Abstract
The invention discloses a kind of detachable spiral knife roller of fiber cutter, including the blade installation axle in symmetrical ladder shaft-like, the blade for being provided with inner bolt hole fixes end cap and blade, described blade installation axle middle setting has column blade mounting portion of the two ends in taper type, the outer cylinder surface of the blade mounting portion is uniformly distributed circumferentially some linear cutter grooves of the cylindrical screw through blade mounting portion, also for cylindrical screw is linear on the length direction of described blade, the cutting edge of blade to be placed in cutter groove and cutting edge protrude blade mounting portion outer surface, the blade two ends are wedge shape, the blade is fixed end cap and is connected with the external screw thread at blade installation axle two ends by screwed hole, for fixing blade.The present invention is being carried out during fiber is chopped, and blade is progressively contacted with rotor along its length, reduces vibration, makes chopped process more stable, improves the quality of chopped strand.
Description
Technical field
The present invention relates to a kind of fibre chopping machine part, and in particular to a kind of detachable spiral knife roller of fiber cutter.
Background technology
At present, various fibre chopping machines mainly have punching cutting type chopping machine and rotate two kinds of cutting type cutting machine：Operationally cutter moves reciprocatingly cut staple punching cutting type cutting machine, due to there is idle stroke so inefficient；And rotate cutting type chopping machine and relatively rotated by rotor and rubber roll and realize being chopped for fiber, cutter can continuous cutting, thus production efficiency is higher.This cut-out form bottom tool cutting edge is typically all to be chopped parallel to rubber roll axis, cutting edge roundness disposably cuts rubber roll, therefore the mutation of load occurs during being chopped, produce vibration, influence chopped strand quality, it is simultaneously larger to cutter attack, cutter life is reduced, when high speed is chopped, this phenomenon is especially apparent.
The content of the invention
The present invention is for the defect for overcoming prior art to exist, there is provided a kind of cutting edge roundness can progressively cut the detachable spiral knife roller of fiber cutter of rubber roll.
The present invention is achieved through the following technical solutions：
A kind of detachable spiral knife roller of fiber cutter, including the blade installation axle in symmetrical ladder shaft-like, the blade for being provided with inner bolt hole fixes end cap and blade, described blade installation axle middle setting has column blade mounting portion of the two ends in taper type, the outer cylinder surface of the blade mounting portion is uniformly distributed circumferentially some linear cutter grooves of the cylindrical screw through blade mounting portion, also for cylindrical screw is linear on the length direction of described blade, the cutting edge of blade to be placed in cutter groove and cutting edge protrude blade mounting portion outer surface, the blade two ends are wedge shape, the blade is fixed end cap and is connected with the external screw thread at blade installation axle two ends by screwed hole, for fixing blade.
Further, the helical angle of the linear cutter groove of the cylindrical screw is 5 °, and helical length difference is 115mm.
Further, the blade is by 304 stainless steel belt punching presses, so that in circular helix on its length direction, blade is formed through high-speed grinding, easy to process, low cost.
Further, the cutting edge of the blade is provided with 3 ~ 5 μm of TiC high abrasion coatings obtained by physical gas phase deposition technology deposition, the abrasion resistance of raising cutter.
The present invention has the following advantages and effect relative to prior art：
The present invention changes the blade of existing rotor and the structure of rotor diameter parallel, design blade is on rotor axis along circular helix direction, this structure makes rotor when rotated, then blade is transitioned into another side, when the end of previous blade will be disengaged from rubber roll again first while contacted with rubber roll, the first section of latter blade has just touched rubber roll, compared with the structure that existing blade cutting edge disposably cuts rubber roll, vibrations are reduced, make operation more steady；Blade is not only cut to fiber simultaneously, also cuts sliding effect, makes fiber be easier to be cut off.
Brief description of the drawings
Fig. 1 is component structural exploded perspective view of the invention.
Fig. 2 is the circular helix cutter groove structural representation of blade installation axle of the present invention.
Fig. 3 is the structural representation of blade of the present invention.
It is shown in figure：1- blade installation axles；2- blades fix end cap；3- blades；4- blade mounting portions.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings, and the embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and is limited.
As shown in Figure 1,A kind of detachable spiral knife roller of fiber cutter,Including the blade installation axle in symmetrical ladder shaft-like,The blade for being provided with inner bolt hole fixes end cap and blade,Described blade installation axle middle setting has column blade mounting portion 4 of the two ends in taper type,The outer cylinder surface of the blade mounting portion 4 is uniformly distributed circumferentially some 24 linear cutter grooves of road cylindrical screw through blade mounting portion 4,I.e. cutter groove is circular helix along the path of the axis of blade installation axle 1,The helical angle of the linear cutter groove of cylindrical screw is 5 °,Helix difference in height is 115mm (see Fig. 2),As shown in Figure 3,Also for cylindrical screw is linear on the length direction of described blade 3,Its feature is consistent with cutter groove,The cutting edge of the blade 3 to be placed in cutter groove and cutting edge protrude blade mounting portion 4 outer surface,The two ends of the blade 3 are wedge shape,The blade is fixed end cap 2 and is connected with the external screw thread at the two ends of blade installation axle 1 by screwed hole,Mutually extruded by the wedge-shaped position with the two ends of the blade 3,Blade 3 is limited and is fixed in the cutter groove,Play a part of fixed blade 3.
In the present embodiment, the blade 3 is by 304 stainless steel belt punching presses, so that in circular helix on its length direction, blade is formed through high-speed grinding, easy to process, low cost.
In the present embodiment, the cutting edge of the blade 3 is provided with physical gas phase deposition technology（PVD）3 ~ 5 μm of TiC high abrasion coatings obtained by deposition, improve the abrasion resistance of cutter.
The rotor convenient disassembly, if blade 3 reaches service life, need to will only remove the fixed end cap 2 at the two ends of blade installation axle 1, removal 3, change new blade, compared with the structure that the cutting edge of existing blade 1 disposably cuts rubber roll, cutter groove structure in change knife roller of fiber cutter with rotor diameter parallel, devise the cutter groove with cylindrical screw cable architecture, and machined the blade 3 matched with the cutter groove structure, so as to reduce vibrations, make operation more steady, blade 3 is not only cut to fiber simultaneously, also cut sliding effect, fiber is set to be easier to be cut off.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.There is no need and unable to be exhaustive to all of implementation method.All any modification, equivalent and improvement made within the spirit and principles in the present invention etc., should be included within the protection domain of the claims in the present invention.
