With the continuous advancement of automation and intelligent technologies, unwinding mechanisms will become more efficient and stable in the future, further improving the overall performance and reliability of production lines. In short, through refined design and optimization, the unwinding process of endless conveyor belts has become more precise and stable, making it an indispensable component of modern production.

[0003] However, in the actual use of existing solutions, the raw material unwinding mechanism used in endless conveyor belt production may face problems such as unstable tension, excessive impact during startup and shutdown, and increased equipment wear. This can cause the conveyor belt to stretch, slip, or break, increasing repair and replacement costs and reducing the life of the equipment. Furthermore, the lack of precise damping control can lead to energy waste and reduced production efficiency due to uneven material delivery, unstable equipment operation, and even downtime. The system's adaptability is also limited, making it difficult to adjust the unwinding speed and tension according to different raw materials, thus affecting the flexibility and stability of the production line.

[0015] 1. This utility model describes a raw material unwinding mechanism for producing endless conveyor belts. An air pump, via a connecting tube, regulates the air pressure within an airbag, thereby driving the inward and outward movement of a damping rod. This adjusts the friction between the damping rod and the support rod, thereby adjusting the damping force and optimizing the performance of the endless conveyor belt unwinding mechanism.

The raw material unwinding mechanism for producing an endless conveyor belt described in this utility model uses a reel wheel with a sprocket to drive upper and lower opposing cleaning rollers to clean the base belt. This effectively removes impurities and residues from the base belt, keeping it clean, preventing blockage and slipping, and ensuring smooth operation of the conveyor belt. This not only reduces wear and damage to the equipment and extends the system's service life, but also reduces the burden of manual cleaning and improves production efficiency and continuity.
