Description

Technical Field

[0001] The utility model relates to the technical field of knitting, in particular to a thread catching structure for a template sewing machine. Background Art

[0002] Template sewing machines combine garment template CAD software, garment template sewing CAD software, and advanced CNC technology to fully automate template production. This improves production efficiency and product quality, reduces the technical requirements of skilled workers, and replaces the original manually operated sewing machine with a more automated computer-controlled machine. The thread grabber is a critical component of template sewing machines. Existing thread grabbers have complex and inefficient structures, resulting in suboptimal thread grabbing. Utility Model Content

[0003] Therefore, in order to solve the above problems, the present invention proposes a thread grabbing structure for a template sewing machine which has good thread grabbing effect and is easy to use.

[0004] The thread grabbing mechanism comprises a thread grabbing mechanism provided on a head body of the template sewing machine, the thread grabbing mechanism comprising a mounting seat, a limiting plate, a driving mechanism, a rotating shaft and a thread grabbing hook, the mounting seat is provided on one side of the lower portion of the head body and the mounting seat is located on one side of the presser foot of the head body, the limiting plate is provided on the mounting seat, the lower portion of the head body is located at the presser foot side and extends downward to form a positioning portion, the rotating shaft is rotatable and passes through the positioning portion at the lower portion of the head body in a horizontal direction, the upper portion of the thread grabbing hook is connected to the rotating shaft, the driving mechanism is provided on the head body and the output end of the driving mechanism is connected to the end of the rotating shaft away from the connection with the thread grabbing hook, the driving mechanism drives the rotating shaft to rotate and thereby drives the thread grabbing hook to hook the yarn and drive the yarn to be buckled on the limiting plate to complete the yarn grabbing, or the driving mechanism drives the rotating shaft to rotate and thereby drives the thread grabbing hook to release the grabbed yarn.

[0005] As a further improvement, the wire grabbing hook is L-shaped, and the free end of the vertical portion of the wire grabbing hook is fixedly connected to the rotating shaft.

[0006] As a further improvement, a yarn hooking groove is provided on the transverse portion of the thread grabbing hook.

[0007] By adopting the above-mentioned technical solution, the beneficial effects of the present invention are as follows: by arranging a limit plate on one side of the presser foot, and arranging a thread grabbing robot composed of a driving mechanism, a rotating shaft and a thread grabbing hook at the lower part of the head body, the yarn is effectively grabbed to the limit plate located on one side of the lower part of the head body for fixation, thereby realizing the yarn end grabbing and adjustment, and the horizontally arranged rotating shaft enables the thread grabbing hook to realize large-angle rotation control to grab the yarn, and the thread grabbing is flexible, the thread grabbing effect is good, and it is easy to use. Through further arrangement, that is, the thread grabbing hook is provided with a yarn groove, the yarn grabbing is more stable and reliable, and can be widely promoted and applied. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of the three-dimensional structure of an embodiment of the utility model;

[0009] Figure 2 This is a schematic diagram of a partial structure from another angle of an embodiment of the utility model;
