Abstract

The utility model relates to a sewing upper thread clamping mechanism on sewing equipment. The sewing upper thread clamping mechanism comprises a machine head, wherein an upper thread clamping mechanism is fixed above a needle at the position of the front part of the machine head through a support. After full-automatic thread trimming is used by the sewing equipment, a sewing thread is clamped by the upper thread clamping mechanism through an upper thread clamping piece and a lower thread clamping piece, so that the problem that an upper thread is not long enough or the sewing thread can be loosened is thoroughly solved, and next sewing can be performed conveniently and easily.

Description

Sewing facial suture clamping mechanism on a kind of sewing device

Technical field

The utility model relates to sewing machine technique, specifically the sewing facial suture clamping mechanism on a kind of sewing device.

Background technology

On sewing device, use at present complete after the function of trimming, upper thread the end of a thread occurs that sewing thread the end of a thread falls short of sometimes, order does not hook bottom line next time while sewing, or sewing thread can depart from eedle and can not normally sew, the end of a thread of same bottom line also there will be and falls short of, or made the line heart drag turning by the inertia of shuttle race making the end of a thread partially short, while sewing, do not hook bottom line next time, the drawback that while starting to sew, seam is not reached the standard grade.

Utility model content

For above-mentioned deficiency, the utility model provides the facial suture clamping mechanism of the sewing on a kind of sewing device, when a sewing device uses entirely after trimming, facial suture clamping mechanism is clamped sewing thread by upper and lower thread tension disc. and thoroughly solve that upper thread falls short of or sewing thread can off-line phenomenon, conveniently can easily sew next time.

For achieving the above object by the following technical solutions:

Sewing facial suture clamping mechanism on a kind of sewing device, comprise head, it is characterized in that: above the eedle of the forward position of described head, be fixed with facial suture clamping mechanism by support, described facial suture clamping mechanism comprises thread tension disc, movable hook and lower thread tension disc, rear portion is made up of electromagnetic valve or pneumatic cylinder air valve, the centre of described movable hook in upper thread tension disc and lower thread tension disc, upper thread tension disc and lower thread tension disc are fixed on head by support, described movable hook is also connected with electromagnetic valve or pneumatic cylinder, movable hook and support or thread tension disc are provided with pilot hole, movable hook coordinates with pilot hole by screw.

Movable hook of the present utility model reaches forward sewing thread outward flange by the promotion of electromagnetic valve or pneumatic cylinder, then movable hook is promoted backward by the promotion of electromagnetic valve or pneumatic cylinder again, in the middle of pusher, movable hook taken back sewing thread, and by upper and lower thread tension disc, sewing thread is clamped. thoroughly solve that upper thread falls short of or sewing thread can off-line phenomenon, conveniently can easily sew next time.

Detailed description of the invention

As Figure 1-3, sewing facial suture clamping mechanism on a kind of sewing device, comprise head 1, above the eedle of the forward position of described head 1, be fixed with facial suture clamping mechanism 2 by support 3, described facial suture clamping mechanism 2 comprises thread tension disc 21, movable hook 22 and lower thread tension disc 23, and facial suture clamping mechanism 2 rear portions are made up of electromagnetic valve or pneumatic cylinder 4; The centre of described movable hook 22 in upper thread tension disc 21 and lower thread tension disc 23, upper thread tension disc 21 and lower thread tension disc 23 are fixed on head 1 by support 3, described movable hook 22 is connected with electromagnetic valve or pneumatic cylinder 4, movable hook 22 is provided with pilot hole 24 with support 3 or thread tension disc 21,23, movable hook 22 coordinates with pilot hole 24 by screw 25, between movable hook and support 3 or thread tension disc 21,23, is also provided with spring 26.

The utility model has been installed facial suture clamping mechanism at the annex of head eedle, when a sewing device uses entirely after trimming, the anterior movable hook of facial suture clamping mechanism reaches forward sewing thread outward flange by rear portion by the promotion of electromagnetic valve or pneumatic cylinder, then movable hook is promoted backward by the promotion of electromagnetic valve or pneumatic cylinder again, in the middle of pusher, movable hook taken back sewing thread, and by upper and lower thread tension disc, sewing thread is clamped, thereby thoroughly solve, upper thread falls short of or sewing thread meeting off-line phenomenon, conveniently can easily sew next time.

Claims
