The device is provided with six connecting brackets 7, which can enable the device to perform multi-station capping operations on the bottles on the upper ends of six assembly lines at the same time, thereby improving the use efficiency of the device, ensuring the rapid progress of production, and making the device more convenient to use;

[0026] The cover control pipe 16 is arranged inside the bottom plate 12. The lower end of the cover control pipe 16 is longitudinally slidably connected to the counterweight telescopic bracket 19 through a card slot. The lower end of the counterweight telescopic bracket 19 is fixedly installed with a cover control suction cup 18. The installation of the cover control suction cup 18 can make the bottom plate 12 move downward. The cover control suction cup 18 can first contact the bottle cap, and then the cover control suction cup 18 cooperates with the micro air pump 15 to make the cover control suction cup 18 adsorb the bottle cap. Then the bottom plate 12 moves up to pick up the crooked bottle cap placed on the upper end of the bottle body. Then the bottom plate 12 moves down to place the bottle cap steadily on the upper end of the bottle body again, so that the device has a bottle cap position adjustment function, ensuring that the bottle cap can be stably screwed on the upper end of the bottle body, preventing the bottle cap from being screwed obliquely, causing damage to the bottle cap, and enhancing the use effect of the device.

[0028] Working principle: When in use, the staff places the device on the upper ends of multiple production lines, and then the staff adjusts the position of the connecting bracket 7 so that the connecting bracket 7 is located directly above the production line, and then the staff tightens the limit screw 8 to fix the position of the connecting bracket 7. Next, when the production line transports the bottle body with the bottle cap to the bottom of the connecting bracket 7, the electric telescopic rod 9 extends, so that the control cap suction cup 18 first contacts the bottle cap, and then the micro air pump 15 extracts the air inside the control cap suction cup 18, and then the electric telescopic rod 9 retracts, so that the control cap suction cup 18 sucks up the bottle cap. Since the control cap suction cup 18 has a certain flexibility , and the capping suction cup 18 is installed vertically. When the lower end of the capping suction cup 18 contacts the tilted bottle cap, the lower end of the capping suction cup 18 will be deformed, and the bottle cap can also be adsorbed. When the capping suction cup 18 sucks up the bottle cap, the lower end of the capping suction cup 18 returns to its original shape, thereby ensuring that the bottle cap is also level. Then the electric telescopic rod 9 is extended again to replace the bottle cap on the upper end of the bottle body, thus achieving the position adjustment of the bottle cap. Next, the driving motor 13 drives the capping roller 14 to rotate, so that the capping roller 14 can tighten the bottle cap. The device installs the extension arm 5 so that it is installed inside the top bracket 3 through the card slot and fixed by the fixing screw 4 fixes the extension arm 5 inside the top bracket 3, so that when the device is transported, the staff only needs to unscrew the fixing screw 4 to quickly remove the extension arm 5, making the device more convenient to transport, enhancing the practicality of the device, reducing the difficulty of installation and disassembly of the device, and reducing the volume of the device during transportation.
