In fresh egg processing and packaging, surface labeling of blister packs is an important step for traceability and brand presentation. Yet manual placing and collecting is slow and laborious, and hard to match the capacity of high-speed thermoforming lines. How can this bottleneck be broken? The Wanzhi Automation WZ-160 automatic egg carton labeling machine, with its fully automatic loading and unloading, offers a new approach to upgrading egg packaging lines.
Efficiency pain points in conventional egg labeling and the automation solution
On conventional egg packaging lines, labeling is often the efficiency weak point. Operators place cartons one by one, label them and then stack them by hand; labor costs are high and fatigue easily causes missing or crooked labels. To address this, Wanzhi developed the WZ-160 automatic egg carton labeling machine. It integrates robotic carton picking and separating with automatic stacking collection of finished products. A full stack can be loaded at once, the magazine holds 70 cartons (an extended magazine holding 100 is optional), and after labeling the cartons are palletized automatically, collecting up to 50 at a time, truly moving from manual assistance to unattended continuous production.
WZ-160 technical analysis and parameter advantages
As a professional automatic labeling machine, the WZ-160 performs well in labeling accuracy and running stability. It carries a high-accuracy flat-surface labeling head and photoelectric tracking system, so cartons travel steadily without drift and labeling registration stays within ±1mm, keeping fresh-produce traceability labels flat with no wrinkles or bubbles. On output, maximum conveying speed reaches 16m/min and stable capacity is 25-45 cartons/min. Conveyor width is adjusted electrically, so 8-count to 30-count egg blister packs can be switched quickly without major modification. The independent touch screen industrial PC allows separate adjustment of labeling speed, label feed length and conveying spacing, and the all-stainless-steel frame is solid enough to reduce vibration at high speed.
Line integration advice and applications
In production, the WZ-160 integrates readily with different lines. For a standalone packaging workshop, it can run on its own, with one operator supervising several machines; for companies with an upstream thermoforming machine, it can connect directly to the thermoforming line for automated forming and labeling, greatly saving floor space and labor costs. When selecting, configure a standard or extended magazine according to actual daily output and workshop layout. For maintenance, the stainless steel frame is easy to clean and meets hygiene standards for the fresh-food industry, and we recommend using consistent, good-quality pressure-sensitive labels to get the best from the machine.
FAQ
Which egg carton specifications can the WZ-160 handle?
Conveyor width is electrically adjustable, fully compatible with 8-count to 30-count egg blister packs and some fresh fruit plastic trays; switching specifications needs no major modification, so the machine is highly reusable.
How does the machine support unattended continuous production?
The machine is fitted with a robotic carton picking and loading mechanism and an automatic stacking collection mechanism. Each load holds 70 cartons and collection stacks 50, greatly extending the interval between reloading and collection and reducing manual intervention.
What affects labeling capacity?
The WZ-160’s stable capacity is 25-45 cartons/min. Actual capacity varies slightly with carton size, label length and upstream feed speed: larger cartons and longer labels increase the time per carton.
