Abstract
The invention relates to a press foot adjusting structure for an extremely thick material in a pattern sewing machine. The press foot adjusting structure comprises a middle press foot, and the middle press foot is fixed at one end of a press rod. The press foot adjusting structure further comprises a three-eye oscillating plate, the three-eye oscillating plate is respectively hinged to a driving connecting rod, the other end of the press rod and one end of a small connecting rod, the other end of the small connecting rod is hinged to one end of an oscillating bar and a supporting rod, the other end of the oscillating bar is connected with an adjusting rod, and the middle end between two ends of the oscillating bar is further hinged to a fixed seat. The press foot adjusting structure has the advantages that the height of the middle press foot can be adjusted at any time by the adjustment of the adjusting rod according to different thicknesses of sewn materials in the sewing process, the materials are pressed, and sewing quality is guaranteed.
Description
Technical field
The present invention relates to a kind of pattern sewing machine, the middle presser feet that relates in particular to this pattern sewing machine is adjusted structure.
Background technology
As seen from Figure 1: 10 is body, and middle presser feet 11 is fixed on one end of depression bar 12; Three oscillating decks 14 are hinged with one end of drive link 13, depression bar 12, small rod 15 respectively; One end of the other end of small rod 15 and fork 16 and pole 19 are hinged; The other end of fork 16 and holder 17 are hinged; 18 adjustment springs are one end and pole 19 hinged ends that load on fork 16.In this structure, the adjusting of middle presser feet 11 height, needs to adjust and is fixed on the position on depression bar 12 one end, therefore can only on the material of same dimensions thickness, make.Make if necessary on the material of different size gauge thickness and make, need middle presser feet separated with depression bar by being connected and fixed again after material thickness adjustment.Therefore in the process of making when object to be sewn material thickness is often changed, it is very inconvenient to regulate.
Summary of the invention
The technical issues that need to address of the present invention have been to provide the presser feet for super thick material in a kind of pattern sewing machine and have adjusted structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: middle presser feet; Described middle presser feet is fixed on one end of depression bar; Also comprise: three oscillating decks; Three described oscillating decks are hinged with the other end of drive link, depression bar and one end of small rod respectively; The other end of described small rod and one end of fork and pole are hinged; The other end and the adjusting lever of described fork join; Intermediate ends between described fork two ends is also hinged with holder.
Compared with prior art, the invention has the beneficial effects as follows: can make Cheng Qian, and according to the different-thickness of making material, by adjusting lever, adjust the adjustment of carrying out at any time middle presser feet height, material is compressed, and guarantee sewing quality.
Accompanying drawing explanation
Fig. 1 is presser foot schematic diagram in pattern sewing machine in prior art.
Fig. 2 is structural representation of the present invention.
Fig. 3 is adjusting lever change, middle presser feet height change schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As seen from Figure 2: in pattern sewing machine of the present invention, for the presser feet of super thick material, adjust structure and comprise: presser feet 21; Described middle presser feet 21 is fixed on one end of depression bar 22; Also comprise: three oscillating decks 24; Three described oscillating decks 24 are hinged with the other end of drive link 23, depression bar 22 and one end of small rod 25 respectively; The other end of described small rod 25 and one end of fork 26 and pole 29 are hinged; The other end of described fork 26 and adjusting lever 28 join; Intermediate ends between described fork 26 two ends is also hinged with holder 27.
In pattern sewing machine of the present invention, for the presser feet of super thick material, adjust structure and settle casing 20.
Operation principle of the present invention is: when adjusting lever 28 dextrorotation are stretched out downwards, fork 26 and adjusting lever 28 contact jaws are around holder 27 pin joints to lower swing, and fork 26 upwards rises with small rod 25 hinged ends, drives small rod 25 to move upward; And small rod 25 moves upward and drives three oscillating decks 24 and pole 29 to move upward, thereby make depression bar 22 and the middle presser feet 21 that is fixed on depression bar 22 moves up (as shown in Figure 3); Otherwise when adjusting lever 28 is retracted, middle presser feet 21 moves down, and reaches the adjusting of centering presser feet height.
