Description

Buttonhole sewing machine cutter
Technical field
The present invention relates to a kind of Buttonhole sewing machine, this Buttonhole sewing machine is furnished with a cutter, this device has a cutting knife and cutter pillow, place respectively the top of institute's tailoring cloth and below, after finishing the making an of buttonhole, cutting knife and cutter pillow will cut out buttonhole in the centre of the buttonhole stitching of making, and also can cut first buttonhole before making and make, refer in particular to a kind of Buttonhole sewing machine cutter.
Background technology
At present, the buttonhole size that some Buttonhole sewing machines cut out on the market is all changed as required different cutter pillows or cutting knife and is realized, so every machine all is furnished with the cutter pillow of sizes specification.For computer buttonhole keyhole machine, owing to increased the movement of cutter pillow and mop board, so can cut out the buttonhole of various sizes.The movement of cutter pillow is generally by an air cylinder driven, had artificially and obtained seeing eye (buttonhole of Gong viewing and admiring), two kinds of cutting knifes on the position of cutting knife, have been placed side by side, one is the buttonhole of cutting aforementioned various sizes, another then is used for cutting sees eye, and these two cutting knifes also are to use as required an air cylinder driven conversion.
Chinese patent once disclosed a kind of " cutting mechanism of computer buttonhole locking machine " (China, publication number CN2858703, open day on January 17th, 2007), the automatically controlled case of micro computer is communicated with the dibit electromagnet, on the dibit electromagnet sliding axle cutting knife link is housed fixedly, the electromagnetic cutting knife link is hinged by cutter driving connecting rod and cutter driving arm one end, the cutter driving arm is the triangular form curved boom, in the axis hole of cutter driving arm middle part axle is housed, the other end is connected with another cutter driving connecting rod by hinge axis, another cutter driving connecting rod is connected with the cutter driving connecting axle, drive connecting axle one termination guide runner, guide runner places in the cutter bar guide plate chute, drives the connecting axle other end cutter driving pedestal fixedly is housed, and the bottom fixedly is housed with the cutter driving axle of blade on the cutter driving pedestal.The cutting knife motion is independent, reliable, steady, and flush shear force is controlled, and is easy to operate.But it can not be accomplished in more tool changing pillow and cutting knife situation, just can realize cutting the buttonhole of various forms and size.
Summary of the invention
The object of the present invention is to provide a kind of Buttonhole sewing machine cutter, it more just can realize the buttonhole of cutting various forms and size in tool changing pillow and the cutting knife situation.
For achieving the above object, the solution that the present invention takes is: a kind of Buttonhole sewing machine cutter, it comprises cutting knife, cutter pillow and cutter mechanism driver, one end of cutter mechanism driver is hinged on the housing, the other end is articulated on the fork, and the telescopic band movable pendulum bar of cutter mechanism driver swings around axle O, drives traveller by first connecting rod and moves up and down, the cutter pillow and the cutter pillow driver that are fixed on the traveller lower end move up and down cutter pillow and cutting knife butt thereupon; The blade of cutting knife is divided into L1 and L2 two parts, and L1 partly is straight eye cutting position, and partly for seeing the eye cutting position, L1+L2 partly is the phoenix eyes cutting position to L2; Cutter pillow driver comprises pedestal, Composite cylinder, Composite cylinder is made of composite cylinder, large piston and valve piston, have the sliding tray that in groove, horizontally slips for the cutter pillow on pedestal one end, composite cylinder is fixed on the other end of pedestal, one large piston and valve piston arranged in the composite cylinder, valve piston by two end plug shutoff in the inner chamber of large piston, the two-port of composite cylinder is blocked by end, the rod end external part of valve piston is stifled, second connecting rod is connected a rod end of valve piston with the cutter pillow, two rod ends of valve piston connect respectively left joint and right connector.
This kind Buttonhole sewing machine cutter, the cutter pillow just cuts out buttonhole with the cutting knife butt, and the form of the buttonhole that cuts out has three kinds: phoenix eyes, straight eye and sight eye; The blade of cutting knife is divided into L1 and L2 two parts, and L1 partly is straight eye cutting position, and partly for seeing the eye cutting position, L1+L2 partly is the phoenix eyes cutting position to L2, so, as long as just make the cutter pillow produce the different holes of cutting from a part butt of cutting knife cutting edge.The air inlet at valve piston two ends and exhaust be by left joint, right connector, enters the valve piston both sides by valve piston again.When right-hand member air inlet, the left end exhaust of composite cylinder, left joint air inlet, during the right connector exhaust, small piston rod promotes cutter by second connecting rod and rests the head on to cutting knife blade phoenix eyes cutting position; When right-hand member air inlet, the left end exhaust of composite cylinder, left joint exhaust, during the right connector air inlet, cutter pillow at this moment is in the straight eye of cutting knife blade cutting position; When left end air inlet, the right-hand member exhaust of composite cylinder, left joint air inlet, during the right connector exhaust, cutter pillow at this moment is in the cutting knife blade and sees the eye cutting position.Therefore, the different buttonhole cutting form that this kind Buttonhole sewing machine cutter utilizes the cutter pillow to obtain from the different contact position of cutting knife, and the driver that drives cutter pillow diverse location is comprised of a Composite cylinder, this Composite cylinder is so that the cutter pillow has three kinds of contact positions with cutting knife, thereby form the buttonhole of phoenix eyes, straight eye, three kinds of citation forms of sight eye, add the work feed supporting plate and move different sizes, just can cut out the buttonhole of different size, can more just can realize the buttonhole of cutting various forms and size in tool changing pillow and the cutting knife situation.
