[0005] By adopting the above technical scheme, during processing, the beverage bottle covered with the bottle cap is placed on the processing table, and the two clamping plates move relative to each other to clamp the two sides of the beverage bottle to ensure the stability of the capping operation. After clamping, the driving mechanism is started to drive the first pulley to rotate, and the first pulley drives the tightening cylinder to rotate synchronously through the connecting rod. At the same time, the lifting assembly is started to drive the sleeve to descend relative to the limit cylinder and the support frame, so that the sleeve drives the tightening cylinder to descend synchronously, and finally the tightening cylinder is rotated and descended relative to the fixed frame. During the process, the bottle cap is embedded in the tightening cylinder, and the tightening cylinder drives the bottle cap to rotate and descend relative to the beverage bottle to realize the tightening of the bottle cap relative to the beverage bottle, thereby realizing automatic capping work, saving time and labor, and being conducive to improving the efficiency of the capping processing.

[0024] The beneficial effects of the utility model are:

[0025] 1. Start the driving mechanism to drive the first pulley to rotate, and the first pulley drives the tightening cylinder to rotate synchronously through the connecting rod. At the same time, start the lifting assembly to drive the sleeve to descend relative to the limit cylinder and the support frame, so that the sleeve drives the tightening cylinder to descend synchronously, and finally realizes the rotation and descent of the tightening cylinder relative to the fixed frame. During the process, the bottle cap is embedded in the tightening cylinder, and the tightening cylinder drives the bottle cap to rotate and descend relative to the beverage bottle to realize the tightening of the bottle cap relative to the beverage bottle, realizing automatic capping work, saving time and labor, and helping to improve the efficiency of capping processing;

[0026] 2. Rotate the horizontal screw to drive the slides on both sides to move relatively to the two sides of the beverage bottle to clamp the beverage bottle. The limit rod limits and guides the movement of the slides, thereby maintaining the stability of the beverage bottle body during the capping operation. It is suitable for beverage bottles of different specifications and improves the quality of capping.

[0027] 3. When the sleeve drives the tightening cylinder to descend, the bottle cap is first embedded in the tightening cylinder. During this period, the bottle cap pushes the tightening plate to move toward the inner wall of the tightening cylinder, and the tightening plate drives the insertion rod to move into the fixed cylinder. The compression spring contracts to provide a clamping force, so that multiple tightening plates can press the bottle caps of different specifications circumferentially, improving the applicability of the device. Then the tightening cylinder continues to rotate and descend to drive the bottle cap to rotate and press down to complete the relative tightening of the bottle cap and the bottle body.
