Causes of broken needle faults and troubleshooting methods:
Under normal circumstances, the needle breakage of the round head buttonhole machine is caused by machine misalignment and misalignment of parts. Therefore, the main reasons for this failure are: the needle is not loaded up to the top, and the needle touches the needle. The position of the plate and the crochet needle is too close to the needle, the matching action of the branching fork (switching needle) is incorrect, the needle thickness is incorrectly selected, the needle guard is loose, the spring of the branching fork (switching needle) is too small or the spring is off , And the interlocking installation is not equal.
For the above reasons, we can separately install the needle up to the top and tighten the fastening screw; adjust the needle plate position correctly: adjust the gap between the needle and the crochet needle; adjust the position of the branch fork according to the standard, and the timing of the action; choose Appropriate needle; position the needle guard correctly; replace the spring with too small elastic force, if the branch line is yellow and fall off, reinstall the spring; adjust the position of the interlock device according to the standard to remove the fault .
Causes of noise failure and troubleshooting methods:
According to the analysis, the reasons for the high noise of the round head buttonhole machine are: lack of oil in the machine, loose or worn parts of the machine, and changes in the position of the machine parts. In this regard, we suggest to take the following measures: fill the key friction parts of the machine with professional lubricants, re-tighten and re-tighten the loose parts in accordance with the standards, and replace the parts with new ones for severely worn parts. The changes of parts shall be readjusted according to the stated standards until they are suitable.
