Numerical control automatic feeding storage bin

The invention discloses a numerical control automatic feeding storage bin which comprises a storage bin shell, the storage bin shell is arranged to be a square frame, fixing plates are arranged on the two sides of the lower end of the storage bin shell, a conveying belt is arranged between the fixing plates, the conveying belt is located below the storage bin shell, and the fixing plates, the storage bin shell and the conveying belt form a containing cavity. A containing cavity is formed by the fixing plate, the storage bin shell and the conveying belt to contain materials, meanwhile, feeding can be conducted, a driving mechanism is started to drive a discharging door to rotate and be opened, then a second motor is started, the second motor drives the conveying belt to rotate, and therefore the materials are driven to be directly conveyed and fed. The structure is simple and reasonable, the production process of plastic recycling and reusing is reduced, the traditional tedious steps of firstly storing materia
