One end of the rotating shaft 9 extends out of the conveyor box 8, and a rotating handle 11 is fixed to the end of the rotating shaft 9 extending out of the conveyor box 8.
[0027] By cooperating with the rotating shaft 9, guide plate 10, and rotating handle 11 mounted on the conveyor box 8, the rotating handle 11 can be rotated during the alignment process, thereby causing the rotating shaft 9 to rotate as a whole, which in turn causes the guide plate 10 to rotate as a whole. After being blocked by the guide plate 10, the bottle preforms are conveyed into different alignment slots. This ensures that the bottle preforms can stably enter different alignment slots during the operation and facilitates the stable operation of subsequent alignment work.
[0028] Reference Figure 1 , Figure 3 and Figure 4 As shown, an auxiliary aligning frame 12 is inclinedly arranged at one end of the conveyor frame 1 corresponding to the conveyor box 8. Both the conveyor frame 1 and the aligning frame 12 have protruding base frames 2 at their bottoms. The aligning frame 12 has a receiving cavity, within which aligning plates 13 are symmetrically slidably arranged. An aligning groove for auxiliary preform alignment is provided between the aligning frame 12 and the aligning plates 13. The aligning groove is funnel-shaped, and rotating rods 18 are rotatably arranged on both sides of the aligning groove. A rotating motor that drives the rotating rods 18 is installed on the aligning frame 12. A detachable rotating device is also provided on the aligning groove. The system is equipped with a counterweight baffle 14. Both ends of the alignment frame 12 are provided with adjustment slots. Both ends of the alignment plate 13 are provided with protrusions 131. The protrusions 131 are slidably disposed in the adjustment slots. An adjustment component 15 for assisting in adjusting the width of the alignment slots is installed in the adjustment slots.

The bidirectional lead screw 17 and the protrusions 131 are threadedly engaged. A motor 16 is installed on the alignment frame 12 to drive the bidirectional lead screw 17 to rotate and drive the adjustment motor 16.
[0029] By cooperating with the protrusions 131 and the adjustment components 15 on the alignment rack 12, the adjustment motors 16 at both ends of the alignment rack 12 are started. The adjustment motors 16 drive the bidirectional lead screw 17 to rotate as a whole. The bidirectional lead screw 17 and the protrusions 131 are threaded together, thereby causing the protrusions 131 to move as a whole. During the movement of the protrusions 131, the overall width of the alignment slot is adjusted, thereby adapting to the overall alignment requirements of bottle preforms of different sizes.

[0031] Working principle:
[0032] Before starting work, the adjusting motors 16 at both ends of the aligning rack 12 are started simultaneously. The adjusting motors 16 drive the bidirectional lead screw 17 to rotate as a whole. The bidirectional lead screw 17 is threadedly engaged with the protrusion 131, thereby causing the protrusion 131 to move as a whole. During the movement of the protrusion 131, the overall width of the aligning groove is adjusted to adapt to the overall aligning requirements of preforms of different sizes.
[0033] During operation, when it is necessary to arrange the preforms, the preforms are placed on top of the conveyor belt 5, and the servo motor 7 is started. The servo motor 7 drives the conveyor shaft 4 to rotate as a whole, and the conveyor shaft 4 drives the conveyor belt 5 to rotate as a whole, thereby moving the conveyor belt 5 as a whole. During the movement of the conveyor belt 5, the preforms are driven to fall into the arranging groove of the arranging rack 12. The bottle neck is located at the top of the arranging groove, and the preforms below the bottle neck fall to the bottom of the arranging groove. The counterweight baffle 14 can block the stacked preforms and make the preforms stably arranged as a whole.
[0034] By rotating the handle 11, the rotating shaft 9 is rotated as a whole, which in turn causes the guide plate 10 to rotate as a whole. After being blocked by the guide plate 10, the preform is conveyed into different alignment slots.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
