The carrying mechanism 2 serves as a mounting structure of the heating mechanism 3 and the lifting and turning blank mechanism 4, and can drive the heating mechanism 3 and the lifting and turning blank mechanism 4 to rotate synchronously. The lifting and turning blank mechanism 4 is used for receiving the handle blank 100 conveyed by the blank feeding module 1, and turning the handle blank 100 to the heating mechanism 3 for heating.

[0059] Figure 4 The structure schematic diagram of the carrying mechanism 2 provided by the embodiment is shown. Figure 4 As shown, the carrying mechanism 2 includes a rack 21, a carrying disc 22 and a carrying disc driving assembly 23, the carrying disc 22 is rotatably installed on the rack 21, and the carrying disc driving assembly 23 is used for driving the carrying disc 22 to rotate relative to the rack 21.

[0060] Exemplarily, the total exhaust pipe 51 of the air cooling module 5 is arranged at the middle position of the lower disc body 223 of the carrying disc 22, and the center line of the total exhaust pipe 51 coincides with the center line of the lower disc body 223.

[0061] Figure 5 The structure schematic diagram of the lifting and turning blank mechanism 4 installed on the carrying disc 22 provided by the embodiment is shown. Figure 6 The partial schematic diagram of the lifting and turning blank mechanism 4 installed on the carrying disc 22 provided by the embodiment is shown. Figures 5-6As shown, the lifting and turning embryo mechanism 4 comprises a support 41 fixed on the carrier disc 22, an embryo inserting assembly 42, and a lifting driving assembly 43. The embryo inserting assembly 42 comprises a lifting seat 421 slidably mounted on the support 41 and an embryo inserting piece 422 mounted on the lifting seat 421 and above the warming barrel 31. The lifting driving assembly 43 is configured to drive the lifting seat 421 to lift or lower relative to the support 41, so that the embryo inserting piece 422 can be inserted into the handle embryo 100 on the embryo mold group 1 and the embryo body 101 of the handle embryo 100 can be inserted into the warming barrel 31. Exemplarily, the support 41 is fixed on the upper disc body 221 of the carrier disc 22.

[0062] The lifting and turning embryo mechanism 4 further comprises a guide assembly 44 comprising a sliding rail 441 fixed on the support 41 in the vertical direction and a sliding block 442 configured to mount the lifting seat 421. Through the guide assembly 44, the lifting seat 421 can be stably lifted or lowered along the sliding rail 441.

[0063] The lifting driving assembly 43 comprises a guide rail 431 and a reset piece 432. The guide rail 431 comprises an ascending section and a descending section. The lifting seat 421 can be lifted along the ascending section of the guide rail 431 and lowered along the descending section of the guide rail 431 under the action of the reset piece 432. The lifting of the lifting seat 421 can drive the lifting of the embryo inserting piece 422. During the lowering of the embryo inserting piece 422, the embryo inserting piece 422 is inserted into the handle embryo 100 and the handle embryo 100 is inserted into the warming barrel 31. During the lifting of the embryo inserting piece 422, the embryo inserting piece 422 drives the handle embryo 100 to be separated from the warming barrel 31 and the embryo inserting piece 422 is separated from the handle embryo 100.

[0064] Optionally, the reset piece 432 is a linear driver mounted on the support 41, and the output end of the reset piece 432 is connected with the lifting seat 421. Exemplarily, the reset piece 432 can be a linear cylinder, a linear hydraulic cylinder or a linear motor. Preferably, when the reset piece 432 is a linear driver, the output end of the reset piece 432 is hingedly connected with the lifting seat 421, which can be through floating connection, hinge connection or spherical hinge connection. Of course, in other embodiments, the reset piece 432 can also be a high-strength reset spring. When the lifting seat 421 is lifted, the spring is in a stretched state, 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.

[0065] In order to avoid the embryo inserting piece 422 from being infinitely lowered under the action of the reset piece 432, the upper end of the embryo inserting piece 422 is provided with a limiting plate for limiting the lowering position of the embryo inserting piece 422.

