AI Technical Summary

Technical Problem

When clamping yarns of existing template sewing machines, the clamping force is easily affected by knitting pulling, resulting in yarn clamping failure and affecting the sewing quality.

Method used

A wire clamping device including a mounting base, a guide rod, a tie rod, a spring, a driving mechanism and an adjustment cover is designed. By setting a limiting post and a wire opening under the spring, the yarn is avoided from being pulled, and clamping stability is improved through the spacing between the limiting post and the wire pressing plate, and a cylinder or a screw motor is used as a driving mechanism.

Benefits of technology

It effectively avoids the influence of the yarn clamping force, improves the sewing quality, and reduces the yarn friction through porcelain eye columns, ensuring that the yarn passes smoothly and clamping is more stable and reliable.

Description

Technical Field

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

[0002] A template sewing machine is a machine that combines garment template CAD software, garment template sewing CAD software, and advanced numerical control technology to fully automate the production of applied templates. 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. However, the automatic thread clamping device of existing template sewing machines has different yarn states at both ends of the clamped yarn during thread clamping. The yarn at one end at the yarn supply end is clamped and does not move, while the other end at the presser foot end is pulled up and down with the knitting action, thereby causing the yarn to be pulled, causing the yarn end clamped by the automatic thread clamping device to be constantly pulled. Over time, this will affect the clamping force of the thread clamping ring, causing the yarn clamping to malfunction, affecting sewing quality. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned problems, the present invention provides a thread clamp for a template sewing machine, which can avoid affecting the clamping force of the thread clamp for clamping the yarn and improve the sewing quality.

[0004] In order to solve this technical problem, the utility model adopts the following solution: a thread clamp for a template sewing machine, comprising a thread clamp arranged on the head body of the template sewing machine, the thread clamp comprising a mounting seat, a guide rod, a pull rod, a spring, a driving mechanism and an adjusting cover, the mounting seat is arranged on the head body, the guide rod is arranged on one side of the mounting seat, the adjusting cover is movably sleeved on the guide rod, the spring is sleeved on the guide rod and the spring is located between the adjusting cover and the mounting seat, the driving mechanism is arranged on the head body and the output end of the driving mechanism is connected to the adjusting cover via the pull rod to drive the adjusting cover toward the mounting seat to extend and retract the compression spring to clamp or release the yarn, the mounting seat is provided with a limit column below the spring, and the limit column is provided with a wire opening.

[0005] As a further improvement, the driving mechanism is a cylinder or a screw motor.

[0006] As a further improvement, the limiting column is a porcelain eye column and the porcelain eye on the porcelain eye column is a wire opening.

[0007] A further improvement further includes a wire pressing plate, which is sleeved on the guide rod and located between the mounting seat and the spring.

[0008] As a further improvement, the spacing between the limiting column and the wire pressing plate is 1-3 cm.

[0009] By adopting the above-mentioned technical scheme, the beneficial effect of the utility model is as follows: by arranging a limit column under the spring, the yarn at the other end away from the yarn supply end after being wound around the guide rod is wound around the wire opening of the limit column and then sent to the knitting needle of the head body, so that the yarn clamped by the thread clamp will not be pulled, which can avoid the clamping force of the yarn clamped by the thread clamp being affected and the sewing quality is improved. The limit column is set as a porcelain eye column so that the smooth ceramic surface can reduce the friction of the yarn and make it pass smoothly. By setting the wire pressure plate, the clamping of the yarn is more stable, and the limit column and the wire pressure plate are spaced apart to avoid the yarn being inserted into the wire pressure plate when moving up and down during weaving, so that the thread clamp clamps the yarn more stably and reliably, which can be widely promoted and applied. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a three-dimensional structural diagram of an embodiment of the present utility model. DETAILED DESCRIPTION
