Causes and Solutions of Zero Point Drift of Dynamic Checkweigher
Dynamic checkweigher machine is a relatively common online testing equipment in the market. It realizes automatic weighing and sorting according to the weight level of the set product. It is an efficient, intelligent and convenient comprehensive solution! We are using dynamic checkweigher. There will be some problems when weighing scales. The most common one is zero drift. If we want to solve the problem of zero drift of the checkweigher machine, we must first understand the causes of the zero drift of the checkweigher and fundamentally solve the zero drift of the checkweigher. Fault. The reasons for the zero drift fault of the dynamic checkweigher machine: 1. The components are blocked 1) The load cell is faulty. When the load cell is aging, the output signal is unstable or has errors, which will lead to the appearance of zero drift. 2) The speed sensor is faulty. The speed sensor is the same as the load cell, if the output signal is unstable, it will lead to zero drift. 3) The weighing instrument is faulty. The aging of the weighing instrument will cause measurement errors and zero-point drift of the belt scale. 2. There is a problem with the belt conveyor. 1) There is material on the belt conveyor. If the humidity of the material transported by the belt conveyor is too high, some materials will stick to the conveyor, which will cause the zero point drift of the belt scale. 2) The belt tension is unstable. The tension of the belt is not enough, the belt is slack, and the belt tension is unstable, both of which will cause the zero-point drift phenomenon. 3) Belt deviation. Belt deviation will make the belt scale unstable during weighing, resulting in zero point drift of the belt scale. How to solve the zero drift fault of the dynamic checkweigher: 1. Regular cleaning: When we use the checkweigher, there will be dust and falling objects from the weighing object. We need to clean the checkweigher in time so that we can check the weight. The scale is not affected by external garbage objects and causes zero drift failure during work. 2. Check the checkweigher: When we use the Dongguan checkweigher, we should be used to starting the check, because if there is a large piece of material stuck in the checkweigher, we must clean it up in time, otherwise it will bring our weighing. influences. 3. Detection and replacement of electronic components: When the zero-point drift failure of the checkweigher occurs, there is another reason that there may be a problem with the electronic components of the checkweigher. Damage to the electronics when the scale's sensor is severely overloaded is one of the reasons.
