The demand for sewing machine knife is increasing year by year because of the continuous market expansion of the clothing industry. Only by increasing production efficiency can enterprise costs be increased. Therefore, more and more manufacturers are focusing on the high-end sewing machine knife.
What should we do if the sewing machine knife does not move?
How to maintain sewing machine knife?
What is the development history of sewing machine knife?
1. Check the blade depth of the sewing machine. The shallower the knife depth, the shorter the bottom line.
2. Check whether the buckle fork is fastened too tightly. The proper tension of the bottom thread is: After the buckle fork is buckled, the bottom thread can be pulled by hand.
3. Pay attention to check whether the position of the tangent cam is correct, there is a great possibility of problems in this place.
4. Check whether the handwheel is installed correctly and whether the sensor at the handwheel is installed correctly.
5. If it is an industrial sewing machine, pay attention to whether the sewing machine knife is installed at the front end, that is, the thread is cut too early.
6. If it is a heavy-duty machine or a machine that imitates a heavy-duty machine, pay attention to whether the installation position of the fixed knife is on the far left.
7. Pay attention to whether the pressure of the thread stopper is too large.
8. Pay attention to whether the thread reel and thread guide are perpendicular to each other. If the angle between the thread reel and thread guide is too large, the thread resistance will be too large and the thread head will be too short when cutting the thread.
9. Some of these machines are prone to not resetting the thread trimming sewing machine knifes. If the moving knife is stuck, the needle will collide with the moving knife when the needle is raised for the second time, which will damage the needle and the left side of the moving knife. When there are scars on the left side of the movable knife, the upper thread will not smoothly enter the gap of the movable knife during thread trimming, resulting in the upper thread being too short. When the needle is lifted for the second time, the end of the thread will fall off the eye of the needle.
1. The oil holes on the head of the sewing machine knife lubricate the upper shaft and the parts connected to the upper shaft.
2. The internal parts of the panel and the movable parts connected to each part. Lubricate the presser foot bar, the needle bar and the parts connected to it.
3. Wipe the movable parts of the lower part of the sewing machine knife and add less oil. The refueling amount of each refueling hole and refueling part does not need to be too much, just one or two drops will do.
By the mid-1980s, with the continuous adjustment of the market and consumption structure, the product structure of sewing equipment was developing in the direction of high-speed and serialization based on the medium and low-speed sewing machine knife. Electronic and computer technologies were also widely used in sewing machines. application. At the same time, sewing machine knife also completed the establishment of a spare parts supporting system and built a huge sewing machine sales network.
To meet these growing demands, STRONG H MACHINERY TECHNOLOGY CO.,LTD. has various sewing machine knifes and they are all more effective, reliable, and consistent.
