Abstract
Description
Technical Field
[0001] This invention relates to the field of vial making machine technology, specifically to a vial neck forming and stabilizing device. Background Technology
[0002] In the vial production process, vial neck forming is a crucial step that directly determines product quality. Its forming precision, appearance quality, and structural stability directly affect the vial's sealing performance, safety, and market acceptance. Currently, most mainstream vial neck forming solutions in the industry adopt a driven wheel forming structure. In this structure, during the extrusion forming process, the friction force of the vial's rotation drives the die wheel to passively follow the rotation, completing the neck forming process through die wheel extrusion.
[0003] However, existing driven wheel molding solutions have significant quality shortcomings in practical applications, most notably the presence of color spots and wrinkles at the bottle neck, severely restricting product yield. The core cause of color spot defects is the multiple contamination risks arising from the dynamic contact of the driven wheel: First, the rotational speed of the mold wheel is prone to deviate from that of the bottle body, causing irregular friction between them. This leads to abrasive debris and metal powder adhering to the mold wheel surface falling off and embedding into the molten glass at the bottle neck. Second, the frequent contact of the mold wheel with different bottles makes it difficult to completely remove glass residue from previous processing, which is transferred to the new bottle neck and fused with the molten glass during rotation. Third, the dynamic rotation of the mold wheel drives the surrounding airflow, accelerating the adsorption of dust, fibers, and other pollutants from the environment onto the mold wheel surface or the molten bottle neck.
[0004] Among them, wrinkle defects are caused by the lag in the rotation of the driven wheel and the unstable force, which leads to uncontrolled glass flow: On the one hand, the rotation mode of the mold wheel, which is driven by the bottle, inevitably has a speed difference between the bottle speed and the lagging mold wheel. The lagging mold wheel obstructs the molten glass, causing the molten glass to accumulate locally and be forcibly squeezed to form layered wrinkles; on the other hand, factors such as bushing wear and bottle positioning deviation will cause frequent fluctuations in the contact angle and extrusion pressure between the mold wheel and the bottle mouth, and the molten glass is prone to stretching or folding under unstable external forces; in addition, the dynamic contact of the driven wheel cannot stably control the glass flow speed, resulting in disordered molten glass filling and forming rhythm, and the difference in flow speed in different areas further aggravates the formation of wrinkles.
[0005] The aforementioned defects such as color spots and wrinkles not only disrupt the uniformity of the appearance of vials, but more seriously, they affect the integrity of the bottle mouth seal and the purity of the contents, posing safety hazards to applications in the pharmaceutical, food and other fields, while also increasing rework costs for enterprises. Summary of the Invention
[0006] To overcome the above-mentioned defects, embodiments of the present invention provide a vial mouth forming stabilizing device, which solves the technical problem in the prior art that when the die wheel that follows the rotation of the bottle body is extruding the mouth during the mouth forming extrusion, color spots and wrinkles are easily caused at the mouth.
[0007] According to one aspect, at least one embodiment of the present invention provides a vial neck forming stabilizing device, comprising:

[0018] A wiping block, mounted on the bracket, is capable of wiping the peripheral wall of the mold wheel when the rotary drive assembly drives the mold wheel to rotate.
[0019] Optionally, the rotary drive assembly includes:
[0020] A ratchet is coaxially mounted on the mold wheel;
[0021] One end of the lever is rotatably connected to the axle of the ratchet, and the other end is hinged to the bracket with a pusher.
[0022] A push pawl is hinged to the swing arm and engages with the ratchet, used to drive the ratchet to rotate under the swing action of the swing arm;
[0023] A limiting pawl is hinged to the bracket and spaced apart from the pushing pawl, used to limit the ratchet from rotating in the opposite direction;
[0024] A torsion spring is provided between the limiting pawl and the bracket, and between the pushing pawl and the rocker arm. The torsion spring acts on the limiting pawl and the pushing pawl to keep the limiting pawl or the pushing pawl engaged with the ratchet.
