Description
The tin can labeling machine automatically applies labels to sealed tinplate cans that enter the equipment in sequence. It works either as a standalone unit or in a production line, with two models for different can sizes: ENKG-01 (small cans) and ENKGD-01 (large cans), both designed for easy packaging and storage.
Simple to operate and master, the machine allows quick adjustments for various can types. It cuts labor demand and intensity significantly while boosting enterprises’ production line management. Engineered for high speed, stability, and space efficiency, it adapts to multiple tinplate can specifications, offering strong versatility.
Application Scope
This machine is exclusively for labeling tinplate cans, suitable for industries like food, beverage, chemical, and pharmaceutical where tinplate cans are common packaging. It works with sealed tinplate cans of different shapes (e.g., cylindrical, oval) and sizes within its adjustable range.
Core Feature: Servo Electric Cylinder for Label Feeding
A key advantage is its servo electric cylinder label-feeding system. Unlike traditional mechanical setups, it enables precise label delivery, ensuring accurate placement (reducing misalignment) and stable long-term operation. The servo system minimizes wear, lowers maintenance needs, and maintains consistency even at high speeds, solving issues like label jams in conventional machines.
Process Flow
The machine integrates automated functions like automatic feeding and labeling for a smooth workflow:
Loading: Cans are manually placed on the feeding conveyor or auto-loaded via a full-can depalletizer (for large lines).
Sorting & Lifting: A turntable arranges cans into a single row, which then go up a belt elevator.
Coding (Optional): An ink jet device prints production/batch dates on cans during lifting.
Orientation Adjustment: A tumbling cage flips cans to align the labeling area.
Gluing & Labeling: Pressure belts rotate cans; hot melt adhesive is applied as they pass the glue station. The servo-fed label’s leading edge sticks to the glued area, wrapping around the can. A mechanism adds glue to the label’s tail for secure bonding.
Pressing & Collection: Pressure belts press the label to remove bubbles. Cans are flipped back via another cage and sent to the circulating collection line, which connects to auto-cartonning/palletizing for full automation.

Advantages
1. Compliant & Durable Materials
The machine is built with a high-quality material mix: stainless steel (ideal for food/pharma due to easy cleaning), aluminum alloy (lightweight yet sturdy), engineering plastics (wear-resistant), and coated carbon steel (anti-rust). These materials fully meet national safety and hygiene standards, resisting residue buildup and corrosion—perfect for humid or dusty workshop environments where equipment longevity is critical.
2. Space Efficiency & Cost Reduction
Its compact design (max length 2300mm for the large-can model) significantly saves floor space, fitting well in small-to-medium factory layouts. Unlike traditional setups, it integrates pre-labeling conveying functions, eliminating the need for extra multi-section conveyors. This not only cuts space usage but also reduces overall production line investment by 10-15%, easing financial pressure on SMEs.
3. Non-Stop Labeling for Higher Efficiency
Equipped with two independent servo label-feeding mechanisms, the machine enables alternate operation. When one label roll runs low, operators reload the other without pausing production—avoiding downtime and boosting overall efficiency by 15-20%. Note: This function excludes labels <35mm wide, as narrower labels require ultra-precise alignment that alternate feeding can disrupt.
4. Smart Glue Control to Cut Waste
High-sensitivity photoelectric sensors control the glue system, triggering hot melt adhesive supply only when a can is detected. No cans mean no glue flow, reducing adhesive waste by 8-12% yearly and preventing glue drips that could contaminate cans or damage the machine, thus lowering maintenance needs.
5. Quick Can Type Changeover
Switching between can sizes (from 30g spice cans to 4200g industrial cans) takes just 15-30 minutes. It only requires simple adjustments (e.g., pressure belt height via the control panel) and minimal part replacement (e.g., small guiding rails), letting the machine adapt fast to multi-product lines and enhancing production flexibility.
6. Reliable Servo Motor Performance
Powered by Inovance servo motors—renowned for industrial reliability—this machine runs stably 24/7 without overheating. The motors operate at <60dB (low noise for a better workshop environment) and consume less energy, slashing long-term electricity costs while maintaining precise label feeding for consistent labeling quality.
