Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass bottle processing, in particular to a glass wine bottle blow molding process. BACKGROUND

[0002] The "glass wine bottle" is a container made of glass material for containing wine liquid. The glass wine bottle has the characteristics of good chemical stability, easy sealing, air tightness, and the ability to maintain the original quality and flavor of the wine, etc. Blow molding is a common manufacturing process for glass wine bottles.

[0003] In the prior art, when the glass wine bottle is blow molded, the molten glass material is dropped into the molding station and preliminarily kneaded into a "glass material ball". Then, slow air is blown into the blow pipe to form a small air cavity inside, and the "glass material ball" is blown into a "glass bubble" (similar in shape to a small lantern, loose in shape). Then the glass bubble is transferred to the molding mold, and air is blown into the glass bubble until the molten glass material completely adheres to the inner wall of the mold, accurately replicating the shape of the mold, and finally the finished glass bottle is obtained after demolding and cooling processes.

[0004] In such a glass wine bottle blow molding process, the glass bubble is usually transferred to the molding mold by clamping equipment such as a bottle mouth clamp. However, such a transfer method has high precision requirements for the size, clamping force and transfer trajectory of the clamping equipment, and the equipment debugging cost is high. In addition, since the blown glass bubble is loose in shape, the transfer process can cause clamping marks on the "glass bubble", and the clamping equipment also has the problem of large installation space occupation, so further improvement is needed. SUMMARY

[0005] In order to improve the transfer convenience of the glass bubble, the present application provides a glass wine bottle blow molding process.

[0006] The glass wine bottle blow molding process provided by the present application adopts the following technical scheme: A glass wine bottle blow molding process, comprising the following steps: S1, taking material and breaking down, placing the glass raw material in the initial bubble mold to obtain a glass material ball; S2, blowing the initial bubble, blowing air into the glass material ball to obtain a glass bubble; S3, molding and shaping, placing the glass bubble in the molding mold and blowing air into the glass bubble to obtain a glass wine bottle; S4, demolding and cooling; wherein the blow molding of the glass wine bottle is carried out in a workbench, the initial bubble mold and the molding mold are both arranged on the workbench, and the initial bubble mold is located above the molding mold; the initial bubble mold and the molding mold are rotationally connected by a turnover shaft, and the turnover shaft is connected with a blow pipe.

[0007] By adopting the above technical solution, during the production of glass bottles, molten glass is dripped into the initial bubble mold to form a glass mass. Air is blown into the glass mass through a blowpipe, creating an air cavity inside, thus forming a glass bubble. Next, the initial bubble mold and the forming mold are opened, driving the rotating shaft to rotate, causing the blowpipe to flip the glass bubble downwards. Then, the forming mold is closed, and air continues to be blown into the glass bubble through the blowpipe until the molten glass completely adheres to the inner wall of the forming mold, ultimately producing the glass bottle. The initial bubble mold and the forming mold share a blowpipe, and the flipping of the blowpipe facilitates the transfer of the glass bubble, greatly improving the ease of transfer and reducing the overall space occupied and the possibility of indentations during glass bubble transfer.

[0008] Optionally, the initial foaming mold includes two initial foaming half-molds, and the forming mold includes two forming half-molds. The two initial foaming half-molds and the two forming half-molds are arranged correspondingly, and each initial foaming half-mold is connected to the corresponding forming half-mold. The worktable is provided with opening and closing components for driving the two forming half-molds to move closer or further apart from each other.

[0009] By adopting the above technical solution, the two molding half molds are driven to move closer or further apart by the opening and closing components, so as to realize the synchronous opening and closing of the molding mold and the initial foaming mold, thereby reducing the layout of the overall equipment drive source.

[0010] Optionally, the molding half-mold is connected to a sliding bar, and the opening and closing component includes a driving cylinder. The cylinder body of the driving cylinder is connected to the worktable, and the piston rod of the driving cylinder is connected to the sliding bar.

[0011] By adopting the above technical solution, the extension and retraction of the piston rod of the drive cylinder is used to drive the sliding strip to slide, thereby realizing the opening and closing of the molding mold and the initial foaming mold.

