In another embodiment of the present invention, as shown in fig. 10, a protective cover 12 is further installed on the longitudinal support frame 1, and the protective cover 12 is disposed to cover the driven gear 11. The protective cover plate 12 is used for protecting the conveying chain 31, and dust is prevented from falling into the conveying chain 31 and damaging the conveying chain 31. In addition, when the bottle blank 14 moves to the area covered by the protective cover 12 along with the conveying chain 31, the bottle blank 14 gradually turns from the bottle opening to the upper side to be in a state of the bottle opening being horizontal, and at this time, the protective cover 12 has an effect of protecting the bottle blank 14 from falling. Specifically, if the bottle blank is loosened in the clamping groove 33, but the protective cover 12 covers the driven gear 11, even if the bottle blank 14 is loosened in the area covered by the protective cover 12, the bottle blank 14 will contact with the inner surface of the protective cover 12, and due to the blockage of the protective cover 12, the bottle blank 14 will move forward along with the transmission of the conveying chain 31 until the bottle blank moves to a position outside the area covered by the protective cover 12, and at this time, the bottle blank 14 also has a downward bottle mouth and can freely fall onto a follower fixture.
In another embodiment of the present invention, as shown in fig. 13, a bottle blank holding rod 13 is disposed on one side of the protective cover 12 close to the screw rod 43, the bottle blank holding rod 13 extends to the end of the screw rod 43, and the bottle blank holding rod 13 is disposed parallel to the conveying chain 31. The bottle embryo clamping rod 13 plays a guiding role in the conveying process of the bottle embryo 14. The bottle blank 14 can be ensured to enter the protective cover plate 12 smoothly.
The working principle of the embryo feeding mechanism 802 of the invention is as follows:
firstly, the bottle blank 14 is upward at the mouth, firstly slides downward along the blank guide frame 2 under the action of gravity, and simultaneously the screw rod 43 is driven by the second driving assembly 5 to rotate, so that the bottle blank 14 gradually contacts with the screw rod 43 and the spiral groove 42 of the screw rod 43, and moves forward under the pushing of the screw rod 43. The bottle embryo 14 moves forward under the pushing of the screw rod 43 and moves gradually toward the bottle embryo clamping block 32 close to the conveying chain 31, and when the bottle embryo 14 moves to the end of the screw rod 43, the bottle embryo 14 is just clamped into the clamping groove 33 of the bottle embryo clamping block 32 under the pushing of the screw rod 43.
Meanwhile, in the process that the screw rod 43 pushes the bottle blanks 14 to move forwards, the conveying chain 31 is driven to rotate by the first driving assembly 34, and the distance between the conveying chain 31 and the screw rod 43 is synchronously shortened while the conveying chain and the screw rod synchronously move forwards. After the bottle preform 14 is transferred to the bottle preform clamping block 32, the bottle preform 14 moves forward under the driving of the conveying chain 31, the bottle preform 14 gradually changes from a bottle opening upward to a bottle opening horizontal, and finally, when the bottle preform 14 is conveyed to the bottom end of the protective cover plate 12, the bottle preform 14 just faces downward, and at this time, the bottle preform 14 falls onto the chain conveying mechanism 803 in a free-falling manner.
The pitch of the conveying chain 20 of the chain conveying mechanism 803 is the same as the pitch of the conveying chain 31 of the invention, so that the conveying chain 31 of the invention and the chain conveying mechanism 803 realize synchronous motion during conveying, thereby realizing that the bottle blanks 14 are sequentially transited from the blank guide frame 2 to the conveying chain and then conveyed to the chain conveying mechanism 803.
As shown in fig. 1 to 2 and 4 to 21, the chain transmission mechanism includes a chain support 10, a transmission chain 20, and a driving source 30.

