HJ-C21 High Speed for Black Out Cloth Cam Shedding

Product Show

Structural Integrity & Precision Engineering

The foundation of the HJ-C21 lies in its overall cast box structure and optimized mechanical design. Utilizing a Mazak horizontal flexible automatic production line for one-time clamping ensures that the associated dimensional accuracy remains exceptionally high. This meticulous machining process effectively dampens the mechanical vibration and reduces the acoustic noise during rapid equipment operation, creating a smoother and quieter factory environment. An optimized conjugate cam opening device further guarantees stable running even at peak speeds, significantly lowering long-term maintenance requirements. The unit is specifically calibrated for the demanding production of high-speed, wide-width, and heavy-weight fabrics, featuring a fast-placement oil connector that makes changing and draining lubricating fluids a quick, clean, and effortless task.

Versatile Fabric Adaptability

To meet the diverse demands of modern textile manufacturing, the maximum number of heald frames is configured to 14 pieces. This expansive capacity easily fulfills the intricate weaving needs of special varieties such as heavy blackout cloth, dense twill, and smooth satin. In practical application, this shedding mechanism is widely adaptable to over 150 different types of high-density fabrics, making it an indispensable asset for medium to large-scale efficient production runs. The ability to switch between different weave structures rapidly allows textile facilities to respond to shifting market trends and varied fabric orders with minimal downtime.

Safety & Environmental Design

The frame components are constructed from integrated steel plate bent beams and treated with industry-leading electrophoretic spraying technology. This advanced surface treatment provides a smooth, resilient finish that feels robust to the touch while delivering outstanding anti-corrosion and anti-rust capabilities. Combined with a fully enclosed protective cover, this design drastically improves the safety of workshop operators by isolating moving parts. Furthermore, the comprehensive waterproof sealing protects internal mechanisms from the humid environment typical of water jet weaving, ensuring the equipment's operational lifespan extends two to three times longer than comparable alternatives.
