With the rapid economic development, we have entered the era of intelligent industrialization, and the embroidery industry has ushered in more opportunities and challenges for development. The competition in the computer embroidery industry is not limited to embroidery quality, but also includes a long-term machine efficiency. The fierce market competition in the computer embroidery market has allowed embroidery enterprises to continue embroidery innovation and improve machine efficiency.
Of course, there are many reasons for thread breakage. Poor quality of the embroidery thread can easily lead to thread breakage. The size of the machine shuttle bed gap can also cause thread breakage and needle breakage. The number of times of disconnection is too high. First, check if the plate is too short. If there is no problem with the tape, check the line to see how tight it is, and see if the line on the machine's line is smooth. If the line is smooth, check the line for quality problems, all of the above are normal, check the machine shuttle bed to see if the gap is too large or too small. In general, the computer embroidery machine is disconnected due to the following reasons:
1 Reason for adjusting the line
Reasons for adjusting the line, if the line is not adjusted properly, it may easily lead to disconnection, such as knotting at the end of the line, unsmooth lines, and cracks across the line.
2 reasons
The reason for the plate belt is that when the computer embroidery plate is made, the plate belt has too many short stitches, which may cause thread breakage. For example, where the strips cross or overlap, there are too thick stitches, which are prone to broken lines.
3 Quality reasons for embroidery threads
The reason for the quality of the embroidery thread is that the embroidery thread of unqualified quality has many knots in it, and it is easy to break the thread due to uneven tension.
4 Reasons for shuttle beds
The causes of shuttle beds are mainly divided into three categories. ① The shuttle bed has burrs (wear) and is easy to break. It can be polished with 1200 fine sandpaper and smooth, and the shuttle bed can only be replaced with new ones. ②. The distance between the embroidery machine's shuttle bed and the needle, if it is too large or too small, it will cause thread breakage, needle breakage and missing stitches, which will indirectly cause thread breakage. The normal clearance is generally about 0.3mm. ③. Take-up time of shuttle bed, take-up time is 201 ° (+ -1 °). If the deviation is too large, it is easy to disconnect.
5 Reasons for Matching Needle and Thread
The reason for the embroidery machine to match the thread, according to the different functions of computer embroidery machine, usually thin needle with thin thread, thick needle with thick thread.
6 Reasons for machine pin plate holes
The reason for the needle hole of the machine is to see if the needle hole of the embroidery machine has burrs and is not smooth. If it is not polished with sandpaper for a long time, it is easy to break the thread.

7 Needle itself
The needle itself, for example, the needle slot of the embroidery machine is not in the correct direction, the needle is misaligned, and the bottom dead point of the needle is gone. This will cause broken needles. When the bottom dead point of a needle is generally 201 °, it is advisable to see more than half of the pinholes at a squint angle of 45 °.
8 Causes of machine presser foot
The reason for the presser foot of the machine is that the presser foot of the embroidery machine is too high, and the thread will break when the machine is running. Generally, the height of the presser foot to the throat plate is about 0.8mm.
9 Machine cam cause
The reason for the cam of the machine, the thread take-up cam of the machine is tangled, and if it is not cleaned, the needle thread breaks easily.
10 Other reasons
There are cracks in the ceramic hole of the thread, the upper thread is not working, etc. You need to replace it with a new one.
