1、 First, find out the reason and check the cylinder management problem of the pneumatic device of the punch feeder. When the air pressure is not enough or the air pipe is not enough, resulting in low pressure, it is not enough to completely rely on the pressure spring when clamping the material. If the material is too thick, it is easy to clamp, which will not only make the material slip, but also connect an air pipe on the solenoid valve to the cylinder, so that the cylinder will have thrust to clamp the roller on the press feeder more tightly, so as not to slip. It can also be realized by increasing the air inlet pressure and increasing the cylinder pressure.
2、 Check whether the power spring of the feeding leveling roller is qualified and whether the rebound force can meet the requirements. If not, replace it with a new one. Increase the pressure,
3、 When the feeding speed of the press feeder can be met, the distance between the press feeder and the leveling machine or material rack shall be shortened as far as possible to reduce the waiting area, so that the material weight in the waiting area will be reduced, so as to reduce the load of the press feeder and prevent the servo press feeder from slipping due to the excessive material in the waiting area
