Clothing Enterprises To Purchase Sewing Machine Performance Testing Knowledge

With domestic sewing machines Manufacturer A number of mechanical and electrical sewing machine models have been launched. Now, more and more brands of mechanical and electrical sewing machines are available in the domestic market. This contrasts with the situation that the famous foreign brands dominate the domestic electromechanical integration sewing machine market in the past few years. As a result, clothing companies should pay more attention when choosing products like this.

Price and performance are all primary considerations. Because the mechanical and electrical sewing machine is much more expensive than the traditional mechanical sewing machine, so when some low price domestic mechanical and electrical integration products appear, the users should not be confused by the price gap before buying, because in the current reality, there are good and bad phenomena in the performance of domestic products. brand Compared with the quality and performance of some domestic machines, there are still some deficiencies. Users should consider comprehensively when purchasing such machines.

First of all, when purchasing this kind of machine, users must go to the regular place (the manufacturer's direct store, or the distributor's shop with legitimate agency qualification) to purchase, and ensure the regularity of the purchased sewing machine (with the certificate of qualification and related department's certification) and the necessary after-sales service promise. Then, the field test machine, the most important part, should be repeated and patiently debug the machine. In this process, users can examine the performance of electromechanical integrated sewing machines from the following five points.

First, the stability of sewing. Because of the adoption of electronic or computer control system, the mechanical and electrical integration sewing machine has better stability of sewing after reaching the highest speed, especially the sewing property, including whether the stitches are good, whether it is soft, stable, whether there are jumps, disconnection and wrinkles. Therefore, if the machine is found to have adverse reactions in this respect, do not buy it.

In addition, buy this kind. machine The sewing speed of machine should not be overemphasized. Although the mechanical and electrical sewing machine is much faster than the traditional sewing machine in sewing speed, in the process of garment production, the speed requirement is not as fast as possible, which takes into account the endurance of cloth and suture. Therefore, when choosing a mechanical and electrical sewing machine, we should weigh the sewing speed and the stability of the machine. Do not blindly follow the salesmen's recommendation and pursue the sewing speed of the machine. {page_break}

Second, clean and environmentally friendly. Usually, during the development of Mechatronics sewing machines, designers have emphasized the cleanliness of machines and no pollution sews. Through the design of sewing machine heads, clean sews can be achieved by needling oil rods around the needle bar, picking rod and shuttle. Therefore, when choosing a machine, the user must try the machine again and again to make sure that it will not bring oil to the cloth and sewing material when it is working.

Third, the performance of single machine is expanding. A mechanical and electrical sewing machine can complete some mechanical sewing machines. For example, industrial sewing machine, a mechanical zigzag sewing machine can only finish one pattern stitching, while a computer bending machine can finish 20 or even more patterns stitching. In addition, because the computer controlled sewing machine increases the adjusting range of the cloth feeding teeth, it can sew more different kinds of cloth. And according to the various fabrics to adjust the most appropriate differential, before and after the cloth delivery, even if the needle distance is changed, the differential ratio will not change.

Fourth, low noise and low vibration. Design 。 Mechatronics sewing machine has applied computer anatomy. From the structure of the shell to the small parts of each part, the optimum design has been realized, so that it can suppress noise and vibration to the maximum extent in daily work. In addition, this kind of machine has achieved the best balance in the design of the machine head, and the transmission of the upper shaft and the lower shaft is driven by the synchronous toothed belt, resulting in a significant reduction in noise and low vibration and low noise. Therefore, when the user buys, no matter which brand of machine, no matter the price difference, the low vibration and low noise processing of Mechatronics sewing machine is one of its characteristics. If this effect is not good, it should give up the purchase.

Fifth, high automation and low cost. When testing the machine, the user must debug the automation function of the mechanical and electrical sewing machine to see if it can finish the sewing work automatically. For example, laser or infrared film positioning, automatic sewing, thick seam sewing seam tension automatic adjustment, automatic transmission, automatic torque changing, automatic thread cutting, automatic filling needle, man-machine dialogue user programming, sewing process automatic tracking and so on.

In addition, some humanized design of Mechatronics sewing machine is also one of its characteristics. If this kind of machine is wider than the traditional sewing machine, the fabric to be sewed is easier to pick and place and rotate; the bottom winding device is installed on the upper arm of the machine, the adjustment of the coil volume and the disassembly and assembly of the shuttle core are simple; only the lifting button or the rotary pedal can be used to perform the work, or even the full automatic operation; the easy to understand operation disk enables the operator to memorize easily, and the operation does not cause confusion.
