Description

Technical Field

[0001] The present application relates to the technical field of plastic bottle production equipment, and in particular to an integrated blow molding equipment for plastic bottles. Background Art

[0002] Blow molding is a key process in the large-scale production of plastic bottles. Its core is to use high-pressure gas to inflate the injection-molded tubular parison until it fits the inner wall of the mold, forming a hollow structure.

[0003] Existing blow molding equipment generally consists of an injection molding mechanism, a blow molding mechanism, a blanking mechanism, and a transfer mechanism. The transfer mechanism is primarily used to transport the core rod between the injection molding mechanism, the blow molding mechanism, and the blanking mechanism. The specific production process is as follows: First, the core rod is transferred to the injection molding mechanism, where it is injected into a tubular parison. Second, the core rod is transferred to the blow molding mechanism, where high-pressure gas is introduced into the parison, causing it to expand until it fits the inner surface of the blow mold. It is then cooled and shaped to form a plastic bottle. Finally, the core rod is transferred to the blanking mechanism, which removes the plastic bottle from the core rod.

[0004] When blow molding equipment is changed to produce plastic bottles of different sizes, the injection mold, blow mold, and corresponding core rods need to be replaced. Therefore, when the blow molding equipment needs to frequently change the size of the plastic bottles produced, the core rods have poor applicability due to their fixed size. This requires frequent replacement of core rods of different sizes, which also requires preparing core rods of multiple sizes. This makes it costly for the company to store and manage a large number of core rods. Summary of the Invention

[0005] The present application provides an integrated blow molding device for plastic bottles, the purpose of which is to improve the applicability of a core rod.

[0006] The present application provides an integrated blow molding equipment for plastic bottles, which adopts the following technical solutions: An integrated blow molding device for plastic bottles comprises a rotating frame, with an injection mold, a blow mold, and a blanking mechanism arranged in sequence along its circumference on its outer side; a plurality of core rods are arranged around the rotating frame, and the rotating frame is used to drive the core rods to be sequentially inserted into the injection mold, blow mold, and blanking mechanism, and the core rods are slidably connected to the rotating frame along their own axial direction. An injection cavity is formed between the core rod and the injection mold, and the injection mold is connected to an injection molding machine, which is in communication with the injection cavity; a blow molding cavity is formed between the core rod and the blow mold, and a blowing mechanism is provided on the blow mold. A first blow molding air channel is provided on the core rod, and the blowing mechanism is in communication with the corresponding first blow molding air channel.

[0007] By adopting the above technical solution, based on the coordinated arrangement of a rotating frame, a core rod, an injection mold, an injection machine, a blow mold, an air blowing mechanism, and a blanking mechanism, fully automated blow molding of plastic bottles can be achieved. Because the core rod is axially connected to the rotating frame and slides along its axis, the core rod's length is adjustable, allowing it to adapt to the production requirements of plastic bottles of varying lengths, thereby improving the core rod's applicability. Since the core rod can accommodate the production of a variety of plastic bottles of different sizes, the number of core rods required can be significantly reduced, saving companies the cost of storing and managing the core rods.

[0008] Optionally, it also includes a product transfer mechanism, wherein the unloading mechanism is located between the product transfer mechanism and the rotating frame, and the unloading mechanism is used to remove the product corresponding to the core rod and transfer it to the product transfer mechanism; the product transfer mechanism is provided with a visual inspection mechanism, and the product transfer mechanism is used to transfer the product to the visual inspection mechanism, and the visual inspection mechanism is used to inspect the product.

[0009] By adopting the above technical solution, the unloading mechanism can transfer the plastic bottles to the product transfer mechanism, and the product transfer mechanism can transport the plastic bottles to the visual inspection mechanism, which can realize the automatic unloading and inspection function of the plastic bottles, thereby further improving the production process of the plastic bottles.

[0010] Optionally, the blanking mechanism is also provided with a clamping rod assembly and a horizontal driving member, and the horizontal driving member is connected to the clamping rod assembly; the clamping rod assembly is used to clamp the corresponding core rod or product, and the blanking mechanism is used to drive the clamping rod assembly, and the driving direction of the blanking mechanism is set along the axial direction of the core rod inserted into the blanking mechanism.

[0011] By adopting the above technical solution, the horizontal drive member and the clamping rod assembly cooperate to clamp the product, and the unloading mechanism can drive the clamping rod assembly to move, thereby removing the product from the corresponding core rod. At the same time, the clamping rod assembly can also clamp the core rod, so the unloading mechanism and the clamping rod assembly cooperate to achieve automatic adjustment of the core rod.

[0012] Optionally, a laser ranging mechanism is further included, which is spaced apart from the rotating frame; the blanking mechanism is located between the laser ranging mechanism and the rotating frame, and one end of the core rod inserted into the blanking mechanism is arranged opposite to the laser ranging mechanism, and the laser ranging mechanism is used to detect the axial length of the corresponding core rod.

[0013] By adopting this technical solution, the laser distance measuring mechanism can detect the length of the corresponding mandrel, facilitating the adjustment of multiple mandrels to the same axial length during initial installation. Furthermore, the laser distance measuring mechanism, the clamping assembly, and the blanking mechanism work together to automatically adjust the mandrel length, and a negative feedback control system for mandrel length adjustment is established, further improving the accuracy of mandrel adjustment.

