Description

Technical Field

[0001] The present invention relates to the technical field of bottle blowing, and in particular to a lifting and transferring embryo mechanism and a embryo heating device. Background Art

[0002] In the packaging industry, large quantities of plastic bottles are often required for filling. Blow molding is the primary production method for plastic bottles due to its simplicity and low cost. In a blow molding production line, the preforms are first heated in a preform heating chamber. Once the preforms reach a certain temperature, a blow molding machine is used to blow the preforms into plastic bottles.

[0003] Currently, existing preforms require a preform lifting mechanism to insert the preforms into the warming chamber. While the preforms are being heated in the warming chamber, a rotating mechanism is required to rotate the preforms to prevent local overheating. Existing preform warming devices use two separate mechanisms, namely the preform rotating mechanism and the preform lifting mechanism, which takes up a lot of space and is costly.

[0049] In the description of the present invention, terms such as "upper," "lower," "left," and "right" are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0050] Figure 1 FIG. 1 shows a schematic structural diagram of the handle blank 100 provided in this embodiment. Figure 1As shown, the handle blank 100 includes a blank body 101 and a handle 102 provided on the upper end of the blank body 101. After heating and blowing, the blank body 101 is blown into the bottle body of the plastic bottle, and the handle 102 remains as it is.

[0051] This embodiment provides a preform heating device that can be used to heat handle preforms 100 or handleless bottle preforms. It can realize automatic preform feeding, automatic heating and automatic preform removal, with a compact operation process, high equipment utilization and high production efficiency.

[0052] Figure 2 FIG. 1 shows a schematic structural diagram of the preform heating device provided in this embodiment. Figure 2 As shown, the preform heating device includes a preform feeding module 1, a carrying mechanism 2, a heating mechanism 3, a lifting and transferring mechanism 4, an air cooling module 5 and a preform retrieval robot 6. The preform feeding module 1 is used to automatically convey the handle preform 100; the carrying mechanism 2 serves as the mounting structure of the heating mechanism 3 and the lifting and transferring mechanism 4, and can drive the heating mechanism 3 and the lifting and transferring mechanism 4 to rotate synchronously; the lifting and transferring mechanism 4 is used to receive the handle preform 100 conveyed by the preform feeding module 1 and transfer the handle preform 100 to the heating mechanism 3 for heating; the heating mechanism 3 is used to heat the handle preform 100, and the air cooling module 5 is used to exhaust the heating mechanism 3 to prevent local overheating of the handle preform 100 during the heating process; the preform retrieval robot 6 is used to take out the handle preform 100 heated to a certain temperature and transfer it to the bottle blowing machine for blowing operation.

[0053] Continue as Figure 2 As shown, multiple heating mechanisms 3 are arranged at intervals along the circumference of the transport mechanism 2, and the heating mechanism 3 includes a heating barrel 31; multiple lifting and transferring embryo mechanisms 4 are arranged at intervals along the circumference of the transport mechanism 2 and correspond one-to-one to the heating mechanism 3, and the lifting and transferring embryo mechanisms 4 are used to receive the handle embryo 100 conveyed by the embryo feeding module 1, and insert the embryo body 101 into the heating barrel 31, and the handle 102 is located outside the heating barrel 31.

[0054] Continue as Figure 2As shown, the air cooling module 5 includes a main exhaust pipe 51 and multiple air cooling mechanisms 52. The main exhaust pipe 51 is located in the middle of the carrier mechanism 2. The multiple air cooling mechanisms 52 are spaced apart along the circumference of the carrier mechanism 2, and the air outlets of the multiple air cooling mechanisms 52 are connected to the main exhaust pipe 51. One air cooling mechanism 52 can exhaust air from multiple heating barrels 31, preventing local overheating of the handle blank 100, reducing the number of air cooling mechanisms 52, and lowering equipment costs. For example, the main exhaust pipe 51 extends perpendicular to the carrier mechanism 2, that is, the centerline of the main exhaust pipe 51 coincides with the rotation axis of the carrier mechanism 2. The air cooling mechanism 52 is connected to the bottom of the heating barrel 31 for exhaust, thereby extracting the hot air from the heating barrel 31 from the bottom of the heating barrel 31, which can prevent the hot air from heating the blank opening of the heating barrel 31 and preventing the blank opening from being deformed due to heat. Compared with the prior art of extracting air from the top of the heating box, extracting air from the bottom has a better cooling effect, can avoid the embryo mouth from being deformed by heat, and improve the yield rate.

