Its main function is to simulate the actual working environment, ensure that the various parameters of the electric drum (such as speed, torque, temperature rise, noise, sealing, etc.) meet the design requirements, avoid problems after installation, and improve reliability and safety.

[0003] After searching, the Chinese patent with application number "CN202223167294.6" is specifically a test frame for an electric roller. The counterweight includes a fixed plate fixedly connected to the surface of the transmission belt. A connecting rod is fixed on the side of the fixed plate away from the transmission belt. A plurality of counterweight rings are arranged on the surface of the connecting rod.
