[0012] Compared with the prior art, a high-speed key finger rejection mechanism adopting the above technical scheme has the following beneficial effects:

[0013] First, in use, the unqualified bottles with different-color bottle caps are rejected through the bellows, the push column, the spring, the push plate and the air cylinder. At the same time, the whole device only needs one air cylinder to drive, thereby reducing the complexity and manufacturing cost of the device, and thus reducing the overall cost.

[0014] Second, in use, the bellows is limited by the chute and the sliding rod to prevent the bellows from shifting, thereby improving the stability of the bellows during movement. The color of the bottle cap on the conveyor belt is detected by the color mark sensor. When different colors are detected, the information is transmitted to the PLC controller, and the air cylinder is started after two seconds to drive the bellows to reject the bottle with a different-color bottle cap to the conveyor belt on the right side. Therefore, it can automatically identify and automatically reject, realizing the full-automatic control from detection to rejection, and improving the intelligent level of the production line.

[0015] Third, in use, the mounting box can be disassembled and assembled by the staff through the mounting plate and the bolt, which is convenient for the staff to clean or maintain, and improves the convenience of equipment maintenance.
