With the continuous development of industrial technology, the product structure of sewing equipment is also developing in the direction of high-speed and serialization. At the same time, computer technology is also widely used in sewing machines, and a large number of automated and intelligent industrial sewing machine spare parts have come out one after another.
How to thread industrial sewing machine spare parts?
Why is the upper thread of industrial sewing machine spare parts always wound on the bobbin?
What is the working principle of industrial sewing machine spare parts?
1. When using industrial sewing machine spare part, make sure that the needle is in the upper needle position; the presser foot is lowered.
2. Push down the threading control lever with the fingers of the left hand; pull the thread through the wire hook (A) with the right hand and then pull it to the right. Note: The finger must be vertically downward to press the threading lever, not to the right.
3. When the threading lever is pressed to the lower part of the industrial sewing machine spare part, the threader will automatically rotate and the threading hook will pass through the needle hole.
4. Pull the thread toward the needle, and gently lift it up against the needle, so that the thread is hooked by the threading hook (B).
5. Gently pull the thread end and release the threading lever at the same time, the thread hook will rotate to hook the thread into the needle hole to form a thread loop.
6. Pull out the thread end of the needle hole about 10 cm from the back.
1. When the above problems occur, it is recommended to check the threading method. In this case, the upper thread take-up lever is not hung up. Just rethread the thread.
2. If it is confirmed that the threading method is correct and the industrial sewing machine spare parts still has such a problem, you can take the bottom shuttle out to see if there is a burr on the edge.
The mechanism of industrial sewing machine spare part in which the needle belt guide thread pierces the sewing material is called the needle bar mechanism. The task of the needle bar mechanism is to drive the needle, guide the upper thread through the sewing material, and form the upper thread loop to prepare for the interweaving of the suture.
The function of the needle bar mechanism is ultimately realized by the machine needle. The industrial sewing machine spare part sews the sewing materials together during work, and the machine needle has to puncture. The movement mode of needle piercing sewing material has vertical direction, horizontal direction, linear type and curved type. Sewing machines have different types of needle bar mechanisms due to their different uses. Most industrial sewing machine spare parts perform vertical reciprocating linear motion. Some special machines, such as buttonhole machines, button sewing machines, embroidery machines, etc. not only require Vertical reciprocating linear motion and lateral swing at the same time, but this lateral swing time must start after the needle leaves the sewing material and end before entering the sewing material.
The widespread use of industrial sewing machine spare parts has continuously increased the demand for them in the market. STRONG H MACHINERY TECHNOLOGY CO.,LTD, as a Chinese pioneer in rolling and bending machines, can ensure the tube rolling machines’ quality and after-sales service.