[0025] Optionally, the slide is provided with an installation cylinder, the axle of the mold wheel is rotatably mounted on the installation cylinder, and an oil nozzle facing the core column is provided on the outer wall of the installation cylinder. When the core column is separated from the bottle, the oil nozzle is used to inject lubricating oil onto the outer peripheral wall of the core column.
[0026] Optionally, the lifting seat is provided with a collection groove, the bottom of the collection groove is provided with an oil drain port, and a downwardly inclined guide plate is provided in the collection groove. The guide plate is used to guide the lubricating oil in the collection groove to the oil drain port, and the core column is provided on the guide plate.
[0027] Optionally, the worktable is further provided with several heating components for heating the bottle mouth of the bottle to be formed. Each heating component corresponds to one of the mold components. The heating components include:
[0028] A lifting and adjusting seat is provided on the worktable;
[0029] The clamp is disposed on the movable end of the lifting adjustment seat;
[0030] A flame heating gun is mounted on the fixture and is used to heat the mouth of the bottle to be formed.
[0031] Optionally, the clamping drive mechanism includes:

[0033] Optionally, the clamping assembly includes:

[0037] A lifting actuating component is disposed on the turntable. The lifting actuating component is rotatably engaged with the key shaft to drive the key shaft to move up and down.
[0038] Optionally, the lifting actuating element includes:
[0039] The mounting plate is detachably mounted on the turntable.
[0040] The lifting device is mounted on the mounting plate and located outside the turntable;
[0041] A shift fork is disposed on the movable end of the lifting device. A connecting ring is rotatably disposed inside the shift fork. The connecting ring is fixedly sleeved on the key shaft and can rotate relative to the shift fork when the key shaft rotates.
[0042] The beneficial effects of this invention are as follows:
[0043] In this invention, the clamping and driving mechanism drives the bottle to be formed to rotate and move it above the core column. The core column is then inserted upwards and internally supported within the bottle opening. Simultaneously, two mold wheels move in a direction that approaches each other, extruding and forming the outer wall of the bottle opening. During this process, the mold wheels remain fixed and do not rotate; the extrusion forming of the bottle opening is completed solely by the rotation of the bottle to be formed. The fixed mold wheels eliminate dynamic friction contamination and avoid irregular friction caused by speed differences. The amount of debris and metal powder generated by wear on the mold wheel surface is significantly reduced and will not embed in the molten glass. Furthermore, the fixed mold wheels provide more thorough cleaning without secondary contamination, and the cleaning range is clearly defined. Surface residue can be specifically removed before use, preventing the transfer of contaminants due to rotation. The absence of airflow caused by dynamic rotation reduces the adsorption of environmental impurities and significantly lowers the probability of color spots. Regarding wrinkles, the absence of speed differences prevents glass accumulation, allowing the molten glass to flow smoothly along the contour of the fixed mold wheels. The contact angle and extrusion pressure between the mold wheels and the bottle opening are constant, ensuring stable force and controllable shape. Attached Figure Description

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.
[0057] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0058] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

They are used only for the convenience of description and simplification of operation, and are not intended to 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 present invention.
[0061] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0062] like Figures 1-3 As shown, an embodiment of the present invention illustrates a vial neck forming stabilizing device, including a worktable 1, a clamping drive mechanism 2, and several sets of mold assemblies 3. The clamping drive mechanism 2 is disposed on the worktable 1 and has several clamping components for clamping and driving the vial body 100 to be formed to rotate. The clamping drive mechanism 2 can drive the clamping components and the vial body 100 to be formed to revolve synchronously. Several sets of mold assemblies 3 are arranged circumferentially on the worktable 1. Each set of mold assemblies 3 has two spaced mold wheels 31 that can move in a direction that approaches or moves away from each other, and a core column 32 located between the two mold wheels 31. The moving direction of the mold wheels 31 is radial. It should be noted that during the extrusion molding of the vial neck, the clamping assembly clamps the bottom of the vial body, which allows the vial body to be in an inverted state with the neck facing downwards. With the clamping assembly's belt pointing downwards, the vial body rotates. When the clamping drive mechanism 2 moves the vial body 100 to be molded above the core column 32, the core column 32 can be inserted upwards and internally supported within the neck of the vial body 100. The two mold wheels 31 move in a direction that approaches each other to extrude and mold the outer wall of the neck. Most importantly, this device differs from traditional devices in that the mold wheels 31 do not rotate during the process of contacting and extruding the neck.
