The paper machine gimbal pin break caused by the paper feed nozzle valve

When the paper feed nozzle is burnt, it will also cause the universal joint shaft pin to break. After replacing the broken shaft pin, do not rush to start the work, you should find out the cause of the break. When disassembling the universal coupling of the Paper Machine, the marking of the universal joint should be made to prevent the angle from changing during the reinstallation, so that the relative position of the paper feed to the other parts of the paper machine changes. , causing out of sync.

1. Main engine and paper machine universal coupling shaft pin break

If the universal joint pin between the main unit and the paper machine is broken, check the loader of the paper feeder. During the inspection, the paper feeder wheel can be driven to check the load of the paper feeder. If the paper loader is large, you must find the reason for the paper feeder. During the inspection, if the paper feeder and the Feida universal coupling are disengaged, the handwheel is turned and the load is normal, indicating that the load comes from the paper feed, and the paper feed can be judged to be burnt.

2. Paper machine and paper feeder Feida transmission universal coupling shaft pin break

If the universal joint shaft pin between the paper feeder and the paper feed is broken, it is mostly caused by the burning of the paper feed nozzle. In order to reduce the failure rate of the paper feed in the work, we should pay attention to the maintenance and cleaning of the paper feed, regularly add lubricant to the paper feed parts, and regularly clean the paper feed nozzle valve to keep the gas. The valve is clean.