[0066] Preferably, the plugger assembly 42 further comprises a follower wheel 423 rotatably mounted on the lifting seat 421, and a wheel surface of the follower wheel 423 is capable of abutting against the lifting driver, so as to ensure that the lifting seat 421 can be stably lifted along the guide rail 431, and meanwhile, the friction between the lifting seat 421 and the guide rail 431 is reduced.

[0067] Figure 7 A partial sectional view of the lifting and turning mechanism 4 is shown. As shown in the figure, Figure 7 In combination Figure 6 As shown, the lifting and turning mechanism 4 further comprises a rotating driving assembly 45, and the plugger 422 is rotatably mounted on the lifting seat 421, and the rotating driving assembly 45 is used to drive the plugger 422 to rotate, so as to ensure that the handle blank 100 is uniformly heated during the heating process, and local overheating is avoided.

[0068] The plugger 422 comprises a plugger head 4222 and a lifting and rotating shaft 4221 connected with each other, and the lifting and rotating shaft 4221 is rotatably connected with the lifting seat 421 through a bearing. Exemplarily, the plugger head 4222 and the lifting and rotating shaft 4221 are connected through a clamping groove or a key groove, so as to realize synchronous rotation of the plugger head 4222 and the lifting and rotating shaft 4221. The plugger head 4222 can be selected from conventional plugger heads in the prior art, for example, the plugger head comprises a first piece and a second piece, the second piece is sleeved on the first piece, an O-shaped rubber ring is arranged between the second piece and the first piece, the second piece is used to be inserted into the bottle mouth of the bottle blank, the second piece is an expansion piece, and the O-shaped rubber ring is elastically deformed, so as to realize that the second piece can be smoothly inserted into and expanded in the bottle mouth of the bottle blank. Here, no longer exemplified one by one.

[0069] Alternatively, the rotating driving assembly 45 comprises a rotating driver 451, an input gear 452, an output gear 453 and a sliding sleeve 454, the rotating driver 451 is mounted on the support 41 and is used to drive the input gear 452 to rotate, the output gear 453 is engaged with the input gear 452, the sliding sleeve 454 is in transmission connection with the output gear 453, the lifting and rotating shaft 4221 of the plugger 422 is slidably arranged in the sliding sleeve 454 and can rotate with the sliding sleeve 454 and can be lifted and lowered relative to the sliding sleeve 454. It is worth mentioning that the sliding sleeve 454 is in transmission connection with the output gear 453, which can be fixed in the output gear 453 or can be connected with the output gear 453 through a key groove, as long as the sliding sleeve 454 can rotate with the output gear 453.

[0070] Exemplarily, the lifting rotating shaft 4221 is matched with the sliding sleeve 454 through a straight key groove or a plane transmission, when the lifting seat 421 drives the insertion embryo part 422 to lift, the insertion embryo part 422 can lift relative to the sliding sleeve 454 and the output gear 453, so as to realize the insertion embryo head 4222 of the insertion embryo part 422 to enter the embryo, enter the barrel, get out of the barrel and get out of the embryo; when the output gear 453 drives the sliding sleeve 454 to rotate, the lifting rotating shaft 4221 can also drive the insertion embryo head 4222 to rotate, so as to realize the rotation of the handle embryo 100 with the insertion embryo head 4222, and make the handle embryo 100 heat evenly. In addition, the lifting rotating shaft 4221 is coaxially arranged with the insertion embryo head 4222, the lifting action and the rotating action are concentrated on the same axis, the structure is compact, and the lifting action and the rotating action are independent and have no interference between each other.

