Problems solved by technology

[0002] In order to improve sewing efficiency, automatic thread cutting devices are usually used in sewing equipment, which not only makes sewing smooth, but also reduces thread ends in clothes and improves the efficiency of subsequent finishing. figure 1 As shown, the knife body 1 is provided with a cutting knife edge 2 and an inclined thread clamping head 3. The thread clamping head 3 tightens the thread and then rotates the movable knife. The cutting knife edge cooperates with the fixed knife to cut off the bottom thread and the upper thread in the suture, The thread clamping head 3 in the rotary moving knife of the existing lockstitch sewing machine is an inclined straight line, forming a sharp corner 4. When the suture moves on the thread clamping head, the thread tends to slip out of the 4 sharp corners, so that thread cutting cannot be realized, which affects It improves the stability of automatic thread cutting, increases the thread ends on the clothes after sewing, and reduces the efficiency of subsequent finishing

Embodiment 1

[0013] See figure 2 and Figure 4 , a rotary movable knife structure for a lockstitch sewing machine, which includes a rotary movable knife body 1, the rotary movable knife body 1 is arc-shaped, a cutting edge 2 is arranged on the rotary movable knife body 1, and the rotary movable knife body 1 Corresponding to the front of the cutting edge 2, there is a buckle thread head 3. The rotating movable knife body 1 and the thread tie head 3 are integrally formed. The height of the protrusion is 0.3mm-0.8mm, and one side of the buckle head 3 is an inclined edge 5, forming a pointed shape, and the buckle groove 4 is arranged on the inclined edge 5.

Embodiment 2

[0015] See image 3 and Figure 4 , a rotary movable knife structure for a lockstitch sewing machine, which includes a rotary movable knife body 1, the rotary movable knife body 1 is arc-shaped, a cutting edge 2 is arranged on the rotary movable knife body 1, and the rotary movable knife body 1 Corresponding to the front of the cutting edge 2, there is a buckle thread head 3. The rotating movable knife body 1 and the thread tie head 3 are integrally formed. The height of the formed protrusion is 0.3mm-0.8mm, and one side of the buckle head 3 is an inclined edge 5, forming a pointed shape, and the buckle groove 4 is arranged on the slope 5. A plurality of wire fastening grooves can be set.

[0016] In the embodiment, "front" is just for the convenience of description, and it is a limitation on the relative position of the cutting edge and the thread thread head. Different reference objects can also be used in different descriptions, and it cannot be understood mechanically. ...

Abstract

The invention provides a rotary moving blade structure for a flat sewing machine. The rotary moving blade structure comprises a rotary moving blade body with a cutter edge, and the rotary moving bladebody is correspondingly provided with a thread fastening head in front of the cutter edge. The rotary moving blade structure is characterized in that the thread fastening head is provided with a thread fastening groove. The rotary moving blade structure has advantages that thread ends on sewed clothes are reduced, and subsequent finishing efficiency is improved.
