Abstract
The utility model discloses a polygon cutter shaft, wherein the cross section of the member used for blade-installation is a polygon. The utility model is characterized in that each side of the member used for blade-installation is equidirectionally rotating spiral curved surface. The tool angle can be staggered through the cutter spindle while wearing the blade, creating a time difference when the cutter point cuts paper, which can effectively reduce motor load and power consumption. The utility model has the advantages of easy assembly which can improve production efficiency, particularly applicable to shredders or the like.
Description
Technical field
The utility model relates to the cutter shaft of shredder or broken CD player, particularly a kind of polygon cutter shaft that is used for shredder or broken CD player.
Background technology
Existing shredder or or broken CD player cutter shaft, its part that is used to install blade is generally the garden cylindricality, and in order to locate the blade on the cutter shaft, general cutter shaft is provided with axial spacer pin or locating slot, its contraposition when blade is installed is cumbersome and make mistakes easily, thereby is not easy assembling.Occurred the polygon cutter shaft afterwards again, promptly cross section is polygon and the side is the cutter shaft of rectangular planes, has solved the defective that garden cylindricality cutter shaft exists preferably.But, all there are a common shortcoming in existing garden cylindricality cutter shaft and polygon cutter shaft, promptly be subjected to its structural limitations, the point of a knife that is installed in all blades on the cutter shaft is all on same straight line, also be that shredder is all blades while cut papers on the cutter shaft when shredded paper, thereby need bigger power to drive cutter shaft, for the shredder that motor drives, then meaning needs to be equipped with load and all bigger motor of power consumption.
Summary of the invention
Technical problem to be solved in the utility model is a kind of assembling and can effectively reduce the polygon cutter shaft that drives the required strength of cutter shaft easily when blade is installed of exploitation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this polygon cutter shaft, its cross section that is used to install blade section is polygon, it is characterized in that its each side that is used to install blade section is the spirality curved surface to same direction rotation.The spirality curved surface is meant: the line of the intersection point of the cross section of cutter shaft and two helixes rotates formed curved surface around the axis of cutter shaft, and described two helixes are meant the helix that axially equidistantly distributes at cutter shaft.
Be convenient processing and install that the cross section of cutter shaft is preferably designed as regular polygon, and be good with regular hexagon in the regular polygon.For regular polygon, described spirality curved surface is meant: the line of the intersection point of the cross section of cutter shaft and two garden post helixes rotates formed curved surface around the axis of cutter shaft, and described two circular helixes are meant the circular helix that axially equidistantly distributes at cutter shaft.
The spiral angle of described spirality curved surface is 0.1～30 °, is preferably 1～10 °.
The described two ends that are used to install the part of blade are provided with the cannelure that is used to install clip.
One end of cutter shaft also forms the gear shaft that is used to install gear.
Compared with prior art, advantage of the present utility model is: the point of a knife angle can stagger by the spiral of cutter shaft itself when wearing blade, each group point of a knife is produced a time difference at cut paper or when cutting CD, drive the required strength of cutter shaft thereby can effectively reduce, for the shredder that motor drives, then can effectively reduce motor load and power consumption, also have the advantage of easy assembling simultaneously, help enhancing productivity, and the market competitiveness that improves shredder etc.