[0055] Figure 3 FIG. 1 shows a schematic structural diagram of the embryo feeding module 1 provided in this embodiment. Figure 3 Combine Figure 2 As shown, the embryo feeding module 1 includes an embryo feeding mechanism 11, a transition mechanism 12 and an orienting mechanism 13. The embryo feeding mechanism 11 is used to receive the handle embryo 100 on the conveyor line and convey the handle embryo 100 to the transition mechanism 12. The transition mechanism 12 is used to convey the handle embryo 100 to the orienting mechanism 13. The orienting mechanism 13 is used to adjust the direction of the handle 102 of the handle embryo 100 and convey the handle embryo 100 to the lifting and embryo transfer mechanism 4.

[0056] Figure 4 FIG. 2 shows a schematic structural diagram of the transport mechanism 2 provided in this embodiment. Figure 4 As shown, the carrying mechanism 2 includes a frame 21, a carrying plate 22, and a carrying plate drive assembly 23. The carrying plate 22 is rotatably mounted on the frame 21, and the carrying plate drive assembly 23 is used to drive the carrying plate 22 to rotate relative to the frame 21. The carrying plate 22 includes an upper plate body 221, a connecting member 222, and a lower plate body 223. The diameter of the upper plate body 221 is larger than the diameter of the lower plate body 223. A plurality of connecting members 222 are connected between the upper plate body 221 and the lower plate body 223.

[0057] Exemplarily, the main exhaust pipe 51 of the air-cooling module 5 is disposed in the middle of the lower plate 223 of the carrier plate 22 , and the center line of the main exhaust pipe 51 coincides with the center line of the lower plate 223 .

[0058] Figure 5 The schematic diagram shows the structure of the embryo transfer mechanism 4 provided in this embodiment installed on the carrier plate 22. Figure 6 FIG. 4 shows a partial schematic diagram of the embryo transfer mechanism 4 provided in this embodiment being installed on the carrier plate 22. Figure 5-Figure 6As shown, the embryo transfer mechanism 4 includes a bracket 41, an embryo insertion assembly 42, and a lifting drive assembly 43. The bracket 41 is fixed to the carrier plate 22. The embryo insertion assembly 42 includes a lifting seat 421 and an embryo insertion member 422. The lifting seat 421 is slidably mounted on the bracket 41. The embryo insertion member 422 is mounted on the lifting seat 421 and positioned above the heating barrel 31. The lifting drive assembly 43 is used to drive the lifting seat 421 to rise and fall relative to the bracket 41 so that the embryo insertion member 422 can be inserted into the handle embryo 100 on the embryo module 1 and the embryo body 101 of the handle embryo 100 can be inserted into the heating barrel 31. For example, the bracket 41 is fixed to the upper plate 221 of the carrier plate 22.

[0059] The embryo transfer mechanism 4 further includes a guide assembly 44, which includes a slide rail 441 and a slider 442 that slidably cooperate. The slide rail 441 is vertically fixed to the bracket 41, and the slider 442 is used to mount the lift base 421. The arrangement of the guide assembly 44 ensures that the lift base 421 can be stably raised and lowered along the slide rail 441.

[0060] The lifting drive assembly 43 includes a guide rail 431 and a reset member 432. The guide rail 431 includes an ascending section and a descending section. The lifting seat 421 can ascend along the ascending section of the guide rail 431 and descend along the descending section of the guide rail 431 under the action of the reset member 432 during the descending section of the guide rail 431. The raising and lowering of the lifting seat 421 can drive the riser 422 up and down. During the descent of the riser 422, the riser 422 is inserted into the handle 100 and the handle 100 is inserted into the heating barrel 31. During the ascending of the riser 422, the riser 422 drives the handle 100 out of the heating barrel 31 and the riser 422 is separated from the handle 100.

