Detailed description of the invention
As described in Figure 1: a kind of for the adjustable presser feet in flat seam machine, it is characterized in that the slide rail carrier block 1 that comprises that an outline is rectangular shape, have opening dovetail groove slide rail 2 straight down at the lower surface of slide rail carrier block 1, the two ends of dovetail groove slide rail 2 connect two sides of slide rail carrier block 1, be embedded with the swallow-tail form slide block 3 suitable with dovetail groove slide rail 2 shapes at dovetail groove slide rail 2, be connected with the threaded rod 4 that direction is consistent with swallow-tail form slide block 3 glide directions in one end of swallow-tail form slide block 3, the end of described threaded rod 4 is connected with adjusting nut 6 through baffle plate 5 is rear, described baffle plate 5 is fixedly connected with slide rail carrier block 1, described slide rail carrier block 1 upper surface is fixedly connected with presser bar Connection Block 7, and described swallow-tail form slide block 3 bottoms are connected with presser feet by connecting plate 8, also has strip shape that direction is consistent with the swallow-tail form slide block 3 glide directions groove 9 of threading a needle on presser feet.
On threaded rod 4, also cover is installed with spring 10, and one end of described spring 10 contacts with baffle plate 5, and the other end contacts with swallow-tail form slide block 3.Threaded rod 4 is perpendicular with baffle plate 5, and the top of baffle plate 5 is fixedly connected with slide rail carrier block 1 by level board 11.Adjusting nut 6 is the cylindrical-shaped structure with screwed hole of centre, and is provided with scale on the sidewall of adjusting nut 6.Connecting plate 8 is connected with presser feet column 12, is provided with vertical location-plate 13 at the right edge place of presser feet.
First whole device is arranged on by presser bar Connection Block 7 on the presser bar of flat seam machine, the shape of the presser bar in the different flat seam machine that the shape of presser feet Connection Block 7 can connect as required as shown in the figure and supporting making, and be fixed with screw.After fixing device, make, in the time that needs are changed stitching specification, first the presser bar of flat seam machine is lifted, with finger twisting adjusting nut 6, because slide rail carrier block 1, baffle plate 5, the relative position of adjusting nut 6 can not change, so only have threaded rod 4 to carry out side-to-side movement in twisting adjusting nut 6, drive swallow-tail form slide block 3 in the interior motion of dovetail groove slide rail 2 simultaneously, and the presser feet being connected with swallow-tail form slide block 3 also carries out side-to-side movement, under continuous drive, strip shape on the final presser feet groove 9 of threading a needle does evolution with respect to Sewing needles also left and right, on adjusting nut 6, be provided with scale, rotate the scale that different angles can be corresponding different, the diverse location of groove 9 with respect to Sewing needles and the corresponding strip shape of different scales is threaded a needle, can regulate different scales according to different stitching technological requirements like this, make operation more accurately with directly perceived.
On threaded rod 4, be provided with spring 10 and be for spring 10 in rotation adjusting nut 6 also can be to 3 one driving forces of swallow-tail form slide block, make to regulate feasible more flexibly, the location-plate 13 that is located at presser feet one side is that the material for needs are made positions, one side of the cloth that needs can be made is close to location-plate 13 and then makes along location-plate 13, has played the effect that convenience is made and located.
The beneficial effect that adopts technique scheme to produce is: this adjustable presser feet can require to regulate for different stitchings the position of presser feet, adjusting by adjusting nut can convert the position that strip shape is threaded a needle between groove and Sewing needles, make the stitching of different process requirement, when noting be used in conversion process requirement, also to ceaselessly change presser feet, save the time, improved the efficiency of work.
