Spiral Helical Cylindrical Gear Grinding For Compound Feed Lockstitch Sewing Machine

Sewing M/C Cylindric Helical Gear For Compound Feed Lockstitch Sewing Machine

Cylindrical gears play a significant role in the compound feed lockstitch sewing machine's power transmission system, particularly in driving the feed mechanism. Here are the key roles and functions of cylindrical gears in a compound feed lockstitch sewing machine:

• Feed Dogs: Cylindrical gears are used to drive the feed dogs, which are responsible for gripping and advancing the fabric during the sewing process. The gears transmit rotational motion from the main drive shaft to the feed dog mechanism, ensuring smooth and synchronized feeding of the fabric.

• Needle Feed: Cylindrical gears are also involved in driving the needle feed mechanism. The needle feed mechanism consists of a set of teeth that engage the fabric and help move it along with the needle. Cylindrical gears transmit power from the main drive shaft to the needle feed mechanism, providing controlled movement of the fabric during the stitching process.

• Walking Foot: In some compound feed lockstitch sewing machines, a walking foot mechanism is utilized to provide additional feeding assistance for thick or difficult-to-handle materials. Cylindrical gears are employed to drive the walking foot mechanism, ensuring even and consistent movement of the fabric during stitching.

• Power Transmission: Cylindrical gears are crucial for transmitting power from the machine's motor to various components in the feed mechanism. They maintain the torque and rotational motion necessary to drive the feed dogs, needle feed, and walking foot, enabling the machine to sew through different fabric thicknesses effectively.

A compound feed lockstitch sewing machine is a type of sewing machine commonly used in industrial settings for heavy-duty sewing tasks. It is designed to handle a wide range of materials, including thick or layered fabrics, leather, upholstery, and other heavy fabrics. Here are some key features and characteristics of a compound feed lockstitch sewing machine:

• Compound Feed Mechanism: The compound feed mechanism is a distinctive feature of this type of sewing machine. It involves three feeding components working together to ensure smooth and even fabric feeding. These components typically include the feed dogs, needle feed, and walking foot. The feed dogs grip and move the fabric from the bottom, while the needle feed mechanism moves the fabric in coordination with the sewing needle. The walking foot, also known as a top feed, further assists in feeding multiple layers of fabric evenly.
• Lockstitch Formation: Compound feed lockstitch machines produce a lockstitch, which is a strong and secure stitch commonly used in sewing applications. The lockstitch is formed by the upper thread from the sewing needle interlocking with the lower thread from the bobbin, creating a tight and durable stitch.
• Heavy-Duty Sewing Capability: These machines are designed to handle heavy-duty sewing tasks. They have a robust construction and powerful motor to sew through thick materials, multiple layers, and challenging fabrics. They are commonly used in industries such as upholstery, automotive, leather goods manufacturing, and other applications that require sewing heavy fabrics or materials.
• Versatility: Compound feed lockstitch machines offer versatility in terms of stitch patterns and sewing applications. They can typically perform straight stitch, zigzag stitch, and other decorative stitches. They can be equipped with various presser feet, needle sizes, and thread types to accommodate different sewing needs.
• Durability and Reliability: Due to their industrial-grade construction, compound feed lockstitch machines are built to withstand continuous and demanding sewing conditions. They are known for their durability, reliability, and long-lasting performance in industrial settings.

Our company was formerly known as Changsha Double Star Gear Industrial Co., Ltd, which was established in 1994. It is a directly affiliated university-run enterprise founded by Central South University Professor Zeng Tao, the leading expert on spiral bevel gears in China. It was later renamed as Changsha Senjie Gear Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production R&D base specializing in professional design, reserch, manufacture and sales of high-quality small module spiral bevel gears and high reduction hypoid gears and cylindrical gears.