[0061] Optionally, the reset member 432 is a linear actuator, the reset member 432 is mounted on the bracket 41, and the output end of the reset member 432 is connected to the lifting seat 421. Exemplarily, the reset member 432 can be a linear cylinder, a linear hydraulic cylinder, or a linear motor, etc. Preferably, when the reset member 432 is a linear actuator, the output end of the reset member 432 is hinged to the lifting seat 421, which can be through a floating connection, a hinge connection, or a ball joint connection. Of course, in other embodiments, the reset member 432 can also be a high-strength reset spring, which is in a stretched state when the lifting seat 421 rises, so that when the lifting seat 421 moves to the descending section of the guide rail 431, the spring can pull the lifting seat 421 down.

[0062] In order to prevent the inserting piece 422 from moving downward infinitely under the drive of the resetting piece 432 , a limit plate is installed at the upper end of the inserting piece 422 to limit the descending position of the inserting piece 422 .

[0063] Preferably, the embryo insertion assembly 42 further includes a follower wheel 423, which is rotatably mounted on the lifting seat 421. The wheel surface of the follower wheel 423 can abut against the lifting drive member, thereby ensuring that the lifting seat 421 can stably rise and fall along the guide rail 431, while reducing the friction between the lifting seat 421 and the guide rail 431.

[0064] Figure 7 FIG. 4 shows a partial cross-sectional view of the embryo transfer mechanism 4 provided by the present invention. Figure 7 Combine Figure 6 As shown, the lifting and rotating embryo mechanism 4 also includes a rotary drive component 45, and the embryo inserting piece 422 is rotatably mounted on the lifting seat 421. The rotary drive component 45 is used to drive the embryo inserting piece 422 to rotate to ensure that the handle embryo 100 is heated evenly during the heating process to avoid local overheating.

[0065] The embryo insertion component 422 includes a connected embryo insertion head 4222 and a lifting and rotating shaft 4221. The lifting and rotating shaft 4221 and the lifting seat 421 are rotatably engaged via a bearing. For example, the embryo insertion head 4222 and the lifting and rotating shaft 4221 are connected via a slot or keyway, enabling the embryo insertion head 4222 and the lifting and rotating shaft 4221 to rotate synchronously. The embryo insertion head 4222 can be a conventional embryo insertion head in the prior art, for example, an embryo insertion head including a first part and a second part, the second part being mounted on the first part, an O-ring being provided between the second part and the first part, the second part being used to plug into the bottle mouth of the preform, and the second part being an expansion part. The elastic deformation of the O-ring allows the second part to be smoothly inserted and tightened within the bottle mouth of the preform. Examples are not provided here one by one.

[0066] Optionally, the rotary drive assembly 45 includes a rotary driver 451, an input gear 452, an output gear 453, and a sliding sleeve 454. The rotary driver 451 is mounted on the bracket 41 and is used to drive the input gear 452 to rotate. The output gear 453 meshes with the input gear 452, and the sliding sleeve 454 is in transmission connection with the output gear 453. The lifting rotary shaft 4221 of the insert 422 is slidably disposed within the sliding sleeve 454 and can rotate with the sliding sleeve 454, and can be raised and lowered relative to the sliding sleeve 454. It is worth noting that the transmission connection between the sliding sleeve 454 and the output gear 453 can be achieved by fixing the sliding sleeve 454 within the output gear 453 or by mating the sliding sleeve 454 and the output gear 453 via a keyway, as long as the sliding sleeve 454 rotates with the output gear 453.

[0067] Exemplarily, the lifting shaft 4221 and the sliding sleeve 454 are mated via a straight keyway or a flat drive. When the lifting seat 421 drives the inserting member 422 up and down, the inserting member 422 can be raised and lowered relative to the sliding sleeve 454 and the output gear 453, thereby enabling the inserting head 4222 of the inserting member 422 to insert, insert, remove, and remove the embryos from the barrel. When the output gear 453 drives the sliding sleeve 454 to rotate, the lifting shaft 4221 can also drive the inserting head 4222 to rotate, allowing the handle embryo 100 to rotate with the inserting head 4222, ensuring uniform heating of the handle embryo 100. Furthermore, the lifting shaft 4221 and the inserting head 4222 are coaxially arranged, concentrating the lifting and rotational movements on the same axis. This results in a compact structure, and the lifting and rotational movements are independent and non-interfering.

