottle mouth of the preform is in a state of thermal expansion, the bottle mouth of the preform and the bottle mouth mold groove 28 are interference fit, the second rotary lifter 31 drives the heating and flame-spraying mechanism to move to the bottle mouth mold groove 28. Above the bottom of the preform, the output end of the drive cylinder 33 extends, and the heating nozzle 34 approaches the bottom of the preform. The flame generated by the combustion of gas at the heating nozzle 34 heats the bottom of the preform. Before the preform is transferred to the molding cavity, the internal temperature of the preform is higher than the external temperature. After reheating, the internal and external temperatures of the preform are similar, which can effectively prevent wrinkles in the molded bottle caused by uneven internal and external temperatures, thus improving the quality of the molded bottle. Heating also provides temperature protection for the subsequent blow molding of the preform in the molding cavity. In another embodiment, the heating and flame mechanism can also heat the initial mold. The cavity is heated to increase the temperature inside the initial mold cavity, reducing the initial heat loss of the molten glass material and allowing the glass material to be blown into the preform more smoothly. The heating and spraying mechanism is equipped with a switching valve, which can also blow compressed air to the bottle mouth of the preform to accelerate the cooling of the bottle mouth and allow the bottle mouth of the preform to solidify and form quickly. The flipping drive 29 drives the shaft 26 and the support arm to rotate 180 degrees, so that the preform is transferred into the forming mold cavity, preparing for the subsequent preform blowing and thick bottom processing.

[0046] For details, please refer to Figures 2-6 as well as Figures 9-10 The internal blowing sealing and heating assembly includes a first rotary lifter 5, an air distribution housing 6 mounted on the first rotary lifter 5, a hollow shaft 7 mounted on the air distribution housing 6, a sealing and limiting component mounted at the bottom of the hollow shaft 7, and multiple heating elements evenly distributed around the lower part of the hollow shaft 7. The air distribution housing 6 has a first cavity 8, and the hollow shaft 7 has a port 9 communicating with the first cavity 8. An air supply nozzle 10 communicating with the interior of the hollow shaft 7 is mounted at the bottom of the hollow shaft 7. Furthermore, the first cavity 8 is connected to an external pressurized air source. The sealing and limiting component can be a cylindrical sealing plug made of metal, with its bottom lower than the bottom of the air supply nozzle 10. The heating elements can be electric heating elements or other equivalent components with heating effects.

[0047] During the preform blowing process in the first clamping molding mold 2, the first rotary lifter 5 moves the air distribution housing 6 above the first clamping molding mold 2 and then downwards, causing the sealing and limiting component to seal the preform opening. External compressed gas or oxygen can be injected into the preform through the first cavity 8, the port 9, the hollow shaft 7, and the air supply nozzle 10. Under pressure, the preform is blown into shape within the molding cavity. Subsequently, the first rotary lifter 5 moves the air distribution housing 6 downwards until the sealing and limiting component extends into the lower preset position inside the molded bottle (seal). The distance between the blocking and limiting component and the inner bottom of the formed bottle ultimately determines the thickness of the formed bottle. According to production needs, the distance between the two can be appropriately adjusted by designing the lower limit position of the blocking and limiting component. The heating component heats the bottom of the bottle, while the lifting pusher 4 pushes the bottom mold 3 upward. The bottom of the glass bottle gradually bulges upward from the edge to the center. The blocking and limiting component contacts and limits the upper part of the molten glass bottom in the rising state. The material in the middle of the bottom of the bottle is dispersed to the surrounding area, so that the bottom of the glass bottle is gradually thickened, thus achieving the thickening treatment of the bottom of the formed glass bottle.

[0048] More specifically, in another embodiment, the blocking and limiting member adopts the following specific structure: Please refer to Figure 6 and Figure 9 The sealing and limiting components include multiple conical ramp seats 11 evenly distributed circumferentially at the bottom of the hollow shaft 7, ramp blocks 12 slidably mounted on the conical ramp seats 11, L-shaped arc-shaped components 13 fixedly mounted on the ramp blocks 12, and a driving component that provides power for the retraction and extension of the L-shaped arc-shaped components 13. The driving component includes a plunger 14 slidably mounted up and down inside the hollow shaft 7, a mounting plate 15 fixedly connected to the plunger 14, multiple tension springs 16, and multiple transmission rods 17. The mounting plate 15 is connected to the bottom of the hollow shaft 7 through the tension springs 16. One end of the transmission rod 17 is hinged to the corresponding ramp block 12, and the other end of the transmission rod 17 is hinged to the mounting plate 15. The plunger 14 has an air supply channel 18 communicating with the interior of the hollow shaft 7, and an air supply nozzle 10 is installed at the end of the plunger 14. A sealing valve 19 is installed at the connection between the 4 and the gas supply nozzle 10; furthermore, the sealing valve 19 is a plug valve, and the actuation drive mechanism of the sealing valve 19 is installed on the upper part of the hollow shaft 7. The actuation drive mechanism can be an electric telescopic cylinder or other equivalent components that can drive the plug valve to open and close; the sealing valve 19 can also be a high-temperature resistant remote electric control valve, etc.; after multiple L-shaped arc-shaped parts 13 are closed, they form a cylindrical shell with a bottom seal. The bottom of the cylindrical shell is provided with a through hole that fits with the gas supply nozzle 10. When gas is injected into the preform, the through hole and the gas supply nozzle 10 are in a sealed state. The joints of multiple L-shaped arc-shaped parts 13 and the contact points with the gas supply nozzle 10 are polished or treated with sealing materials to improve the overall sealing performance of the cylindrical shell after closure.

