Weighing and filling belongs to the terminal intelligent measurement control technology, which is not affected by temperature and has high accuracy. The process can be monitored and feedback in real time, and the advantages of product safety and equipment efficiency are outstanding. It has gradually become the new mainstream in the field of filling. Indicators such as valve dripping, filling accuracy, bottle splashing, and intelligent filling process are important basis for judging the quality of liquid filling machines. In recent years, Jiangsu Yiminuo Packaging Machinery Co., Ltd. has increased its research and development efforts, innovated the intelligent control system of filling valve and filling weighing, and greatly improved the performance of the filling machine.

The dual-stroke cylinder drive and the unique slow-flow core wing design realizes slow→fast→slow or fast→slow dual flow rate combined stable and accurate filling, which improves the filling accuracy. The slow-flow core wing structure inside the filling valve has the function of diverting and slowing the flow of liquid materials, making the filling process smooth and smooth. The structure is integrated with the filling valve core, on the side close to the terminal end of the valve head. When the cylinder drives the filling valve core, the core wing structure slides up and down along the inside of the valve seat, which can play a good centering and guiding role, and the liquid column is vertically aligned with the middle of the bottle mouth, which significantly improves the filling quality. When the valve is closed, the upper sealing method can realize the centering of the valve head sealing body and the valve seat without offset and sealing, and the extrusion impact of the valve closing action on the material is reduced to a small extent. Switching to slow filling before closing the valve, coupled with the diversion and slow flow effect of the core wing structure on the material and the guiding effect of the valve core, can fundamentally solve the problem of instant material splashing when the valve is closed.

Some liquid materials themselves have viscosity, which is easy to collect and drip at the filling valve port and contaminate the table. The previous measure is to add a vacuum channel, but the effect is not good and the pollution still exists. The new design is equipped with an adsorption device at the end of the valve port. Using the principle of siphon and liquid surface tension, the material in the valve head is adsorbed before it gathers into droplets, so that the accumulated material in the valve head is reduced to the point where it is difficult to form a droplet, and the gravity of the attachment is not enough to overcome The valve head seals the surface tension of the liquid itself to prevent dripping.

The electronic scale is a precision instrument with its own safety overload range, so it is necessary to attach great importance to its safety protection device. The newly developed guard plate device can automatically unload and protect when it is impacted, which avoids the impact on the electronic scale, and also protects the bottle to ensure the safety of filling. When the bottle is not in place, the two unloading springs of the guard plate can instantly release the impact force on the guard plate and the squeezing force on the bottle.

In terms of electrical control, encoders and valve islands are used in conjunction with load cells to realize the intelligence of the entire filling process. Intelligently verify whether the entire filling process conforms to the set filling flow rate, manage the switching point of the filling valve, and optimize and collect filling data. Touch screen control, easy operation and high degree of automation. Features also include: no bottle, no filling; online detection of filling accuracy, continuous out-of-tolerance alarm; different parameter formula storage of different bottle types and filling products; online shielding of fault filling valves, shielding valves do not enter bottles; fault self-diagnosis function, it can automatically stop and prompt the fault point in case of failure.