[0068] For example, the rotary driver 451 can use a motor with an encoder. Through program control, the rotary driver 451 drives the lifting and rotating shaft 4221 to drive the embryo insertion head 4222 to rotate forward, reverse, or at a variable speed within the heating barrel 31, ensuring that the handle embryo 100 is evenly heated. The encoder can be used to adapt to different embryo transfer requirements. In addition, the lifting and embryo transfer mechanism 4 can accurately locate the direction of the handle 102 of the handle embryo 100 during the heating of the handle embryo 100 by the heating barrel 31, avoiding heating of the handle 102. Each heating barrel 31 is connected to an air cooling mechanism 52, which is used to extract air from the heating barrel 31 to prevent local overheating of the handle embryo 100.

[0069] Continue as Figure 7 As shown, the lifting rotating shaft 4221 is rotatably connected to the lifting seat 421 through a bearing. A retaining spring is provided on the lifting rotating shaft 4221, which fixes the lifting rotating shaft 4221 to the bearing through the retaining spring, so that the lifting rotating shaft 4221 can be lifted and lowered synchronously when the lifting seat 421 is lifted and lowered.

[0070] Figure 8 FIG. 4 shows a schematic structural diagram of the guide rail 431 provided in this embodiment. Figure 8As shown, the guide rail 431 includes a barrel-removing section 43112, a embryo-removing section 43121, a embryo-entering section 43131 and a barrel-entering section 43116 which are arranged in sequence along the rotation direction of the carrier plate 22. The barrel-removing section 43112 and the embryo-removing section 43121 are both arc-shaped sections that rise along the rotation direction of the carrier plate 22, and the embryo-entering section 43131 and the barrel-entering section 43116 are both arc-shaped sections that descend along the rotation direction of the carrier plate 22. The lifting seat 421 can be lifted and lowered along the guide rail 431. Since the lifting seat 421 slides in cooperation with the slide rail 441 on the bracket 41 through the slider 442, when the carrying plate 22 rotates, the lifting seat 421 can rise along the slide rail 441 under the action of the barrel-removing section 43112 and the embryo-removing section 43121 of the guide rail 431; when the carrying plate 22 continues to rotate, the lifting seat 421 can descend along the embryo-entering section 43131 and the barrel-entering section 43116 of the guide rail 431 under the drive of the reset member 432.

[0071] The lifting nodes of the lifting and lowering movement of the embryo inserting part 422 of the embryo transfer mechanism 4 need to be precisely positioned and coordinated with the handle embryo 100 delivered by the embryo feeding module 1 and the clamping end of the embryo retrieval robot 6, so that the handle embryo 100 can be accurately inserted and transferred into the heating barrel 31 or detached from the handle embryo 100 so that the embryo retrieval robot 6 can take away the handle embryo 100. Specifically, along the rotation direction of the carrying plate 22, the starting end of the embryo stripping section 43121 of the guide rail 431 should be aligned with the clamping end of the embryo retrieval robot 6. The clamping end of the embryo retrieval robot 6 first clamps the handle embryo 100, and then when the lifting seat 421 rises with the embryo stripping section 43121, the embryo insertion head 4222 separates from the handle embryo 100, and the embryo retrieval robot 6 transfers the handle embryo 100 to the bottle blowing machine; the end of the embryo feeding section 43131 of the guide rail 431 should be aligned with the handle embryo 100 conveyed by the embryo feeding module 1. When the lifting seat 421 descends along the embryo feeding section 43131, the embryo insertion head 4222 on the lifting seat 421 can just be inserted into the handle embryo 100 conveyed by the embryo feeding module 1, completing the embryo insertion head 4222 receiving the handle embryo 100.

