The fertilizer quantitative packaging scale is specially designed for the quantitative packaging of fertilizer products.

The fertilizer quantitative packaging machine is specially designed for the quantitative packaging of fertilizer products. Since all aspects are still in the initial stage of development, the technical level of the equipment is not fully mature, and some problems still occur in the actual packaging process. Appropriate improvements to the packaging scale.

For example, the material in the bag mouth of the fertilizer quantitative packaging scale has large dust, mainly because the distance between the feeding port of the weighing hopper and the bag holder is relatively large, so that the material generates dust at the mouth of the bag under the action of gravity, and the splashed material affects the labor force. The health of the baggers and the drop of potash fertilizers also increase the workload of the workers.

In order to overcome this difficulty, a secondary cutting device composed of a cutting plate, a cylinder and a solenoid valve is installed between the discharge transition bins of the fertilizer quantitative packaging machine, which not only slows down the gravitational potential energy generated by the falling of materials, but also reduces the The amount of material splashing out can alleviate the pollution and corrosion of the surrounding accessories, and at the same time reduce the failure links of the fertilizer quantitative packaging scale, improve the packaging output, and correspondingly reduce the labor intensity of operators.

Sometimes, the weighing hopper leaks in the fertilizer quantitative packaging scale, which is related to the wear of the weighing hopper and the aging of the sealing strip, which seriously affects the measurement accuracy. In response to this situation, stainless steel materials were used to improve the sealing of the weighing hopper of the fertilizer quantitative packaging scale in the later stage, so that there was no need to replace the sealing strip from time to time, and the leakage phenomenon basically disappeared.

In addition, the designers also improved the counter of the fertilizer quantitative packaging scale, sending signals to the counter through the relay on and off to the digital module, uploading it to the upper computer through PLC communication, and moving the counter to the upper computer system screen. In this way, there is no need to shuttle back and forth between the control room and the power distribution room, and the work tasks are intuitively and clearly grasped.

One of the frequently encountered problems is that the pneumatic actuator of the packaging scale is stuck and the action is not in place. The analysis proves that this is caused by the high moisture content in the compressed air during the packaging process. In this case, it is necessary to replace the engineering molecular sieve in the packaging scale, and to drain the air supply triplet regularly, and don't forget to regularly add grease to the actuator.

If the solenoid valve of the packaging scale fails, it will cause the PLC signal output of the equipment, and the solenoid valve body will be stuck, causing the actuator to not act. This also reminds the majority of users that they must regularly check the action of the solenoid valve in the packaging scale, and disassemble and clean the valve body in time and add grease.

There is also a problem that when the start button of the packaging scale is pressed, the large and small material doors cannot be opened, and material feeding cannot be performed. Analysis proves that the reason for this phenomenon is that the packaging scale has not been used for a long time, and there is still a certain amount of finished products in the hopper, which causes this phenomenon to occur.

When encountering a similar situation, the first is to clear the hopper of the packaging scale, and then clear the value of the instrument to zero. In order to avoid the recurrence of this phenomenon, if the packaging scale is not used for a long time, the hopper must be cleared in time to keep the empty warehouse.
