80700 Series Double Needles Chain Stitch Sewing Machine-Hebei Longsew

The 80700 Series double needles chain stitch sewing machine is a cornerstone in the production of FIBC (Flexible Intermediate Bulk Containers) bags, also known as jumbo bags or big bags. Engineered for heavy-duty applications, this machine is designed to meet the rigorous demands of industrial manufacturing. With its advanced features and customizable options, the 80700 series ensures precision, efficiency, and durability in sewing processes. This article provides a comprehensive overview of the product’s functionality, technical specifications, applications, and the company behind it.

The 80700 Series is a specialized sewing machine tailored for the FIBC bag manufacturing industry. It is available in three primary versions: the 80700C (single needle), 80700CD (double needle), and the advanced 80700CD4H (double needle with additional features). Each model is designed to handle the unique requirements of jumbo bag production, offering flexibility in functionality and performance.

One of the standout features of the 80700 series is its ability to accommodate various configurations. Users can choose between single or double needles, flat beds or cylinder beds, and pneumatic or manual foot lift systems. Additionally, the machine can be equipped with either a hot cutter or manual cutter, depending on the specific needs of the production process. This adaptability ensures that the machine can be optimized for different types of FIBC bags, from standard to high-performance variants.

The machine’s robust construction is complemented by a powerful motor capable of handling materials up to 18mm in thickness. This makes it ideal for sewing heavy-duty fabrics used in FIBC bags, which are often subjected to significant stress during transportation and storage. The inclusion of a filler cord function further enhances its utility, allowing for seamless integration into automated production lines.

The 80700 Series is equipped with a range of advanced features that set it apart from conventional sewing machines. The 80700CD4H variant, in particular, is designed for high-volume production and includes several optional functions that enhance its performance:

• Pneumatic Foot Lift System: This feature allows for smooth and efficient operation, reducing manual effort and increasing productivity.
• Hot Cutter System: Ensures clean and precise cuts, minimizing the risk of fraying or damage to the fabric.
• Spout Type Table Top and Stand: Designed for specialized applications, this feature facilitates the sewing of bags with spouts or other custom configurations.
• Servo Motor: The use of a servo motor provides precise control and energy efficiency, making it suitable for demanding industrial environments.

The 80700CD4H also includes a needle position fixed up system and needle cooling system, which are critical for maintaining consistent stitching quality and extending the machine’s operational life. These features are particularly beneficial when working with high-strength materials that generate significant heat during the sewing process.

For users who require a more basic model, the 80700C and 80700CD variants offer essential functionality with the option to choose between a clutch motor or a servo motor. This flexibility allows manufacturers to select the most cost-effective solution without compromising on quality.

The 80700 Series is engineered to deliver exceptional performance, as outlined in the following specifications:

The specifications highlight the machine’s ability to handle heavy-duty tasks while maintaining precision and efficiency. The S.S. 304 (stainless steel 304) construction in the 80700CD4H variant ensures durability and compliance with high-standard manufacturing requirements, such as those in the food and pharmaceutical industries.

The 80700 Series is widely used in the production of FIBC bags, which are essential for transporting bulk materials in industries such as agriculture, construction, and logistics. These bags are designed to hold large quantities of goods, ranging from powders and granules to liquids, and require robust stitching to withstand harsh conditions.

The machine’s versatility allows it to be employed in various applications, including:

• Standard FIBC Bags: Used for general-purpose bulk material transportation.
• Custom-Designed Bags: Tailored for specific industries, such as those requiring food-grade or chemical-resistant materials.
• High-Volume Production: The 80700CD4H variant is ideal for manufacturers needing to produce large quantities efficiently.

Additionally, the machine’s compatibility with hot cutter systems and spout type table tops makes it suitable for specialized applications where precision and customization are paramount. This adaptability ensures that the 80700 series remains a preferred choice for manufacturers seeking to meet diverse market demands.