[0014] Optionally, one end of the core rod is coaxially connected to a mounting rod, one end of the mounting rod is provided with a mounting hole, the core rod and the mounting hole are coaxially plugged into each other, and the mounting rod is slidingly connected to the core rod along its own axis; a long ventilation hole is provided on the outer wall of the mounting rod, and the long ventilation hole, the mounting hole and the first blow molding air duct are connected in sequence; the mounting rod is connected to the rotating frame, and when the core rod is inserted into the blow molding mold, the blowing mechanism is connected to the corresponding long ventilation hole.

[0015] By adopting the above technical solution, the installation of the mounting rod enables the installation of the mandrel on the rotating frame. The sliding connection between the mandrel and the mounting plate allows the mandrel's axial length to be adjusted. Furthermore, since the mounting rod is connected to the rotating frame, the position of the vent hole remains unchanged. This ensures that the blowing mechanism is always connected to the vent hole within the blow molding station, and the inflation mechanism is always connected to the corresponding first blow molding air channel, thus ensuring that the blow molding process can proceed normally.

[0016] Optionally, a long ventilation groove is provided on the inner side wall of the mounting hole, the long ventilation hole is connected to the long ventilation groove, and the length direction of the long ventilation groove is arranged along the axial direction of the mounting hole.

[0017] By adopting the above technical solution, since the core rod may block the long ventilation hole when sliding in the mounting rod, after the long ventilation slot is opened, even if the core rod blocks the long ventilation hole, the high-pressure gas introduced into the long ventilation hole by the blowing mechanism can still enter the mounting hole through the long ventilation slot, thereby allowing the high-pressure gas to finally enter the first blow molding air channel.

[0018] Optionally, the core rod includes a core column and several outer sleeves, the inner diameters of the several outer sleeves increase successively, and the several outer sleeves are coaxially plugged in successively, the innermost outer sleeve is coaxially sleeved on the core column, the outermost outer sleeve is coaxially plugged in with the mounting hole, and the first blow molding air duct is opened on the core column; the mounting rod and the adjacent outer sleeves, between two adjacent outer sleeves, and between the core column and the adjacent outer sleeves are all slidably connected and are all provided with locking components.

[0019] By adopting the above technical solution, the mandrel is configured with a core post and several outer sleeves. The outer sleeves can be adjusted by sliding to change the appearance of the mandrel. Specifically, the exposed length of the outer sleeves and core post can be adjusted to change the length of the mandrel. By varying the exposed portion of the outer sleeves, i.e., sliding a portion of the outer sleeves into the mounting holes, the outer diameter of the mandrel can be varied. This further enhances the mandrel's adjustability and, consequently, its applicability.

[0020] Optionally, the first blow molding air channel includes an inner hollow channel, the inner hollow channel is coaxially opened in the core column, and the inner hollow channel passes through the core column.

[0021] By adopting the above technical solution, the hollow air channel runs through the core column, which ensures that the core column can be ventilated normally, thereby ensuring the normal progress of the blow molding step.

[0022] Optionally, a heat-sensitive sealing part is provided on the core column, the heat-sensitive sealing part is located in the air duct, and the heat-sensitive sealing part is made of heat-expanding material; a temperature control component is provided on the core column, and the temperature control component is used to regulate the temperature of the core column; a reset elastic part is provided between the core column and the adjacent outer sleeve, the reset elastic part is axially arranged along the axial direction of the core column, one end of the reset elastic part is connected to the core column, and the other end is connected to the adjacent outer sleeve.

[0023] By adopting this technical solution, since the thermally sensitive sealing member is made of a thermally expandable material, it is controlled by the temperature control assembly. The temperature control assembly regulates the temperature of the core column to control whether the thermally sensitive sealing member undergoes thermal expansion. When this occurs, the thermally sensitive sealing member can seal the air passage.

[0024] During the blow molding process, when the central air passage is closed, the continuously rising internal pressure of the mounting rod pushes the core rod, causing it to extend. This allows the core rod to function as a stretch rod in the injection-blow-stretch process. Once the central air passage is reopened, the reset spring automatically resets the core rod. Therefore, thanks to the combined action of the thermal seal, temperature control assembly, and reset spring, the core rod can choose whether to trigger the stretch rod, thus improving the core rod's applicability.

[0025] Optionally, a seal head is provided at one end of the core column axially away from the mounting rod, the seal head is coaxially connected to the core column, a reserved air hole is provided on the seal head, and the reserved air hole is communicated with the air duct; a hidden ring groove is provided on the seal head toward the side of the core column, a floating ring is provided in the hidden ring groove, the floating ring is slidingly connected to the inner wall of the hidden ring groove along the axial direction of the core column, the floating ring is connected to a thermosensitive drive ring on the side toward the core column, and a font part is connected on the other side, the thermosensitive drive ring is made of thermal expansion material; a font slot is provided through the bottom of the hidden ring groove, the font part is plugged into the font slot, and the font part is slidingly connected to the inner wall of the font slot.

