The invention relates to the technical field of screw blanking, in particular to a blanking screw sleeve hot drawing film forming square opening feeding structure which comprises a feeding body and a feeding body communicated with the bottom of the feeding body, the feeding body comprises a hopper, the hopper is provided with a material opening, the feeding body comprises an outer
barrel, the outer
barrel is provided with an outer opening, the outer
barrel is provided with an inner barrel, and the inner barrel is provided with an inner opening. A through opening is formed in the inner cylinder, and a second motor is arranged on one side of the through opening and penetrates through the through opening to be in transmission connection with a screw. The
powder feeding device has the advantages that the material circulation sectional area is increased by adopting a square opening
butt joint mode, the probability of material bridging is reduced, so that
powder materials are conveniently discharged, in addition, the upper opening and the lower opening are formed, the feeding body and the feeding body are conveniently combined and installed, the side opening is formed, a
handle is held, and the side disc is rotated in the side opening, so that the
powder feeding device is convenient to use. And the stirring body is driven to rotate in the hopper, so that materials can be stirred, and blockage of the materials is avoided.