[0071] Exemplarily, the rotating driver 451 can be selected as an electric motor with an encoder, through program control, the rotating driver 451 drives the lifting rotating shaft 4221 to drive the insertion embryo head 4222 to rotate in the warming barrel 31 in forward and reverse directions or variable speed, so as to ensure that the handle embryo 100 is heated evenly. Through the encoder, different embryo rotating requirements can be adapted. In addition, the lifting and rotating embryo mechanism 4 can accurately position the handle 102 direction of the handle embryo 100 in the process of warming the handle embryo 100 in the warming barrel 31, so as to avoid heating the handle 102. Each warming barrel 31 is connected with the air cooling mechanism 52, and the air cooling mechanism 52 is used for air extraction in the warming barrel 31, so as to avoid local overheating of the handle embryo 100.

[0072] Continuing as shown in Figure 7 The lifting rotating shaft 4221 is rotatably connected with the lifting seat 421 through a bearing, the lifting rotating shaft 4221 is fixedly connected with the bearing through a circlip, and the lifting seat 421 drives the lifting rotating shaft 4221 to synchronously lift when the lifting seat 421 lifts.

[0073] Figure 8 A structure schematic view of the guide rail 431 provided by the embodiment is shown. As Figure 8As shown, the guide rail 431 includes, in sequence along the rotation direction of the carrying disc 22, a bucket removing section 43112, an embryo removing section 43121, an embryo entering section 43131 and a bucket entering section 43116, the bucket removing section 43112 and the embryo removing section 43121 are arc sections rising along the rotation direction of the carrying disc 22, and the embryo entering section 43131 and the bucket entering section 43116 are arc sections falling along the rotation direction of the carrying disc 22, and the lifting seat 421 can be lifted along the guide rail 431. Since the lifting seat 421 is in sliding fit with the slide rail 441 on the support 41 through the sliding block 442, when the carrying disc 22 rotates, the lifting seat 421 can be lifted along the slide rail 441 under the action of the bucket removing section 43112 and the embryo removing section 43121 of the guide rail 431; when the carrying disc 22 continues to rotate, the lifting seat 421 can be lowered along the embryo entering section 43131 and the bucket entering section 43116 of the guide rail 431 under the driving of the reset member 432.

[0074] The lifting node of the lifting movement of the embryo inserting member 422 of the lifting and embryo rotating mechanism 4 needs to be accurately positioned and matched with the handle embryo 100 conveyed by the embryo feeding module 1 and the clamping end of the embryo taking manipulator 6, so as to accurately insert the handle embryo 100 and rotate into the warming bucket 31 or separate the handle embryo 100 so as to take away the handle embryo 100 by the embryo taking manipulator 6. Specifically, along the rotation direction of the carrying disc 22, the starting end of the embryo removing section 43121 of the guide rail 431 is aligned with the clamping end of the embryo taking manipulator 6, the clamping end of the embryo taking manipulator 6 clamps the handle embryo 100 first, then when the lifting seat 421 rises along the embryo removing section 43121, the embryo inserting head 4222 separates from the handle embryo 100, and the embryo taking manipulator 6 transfers the handle embryo 100 to the bottle blowing machine; the end of the embryo entering section 43131 of the guide rail 431 is aligned with the handle embryo 100 conveyed by the embryo feeding module 1, and when the lifting seat 421 descends along the embryo entering section 43131, the embryo inserting head 4222 on the lifting seat 421 can be inserted into the handle embryo 100 conveyed by the embryo feeding module 1, and the embryo inserting head 4222 receives the handle embryo 100.

[0075] When the whole bottle embryo warming device is assembled, due to installation errors or machining errors of parts, the guide rail 431 may not be accurately aligned with the embryo feeding module 1 and the embryo taking manipulator 6, at this time, whether adjusting the position of the whole guide rail 431 or adjusting the position of the embryo feeding module 1 and the embryo taking manipulator 6 is not convenient to operate, and it is easy to be inaccurate once, and needs to be adjusted and aligned repeatedly, which not only increases the labor of workers, but also is low in operation efficiency.

[0076] To solve the above problems, the embryo removing section 43121 and the embryo entering section 43131 of the guide rail 431 are designed to be position-adjustable. By adjusting the positions of the embryo removing section 43121 and / or the embryo entering section 43131, the alignment of the embryo removing section 43121 with the embryo taking manipulator 6 and the alignment of the embryo entering section 43131 with the embryo feeding module 1 are realized. This not only facilitates adjustment, but also has high adjustment efficiency and facilitates repeated adjustment.