[0012] Optionally, a linkage shaft is rotatably mounted on the worktable, and the linkage shaft is circumferentially linked with the tilting shaft; one end of the linkage shaft is connected to a first gear, and a first rack is slidably mounted on the worktable, and the first gear and the first rack mesh and transmit power; the worktable is provided with a drive assembly that drives the first rack to slide back and forth.

[0013] By adopting the above technical solution, the linkage shaft and the tilting shaft are circumferentially linked, so that when the linkage shaft rotates, it can drive the tilting shaft to rotate synchronously. The meshing transmission between the first gear and the first rack, and the reciprocating sliding of the first rack by the drive component, can control the forward and reverse rotation of the first gear. That is, the linkage shaft can drive the tilting shaft to rotate forward and reverse, thereby enabling the blowpipe to switch between the initial foaming mold and the forming mold, improving the overall operational convenience of the structure.

[0014] Optionally, the drive assembly includes a drive shaft, a drive frame, and a drive component. The drive shaft is rotatably mounted on the worktable and is connected to a drive column, which is eccentrically positioned relative to the drive shaft. The drive frame is mounted on a first rack and has a drive groove for the drive column to be inserted into. The drive component is mounted on the worktable to drive the drive shaft to rotate.

[0015] By adopting the above technical solution, when the orientation of the blowpipe is switched, the drive shaft is rotated by the drive component, causing the drive column to "revolve" around the central axis of the drive shaft. The drive column drives the drive frame of the first rack to slide through the inner wall of the drive groove, thereby driving the first gear to rotate, causing the flip shaft to rotate, realizing the switching of the orientation of the blowpipe, and improving the operational convenience of the overall structure.

[0016] Optionally, the driving component includes a second gear and a second rack. The second gear is coaxially disposed at one end of the driving shaft, and the second rack is slidably mounted on the worktable. The second gear and the second rack mesh and drive each other. One end of the second rack is connected to a sliding bar.

[0017] By adopting the above technical solution, when the initial mold or the forming mold opens, the two forming half molds are driven to move away from each other, so that the sliding bar can drive the second rack to slide. Under the meshing of the second gear and the second rack, the drive shaft is rotated, which in turn drives the flipping shaft to rotate to switch the direction of the blowpipe.

[0018] Optionally, the second rack is connected to a push-pull bar, which has a through groove for the sliding bar to pass through; the sliding bar is provided with a first push block and a second push block, which are arranged at intervals along the length of the sliding bar, and the distance between the first push block and the second push block is greater than the thickness of the push-pull bar.

[0019] By adopting the above technical solution, when the initial bubble mold or the forming mold is closed, the sliding bar pushes the push-pull bar through the first push block, thereby pulling back the second rack, and at this time there is a gap between the second push block and the push-pull bar. When the initial bubble mold or the forming mold is opened, the two forming half molds are driven away from each other. Only after the second push block slides to abut against the push-pull bar can the second rack be pushed. The effect is that the initial bubble mold and the forming mold can be opened first, and then the second rack can be pushed to drive the flipping shaft to rotate. This achieves the sequential opening of the initial bubble mold and the forming mold and the flipping of the flipping shaft, avoiding the possibility of interference between the glass bubble and the initial bubble mold or the forming mold during the mold opening process.

[0020] Optionally, the second gear is provided with a rotating sleeve, which is rotatably mounted on the outer peripheral wall of the drive shaft; a one-way rotating component is provided between the rotating sleeve and the drive shaft, and when the two molding half molds move away from each other, the one-way rotating component forces the rotating sleeve and the drive shaft to move in a circumferential direction; when the two molding half molds move closer to each other, the rotating sleeve and the drive shaft are disengaged.

