Description
Technical field
The utility model relates to a kind of horizontal paper shredder, particularly relates to the horizontal paper shredder that a kind of capable of regulating forms the position, cutter positioning of horizontal paper shredder.
Background technology
In recent years, shredder has been widely used in common office space, and the disintegrating mechanism of shredder is as the critical piece of cutting paper part, and its structure function is most important for the overall performance of shredder.
Existing shredder, substantially all be to adopt paper shredder vertical, horizontal twice shredded paper, its paper shredder is generally assembled by horizontal paper shredder and vertical paper shredder, vertical paper shredder comprises a pair of strip-shaped cutter that drives rotation on knife rest along relative direction that is arranged on side by side, purpose be paper cutting is slit into vertically rectangular; Laterally paper shredder comprises the set of knives consisted of rotating screw cutting cutter shaft and fixed cutting tool, and the helical cut cutter shaft abuts against fixed cutting tool its rotation relatively, so that by the further transverse cuts of the vertical paper slip shredded paper that granulates.
, because there is defect in the package assembly of fixed cutting tool and helical cut cutter shaft, there is following shortcoming in existing horizontal paper shredder in actual use:
1, due to traditional horizontal paper shredder by arrange independently support or riser fixedly the helical cut cutter shaft by some pull bars, connected again, support and setting screw cutting cutter shaft, after laterally paper shredder moves a period of time, the bad stability of circumgyration incision cutter shaft;
2, form and must meet strict cutting gap (being generally 0-0.1mm) guarantee between the cutting edge of the cutting edge of fixed cutting tool of horizontal paper shredder and helical cut cutter shaft and pulverize quality, and manufacture and assembling process in, foozle and rigging error that the related components that affect cutting gap causes processing, in installation are inevitable.Design due to the distance between the cutting edge of the cutting edge that there is no to consider how to adjust fixed cutting tool in traditional horizontal paper shredder and helical cut cutter shaft, and the measure that how to prevent fixed cutting tool and the distortion of helical cut cutter shaft, only depend on machining accuracy and the assembling of parts to be difficult to realize satisfied crushing effect, and manufacture difficulty and the production cost of horizontal paper shredder are higher.
3, the fixed cutting tool that forms horizontal paper shredder generally is fixed by its two opposite end, so fixedly makes fixed cutting tool form the beam with both ends built-in structure.Because this structure does not design the technical measures in capable of regulating cutter gap, if the fixed cutting tool machining accuracy is inadequate, can cause the matched in clearance between the cutter group inhomogeneous.Shredder is when long-time rubbing paper, if the cutting edge of cutter weares and teares, or displacement has occurred in fixed cutting tool, capital makes cutting gap become large and causes the pulverizing Quality Down, even if more renew cutter, also can cause cutting gap to be difficult for guaranteeing because of manufacturing error of cutter, and be difficult to reach the intrinsic technical performance index of product.
4, in the shredded paper process, the built-in beam structure of fixed cutting tool can cause moment of flexure, the deflection deformation maximum of cutter mid portion, successively decrease from the middle to both ends, owing to not having design to prevent the technical measures of cutter distortion, if paper cutting is too thick, paper will enter the cutting gap between the cutter group, cutting edge is outwards strutted, support cutter phenomenon occurs, and above-mentioned situation can make paper shredder lose paper shredding function, causes shredder to work.