[0063] In the above scheme, during operation, the clamping drive mechanism 2 drives the bottle body 100 to be formed to rotate and move it above the core column 32. The core column 32 is then inserted upwards and internally supported within the bottle mouth of the bottle body 100. It can be understood that, according to the required forming shape of the inner wall of the bottle mouth and neck, a corresponding forming groove is formed on the outer peripheral wall of the core column 32. At the same time, the two die wheels 31 move in a direction that approaches each other, extruding and forming the outer wall of the bottle mouth. During this process, the die wheels 31 remain fixed and do not rotate, and the extrusion forming of the bottle mouth is completed solely by the rotation of the bottle body 100 to be formed.
[0064] Specifically, in the original driven wheel mode, the mold wheel 31 rotates along with the glass bottle, resulting in more color spots and wrinkles. The main reason is the risk of contamination from the dynamic contact of the mold wheel 31 in the driven wheel mode and the uncontrolled glass flow caused by the rotational lag. In this embodiment, the mold wheel 31 is fixed and does not rotate, eliminating dynamic friction contamination and avoiding irregular friction caused by the speed difference. The debris and metal powder generated by the wear of the mold wheel surface are greatly reduced and will not be embedded in the molten glass. At the same time, the fixed mold wheel 31 is cleaner and has no secondary contamination. The cleaning range is clear, and surface residues can be targeted to be removed before use. It will not transfer contaminants due to rotation, and there is no air flow driven by dynamic rotation, which reduces the adsorption of environmental impurities and greatly reduces the probability of color spots. In terms of wrinkles, the absence of speed difference avoids glass accumulation. The molten glass can flow smoothly along the contour of the fixed mold wheel, and the contact angle and extrusion pressure between the mold wheel 31 and the bottle mouth are constant. The stable force makes the shape controllable, and the glass heating temperature and processing rhythm can be precisely adjusted to ensure matching flow rhythm and effectively reduce the generation of wrinkles.
[0065] like Figures 4-7 As shown, the mold assembly 3 further includes a mounting base 33, a bidirectional lead screw motor 35, lead screw nuts 36, and a lifting seat 37. The mounting base 33 is mounted on the worktable 1, and two slide blocks 34 are slidably mounted on the mounting base 33. Each slide block 34 corresponds to a mold wheel 31. The bidirectional lead screw motor 35 is mounted inside the mounting base 33. The lead screw of the bidirectional lead screw motor 35 has two threaded sections with opposite directions of rotation. Two lead screw nuts 36 are threadedly connected to the threaded sections. The lead screw nuts 36 are fixedly connected to the slide blocks 34 and correspond to each other. The lifting seat 37 is mounted on the mounting base 33 and located between the two slide blocks 34. The core column 32 is located in the middle of the top surface of the lifting seat 37. It should be noted that the lifting seat 37 does not affect the movement of the two slide blocks 34. That is, when the two slide blocks 34 move close to each other to their maximum distance, the two slide blocks 34 are just in contact with the lifting seat 37 or still not in contact with the lifting seat 37.
[0066] In the above scheme, when the clamping drive mechanism 2 moves the bottle body 100 to be formed above the core column 32, the lifting seat 37 moves the core column 32 upward to insert and support it inside the bottle mouth. Then, the bidirectional lead screw motor 35 starts and drives the two lead screw nuts 36 to move in opposite directions. The lead screw nuts 36 drive the corresponding slides 34 to move closer to each other. The mold wheel 31 on the slide 34 then moves closer to the bottle mouth and extrudes and forms its outer wall. After the forming is completed, the bidirectional lead screw motor 35 rotates in the opposite direction to move the slide 34 and the mold wheel 31 away from each other. The lifting seat 37 moves the core column 32 downward to disengage from the bottle mouth.