[0021] By employing the above technical solution, a one-way rotating component is installed between the rotating sleeve and the drive shaft. When the two molding halves are driven away from each other, the sliding bar, through the meshing of the second rack and the second gear, drives the drive shaft to rotate, thereby rotating the flipping shaft and switching the direction of the blowpipe. Conversely, when the two molding halves approach each other, the rotating sleeve and the drive shaft disengage. That is, when the sliding bar pulls the second rack, driving the second gear to rotate, the drive shaft cannot rotate, thus keeping the blowpipe stationary during mold closing. This achieves precise switching of the blowpipe's direction and improves the overall ease of operation.

[0022] Optionally, the workbench is provided with an air blowing seat, which has a first air blowing chamber, a second air blowing chamber, and a connecting chamber. The inlet end of the first air blowing chamber, the second air blowing chamber, and the blowpipe are all connected to the connecting chamber. A first push plate is slidably installed in the first air blowing chamber, and a second push plate is slidably installed in the second air blowing chamber. The air blowing seat is provided with a first pushing member for driving the first push plate to slide and a second pushing member for driving the second push plate to slide.

[0023] By employing the above technical solution, when the blowpipe is flipped to face the initial bubble mold, the first pusher drives the first push plate to slide towards the side closer to the connecting cavity, thereby squeezing the air in the first blowing chamber into the connecting cavity and blowing it outwards through the blowpipe, causing the glass material in the initial bubble mold to form a glass bubble. After the glass bubble is transferred to the forming mold, the second push plate is driven to slide towards the side closer to the connecting cavity, thereby squeezing the air in the second blowing chamber into the connecting cavity and blowing it outwards through the blowpipe, causing the glass bubble to continue expanding to form a glass bottle. By utilizing the spatial size of the first and second blowing chambers, the amount of air blown into the initial bubble mold or forming mold can be controlled, achieving precise control of the air pressure.

[0024] Optionally, the inner wall of the connecting cavity is provided with a first connecting channel and a second connecting channel, the first connecting channel connecting to the first blowing chamber and the second connecting channel connecting to the second blowing chamber; a switching strip is slidably installed in the connecting cavity, one end of the switching strip passing through the blowing seat and connected to the first rack, when the blowing pipe is facing the initial foaming mold, the switching strip opens the first connecting channel and closes the second connecting channel, when the blowing pipe is facing the forming mold, the switching strip opens the second connecting channel and closes the first connecting channel.

[0025] By adopting the above technical solution, when the blowpipe is facing the primary bubble mold, the switching bar opens the first connecting channel and closes the second connecting channel, forcing the first push plate to slide towards the side closer to the connecting cavity, thereby blowing the air in the first blowing chamber into the primary bubble mold through the blowpipe, causing the glass material to form a glass bubble. When the flipping shaft rotates and drives the blowpipe towards the forming mold, under the pull of the first rack, the switching bar opens the second connecting channel and closes the first connecting channel, forcing the second push plate to slide towards the side closer to the connecting cavity, thereby blowing the air in the second blowing chamber into the forming mold through the blowpipe, improving the ease of operation when switching between the first and second blowing chambers.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a rotating shaft, molten glass is dripped into the initial bubble mold during glass bottle production, forming a glass mass. Air is blown into the glass mass through a blowpipe, creating an internal air cavity to form a glass bubble. The initial bubble mold and the forming mold are then opened, driving the rotating shaft to rotate and causing the blowpipe to flip the glass bubble downwards. The forming mold is then closed, and air continues to be blown into the glass bubble through the blowpipe until the molten glass completely adheres to the inner wall of the forming mold, ultimately producing the glass bottle. The initial bubble mold and the forming mold share a blowpipe, and the rotation of the blowpipe facilitates the transfer of the glass bubble, greatly improving the ease of transfer, reducing overall space occupation, and minimizing the possibility of indentations during glass bubble transfer. 2. With the first and second push blocks, when the initial bubble mold or the forming mold is closed, the sliding bar pushes the push-pull bar through the first push block, thereby pulling back the second rack, and at this time there is a gap between the second push block and the push-pull bar. When the initial bubble mold or the forming mold is opened, it drives the two forming half molds away from each other. Only after the second push block slides to abut against the push-pull bar can the second rack be pushed. The effect is that the initial bubble mold and the forming mold can be opened first, and then the second rack can be pushed to drive the flipping shaft to rotate. This achieves the sequential opening of the initial bubble mold and the forming mold and the flipping of the flipping shaft, avoiding the possibility of interference between the glass bubble and the initial bubble mold or the forming mold during the mold opening process. 3. By configuring the air blowing seat, when the blowing tube is flipped to face the initial bubble mold, the first pushing member drives the first pushing plate to slide towards the side closer to the connecting cavity, thereby squeezing the air in the first blowing chamber into the connecting cavity and blowing it out through the blowing tube, causing the glass material in the initial bubble mold to form a glass bubble. After the glass bubble is transferred to the forming mold, the second pushing plate is driven to slide towards the side closer to the connecting cavity, thereby squeezing the air in the second blowing chamber into the connecting cavity and blowing it out through the blowing tube, causing the glass bubble to continue to expand and produce a glass bottle. By utilizing the size of the first and second blowing chambers, the amount of air blown into the initial bubble mold or forming mold can be controlled, achieving precise control of the air pressure.