[0026] By adopting the above technical solution, since the thermal drive ring is made of a thermally expandable material, it is controlled by the temperature control assembly. The temperature control assembly's regulation of the core column's temperature can control whether the thermal drive ring undergoes thermal expansion. When the thermal drive ring undergoes thermal expansion, it pushes the floating ring to move, causing the font element to protrude into the font slot, allowing the seal head to function as a seal. Therefore, through the coordination of the thermal sealing element, temperature control assembly, reset elastic element, and seal assembly, it is possible to select whether to mark the product, thereby improving the core rod's applicability.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The present application adopts a design in which the mandrel is slidably connected to the rotating frame along its own axis, so that the length of the mandrel is adjustable, which improves the applicability of the mandrel and enables the mandrel to adapt to the production of plastic bottles of different sizes.

[0028] 2. The present application adopts a core rod structure design in which the diameter and length of the core rod are adjustable, thereby being adaptable to the production of plastic bottles of different sizes, thereby improving the applicability of the integrated blow molding equipment.

[0029] 3. This application expands the function of the core rod through the cooperation of the thermal sealing part, the temperature control component, the reset elastic part and the seal component, so that the core rod can switch between two different blow molding processing methods, and can also choose whether to mark the product, which can improve the applicability of the core rod.

[0047] Reference Figure 3 In the injection molding station, the outer wall of the core rod 5 inserted into the injection mold 2 is spaced apart from the inner wall of the injection mold 2 to form an injection cavity 21. The injection mold 2 is connected to an injection machine 6, which is connected to the injection cavity 21.

[0048] Reference Figure 3 and Figure 4 In the blow molding station, the outer wall of the core rod 5 inserted into the blow mold 3 is spaced apart from the inner wall of the blow mold 3 to form a blow molding cavity 31. The blow mold 3 is provided with a blowing mechanism 7, and the core rod 5 is provided with a first blow molding air channel 51, and the blowing mechanism 7 is connected to the first blow molding air channel 51.

[0049] Reference Figure 1 Under the action of the rotating frame 1, each mandrel 5 can pass through the injection molding station, the blow molding station, and the blanking station in sequence. When the mandrel 5 is in the injection molding station, the injection molding machine 6 injects a tubular preform onto the mandrel 5; when the mandrel 5 is in the blow molding station, the blowing mechanism 7 blows high-pressure gas into the tubular preform, thus completing the blow molding of the plastic bottle; when the mandrel 5 is in the blanking station, the blanking mechanism 4 unloads the plastic bottle mounted on the mandrel 5. The coordinated operation of these devices enables fully automated production of plastic bottles.

[0050] Reference Figure 1 and Figure 2 The rotating frame 1 includes a workbench 11, a triangular rotating frame 12, a lifting drive member, and a rotating drive member.

[0051] In this embodiment, both the lifting drive member and the rotating drive member adopt hydraulic drive mechanisms. Specifically, the lifting drive member adopts a hydraulic push rod, and the rotating drive member adopts a hydraulic rotary motor.

[0052] Due to the arrangement of the spline shaft or sliding coupling between the rotary drive member and the triangular rotating frame 12 , the triangular rotating frame 12 can move in the vertical direction and can also rotate, which enables both the rotary drive member and the lifting drive member to drive the triangular rotating frame 12 .

[0060] In this embodiment, refer to Figure 3 The injection mold 2 is equipped with a heat preservation flow channel, in which a heating medium flows, thereby ensuring the temperature of the injection mold 2 and improving the injection molding quality.

[0061] Reference Figure 1 and Figure 4 The blow mold 3 includes an upper blow mold 32 and a lower blow mold 33. The lower blow mold 33 is arranged on the work platform, and the upper blow mold 32 is located directly above the lower blow mold 33. A blow mold clamping driver 34 is provided on the work table 11.

[0062] In this embodiment, refer to Figure 4 The blow mold 3 is built with a heat-insulating flow channel and a cooling flow channel. A heating medium flows through the heat-insulating flow channel, while a cooling medium flows through the cooling flow channel. By controlling the alternating operation of the heating and cooling media, the deformation quality of the tubular preform is guaranteed during blow molding, and the plastic bottle can be quickly cooled after blow molding. This improves production efficiency and ensures production quality.

[0063] Reference Figure 1 and Figure 4 The blowing mechanism 7 includes an air source and an air pipe 71. The air pipe 71 is connected to the blow molding upper mold 32. A blowing flow channel 72 is opened in the blow molding upper mold 32. A plurality of air injection holes 73 are opened on the lower side wall of the blow molding upper mold 32.

The air injection holes 73 are connected to the corresponding air inlet holes 513 on the core rod 5, and the upper blow mold 32 closes the corresponding air inlet holes 513 on the core rod 5. Based on the design of the blowing mechanism 7 and the core rod 5 structure, the blowing mechanism 7 and the core rod 5 are automatically connected when the blow mold 3 is closed, and the blow molding process can be completed at this time.