[0067] In this embodiment, the bidirectional lead screw motor 35 drives the slide 34 to move, which can precisely control the approach distance and squeezing force of the two mold wheels 31, ensuring a stable contact state between the mold wheels 31 and the bottle mouth, and avoiding wrinkles caused by unstable force. The lifting seat 37 drives the core column 32 to rise and fall, making the inner support position of the core column 32 more accurate, further ensuring the forming accuracy of the bottle mouth. At the same time, in conjunction with the fixed structure of the mold wheels 31, the color spots and wrinkles are reduced from both dynamic contact control and structural positioning aspects, thereby improving the product qualification rate.
[0068] like Figures 4-5 As shown, the slide 34 is further provided with a mold wheel intermittent rotation control assembly 4, which includes a bracket 2, a rotation drive assembly, and a wiping block 46. The rotation drive assembly includes a ratchet 41, a pusher 43, a fixed plate 44, a limiting pawl 45, a swing arm 47, and a pusher pawl 48. It should be noted that the mold wheel intermittent rotation control assembly 4 can be used to drive the mold wheel to rotate intermittently, so that the mold wheel contacts the bottle at different circumferential positions each time, reducing the impact of the mold wheel's heat on the bottle. The wiping block 46 can be a sponge block or a wiping cloth stacked into a block structure, and the wiping block 46 can be detachably connected to the fixed plate 44. In addition, the pusher 43 is a small electric push rod. Specifically, a ratchet 41 is mounted on the mold wheel 31 to drive the mold wheel 31 to rotate. A bracket 42 is mounted on the slide block 34, and a pusher 43 is mounted on the bracket 42. A fixed plate 44 is mounted on the bracket 42, and a limiting pawl 45 is mounted on the fixed plate 44. The limiting pawl 45 meshes with the ratchet 41. A wiping block 46 is provided on the bottom surface of the fixed plate 44, and the wiping block 46 abuts against the outer peripheral wall of the mold wheel 31. One end of the rocker arm 47 is rotatably connected to the axle of the ratchet 41, and the other end is hinged to the pushing end of the pusher 43. A pushing pawl 48 is provided on the rocker arm 47.
[0069] In the above scheme, when the mold wheel 31 needs to be moved and adjusted, the pusher 43 starts and extends, driving the swing arm 47 to swing. The swing arm 47 drives the pusher pawl 48 to push the ratchet 41 to rotate. The ratchet 41 drives the mold wheel 31 to rotate synchronously. At the same time, the wiping block 46, which abuts against the outer peripheral wall of the mold wheel 31, wipes the peripheral wall of the rotating mold wheel 31. The limiting pawl 45 is always engaged with the ratchet 41 during the rotation of the ratchet 41. When the pusher 43 shortens and retracts, the swing arm 47 drives the pusher pawl 48 to reset. At this time, the ratchet 41 does not reverse under the limiting action of the limiting pawl 45, ensuring the stability of the mold wheel 31. When the mold wheel 31 moves to the processing position for extrusion molding, the pusher 43 stops working. Under the limiting action of the pusher pawl 48 and the limiting pawl 45, the mold wheel 31 remains fixed and does not rotate.
[0070] In the driven wheel mode, the mold wheel 31 needs to frequently come into contact with different glass, and the residue from the previous processing is difficult to clean thoroughly. During rotation, contaminants are easily transferred, resulting in color spots. In this embodiment, the mold wheel intermittent rotation control component 4 realizes the rotation and wiping of the mold wheel 31 during movement. The wiping block 46 can completely remove abrasive debris, metal powder and previous processing residue from the surface of the mold wheel 31. The limiting pawl 45 ensures that the mold wheel 31 rotates stably in one direction during wiping, making the wiping more thorough. The mold wheel 31 is fixed and does not rotate during processing to avoid the re-adsorption of impurities after wiping. Combined with the anti-pollution advantage of the fixed mold wheel 31 itself, the path of color spot generation is further blocked from the cleaning perspective. At the same time, the structure of the mold wheel intermittent rotation control component 4 does not affect the fixed state of the mold wheel 31 during processing, ensuring molding stability.
