Keqi Automatic Triangle Corner Labeling Platform | High Precision Carton Corner Label Applicator

Many packaging factories still finish triangular corner label attachment by manual work. This mode brings slow throughput, inconsistent sticking accuracy and heavy labor expense. Misplaced, wrinkled and skewed labels will lower packaging grade and raise reject volume during quality inspection.

Dongguan Keqi Automation launches the professional triangle corner labeling machine specially designed for carton edge triangular sticker lamination.It adopts vacuum separation paper feeding system to separate carton sheets one by one and eliminate double-feeding jamming. Servo-controlled labeling unit completes label peeling, positioning and right-angle folding pasting in one cycle, making triangular labels tightly fit box corners with no offset or bubbling.

The touchscreen control panel supports customized setup of label dimension, pasting pitch and operating parameters. The equipment features two optional working modes: rotary labeling with a conveyor speed up to 25 m/min, and direct labeling supporting a maximum conveyor speed of 40 m/min. The 1800 pieces per hour output shown in the case is the parameter set by this specific customer’s production task. Modular mechanical design enables quick format changeover to fit various carton sizes.

Key motion and positioning parts use industrial grade components to sustain long-term nonstop mass production. Replacing manual labeling with this automated unit standardizes finished product quality, slashes labor cost and cuts material loss from defective labeling.

We supply on-site installation, parameter commissioning and lifelong after-sales technical support. For packaging manufacturers seeking automated corner labeling solutions, Keqi triangle labeling equipment is an ideal upgrade to streamline your packaging workflow.
