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 stick conveying mechanism, a mushroom stick tray, and a bag cutting mechanism. The mushroom stick conveying mechanism includes a conveying cylinder and a support bracket, with the support bracket fixedly connected to the cylinder rod of the conveying cylinder. An electric gripper is installed on the support bracket. The bag cutting mechanism divides the mushroom stick tray into a front tray and a rear tray. The bag cutting mechanism includes an annular frame mounted on a support base, with multiple flip-return bag cutting blade components evenly distributed on the annular frame. The ends of the multiple bag cutting blade components contact at a single point, and this point lies on the same horizontal line as the center of the annular frame. An automatic mushroom bag removal machine is provided, comprising: a frame, a conveying device, a bag removal device, and a mushroom stick output device. The frame is equipped with the conveying device, and along the material transmission 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 stick 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 material movement direction.