[0065] Reference Figure 1 and Figure 5 The blanking mechanism 4 includes a stripping plate 41 , and a plurality of stripping slots 42 are provided on the upper side of the stripping plate 41 . The stripping slots 42 penetrate the stripping plate 41 , and the plurality of stripping slots 42 are sequentially spaced along the length direction of the stripping plate 41 .

[0067] Reference Figure 1 and Figure 5 The blanking mechanism 4 further includes a horizontal drive member 43 and a flip drive member 44. The horizontal drive member 43 is mounted on the workbench 11 and is oriented in the axial direction of the corresponding mandrel 5. The flip drive member 44 is mounted on the horizontal drive member 43 and is connected to the underside of the stripper plate 41. In this embodiment, the horizontal drive member 43 utilizes a ball screw linear module driven by a servo motor, while the flip drive member 44 utilizes an electric motor.

[0068] When the mandrel 5 rotates from the blow molding station to the unloading station, the triangular rotating frame 12 descends. The mandrel 5 and the plastic bottle mounted on the mandrel 5 are then locked into the corresponding demolding slot 42. The demolding slot 42 secures the corresponding plastic bottle. The horizontal drive member 43 then drives the stripper plate 41 to move, removing the plastic bottle from the mandrel 5. The flip drive member 44 then rotates the stripper plate 41 90 degrees, turning the horizontal plastic bottle into a vertical position. The design of the unloading mechanism 4 realizes the unloading function of the plastic bottle.

[0069] Reference Figure 5 and Figure 6 A clamping rod assembly 45 is provided on the stripping plate 41, and the clamping rod assembly 45 includes two fixed plates 451. The fixed plates 451 have the same length direction as the stripping plate 41. The fixed plates 451 are slidingly connected to the stripping plate 41 along their own length direction, and the two fixed plates 451 are superimposed along their own thickness direction.

[0070] Reference Figure 5 and Figure 6 An auxiliary slot 452 is opened on the upper side of the fixed plate 451, and the auxiliary slot 452 is arranged in a one-to-one correspondence with the demoulding slot 42. The auxiliary slot 452 is directly connected to the demoulding slot 42, and the inner wall of the auxiliary slot 452 is flush with the inner wall of the corresponding demoulding slot 42.

[0071] Reference Figure 6 and Figure 7 Two fixed driving members 453 are provided on the stripper plate 41. The fixed driving members 453 are arranged in a one-to-one correspondence with the fixed plates 451. The driving direction of the fixed driving members 453 is set along the length direction of the fixed plates 451. The driving ends of the fixed driving members 453 are connected to the corresponding fixed plates 451. In this embodiment, the fixed driving members 453 are cylinders, electric push rods, or electromagnetic push rods.

[0072] The two fixed drive members 453 work in concert to allow the two fixed plates 451 to move toward each other, thereby offsetting the two auxiliary slots 452 and achieving a clamping function. This allows the unloading mechanism 4 to be more adaptable by clamping plastic bottles of varying sizes. Furthermore, by clamping the mandrels 5 and cooperating with the horizontal drive member 43, the axial lengths of the corresponding mandrels 5 can be automatically adjusted within the unloading station. The accuracy of the adjustment depends on the precision of the horizontal drive member 43.

[0073] In this embodiment, refer to Figure 6 and Figure 7 A fixing plate cavity 454 is provided in the stripping plate 41, and the fixing plate 451 and the fixing driving member 453 are both located in the fixing plate cavity 454.

[0074] Reference Figure 1The blow molding integrated equipment further includes a product transfer mechanism 8, and the unloading mechanism 4 is located between the triangular rotating frame 12 and the product transfer mechanism 8. The product transfer mechanism 8 includes a conveyor belt, and baffles are provided on both sides of the conveyor belt in the width direction.

[0075] Under the action of the unloading mechanism 4, the unloading mechanism 4 turns the plastic bottle to a vertical state and places it on the conveyor belt. The conveyor belt realizes the transportation of the plastic bottle, which can realize the unloading function of the plastic bottle.

[0076] Reference Figure 1 The blow molding integrated equipment further includes a visual inspection mechanism 9 , which is disposed on the conveyor belt, and the conveyor belt passes through the visual inspection mechanism 9 .

[0077] The visual inspection mechanism 9 takes omnidirectional photos of the plastic bottles on the conveyor belt and feeds the photo data back to the controller. The controller compares the captured photo information with the set data and determines whether the corresponding plastic bottles are qualified. Unqualified plastic bottles are marked or sorted, while qualified plastic bottles continue to be transported on the conveyor belt.

[0078] In addition, refer to Figure 1 A laser distance measuring mechanism 10 is provided on the conveyor belt. The laser distance measuring mechanism 10 is provided on the side of the conveyor belt away from the unloading mechanism 4, and the laser distance measuring mechanism 10 is detachably connected to the corresponding baffle.

[0079] In this embodiment, the laser distance measuring mechanism 10 includes several laser sensors. Each mandrel 5 located at the blanking station is associated with a corresponding laser sensor, with the laser sensor positioned directly opposite one end of the corresponding mandrel 5. The laser sensor can detect the axial length of the corresponding mandrel 5, facilitating accurate installation of the mandrel 5.

