For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the circumstances. The following will describe the embodiments according to the overall structure of the present utility model.

[0029] As Figures 1-4 shown, the adjustable bottle inlet device of this embodiment includes: a base 1, a linear bottle feeding channel 2, a fixed stopper 3, an arc-shaped opening 4, an arc-shaped bottle inlet channel 5, gear teeth 6, a card slot 7, a second ball 8, a first ball 9, a connecting rod 10, a turntable 11, a disc 12, a first motor 13, a conveying frame 14, a second guardrail 15, a lid 16, a first guardrail 17, a support rod 18, a second motor 19, an arc-shaped stopper 20, a long strip chute 21, a screw 22 and a handle 23.

[0030] Continue to refer to Figures 1-4 , a conveying frame 14 is installed on the base 1, a linear bottle feeding channel 2 and an arc-shaped bottle inlet channel 5 are arranged on the conveying frame 14, a bottle inlet star wheel is installed on the conveying frame 14, the arc-shaped bottle inlet channel 5 can surround the bottle inlet star wheel, the bottle inlet star wheel includes a disc 12 and a plurality of gear teeth 6 evenly arranged on the outer circumference of the disc 12, and a detachable lid 16 is installed on the disc 12.

[0031] In this embodiment, one side of the end of the gear tooth 6 is hinged to the disc 12. When the lid 16 is opened, it can be seen that the turntable 11 is rotatably mounted on one side of the disc 12. One end of the connecting rod 10 is rotatably connected to the other side of the gear tooth 6, and the other end of the connecting rod 10 is rotatably connected to the edge of the turntable 11. The gear tooth 6 is provided with an arc-shaped opening 4. A clamping groove 7 is provided at the position of the disc 12 between two gear teeth 6. The arc-shaped opening 4 can form a bottle inlet area with the clamping groove 7. The clamping groove 7 is preferably an arc-shaped clamping groove. The first motor 13 is used to drive the turntable 11 to rotate forward and backward. The first motor 13 is preferably a servo motor. When the turntable 11 rotates forward, the gear tooth 6 in contact with the disc 12 is pushed out by the connecting rod 10, and the arc-shaped opening 4 can approach the clamping groove 7. At this time, the bottle inlet area decreases. When the turntable 11 rotates backward, the other side of the gear tooth 6 is pulled back toward the disc 12 by the connecting rod 10, and the arc-shaped opening 4 can move away from the clamping groove 7. At this time, the bottle inlet area increases. By adjusting the tooth pitch of the gear tooth 6, the effect of adjusting the size of the bottle inlet area is achieved. According to the bottles with different diameters, the size of the bottle inlet area is adjusted to ensure that the contact area between the gear tooth 6 and the arc-shaped opening 4 and the small-diameter bottle body will not decrease, preventing accidental tipping of the bottle body.

[0032] In this embodiment, a fixed stop 3 is installed at the outlet of the linear bottle feeding channel 2. The fixed stop 3 is preferably an arc-shaped stop. More specifically, first guardrails 17 are installed on both sides of the linear bottle feeding channel 2, and second guardrails 15 are installed on the outside of the arc-shaped bottle inlet channel 5. The fixed stop 3 is installed on the first guardrail 17 on the outside. The largest diameter bottle that the linear bottle feeding channel 2 can convey is called the large-diameter bottle, and the bottle with a body diameter smaller than the large-diameter bottle is called the small-diameter bottle. When the linear bottle feeding channel 2 conveys the large-diameter bottle, the fixed stop 3 can send the bottle into the bottle inlet area.

[0033] More specifically, the arc-shaped stop 20 is movably installed above the fixed stop 3. A long strip chute 21 corresponding to the arc-shaped stop 20 is opened on the first guardrail 17 on the outside. The arc-shaped stop 20 is installed in the long strip chute 21, and the arc-shaped stop 20 can move along the long strip chute 21. A screw rod 22 is installed in the long strip chute 21. One end of the screw rod 22 extends out of one end of the long strip chute 21 and is installed with a handle 23. The other end of the screw rod 22 is rotatably connected to the other end of the long strip chute 21. The arc-shaped stop 20 is threadedly connected to the screw rod 22. When the linear bottle feeding channel 2 feeds a small-diameter bottle, it is necessary to hold the handle 23 and rotate the screw rod 22 to drive the arc-shaped stop 20 to move along the long strip chute 21 until the position where the arc-shaped stop 20 is located can send the bottle into the bottle inlet area. The arc-shaped stop 20 and the bottle inlet star wheel with adjustable tooth pitch cooperate to feed the small-diameter bottle, improving the adaptability of the device.

[0034] Bottles with different diameters need to travel along the path formed by the fixed stopper 3 or the arc-shaped stopper 20. The other side of the previous tooth 6 cooperates with the fixed stopper 3 or the arc-shaped stopper 20 to hold the bottle, and then the fixed stopper 3 or the arc-shaped stopper 20 pushes the moving bottle into the next bottle inlet area. At this time, the bottle can smoothly enter the next bottle inlet area, achieving the smooth docking of the bottle and the bottle inlet star wheel.

[0035] In addition, the first ball 9 is installed on the outer periphery of the card slot 7 and the tooth 6, and the second ball 8 is installed on the outer first guardrail 17. The first ball 9 and the second ball 8 can rotate. When transitioning from bottle feeding to bottle inlet, the rotatable first ball 9 and the second ball 8 cooperate to prevent scratches on the bottle body during the transition stage from bottle feeding to bottle inlet, and can well protect the bottle body.

[0036] In this embodiment, the second motor 19 is fixed on the conveying frame 14. The second motor 19 is preferably a servo motor. There are two bottle inlet star wheels. The two bottle inlet star wheels are fixedly connected by a support rod 18. The center of the disk 12 located below is fixedly connected to the output end of the second motor 19, so that the second motor 19 drives the two bottle inlet star wheels to rotate synchronously. The bottle inlet star wheel located above can contact the upper half of the bottle body, and the bottle inlet star wheel located below can contact the lower half of the bottle body. By using the two bottle inlet star wheels to feed the bottles, the stability of the bottle inlet star wheel during bottle feeding is improved, and the situation of the bottle body tipping over during bottle feeding is greatly avoided.

[0037] In summary, in this embodiment, when conveying small-diameter bottles, by adjusting the tooth pitch of the tooth 6 and moving the arc-shaped stopper 20 to a position where it can push the bottle into the bottle inlet area, first, the arc-shaped stopper 20 cooperates with the tooth 6 with adjusted tooth pitch to hold the small-diameter bottle, and then the arc-shaped stopper 20 sends the bottle into the bottle inlet area, enabling the bottle to be smoothly docked with the bottle inlet star wheel, solving the problem of low safety of the bottle inlet star wheel after adjusting the tooth pitch of the tooth 6. The bottle body will not tip over due to the change in the tooth pitch of the tooth 6, improving the safety and adaptability of the device.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations are possible in light of the above teachings.
