Abstract

A transversely-circular material pushing screw comprises a feeding screw and a returning screw, and is characterized in that a round stop sheet is arranged at the left end of a main journal of the feeding screw and connected with a dextrorotatory equant spiral sheet, a large stop piece is arranged at the right end of the main journal and connected with a levorotatory conical spiral sheet, a large stop sheet is arranged at the left end of a main journal of the returning screw and connected with a dextrorotatory conical spiral sheet, and a round stop sheet is arranged at the right end of the main journal and connected with a levorotatory equant spiral sheet. The feeding screw and the returning screw are parallelly mounted on a feeding box, and the left ends of the two screws are connected with a motor through a gear. The transversely-circular material pushing screw can be used for uniformly pushing materials, powder can circularly and transversely flow in the feeding box without local accumulation.

Description

Technical field: [0001] The invention relates to a screw, in particular to a transverse circulation pushing screw. Background technique: [0002] Powder packaging generally uses a feeding box to control the filling amount. In order to improve packaging efficiency, multiple feeding ports are provided, and a screw is used to send the powder downward from the feeding box and fill it into the packaging bag. The feeding box is equipped with a hopper for feeding, which can be located on the side or the back of the feeding box, but horizontal pushing screws are required in the feeding box to push the powder material around each feeding screw. The form and control of the pusher screw will affect the distribution of the powder in the material box, which may accumulate on one side, making the looseness of the powder uneven and affecting the feeding accuracy. [0003] In order to prevent the powder in the feeding box from accumulating, the lateral flow direction of the powder can be c...