[0072] After the entire preform heating device is assembled, due to installation errors or processing errors of parts, the guide rail 431 is likely to be misaligned with the preform feeding module 1 and the preform removal robot 6. At this time, whether adjusting the position of the entire guide rail 431 or adjusting the position of the preform feeding module 1 and the preform removal robot 6, it is not convenient to operate, and it is easy to misalign at one time, requiring multiple adjustments and repeated alignments, which not only increases the workload of workers but also reduces the work efficiency.

[0073] In order to solve the above problems, the embryo stripping section 43121 and the embryo entry section 43131 of the guide rail 431 are designed to be position-adjustable. By separately adjusting the position of the embryo stripping section 43121 and / or the embryo entry section 43131, the embryo stripping section 43121 can be aligned with the embryo removal robot 6, and the embryo entry section 43131 can be aligned with the embryo entry module 1. This is not only convenient for adjustment, but also has high adjustment efficiency, and is convenient for repeated adjustments.

[0074] Optionally, the guide rail 431 includes a main body 4311, with both ends of the main body 4311 fixed to the frame 21. The main body 4311 is provided with a barrel removal section 43112 and a barrel entry section 43116. The guide rail 431 also includes a first adjustment portion 4312, which is provided with a billet removal section 43121. The mounting position of the first adjustment portion 4312 on the main body 4311 is adjustable. The guide rail 431 also includes a second adjustment portion 4313, which is provided with a billet entry section 43131. The mounting position of the second adjustment portion 4313 on the main body 4311 is adjustable. In this embodiment, the guide rail 431 includes a main body 4311, a first adjusting part 4312 and a second adjusting part 4313. The first adjusting part 4312 is provided with a embryo stripping section 43121. The installation position of the first adjusting part 4312 on the main body 4311 is adjustable along the rotation direction of the carrier plate 22 to adjust the distance between the embryo stripping section 43121 and the barrel stripping section 43112 along the rotation direction of the carrier plate 22; the second adjusting part 4313 is provided with a embryo entry section 43131. The installation position of the second adjusting part 4313 on the main body 4311 is adjustable along the rotation direction of the carrier plate 22 to adjust the distance between the embryo entry section 43131 and the barrel entry section 43116 along the rotation direction of the carrier plate 22.

[0075] Figure 9 FIG. 4 shows a partial schematic diagram of the guide rail 431 provided in this embodiment. Figure 9 Combine Figure 8As shown, the main body 4311 includes, in sequence, a first horizontal section 43111, a barrel removal section 43112, a second horizontal section 43113, a third horizontal section 43114, a fourth horizontal section 43115, a barrel entry section 43116, and a fifth horizontal section 43117. The first and fifth horizontal sections 43111, 43117 are both fixed to the frame 21. The second and third horizontal sections 43113, 43114 are connected by a step-like structure, and a first adjustment slot is defined in the connecting area. The length of the first adjustment slot is greater than that of the first adjustment portion 4312, which is fixed within the first adjustment slot so as to be adjustable along its length. For example, the first adjustment portion 4312 is provided with an elongated hole extending in the direction of rotation of the carrier tray 22, and a through hole is provided within the first adjustment slot, allowing for adjustment of the position of the first adjustment portion 4312 within the first adjustment slot. Similarly, the third horizontal section 43114 and the fourth horizontal section 43115 are connected in a stepped manner, and a second adjustment slot is defined in the connecting area. The length of the second adjustment slot is greater than the length of the second adjustment portion 4313, and the second adjustment portion 4313 is fixed within the second adjustment slot so as to be adjustable along its length. For example, the second adjustment portion 4313 is provided with an elongated hole extending in the direction of rotation of the carrier plate 22, and a through hole is defined within the second adjustment slot, thereby enabling adjustment of the position of the second adjustment portion 4313 within the second adjustment slot. Preferably, the first adjustment portion 4312 has two elongated holes, corresponding to two through holes; the second adjustment portion 4313 has two elongated holes, corresponding to two through holes.