[0080] In this embodiment, the laser distance measuring mechanism 10 is only used when it is necessary to calibrate the axial length of the core rod 5. During normal production time, the laser distance measuring mechanism 10 needs to be disassembled from the baffle.

[0081] The implementation principle of the embodiment of the present application is: when it is necessary to adapt to the production of plastic bottles of different sizes, loosen the core rod 5, and adjust the length of the core rod 5 extending out of the triangular rotating frame 12 in cooperation with the clamping rod assembly 45 and the horizontal driving member 43, so that the core rod can adapt to the production of plastic bottles of different sizes.

[0082] In addition, there are installation errors during the installation process of the core rod 5 and the injection mold 2, which leads to an error in the distance between the end face of the core rod 5 and the corresponding bottom face of the injection cavity 21. This will cause the bottom thickness of the injection-molded tubular preform to be too thin or too thick, and thus during the blow molding process, the bottom of the blow-molded plastic bottle will appear too thick or too thin, which will lead to the final visual inspection mechanism 9 detecting a large number of unqualified plastic bottles.

[0083] Therefore, when a large number of unqualified plastic bottles are detected, the equipment is shut down, the actual distance between the end face of the core rod 5 and the corresponding bottom surface of the injection cavity 21 is detected, the size of the core rod 5 that needs to be adjusted is determined, and then the laser distance measuring mechanism 10 is reinstalled, the core rod 5 is loosened, and the core rod 5 is adjusted by the cooperation of the clamping rod assembly 45 and the horizontal driving member 43, thereby eliminating installation errors and ensuring the qualified rate of plastic bottles.

[0084] Example 2: A plastic bottle blow molding integrated equipment, referring to Figure 8 and Figure 9 This embodiment differs from Example 1 in that a mounting rod 20 is coaxially mounted on one end of the core rod 5. The mounting rod 20 and the core rod 5 are coaxially and removably connected. One end of the mounting rod 20 coaxially engages with a corresponding mounting hole 121, and the core rod 5 is positioned outside the triangular rotating frame 12. Specifically, the mounting rod 20 and the triangular rotating frame 12 are connected by bolts.

[0085] Reference Figure 8 and Figure 9 A mounting hole 201 is coaxially opened at one end of the mounting rod 20, and the core rod 5 includes a bottle body column 53 and a bottle mouth tube 52. The mounting rod 20, the bottle mouth tube 52 and the bottle body column 53 are coaxially connected in sequence, and the bottle mouth tube 52 is coaxially plugged into the mounting hole 201, and the bottle mouth tube 52 is coaxially slidably connected to the mounting hole 201 along its own axis; similarly, the bottle mouth tube 52 is sleeved on the outside of the bottle body column 53, and the bottle body column 53 is slidably connected to the bottle mouth tube 52 along its own axis.

[0086] A long ventilation hole 202 is formed on the outer wall of the mounting rod 20. The long ventilation hole 202 is connected to the mounting hole 201 and is located outside the triangular rotating frame 12. The first blow molding air channel 51 includes an inner air channel 511 and an air outlet 512. The inner air channel 511 is coaxially formed on the bottle body column 53, and the air outlet 512 is formed at one end of the bottle body column 53.

[0087] Furthermore, the ventilation long hole 202, the mounting hole 201, the middle air passage 511 and the plurality of air outlet holes 512 are connected in sequence.

[0088] Reference Figure 8 and Figure 9The structural design of the mounting rod 20 realizes the connection between the core rod 5 and the triangular rotating frame 12. Moreover, when the core rod 5 is in the blow molding station, the ventilation long hole 202 can be connected with the blowing mechanism 7, which ensures the normal progress of blow molding.

[0089] Reference Figure 8 and Figure 9 The core rod 5 is designed to have a mouthpiece tube 52 that forms the neck of the plastic bottle on the tubular preform. Similarly, the body column 53 forms the body of the plastic bottle on the tubular preform. Therefore, the combination of the body column 53 and mouthpiece tube 52 ensures that the core rod 5 meets the production requirements of plastic bottles.

[0090] Reference Figure 8 and Figure 9 The core rod 5 is designed to cooperate with the mounting rod 20. Since the mounting rod 20, the bottle mouth tube 52 and the bottle body column 53 are coaxially slidably connected in sequence, the length of the bottle mouth tube 52 and the bottle body column 53 can be adjusted, thereby adjusting the shape of the core rod 5, so that the core rod 5 can adapt to the production of different plastic bottles.

[0091] In this embodiment, refer to Figure 9 A ventilation slot 203 is provided on the inner wall of the mounting hole 201 . The length direction of the ventilation slot 203 is arranged along the axial direction of the mounting rod 20 , and the air inlet hole 513 is connected to the ventilation slot 203 .

[0092] Because when adjusting mandrel 5, mandrel 5 may close air inlet slot 513. Therefore, offer ventilation slot 203, make the high pressure gas that passes into ventilation slot 202 enter in mounting hole 201 through ventilation slot 203, this just can guarantee normal blow molding process.

