Description
Technical field
The utility model relates to sewing machine technique, particularly relates to a kind of rotary needle linkage of Sewing machines.
Background technology
One or more sewing thread used by Sewing machines, and sewing is formed one or more stitchings, makes the machine that one or more layers sewing interweaves or unites by a seam.Sewing function makes the goods such as the fabrics such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, the stitching neat appearance of stitching out, smooth firmly, sewing velocity is fast, easy to use.The sorting technique of Sewing machines is a lot, and commonplace is distinguish by stitching and purposes; The stitching of Sewing machines can be summarized as lock-type chain stitch and chain-type stitch two class, from the cross section of stitching, two sutures as two phase-locked lock, be thus called lock-type chain stitch; This stitching is used in the sewings such as the little cotton of shrinkage factor, wool fabric or leather, obverse and reverse shape is identical, as same dotted line, the feature of this stitching is stitching high resilience, can with sewing the flexible and suture that can not break, be applicable to the clothes of line elastic fabric or the easily loose goods of overseam and clothing base etc.In addition, Sewing machines can be divided into family expenses, industrial, service trade's machine according to purposes, can also be divided into hand sewing machine, foot-operated Sewing machines, electric sewer by drive form.
Existing common herringbone style car reequips to come on the basis of flat seam machine, and style style is fewer, and changing style needs to change floral disc, and style replacing construction is longer, and adopt that single tooth feeding style, pin code are shorter, stitching also unsightly.Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the utility model is reequiped on the basis of integrative feeding sewing machine, provides the rotary needle linkage of the Sewing machines that a kind of pin code is comparatively large, feeding is even, stitching is attractive in appearance, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A rotary needle linkage for Sewing machines, comprises balancing point frame, shank, cylinder, and described shank is arranged in the needle bar hole of balancing point frame, shank is provided with a guide finger, installs a guide pad above balancing point frame; A tooth bar is installed in balancing point frame middle part, tooth bar one end is connected on swing arm, sway bar center installs a rotating dog, the other end of swing arm is connected on cylinder connector, cylinder connector is fixedly mounted on the piston rod of a cylinder, cylinder is fixedly mounted on cylinder fixed block, and the rotating dog of sway bar center is fixedly mounted on cylinder fixed block, and cylinder fixed block is screwed on balancing point frame.
Described balancing point frame outer surface is with a gathering sill, and shank top arranges gear.
The piston rod of described cylinder seesaws, and drives cylinder connector to seesaw, thus drives swing arm to swing centered by rotating dog, and band carry-over bar seesaws, and drives shank to rotate.
The beneficial effect of the rotary needle linkage of Sewing machines described in the utility model is: reequip on the benchmark of synchronous Sewing machines, by setting up balancing point frame, shank, cylinder, has the advantages that pin code is comparatively large, feeding is even, stitching is attractive in appearance; Pattern control can coordinate with PLC automatic control system, and touch-screen selects style, changes style type at any time.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the rotary needle linkage decomposing schematic representation of Sewing machines described in the utility model embodiment;
Fig. 2 is the shank scheme of installation of the rotary needle linkage of Sewing machines described in the utility model embodiment.
In figure:
38, balancing point frame; 39, pin; 40, swing arm; 41, tooth bar; 42, cylinder fixed block; 43, guide finger; 44, shank; 45, guide pad; 46, cylinder; 47, screw; 48, rotating dog.
Detailed description of the invention
As shown in Figure 1-2, the rotary needle linkage of the Sewing machines described in the utility model embodiment, comprise balancing point frame 38, shank 44, cylinder 46, described shank 44 is arranged in the needle bar hole of balancing point frame 38, shank 44 is provided with a guide finger 43, one guide pad 45 is installed above balancing point frame 38, balancing point frame 38 outer surface is with a gathering sill, guide finger 43 wherein moves so that lead to shank 44 in the gathering sill of balancing point frame 38, after shank 44 upwards runs to certain altitude, guide finger 43 departs from the gathering sill of balancing point frame 38, shank 44 is just rotatable, after shank 44 moves downward certain distance, guide finger 43 enters in the gathering sill of balancing point frame 38, shank 44 just can not left-right rotation,
Correspondingly, shank 44 top arranges gear, a tooth bar 41 is installed in balancing point frame 38 middle part, tooth bar 41 seesaws and drives shank 44 to rotate, tooth bar 41 one end is connected on a swing arm 40 by a pin 39, a rotating dog 48 is installed at swing arm 40 center, swing arm 40 does oscillating motion centered by rotating dog 48, the other end of swing arm 40 is arranged on a cylinder connector by a pin, cylinder connector is fixedly mounted on the piston rod of a cylinder 46, cylinder 46 is fixedly mounted on cylinder fixed block 42, the rotating dog 48 at swing arm 40 center is fixedly mounted on cylinder fixed block 42, cylinder fixed block 42 is fixed on balancing point frame 38 by screw 47,
Correspondingly, the piston rod of cylinder 46 seesaws, and drives cylinder connector to seesaw, thus drive swing arm 40 to swing centered by rotating dog 48, thus band carry-over bar 41 seesaws, because the gear parts of tooth bar 41 with shank upper part engages, thus shank 44 is driven to rotate;
Correspondingly, the front and back action of cylinder 46 can be controlled by PLC system, and PLC system, according to the upper-lower position of inductor induction shank, passes through rotational cylinder shank in due course, the style program that coupling system is pre-designed, thus make the style that machine stitching goes out to design.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
