Utility model content

A purpose of the present utility model is to provide a kind of sewing machine plain cloth device, and it has can will treat cloth presser at sewing Flat advantage.

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

A kind of sewing machine plain cloth device, including base plate, the presser foot component on base plate, described presser foot component includes being driven Arm, the presser feet being connected with transmission arm, described presser feet is provided with for the first piston pushing meanss by lower foot clamp, described transmission arm It is connected by hinge assembly with base plate, at described presser foot component, is additionally provided with pressuring flat device, described pressuring flat device is included positioned at transmission Second piston pushing meanss on arm, be connected with the piston rod of second piston pushing meanss be bulldozed group for be bulldozed cloth Part.

It is arranged such, when cloth is placed on base plate, cloth is spacing by presser feet first, and presser feet is promoted by first piston Device pushes, and transmission arm and base plate move to base plate direction around hinge assembly, after presser feet is depressed on cloth, then are pushed away by second piston The piston rod of dynamic device is released being bulldozed assembly to the direction deviating from transmission arm.Have common knowledge understand, cloth enter cloth direction It is to be advanced at sewing machine from away from sewing machine, cloth first passes through at presser feet, then pile up storage at push arm.Therefore in seam During threading, cloth advances at presser feet from away from presser feet, is bulldozed assembly by the cloth on base plate from presser feet spacing place It is bulldozed, make sewing position keep smooth, be easy to follow-up sewing work.

Arrange further：Described it is bulldozed the curved boom that assembly includes being fixedly connected with piston rod, deviates from piston rod positioned at curved boom The pressing plate of one end.

It is arranged such, the power on piston rod is transferred on pressing plate curved boom, pressing plate is used for contacting at base plate, works as piston rod When pushing away before promoting curved boom, curved boom band dynamic pressure plate, it is capable of smoothing the effect of cloth.

Arrange further：Described transmission arm includes bending segment, horizontal segment, and described horizontal segment is provided with fixing axle, described work Stopper rod sliding coaxial with fixing axle is connected.

It is arranged such, due to horizontal segment, motion amplitude is little in the course of the work, so the relative fortune of piston rod and fixing axle Dynamic position motion amplitude is little, and inclined degree is little, so the resistance that piston rod is subject in slipping is little.Sliding connects can be real Now drive the reciprocating effect of curved boom.

Arrange further：Described fixing axle is connected by detachable member with horizontal segment, described detachable member include with Horizontal segment deviates from what the first anchor ear branch tablet that bending segment one end is fixedly connected and the first anchor ear branch tablet were connected by securing member Second anchor ear branch tablet.

It is arranged such, by being detachably connected of the first anchor ear branch tablet and the second anchor ear branch tablet, can be by fixing axle Disassemble from horizontal segment.It is conveniently replaceable commonly used pressuring flat device.

Arrange further：Described fixing axle is connected by detachable member with horizontal segment, and described detachable member is set to The securing member deviate from bending segment one end clip being fixedly connected with horizontal segment, being used for fastening clamp.

It is arranged such, clip is capable of the purpose disassembling fixing axle from horizontal segment, and clip is whole for one The sheet of body, so compared to the anchor ear having two panels branch tablet, be difficult to lose part.

Arrange further：The hinged seat that described hinge assembly is included on base plate realizes phase with hinged seat and transmission arm To the bearing pin rotating connection.

It is arranged such, hinged seat plays fixing effect, bearing pin and realizes transmission arm by spacing for transmission arm to hinged seat It is connected with relatively rotating of hinged seat.

Arrange further：Described base plate include two pieces of bar beams, be located at two pieces of bar beams between walk needle tray.

It is arranged such, bar beam can be played a supporting role to cloth, walk needle tray for accommodating sewing needle, when under sewing needle When stabbing to cloth, it stabs out one section of cloth i.e. walking in needle tray.The setting walking needle tray prevents sewing needle to withstand on to make on floor Become to damage.

Arrange further：Described presser foot component, it is bulldozed assembly and is symmetrical arranged for symmetrical centre with walking needle tray.

It is arranged such, presser foot component can apply to cloth to the power of cloth applying in two panels bar beam with being bulldozed assembly Aequilateral uniform power so that during lower pin, sewing needle fall within cloth will not because of other everywhere stress irregular and occur Situation about shifting during cloth sewing.

Arrange further：Presser foot component described in two is deviated from base plate one end and is fixedly connected by force block, described force block with The piston rod of first piston pushing meanss is fixedly connected.

It is arranged such, the power of first piston pushing meanss can be transferred on two presser foot components by force block, makes two Presser foot component can stress be pressed on cloth simultaneously, and preventing from being separately controlled can generation time error during two presser feets.

Of the present utility model another object is that provides a kind of sewing machine, and it has the seam that can reduce generation in sewing work The advantage of position pleating quality problem of threading.

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

A kind of sewing machine, with sewing machine plain cloth device described above.

In sum, the utility model has the advantages that：On the basis of spacing cloth, cloth can be played Smooth effect, this effect that smooths is implemented by two groups of assemblies, promotes by Mechanical Driven mode, accuracy is high, beneficial to clothes life Produce industry and manufacture the smooth reliable clothing of structure.
