It is in contact to the end face of mounting plate 31.Cut-off knife spring 13 can be by circular shear blade 11 to 31 force feed of mounting plate, and idler wheel 17 and idler wheel O
Type circle 18 can hold circular shear blade 11, and when operation, the frictional force between idler wheel O-ring 18 and circular shear blade 11 makes idler wheel 17 and idler wheel
O-ring 18 also rotates together, and the support force that 11 cycle surface of circular shear blade has idler wheel O-ring 18 to provide can allow circular shear blade 11
It rotates more steady.
As shown in Figures 2 and 3, the blade of circular shear blade 11 is equipped with an inclination angle towards the side of cover board 32.This inclines
The axial force that oblique angle can make circular shear blade 11 suffered when cutting a sheet of paper is towards the direction of mounting plate 31, and this direction is exactly rolled
Wheel 17 and idler wheel O-ring 18 hold the side of circular shear blade 11, more stable, the route of cutting a sheet of paper that circular shear blade 11 can be made to operate
It is more straight.
18 material of idler wheel O-ring is natural rubber, nitrile rubber or polyurethane rubber.Natural rubber, nitrile rubber or poly-
Urethane rubber elasticity with higher and wearability, such material can be such that idler wheel O-ring 18 and circular shear blade 11 contacts surely
It is fixed, face sliding will not be in contact, situations such as vibration.
The steel wire line footpath that cut-off knife spring 13 uses is 1.5~2.5mm, and the steel wire line footpath that bar shaped flat spring 24 uses is 0.6
~1.2mm.The more big then coefficient of elasticity of the steel wire line footpath of spring is higher.Cut-off knife spring 13 can be made using higher elasticity coefficient spring
Circular shear blade 11 is not susceptible to axial displacement when running, and bar shaped flat spring 24 can make pressure roller 21 using low elastic coefficient spring
It is not too big to the pressing force of paper and cause the process of cutting a sheet of paper not smooth.
In use, sliding execution machine 2 drives cut-off knife main body 3 to slide along guide rail 1, circular shear blade 11 is cut along motion path
The paper under it is cut, while itself also will drive the rotation of axis 16 due to frictional force etc., is connect with 11 1 side end face of circular shear blade
For the idler wheel O-ring 18 of touching also due to frictional force drives idler wheel 17 to rotate around its mounting axis, idler wheel O-ring 18 is constantly circle
The side of shape blade 11 provides support force.Bar shaped flat spring 24 gives stripe board 22 and pressure roller 21 1 compressions towards paper
Power, and allow pressure roller 21 and stripe board 22 to make a concession upwards when pressing force of the pressure roller 21 to paper is excessive, pressure roller 21
It pushes down paper of the circular shear blade 11 before and after direction of cutting a sheet of paper and is rolled along direction of cutting a sheet of paper.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
