The so-called computer-controlled sewing machine is popularly speaking, it is the computer sewing machine. With the continuous adjustment of the market and consumption structure, the low- and medium-speed industrial sewing machine can no longer meet the production needs, and the sewing machine is developing in the direction of high-speed and serialization. Electronics, computer technology It is widely used on sewing machines. The computer-controlled sewing machine can not only realize intelligent control, greatly improve production efficiency and reduce operation difficulty, but also can have machinery to complete part of the operator's work, which is convenient for enterprise digital management.

    1. Features of computer sewing machine

    1. Low noise and low vibration design.

    The computerized sewing machine uses computer anatomy, from the structure of the casing to the small parts of each part, the optimal design is realized. As a result, it can minimize noise and vibration in daily work. In addition, the computerized sewing machine achieves the best balance in the design of the machine head. The transmission of the upper shaft and the lower shaft is driven by a synchronous toothed belt, which greatly reduces the noise and realizes low vibration and low noise work.

    2. High degree of automation and labor-saving operation.

    The computerized sewing machine can automatically complete the set sewing work. Such as automatic seam sewing, automatic adjustment of sewing thread tension of thick and thin sewing material, automatic speed change, automatic torque change, automatic thread trimming, automatic needle compensation and so on.

    3. The computer sewing machine has high stability.

    Due to the electronic or computer control system, after the computerized sewing machine reaches the maximum speed, the sewing stability is better, especially the seamability, including good stitches, softness, and stability.

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

    One computer sewing machine can complete the work that several mechanical sewing machines can do. For example, in industrial zigzag sewing machines, a mechanical zigzag sewing machine can only sew one pattern, while a computer zigzag sewing machine can sew 20 or more patterns. In addition, because the computer-controlled sewing machine increases the adjustment range of the feed dog, it can sew more different types of fabrics. And adjust the most suitable differential amount according to various fabrics. When feeding back and forth, even if the stitch length is changed, the differential ratio will not change, so there is no need to adjust.

    5. Clean and environmentally friendly performance

    Usually in the development process of mechatronics sewing machines, designers have emphasized the cleanness of the machine and non-contaminated sewing. Through the design of the sewing machine head, the needle bar, thread take-up lever and rotary hook are not used around the needle to achieve cleanliness Sewing.

    2. How to choose a high-quality computer-controlled sewing machine?

    Choosing a high-quality computer sewing machine is usually selected from four aspects: listening, watching, checking and testing.

    1. Listen

    When idling and with a load, listen to the sound of the motor and the parts inside the machine when it is running. The sound should be uniform, stable, and soft, and there should be no irregular noise and abnormal noise.

    2. Look

    When the needle bar moves up and down at slow, medium and high speeds, the movement of each part should be even and flexible.

    3. Check

    The fit of each part of the machine should be tightly touched and pressed by the relative moving parts, and there should be no looseness or movement jamming. All links can operate smoothly.

    4. Try

    Put on the thread when trying it out, try to sew the stitches of different patterns with fabrics of different thicknesses. The stitches should be neat and uniform, without jumpers and stitches. The adjustment should be flexible, uniform and convenient.