[0049] During the preform blowing process, the sealing valve 19 is in the open state. Under the tension of the tension spring 16, the L-shaped arc parts 13 converge into a cylindrical shell shape. The cylindrical shell fits into the bottle mouth of the preform. After closing, the cylindrical shell can seal the bottle mouth to reduce the leakage of compressed air or oxygen, ensuring the pressure value inside the preform, so that the preform can be successfully blown into shape. When the bottle bottom is thickened, the sealing valve 19 blocks the air supply channel 18, the pressure inside the hollow shaft 7 increases, and the plunger 14 is pushed down, passing through the mounting plate 15 and the transmission rod. After transmission 17, the ramp 12 slides down at the conical ramp seat 11, and the L-shaped arc member 13 moves down and moves away from the center of the hollow shaft 7. The bottom of the L-shaped arc member 13 forms a downward and outward pressing pressure on the middle of the convex bottle bottom, reducing the flow interference of the L-shaped arc member 13 on the molten glass material at the bottom of the bottle, so that the molten glass material is more evenly distributed from the middle to the surrounding area, improving the uniformity of the thickness of the bottle bottom. In this embodiment, the thickness of the bottom of the formed bottle is the distance between the bottom of the dispersed L-shaped arc member 13 and the bottle bottom push mold 3.

[0050] Further optimizations to the heating element are needed; please refer to [link / reference needed]. Figures 9-10 It also includes multiple gas supply pipes 20 and multiple oxygen supply pipes 21. The heating element is a flamethrower 22, which is evenly distributed around the bottom of the mounting plate 15. The gas distribution housing 6 has a second cavity 23. One end of the gas supply pipe 20 is connected to the gas inlet of the flamethrower 22, and the other end is connected to the second cavity 23. One end of the oxygen supply pipe 21 extends into the gas supply channel 18 of the plunger 14, and the other end is connected to the oxygen inlet of the flamethrower 22. Furthermore, each flamethrower 22 is located between two adjacent L-shaped arc-shaped parts 13, and the flamethrower 22 has a built-in spark plug or other automatic igniter. The upper part of the gas supply pipe 20 should have space to allow the plunger 14 to rise and fall. The extension allowance; more specifically, the flame-emitting end of the flame gun 22 is directed towards the junction of the bottle bottom and the bottle body; in another embodiment, a permanent flame can also be used at the flame gun 22 to continuously heat the L-shaped arc member 13; it should be noted that the partial pressure of oxygen entering the flame gun 22 should not cause excessive interference to the pressure value inside the hollow shaft 7, and the oxygen pressure inside the hollow shaft 7 should ensure that the plunger 14 is in a downward moving state; the oxygen pressure value inside the hollow shaft 7 can be adjusted by an external flow valve, etc., more specifically, by intermittently controlling the air pressure value inside the hollow shaft 7 by an external flow valve, the plunger 14 moves up and down repeatedly, so as to press the molten glass at the bottom of the bottle from the center to the surrounding area through the L-shaped arc member 13.

[0051] For details, please refer to Figures 2-7The hollow shaft 7 is rotatably mounted on the gas distribution housing 6, and the gas distribution housing 6 is equipped with a rotary drive 24 that provides power for the rotation of the hollow shaft 7. Furthermore, the rotary drive 24 adopts a motor and a gear set. The motor provides power for the rotation of the hollow shaft 7 through the gear set. The port 9 on the hollow shaft 7 is located in the first cavity 8. The input end of the gas supply pipe 20 passes through the hollow shaft 7 and communicates with the interior of the second cavity 23.

[0052] The heating element is a flamethrower 22, which supplies pressurized gas from the outside through the second cavity 23 and the gas supply pipe 20 into the flamethrower 22. Oxygen is supplied through the first cavity 8, the hollow shaft 7, and the oxygen supply pipe 21. The gas is ignited by the built-in spark plug, so that the combustion flame heats the bottom of the formed bottle. The flame can improve the heating uniformity of the bottle bottom. Heating inside the bottle can reduce heat loss to the outside, and also reduce the escape of gas and oxygen. The heat melting treatment of the bottle bottom can be achieved with less fuel, which is more energy-saving and environmentally friendly. In this embodiment, oxygen can also be used for blowing the preform, so that an oxygen-rich environment is formed inside the bottle to ensure complete combustion of gas.

