Abstract
The present invention discloses a cutter shaft component of a paper cutter. The cutter shaft component comprises a main shaft and a plurality of cutter wheels which are coaxially mounted at the main shaft; a spacing piece is arranged between two adjacent cutter wheels; and the periphery of the cutter wheel is provided with a plurality of tines distributed uniformly. The cutter shaft component is characterized in that a spiral positioning device is arranged between the main shaft and the cutter wheels and the spiral positioning device ensures that the tines at adjacent cutter wheels are staggered with each other for 0.5 degree to 15 degrees sequentially, and at one moment, only one tine is contacted with paper to be crushed. The cutter shaft component has the advantages that as the spiral positioning device which ensures that the tines at the adjacent cutter wheels are staggered with each other for 0.5 degree and 15 degrees sequentially is arranged between the main shaft and the cutter wheels, so that the cutter shaft component is ensured that only one tine is contacted with the paper to be crushed at one moment, therefore, when thick paper is crushed, the driving force required by the main shaft is smaller, the selected motor power is also smaller, and the cutter shaft component has the action of crushing the paper and saves energy consumption at the same time.
Description
Technical field
The present invention relates to a kind of trimmer, especially relate to a kind of cutter shaft assembly of trimmer.
Background technology
In enterprise office, the paper that much was used and cancelled because some top data are enterprise's secret, can not just need carry out pulverization process with paper for known to the stranger, in order to avoid secret leaks, therefore just need the use shredder be pulverized by paper.The applying date be July 12 nineteen ninety-five the patent No. be the hobboing cutter group that discloses a kind of crushing type shredder in the Chinese utility model patent specification of ZL95216030.7, it is gone here and there on the main shaft of a polygon prism shape and is with break bar and distance piece, break bar and distance piece are setting separately, each break bar by and the blade that is close together constitute, and each blade periphery all has A shape pointed tooth at interval, and in the whole knife wheel set respectively organize break bar after the angle that circumferentially all staggers with spindle set, make the pointed tooth portion that respectively the organizes blade shape row example in the shape of a spiral in the knife wheel set after the assembling, and axially all form V-shaped cross type sword groove between every two-phase and two blades that are close together, during work, whole knife wheel set becomes a rolling cut with spiral pointed tooth portion and takes turns, and axially having some V-arrangement sword grooves that intersect to play the rubbing effect, make paper can reach multi-faceted crushing effect; But because main shaft is the polygon prism shape, though respectively organize break bar circumferentially stagger an angle and spindle set, but because the limit number of main shaft is limited, when pulverizing the overlapping paper of thicker paper or many, have a plurality of pointed tooths at synchronization and contact with paper to be pulverized simultaneously, at this moment, the needed driving force of main shaft can be bigger, the power of motor that needs is also bigger, and energy consumption is higher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cutter shaft assembly that can pulverize the trimmer of thicker paper with lower energy consumption.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of cutter shaft assembly of trimmer, comprise main shaft and a plurality of coaxial break bar that is set on the described main shaft, be provided with distance piece between two adjacent break bars, the periphery of described break bar is provided with a plurality of equally distributed pointed tooths, be provided with the pointed tooth that makes on the adjacent break bar between described main shaft and the described break bar and stagger 0.5 °-15 ° successively mutually, and the spiral positioning device that has only a pointed tooth to contact at synchronization with paper to be pulverized, described spiral positioning device comprises helicla flute or the helical planes that is arranged on the described main shaft and is wholely set the locating convex block on week in described break bar, described locating convex block and described helicla flute cooperatively interact or described locating convex block apical grafting on the helical centre of described helical planes, from the two ends of axially seeing described spiral fluted two ends or described helical planes with respect to the angle between the axle center less than two adjacent pointed tooths on the same break bar with respect to the angle between the axle center.
A kind of cutter shaft assembly of trimmer, comprise main shaft and a plurality of coaxial break bar that is set on the described main shaft, be provided with distance piece between two adjacent break bars, the periphery of described break bar is provided with a plurality of equally distributed pointed tooths, be provided with the pointed tooth that makes on the adjacent break bar between described main shaft and the described break bar and stagger 0.5 °-15 ° successively mutually, and the spiral positioning device that has only a pointed tooth to contact at synchronization with paper to be pulverized, described spiral positioning device comprises and is arranged on the locating slot on week in the described break bar and is wholely set spiral prominence footpath on described main shaft, described spiral prominence footpath cooperatively interacts with described locating slot, from the two ends of axially seeing described spiral prominence footpath with respect to the angle between the axle center less than two adjacent pointed tooths on the same break bar with respect to the angle between the axle center.
Compared with prior art, advantage of the present invention is owing to be provided with the pointed tooth that makes on the adjacent break bar 0.5 °-15 ° the spiral positioning device that staggers mutually successively between main shaft and the break bar, make the cutter shaft assembly have only a pointed tooth to contact with paper to be pulverized at synchronization, when pulverizing thicker paper, the needed driving force of main shaft is just smaller, the power of motor of selecting for use is also smaller, plays and has also saved energy consumption when pulverizing the paper effect; In addition because the spiral positioning device adopts helicla flute on the main shaft and the locating convex block on the break bar to cooperatively interact or adopts helical planes and the structure that the locating convex block on the break bar cooperatively interacts on the main shaft, process more convenient, and locate also more firm.
