Abstract
The invention discloses a crinkle sewing structure. A pressing sheet for compacting the cloth strips for crinkling on a feed dog is arranged in front of a frame needle, the front end of a presser foot presses shell fabric on the pressing sheet, and the rear end of the presser foot presses the shell fabric and the cloth strips for crinkling which are sewed together on the feed dog. The invention also discloses a crinkle self-guiding device, comprising the pressing sheet which is fixed on a pressing sheet shaft. The pressing sheet shaft is rotatably arranged on a support and is parallel to a sewing machine panel, and a rotating seat is fixed in the circumferential direction of the pressing sheet shaft and is connected with the support through an elastic mechanism, wherein the support can be installed on the sewing machine panel, and the elastic mechanism enables the pressing sheet which is fixed in the circumferential direction of the pressing sheet shaft like the rotating seat to have a trend of rotating through the rotating seat. By using the technical scheme, the crinkles can be sewed in one step in the sewing process of the sewing machine, and manpower is not needed for making the crinkles, thereby the processing efficiency is greatly improved, and the crinkles are uniform and attractive.
Description
Technical field
The invention belongs to the stitching process field, particularly relate to a kind of being installed in and on lining, to make the wrinkle self-conductance device that contracts that the wrinkle that contracts is decorated cloth on the Sewing machines.
Background technology
For more attractive in appearance, generally can on clothings such as underwear or nightwear, make decoration cloth (stringy selvedge or lace), in the prior art with the wrinkle effect that contracts; Generally be in the time will decorating cloth through Sewing machines and be sewn on the lining, carry out wrinkle by manual work, promptly the operative employee carries out wrinkle to decorating cloth earlier; It is made on lining, like this, working (machining) efficiency is low first again; Second the wrinkle that contracts is inhomogeneous, and crudy is unstable.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of wrinkle sewing structure that contracts, can be in the stitching sewing machine process the disposable completion wrinkle that contracts, do not need manual work to carry out wrinkle, improved working (machining) efficiency greatly, the wrinkle that contracts is evenly attractive in appearance.
Another object of the present invention provides a kind of wrinkle self-conductance device that contracts that is used to implement the above-mentioned wrinkle sewing structure that contracts, the convenient use.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of wrinkle sewing structure that contracts; Comprise the presser feet that is fixed on the head of sewing machine, be located on the Sewing machines panel and with the corresponding feed dog of presser feet be fixed in the eedle on the shank of head; The front of said eedle is provided with the wrinkle that contracts is pressed on the compressing tablet on the feed dog with cloth; The front end of said presser feet is pressed in lining above the compressing tablet, and the rear end of said presser feet is pressed in the lining that is sewed together and the wrinkle that contracts on the feed dog with cloth; Wherein, said presser feet and feed dog opposite joint built in together lining with the wrinkle that contracts with the chucking power of cloth less than said compressing tablet and feed dog the chucking power of wrinkling to contracting with cloth.
Before and after being used for, feed dog transfers cloth, and different to the vary in size gait of march that can cause cloth of the thrust (chucking power) of cloth.In the said structure; The wrinkle that contracts is pressed on the feed dog through compressing tablet with cloth; Therefore the handover speed basically identical of its pace and feed dog, and lining is only pullled down with cloth through the lining that is sewed together and the wrinkle that contracts and advanced, its speed are lower than the pace with cloth of wrinkling that contracts; The wrinkle that contracts like this can form nature with cloth and pile up wrinkle below lining, after eedle is made, just form the fringe margin that contracts.
Be used to implement a kind of wrinkle self-conductance device that contracts of the above-mentioned wrinkle sewing structure that contracts, comprise compressing tablet, said compressing tablet is fixed on the bit pressing shaft; Bit pressing shaft is rotated and to be arranged on the bearing and parallel with the Sewing machines panel; Circumferentially be fixed with rotation seat on the bit pressing shaft, rotation seat is connected with bearing through elastic mechanism, wherein; Said bearing can be installed on the Sewing machines panel, and said elastic mechanism is given with rotation seat through rotation seat and equally circumferentially is fixed on the trend that the compressing tablet on the bit pressing shaft rotates.Compressing tablet in the above-mentioned wrinkle sewing structure that contracts need keep a suitable thrust, thereby the effect of saving up strength realizes this function to the elastic mechanism in the above-mentioned wrinkle self-conductance device that contracts to rotation seat elasticity when compressing tablet compresses feed dog, and simple and practical, the convenient making.
As preferably; Above-mentioned elastic mechanism comprises the double-screw bolt that is fixed on the bearing, and the rotation end sky of said rotation seat is enclosed within on the double-screw bolt, and cover also is provided with the spring B and the nut that has been threaded on the said double-screw bolt; Spring B one end and rotation seat offset, and the spring B other end and nut offset.Because; When compressing tablet compresses feed dog; Thereby being discontiguous elastic mechanisms, rotation seat and bearing be able to act on, so, just can adjust the pressure that compressing tablet compresses feed dog through the elastic force of rotation nut adjustment spring; Wrinkle is adjusted the wrinkle that contracts promptly changes the wrinkle degree that contracts with the pace of cloth purpose with the suffered chucking power of cloth thereby reach even the time spent contracts.
As preferably; Above-mentioned bit pressing shaft can move axially, and said rotation seat is axially fixed on the bearing, and said rotation seat comprises that two skies are enclosed within the collar on the bit pressing shaft; Be arranged with spring A on the bit pressing shaft between these two collars and be fixed with the adjustment cover; Spring A one end and a collar offset, and the spring A other end overlaps with adjustment and offsets, and the adjustment cover offsets with another collar and both circumferentially fix through several location structures.Circumferentially fixing when adjustment cover and the rotation seat location structure through diverse location like this can be so that the state that compressing tablet is in work (can compress feed dog) or discharges, thereby does not need repetition dismounting, convenient use.
Several above-mentioned location structures comprise the alignment pin that is fixed on the said collar and are arranged on said adjustment and put several locating holes or the locating slot that matches with alignment pin.
As preferably, above-mentioned bearing is installed on the Sewing machines panel through mount pad, and bearing and mount pad are at one end hinged, and fix through the fastener snapping at the other end.Mount pad is fixed on the Sewing machines panel through screw, and such structure can conveniently be installed the wrinkle self-conductance device that contracts on the Sewing machines panel, reduce to take up room.
The present invention is owing to adopted above technical scheme; Through control the lining and the chucking power of wrinkle with cloth that contract are made it to exist gait of march poor between the two; Thereby make the wrinkle that contracts below lining, form the nature wrinkle that contracts, the formation fringe margin that contracts uniformly after making with cloth.Owing to do not need artificial wrinkle in the whole process, the wrinkle that contracts with make disposable in the lump completion, improved working (machining) efficiency greatly, and the product that the processes wrinkle that contracts is evenly attractive in appearance, stay in grade.The present technique scheme can be used for the herringbone sewing threads, and also can be used for the flatcar sewing.
