Cutter detection mechanism and automatic packaging machine

The utility model provides a cutter detection mechanism and an automatic packaging machine. The cutter detection mechanism comprises a conveying mechanism, a feeding mechanism, a detection mechanism, a discharging and transferring mechanism and an integrated controller for controlling all the mechanisms to work. The conveying mechanism is used for providing a material storage disc loaded with cutters; the feeding mechanism comprises a material taking mechanical arm and a driving module used for driving the material taking mechanical arm to take materials and transport the materials. The detection mechanism comprises a detection position used for clamping and fixing a cutter, a detection machine used for detecting the cutter and a lifting device used for driving the detection position to ascend and descend in the vertical direction. The detection position is provided with a positioning piece for placing a cutter, and a first clamping piece and a second clamping piece which form clamping on two sides of the pos
