A cross circulation pushing screw comprises a feeding screw and a returning screw. The cross circulation pushing screw is characterized in that a circular stopper is arranged at the left end of a main journal of the feeding screw and connected with a right-handed equal-diameter spiral fin, a large stopper is arranged at the right end of the main journal of the feeding screw and connected with a left-handed conical spiral fin, a large stopper is arranged at the left end of a main journal of the returning screw and connected with a right-handed conical spiral fin, and a circular stopper is arranged at the right end of the main journal of the returning screw and connected with a left-handed equal-diameter spiral fin. The feeding screw and the returning screw are parallelly mounted on a discharging box, and the left ends of the feeding screw and the returning screw are connected with a motor through gears. Materials can be uniformly pushed, powder can circularly flow left and right in a work bin, and local accumulation is avoided.
Description
Technical field:
The present invention relates to a kind of screw rod, particularly a kind of traverse cycle pushing screw rod.
Background technology:
The general lower feed box control loading that adopts of pulvis packing is provided with a plurality of feed openings for improving packaging efficiency, adopts screw rod that pulvis is seen off by lower feed box downwards, is filled in the packaging bag.Lower feed box is equipped with the hopper that is used to feed in raw material, and can be positioned at the hopper side or the back side, but all needs horizontal pushing screw rod in the lower feed box, and the pulvis material is shifted onto around each blanking screw rod.The form of pushing screw rod will influence the distribution of pulvis in hopper with control, possibly appear at the phenomenon of piling up on one side, make the pulvis loosening degree uneven, influence cutting stock precision.
In order not allow the pulvis in the lower feed box to produce accumulation, can change pulvis transverse flow direction through changing the pushing screw rod local structure; It can be circulated in lower feed box; Thereby do not influence the pulvis loosening degree, just do not influence cutting stock precision yet, just pack precision.
Summary of the invention:
Goal of the invention: the present invention provides a kind of traverse cycle pushing screw rod, its objective is pulvis to be packaged can cycles back and forth be flowed in lower feed box, does not produce local accumulation.
Technical scheme: the present invention implements according to following technical scheme: a kind of traverse cycle pushing screw rod; Constitute by feeding spiro rod (1) and feed back screw rod (6); The crank journal left end that it is characterized in that feeding spiro rod (1) is provided with round catch (2) and links to each other with the isometrical flight of dextrorotation (3), and the crank journal right-hand member is provided with big catch (5) and links to each other with left-handed awl flight (4); The crank journal left end of feed back screw rod (6) is provided with big catch (10) and links to each other with dextrorotation awl flight (9), and the crank journal right-hand member is provided with round catch (7) and links to each other with left-handed isometrical flight (8).
Circle catch (2), the isometrical flight of dextrorotation (3), circle catch (7) are identical with the external diameter of left-handed isometrical flight (8); Big catch (5) is identical with the external diameter of big catch (10); Big catch (5) external diameter is 1-2 a times of circle catch (2) external diameter; The external diameter of left-handed awl flight (4) is decreased to the external diameter of the isometrical flight of dextrorotation (3) gradually from the external diameter of big catch (5); The external diameter of dextrorotation awl flight (9) reduces the external diameter of left-handed isometrical flight (8) gradually from the external diameter of big catch (10).
Left-handed awl flight (4) and dextrorotation awl flight (9) are 1-3 circle flight; The space that 5mm-20mm is all arranged between the end of the end of left-handed awl flight (4) and the isometrical flight of dextrorotation (3) and between the end of the end of dextrorotation awl flight (9) and left-handed isometrical flight (8).
Feeding spiro rod (1) and feed back screw rod (6) are installed in parallel on the lower feed box (11), and left end links to each other with electrical motor (13) through gear (12).
Advantage and effect: through enforcement of the present invention, a kind of traverse cycle pushing screw rod can be carried out even pusher, and pulvis can cycles back and forth flow in hopper, does not produce local accumulation.

Mark among the figure: 1-feeding spiro rod, 2,7-circle catch, the isometrical flight of 3-dextrorotation, the left-handed awl flight of 4-, 5, the big catch of 10-, 6-feed back screw rod, the left-handed isometrical flight of 8-, 9-dextrorotation awl flight, 11-lower feed box, 12-gear, 13-electrical motor, 14-hopper.
The specific embodiment:
A kind of traverse cycle pushing screw rod; Constitute by feeding spiro rod (1) and feed back screw rod (6); The crank journal left end that it is characterized in that feeding spiro rod (1) is provided with round catch (2) and links to each other with the isometrical flight of dextrorotation (3), and the crank journal right-hand member is provided with big catch (5) and links to each other with left-handed awl flight (4); The crank journal left end of feed back screw rod (6) is provided with big catch (10) and links to each other with dextrorotation awl flight (9), and the crank journal right-hand member is provided with round catch (7) and links to each other with left-handed isometrical flight (8).
Circle catch (2), the isometrical flight of dextrorotation (3), circle catch (7) are identical with the external diameter of left-handed isometrical flight (8); Big catch (5) is identical with the external diameter of big catch (10); Big catch (5) external diameter is 1-2 a times of circle catch (2) external diameter; The external diameter of left-handed awl flight (4) is decreased to the external diameter of the isometrical flight of dextrorotation (3) gradually from the external diameter of big catch (5); The external diameter of dextrorotation awl flight (9) reduces the external diameter of left-handed isometrical flight (8) gradually from the external diameter of big catch (10).
