AI Technical Summary
When the foamed particles are fed into the buffer tank, the unstable airflow of the high-pressure gas causes changes in the amount of air, which affects the working stability of the buffer tank.
A buffer device is adopted, including a buffer tank, a feed pipe, an air supply pipe, and a fan. The speed of the unloader is adjusted by changing the speed of the fan to ensure a stable ratio of air to particles in the buffer tank. A speed reducer and a filter screen are used to prevent particle blockage.
This achieves a stable ratio of air to particles within the buffer tank, ensuring the tank's operational stability and preventing shocks caused by changes in air volume.
