The shoemaking industry has a wide demand, which has also led to the shortage of shoemaking Sewing Machines, and the number of shoemaking manufacturers has sprung up like mushrooms. Therefore, the number of manufacturers purchasing shoe-making models has increased accordingly. There are many kinds of common auto Sewing Machine shoes, such as double thread side sewing machine. It can be said that there are many brands in the market, and the quality is also uneven. Therefore, when using this kind of equipment, people will find that there are often broken threads, broken needles, etc. What is the situation?
We know that people will rest when they are tired, and the machine is the same. Reasonable use can effectively prolong the service life. Problems such as thread breakage, skipped stitches, loose stitches, and broken stitches basically occur when the thread is not properly debugged in the early stage of use.
For example, the thread breakage problem is basically caused by the threading clip adjustment of the double-thread side sewing machine equipment being too tight and incorrect threading.
Needle breakage, and the broken needle problem is because the pulling speed of the product is too fast, which leads to the pulling of the machine needle and the breakage of the machine needle.
The flower needle phenomenon is that when the Shoes Sewing Machine sews the upper of the cloth fabric, we will find that two upper threads and the bottom thread are intertwined together from the reverse side. Sometimes there is only one stitch, and sometimes several stitches are connected together. Using a sewing machine The jargon for this phenomenon is called flower needles. The causes of flower needles are as follows:
(1) The positioning of the straight needle is too low, so that the loops of the needle are too large, and the loops are intertwined with each other.
(2) The small tongue of the needle plate is too small, and the stitches of the straight needles are easy to close together to produce the needle phenomenon.
(3) The bottom of the looper is too thin and round, so it is easy to separate the loops of the straight needle on the looper, so that the loops are intertwined with each other to produce flowery needles.
These three phenomena will cause flower needles to appear on the surface of the shoemaking sewing machine, so how do we solve them?
(1) Silicone oil can be added to the short needle thread, but silicone oil cannot be added to the long needle thread, because after adding silicone oil to the short needle thread, the thread will be smoother when the short needle thread passes through the looper without pause, so it is not easy to compare with the long needle thread. Needle and thread intersect.
(2) Take out the long needle thread from the small thread gripper on the needle bar, which can reduce the loop of the long needle and further reduce the chance of two straight needle threads intersecting.
(3) Tilt the two straight needles into a figure-eight shape without causing skipped stitches, and face the small mouth of the figure-eight shape to the operator, that is, make the distance between the coils thrown by the straight needles larger. Thereby solving the problem of flower needles.
Notes before use: The general double-thread side sewing machine has been tested before leaving the factory and is in the hands of the user, but most users have not read the manual in detail during use, which has caused this situation to happen frequently.
