[0037] In this embodiment, after the conveying mechanism 102 moves the bottle body and bottle cap to be tightened to the bottom of the screw cap assembly 103, the second driving device 107 drives the mounting frame 104 to move vertically downward, and the limiting component 110 slidably mounted on the clamping mechanism 106 contacts the bottle cap and can press the bottle cap onto the bottle body to maintain the stability of the bottle cap during the screw capping process; during the downward movement of the mounting frame 104, the limiting component 110, after contacting the bottle cap, moves into the mounting groove 108 until it contacts the switch 109, and the switch 109 is used to control the opening and closing of the first driving device 105, the second driving device 107 and the clamping mechanism 106. After the limiting component 110 contacts the switch 109, the second driving device 107 stops driving the mounting frame 104 moves, at this time the bottle cap is located in the clamping mechanism 106, and the clamping mechanism 106 is used to clamp the bottle cap; after the limiting component 110 contacts the switch 109, the first driving device 105 is controlled to start; the clamping mechanism 106 is rotated under the drive of the first driving device 105 to screw the bottle cap onto the bottle body; the bottom end of the limiting component 110 is rotatably mounted with a rotating part 111 through a bearing, and the rotating part 111 is used to contact the bottle cap. By setting the rotating part 111, it is possible to avoid friction between the limiting component 110 and the bottle cap during the process of the second driving device 107 driving the clamping mechanism 106 and the limiting component 110 to rotate, thereby preventing the limiting component 110 from hindering the rotation of the bottle cap and causing wear on the bottle cap surface.In this embodiment, the first driving device 105 includes a driving motor 124, a driving gear 125 coaxially fixedly connected to the output end of the driving motor 124, and a driven gear 117 sleeved on the clamping mechanism 106, the driving gear 125 is engaged with the driven gear 117, and when the driving motor 124 drives the driving gear 125 to rotate, it can drive the driven gear 117 and the clamping mechanism 106 to rotate; the second driving device 107 is a conventional telescopic rod mechanism in the prior art, and the transmission mechanism 102 is a conventional conveyor belt device in the prior art.