[0093] In this embodiment, refer to Figure 8 and Figure 9 The core rod 5 includes a core column 55 and several outer sleeves 54. The inner diameters of the several outer sleeves 54 increase successively. The several outer sleeves 54 are coaxially plugged in successively. The innermost outer sleeve 54 is coaxially sleeved on the core column 55. The outermost outer sleeve 54 is coaxially plugged in with the mounting hole 201, and the outer sleeve 54 is slidably connected with the adjacent mounting rod 20 or core column 55 or outer sleeve 54 along its own axial direction.

[0094] The outermost outer sleeve 54 and a plurality of adjacent outer sleeves 54 form a bottle mouth tube 52. The core column 55 and a plurality of adjacent outer sleeves 54 form a bottle body column 53.

[0095] Reference Figure 8 and Figure 9Based on the structural arrangement of the mandrel 5, the outer sleeve 54 can be slidably adjusted to change the extension length of the outer sleeve 54. In addition, the number of outer sleeves 54 constituting the bottle mouth tube 52 or the bottle body column 53 can also be changed. This allows the length and outer diameter of the bottle mouth tube 52 or the bottle body column 53 to be adjusted, further increasing the size adjustment range of the mandrel 5 and thus improving the applicability of the mandrel 5.

[0096] In this embodiment, in order to ensure the airtightness of the core rod 5 , elastic sealing rings may be added between the mounting rod 20 and the adjacent outer sleeve 54 , between two adjacent outer sleeves 54 , and between the core column 55 and the adjacent outer sleeve 54 .

[0097] In this embodiment, refer to Figure 9 The air passage 511 is coaxially opened in the core column 55, and the air outlet 512 is opened on the end surface of the core column 55.

[0098] In this embodiment, refer to Figure 9 A locking assembly 56 is provided between the mounting rod 20 and the adjacent outer sleeve 54 , between two adjacent outer sleeves 54 , and between the core column 55 and the adjacent outer sleeve 54 .

[0099] The provision of the plurality of locking assemblies 56 enables locking between the mounting rod 20 and adjacent outer sleeves 54, between two adjacent outer sleeves 54, and between the core column 55 and adjacent outer sleeves 54. Therefore, with the cooperation of the plurality of locking assemblies 56, it is possible to lock the mounting rod 20 and the bottle mouth tube 52, and also to lock the bottle mouth tube 52 and the bottle body column 53. Thus, after the size of the core rod 5 is adjusted, the core rod 5 can be locked, thereby increasing the structural stability of the core rod 5.

[0100] In this embodiment, the locking assembly 56 between the mounting rod 20 and the adjacent outer sleeve 54, the locking assembly 56 between two adjacent outer sleeves 54, and the locking assembly 56 between the core column 55 and the adjacent outer sleeve 54 are all of the same structure. This embodiment is described by taking the locking assembly 56 between the core column 55 and the adjacent outer sleeve 54 as an example.

[0101] Specifically, refer to Figure 9 and Figure 10 The locking assembly 56 includes a set screw 561. A set screw hole 562 is formed through the outer sleeve 54. The set screw 561 is inserted into the set screw hole 562. The set screw 561 is threadedly connected to the inner wall of the set screw hole 562. One end of the set screw 561 contacts the outer wall of the stem 55. The stem 55 can be locked and unlocked by turning the set screw 561.

[0102] Reference Figure 9 and Figure 10A fixing screw hole 562 is also provided on the core column 55. When the end face of the core column 55 is flush with the end face of the adjacent outer sleeve 54, the fixing screw hole 562 on the core column 55 is coaxially arranged with the fixing screw hole 562 of the adjacent outer sleeve 54. At this time, the fixing screw 561 can be inserted into the two fixing screw holes 562, so that the end face of the core column 55 is always flush with the end face of the adjacent outer sleeve 54.

[0103] Reference Figure 9 and Figure 10 An elastic rubber block 563 is inserted into the fastening screw hole 562. When the fastening screw hole 562 is exposed, the corresponding elastic rubber block 563 is inserted into the exposed fastening screw hole 562. The outer wall of the elastic rubber block 563 is flush with the outer wall of the corresponding outer sleeve 54 or the outer wall of the core column 55.

[0104] The principle of this embodiment is as follows: when the size of the plastic bottles being produced needs to be adjusted, or when the production cost of the plastic bottles needs to be adjusted (i.e., the thickness of the tubular preforms injected in the injection molding station is adjusted to control material costs), the size of the core rod 5 is determined as needed. After this, the mounting rod 20 and core rod 5 are removed, or the corresponding locking assembly 56 is unlocked. Then, the corresponding outer sleeves 54 and core rods 55 are adjusted to form the core rod 5 of the corresponding size.

[0105] Moreover, since both the core column 55 and the outer sleeve 54 can be slidably adjusted, the length of the entire core rod 5 can be adjusted, so that the length and outer diameter of the core rod 5 can meet the requirements of different injection molds 2, and the length of the core rod 5 can be adjusted to eliminate installation errors and improve the quality of the injection molded tubular blank.

[0106] Example 3: A plastic bottle blow molding integrated equipment, referring to Figure 11 and Figure 12 The difference between this embodiment and embodiment 2 is that a long threading hole 204 is further opened on the outer wall of the mounting rod 20, and the long threading hole 204 and the long air inlet hole 513 are spaced apart along the axial direction of the mounting rod 20. The long threading hole 204 is connected to the mounting hole 201, and the long threading hole 204 is located in the triangular rotating frame 12. The inner wall of the mounting circular hole 121 closes the long threading hole 204.

