Reasons and solutions for inaccurate feeding of three-in-one feeder
Introduction to the structure of the three-in-one feeder: The three-in-one feeder is composed of an uncoiler, a feeder, a straightening machine, and three machines. The decoiler is equipped with a hydraulic trolley and a hydraulic expansion system for material loading, which effectively improves work efficiency. , achieving zero-risk material feeding and fully automatic operation, making the entire machine operation more humane. Of course, the three-in-one feeder is just like people. During long-term use, it will get sick, go on strike, and have unpredictable failures, such as inaccurate feeding. When encountering such a situation, we will usually be in a hurry and don't know how to deal with it. Today, the feeder manufacturer is here to tell you something that bothers everyone so much, that is, the reason why the feeder is not feeding accurately and how to solve it. The following is a detailed description:
1. Mold positioning problem. During the feeding process of the three-in-one feeder, in order to meet the accuracy requirements, it is generally required to set positioning pins in the mold. If the material will deviate during the closing process, it is most likely that the positioning pins of the mold are missing. Once done, the positioning pin needs to be remade.
2. The quality problems of the coil material itself will lead to inaccurate feeding problems. If a roll has serious burrs, is bent, uneven, or has a serpentine width, it will easily cause the material to deviate during the feeding process, so the roll needs to be replaced with a standard roll.
3. Incorrect adjustment of the blocking wheel of the three-in-one feeder will cause the material to deviate. The tightness setting of the pressing device of the three and one feeders is different. The material blocking device in the unwinding part is not adjusted to the appropriate degree. The width of the guide wheel in the leveling and feeding part is not adjusted to the appropriate degree. The discharge wheel is not adjusted to the appropriate degree. If the width is not adjusted to an appropriate degree, the pressing force of the pressing device will be uneven, which can easily cause the material to deviate. Therefore, the three-in-one feeder must be adjusted according to the instruction manual of the three-in-one feeder. The retaining wheel of the feeder.
4. There is a machine problem with the three-in-one feeder itself. For example, the rollers are not concentric, or the servo is abnormal, or the material rack design is unreasonable, which will lead to material deviation problems. When these problems occur in the machine, you need to contact the manufacturer, and the manufacturer will arrange professional masters to repair it.
5. There is foreign matter in the feeding machine. There are foreign objects in the gears or rollers, which will cause the material to shift during feeding or leveling. It is necessary to remove the foreign objects and clean the gears or rollers.
6. The roller pressure of the three-in-one feeder is insufficient or the roller is relaxed. During the use of the three-in-one feeder, since the power source used when loosening is air pressure, and it is generally used in conjunction with a punch press, vibration will inevitably occur. It is often the case that the relevant positioning screws of the three-in-one are loosened due to vibration. As for the leveling and feeding accuracy that is affected, when the material deviates, you can check whether the rollers are in a tight state. If the pressure is not enough, we can add more rollers.
