Automatic cutting mechanism

The utility model relates to the technical field of cutting mechanisms, and discloses an automatic cutting mechanism, which is used for cutting vials and comprises a lower grabbing component, a cutting component and an upper grabbing component. The lower grabbing component is used for grabbing the lower end of each vial and driving the vial to rotate. The cutting component is used for cutting the vial which is driven to rotate by the lower grabbing component. The upper grabbing component is used for grabbing the upper end of the vial and moving the cut vial. The cutting component is disposed between the upper grabbing component and the lower grabbing component. The automatic cutting mechanism can be used for automatically cutting various vials, such as ampules. The lower grabbing component can be used for grabbing the lower end of each ampule, and the cutting component can be used for cutting the ampule. When cutting is compete, the upper grabbing component is capable of moving the ampule while grabbing the upper end of the ampule, so that the ampule is broken at a cut and cutting is achieved. The whole cutting process is fully automatic and highly efficient. Accuracy in cutting the ampule is high, and liquor waste is avoided.
