Home » Filter Bag Making Machines

This is a highly automated production system specifically designed for manufacturing industrial filter bags. Integrating multiple processes—such as sewing, hot-melt welding, and PTFE sealing tape application—the production line allows for flexible switching of manufacturing methods based on different filter media and process requirements, enabling the continuous, efficient, and high-quality production of filter bag bodies.


Description


The Advantage of Our Automatic Making Machine

  • The whole line can meet the production requirements of various processes such as sewing, gluing, hot welding, and PTFE taping.
  • This line is equipped with a brand-new fabric forming mold, which is suitable for sewing or welding of various specifications of filter bag body, with good forming effect and stable seam width.
  • The sewing machine includes an automatic stop device for automatic detection of broken threads, and automatic stop when abnormal thread breaks.
  • Adopt positioning device, precise film location; linkage work, automatic film application.
  • Special heating device, the temperature can reach 700℃, the temperature fluctuates ±2℃, which can be applied to the film sealing of pure PTFE filter bag.
  • This line includes a stripping machine and a film debris collection device, and no problem with membrane material hot welding.
  • This line’s work roller is covered with low-hardness polyurethane, which has good flexibility and is not easy to damage the PTFE membrane on the surface of the filter material.
  • The main body adopts aluminum profile structure, the installation is firm and the operation is stable.
  • This whole line is equipped with high-power cutter motors and alloy steel blades, which can easily cut PTFE and woven fiberglass filter bags.
  • Choose programmable control system, servo control system, frequency conversion control system, so the equipment failure rate is extremely low.