[0071] Furthermore, torsion springs are installed on the axles of both the pushing pawl 48 and the limiting pawl 45. The torsion springs are used to drive the pushing pawl 48 and the limiting pawl 45 to press against the outer peripheral wall of the ratchet 41. Since the ratchet 41, the pushing pawl 48, and the limiting pawl 45 are all horizontally arranged, it is impossible to achieve a tight contact with the ratchet 41 by the weight of the pawls themselves. By adding torsion springs, it can be ensured that the pushing pawl 48 and the limiting pawl 45 are always in close contact with the ratchet 41.
[0072] In the above scheme, when the pusher 43 drives the rocker arm 47 to swing, the torsion spring on the pusher pawl 48 always applies pressure to keep the pusher pawl 48 tightly against the tooth surface of the ratchet 41, ensuring that the pusher pawl 48 can effectively drive the ratchet 41 to rotate. The torsion spring on the limit pawl 45 also applies pressure to keep the limit pawl 45 tightly engaged with the tooth surface of the ratchet 41, preventing the ratchet 41 from rotating in the non-pushing direction. During the wiping process of the mold wheel 31, the pressure of the torsion spring keeps the engagement between the pawl and the ratchet 41 stable. Even if the ratchet 41 vibrates slightly, it will not cause the engagement to disengage. After wiping is completed, the pusher 43 resets, and the torsion spring drives the pusher pawl 48 and the limit pawl 45 to maintain the engagement with the ratchet 41.
[0073] The torsion spring ensures that the pawl and ratchet 41 are always pressed tightly together, preventing slippage and allowing the mold wheel 31 to rotate more smoothly and intermittently. The wiping block 46 can evenly wipe the perimeter of the mold wheel 31 and thoroughly remove surface impurities.
[0074] like Figures 6-7 As shown, furthermore, a mounting cylinder 5 is provided on the slide 34, and the axle of the mold wheel 31 is rotatably mounted on the mounting cylinder 5. An oil nozzle 6 facing the core column 32 is provided on the outer wall of the mounting cylinder 5. Specifically, an oil passage can be formed in the inner wall of the mounting cylinder 5, communicating with the oil nozzle 6, and the oil passage is also connected to an oil reservoir via a hose. Alternatively, it can be directly connected to the oil nozzle 6 via a hose, with the hose positioned on the outside of the mounting cylinder 5 and directly connected to the oil nozzle 6.
[0075] In the above scheme, after the bottle neck is formed, the lifting seat 37 moves the core column 32 downwards to detach from the bottle neck. At this time, the oil nozzle 6 on the mounting cylinder 5 is activated, injecting lubricating oil into the outer peripheral wall of the core column 32. The lubricating oil evenly covers the surface of the core column 32. After lubrication is completed, the oil nozzle 6 stops working, waiting for the next use of the core column 32. By injecting lubricating oil in a timely manner through the oil nozzle 6 after the core column 32 detaches from the bottle and during its downward movement, the friction and wear between the core column 32 and the inner wall of the bottle neck are reduced.
[0076] like Figure 8 As shown, the lifting seat 37 is further provided with a collection tank 7, the bottom of the collection tank 7 is provided with an oil drain port, and a guide plate 8 is provided inside the collection tank 7. The guide plate 8 is used to guide the lubricating oil in the collection tank 7 to the oil drain port. The core column 32 is provided on the guide plate 8, and the core column 32 can move up and down synchronously with the collection tank 7.
