FIBC Sewing Machine-HEBEI LONGSEW|Chain Stitch Precision, Heavy-Duty Durability



Introduction to FIBC Bags and the Role of Industrial Sewing Machines

FIBC (Flexible Intermediate Bulk Containers) bags are essential in industries such as agriculture, construction, and chemical manufacturing, offering a cost-effective and durable solution for bulk material storage and transportation. The production of these large, heavy-duty bags requires specialized machinery capable of handling thick materials and ensuring consistent, high-quality stitching. The 80700 series chain stitch sewing machine, developed by HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD, is a leading solution in this domain. This article explores the 80700 series sewing machine, its technical specifications, applications, and the company's expertise in industrial textile machinery.

Product Overview: The 80700 Series Chain Stitch Sewing Machine

The 80700 series sewing machine is a cornerstone in the production of FIBC bags, designed to meet the demanding requirements of heavy-duty fabric manufacturing. This machine is available in three primary models: the 80700C (single needle), 80700CD (double needle), and the advanced 80700CD4H (with additional features). Each model is tailored to specific production needs, offering flexibility in needle configuration, bed type, and optional functions.

The machine's robust construction and powerful motor make it ideal for sewing thick materials, such as woven polypropylene, which is commonly used in FIBC bags. Its design emphasizes efficiency, precision, and durability, ensuring long-term reliability in high-volume manufacturing environments.

Technical Specifications: Precision Engineering for Industrial Use

The 80700 series sewing machine is engineered to deliver exceptional performance in heavy-duty applications. Below is a detailed technical specifications table:

Model Needle Configuration Motor Type Max Thickness Stitch Range Speed Additional Features
80700C Single Needle Clutch or Servo 18mm 6-12mm 1400 rpm Basic Functionality
80700CD Double Needles Clutch or Servo 18mm 6-12mm 1400 rpm Basic Functionality
80700CD4H Double Needles Servo 18mm 6-12mm 1400 rpm Pneumatic Foot Lift, Hot Cutter, Needle Cooling

The 80700CD4H model, in particular, stands out with its advanced features, including a pneumatic foot lift system, hot cutter system, and needle cooling system, making it suitable for high-precision, high-volume production. The use of a 220V servo motor ensures energy efficiency and consistent performance.

Key Features and Advantages

The 80700 series sewing machine offers a range of features that enhance productivity and quality in FIBC bag manufacturing:

  • Double Needles for Efficiency: The double needle configuration allows for simultaneous stitching, significantly reducing production time and increasing output.
  • Adjustable Stitch Range: With a stitch range of 6-12mm (standard 10mm), the machine accommodates various fabric thicknesses and stitching requirements.
  • Top and Bottom Feeding: Ensures even fabric movement during sewing, preventing puckering and ensuring consistent stitch quality.
  • Filler Cord Guides: These guides help maintain tension and alignment of the filler cord, crucial for the structural integrity of FIBC bags.
  • High-Speed Operation: Capable of up to 1400 rpm, the machine supports high-volume production without compromising quality.
  • Robust Construction: The stainless steel table top and body are designed for durability and resistance to corrosion, making them suitable for food-grade and chemical environments.

The 80700CD4H model further enhances these features with a pneumatic foot lift system, which automates the lifting of the presser foot, and a hot cutter system for clean, precise cuts without manual intervention.

Applications in FIBC Bag Manufacturing

The 80700 series sewing machine is specifically designed for the production of FIBC bags, which are used in industries requiring bulk material handling. Its applications include:

  • Bag Body Assembly: The machine efficiently sews the main body of the bag, ensuring strength and durability.
  • Spout and Handle Installation: The spout type table top and stand option facilitates the installation of spouts and handles, streamlining the production process.
  • Reinforcement Stitches: The machine's ability to handle thick materials makes it ideal for reinforcing critical areas of the bag, such as seams and corners.
  • Customization: With options for different needle configurations and bed types, the machine can be tailored to produce bags of varying sizes and designs.

The 80700CD4H model is particularly well-suited for high-precision applications where needle position fixed up system and needle cooling system ensure consistent stitch quality and prevent overheating during prolonged use.