[0029] The following combination Figures 1-8 This application will be described in further detail.

[0030] Example 1: This application discloses a glass bottle blowing molding process.

[0031] Reference Figure 1 A glass bottle blowing process includes the following steps: S1. Material Picking and Blanking: Molten glass raw material (in a viscous liquid state) at about 1500℃ is picked up manually or by a robotic arm and dripped into the primary bubble mold 1 to obtain a glass clump, which lays the foundation for subsequent blowing.

[0032] S2. Initial bubble formation: Using the blowpipe 41, air is slowly blown into the initial bubble mold 1 to form tiny air cavities inside the glass material, thus producing a glass bubble (similar to a small lantern, with a loose shape).

[0033] S3. Molding and Shaping: The glass bubble is transferred to the molding mold 2 through the blowpipe 41, and air is blown into the glass bubble through the blowpipe 41 until the molten glass material completely adheres to the inner wall of the molding mold 2, accurately replicating the shape of the molding mold 2 to produce a glass wine bottle.

[0034] S4. Demolding and Cooling: After the glass bottle has cooled to a hardened state (still at a certain temperature to avoid brittleness), open the molding mold 2 and take out the molded glass bottle. Then put it into the annealing furnace to cool down slowly (to eliminate internal stress and prevent subsequent breakage). After cooling, the final finished glass bottle is obtained.

[0035] Reference Figure 2 , Figure 3 In this embodiment, the glass bottle blowing process takes place on a workbench 3, where both the initial blowing mold 1 and the final forming mold 2 are mounted. To improve the production efficiency of the glass bottles, multiple initial blowing molds 1 and multiple final forming molds 2 are provided on the workbench 3, arranged at intervals along a horizontal direction. The multiple initial blowing molds 1 and multiple final forming molds 2 are correspondingly arranged, with each initial blowing mold 1 located above its corresponding final forming mold 2.

[0036] In this embodiment, the sidewalls of the workbench 3 are respectively equipped with a first slide rail 33 and a second slide rail 34. The initial foaming mold 1 includes two initial foaming half-molds 11. A first slider is fixedly installed on the back of each initial foaming half-mold 11. The first slider is slidably installed on the first slide rail 33. The initial foaming half-mold 11 is slidably installed on the first slide rail 33 of the workbench 3 via the first slider. The molding mold 2 includes two molding half-molds 21. A second slider is fixedly installed on the back of each molding half-mold 21. The second slider is slidably installed on the second slide rail 34. The molding half-mold 21 is slidably installed on the second slide rail 34 of the workbench 3 via the second slider.

[0037] Two initial foaming half molds 11 and two molding half molds 21 are set up accordingly. A connecting strip 12 is installed between each initial foaming half mold 11 and the corresponding molding half mold 21. The initial foaming half mold 11 is fixedly connected to the corresponding molding half mold 21 through the connecting strip 12.