[0077] In the above scheme, when the nozzle 6 injects lubricating oil into the core column 32, excess lubricating oil drips into the collection tank 7 below. The guide plate 8 in the collection tank 7 guides the dripping lubricating oil to the bottom drain port. The lubricating oil is discharged from the collection tank 7 through the drain port for recycling or treatment. The core column 32 moves up and down synchronously with the collection tank 7 on the guide plate 8, without affecting its internal support and shaping function for the bottle mouth. If the lubricating oil injected by the nozzle 6 drips onto the worktable 1 or near the molten glass, it can easily cause pollution or equipment failure. However, the collection tank 7 and guide plate 8 in this embodiment can collect excess lubricating oil in time and treat it centrally through the drain port, avoiding lubricating oil pollution of the worktable 1 environment or dripping onto the molten glass to produce color spots. At the same time, the recycled lubricating oil can be reused after treatment, reducing lubricating oil consumption costs, keeping the working environment of the device clean, and reducing bottle mouth defects caused by environmental impurities.
[0078] like Figure 1 and Figure 10 As shown, furthermore, the workbench 1 is also provided with several heating components 9 for heating the bottle mouth of the bottle body 100 to be formed. The heating components 9 correspond one-to-one with the mold components 3. The heating components 9 are set on one side of the mold components 3. The heating components 9 include a lifting adjustment seat 91, a clamp 92 and a flame heating gun 93. The lifting adjustment seat 91 is set on the workbench 1, the clamp 92 is set on the movable end of the lifting adjustment seat 91, and the flame heating gun 93 is set on the clamp 92 for heating the bottle mouth of the bottle body 100 to be formed.
[0079] In the above scheme, the clamping drive mechanism 2 moves the bottle body 100 to be formed to one side of the heating component 9. The lifting adjustment seat 91 adjusts the height of the movable end, driving the clamp 92 and the flame heating gun 93 to rise and fall to a suitable position. The flame heating gun 93 is activated to heat the bottle mouth of the bottle body 100 to melt the glass at the bottle mouth. After heating, the clamping drive mechanism 2 moves the bottle body to the corresponding mold component 3 for extrusion forming. The flame heating gun 93 is turned off, and the lifting adjustment seat 91 drives it to reset. The heating component 9 and the mold component 3 correspond one-to-one. The position of the flame heating gun 93 can be precisely adjusted by the lifting adjustment seat 91. The bottle mouth heating temperature can be precisely controlled according to the contact state of the fixed mold wheel 31, thereby controlling the viscosity of the molten glass. This ensures that the glass flow speed is completely matched with the forming requirements of the mold wheel 31, avoiding wrinkles caused by chaotic flow rhythm. At the same time, precise heating reduces the situation of excessive or insufficient melting of glass, improves the forming accuracy of the bottle mouth, and further reduces defects with the stable extrusion of the fixed mold wheel 31.
[0080] like Figure 1 As shown, the clamping drive mechanism 2 further includes a turntable 10, which is disposed on the worktable 1. The clamping components correspond one-to-one with the mold components 3. Several clamping components are arranged circumferentially on the turntable 10, and the turntable 10 can drive the clamping components to revolve.
[0081] In the above scheme, several bottles 100 to be formed are clamped by corresponding clamping components. The turntable 10 starts to rotate, driving the clamping components and bottles to revolve together. When the bottle revolves to the corresponding mold component 3, the turntable 10 stops rotating, and the mold component 3 extrudes and forms the bottle mouth. After forming, the turntable 10 continues to rotate, transferring the formed bottle to the next process. At the same time, the unformed bottles are moved to the mold component 3 for processing. By driving multiple clamping components to revolve through the turntable 10, multi-station continuous processing is achieved, which greatly improves production efficiency. Moreover, the clamping components and mold components 3 correspond one-to-one, and each bottle can be formed in a fixed processing position, avoiding positioning deviations during the transfer process, ensuring that the processing conditions of each bottle are consistent, and improving product consistency. At the same time, the stable rotation of the turntable 10 makes the processing rhythm controllable. Combined with the stable forming of the fixed mold wheel 31, the quality of the bottle mouth is further guaranteed, and the generation of defective products is reduced.
