Description

The supporting arm device of seat formula insole stiching machine

Technical field

The present invention relates to the supporting arm device of a kind of formula insole stiching machine, belong to for the stitching machinery of making the parallel three-way of sole and upper of a shoe or broad two lines.

Background technology

At present, sole and upper of a shoe for sport footwear, playshoes etc. are sewed up processing, mainly select for use the special-purpose seat of shoemaking formula insole stiching machine to finish, but traditional seat formula insole stiching machine once can only be made a stitching, making two or three stitchings needs twice or three operations, and multi-pass operation is parallel because of not reaching stitching, neither attractive in appearancely loses time again.Dongguan, Guangdong one is taken now a kind of computerized emboridering machine shuttle of establishing out of in supporting arm, two parallel pins are set under the shank, though this kind machine can stitch out two upper threads that upper thread is parallel broad, or also can make three lines through changing shank, but this kind machine has two obvious defects: the one, and the shuttle body is located at the inferoanterior (with respect to the operator) of eedle and presser feet, be after shoes put supporting arm, presser feet is pushed down shoes on needle plate, the contact size of presser feet and needle plate has only the 4-5 millimeter, so the feeding instability; The 2nd, rotate through many grades of gears in the supporting arm head (being the ox horn head), not only volume can be increased, and the accumulation gap can be increased, it is unreliable to cause transmission.And the another kind of special-purpose seat formula insole stiching machine that can make parallel stitching can be made two parallel upper threads, but a shortcoming is arranged equally, and promptly the maximum spacing of two upper threads is very little, more not talkatively will make three parallel upper threads.

Summary of the invention

The objective of the invention is to provide a kind of can keep operation smooth when sewing, and feeding is stable, and the pin sign indicating number is even; Simultaneously, compact conformation, ox horn head volume are less, flexible operation, installation and easy to adjust, reliable transmission, and can make the supporting arm device of seat formula insole stiching machine of the suture of three parallel or two broads.

The objective of the invention is to reach like this, the supporting arm device of a kind of formula insole stiching machine comprises an arm seat, and the axial middle hub setting of this arm seat has a gear shaft; One is fixed on the supporting arm seat on the arm seat, has the supporting arm body, supporting arm battered leg and supporting arm spindle nose, offering through hole in the vertical centre of supporting arm body is vertical core, top has the groove that communicates with vertical core, the supporting arm battered leg is arranged on the horizontal of supporting arm body upper end, axial centre at the supporting arm battered leg offers inclined hole, inclined hole communicates with groove, the supporting arm spindle nose is arranged on the bottom of supporting arm body, axial centre at the supporting arm spindle nose offers gear cavity, gear cavity communicates with vertical core, the spindle nose of described gear shaft probes in the gear cavity, and is fixed with gear with curved teeth on spindle nose; One first, place vertical core, first upper end probe in the groove and be fixed with gear with curved teeth in the end, upper end, first lower end probes in the gear cavity and in the end, lower end and is fixed with gear with curved teeth; One is fixed on the adapter sleeve on the supporting arm battered leg that supports arm seat, offers through hole in the axial centre of adapter sleeve, and through hole communicates with groove; One is fixed on the ox horn head on the adapter sleeve, is formed with at the front end of ox horn head that shuttle chamber, middle part are formed with the bevel gear chamber, the rear end is the shank that is used to install adapter sleeve; One second, place the through hole of adapter sleeve, an end of second to probe in the groove and on spindle nose, be fixed with gear with curved teeth, second the other end probes in the bevel gear chamber at ox head angle and be fixed with bevel gear on spindle nose; One is used for the ox horn lid fixing with the ox horn head, is formed with shuttle gear nest, bidentate wheel nest in it, is provided with a bearing in the bottom of shuttle gear nest; One shuttle gear places in the described shuttle gear nest, offers flat hole in the middle of it is axial; The a pair of gear is pivotally connected in the bidentate wheel nest, has straight-tooth and awl tooth, and wherein straight-tooth is meshed with the shuttle gear, bores tooth and is meshed with bevel gear in the bevel gear chamber; One is arranged on the shuttle in the shuttle chamber, comprises outer shuttle and Nei Suo, and Nei Suo rotates in the shuttle outside, is provided with minute hand groove and breach on interior shuttle, and shuttle is provided with homalocephalus and is used to collude the spur of line outside, and homalocephalus cooperates with flat hole on the shuttle gear after passing a bearing; One screw is fixed with the homalocephalus of shuttle behind the bearing that passes pad, ox horn lid bottom successively; Bobbin case is installed in Nei Suonei; One is fixed on the needle plate that ox horn covers the end, offers the needle tray and the shuttle retaining head that can pass through for three parallel eedles on needle plate, the position of needle tray be positioned at described shuttle directly over, in shuttle retaining head then extends to downwards in the breach of shuttle; One capping, cap seal is at the accent of the gear cavity of described supporting arm seat; One shrouding, cap seal is at the notch of the groove of described supporting arm seat.

In a specific embodiment of the present invention, described first two ends are installed and are used axle sleeve, and first middle part is equipped with collar, and described axle sleeve and collar are arranged in described vertical core.

In another specific embodiment of the present invention, described second two ends are equipped with axle sleeve.

The present invention is because after adopting said structure, the beneficial effect that has: at first, because the needle tray size in needle plate and the shuttle on the shuttle is big, and the direction of rotation of shuttle is parallel with three eedles, shuttle can catch on three sutures on the eedle simultaneously, so can make three parallel upper threads or two parallel upper threads of broad; Secondly, shuttle is arranged at the following rear (with respect to the operator) of eedle and presser feet, and the flank of tooth of presser feet bottom is positioned at the top of needle plate fully, and promptly presser feet and needle plate contact-making surface reach maximum, so after presser feet was pushed down shoes, the feeding of presser feet was stable, the pin sign indicating number is even; Again, compared with the prior art, lacked a transition gear in the transmission mechanism, so compact conformation, little, the reliable transmission in gap, and the volume of ox horn head also suitably reduces.
