Correct adjustment of sofa sewing machine foot press to improve work efficiency

The sofa sewing machine is a special sewing equipment for sofas in industrial production. It is also a kind of thick-material sewing machine. It uses a comprehensive feeding method and a super long cylindrical sewing table. Powerful and stable feeding force, easy to sew multi-layer thick and heavy materials, accurate and beautiful stitches, and can be used for zigzag pattern sewing.

The foot-pressing height of a sofa sewing machine needs to be higher in order for thick or multi-layered materials to pass smoothly, so the flexibility of the foot-pressing is important. We can adjust the foot pressure as follows when it needs to be adjusted or when it is not moving flexibly.

First, loosen the mask screw on the sewing machine with a zigzag screwdriver. Then remove the unscrewed screw and remove the sewing machine face cover by hand. Find the press rod responsible for running the foot on the sewing machine and continue to loosen the parts under the press rod with a screwdriver. When all parts under the lever are loose, the adjusting foot can be twisted directly by hand. But be careful not to bend the foot of the foot press when adjusting, the needle on the foot press must be aimed at the hole position below.

When the adjustment is complete, tighten all parts with a screwdriver, cover them and restore them. This will allow the foot to drop properly. the pressure of the sewing machine foot can be distinguished by the adjusting screw of the head. when the cloth layer is thicker, the downward pressure will be higher. When the cloth layer is thin, the upward pressure is small. The pressure adjustment function of the foot press is to select the pressure according to the nature of the seam material.

If a small presser foot cannot move flexibly, it will affect the passage of the cloth and the seam of the sofa sewing machine. Similarly, inappropriate foot pressure selection can not smoothly complete the sewing, and the failure of a small part will affect the overall work, so we can not ignore the daily maintenance and maintenance of the sewing machine.
