The principle of sewing thread tension of sewing equipment is mainly formed by obtaining tension through a certain threading path and device. Using this tension principle, designers of sewing equipment can find a reasonable threading form, and operators can find a method of adjusting tension.
There are three main aspects of the principle of thread tension in sewing equipment:
1. The suture can maintain the required shape only under a reasonable tension;
2. The stitches are tensioned on the sewing equipment through curved surfaces and tensioners;
3. The ideal thread tension of the sewing equipment is to meet the technical requirements. The smaller the peak value of the thread tension, the better, and the smaller the tension fluctuation, the better.
The places where the principle of tension is used on sewing equipment are mainly: adjustment of the amount of thread when the stitch length changes; formation of stitches; adjustment of the shape of the coil, etc.
The maintenance of sewing equipment usually contains two meanings, one is the meaning of preventive maintenance and the other is the meaning of production maintenance. The combination of the two is equipment maintenance.

The so-called preventive maintenance refers to regular inspection or regular care before the machine is damaged.
The so-called production maintenance refers to how to reduce production costs and improve product quality maintenance.
The "three-level maintenance system" for sewing equipment is an effective way to rely on everyone, give full play to the enthusiasm of employees, implement scientific management, and improve equipment maintenance.
Daily maintenance
The daily maintenance of sewing equipment is carried out by the operating staff. For ordinary equipment, the equipment is carefully inspected before and after the shift for 5 to 10 minutes, and for key equipment, the equipment is carefully inspected before and after the shift for 10 to 15 minutes. It is required to wipe all parts of the machine and fill it with lubricating oil, so that the equipment is always kept neat, tidy, lubricated and safe. Failure of equipment in the shift should be eliminated in time.
2. Primary maintenance
The machine needs to perform first-level maintenance once a month (one shift). The first-level maintenance is carried out by the operator and guided by the mechanics. The equipment is partially dismantled, inspected and cleaned in accordance with the requirements, clearing the oil passages and pipelines, cleaning the oil lines, linoleum, and oil filters, and adjusting the positioning and coordination gaps of all parts of the equipment. Tighten the loose screws.
3. Secondary maintenance
In addition to the first-level maintenance content, the second-level maintenance is carried out by the mechanical repair and maintenance company. It is carried out every other year to perform partial disassembly inspection and repair of the equipment, replace or repair worn parts, clean, change oil, and inspect and repair electrical parts. Local recovery accuracy meets the requirements of normal machine operation.
