Automatic non-woven bag making machine: an efficient solution for the modern packaging industry

As a key piece of packaging machinery, automatic non-woven bag-making machines have garnered increasing attention and adoption in recent years, driven by growing demand for environmentally friendly packaging. These machines, designed to automatically process non-woven materials into various types of bags, offer high production efficiency and consistent product quality, making them a key component in enhancing the competitiveness of non-woven product manufacturers. This article will delve into the operating principles, technical features, application areas, and future development trends of these machines.

Working principle and technical characteristics of non-woven automatic bag making machine

The automatic non-woven bag making machine is an automated equipment that integrates mechanical, electrical and pneumatic functions. Its basic working principle is to automatically complete the processes of unwinding, correcting deviation, folding, sealing, cutting, and bagging the rolled non-woven fabric raw materials through a series of precise mechanical actions, and finally produce finished bags.

The equipment's workflow typically begins with the unwind mechanism, where large rolls of nonwoven fabric are loaded. This advanced unwind system, equipped with automatic tension control, ensures the material remains flat and stable as it enters the processing area. The material then passes through a photoelectric web guide, which monitors the material's position in real time and automatically corrects it to ensure accurate subsequent processing.

Next, the material enters the folding process. Depending on the bag design, the equipment will fold the material into the required shape through a specific folding mechanism. For T-shirt bags, this step includes side folding and bottom folding; for flat bags, it may only require a simple folding process.

The sealing and cutting process is the core of a non-woven bag-making machine. The heat-sealing mechanism fuses and seals the non-woven material at specific locations through precisely controlled temperature, pressure, and time. Simultaneously, the cutting device precisely cuts the bag to a preset length, forming individual bags. Modern high-end equipment often utilizes servo drive systems to ensure precise sealing and cutting positions, with errors controlled to within millimeters.

Finally, the finished bags are conveyed out via a conveyor belt. Some equipment is also equipped with automatic counting and stacking functions to further reduce manual intervention and improve production efficiency.

The technical characteristics of the non-woven automatic bag making machine are mainly reflected in the following aspects:

1. High degree of automation : From raw materials to finished products, the entire production process requires almost no human intervention, greatly reducing labor intensity and dependence on operator skills.
2. High production efficiency : The operating speed can reach 60-120 bags per minute or even higher, depending on the bag type and material properties.
3. Strong flexibility : By changing the mold and adjusting the program parameters, the same equipment can produce non-woven bags of various specifications and styles, such as flat bags, T-shirt bags, handbags, button bags, etc.
4. Excellent precision control : Adopting servo motor and PLC control system to ensure the consistent size of each bag and the firm and beautiful seal.
5. Energy saving and environmental protection : Modern non-woven bag making machines mostly use high-efficiency heating technology and energy-saving motors to reduce energy consumption and comply with the concept of green manufacturing.

Application areas of non-woven automatic bag making machines

The bags produced by the non-woven automatic bag making machine are widely used in many fields due to their environmental protection, durability and aesthetics:
