1. Dust plug and check valve:
If the dust-proof plug surface in the feed impeller box is blocked by cement, the compressed air cannot enter the impeller box to aid flow, and the output will be unsmooth and unstable..If the dust plug or the one-way valve falls off and is damaged, the cement dust enters the compressed air pipeline of the packaging machine, which will block the entire pneumatic system components and damage it..
Therefore, when it is found that the cement flow is small, there is no foreign matter blockage at the nozzle, the compressed air pressure and the throttle valve are normal, check and replace the dust plug in the impeller box to ensure unobstructed air flow.If dust is found in the compressed air pipeline and the solenoid valve is blocked, the dust plug is damaged and needs to be replaced.
2. Throttle valve:
The throttle valve plays the role of adjusting the flow-assisted air volume. If it is found that the air flow cannot be adjusted or is blocked, it needs to be replaced to ensure that the flow-assisted air volume can be adjusted at any time according to the needs..
3. Pneumatic control valve:
The spring and piston in the valve are easily blocked and damaged, resulting in the failure of the pneumatic flow aid to connect, and the cement in the impeller box cannot be in a fluid state, and the nozzle discharge is small or does not discharge..
When it is found that the output is small and the nozzle is not blocked by foreign matter, the quick connector on the detachable air pipe can check whether the compressed air pressure and flow are normal. If the air flow is small, the pneumatic control valve should be removed to clean the spool, or replaced directly.
4. Solenoid valve:
Affected by the moisture in the compressed air, the valve core will rust and jam after a period of use of the solenoid valve, unable to operate normally or not in place, resulting in slow or no movement of the cylinder.
When Y1 and Y2 fail, the three-position cylinder cannot operate normally or is slow, and the coarse and fine flow valves cannot be opened or closed in time, which will cause a large error in the weight of the cement bag..
When Y3 fails, it may happen that the bag pressing head cannot be pressed or loosened in time.Cause the packaging bag to fall off at the beginning of filling.Or it can’t be broken and torn when pushing the bag.
When Y4 fails, the packaging machine may not be able to push the bag, or the speed of pushing the bag is too slow, the cement bag cannot fall into the middle of the belt of the machine, or even directly fall to the machine, it is easy to block the bag and squeeze the bag..
Therefore, after the packaging machine is shut down, the solenoid valve needs to be checked, and the solenoid valve that is not working properly is removed to clean the spool, or directly replaced.If there is no daily downtime, the solenoid valve should be inspected and cleaned at least once a week to ensure that the packaging machine is in good working condition.