[0079] Furthermore, the height difference between the second horizontal segment 43113 and the first horizontal segment 43111 is greater than the height difference between the third horizontal segment 43114 and the second horizontal segment 43113, meaning the height span of the unloading segment 43112 is greater than the height span of the unloading segment 43121. The height difference between the fifth horizontal segment 43117 and the fourth horizontal segment 43115 is greater than the height difference between the fourth horizontal segment 43115 and the third horizontal segment 43114, meaning the height span of the loading segment 43116 is greater than the height span of the loading segment 43131.

The heating barrel 31 is mounted on the mounting base 32, and the heating barrel 31 and the blank insert 422 are coaxially arranged. In other embodiments, the heating mechanism 3 can be directly mounted on the transport tray 22, as long as the blank insert 422 of the lifting and rotating blank mechanism 4 can insert the handle blank 100 into the heating barrel 31 of the heating mechanism 3.

[0081] Optionally, the warming barrel 31 comprises a warming shell and heating lamps, the heating lamps are partially accommodated in the warming shell, and the plurality of heating lamps are arranged at intervals along the length direction of the warming shell. The embryo body 101 of the handle embryo 100 is inserted into the warming shell and located in the middle of the heating lamps, and the embryo body 101 of the handle embryo 100 is heated by the heating lamps.

[0082] The warming shell is a shell structure penetrating from top to bottom, the handle embryo 100 is inserted into the warming shell under the action of the embryo inserting member 422, and the air cooling module 5 is connected below the warming shell, air in the warming shell is sucked from below the warming shell, so as to avoid that the temperature in the warming shell is too high locally.

[0083] Continuing as shown in Figure 10 , the air cooling mechanism 52 comprises a fan 521, an exhaust pipe 522 and an air suction box 523, one end of the exhaust pipe 522 is connected to the air outlet of the fan 521, and the other end of the exhaust pipe 522 is connected to the general exhaust pipe 51; the air suction box 523 is connected to the air inlet of the fan 521, and a plurality of air pipes 52321 are arranged on the air suction box 523, the warming barrel 31 is installed on the air pipe 52321 and communicates with the air pipe 52321. Figure 10 In this embodiment, one air cooling mechanism 52 comprises six air pipes 52321, and each air pipe 52321 is connected to one warming barrel 31. Of course, in other embodiments, any number of air pipes 52321 can also be arranged on the air suction box 523 of one air cooling mechanism 52, and the number can be set according to the size of the air suction box 523 and the power of the fan 521, which is not limited herein. In this way, the number of fans 521 can be reduced, the cost of the equipment can be reduced, and the processing, manufacturing and installation positioning of the air cooling mechanism 52 can be facilitated.

[0084] Exemplarily, the warming barrel 31 is connected to the air pipe 52321 through a corrugated pipe 524. The connection through the corrugated pipe 524 can compensate for the processing or installation error and facilitate the installation operation.

The air box portion 5232 of the air suction box 523 can be separated into independent air suction spaces by the baffle 5233, and the air can be divided, thereby ensuring that the air suction efficiency of each air suction space is nearly the same, ensuring that the air cooling effect on the corresponding warming barrel 31 is similar, avoiding the problem that the air cooling effect of part of the warming barrel 31 is poor, and the handle blank 100 in the warming barrel 31 is locally overheated, while the air cooling effect of part of the warming barrel 31 is good, and the handle blank 100 in the warming barrel 31 is heated at a low efficiency, which cannot meet the heating demand, reduces power consumption, and improves air cooling efficiency.

Every three air pipes 52321 in the six air pipes 52321 form an air pipe group, and each air pipe group communicates with an air suction space. Of course, in other embodiments, the number of baffles 5233 can also be 2, which will not be described here.
