How To Handle The Left Hand Sewing Thread When The Double Needle Sewing Machine Is Empty?

The double needle sewing machine is commonly known as the "double needle machine". For the left side of the double needle sewing machine. Needle breakage The analysis of faults may be caused by the change of sewing thread twist during sewing operation, which is a broken line fault often encountered by two needle machines. Due to the unique relationship between the needle and the spindle of the double needle machine, the line above the theory requires that the left needle should be twisted with the right twist, the right needle should be left twisted, or the left and right needles should be left twisted together.

The actual use is usually using the same twist to the face line, the market supply of the face line is mostly left twist, perhaps the left needle after using the left twister, the left needle thread twisting leads to the broken line after splitting. We try to circle the line around the needle, or reverse the line, maybe there will be unexpected gains. We can also do some work in terms of machine adjustment, such as re adjusting the position of Zola hook to ensure surface line from Spinning shuttle Smooth surface. In addition, we will reduce the lateral clearance between the left shuttle and the left needle, take the needle of the shuttle tip as the standard, and raise the lifting cam so that the tooth can be tilted forward to reduce the take-up resistance.

There is another solution: we can immerse the line in water for more than half an hour and let it dry for a few minutes before using it again. As the line is soaked in water, the viscosity will be released. The supply line of the rotary shuttle is also uniform. It can sew two different sizes of sequins at the same time, facilitate the use of high-speed sewing machine, improve the utilization ratio of the equipment, adopt servo motor control, have the function of automatically stopping the needle, fix the length of sewing, adjust the sewing speed freely, and save about 50% of electricity compared with the ordinary sewing machine. The advanced fork lift mechanism can meet the needs of some users just sewing straight lace, saving investment cost and improving production efficiency. The outlet is stable. The large amount of water contained in the line also plays a lubrication role in the movement, reducing the friction and heating of the line in high-speed motion, thus reducing the probability of breaking.

In addition, we can also take Double needle sewing machine The pressure of the presser foot is reduced a little; the silicone oil is added to the suture; the polishing teeth of the cloth delivery tip can be programmed to set up the supporting fork feeding mechanism; the stepping angle of rotation, the step length of the chip can be programmed, and the blunting measures are taken in the condition of the nail machine.
