[0039] Working principle: when the closure processing of the headspace bottle is needed, the work personnel first stores the batch of headspace bottle closures in a stacked state in the plurality of storage barrels 11, and transports the headspace bottle which has not been subjected to the closure processing through the conveying line 2, so that a single headspace bottle is located below the first semicircular groove 63 and the second semicircular groove 65;

[0040] In the preparation process, the bottle caps in one of the storage barrels 11 fall down as a whole, the bottle cap at the bottom falls down through the discharging hole 51 to between the two arc-shaped pressing plates 56, at this time, the two air cylinders 55 are synchronously turned on to push the two arc-shaped pressing plates 56 to approach each other, so as to press the single bottle cap tightly;

[0041] When the capping process begins, the operator first starts the two air cylinders 55, causing the piston ends of the two air cylinders 55 to retract and then extend. First, the two arc-shaped pressing plates 56 move away from each other, and the bottle caps between the two arc-shaped pressing plates 56 fall onto the inclined surface 62 of the guide hopper 61, and at the same time, the bottle caps in the discharge hole 51 fall between the two arc-shaped pressing plates 56. With the extension of the two air cylinders 55, the two arc-shaped pressing plates 56 press the bottle caps tightly, ready for use.

[0042] The bottle caps that fall on the inclined surface 62 are moved along the inclined surface 62 towards the side of the conveying line 2 and fall into the open end of the empty bottle through the first semicircular groove 63 and the second semicircular groove 65. At this time, the conveying line 2 is started again, and the empty bottle and the bottle cap are conveyed to the bottom end of the capper 4 and vertically correspond to the pressing port of the capper 4.

[0043] At this time, the operator starts the second motor 89, and the drive shaft of the second motor 89 rotates the rotating rod 85, which transmits through the transmission wheel 86. The transmission belt 87 moves the gear set 88 on the transmission belt 87. When the gear set 88 engages with the first gear 8, the gear set 88 drives the first gear 8 to rotate, and the first gear 8 rotates the first transmission rod 79, which rotates the first rotating shaft 74 through the two first bevel gears 81. The first rotating shaft 74 rotates the first cam 75 by one hundred and eighty degrees, and the protruding part of the first cam 75 gradually contacts the upper surface of the U-shaped fixed frame 71. The first cam 75 gradually contacts the U-shaped fixed frame 71 in the process, and the capper 4 is lowered as a whole, and the pressing port of the capper 4 is sleeved on the bottle cap.

[0044] When the gear set 88 disengages from the first gear 8 and engages with the second gear 83, the gear set 88 drives the second gear 83 to rotate, and the second gear 83 rotates the telescopic rod 82, which rotates the second rotating shaft 77 through the two second bevel gears 84. The second rotating shaft 77 rotates the second cam 78, and the protruding part of the second cam 78 presses the handle of the capper 4. The pressing of the handle of the capper 4 causes the four pressing blocks of the pressing port of the capper 4 to turn inward, pressing the bottle cap on the empty bottle. With the re-engagement of the gear set 88 with the first gear 8 and the second gear 83, the first cam 75 and the second cam 78 rotate by one hundred and eighty degrees again, and reset to the initial state. The U-shaped fixed frame 71 and the capper 4 are automatically reset to the initial state due to the state of the spring rod 72, and the handle of the capper 4 is automatically turned over and reset for the next capping process of the empty bottle.

[0045] When the bottle caps in the single storage cylinder 11 are used up, the operator starts the first motor 54, the driving shaft of the first motor 54 rotates the rotating shaft 52, the rotating shaft 52 rotates the multiple storage cylinders 11 on the fixed disc 1 through the multiple connecting rods 53, so that another storage cylinder 11 full of bottle caps vertically corresponds to the discharging hole 51.

[0046] Obviously, various modifications and changes can be made to the present application without departing from the spirit and scope thereof.
