The clamping plate 912 and the anti-slip pad 913 are both arc-shaped to improve the clamping effect on the plastic bottle.

[0042] Embodiment Two:

[0043] Based on the above-mentioned first embodiment, when it is necessary to tighten bottle caps with different diameters, it is first necessary to replace the rotating seat so that the replaced engaging groove 20 can be adapted to the bottle cap. Therefore, the following structure is set up.

[0044] Refer to Figure 2 and Figure 5 , a slot 16 is opened at the bottom end of the drive shaft 15, a socket 17 is inserted into the inside of the slot 16, and a locking bolt 18 extending into the inside of the socket 17 is installed on one side of the drive shaft 15.

The setting of the socket 17 facilitates the installation of the rotating seat 19, and the setting of the engaging groove 20 can engage the bottle cap so that the bottle cap can be driven to rotate when the rotating seat 19 rotates. The rotating seat 19 is detachably connected to the drive shaft 15 through the socket 17. When disassembling the rotating seat 19, only need to screw the locking bolt 18 out of the socket 17, and then the rotating seat 19 can be removed, so that the rotating seat 19 and the engaging groove 20 can be replaced.

[0045] Embodiment Three:

[0046] Based on the above-mentioned first embodiment, in order to improve the stability of the turntable 10 when rotating, the following structure is set up.

[0047] Refer to Figures 1-3 , support columns 6 are provided on both sides of the top of the base 1. A ball groove 7 is opened at the top end of the support column 6, and balls 8 are arranged inside the ball groove 7. The top of the balls 8 is in contact with the bottom of the turntable 10 so that the balls 8 can roll inside the ball groove 7, and the balls 8 can support the turntable 10 to improve the stability of the turntable 10 when rotating.

[0048] The working principle of the present utility model is as follows: First, the staff can install the device and connect it to the power supply. Then, place the plastic bottle into the placing cylinder 21 and position the plastic bottle between the two clamping plates 912. Next, start the motor 2. When the motor 2 works, it can drive the driving gear 5 to rotate, then drive the driven gear 4 to rotate, and drive the movable shaft 3 to rotate. The movable shaft 3 drives the turntable 10 to rotate, the turntable 10 drives the placing cylinder 21 to rotate, and then drives the plastic bottle to rotate. When the plastic bottle rotates to directly below the rotating seat 19, the motor 2 stops and the hydraulic cylinder 12 is started simultaneously. When the hydraulic cylinder 12 works, the piston rod can extend, thereby driving the lifting frame 13 to move downward, then driving the rotating seat 19 to move downward. At the same time, the lifting frame 13 drives the side plate 901 to move downward, the side plate 901 drives the threaded rod 902 and the pressing block 903 to move downward, the pressing block 903 pushes the movable ring 904 to move downward, the movable ring 904 pushes the push plate 908 to rotate, the push plate 908 pushes the sliding seat 909 to move, the sliding seat 909 drives the movable rod 911 to move, and then drives the clamping plate 912 and the anti-slip pad 913 to move, so that the anti-slip pad 913 can fit against the outer wall of the plastic bottle, thereby achieving the purpose of clamping and limiting the plastic bottle;

[0049] After the bottle cap is moved into the engaging groove 20, close the hydraulic cylinder 12 and start the driving motor 14. When the driving motor 14 works, it can drive the driving shaft 15 to rotate, then drive the rotating seat 19 to rotate. The rotating seat 19 can drive the engaging groove 20 to rotate, and then drive the bottle cap to rotate, so as to tighten the bottle cap on the plastic bottle. After tightening, turn off the driving motor 14 and start the hydraulic cylinder 12, so that the piston rod contracts, thereby driving the lifting frame 13 and the rotating seat 19 to move upward. At the same time, drive the threaded rod 902 and the pressing block 903 to move upward. The pressing block 903 no longer presses on the movable ring 904, and the spring 907 stretches and then pushes the slider 905 to move upward and reset, then drives the movable ring 904 to move upward and reset, and drives the clamping plate 912 to move back, so that the clamping plate 912 no longer clamps the plastic bottle; Then drive the motor 2, so that the turntable 10 continues to rotate. When the next plastic bottle to be capped rotates to directly below the rotating seat 19, the motor 2 stops and the hydraulic cylinder 12 is started, and repeat the above steps to tighten the bottle cap on the plastic bottle. During the process of tightening the bottle cap, the staff can take out the plastic bottle with the tightened bottle cap from the placing cylinder, and then put the plastic bottle to be capped into the placing cylinder 21;

[0050] When it is necessary to adjust the distance between the pressing block 903 and the movable ring 904 to adapt to plastic bottles of different heights or diameters, the staff only needs to rotate the threaded rod 902, so that the threaded rod 902 moves and drives the pressing block 903 to move, thereby adjusting the height of the pressing block 903. By adjusting the height of the pressing block 903, the downward movement distance of the movable ring 904 can be adjusted, and the movement distance of the clamping plate 912 can also be adjusted.
