If the overall strength is insufficient, it may be that the pressure of compressed air is not enough, and the compressed air is at least 4MPa, which is the minimum requirement. If the atmospheric pressure is maintained at about 7MPa, the strength is enough.

If one side of the hexagon is not strong enough, it may be that the cylinder on that side is not enough. You can adjust the intake valve of the cylinder, that is, the small rotating switch, to turn up the intake and return air.

If the above elimination is not enough, there may be two reasons. First, the cylinder leaks, and you can tell if there is a hiss by listening to the sound. Repairing means replacing the cylinder. Another reason is that there is a problem with the electrical signal conversion switch of the control cabinet, which is more complicated. You can consult the manufacturer to replace the switch or repair it.

I hope the answer to the problem of insufficient strength of 6-sided plastic automatic rice packaging machine will help you.