[0107] In this embodiment, the upper side of the triangular rotating frame 12 is provided with a plurality of threading openings, each corresponding to the mounting circular holes 121 and communicating with the corresponding threading slots 204. Sealing plates are inserted into the threading openings, sealing the corresponding threading openings. The sealing plates are provided with threading holes extending through the sealing plates, each of which is fitted with a sealing rubber ring.

[0108] Based on the coordinated setting of the threading port, sealing plate and threading hole, the wire in the core rod 5 can be passed through the threading long hole 204. At the same time, the sealing plate and the sealing rubber ring are used to close the threading port to ensure the sealing during the blow molding stage.

[0109] In this embodiment, to ensure the feasibility of this solution, the control device can be built into the triangular rotating frame 12, thereby ensuring that the rotation of the triangular rotating frame 12 does not affect the electrical control inside the core rod 5. In addition, the power supply of the control device can adopt the slip ring brush solution or wireless transmission technology commonly used in the prior art.

[0110] Reference Figure 12 and Figure 13 A heat-sensitive blocking member 57 is provided at one end of the core column 55 facing the mounting rod 20 . The heat-sensitive blocking member 57 is made of a heat-expanding material and is located in the central air passage 511 .

[0111] Reference Figure 12 and Figure 13 The core 55 is provided with a temperature control assembly 58, which includes a semiconductor cooling tube 582 and several electric heating rods 581. The electric heating rods 581 are inserted into the core 55 and are evenly spaced along the circumference of the core 55, arranged in a circular pattern. The semiconductor cooling tube 582 is sleeved on the outer wall of the core 55 and located between the core 55 and the adjacent outer sleeve 54. The semiconductor cooling tube 582 is fixedly connected to the core 55 and slidably connected to the adjacent outer sleeve 54.

[0112] The temperature control assembly 58 is provided with an electric heating rod 581 to increase the temperature of the core rod 55. The temperature control assembly 58 is provided with a semiconductor cooling tube 582, and the inner wall of the semiconductor cooling tube 582 is cooled to cool the core rod 5. Therefore, under the control of the temperature control assembly 58, the temperature of the core rod 55 can be controlled.

[0113] Reference Figure 13 When the temperature control component 58 regulates the temperature of the core column 55, when the temperature of the core column 55 rises to exceed the phase change temperature of the thermal sealing component 57, the thermal sealing component 57 will expand and deform significantly, thereby closing the air duct 511; on the contrary, after the temperature of the core column 55 drops, the thermal sealing component 57 returns to its original state and the air duct 511 is opened.

[0114] Reference Figure 12 and Figure 13 In the blow molding station, after the central air passage 511 is blocked, high-pressure gas is introduced into the mounting rod 20, increasing the internal pressure therein. This pushes the core 55 outward, allowing the core 55 to stretch the tubular parison. Even after the central air passage 511 is opened, the core 55 still functions as a blow molding machine.

[0115] Reference Figure 12 and 13A reset assembly 59 is provided between the core column 55 and the adjacent outer sleeve 54. The reset assembly 59 comprises a slip ring 591, an end ring 592, and a reset elastic member 593. The slip ring 591 is coaxially sleeved on the outside of the core column 55 and is fixedly connected to the core column 55. The slip ring 591 is inserted into the corresponding outer sleeve 54 and is spaced or slidably connected to the inner sidewall of the corresponding outer sleeve 54 along its own axis. The end ring 592 is coaxially sleeved on the outside of the core column 55 and is coaxially spaced from the slip ring 591. The end ring 592 is located on the side of the slip ring 591 away from the mounting rod 20 and is coaxially connected to one end of the corresponding outer sleeve 54. The reset elastic member 593 is sleeved on the outside of the core column 55 and is located between the end ring 592 and the slip ring 591. One end of the reset elastic member 593 contacts the end ring 592, and the other end contacts the slip ring 591. In this embodiment, the reset elastic member 593 is made of a spring or a tube made of elastic material.

[0116] The sliding ring 591, the end ring 592, and the resetting elastic member 593 cooperate to compress the resetting elastic member 593 as the stem 55 extends outward. Once the air passage 511 is opened, the pressure inside and outside the mounting rod 20 gradually equalizes, and the resetting elastic member 593 automatically returns the stem 55 to its initial position.

[0117] Therefore, refer to Figure 12 and 13 With the cooperation of the heat-sensitive sealing member 57 , the temperature control component 58 and the reset component 59 , the core column 55 can choose whether to trigger the operation of the stretching rod, which can improve the applicability of the core rod 5 .

[0118] Reference Figure 12 and Figure 13 An adjusting ring 510 is also provided between the core rod 5 and the outer sleeve 54. The innermost outer sleeve 54 is sleeved on the outside of the adjusting ring 510. The innermost outer sleeve 54 and the adjusting ring 510 are connected by threads. The core column 55 contacts the adjusting ring 510 along its own axial direction toward one end of the mounting rod 20.

