Solid propellant grain weighing, marking and packaging device

The invention discloses a weighing, marking and packaging device for solid propellant grains. Automatic continuous weighing, continuous marking and continuous packaging of the solid propellant grains can be achieved through automatic control. The whole technological process and the whole operation are simple, the labor intensity is low, and the safety is high. And the explosion-proof motor drives the corresponding clamping jaws to move in a gear transmission mode, so that the corresponding device is clamped, and the safety is further enhanced. According to the properties of a propellant grain and a propellant grain box cover, a pair of grain clamping jaws are arranged to be in a V shape, a box cover clamping jaw is arranged to be in an L shape, and the stability is better improved when a corresponding device is clamped. Through the pressure sensor and the light sensor, whether the clamping force of the box cover clamping jaw is enough and whether the propellant grain label is in place are automatically recogn
