A mushroom bag removal machine, comprising: a frame and a panel located at the top of the frame, with an air pump and a control box installed inside the frame. The panel is equipped with a mushroom bag removal mechanism, characterized in that: the mushroom bag removal mechanism includes a mushroom bag conveying mechanism, a mushroom bag tray, and a bag cutting mechanism. The mushroom bag conveying mechanism includes a conveying cylinder and a support frame, with the support frame fixedly connected to the cylinder rod of the conveying cylinder. An electric gripper is installed on the support frame. The bag cutting mechanism divides the mushroom bag tray into a front tray and a rear tray. The bag cutting mechanism includes an annular frame mounted on a support base, with multiple retractable and resettable bag cutting blade assemblies evenly distributed on the annular frame. The ends of the multiple bag cutting blade assemblies contact at a single point, and this point lies on the same horizontal line as the center of the annular frame. Provides an automatic mushroom bag removal machine, comprising: a frame, a conveying device, a bag removal device, and a mushroom bag output device. The frame is equipped with the conveying device, and along the material conveying direction of the conveying device, the bag removal device is arranged. The tail end of the conveying device is connected to the feed end of the mushroom bag output device. The bag removal device includes: a drilling device, a flipping device, a horizontal cut, a vertical cut, a tearing device, and a pushing device. The drilling device, flipping device, horizontal cut, vertical cut, tearing device, and pushing device are sequentially arranged on the frame along the direction of material movement.