[0119] When the adjustment ring 510 is rotated, the adjustment ring 510 moves along its own axial direction, thereby changing the initial position of the stem 55. This design, on the one hand, can change the initial pressure of the return spring 593 on the stem 55; on the other hand, changing the initial position of the stem 55 allows the core rod 5 to still extend out of the adjacent outer sleeve 54 in the initial state, thus preserving the adjustment range of the core rod 5 and reducing the impact on the adaptability of the core rod 5.

[0120] Reference Figure 13 and Figure 14The mandrel 5 is further provided with a stamp assembly 520 at one end thereof, which is axially away from the adjustment ring 510. The stamp assembly 520 includes a stamp head 5201, which is coaxially and detachably connected to the mandrel 5. The stamp head 5201 has a reserved air hole 5202 formed therein, which is connected to the air passage 511. A hidden annular groove 5203 is formed on the side of the stamp head 5201 facing the core column 55. The hidden annular groove 5203 is coaxially arranged with the reserved air hole 5202. A font slot 5204 is formed at the bottom of the hidden annular groove 5203, which extends through the stamp head 5201.

[0121] Reference Figure 13 and Figure 14 The seal assembly 520 further includes a font member 5205, a floating ring 5206, and a thermal drive ring 5207. The floating ring 5206 is coaxially inserted into the hidden ring groove 5203 and is slidably connected to the inner sidewall of the hidden ring groove 5203 along its own axis. The font member 5205 is disposed on the side of the floating ring 5206 facing the seal head 5201. The font member 5205 is pluggably engaged with the font groove 5204 and is slidably connected to the inner sidewall of the font groove 5204 along the axis of the hidden ring groove 5203. The thermal drive ring 5207 is disposed between the floating ring 5206 and the end surface of the stem 55 and is connected to the floating ring 5206.

[0122] When the temperature control assembly 58 raises the temperature of the stem 55 to a point above the phase transition temperature of the thermal drive ring 5207, the thermal drive ring 5207 expands due to the heat, thereby driving the floating ring 5206 to move. This causes the font element 5205 to move out of the font slot 5204, and the seal head 5201 can now function as a seal. Conversely, when the temperature control assembly 58 lowers the temperature of the stem 55, the thermal drive ring 5207 returns to its original position, causing the floating ring 5206 to return to its original position, and the font element 5205 to disappear into the font slot 5204. At this point, the seal head 5201 no longer functions as a seal.

[0123] Therefore, refer to Figure 13 and Figure 14 With the cooperation of temperature control assembly 58 and stamp assembly 520, the stamp head 5201 on the core column 55 can choose whether to realize the marking function. When marking is needed, the core column 55 is extended and the stamp head 5201 marks the bottom of the blow-molded plastic bottle.

[0124] In this embodiment, a tiny spring is further provided on the side of the floating ring 5206 facing the font element 5205 . The provision of the tiny spring can improve the stability and speed of the resetting of the floating ring 5206 .

[0125] In this embodiment, both the thermosensitive driving ring 5207 and the thermosensitive sealing member 57 are made of thermal expansion material, and the phase transition temperature of the thermosensitive sealing member 57 is lower than the phase transition temperature of the thermosensitive driving ring 5207. Specifically, the thermal expansion material can be a metal thermal expansion body, a shape memory alloy, or a bimetallic strip.

[0126] In this embodiment, refer to Figure 12 A laser displacement sensor 530 is installed within the mounting rod 20, with its detection end facing the end face of the stem 55. During the movement of the stem 55, the laser displacement sensor 530 can monitor the extension speed and length of the stem 55 in real time. This allows the laser displacement sensor 530 to work in conjunction with the air blowing mechanism 7 to form a negative feedback control system, thereby increasing the extension speed and accuracy of the stem 55.

[0127] The implementation principle of the embodiment of the present application is: during normal injection-blow production of plastic bottles, the overall temperature of the core rod 5 is regulated by the temperature control component 58 so that the temperature of the core rod 5 is constant, thereby ensuring that the injection molding effect of the tubular preform is consistent.

[0128] When injection stretch blow molding is required, when the core rod 5 moves into the blow molding station, the air channel 511 is blocked, and the core column 55 is extended, thereby achieving the stretching of the tubular preform; after that, the air channel 511 is opened and the core column 55 is automatically reset.

[0129] When it is necessary to mark the inside of a blow-molded plastic bottle, when the core rod 5 is moved to the blow-molding station and the blow-molding of the plastic bottle is completed, the air duct 511 is blocked, and the font part 5205 protrudes from above the stamp head 5201. At this time, the core column 55 can extend and allow the stamp head 5201 to mark the corresponding mark on the bottom of the plastic bottle; after this, the air duct 511 is reopened, and the font part 5205 is hidden in the font slot 5204. At this time, the core column 55 is automatically reset.

[0130] With the cooperation of the thermosensitive sealing member 57 , the temperature control assembly 58 , the reset assembly 59 and the seal assembly 520 , the core rod 5 can realize the free switching of multiple functions through the regulation of the temperature control assembly 58 , thereby improving the applicability of the core rod 5 .

[0131] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
