How to Adjust Filling Accuracy of Linear Oil Filling Machines
The filling quantity can be controlled by a timer. This method is easy to realize the adjustment to filling accuracy, but the error is also great. And the error is mainly caused by temperature and program structure. The MCU works by the frequency output of the crystal oscillator, and the temperature has an influence on the frequency of the crystal oscillator. A good crystal oscillator can minimize the influence of temperature but can't not eliminate it. This influence directly determines the time base of the timer in the MCU and thus affect the set time length, resulting in working time inconsistency of the edible oil filling machine every time and contributing to errors. In addition, it is not advisable to use the program to generate the time value accurately. During operation of the machine, various interrupt operations will lead to the time error, which cannot be measured and compensated.
Use the number of pulses to control the filling quantity. This method can ensure that the total number of angles, operated by the edible oil filling machine in each distribution, is the same. And the filling accuracy is much improved. However, when the roller stops, its position is inconsistent with the position after the previous distribution. In this way, the distribution error will be caused by different stopping positions of the roller every time. This distribution error has a relatively small impact on the distribution of larger liquid volume, and mainly has a great impact on the distribution of smaller liquid volume.
For a user, besides knowing how to use the linear edible oil filling machine, you should also know the simple maintenance method of the machine, so as to improve the efficiency of the routine production and achieve the expected results.
