In the production of large cards such as RFID traceability hang tags for apparel and smart access cards, simultaneous multi-label application presents serious challenges. Because the cards are large and their weight is unevenly distributed, multiple heads working at the same time are prone to positioning errors caused by material wobble or unstable feeding. To solve this industry pain point, Wanzhi Automation introduced the WZ-125G automatic four-head card labeling machine. With parallel labeling technology and a high-rigidity structural design, it effectively improves stability and accuracy when labeling multiple areas.
Analyzing the technical challenges of multi-head synchronous labeling of large cards
When multiple labels are applied simultaneously to large cards, such as RFID-embedded hang tags measuring 300mm to 600mm in length and width, the process is far more complex than for conventional small products. First, during high-speed conveying, cards without effective support easily deform slightly or drift, which leads to bubbles or crooked labels during application. Second, when 2 to 6 labeling heads press down and dispense labels at the same time, the instantaneous mechanical reaction forces add up; if the frame is not rigid enough, resonance occurs and directly disrupts the alignment reference. In addition, parallel multi-head operation demands extremely high synchronization among the feeding, loading, and collection mechanisms, and a jam at any point can stop the whole line or raise the reject rate. Breaking through the throughput bottleneck therefore depends on systematic optimization of both the mechanical structure and the control system.
WZ-125G parallel labeling technology and key parameters
To address these challenges, the WZ-125G automatic four-head card labeling machine developed by Wanzhi Automation has been deeply optimized in both structural design and motion control. The machine uses a heavy-duty elongated one-piece stainless steel frame with a dead weight of 900Kg, physically isolating resonance and vibration during high-speed material travel.
For the labeling module, the WZ-125G is equipped with a high-precision dual-side-supported labeling head. This design not only increases head stability but also ensures verticality during label dispensing, keeping positioning accuracy stable at ±0.5mm to meet the strict quality control requirements of RFID smart cards. In terms of throughput, maximum label dispensing speed reaches 60M/min; with 2 to 6 labeling heads working in parallel, the machine delivers about 1200 to 1600 cards/min, greatly increasing labeling speed and overall production efficiency.
In addition, the machine is equipped as standard with an automatic sheet separation and loading mechanism and a rear automatic stacking collection mechanism, enabling continuous unattended batch processing from loose materials to large cards. An independent industrial touch control panel supports independent adjustment of each labeling head’s parameters, ensuring precise execution under complex label layouts.
Practical selection considerations and applications
When selecting the WZ-125G, companies need to customize it according to actual card dimensions and label layout. The machine accommodates large cards from 300 to 600mm long and 300 to 600mm wide without modification. The number of heads uses a modular design and can be flexibly set from 2 to 6 heads according to order requirements, giving the machine high reusability.
The machine is mainly used in apparel RFID traceability, smart card manufacturing, furniture hang tag processing, and ID card printing. For volume production that requires applying multiple RFID inlay labels or anti-counterfeit labels to a single card at the same time, the WZ-125G can eliminate several line steps and save floor space and equipment investment.
FAQ
How many labeling heads can the WZ-125G be configured with at most?
The machine uses a modular head design that supports 2 to 6 labeling heads working in parallel, and customers can customize the number of heads according to their card label layout.
How does the machine keep large cards flat during material travel?
The WZ-125G is equipped with a high-precision dual-side-supported labeling module and a 900Kg heavy-duty stainless steel frame, effectively suppressing vibration and drift at high speed and keeping material travel stable.
Is setup complicated when switching between card sizes?
The machine has an independent industrial touch control panel that supports independent parameter adjustment for multiple heads and program storage. When switching card models, simply recall the stored program and make minor mechanical adjustments; setup is convenient.
