The rotating shaft 25 is vertically arranged, and the top of the rotating shaft 25 is connected with the gear set. When the rotating front shaft 24 rotates, the rotating motion is transmitted to the rotating shaft 25 through the gear set. Preferably, the rotating front shaft 24 drives the rotating shaft 25 to rotate.

[0054] Preferably, the gear set comprises two meshing conical gears 26, which are assembled into the internal cavity of the turnover body 21.

It should be noted that the pin penetrates the elongated slot hole. Through the above arrangement, the lifting pin disc 2a and the pressing pin 28 are coupled and can move synchronously along the axis direction of the rotating shaft 25, and the moving range is limited by the elongated slot hole.

[0060] The pressing pin 28, the pressing cap 29 and the lifting pin disc 2a form a rigid connection body, the rotating shaft 25 and the clamping neck 27 form a rigid connection body, and the two connection bodies are combined into a whole, which is rigidly connected in the circumferential direction and can only rotate together, and can move relatively in the axial direction, and the moving range is limited by the elongated slot hole of the rotating shaft 25.

[0061] Optionally, the rotating shaft 25 is internally provided with a pressing spring 2b, which is sleeved on the upper part of the pressing pin 28 and is in a compressed state, that is, the pressing spring 2b always has a tendency to press the pressing pin 28 downward, and similarly, the pressing cap 29 and the lifting pin disc 2a are always pressed downward.

[0062] Through the above arrangement, the bottle neck of the infusion bottle 100 is clamped by the clamping neck 27, and the bottle opening of the infusion bottle 100 is pressed by the pressing cap 29. When the turnover device 2 is driven by the main rotating disc 13 to rotate around the main shaft 12, the rotating driving wheel 23 is always attached to the turnover track 31, and as the position of the turnover track 31 changes, the combination of the turnover device 2 and the infusion bottle 100 is turned up and down around the axis of the turnover wheel shaft 22, and at the same time, the rotating driving wheel 23 rolls along the turnover track 31, thereby driving the infusion bottle 100 to rotate around its own axis.

[0063] It should be noted that the angle of the turnover device 2 turning around the axis of the turnover wheel shaft 22 is determined by the turnover track 31.

[0064] The turnover device 2 further comprises a lifting pin mechanism, which comprises a lifting pin roller 2c, a lifting pin shaft 2d and a lifting pin roller 2e. The lifting pin shaft 2d is assembled in another assembly hole at the bottom of the turnover body 21, and the top of the lifting pin shaft 2d is movably inserted into the assembly hole. A longitudinal hole communicating with the inside of the turnover body 21 is provided on one side of the turnover body 21 in the vertical direction, one end of the lifting pin roller 2c extends into the longitudinal hole and is connected to the side wall of the lifting pin shaft 2d, and the lifting pin roller 2e is connected to the bottom of the lifting pin shaft 2d and rotates to attach to the bottom of the lifting pin disc 2a. Preferably, one end of the lifting pin roller 2e is connected to the middle region of the lifting pin shaft 2d.

[0065] Optionally, the inside of the turnover body 21 is equipped with a reset spring 2f, which is sleeved on the upper part of the ejector shaft 2d and is in a compressed state, that is, the reset spring 2f always has a tendency to press down the ejector shaft 2d, and the ejector roller 2e is also always pressed down by the ejector shaft 2d.

[0066] When the ejector roller 2c is lifted, the ejector roller 2e is lifted by the ejector shaft 2d, so that the ejector disc 2a is lifted, and the compression pin 28 and the compression cap 29 are lifted synchronously; when the ejector roller 2c is no longer lifted, the ejector shaft is lifted downward under the action of its own gravity and the reset spring 2f, the ejector roller 2e no longer lifts the ejector disc 2a, and the ejector disc 2a is lifted downward under the action of the compression spring 2b, and the compression pin 28 and the compression cap 29 are lifted downward.

[0067] The ejector mechanism further comprises a limiting seat 2g and a limiting roller 2h, the limiting seat 2g is arranged between the self-rotation driving wheel 23 and the turnover body 21, two through holes are arranged on the limiting seat 2g in intervals, the self-rotation front shaft 24 is fastened in one of the through holes of the limiting seat 2g, and the limiting roller 2h is fastened in the other through hole of the limiting seat 2g. The axis of the limiting roller 2h is parallel to the axis of the self-rotation driving wheel 23, and the outer end of the limiting roller 2h is aligned with the outer end of the self-rotation driving wheel 23. The turnover track 31 is clamped between the self-rotation driving wheel 23 and the limiting roller 2h, and the limiting roller 2h rolls along the turnover track 31 when the rotating disc 13 rotates. Appropriately, the turnover track 31 is made of a round steel with a diameter equal to the net distance between the self-rotation driving wheel 23 and the limiting roller 2h.

[0068] The limiting device further comprises an ejector boss 33 for cooperating with the turnover device 2 to release the infusion bottle 100. The ejector boss 33 is installed on the rack 1 and located below the rotating disc 13.

The ejector boss 33 is provided with a circular-arc boss, one end of the boss is a bevel section, and the rear of the boss is a flat section.

[0069] It should be noted that the ejector boss 33 is located directly above the discharging device 5, when each turnover device 2 revolves to the ejector boss 33, the ejector roller 2c on the turnover device 2 is lifted upward by the bevel section of the ejector boss 33 and is kept in place at the flat section, and when the ejector roller 2c rolls over the flat section, it loses the lifting force and returns to the original position.

[0070] With the above arrangement, when the bottle diameter card of the infusion bottle 100 is clamped in the card neck 27, the lifting pin roller 2c loses the instant lifting force, and the lifting pin shaft 2d and the pressing pin 28 move downward quickly, pressing the pressing cap 29 at the lower end of the pressing pin 28 against the bottle mouth of the infusion bottle 100, thereby clamping the infusion bottle 100 and the turnover device 2 into an integrated body; when the combined body of the turnover device 2 and the infusion bottle 100 is driven by the turntable 13 to revolve nearly a circle, the lifting pin roller 2c rolls to the lifting pin boss 33 and is lifted by the lifting pin boss 33, driving the pressing cap 29 to lift away from the bottle mouth of the infusion bottle 100, so that the infusion bottle 100 is separated from the turnover device 2, thereby releasing the infusion bottle 100.

[0071] The automatic defoaming machine further comprises a feeding device 4, which is connected to the conveying line, and is configured to push the infusion bottles 100 on the conveying line into the card neck 27 slots of the card neck 27 one by one.

Meanwhile, the ratio of the diameter of the circumference where the center of the neck clamping groove 27 is located to the diameter of the circumference where the groove centers of the second bottle clamping groove 51-1 are located is 3:1.

[0081] Preferably, the end of the inclined section of the lifting boss 33 away from the flat section is directly above the tangent point of the circumferences where the center of the neck clamping groove 27 and the groove centers of the second bottle clamping groove 51-1 are located.
