Detailed description of the invention
In conjunction with Figure of description, describe detailed description of the invention of the present utility model in detail:
It as shown is a kind of driving drum, two flange 6 being perpendicular to bobbin longitudinal center line it are symmetrical arranged in bobbin 7, the outer rim of flange 6 is welded and fixed with bobbin 7 inwall, connected by the centre bore of two flange 6 and power transmission shaft 8 is set, it is fixing that power transmission shaft 8 uses singly-bound or expansion set to be connected with the centre bore of flange 6, connect respectively in 7 liang of ora terminalis cylinders of bobbin and end cap seat 2 is set, end cap seat 2 is circular ring structure, to being embedded at bobbin 7 ora terminalis, outer rim is welded and fixed with the inwall of bobbin 7, the diameter of the big axis hole in center 201 is more than the diameter of power transmission shaft 8, make to constitute big annular gap between the hole wall of the big axis hole of power transmission shaft 8 and center 201, to meet butt plate 6 to coordinate the needs of putting maintenance into practice with the connection of power transmission shaft 8；Connect outside end cap seat 2 and Flat Lid 1 is set, Flat Lid 1 selects antifriction metal (AFM) or wear-resisting nonmetallic materials to make, fixed with end cap seat 2 by connecting bolt 4, fixing nut 5 and be connected, Flat Lid 1 is convex panel type circular ring structure, and use integral type or split modular structure, the diameter of its central shaft hole 101, slightly larger than the diameter of power transmission shaft 8, makes central shaft hole 101 constitute without bite matched in clearance with power transmission shaft 8 surface；The big external diameter of Flat Lid 1 is consistent with the external diameter of bobbin 7, convex outer diameter is consistent with the internal diameter of bobbin 7, convex surface height embeds the degree of depth in bobbin 7 unanimously with end cap seat 2, constitutes the Flat Lid 1 end face respectively with bobbin 7, end cap seat 2 and contacts the attachment structure coordinated；One group of end cap installing hole 202 circumferentially it is equipped with on end cap seat 2, the outside of end cap installing hole 202 arranges fixing nut 5 with its concentricity welding, on Flat Lid 1, the position of corresponding end cap installing hole 202 arranges one group of counterbore installing hole 102, the counterbore degree of depth of counterbore installing hole 102 is spirally connected fixing through counterbore installing hole 102, end cap installing hole 202 with fixing nut 5 not less than the screw head height of connecting bolt 4, connecting bolt 4.
In above-described embodiment, for simplifying installation process, can arrange female thread in end cap installing hole 202, connecting bolt 4 is spirally connected fixing with connecting bolt 4 after counterbore installing hole 102.
In above-described embodiment, a set of sealing and dustproof assembly 3 can be respectively provided with by the Flat Lid 1 of bobbin 7 both side ends, form wire gear between sealing and dustproof assembly 3 and Flat Lid 1 and touch sealing；When driving drum rotation work, the airborne dust that material is left and produces effectively is stopped by sealing and dustproof assembly 3 at the both side ends of bobbin 7 and cannot release to dustless region, the most just efficiently solves the driving drum of the existing ribbon conveyer sealing dust-break problem at the both side ends of bobbin 7.During it addition, ribbon conveyer runs, Flat Lid 1 rotates with bobbin 7, and sealing and dustproof assembly 3 is static, between Flat Lid 1 and sealing and dustproof assembly 3 for being association of activity and inertia, wire-shaped contact seal, therefore, the abrasion of Flat Lid 1 will be unavoidably；Flat Lid 1 uses convex panel type circular ring structure; contact respectively with the end face of bobbin 7, end cap seat 2 and coordinate; can effectively ensure that the intensity of Flat Lid 1; and when the plate surface wear of Flat Lid 1 is bigger; as long as being backed out by connecting bolt 4, the ora terminalis that the most replaceable new Flat Lid 1 is so just effectively protected bobbin 7 is not worn.
