Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view choosing dermatotome in the utility model;
In figure, choose dermatotome 100, matrix 1, bottom 11, installing hole 12, penetration portions 2, installation portion 3, tip 21, cutting edge 22, cutting body 23, acute angle a.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in fig. 1, a kind of roll web described in the utility model is with choosing dermatotome 100, comprise matrix 1 and be located at matrix 1 side for open paper roll penetration portions 2, be located at matrix 1 opposite side for installing the installation portion 3 of matrix 1, the tip 21, most advanced and sophisticated 21 that described penetration portions 2 comprises for interting is extended with cutting edge 22 on matrix 1, and described cutting edge 22 extends to form cutting body 23 to the two sides on installation portion 3 top; At least there is the effect that not only can break leatheroid but also not damage the surface of choosing paper device last volume coil paper.
The technical scheme of the application, changing in prior art utilizes blade to carry out the mode cut, the mode backing down paper roll is interted by the tip place choosing dermatotome 100, the leatheroid of circumferencial direction or paper tear are opened, a cutting edge 22 is utilized to extend to form cutting body 23 to the two sides on installation portion 3 top, make full use of an oblique slope extended to form, the most advanced and sophisticated paper roll to circumferencial direction gradually moves, and realizes opening of circumferencial direction paper roll and splits.
What the cutting edge 22 making full use of inclination carried out upwardly formula tears paper or leatheroid, fundamentally solve and utilize blade to carry out the mode cut, avoid the danger using cutter to bring, and without grinding cutting edge 22, can use always, avoid utilizing blade to carry out cutting the mode needing grinding.
As shown in fig. 1, a kind of roll web is with choosing dermatotome 100, comprise matrix 1 for both sides, bottom be the trapezoidal of right angle, two vertical right-angle sides connect as one with the penetration portions 2 of front end (left end as shown in Figure 1) respectively and the installation portion 3 of rear end (right-hand member as shown in Figure 1) connects as one, the right-hand member that described penetration portions 2 is fixedly connected on the left end of matrix 1, installation portion 3 is fixedly connected on matrix 1, matrix 1, penetration portions 2, installation portion 3 three form a set square structure jointly, adopt metallic plate to make and have higher service life and wearability.
Also plastic plate or plank be can adopt, selection and making are convenient to.The sheet material that other hard materials such as carbon fiber board are formed can meet instructions for use.
It can be the right angled triangle plate body of 30 degree for acute angle a that matrix 1, penetration portions 2, installation portion 3 three form a set square structure jointly, the hypotenuse part being conducive to right angled triangle plate body top cuts, by cutting edge 22 pairs of paper of hypotenuse part or vertically backing down of leatheroid, realize tearing.
And be located at matrix 1 side for opening the penetration portions 2 of paper roll, penetration portions 2 has sharp parts and oblique cuts part, utilize sharp parts under the leatheroid or paper of the axis insertion roll web of roll web, the circumference being axially perpendicular to roll web of roll web, the penetration portions 2 that leatheroid in roll web circumference or paper are axially inserted into tears apart, and oblique cutting edge 22 is conducive to paper or the leatheroid that penetration portions 2 tears apart web surfaces faster.
Be located at matrix 1 opposite side for installing the installation portion 3 of matrix 1, installation portion 3 is for being connected to the trapezoidal plate of matrix 1 right side, vertical edges on the right side of installation portion 3 is perpendicular to bottom 11, by installation portion 3, cutting edge 22 is supported the oblique cutting edge 22 of formation, cutting edge 22 extends to form the cutting body 23 of prism shapes to the two sides on installation portion 3 top, cutting edge 22 is a limit of triangular prism upper end, utilizes the limit of triangular prism upper end to carry out cutting and be conducive to cutting edge 22 and better paper or leatheroid torn apart.
Described penetration portions 2 tip 21, most advanced and sophisticated 21 comprised for interting can be that leg-of-mutton acute angle is most advanced and sophisticated, also can be the structure that pointed rivet head etc. is sharp-pointed.
Most advanced and sophisticated 21 extend to form cutting edge 22 to matrix 1 top edge, and described cutting edge 22 extends to form cutting body 23 to the two sides on installation portion 3 top.To utilize on cutting body 23 pairs of cutting edges 22 stressed decomposes, thus the stressed bottom surface of changing cutting body 23 into making cutting edge 22 limit or a line is stressed, reduces intensity when cutting edge 22 tears paper.
Decomposed in matrix 1 and installation portion 3 by pressure by the bottom surface of cutting body 23, ensure overall stress equalization, interstructural stability is higher, not frangibility.
The base of the lower edge of described penetration portions 2 and the lower edge of installation portion 3 and matrix 1 forms level and smooth bottom 11 jointly.Bottom 11 is a level and smooth plane, is contacted with paper or leatheroid by plane, avoids bottom 11 to cut paper or the leatheroid of choosing dermatotome 100 bottom, realizes the protection treating processing paper or leatheroid, avoids waste.
Described penetration portions 2 is acute triangle, adopts simple structure, is convenient to processing and manufacturing.
Acute angle a in described acute triangle is in the scope of 5 degree to 45 degree.Acute angle in acute triangle tapers off to a point, the tip of the less formation of angle is more sharp-pointed just can insert in roll web faster, be conducive to realization to cut, but it is too sharp-pointed that acute angle crosses apiculus, is also more prone to fracture, therefore adopt the tip that the acute angle a in acute triangle is formed in the scope of 5 degree to 45 degree, there is good effect, when wherein acute angle is 30 degree, the tip of formation is comparatively stable, and intensity is higher.
Described matrix 1 top is provided with the installing hole 12 for fixedly mounting portion 3.Mounting handle or be connected with support in installing hole 12, is conducive to operating choosing dermatotome 100.
Be provided with at least one installing hole 12 in described installation portion 3, when installing hole 12 is a screw, the rod-shaped scaffolds such as screw rod can be installed.
Described installing hole 12 is polygonal through hole.A circular installing hole 12 is set, can rotates when choosing dermatotome 100 and being stressed, therefore adopt polygonal column, be plugged in polygonal through hole, thus choosing of avoiding an installing hole 12 to install dermatotome 100 is stressed to be rotated.
Run through in described installation portion 3 and have two foursquare installing holes 12.Two foursquare installing holes 12 are adopted directly to be connected to by installation portion 3 in two cuboids, not only accurate positioning but also can not rotate.
By foregoing description, those skilled in the art can implement.
Above content described in this description is only to the explanation of the utility model structure example; And the utility model parts title of getting also can be different, all equivalences of doing according to structure, feature and the principle described in the utility model inventional idea or simple change, be included in the protection domain of the utility model patent.
