6B Sewing M/C Crossed Helical Gear For 6B Twin-Needle Machine

In a twin needle machine, the screw gear can play a role in the machine's overall functionality. While the specific placement and function of the screw gear may vary between different twin needle machine models, here are some general roles it can serve:

1. Power Transmission: The screw gear can be involved in power transmission within the machine. It transfers rotational motion from one component to another, often at a different angle or speed. It can help convert the rotary motion of the motor or other driving mechanism into the linear or reciprocating motion required for needle movement or other machine functions.
2. Needle Bar Movement: In some twin needle machines, the screw gear may be responsible for driving the movement of the needle bars. As the gear rotates, it converts the rotational motion into a linear or up-and-down motion, which in turn moves the needle bars. This allows the twin needles to penetrate the fabric and create stitches.
3. Timing and Synchronization: The screw gear can play a role in the timing and synchronization of the twin needle machine's components. It ensures that the needle bars move in a coordinated manner, maintaining proper alignment and spacing between the needles. This synchronization helps achieve parallel stitching and consistent stitch quality.
4. Feed System: Depending on the machine design, the screw gear might also be involved in driving the feed system. It can contribute to the movement of the feed dogs or other feeding mechanisms that advance the fabric during stitching. This ensures smooth and even fabric feeding for both needles.

A twin needle machine, also known as a double needle machine, is a type of sewing machine that is specifically designed to sew with two parallel needles simultaneously. This configuration allows for the creation of two parallel lines of stitching in a single pass. Here are some key features and characteristics of twin needle machines:

1. Twin Needle Capability: Twin needle machines are equipped with two needle bars and two needle positions, allowing for the use of two needles side by side.
2. Stitch Formation: With the twin needle setup, the machine can produce two parallel lines of stitching on the fabric. These parallel stitches can create decorative effects, topstitching, hemming, and other effects depending on the sewing application.
3. Needle Spacing: The distance between the two needles on a twin needle machine can usually be adjusted to achieve different needle spacing configurations. This allows for flexibility in creating different widths between the twin needle stitches.
4. Thread Tension Control: Twin needle machines typically have separate thread tension mechanisms for each needle, allowing for independent tension adjustment. This ensures balanced tension in both threads, resulting in even and consistent stitching.
5. Feed System: The feed system of a twin needle machine is designed to accommodate the twin needle configuration. The feed dogs or other feeding mechanisms work in tandem to move the fabric smoothly and consistently, ensuring accurate stitching.
6. Versatility: Twin needle machines are versatile and can be used for various sewing applications. They are commonly used for decorative stitching, topstitching, hemming, and creating parallel lines of stitching on a wide range of fabrics.

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.
