Spiral cross cutter shaft structure, which includes the upper and lower cutter shaft. The upper and the lower cutter shaft are respectively hinged on the rack gear box through the traveling end bearing seat and the fixed end bearing seat at both ends of the upper and the lower knife shaft, the first cylindrical hole cylindrical roller bearing and the conical hole cylindrical roller bearing , The first cylindrical hole cylindrical roller bearings located on the swimming end of the bearing housing, tapered roller cylindrical roller bearings located outside the tourniquet, the middle of the first spacer and the second spacer to separate the two bearings inside and outside The inner ring of the circular and conical bore cylindrical roller bearing and the upper and lower cutter shafts are expanded and fastened by the first bearing sleeve. The outer ring of the first cylindrical cylindrical roller bearing and the tapered cylindrical cylindrical roller bearing is pressed by the first bearing The cover is pressed and fixed, and the pedestal on the traveling end is sealed with the upper and lower cutter shafts through the first oil seal and the second oil seal, and the grease is injected into the sealed space. Cross-cutting machine adopts the structure of the spiral cross cutter blade shaft structure after the support structure of good rigidity, small deflection, improve the operation of the knife shaft accuracy, the knife shaft structure more compact.
Which belongs to the field of corrugated board equipment manufacturing, in particular to a knife roll for a spiral cross-cutting machine, which comprises a roll body and a cutter mounted on the roll body. The utility model is characterized in that the roll body is a non-rotating body structure, Surface is thin-walled structure. The side wall of the roller body of the non-rotating body structure is balanced with a rotation of 180 degrees by a base point of the roller body. The thin wall of the non-cutter mounting surface is a sanded surface. The tool mounting surface is a mounting surface, the 180-degree rotating surface is an arc surface, and the surface of the mounting surface and the arc surface are balanced in weight. The two knives are symmetrically arranged on the outer wall of the roller body. The knife roller used for the spiral crosscutting machine adopting the structure has the advantages of light weight, small power consumption and high cutting precision.
Which belongs to the field of manufacturing corrugated board equipment, and in particular relates to a knife roller driving device of a spiral crosscutting machine, which comprises a machine frame, knife rolls, a gear box mounted on the side ends of the knife rolls, and a driving motor. The utility model is characterized in that two End with gearbox and drive motor. The knife roller driving device of the spiral crosscutting machine of the structure adopts the force balance of the knife roller and the stable operation to ensure the cutting quality.
