Abstract
The utility model discloses a dedicated cutting saw blade for a preservative film/paper/an adhesive tape/aluminum foil. The whole structure of the dedicated cutting saw blade is of a bow shape, and three groups of saw teeth are distributed on three edges of the inner side of the bow-shaped structure. In the cutting process of the preservative film/the paper/the adhesive tape/the aluminum foil, the saw teeth on an inclined edge can easily cut up the edge of materials to be cut to form cuts, and with that, the cuts can be enlarged along the saw teeth of a straight edge until the materials are completely cut. The bow-shaped structure of the dedicated cutting saw is symmetrical so as to adapt to the using habit of people with a left hand or a right hand.
Description
Technical field:
The utility model relates to the special-purpose cutting saw blade of a kind of preservative film/paper/adhesive tape/aluminium foil, is applicable to preservative film, adhesive tape, paper, the flexible thin-film materials' such as aluminium foil even garment material cutting.
Technical background:
Huge numbers of families have been goed deep in the use of preservative film, but in our use procedure, have a bit very unsatisfactory, and that is exactly that preservative film is not easy tear fracture very much; Even if perhaps tear fracture also is difficult to the section that keeps neat.Employing is lancinated or the mode of scissor cut, has increased again certain trouble degree, so that convenience reduces.
The preservative film cutting saw blade that generally uses in the market designs as linear pattern, and result of use is not good, is because do not fully take into account the characteristic of this class material of preservative film itself.Preservative film is soft, and is yielding, and has larger tensile elasticity.In the process of using the cutting of linear pattern saw blade, the distortion because preservative film itself is stretched, cause whole preservative film to be forced on most of sawtooth of linear pattern saw blade, stressed almost by average being distributed on each sawtooth, thereby do not form an effective cut point, so also be difficult to form effective otch.Another key property of preservative film is exactly, on existing otch, be easy to along one party to sawtooth or blade be torn, so effectively otch is the key of cutting preservative film.
Another kind of preservative film saw blade is the design of " V " shape on the market, can form in theory effective cut point and effective otch, but in use still has defective.At first, its effective cut point is in the center of whole preservative film, but this position also is the position of preservative film stretcher strain amount maximum.In order to form effective otch, best scheme reduces the number of degrees at " V " angle exactly, makes " V " angle become sharper.Thus, must need to increase the height of whole " V " shape structure, but this point is also so that the reduction of the practical significance of production and use procedure.Secondly, easily damage or bending of cusp place crown in " V " shape structure, thereby lose its effective cut point, cause cutting efficiency to descend.In addition, the saw blade of " V " shape structure in use has suitable danger, especially for the very heavy child of curiosity.
The utility model content:
In sum, for solving the many disadvantages of present preservative film saw blade in production and use procedure, the utility model proposes a kind of brand-new solution, the i.e. saw blade of " arc " structure.This saw blade good cutting effect, easy to use, and be suitable for large-scale production.
Concrete technical scheme is as follows:
Whole saw blade is bow-shaped structural, three groups of sawtooth groups are distributed on three limits of bow-shaped structural inboard: wherein one group of sawtooth is evenly distributed on the straight flange at whole saw blade middle part, on other two groups of two hypotenuses that are evenly distributed on whole saw blade two ends (seeing Fig. 1), saw blade has locating hole group (seeing Fig. 5).
The straight flange at the hypotenuse at saw blade two ends and saw blade middle part is certain angle, and namely ∠ 1, and angular range is 0 to 90 ° (seeing Fig. 1).
From the projection of saw blade top, the projection line length of the single hypotenuse of saw blade and the projection line length of whole saw blade are certain proportionate relationship, and scope is 0 to 0.5 (seeing Fig. 2).
Saw blade locating hole group is comprised of a circular hole and two waist-shaped holes, can set one or two group of locating hole group (seeing Fig. 5) according to the saw blade concrete shape.
Under specific circumstances, the bow-shaped structural deformable of whole saw blade is circular arc (seeing Fig. 3) or sickleshaped (seeing Fig. 4).
Whole saw blade designs for symmetric form, uses preference to meet right-hand men different among the crowd.
The material of saw blade can be metal or nonmetal.
Description of drawings:
Description of drawings is only being illustrated as purpose, and limits never in any form scope of the present utility model.
Fig. 1 is top view and the partial enlarged drawing of saw blade.
Fig. 2 is the ratio schematic diagram of saw blade hypotenuse projection line length and whole saw blade projection line length.
Fig. 3 is the structural representation that saw blade is deformed into circular arc.
Fig. 4 is that saw blade is deformed into sickle-shaped structural representation.
Fig. 5 is the structural representation of locating hole group on the saw blade.
Fig. 6 is saw blade cutting process schematic diagram.
The specific embodiment:
In the process of cutting preservative film or other flexible materials, the sawtooth on the hypotenuse can at first touch the edge (seeing Fig. 6) of preservative film.We describe the specific implementation process of cutting take an end as example.As everyone knows, the easiest being torn out in film material edge is because the stretcher strain limit at its edge is far smaller than the stretcher strain limit of the center.When the crown on the hypotenuse touches the edge of preservative film, the wedge angle ∠ 2 of particular design almost with the preservative film plane in vertical state, only need less relative motion, crown can be worn out preservative film, forms an effective cut point.The preservative film at cut point place continues to move along the sawtooth group, and effectively cut point is then constantly amplified, until the edge of preservative film is cut open, forms an effective otch; And then, otch can continue along the sawtooth of straight flange to enlarge, until cut off fully.
Triangle locating hole group can firmly be positioned at saw blade on the tool using, prevents that saw blade from skew or come off (seeing Fig. 5) occuring.
