The electric control system is the key part of every canvas sewing machine. It is generally composed of a control subject, a control object, and a sensing part, and specifically includes a control box (controller, driver), a motor and an electromagnet, a sensor, and some auxiliary components. The cooperation and linkage of some mechanical parts of the thick-thread sewing machine have contributed to the automation of the sewing machine. Just like the "core" of a powerful computer, the "core" is like the heart of a person. It can make all parts work together and enhance the automation of machinery. The control part of the electronic control system mainly controls the driving operation of two components such as the motor and the electromagnet.
      Thread jumping is a phenomenon that the industrial canvas sewing machine cannot continuously form stitches because the hook at the bottom of the machine cannot hook the upper thread or the upper thread slips off after being hooked during the sewing process of the industrial canvas sewing machine. This is mainly caused by the inconsistency of the movement time or movement position of the needle and the hook. Of course, it is also possible that the needle cannot form a loop and cause the stitches to skip. If there is a jumper, you can find the reason from the following aspects:
     When we encounter skipped stitches on canvas sewing machines, we usually check the following points to determine the
