Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a single-needle sewing machine with an automatic crossbeam and a cutter. Background Art

[0002] The traditional single-needle machine has its frame process line working on the cutting machine at the rear end. The traditional single-needle machine process is as follows: The first step is to loosen the cloth clamping mechanism on both sides, and the rollers in the cutting machine rotate the fabric to move the new fabric forward. The second step is that the rollers rotate to the specified distance and stop, then clamp and tighten the fabric, and then the single-needle machine starts to sew the pattern. The third step is that after sewing the pattern, loosen the cloth clamping mechanism on both sides, and the rollers and side cutters in the cutting machine start to rotate at the same time. After the pattern reaches the specified position, the transverse cutter in the cutting machine works to cut the fabric. Because the cloth clamping mechanism on both sides needs to be loosened, the fabric will have a certain elasticity, and the thickness of the fabric is unevenly distributed. When the fabric is sent to the cutting machine, the error between the side cutter and the frame will be relatively large.

[0003] Therefore, it is necessary to propose a new type of automatic crossbeam with a cutter single needle machine to solve the above problems, so as to solve the problem of inaccurate fabric cutting when the traditional single needle machine performs the fabric cutting process after sewing.