[0038] In this embodiment, the molding die 2 is connected to two sliding bars 22. One sliding bar 22 is fixedly connected to the second slider of one of the molding half-die 21 in the molding die 2, and the other sliding bar 22 is fixedly connected to the second slider of the other molding half-die 21 in the molding die 2. Both sliding bars 22 extend horizontally to connect all the molding half-die 21s in the molding die 2. The effect is that when the two sliding bars 22 are controlled to slide along their own length direction, and the moving directions of the two sliding bars 22 are opposite, all the molding dies 2 can be controlled to open and close synchronously (i.e., to control the two molding half-die 21s in the molding die 2 to move closer or further apart).

[0039] The worktable 3 is equipped with an opening and closing mechanism, which is used to drive the two molding halves 21 in the molding mold 2 to move closer or further apart. In this embodiment, the opening and closing mechanism includes two driving cylinders 31, which are correspondingly arranged with two sliding bars 22. The cylinder body of each driving cylinder 31 is fixedly installed on the side wall of the worktable 3, and the piston rod of each driving cylinder 31 is fixedly connected to the corresponding sliding bar 22. With this design, when the piston rod of one driving cylinder 31 is driven to extend outward and the piston rod of the other driving cylinder 31 is driven to retract inward, the two molding halves 21 in the molding mold 2 can be driven to move closer or further apart, realizing the opening and closing of the molding mold 2 and the initial foaming mold 1.

[0040] Reference Figure 2 , Figure 3 A rotating shaft 4 is rotatably mounted on the side wall of the worktable 3. The rotating shaft 4 is located between the initial foaming mold 1 and the forming mold 2. A drive motor 35 is fixedly mounted on the side wall of the worktable 3. The output of the drive motor 35 is coaxially connected to the rotating shaft 4 to drive the rotating shaft 4 to rotate around its own central axis. Blowpipes 41 are fixedly connected to the rotating shaft 4. The number of blowpipes 41 corresponds to the number of forming molds 2 (initial foaming mold 1). The rotation of the rotating shaft 4 is used to control the insertion of the blowpipes 41 into the initial foaming mold 1 or the forming mold 2.

[0041] Reference Figure 3 , Figure 4In this embodiment, the workbench 3 is provided with a mounting ring 36, which can be fixedly installed on the side wall of the workbench 3 by means of a clamp (not shown in the figure). A tilting shaft 4 passes through the mounting ring 36, and a first cavity 42 is formed inside the tilting shaft 4. One end of the blowpipe 41 is connected to the first cavity 42. A second cavity 361 is formed between the mounting ring 36 and the outer peripheral wall of the tilting shaft 4. Multiple connecting holes 421 are formed on the outer wall of the tilting shaft 4, and these holes are arranged at intervals around the central axis of the tilting shaft 4. The first cavity 42 and the second cavity 361 are interconnected through these connecting holes 421. An air supply pipe 362 is connected to the mounting ring 36. One end of the air supply pipe 362 is connected to the second cavity 361, and the other end is used to connect to an air supply device (such as an air compressor).

[0042] Reference Figure 2 , Figure 3 A first rotating rod 37 and a second rotating rod 38 are rotatably mounted on the worktable 3. The first rotating rod 37 is located at the top of the primary foaming mold 1, and a first sealing head 371 is fixedly mounted on the first rotating rod 37. The first sealing head 371 is used to seal the upper opening of the primary foaming mold 1 (the lower opening of the primary foaming mold 1 is used for the insertion of the blowpipe 41). The second rotating rod 38 is located at the bottom of the forming mold 2, and a second sealing head 381 is fixedly mounted on the second rotating rod 38. The second sealing head 381 is used to seal the lower opening of the forming mold 2 (the upper opening of the forming mold 2 is used for the insertion of the blowpipe 41). In this embodiment, both the first rotating rod 37 and the second rotating rod 38 are driven by cylinders.

[0043] It should be noted that, in this embodiment, after the glass bottle is formed in the molding mold 2, the formed glass bottle can be transferred to the annealing furnace for cooling using clamping equipment such as bottle mouth pliers (not shown in the figure).

