The ST-500 easy-to-tear labeler produced by Tianjin Qibang Technology Development Co., Ltd. is primarily designed to address the issues of products being difficult to tear after heat shrink packaging or the danger of using tools to remove the film, which can scratch the products. Its features include: 1. Photoelectric distance measurement for automatic label application; 2. Stepper motor drive for precise and stable operation; 3. Integration with plastic sealing machines for accurate label application after book plastic film punching; 4. Variable frequency motor speed that can automatically match the stepper motor speed and can also be freely adjusted; 5. When not in use for label application, the equipment can be used as a conveyor belt.