[0076] Furthermore, the height difference between the second horizontal section 43113 and the first horizontal section 43111 is greater than the height difference between the third horizontal section 43114 and the second horizontal section 43113, that is, the height span of the barrel removal section 43112 is greater than the height span of the embryo removal section 43121. The height difference between the fifth horizontal section 43117 and the fourth horizontal section 43115 is greater than the height difference between the fourth horizontal section 43115 and the third horizontal section 43114, that is, the height span of the barrel entry section 43116 is greater than the height span of the embryo entry section 43131.

[0077] Figure 10 FIG. 5 shows a schematic diagram of the structure of the heating mechanism 3 and the air cooling mechanism 52 provided in this embodiment. Figure 10 As shown, the heating mechanism 3 further includes a mounting base 32 fixed to the bracket 41. The heating barrel 31 is mounted on the mounting base 32, and the heating barrel 31 and the inserting member 422 are coaxially arranged. In other embodiments, the heating mechanism 3 can be directly mounted on the carrier plate 22, as long as the inserting member 422 of the lifting and transferring mechanism 4 can insert the handle blank 100 into the heating barrel 31 of the heating mechanism 3.

[0078] Optionally, the heating barrel 31 includes a heating housing and heating lamps, wherein the heating lamps are partially housed within the heating housing, and a plurality of heating lamps are spaced apart along the length of the heating housing. The body 101 of the handle blank 100 is inserted into the heating housing and positioned between the heating lamps, and the body 101 of the handle blank 100 is heated by the heating lamps.

[0079] The heating shell is a shell structure that penetrates from top to bottom. Under the action of the insert 422, the handle blank 100 is inserted into the heating shell from the upper end of the heating shell. The air cooling module 5 is connected to the bottom of the heating shell and draws air from the bottom of the heating shell to avoid excessive local temperature in the heating shell.

[0080] Continue as Figure 10 As shown, the air cooling mechanism 52 includes a fan 521, an exhaust pipe 522 and an exhaust box 523. One end of the exhaust pipe 522 is connected to the air outlet of the fan 521, and the other end is connected to the main exhaust pipe 51; the exhaust box 523 is connected to the air inlet of the fan 521, and a plurality of air ducts 52321 are provided on the exhaust box 523. The heating barrel 31 is installed on the air duct 52321 and is connected to the air duct 52321. Figure 10 In the embodiment, one air cooling mechanism 52 includes six air ducts 52321, each of which is connected to a heating barrel 31. Of course, in other embodiments, any number of air ducts 52321 can be provided on the exhaust box 523 of one air cooling mechanism 52. The specific number of air ducts 52321 can be determined based on the size of the exhaust box 523 and the power of the fan 521, and is not limited here. This configuration can reduce the number of fans 521, lowering equipment costs, while also facilitating the fabrication, manufacturing, and installation of the air cooling mechanism 52.

[0081] For example, the heating barrel 31 is connected to the air duct 52321 via a bellows 524. Connection via the bellows 524 can compensate for processing or installation errors and facilitate installation operations.

[0082] Figure 11 FIG. 5 shows a schematic structural diagram of the exhaust box 523 provided in this embodiment. Figure 11 As shown, the exhaust box 523 includes a connecting portion 5231 and a bellows portion 5232. The connecting portion 5231 is connected to the air inlet of the fan 521. The bellows portion 5232 is provided with an air duct 52321. The bellows portion 5232 is fan-shaped. The bellows portions 5232 of multiple air-cooling mechanisms 52 are spliced ​​into a circular shape. This arrangement can fully utilize the space below the upper plate 221 of the carrier plate 22. As can be seen, the design of the carrier plate 22 including a large-diameter upper plate 221 and a small-diameter small plate facilitates the installation of the embryo transfer mechanism 4 and the heating mechanism 3, while also facilitating the installation of the main exhaust pipe 51 of the air-cooling module 5. In addition, sufficient installation space can be reserved below the lower plate 223 to facilitate the arrangement of the heating mechanism 3 and the air-cooling mechanism 52.

