How to choose a computer sewing machine? These four points teach you how to choose a sewing machine.

The so-called computer-controlled sewing machine is a computer sewing machine. With the constant adjustment of the market and consumption structure, the medium and low speed industrial sewing machines can no longer meet the production needs, and the sewing machine is developing in the direction of high speed and serialization. Electronics, computer technology Widely used on sewing machines. The computer-controlled sewing machine not only can realize intelligent control, greatly improve production efficiency, reduce operation difficulty, and can mechanically complete part of the operator's operation, which is convenient for digital management of enterprises.

First, the characteristics of computer sewing machine

1. Low noise and low vibration design.

The computer sewing machine uses computer anatomy, which optimizes the design from the structure of the casing to the small parts of each part, thereby minimizing noise and vibration during daily work. In addition, the computer sewing machine achieves the best balance in the design of the machine head. The transmission of the upper and lower shafts is transmitted through the synchronous toothed belt, so that the noise is greatly reduced, and the low vibration and low noise work are realized.

2. High degree of automation and low effort.

The computer sewing machine can automatically complete the set sewing work. Such as automatic seaming, automatic adjustment of thick seam sewing thread tension, automatic shifting, automatic torque change, automatic thread trimming, automatic needle filling and so on.

3. The stability of the computer sewing machine is high.

Due to the use of electronic or computer control systems, the sewing machine has good stability after reaching the maximum speed, especially the seamability, including good stitching, softness and stability.

4. The performance of the single sewing machine for computer sewing machine is expanded.

A computerized sewing machine can perform a number of mechanical sewing machines. For example, industrial zigzag sewing machines, generally a mechanical zigzag sewing machine can only complete a pattern of sewing, while a computer zigzag sewing machine can complete 20 or even more patterns of sewing. In addition, since the computer-controlled sewing machine increases the adjustment range of the feed dog, it can sew more different types of fabric. According to the various fabrics, the most suitable differential amount is adjusted. When the feed is sent back and forth, even if the stitch length is changed, the differential ratio does not change, and it is not necessary to adjust.

5, clean and environmental performance

Usually in the development process of mechatronic sewing machine, the designer emphasizes the clean and non-staining sewing of the machine. Through the design of the sewing machine head, the needle bar, the thread take-up rod and the hook are not used to clean the oil. Sewing.

Second, how to choose a quality computer-controlled sewing machine?

The selection of high-quality computer sewing machines is usually selected from four aspects: listening, watching, checking and testing.

1. Listen

When listening to the motor and the internal parts of the machine, the sound should be uniform, stable and soft when idling and carrying the load, and there should be no irregular noise and abnormal sound.

2, look

The needle bar is moved up and down at slow speed, medium speed and high speed respectively, and the moving parts should be even and flexible.

3, check

The cooperation of the various parts of the machine should be done by touching and pressing the parts with relative motion. There should be no looseness or movement jamming. All aspects can be operated smoothly.

4, try

When putting it on the line during trials, try to stitch the stitches of different patterns with different thickness of fabric. It should be neat and uniform, without jumper and jump stitch. The adjustment should be flexible, uniform and convenient.
