The extending direction of the limiting block 204 is parallel to the extending direction of the first limiting groove 201, and when the first connecting piece 6 drives the presser foot block 5 to move along the first limiting groove 201, one side of the presser foot block 5 abuts against one side of the limiting block 204, and the limiting block 204 plays a role in limiting and guiding the movement of the presser foot block 5.
So set up, presser foot piece 5 can not produce the skew at the in-process that removes, ensures that the center in presser foot space that presser foot piece 5 formed can not change to do not need readjusting the sewing central point, saved operating time, improved work efficiency.
Referring to fig. 1 to 6, the presser foot mounting plate 2 is provided with a notch 205, and the notches 205 of two presser foot mounting plates 2 in two sets of presser foot assemblies form a rectangular structure. The notch 205 is located at a side of the two presser foot mounting plates 2 of the two sets of presser foot assemblies, which is close to each other, so that the presser foot block 5 and the presser foot space formed by the presser foot block 5 can be easily observed through the notch 205.
Referring to fig. 1 to 6, the presser foot mounting plate 2 is provided with a recess 206 at the two sides of the notch 205. Through setting up the depressed part 206, the thickness of this part of presser foot mounting panel 2 is less than the thickness of other parts, and two depressed parts 206 of two presser foot mounting panels 2 form the depressed space, in sewing process, can pay attention to the pleasing to the eye degree of stitch through above-mentioned depressed space to and be convenient for observe the position of sewing origin when sewing, avoid influencing the sewing sight.
In the specific use process, the presser foot space can be further compressed for thinner cloth with larger elasticity, so that the thinner cloth with larger elasticity can be pressed more tightly during sewing, the elastic deformation quantity is reduced, and the failure rate can be greatly reduced.
According to the adjustable presser foot mechanism, the presser foot blocks 5 are driven to move through the first adjusting rods 4 and the second adjusting rods 3, the size of the presser foot space formed by the presser foot blocks 5 can be easily changed, so that the sewing requirements of different cloth materials on the market are met, the position of the presser foot blocks 5 can be quickly adjusted to change the presser foot space on the premise that disassembly is not carried out, the operation is simple, and parts cannot be lost. Because the first adjusting rod 4 and the second adjusting rod 3 synchronously drive the presser foot block 5 to move, the center of the presser foot space is not changed although the size of the presser foot space is changed, so that the sewing center point does not need to be readjusted, the operation time is saved, and the working efficiency is improved. Because the structure is less modified, the machine can be applied to any hitching machine, and the market acceptance is higher.
In addition to the adjustable presser foot mechanism disclosed in the various embodiments described above, the present utility model also provides a bar tacking machine comprising the adjustable presser foot mechanism described above. The same technical effect can be produced because the bar tacking machine comprises all the features of the adjustable presser foot mechanism.
It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present utility model and its core ideas.
