We all know that straw hats will wear out quickly when in use, and some small faults will appear from time to time, which will affect the working efficiency of the bottom thread machine. In response to this situation, the editor of Jingneng Sewing Machine would like to tell everyone the effective way to reduce the bottom thread machine. As a method to reduce the failure of the bottom thread machine, careful maintenance and use is a relatively simple and effective method, so today we mainly discuss how to reduce the failure rate of the bottom thread machine through careful maintenance and use.
1. In order to ensure that the cam driving roller and the thread trimming cam of the big bottom thread machine do not collide during operation, it is necessary to ensure that there is sufficient clearance between the two. We can perform this operation on the lower shaft by moving the cam of the bottom thread machine left and right, and fix it with screws after fixing the gap.
2. Before using the bottom thread machine, please pay attention to the correction of the cutting point of the machine head to avoid improper operation.
3. Place the cam drive roller of the bottom thread machine at the end of the swing groove to reduce the possibility of poor drive.
4. When using the large bottom thread machine, the groove surface of the thread trimming cam must be in contact with and fixed to the thread trimming cam to reduce the situation that the bottom thread machine does not cut the thread.