[0083] Continue as Figure 11 As shown, the exhaust box 523 also includes an air guide plate 5233, which is installed in the air box portion 5232 and divides the air box portion 5232 into a number of independently arranged exhaust spaces. The multiple air ducts 52321 on the air box portion 5232 are divided into a number of air duct groups, and the air duct groups are arranged in a one-to-one correspondence with the exhaust spaces. The air guide plate 5233 can separate the air box portion 5232 of the exhaust box 523 into independent exhaust spaces, and the air can be diverted to ensure that the exhaust efficiency of each exhaust space is almost the same, thereby ensuring that the air cooling effect of the corresponding heating barrel 31 is similar, avoiding the problem that some heating barrels 31 have poor air cooling effect and the handle embryo 100 in the heating barrel 31 locally overheats, while some heating barrels 31 have good air cooling effect and the heating efficiency of the handle embryo 100 in the heating barrel 31 is too low, which cannot meet the heating requirements, thereby reducing power consumption while improving air cooling efficiency.

[0084] Optionally, the air guide plate 5233 is V-shaped, with the tip of the air guide plate 5233 located at the end close to the connecting portion 5231 and the open end of the air guide plate 5233 located at the end away from the connecting portion 5231. The V-shaped air guide plate 5233 can isolate an independent area where ventilation is not required, thereby reducing the area within the bellows portion 5232 that requires ventilation, thereby ensuring the ventilation effect of the fan 521.

[0085] Figure 11 In the embodiment, there is one air guide plate 5233, which is located in the middle of the bellows portion 5232, dividing the bellows portion 5232 into two independent exhaust spaces and a space that does not require exhaust. Of the six air ducts 52321, three air ducts 52321 form a duct group, and each duct group is connected to one exhaust space. Of course, in other embodiments, the number of air guide plates 5233 can also be two, which will not be repeated here.

[0086] The working process of the handle blank 100 heating device provided in this embodiment is as follows:

[0087] 1) The handle blank 100 is conveyed by the blank feeding module 1; when the handle blank 100 is conveyed by the blank feeding mechanism 11 and the transition mechanism 12, the direction of the handle 102 of the handle blank 100 is in a disordered state. Under the action of the orienting component of the final orienting mechanism 13, the direction of the handle 102 of the handle blank 100 is adjusted to a unified direction.

[0088] 2) The transport mechanism 2 drives the embryo transfer mechanism 4, the heating mechanism 3, and the air cooling module 5 to rotate. During this process, the embryo insertion member 422 of the embryo transfer mechanism 4, in cooperation with the embryo entry section 43131 of the guide rail 431 and the reset member 432, is inserted into the handle embryo 100 conveyed by the orienting mechanism 13; as the transport plate 22 continues to rotate, the embryo insertion member 422, in cooperation with the barrel entry section 43116 of the guide rail 431 and the reset member 432, drives the handle embryo 100 to be inserted into the heating barrel 31 of the heating mechanism 3.

[0089] 3) The carrying mechanism 2 drives the embryo lifting and rotating mechanism 4, the heating mechanism 3 and the air cooling module 5 to continue rotating. During this process, the heating mechanism 3 and the air cooling module 5 are started at the same time. The heating barrel 31 of the heating mechanism 3 heats the handle embryo 100. The air cooling module 5 is used to suck the hot air in the heating barrel 31 to avoid local overheating of the handle embryo 100 in the heating barrel 31; the rotating drive component 45 of the embryo lifting and rotating mechanism 4 drives the embryo inserting part 422 to drive the handle embryo 100 to rotate, ensuring that the handle embryo 100 is heated evenly and avoiding local overheating.

[0090] 4) The transport mechanism 2 drives the preform lifting and transfer mechanism 4, the heating mechanism 3, and the air cooling module 5 to continue rotating. During this process, when the handle preform 100 is heated to a state suitable for blowing a bottle, the preform inserting member 422 of the preform lifting and transfer mechanism 4, in cooperation with the barrel-removing section 43112 of the guide rail 431, drives the handle preform 100 out of the heating barrel 31, and the preform removing robot 6 clamps the handle preform 100; as the transport plate 22 continues to rotate, the preform inserting member 422 is removed from the handle preform 100 by the action of the barrel-removing section 43121 of the guide rail 431; the preform removing robot 6 transfers the handle preform 100 into the bottle blowing machine for blowing a bottle.
