Computer embroidery machine thread cutting short troubleshooting and maintenance methods

There are two main problems with the short thread trimming of computer embroidery machines: short trimming thread and short trimming thread. The first thing to note is that the selection of needles for computerized embroidery machines is a key factor for embroidery. If the wrong needle is selected, it will cause thread breakage or needle breakage, which will greatly affect the efficiency of the embroidery factory. loss.

The following are only targeted troubleshooting ideas:

A. The length of the trimming thread and the short trimming thread are closely related to the tension of the thread take-up spring and the adjustment of the thread path. The tightness of the thread path and the tension of the thread take-up spring will shorten the thread trimming thread. Adjust in the following ways:

(1) Check the wire path, do not overtighten the wire spring and knob;

(2) Adjust the height of the thread yoke. The higher the pitch, the longer the upper thread. This idea is often effective in actual maintenance.

(3) Adjust the parameters, the cutting angle, and the larger the closing angle, the longer the face line.

B. Short trimming thread

(1) Check the depth of the closing knife. The shallower the closing knife depth, the shorter the bottom line;

(2) Check if the thread yoke is fastened too tightly. The proper tension of the bottom thread is: After the thread yoke is fastened, the bottom thread can be pulled by hand;

(3) Adjust the parameters, the cutting angle, and the larger the closing angle, the longer the face line.

Computer embroidery machine cutting line problem:

First of all, you should try some conventional troubleshooting schemes, such as checking whether there is a problem with the scissors, whether there is a problem with the position of the scissors, whether there is a problem with the buckle, or whether there is a problem with the hook knife. In addition, you can also try to tighten the cloth embroidery thread tightly and re-align the hook.

(1) Check the depth of the closing knife. The closing knife is too shallow to cut the thread.

(2) Change the parameters of the computer embroidery machine and check whether the angle of the dividing line is within 310-315;

In addition, there are some special reasons that can cause disconnection, even at room temperature. Sometimes when the weather is too hot, the needle is locked during the thread trimming operation, and the needle cannot be moved downward. The solenoid valve that locks the needle operates twice in succession, making it impossible to cut the upper thread. In short, the main reasons for continuous cutting are mechanical and electrical control. The mechanical side is mainly because the tension of the scissors is not tight. If the electrical capacity of the sewing control is not enough, the fastening is not tight, which will cause the continuous cutting.