The conveying chain 20 is disposed in a curved shape, and a plurality of branch chains 40 are formed after the bending, and the branch chains 40 are disposed in parallel.
The chain transmission mechanism 803 of the present invention, on one hand, greatly saves the longitudinal space occupied by the transmission mechanism compared with a straight transmission mechanism by arranging the transmission chain 20 in a bending way; on the other hand, the branch chains 40 are arranged in parallel, so that the volume of the whole chain conveying mechanism 803 is further saved, the volume proportion of the chain conveying mechanism 803 in the blow molding machine is small, the transportation is convenient, the production cost is reduced, and the practicability is high.

Specifically, the two pivot shafts 604 are rotatably connected to the transverse fixing block. The fixing portion 603 is matched with a bottle blank to be blown, and when the bottle blank is fixed, a bottle opening of the bottle blank is inserted into the fixing portion 603, so that the blow molding is convenient and rapid.
Further, a guiding chain wheel 606 is further disposed at the bottom of the pivot shaft 604. The chain support 10 is provided with a guide chain 607 matched with the guide chain wheel, so that the guide chain wheel 606 of the conveying chain 20 can transmit along the guide chain 607. Specifically, when the guide chain wheel 606 is driven along the guide chain 607, the guide chain wheel 606 rotates to drive the pivot shaft 604 to rotate, the pivot shaft 604 drives the fixing part 605 at the top of the pivot shaft to rotate, and the bottle blank is fixed on the fixing part 605, so that the guide chain wheel 606 automatically transmits through the guide chain 607 and drives the bottle blank on the fixing part 605 to rotate, so that the bottle blank is heated in multiple directions when being conveyed, the heating is uniform, the bottle blank is heated by matching with an external heating device (not shown), and the conveying effect and the heating effect are both excellent.
In another embodiment of the present invention, as shown in fig. 14-15, two pulleys 701 are symmetrically disposed on two sides of the pivot block 70, and the two pulleys 701 are slidably mounted on the chain supporting frame 10.

When the driving source 30 works, the driving motor 301 rotates to drive the driving gear 302 to rotate, and the driving gear 302 drives the transmission module 60 to move, so as to drive the transmission chain 20 to move.
In another embodiment of the present invention, as shown in fig. 14 and 17, the chain transmission mechanism 803 further includes a plurality of auxiliary transmission gears 80, and each of the auxiliary transmission gears 80 is in transmission connection with any one of the branch chains 40.

In actual production, in order to increase the transmission speed, a power device may be added to the auxiliary transmission gear 80, and the power device is added to drive the auxiliary transmission gear 80, so as to increase the transmission speed of the branch chain 40. In addition, the auxiliary transmission gear 80 is also used for steering the conveying chain, and the conveying chain is bent by arranging the auxiliary transmission gear 80 to form a plurality of branch chains, so that the whole volume of the chain conveying mechanism 803 is reduced.
The working principle of the chain transmission mechanism 803 of the present invention is as follows:
when the chain transmission mechanism 803 is used for transmitting bottle blanks, the bottle blanks are fixed on the fixing portion 603, then the driving motor 301 drives the driving gear 602 to rotate, the driving gear 302 drives the transmission chain 20 to rotate, at the moment, the driving source 30 drives the whole chain which is bent for multiple times to transmit the bottle blanks, a plurality of bottle blanks can be transmitted simultaneously, the space is saved, and the bottle blank transmission efficiency is improved. Specifically, when the conveying chain 20 moves, the driving gear 302 drives the transmission module 60 to transmit through the driving teeth 303 during the rotation process. For the transmission module 60 located at the transfer part 50 or the auxiliary transmission gear 302, the adjacent transmission module 60 realizes turning through the pivot joint block 70, and in particular, when turning, the connection part 605 of the transmission module 60 and the pivot joint block 70 rotate, that is, the pivot joint block 70 rotates with the pivot joint shaft 604 as a rotation shaft, so as to change a fixed angle between the pivot joint block 70 and the transmission module 60, thereby realizing turning transmission at the transfer part 50 or the auxiliary transmission gear 80.
