Abstract
The utility model discloses a can dismantle spiral fibre chopping machine rotor, including the blade installation axle that is symmetrical step shaft form, fixed end cover of blade and the blade that is provided with inner screw hole, blade installation axle in the middle of be provided with the column blade installation department that both ends are frustum shape, outer cylindrical surface along a plurality of circular helix shape sword grooves of running through the blade installation department of circumference evenly distributed of blade installation department, the length direction of blade on also for circular helix shape, the surface of sword inslot and blade protrusion blade installation department is outwards arranged in to the blade of blade, the blade both ends are the wedge, the external screw thread that the axle both ends were installed through screw hole and blade to the fixed end cover of blade is connected for fixed blade. The utility model discloses carrying out the short eager in -process of fibre, the blade is followed length direction and is progressively contacted with the rotor, has reduced the vibration, makes the short process of cutting more stable, has improved chopped fiber's quality.
Description
Technical field
The utility model relates to a kind of fibre chopping machine parts, is specifically related to a kind of detachable spiral knife roller of fiber cutter.
Background technology
At present, various fibre chopping machine mainly contains punching cutting type chopping machine and rotates cutting type cutting machine two kinds: punching cutting type cutting machine operationally cutter moves reciprocatingly cut staple, owing to there is idle stroke so efficiency is not high; And rotate cutting type chopping machine and relatively rotated by rotor and rubber roll and realize the short of fiber and cut, cutter can continuous cutting, and thus production efficiency is higher.This cut-out form bottom tool cutting edge is all generally be parallel to that rubber roll axis is short to be cut, the disposable incision rubber roll of cutting edge roundness, therefore cut through in journey short the sudden change that there will be load, produce vibration, affect staple fiber quality, simultaneously comparatively large to cutter attack, reduce cutter life, high speed is short cut time this phenomenon especially obvious.
Utility model content
The defect that the utility model exists to overcome prior art, provides the detachable spiral knife roller of fiber cutter that a kind of cutting edge roundness progressively can cut rubber roll.
the utility model is achieved through the following technical solutions:
A kind of detachable spiral knife roller of fiber cutter, comprise the blade installation shaft of symmetrically ladder shaft-like, the blade being provided with inner bolt hole fixes end cap and blade, the column blade mounting portion that two ends are taper type is provided with in the middle of described blade installation shaft, the outer cylinder surface of described blade mounting portion is uniformly distributed circumferentially some linear cutter grooves of cylindrical screw running through blade mounting portion, the length direction of described blade is also cylindrical screw is linear, the cutting edge of blade is to be placed in cutter groove and cutting edge protrudes the outer surface of blade mounting portion, described blade two ends are wedge shape, described blade is fixed end cap and is connected by the external screw thread of screwed hole with blade installation shaft two ends, for fixed blade.
Further, the helical angle of the linear cutter groove of described cylindrical screw is 5 °, and helical length difference is 115mm.
Further, described blade by 304 stainless steel belt punching presses, thus makes in cylindrical helix on its length direction, and blade forms through high-speed grinding, easy to process, and cost is low.
Further, 3 ~ 5 μm of TiC high abrasion coatings that the cutting edge of described blade is provided with physical gas phase deposition technology deposition and obtains, improve the abrasion resistance of cutter.
the utility model, relative to prior art, has following advantage and effect:
The utility model changes the blade of existing rotor and the structure of tool roller axis line parallel, design blade on rotor axis along cylindrical helix direction, this structure makes rotor when rotated, blade first while contact with rubber roll, and then is transitioned into another side, when the end of last blade will depart from rubber roll, first section of a rear blade just touches rubber roll, compared with the structure of the disposable incision rubber roll of existing blade cutting edge, reduce vibrations, make operation more steady; Blade not only has the effect of cutting to fiber simultaneously, cuts sliding effect in addition, fiber is more easily cut off.
Accompanying drawing explanation
Fig. 1 is component structural exploded perspective view of the present utility model.
Fig. 2 is the cylindrical helix cutter groove structural representation of the utility model blade installation shaft.
Fig. 3 is the structural representation of the utility model blade.
Shown in figure be: 1-blade installation shaft; End cap fixed by 2-blade; 3-blade; 4-blade mounting portion.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described further the utility model below in conjunction with accompanying drawing, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
As shown in Figure 1, a kind of detachable spiral knife roller of fiber cutter, comprise the blade installation shaft of symmetrically ladder shaft-like, the blade being provided with inner bolt hole fixes end cap and blade, the column blade mounting portion 4 that two ends are taper type is provided with in the middle of described blade installation shaft, the outer cylinder surface of described blade mounting portion 4 is uniformly distributed circumferentially some linear cutter grooves of 24 road cylindrical screw running through blade mounting portion 4, namely cutter groove is cylindrical helix along the path of blade installation shaft 1 axis, the helical angle of the linear cutter groove of described cylindrical screw is 5 °, screw line difference in height is 115mm (see Fig. 2), as shown in Figure 3, the length direction of described blade 3 is also cylindrical screw is linear, its feature is consistent with cutter groove, the cutting edge of described blade 3 is to be placed in cutter groove and cutting edge protrudes the outer surface of blade mounting portion 4, described blade 3 two ends are wedge shape, described blade is fixed end cap 2 and is connected by the external screw thread of screwed hole with blade installation shaft 1 two ends, by extruding mutually with the wedge shape position at described blade 3 two ends, blade 3 is limited and is fixed in described cutter groove, play the effect of fixed blade 3.
In the present embodiment, described blade 3 by 304 stainless steel belt punching presses, thus makes in cylindrical helix on its length direction, and blade forms through high-speed grinding, easy to process, and cost is low.
In the present embodiment, 3 ~ 5 μm of TiC high abrasion coatings that the cutting edge of described blade 3 is provided with physical gas phase deposition technology (PVD) deposition and obtains, improve the abrasion resistance of cutter.
This rotor convenient disassembly, if blade 3 arrives service life, only need will take off the fixing end cap 2 at blade installation shaft 1 two ends, removal 3, change new blade, compared with the structure of the disposable incision rubber roll of existing blade 1 cutting edge, change the cutter groove structure with tool roller axis line parallel in knife roller of fiber cutter, devise the cutter groove with cylindrical screw line structure, and machined the blade 3 matched with this cutter groove structure, thus reduce vibrations, make operation more steady, blade 3 pairs of fibers not only have the effect of cutting simultaneously, cut sliding effect in addition, fiber is more easily cut off.
Above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
