Vertical stuffing machine ensures the accuracy of the filling amount through a variety of precise designs and control methods.
First of all, in terms of mechanical structure, the filling pump of the stuffing machine is the key. Generally, a high-precision positive displacement pump is used, such as a gear pump or a screw pump. Taking the gear pump as an example, its working principle is to suck the filling from the hopper and deliver it to the filling head through a pair of meshing gears rotating in the pump cavity. The volume of filling delivered by each rotation of the gear is relatively fixed, which lays the foundation for accurate control of the filling amount. By accurately calculating and designing the size, number of teeth and volume of the pump cavity of the gear, the amount of filling delivered by each rotation can be highly consistent. The screw pump is similar. The parameters such as the pitch and diameter of the screw are precisely designed to ensure the stable delivery of the filling.
Secondly, the stuffing machine is equipped with an advanced control system. In the process of the motor driving the filling pump, a precise speed regulating motor is used. The speed of the motor can be accurately controlled through the electronic speed control system. The motor speed is directly related to the delivery volume of the stuffing pump. When the filling volume needs to be adjusted, the operator only needs to set the corresponding value on the operation panel, and the control system will adjust the motor speed according to the setting, thereby changing the delivery speed and filling volume of the stuffing. Moreover, during operation, the control system will continuously monitor the motor speed and correct the speed deviation in time through the feedback mechanism to ensure that the delivery volume of the stuffing is always kept within the set accuracy range.
In addition, the filling pipe of the stuffing machine also has an impact on the filling accuracy. The inner diameter size accuracy of the pipe is very high, and its smoothness is also specially treated to ensure that the filling will not produce flow fluctuations due to friction or inner diameter changes of the pipe during the delivery process. In the filling head part, the design of its outlet can ensure that the filling flows out evenly and stably, avoiding the filling volume error caused by splashing or uneven outflow of the filling.
Finally, in order to further improve the accuracy, some advanced Vertical stuffing machines are also equipped with weighing sensors. Weighing sensors are installed under the container filled with stuffing to measure the weight of the stuffing in real time. When the filling amount is close to the set value, the control system will fine-tune the delivery speed of the filling pump so that the filling amount can accurately reach the set value. This closed-loop control method greatly improves the accuracy of the filling amount. Through the above comprehensive measures, the Vertical stuffing machine can stably and accurately complete the task in the filling operation of various fillings.
