Abstract
The utility model aims at the problem that a straight blade of a straight knife of a conventional fabric cutting machine has over large damping in cutting process and provides a straight knife of a fabric cutting machine, which effectively overcomes cutting damping and comprises a body, a jaw, blades and notches. The jaw is arranged on the tail portion of the body and connected with the fabric cutting machine, the blades are disposed on one side and at the front end of the body, one side of the body with blades is provided with notches for overcoming cutting damping, one side of the body with the blades is provided with pluralities of notches which are arranged at the same interval, and the blades are disposed at the notches. Further, one side face of the body is provided with an air deflector groove. The straight knife of a fabric cutting machine has the advantages that the notches on the blade overcome the cutting damping and effectively prevent fabric from closely adhering to the straight knife so as to impend cutting movement of the straight knife, the equidistant arrangement of the notches further improves effect of overcoming the cutting damping, and the air deflector groove disposed on the cutting side of the body effectively prevents the fabric from closely adhering to the straight knife.
Description
Technical field
The utility model relates to a kind of sewing machine accessory, specifically is meant the straight knife that a kind of fabric cutter that can effectively overcome the cloth damping is used.
Background technology
The operation principle of straight knife type fabric cutter is that to be installed in straight knife on the fabric cutter by driven by motor up and down to reach the effect of cutting multilayer cloth, existing fabric cutter straight knife comprises blade, the blade afterbody is provided with the jaw that is connected with fabric cutter, blade one side and front end have blade, blade is shape linearly, the problem that this fabric cutter straight knife exists is: in cutting the process of cloth, cloth closely contacts the generation negative pressure with blade, motion to blade produces very big damping, the motion of obstruction straight knife, influence cuts effect, and straight knife weares and teares easily.
Summary of the invention
The utility model cuts the excessive problem of damping in the process at existing fabric cutter straight knife linear blade existence, and a kind of fabric cutter straight knife that cuts damping that effectively overcomes is provided.
The technical solution adopted in the utility model is:
A kind of fabric cutter straight knife comprises blade, and described blade afterbody is established the jaw that is connected with fabric cutter, and blade one side and front end have blade, and the side that described blade has blade is provided with the breach that overcomes the fabric dividing damping.
Further, the side that described blade has blade has a plurality of breach, and each breach is equidistantly arranged.
As preferably, described breach is triangular in shape.
Preferred as another kind, described breach is curved.
Further, described indentation, there has cutting edge.
Further, described blade side also is provided with the air conducting groove.
Further, described blade two sides are equipped with the air conducting groove.
Further, described air conducting groove has a plurality of, and is equidistantly uniform.
Further, described air conducting groove is vertical with the blade side, the cross section indention.
The beneficial effects of the utility model are: be provided for overcoming the breach that cuts damping on the blade, thereby prevent that effectively cloth is close to straight knife and hinders straight knife and cut motion; A plurality of breach are equidistantly arranged, and further improve to overcome the effect that cuts damping; Blade cuts side and also is provided with the air conducting groove, prevents that effectively cloth and straight knife from fitting tightly; The air conducting groove is vertical with the blade side, and the cross section indention is rational in infrastructure, cuts smooth and easy.
Description of drawings
Fig. 1 is the structural representation of existing guillotine straight knife;
Fig. 2 is the structural representation of the utility model embodiment one;
Fig. 3 is the structural representation of the utility model embodiment two;
Fig. 4 is the part perspective view of the utility model embodiment two.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
With reference to Fig. 1, existing fabric cutter straight knife comprises blade 1, and blade 1 afterbody 11 is provided with the jaw that is connected with fabric cutter, and front end 12 has blade 121, and the side that is used to cut cloth has blade 2, is used to cut blade 2 shape linearly on the side of cloth.
The utility model is improvements over the prior art, and its improvements are:
Embodiment one
With reference to Fig. 2, the blade 2 of blade side has and is used to overcome the breach 3 that cuts damping.Continue to overcome in the process that moves up and down and cut damping in order effectively to overcome blade 1, the blade 2 that is used to cut on the side of cloth has a plurality of breach 3, and each breach is equidistantly arranged.The shape of breach 3 can be triangle, also can be arc, certainly, also can be effectively to overcome other shape that cuts damping.Smooth and easy in order to guarantee to cut, breach 3 places have sharp cutting edge 4.
Embodiment two
With reference to Fig. 3, the difference of present embodiment and embodiment one is: on the basis of embodiment one, blade also is provided with air conducting groove 5 on 1 side, effectively avoids cloth to fit tightly with blade 1 in the process of cutting.Overcome the effect that cuts damping in order further to improve, the blade two sides are equipped with air conducting groove 5.Air conducting groove 4 has a plurality of, and is equidistantly uniform.With reference to shown in Figure 4, in the present embodiment, air conducting groove 5 is vertical with blade 1 side, and the cross section indention can effectively prevent cloth and blade 1 applying, guarantees to cut smooth and easy again.Certainly, the cross sectional shape of air conducting groove 5 also can be other shape.
Should be pointed out that the utility model is not limited to the structure of above embodiment, on the basis of utility model inventive concept, those skilled in the art can also make corresponding distortion, and these distortion also fall in the protection domain of the present utility model.