[0053] The hollow shaft 7 is driven to rotate by the rotating drive component 24, so that each L-shaped arc component 13 rotates while limiting the bottom of the bottle, which further improves the uniformity of the dispersion of the material at the bottom of the bottle and improves the smoothness of the inner wall of the molded thick bottle. At the same time as the hollow shaft 7 rotates, the flame sprayed by the flame jet 22 can also uniformly heat the bottom of the bottle.

[0054] For details, please refer to Figure 1 , Figure 12 It also includes a fourth rotary lifter 37 and a bottle clamping mechanism 38 mounted on the fourth rotary lifter 37; further, the bottle clamping mechanism 38 is equipped with mechanical clamps for clamping the formed bottles; the first rotary lifter 5, the second rotary lifter 31, the third rotary lifter 35 and the fourth rotary lifter 37 all include a cylinder 39, a piston 40 that slides up and down and rotates in the cylinder 39, and a lifting rotary column 41 that is fixedly connected to the piston 40 and slidably sealed to the cylinder 39. The bottom of the cylinder 39 is provided with a steering guide groove 42, and a roller 43 that moves along the steering guide groove 42 is rotatably mounted on the lifting rotary column 41.

[0055] After the thick-bottomed glass bottle is fully formed, the first clamping mold 2 is opened, and the fourth rotary lifter 37 drives the bottle clamping mechanism 38 to rotate and move down. The bottle clamping mechanism 38 clamps the thick-bottomed glass bottle and then transfers it. Each rotary lifter moves up and down under the action of external hydraulic or pneumatic pressure on the piston 40. Under the action of the steering guide groove 42 and the roller 43, the rotation drive of the lifting rotary column 41 is realized to achieve the lifting and rotating action. The lifting and rotating drive can be realized without the need to add a rotary drive, which further reduces the space occupied by the equipment and provides a basic guarantee for the row-type bottle making machine to process thick-bottomed or irregularly shaped bottles.

[0056] For details, please refer to Figure 1 It also includes a gas supply pipeline system 44, which provides compressed air, natural gas and oxygen to the flamethrower 22 and the heating nozzle 34. Furthermore, the gas supply pipeline system 44 is connected to the first cavity 8 and the second cavity 23 inside the gas distribution housing 6 and the air inlet of the heating nozzle 34 through pipelines. The gas supply pipeline system 44 is equipped with necessary valves such as flow valves, mixers, pressure gauges and switching valves to adjust the supply flow rate and pressure of compressed air, natural gas and oxygen.

[0057] The usage process of the thick-bottomed glass bottle making machine with initial mold heating provided by this invention is as follows: Receiving: Before the molten glass droplets flow out from the external turning groove, the funnel 32 has already covered the upper part of the second clamping molding die 25. The droplets falling vertically from the turning groove fall into the primary mold cavity through the funnel 32. The inner hole of the funnel 32 is also a channel for air to escape.

[0058] Air compression: The air compression mechanism 36 supplies air from above the second clamping molding die 25 to compress the glass material into the bottle mouth mold groove 28, so that the bottle preform bottle mouth is fully formed in the bottle mouth mold groove 28.

[0059] Back-blowing: After the air blowing ends, the air blowing mechanism 36 is raised, the funnel 32 is moved away, and the air blowing mechanism 36 is lowered again to cover the second clamping molding mold 25, which is used to seal the bottom during back-blowing; the air blowing head mechanism 30 introduces compressed air into the core cavity formed at the bottle mouth during air blowing, and the glass material is initially blown in the primary mold cavity.

[0060] Preform reheating and transfer: The solid glass material at the bottom of the preform is reheated by a heating and flame mechanism, and the heated preform is transferred to the first clamping molding mold 2 by a flipping and transfer mechanism.

[0061] Forward blowing and bottle bottom thickening treatment: The internal blowing sealing and heating component first seals the bottle mouth of the preform and then blows the preform into shape. Then it enters the inside of the formed bottle and heats and limits the bottom of the formed glass bottle. The bottom mold pushing component pushes the heated bottom of the bottle. The bottom of the bottle is gradually compressed into a thick bottom by the bottom pushing mold 3 and the internal blowing sealing and heating component.

[0062] Clamping out: After the molded bottle cools down, the clamping mechanism 38 moves to the first clamping mold 2, the first clamping mold 2 opens, the clamping mechanism 38 clamps the product and turns it out, places the product on the stop plate of the external bottle conveyor and conveys it to the next process.