[0082] like Figure 1As shown, the clamping drive mechanism 2 further includes a driver 21, a sleeve 22, a key shaft 23, a clamping head 24, and a lifting actuating member 25. The driver 21 is mounted on the turntable 10. The output end of the driver 21 passes through the turntable 10 and is provided with a sleeve 22. The sleeve 22 has a keyway. The key shaft 23 is slidably mounted in the sleeve 22. The clamping head 24 is located at the end of the key shaft 23 for clamping the bottle body 100 to be formed. The lifting actuating member 25 is mounted on the turntable 10. The lifting actuating member 25 has a actuating end, which is connected to the key shaft 23 for driving the key shaft 23 to slide up and down along the keyway to adjust the height of the clamping head 24 and the bottle body 100 to be formed.
[0083] In the above scheme, the bottle body 100 to be formed is clamped and fixed by the clamping head 24. The driver 21 is started to drive the sleeve 22 to rotate. The sleeve 22 drives the key shaft 23 and the clamping head 24 to rotate through the keyway, which in turn drives the bottle body to rotate. When it is necessary to adjust the height of the bottle body to match the core column 32 and the mold wheel 31, the actuating end of the lifting actuating component 25 drives the key shaft 23 to slide up and down along the keyway of the sleeve 22. The key shaft 23 drives the clamping head 24 and the bottle body to rise and fall synchronously. After adjusting to a suitable height, the lifting and falling stops. The bottle body is squeezed and formed by the mold wheel 31 while rotating.
[0084] In this embodiment, the drive 21 drives the sleeve 22 and key shaft 23 to achieve stable rotation of the bottle. The key shaft 23 and the keyway of the sleeve 22 cooperate to ensure stable power transmission during rotation and avoid fluctuations in the rotation speed of the bottle. The lifting and actuating component 25 drives the key shaft 23 to move up and down precisely, so that the bottle mouth can be accurately aligned with the core column 32 and the mold wheel 31, ensuring constant contact angle and extrusion pressure. In conjunction with the structure of the fixed mold wheel 31, wrinkles and color spots caused by positioning deviation and unstable rotation are further reduced, and the molding accuracy is improved.
[0085] like Figures 1-3 As shown, the lifting actuating component 25 further includes a mounting plate 251, a lifting device 252, and a shift fork 253. The mounting plate 251 is detachably mounted on the side wall of the turntable 10. The lifting device 252 is mounted on the mounting plate 251. The shift fork 253 is mounted on the movable end of the lifting device 252. The actuating end of the shift fork 253 is provided with a self-rotating connecting ring 254. The connecting ring 254 is fixedly sleeved on the key shaft 23.
[0086] In the above scheme, when the bottle height needs to be adjusted, the lifting device 252 is activated to drive the movable end of the fork 253 to rise and fall. The fork 253 drives the key shaft 23 to rise and fall along the keyway of the sleeve 22 through the connecting ring 254 at the actuating end. The key shaft 23 drives the clamping head 24 and the bottle to rise and fall synchronously. When the key shaft 23 rotates with the sleeve 22 and drives the bottle to rotate, the connecting ring 254 can rotate on its own to prevent the fork 253 from rotating with the key shaft 23, thus ensuring the stable state of the lifting device 252 and the fork 253. The mounting plate 251 is detachable to facilitate the maintenance or replacement of the lifting actuating component 25.
[0087] In this embodiment, the connecting ring 254 can rotate, realizing a flexible connection between the lifting actuating component 25 and the rotating key shaft 23. This ensures the effective transmission of lifting force and avoids interference from the rotation of the key shaft 23 on the lifting device 252 and the fork 253, making the bottle lifting more stable and precise. This further improves the positioning accuracy of the bottle mouth with the mold wheel 31 and the core column 32. At the same time, the detachable mounting plate 251 facilitates equipment maintenance, reduces maintenance difficulty and cost, ensures long-term stable operation of the device, and improves production continuity and product quality.