[0044] The implementation principle of Embodiment 1 of this application is as follows: by setting multiple initial foaming molds 1 and forming molds 2, the production efficiency of glass wine bottles is improved. During production, the blowpipe 41 is rotated to face upward, driving the two initial foaming half molds 11 in the initial foaming mold 1 to fit together, so that the blowpipe 41 extends into the initial foaming mold 1.

[0045] Next, molten glass is dripped into the initial bubble mold 1, causing the first rotating rod 37 to rotate and forcing the first sealing head 371 to cover the upper opening of the initial bubble mold 1. Air is then blown into the blowpipe 41, creating an air cavity inside the glass mass, thus forming a glass bubble. The initial bubble mold 1 and the forming mold 2 are then opened, causing the flipping shaft 4 to rotate 180°, causing the blowpipe 41 to flip the glass bubble downwards. The forming mold 2 is then closed, and the second sealing head 381 covers the lower opening of the forming mold 2. Air continues to be blown into the glass bubble through the blowpipe 41 until the molten glass completely adheres to the inner wall of the forming mold 2, ultimately producing a glass bottle.

[0046] The initial bubble mold 1 and the forming mold 2 share the same blowpipe 41, and the glass bubble is transferred by flipping the blowpipe 41, which greatly improves the convenience of glass bubble transfer, reduces the overall space occupation, and reduces the possibility of indentation on the surface during glass bubble transfer.

[0047] Example 2: This application discloses a glass bottle blowing molding process.

[0048] The difference between the glass bottle blowing process disclosed in this application and Example 1 is that: Reference Figure 5 , Figure 6 In this embodiment, no drive motor 35 is provided. The side wall of the worktable 3 is rotatably mounted with a linkage shaft 5. One end of the outer peripheral wall of the flip shaft 4 is coaxially fixed with a first bevel gear 43. The outer peripheral wall of the linkage shaft 5 is coaxially fixed with a second bevel gear 52. The first bevel gear 43 and the second bevel gear 52 mesh and drive each other so that the linkage shaft 5 and the flip shaft 4 are circumferentially linked (that is, when the linkage shaft 5 rotates, it drives the flip shaft 4 to rotate synchronously).

[0049] A first gear 51 is coaxially fixed to the outer peripheral wall of one end of the linkage shaft 5. A first rack 32 is slidably mounted on the worktable 3. The sliding direction of the first rack 32 is the same as the sliding direction of the sliding bar 22. The first gear 51 and the first rack 32 mesh and drive each other. A first translation groove for the first rack 32 to slide is opened on the side wall of the worktable 3.

[0050] The worktable 3 is equipped with a drive assembly 6 that drives the first rack 32 to reciprocate. The drive assembly 6 includes a drive shaft 61, a drive frame 62, and a drive component. The drive shaft 61 is rotatably mounted on the worktable 3. A connecting arm 612 is fixedly mounted on the outer peripheral wall of the drive shaft 61. A drive column 611 is mounted on the end of the connecting arm 612 away from the drive shaft 61. The drive column 611 is eccentrically positioned with respect to the drive shaft 61 via the connecting arm 612 (i.e., when the drive shaft 61 rotates, it drives the drive column 611 to "revolve" around the central axis of the drive shaft 61). The drive frame 62 is fixedly mounted on the first rack 32 and has a drive groove 621 for the drive column 611 to be inserted. When the drive shaft 61 rotates, the drive shaft 61 drives the drive frame 62 to reciprocate via the drive column 611.

[0051] A driving component is mounted on the worktable 3 to drive the drive shaft 61 to rotate. The driving component includes a second gear 63 and a second rack 64. The second gear 63 is coaxially mounted on the outer peripheral wall of the drive shaft 61. One end of the second rack 64 is connected to the sliding bar 22. The second rack 64 is slidably mounted on the side wall of the worktable 3. The side wall of the worktable 3 is provided with a second translation groove for the second rack 64 to slide. The sliding direction of the second rack 64 is the same as the sliding direction of the first rack 32. The second gear 63 and the second rack 64 mesh and transmit power.

