Problems solved by technology

In the existing sewing machine, in order to make the suture have an appropriate tension, a spring structure is arranged on the path of the suture, and the spring is used to keep the shape of the suture elastically pressed. When the suture is pulled, the deformation of the spring increases , At this time, the tension is too large, it is easy to shrink and wrinkle the fabric, resulting in unsightly stitches, and more seriously, thread breakage will occur. When the thread is broken, the thread will fall out of the thread hole. Difficult and inefficient to reload the wire into the spring

Embodiment Construction

[0011] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0012] Such as figure 1 As shown, a suture tension control device includes a machine head 1, a column 2 fixed on the machine head 1, and a thread passer 3 sleeved on the column 2, and the thread passer 3 passes through a belt 4 is connected with a belt pulley 5, and the belt pulley 5 is connected with a motor 6, which reduces the frictional force, that is, reduces the tension of the suture, and the stitches made are neat and beautiful, flat and firm, and the generation of broken threads is avoided. The sewing speed is fast and the work efficiency is improved.

[0013] In order to prevent the thread passer 3 from slipping out of the column 2 ...

Abstract

The invention relates to a thread sewing tension control device which comprises a machine head, a stand column which is fixed on the machine head, and a thread-passing device which is sleeved on the stand column. The thread-passing device is connected with a belt pulley through a belt. The belt pulley is connected with a motor. A blocking piece is fixed at the top end of the stand column, and the motor is a synchronous motor. By changing sliding friction to rolling friction, friction force is reduced, thread sewing tension is reduced, sewed lines are neat, attractive, level and firm, broken ends are prevented from being produced, thread sewing speed is quick, working efficiency is improved, and the thread sewing tension control device has good economical benefit.

Description

technical field [0001] The invention relates to a tension control device, in particular to a suture tension control device. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The sewing machine can sew fabrics such as cotton, hemp, and silk And leather, plastic and other products. In the existing sewing machine, in order to make the suture have an appropriate tension, a spring structure is arranged on the path of the suture, and the spring is used to keep the shape of the suture elastically pressed. When the suture is pulled, the deformation of the spring increases , At this time, the tension is too large, it is easy to shrink and wrinkle the fabric, resulting in unsightly stitches, and more seriously, thread breakage will occur. When the thread is broken, the thread will fall out of the thread hole. Reloading th...
