The application discloses an execution mechanism for bundling and stacking materials and a bundling device. The execution mechanism comprises a head device and a
relay device. The head device is used for feeding a belt around a first belt passing channel at a first corner. The
relay device is used for receiving and fixing a bundling belt in the first belt passing channel and feeding the belt after receiving and fixing the end of the bundling belt in the first belt passing channel. The
relay device is used for feeding the received bundling belt into a second belt passing channel around a second corner at a second corner. The head device is used for receiving the bundling belt in the second belt passing channel and tightening,
welding and
cutting the received bundling belt around the first corner and the second corner. The execution mechanism realizes automatic bundling of the stacking materials in multidimensional directions, has high working efficiency, saves manpower, reduces the bundling cost, and guarantees the bundling quality and the bundling effect.
