In the field of industrial packaging, the "character difference" of materials often becomes an invisible killer of production efficiency. From viscous jelly like asphalt to volatile liquids as active as springs, from suspensions with hidden particles to pastes that agglomerate when cold, traditional liquid packaging machines often fall into trouble due to "not adapting to the local environment". And ply-pack's intelligent liquid packaging system is reconstructing packaging logic through technological innovation.
When a biopharmaceutical company brought collagen stock solution with a viscosity of over 12000cPs to the door, the screw of the conventional liquid packaging machine had already started to slip. The technical team adopted a two-stage progressive pressurization scheme. The front spiral crushed the colloidal structure at a low speed, and the rear precision screw implemented constant pressure propulsion, and the flow resistance was reduced by cooperating with a 52°C constant temperature flow channel. This "break the whole into parts" treatment method has increased the hourly filling efficiency to 85% of the standard viscosity material.
In the daily chemical industry, the packaging of flavors with excessive fluidity has caused 3%-5% material loss. The R&D team was inspired by the biological behavior of dragonflies skimming the water and developed an air pressure compensation filling head. When the filling nozzle is lifted, the 0.05MPa negative pressure airflow forms a temporary sealing film, and the surface treatment of the nano-liquid repellent coating successfully controls the dripping volume within 0.01ml. The actual measurement data of a perfume OEM factory shows that this technology can reduce the waste of raw materials worth more than 2 million yuan each year.
In the face of the packaging needs of health drinks containing wolfberry particles, traditional equipment often has the problem of uneven particle distribution. Ply-pack's solution is a dynamic perception-adjustment system: it uses a high-frame-rate visual sensor to capture the trajectory of particle movement, adjusts the inclination of the V-shaped guide groove in real time, and controls the distribution dispersion of solid matter below 5mm in particle size within ±8%. This system has now been extended to more than 20 special material scenarios, including fruit pulp drinks and Chinese medicine concentrates.
The conductive silver paste packaging line designed for a nanomaterial company fully demonstrates the advantages of modular customization. In view of the easy agglomeration characteristics of silver paste, the production line integrates an ultrasonic dispersion module; in response to the requirements of conductive performance, all contact parts are upgraded to ceramic materials; combined with the customer's small-batch production needs, a fast changeover structure design is adopted. This "building block" construction mode shortens the delivery cycle of special orders to 70% of conventional projects.
On the monitoring screen of the packaging workshop, the real-time jumping data stream is interpreting the evolution of the intelligent liquid packaging system. From being forced to adapt to material characteristics to actively parsing flow codes, liquid packaging machines have broken through physical limitations and become a smart link connecting products and markets. When the last equipment completed factory inspection, the technical director wrote a note on the acceptance form: Real industrial packaging should not be a confrontation between materials and machinery, but a dance between technology and demand.
