A kind of button hole open-celled structure
Art
The present invention relates to clothes making manufacturing apparatus field, especially, is a kind of perforate machinery of button hole.
Background technology
Button is exactly fastener connected for the both sides hem on clothes.Initial effect is used to the left front of connecting clothing, now develops into gradually and have more artistry and ornamental except its original function of maintenance, namely personalized.Good button it your clothes can be made more perfect, play the effect of " crucial touch ", play certain beauty function.Especially there is the stud of a lot of colorfulness in women clothing.Specifically: connecting clothing mind be button, namely our existing button often said for another wind coat band junction button etc. be the disconnected hem then for buckle, but we get used to the two to unite two into one, and are referred to as button.
Button hole is sewed to clothes relevant position by special sewing machine for buttonhole, the region that sewing surrounds re-uses manually to be cut off, during due to manual operation, workman's both hands can only operate cutting implement and fixing clothes simultaneously, therefore shear and there is very large uncertainty, be easy to cause shearing mistake, cause clothes to scrap.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of button hole open-celled structure, this button hole open-celled structure can carry out the rear incision in accurately location to the button hole of button.
The technical solution adopted for the present invention to solve the technical problems is:
This button hole open-celled structure comprises two fixed axis, the homonymy of described fixed axis line is provided with the pilot pin perpendicular to line, the hinged semicircular arc cutter of difference on described fixed axis, described arc cutter is symmetrical arranged and synchronous backward rotates, and the distance between described fixed axis equals two times of described arc cutter straight length.
As preferably, the two ends of described locating shaft line are provided with the deflector roll pair that clamping needs perforate clothing, and described deflector roll is contrary to rotation direction.
As preferably, the point of a knife of two described arc cuttves adapts when contacting the new independent point of a knife of formation one.
As preferably, described independent point of a knife and described pilot pin are on the same line.
The invention has the advantages that:
Utilize the button hole on the clothing of described pilot pin location, utilize described arc cutter to cut clothing along pilot pin line simultaneously, make the shearing of button hole precisely quick.
Accompanying drawing explanation
Fig. 1 is the structural representation of this button hole open-celled structure.
Fig. 2 is the schematic diagram under this button hole open-celled structure shearing condition.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Consult Fig. 1, in the present embodiment, this button hole open-celled structure comprises two fixed axis 200, the homonymy of described fixed axis 200 line is provided with the pilot pin 300 perpendicular to line, the hinged semicircular arc cutter 400 of difference on described fixed axis 200, described arc cutter 400 is symmetrical arranged and synchronous backward rotates, and the distance between described fixed axis 200 equals two times of described arc cutter 400 straight length.
In Fig. 1 and Fig. 2, need perforate clothing 100 to be sewed with the suture 110 surrounding button hole.
Above-mentioned button hole open-celled structure, the two ends of described locating shaft 200 line are provided with clamping needs the deflector roll of perforate clothing 100 to 500, described deflector roll is contrary to 500 rotation directions, described deflector roll is convenient to the tension to needing perforate clothing 100 to 500, make clothing 100 when being subject to arc cutter 400 and cutting, keep flat state.
Above-mentioned button hole open-celled structure, the point of a knife 410 of two described arc cuttves 400 adapts when contacting the new independent point of a knife of formation one, described independent point of a knife can independently puncture described clothing 100, make two described arc cuttves 400 all with this point for cut point, prevent two cut point cause cut incomplete consequence.
Above-mentioned button hole open-celled structure, described independent point of a knife and described pilot pin 300 on the same line, make described independent point of a knife also participate in the work of locating button mouth, make the more accurate positioning of button hole.
The operation principle of above-mentioned button hole open-celled structure and method:
Consult Fig. 1, suture 110 on clothing 100 is surrounded two ends correspondence inside button hole and insert described pilot pin 300, consult Fig. 2, drive arc cutter 400, described arc cutter 400 is cut to two lateral incisions at the center of button hole, until button hole cuts.
Describedly be only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included in protection scope of the present invention.
