Description
Technical field
The present invention relates to a kind of cutter sweep, particularly a kind of for cutting the Circular cutter of flexible material and there is the cutting machine of this Circular cutter.
Background technology
The base paper web width produced of current paper machine is comparatively large, and what have widely reaches nearly ten meters.But paper manufacture out after, in follow-up process, due to the impact of following process board size, paper mill need the paper roll of larger fabric width is cut into the less paper roll of several fabric width.And the wide paper than these paper rolls of the paper of finished paper is wide also much smaller, therefore also need paper roll to cut.In the operation that these are cut, cutting machine can be used.
Cutting machine for cutting the material such as paper, film has been applied very extensive.But cutting paper for daily use is more special, because paper for daily use is crimped paper, comparatively soft, so the paper cutting this softness is very high to the requirement of Circular cutter.And although current used Circular cutter successfully can cut off the body paper as paper for daily use, often the body paper place of cutting can be torn and produce burr phenomenon, add difficulty of processing and the loss of body paper.
Summary of the invention
The present invention aims to provide a kind of Circular cutter and has the cutting machine of this Circular cutter, to address the aforementioned drawbacks.
A kind of Circular cutter, comprise circular cutter hub and be distributed in the cutter tooth of cutter hub periphery, each cutter tooth comprises two relative sides end face relative with two, wherein the side of cutter tooth is extended by the respective side of cutter hub, the side of each cutter tooth and end face intersect at the summit of this cutter tooth, two end faces of each cutter tooth are along being symmetric by the straight line of the summit of corresponding cutter tooth and the mid point of cutter hub axis, and two of each cutter tooth sides are along being symmetric by the straight line of the summit of corresponding cutter tooth and the mid point of cutter hub axis.
A kind of cutting machine, the Circular cutter comprising support, driving member and be rotatably connected on driving member, this Circular cutter is above-mentioned Circular cutter.
Compared with prior art, due to the unique design of the cutter tooth of Circular cutter of the present invention, it has the structure of full symmetric, therefore uniform force application, and the point of application is single, can not produce burr phenomenon when cutting thin material, thus reduce the wastage, be convenient to the following process of thin material.
The thinner material that Circular cutter of the present invention is particularly suitable for rising paper for daily use etc. such softness of wadding cuts, and also may be used for requiring higher, to cut other thin materials such as film etc. without burr generation cutting to the regularity at the place of cutting.
With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of Circular cutter 10 provided by the invention, comprises circular cutter hub 12 and is distributed in the cutter tooth 14 of cutter hub 12 periphery.
Cutter hub 12 has two relative sides 123,124.Side 123,124 is plane and parallel to each other, and the distance between two sides 123,124 is the thickness of cutter hub 12.The L place, axis of cutter hub 12 offers axis hole 121.The large I of axis hole 121 decides according to the required scantling of installing of cutter hub 12.Cutter hub 12 also offers some fixing holes 122 in the surrounding of axis hole 121.For fixture, these fixing holes 122 are for wearing that Circular cutter 10 is fixed on associated components.
Cutter tooth 14 is straight tooth-shaped.Cutter tooth 14 is evenly distributed on the periphery of cutter hub 12.Please also refer to Fig. 3 and Fig. 4, each cutter tooth 14 comprises two relative sides 143,144 end face 141,142 relative with two.The side 143,144 of cutter tooth 14 is extended by the respective side 123,124 of cutter hub 12.Specific to structure shown in figure, namely the side 143 of cutter tooth 14 is extended by the side 123 of cutter hub 12, and the side 144 of cutter tooth 14 is extended by the side 124 of cutter hub 12.Two other face of cutter tooth 14 is called the end face 141,142 of cutter tooth 14.In two adjacent cutters tooth 14, an end face 141 of one of them cutter tooth 14 and end face 142 relative tilt of another cutter tooth 14, be also connected in the bottom of cutter tooth 14 simultaneously.
The side 143,144 of each cutter tooth 14 and end face 141,142 intersect at the summit t of this cutter tooth 14.Two end faces 141,142 of each cutter tooth 14 are along being symmetric by the straight line ot of the summit t of corresponding cutter tooth 14 and the mid point o of cutter hub 12 axis L, and two of each cutter tooth 14 sides 143,144 are along being symmetric by the straight line ot of the summit t of corresponding cutter tooth 14 and the mid point o of cutter hub 12 axis l.Wherein the mid point o of axis L refers to the central point on the L of axis, and this central point is equal to the distance of two sides 123,124 of cutter hub 12.The central point of this central point i.e. cutter hub 12, and whole Circular cutter 10 also relatively this central point be symmetric.
The cutter tooth 14 provided due to Circular cutter 10 of the present invention has said structure feature, it has the structure of the central point full symmetric of relative cutter hub 12, there is the point of application single, the effect of uniform force application, can avoid producing burr phenomenon when cutting thin paper, thus can reduce the loss of material, and facilitate the processing of follow-up paper product.Circular cutter 10 of the present invention also can be used for the regularity at the place of cutting require higher, cut the cutting of other thin materials produced without burr, such as film etc.
Further, the angle α between two end faces 141,142 of each cutter tooth 14 is 10-75 degree.Preferably, the angle α between two end faces 141,142 of each cutter tooth 14 is 30 degree.
Further, the angle β between two sides 143,144 of each cutter tooth 14 is 2-9 degree.Preferably, the angle β between two sides 143,144 of each cutter tooth 14 is 4 degree.
Further, the present invention also provides a kind of cutting machine.As shown in Figure 5 and Figure 6, this cutting machine Circular cutter 10 of comprising support 20, driving member 30 and being rotatably connected on driving member 30.This Circular cutter 10 is above-mentioned Circular cutter 10.Circular cutter 10 can be set in the turning cylinder for providing power of driving member 30 by its axis hole 121, and is fixed through fixing hole 122 by fixture.Circular cutter 10 can be followed turning cylinder and rotated together thus.
The driving member that this driving member 30 generally can use for cylinder etc.By the transmission of driving member 30, Circular cutter 10 can with etc. object relative movement to be cut, make Circular cutter 10 enter cut state or idling conditions.This support 20 can be provided with host cavity 200, and what described Circular cutter 10 was at least part of is contained in this host cavity 200.As shown in Figure 5, when needs cut, Circular cutter 10 high-speed rotation, and the object contact that transmission exposed portion cutter tooth 14 to the host cavity 200 passing through driving member 30 is outer and to be cut.Now can control cutting machine to move along direction shown in arrow, to complete the cutting of object, also can control object to be cut and move along direction shown in arrow, to complete the cutting of object.When not needing cutting, whole Circular cutter 10 all can be housed in host cavity 200 by the transmission of driving member 30.
