How to solve the problem of inaccurate feeding of feeder

Compared with traditional manual feeding, the biggest advantage of the feeder is that it has higher feeding accuracy and better stability, so the finished products produced are of higher quality, which can make the stamping customers' products more competitive in the market. Feeding accuracy is one of the core performances of the feeder. Once the feeding is inaccurate, it will greatly affect the product quality and cause the finished product to be too high. Therefore, the phenomenon of inaccurate feeding must be solved in time.

There are many types of feeders, the most commonly used ones are the Zhanmeng roller feeder and the NC servo feeder. Their structures and principles are very different, so the reasons for inaccurate feeding of the feeder are also very different. Stamping customers need to find the root cause according to different machine models, and then solve it in a targeted manner.

1. Reasons and solutions for inaccurate feeding of roller feeder:

1）The pressing force of the pressure spring is not enough, and the material slips during the conveying process, resulting in inaccurate feeding. Solution: Increase the pressing force of the pressure spring to prevent the material from slipping

2.）Inaccurate feeding caused by incorrect material thickness adjustment or failure to adjust according to the actual material. Solution: Adjust the material thickness adjustment plate of the roller feeder according to the actual material thickness.

3） Inaccurate feeding caused by failure of the brake device of the feeder or insufficient sensitivity. Solution: Re-grind the brake device or replace the new brake pads. This requires professional technicians from Zhanmeng to handle.

4） There are foreign objects such as iron filings in the gears of the roller feeder, causing inaccurate feeding. Solution: Clean and maintain the roller feeder regularly, remove foreign objects in the gears and lubricate the gears with clean engine oil.

5.）Wear of the roller copper sheet in the one-way device causes inaccurate feeding. Solution: Contact Zhanmeng technicians for repair and replacement.

2. Reasons and solutions for inaccurate feeding of servo roller feeder:

1）The pressing force of the pressure spring is not enough (the pressure spring is located in front of the machine, under the support wheel), and the material slips during the conveying process, resulting in inaccurate feeding. Solution: Increase the pressing force of the pressure spring to prevent the material from slipping.

2）There are foreign objects such as iron filings in the gears of the NC feeder, causing inaccurate feeding. Solution: Clean and maintain the Zhanmeng NC feeder regularly, remove foreign objects in the gears and lubricate the gears with clean engine oil.

3）The gap between the synchronous pulleys of the servo motor is too large, causing inaccurate feeding. Solution: Remove the cover and adjust the gap between the synchronous pulleys.

4）The release time (angle) of the feeder is not adjusted correctly, causing inaccurate feeding. Solution: After stopping, re-adjust the release angle of the NC feeder according to the stamping process.
