Automatic Double Side Corner Label Applicator

During operation, paper boxes can be fed manually or connected with an upstream production line. After conveying and product detection, the sensor identifies the box position and sends a signal to the labeling control system. The system then drives the labeling mechanism to dispense the label at the preset position, applying it to the required corner area of the box.

After initial application, the box passes through the rolling and brush pressing mechanisms, allowing the label to adhere firmly to both the top and side surfaces. This helps reduce edge lifting, bubbles, wrinkles, and weak adhesion. For boxes that require tamper-evident labels on both sides, the machine provides stable, continuous, and consistent double-side corner labeling.

The main advantages of the automatic double side corner label applicator are stable label positioning, neat sealing performance, and high production efficiency. The machine is specially designed for box corner labeling and combines top pressing with side brushing to ensure that labels wrap smoothly around the corner and remain firmly attached. The top pressing mechanism improves box stability during conveying, reducing shaking and position deviation during labeling.

The intelligent photoelectric detection system supports no-product-no-label operation and includes label detection and automatic correction functions, helping reduce missed labels and label waste. The machine uses a PLC control system and a touch screen interface, making operation clear and parameter adjustment convenient. It can be quickly set according to different box sizes, label specifications, and production speeds.

It is suitable for paper boxes with a length of 20–300mm, width of 50–200mm, and height of 25–300mm. The applicable label width is 20–130mm, and label length is 15–100mm, with customized specifications available according to samples. The labeling speed can be adjusted according to product size and label length, with a maximum capacity of 40–200 boxes per minute, making it suitable for medium- and high-speed packaging lines.

The automatic double side corner label applicator is widely used in printing and packaging, food, daily chemical, electronics, pharmaceutical, facial mask, playing card, gift box, and various paper box packaging industries.

It is suitable for tamper-evident labeling of playing card boxes, mobile phone packaging boxes, network card boxes, facial mask boxes, pharmaceutical cartons, and other sealed paper box products.

For manufacturers looking to improve box sealing label efficiency, maintain consistent label placement, reduce manual labeling errors, and enhance packaging security, the automatic corner label applicator provides a stable, practical, and production-line-friendly automatic double side corner labeling solution.