[0052] A push-pull strip 65 is fixedly connected to one end of the second rack 64. The push-pull strip 65 has a through groove 651 for the sliding strip 22 to pass through. A first push block 221 and a second push block 222 are fixedly installed on the sliding strip 22. The first push block 221 and the second push block 222 are arranged at intervals along the length of the sliding strip 22. The first push block 221 is located on the side of the second push block 222 away from the driving cylinder 31 (the driving cylinder 31 is not shown in the figure of this embodiment). The distance between the first push block 221 and the second push block 222 is greater than the thickness of the push-pull strip 65. When the molding mold 2 opens, the sliding strip 22 pushes the push-pull strip 65 through the second push block 222. When the molding mold 2 closes, the sliding strip 22 pushes the push-pull strip 65 through the first push block 221.

[0053] Reference Figure 6 , Figure 7 A rotating sleeve 631 is fixedly mounted on the inner circumferential wall of the second gear 63. The rotating sleeve 631 is rotatably mounted on the outer circumferential wall of the drive shaft 61, and the second gear 63 is rotatably mounted on the drive shaft 61 via the rotating sleeve 631. A one-way rotating member 7 is provided between the rotating sleeve 631 and the drive shaft 61. When the two molding half molds 21 move away from each other, the one-way rotating member 7 forces the rotating sleeve 631 and the drive shaft 61 to move circumferentially (i.e., the rotating sleeve 631 can drive the drive shaft 61 to rotate). When the two molding half molds 21 approach each other, the rotating sleeve 631 and the drive shaft 61 are disengaged (i.e., the rotating sleeve 631 cannot drive the drive shaft 61 to rotate).

[0054] The inner circumferential wall of the rotating sleeve 631 has a limiting groove 632, the limiting groove 632 has a limiting arc surface 633, the limiting arc surface 633 has a first limiting side 634 and a second limiting side 635, the distance from the first limiting side 634 to the center of the drive shaft 61 is less than the distance from the second limiting side 635 to the center of the drive shaft 61. The unidirectional rotating component 7 includes a limiting post 71 and a limiting spring 72. The limiting post 71 is installed in the limiting groove 632, one end of the limiting spring 72 is fixedly connected to the inner wall of the limiting groove 632, and the other end is fixedly connected to the limiting post 71. Under normal conditions, the limiting spring 72 forces the limiting post 71 to move toward the first limiting side 634, and at the same time abuts against the limiting arc surface 633 and the outer circumferential wall of the drive shaft 61.

[0055] The implementation principle of Embodiment 2 of this application is as follows: After the glass bubble is formed in the initial bubble mold 1, the sliding bar 22 is driven to slide, causing the two forming half molds 21 to move away from each other, thereby opening the initial bubble mold 1 and the forming mold 2. During this process, the sliding bar 22 pushes the push-pull bar 65 of the second rack 64 through the second push block 222, thereby driving the second gear 63 to rotate, driving the drive shaft 61 to rotate. The drive shaft 61 pushes the drive frame 62 of the first rack 32 through the drive column 611, thereby driving the linkage shaft 5 to rotate through the first gear 51, that is, forcing the flip shaft 4 to rotate, thereby transferring the glass bubble in the initial bubble mold 1 to the forming mold 2.

[0056] After the glass bubble is transferred to the molding mold 2, the sliding bar 22 is driven to slide in the opposite direction, causing the two molding half molds 21 to fit together. The sliding bar 22 drives the second rack 64 to reset through the first push block 221. During this process, the second gear 63 cannot drive the drive shaft 61 to rotate. That is, the flip shaft 4 remains stationary during this process, so that the blowpipe 41 remains facing the molding mold 2. When the two molding half molds 21 fit together, the blowpipe 41 is inserted into the molding mold 2 to facilitate further blowing of the glass bubble.

