Background technology

In Apparel Manufacturing, need the button of clothing business is sewed, traditional approach uses and manually button is sewed on clothing, but owing to artificial sewing efficiency is low, when high-volume clothing are produced, it is impossible to adapt to the market demand day by day increased.

Also the equipment using machinery that button is sewed is had in prior art, a kind of button positioner of the use in sewing machine of such as Application No. CN201110194820, including: a bracer, a described bracer is arranged on above sewing machine table, below sewing-machine foot, and a described bracer has the clamping part that can clamp button body portion；Fixed block, described fixed block connects connection strap, what described connection strap can rotate is arranged on sewing machine frame, when button body portion is clamped in described clamping part, button head is pushed against on a described bracer by described fixed block, and the pin hole being opened in button body portion is positioned at the underface of sewing machine needle.The present invention overcomes traditional handicraft when sewing band target button by positioner, it is impossible to stable fixes button, its simple in construction, easy and simple to handle, can effectively improve work efficiency during sewing.

This patent is disadvantageous in that, one end of connection strap is connected in rotating shaft, when button is fixed complete by this fixing device, the vibration that is easily located in the perforation of button due to eedle when sewing machine sews for button and cause connection strap to produce displacement, thus eedle is likely directly inserted on button the phenomenon causing eedle to fracture.

Utility model content

The purpose of this utility model is to provide and a kind of increase chamber fixing device fixation and reduce the sewing device for button that button displacement causes eedle to fracture and the seam deduction using this device.

Above-mentioned technical purpose of the present utility model has the technical scheme that

A kind of sewing device for button, the base extended including sewing machine and sewing machine lower end, sewing machine front end is provided with the fixing device for fixing button, and described fixing device includes fixed block, connecting rod and rotating shaft, and described rotating shaft is provided with the torsion spring pushing down button for drive connection bar.

By this setting, utilize the elastic-restoring force of torsion spring, button can be fixed under the effect of this elastic-restoring force by connecting rod, thus the phenomenon that during avoiding making to sew due to the vibrations of eedle drive sewing machine, fixed block is subjected to displacement, decrease the probability that eedle fractures.

Of the present utility model being further arranged to: being relatively set with side plate on the sidewall of described rotating shaft, connecting rod is set on side plate, and rotating shaft top is provided with the top cover for withstanding connecting rod, connecting rod is provided with driving lever relative to rotating shaft away from one end of fixed block.

By this setting, utilizing lever principle, driving lever can facilitate the rotation for connecting rod, reduces and needs, owing to torsion spring exists, the strength additionally paid；Connecting rod is set on side plate and enables to connecting rod and can rotate for the center of circle with rotating shaft, adds stability when connecting rod rotates, thus reduces the displacement that fixed block produces due to vibration, decreases the probability that eedle fractures.

Of the present utility model it is further arranged to: on base, be provided with pendulous device, described pendulous device includes oscillating deck, described fixing device is arranged on one end of oscillating deck, montant it is equipped with on oscillating deck, described montant is fixed on base, and oscillating deck is provided with driving structure relative to the other end of fixing device.

By this setting, oscillating deck swings with montant for the center of circle, thus during button is sewed by eedle, button can be driven and swing, it is achieved eedle be through the clasp of button back and forth and by button sewing purpose on clothing.

Of the present utility model being further arranged to: described driving structure includes being arranged on the cam of oscillating deck side, described cam is driven by the motor being arranged on base, and oscillating deck opposite side is provided with the returning spring for replying oscillating deck.

Conflicted in oscillating deck one end by cam, it is achieved the effect that oscillating deck is released, utilize again the elastic force of returning spring after the big end of cam turns over by oscillating deck forced back, so circulation so that oscillating deck is capable of the effect swung.

Of the present utility model it is further arranged to: fixed block is provided with the conflict head for conflicting with button towards one end of button, and conflict head is provided with the groove suitable with the button of button.

By this setting, button can penetrate in groove, thus adds button in the stability worn by eedle, it is to avoid the situation that button produces displacement and causes eedle to fracture.

Of the present utility model it is further arranged to: on described fixed block, be provided with perforating, the post that wears conflict head being provided with in penetrating perforating, perforating bottom surface is provided with the colloid layer for fixing conflict head.

By fixed block is arranged with conflict head split, it is possible to be convenient for changing conflict head, for difference for wearing in post is located in perforating and being bonded by colloid layer, add the connective stability of conflict head and fixed block.

Of the present utility model being further arranged to: oscillating deck front end is provided with presser feet, and presser feet offers U-lag, what presser feet offered towards the side of button that the clasp for button penetrates penetrates groove.

By this setting, it is possible to make clasp to wear in presser feet, fix so that clasp can be threaded into groove, add button by the stability after fixing, reduce button displacement and cause eedle to be inserted on clasp fractureing the situation of eedle.

Of the present utility model it is further arranged to: the lower surface of described presser feet is provided with tangent line blade.

By this setting, it is possible to making button after sewing, staff can be by tangent line blade by being initially switched off after sewing, it is to avoid cuts off with shears and affects work efficiency.

Of the present utility model it is further arranged to: described tangent line blade takes the shape of the letter U, and the cutting edge of tangent line blade is arranged at Inner arc.

By this setting, cutting edge is arranged at the Inner arc of tangent line blade of U-shaped, it is possible to make this tangent line blade it can be avoided that contact with the hands of staff or clothing and cause staff injured or phenomenon that clothing are impaired.

Another object of the present utility model is to provide a kind of seam deduction with sewing device for button.

In sum, this utility model has the advantages that the torsion spring being arranged in rotating shaft by utilization, button can be propped up under the effect of the elastic-restoring force of torsion spring by connecting rod, thus reduce the phenomenon making fixed block during sewing be subjected to displacement owing to eedle drives the vibrations of sewing machine, decrease the probability that eedle fractures.
