Analysis of the working principle of industrial double-needle sewing machine

2024-02-18

Industrial double-needle sewing machine is a kind of professional equipment widely used in garment manufacturing and textile industry. Its efficient working principle is the key to ensuring production efficiency and product quality on the production line. Let`s take a closer look at how industrial twin-needle sewing machines work.

1. Double needle working method:

Industrial double-needle sewing machines sew with two needles working simultaneously. The two needles are usually arranged in parallel and can be adjusted as needed to meet different sewing requirements. This double-needle working method can complete the sewing of two lines at the same time, improving sewing efficiency.

2. Alternating movements of the upper and lower needles:

When working, the upper and lower needles of the industrial double-needle sewing machine will move alternately. First, the upper needle is passed through the fabric from above to form a needle hole, and then the lower needle is passed through the needle hole from below, alternating with the upper needle. In this way, the two needles complete a sewing process at the same time, forming a stitch.

3. Cooperation of needle and thread:

In terms of the cooperation between needle and thread, industrial double-needle sewing machines usually use two independent bobbins and thread clips. Each needle is connected to an independent spool, and the tension of the thread is adjusted through the tension device on the spool to ensure that the tension of the two threads is balanced, thereby ensuring uniform and stable sewing results.

4. Sewing lines and guides:

In order to ensure the precision and accuracy of double-needle sewing, industrial double-needle sewing machines are usually equipped with precision sewing lines and guides. These devices ensure that the two needles move along a predetermined path during sewing, thereby ensuring sewing accuracy and consistency.

5. Lubrication and cooling system:

In order to ensure the stable operation and long-term use of the machine, industrial double-needle sewing machines are usually equipped with lubrication and cooling systems. These systems can provide timely lubrication and cooling to the moving parts of the machine, reduce friction and wear, and extend the service life of the machine.

6. Automated control:

With the advancement of technology, modern industrial double-needle sewing machines are usually equipped with automated control systems that can realize automated sewing operations. These systems can automatically adjust the needle movement speed, thread tension, etc. according to preset parameters and modes, thereby improving production efficiency and product quality.

To sum up, industrial double-needle sewing machines achieve efficient and stable sewing through multiple working principles such as double-needle working mode, alternating movement of upper and lower needles, coordination of needles and threads, precise line guidance, lubrication and cooling systems, and automated control. Operation has become an indispensable and important equipment in the clothing manufacturing and textile industry.