[0057] After the glass bubble is blown into a glass bottle, the sliding bar 22 is moved to move the two forming half-molds 21 away from each other, allowing the initial bubble mold 1 and the forming mold 2 to be opened again, thus removing the formed glass bottle. After the glass bottle is removed, the two forming half-molds 21 are moved away from each other again. At this time, the sliding bar 22 pushes the push-pull bar 65 of the second rack 64 through the second push block 222, thereby forcing the flip shaft 4 to rotate again and rotating the blowpipe 41 to face the initial bubble mold 1. This process is repeated to continuously produce glass bottles, greatly improving the ease of operation of the overall structure.

[0058] Example 3: This application discloses a glass bottle blowing molding process.

[0059] The difference between the glass bottle blowing process disclosed in this application and Example 2 is as follows: Reference Figure 8 In this embodiment, an air-blowing seat 8 is installed on the workbench 3. The air-blowing seat 8 has a first air-blowing chamber 81, a second air-blowing chamber 82, and a connecting chamber 83. The end of the air supply pipe 362 away from the mounting ring 36 is connected to the connecting chamber 83 (i.e., the air pipe 41 and the connecting chamber 83 are interconnected). The inner wall of the connecting chamber 83 has a first connecting channel 812 and a second connecting channel 822. The first connecting channel 812 connects to the first air-blowing chamber 81, and the second connecting channel 822 connects to the second air-blowing chamber 82. A first push plate 811 is slidably installed in the first air-blowing chamber 81, and a second push plate 821 is slidably installed in the second air-blowing chamber 82. The air-blowing seat 8 is provided with a first pushing member and a second pushing member.

[0060] The first pushing component is configured as a first cylinder 85, the cylinder body of which is mounted on the side wall of the air blowing seat 8, and the piston rod of which passes through the first air blowing chamber 81 and is fixedly connected to the first push plate 811. The second pushing component is configured as a second cylinder 86, the cylinder body of which is mounted on the side wall of the air blowing seat 8, and the piston rod of which passes through the second air blowing chamber 82 and is fixedly connected to the second push plate 821.

[0061] A switching strip 84 is slidably installed within the connecting cavity 83. The switching strip 84 has a switching hole 841. One end of the switching strip 84 extends out of the air-blowing seat 8 and is fixedly connected to the first rack 32 (not shown in this embodiment). When the blow pipe 41 faces the initial foaming mold 1, the switching strip 84 closes the second connecting channel 822, and the switching hole 841 of the switching strip 84 connects to the first connecting channel 812, that is, the switching strip 84 opens the first connecting channel 812 and closes the second connecting channel 822. When the blow pipe 41 faces the molding mold 2, the switching strip 84 closes the first connecting channel 812, and the switching hole 841 of the switching strip 84 connects to the second connecting channel 822, that is, the switching strip 84 opens the second connecting channel 822 and closes the first connecting channel 812.

[0062] The implementation principle of Embodiment 3 of this application is as follows: When the blowpipe 41 is facing the primary bubble mold 1, the switching bar 84 opens the first connecting channel 812 and closes the second connecting channel 822, forcing the first push plate 811 to slide towards the side close to the connecting cavity 83, thereby blowing the air in the first blowing cavity 81 into the primary bubble mold 1 through the blowpipe 41, so that the glass material clump forms a glass bubble.

[0063] When the rotating shaft 4 rotates and drives the blowpipe 41 toward the forming mold 2, under the pull of the first rack 32, the switching bar 84 opens the second connecting channel 822 and closes the first connecting channel 812, forcing the second push plate 821 to slide toward the side closer to the connecting cavity 83, thereby blowing the air in the second blowing cavity 82 into the forming mold 2 through the blowpipe 41, so that the glass bubble forms a glass wine bottle.

[0064] The switching bar 84 is driven by the first rack 32, improving the ease of switching between the first blowing chamber 81 and the second blowing chamber 82. Utilizing the spatial dimensions of the first blowing chamber 81 and the second blowing chamber 82, and through the known sliding amount of the first push plate 811 and the second push plate 821, the amount of air blown into the initial foaming mold 1 or the forming mold 2 is controlled, achieving precise air pressure control and thus improving the blowing quality of the glass bottle.

[0065] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
