Description
Technical field
The present invention relates to cutting blade field, especially a kind of rotation knife system that can be compensated automatically.
Background technique
In existing cutting equipment, including blade and cutterhead, blade are movable blade, and cutterhead is fixing cutter, and blade is tightly attached to
On cutterhead, when cutting, material is fed from insert orientation, and hollow hole discharges from cutterhead；Blade is rotated relative to cutterhead, to be formed
Cutting to material.For movable blades in cutting process, the edge of a knife contacted with cutterhead can accordingly generate abrasion, grind in movable blades
After damage, gap is then formed between movable blades and cutterhead, influences cutting effect and blade life.In the prior art, occurring
After cutter blade wears, needs manually to be adjusted, compensates abrasion.The mode of this compensation abrasion is not only cumbersome, but also
It needs to carry out under shutdown status, to ensure safety；Cannot work continuously the defect low with production efficiency accordingly, there exist equipment,
It needs to improve.
Summary of the invention
Goal of the invention of the invention is: asking for need to manually adjust after cutter blade wears of the existing technology
Topic realizes that cutting blade is compensated automatically upon wear.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of rotation knife system that can be compensated automatically, including rotary shaft and the blade for being fixedly connected on rotary shaft one end,
It is characterized in that, further including the cutterhead and mounting base of fixed setting；Cutterhead is between mounting base and blade；It wears rotary shaft front end
Cutterhead is crossed, rotary shaft is removable, and is rotatably arranged in mounting base, tail end of the mounting base close to rotary shaft；The tail of rotary shaft
End is connected with bearing block by first bearing, and bearing block is able to drive rotary shaft towards far from the movement of mounting base direction；Bearing block with
Thrust part is equipped between mounting base, thrust part pushes bearing block far from mounting base, so that blade is close to cutterhead.

In cavity；It is formed with male-female structure between the cavity inner wall and bearing block of mounting base, the male-female structure is for preventing
Bearing block rotation；Bearing block is cylindrical in shape structure, and the nozzle of bearing block has outwardly extending flange；Thrust part both ends are against method
Between the blue and bottom of chamber of cavity.To make full use of the rolling friction characteristic of first bearing, bearing block is avoided to form phase with mounting base
To rotation, a variety of optional modes is provided for the selection of thrust part and with the connection formation of the two, it is ensured that thrust part fortune
Row is reliable.
As a preferred solution of the present invention, wherein thrust part is hydraulic cylinder.Perseverance can be formed by setting cylinder pressure
Determine the automatic compensation driving of thrust；The abrasion condition of blade can also be speculated by the oil pressure of hydraulic thrust.
As a preferred solution of the present invention, wherein knife handle is fixed by the fixture nut screwed togather in rotary shaft；Fixture nut
Nut set is equipped between knife handle.It makes full use of existing threaded fastener to realize that knife handle is fixed, to simplify structure, reduces cost.
As a preferred solution of the present invention, wherein above-mentioned first bearing is thrust ball bearing；Above-mentioned second bearing is
Deep groove ball bearing.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, blade is in cutting, and after generating gap with cutterhead, thrust bearing bearing drives rotary shaft mobile, so that blade and knife
The disk moment is held against state, realizes the purpose of automatic compensation gap blade.
2, staff can judge the abrasion condition of blade by observing the oil pressure situation of hydraulic cylinder.When hydraulic cylinder
For oil pressure lower than the first preset threshold and when stablizing constant, staff may determine that blade has worn out and bearing block has pushed
Rotary shaft compensates.When the oil pressure of hydraulic cylinder is lower than the second preset threshold, staff carries out more allowing blade replacement, avoids knife
Piece replacement influences cut quality and damage cutterhead or other component not in time.
3, the device adjustment mode that this programme provides is simple, is not take up the working time, improves the working efficiency of cutting；Simultaneously
The utilization rate for improving blade, reduces operating cost.
