Machine Description
The bottom gluing machine is an automated device specialized for forming and gluing paper bag bottoms. It achieves a sealed bottom by precisely controlling the adhesive application, bottom stretching and positioning, and heat-pressing curing processes. It is primarily used in the production of clothing packaging, food packaging, shopping bags, and other fields.
By utilizing high-speed, high-precision production processes and intelligent control systems, it reduces costs, improves efficiency, and optimizes quality. Its modular design allows for flexible adaptation to diverse production needs. Its environmentally friendly features align with current trends in green production, making it a leading upgrade option for traditional paper bag production equipment.
Machine Features
Efficient Automated Production: Continuous working mode integrates the entire process of bag feeding, glue spraying, and pressing, significantly improving efficiency and reducing manual dependence; touch screen control + PLC programming system enables one-click parameter adjustment.
Precise Control and Stability: Fiber optic sensors monitor glue volume and position in real time, with an accuracy of ≤±200g.
Flexible Adaptability: Exchanging molds allows for adaption to various bag shapes (such as square bottoms, pointed bottoms, and valve bags).
Supports a variety of materials: kraft paper, coated paper, paper-yarn composite bags, and more.
Environmentally friendly and low-energy design: Biodegradable hot-melt adhesive reduces pollution; energy-saving components (such as a variable-frequency motor) reduce energy consumption, reducing glue consumption by 30% compared to traditional manual primer application.
Smart maintenance and durability: The modular structure facilitates replacement of key components, and the self-diagnosis system provides real-time warning of electrical faults (such as motor overheating and glue line blockage).
