Since mechatronic sewing machines are much more expensive than traditional mechanical sewing machines, when some domestically produced mechatronics products at very low prices appear, users should not be confused by the immediate price gap when purchasing, because they are based on the current reality. In other words, there is a phenomenon of uneven performance of such domestic products. Compared with well-known foreign brands, some domestic machines are still lacking in quality and performance. Users should consider comprehensively when purchasing such machines.
First of all, when purchasing this type of machine, users must go to a formal place to purchase, and ensure the regularity of the sewing machine purchased (have a certificate of conformity and a certification certificate from the relevant department) and obtain the necessary after-sales service commitments. Then, it is the field test machine. This link is the most important, and the machine should be debugged repeatedly and tirelessly. In this process, users can focus on testing the performance of the mechatronics sewing machine from the following five points.
First, the stability of sewing. Because modern sewing machines mostly use electronic or computer control systems, the mechatronics sewing machine has better sewing stability after reaching the maximum speed, especially the sewability, including whether the stitches are good, soft, stable, whether or not Excellent performance in skipped stitches, broken threads, and wrinkles. Therefore, if you find that the machine has adverse reactions in this regard, do not buy it.
In addition, when purchasing this type of machine, the sewing speed of the machine should not be overemphasized. Although the sewing speed of the mechatronic sewing machine is much faster than that of the traditional sewing machine, in the process of garment production, the speed requirements are not as fast as possible. Well, this needs to take into account the endurance of the fabric and stitches. Therefore, when choosing a mechatronics sewing machine, the sewing speed should be weighed against the stability of the machine. Do not blindly follow the recommendations of the salesperson and pursue the sewing speed of the machine.
Second, clean and environmentally friendly performance. Usually in the development process of mechatronics sewing machines, designers have emphasized the cleanness of the machine and non-staining sewing. Through the design of the sewing machine head, no oil is used around the needle bar, thread take-up lever and rotary hook to achieve cleanliness. Sewing. Therefore, when selecting a machine, the user must repeatedly test the machine to make sure that it will not bring oil stains to the fabric and sewing objects during work.
Third, the performance of stand-alone use has expanded. One mechatronics sewing machine can complete the work that several mechanical sewing machines can do. For example, the zigzag sewing function of the sewing machine. Generally, 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 electrically 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 according to various fabrics. When performing forward and backward feeding, Even if the stitch length is changed, the differential ratio will not change, and there is no need to adjust it.
Fourth, the design of low noise and low vibration. The mechatronics 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, this type of machine achieves the best balance in the design of the machine head. The upper and lower shafts are driven by synchronous toothed belts, which greatly reduces noise and realizes low vibration and low noise work. Therefore, when users buy, no matter which brand of machine, no matter how much the price difference is, the low vibration and low noise processing of the mechatronics sewing machine is one of its characteristics. If the effect is not good, you should abandon the purchase.
Fifth, the degree of automation is high and the operation is labor-saving. When testing the machine, the user must debug the automation function of the mechatronics sewing machine to see whether it can automatically complete the set sewing work, such as automatic seam, automatic adjustment of sewing thread tension of thick and thin sewing material, automatic speed change, automatic change Torque, automatic thread trimming, automatic needle compensation, man-machine dialogue, user programming, automatic tracking of sewing process, etc.
In addition, some of the humanized designs of mechatronics sewing machines are also one of its characteristics, so make corresponding comparisons when purchasing. For this type of machine, the unwinding part is wider than the traditional sewing machine, making the fabric to be sewn easier to take, place and rotate; the bobbin thread winding device is installed on the machine arm, and the adjustment of the winding amount and the disassembly and assembly of the bobbin are simple; Need to lift the button or operate the pedal to work, even fully automatic; the easy-to-understand and easy-to-use operation panel makes it easy for the operator to remember, and there is no confusion during operation.
