Key Advantages
- The machine adopts an intelligent control system with automatic photoelectric tracking, including label sensing and automatic deviation correction. It only applies labels when products are detected, greatly reducing label waste and avoiding missing labels.
- Driven by high-performance servo motors for labeling and conveying, it supports separate double‑sided labeling, ensuring stable running, high positioning accuracy, and efficient production up to 80 rolls per minute.
- Sliding rail structure allows stepless adjustment of material width and roll diameter, enabling fast changeover and accurate positioning for different packaging sizes.
- The waste rewinding part uses a magnetic particle clutch to maintain stable tension, effectively preventing the backing paper from breaking during operation.
- Made of heavy‑duty A3 steel and high‑grade aluminum alloy, the machine features a solid, durable structure with an elegant appearance.
- Double‑sided plastic synchronous guide rails are adopted to reduce scratches on products and make operation easier for workers.
- Equipped with a continuous pressing mechanism to ensure labels stick firmly and do not fall off. An automatic spacing device ensures stable product conveying and precise labeling position.
- Multi‑functional design realizes both single‑sided and double‑sided labeling for various products on one machine.

Equipment layout

- How do you guarantee the quality and stability of your machines?
A: Every unit undergoes strict full-load performance testing prior to delivery. Customers can supervise the test on-site or via real-time video. We only use reliable branded core parts, along with comprehensive operating guides and ongoing remote technical assistance to maintain consistent performance.
- We have little experience in automated equipment. What support can you provide?
A: We offer full turnkey solutions covering production line layout, on-site operator training, machine installation and commissioning, and professional guidance as agreed in the contract. Remote diagnosis and on-site service are also available when needed.
- Is your equipment suitable for frequent product size switching?
A: Absolutely. With a modular structure and built-in parameter storage system, our machines allow quick format changeover (time varies by model and product). Custom tooling can also be provided to fit your specific product dimensions.
- We have little experience in automated equipment. What support can you provide?
